A multi-center study on cost-effectiveness of prevention and control of ventilator-associated pneumonia in tertiary comprehensive hospitals in Jiangsu Province / 中国感染控制杂志

Objective To explore the cost-effectiveness of infection prevention and control of ventilator-associated pneumonia(VAP).Methods 12 hospitals in Jiangsu Province were chosen, a1∶1 matched case-control multicenter study was adopted.The rate difference was calculated by Meta analysis.Results A total of 255 cases and controls were enrolled in this study.The study found that each VAP patient had to spend additional 103 799.00 yuan, stay in ICU for extra 11.72 days, and in hospital for extra 15.53 days.On the basis of the price index of different years, compared with 2014, 2015 saved 36 million yuan for patients.Prevention of one case of VAP in ICU could treat 0.76 more new patients.The hospital revenue was 24 464 560.5 yuan in2015.The total direct economic benefits of hospitals and patients were 60 883 996.6 yuan.Conclusion Prevention and control of HAI is one of the medical ontology connotation, it can greatly reduce the economic burden of patients, save economic cost, create benefits and enhance the image for hospital, and achieve a triple win situation for"patients-hospital-society".

Study on the association between total plasma homocysteine levels, dietary habits and the risk of gastric cancer / 中华流行病学杂志

<p><b>OBJECTIVE</b>To explore the relationship between total plasma homocysteine (tHcy) levels, dietary habits and susceptibility of gastric cancer (CGC) in Yangzhong and Yixing cities, the two high GC risk areas in Jiangsu province.</p><p><b>METHODS</b>A population-based case-control study was conducted including 391 histologically-confirmed adenocarcinoma GC cases and 608 age and sex frequency-matched cancer-free controls. The plasma tHcy concentration was measured by enzymatic biochemical assay of homocysteine on microtiter plates, using crude lysate containing recombinant methionine 7-lyase. The relationship between different tHcy levels and risk of GC was analyzed and factors as vegetables and fruits intake, smoking and drinking status were also evaluated together with tHey levels on the risk of GC.</p><p><b>RESULTS</b>The average tHcy levels in GC cases were significantly higher than that in controls (P = 0.002). In addition, according to the quartile levels (7.9, 10.1, 13.7 micromol/L) in the controls, the risks of GC had an increase of 67% (adjusted OR = 1.67, 95% CI: 1.12-2.48), 98% (adjusted OR = 1.98, 95% CI: 1.33-2.94) and 112% (adjusted OR = 2.12, 95% CI: 1.44-3.15) compared to the lowest quartile of tHcy (< or = 7.9 micromol/L), respectively while the increasing trend was significantly noticed (chi2 = 15.78, P < 0.001). The increase of vegetables and fruits intake could decrease the risk of GC. Results from crossover analyses indicated that subjects with less vegetables and fruits intake or both smoking drinking together with plasma tHcy >15.0 micromol/L could increase the GC risk, when compared to the effect on GC risk of each factor.</p><p><b>CONCLUSION</b>These findings supported the hypothesis that the high level of plasma tHcy and the badness dietary habits were associated to the increased risk of GC. Further larger scale and genetics involved studies on the environment and genetic factors were needed to confirm our findings.</p>

The association of polymorphisms of CDT1 and GMNN gene with the risk of breast cancer in Chinese women: a case-control analysis / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To investigate the association of polymorphisms of CDT1 and GMNN gene, two important genes participating in DNA replication, with the risk of sporadic breast cancer.</p><p><b>METHODS</b>Using polymerase chain reaction-restriction fragment length polymorphism (PCR - RFLP) and the primer-introduced restriction analysis (PIRA)-PCR assay to genotype the CDT1 838G/A and GMNN 387C/A polymorphisms in a case-control study of 427 breast cancer cases and 477 cancer-free controls in a Chinese population.</p><p><b>RESULTS</b>No significant association of the CDT1 838G/A and GMNN 387C/A polymorphisms with the risk of breast cancer was found (adjusted OR:1.16, 95% CI:0.88-1.54 for CDT1 GA+AA genotypes and adjusted OR:0.90, 95% CI:0.67-1.21 for GMNN CA+AA genotypes). However, in the stratified analyses, a significant association of CDT1 GA+AA genotypes with breast cancer risk among subjects with family history of cancer was found (adjusted OR:2.21, 95% CI:1.20-4.09).</p><p><b>CONCLUSION</b>These findings suggest that the CDT1 838G/A and GMNN 387C/A polymorphisms may not play a major role in the etiology of breast cancer, but CDT1 variant may have a potential role only in genetically susceptible women.</p>

Association between functional genetic polymorphisms of IL-1B and IL-1RN and susceptibility to gastric cancers / 上海第二医科大学学报

Objective To study the association between functional genetic polymorphisms of IL-1B(T-31C,C-511T),IL-1RN and the susceptibility to gastric cancers. Methods A case-control study was conducted in 180 gastric cancer cases and 308 age-and sex-matched cancer-free controls.Genotypes were detected by PCR-restriction fragment length polymorphism(PCR-RFLP) assays,and association between genotypes,environmental factors and risk of gastric cancers were determined. Results IL-1B T-31C was in strong linkage disequilibrium with IL-1B C-511T(D'=0.862,R2= 0.721,P=0.000).Multivariate logistic regression analysis revealed that the variant genotypes of IL-1B T-31C and C-511T were not significantly associated with risks for gastric cancers(adjusted OR,0.95 and 95% CI,0.62-1.47 for IL-1B T-31C;and adjusted OR,0.85 and 95% CI,0.55-1.31 for IL-1B C-511T).The variant genotypes(1/2,2/2) in IL-1RN were associated with a non-significantly increased risks for gastric cancers(adjusted OR,1.32 and 95% CI,0.71-2.36) in all subjects and with a significantly increased risks for gastric cancers in subjects with H.pylori infection(adjusted OR,2.03 and 95%CI,1.02-4.80).Conclusion The functional genetic polymorphisms of IL-1RN may contribute to the risks of gastric cancers in high-risk population,particularly in those with H.pylori infection.
