Objective:To determine levels of insulin and glucose of maternal serum (MS),umbilical venous serum (UVS) and umbilical artery serum (UAS) in normal term pregnancy and intrauterine growth retardation(IUGR).Methods:One hundred and seven cases of normal gestational weeks on induction of labors and spontaneous deliveries and 32 cases of pregnancies complicated with IUGR.Levels of insulin were measured with sensitive radioimmunoassay and levels of glucose were measured by the glucose oxidase-peroxidase method.Results:Level of insulin of maternal serum was not significantly different before 28 gastational weeks and peaked on 28 th gastational week,then it decreased with gestational weeks and peaked again at last term.Levels of insulin increased in UVS and UAS.Levels of glucose in MS,umbilical venous serum and umbilical artery serum were not significantly different.Level of insulin and glucose of MS in IUGR had no change,but it was significantly different in IUGR of UVS and UAS (P<0.01).Conclusion:Our study suggested a decrease of insulin and glucose in UVS and UAS with IUGR.

Objective To study the effects of PM2.5 on reproductive hormone levels and pregnancy outcome in female rats.Methods Thirty healthy 4-week old female Sprague-Dawley rats were randomly divided into the control group (normal saline), low dose of PM2.5(1.5 mg/kg) group and high dose of PM2.5 (37.5 mg/kg) group.After the blood samples were collected, the animals were exposed to PM2.5for 10 days, and then the rats were mated.On the 19th day of pregnancy, the rats were sacrificed for pregnancy outcome observation and blood samples were collected for hormone test.The blood hormone levels were detected using an ELISA kit.Results The live fetus rates in the control, low dose PM2.5 and high dose PM2.5 groups were 90.77%, 59.49% and 60.27%, respectively (P<0.05).The live fetus rates in the low dose PM2.5 and high dose PM2.5 groups were significantly lower than that in the control group (P<0.05).PM2.5decreased the levels of E2, PROG, CG and LH (P<0.05), compared with that in the control group.Although the blood levels of FSH were not significantly different between the low dose and control groups (P>0.05), the level of FSH in the high dose group was significantly decreased (P<0.05).Conclusions PM2.5may affect pregnancy outcome through influencing the hormone levels.

Objective To study the effect of interventional treatment of iliac and femoral vein stenosis concomitant with deep venous thrombosis. Method Fifty-three patients were divided into 5 groups. In group A after placing into inferior vena cava a filter,11 patients adopted Amplatz Trombectomy Device for thrombolysis or ORSIS thrombolysis and persistent thrombolysis through popliteal vein. In group B thrombus was taken out through guiding catheter and then persistent thrombolysis through popliteal vein after placing into inferior vena cava filters in 9 cases. In group C 13 patients adopted persistent thrombolysis through femoral arteries. In group D 8 patients received persistent thrombolysis through popliteal vein. In group E persistent thrombolysis through foot veins was carried out in 12 patients. Seventeen patients received implanted stents and balloon-expansion in iliac and femoral veins. Results Symptoms disappeared in 26 patients(49.0%), significantly improved in 21 patients (39.6%), improved in 3 patients (5.7%), did not improve in 3 patients (5.7%), respectively. The repatency of iliac and femoral vein was achieved in more than 80% of the 17 patients. Complications developed in 3 cases in the course of thrombolysis. Conclusion The effect of mechanical removal of thrombus, persistent thrombolysis through catheter and transluminal angioplasty is safe and satisfactory.

OBJECTIVE To clarify whether the thera-peutic effect of escitalopram on depression patients is cor-related with traditional Chinese medicine syndrome types,and to provide a basis for more accurate drug applica-tion.METHODS A total of 235 depression patients were recruited and classified according to traditional Chinese medicine syndrome differentiation into 5 types:liver and qi stagnation(45),liver stagnation and fire transformation(43),liver qi stagnation and spleen deficiency(79),heart and spleen deficiency(20),and liver and kidney deficiency(38).All patients were treated with escitalopram(10 mg·d-1)for eight weeks.The Montgomery Depression Rating Scale(MADRS)and the 17 Hamilton Depression Rating Scale(HAMD-17)were used to score before treatment and 2,4,and 8 weeks after treatment,respectively.RESULTS Compared with before treatment,the MADRS and HAMD-17 scores and remission rates of each syn-drome type significantly improved with increasing medica-tion duration.The MADRS score relief rate of liver and kidney deficiency type was the most significant(69.3%),significantly higher than the other four syndrome types(47.5%-52.6%,P<0.05);The remission rate of HAMD-17 score was significantly higher than that of heart and spleen deficiency(50.7%vs.28.5%,P<0.05).The remis-sion rate of HAMD-17 score in liver and qi stagnation type(52.2%)was significantly higher than that in liver stagnation and spleen deficiency type(37.0%,P<0.01)and heart spleen deficiency type(28.5%,P<0.05).CON-CLUSION Escitalopram may have a more significant therapeutic effect on patients with liver and kidney defi-ciency and liver stagnation depression.This study pro-vides a new approach for the more effective and accu-rate application of traditional Chinese medicine syndrome differentiation in the selection of clinical antidepressants.
