Objective To study the genetic diversity of Sinopodophyllum hexandrum so as to provide basic molecular genetic evidence for protecting and exploiting the resource of S.hexandrum.Methods Six populations of S.hexandrum were analyzed by DALP molecular markers.To make up the genetic diversity correlation data by PopGene 1.31 software and cluster by UPGMA method,and establish the dendrogram.The tree was subsequently visualized with Treeview software.Results Five primer groups were screened and a total of 150 DNA fragments were amplified,among which 104 were polymorphic,i.e.the percentage of polymorphic bands(PPB) was 69.33%,the average number of DNA polymorphic band amplified by each primer group was 20.8 and the average PPB was 14.22%.In the six populations,the total observed number of alleles(Na) was 1.693 3 and the average Na was 1.142 2;The total effective number of alleles(Ne) was 1.417 1 and the average Ne was 1.083 8;The total Nei′s gene diversity(H) was 0.244 3 and the average H was 0.048 8;The total Shannon′s information index(I) was 0.364 3 and the average I was 0.073 0;The total gene diversity(Ht) was 0.244 3 while the gene diversity within a population(Hs) was 0.048 7.The coefficient of gene differentiation(Gst) was 0.800 5 between populations,namely 80.05% genetic variation occurring between populations and the rest 19.95% within population,and estimated gene flow(Nm) was 0.124 6.Conclusion The result indicats that S.hexandrum has much larger genetic differentiation among populations and gene flow has been blocked.This might be a result of species breeding system and population habitat.

Congenital diaphragmatic hernia (CDH) is one of the most common congenital malformations and the most deadly types of congenital disease.Pulmonary hypertension (PH) and pulmonary hypoplasia are the most important causes of determining the prognosis of CDH.The prenatal evaluation indicators and management of PH is a difficult point and hot issue of present international study.This article reviewed the new progress of pathogenesis,prenatal evaluation predictor,clinical diagnosis and treatment of CDH complicated with PH.

Objective To review and analyze the prenatal diagnosis and treatment of fetal bronchopulmonary sequestration (BPS).Methods Data of 68 BPS fetuses in the Department of Fetal Medicine,Guangdong Women and Children Hospital and Health Institute from January 20,2009 to January 31,2013 were reviewed.All of the 68 fetuses were diagnosed by ultrasound and volume to head circumference ratio (CVR) was measured.Postnatal surgeries at neonatal or infantile period were performed and babies were followed-up.Results With antenatal ultrasonography,fetal chest solid or hyper-echoic mass was found in all 68 cases at an average of 24 weeks of gestation (18-30 weeks) and were diagnosed as BPS after at least twice ultrasound scans.CVR was measured in these 68 cases,among them 56 cases (82.4％) were ＜1.6,and 12 cases (17.6％) were ≥1.6.Among the 12 cases with CVR≥1.6,seven developed fetal hydrops.Except for two terminated pregnancies because of CVR≥ 1.6 with fetal hydrops,all of the rest 66 cases continued their pregnancies till birth and 58 (87.9％) neonates were asymptomatic and eight (12.1％) were symptomatic.The mass was undetectable with ultrasonography in 18 fetuses during the third trimester,however,the mass was identifed again under CT scan after birth in 14 cases (another four cases unexamined).There were totally 45 cases fully recovered after lobectomy or BPS resection after birth,among which five cases underwent emergency surgery in neonatal period.Pathology results showed that 12 cases were intra-lobar and 33 cases were extra-lobar type.Totally,six cases were diagnosed as BPS under diaphragm.Sixty cases were followed up at three months to two years after birth,and all developed well and CT scan indicated normal pulmonary function.Conclusions Most BPS fetuses without hydrops have a good outcome.Fetus with BPS could wait for full term delivery following professional evaluation and standard protocol.However,the prognosis of BPS with fetal hydrops depends on prenatal evaluation and early surgical intervention.And the effect of early surgical intervention in BPS neonates is satisfied.CVR is the most important index for prenatal evaluation of BPS and CT scan after birth is critical for those babies with undetectable mass by prenatal ultrasound.

OBJECTIVETo explore the curative effect and safety of acupuncture for mild cognitive disorders after stroke.

METHODSRandomized controlled trial was adopted and one hundred cases conforming to criteria were divided into a combined acupuncture and medication group (group A) and a medication group (group B), 50 cases in each group. The basic treatment of cerebrovascular disease was applied in two groups. The group A treated was with acupuncture at Baihui (GV 20), Shenting (GV 24) and Qucha (BL 4) etc. and oral administration of Nimodipine. In group B, Nimodipine was taken orally. The treatment lasted for 3 months, the scores of Mini-Mental State Examination (MMSE), modified Hasegawa Dementia Scale (HDS-R) and Barthel Index (BI) were observed before and after treatment in two groups.

RESULTSThe total effective rate in group A was 66.7% (32/48), which was superior to 30.4% (14/46) in group B (P < 0.05). The scores of MMSE, HDS-R and BI after treatment were apparently improved as compared with those before treatment in two groups (all P < 0.01). The improvements in group A were superior to those in group B (all P < 0.05). There was no adverse event reported during the treatment in two groups.

CONCLUSIONAcupuncture can improve activity of daily living and has significant effect in treating mild cognition disorders after stroke without adverse reactions.
