Objective To assess the efficacy and safety of topical tacrolimus for erosive oral lichen planus(EOLP). Methods Literatures published up to December 2013 were searched from Pub Med, Embase, CENTRAL, Chinese Bio Medical Literature Database(CBM), and System for Information on Grey Literature in Europe(SIGLE). All randomized controlled trials(RCTs) of topical tacrolimus for EOLP which compared with other interventions or a placebo were considered in this Meta-analysis. Two researchers collected data independently. The assessment of methodological quality was based on Cochrane Handbook and the materials were analyzed with the software Revman 5.2.5. The primary outcome measures were the symptoms(e.g. pain, discomfort) complained by patients. The secondary outcome measures included the improvement rate of clinical signs assessed by the investigators and the incidence of adverse effects(e.g. clinical candidiasis). Results A total of 9 RCTs involving 476 patients were finally included. The pooled odds ratio(OR) of clinical improvement for topical tacrolimus vs. topical corticosteroids was 1.19 [95% confidence interval(CI): 0.64-2.22, I2: 44%]. Regarding to 0.1% tacrolimus and 0.03% tacrolimus, the pooled OR were 1.87(95 % CI: 0.60-5.82) and 1.47(95 % CI: 0.14-16.04) respectively in subgroup analysis. No serious adverse events were reported in topical tacrolimus group. Conclusions There was no evidence to support that topical tacrolimus for EOLP was more effective and safer than topical corticosteroids in this Meta-analysis. Clinical assessment criteria should be established and accepted by clinicians and researchers before further RCTs are undertaken.

Background: Cirrhotic patients are susceptible to Clostridium difficile infection(CDI), however, the high risk factors are not clear. The present study aimed to identify the risk factors in cirrhotic patients with CDI. Methods: A total of 526 cirrhotic patients admitted to our hospital between May 2015 and October 2015 were included in this study. Stool samples were collected upon admission for the detection of CDI and toxin. CDI was monitored during the hospital stay. In total, 34 cases showed CDI. Then we analyzed the effects of age, sex, C. difficile colonization(CDC), multiple hospitalization, extended hospital stay, elevation of total bilirubin(TBIL), creatinine(Cr), Child-Pugh grade C, hepatic encephalopathy, hepatorenal syndrome, upper gastrointestinal hemorrhage, and exposure of antibiotics and proton pump inhibitor(PPI) on the CDI in cirrhotic patients. Results: Patients in the CDI group had more frequent CDC, multiple hospitalization, and extended hospital stay compared to those in the non-C. difficile infection(NCDI) group. Patients in the CDI group had higher TBIL and Cr, and higher frequency of Child-Pugh grade C, hepatic encephalopathy, upper gastrointestinal hemorrhage compared with those in the NCDI group. Multiple logistic regression analysis indicated that age > 60 years(OR = 1.689;95% CI: 1.135–3.128), multiple hospitalization(OR = 3.346;95% CI: 1.392–8.043), length of hospital stay > 20 days(OR = 1.564;95% CI: 1.113–2.563), hypoproteinemia(OR = 4.962;95% CI: 2.053–11.996), CDC(OR = 18.410;95% CI: 6.898–49.136), hepatic encephalopathy(OR = 1.357;95% CI: 1.154–2.368), and exposure of antibiotics(OR = 1.865;95% CI: 1.213–2.863) and PPI(OR = 3.125;95% CI: 1.818–7.548) were risk factors of CDI. Conclusions: Age > 60 years, multiple hospitalization, length of hospital stay > 20 days, hypoproteinemia, CDC, hepatic encephalopathy, and exposure of antibiotics and PPI were risk factors for CDI in cirrhotic patients. These may contribute to the early diagno

Traditional movies feature men who are strong, powerful, intelligent, resourceful, women just being passive roles to facilitate the characterization of active men roles, even if the male characters are characterized as villains. The purpose of the arrangement of female characters in movies is to drive the narrative of the plot, to position female characters as the object of gaze so as to provide sexual pleasure for male spectators. This traditional characterization of females in movies is the representation of the orthodox patriarchy, intentionally or unintentionally. Whereas, analyzing from the perspective of male gaze, the movie, Taxi, completely overturns and mocks the orthodox patriarchy. The key character in the movie is Belle, a skillful female taxi driver, played by Queen Latifah. The male character, Andy Washburn, is characterized as being awkward, unmanly and uncollected, in need of help from Belle. This essay analyzes the characterization of the key characters in the movie to illustrate how it overturns and mocks the orthodox patriarchy.

Within the theoretical framework of English rhetoric, this paper analyzes the effect of imagery as a rhetorical device by Jane Austenin the novel Pride and Prejudice （2006）. Instances are cited with the use of imagery respectively in character portraits, dialogues, and scenes. It proves that an integrated use of this rhetorical device is an important means for vivid and impressive accounts in literary works, for it helps to build up the context for characterization, presenting the characters alive and distinctive, and effectively reveal the theme of the novel, bringing about authentic feelings to readers.
