OBJECTIVE:To study the risk factors of nosocomial infection(NI)in surgery of a hospital.METHODS:By a retrospective study,a total of 835 surgical medical records in 2007 of a hospital were analyzed statistically.RESULTS:Of the 835 cases reviewed,95 had NI which was related to 13 factors(P

Objective To investigate the risk factors for heart failure in pregnant women with heart disease. Methods A retrospective analysis was made from 340 cases of pregnant women with heart disease in our hospital from January 2008 to December 2013. The pregnant women who presented heart failure were categorized in the observation group (n=65), and others were in the control group (n=275). Data was used to analyze by univariate and multivariate logistic regression for heart failure in pregnant women with heart disease. Results The total 340 cases of heart disease included 132(38.8%) of congenital heart disease, 86(25.3%) of rheumatic heart disease, 63(18.5%) of arrhythmia, 33(9.7%) of hypertensive heart disease and 26(7.6%) of peripartum cardiomyopathy. 65 cases (65/340, 19.1%) presented with heart failure, there were 4 cases resulted in death (1.2%). Multivariate logistic regression analysis showed that age≥35, the baseline parameters of New York Heart Academy (NYHA)≥Ⅱ, pulmonary artery pressure>50 mmHg (1 mmHg=0.133 kPa), baseline heart rate>100 bpm, cardiac events occurred before pregnancy were the independent risk factors for heart failure. Prenatal counseling and antenatal examination were the protective factors for heart failure. Conclusions There are a variety of influencing factors for the heart failure in pregnant women with heart disease. It is necessary to take targeted intervention measures in response to the influencing factors so as to reduce the development of heart failure.

Evidence-based medicine(EBM) is a new medical model,which is an inevitable tendency of modern clinical education.This article analyses the advantages and disadvantages of the evidence-based medical education(EBME) and emphasizes the great significance of EBM in paediatrics teaching.

Shoulder-hand syndrome is a common complication in patients with stroke.This paper would review the therapies or approaches for the shoulder-hand syndrome.

Objective To analyze the clinicopathologic features of primary cutaneous CD30 positive lymphoproliferative disorders. Methods A clinical, pathological and immunohistochemical analysis was carried out in 4 cases of lymphomatoid papulosis and 5 cases of primary cutaneous anaplastic large cell lymphoma. Results Lymphomatoid papulosis was divided into 3 subtypes, A, B and C. The lymphomatoid papulosis of subtype A was pathologically characterized by pleomorphic anaplastic large cells or Steinberg-reed cells scattered or patchly distributed among many inflammatory cells; subtype B showed pathological changes characteristic of granuloma fungoides, and manifested as a broad infiltration zone of lymphocytes in dermis with scattered small- to middle-sized atypical gyrus-like lymphocytes; subtype C was characterized by a diffuse distribution of anaplastic large cells and could clinically subside spontaneously. Primary cutaneous anaplastic large cell lymphoma clinically manifested as subcutaneous nodules or papules, and was pathologically characterized by large, pleomorphic, round or ellipse cells with plentiful, eosinophilic or bicolor cytoplasm, large nuclei and obvious nucleoli. The neoplastic cells characteristically expressed CD30 antigen in both lymphomatoid papulosis and primary cutaneous anaplastic large cell lymphoma, and all the cases showed a favorable prognosis.Conclusions Primary cutaneous CD30 positive lymphoproliferative disorders are a spectrum of cutaneous T cell lymphoma with favorable prognosis, and a synthetic analysis of clinical, histopathological and immunohistochemical findings is beneficial to the diagnosis of these entities.

s Objective To study the effect of HBV DNA of pregnant mothers on HBV intrauterine transmission. Methods Thirty one pairs of mothers and their newborn babies were detected for HBV by the HBV DNA qualitative PCR and HBV serology, as well as the concentration of HBV DNA in the blood by fluorescence quantitative PCR. Results There was a positive linear regression( r=0.5401, P=0.0017 ) between the concentration of HBV DNA in the infant and that in the mothers. Among the 31 infants, 19 showed abnormal by HBV DNA qualitative PCR and(or) HBV serology. It indicated that there was vertical transmission from the mothers to their infants. The transmission rate is 61%. The concentration of HBV DNA copies/ml(7.2?3.1) in mothers whose infants were abnormal was significantly higher than the others(5.8?1.3). Among the 31 mothers, 6 cases showed anti-HB positive and their babies were of much lower concentration of HBV DNA(4.2?1.8) than others(6.1?1.8). Conclusion The quantity of HBV in mothers reflected the strength of HBV vertical transmission and the chance of HBV transmission from mothers to infants have been decreased after mothers have obtained HbsAb.

To examine the protective action and therapeutic effect of anisodamine on acute lung injure and its molecular mechanism,63 rats were randomly divided into three groups :normal control group(NS),lipopolysaccharide (LPS) group and anisodamine (ADM) group.Rat model of acute lung injure(ALI) was produced by injecting LPS(5mg/kg) into the tail vein.The lung index(LI),WBC count,the percentage of polymorphonuclear leukocyte(PMN) in the bronchoalveolar lavage fluid(BALF) were observed at 0,1,3,5 hours(T 0,T 1,T 2,T 3).The concentration of TNF-? were measured both in BALF and plasma at four time points.The expression of P65 was analyzed by immunohistochmical method five hours after injecting LPS.The results showed that LI of ADM group were significantly lower than that of LPS group at T 2 after injecting LPS(P

s:To resolve the problem of the accuracy and standardization of STR PCR typing in forensic science practice,we have designed a new method to produce standard D12S375 allelic ladder.Seven different PCR amplified D12S375 allelic fragments were isolated from the gel,eluted into the distilled water and reamplified by PCR.The purified allelic fragments were then blunt end subcloned individually into the pUC plasmid vectors and transfected into competent E.coli DH5? TM cells.The sequencing results confirmed that the size and the constructure of the inserts were correct.The recombinant plasmids DNA with 7 inserts were then used as templates for reamplification to generate D12S375 standard ladder, with which the genetic polymorphisms of D12S375 locus in Chinese Han population in Chengdu,Hui population in Gansu and Wei population in Xinjiang were studied.
