OBJECTIVES: Proper blood lipid levels are essential for survival in older adults, but inconsistent relationships have been reported between blood lipids and all-cause mortality in the elderly. METHODS: This retrospective longitudinal study analyzed data from 1,067 Chinese older adults enrolled in the Chinese Longitudinal Healthy Longevity Survey collected in 2008 and followed up until death or December 31, 2018. The outcome was allcause mortality. Multivariate Cox regression analyses were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) with stratification by age (60-80, 80-100, or ≥ 100 years) for further analysis. The survival probability according to lipid profile quartiles was calculated using Kaplan-Meier curves and the log-rank test. RESULTS: The participants’ mean age was 84.84 years, and 57.0% were female. In total, 578 individuals died, and 277 were lost to follow-up. The mean total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) levels were higher among those who died than among those who survived. Participants in the second HDL-C quartile and the highest LDL-C and triglyceride (TG) quartiles had 28% higher, 23% lower, and 49% lower risks of all-cause mortality, respectively. After further adjustment, the associations remained except for HDL-C, and additional associations were observed between all-cause mortality and the third TC and LDL-C quartiles and the second TG quartile (HR, 1.44; 95% CI, 1.01 to 2.06; HR, 0.68; 95% CI, 0.49 to 0.94; HR, 0.79; 95% CI, 0.62 to 0.99, respectively). CONCLUSIONS: Older adults should maintain an LDL-C level of 1.91-2.47 mmol/L and a TG level of no less than 1.66 mmol/L.

Wang, Ying-Xin,Fan, Kai,Tao, Ding-Bo,Dong, Xiang Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.10
Background: Gliomas are the most common type of primary brain tumor in adults, and the X-ray repair complementing group 1 gene (XRCC1) is an important candidate gene influencing its risk. The objective of this study was to detect the influence of XRCC1 genetic polymorphisms on glioma risk. Materials and Methods: A total of 629 glioma patients and 641 cancer-free subjects were enrolled in this case-control study. The genotypes of the c.1471G>A genetic polymorphism were determined by created restriction site-polymerase chain reaction (CRS-PCR) and DNA sequencing methods. The influence of the XRCC1 genetic polymorphism on glioma risk was evaluated by association analysis. Results: Our data indicated that the alleles/genotype of this genetic variant was statistically associated with glioma risk. The AA genotype was statistically associated with the increased risk of glioma compared to the GG wild genotype (odds ratios (OR) = 1.89, 95% CI 1.25-2.87, P = 0.003). The allele-A may contribute to increased the susceptibility to glioma (OR = 1.23, 95% CI 1.04-1.46, P = 0.017). Conclusions: These preliminary findings indicate that the c.1471G>A genetic polymorphism of XRCC1 has the potential to influence glioma susceptibility, and might be used as molecular marker for assessing glioma risk.

Wang, Na-Na,Xu, Yong,Yang, Kuo,Wei, Dong,Zhang, Yao-Guang,Liu, Ming,Shi, Xiao-Hong,Liang, Si-Ying,Sun, Liang,Zhu, Xiao-Quan,Yang, Yi-Ge,Tang, Lei,Zhao, Cheng-Xiao,Wang, Xin,Chen, Xin,Hui, Juan,Zhang, Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.5
Background: KLK3 gene products, like human prostate-specific antigen (PSA), are important biomarkers in the clinical diagnosis of prostate cancer (PCa). G protein-coupled receptor RFX6, C2orf43 and FOXP4 signaling plays important roles in the development of PCa. However, associations of these genes with PCa in northern Chinese men remain to be detailed. This study aimed to investigate their impact on occurrence and level of malignancy. Methods: All subjects were from Beijing and Tianjin, including 266 cases with prostate cancer and 288 normal individuals as controls. We evaluated associations between clinical covariates (age at diagnosis, prostate specific antigen, Gleason score, tumor stage and aggressive) and 6 candidate PCa risk loci, genotyped by PCR- high resolution melting curve and sequencing methods. Results: Case-control analysis of allelic frequency of PCa associated with PCa showed that one of the 6 candidate risk loci, rs339331 in the RFX6 gene, was associated with reduced risk of prostate cancer (odds ratio (OR) = 0.73, 95% confidence interval (CI) =0.57-0.94, P = 0.013) in northern Chinese men. In addition, subjects with CX (CC+TC) genotypes had a decreased risk for prostrate cancer compared to those carrying the TT homozygote (OR =0.64, 95% CI = 0.45- 0.90, P = 0.008). The TT genotype of 13q22 (rs9600079, T) was associated with tumor stage (P=0.044, OR=2.34, 95% CI=0.94-5.87). Other SNPs were not significantly associated with clinical covariates in prostate cancer (P > 0.05). Conclusions. rs339331 in the RFX6 gene may be associated with prostate cancer as a susceptibility locus in northern Chinese men.

A prerequisite for using isotopic techniques to study the regional water cycle of a mountainous area is to examine the stable isotopic composition of precipitation. These findings are of great significance for an in-depth understanding of water cycle processes. In this study, each precipitation event was sampled and used to investigate the characteristics of stable hydrogen and oxygen isotopes in precipitation over the Jiaolai Plain and its surrounding areas. NCEP/NCAR data was used for the wind speed and direction, relative humidity, and precipitable amount in the study area during the sampling period. The water vapor sources of the precipitation over the plain were revealed through a comparative analysis of seasonal variations in precipitation isotopes between Global Network of Isotopes in Precipitation stations located along different vapor transport paths. The results showed that the local meteoric water line was δ2H = 6.38 δ18O + 0.72, with a gradient of less than 8. This indicates that the precipitation process was affected by non-equilibrium evaporation occurring when the drops fell below the cloud base. Temperature and amount effects were observed in the δ18O of the precipitation, although the altitude effect was not significant. The water vapor source of the precipitation was predominantly controlled by the East Asian Monsoon from June to September, with the primary source being evaporation from the adjacent Pacific Ocean. The plain was controlled by the Westerlies from October through May, with the predominant vapor source being local evaporation. Water vapor from the polar region had a minimal impact. These findings can serve as the basis for studying surface water–groundwater–seawater transformations.

