This article analyzes the risk factors of cystospasm and the related nursing countermeasure during cystospasm. The risk factors of cystospasm were analyzed by checking literature published in recent years. These studies suggest that only by fully understanding the risk factors of cystospasm can we take corresponding nursing measures on the patients. At the same time the occurrence of cystospasm can be reduced. It also can relieve the patients' pain and anxiety and help the patients recover earlier.

Multi-drug resistance(MDR) is the most frequent reason for tumor chemotherapeutic failure.ATP binding cassette(ABC) drug transporters play an important role in tumor MDR.ABCC1 is one of the members of ABC transporter super-family,which lead to drug risistance via discarding drug out of cell or changing the drug distribution in a cell.In this article,we reviewed the advance in MDR mediated by ABCC1 and its reverse.

Objective:To investigate the use of antibacterial drugs during the perioperative period of a cesarean section and observe the differences before and after antibacterial drug remediation. Methods:1 569 cesarean cases from 2010 to 2012 were investigated, and the use of antibacterial drugs, drug categories, drug combinations, medical expenses, and so on was statistically analyzed with the use of the statistical software SPSS13. 0. Results:The rate of antibacterial drug usage within the 1 569 cesarean cases was 100%;for pre-operative antibacterial drug remediation, azithromycin, cefathiamidine, and ornidazole were the top three, while the top three antibacterial drugs for post-oper-ative remediation were arecefathiamidine, cefuroxime, and clindamycin. There was no significant difference between the two groups of incision infections, and the rate for combined use of drugs dropped. The analysis of drug costs is of statistical significance. Conclusion:The analysis of antibacterial drug remediation is useful for the rational use of anti-bacterial drugs and a reduction of costs.

Objective To observe the incidence of vaccinating BCG vaccine according to plan in bronchiolitis developed into child bronchial asthma in the future.Methods Using the method of retrospective study and clinical follow-up,chosen 280 children diagnosed with bronchiolitis from January 1995 to December 2002,135 cases were vaccinated BCG vaccine according to plan (vaccinated BCG group),145 cases were not vaccinated BCG vaccine according to plan (non-vaccinated BCG group),followed up for 3-10 years,the incidence of bronchial asthma between two groups were compared.Results The incidence of bronchial asthma in vaccinated BCG group was lower than that in non-vaccinated BCG group [17.04％(23/135) vs.40.69％(59/145)],there was significant difference (P＜ 0.01).Conclusions It's easy for bronchiolitis developing into bronchial asthma in children.Vaccinating BCG vaccine in time in occurrence of bronchial asthma show a protective effect in the future.

Objective To investigate the role of MDM2in the cell proliferation and carcinogenesis in condyloma acuminatum(CA).Methods The technique of immunohistochemistry and in situ hybridization were used to detect the expression of MDM2protein and mRNA in skin lesions of CA and normal skin of genital area.Polymerase-chain reaction(PCR)was used to type HPV DNA.Results Out of32CA specimens,the expression of MDM2protein was found in18(56.25%),the expression of MDM2mRNA was found in22(68.75%),while co-expression of MDM2protein and MDM2mRNA was found in14.According to PCR results,HPV6/11subtype was shown in28out of32CA specimens(87.5%),and HPV16/18subtype was shown in4out of32(12.5%).In eighteen out of positive specimens expressing MDM2protein,HPV6/11subtype was shown in15and HPV16/18subtype3.In twenty-two positive specimens expressing MDM2mRNA,there were HPV6/11subtype in18,and4were HPV16/18subtype.No expression of MDM2protein and MDM2mRNA was observed in normal skin.Conclusion The overexpression of MDM2may be involved in malignant proliferation and carcinomatous change of condyloma acuminatum.

Objective To research the impact of various PEEP parameters of mechanical ventilation on liver mor-phology and function and on hemodynamics. Methods Fifty patients of respiratory failure due to COPD using mechanical ventilation was observed by prospective, exoterical and self-control methods after their condition were stabilized. The varia-tion of abdominal pressure was measured with different PEEP of 0 cmH2O, 5 cmH2O and 10 cmH2O with mechanical ventila-tion, and measured when patients breathe autonomously with tracheostomy tube. The changes of liver morphology, hepatic por-tal vein diameter, hemodynamics and liver function were also measured on above circumstances. Results With PEEP value increases:the abdominal pressure (IAP) rise (P＜0.01) while liver morphology, function and hepatic portal did not change markedly evidently (P>0.05). By contrast, blood flow of hepatic portal vein reduced with PEEP increase (P＜0.05). Conclu-sion Higher PEEP values on mechanical ventilation will causes abdominal pressure increases and low blood flow of hepatic portal , but not obvious impact on portal vein diameter and liver function.

