Objective To study the change of maternal serum human chorionic gonadotropin(MShCG) in preterm labor and the relationship between hCG and placental pathological changes. Metheds The preterm labor patients were chosen as the research subjects, the normal late-pregnancy women with the same gestational age were chosen as controls. MShCG level were measured by radioimmunoassy (RIA), placental tissue of preterm labor women was examined histologically. hCG in placental tissue was examined by semiquantiative immunohistochemistry. Results MShCG in preterm labor was significantly higher than that of control P

In the modern biotechnology era,the important disease genetic resources become the most dependent factor.We expound the actuality of the collection,storage and use of the important disease genetic resources in China,and discuss the problems and challenges we meet.So the chief mission we should do is establishing the database and collecting,storing and using these valuable resources under standard procedure with aim,plan and organization.

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 explore the effects of amlodipine,perindopril and valsartan on plasma adiponectin and retinol binding protein 4 in elderly patients with essential hypertension.Methods From March 2007 to July 2010,238 elderly patients with essential hypertension were selected and 193 cases completed this study.Patients were randomly divided into 3 groups:amlodipine group (n=68),perindoprilgroup (n=60) and valsartan group (n=65).Patients in each group were treated with amlodipine,perindopril and valsartan respectively for at least 12 weeks.The changes in blood pressure,heart rate,body height,body mass index (BMI),abdominal circumference,waist circumference (WC),levels of blood lipids,plasma adiponection and retinol binding protein 4 were observed before and after treatment.Results Compared with pre-treatment,systolic blood pressure in 3 groups were significantly decreased after treatment (all P＜0.01).There were no significant differences in blood pressure among 3 groups after treatment (all P＞0.05).Compared with pre treatment,plasma adiponectin level was significantly increased in perindopril group and valsartan group after treatment [(7.4±1.8) μg/L vs.(8.3± 1.8) μg/L,(7.5±1.7) μg/L vs.(8.4±1.9)μg/L,both P＜0.01].Plasma adiponectin level was higher in perindopril group and valsartan group than in amlodipine group after treatment [(8.3±1.8) μg/L vs.(7.6±1.8) μg/L,(8.4±1.9) μg/Lvs.(7.6±1.8) μg/L,both P＜0.05].Compared with pretreatment,plasma retinol binding protein 4 level in 3 groups were all decreased after treatment,and the decrements had significant differences in perindopril group and valsartan group (both P＜0.01) but had no difference in amlodipine group (P＞0.05).Plasma adiponectin retinol binding protein 4 levels were lower in perindopril group and valsartan group than in amlodipine group after treatment[(36.6± 14.2) μg/L vs.(42.7± 13.8) μg/L,(36.3±14.1) μg/L vs.(42.7±13.8) μg/L,respectively,both P＜0.01].Conclusions Perindopril and valsartan play important roles in cardiovascular protection beyond the antihypertensive effects by increasing plasma adiponection level and decreasing plasma retinol binding protein 4 level in elderly patients with hypertension.

Objective To retrospectively analyze the relationship of the classification and risk stratification in senile hypertension with benign prostatic byperplasia (BPH).Methods Totally 376 male senior patients,including 233 senile hypertensive patients and 143 non-hypertensive patients as a control,were enrolled in this study.There were 35 cases of hypertension at level 1,82 cases at level 2,116 cases at level 3.Based on risk stratification of hypertension,there were 3 cases of low-risk,28 cases of medium risk,75 cases of high-risk,127 cases of very high risk.All candidates accepted the International Prostatic Symptom Score (IPSS) assessment before the treatment.Fasting blood glucose (FBG),total cholesterol (TC),triglycerides (TG),low density lipoprotein cholesterol (LDL-C),high density lipoprotein cholesterol (HDL-C) and prostate specific antigen (PSA) were determined.Body mass index (BMI) and prostate volume (PV) were calculated.Relationship of classification and risk stratification in hypertension with BPH were analyzed.Results The levels of systolic blood pressurc (SBP),diastolic blood pressure (DBP),body weight,BMI,FBG and TC were higher (t=3.883,2.498,2.161,3.399,2.200,2.370,P＜0.05 or P＜0.01),while serum HDL-C were lower (t=2.036,P＜0.05) in hypertensive patients than in control group.Compared with the control group,IPSS and PV was increased (t =3.432,3.381,both P＜0.01) in hypertension group.Risk rate of hypertensive patients with BPH was 2.03 times (95％CI:1.33-3.11,P＜0.01) as compared with control group.In hypertensive patients,PV and IPSS were higher in level 2 or 3 grade group than in level 1 group (F=6.890,7.576,all P＜0.01).PV and IPSS in high risk and very high risk groups were enhanced as compared with those in low-medium risk group (F=30.608,19.804,all P＜0.01).Pearson analysis showed that PV was positively correlated with SBP,FBG and TC(r=0.223,0.251,0.305,all P＜0.05),while negatively correlated with HDL-C(r =-0.235,P＜0.05).Similarly,IPSS was positively correlated with SBP,DBP and FBG (r=0.396,0.273,0.224,all P＜0.01),while negatively correlated with HDL-C (r =-0.288,P＜ 0.01).Conclusions High incidence of BPH appears in the elderly men with hypertension.The increased PV and IPSS coexist with conventional risk factors of essential hypertension.Development of BPH is closely related to higher blood pressure and risk stratifications of hypertension.
