Objective A scoping review was conducted on relevant studies regarding the use of non-invasive brain-computer interface(BCI)technology to promote the rehabilitation of upper limb function in stroke patients,aiming to provide new ideas and references for the rehabilitation nursing of stroke patients.Methods Relevant studies on non-invasive BCI in upper limb functional rehabilitation of stroke patients were searched through computer system including Chinese biomedical literature database,Wanfang database,CNKI,VIP database,Cochrane Library,PubMed,Embase and Web of Science.The search period was from the establishment of the database to December 6,2024,and the included literature was sorted and analyzed.Results A total of 23 articles were included,involving 1 235 stroke patients.Non-invasive brain-computer interface technology mainly includes brain-computer interface based on motion imagination combined with virtual reality technology,functional electrical stimulation and exoskeleton robot.The main evaluation indexes were Fugl-Meyer upper extremity partial scale,modified Barthel index,event related desynchronization intensity,upper limb motor function rating scale,etc.Non-invasive brain-computer interface technology can improve upper limb function,self-care ability and stimulation of cerebral cortex in stroke patients.Conclusion Non-invasive brain-computer interface technology is feasible and effective in upper limb functional rehabilitation training of stroke patients,but there are few relevant studies.In the future,a new era multidisciplinary rehabilitation model can be built,and scientific and practical evaluation indicators were formulated to promote rapid rehabilitation of stroke patients.

Objective To compare the clinical effect of neoadjuvant chemoradiotherapy (nCRT) and neoadjuvant chemotherapy (nCT) in the treatment of locally advanced esophageal squamous cell carcinoma.Methods The retrospective cohort study was conducted.The clinicopathological data of 156 patients with local advanced esophageal squamous cell carcinoma who were admitted to the Zhongshan Hospital of Fudan University from January 1,2010 to December 31,2015 were collected.Among 156 patients,59 undergoing nCRT were allocated into the nCRT group and 97 undergoing nCT were allocated into the nCT group.Patients in the nCRT group and nCT group respectively received 2 cycles chemotherapy by the TP regimen+40 Gy radiotherapy (2 Gy/d) and 2 cycles chemotherapy by the TP regimen.Patients were evaluated by imaging examinations after 6 weeks neoadjuvant therapy completion,and then underwent abdominal and right chest-left cervico three-incision thoracoscopic surgery.Observation indicators:(1) treatment situations;(2) postoperative pathological examination;(3) follow-up and survival situations.Follow-up using outpatient examination and telephone interview was performed once every 3 months within 2 years and once every 6 months after 3 years up to January 2017.Follow-up included levels of tumor markers [carcinoembryonic antigen (CEA) and SCC-Ag],thoracic or abdominal computed tomography (CT),neck and abdominal ultrasonography and gastroscopy or PET/CT examination if necessary.Measurement data with normal distribution were represented as (x)±s and comparison between groups was analyzed using the t test.Measurement data with skewed distribution were described as M (range) and comparison between groups was analyzed using the nonparametric test.Count data were analyzed using the chi-square test or Fisher exact probability.Comparison of ordinal data was done by the nonparametric test.The survival rate was calculated using the life table method and survival was analyzed by the Log-rank test.Results (1) Treatment situations:all the patients in the 2 groups were able to burden neoadjuvant therapy and thoracic esophagectomy.Six patients in the nCRT group and 15 in the nCT group had conversion to open surgery.Operation time,volume of intraoperative blood loss,cases with postoperative readmission of ICU,cases with complications,cases with perioperative death and duration of hospital stay were (201 ± 25) minutes,(137± 66)mL,5,24 (10 with pulmonary complications,8 with anastomotic leakage,3 with hoarseness,2 with cardiovascular complications and 1 with chylopleura),0,12 days (range,9-93 days) in the nCRT group and (195±20) minutes,(133±58) mL,8,30 (11 with anastomotic leakage,10 with pulmonmy complications,4 with hoarseness,2 with cardiovascular complications,1 with postoperative hemorrhage,1 with delayed gastric emptying and 1 with chylopleura),1,11 days (range,9-78 days) in the nCT group,respectively,with no statistically significant difference between the 2 groups (x2 =0.883,t =0.102,0.692,x2 =0.048,1.541,Z =0.225,P＞ 0.05).(2) Postoperative pathological examination:R0 resection rate was 96.6％ in the nCRT group and 93.8％ in the nCT group,with no statistically significant difference between the 2 groups (x2 =0.589,P＞0.05).Results of postoperative pathological examination showed that G0,G1,G2 and G3 of tumor regression grade were respectively detected in 18,16,7,18 patients in the nCRT group and 4,5,4,84 patients in the nCT group,with a statistically significant difference between the 2 groups (Z=-7.151,P＜0.05).Stage 0,Ⅰ,Ⅱ,ⅢA,Ⅲ B and ⅣA of postoperative ypTNM stage were respectively detected in 16,9,23,4,6,1 patients in the nCRT group and 4,9,37,6,34,7 in the nCT group,with a statistically significant difference between the 2 groups (Z=-4.890,P＜0.05).The down-staging was detected in 48 patients of the nCRT group and 50 patients of the nCT group,with a statistically significant difference between the 2 groups (x2=13.957,P＜0.05).(3) Follow-up and survival situations:of 156 patients,153 were followed up for 12-82 months,with a median time of 36 months.The 1-,3-,5-year overall survival rates were 88.1％,61.4％,34.9％ in the nCRT group and 81.4％,43.8％,23.1％ in the nCT group,with a statistically significant difference between the 2 groups (x2=4.336,P＜0.05).Conclusion The nCRT in the treatment of locally advanced esophageal squamous cell carcinoma can enhance postoperative pathological response rate,down-staging rate and overall survival rate compared with nCT,without increasing incidence of perioperative complications.

[ ABSTRACT] AIM:To investigate the effect of Jia-jian-yi-yin decoction on endothelium-dysfunction in ovariecto-mized rats.METHODS:The ovariectomized rats were treated with Jia-jian-yi-yin decoction or turbid liquid of estradiol va-lerate for 8 weeks.The vascular ring tension was measured.Scanning electron microscopy and Western blotting were ap-plied to assess the function of endothelium-dependent dilation, aortic endothelial morphology and the expression of endothe-lial lipase.The pathologic sections were prepared to observe the effect of Jia-jian-yi-yin decoction on the uterus.RE-SULTS:In ovariectomized rats, the decrease in endothelium-dependent relaxation to acetylcholine ( ACh) was reversed to normal level, the endothelial morphology returned to normal without lipid accumulation and the endothelial lipase expression was decreased by Jia-jian-yi-yin decoction.Furthermore, no obvious change of the wet weight of uterine between the ovari-ectomized rats with or without Jia-jian-yi-yin decoction treatment was observed.CONCLUSION:Jia-jian-yi-yin decoction may have protective effects on endothelium-dependent vasodilation and aortic endothelial morphology in estrogen-deficient animals.
