Objective To know the awareness level of patient-controlled epidual analgesia in labor related knowledge,and to provide evidence for health education,develop a comprehensive intervention program to reduce the rate of cesarean section.Methods Investigation on knowledge of patient controlled epidural analgesia during labor for a total of 400 pregnant women on Maternal and Child Health Hospital of Taiyuan City,MCH Hospital of Shanxi Province by questionnaire.Compared different characteristics of the pregnant women's scores about control epidural analgesia childbirth knowledge by nonparametric test,knowledge score of multi-factor analysis by multiple linear regression analysis.Results The maximum score of pregnant women-controlled epidural analgesia delivery knowledge was 13,the minimum score was 0,the median score was 4,range interquartile was 5.Different pregnant women with different age,education level,number of weeks of gestation,pregnancy,family income,and condition of parnatal care had different scores of knowledge of patient-controlled epidural analgesia,the difference was significant,P＜0.05.Multiple linear regression analysis showed that:pregnant women's education,gestational age,the average monthly household income can be explained by maternal knowledge score of 61.4％ of the variation.Conclusions The level of pregnant women-controlled epidural analgesia childbirth knowledge is low,we need to strengthen the natural childbirth education,and take a variety of modes of propaganda and increase their level of knowledge,enhance confidence of natural childbirth in pregnant women,so as to achieve the purpose of reducing cesarean section rate.

Objective To study the repeat pregnant women′s awareness level of delivery mode knowledge after cesarean section, in order to provide a basis for making effective intervention programs and reduce the cesarean delivery on maternal request rate. Methods Investigated on the knowledge of delivery mode after cesarean section for 330 repeat pregnant women on Maternal and Children Healthy Hospital of Shanxi Province by questionnaire. Results This study investigated 330 repeat pregnant women, recycling effective questionnaire 318, and the recycling effective rate was 96.4%. Different pregnant women with different education level, the number of weeks of gestation, the doctors′recommendations on the delivery had different scores of knowledge of delivery mode after cesarean section. The difference was significant (P < 0.05). The Multi-factor Logistics regression analysis showed that the repeat pregnant women′ s education and the doctors′recommendations on the delivery are associated with the scores of knowledge of delivery mode after cesarean section (P<0.05). The more higher level of their education, and if the doctor had provided the advice of delivery mode to repeat pregnant women before, the more higher scores the repeat pregnant women got. Conclusions The level of the knowledge of delivery mode after cesarean section is low. It′s time to take appropriate health education intervention strategies to reduce the rate of cesarean delivery on maternal request.

Objective To observe the relation between the changes of plasma TpP and D-dimer in patients with acute cerebral infarction( ACI).Methods D-dimer and thrombus precursor protein (TpP) levels in plasma of 55 cases with ACI during early phase and 25 normal healthy subjects were detected,and 24/55 cases were measured dynamically. D-dimer levels were detected by automated latex D-dimer immunoassay. Plasma TpP level was determined using a new assay,the TpP_ TM(USA),which is based on an ELISA method.Results There was significant difference(P

A monoclonal antibody 1C34-5 raised against human peripheral mononuclear cells was produced. This antibody, a monoclonal IgG1. showed positive reaction with about 90% of T and B lymphocytes, monocytes. granulocytes and bone marrow cells, but negative reaction with red blood cells and platelets by indirect immunoflurorescent technique. 1C34-5 also reacted with leucocytic cell lines except a non-T non-B lymphoid line Reh but not with erythroid line K562, HeLa cells and fibroblast cells so far tested.This antibody was also assayed histologically by an indirect immunoperoxidase technique against a variety of human normal tissue frozen sections. It was found that 1C34-5 bound to all lymphoid tissues including lymph nodes, tonsil, thymus. Peyer's patches and leucocytes scattered in other tissues, but not to all non-hematopoietic tissues as well as erythropoietic foci in fetal liver. Thus. 1C34-5 appears to recognize a human leucocyte antigen specifically.

Objectives To explore the efficacy of CaNa2EDTA in the treatment of chronic moderate lead poisoning, so as to optimize the chelation therapy for lead poisoning in children. Methods The clinical data of 14 patients with chronic moderate lead poisoning treated with CaNa2EDTA for 3 consecutive courses of lead removal during September 2014 to December 2016 were analyzed retrospectively. Twenty-four hour urinary lead levels during hospitalization were analyzed. The changes of blood lead levels before treatment, 3 days, and 5 days after treatment were also analyzed. Results In the 14 children (4 males and 10 females) average age was 2.35±1.47 years. After treatment with CaNa2EDTA for 3 consecutive courses, the blood lead levels were decreased significantly in all the patients, and the blood lead levels at 3 days after treatment were 0.76, 0.77, 0.72 times those at 5 days after treatment respectively. The decrease of blood lead levels per unit of drug in the first 3 days of treatment were significantly higher than those in 5 days of treatment (P<0.05). The decrease of blood lead levels at 3 days after treatment was 0.65, 0.71, 0.70 times , those in 5 days' treatment respectively. The decrease of urine lead levels per unit of drug in the first 3 days of treatment were significantly higher than those in 5 days of treatment (P<0.05). Conclusions CaNa2EDTA has an obvious effect on removal of lead.The efficiency of lead removal in 3 days of treatment was higher than in 5 days of treatment. Thus, a course of treatment for 3 days may be an altenative for a course of 5 days.

