Clinical trials

Healthy donors are commonly mobilized with granulocyte colony-stimulating factor (G-CSF) to collect peripheral blood stem cells for allogeneic hematopoietic stem cell transplantation (allo-HSCT). However, the efficiency of mobilization varies among donors, and suboptimal mobilization may require additional collection procedures or rescue strategies. This prospective, multicenter, randomized trial evaluates whether the timing of daily G-CSF administration (morning vs evening) affects the level of circulating CD34+ cells prior to apheresis in healthy donors. Participants will be randomly assigned to receive subcutaneous G-CSF 10 μg/kg once daily for 5 consecutive days either at 08:00 (±15 minutes) or at 20:00 (±15 minutes). The primary endpoint is the peripheral blood CD34+ cell count measured approximately 12 hours after the last G-CSF dose and within 60 minutes before the start of the first apheresis session. Secondary endpoints include collection efficiency and CD34+ yield metrics, the proportion of donors achieving the target CD34+ dose on the first collection day, the need for a second collection day, and donor safety outcomes. The goal of the study is to identify a practical dosing schedule that may improve stem cell mobilization and streamline donor collection procedures.

This is a multicenter, randomized, double-blind, placebo-controlled clinical trial evaluating the efficacy and safety of finerenone, a nonsteroidal mineralocorticoid receptor antagonist, for the early regression of albuminuria in adults with type 2 diabetes mellitus and chronic kidney disease (eGFR \>= 30 mL/min/1.73 m\^2 and UACR 30-2000 mg/g) who are already receiving a maximum tolerated dose of an ACE inhibitor or ARB. A total of 148 participants are randomized 1:1, stratified by baseline UACR (\<300 vs \>=300 mg/g), to oral finerenone (10 or 20 mg once daily, titrated by serum potassium and eGFR) or matching placebo, on top of standard background therapy, for 180 days, followed by a 30-day off-treatment follow-up. Albuminuria regression is defined as both an improvement in Kidney Disease: Improving Global Outcomes albuminuria category, from A3 to A2 or A1, or from A2 to A1, and a more than 30% reduction in urinary albumin-to-creatinine ratio from baseline. The outcome will be reported as the percentage of participants meeting this definition at Day 180.

This project is based on the biphasic instability model and social timing theory, utilizing IPSRT to help regulate social interactions and establish regular daily habits, alleviate emotional symptoms, and prevent. The included patients with bipolar II disorder who did not take medication for the first time or relapsed within the past month were randomly divided into a medication only group (Q group), a only IPSRT group (I group). Group Q received treatment with quetiapine alone (starting at 50mg/day, with an additional 50mg to 300mg/day per week, and the dosage can be flexibly adjusted); Group I received 12 weeks of interpersonal and social rhythm therapy (12 sessions, once a week, 40 minutes each time, with relatively fixed tasks and agendas for each meeting). Compare the changes in various clinical evaluation scales and skin potential before and after treatment, explore the safety and effectiveness of drug therapy and psychotherapy for patients with bipolar II disorder with rhythm disorders, and investigate the potential biological mechanism of IPSRT by collecting data on salivary cortisol and melatonin, peripheral circadian rhythm genes (PER1/PER2/PER3/BMAL1), and magnetic resonance.

Investigators will compare BY002 to a placebo (a pharmacologically inactive substance) to assess the safety and tolerability of BY002 in healthy subjects. Participants will undergo: 1. Single/multiple subcutaneous (SC) administrations of BY002/placebo 2. A 7-day safety follow-up period following the last dose

