A report of 42 patients with type Ⅲ biliary atresia treated by hepatojejunostomy / 中华肝胆外科杂志

Objective To determine the clinical effects of type Ⅲ biliary atresia treated by hepatojejunostomy (Kasai procedure).Methods A retrospective study was performed on patients with type Ⅲ biliary atresia treated in our hospital between January 2009 to December 2013.Results The follow-up data were completed in 42 patients out of 48 patients (87.5％) who underwent Kasai procedure for type Ⅲ biliary atresia.The jaundice disappeared in 31 of 42 patients (73.8％).The rate of patients having cholangitis was 47.6％.There were significant differences in the 2-year survival among the groups of patients with mild cholangitis (75.0％,9/12),serious cholangitis (25.0％,2/8) and without cholangitis (86.4％,19/22) (P ＜ 0.05).Conclusions Hepatojejunostomy (Kasai procedure) is an effective operation to treat type Ⅲ biliary atresia.Our data suggested that the survival rates were related to the degree of bile drainage and cholangitis post surgery.

<p><b>OBJECTIVE</b>To study the chemical constituents of Hemsleya chensnsis.</p><p><b>METHOD</b>Various chromatographic techniques were used to separate and purify the constituents. The spectral data (MS, NMR) were obtained for structure elucidation.</p><p><b>RESULT</b>Eight known triterpenoid saponins were isolated from the root of H. chensnsis. Their structures were elucidated as dihydrocucurbitacin B (1), 25-O-acetyl-dihydrocucurbitacin F (2), cucurbitacin F (3), 3-O-(6'-ethyl ester) -beta-D-glucuropyranosyl oleanolic acid-28-O-alpha-L-arabinopyranoside (4), oleanolic acid-3-(6'-methyl ester) -beta-D-glucuropyranosyl (1-3) -alpha-L-arabinopyranoside (5), oleanolic acid-28-O-beta-D-glucopyranosyl-(1-6) -beta-D-glucopyranoside (6), 3-O-(6'-methyl ester) -beta-D-glucuropyranosyl oleanolic acid-28-O-beta-D-glucopyranosyl-(1-6) -beta-D-glucopyranoside (7), 3-O-(6'-methyl ester) -beta-D-glucuropyranosyl (1-2) -beta-D-glucopyranoside-oleanolic acid-28-O-beta-D-glucopyranoside (8).</p><p><b>CONCLUSION</b>All compounds except for 2 were isolated from H. chensnsis for the first time.</p>

Genetic structure analysis of cultivated Scrophularia ningpoensis in Zhejiang Province / 中草药

Objective To observe the genetic structure of cultivated Scrophularia ningpoensis in Zhejiang Province.Methods The genetic structures of six typical S.ningpoensis populations were analyzed by fluorescence AFLP marker.Results Bands(12 552) were generated by seven pairs of AFLP primer combinations,of which 8 808 were polymorphic,and the polymorphic rate was 70.17%.The variety ranges of PPB among different populations were 41.67%—55.56%,and 47.30% in average.I was between 0.190 8—0.238 3,and 0.221 8 in average.Ne was between 1.201 4—1.280 6,and 1.236 9 in average.Gst was 0.127 1,Nm was 3.432 4.UPGMA Cluster analysis showed that the six populations can be divided into two clusters,as that of Tiantai,Jinyun,and Jingning were one sub-cluster,and Dongyang,Pan′an,and Xianju were another one sub-cluster.Conclusion There is a relative high genetic diversity level in cultured S.ningpoensis of Zhejiang Province.Genetic differentiation exists among populations,but it exists in population mostly.There is a relative high genetic intercommunion among populations.The genetic distance is not related to the geographic environment.

AFLP Analysis on genetic diversity for germplasm resources of Fritillaria thunbergii cultivated in Zhejiang Province / 中草药

Objective To study the genetic diversity of Fritillaria thunbergii,a traditional Chinese herb in Zhejiang Province in China.Methods The genetic diversity of six representational populations of F.thunbergii including 32 individuals was investigated by amplified fragment length polymorphism(AFLP) maker technique.Results The genetic diversity was revealed as follow: the Nei′s genetic diversity index(He) 0.169 0?0.175 7,Shannon′s information index(I) 0.269 8?0.245 3,percentage of polymorphic loci(PPB) was 76.85% at the species level;Ht 0.169 0?0.030 9,and Hs 0.150 8?0.024 0,I 0.233 3?0.261 9, PPB was 50.38% at population level.The genetic differentiation index(Gst) was 0.107 6,Nm 4.147 0.The result of dendrogram of six populations indicated that Dongyang and Yongkang populations shared the minimum genetic distance(0.015 0),they were classified into a group,and Xiangshan and Jinyun populations shared the maximum genetic distance(0.032 4).Conclusion The genetic diversity of F.thunbergii cultivated in Zhejiang Province is very rich,which could ensure the long-term survival of F.thunbergii.But the genetic diversity of F.thunbergii is relatively higher in population levels while lower at the species levels and the degree of genetic differentiation occured among the populations is not significant.The germplasm resources are relatively stable among these six populations.These populations could be used to breed the fine strains of F.thunbergii as the bases.