Background Deubiquitinating enzymes (DUBs) have been shown to be possible targets for hepatocellular carcinoma (HCC) treatment. Objective This study was designed to reveal the effect and underlying mechanism of Josephin-2, a relatively newly defined DUB, in HCC progression. Methods SNU-387 and PLC/PRF/5 cells were used for in vitro functional assays. The levels of Josephin-2 and phosphoglycerate dehydrogenase (PHGDH) were determined using RT-qPCR and western blotting. Cell proliferation, migration and invasion were assessed by CCK-8, colony formation and Transwell. Spheroid-forming assay was performed to assess the cancer stem cell (CSC)-phenotype of HCC cells. A xenograft mice model was applied to verify the effect of Josephin-2 on HCC cell growth in vivo. Results Herein, we showed that Josephin-2 expression was negatively correlated with HCC patient survival in data from the online database. Cell experiments indicated that knockdown of Josephin-2 attenuated HCC cell malignant biological behaviors. Besides, Josephin-2 silencing also decreased the spheroid-formation while inhibited the expression of CSC biomarkers (CD133, OCT4, SOX2 and EpCAM) in HCC cells. Mechanistically, Josephin-2 had a deubiquitinating activity towards the regulation of PHGDH protein, the rate-limiting enzyme in the first step of serine biosynthesis pathway. Depletion of Josephin-2 enhanced the ubiquitination degradation of PHGDH and ultimately inhibited the proliferation and CSC-phenotype of HCC in vitro and in vivo. Conclusion Our work uncovered the regulatory effects of Josephin-2 on PHGDH protein stability and profiled its contribution in HCC malignant progression, which might provide a potential therapeutic target for HCC.

Wang, Jian-Tao,Chang, Li-Ming,Song, Xin,Zhao, Li-Xin,Li, Jun-Tao,Zhang, Wei-Guo,Ji, Ying-Bin,Cai, Li-Na,Di, Wei,Yang, Xin-Yu Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.22
Purpose: To compare tumor size by mammography and sonography and align with pathological results in primary breast cancer cases. Materials and Methods: We retrospectively reviewed 95 primary breast cancer patients who underwent mammography and sonography from January 2011 to June 2012. The largest tumor diameter was chosen as sizing reference for each imaging modality. The measurements of mammography and sonography were considered concordant if they were within the measurement of pathological results ${\pm}0.5cm$. Pearson's correlation coefficient was calculated for imaging results. Results: The range of the maximum diameter was 0.6cm-10.5cm and mean value was $3.81{\pm}2.04cm$ by pathological results, 0.7cm-12.4 cm and $3.99{\pm}2.19cm$ by mammography, and 0.9cm-11.0cm and $3.63{\pm}2.01cm$ by sonography, respectively. Sonography (R: 0.754), underestimated tumor size, but had a better correlation with pathological tumor size compared to mammography (R: 0.676), which overestimated tumor size. Conclusions: Sonography is superior to mammography in assessment of primary breast cancer.

Inhibitory effects of piceatannol on human cytomegalovirus (hCMV) in vitro
Wang San-Ying,Zhang Jing,Xu Xiao-Gang,Su Hui-Li,Xing Wen-Min,Zhang Zhong-Shan,Jin Wei-Hua,Dai Ji-Huan,Wang Ya-Zhen,He Xin-Yue,Sun Chuan,Yan Jing,Mao Gen-Xiang 한국미생물학회 2020 The journal of microbiology Vol.58 No.8
Human cytomegalovirus (hCMV) is a ubiquitous herpesvirus, which results in the establishment of a latent infection that persists throughout the life of the host and can be reactivated when the immunity is low. Currently, there is no vaccine for hCMV infection, and the licensed antiviral drugs mainly target the viral enzymes and have obvious adverse reactions. Thus, it is important to search for compounds with antihCMV properties. The present study aimed to investigate the suppressive effects of piceatannol on hCMV Towne strain infection and the putative underlying mechanisms using human diploid fibroblast WI-38 cells. Piceatannol supplementation prevented the lytic changes induced by hCMV infection in WI-38 cells. Furthermore, piceatannol suppressed the expression of hCMV immediate-early (IE) and early (E) proteins as well as the replication of hCMV DNA in a dose-dependent manner. Moreover, hCMV-induced cellular senescence was suppressed by piceatannol, as shown by a decline in the senescence-associated β-galactosidase (SA-β-Gal) activity and decreased production of intracellular reactive oxygen species (ROS). p16INK4a, a major senescence-associated molecule, was dramatically elevated by current hCMV infection that was attenuated by pre-incubation with piceatannol in a dose-dependent manner. These results demonstrated that piceatannol suppressed the hCMV infection via inhibition of the activation of p16INK4a and cellular senescence induced by hCMV. Together, these findings indicate piceatannol as a novel and potent anti-hCMV agent with the potential to be developed as an effective treatment for chronic hCMV infection.
