Objective To investigate the effect of Astragalus injection combined with low molecular weight heparin and nifedipine on levels of related indexes and pregnancy outcomes in patients with preeclampsia.Methods A total of 60 patients with preeclampsia from March 2013 to December 2016 in Cixi Municipal Maternal and Child Care Hospital were selected and randomly divided into the study group and control group, with 30 cases in each group.All patients were given spasmolysis, diuretic and other conventional treatment.The control group were treated with low molecular weight heparin and nifedipine while the study group were additionally treated with Astragalus injection.The blood pressure, blood coagulation and other laboratory indicators in the two groups were monitored before and after treatment , and the incidence of pregnancy complications and pregnancy outcomes in the two groups were statistically analyzed.Results There was no significant difference in blood pressure, human chorionic gonadotropin (β-hCG), alpha fetoprotein (AFP) and blood coagulation function indexes in the two groups before treatment .After treatment, the blood pressure,β-hCG, AFP, platelet count (PLT), prothrombin time (PT), activated partial thromboplastin time (APTT), plasma fibrinogen (FIB) and D-dimer (D-D) were significantly improved, the difference was statistically significant ( P<0.05).After treatment, the diastolic and systolic blood pressure, β-hCG, AFP, PLT, FIB and D-D levels in the study group were significantly lower than those in the control group, the difference was statistically significant ( P<0.05), PT and APTT were significantly longer than those in the control group, the difference was statistically significant (P<0.05).The incidence rates of pregnancy complications ( uterine inertia, premature rupture of membrane, fetal distress, placental abruption) and adverse pregnancy outcomes (cesarean section, neonatal asphyxia) in the study group were significantly lower than those in the control group, the difference was statistically significant (P<0.05).Conclusion The application of Astragalus injection combined with low molecular weight heparin and nifedipine in the clinical treatment of patients with preeclampsia can effectively control the blood pressure level and other parameters , reduce pregnancy complications and improve pregnancy outcomes.

Aim To explore the effects of acupuncture and sinomenine on the withdrawal symptoms,on the spontaneous discharge and synaptophysin expression of amygdala of heroin-addicted rats.Methods 75 SD rats were randomly and equally divided into 5 groups consisted of control,heroin-addicted,acupuncture,sinomenine and combined treatment group.The model of heroin-addicted rats were established with heroin subcutaneous injection,which in acupuncture,sinomenine and combined group were subsequently punctured at 3 acupoint(Neiguan,Baihui and Zusanli),intramuscular injected with sinomenine and treated with combined methods(acupuncture and sinomenine)respectively.The withdrawal symptoms of rats in different group were evaluated,and then the spontaneous discharges and synaptophysin expression of amygdala were detected with electrophysiological and immunohistochemical technology respectively.Results The heroin-addicted rats were successfully established,being suggested by typical withdrawal symptoms induced by naloxone(P<0.01 vs control),which were alleviated in the 3 treatment groups(acupuncture,sinomenine and combined ) with varying degree(P<0.01 vs heroin group).The electrophysiological results suggest that the forms of low-frequency and single irregular discharges in amygdala were increase,bunchy/cluster and complex discharges were decreased(P<0.05 vs control),which were reversed apparently in sinomenine and combined treatment groups(P<0.05 vs heroin group),closed to control.The immunohistochemical results show that expression of synaptophysin in amygdala was increased obviously(P<0.01 vs control),which was decreased in the 3 treatment groups(acupuncture,sinomenine and combined),P<0.01 vs addicted group.Conclusion Treatments of acupuncture and sinomenine administration can alleviate withdrawal symptoms of heroin-addicted,and rectify the abnormal spontaneous discharges and expression of synaptophysin in amygdala of heroin-addicted rats for certain degree,especially with combined treatments.

Objective To evaluate the effects of strict dietary salt restriction on blood pressure and proteinuria in chronic glomerulonephritis (CGN) patients. Methods From October 2007 to April 2009, 32 CGN inpatients were enrolled. Among them, 15 patients followed a strict dietary salt restriction menu (sodium 100 mmol/d, potassium 50 mmol/d, protein (0. 8-1. 0) g · kg~(-1) · d~(-1) , calorie (105-125) KJ · kg~(-1) · d~(-1) ) for 7 days, while the other 17 patients were fed freely offered by hospital as controls. 24 h urinary sodium excretion (24h-UNa) was used to monitor the salt intake. No changes of drug therapy were made during the study. Blood pressure was monitored every day. 24-hour urinary protein and serum biochemical parameter were measured before and after the study. Results There was no significant difference of baseline 24h-UNa between the two groups [(135.1 ±50.4) mmol/d vs (137.4 ±28.6) mmol/d) ]. During the study, the average 24h-UNa of patients with strict dietary intervention was (97. 2 ± 8.6) mmol/d. Both SBP [ (117. 7 ± 10. 0) mm Hg( 1 mm Hg=0. 133 kPa) vs (106.2 ±9.9) mm Hg] and DBP [ (76. 3 ± 6. 1 ) mm Hg vs (67. 5 ± 5. 5 ) mm Hg] decreased significantly ( P < 0. 001 ) . Proteinuria decreased significantly too [ 1. 57 (0. 3-3. 0) g/d vs 0. 57 (0. 16-2. 72) g/d,P = 0. 006]. The reduction of SBP was positively correlated with the reduction of 24h-UNa (r =0. 572, P =0. 026) , while the reduction of proteinuria correlated with both the reduction of SBP (r = 0. 568, P = 0. 027) and 24h-UNa (r =0. 525, P =0. 044). In the control group, only SBP decreased significantly [ ( 122. 6 ± 15. 5) mm Hg vs (115.8 ±10.4) mm Hg, P = 0.02] without significant changes of DBP and proteinuria When comparing the subgroups who took ACEI/ARB from both groups, the reduction of proteinuria wasmore prominent of those from the study group than the control group [ - 0. 4 ( -0. 95-0. 07) vs 0. 07 ( - 0. 39-0. 42), P = 0. 014 ]. Conclusion Strict dietary salt restriction is effective in reducing blood pressure and proteinuria in CGN patients.
