RESUMO
OBJECTIVE@#To investigate the method and clinical effects of the treatment of recurrent anterior dislocation of shoulder with Hill-Sachs injury by arthroscopic Bankart repair and Remplissage.@*METHODS@#From March 2016 to March 2019, 106 patients with recurrent anterior dislocation of shoulder with glenoid bone defect less than 20% underwent arthroscopic Bankart repair, including 76 males and 30 females, aged from 18 to 45 (27.3±8.6) years, 59 cases of left shoulder and 47 cases of right shoulder. Range of motion (ROM), American Shoulder and Elbow Surgeons(ASES) score, Constant-Murley score and Rowe score were used to evaluate shoulder functionand stability before and after operation.@*RESULTS@#All patients were followed up, and the duration ranged from 21 to 60 months, with a mean of (41.5± 8.5) months. One patient developed infection after operation, and the infection was controlled after arthroscopic debridement again. The remaining patients did not have clinical complications such as infection, intra articular hematocele and redislocation. Shoulder flexion and lifting increased from (158.33±15.72) ° preoperatively to (169.43±10.04) ° at the latest follow up, and internal rotation changed from T7 (T4 to T10) preoperatively to T8 (T5 to T10) at the latest follow up;the average lateral external rotation and abduction 90 ° external rotation decreased from (58.46±15.51) ° preoperatively and (99.37±14.09) ° to (53.18±14.90) ° and (92.52±13.10) ° at the latest follow up, respectively. The ASES score, Constant -Murley score and Rowe score were significantly improved.@*CONCLUSION@#The clinical effect of rehabilitation of Bankart repair combined with Remplissageunder arthroscopy in the treatment of recurrent dislocation of shoulder joint in adults with Hill-Sachs defect is satisfactory. Although the external rotation function is weaker than that before operation, it can effectively reconstruct the shoulder function and avoid the occurrence ofdislocation after operation.

Glioma is the most common intracranial malignant tumor of the nervous system. It is highly invasive, resistant to conventional treatment, and easy to relapse. The main treatment strategy is surgery plus radiotherapy, but the prognosis is still poor. Glioma stem cells (GSCs) are a group of cells with neural stem cell-like properties in glioma. As the starting cells of glioma, they are considered to be the key factors for tumorigenesis and recurrence. CD133 is considered to be a biomarker for glioblastoma and is used as a marker for GSCs. Although its biological significance is currently controversial, more and more studies have shown that CD133 is involved in GSCs-mediated tumor formation and recurrence. This article mainly reviews the GSCs surface marker CD133 and its related targeted therapies.
RESUMO
Objective To observe the effect of risperidone on serum brain derived neurotrophic factor ( BDNF) in first-episode schizophrenic patients. Methods In the treatment group, 90 first-episode schizophrenics were treated with risperidone for 16 weeks, and the dose of risperidone was (3.79±0.88) mg·d-1. Serum BDNF levels were measured before treatment, at 2, 8, and 16 weeks after treatment. The severity of schizophrenia symptoms was assessed by the positive and negative symptom scale ( PANSS) before and after sixteen weeks of treatment. Serum BDNF concentrations were measured in 90 healthy controls. Results BDNF in the control group was (22.867±6.051) ng·mL-1. The serum BDNF levels before treatment and at the end of week 2, 8, 16 after the treatment in the treatment group were (14.256±4.096), (13.078±3.462), (18.001±5.753), (21.089± 6.692) ng·mL-1 , and the serum BDNF level was significantly lower in the treatment group than that in the control group ( P<0.01) . After the treatment, the level of BDNF in the treatment group decreased at first and then increased, compared with that before treatment, the difference was significantly ( P<0.05 or P<0.01) . The level of BDNF in the treatment group at the end of week 16 was not significantly different from that of the control group ( P>0.05) . After treatment, the total score of PANSS scale and its subscales decreased, the difference was significantly (P<0.01). At the end of week 16, the PANSS subscale reduction rate was positively correlated to the serum BDNF concentration change (r=0.499, P=0.001). The change rate of serum BDNF concentration at the end of week 16 was not correlated with the dose of risperidone (r=0.103, P=0.335). Conclusion BDNF is abnormal in the first episode of schizophrenia, which can be improved by risperidone treatment.
