Type 2 diabetes and hepatocellular carcinoma: a case-control study in patients with chronic hepatitis B.

Type 2 diabetes has been suggested as an independent risk factor for the development of hepatocellular carcinoma (HCC). However, the role of Type 2 diabetes on the development of HCC in the presence of chronic hepatitis B (CHB) remains inconclusive. We conducted this hospital-based case-control study to evaluate the roles of Type 2 diabetes in HCC development in patients with CHB. From January 2004 to December 2008, a total of 6,275 eligible consecutive patients with chronic hepatitis B virus (HBV) infection were recruited. A total of 1,105 of them were patients with HBV-related HCC and 5,170 patients were CHB but without HCC. We used multivariate logistic regression models to investigate the association between Type 2 diabetes and HCC risk. The prevalence of Type 2 diabetes is higher among HCC patients without cirrhosis than among those with cirrhosis (12.1% vs. 6.7%, p=0.003). Type 2 diabetes was associated with a significantly high risk of HCC in female patients after adjusting for age, family history of HCC, city of residence, hepatitis B e antigen and cirrhosis with an odds ratio (95% confidence interval, CI) of 1.9 (1.1-3.4). Restricted analyses among female patients without cirrhosis indicated that Type 2 diabetes was strongly associated with HCC risk with adjusted odds ratio (95% CI) of 5.6 (2.2-14.1). In conclusion, Type 2 diabetes is independently associated with the increased risk of HCC in female CHB patients. Female CHB patients with Type 2 diabetes are of a high HCC risk population and should be considered for HCC close surveillance program.

Spatiotemporal patterns of anuran functional diversity in temperate montane forests.

Functional diversity is an integrative approach to better understand biodiversity across space and time. In the present study, we investigated the spatiotemporal patterns (i.e., elevation and season) and environmental determinants of anuran functional diversity on Tianping Mountain, northwest Hunan, China. Specifically, 10 transects were established from low (300 m a.s.l.) to high (1 492 m a.s.l.) elevations, and anuran communities were sampled in spring, early summer, midsummer, and autumn in 2017. Four functional diversity indices were computed for each transect in each season using ecomorphological functional traits. Our results demonstrated that these indices had contrasting responses to increasing elevations. However, they did not differ significantly among seasons in terms of temporal patterns. Interestingly, the unique spatiotemporal functional diversity patterns were impacted by distinct environmental variables, such as leaf litter cover, water temperature, number of trees, and water conductivity.

Hazardous alcohol consumption and aging synergistically increase the risk of death in patients with severe fever with thrombocytopenia syndrome.

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease with high case fatality rate (CFR). Alcohol consumption which impairs host immunity and contributes to tissue damage in a variety of organs may be a predisposing factor of fatal outcome in SFTS. We aimed to determine the role of alcohol consumption on the fatal outcome of SFTS. Patients with laboratory-diagnosed SFTS who were admitted to the Jinan Infectious Disease Hospital, Jinan, China, between January 2011 and November 2018 were evaluated. Demographic, clinical, and laboratory data were recorded. Alcohol consumption was evaluated. The association between a fatal outcome and each demographic, clinical, and laboratory variable with alcohol consumption was assessed. A total of 694 patients with SFTS were identified during the study period. The overall CFR was 20.9 % (95 % CI: 17.9 %-23.9 %). The CFR in non/light drinkers (0-98 g/week) and moderate/heavy drinkers (>98 g/week) was 18.3 % and 35.6 %, respectively (P < 0.001). In age>60 years patients, the overall CFR in moderate/heavy drinker groups were as high as 53.4 % (95 % CI:40.2 %-66.7 %). Comparing to the age≤60y and non/light drinkers, age>60y and moderate/heavy drinkers was associated with increased risk of death with an odds ratio (95 % CI) of 9.9 (5.1-19.1). The interaction between age>60 and alcohol consumption was a significant determinant for death in both genders (F=10.18, P = 0.001). The clinical manifestation, laboratory parameters, and organ injury were significantly extensive and severe in moderate and heavy drinkers. In conclusion, hazardous alcohol consumption and aging synergistically increase the risk of death in patients with SFTS. In SFTS endemic areas, it is important for older individuals to minimize the exposure risks and abstain from alcohol.

ABO blood group and the risk of hepatocellular carcinoma: a case-control study in patients with chronic hepatitis B.

BACKGROUND: Studies have observed an association between the ABO blood group and risk of certain malignancies. However, no studies of the association with hepatocellular carcinoma (HCC) risk are available. We conducted this hospital-based case-control study to examine the association with HCC in patients with chronic hepatitis B (CHB). METHODS: From January 2004 to December 2008, a total of 6275 consecutive eligible patients with chronic hepatitis B virus (HBV) infection were recruited. 1105 of them were patients with HBV-related HCC and 5,170 patients were CHB without HCC. Multivariate logistic regression models were used to investigate the association between the ABO blood group and HCC risk. RESULTS: Compared with subjects with blood type O, the adjusted odds ratio (AOR) for the association of those with blood type A and HCC risk was 1.39 [95% confidence interval (CI), 1.05-1.83] after adjusting for age, sex, type 2 diabetes, cirrhosis, hepatitis B e antigen, and HBV DNA. The associations were only statistically significant [AOR (95%CI) = 1.56(1.14-2.13)] for men, for being hepatitis B e antigen positive [AOR (95%CI) = 4.92(2.83-8.57)], for those with cirrhosis [AOR (95%CI), 1.57(1.12-2.20)], and for those with HBV DNA≤10(5)copies/mL [AOR (95%CI), 1.58(1.04-2.42)]. Stratified analysis by sex indicated that compared with those with blood type O, those with blood type B also had a significantly high risk of HCC among men, whereas, those with blood type AB or B had a low risk of HCC among women. CONCLUSIONS: The ABO blood type was associated with the risk of HCC in Chinese patients with CHB. The association was gender-related.

[Clinical observation on strong stimulation of acupoints around eyes for treatment of adolescent myopia].

OBJECTIVE: To observe the therapeutic effect and influential factors of strong stimulation of acupoints around eyes by reducing method of twisting the needle for treatment of adolescent myopia, and to compare the different curative effects of both weak and strong stimulus intensities and wearing glasses in daytime. METHODS: According to the principle of knowing and permission, the patients were divided into a strong stimulation group (60 cases, 120 eyes), a weak stimulation group (60 cases, 120 eyes) and a wearing glasses group (60 cases, 120 eyes). Both the strong stimulation group and the weak stimulation group were treated by reducing method of twisting the needle, with Cuanzhu (BL 2), Yuyao (EX-HN 4), Sizhukong (TE 23), Sibai (ST 2) and Taiyang (EX-HN 5) selected. Each acupoint was twisted 360 and 90 times per min for the strong stimulation group, and 90 degrees and 60 times per min for the weak stimulation group; the wearing glasses group were not treated with acupuncture, but with wearing glasses in daytime. RESULTS: After treatment with the reducing method of twisting the needle, the vision improved (P < 0.01), with more obviously increased in the strong stimulation group than the weak stimulation group (P < 0.01), and there was no significant change of vision in the wearing glasses group. The age and the myopic degree of the patient before treatment were closely related with the change of vision after treatment (P < 0.01). CONCLUSION: The reducing method of twisting the needle has a definite clinical therapeutic effect on adolescent myopia; strong stimulation has a better effect than the weak one; the age and the myopic degree of the patient possibly influence the therapeutic effect.
