Trospium chloride is an anticholinergic agent with predominantly peripheral nonselective antimuscarinic activity and water solubility. It has potential therapeutic value in decreasing detrusor contracivity and tonity, so as to increase predominantly mean maximal bladder capacity and compliance. Multicenter studys showed that the tolerability and efficacy of trospium chloride was as same as oxybutynin and better than toterodine. Adverse events of trospium chloride is the same as other anticholinergic agents, however its specially constitutional feature so as not to have toxicity to central nervous system. Trospium chloride has potential therapeutic value in the neurourological rehabilitation.

Objective To evaluate the curative efficacy of endoscopic retrograde cholangiopancreatography (ERCP) on bile leaks after orthotopic liver transplantation (OLT). Methods Data of 12 cases, hospitalized in our hospital from March 2013 to February 2016, with bile leaks after OLT confirmed by magnetic resonance imaging of the pancreas (MRCP) or ERCP were retrospectively analyzed . The curative efficacy of ERCP was evaluated including clinical symptoms of bile leaks and complications, occurrence time and location, diagnosis and treatment process and efficacy. Results In this study, 12 cases were male patients, with the average age of 49.75 ± 8.55 (age from 35 to 62 years old). Among them 11 cases were successfully treated by endoscopic nasobiliary drainage (ENBD), and the success rate of endoscopical therapy was 91.7%, the curative rate of bile leaks was 91.7%(11/12). No ERCP related serious complications and death were found in patients. Nine cases combined with biliary strictures and/or biliary duct stone/bile plug were performed endoscopic sphinctrotomy (EST) during the first time of ERCP, and accepted further ERCP treatment after 2 weeks when the bile leaks were healed. All patients with ENBD were carried out well except one case. Conclusion ERCP is a safe and effective minimally invasive treatment method for different types of bile leaks after OLT.

This study was designed to use iTRAQ technology coupled with 2D LC-MS/MS to study the comparative proteomics of different processing technology for pilose antler. 1015 proteins were identified with 2D LC combined with MOLDI TOF/TOF mass spectrometry. Comparative analysis with Protein Pilot (Version 4.5) revealed that 87 proteins were changed (P ≤ 0.05, the ratio of > 1.50 or < 0.60 as the threshold selection of difference proteins), of which 24 were up regulated and 33 were down regulated in the traditional frying process (TFP) compared with the fresh pilose antler (P ≤ 0.05). 7 significant different proteins (P ≤ 0.001), most of these significantly changed proteins were found to be involved in calcium ion binding and ATP binding associated with human healthy. Freeze drying with protective agent (FDP) (Trehalose) can improve the content of significantly different proteins (P ≤ 0.001) including Collagen alpha-1 (XII) chain (COL12A1) and Collagen alpha-1 (II) chain (COL2A1). The significant function involves in platelets activating, maintenance of spermatogonium, and disorder expression in tumor cells. The functional annotation by Hierarchical clustering and GO (gene ontology) showed that the main molecule functions of the proteins significantly changed in these processes were involved in binding (52.7%), catalytic (25.3%), structural molecule and transporter (6.6%).

One unusual human G3P[3] group A rotavirus (RVA) strain M2-102 was identified in stool sample collected from a child with diarrhea in Guangxi Province, China in 2014. It is well known that G3P[3] is a genotype commonly identified in feline and canine RVAs. However, the preliminary phylogenetic analyses of the VP7 and VP4 genes of strain M2-102 indicated that these two genes were closely related to bat RVA strain MYAS33 and simian strain RRV, respectively, whereas both clustered distantly to feline/canine-like RVA strains. In this study, full genome sequencing and molecular analyses were conducted to obtain the true origin of strain M2-102. It was revealed that strain RVA/Human-wt/CHN/M2-102/2014/G3P[3] exhibited a G3-P[3]-I3-R3-C3-M3-A9-N3-T3-E3-H6 genotype constellation for VP7-VP4-VP6-VP1-VP2-VP3-NSP1-NSP2-NSP3-NSP4-NSP5 genes. Phylogenetic analyses revealed that 5 genes (VP7, VP1, VP2, NSP2 and NSP3) from strain M2-102 were closely related to those of bat strain MYAS33 from Yunnan Province which was thought a true bat RVA strain rather than a virus transmitted between species, while another 5 genes (VP4, VP3, NSP1, NSP4 and NSP5) clustered closely with those of simian strain RRV, yet the VP6 gene was closely related to that of human G3P[9] strain AU-1 and AU-1-like RVAs. The epidemiological data indicated that the child infected with M2-102 came from a countryside village, located in Dong Autonomous County of Sanjiang (subtropical hilly wooded area), Liuzhou city in Guangxi Province which might provide natural environment for reassortment events occurring among animal and human RVAs. Therefore, the data suggest that human strain M2-102 might originate from multiple reassortment events among bat, simian and human AU-1-like RVAs, yet it is not clear whether the genomic backbone based on bat MYAS33 (5 genes) and simian RRV (5 genes) like rotaviruses had been obtained through reassortment before being transmitted to the human. This is the first report on whole genome analysis of human G3P[3] RVA from China.

Objective:To determine the expression profile and potential roles of CD24 in oral squamous cell carcinoma and explore the values of CD24 function as a potential target of clinical therapy.Me-thods:Semi-quantitative immunohistochemistry was used to construct the expression profile of CD24 in 78 human oral tissues and 59 Hamster buccal pouch tissues.Real-time RT-PCR and Western blot were used to analyze the CD24 expression levels in oral DOK4 cells,oral cancer CAL-27 and WSU-HN6 cells. Then these two cancer cell lines were selected to evaluate the effect of all-trans retinoic acid (ATRA)and CD24 antibody on CD24 expression,and the proliferation and tumorsphere formation capacity of these two cell lines.Results:CD24 expression was found significantly elevated in both human and animal tissues compared with normal and benign tissues (P<0.05),as well as in oral cancer CAL-27 and WSU-HN6 cells compared with DOK cells (P<0.05).CAL-27 and WSU-HN6 cells possess increased proliferative and specific tumorsphere formation capability compared with DOK cells (P<0.05 ).Both ATRA and CD24 antibody were able to effectively inhibit the proliferation and tumorsphere formation of CAL-27 and WSU-HN6 cells (P<0.05).Among them ATRA at least involved partially in the proliferation by down-regulating the CD24 expression (P<0.05 ),while CD24 antibody blocking had no effect on the CD24 expression.Conclusion:CD24 was upregulated in oral cancer and functioned as a potential factor that promoted the proliferation and tumorsphere formation of CAL-27 and WSU-HN6 cells.Both ATRA and CD24 antibody might effectively inhibit the proliferation and tumorsphere formation of CAL-27 and WSU-HN6 cells and function as a potential therapy target.
