Objective To compare the clinical effect of three different methods in treatment of premature.Methods 150 premature patients were randomly divided into three groups,50 cases for each group,received treatments with ritodrine,magnesium sulfate plus salbutamol,or magnesium sulfate alone respectively. The tensity of uterine contraction, the interval between drug administrations and the relief of uterine contraction, the accumulative drug using time, the elongated pregnancy durations were observed for the dertermination of effectiveness. Results The group treated with ritodrine, magnesium sulfate plus salbutamol or magnesium sulfate were effective in 94%, 78%,70% of patients of each group, and it showed that ritodrine was more effective than the combination and magnesium sulfate. The intervals of drug using and contraction relief were statistically different among three groups, (2. 16 ±0. 91)h,(4. 14 ± 1.07)h,(5.12 ± 1.45) h for each(all P ＜0.05).The cumulative drug using times were(7. 04 ±1. 16) d, (7.46 ± 1.20) d, (7.06 ± 2.78) d for three groups and proved not to be statistically significant ( all P ＞0. 05 ). The elongated pregnancy durations were (22.08 ± 7.32 ) d, ( 17.42 ± 5.85 ) d and ( 11.82 ± 5.04 ) d, and significantly different in three groups ( all P ＜ 0. 05 ). Conclusion The treatment of premature with ritodrine or the combination of magnesium sulfate and salbutamol was superior to using magnesium sulfate alone.

Objective To study the relationship between blood lipid levels, insulin therapy of pregnant women with abnormal glucose metabolism and perinatal outcomes. Methods 380 pregnant women who were diag-nosed and treated for abnormal glucose metabolism were enrolled in this study,including 24 cases with diabetes melli-tus(DM),164 eases with gestation diabetes mellitus (GDM), 192 cases with gestation impaired 81ucose tolerance (GIGT). Among the 380 cases, 136 cases were performed insulin therapy with diet controlling,244 cases diet control-ling. Results The incidence of pre-eclampsia and preterm labor in the DM group(41.7% and 41.7% )was higher than that in GIGT group(15.6% and 20.7%)and GDM group(15.9% and 18. 3%) (P<0.05). Among the three groups ,the incidence of macrosomia, polyhydranmios and fetal distress had no significant difference( P>0.05 ). While the incipience of neonatal asphyxia,hypoglycemia in the DM group were all higher than that in GDM and GIGT group ( P<0.01 ). The newborn weights in insulin therapy group( 2891.5±1330.4 g) was lower than that in diet controlling group(3751.2±1025.3 g) ( P<0.05 ). Conclusion The blood lipid level of pregnant women with gestational ab-normal glucose metabolism is one of the effective indexes to prognose perinatal outcomes. Reducing blood lipid levelcan decrease the incidence of pre-eclampsia and preterm labor,neonatal asphyxia and hypoglycemia significantly. Di-agnosing and beginning therapy as soon as possible and using insulin are important,especially to reduce the rate of macrosomia and newbem weights.

Objective To evaluate the results of direct anastomosis between the main pulmonary artery and right ventricle in the repair of complex congenital heart disease. Methods Between March 2001 and June 2004, seventeen patients with complex congenital heart disease underwent direct anastomosis between the main pulmonary artery and right ventricle. Among them, eleven patients were under 3 years old. Six patients had pulmonary atresia and ventricular septal defect (VSD), 4 had transposition of the great arteries and VSD, 4 persistent truncus arteriosus and 3 TOF with coronary artery straddling RVOT. Twelve patients underwent one stage complete corrective repair and 5 patients received staged procedures. Results There was 1 operative death with hospital mortality of 5.9%. Three out of 5 staged patients succeeded in the second corrective repair. At follow-up ranging from 1 to 40 months, all patients were growing well and their heart function were in NYHA class 0 or I. Conclusion Direct anastomosis between the main pulmonary artery and right ventricle can provide good results in the repair of certain complex congenital heart disease, especially in infant patients without suitable homograft.

Objective To evaluate the outcomes of one-stage repair of aortic coarctation (CoA) and associated cardiac anomalies in infants through a midline sternotomy. Methods Between June 2002 and August 2005, 36 patients (27male, 9 female) underwent surgery for CoA. The age was from 18 days to 8 years[mean (14.3?9.5) months], 27 patients (75%) were younger than 1 year and 18 patients (50%) were younger than 3 months. The body weight was from 3.0 to 23 kg [mean(6.6?3.0)kg]. 27 patients were symptomatic infants and 8 patients were asymptomatic of adults. One patient had recoarctation after repair through a left thracotomy one year ago. The associated cardiac anomalies included ventricular septal defect, patent ductus arteriosus, secundum atrial septal defect, hypoplasia of the aortic arch, transposition of great arteries and subaortic stenosis. 36 cases underwent one-stage operation of extended end-to-end anastomosis through a midline sternotomy. Results One patient died postoperatively with a mortality of 2.8 %. The cause of death was heart and lung function failure. 35 cases were followed up from 4 months to 3 years .One late death occurred. 34 cases were in good condition and no recoarctation. Conclusion Outcomes of one-stage repair of CoA and associated cardiac anomalies in infants through a midline sternotomy is excellent. Technique of extended end -to-end anastomosis may potentially reduce the incidence of recoarctation.