Objective To get a knowledge of the current status of international research on Ebola virus and Ebola virus disease (EVD).Methods All the articles about EVD from PubMed database were retrieved and analyzed.After core subject headings had been identified by BICOMB,the co-occurrence matrix was established.Cluster analysis about co-occurrence matrix was performed by SPSS 19.0.The visualized network image was drawn by Ucinet 6.0.Results A total of 1 384 literatures were involved in the analysis,with the earliest one published in 1979.The number of literatures was increasing along with time and disease outbreaks.Totally 1 213 (87.6％) literatures were published by Europe and U.S.There were 27 core subjects and they were clustered into 3 research areas from 1979 to 2014,including Ebola virus genome structure and viral proteins,especially the envelope protein; immunology of Ebola virus and animal models; epidemiology,diagnosis and treatment of Ebola hemorrhagic fever.The visualized social network reflected that the prevention of EVD,the genome and immunology of Ebola were the major concerns.Conclusion It has been 35 years since the literatures on Ebola virus and EVD emerged.The United States and the United Kingdom are the top two countries in this field.The present studies have laid a crucial foundations for developing effective vaccines and diagnostic reagents.

Chronic obstructive pulmonary disease (COPD) is a chronic airway diseases,which leads to heavy social and economic burden to our country.We can use serum biomarkers to evaluate diagnosis,classification,treatment and prognosis of COPD.The change of biomarkers provides lots of valuable clinical information.A variety of biomarkers are associated with the severity of lung function,which can be used to judge disease severity.Some indicators are related to the diagnosis of acute exacerbation or hospitalization risk.Some serum markers would guide therapy and can be effectively applied to clinical work.Study of COPD serum biomarkers would provide more reference information for clinical physicians in diagnosis,treatment and prognosis of COPD.

Objective To learn about the antibiotic resistance status of methicillin resistant coagulase negative staphylococcus(MRCNS),and to investigate the distribution and resistant feature of different staphylococcal chromosomal cassette mec(SCCmec) genotypes of children in Anhui,so as to guide clinical medication.Methods Resistance phenotype screening was conducted in coagulase negative staphylococcus,which were isolated from clinical strains in children in Anhui from 2010 to 2014 each year in September.MecA gene was detected by using PCR method in order to collect MRCNS.Minimal inhibitory concentrations (MIC) of 16 antibiotics were determined by adopting agar dilution method.Vacomycin-resistant strains were identified with population analysis and the Brain Heart Infusion vancomycin screen agar dilution method recommended by Clinical and Laboratory Standards Institute in 2013.Van gene and SCCmec types were detected by using PCR method.Results A total of 148 MRCNS strains were detected through the resistance phenotype screening and the detection of mecA gene.There were methicillin resistant staphylococcus epidermidis,methicillin resistant staphylococcus haemolyticus,methicillin resistant staphylococcus hominis,and other kinds of MRCNS,and the proportions of them were 44.59％ (66/148 cases),25.68％ (38/148 cases),19.59％ (29/148 cases) and 10.14％ (15/148 cases),respectively.The analysis of antibiotic resistance showed the antimicrobial resistant rates of MRCNS to Penicillin,Cefoperazone,Cefotaxime,Ceftriaxone,lmipenem and Meropenem were all 100％,to Erythromycin and Azithromycin,Ciprofloxacin,Clindamycin,Gentamicin,Lewofloxacin,Rifampincin,Chloramphenicol,Teicoplanin and Vancomycin were 92.57％,97.98％,83.78％,79.05％,43.24％,35.81％,24.32％,8.78％,2.03％ and 0.68％,respectively.There was 1 heterogeneous Vancomycin-resistant strain,which was resistant to both Vancomycin and Teicoplanin (with MIC 32.00 mg/L and 64.00 mg/L).No vanA,vanB,vanC1 or vanC2/3 gene was detected from heterogeneous Vancomycin-resistant strain by PCR.Ⅰ to Ⅴ SCCmec genotypes were detected from 148 MRCNS strains,and the major SCCmec type was SCCmec type Ⅲ,which was followed by hybrid type.Three subtypes of SCCmec type Ⅳ were identified,including Ⅳa,Ⅳc and Ⅳd.There were 148 MRCNS strains that showed different resistant phenotypes to various antibiotics.Conclusions The MRCNS strains of children in Anhui province showed multiple resistance to antibiotics.It should be on alert when heterogeneous Vaneomycin-resistant strain appeared.There were several different SCCmec types among several kinds of MRCNS,and SCCmec Ⅲ genotype was the major epidemic isolate.There was no significant correlation between the different resistance rates of non-β-lactamase antibiotics and SCCmec genotypes in MRCNS.
