Objective To study the association of apolipoprotein ( Apo) E gene polymorphism with difference in biochemical metabolism of diabetic nephropathy of Hui and Han populations. Methods ApoE genotype was determined by PCR-RFLP in diabetic patients with or without diabetic nephropathy (DN) and normal peoples in Hui and Han peoples, the related biochemical parameters were simultaneously detected. Results (1) Huis had 3 genotypes, i. e. E2/E3, E3/E3 and E3/E4, and their frequencies were 0. 043, 0. 894 and 0. 064, respectively. Hans had 5 genetypes, i. e. E2/E2, E2/E3 , E2/E4, E3/E3 and E3/E4, and their frequencies were 0.075,0.060, 0.164, 0.642 and 0.060, respectively. The frequencies of 3 alleles, E2, E3 and E4, in Huis and Hans were 0.021, 0.947, 0.032 and 0.187, 0. 702, 0.112, respectively. The results showed that difference in frequencies of genotypes and alleles of Huis and Hans was very significant (both P

Purpose:To study the effects of hydroxycamptothecin with thermotherapy on anti-angiogenesis in vitro and in vivo. Methods:We chose human microvascular endothelial cell (HMVEC) culture and chick embryo choriallantoic membrane (CAM) model and used MTT and number-calculating methods to observe hydroxycamptothecine on HMVEC’s proliferation , sprouts and CAM blood vessels’ formation.Results:The survival rate of endothelial cells was in the range of (68.2%)-44.7% within the dose of 20-40 ng/ml and 5-80 ng/ml and was negatively correlated with the concentration (correlation coefficient was -0.906,-0.469,P=0.00003,0.0051). Hydroxycamptothecine could significantly suppress the endothelial cells’ proliferation and the sprouts. Hydroxycamptothecine could significantly suppress CAM vessels. The survival rate of HepG II cells is in the range 100%-90% within the dose of 5-80 ng/ml. There was no cytotoxicity.There was a synergestic anti-angiogenetic effect when hydroxycamptothecin (20 ng/ml) was combined with thermotherapy in vitro while there was additive effect when hydroxycamptothecin (40 ng/ml) was combined with thermotherapy in vitro.Conclusions:This experiment shows that small doses of hydroxycamptothecine (20-40 ng/ml) with thermotherapy has anti-angiogenetic synergestic or additive effect on proliferation and migration both in vivo and in vitro.

Objective To investigate the effect of postnatal music exposure on fearful behavior of prenatal stressed rats in defensive withdrawal test and the expression of gastrin-releasing peptide receptor (GRPR) in the amygdala. Methods Wistar pregnant rats were divided in stress group (n=8) and control group (n=8). The stress group were immobilized and bright lighted 45 min, 3 times a day, when gestation 11-20 days, while the control group without any stress. The new born rats from the stress group were exposed in music (SM group) or white noise (SW group) for 45 min twice a day since 1 day after born, and the rats from the control (SC) group left undisturbed. They were tested with defensive withdrawal test 60 days after birth, and the GRPR levels in the amygdala were measured with immunofluorescence and real-time PCR. Results The latency was shorter and the frequence out of the chamber was the most in the SM group of the defensive withdrawal test (P<0.001), while GRPR-positive cells and GRPR mRNA increased in amygdala (P<0.001). Conclusion Postnatal music exposure can counteract the abnormal behavior response of prenatal stressed offspring and accompany with increased expression of GRPR in the amygdala.

