Du, Ling-Bin,Li, Hui-Zhang,Wang, Xiang-Hui,Zhu, Chen,Liu, Qing-Min,Li, Qi-Long,Li, Xue-Qin,Shen, Yong-Zhou,Zhang, Xin-Pei,Ying, Jiang-Wei,Yu, Chuan-Ding,Mao, Wei-Min Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.14
Objective: The Zhejiang Provincial Cancer Prevention and Control Office collected cancer registration data during 2000 to 2009 from 6 cancer registries in Zhejiang province of China in order to analyze the cancer incidence. Methods: Descriptive analysis included cancer incidence stratified by sex, age and cancer site group. The proportions and cumulative rates of 10 common cancers in different groups were also calculated. Chinese population census in 1982 and Segi's population were used for calculating age-standardized incidence rates. The log-linear model was used for fitting to calculate the incidence trends. Results: The 6 cancer registries in Zhejiang province in China covered a total of 60,087,888 person-years during 2000 to 2009 (males 30,445,904, females 29,641,984). The total number of new cancer cases were 163,104 (males 92,982, females 70,122). The morphology verified cases accounted for 69.7%, and the new cases verified only by information from death certification accounted for 1.23%. The crude incidence rate in Zhejiang cancer registration areas was $271.5/10^5$ during 2000 to 2009 (male $305.41/10^5$, female $236.58/10^5$), age-standardized incidence rates by Chinese standard population (ASIRC) and by world standard population (ASIRW) were $147.1/10^5$ and $188.2/10^5$, the cumulative incidence rate (aged from 0 to 74) being 21.7%. The crude incidence rate was $209.6/10^5$ in 2000, and it increased to $320.20/10^5$ in 2009 (52.8%), with an annual percent change (APC) of 4.51% (95% confidence interval, 3.25%-5.79%). Age-specific incidence rate of 80-84 age group was achieved at the highest point of the incidence curve. Overall with different age groups, the cancer incidences differed, the incidence of liver cancer being highest in 15-44 age group in males; the incidence of breast cancer was the highest in 15-64 age group in females; the incidences of lung cancer were the highest in both males and females over the age of 65 years. Conclusions: Lung cancer, digestive system malignancies and breast cancer are the most common cancers in Zhejiang province in China requiring an especial focus. The incidences of thyroid cancer, prostate cancer, cervical cancer and lymphoma have increased rapidly. Prevention and control measures should be implemented for these cancers.

Sirolimus and Non-melanoma Skin Cancer Prevention after Kidney Transplantation: A Meta-analysis
Gu, Yu-Hong,Du, Jia-Xin,Ma, Man-Ling Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.9
Background: Whether sirolimus is useful in the prevention of non-melanoma skin cancer (NMSC) remains unclear and we therefore performed this meta-analysis of randomized controlled trials to test the hypothesis that Sirolimus-based immunosuppression is associated with a decrease in NMSC. Methods: The main outcomes were NMSC, squamous-cell carcinoma and basal-cell carcinoma. The pooled risk ratio (RR) with its 95% confidence interval (95%CI) were used to assess the effects. Results: 5 randomized trials involving a total of 1499 patients receiving kidney transplantation were included. Patients undergoing Sirolimus-based immunosuppression had much lower risk of NMSC (RR = 0.49, 95%CI 0.32-0.76, P = 0.001). Subgroup analyses by tumor type showed that Sirolimus-based immunosuppression significantly decreased risk of both squamous-cell carcinoma (RR = 0.58, 95%CI 0.43-0.78, P < 0.001) and basal-cell carcinoma (RR = 0.56, 95%CI 0.37-0.85, P = 0.006). The quality of evidence was high for NMSC, and moderate for squamous-cell carcinoma and basal-cell carcinoma. No evidence of publication bias was observed. Conclusion: High quality evidence suggests that Sirolimus-based immunosuppression decreases risk of non-melanoma skin cancer, and Sirolimus has an antitumoral effect among kidney-transplant recipients.

Bacteriophage endolysin is one of the most promising antibioticsubstitutes, but in Gram-negative bacteria, the outermembrane prevents the lysin from hydrolyzing peptidoglycansand blocks the development of lysin applications. Theprime strategy for new antibiotic substitutes is allowing lysinto access the peptidoglycan from outside of the bacteria byreformation of the lysin. In this study, the novel Escherichiacoli (E. coli) phage lyase lysep3, which lacks outside-in catalyticability, was fused with the N-terminal region of theBacillus amyloliquefaciens lysin including its cell wall bindingdomain D8 through the best manner of protein fusionbased on the predicted tertiary structure of lysep3-D8 to obtainan engineered lysin that can lyse bacteria from the outside. Our results showed that lysep3-D8 could lyse both Gramnegativeand Gram-positive bacteria, whereas lysep3 and D8have no impact on bacterial growth. The MIC of lysep3-D8on E. coli CVCC1418 is 60 μg/ml; lysep3-D8 can inhibit thegrowth of bacteria up to 12 h at this concentration. The bactericidalspectrum of lysep3-D8 is broad, as it can lyse of allof 14 E. coli strains, 3 P. aeruginosa strains, 1 Acinetobacterbaumannii strain, and 1 Streptococcus strain. Lysep3-D8 hassufficient bactericidal effects on the 14 E. coli strains testedat the concentration of 100 μg/ml. The cell wall binding domainof the engineered lysin can destroy the integrity of theouter membrane of bacteria, thus allowing the catalytic domainto reach its target, peptidoglycan, to lyse the bacteria. Lysep3-D8 can be used as a preservative in fodder to benefitthe health of animals. The method we used here proved to bea successful exploration of the reformation of phage lysin.

The main purpose of this study was to investigate whether type 3 muscarinic acetylcholine receptor (M3R) dysfunction induced vascular hyperpermeability. Transwell system analysis showed that M3R inhibition by selective antagonist 4-diphenylacetoxy-N-methylpiperidine methiodide (4-DAMP) and small interfering RNA both increased endothelial permeability. Using coimmunoprecipitation and Western blot assay, we found that M3R inhibition increased VE-cadherin and β-catenin tyrosine phosphorylation without affecting their expression. Using PTP1B siRNA, we found that PTP1B was required for maintaining VE-cadherin and β-catenin protein dephosphorylation. In addition, 4-DAMP suppressed PTP1B activity by reducing cyclic adenosine monophosphate (cAMP), but not protein kinase C (PKCa). These data indicate that M3R preserves the endothelial barrier function through a mechanism potentially maintaining PTP1B activity, keeping the adherens junction proteins (AJPs) dephosphorylation.