Objective To determine Neisseria gonorrhoeae multi-antigen sequence typing (NG-MAST) sequence types in different geographical areas of China,including Changzhou and Yangzhou cities of Jiangsu province,Wuzhou and Hezhou cities in Guangxi Zhuang Autonomous region,Sanya and Qionghai cities of Hainan province,Jiangmen and Maoming cities of Guangdong province.Methods DNA was extracted using Qiagen DX extraction kits from 88 urine samples which were collected from male patients attending sexually transmitted disease (STD) clinics and positive for nucleic acid amplification test (NAAT) for N.gonorrhoeae.Two rounds of PCR were carried out to amplify the porB and tbpB genes of N.gonorrhoeae followed by gene sequencing.Sequence alignment was performed on the NG-MAST website (http://www.ng-mast.net) to determine the genotype of N.gonorrhoeae.Results The first-round PCR yielded positive results for porB and tbpB in 13.6％ (12/88) and 14.8％ (13/88),respectively,of these urine specimens,and 12 samples were successfully genotyped with the efficiency of genotyping being 13.6％.The amplification efficiency of second-round PCR was enhanced to 71.6％ and 72.7％ for porB and tbpB,respectively,and the efficiency of genotyping increased to 70.5％ (62/88).Compared with the first-round PCR,the second-round PCR showed an increase in amplification efficiency for porB and tbpB by 58.0％ and 57.9％ respectively,as well as in genotyping efficiency by 56.9％.Forty-five genotypes were identified in the 62 samples,including 40 known genotypes and 5 novel genotypes.Of these genotypes,ST1866 was the most abundant (6/62),followed by ST1972 (4/62) and ST3356 (4/62),all of which were from Jiangsu province.The ST532 genotype was identified in 3 samples from Guangdong province,ST2221 genotype in 2 samples from Guangxi Zhuang Autonomous region.Each of the remaining genotypes was identified in only 1 sample and scattered in all of these cities.The 5 novel MAST-genotypes were as follows:porB-892 and tbpB-46 (98％ similarity),porB-130 and tbpB-504 (96％ similarity),porB-2790 and tbpB-32 (99％ similarity),porB-1053 and tbpB-856 (99％ similarity).Conclusions Urine samples can be used for NG-MAST analysis,and two rounds of PCR can enhance the efficiency of genotyping.NG-MAST genotypes appear to be diverse in different geographical areas of China.

Objective To assess the prevalence of urogenital infection with and genotype distribution of C.trachomatis among female sex workers (FSWs) from different entertainment venues in Wuzhou and Hezhou cities of Guangxi Zhuang Autonomous Region.Methods A total of 810 FSWs were recruited to this study by convenience sampling from entertainment venues in Wuzhou and Hezhou cities of Guangxi Zhuang Autonomous Region from July 2009 to September 2010.Based on the venues where they solicited clients,the FSWs were classified into three tiers,i.e.,high-tier,middle-tier and low-tier.Cervical swabs were collected from all of these subjects followed by detection of C.trachomatis with the Amplicor PCR test kit.Then,DNA was extracted from C.trachomatis-positive specimens and subjected to nested PCR assay targeting the ompA gene followed by bidirectional sequencing.The genotype of C.trachomatis was determined according to the sequence of ompA gene.Chi-square test was conducted to compare the urogenital infection rate and genotype distribution of C.trachomatis between different tiers of FSWs.Results Among the 805 FSWs,the prevalence rate of urogenital C.trachomatis infection was 20.0％ (161/805).Chi-square test showed that the prevalence rate of urogenital C.trachomatis infection was significantly lower in high-and middle-tier FSWs than in low-tier FSWs (x2 =3.97,5.95,respectively,both P ＜ 0.05).Nine genotypes of C.trachomatis were identified in these FSWs,with serotype F as the most prevalent genotype (39/154,25.3％).Low-tier FSWs showed a higher frequency of genotype E (x2 =5.02,P ＜ 0.05) but a lower frequency of genotype K (Fisher's Exact test,P =0.048) compared with middle-tier FSWs.Conclusions Low-tier FSWs show a high rate of urogenital infection with C.trachomatis,with serotype E as the prevalent type.Since C.trachomatis serovar E-infected patients are likely to be missed by symptom-based screening and preventive strategies,standardized screening for and efficient treatment of urogenital C.trachomatis infection should be enhanced among low-tier FSWs for the prevention of C.trachomatis transmission.
