目的 调查临床护士对新型冠状病毒肺炎的知信行现状,为制定相关培训策略提供依据。方法 采用便利抽样法,2020年3月选取我院的1 007名临床护士作为研究对象,采用一般资料及临床护士对新型冠状病毒肺炎知信行问卷对其进行调查。结果 1 007名临床护士对新型冠状病毒肺炎的知识、态度、行为得分分别为(28.82±9.22)分、(52.04±5.52)分、(55.38±7.93)分,新型冠状病毒肺炎知信行总分为(136.24±14.52)分。不同年龄、职称、职务、工作年限、何时参加过穿脱防护服操作培训及考核新型冠状病毒肺炎知识得分比较,差异均有统计学意义(P<0.05);工作年限、何时参加过穿脱防护服操作培训及考核,其新型冠状病毒肺炎态度得分比较,差异均有统计学意义(P<0.05);是否参加过穿脱防护服操作的培训及考核、何时参加过穿脱防护服操作培训及考核、是否参加过咽拭子采集的培训及考核的新型冠状病毒肺炎行为得分比较,差异均有统计学意义(P<0.05)。结论 临床护士对新型冠状病毒肺炎的知识得分处于较低水平,态度和行为得分较好,建议护理管理者需加强临床护士对新型冠状病毒肺炎的知识学习及相关培训,以提高护士知识及技能水平。

Objective To investigate the current status of nurses' knowledge, attitude and behavior to new coronavirus pneumonia, to provide the basis for formulating relevant training strategies. Methods In March 2020, 1 007 clinical nurses in our hospital were selected as the research object. The general information and questionnaire about the new coronavirus pneumonia were investigated in these nurses. Results Scores of 1 007 nurses answered the knowledge, attitude and behavior to new coronavirus pneumonia were(28.82±9.22),(52.04±5.52), and(55.38±7.93), respectively. The total score of knowledge, attitude, and behavior to the new coronavirus pneumonia was(136.24±14.52). The differences of scores of knowledge about new coronavirus pneumonia between different ages, job titles, duties, working years, and when they participated in the training and evaluation of wearing and taking off protective clothing were statistically significant (P<0.05). There was a statistically significant difference in the attitude scores of the new coronavirus pneumonia between different working years and when they participated in training and evaluation of wearing protective clothing (P<0.05). There were statistically significant differences in the behavior scores to new coronavirus pneumonia between whether and when they have participated in the training and evaluation of wearing and taking off protective clothing, and whether they had participated in the training and evaluation of pharyngeal swab collection (P<0.05). Conclusion Nurses' knowledge scores for new coronavirus pneumonia are at a low level, but their attitude and behavior scores are higher. It is recommended that new coronavirus pneumonia knowledge and related training should be strengthened for nurses to improve nurses' knowledge and skills.

Objective To express VP3 capsid protein of enterovirus 71 by using Escherichia coli prokaryotic expression system. Methods VP3 gene was amplified by PCR before inserted into pET28a(+) plasmid. Then the plasmid pET28a-VP3 was transformed and expressed in the Escherichia coli BL21 strain at 25 ℃ or 37 ℃. Finally the protein was analyzed by SDS-PAGE gel electrophoresis. Results The pET28a-VP3 plasmid was successfully constructed, and the EV71 VP3 protein was expressed. Supernatant of the production after ultrasonication and centrifugation got a little VP3 protein. Conclusion The EV71 VP3 protein was expressed. Expression at 25 ℃ may lead to the dissolution of the recombinant protein.

目的 分析妊娠期慢性乙型肝炎病毒携带者病毒载量与孕妇肝功能、妊娠并发症的相关性。方法 将本院2015年1月—12月间在本院住院并于本院分娩的携带慢性乙型肝炎病毒(HBV)的86例孕妇作为本次研究对象,于住院期间分娩前测定孕妇HBV脱氧核糖核酸(HBV-DNA)定量,依据HBV-DNA定量测定结果将全部患者分为阴性组与阳性组,分别对比2组患者的临床资料、肝功能、妊娠并发症发生率及母婴结局;分析HBV-DNA载量与孕妇妊娠期肝功能及妊娠并发症的相关性。结果 2组孕妇的年龄、BMI、孕次与产次均无差异,P>0.05;阴性组患者妊娠期肝功能指标优于阳性组,P<0.01。阴性组中羊水量异常(偏多或偏少)发生率高于阳性组,P<0.05;其他妊娠期并发症发生率2组均未见差异,P>0.05。2组母婴结局均未见统计学差异,P>0.05。HBV载量与ALT肝功能指标均呈正相关,0<r<1,说明HBV-DNA越高则ALT越高,孕妇的肝功能越差。HBV载量与并发症发生间基本不相关,|r|<0.3,P>0.05。结论 慢性乙型肝炎病毒携带者妊娠期时随着病毒载量的升高,孕妇的肝功能有所下降仍可维持在正常标准,但与妊娠并发症的发生无相关性;提示对HBV-DNA阳性的孕妇给予密切监护,通过临床常规对症治疗能够保证母婴安全。

