Objective To understand the prevalence of Toxoplasma gondii infection and its risk factors among healthy blood donation population in Shijiazhuang City,Hebei Province,so as to provide the evidence for developing effective prevention and control measures. Methods A total of 1630 cases of blood donors in Shijiazhuang City were chosen as respondents,and all the respondents were qualified to the standard of blood donation. The antibodies to T. gondii were detected by using ELISA. The in-fection rates of T. gondii in blood donation population were compared between/among different genders,ages,occupations,edu-cation levels,and places of residence. The risk factors for Toxoplasma infection were surveyed with questionnaires. Results A total of 1630 cases of healthy blood donors were investigated,and among which 126 cases were positive in the detection of anti-bodies to T. gondii and the positive rate was 7.73%. The positive rates between/among the different genders,ages,occupations, and education levels were significantly different( χ2 =4.36,13.98,9.71,7.65,respectively,all P < 0.05),and the positive rates among different places of residence were not significantly different( χ2 =1.63,P>0.05). The questionnaire survey showed that the T. gondii infection was closely related to keeping pets,outside eating frequently,having chafing dish or barbe-cue,sharing cutting board for cooked and uncooked food,and no the habit of washing hands before meals. Conclusions The infection rate of T. gondii is relatively high among the healthy blood donation population in Shijiazhuang region. The cognitive ed-ucation for T. gondii infection and infection monitoring are the keys to avoid the transfusion infection.

Objective To study the superiority and safety of cup-shaped womb manipulator auxiliary peritoneoscope in entire womb excision. Methods 180 cases with hysterectomy were randomly divided into cup-shaped womb manipulator auxiliary peritoneoscope group(treatment group) and tradition into the abdominal group( control group) ,and the amount of bleeding and postoperative complications,and patient recovery were observed in the two groups. Results Compared with the control group, the quality of life of patients with anal exhaust time, average length of staying, postoperative recovery daily time were significantly improved, and there were statistically significant differences between two groups ( P ＜ 0. 05 ). There was no serious complication in the two groups. Conclusion Cup-shaped womb manipulator auxiliary peritoneoscope hysterectomy was a safe and feasible operation,and could relieve harm and improve patients quality of life.

Objective To analyze the relationship between pre － pregnancy body mass index ( BMI) ，gestational weight gain ( GWG) and the birth weight of infants，and explore the effect of weight change before and during pregnancy on low birth weight ( LBW) and macrosomia． Methods Women were enrolled by the Chinese Pregnant Women Cohort Study during first trimester． Each respondent＇s weight before and during pregnancy and the birth weight of infant were collected after fellow up． Prepregnancy BMI was divided into underweight，normal and overweight /obesity groups and GWG was divided into suitable， insufficient and excessive groups． Multivariate Logistic regression was adopted to explore the relationship be- tween pre－pregnancy BMI，GWG and newborn＇s birth weight． Ｒesults Women＇s prepregnancy BMI and GWG were associated with neonatal birth weight ( all P＜0. 05) ． Prepregnancy overweight or obesity ( OＲ=2. 339，95% CI: 1. 674－2. 282，P＜0. 001) and excessive GWG ( OＲ= 1. 398，95% CI: 1. 188－1. 978，P= 0. 048) were shown as risk factors for macrosomia． Insufficient GWG increased LBW risk ( OＲ = 1. 479， 95% CI: 1. 461－1. 679，P= 0. 035) while excessive GWG declined LBW risk ( OＲ= 0. 428，95% CI: 0. 225 －0. 817，P= 0. 010) ． Under weight－insufficient GWG was risk factor of LBW ( OＲ= 1. 335，95% CI: 1. 048 －2. 319，P= 0. 048) while normal BMI－excessive GWG ( OＲ= 1. 088，95% CI: 1. 016－1. 675，P= 0. 038) and overweight /obesity－excessive GWG ( OＲ= 1. 498，95% CI: 1. 244－2. 017，P= 0. 046) were associated with higher risk of delivering macrosomia． Conclusions Prepregnancy BMI and GWG were associated with infant＇s birth weight and women were suggested to maintain their weight in recommended range before and during pregnancy．

Acute myeloid leukemia (AML) is a genetic heterogeneous disease in which primordial and juvenile myeloid cells proliferate or accumulate abnormally in bone marrow, peripheral blood and other tissues, resulting in damage to normal hematopoietic function. Studies have shown that about 30% of AML patients have FMS-like tyrosine kinase 3 (FLT3), FLT3 abnormal regulation is closely related to the occurrence and development of AML. At present, FLT3 has become an important target for developing small molecular targeted drugs. Currently, a variety of FLT3 inhibitors and FLT3 degraders have been developed targeting FLT3, and some compounds have exhibited good anti-AML activity. This article summarizes and sorts out the current mainstream drugs for AML therapeutic targeting FLT3, in order to provide a reference for the development and design of AML drugs.

The selection of the prosthetic material determine the success or failure of hip arthroplasty. Currently, the metals, ceramics, polymer composites and carbon materials are the main prosthetic materials of artificial hip joint. They have some progresses in biocompatibility, elastic modulus,mechanical properties, useful life, but they still can't reach the ideal standard of design. In this essay, we mainly review the characteristics and applications of the current artificial hip joint materials through its classification in order to provide a reference for choosing appropriate hip joint materials in clinic and increasing characteristic of materials. We consider the polymer composites has more advantages such as biocompatibility, mechanical properties, corrosion resistance and price, even if it has shortages in abrasion resistance. As the researches of polymer composites are main focus on abrasion resistance, articular surface and strength,and its performances are increased fast, it has a wide prospect in future.