HIV viral reservoirs represent the major barrier to curing AIDS, and effectively reducing viral reservoirs in people living with HIV through different strategies has become a research priority in the HIV field. Ipilimumab-tovorafenib monoclonal antibody injection (Aituo combination antibody, QL1706) contains two engineered monoclonal antibodies targeting PD-1 and CTLA-4. Chidamide is the first independently developed histone deacetylase inhibitor in China. This study aims to evaluate the safety and efficacy of Aituo combination antibody combined with chidamide in people living with HIV. This study adopts a modified "1+3+3" dose-escalation design. Initially, one participant will be enrolled at dose level 1 (DL1) for safety observation. If the treatment is well tolerated, the study will proceed to a standard 3+3 design, with sequential dose escalation to DL2 and DL3. Three dose levels are planned: DL1, the starting dose, consists of ipilimumab-tovorafenib monoclonal antibody injection at 0.3 mg/kg once every 4 weeks ± 1 day for a total of three doses, in combination with chidamide 10 mg orally twice weekly for 12 weeks. DL2 consists of ipilimumab-tovorafenib monoclonal antibody injection at 1 mg/kg once every 4 weeks ± 1 day for a total of three doses, in combination with chidamide 10 mg orally twice weekly for 12 weeks. DL3 consists of ipilimumab-tovorafenib monoclonal antibody injection at 2 mg/kg once every 4 weeks ± 1 day for a total of three doses, in combination with chidamide 10 mg orally twice weekly for 12 weeks. During dose escalation, progression to the next dose level or discontinuation of escalation will be determined according to the occurrence of dose-limiting toxicities (DLTs). The DLT observation window is 28 days after the first dose. Participants evaluable for DLT are those who complete the observation window or experience a DLT. After completion of dose escalation, the maximum tolerated dose (MTD) will be determined based on safety and tolerability. If the MTD is not reached, DL3 will be selected as the dose for subsequent study. After determination of the MTD or the subsequent study dose, an additional 11 participants will be enrolled at that dose level to further evaluate safety, tolerability, and preliminary efficacy. The maximum total sample size of the study will be 29 participants.

This study is a multicenter cross-sectional observational study, aiming to include approximately 200 patients aged 18-75 years who are using hydrocodone sustained-release tablets or oxycodone sustained-release tablets for pain management of moderate to severe cancer pain. Baseline information, tumor history, and comorbidities of the subjects will be collected through electronic patient-reported outcomes (ePRO), and the pain condition will be evaluated using BPI, acute pain assessment tools, etc. Sleep-related indicators will be collected using Huawei smart wearable devices and PSQI, ISI scales. Psychological emotional states will be assessed using NCCN psychological distress thermometer, HAMA, HAMD, etc. Blood samples will also be collected for relevant tests. The study sets up a screening baseline assessment period, a 1-week assessment period, and 1-month and 3-month follow-up periods after enrollment. The changes in relevant indicators will be tracked throughout the process, aiming to quantify the association between pain and insomnia, anxiety and depression, and to verify the potential mediating role of sleep disorders between pain and emotional disorders, providing a basis for optimizing the comprehensive symptom management of cancer pain patients.

