Chinese Journal of Orthopaedics 2001;0(01):-
Objective To evaluate the effects of transplant adductor brevis and gracilis to correct scissors gait in spastic cerebral palsy. Methods From July 2000 to December 2004, 73 patients with scissors gait of spastic cerebral palsy were treated with transplantation of adductor brevis and gracilis, 47 were males and 26 were females, with the average of 12.06 years old. According to Ashworth's standard, the muscle tension was evaluated before surgery. 12 cases were in degree Ⅰ, 38 cases were in degreeⅡ, 18 cases in degree Ⅲ and 5 cases in degree Ⅳ. The end of adductor brevis was cut off and sutured with tensor fasciae latae through the tunnel under the skin, the end of gracilis was cut off and transplanted to the lateral condylus of femur through the back of the knee. Some certain surgery completed at the same time, the semitendious and biceops muscle was transplanted to the front of the knee(37 cases) and extended(13 cases), the soft tissue was released in hip joint(55 cases), the gastrocnemius cut off (32 cases), the Achilles's tendon extended(30 cases) and tibialis anterior lateral transplantation (31 cases), only peroneus longus lateral transplantation (8 cases). After operation the lower limbs was fixed with plaster cast for 6 weeks, then the plaster cast was removedassociating with functional exercise. The orthopaedic results were evaluated on the function of hip, knee, foot-malleoious and the gait, then classified four grades. Results All patients were followed up an average of 24.4 months. The scissors gait was corrected completely, 61 cases were excellent, 10 cases were good, 2 cases were fair. The majority symptom of whem was the knee flexure, but can be relieved by medicine. There were significant differences compared pre-operation with post-operation in four groups, and also between degree Ⅳ group and degree Ⅰand Ⅱgroup(P

Objective:
To evaluate the clinical application of bronchial washing fluid (BWF) in the detection of epidermal growth factor receptor (EGFR) gene mutation in lung cancer patients during diagnostic bronchoscopic procedure.
Methods:
Patients with suspected lung cancer lesions but failed to be identified as malignancy by rapid on-site cytologic evaluation (ROSE) were enrolled. Performed blocker PCR for EGFR mutation detection using the supernatant and cell pellet of BWF samples and compared the detective results to the EGFR mutation status detected using histologic tumor samples.
Results:
A total of 85 BWF and paired histological samples were collected at Fudan University Affiliated Zhongshan Hospital from October 2016 to June 2017. There were 46 male and 39 female, with a mean age of 61 years (range 30-87 years). Thirty-one patients had benign diseases and 54 patients had primary lung cancer. Among these 54 lung cancer patients, the diagnoses were made basing on bronchoscopic biopsy samples in 31 patients. The detection rate of EGFR gene mutation in BWF samples was 100.0% concordant with that using histological samples.Another 23 cases whose bronchoscopic biopsy failed to establish malignant diagnoses were further identified by other sampling methods including surgical resection, lung biopsy, etc. A total of 15 patients were identified as EGFR mutated type by pathologic detection or clinically effect assessment, and BWF could detect 11 of them, accounting for 11/15 of all cases. Overall, BWF had achieved an overall accuracy of 95.3% (81/85) comparing to paired tumor histologic samples.
Conclusions
BWF is an effective complementary specimen to bronchoscopic biopsy samples in EGFR gene mutation detection in patients with suspected lung cancer lesion and negative biopsy results evaluated by ROSE during bronchoscopy.

Objective:To investigate the clinical outcome of arthroscopic suture-button Bristow procedure using suture-button fixation for treatment of recurrent anterior shoulder instability.Methods:A retrospective case series study was conducted to analyze 28 patients with recurrent anterior shoulder instability admitted to Shanghai Sixth People’s Hospital from March 2015 to September 2018,including 26 males and 2 females,aged 18-36 years [(24.1 ± 3.2)years]. Preoperative MRI showed Bankart injury and three-dimensional CT showed glenoid bone defect > 15%. The Hill-Sachs injury was found in 27 patients. Arthroscopic Bristow procedure was used to fix coracoid process graft with the suture-button plate and glenoid labial complex was repaired with the suture anchor to treat anterior instability of the shoulder joint. The visual analogue scale (VAS),American shoulder and elbow surgeon (ASES) scale,Constant score and Rowe score were used to evaluate the shoulder joint function preoperatively,at postoperative 3,6,12 months and at the last follow-up. The postoperative infection,neurovascular injury,redislocation and other complications were recorded,and the incidence rate was calculated. The bone resorption and bone healing of coracoid process graft were analyzed by CT.Results:All patients were followed up for 22 - 36 months [(24.5 ± 6.3) months]. Three months after operation,the VAS,ASES scale and Constant score were not significantly different from those before operation ( P > 0.05). In comparison,the Rowe score was significantly higher than that before operation ( P < 0.05). Six and twelve months after operation,the VAS,ASES scale,Constant score and Rowe score were significantly improved from those before operation ( P < 0.05). At the last follow-up,the VAS decreased from (2.7 ± 1.5)points preoperatively to (0.8 ± 0.3)points,the ASES scale increased from (78.6 ± 12.7)points preoperatively to (92.4 ± 8.4)points,the Constant score increased from (43.4 ± 5.2) points preoperatively to (81.6 ± 6.7) points,the Rowe score increased from (52.3 ± 7.1)preoperatively to (92.7 ± 5.4) points ( P < 0.05). During the follow-up,there was no infection,neurovascular injury,re-dislocation and other complications. In addition,24 (86%) out of the 28 patient showed healing of coracoid process grafts,and the overall bone resorption rate was (18.4 ± 6.1)%. No patients had glenohumeral joint osteoarthritis. Conclusion:Arthroscopic Bristow procedure using suture-button fixation for treatment of recurrent anterior shoulder instability has advantages of a low rate of postoperative complications and a high union rate,indicating an effective and safe surgical procedure.

Purpose:
Loss-of-function mutations in the adenomatous polyposis coli (APC) gene are common in metastatic colorectal cancer (mCRC). However, the characteristic of APC specific mutations in mCRC is poorly understood. Here, we explored the clinical and molecular characteristics of N-terminal and C-terminal side APC mutations in Chinese patients with mCRC.
Materials and Methods:
Hybrid capture-based next-generation sequencing was performed on tumor tissues from 275 mCRC pati-ents to detect mutations in 639 tumor-associated genes. The prognostic value and gene-pathway difference between APC specific mutations in mCRC patients were analyzed.
Results:
APC mutations were highly clustered, accounting for 73% of all mCRC patients, and most of them were truncating mutations. The tumor mutation burden of the N-terminal side APC mutations group (n=76) was significantly lower than that of the C-terminal side group (n=123) (p < 0.001), further confirmed by the public database. Survival analysis showed that mCRC patients with N-terminus side APC mutations had longer overall survival than C-terminus side. Tumor gene pathway analysis showed that gene mutations in the RTK/RAS, Wnt and transforming growth factor β signaling pathways of the C-terminal group were significantly higher than those of the N-terminal group (p < 0.05). Additionally, KRAS, AMER1, TGFBR2, and ARID1A driver mutations were more common in patients with C-terminal side APC mutations.
Conclusion
APC specific mutations have potential function as mCRC prognostic biomarkers. There are obvious differences in the gene mutation patterns between the C-terminus and N-terminus APC mutations group, which may have certain guiding significance for the subsequent precise treatment of mCRC.
