Clinical trials

The purpose of this clinical trial is to learn if allogeneic cord blood-derived CAR-T cell drug works to treat Multiple Myeloma (MM) including Bone-related extramedullary (EMB) disease and extramedullary extraosseous disease(EME) in adults. It will also learn about the safety of the allogeneic cord blood-derived CAR-T cell drug. The main questions it aims to answer are: 1. What adverse events occur and the incidence rate of DLTs within 28 days and UCAR-T-related AEs within 28 days after the allogeneic cord blood-derived CAR-T cell injection for multiple myeloma (MM)? 2. Which dose level is the optimal biological dose (OBD)? 3. What is the overall responserate (ORR), including stringent complete response (sCR), completeresponse (CR),very good partial response (VGPR), partial response (PR), minimal Response (MR) and DOR, PFS, RFS, OS? Participants will: 1. be pretreated with FC regimen, fludarabine (30mg/m²/d, days -5, -4, and -3) and cyclophosphamide (300\~500 mg/m²/d, day -5,-4, and -3). 2. rest for 2 days on Day-2 and Day-1. Tumor burden should be re-evaluated and chemotherapy side effects assessment. 3. receive allogeneic cord blood-derived CAR-T cells infusion 4. Visit the clinic at D28, 1 month, 2 months, 3 months, 4 months, 6 months, 9 months and 1 year after CAR-T cells infusion.

The purpose of the study is to evaluate the efficacy of acupuncture in treating Parkinson's disease related constipation (PDC). In the randomized controlled clinical trial study, patients meeting the criteria for inclusion will be randomly enrolled and divided into two groups in a 1:1 ratio: the acupuncture group and the sham acupuncture group. The intervention is going to be executed using the acupoints EX-HN1（Sishencong),LI4 (Hegu),ST25 (Tianshu),ST37(Shangjuxu),ST36(Zusanli),ST44 (Neiting), ST44 (Taichong), SP6 (Sanyinjiao) and CV4 (Shuangyuan).The acupuncture needles will be inserted to a depth of 0.8 to 1 cm in the acupuncture group. The sham acupuncture group's needles will be inserted to a depth of 0.2 to 0.3 cm with nonacupuncture points located 0.5 cm in lateral to the real acupoint or to the right for midline points. During the study, researchers will observe changes in complete spontaneous bowel movements (CSBMs), Constipation Symptom and Efficacy Assessment Scale (CSEAS) (including the six dimensions of difficulty, Bristol, time, incompleteness, frequency,and bloating), the Patient-Assessment of Constipation Quality of Life questionnaire (PAC-QOL), and the Unified Parkinson's Disease Rating Scale (UPDRS) at baseline (week 0), post-treatment (week 4), and follow-up (week 12).Colonic transit time measurement and conventional anorectal manometry were evaluated at the above time points.

Objective: To observe the practical application of the standardized green channel treatment system for stroke in Xi 'an in the real world. Methods: Clinical data and information of patients with acute ischemic stroke who received standardized green channel treatment for stroke were collected, and a multicenter observational clinical study was carried out in the real world to evaluate the prognosis, mortality, incidence of asymptomatic and symptomatic cerebral hemorrhage, incidence of pneumonia, and recurrence rate of stroke after 90 days.

Benign paroxysmal positional vertigo (BPPV) is the most common peripheral vestibular disorder, and currently, manual repositioning techniques are often used for treatment. However, up to 30%-50% of patients may experience residual symptoms such as non-rotational dizziness, heaviness, instability, and emotional disturbances even after successful repositioning, which significantly impacts their daily functioning and quality of life. Electroacupuncture therapy has been proven to be an effective treatment for dizziness and has been applied to various vestibular disorder patients. However, the efficacy of electroacupuncture on the residual effects of successfully repositioned BPPV patients remains unclear. This study aims to explore the effectiveness of three regimens: electroacupuncture, betahistine in patients with residual symptoms after successful manual repositioning.

This observational study focus on a new parameter of cerebral perfusion derived form digital substraction angiography.

To evaluate the efficacy and safety of head acupuncture combined with endovascular therapy for cerebral infarction compared with endovascular therapy alone
