Objective To discriminate the species and individual identification with mitochondrial DNA (mtD-NA) sequencing in forensic medicine practice. Methods The multiplex PCR of mtDNA loop - D high - variation region and cytochrome- b region were investigated. The PCR products were detected with silver- stain method,followed by analysis of the PCR products with fluorescence sequence technique. Results The presence of two bands (358bp,279bp ) indicated the samples were from human, while only one band of 358bp indicated nonhuman origin. The part of mitochondrial DNA loop - D high - variation region (15997 ~ 16236) from 131 unrelated individuals of Guangdong population were sequenced. In all of these samples there were 69 nucleotide variations and 67 haplo-types.There was 2.679 mutation sites on average per person. The polymorphism was 97.92% . Conclusion The methods described here are reliable and very useful in species and personal identification of degraded samples.

ObjectiveTo investigate the related factors of the occurrence of nosocomial infection and nursing management in operating room for general surgery patients,and provide a scientific basis to reduce the incidence of nosocomial infection of the operating room. Methods304 patients with nosocomial infection from August 2009 to August 2010 in our hospital for surgery were set as the control group.151 cases from September 2010 to October 2011 were named as the intervention group.All cases were analyzed retrospectively.The nursing factors which might affect nosocomial infection in operation room were analyzed by univariate and multivariate logistic regression analysis. ResultsBy univariate analysis,eight operation room nursing factors related to nosocomial infection were screened out:the type of incision,operation time,the following surgery or not,into ICU time,preoperative use of antibiotics,visitors of operations or not,invasive operation.5 highly correlated factors were screened out by multi-factor logistic regression analysis:admission to the ICU time,incision type,operation time,preoperative use of antibiotics,then following surgery.The infection rate and prolapse rate of the control group were significantly higher than those of the intervention group. ConclusionsIn nursing work of the operation room,we can take a series of nursing management interventions to reduce the incidence of nosocomial infection of general surgery.

Objective To explore the effects of ultraviolet on DNA damage in keratinocytes and to observe the protective role of resveratrol for the cells. Methods Comet assay was employed to evaluate the damage after radiation with different doses of UV rays (UVA, UVB and UVC) of 0, 10, 30, 50, 70 and 90 mJ/cm2, and the effects after pretreatment with various concentrations of resveratrol under irradiation with 30 mJ/cm2. Results UVA irradiation (0 ~ 90 mJ/cm2) had no significant effects on HaCaT cells. However, TailDNA%, TailLength, CometLength, TailMoment and OliveTailMoment showed both UVB and UVC induced DNA damage in a dose-de-pentent manner. UVC was more harmful than UVB at the same dose. Conclusions The DNA breakage induced by UVB and UVC is dose-dependent. As compared with UVB, UVC is more harmful to HaCaT cells. Resveratrol exerts a protective effect in HaCaT cells irradiated by UVB or UVC.

Objective To investigate the organic pollutants in the contaminated water irrigation area soil and to study the lipid peroxidation effect of the pollutants on mouse. Methods The organic pollutants of the polluted irrigation soil and control soil were extracted using the supersonic oscillator. The ingredients of the organic pollutants were measured by the GC-MS spectrum. The 40 sanitary Kunming mice were randomly divided into five groups: the dimethylsulfoxide control group,low dose group of control soil,high dose group of control soil,low dose group of polluted soil,high dose group of polluted soil. The administered doses of the low and high dose groups were 25.5 g dry soil/kg body weight per day by oral for two weeks. The activities of T-SOD,GSH-Px and the content of MDA in serum of mice were determined. Results Phenanthrene,yrene,diphenyl,fluorene,naphthalene,dimethyl-naphthalene,2,3,6-trimethyl-naphthalene,anthracene,dimethyl-anthracene,1,4-dimethyl-anthracene,fluoranthene,4-methyl-pyrene,dibenzothiophen,4-methyl-dibenzofuran,dibenzofuran,butylated-hydroxytoluene,dodecane,neopentyl-cyclohexane,trimethyl-heptane,1,2-dimethyl-cyclohexanimine,butethal were detected in the polluted irrigation soil and their levels were 14.3,2.1,1.3,1.1,0.8,1.3,0.4,2.9,7.2,2.3,9.1,0.2,0.4,1.4,1.7,0.37,0.9,0.11,0.02,0.02 and 0.13 mg/kg respectively in the polluted irrigation soil. Trimethyl-heptane,dimethyl-heptane and 1,2-dimethyl-cyclohexanimine were detected,and their levels were all 0.01 mg/kg in control soil. Compared with the solvent of dimethylsulfoxide group,the activities of T-SOD and GSH-Px of the high dose group of control soil and two dose groups of polluted soil all decreased,the differences were all significant(P0.05). Conclusion The soil has been contaminated with organic pollutants in the investigated area and the soil extract may produce a certain effect on lipid peroxidation in mice.