Background: Gastric cancer remains a significant health burden globally, particularly in China, where the majority of patients present with advanced disease at diagnosis. While immune checkpoint inhibitors (ICIs) targeting PD-1 have revolutionized treatment for various malignancies, their efficacy in proficient mismatch repair (pMMR) or microsatellite stable (MSS) gastric cancer-which constitutes over 85% of cases-remains limited. Recent Phase III trials (CheckMate 649, ATTRACTION-04, Orient-16) have demonstrated that combining PD-1 inhibitors with chemotherapy improves outcomes in advanced gastric cancer, leading to approved indications. However, the benefit in pMMR/MSS populations is modest, highlighting an urgent need for novel combination strategies to overcome immunotherapy resistance. Preclinical research published in Nature (Liu et al., 2020) revealed that inhibiting PCSK9 (Proprotein Convertase Subtilisin/Kexin type 9)-a key regulator of cholesterol metabolism-can potentiate immune checkpoint therapy through a novel mechanism independent of its lipid-lowering function. PCSK9 inhibition was shown to increase tumor cell surface expression of MHC class I molecules by preventing their lysosomal degradation, thereby enhancing tumor antigen presentation and promoting cytotoxic T lymphocyte infiltration. This mechanistic insight suggests that combining a PCSK9 inhibitor with PD-1 blockade could synergistically improve antitumor immunity, particularly in immunologically "cold" tumors like pMMR/MSS gastric cancer. Tafolecimab is the first domestically developed fully humanized PCSK9 monoclonal antibody approved in China for hypercholesterolemia, with a favorable safety profile and extended half-life. Based on this strong preclinical rationale and the established efficacy of PD-1 plus chemotherapy in gastric cancer, this investigator-initiated trial aims to clinically translate the concept of PCSK9 inhibition as an immunomodulatory strategy. Study Population: This study will enroll 30 patients with the following key eligibility criteria: Inclusion: Adults aged 18-75 years with histologically confirmed pMMR/MSS gastric or gastroesophageal junction adenocarcinoma; initially unresectable or advanced disease (including metastatic); ECOG performance status 0-1; measurable disease per RECIST v1.1; adequate organ function. Exclusion: HER2-positive, EBER-positive, or CLDN18.2-positive tumors; prior systemic anticancer therapy for advanced disease; active autoimmune disease requiring immunosuppression; uncontrolled intercurrent illness; LDL-C \<30 mg/dL; history of PCSK9 inhibitor allergy; prior exposure to anti-PD-1/PD-L1 or PCSK9-targeted therapies. Study Objectives: This is a multicenter, prospective, single-arm exploratory trial with a safety run-in phase (first 6 patients monitored for dose-limiting toxicities). The treatment regimen consists of: Sintilimab (PD-1 inhibitor): 200 mg IV, day 1, every 3 weeks (Q3W) Tafolecimab (PCSK9 inhibitor): 300 mg subcutaneous injection, day 1, Q3W (dose reduction to 150 mg if DLTs occur) SOX chemotherapy: Oxaliplatin 130 mg/m² IV, day 1 + S-1 40 mg/m² orally twice daily, days 1-14, Q3W cycles Treatment continues until disease progression, unacceptable toxicity, or withdrawal of consent. Primary Endpoint: Objective Response Rate (ORR) assessed by RECIST v1.1 Secondary Endpoints: Progression-Free Survival (PFS) Disease Control Rate (DCR) Conversion surgery rate and R0 resection rate Pathological Complete Response (pCR) and Major Pathological Response (MPR) rates in resected patients Overall Survival (OS) Safety and tolerability (incidence of TRAEs, ≥Grade 3 AEs, irAEs per CTCAE v5.0) Exploratory Endpoints: Association between tumor biomarkers (including PD-L1 CPS, H. pylori infection status, and tumor PCSK9 expression) and treatment efficacy Multi-omics analyses using paired pre- and post-treatment tumor tissue, peripheral blood, and fecal samples Sample Size and Duration: A fixed sample size of 30 patients will be recruited over approximately 12 months, with survival follow-up extending to 36 months. This exploratory study is designed to generate preliminary efficacy and safety signals to inform future larger-scale investigations. The safety run-in design ensures close monitoring for potential additive toxicities, particularly given the novel combination of PCSK9 inhibition with immunotherapy and chemotherapy.

The goal of this clinical trial is to learn if inulin and spirulina, used alone or in combination, can improve insomnia disorder in adults aged 18 to 60 years with chronic insomnia disorder. It will also learn about the safety of these interventions. The main questions it aims to answer are: Does inulin plus spirulina improve sleep quality, as measured by the reduction rate in Pittsburgh Sleep Quality Index (PSQI) score? Does the intervention improve sleep-related, mood, anxiety, and cognitive outcomes after 12 weeks? Researchers will compare an inulin group, a spirulina group, a combined inulin plus spirulina group, and a placebo group to see if the combined intervention provides greater benefit than either single intervention or placebo. Participants will: be randomly assigned to 1 of 4 groups: inulin, spirulina, inulin plus spirulina, or placebo; take the assigned study product once daily for 12 weeks; complete sleep, mood, anxiety, and cognitive assessments at baseline and week 12; undergo polysomnography and provide blood and stool samples at baseline and week 12; and be monitored for adverse events throughout the study.

