Objective To study the expression of survivin, an apoptosis inhibitor gene,in bladder carcinoma,and to investigate its clinical and pathological implications. Methods We detected the expression of survivin in 60 cases (48 men and 12 women) of bladder carcinoma and 10 cases of non-tumor bladder tissues (controls) by immunohistochemistry (SP) method.The mean age of the 60 cases at diagnosis was 59 years.The pathological grading showed Grade Ⅰ in 16 cases,Grade Ⅱ in 24 and Grade Ⅲ in 20.The clinical staging showed T 1 in 13 cases,T 2 in 15,T 3 in 21 and T 4 in 11.Of the 60 cases,21 developed relapse. Results The overall positive rate of survivin in 60 cases of bladder carcinoma was 60.0% (n=36).No survivin was found in 10 cases of non-tumor bladder tissues.The positive rate of survivin in Grade Ⅰ cases of bladder carcinoma was 37.5%(6/16),in Grade Ⅱ and Ⅲ cases of bladder carcinoma was 66.7%(16/24) and 70.0%(14/20);the difference of positive rates between Grade Ⅰ and Grade Ⅱ,Grade Ⅲ cases was significant (P0.05).The positive rate of survivin in cases of relapse was 80.9% (17/21). Conclusions Survivin may play an essential role in bladder carcinogenesis and serve as a marker for prognosis of bladder cancer.

Objective To explore the effect of nitric oxide(NO) on pulmonary tumor necrosis factor?(TNF?) in murine acute necrotizing pancreatitis(ANP). Method Ninety-six SD rats were randomized into four groups:normal control group, ANP group, L-Arginine(L-Arg) pretreatment group and L-NAME pretreatment group (n=24 for each group). The protein content of bronchoalveolar lavage fluids(BALF), the myeloperoxidase(MPO) of lung tissue and TNF? produced by alveolar macrophages were evaluated. The expression of TNF? mRNA was measured. ResultMPO and protein of BALF reached a peak level at 12nd hr (10.78?0.58U/g for MPO and 2011?106?g/ml for protein content respectively).TNF? peaked on the sixth hour(1624?149)pg/ml. The expression of AM TNF?mRNA also peaked on the sixth hour (1.127?0.069) along with an increase of TNF? mRNA. A similar tendency was seen in L-Arg and L-NAME pretreatment groups, with changes being statistically different in the three groups when compared with that of normal control group(P

Objective:To explore the clinical efficacy, especially the comprehensive improvement of blood glucose and lipid of probucol and metformin in the treatment of type 2 diabetes mellitus with hyperlipidemia. Methods:Totally 105 patients with type 2 di-abetes mellitus complicated with hyperlipidemia were randomly divided into the control group1 (35 cases), the control group 2 (34 ca-ses) and the observation group (36 cases). The control group 1 was treated with diet control, exercise and metformin, the control group 2 was treated with rosuvastatin calclum tablets based on the group 1, and the observation group was treated with probucol based on the group 1. The three groups were continuously treated for 12 weeks. The improvement of the fasting blood-glucose (FPG), 2h postprandial blood glucose (PBG), hemoglobin A1C (HbA1C), fasting insulin levels (Fins), insulin resistance indices (HOMA-IR) and TC, TG and HDL-C, and the adverse reactions among the three groups were compared. Results:The total effective rate in the ob-servation group was higher than that in the control group 1 and 2 (P<0. 05). After the treatment, all the indices of blood glucose and lipid in the three groups were significantly improved (P<0. 05), and those of blood glucose in the observation were better than those in the control group 1 and 2(P<0. 05), those of blood lipid in the observation group and the control group 2 were better than those in the control group 1 (P<0. 05), and the level of HDL-C in the observation group was much higher than that in the control group 2 (P<0. 05). The adverse drug reactions in the three groups were mild without statistical significance (P>0. 05). Conclusion:Probucol as one of lipid-lowing drugs with antioxidant action combined with metformin can improve blood lipid and lower blood glucose at the same time, which is worthy of promoted application in clinics.

Objective To compare iso-osmolar iodixanol and low-osmolar iohexol for the incidence of contrast- induced nephropathy(CIN) in patients with chronic congestive heart failure undergoing coronary interventional therapy. Methods The study included 220 consecutive patients with chronic congestive heart failure and undergoing coronary angiography (CAG) with or without percutaneous coronary intervention (PCI) bewteen Janurary 2015 and May 2016. Study participants were divided into two groups by random digits table:iso-osmolar group (110 patients) and low-osmolar group (110 patients). The patients in iso-osmolar group were given iodixanol, and the patients in low-osmolar group were given iohexol. Serum creatinine (SCr), glomerular filtration rate (GFR) and cystatin C (CysC) were detected before the procedure and on the first, third day after the procedure. Then, the incidence of contrast-induced nephropathy (CIN) in two groups within 72 h of the procedure were observed and compared. Results The levels of SCr, GFR, CysC before operation had no significant differences (P>0.05). The levels of SCr in two groups on the first day after operation were increased, but there was no significant difference between two groups (P>0.05). On the first day after operation, the level of GFR in iso-osmolar group was higher than that in low-osmolar group, the level of CysC in iso-osmolar group was lower than that in low-osmolar group, and there were significant differences (P<0.05). On the third day after operation, the level of GFR in iso-osmolar group was higher than that in low-osmolar group, the level of CysC in iso-osmolar group was lower than that in low-osmolar group, and there were significant differences (P<0.01). The overall incidence of CIN was 20.9%(46/220). The incidence of CIN in low-osmolar group was 29.1%(32/110), in iso-osmolar group was 12.7%(14/110), and there was significant difference (P<0.05). Conclusions In chronic congestive heart failure patients undergoing coronary interventional therapy, the iso-osmolar contrast iodixanol is associated with a lower incidence of CIN compared with low-osmolar iohexol.
