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.

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.

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.
