Objective To explore the interventional effect of repetitive transcranial magnetic stimulation (rTMS) on tardive dyskinesia (TD) in schizophrenic patients. Methods A total of 105 schizophrenic patients were selected as subjects and randomly divided into 1 Hz treatment group, 10 Hz treatment group and control group, with 35 patients in each group. All three groups received rTMS treatment for 12 weeks. The Abnormal Involuntary Movement Scale (AIMS), Scale for the Assessment of Negative Symptoms (SANS), Positive and Negative Syndrome Scale (PANSS) and Treatment Emergent Symptom Scale (TESS) scores were compared among the three groups. Physiological indicators such as electrocardiogram, blood routine, blood biochemistry and hormone levels were monitored. Results After treatment, the total AIMS scores in the 1 Hz and 10 Hz treatment groups were significantly lower than before treatment, and those in the 1 Hz and 10 Hz treatment groups were significantly lower than those in the control group (P < 0.05). The reduction rates of AIMS scores in the 1 Hz and 10 Hz treatment groups were 68.6% and 65.7%, respectively, which were significantly higher than the 22.9% in the control group (P < 0.05). After treatment, the total SANS and PANSS scores in the 1 Hz and 10 Hz treatment groups were significantly lower than before treatment, and those in the 1 Hz and 10 Hz treatment groups were significantly lower than those in the control group (P < 0.05). There was no statistically significant difference in the total AIMS score, efficacy and total PANSS score between the 1 Hz and 10 Hz treatment groups (P>0.05). There were no significant differences in the total TESS scores and physiological indicators among the three groups before and after treatment (P>0.05). Conclusion Both 1 Hz and 10 Hz rTMS can effectively improve TD in schizophrenic patients with good safety and have no significant side effects or physiological damage.

Objective To investigate the clinical effect of anterograde percutaneous screw fixation under robot navigation in the treatment of acetabular anterior column fractures.Methods A retrospective analysis was made on 7 cases of anterior acetabular column fractures from April 2021 to January 2023.The traction reduction was conducted by using pelvic"double reverse"traction table,the orthopedic robot-assisted design was carried out to plan the screw entry point and direction,and the antegrade channel cannulated screw was used for internal fixation.Results The operation time was 60-95 min(mean,78 min).The intraoperative blood loss was 5-20 ml(mean,8.6 ml).The number of fluoroscopy was7-11(mean,8.7).The guide needle was unadjusted in 3 cases and adjusted for 1-2 times in 4 cases(once in 2 cases and twice in 2 cases).The actual path deviated from the planned by 0.65-1.50 mm(mean,0.98±0.30 mm).The excellent and good rate of screw position was 100%.X-ray and CT examinations were performed at 48 h after the operation.According to the Matta reduction standard,anatomical reduction was achieved in 6 cases and satisfactory reduction in 1 case.All the 7 cases were followed up for 6-28 months(mean,15 months).At the last follow-up,the Harris score of the hip joint was85-96 points(mean,91.6 points)and the pain of visual analogue scale(VAS)was0.There were no complications such as infection,loosening of internal fixation,or neurological dysfunction.Conclusion Anterograde percutaneous screw fixation under robot navigation in the treatment of acetabular anterior column fractures is safe,effective,and satisfactory.

Objective To explore the learning curve of Bikini incision direct anterior approach total hip arthroplasty(Bikini-THA).Methods Clinical data of 80 cases of Bikini-THA initially completed by an operator skilled in posterolateral approach and direct anterior approach total hip arthroplasty from March 2020 to March 2023 were retrospectively analyzed,and the learning curve was observed by scatter plots of operative time and intraoperative bleeding.They were divided into groups A to D according to the order of surgery,with 20 cases in each group.The operative time,intraoperative bleeding,acetabular abduction angle,anteversion angle,angle between stem and femoral axis,postoperative hip Harris score and complications were compared among the 4 groups.Results After about 40 cases,the decreasing trend of operative time and intraoperative bleeding slowed down and stabilized.The operative time and intraoperative bleeding in the 4 groups were group A＞group B＞groups C and D(P＜0.05),and the differences between the group C and group D were not statistically significant(P＞0.05).The acetabular prosthesis was well-positioned in the 4 groups(abduction angle of 30°-50°,anteversion angle of 5°-25°).The femoral prosthesis center fixation rate(angle between stem and femoral axis ≤3°)was group A＜groups C and D(P=0.003,0.003).The differences in the Harris scores of the hip joints at 2 weeks,1 month,3 months,and 12 months postoperatively of the 4 groups were not statistically significant(P＞0.05),and the efficacy evaluations of the hip joints at 12 months postoperatively were all excellent.There were 5 cases of complications in the group A(2 cases of greater trochanter fracture and 3 cases of lateral femoral cutaneous nerve injury),3 cases of complications in the group B(1 case of greater trochanteric fracture,1 case of lateral femoral cutaneous nerve injury,and 1 case of incision infection),1 case of complications in the group C(lateral femoral cutaneous nerve injury),and no complications in the group D.The follow-up period lasted for 12-26 months,with a mean of(19.4±4.7)months.There were no complications such as dislocation or loosening of the prosthesis.Conclusion The Bikini-THA learning curve was approximately 40 cases.

Objective:To evaluate the safety and efficacy of enhanced recovery after surgery(ERAS) in the perioperative period of congenital choledochal cysts in children.Methods:This is a multicenter prospective randomized controlled study. The clinical data of 273 pediatric congenital choledochal cysts(CCC) patients who underwent surgery at 14 medical centers with complete follow-up data were collected through the medical data analysis platform. Among them, 123 cases in ERAS group were managed perioperatively in strict accordance with ERAS mode, and 150 cases in conventional group were managed according to traditional mode. The length of hospital stay,time to first farting, time to complete feeding, the incidence of complications, cost and readmission rate within 30 days,stress indexes and liver function were compared between the two groups.Results:Compared with the conventional group, median time to start farting (2.0 d vs. 3.0 d, P<0.001), median time to complete feeding (5.0 d vs. 7.0 d, P<0.001), median postoperative hospitalization time (6.0 d vs. 9.0 d, P<0.001),the median total length of stay(13.0 d vs. 15.0 d, P<0.001) were shorter,the median hospitalization cost (37,000 yuan vs.43,000 yuan P<0.001) was lower, and stress indexes recovered quickly. The incidence of postoperative hospital stay and readimission rate within 30 d were not statistically different between the two groups. Conclusion:It is safe and feasible to implement ERAS for children with CCC in the perioperative period, which can reduce stress response, speed up recovery,and save medical costs.
