Objective:To compare the clinical efficacy of laparoscopic pelvic floor autologous fascia integral repair based on membrane anatomy versus transperineal proctosigmoidectomy (Altemeier procedure) in the treatment of patients with complete rectal prolapse (CRP).Methods:This study employed a retrospective observational cohort design. Clinical data were collected from a total of 55 CRP patients who underwent surgical treatment between January 2018 and July 2023, including 25 patients from Luoyang Central Hospital, affiliated with Zhengzhou University, and 30 patients from the 989th Hospital of the Joint Logistics Support Force & Military Anorectal Surgery Research Institute. All patients undergoing surgery met the following criteria: aged ≥ 18 years, rectal prolapse protruding outside the anus, prolapse length > 5 cm with inability to self-reduce, conforming to the diagnostic criteria for CRP, and being first-time treated patients. Twenty-seven patients who underwent the Altemeier procedure between January 2018 and March 2021 were assigned to the Altemeier group; 28 patients who underwent laparoscopic pelvic floor autologous fascia integral repair based on membrane anatomy between April 2021 and July 2023 were assigned to the integral repair group. The therapeutic efficacy differences between the two groups were analyzed and compared, including the CRP length (DCRP), Wexner Constipation Score, Wexner Fecal Incontinence Score, and Gastrointestinal Quality of Life Index (GIQLI) before surgery and at 6, 12, and 24 months after surgery, as well as postoperative complications and recurrence at 24 months after surgery.Results:There were no statistically significant differences between the two groups in terms of gender distribution, age, preoperative body mass index (BMI), defecation frequency, DCRP, Wexner Constipation Score, Wexner Fecal Incontinence Score, and GIQLI (all P>0.05). All patients completed the surgery. The length of hospital stay and intraoperative blood loss in the integral repair group were significantly less than those in the Altemeier group (both P<0.01). At 6, 12, and 24 months after surgery, the DCRP, Wexner Constipation Score, Wexner Fecal Incontinence Score, and GIQLI in both groups significantly improved compared with the preoperative values (all P<0.001). At 6, 12, and 24 months after surgery, the CRP treatment effect, Wexner Constipation Score, Wexner Fecal Incontinence Score, and GIQLI in the integral repair group were significantly better than those in the Altemeier group (χ2=15.821, P<0.001; χ2=18.238, P<0.001; χ2 = 12.558, P=0.001; and χ2 =22.413, P<0.001, respectively). In the integral repair group, 4 patients (14.3%) developed grade I-III postoperative complications, including 2 cases of urinary retention, 1 case of anastomotic bleeding, and 1 case of anastomotic stenosis. In the Altemeier group, 11 patients (40.7%) developed grade I-III postoperative complications, including 4 cases of urinary retention, 3 cases of anastomotic bleeding, 1 case of anastomotic stenosis, 2 cases of intestinal fistula, and 1 case of fecal incontinence. The difference between the two groups was statistically significant (χ2=4.850, P=0.028). There was no recurrence of CRP in the integral repair group at 24 months after surgery, while 7 cases of CRP recurrence were observed in the Altemeier group at 24 months after surgery. The difference between the two groups was statistically significant (χ2=6.148, P=0.013). Conclusion:The autologous fascia repair technique based on membrane anatomy and the pelvic floor integral theory is superior to the transperineal Altemeier procedure in the treatment of CRP. Furthermore, it is an effective surgical method for CRP.

BACKGROUND:Decreased function and reduced number of CD4+CD25+regulatory T cells have been considered the major manifestation of immunity dysfunction in children with primary nephrotic syndrome. Bone marrow mesenchymal stem cells have immunoregulation effects, which up-regulate CD4+CD25+regulatory T cells, inhibit proliferation of lymphocytes, and have been widely used in many immune diseases.
OBJECTIVE:To investigate the effects of bone marrow mesenchymal stem celltransplantation on the CD4+CD25+regulatory T cells of peripheral blood in rats with primary nephrotic syndrome.
METHODS:Bone marrow mesenchymal stem cells from six Sprague-Dawley rats were isolated, passaged and utilized for cellsuspension preparation. At the third passage, bone marrow mesenchymal stem cells were used for transplantation. The remaining 30 rats were randomly and equal y divided into three groups:normal group, normal saline infusion group, and bone marrow mesenchymal stem cells group. The rat models of primary nephrotic syndrome were established by single injection of adriamycin intravenously through tail vein in the latter two groups. Rats were then treated with bone marrow mesenchymal stem cells (1×10 7 ) (bone marrow mesenchymal stem cells group) or normal saline (normal saline infusion group) through tail vein at the same time after adriamycin administration. The normal group received no treatment.
RESULTS AND CONCLUSION:Compared with the normal group, rats in the normal saline infusion group developed nephropathy characterized by ascites, proteinuria, hypoalbuminemia, hypercholastero-lnemia, and progressive renal injury. However, the proteinurine and clinical severity in bone marrow mesenchymal stem cells group were significantly ameliorated after treatment with bone marrow mesenchymal stem cells. CD4+CD25+Treg/CD4+Treg in the peripheral blood in the bone marrow mesenchymal stem cells group and normal saline infusion group were significantly higher than that in the normal group at 28 days after model establishment (P<0.05), while there was no significant difference between bone marrow mesenchymal stem cells group and normal saline infusion group (P>0.05). The expression of FoxP3 mRNA in the peripheral blood mononuclear cells of the bone marrow mesenchymal stem cells group was significantly higher than that in the normal saline infusion group and normal group (P<0.05). The bone marrow mesenchymal stem cells play a protective effect in rats with primary nephrotic syndrome, which may be related to the increase of local expression of FoxP3 and generation of CD4+CD25+Treg.

Objective To discuss the diagnostic value of peritoneal effusion detection by emergency-ultrasound in patients with closed abdominal injury. Method From August 2006 to June 2009,212 patients with closed abdominal injury were studied to evaluate peritoneal effusion detection by emergency ultrasound. Results of 212 patients,peritoneal effusion frequency rate was 78.8%( 167/212), meanwhile,abdominal paracentesis confirmation ratio was only 46.2%(98/212). In the follow-up, 13 patients with injuried hollow viscera and 1 patient with rupture of kidney showed peritoneal effusion. The volume of abdominal fluid was increasing in 17 patients,which needed to be managed by surgery. The accuracy rates were respectively 78.3%( 112/143) and 36.1%(13/36) in the solid organs and the hollow organs. Conclusion During the course of diagnosis and treatment in closed abdominal injury,peritoneal effusion monitoring by ultrasound should be used routinely, which can help to decrease the rate of misdiagnosis and avoid delayed treatment.