This study aims to investigate the safety and preliminary efficacy of an innovative therapeutic strategy combining chidamide with NKG2D-directed chimeric antigen receptor natural killer (CAR-NK) cells in individuals living with HIV. The approach is predicated on the "shock and kill" paradigm: chidamide is employed to reactivate latent HIV reservoirs and upregulate surface target ligands (NKG2D ligands) on infected cells; subsequently, allogeneic NKG2D CAR-NK cells are infused to specifically recognize and eliminate these "marked" cells. This is a phase I, open-label, single-arm clinical trial comprising two distinct stages: a dose-escalation phase (phase Ia, utilizing a "1+3+3" design) and a dose-expansion phase (phase Ib). A total of 20 HIV-infected individuals who are stable on antiretroviral therapy (ART) and have suppressed plasma viremia are planned for enrollment. Participants will receive oral chidamide over approximately five weeks, followed by two cycles of intravenous CAR-NK cell infusion. The primary endpoint is the safety and tolerability of the regimen, with particular attention to immune-related adverse events including cytokine release syndrome (CRS). Secondary endpoints encompass exploratory assessments of potential virologic and immunologic effects, such as alterations in plasma HIV RNA, cell-associated viral nucleic acids, and CD4+ T-cell counts. This study is intended to provide initial human safety data and preliminary evidence regarding the potential of this combination strategy to contribute toward a functional cure for HIV infection.

The goal of this clinical trial is to learn if Bifidobacterium PB-18 can treat mild to moderate depressive disorder in adults aged 18 to 65 years who are not taking antidepressants or other psychotropic medications during the study. It will also learn about the safety of Bifidobacterium PB-18 and explore its potential effects on the gut-brain axis. The main questions it aims to answer are: Does Bifidobacterium PB-18 increase the response rate at Week 8, defined as a reduction of at least 50% from baseline in the 17-item Hamilton Depression Rating Scale (HAMD-17)? What adverse events occur in participants receiving Bifidobacterium PB-18? How do gut microbiota, metabolite profiles, and related biological markers change after treatment with Bifidobacterium PB-18? Researchers will compare Bifidobacterium PB-18 with a placebo, a look-alike powder that does not contain PB-18, to see if Bifidobacterium PB-18 improves depressive symptoms. Participants will: Be randomly assigned to receive Bifidobacterium PB-18 or placebo in a 1:1 ratio Take the assigned study product once daily for 8 weeks Visit the study site at baseline, Week 4, and Week 8 for symptom and safety assessments Complete study questionnaires, including HAMD-17, HAMA, PSQI, and CBCT Provide blood and stool samples at baseline and Week 8 for exploratory biological analyses

This is a randomized, double-blind, placebo-controlled, parallel-group, prospective, multi-center clinical trial, to evaluate the efficacy of silkworm pupa tablets in improving nutritional status and sarcopenia in patients with malignancies who have completed comprehensive treatment. All participants will be randomly assigned (1:1) to either experimental group (n=240): dietary advice + Wanshili Longbao Silkworm Pupa Tablets (main ingredients: freeze-dried active mulberry cocoon pupa powder, maltitol, milk mineral salt, mannitol, maltodextrin), 2 tablets three times daily before meals for 3 months, or control group (n=240): dietary advice + placebo (identical appearance), 2 tablets three times daily before meals for 3 months. The primary endpoint is sarcopenia prevalence at 3 months (based on AWGS 2019 criteria: muscle strength, muscle mass, and physical function).

The goal of this observational study is to develop and validate a deep learning model to dynamically assess postoperative bleeding risk and assist in decision-making for re-operation in adult patients (≥18 years) diagnosed with primary gastric cancer undergoing radical gastrectomy. The main question\[s\] it aims to answer \[is/are\]: Can an AI model based on perioperative dynamic physiological parameters and precise intraoperative blood loss accurately predict the risk of postoperative bleeding requiring re-operation? Does the application of this AI model improve clinical decision-making (e.g., earlier warning time, optimal intervention timing) and patient outcomes (e.g., mortality, length of stay)? Since there is no comparison group (this is a pure observational study without intervention arms), researchers will not compare different treatment groups. Instead, the investigators will evaluate the model's performance (sensitivity, negative predictive value, AUC, calibration) using retrospective data for training and prospective multi-center data for external validation. Participants will: Undergo standard radical gastrectomy and routine postoperative care as per clinical practice (no study-specific interventions). Have their perioperative data collected, including demographics, medical history, vital signs, laboratory tests (blood gas analysis), surgical details, and precise intraoperative blood loss measurements. (For prospective participants only) Provide informed consent and complete follow-up assessments up to 30 days post-surgery.

The purpose of this study was to evaluate the diagnostic efficacy and prognostic value of 18F-FAPI PET/CT combined with multiparameter MRI in gastric cancer.

