Novel insights into causal effects of maternal nonalcoholic fatty liver disease on adverse pregnancy outcomes: evidence from Human Genetics and Mendelian Randomization Study.

Background: Observational studies have associated nonalcoholic fatty liver disease (NAFLD) with adverse pregnancy events, but findings show heterogeneity, leaving the causal direction and mediating pathways unclear. We aimed to investigate the causal relation between NAFLD and various pregnancy events, and to elucidate the underlying mediating pathways while determining the proportion of this correlation that is mediated through these pathways.

Methods: A genome-wide association study involving over 6 million participants employing Mendelian randomization (MR) and mediation analysis was performed.

[Nasal endoscopy-assisted bulboprostatic anastomosis for posterior urethral stricture].

Objective: To study the clinical value and operation skills of nasal endoscopy-assisted bulboprostatic anastomosis in the treatment of posterior urethral stricture.

Methods: Between January 2012 and November 2014, we performed nasal endoscopy-assisted bulboprostatic anastomosis for 12 male patients with posterior urethral stricture. We recorded the operation time, blood loss, exposure of operation visual field, and success rate of anastomosis and summarized the operation skills.

Efficacy of neonatal HBV vaccination on liver cancer and other liver diseases over 30-year follow-up of the Qidong hepatitis B intervention study: a cluster randomized controlled trial.

Background: Neonatal hepatitis B vaccination has been implemented worldwide to prevent hepatitis B virus (HBV) infections. Its long-term protective efficacy on primary liver cancer (PLC) and other liver diseases has not been fully examined.

Methods And Findings: The Qidong Hepatitis B Intervention Study, a population-based, cluster randomized, controlled trial between 1985 and 1990 in Qidong, China, included 39,292 newborns who were randomly assigned to the vaccination group in which 38,366 participants completed the HBV vaccination series and 34,441 newborns who were randomly assigned to the control group in which the participants received neither a vaccine nor a placebo.

Dramatic reduction of liver cancer incidence in young adults: 28 year follow-up of etiological interventions in an endemic area of China.

Qidong City, China, has had high liver cancer incidence from endemic hepatitis B virus (HBV) infection and dietary exposure to aflatoxin. Based on etiologic studies, we began interventions in 1980 to reduce dietary aflatoxin and initiate neonatal HBV vaccination. We studied trends in liver cancer incidence rates in the 1.

Therapeutic efficacy of trehalose eye drops for treatment of murine dry eye induced by an intelligently controlled environmental system.

Purpose: To determine whether eye drop instillation of the disaccharide trehalose (TT) alleviates ocular surface damage in a dry eye murine model.

Methods: Dry eye was induced in mice using an intelligently controlled environmental system (ICES). After 21 days housed in the ICES without topical treatment, the mice were randomly divided into three groups: no eye drops (ICES) for three weeks, four times a day with PBS 0.

[Risk features of HBV in human hepatocarcinogenesis: a nested case-controlled study].

Objective: To identify the association strength of the prevalence of HBeAg, covalently closed circular DNA (cccDNA) and 1762/1764 nucleotide mutations of hepatitis B virus (HBV) with the occurrence of hepatocellular carcinoma (HCC) in Qidong high risk male cohort.

Methods: A cohort of 377 middle aged HBV infected men in Qidong was followed from January 1989 to December 2002. Incident HCC cases were carefully registered.

Tight association of hepatocellular carcinoma with HBV infection in North China.

Background: Hepatocellular carcinoma (HCC) is the second most common cancer in China. Hepatitis B and C viruses (HBV and HCV) and aflatoxins are known risk factors for HCC, but the etiological status of these factors in HCC development is not clear. This study was undertaken to define the absolute importance of HBV in hepatocarcinogenesis of North China.

Dominant role of hepatitis B virus and cofactor role of aflatoxin in hepatocarcinogenesis in Qidong, China.

We assessed the separate and combined effects of hepatitis B virus (HBV), hepatitis C virus (HCV), and aflatoxin in causing hepatocellular carcinoma (HCC) in Qidong, China. A consecutive series of 181 pathologic-diagnosed HCC cases were studied for hepatitis B surface antigen (HBsAg), anti-HBc, HBV X gene sequence, anti-HCV, the 249ser-p53 mutation, and chronic hepatitis pathology. Each of the 181 incident HCC cases had markers for HBV infection and hepatitis pathology; only 6 of 119 cases were coinfected with HCV.