Objective To investigate clinical predictors in early pregnancy for adverse pregnancy outcomes in women complicated with chronic nephropathy. Methods One hundred and eighty-four pregnancies complicated with chronic nephropathy who delivered between January, 2005 and January, 2014 in Peking University First Hospital were retrospectively analyzed. Two hundred pregnant women without chronic nephropathy were selected as the control group. Pregnancy outcomes were compared between the two groups. Relationships between clinical predictors in early pregnancy [age, history of kidney disease, drugs used before pregnancy (in three months), results of renal biopsy, blood pressure, serum creatinine, urea nitrogen, 24 h urinary protein, estimated glomerular filtration rate, stage of chronic nephropathy] and adverse pregnancy outcomes [maternal mortality;pregnancy complicated by severe preeclampsia;renal function decline, early preterm birth, very low birth weight infants, fetal loss after 20 weeks of pregnancy] were assessed by logistic regression analysis. T-test, Chi-square test and multivariate regressions were used for statistical analysis. Results There were 174 and 197 livebirths in the study and the control groups, respectively. The most popular type of chronic nephropathy in pregnant women was IgA nephropathy (38.6%, 71/184). Compared with the control group, the risk of premature labor [9.8%(17/174) vs 3.0%(6/197), χ2=7.184], low birth weight infants[18.4%(32/174) vs 7.1%(14/197),χ2=9.813], very low birth weight infants [5.7%(10/174) vs 1.5%(3/197),χ2=4.536], fetal loss after 20 weeks of pregnancy [5.7%(10/184) vs 1.5%(3/200), χ2=4.536] and severe preeclampsia [17.9%(33/184) vs 1.5%(3/200), χ2=33.544] increased significantly in the study group (all P < 0.05). Twenty-four-hour urinary protein content (OR=1.84, 95%CI: 1.36-2.50, P=0.001) and mean arterial pressure (OR=1.04, 95%CI: 1.00-1.07, P=0.027) in early pregnancy were risk factors for adverse pregnancy outcomes. The risk of renal function decline increased significantly in patients with higher stages of chronic nephropathy in early pregnancy (OR=6.50, 95%CI: 3.34-8.21, P<0.01). Mother complicated by preeclampsia during pregnancy was an independent risk factor (OR=11.10, 95%CI: 4.48-27.20, P<0.01). Compared with women whose 24 h urinary protein content less than 1g in early pregnancy (122 livebirths within 126 cases), the risk of premature labor [17.3%(9/52) vs 6.6%(8/122), χ2=4.780], increased significantly in women whose 24 h urinary protein content were more than or equal to 1 g in early pregnancy (52 livebirths within 58 cases) (P<0.05). Conclusions Elevated urinary protein level and mean arterial pressure in early pregnancy were risk factors of adverse pregnancy outcomes. The risk of renal function decline increased in patients with higher stages of chronic nephropathy in early pregnancy. Mother complicated by preeclampsia during pregnancy was an independent risk factor for poor prognosis of the fetus.

Physiology course has become an important teaching part of non-medical professions in medical colleges,but there are no normative teaching textbooks and the corresponding teaching syllabus for these non-medical professions,which causes teaching contents chaos and affects the teaching effect.According to their attributes and characteristics,the research group explores continuously the physiology teaching contents suitable for non-medical professions,pays attention to contents settings which are common-sense,practical,systematic and flexible,in order to promote physiology teaching development in non-medical professions.

Objective To explore the analgesic effect of ropivacaine combined with sufentanil in epidural anesthesia on walk on painless labor.Methods 134 cases of maternal pregnancy were selected and randomly divided into two groups.61 cases were treated with conventional delivery,73 cases in the experiment group were treated with walk on painless labor.The visual analogue scale and improved Bromage classification score were compared at the first stage of labor,the second stage of labor,the third stage of labor.Results Compared with the control group,the rate of cesarean section was higher(P<0.05),The visual analogue scale was higher at the first stage of labor,the second stage of labor,the third stage of labor,the duration of labor were lower at the first stage of labor,the second stage of labor,the third stage of labor(P<0.05),and there was no significant difference between the two groups in the motor nerve block.Conclusion Ambulatory labor analgesia on maternal effect significantly,can significantly reduce the pain degree of maternal birth process and deliverry time,postpartum less complications.

Established rat models with subclinical hypothyroidism (SCH) were divided into three groups:subclinical hypothyroid(SCH),SCH treated with levothyroxine (L-T4),and control group.The L-T4 group displayed lowered total cholesterol and endothelin levels compared with the SCH group[(1.29 ±0.05 vs 2.38 ±0.55) mmol/L,(98.54 ± 32.43 vs 160.62 ±37.25) nmol/L,both P＜0.05].Nitric oxide levels,left ventricular systolic pressure,and blood flow in abdominal aorta were significantly higher in the L-T4 group than those in the SCH group.The results of this study indicate that L-T4 treatment may improve endothclial dysfunction and hemodynamic changes in rats with SCH.
