Objective To explore the efficacy of endoscopic minimally invasive release surgery and ultrasound-guided percutaneous needle knife release in treating carpal tunnel syndrome(CTS).Methods A total of 96 patients with CTS,who received treatment at Yixing People's Hospital and Wuxi Ninth Hospital Orthopedic Hospital from January 2021 to December 2024,were selected for this study.Using a random number table method,the 96 patients were divided into an endoscopic group and an ultrasound group,with 48 patients in each group.The patients of endoscopic group received endoscopic minimally invasive release surgery,while the patients of ultrasound group received ultrasound-guided needle knife treatment.The surgical indicators,efficacy,wrist function,median nerve electrophysiological indicators,anatomical indicators,efficacy,and safety were compared between the two groups.Results In the ultrasound group,the surgical duration and postoperative recovery time were shorter than those in the endoscopic group(P＜0.05),and the surgical cost was lower than that in the endoscopic group(P＜0.05).The postoperative Symptom Severity Score(SSS)and Functional Status Scale(FSS)score of both groups were decreased when compared with their preoperative values(P＜0.05),and the SSS and FSS of the ultrasound group were lower than those of the endoscopic group(P＜0.05).After treatment,the resting pain score and activity pain score of both groups were decreased when compared with their preoperative values(P＜0.05),and the resting pain score and activity pain score in the ultrasound group were lower than those in the endoscopic group(P＜0.05).After treatment,both groups showed a reduction in median nerve flattening ratio(FR)and transverse carpal ligament(TCL)thickness when compared with their preoperative values(P＜0.05),and the reduction degree in the ultrasound group was greater than that in the endoscopic group(P＜0.05).After treatment,both groups showed an increase in sensory nerve conduction velocity(SNCV),sensory nerve action potential amplitude(SNAP),and motor nerve action potential amplitude(CMAP)when compared with their preoperative values(P＜0.05),which in the ultrasound group showed a greater improvement than those in the endoscopic group(P＜0.05).The postoperative distal motor latency(DML)was decreased in both groups(P＜0.05),and the DML in the ultrasound group was lower than that in the endoscopic group(P＜0.05).The therapeutic efficacy in the ultrasound group was higher than that in the endoscopic group(P＜0.05).Conclusion Compared to endoscopic minimally invasive release surgery,ultrasound-guided needle knife treatment is more effective in promoting the recovery of wrist joint function in patients with CTS.It can effectively decrease the pain severity of patients,repair anatomical injuries in the wrist,promote the recovery of nerve electrophysiological indicators of the median nerve,with good safety and lower medical costs.

Objective To investigate the relationship between BRCA1 protein expression in lung cancer tissues and the effect of gemcitabine and Cisplatin based chemotherapy.Methods 80 cases of squamous cell carcinoma confirmed by pathology from May 2013 to May 2015 were selected, and treated with gemcitabine plus cisplatin chemotherapy and Ginseng and Astragalus assisted theropy.BRCA1 protein expression of all patients were detected, and relationship between the effect of chemotherapy and prognosis of patients with BRCA1 protein expression in lung cancer tissues were studied.Results In 80 cases, BRCA1 protein was positive in 40 cases, 40 cases were negative, CR 5 patients, PR 6 patients with BRCA1 positive expression, the remission rate was lower than the BRCA1 negative patients ( P <0.05 ) .80 cases of adverse reactions were seen as leukopenia, gastrointestinal symptoms (nausea and vomiting), abnormal liver function, BRCA1 expression of peripheral neurotoxicity, the incidence of complications in patients with positive expression were significantly higher than BRCA1 negative patients(P<0.05).N stage (P=0.03), BRCA1 gene (P=0.02) were independent risk factors of the prognosis of patients.Conclusion BRCA1 protein positive patients in lung cancer tissue had poor chemotherapy effect, more adverse reactions, and poor prognosis.
