Objective:To investigate the incidence and risk factors of renal injury in human immunodeficiency virus (HIV) infection/acquired immunodeficiency syndrome (AIDS) patients with poor immune reconstitution.Methods:The HIV infection/AIDS patients with poor immune reconstitution who were visited Second Department of Infection of Hangzhou Xixi Hospital from January to December 2021 were enrolled. The clinical data and laboratory examinations of the patients were collected, and the relevant risk factors were analyzed by logistic regression.Results:Among 303 HIV infection/AIDS patients with poor immune reconstitution, 59(19.5%) patients had renal injury. Logistic regression analysis showed that hypertension (odds ratio ( OR)=0.200, 95% confidence interval (95% CI) 0.065 to 0.618, P=0.005), taking tenofovir ( OR=0.275, 95% CI 0.130 to 0.580, P=0.001), hypoproteinemia ( OR=1.045, 95% CI 1.006 to 1.086, P=0.022), and low CD4 + T lymphocytes level ( OR=1.009, 95% CI 1.003 to 1.014, P=0.001) were risk factors for renal injury. Conclusions:The incidence of renal injury in HIV infection/AIDS patients with poor immune reconstitution is high. Hypertension, taking tenofovir, hypoproteinemia, and low CD4 + T lymphocytes level are risk factors for renal injury in patients.

Objective To observe whether pressure boost could induce changes in intracardiac pressures,and also to investigate the mechanism involved.Methods Seventeen healthy volunteers [13 males and 4 females,with an age range of 25.76 ± 5.16 years,and average age of 18-34] were recruited for the study.Without the knowledge of the examiners and examinees about the purpose of the research,they entered the hyperbaric chamber.The examiners detect the intraocular pressures (IOP) of the examinees with the Japanese NIDEK NT-2000 non-contact tonometer under the following conditions:(1) baseline intraocular pressures at rest.(2) during the stay at atmospheric pressure for 30 min without breathing pure oxygen; after breathing pure oxygen for 10 min at atmospheric pressure.(3) compression to a pressure of 60 kPa at a rate of 2.0 kPa/s without breathing pure oxygen; (4) during the stay at the pressure of 60 kPa for 30 min without breathing pure oxygen ; (5) after decompression to 0 kPa pressure,also without breathing pure oxygen.Results Average intraocular pressures measured during their stay at atmospheric pressure for 30 min without breathing pure oxygen,after breathing pure oxygen for 10 min at atmospheric pressure and after decompression to 0 kPa pressure without breathing pure oxygen were (13.57 ±3.04),(13.86 ± 3.16) and (13.33 ± 3.12) mmHg respectively.No statistical significance could be seen in measured data,as compared with that of the baseline intraocular pressures [(13.48 ± 2.87) mmHg] (P ＞ 0.05).Average intraocular pressures measured after they were compressed to 60 kPa without breathing pure oxygen and during their stay at 60 kPa for 30 min without breathing pure oxygen were (16.06 ±2.48) and (15.65 ± 2.54) mmHg respectively,and statistical difference could be seen,when compared with that of the baseline intraocular pressures(P ＞ 0.01).Conclusions When there was a pressure boost,most people would display elevated IOP due to poor response to pressure,only a few people would experience IOP drop also due to poor response to pressure and IOP of still a few people would remain basically unchanged.

OBJECTIVETo investigate the immune privilege induced by the Fas ligand (FasL) expressed by cotransplanted testicular Sertoli cells in islet allografts, and the effect of FasL gene transfection on islet cells in pancreatic islet allografts.

METHODSAllogeneic islets and testicular cells were cotransplanted into diabetic recipients. Pancreatic islets were infected with the recombinant adenovirus, AdV-FasL, and transplanted into diabetic recipients. Allograft survival, islet function, apoptosis of infiltrative lymphocytes in allografts and gene transfected islet allografts were analyzed.

RESULTSAll animals receiving islet allograft alone returned to a diabetic state in a few days (mean survival time 6.3 +/- 0.6 days). When the quantity of testicular cells cotransplanted with islets increased to 1 x 10(7), all animals remained normoglycemic throughout the follow-up period (60 days). FasL expression by cotransplanted Sertoli cells induced apoptosis of activated lymphocytes. Rejection of allografts in the FasL gene transfer group was accelerated and allograft survival was shortened to 3.4 +/- 0.2 days (P < 0.05). Pancreatic islets infected with AdV-FasL demonstrated positive staining for FasL at 24h after transplantation, with increased intensity at 48h. Apoptosis assays of pancreatic islet allografts at 24h and 48h revealed apoptosis of transfected islets.

CONCLUSIONSFasL-expressing testicular Sertoli cells can induce apoptosis of activated lymphocytes. Cotransplantation of testicular cells allows long-term survival of allogeneic islets because of immune privilege, but the direct expression of FasL on islet allografts infected with AdV-FasL accelerates islet rejection via islet apoptosis and granulocyte infiltration.

Objective To evaluate J-pouch coloanal anastomosis after low anterior resection for the middle and low rectal carcinoma. Methods From January 1998 to July 2002, 120 patients undergoing low anterior radical resection for the middle or low rectal carcinomas were divided into groups of coloanal anastomosis and that of 5 cm colonic J-pouch-anal anastomosis. WT5”HZResults These two groups were well matched for gender, age and histologic stage. There were no significant differences in operative time, hospital stay, complications, postoperative recurrence rate and postoperative survival time between the two groups as founded by an average follow-up of 18 months. The mean distance from the inferior edge of the tumor to the dentate line was (3 6?1 5) cm in the J-pouch group, significantly less than that in coloanal anastomosis group of (5 2?1 9) cm, ( P =0 000). Defecation frequency, urgency and incontinence were significantly improved at 3 months and 12 months after operation in the J-pouch group ( P 0 05). Conclusion J-pouch coloanal anastomosis after low anterior resection for the middle and low rectal carcinoma significantly improves the short-term bowel function after operation.

Objective To investigate the correlation between clinicopathologic factors and peritoneal dissemination from gastric cancer, and the impact of palliative resection on the prognosis of patients with gastric cancer complicated by peritoneal dissemination. Methods Based on our database built in 1994, the clinicopathologic data and the result of follow-up of all gastric cancer patients were analyzed retrospectively using the software of SPSS. Results One hundred and five out of 792 (13. 3% ) patients with primary gastric cancer were found complicated with peritoneal dissemination. The clinicopathologic factors in patients with peritoneal dissemination were significantly correlated with primary tumor penetrating through serosa, lymph node metastasis, primary tumor involving whole stomach, undifferentiated carcinoma, Borrmann IV and female gender (P