BACKGROUND: Central oxytocin (OT) may be a neurotransmitter or neuromodulator and play an important role in learning and memory, sexual behaviour, pain modulation and opiate tolerance and dependence. To research the interactions between oxytocinergic and opioidergic system in hippocampus has some significance.OBJECTIVE: To investigate the effects of OT administered intracerebroventricularly on evoked discharge of left dorsal hippocampal CA1 neurons in rats and the possible interactions between oxytocinergic and opioidergic system.DESIGN: A randomised controlled study.SETTING: Department of Physiology of Guangdong Medical College; Department of Physiology and Pathology of Medical College of Wuhan University.MATERIALS: The study was conducted in the Physiology Department of Medical College of Wuhan University from September 2002 to September 2003. A total of 36 male Sprague-Dawley rats were selected and randomly divided into six groups: control (NS), OT groups (0.2 mg/L, 2 mg/L and 20 mg/L), [d (CH2)5-OVT]+OT (2 mg/L), naloxone+OT (2 mg/L), with 6 rats in each group.METHODS: Single-unit recording was performed with glass microelectrode. The glass microelectrode was inserted by a micromanipulator into hippocampal CA1. The electrical activity was amplified by a microelectrode amplifier and then recorded by the biological experimental system,monitored at the same time with oscilloscope. When recording the neural discharge, electrical stimulation of the sciatic nerves was performed once 5minutes through a double stainless electrode. 5 μL oxytocin in dosage of 0.2, 2 and 20 mg/L were injected slowly into lateral ventricle via microlitre syringe. [d(CH2)5-OVT]+OT (2 mg/L) group: 2.5 μL [d(CH2)5-OVT](80 mg/L) was injected into lateral ventricle and then 2.5 μL oxytocin (2 mg/L). Naloxone+OT (2 mg/L) group: 2.5 μL naloxone (400 mg/L) was injected into lateral ventricle and then 2.5 μL oxytocin (2 mg/L). According to frequency of discharge, effect of oxytocin at various dosages on discharge induced by neurons in hippocampal CA1 area and [d (CH2)5-OVT]and naloxone on oxytocin was assayed. MAIN OUTCOME MEASURE: Changes of discharge frequency after stimulation.RESULTS: Data of totally 36 rats were entered the final analysis. ① OT (0.2 mg/L, 2 mg/L and 20 mg/L) administered by intracerebroventricularly could decrease the evoked discharge of hippocampal CA1 neurons in a dose-dependent manner. ② The inhibitory effects of OT (2 mg/L) could be blocked by pretreated intracerebroventricularly injection of [d (CH2)5-OVT](80 mg/L, 2.5 μL). ③ Intracerebroventricular injection of naloxone (400 mg/L, 2.5 μL) could attenuate the effects of OT (2 mg/L) significantly.CONCLUSION: OT can inhibit the electrical activities of hippocampal CA1 neurons to external electrical signal through activating the oxytocin receptor. Moreover, central opioid receptor is involving in the inhibitory effects of OT.

Background:Hepatic veno-occlusive disease( HVOD) is a disease characterized by hepatomegaly,jaundice, ascites,weight gain and lack of effective treatment currently. Our prophase research showed that ligustrazine had therapeutic effect on Sedum aizoon induced HVOD in mice. Aims:To investigate the mechanism of therapeutic effect of ligustrazine on Sedum aizoon induced HVOD in mice. Methods:A total of 115 mice were randomly divided into 4 groups:mice in group A were intragastrically administrated with 30 mg·kg-1 ·d-1 Sedum aizoon to induce HVOD and served as model group;mice in group B were given 30 mg·kg-1 ·d-1 Sedum aizoon + 100 mg·kg-1 ·d-1 ligustrazine and served as low dose ligustrazine intervention group;mice in group C were given 30 mg·kg-1 ·d-1 Sedum aizoon + 200 mg·kg-1 ·d-1 ligustrazine and served as high dose ligustrazine intervention group;mice in group D were given 30 mg·kg-1 ·d-1 PBS and served as normal control group. After 30 days,all the mice were sacrificed. HE staining and Masson staining were performed for histological examination. The mRNA and protein expressions of tissue factor(TF),nuclear factor(NF)-κBp65 and early growth response factor( Egr)-1 in liver tissue were determined by RT-PCR and Western blotting, respectively. Results:HE staining and Masson staining histological examination showed that ligustrazine could obviously ameliorate the pathological injury of liver tissue in HVOD mice. Compared with group D,the mRNA and protein expressions of TF,NF-κBp65,Egr-1 were significantly increased in group A( P < 0. 05). After intervention with ligustrazine,the mRNA and protein expressions of TF,NF-κBp65,Egr-1 were significantly decreased( P < 0. 05), especially in group C,and no significant differences were found between group C and group D(P > 0. 05). Conclusions:Ligustrazine has therapeutic effect on HVOD,the possible mechanism is that ligustrazine could interrupt the activation of coagulation system by reducing the expression of TF via down regulating the expressions of NF-κBp65 and Egr-1,especially in high dose ligustrazine group.
