Associations between hepatitis B virus exposure and the risk of extrahepatic digestive system cancers: A hospital-based, case-control study (SIGES).

Objectives: This case-control study was aimed to investigate associations between HBV infection and extrahepatic digestive system cancers.

Methods: The patients of gastric, small intestinal, colonic, rectal, anal, biliary tract, and pancreatic cancers were retrospectively collected between 2016.5 and 2017.

Gamma-glutamyl transpeptidase-to-platelet ratio and the fibrosis-4 index in predicting hepatitis B virus-related hepatocellular carcinoma development in elderly chronic hepatitis B patients in China: A single-center retrospective study.

Gamma-glutamyl transpeptidase-to-platelet ratio (GPR) and fibrosis-4 (FIB-4) index have been reported to be useful predictors in predicting hepatocellular carcinoma (HCC) development in chronic hepatitis B (CHB) patients. However, their predictive performances on HCC development have not been validated in elderly patients. Thus, the aim of this study was to evaluate the predictive values of the GPR and FIB-4 index on HCC in elderly CHB patients with in China.

The risk of stroke and associated risk factors in a health examination population: A cross-sectional study.

Health examination is an important method for early detection of people with different risk of stroke. This study estimates the risk of stroke and identify risk factors for people who underwent health examinations at the Health Examination Center at West China Hospital, Sichuan University from July 2014 to February 2018.A total of 31,464 people were recruited in this study and divided into 3 groups (low risk, moderate risk, and high risk) according to risk of stroke.

Multiple sclerosis and stroke: a systematic review and meta-analysis.

Background: Multiple sclerosis (MS) and stroke are two common causes of death and disability worldwide. The relationship between these two diseases remains unclear. Effective early preventative measures and treatments are available to reduce the morbidity and mortality of acute stroke.

[Clinical Research on the Post-operative Hemodynamics Changes in Donors after Living Donor Liver Transplantation].

Objective: To investigate the postoperative hemodynamics changes and their influence factors in the donors after right lobe living donor liver transplantation.

Methods: A total of 53 consecutive living donors from Dec 2010 to Aug 2015 who underwent donor right lobe hepatectomy were retrospectively analyzed. We measured residual liver hemodynamics with color doppler ultrasound, detected liver stiffness by transient elastography, also analyzed postoperative liver function, hemodynamics, and the long term variation tendency of hepatocirrhosis and spleen.

[Component Changes of Metabolic Syndrome in Pre-elderly People with Healthy Obese Phenotype].

Objective: To determine component changes of metabolic syndrome in pre-elderly people with healthy obese phenotype.

Methods: A total of 1 686 adults aged between 45-59 yr. who underwent health examinations from 2010 to 2016 in West China Hospital of Sichuan University participated in this study.

[Helicobacter pylori infection and associated risk factors in Chengdu].

Objective: To investigate the prevalence of Helicobacter pylori (Hp) infection in Chengdu and its risk factors.

Methods: Permanent residents in Chengdu who took routine health examinations in the West China Hospital of Sichuan University were recruited in the study. All participants received 14C-urea breath test (14C-UBT) for the diagnosis of Hp infection.

[Association of chronic obstructive pulmonary disease and lung cancer].

Objective: To investigate the association between chronic obstructive pulmonary disease (COPD) and lung cancer.

Methods: A case-control study was undertaken, with 180 cases of lung cancer and 200 cases of controls.

Results: The odd of lung cancer was higher in patients with COPD, emphysema, chronic bronchitis, and pulmonary tuberculosis (P < 0.