Background and Significance: Colorectal cancer (CRC) ranks as the third most common cancer and the second leading cause of cancer-related deaths globally. Despite improved early screening rates, a significant proportion of newly diagnosed CRC patients present with synchronous metastases, predominantly liver metastases. The concept of oligometastases, introduced by Hellman and Weichselbaum in 1995, describes a transitional state between localized disease and widespread metastases, characterized by limited metastatic lesions (typically 1-5) confined to 1-2 organs. Current Treatment Landscape: The management of oligometastatic disease combines local therapeutic approaches (surgery, radiotherapy, radiofrequency ablation) with systemic treatments, aiming to achieve No Evidence of Disease (NED) status. The ESMO guidelines officially categorized metastatic CRC into oligometastatic and widespread metastatic states in 2016, emphasizing the importance of integrated local and systemic treatments for oligometastatic colorectal liver metastases (CRLM). Treatment Evolution and Challenges: While the EPOC study established CAPEOX neoadjuvant chemotherapy followed by R0 resection as the standard treatment for initially resectable CRLM, patients with synchronous rectal cancer oligometastases present unique challenges due to complex local anatomy and high local recurrence risks. Although various neoadjuvant approaches, including Total Neoadjuvant Therapy (TNT), have been studied, they have not demonstrated significant long-term survival benefits, primarily because distant metastases impact survival more significantly than local recurrence. Innovative Approach: Recent success with Immunotherapy-Based Total Neoadjuvant Therapy (iTNT) in microsatellite stable/proficient mismatch repair (MSS/pMMR) locally advanced rectal cancer has shown promising results. Short-course radiotherapy (SCRT) combined with chemotherapy and immunotherapy has demonstrated superior efficacy trends, attributed to radiation's immune-activating effects on both local and distant tumor microenvironments. Research Objective: This project aims to evaluate the effectiveness of iTNT combined with SCRT in MSS/pMMR rectal cancer patients with synchronous oligometastases. The novel approach integrates SCRT with CAPEOX chemotherapy and Serplulimab, potentially improving complete response rates, organ preservation opportunities, and overall treatment efficacy while reducing recurrence risks. This pioneering study represents the first investigation of iTNT in synchronous rectal cancer oligometastases, offering a potentially transformative treatment strategy for this challenging patient population. Research Innovation: The study uniquely combines SCRT, CAPEOX chemotherapy, and Serplulimab in a neoadjuvant setting for MSS/pMMR synchronous rectal cancer oligometastases, addressing an unmet clinical need and potentially establishing a new treatment paradigm in this field.

