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.

Objective To investigate the critical thinking ability of medical students and its related factors in order to provide evidence for higher medical education reform. Methods A total of 325 medical students were selected by cluster sampling method, and Critical Thinking Disposition Inventory-Chinese Version (CTDI-CV) was adopted for survery. Results The average total score of critical thinking ability of medical students was above 280, and 51.08% of students showed positive critical thinking ability. Among all the seven critical thinking dispositions, average scores of each item were all positive (>40) except that the significance of truth seeking (37.23) and systematicity (39.05) were indefinite. There were significant differences in critical thinking ability between medical students with different gender and academic years (P<0.05). Conclusion The critical thinking ability of medical students is positive, however, there still exist some shortages. An equal relationship between teachers and students should be established, the traditional course system be continuously reformed, a good environment for clinical training be created, and a variety of teaching methods be implemented to further strengthen the critical thinking ability of medical students.

Objective To investigate the change of cardiac function in elderly hypertensive patients with heart valve degenerative by echocardiography.Methods A total of 126 cases were divided into a valve disease group and non-valve disease group groups.The parameters of trial size,cardiac function and pulmonary artery pressure were detected.Results Of all 126 cases were the patients with hypertension including 28.6% (36/126) of valve disease group and 71.4% (90/126) of non-valve disease.There were 31 cases with mitral valve disease,22 cases with tricuspid valve disease; 26 cases with aortic valve disease; 36 cases with double or three alvular lesions in valve disease group.There was a significant difference in ventricle size and systolic function among valve disease group and non-valve disease group and control group.But there was no significant difference in thickness of ventricular wall between valve disease group and non-valve disease group.Conclusion The elderly hypertensive patient with valve disease was an independent factor for the development of congestive heart failure.
