Aim: To study the effect of Eudragit S-100, a pH-responsive polymer, on protein refolding level, using recombinant human keratinocyte growth factor-2 (rhKGF-2) as a model protein. Methods: The refolding of rh-KGF-2 was performed by directly diluting denatured rhKGF-2 into a refolding buffer containing different concentrations of Eudragit. The ability of Eudragit S-100 to enhance protein refolding level was investigated using MTT assay, reverse phase HPLC, fluorescence emission spectroscopy and circular dichroism spectroscopy. Results: The addition of Eudragit S-100 in the refolding buffer significantly increased the rhKGF-2 refolding yield to 71%, when dilution refolding was conducted at 0. 5 mg/mL rhKGF-2. The outcome from the refolding study showed possibility of a special interaction between rhKGF-2 and Eudragit, suggesting that the refolding-enhancing ability of Eudragit S-100 was due to this interaction between Eudragit S-100 and rhKGF-2. Mean while, the result showed that the concentration of urea was also an important factor for the optimization of the refolding in the presence of Eudragit. Conclusion: Eudragit S-100 can significantly increase the refolding level of rhKGF-2.

ObjectiveTo determine whether antibiotic prophylaxis can reduce the risk of postoperative infective complications in men undergoing transrectal prostatic biopsy (TPB) who had sterile preoperative urine.MethodsMEDLINE, EMBASE, Cochrane Collaboration Reviews, Chinese Medical Current Contents (CMCC), and National Knowledge Infrastructure (CNKI) were searched for rando-mized controlled trials that compared the effect of antibiotic prophylaxis with placebo or active controls for men undergoing TPB with preoperative sterile urine. Two reviewers independently extracted the data of patient characteristics and outcomes based on a prospectively developed protocol.ResultsA total of 12 trials (3 placebo controlled, 3 non-treatment controlled, and 6 activly controlled) involving 1 987 patients, met the inclusion criteria. Prophylactic antibiotic use in patients at low risk undergoing TPB significantly decreased bacteriuria and middle degree fever incidence, but could not decrease the incidence of bacteremia. The relative risk for post-TPB bacteriuria, middle degree fever, and bacteremia were 0.32 (95% CI 0.23 to 0.46), 0.37 (95% CI 0.17 to 0.77), and 0.96 (95% CI 0.61 to 1.50), respectively. Effective antibiotic classes included quinolone, co-quinolone and nitroimidazole, and co-trimethoprim and sulfamethoxazole. Treatment protocols of any duration were effective.ConclusionAntibiotic prophylaxis obviously decreases the incidence of bacteriuria and middle degree fever but not bacteremia in men with preoperative sterile urine undergoing TPB. A significant decrease in bacteriuria incidence can be achieved with a range of antibiotic agents, including quinolones and co-quinolone and nitroimidazole. Treatment protocols of any duration are effective with no heterogeneity.

Objective To systematic review bladder tumor antigen(BTA) stat in the diagnosis of bladder cancer. Methods MEDLINE, EMBASE, Cochrane Library, CMCC and CNKI were searched for studies about BTA stat in the diagnosis of bladder cancer. The search strategy was made according to the Collaborative Review Group search strategy. Data were extracted by two reviewers using the designed extraction form. The software MetaDiScl. 4 was used to review management and data analysis. Results Seventy-one relevant studies were searched, of which 20 studies were included with 5929 patients involved and 51 studies were excluded. Heterogeneity (except for threshold effect) was found within these studies. A meta-analysis was performed using random effect model. Pooled accuracy indicators like sensitivity, specificity, positive likelihood ratio (LR), negative LR and diagnostic odds ratio (dOR) were 0. 64(95%CI 0. 62-0. 66), 0. 72(95%CI 0. 70-0. 73) , 2. 33(95% CI 2. 03-2. 68), 0. 48(95%CI 0.42 -0.55) and 5.12(95%CI 3. 88-6. 75), respectively. The sensitivity increased with tumor grades. The sensitivity of primary tumors was higher than the recurrent tumors. Area under curve (AUC) of SROC curve was 0. 7500 and Q* index was 0. 6934. Conclusions The performance of urine BTA stat is moderate in the diagnosis of bladder tumor. It can be an optional non-invasive test and an important adjunct test in preoperative detecting and postoperative monitoring of bladder tumor.
