OBJECTIVETo investigate clinical implications of expression of CD40L in monocytes and changes in serum soluble CD40L in patients with acute coronary syndromes (ACS).

METHODSSixteen control and 56 patients, including 24 with stable angina (SA), 20 with unstable angina (UA) and 12 with acute myocardial infarction (AMI) enrolled in this study. Expression of CD40L in monocytes was analyzed by flow cytometry and sCD40L levels were measured by ELISA.

RESULTSExpression of CD40L in monocytes and serum levels of sCD40L in UA and AMI patients were higher than in SA patients and controls. In patients with AMI, sCD40L levels showed no significant increase when compared to patients with UA, while AMI patients had a peak level of sCD40L at 24 hours after AMI. PTCA induced a marked rise in sCD40L levels in all patients, while CD40L expression in monocytes showed no difference between patients with PTCA, before and after.

CONCLUSIONEnhanced level of serum sCD40L may be a reliable prognostic indicator for ACS and may represent a marker of coronary disease activity.

Our study explored the dynamic changes in and the relationship between the DNA damage marker 8-hydroxy-2'-deoxyguanosine (8-OHdG) and the DNA repair marker 8-hydroxyguanine DNA glycosidase 1 (hOGG1) according to the length of occupational employment in nickel smelting workers. One hundred forty nickel-exposed smelting workers and 140 age-matched unexposed office workers were selected from the Jinchang cohort. The 8-OHdG levels in smelting workers was significantly higher than in office workers (Z=-8.688, P<0.05) and the 8-OHdG levels among nickel smelting workers in the 10-14 y employment length category was significantly higher than among all peers. The hOGG1 levels among smelting workers were significantly lower than those of non-exposed workers (Z=-8.948, P<0.05). There were significant differences between employment length and hOGG1 levels, with subjects employed in nickel smelting for 10-14 y showing the highest levels of hOGG1. Correlation analysis showed positive correlations between 8-OHdG and hOGG1 levels (r=0.413; P<0.01). DNA damage was increased with employment length among nickel smelting workers and was related to the inhibition of hOGG1 repair capacity.

Objective To employ high-throughput next generation sequencing (NGS) for analyzing the expression of lneRNAs and mRNAs in donor samples from pediatric living donor liver transplantation and search differentially expressed lncRNAs and drag metabolic gene for individualized guidance of immunosuppressive agents.Methods Between October 2016 and December 2017,10 liver tissue specimens from living donor liver transplantation children were collected and divided into fast and slow metabolic groups (n =5 each) according to the postoperative profiles of drug metabolism.Samples were assayed for high-throughput NGS.Target analysis was used for functional pathways and screening target genes prediction.Results There were differentially expressed 908 mRNAs and 1228 lncRNAs between slow metabolic and fast metabolic groups (P＜0.05).According to the abundance and difference,22 up-regulated and 18 down-regulated mRNAs,13 up-regulated and 24 down-regulated lncRNAs were selected.In addition to CYP3A5,CYP2C19,CYP1A2 and UGT1A1 might affect the metabolism of tacrolimus.At the same time,NONHSAT108617.2 in differemially expressed lncRNAs might regulate the expression of CYP3A5 gene.Conclusions This study has comprehensively analyzed the expression of lncRNAs in donor liver from pediatric liver transplantation.Some differentially expressed drug metabolism related genes may affect tacrolimus metabolism in vivo and thus the postoperative use of immunosuppressive drugs.

OBJECTIVETo describe the baseline data of cancers in the Jinchang Cohort, this paper examined trends in cancer mortality among adults investigated in Jinchang, Gansu province from 2001 to 2010.

METHODSMortality data were collected from company departments through administrative documents, death certificates, etc. Trend analyses of cancer mortality were performed on the basis of 925 cancer deaths between 2001 and 2010.

