The data were collected from 472 pregnant and parturient women in maternal system management at our center.All subjects were divided into the observation group (n =178 ) and the control group ( n =294) by the participation or non-participation of community management of maternal health.And the outcomes of pregnancy were analyzed for two groups.Compared with the control group,the observation group had a significantly higher correct rate of knowledge in maternal health ( P ＜ 0.01 ).The values of neonatal Apgar (5 min) score (9 ± 1 ) and breasffeeding rate (86.52％ ) increased while the caesarean rate (22.47％ ) declined (P ＜0.01 ).Community management of maternal healtb is effective in improving the pregnancy outcomes.

AimTo realize the regulatory actions of nitric oxide(NO) on supraoptic nucleus (SON) neurons by observing the effects of NO donor sodium nitroprusside(SNP) on SON neurons. Methods The cell electrophysioloical properties were obtained by the intracellular recording techniques from the SON neurons in adult rat hypothalamic slices. Results In 11 silent cells, superfusion of SNP(1 mmol · L-1) for 3～5 min resulted in the depolarization response with a decrease of membrane resistance and time constant(P＜0.05) in 55% of cells, while hyperpolarization with an increase of membrane resistance in 45 % of neurons. In 73% of tested cells, SNP also decreased the amplitude, overshoot, firing frequency and slope of current-voltage curve, and increased the afterhyperpolarization of action potentials evoked by intracellular depolarizing current pulses(P ＜0.05).However, SNP enhanced the spontaneous firing in 67% of 6 tested cells with spontaneous activities. ConclusionSNP presents an inhibitory or excitatory effect on SON neurons in aneurontype-andfunctionalstate-dependent manner, which suggests that NO may exhibit adverse regulatory actions on SON neurons.

Aim To realize the modulatory actions of nitric oxide(NO) on supraoptic nucleus(SON)neurons by observing the effects of NO donor sodium nitroprusside(SNP) on the SON neurons. Methods The cell electrophysiology properties were obtained by the intracellular recording techniques from the SON neurons in adult rat hypothalamic slices.

Objective To study the diagnosis and treatment of primary liver cancer(PLC) with bile duct cancer thrombus (BDT). Methods The clinical data of 21 patients with PLC and BDT admitted in the past 8 years were analyzed retrospectively . Results The major clinical manifestations were the symptoms of primary liver cancer and obstructive jaundice. The correct diagnosis rate was 76.2% before operation. The diagnosis rate of B-us, CT, MRI, ERCP and PTC was 14.3%, 9.52%, 14.3%, 71.4% and 100% respectively. The operative procedures included hepatectomy with removal of BDT ( n =10), hepatectomy combined with extrahepatic bile duct resection ( n =5), thrombectomy through choledochotomy with TACE ( n =3), removal of BDT with HAI ( n =3). The 3,5-year survival rate were 43.20% and 24.60% respectively. Conclusions Multi-examinations should be applied in the diagnosis of PLC with BDT. The comprehensive therapy including surgery and other therapies must be adoptted for PLC with BDT.

Objective To explore the distribution of parvovirus B19 (HPVB19) infection in patients with leukopenia.Methods Patients who visited the Affiliated Hospital of Hangzhou Normal University from January 2015 to June 2016 were analyzed.Patients with peripheral leucocytes count less than 3.5×109/L were included in experiment group and healthy people were included in control group.HPVB19 IgG and IgM were detected by enzyme-linked immunosorbent assay, and HPVB19 DNA was detected by quantitative polymerase chain reaction.Differences in continuous data between two groups were compared with two-sample t test and those in categorical data were compared with Chi-square test.Results A total of 79 patients were included in experiment group, including 32 males and 47 females.Ages ranged from 24 to 62 years old.And 126 healthy individuals were included in control group, including 55 males and 71 females.Ages ranged from 28 to 67 years old.The positive rates of HPVB19 IgG, IgM and DNA in experiment group were 34.2%, 5.1% and 3.8%, respectively, while those in control group were 36.5%, 0 and 0, respectively.The detection rates of HPVB19 IgM and DNA between two groups were significantly different (χ2=6.507, P=0.011 and χ2=4.856, P=0.028, respectively).Sequence analysis for 3 of the HPVB19 DNA positive samples showed that there were two single nucleotide polymorphisms in VP1/VP2 sequence from one patient, which contributed to the 153rd (L/H) and 219th (N/Y) amino acids mutations, respectively.Phylogenetic analysis found that two strains belong to genotype 1a and one strain belongs to genotype 1b.Conclusions Detection rate of parvovirus HPVB19 infection (positive rates of HPVB19 IgM and DNA) in leukopenic patients is significantly higher than healthy controls.HPVB19 should be detected before considering transfusion in leukopenic patients in clinical practice.

Objective To observe the effects of nebulized nitric oxide donors on pulmonary and systemic hemodynamics during pulmonary hypertension induced by hypoxia (FiO_2=0.1,for 1 hour)in newborn piglets. Methods Twenty-four anesthetized and mechanically ventilated piglets were randomly divided into four groups:(1)group S (n=6),control group;(2)group C (n=6),receiving saline after hypoxia;(3)group NTG,receiving nebulized nitroglycerin after hypoxia;(4)group SNP,receiving nebulized sodium nitroprusside after hypoxia. Mean arterial pressure (MAP)and mean pulmonary arterial pressure (MPAP)were monitored continuously. Arterial blood gas analysis was determined at baseline,1 hour after hypoxia,termination of nebulization and 0.5 h after nebulization. After nebulization,blood methemoglobin (MetHb)and plasma NO level were measured.Results Acute hypoxia resulted in a significant increase in MPAP. At 1 hour after hypoxia,MPAP in group C,group NTG and group SNP were significantly higher than that in group S(P0.05).After nebulization,there were no significant differences in plasma NO level and blood MetHb level between groups. No rebound pulmonary hypertension was observed after withdrawal of nebulization. Conclusion Both NTG and SNP nebulization could be used as selective pulmonary vasodilators for acute hypoxic pulmonary hypertension.
