Objective:To develop the rehabilitation needs questionnaire for stroke patients, so as to provide a tool for medical staff to implement continuous rehabilitation services.Methods:Based on the conceptual framework of the International Classification of Function, Disability and Health, and on the basis of literature review and qualitative research, the questionnaire items were preliminatively established after two rounds of Delphi expert consultation, and 130 stroke patients admitted to the Department of Neurology and Rehabilitation of the First Hospital of Shanxi Medical University from April to December 2021 were selected to test the reliability and validity of the questionnaire. And 200 stroke patients were selected for confirmatory factor analysis to form a formal scale.Results:Exploratory factor analysis extracted a total of 4 common factors: physiological function rehabilitation needs, social rehabilitation environmental support needs, emotional/psychological support needs, rehabilitation knowledge/information needs. After project analysis and 3 exploratory factor analysis, a final questionnaire containing 16 items was formed.The Cronbach α of the questionnaire was 0.935, with a broken half reliability of 0.824. The fitting index of confirmatory factor analysis was within the standard range. The χ2/ df was 2.979, the incremental fitting index was 0.907, the comparative fitting index was 0.906, and the root mean square error of approximation was 0.100. Conclusions:The reliability and validity of the rehabilitation needs questionnaire for stroke patients are good, which can preliminarily assess the rehabilitation needs of stroke patients.

Objective::To build a reference fetal growth chart for the Chinese population based on fetal ultrasound measurements.Methods::This was a multicenter, population-based retrospective cohort study. Longitudinal ultrasound measurement data were collected from 24 hospitals in 18 provinces of China from 1 st September through 31 st October of 2019. The estimated fetal weight (EFW) was calculated based on head circumference, abdominal circumference, and femur length using Hadlock formula 3. Fetal growth curves were estimated using a two-level linear regression model with cubic splines. All participants were divided into two groups: the northern group ( n = 5829) and the southern group ( n = 3246) based on the geographical division of China and male fetus group ( n = 4775) and female fetus group ( n = 4300) based on fetal gender. The EFW was compared by fetal gender and geographical group. All statistical models were adjusted for maternal sociodemographic characteristics. Results::A total of 9075 participants with 31,700 ultrasound measurement records were included in this study. Male fetuses demonstrated significantly larger EFW compared to female ones starting at 16 weeks of gestation and extending to delivery (global test P < 0.01). The overall geographic difference in EFW was significant (global test P = 0.03), and week-specific comparisons showed that the northern group had a greater EFW starting at 15 weeks of gestation and extending to 29 weeks of gestation, although this difference did not extend to the time of delivery. The Z-score of EFW confirmed that our Chinese fetal growth charts differed from previously published standards. Conclusion::This study provides EFW and ultrasound biometric reference measurements for Chinese fetuses and reveals differences from other fetal growth charts. The chart is worth promoting in more regions of China but should be tested prudently before use.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder, and its prevalence has been increasing during the recent years, which has posed a great impact on the families of the patients and society. Epidemiological studies have found that environmental exposure factors have an important impact on the occurrence and development of ASD, including pesticides, heavy metals, poly- and perfluoroalkyl substances, phenols, and air pollution. This paper focused on the relationship between environmental exposure to the above mentioned typical environmental exposure factors and the occurrence of ASD, in order to provide reference for related research of ASD.

Objective: To investigate the clinical outcomes and radiological results of arthroscopic autologous scapular spine bone graft transplant to treat shoulder recurrent instability. Methods: Data of 27 patients diagnosed as shoulder recurrent instability with the bone defect of 10%-15% from July 2016 to August 2018 who were treated by arthroscopic autologous scapular spine bone graft transplant were retrospectively analyzed. There were 20 males and 7 females with an average age of 30.8 years old (range, 19-50). The bone loss of the glenoid was 10%-15%. The time between the first dislocation and the surgery was 24.1±15.8 months. The patients were treated with arthroscopic autologous scapular spine bone graft transplant. Postoperatively the affected shoulder was immobilized by the abduction brace for 6 weeks, after that the passive motion was applied. Strengthening exercise began at 10-12 weeks and sports was allowed after 6 months. Constant-Murley score and the Disabilities of Arm, Shoulder and Hand (DASH) score were used to evaluate the shoulder function, and visual analogue score (VAS) score was used to evaluate the degree of pain. Computed tomography scans were obtained one week post-operation and at the latest follow-up, from which the length, width, height and volume of the bone graft were measured and the absorption rate of the bone graft was calculated. The subjective satisfaction degree of patients at the latest follow-up was also recorded. Results: All 27 patients were followed up for 19.8 months (range, 13-39 months). No infection or neurovascular injury was identified. At the latest follow-up, the Constant-Murley score was 85.15±5.62 (range, 76-94), the DASH score 13.39±5.51 (range, 3.19-21.95) and the VAS score 1.29±0.45 (range, 1-2), thus all of those were improved significantly compared to those of pre-operation. At the latest follow-up, the anterior flexion was 153°±24°, lateral rotation by side 38°±21°, internal rotation 70°±21°, and abduction was 139°±18°. At the latest follow-up, the absorption rate of the bone graft was 46.1%±20.6% (range, 24.0%-71.7%). Among all the 27 patients, 19 patients considered the outcome as very good, and 6 patients considered as good, 2 patients fair. Conclusion Arthroscopic autologous scapular spine bone graft transplant could successfully treat shoulder recurrent instability with glenoid bone loss at 10%-15%. This technique could achieve satisfactory clinical results, improve glenohumeral stability, decrease the re-dislocation rate.