Allogeneic Hematopoietic Cell Transplantation (Allo-HCT) serves as a curative treatment modality for the vast majority of patients with hematological malignancies. Historically, due to the relatively high treatment-related mortality rate associated with Allo-HCT, this therapy was primarily administered to younger patients. However, the median age at onset of most hematological malignancies falls within the elderly population. For instance, the median ages at onset of Acute Myeloid Leukemia (AML) and Myelodysplastic Syndrome (MDS) are 68 and 77 years, respectively. In recent years, with the advancement of transplantation techniques and the application of Reduced-intensity Conditioning (RIC) regimens, a growing number of elderly patients have undergone Allo-HCT. Data from the Center for International Blood and Marrow Transplant Research (CIBMTR) indicate that in 2017, 31% of patients who received Allo-HCT were aged over 60 years, and 6% were over 70 years old. Over the past decade, the number of elderly patients undergoing Allo-HCT has increased significantly. Given that most elderly patients cannot tolerate conventional myeloablative conditioning regimens, RIC regimens based on Fludarabine (Flu) combined with Busulfan (Bu), or Fludarabine (Flu) combined with Melphalan (Mel) are currently widely used in elderly patients undergoing Allo-HCT. Nevertheless, the post-transplant relapse rate remains as high as 30%-55%, and the long-term GVHD-free and Relapse-free Survival (GRFS) rate fluctuates between 21% and 59%, suggesting that the efficacy of transplantation needs to be further improved. Further comparison of the commonly used RIC regimens in elderly patients-namely Flu+Bu (2-day), Flu+Bu (4-day) and Flu+Mel-has demonstrated that the Flu+Mel regimen yields superior transplantation outcomes over the Flu+Bu regimens. At present, the optimal RIC regimen for elderly patients with hematological malignancies has not yet been clearly defined. The selection of transplantation conditioning regimens for elderly patients should strike a balance between reducing non-relapse mortality and decreasing post-transplant relapse. Over the past 20 years, an increasing number of targeted drugs acting on specific cellular signaling pathways, anti-apoptotic proteins, epigenetic regulators, and monoclonal antibodies have been introduced into clinical practice, thereby revolutionizing the treatment landscape of hematological malignancies. These novel targeted therapies not only bring hope of achieving remission to patients with hematological tumors resistant to traditional chemotherapy, but also the combined application of novel drugs and Allo-HCT is bound to fundamentally transform the overall technical system of hematopoietic stem cell transplantation. Venetoclax is a potent and selective oral inhibitor targeting the BH3 domain of the anti-apoptotic protein Bcl-2. In 2018, the FDA approved Venetoclax as a first-line induction chemotherapy agent for elderly AML patient's ineligible for intensive chemotherapy, with a complete remission rate of up to 67% and favorable tolerability¹¹. Preclinical studies using Allo-HCT animal models have confirmed that the addition of a Bcl-2 inhibitor to RIC regimens can promote donor cell engraftment, reduce the incidence of GVHD, without impairing the graft-versus-leukemia (GVL) effect¹². In recent years, clinical trials have reported the efficacy and safety of the conditioning regimen combining Venetoclax with Flu+Bu in patients with myeloid malignancies undergoing Allo-HCT. Our research center has demonstrated the favorable safety profile and promising long-term survival outcomes of the Venetoclax plus Flu+Mel conditioning regimen in a phase II clinical trial involving patients aged over 50 years with AML/MDS undergoing Allo-HCT (2024 EBMT Poster B093; 2025 EBMT Poster B126). However, the long-term superiority of this novel regimen over the conventional Flu+Mel conditioning regimen remains to be clarified. Therefore, based on the existing findings from clinical studies and Allo-HCT animal model research, we hypothesize that incorporating Venetoclax into the Fludarabine+Melphalan conditioning regimen for elderly patients undergoing Allo-HCT is expected to improve long-term post-transplant survival and further enhance the transplantation efficacy in this patient population.

Patients were enrolled according to predefined inclusion and exclusion criteria. Following surgical admission, standard monitoring was initiated, including continuous assessment of heart rate, blood pressure, electrocardiogram (ECG), and peripheral capillary oxygen saturation (SpO₂). A peripheral intravenous line was established. Bispectral index (BIS) monitoring was performed continuously using a BIS monitor to assess frontal lobe electroencephalographic activity. Based on the type of surgical procedure, regional nerve block was administered. Upon confirmation of adequate block efficacy, patients were assigned to treatment groups according to sealed envelope randomization, and corresponding intravenous sedative regimens were initiated. Sedative induction agents were administered as follows: Group A received remimazolam at 0.08 mg/kg; Group B received dexmedetomidine at 1 μg/kg over 10 minutes; Group C received midazolam at 0.05 mg/kg. Maintenance infusions were as follows: Group A received remimazolam at 1 mg/kg·h; Group B received dexmedetomidine at 0.2-0.7 μg/kg·h; for Group C, if consciousness was not sufficiently suppressed with the initial dose, midazolam was supplemented in increments of 0.01 mg/kg, not exceeding a total dose of 0.1 mg/kg. Following induction, sedation depth was assessed every 2 minutes using the Observer's Assessment of Alertness/Sedation (OAA/S) scale, with auditory stimulation applied every 30 seconds until the patient no longer responded. The time to loss of response to auditory stimuli and the time to loss of consciousness were recorded. Surgical intervention was then performed. Ten minutes prior to anticipated completion of surgery, sedative infusion was discontinued. Sedation depth was reassessed every 2 minutes using the OAA/S scale, with repeated auditory stimulation every 30 seconds to determine the time to return of response and time to recovery of consciousness. If the patient had not achieved an OAA/S score of 5 within 30 minutes after discontinuation of sedation, flumazenil was administered as a reversal agent. Once the OAA/S score reached 5 or spontaneous responses to auditory stimuli were observed-indicating transition back to a responsive state-and complete electroencephalographic data had been collected, no further intervention was required.

