Objective To investigate the application of admission test as a medical management in the labor room.Methods Eight hundred and fifty singleton pregnant women underwent admission test in labor room at Women's Hospital,School of Medicine,Zhejiang University from Dec.2009 to Dec.2011 were enrolled into this study.They were divided into two groups:normal group (admission test was normal,n =658) and abnormal group (admission test was abnormal or undetermined,n =192).Deliveries and perinatal outcomes of them were observed.The difference between the two groups were compared with two independent sample t test and Chi-square test.Results There were no significant differences in the mean age at delivery of the women and mean birth weight of neonates between the two groups (all P>0.05).The cesarean section rate of normal group (34.2%,225/658) was lower than that (59.4%,114/192) of abnormal group (x2=3.93,P<0.05).The rates of prematurc rupture of membranes (72.4%,139/ 192),fetaldistress (42.2%,81/192),neonatal asphyxia (16.5%,27/192) and neonatal complications (31.8%,61/192) in abnormal group were significantly higher than those [31.0% (204/658),24.2% (159/ 658),0.2%(1/658) and 2.6% (17/658)] in normal group (x2 =105.78,40.84,52.54 and 151.92,P<0.01respectively).Conclusions Admission test is a good method to forecast placental function during labor and perinatal outcomes,which might play an important role in medical management in labor room.

In order to identify Aucklandiae Radix, Vladimiriae Radix, Inulae Radix, Aristolochiae Radix and Kadsurae Radix using ITS2 barcodes, genomic DNA from sixty samples was extracted and the ITS2 (internal transcribed spacer) regions were amplified and sequenced. The genetic distances were computed using MEGA 5.0 in accordance with the kimura 2-parameter (K2P) model and the neighbor-joining (NJ) phylogenetic tree was constructed. The results indicated that for Aucklandiae Radix (Aucklandia lappa), Vladimiriae Radix (Vladimiria souliei and V. souliei var. cinerea), Inulae Radix (Inula helenium), Aristolochiae Radix (Aristolochia debilis) and Kadsurae Radix (Kadsura longipedunculata), the intra-specific variation was smaller than inter-specific one. There are 162 variable sites among 272 bp after alignment of all ITS2 sequence haplotypes. For each species, the intra-specific genetic distances were also smaller than inter-specific one. Furthermore, the NJ tree strongly supported that Aucklandiae Radix, Vladimiriae Radix, Inulae Radix, Aristolochiae Radix and Kadsurae Radix can be differentiated. At the same time, V. souliei (Dolomiaea souliei) and V. souliei var. cinerea( D. souliei var. cinerea) belonging to Vladimiriae Radix were clearly identified. In conclusion, ITS2 barcode could be used to identify Aucklandiae Radix, Vladimiriae Radix, Inulae Radix, Aristolochiae Radix and Kadsurae Radix. Our study may provide a scientific foundation for clinical safe use of the traditional Chinese medicines.

In this paper, the chloroplast psbK-psbI intergenic spacers of 18 species of Dendrobium and their adulterants were amplified and sequenced, and then the sequence characteristics were analyzed. The sequence lengths of chloroplast psbK-psbI regions of Dendrobium ranged from 474 to 513 bp and the GC contents were 25.4%-27.6%. The variable sites were 71 while the informative sites were 46. The inter-specific genetic distances calculated by Kimura 2-parameter (K2P) of Dendrobium were 0.006 1-0.058 1, with an average of 0.028 4. The K2P genetic distances between Dendrobium species and Bulbophyllum odoratissimum were 0.093 2-0.120 4. The NJ tree showed that the Dendrobium species can be easily differentiated from each other and 6 samples of the inspected Dendrobium species were identified successfully through sequencing the psbK-psbI intergenic spacer. Therefore, the chloroplast psbK-psbI intergenic spacer can be used as a candidate marker to identify Dendrobium species and its adulterants.

This study aimed to amplify major genome segments (VP7, VP4, VP6, VP2 and NSP2-5) of porcine G3 group A rotavirus (GARV) LLZ212 isolated in our laboratory, determine their genotypes, and explore the evolutionary relationships between G3 GARV strains isolated from humans and pigs in Lulong County, Hebei Province, China. Major genome segments of seven GARV strains were amplified by reverse transcription-polymerase chain reaction (RT-PCR) and the segments were sequenced. The genome segments of seven GARV strains were determined by the online RotaC genotyping tool (RotaC v2.0). The reference sequences of each GARV genome segment were downloaded from GenBank. Homology and phylogenetic evolutionary analyses were conducted using the MEGA 5.0 and DNAStar software packages. LLZ212 isolated from pigs in Lulong had the following genotype: G3-P[8]-I5-C1-N1-T1-E1-H1. All human GARV strains had the following genotype: G3-P[8]-I1-C1-N1-T1-E1-H1. The VP7, VP4, NSP4 and NSP5 genes of the LLZ212 strain had the highest nucleotide identities with the human GARV E885, CMH014/07, Wa and RMC321 strains, respectively, and these clustered together in a sublineage. The VP6, NSP4 and NSP5 genes of the LLZ212 strain shared the highest nucleotide identities with the porcine GARV PRG921 strain, while VP2 associated most closely with porcine GARV OSU strain, and these also clustered in a sublineage. A rare porcine G3-P[8]-I5-C1-N1-T1-E1-H1 GARV strain was identified, which may represent a reassortment between porcine and human viruses. In conclusion, the VP7, VP4, NSP4 and NSP5 genes of LLZ212 share high levels of sequence identity with human GARV, while VP2, VP6, NSP2 and NSP3 cluster with porcine GARV.

Recently,as the exposure of the incident of‘octuplet’in Guangdong province,China's underground surrogate market has once again surfaced and led to a wide range of discussion.In this paper,the connotation and characteristics of surrogacy were analyzed and related laws and regulations of surrogacy in foreign countries were discussed.The main types of surrogacy-related legislation and regulations abroad are autonomy of private law,governmental regulation and complete prohibition.This paper carried out thorough legal analysis on whether to prohibit strictly or establish an authoritative legal system in view of the existing and ineffectively prohibited underground surrogate market in our country.
