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.

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.

AIM:To investigate the differences among Lenstar 900, A-scan ultrasound and keratometer in measurement of axial length ( AL ) , anterior chamber depth ( ACD ) and corneal curvature ( K1 , K2 , Km ) , and evaluate the consistency of the instruments, with the purpose providing references for the clinical application of Lenstar 900.
METHODS: In this study we picked up 36 patients ( 50 eyes ) underwent cataract surgery, and lens nucleus hardness were under level IV. Before the operation, AL, ACD and K1 , K2 , Km were measured by Lenstar 900, A-scan ultrasound and keratometer respectively. The differences between the results were compared by the paired t-test. The correlation of the results was analyzed by Pearson correlation analysis, and the consistency was measured by Bland-Ahamn method.
RESULTS: The mean AL and ACD values measured by Lenstar 900 and A-scan ultrasound had no significantly statistic differences (P>0. 05). The K1, K2, Km measured by Lenstar 900 and keratometer were not significantly statistical different (P>0. 05). The results measured by these three instruments had close linearity correlation ( r>0.9, P<0. 01). The consistency of the results was well in Bland-Ahamn analysis.
CONCLUSION:The preoperatively biometric result of Lenstar 900, A - scan ultrasound and keratometer in patients with cataract are all reliable, and they can be substituted by each other. However, Lenstar 900 can not only measure AL, ACD and corneal curvature at the same time, but also cornal thickness, lens thickness, white to white, pupil size, optical axis eccentricity, retinal thickness and so on. It has a number of advantages such as non-touching, convenient and efficient, and can be recommended to use widely.