This study employs a prospective, randomized, double-blind, placebo-controlled design. It aims to compare the efficacy of etamsylate versus placebo in preventing bleeding complications in patients with thrombocytopenia following hematopoietic stem cell transplantation.

This is a multi-center, prospective cohort study. The main purpose of Cohort A is to evaluate the efficacy and safety of Orelabrutinib combined with BR (bendamustine and rituximab) for previously untreated young patients with MZL; the purpose of Cohort B is to assess the efficacy and safety of Orelabrutinib combined with G (Obinutuzumab) followed by Orelabrutinib maintenance therapy for previously untreated elderly patients with MZL.

Bronchoscopy is currently widely used for the diagnosis and treatment of various respiratory diseases. However, the operation of bronchoscopy is irritating, causes a strong stress response, and shares the airway with the patient, making the patient highly susceptible to respiratory and cardiovascular risks. Among these risks, hypoxia is the most common adverse event.Different drug regimens can be selected for anesthesia under deep sedation. The combination of analgesic agents can help reduce coughing during bronchoscopy. Therefore, we employ a combination of sedative and analgesic drugs for painless bronchoscopy procedures. Among sedatives, propofol is the most commonly used. However, due to its disadvantages, such as respiratory and circulatory depression, we have introduced a novel approach combining remimazolam for sedation. The aim is to investigate whether this new regimen, compared to traditional propofol-based sedation, can reduce the incidence of hypoxia, minimize circulatory depression, and lead to faster postoperative awakening and recovery. Additionally, we hope to observe fewer adverse events, such as perioperative nausea and vomiting, excessive secretions, dizziness, and chills.

Bipolar disorder is a highly disabling psychiatric illness, and cognitive impairment is common in patients with bipolar depression as well as during remission, contributing substantially to functional disability and poorer prognosis. Currently, effective interventions specifically targeting cognitive deficits remain limited, highlighting the need for novel treatment strategies. Transcranial magnetic stimulation, a noninvasive neuromodulation technique, has shown potential benefits for depressive symptoms and cognitive functioning. Based on structural and functional neuroimaging evidence, this study proposes an individualized intermittent theta burst stimulation (iTBS) protocol targeting the primary visual cortex (V1) and its functional pathway to the hippocampus, combined with online cognitive training. This randomized, double-blind, parallel-group, sham-controlled trial will enroll 88 patients with bipolar disorder in remission phase and allocate them to active or sham stimulation. The intervention will be delivered over 5 days, with follow-up assessments through 6 weeks. The primary outcome is change in cognitive performance as measured by the Cambridge Neuropsychological Test Automated Battery (CANTAB). Secondary outcomes include changes in clinical symptom ratings, magnetic resonance imaging (MRI) biomarkers, and the incidence of adverse events. This study aims to evaluate the efficacy and safety of this targeted intervention and to provide evidence for precision treatment approaches to cognitive impairment in bipolar disorder.

This clinical trial aims to evaluate whether molecular MRD-guided chemotherapy can effectively treat FLT3-ITD mutated AML and potentially replace allogeneic hematopoietic stem cell transplantation. It primarily seeks to answer: * What is the complete remission rate after initial induction with Gilteritinib, Venetoclax, and Azacitidine? * What are the survival rates and safety of subsequent high-dose cytarabine consolidation after two cycles of this induction therapy? As a single-arm study, outcomes will be compared against historical data from standard treatments (including transplant) to assess if the new strategy is equally or more effective. Participants will: * Undergo three cycles of high-dose cytarabine consolidation after two cycles of induction therapy, contingent upon achieving deep FLT3-ITD molecular remission. * Start Gilteritinib maintenance therapy after consolidation if FLT3-ITD remains detectable, continuing until deep molecular remission is achieved again.

This phase II trial tests how well VA alternating with low-dose CHA works in treating unfit patients with newly diagnosed acute myeloid leukemia (AML). This is a prospective, multi-centers, single arm phase II study aimed to overcome VEN resistance and achieve greater MRD negative rate, providing better control of treatment for unfit AML.
