Objective To assess the relationship between type 2 diabetes and the risk of kidney cancer. Methods PubMed, Medline, CNKI and VIP were used to identify studies which regarded the relationship between type 2 diabetes and risk of kidney cancer up to July 2014. The relative risks (RRs) and the corresponding 95% confidence interals (CIs) were used to estimate the association between type 2 diabetes and the risk of kidney cancer through software STATA. Results 8 studies were included in this analysis. Compared to the popula-tion without type 2 diabetes, there was an increased risk of kidney cancer in the type 2 diabetes patients, the pooled RR (95%CI) was 1. 55 (1. 24,1. 92),P<0. 05. Conclusion Our meta-analysis suggestes that type 2 diabetes can increase the risk of kidney cancer.

To establish a new kind of minimally invasive surgical model of transurethral prostate enucleation operation and method that makes the operation easier and reduces the surgeon learning curve.According to the order and the path of surgical operation,prostate enucleation operation is split into 4 different modules named as A,B,C,D,and it is called modular transurethral enucleation of the prostate.The operation mode optimizes the process of operation design, modularizes the contents of surgical procedures,processes,and reduces the difficulty of the operation,and simplifies the surgical procedure,which can effectively shorten the operation time and make it easy for beginners to carry out and control the procedure.It has a great popularization value.

Objective To analyze and evaluate the effects of the tissue engineering bladder reconstruction on the upper urinary tract structure and function.Methods The 8 male beagles were randomly divided into the two groups:sham-operation group (group A,n=4)and the collagen scaffold repair group (group B,n=4).The bladder defect animal model was established in the group B by using the collagen scaffold materials to repair the bladder.The renal function related biochemical indicators were detec-ted and the renal Doppler ultrasonic examination was performed in each group before repair and in 23 weeks after repair.The speci-mens from the two groups were performed the gross morphology observation and the histology examination on postoperative 24 weeks.Results The renal Doppler ultrasound examination showed the normal kidney morphology and normal blood flow signal.In the general observation,no calculi and neoplasm were found in the kidney and ureter of the experimental dogs.The renal function related biochemical indicators had no statistically significant differences between the two groups(P>0.05).The histological exami-nation indicated that the organization structure was integrity,the nephrons in each group had no obvious pathological changes.Con-clusion Using the collagen scaffold materials to reconstruct the canine bladder has no adverse influence on the upper urinary tract structure and function,this tissue engineering approach has good feasibility.

OBJECTIVE:To investigate the effects of long-term use of calcium channel blocker-Diltiazem(Dil)on the dosage of ciclosporin A and renal function of renal graft recipients.METHODS:Dil was administed in67renal graft recipi?ents,meanwhile who were orally taking CsA with another59renal graft recipients served as controls.The dosages of ci?closporin A of2group were adjusted to the level within therapeutic window,then the dosage of CsA and serum creatinine change of the2groups36mo after drug administration were observed.RESULTS:12mo,24mo and36mo after operation,the synchronized cyclosporin A dosages in Dil group were lower than the control group respectively by14353mg,9656mg and7817mg.No significant differences were found in serum creatinine levels between the2groups within the first12mo after operation.Thereafter,the creatinine levels in the control group has a faster increase and the creatinine level in Dil group was significantly lower than that of the control group18mo~36mo after operation(P

Objective:To comprehensively evaluated the quality of Sargentodoxae Caulis from different habitats with a combination of indexes and characteristic chromatogram method from Chinese Pharmcopoeia (Edition 2020). Methods:The contents of water content, total ash, ethanolic extract, sulfur dioxide residue, heavy metals and harmful elements, total phenols, chlorogenic acid, salidroside and characteristic chromatogram of 17 batches of Sargentodoxae Caulis were determined. The quality of Sargentodoxae Caulis was comprehensively evaluated by combining chemical pattern recognition method. Results:The water content, total ash content, extracts, and content determination of 17 batches of Sargentodoxae Caulis from different habitats complyed with the provisions of the Chinese Pharmcopoeia (Edition 2020). There were differences in the contents of extracts, chlorogenic acid, and salidroside, among which the content of Anhui origin was higher. A total of 8 common peaks were identified from the 17 batches samples. Conclusion:Comprehensive evaluation of multiple indicators can demonstrate the quality of Sargentodoxae Caulis more correctly, and shows that the quality of Sargentodoxae Caulis from different habitats is different. The quality of Sargentodoxae Caulis from Anhui is better than that from other habitats.

Objective:To explore the interventional effect of β-sitosterol on ovalbumin(OVA)-induced allergic asthma rats and its potential mechanism.Methods:SD male rats were randomly divided into normal group(CON),model group(M),positive drug dexamethasone group(DEX,0.075 mg/kg)and β-sitosterol group(Sit,50 mg/kg).A rat model of allergic asthma was estab-lished by intraperitoneal injection of OVA with aluminum hydrogen solution,and nebulized inhalation of OVA to stimulate.Rats were given intragastric administration 30 min before aerosol challenge,and after continuous administration for 7 days,the indicators of cough and asthma and tracheal phenol red excretion were detected.HE staining was used to observe pathological changes of lung tis-sue.Flow cytometry was used to detect reactive oxygen species(ROS)generation,apoptosis level and ratios of Th17 and Treg cells in peripheral blood.Biochemical method was used to detect contents of MDA,and activities of T-SOD and GSH-Px in rat lung tissues.ELISA was used to detect levels of Th17 and Treg-related cytokines(TNF-α,IL-4,IL-6,IL-17A,and IL-35).Results:Compared with model group,β-sitosterol significantly prolonged the incubation period of cough and gasp in rats with allergic asthma,reduced the frequency of cough and gasping,and promoted the excretion of phenol red in trachea;significantly reduced inflammatory infiltration in lung tissue of asthmatic rats;observably reduced MDA content in lung tissue,ROS of primary lung cell and apoptosis levels of asthmatic rats,increased the activities of T-SOD and GSH-Px;markedly reduced proportion of Th17 cells and levels of pro-inflammatory cyto-kines TNF-α,IL-4,IL-6 and IL-17A,increased proportion of Treg cells and levels of anti-inflammatory cytokine IL-35.Conclusion:β-sitosterol can ameliorate airway inflammation and oxidative damage in OVA-induced allergic asthmatic rats,and its mecha-nism may be related to the regulation of β-sitosterol on Th17/Treg immune imbalance and oxidative stress response.
