Adiponectin secreted by adipose tissue has been implicated in prostate carcinogenesis. Genetic variations in ADIPOQare thought to influence the activity of adiponectin, thus relating to cancer occurrence. In this hospital-based case-control study of 917 prostate cancer （PCa） cases and 1036 cancer-free controls, we evaluated the association of single nucleotide polymorphisms in ADIPOQ with risk of PCa and adiponectin levels in Chinese Han men. Variants of ADIPOQ were genotyped by Taqman polymerase chain reaction method. The plasma adiponectin concentrations were measured by *** immunosorbent assay （ELISA） in a subset of cases and controls. We found that the ADIPOQ rs3774262 variant AA genotype was associated with both decreased PCa risk [adjusted odds ratio （OR）： 0.66, 95% confidence interval （CI） =0.48-0.92] and increased plasma adiponectin levels （P= 0.036 and 0,043）, with significant difference by tumor grade, clinical stage, and aggressiveness. A significant interaction between ADIPOQ rs3774262 and body mass index was observed in modifying the risk of PCa （P=6.7 × 10-3）. ADIPOQ rs266729 and rs182052 were not related to PCa risk or plasma adiponectin levels. Our data support that ADIPOQ rs3774262 may affect PCa risk in combination with plasma adiponectin levels in Chinese Han men. It may contribute to the molecular basis for the association between obesity and PCa.

The association between metabolic syndrome and advanced prostate cancer in Chinese patients receiving radical prostatectomy

引用

Asian Journal of Andrology 2015年第5期17卷 839-844,I0011页

作者： gui-Ming Zhang Yao Zhu Da-Hai Dong cheng-Tao Han cheng-yuan gu Wei-Jie gu Xiao-Jian Qin Li-Jiang Sun Ding-Wei Ye Department of Urology Fudan University Shanghai Cancer Center Shanghai China Department of Oncology Shanghai Medical College Fudan University Shanghai China Department of Urology The Affiliated Hospital of Qingdao University Qingdao Shandong China

The global incidence of metabolic syndrome （MetS） is dramatically increasing. Considerable interest has been devoted to the relationship between MetS and prostate cancer （PCa） risk. However, few studies have examined the association between MetS and PCa progression. This retrospective study consisted of 1016 patients with PCa who received radical prostatectomy. The association between MetS and pathological features was evaluated using logistic regression analysis. Compared with patients without MetS, those with MetS indicated an increased risk of prostatectomy Gleason score （GS）≥8 （odds ratio [OR] =1.670, 95% confidence interval （CI） 1.096-2.545, P = 0.017）, and a 1.5-fold increased risk of pT3-4 disease （OR = 1.583, 95% CI 1.106-2.266, P = 0.012）. The presence of MetS was an independent predictor of lymph node involvement （OR = 1.751, 95% CI 1.038-2.955, P = 0.036）. Furthermore, as the number of MetS components accumulated, the risk of a GS ≥ 8 increased. The present study indicates a significant association between MetS and advanced PCa. The results need to be evaluated in large-scale prospective cohorts.

Parameter selection for the hydroconversion of waste polyethylene plastic under mild conditions: A comprehensive evaluation

The hydrogenolysis/hydrocracking of waste polyethylene(PE) has recently been intensively studied, with the general pursuit of low-temperature reaction conditions, increased oil-phase yield, and narrower carbon chain distribution. Before this, we utilized a ball-milled ZSM-22 catalyst loaded with Ru nanoparticles(NPs), which exhibited excellent hydroconversion performance. It deconstructed PE into >80 wt.% oil products under low temperatures and short reaction times. Herein, we investigated the influence of varying temperature/pressure parameters on the degree of specific hydrocracking/internal hydrogenolysis/terminal hydrogenolysis reactions. From the comprehensive energy efficiency perspective, including stirring, reaction, and product separation, as well as taking into account the degree of product isomerization and catalyst lifespan, we analyzed the optimization of parameters. This research abandons the notion that lower temperatures are better and proposes a more comprehensive evaluation framework for low-consumption hydroconversion of PE to produce high-value products.

Serum lipid profiles： novel biomarkers predicting advanced prostate cancer in patients receiving radical prostatectomy

引用

Asian Journal of Andrology 2015年第2期17卷 239-244,I0008页

作者： gui-Ming Zhang Xiao-Jian Qin Hai-Liang Zhang Wen-Jun Xiao Yao Zhu cheng-yuan gu Bo Dai guo-Hai Shi Ding-Wei Ye Department of Urology Fudan University Shanghai Cancer Center Shanghai China Department of Oncology Shanghai Medical College Fudan University Shanghai China.

This study aimed to evaluate the role of serum lipid profiles as novel biomarkers in predicting pathological characteristics of prostate cancer （PCa）. We retrospectively analyzed 322 consecutive patients with clinically localized PCa receiving radical prostatectomy （RP） and extended pelvic lymphadenectomy. Unconditional logistic regression was used to estimate the prostatectomy Gleason score （pGS）, pathological stage and lymph node involvement （LNI） in RP specimens. Preoperative prostate-specific antigen （PSA） levels, biopsy GS （bGS）, and preoperative tumor, node, metastasis staging were used as basic variables to predict postoperative pathological characteristics. Preoperative serum lipid profiles were introduced as potential predictors. A receiver operating characteristic （ROC） curve was used to determine predictive efficacy. Significant differences in pathological characteristics were observed among patients with normal and abnormal total cholesterol （TC）, triglyceride （TG）, and low-density lipoprotein （LDL） levels, with the exception of pGS in the TG group. Multivariable regression analysis revealed that the odds ratio for high levels of TC for LNI compared with normal TC levels was 6.386 （95% confidence interval [Cl] 1.510-27.010）, 3.270 （95% CI. 1.470-7.278） for high levels of TG for pT3-4 disease, and 2.670 （95% Ch 1.134-6.287） for high levels of LDL for pGS. The area under the ROC curve of the models with dyslipidemia was larger than that in models without dyslipidemia, in predicting pathological characteristics. Abnormal TC, TG, and LDL levels are significantly associated with postoperative pathological status in PCa patients. Together with preoperative PSA levels, bGS, and clinical stage, dyslipidemia is more accurate in predicting pathological characteristics.