RESULTSThe crude mortality rate of cancer continuously increased from 161.86 per 100,000 in 2001 to 315.32 per 100,000 in 2010, with an average increase of 7.69% per year in the Jinchang Cohort (16.41% in females compared to 6.04% in males), but the age-standardized mortality rate increased only in females. Thirteen leading cancers accounted for 92.10% of all cancer deaths. The five leading causes of cancer mortality in males were lung, gastric, liver, esophageal, and colorectal cancer, whereas those in females were lung, liver, gastric, breast, and esophageal cancer.

CONCLUSIONThe overall cancer mortality rate increased from 2001 to 2010 in the Jinchang Cohort, with greater rate of increase in females than in males. Lung, breast, and gastric cancer, in that order, were the leading causes of increased cancer mortality in females.

Objective: To explore the association between fatty liver and type 2 diabetes mellitus (T2DM) in the baseline-population of Jinchang cohort study. Methods: Data from all the participants involved in the baseline-population of Jinchang cohort study was used, to compare the risks of T2DM in fatty liver and non fatty liver groups and to explore the interaction between family history or fatty liver of diabetes and the prevalence of T2DM. Results: Among all the 46 861 participants, 10 574 were diagnosed as having fatty liver (22.56%), with the standardized rate as 20.66%. Another 3 818 participants were diagnosed as having T2DM (8.15%) with standardized rate as 6.90%. The prevalence of T2DM increased in parallel with the increase of age (trend χ(2)=2 833.671, trend P<0.001). The prevalence of T2DM in the fatty liver group was significantly higher than that in the non-fatty liver group, both in men or women and in the overall population. Compared with the group of non-fatty liver, the risks of T2DM in fatty liver group were seen 1.78 times higher in males, 2.33 times in women and 2.10 times in the overall population, after adjustment for factors as age, levels of education, smoking, drinking, physical exercise, BMI, family history of diabetes and some metabolic indicators (pressure, TC, TG, uric acid, ALT, AST, gamma-glutamyl transferase). Date from the interaction model showed that fatty liver and family history of diabetes present a positive additive interaction on T2DM (RERI=1.18, 95%CI: 0.59-1.78; AP=0.24, 95%CI: 0.14-0.34; S=1.43, 95%CI: 1.21-1.69). Conclusions: Fatty liver could significantly increase the risk of T2DM and a positive additive interaction was also observed between fatty liver and family history of diabetes on T2DM. It was important to strengthen the prevention program on T2DM, in order to effectively control the development of fatty liver.

OBJECTIVETo understand the current status of the disease burden of liver cancer in Jinchang cohort.

METHODSAll the liver cancer death data from 2001 to 2013 and medical records of liver cancer cases from 2001 to 2010 in Jinchang cohort were collected for the analyses of the mortality, standardized mortality, potential years of life lost (PYLL) and working PYLL (WPYLL) associated with liver cancer. Spearman correlation and the average growth rate were used to analyze the trends.

RESULTSA total of 207 liver cancer deaths occurred in Jinchang cohort from 2001 to 2013, accounting for 16.68% of total cancer deaths. There were 259 liver cancer inpatients, accounting for 6.79% of the total cancer cases inpatients, in which 83 died (32.05%). Liver cancer death mainly occurred in males, accounting for 88.89%, and the liver cancer deaths in females accounted for 11.11%. The standardized mortality rate was 42.32/100,000 in males and 15.31/100,000 in females. The growth rate of liver cancer mortality was 5.62% from 2001 to 2013. Liver cancer deaths mainly occurred in age groups 60-69 years (26.57%) and 50-59 years (24.15%). The PYLL was 2906.76 person-years, the average PYLL was 14.04 years. The WPYLL was 1477.00 person-years and the average WPYLL was 7.14 years. The direct economic burden of liver cancer was 6270.78 Yuan per person, 301.75 Yuan per day. The average stay of hospitalization was 21.32 days.

CONCLUSIONThe mortality rate of liver cancer is increasing and the disease burden is still heavy.