Objective To evaluate the clinical and radiological results of Phlios plate and Multiloc nail in treatment of proximal humerus fractures.Methods From February 2013 to December 2015,data of 37 cases of proximal humerus fractures who were treated by reduction and fixation using Phlios plate or Multiloc nail were retrospectively analyzed.In group one (Phlios plate),there were 10 males and 8 females,with an average age of 56.3±5.8 years,including 7 cases of Neer 2-part surgical neck fracture,6 cases of Neer 3-part fracture,4 cases of Neer 4-part fracture,and 1 case of fracture-dislocation.In group two (Multiloc nail),there were 8 males and 11 females,with an average age of 57.2±7.4 years,including 8 cases of Neer 2-part surgical neck fracture,9 cases of Neer 3-part fracture,1 case of Neer 4-part fracture,and 1 case of fracture-dislocation.Operation time,range of motion of shoulder joint,visual analogue scale (VAS) pain score,American Shoulder & Elbow Surgeon (ASES) score and ConstantMurley score were collected.Results All 37 patients were followed up for an average period of 15.5 months (range,12-36 months).The average bone healing time were 2.5±0.5 months (range,2-3 months)and 2.2±0.5 months (range,1.5-3 months) in the plate and nail group respectively.At the latest follow-up,average VAS score was 0.4±0.6 (range,0-2),the ASES score aver aged 85.4±6.8 points (range,73-96),Constant-Murley score averaged 83.4±7.3 points (range,71-94),and external rotation averaged 30.8°±10.0° (range,10°-50°) in plate group,while average VAS score was 0.2±0.4 (range,0-1),ASES score averaged 89.7± 5.6 points (range,80-98),Constant-Murley score averaged 88.5±6.8 points (range,76-98),and external rotation averaged 40.3°± 7.9° (range,20°-50°) in the intramedullary nailing group.One case had partial necrosis of humeral head in the plate group,while 1 case suffered absorption of the greater tuberosity in the nail group,with the complication rate of 5.6％ (1/18) and 5.3％ (1/19) respectively,without significant difference.The internal and external rotation degrees,ASES and Constant-Murley scores were better in nail group than those in plate group for 2-part fractures,while the forward elevation and abduction degrees were similar.Conclusion Similar results were achieved for the treatment of proximal humeral fractures by Phlios plate and Multiloc nail.The Multiloc nailing group had achieved superior outcomes in Neer-2-part proximal humeral fractures.

Objective To compare the efficacy of endovascular interventional treatment and surgical clipping in posterior communicating artery aneurysm (PCoAA) patients with fetal-type posterior cerebral artery (fPCA).Methods The PCoAA patients with fPCA were enrolled.Their baseline clinical data were collected.The modified Rankin Scale (mRS) was used to assess the clinical outcomes at six months after procedure.The mRS score 0-2 was defined as good outcome.Results A total of 35 PCoAA patients with fPCA were enrolled into the study,23 were treated with interventional embolization therapy and 12 were treated with craniotomy clipping.There were no significant differences in age,gender,preoperative Fisher grade,Hunt-Hess grade,baseline GCS scores,and aneurysm typing between the 2 groups.The good outcome rate of the interventional embolization group at 6 months was higher than that of the surgical clipping group,but there was no significant difference (65.22％ vs.41.67％;P =0.282).Results The efficacy of PCoAA using interventional embolization therapy combined fPCA is almost the same as craniotomy clipping.
