Recent evidence suggests that the fat mass and obesity-associated gene (FTO) genotype may interact with dietary intakes in relation to adiposity. We tested the effect of FTO variant on weight loss in response to 2-year diet interventions. FTO rs1558902 was geno-typed in 742 obese adults who were randomly assigned to one of four diets differing in the proportions of fat, protein, and carbohydrate. Body composition and fat distribution were measured by dual-energy x-ray absorptiometry and computed tomography. We found significant modification effects for intervention varying in dietary protein on 2-year changes in fat-free mass, whole body total percentage of fat mass, total adipose tissue mass, visceral adipose tissue mass, and superficial adipose tissue mass (for all interactions, P < 0.05). Carriers of the risk allele had a greater reduction in weight, body composition, and fat distribution in response to a high-protein diet, whereas an opposite genetic effect was observed on changes in fat distribution in response to a low-protein diet. Likewise, significant interaction patterns also were observed at 6 months. Our data suggest that a high-protein diet may be beneficial for weight loss and improvement of body composition and fat distribution in individuals with the risk allele of the FTO variant rs1558902. © 2012 by the American Diabetes Association.

To identify new genetic risk factors for cervical cancer, we conducted a genome-wide association study in the Han Chinese population. The initial discovery set included 1,364 individuals with cervical cancer (cases) and 3,028 female controls, and we selected a 'stringently matched samples' subset (829 cases and 990 controls) from the discovery set on the basis of principal component analysis; the follow-up stages included two independent sample sets (1,824 cases and 3,808 controls for follow-up 1 and 2,343 cases and 3,388 controls for follow-up 2). We identified strong evidence of associations between cervical cancer and two new loci: 4q12 (rs13117307, Pcombined, stringently matched = 9.69 × 10-9, per-allele odds ratio (OR)stringently matched = 1.26) and 17q12 (rs8067378, Pcombined, stringently matched = 2.00 × 10-8, per-allele ORstringently matched = 1.18). We additionally replicated an association between HLA-DPB1 and HLA-DPB2 (HLA-DPB1/2) at 6p21.32 and cervical cancer (rs4282438, Pcombined, stringently matched = 4.52 × 10-27, per-allele ORstringently matched = 0.75). Our findings provide new insights into the genetic etiology of cervical cancer. © 2013 Nature America, Inc. All rights reserved.

Objective: To re-evaluate the efficacy of Meniett therapy for the treatment of Ménière's disease (MD). Data Sources: PubMed, Embase, Cochrane Library, Clinicaltrials. gov, ChiCTR, and the CNKI database were searched for articles in English and Chinese published before August 31, 2015. Study Selection: Included in this meta-Analysis were studies that dealt with outcomes of Meniett therapy for the treatment of MD, including randomized controlled clinical trials, casecontrol studies, and prospective or retrospective cohort studies, with sample sizes of-10 subjects. Data Extraction: Keywords included endolymphatic hydrops, Ménière's disease, pressure, Meniett, and transtympanic micropressure treatment. Data Synthesis: Fourteen studies were included, involving a total of 345 MD patients. Data were analyzed using the Meta package in R. Dichotomous outcomes were expressed as risk ratios with 95% confidence intervals, and weighted mean differences with 95% confidence intervals were used to present continuous outcomes. Heterogeneity of the included studies was quantitatively assessed by x2 and I2 tests. Fixedeffects models were used for I2<50%; otherwise, randomeffects models were used. Funnel plots were constructed to test the publication bias. Conclusion: This study showed that Meniett therapy may prevent vertigo attacks and substantially reduce its frequency in MD patients. It may also alleviate the functional deficit. The impact of Meniett therapy on hearing remains uncertain. The optimal effect might maintain for approximately 18 months. This meta-Analysis suggested that Meniett therapy may be a useful second-line therapy in the treatment of MD. © 2016, Otology & Neurotology, Inc.

Background: Schistosomiasis remains a major public health problem in China. The major endemic foci are the lake and marshland regions of southern China, particularly the regions along the middle and lower reach of the Yangtze River in four provinces (Hubei, Hunan, Jiangxi, and Anhui). The purpose of our study is to assess the effect of a new integrated strategy emphasizing infection source control to curb schistosomiasis in marshland regions. Methods: In a longitudinal study, we implemented an integrated control strategy emphasizing infection source control in 16 villages from 2005 through 2012 in marshland regions of Hubei province. The interventions included removing cattle from snail-infested grasslands, providing farmers with mechanized farm equipment, improving sanitation by supplying tap water, building lavatories and latrines, praziquantel chemotherapy, controlling snails, and environmental modification. Results: Following the integrated control strategy designed to reduce the role of bovines and humans as sources of Schistosoma japonicum infection, the prevalence of human S. japonicum infection declined from 1.7% in 2005 to 0.4% in 2012 (P,0.001). Reductions were also observed in both sexes, across all age groups, and among high risk occupations. Moreover, the prevalence of bovine S. japonicum infection decreased from 11.7% in 2005 to 0.6% in 2012 (P,0.001). In addition, all the 16 villages achieved the national criteria of infection control in 2008. Conclusion: Our findings indicate that the integrated strategy was likely effective in controlling the transmission of S. japonicum in marshland regions in China.©2014 Chen et al.
