Objectives:In order to prevent and control hospital infection efficiently, comprehensive management is put into effect on the quality of disinfectant and sterilization. Methods:The management model which spot-supervision, bacteria monitor and scientific modification are integrated has been applied in hospital. Results and Conclusions:The sterilization mind of staffs has been steadily strengthened and the qualified ratios of various monitor items has increased annually.

Objective To investigate the relationship between red blood cell distribution width (RDW) and prognosis in patients with multiple myeloma (MM).Methods The population that studied consisted of 27 patients with multiple myeloma and 30 healthy controls.The RDW was calculated according to the results of blood routine examination and compared between patients and healthy controls.Then,compared the difference between the two groups of RDW.MM patients were treated with international standard staging (ISS),and the differences of RDW in different stages were analyzed.ISS staging was used to draw the receiver operating curve (receiver operating characteristic curve,ROC curve),then take RDW14.65 ％ as the best cut-off point,the MM patients were divided into low RDW group (RDW=14.65 ％) and high RDW group (RDW ＞14.65％).Overall survival (OS) condition were compared between the above two groups.The impacts of RDW on OS were analyzed by Kaplan-Meier and Log-rank test.Results The average RDW value in experimental and controlled were 15.60 ％ ± 2.35 ％ vs 12.72 ％ ±0.61 ％ separately (t=6.201,P＜0.001),with statistical differences.The average RDW value in low ISS(Ⅰ + Ⅱ stage) and high ISS (Ⅲ stage) were 13.99 ％ ± 1.08％ vs 16.55 ％±2.39％ separately (t=3.800,P=0.001).The median survival time of low RDW and high RDW group was 13 months and 8 months respectively,and the difference was statistically significant (x2=6.481,P =0.011).Conclusion RDW increased in patients with MM,the risk stratification higher prognosis is worse.

Background and objective hTe aim of this study is to establish a HRM (high resolution melting curve) method for detection of deletion in human BIM gene and to detect this site deletion with the above method in 30 lung cancer samples and 30 normal samples. Methods The primers for detection of BIM deletion were designed and synthesized. The HRM method for geng deletion was established. And select the part of samples to detect BIM delection by normal PCR and sequencing assay. hTe Tm value of wild type PCR products was higher than that of the deletion PCR products. hTe difference of the corresponding Tm value is 2.5 oC. Results By detection with HRM methods, 1 samples were conifrmed to be mutant, 7 samples were conifrmed to be heterozygous and the other 22 samples were all wild type in the lung cancer samples. 2 samples were conifrmed to be heterozygous and the other 28 samples were all wild type in the normal samples. Conclusion hTe HRM method for detection of BIM deletion established in this study is a sensitive, accurate, simple and high throughput method.
