Objective To explore the effect of perioperative nutritional support chain management on the postoperative nutritional status and nutrition knowledge-attitude-practice level of patients with gastric cancer. Methods A total of 162 gastric cancer patients were divided into control group with 82 cases (admitted from June to December 2021) and intervention group with 80 cases (admitted from January to June 2022) according to their admission time. The control group received routine perioperative nutritional management, while the intervention group received nutritional support chain management. The nutritional status and nutrition knowledge-attitude-practice level were compared between the two groups at one month after surgery. Results The proportion of patients with total protein < 60 g/L in the intervention group at one month after surgery was 5.00%, which was lower than 14.63% in the control group; the proportion of patients with albumin < 35 g/L in the intervention group at one month after surgery was 3.75%, which was lower than 13.41% in the control group; the proportion of patients with normal body mass index (BMI) in the intervention group at one month after surgery was 83.75%, which was significantly higher than 59.75% in the control group (P < 0.05). The scores of nutrition knowledge, support attitude and support behavior as well as the total nutrition knowledge-attitude-practice score in the intervention group at one month after surgery were significantly higher than those in the control group (P < 0.05). Conclusion Implementation of perioperative nutritional support chain management can effectively increase the patient's nutrition intake, improve the postoperative nutritional status of gastric cancer patients, and enhance their nutrition knowledge-attitude-practice level and quality of life.

Objective To investigate the effect of mesenchymal stem cells(MSCs)combined with immunosuppressants(IS)on immune rejection in a rat model of liver transplantation.Methods F344 rats were divided into Normal group(without any intervention),PS group(injected with an equal volume of normal saline),MSC group(injected with MSC),IS group(injected with IS),and MSC+IS group(injected with MSC and IS),with 8 rats in each group.For all rats except those in the Normal group,the Kamada's double-cuff method was used to establish a model of orthotopic liver transplantation,without reconstruction of the hepatic artery.HE staining and Masson staining were performed for rat liver tissue,and the degree of liver fibrosis was analyzed;immunohistochemical experiments were used to measure the infiltration of T cells and NK cells,and immunofluorescence assay was used to analyze macrophage M2 polarization.A one-way analysis of variance was used for comparison of continuous data between multiple groups,and the least significant difference t-test was used for further comparison between two groups.The Kaplan-Meier method was used to plot survival curves,and the log-rank test was used for survival analysis.Results Compared with the PS group,the MSC+IS group had a significantly prolonged survival time(P＜0.01),and the MSC group,the IS group,and the MSC+IS group had a significant improvement in the histological structure of the liver and a significant reduction in the degree of liver fibrosis(all P＜0.000 1),as well as a significant reduction in the infiltration of NK and T cells(all P＜0.000 1)and a significant increase in the degree of macrophage M2 polarization(all P＜0.000 1).The MSC+IS group had a significantly better effect than the MSC group and the IS group.Conclusion MSCs combined with IS can improve liver histopathology,reduce inflammatory cell infiltration,promote macrophage M2 polarization,and exert an immunosuppressive effect in rats after liver transplantation.

Objective:To observe the effect of Wenyang Huazhuo recipe (WYHZ) on pregnancy outcomes in patients with unexplained recurrent spontaneous abortion (URSA).Methods:A retrospective cohort study was used and 240 cases of pregnancy URSA patients with spleen kidney yang deficiency syndrome at the Reproductive Center, First Teaching Hospital of Tianjin University of Traditional Chinese Medicine and Department of Gynaecology and Obstetrics, General Hospital of Tianjin Medial University from November 2018 to March 2022 were recruited. The patients were assigned to WYHZ group (120 cases) and control group (120 cases) based on whether accepting oral WYHZ from 3 months before pregnancy to 8-12 weeks after pregnancy regularly. Pregnancy outcomes, perinatal period outcomes and obstetric complications were compared between the two groups. Multivariate logistic regression were used to analyze the effect of WYHZ on pregnancy outcome.Results:The live birth rate and the clinical pregnancy rate in WYHZ group [86.67% (104/120), 90.00% (108/120)] were higher than those in control group [71.67% (86/120), P=0.004; 75.00% (90/120), P=0.002]. The early abortion rate in WYHZ group [10.08% (12/119)] was lower than that in control group [25.86% (30/116), P=0.002], the differences were statistically significant. There were no significant differences in perinatal outcome and incidence rate of obstetric complications between the two groups (all P>0.05). Multivariate logistic regression analysis showed that the application of WYHZ significantly improved the live birth rate ( OR=8.818, 95% CI: 3.556-21.871, P<0.001) and sustained pregnancy rate ( OR=11.261, 95% CI: 4.262-29.751, P<0.001) in URSA patients. Conclusion:WYHZ using before and during pregnancy can significantly improve the live birth rate and the clinical pregnancy rate of URSA patients with syndrome of yang deficiency of spleen and kidney, and improve their pregnancy outcomes.

Objective To evaluate the effect of neoadjuvant chemotherapy by different arteriovenous ways on ovarian function of patients with locally advanced cervical cancer after surgery. Methods We retrospectively studied 38 cases of young women (surgical age <45 years) who were diagnosed with locally advanced squamous cell carcinoma of the cervix and undergone radical hysterectomy with ovaries. According to the way of adjuvant chemotherapy, these cases were divided into 20 cases of group A (arterial embolization chemotherapy), 18 cases of group B (intravenous chemotherapy). Each patient underwent a course of chemotherapy. Then we retrospectively analyzed and compared serum estradiol (E2 ), follicle stimulating hormone (FSH), lute-inizing hormone (LH) in two groups before and after surgery to assess ovarian function. We compared E2 ,FSH and LH levels 2-3 weeks after chemotherapy (before surgery) and 1 month after surgery,and 6 months after surgery in two groups. Results The E2 levels in group A 1 month before and after surgery significantly decreased, while FSH increased compared with those be-fore chemotherapy(P<0. 05). LH levels in two groups at different time points and 6 months after surgery showed no significant difference (P>0. 05) compared with those before chemotherapy. the E2 , FSH and LH levels in group B at different time points presented no significant difference (P>0. 05). Only E2 level in group A was significantly lower than that in group B before surger-y. Conclusion For patients with locally advanced cervical cancer, the effect of arterial embolization chemotherapy before sur-gical intervention on ovarian function is transient and reversible, while intravenous chemotherapy before surgery exerts few effects on ovarian function. Retaining ovaries in radical hysterectomy is a safe and effective method to protect the endocrine function for young patients with locally advanced cervical cancer.