Objective To analyze the correlation between viral load of chronic hepatitis B virus infection and liver function and pregnancy complications. Methods We selected 86 cases of pregnant women with chronic hepatitis B virus(HBV)in our hospital from January 2015 to December 2015 as the research objects, and then during the hospitalization to test the quality of the HBV deoxyribonucleic acid (HBV-DNA)for them before delivery. According to the HBV-DNA quantitative results, all patients were divided into low dosage group and high dosage group, and then the clinical data, liver function, the incidence rate of pregnancy complications and the outcomes of the two groups were compared; at last we analyzed the correlation among the HBV-DNA load, liver function of pregnant women during pregnancy and pregnancy complications. Results There was no difference between the two groups of pregnant women in the age, BMI, pregnancy and birth time, P>0.05; the low dose group was better than the high dose group in the liver function index during the pregnancy, P<0.01. The incidence of abnormal amniotic fluid volume (more or less) in the low dose group was higher than that in the high dose group, P<0.05; there was no significant difference between the two groups in the incidence of other complications, P>0.05. There was no statistical difference between the two groups in maternal and neonatal outcomes, P>0.05. The HBV load was positively correlated with the two liver function indexes ALT, 0<r<1, indicating that the higher the HBV-DNA, the higher theALT, the worse the liver function of the pregnant women. There was no correlation between HBV load and complications, |r|<0.3, P>0.05. Conclusion Chronic hepatitis B virus carriers during pregnancy with increasing viral load, liver function of pregnant women declined to maintain in normal level, but not associated with pregnancy complications; that of HBV-DNA positive pregnant women given close monitoring of disease through clinical routine treatment can ensure the safety of mother and child.

Objective To investigate the epidemiological characteristics of herpes simplex virus infection in patients attending a sexually transmitted diseases(STD)clinic in Nanhai District of Foshan. Methods The 350 patients attending the three standardized STD clinic in Nanhai District of Foshan from January,2013 to June,2014 were interviewed with an anonymous questionnaire,blood-tested for HSV(IgM、IgG) antibody.And secretion was detected by FQ-PCR for HSV antigen. Results In 350 patients with suspected GH,the positive rate of HSV-I IgM and IgG were 5.4%(19/350)and 87.7%(307/350).The positive rate of HSV-II IgM and IgG were 2.9%(10/350)and 42%(147/350),respectively.HSV-I infection was principal in two serologic types,and the positive rate of IgG was higher than that of IgM (P<0.05).There were 147 patients infected HSV-II IgG(male 115,female 32).The infection rate is 41.2% and 42.7%.The infection rate of HSV-ⅡDNA in men was higher than that in women.There was a significant difference between them(P<0.05). Conclusion There was a high positive detection rate of HSV from sexually transmitted disease clinic in this region.And HSV-1 was principal.For patients with suspected genital herpes,detection of HSV antigen tests combined with HSV-I、HSV-II IgM and IgG serum antibody tests is more helpful in the clinical diagnosis of genital herpe.HSV infected men patients were likely to clinically diagnose.

       戊型肝炎病毒（HEV）是导致急性肝炎的重要病原体，部分HEV感染者可进展为肝衰竭，此外，慢性感染和肝外表现可也在HEV感染者中发生。全球每年感染HEV的患者数达2000万，其中330万例患者有肝炎相关的临床症状，年死亡例数约为4.4万（2015年数据）。在我国，HEV以散发流行为主。近年来由于对其研究的重视，HEV病原学、流行病学、临床诊疗和预防取得较大的进展，文章拟对目前HEV防治热点以及新进展进行总结和分析。
