AIM: To investigate the effects of advanced glycation end products (AGEs) on the expression of plasminogen activator inhibitor-1 (PAI-1) in rat mesangial cells and its relationship with extracellular matrix accumulation. METHODS: Rat mesangial cells were treated with AGE-modified bovine serum albumin or native bovine serum albumin. Normal mesangial cells without any treatments were used as control. Fibronectin (FN), collagen Ⅳ, PAI-1 protein contents were detected by ELISA. PAI-1 mRNA was analyzed by reverse transcriptase-polymerase chain reaction (RT-PCR). RESULTS: AGEs (0-200 mg/L) did not influence mesangial cells proliferation, but stimulated FN , collagen IV and PAI-1 contents in mesangial cell cultured medium in different degrees. AGEs also increased PAI-1 mRNA expression. CONCLUSION: AGEs increase the expression of PAI-1 in rat mesangial cells. AGEs may reduce ECM degradation through increasing PAI-1 expression, which may be one of the mechanisms of ECM accumulation in diabetic nephropathy.

Objective To investigate the effects of advanced glycation end products(AGEs) on expression of peroxisome proliferator-activated receptor-?(PPAR?) mRNA in rat renal cortex.Methods Normal rats were given tail vein injection with either AGE-modified rat serum protein(AGEs)or AGE-RSP followed by intraperitoneal injection of AG(AGEs+AG)or native rat serum protein(native RSP).Normal rats without any treatment were as controls(Control).PPAR-? mRNA expression was analysed by reverse transcriptase-polymerase chain reaction(RT-PCR).Results PPAR-? mRNA expressed in all rat kidney cortex.There was a decrease for PPAR-? in mRNA levels in the renal cortex of AGEs-treated rats(P

Objective To explore the effect of boiled fenugreek seeds on renal matrix metalloproteinase-2(MMP-2) activity in diabetic rats.Methods The model of diabetes was built with STZ in rats.The model rats were randomly divided into diabetes control groups (DM ) (n=10) and fenugreek seeds groups(FN) (n=10,and while normal control group (N) (n=10)rats was used.Diabetic rats were treated with fenugreek seeds for 12 weeks,the renal morphology and MMP-2 activity were observed in three groups .Results After diabetic rats were treated with fenugreek seeds for 12 weeks,optical microscopic examination indicated that the glomerular structure in N group was normal,the glomerular lesions in rats of DM groups were seriously and the pathologic changes of glomerular in rats of FN groups were alleviated significantly.Immunohistochemical results showed that the Col Ⅳ expression in glomerular ECM was increased in DM group compared with N group,and was decreased in FN group.The activity of MMP-2 was increased in FN group (1.41?0.18) compared with DM group (1.05?0.19) (P

Objective To study the effects of different anesthesia methods on postoperative changes in T-lymphocyte subsets and IL-6、IL-10、TNF-α in the patients undergoing operation of stomach carcinoma.Methods 60 patients with stomach carcinoma were randomly divided into group I(general anaesthesia)and Ⅱ(general combined epidural anesthesia).The level of T-lymphocyte subsets and IL-6、IL-10、TNF-αt were respectively detected and compared before anesthesia,2 h after anesthesia,ld and 6 d after operation.Results CD3+ 、CD4+ 、CD4+/CD3+ decreased,but IL-6 increased at the end of 2 h after anesthesia,l d after operation compared with those before anesthesia(all P＜0.05).While IL-10、TNF-α had no statistical significance(all P＞0.05).At 6 d after operation,the values recovered to the level before anesthesia in two groups.Conclusion The immune function in patients with gastric cancer decreaseed after anesthesia,it was more serious in geteral anaesthesia than that of general combined epidural anesthesia.But anesthesia had little influence on inflammatory response.

Objective To explore the effect of jejunostomy in radical operation of esophageal cancer through right thoracotomy and abdominal incision. Methods A total of 90 esophageal cancer patients who had undergone radical resection through right thoracotomy and abdominal incision were retrospectively analyzed, among whom 50 cases used enteral nutrition via jejunostomy (jejunostomy group) and 40 cases via naso- intestinal tube (naso- intestinal tube group). The operation time, hospitalization time after operation, retention time of tube, complication and nutritional status after operation were compared between 2 groups. Results There were no statistical differences in the operation time and hospitalization time after operation between 2 groups (P>0.05). All the patients of 2 groups could tolerate the enteral nutrition. The retention time of tube in jejunostomy group was significantly longer than that in naso- intestinal tube group jejunostomy: (18.08 ± 9.28) d vs. (14.85 ± 4.59) d, and there was statistical difference (P<0.05). There was no statistical difference in the albumin before operation between 2 groups (P>0.05). The albumin after 1 week′s enteral nutrition in jejunostomy group was significantly higher than that in naso-intestinal tube group:(30.99 ± 2.79) g/L vs. (29.72 ± 3.16) g/L, and there was statistical difference (P<0.05). During the period of observation, the patients of naso-intestinal tube group had different degrees of nasopharyngeal region discomfort. The incidences of tube obstruction/ tube shedding and the complication in jejunostomy group were significantly lower than those in naso-intestinal tube group: 0 vs. 10% (4/40) and 18% (9/50) vs. 50%(20/40), and there were statistical differences (P<0.05). Conclusions Jejunostomy is a safer and more effective nutrient method in radical operation of esophageal cancer through right thoracotomy and abdominal incision.
