Objective To analyze the prevalence of human papilloma virus(HPV) and the relationship between HPV and vaginal environment in puerperium women.Methods One thousand and twenty-nine cases puerperium women were detected for HPV subtype by using nucleic acid flow-through hybridization.Patients with HPV positive had been considered as observe group and the rest as control.The prenatal infection of HPV of HPV-DNA positive and negative postpartum puerperium women, and the vaginal cleanliness of prenatal and postpartum were analyzed.Results In 1 029 cases puerperium women, the total HPV-DNA positive rate was 10.30％(106/1029) ,and high risk infection rate was 95.65％ (110/115).The rate of HPV positive before pregnant in HPV positive group (46.51％, 40/86) was higher than that in HPV negative group (9.09％, 10/110).There was significant difference of vaginal environment in the two groups (x2 =36.567, P＜0.05).In HPV-DNA positive and negative women during the puerperium vaginal cleaning degree of Ⅰ , Ⅱ ratio prenatal respectively were 56.98％ (49/86) and 76.36％ (84/110), and the difference was significant (x2 =8.317, P ＜0.05).Postpartum to 45.35％ (39/86) and 60.00 (66/110), and the difference was significant (x2 =3.941, P＜0.05).Conclusion The HPV infection of pregnant women are easy to getagain.There is relevance between HPV infection and vaginal environment.

Objective To study the effect of clopidogrel on different CYP2C19 genotypes and platelet reactivity in acute cerebral infarction patients with antiplatelet aggregation.Methods Four hundred and seventy-four cases of cerebral infarction patients in Beijing Tiantan Hospital Affiliated to Capital Medical University from April 2015 to April 2016 were collected.CYP2C19 genotype was determined,and the genotype was divided into the wild type group,the heterozygous type group and the mutant homozygous group.Platelet aggregation inhibition rate(ADP%) and platelet reactivity index induced by ADP were detected.Patients were divided into clopidogrel resistance group(group CR) and non resistant group according to whether ADP% was less than 30.SPSS 16.0 statistical software was used for statistical analysis,the comparison between groups using independent samples t test,chi square test and multivariate analysis using Logistic regression analysis,when P<0.05 difference was statistically significant.Results Among the 474 patients,204 cases(43.04%) were divided into wild-type group,and 204(43.04%) and 66(13.92%) were divided into the mutant heterozygous group and mutant homozygous group.In Chi square test analysis,clopidogrel resistance group and non resistance group CYP2C19 genotype distribution was significantly different(χ2=6.658,P=0.036).CR group angle(α) values((68.87±5.47)°) and MA((66.77±6.25) mm) were higher than that of CS group ((66.55±6.05)° and (63.30±5.66) mm,t=2.199,3.387,P=0.029,0.001).The multivariate logistic regression analysis showed that OR of angle level was 1.028,95%CI was 0.929-1.137 (P=0.595);OR of Ma level was 1.561,95%CI was 0.785-0.970 (P=0.012).Conclusion The effect of clopidogrel on platelet aggregation in patients with acute cerebral infarction is decreased by CYP2C19 gene mutation.CYP2C19 mutant allele is a risk factor for clopidogrel resistance.Angle (α) value and MA value are the risk factors for the diagnosis of CR in the patients with acute cerebral infarction,and the risk of clopidogrel resistance increased when the patients′ Angle (α) value and the value of MA increased.MA value as a predictor of CR and the screening tool has a certain value.

The cost accounting plays central role in enhancing financial management in the hospital. With the increasing hospital competition, conventional model of cost accounting is changing, and gradually replaced with a novel model of cost accounting-total cost accounting. With the wide spread of total cost accounting in all hospitals, it is found that the general operation of hospitals is limited by the original HIS information system. EPR system feathered with the advanced data administration and potent function of financial analysis holding promise in adoption and acceptance by hospitals, serving as information collector and analyzer following HIS system.
