Objective To investigate the effect of bone marrow mesenchymal stem cells(BMSC)transplantation on rats with painful diabetes peripheral neuropathy(PDPN).Methods Fourteen SPF grade male GK rats were randomly divided into model group and treat-ment group,with 7 rats in each group.Seven Wistar rats of the same-sex and same-age were used as the normal group.The treatment group received intraperitoneal injection of BMSC for 6 weeks of treatment.Detection of thermal pain threshold;take the sciatic nerve and observe the pathological morphological changes of the sciatic nerve using hematoxylin-eosin(HE)staining and Masson staining;Western blot was used to detect the expression of JAK2/STAT3 signaling pathway related proteins p-JAK2 and p-STAT3.Results After treat-ment with BMSC,the thermal pain threshold of rats increased slightly;the sciatic nerve injury was repaired,the infiltration of inflammato-ry cells was alleviated,and the phenomenon of demyelination was improved;the expression of pathway related proteins p-JAK2 and p-STAT3 decreased.Conclusion BMSC transplantation can alleviate inflammatory response,repair sciatic nerve,and alleviate pain by in-hibiting the JAK2/STAT3 signaling pathway.

Objective:To explore the nutritional status and quality of life of gastric cancer patients one month after operation in the context of enhanced recovery, and analyze the correlation between them.Methods:From August 2020 to August 2021, 168 patients discharged from the Gastrointestinal Surgery of Ningbo First Hospital after radical resection of gastric cancer were selected as the study subject by convenience sampling. The Nutritional Risking Screening 2002 (NRS2002) and the Global Leadership Initiative on Malnutrition (GLIM) step 2 (excluding muscle mass measurement index) were used to assess the postoperative nutritional status of patients. The quality of life of patients with gastric cancer after operation was investigated with the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30) . Logistic regression analysis was used to explore the influencing factors of nutritional status of postoperative patients with gastric cancer. A total of 168 questionnaires were distributed, and 168 valid questionnaires were recovered, with a valid recovery rate of 100.0%.Results:A total of 104 patients (61.9%) had nutritional risk and 46 patients (27.4%) had malnutrition. There were statistical differences in age, education level, tumor stage, body mass index, physical function, role function, emotional function, cognitive function, general health, fatigue, nausea and vomiting, and loss of appetite among gastric cancer patients with different nutritional status after operation ( P<0.05) . Logistic regression analysis showed that body mass index, physical function, role function, emotional function and fatigue were the influencing factors of the nutritional status of patients one month after operation ( P<0.05) . Conclusions:In the context of enhanced recovery, the nutritional risk and malnutrition rate of gastric cancer patients one month after operation are high, and are closely related to the quality of life. When implementing enhanced recovery after surgery, medical and nursing staff should strengthen and optimize the nutrition management of gastric cancer patients before hospital, during perioperative period and after discharge, improve the nutritional status after operation and the quality of life of patients.

Objective To explore the effect of 12-week simplified Tai Chi training on rehabilitation and neuromuscular control in individuals with chronic ankle instability(CAI).Methods Thirty-four partic-ipants with CAI were randomly divided into an experimental group and a control group,each of 17.The control group received 12-week health education,while the experimental group underwent simpli-fied Tai Chi training for the same length.Before and after the intervention,both groups were evaluat-ed their self-reported instability feeling,ankle muscle strength,proprioception and dynamic postural stability.Results After intervention,a significant increase was observed in the average Cumberland An-kle Instability Tool(CAIT),the maximum extension distance in the posteromedial and posterolateral di-rections of the modified Star Excursion Balance Test(mSEBT)in,as well as the ankle peak torque in plantarflexion,inversion and eversion(P<0.05)in the experimental.Moreover,the ankle passive motion proprioceptive threshold in plantarflexion and inversion decreased significantly in the experimental group after intervention(P<0.05).Meanwhile,after intervention,the average CAIT score,maximum ex-tension distances in the posteromedial and posterolateral directions in the mSEBT,and the ankle peak torques in plantarflexion,inversion and eversion of the experimental group were significantly higher than the control group(P<0.05),while the ankle passive motion proprioceptive threshold in plantarflex-ion was significantly lower than the latter(P<0.05).Conclusion Twelve-week simplified Tai Chi train-ing can improve the clinical subjective instability of CAI participants,maybe related to the improve-ment of ankle muscle strength,proprioception and dynamic postural stability.Therefore,it is suggest-ed that simplified Tai Chi should be one of the rehabilitation methods for CAI patients.

Objective:To construct a cluster care of oral nutrition supplements (ONS) , and to explore its effect in home care of postoperative patients with gastric cancer.Methods:Literature search was conducted to review the status quo of ONS compliance at home in patients with gastric cancer after surgery, and analyze the existing problems. We summarized and formulated the cluster care plan according to the evidence, and established the home ONS management team and process. From November 2020 to October 2021, 107 patients with gastric cancer who needed to implement ONS at home in Gastrointestinal Surgery of Ningbo First Hospital were selected as research objects by convenience sampling. Postoperative patients with gastric cancer from November 2020 to April 2021 were set as the control group ( n=40) , and those from May to October 2021 were set as the observation group ( n=67) . The control group was treated with conventional ONS, and the observation group was treated with home ONS cluster care plan on the basis of the control group. The compliance of nutritional support, weight gain, body mass index increase and follow-up experience between the two groups were evaluated. Results:After six months of intervention, the scores of ONS compliance, weight gain, body mass index increase and follow-up experience in the observation group were significantly higher than those in the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The cluster care plan improves the ONS compliance at home, nutritional status and satisfaction with the follow-up by medical and nursing staff in patients with gastric cancer after surgery, which is worthy of clinical promotion.
