Objective To summarize the clinical features,diagnosis and treatment and prognosis of trocar site hernia(TSH).Methods Clinical data of 12 patients with TSH receiving laparoscopic surgery from January 2019 to January 2023 were retrospectively analyzed.The clinical manifestations included intestinal obstruction in 8 cases,trocar incision prolongation with fluid seepage in 1 case,and no obvious symptoms in 3 cases.The patients were diagnosed by abdominal CT in 9 cases,by small intestine contrast imaging in 1 case,by abdominal MRI in 1 case,and by abdominal plain film combined with abdominal color ultrasound in 1 case.The hernia was located in the right lower abdomen in 5 cases,the left lower abdomen in 4 cases,and the right upper abdomen in 3 cases.The trocar diameter was 12 mm in 6 cases,10 mm in 5 cases,and 5 mm in 1 case.A drainage tube was placed at trocar site in 5 cases.Open operations were performed in 11 cases,including small intestine reduction and abdominal wall layer-by-layer suture in 4 cases,partial small intestine resection and anastomosis in 3 cases,Onlay repair in 3 cases,and partial omentectomy,transverse colon reduction and Onlay repair in 1 case.Another case developed trocar site refractoriness which did not heal,and the patient refused surgery,who was given dynamic observation.Results The operation was successful in the 11 cases.Postoperatively,1 case of inflammatory intestinal obstruction underwent intestinal decompression tube implantation,1 case of incision bleeding underwent emergency operation again to stop bleeding,and the rest recovered smoothly.All the 12 patients were followed up for 5-48 months,with a median of 13 months.The patient without surgery had persistent induration and intermittent exudation at the trocar site.One case died due to tumor metastasis,and none of the others had hernia recurrence.Conclusions The most common manifestation of TSH is intestinal obstruction,which mostly occurs at trocar with diameter≥10 mm.If there are symptoms,it should be treated by surgery as soon as possible.

Post-intensive care syndrome (PICS) is the most common complication in patients discharged from intensive care unit (ICU), which seriously affects the life quality of the patients. At present, there is still lack of standardevaluation methods for PICS. Continuous and dynamic assessment can earlyidentify PICS, moreover, early identification and intervention of PICS can improve the life quality of patients those patients, which is critical to improve the long-term outcome of the patients. In this paper, we reviewed the current research states of evaluation timing, contents, tools and modalities of PICS domestic and abroad, analyzed the problems and prospects of the existing evaluation methods, aiming to provide a reference for clinical staff to effectively and comprehensively evaluate PICS.

Objective To study the effects of thymus transplantation(TT)combined with CD4--DLI on T cell reconstitution after allogeneic hematopoietic stem cell transplantation(allo-HSCT). Methods BALB/c mice were randomly divided into three groups:hematopoietic stem cell transplantation (HSCT group),hematopoietic stem cell transplantation combined with thymus transplantation(TT group)and hematopoietic stem cell transplanta-tion combined with thymus transplantation plus CD4+ T cell-depleted lymphocyte infusion(CD4--DLI group). On day-1,the mice were treated with the lethal dose of radiotherapy. On day 0,C57BL/6 mice were used as donor for hematopoietic stem cell transplantation. The mice were sacrificed on 5 days,2 weeks,4 weeks and 3 months after transplantation,respectively. The peripheral blood and spleen cells of mice were collected for determinations of T cell surface antigen,T cell receptor,naive T cells and intracellular cytokines. HE staining was used to assess the development of donor thymus. Results TT and CD4--DLI did not impair each other′s effects on T cell reconstitu-tion. TT combined with CD4--DLI increased the number of T cell reconstruction. CD4--DLI promoted the effect of TT on enlargement naive CD4+and CD8+T cell pool. Combination of TT and CD4--DLI enhanced the cytokine pro-duction of T cells. Conclusion TT combined with CD4--DLI had no side effects on TCR repertoire and thymus. Conclusion TT combined with CD4--DLI can enhance the reconstitution of T cell number and function via thymus dependent and thymus independent mechanism.
