Objective To investigate the clinical efficacy of modified arthroscopic revision release for patients who have gluteal muscle contracture and who have poor outcomes after traditional open surgery.Methods The data of patients who underwent modified arthroscopic revision release for residual symptoms of gluteal muscle contracture after traditional open surgery were retrospectively collected and analyzed.All subjects underwent the procedure between December 2015 and December 2022.The surgical efficacy was assessed by evaluating improvements in specific symptoms,including bilateral lower extremity inequality,hip internal rotation and adduction mobility,squatting with both knees pressed together,and the ability to cross one's legs in supine position,as well as the preoperative and postoperative results for the gluteal muscle contracture functionality scale.Paired t-test was performed to examine whether the differences between preoperative and postoperative measurements were statistically significant.Results A total of 36 patients were followed up systematically,with the mean follow-up period being(22.4±4.9)months.All patients had significantly higher scores for assessment with the gluteal muscle contracture functionality scale at the last follow-up than their preoperative assessment results,showing an increase from the preoperative scores of 40.2±5.5 to 78.4±4.9(P＜0.05).At the follow-up,all patients showed improvement in hip adduction and internal rotation mobility compared with their preoperative status and all patients were able to squat with both knees pressed together.Moreover,only 1 patient still had difficulty in crossing his legs.A total of 27 cases(75%)had preoperative leg length inequality,all of which improved to varying degrees at follow-up.Among all the patients(72 hips/cases),8 cases had subcutaneous hematomas and incisional ecchymosis,which were resolved after conservative treatments such as hot compresses.3 cases showed decreased hip abductor strength,but the muscle strength gradually recovered after postoperative exercise and rehabilitation.There were no complications such as subcutaneous exudate,neurovascular injury,or surgical site infection.Conclusion Modified arthroscopic revision release of gluteus muscle contracture is suitable for cases with poor outcomes after conventional open surgery.

Objective To study the effect of scalp acupuncture plus facilitation technique on the temporal and spatial parameters of gait in spastic cerebral palsy. Method Thirty eligible patients with spastic cerebral palsy were randomized into a treatment group and a control group based on the inter-group balance in age, palsy type, and the Gross Motor Function Classification System (GMFCS), 15 cases in each group. The treatment group was intervened by scalp acupuncture, together with the facilitation technique during the retaining of the needles; the control group was also by scalp acupuncture and facilitation techniques but with over 1 h interval between the two methods. The treatment was given once a day, totally for 3 months. The walking, running, and jumping items (E category) of the Gross Motor Function Measure-66 (GMFM-66), temporal and spatial parameters of gait, and vertical ground reaction force during stance were compared before and after the treatment. Result There were no significant inter-group differences in comparing the rates of E category of the GMFM-66 before the treatment (P>0.05), the rates were significantly changed after the treatment in both groups (P<0.05), and there were significant differences in comparing the rates between the two groups after the intervention (P<0.05);after the intervention, the step length, walking speed, and step frequency were increased significantly in both groups (P<0.05), while the double-stance phase was decreased significantly, and swing phase was increased significantly (P<0.05); after the intervention, the step length, walking speed, and step frequency of the treatment group were significantly better than that of the control group (P<0.05). Conclusion Acupuncture plus facilitation technique can mitigate the spasticity in spastic cerebral palsy, improve the gross motor function, especially the function of standing and walking, enhance the activities, and benefit the improvement of the step length, step width, and walk speed.

Catharanthine content and agronomic traits in major Catharanthus roseus varieties were analyzed. It was found that there existed great difference in catharanthine content and agronomic traits among the varieties. Catharanthine content was the highest in variety Pacifica Polka Dot (PPD), reaching 3.79 mg g(-1) dry leaf weight, and the lowest in variety Cooler Pink (CP) with only 0.9 mg g(-1) dry leaf weight. Correlation existed in certain extent between catharanthine content and agronomic traits in C. roseus. Path analysis showed that among all the agronomic traits analyzed, internodal distance positively affected catharanthine content at significant level (P<0.05), with the path coefficient being 1.473. This study provides useful information for high-catharanthine content C. roseus introduction and breeding.
