This paper gives the brief account of the researches in the effection of the side- cuts in perineum carried out in two angles (45°and 25~30°) during the helps in child birth between two groups of eutosia on the similar condition:fetal weight the contradict of womb perineum tissue e. g.. The results show that amnong 116 parturients with side- cut in 45( contrated group), the rate of tearing is 62.06%; on the contrary, among 110 parturients with side - cut in 25 ~ 30°( improved group), the rate of tearing is 35.45 %. According to statistics analysis, the rate of tearing in two groups has a marked difference (P<0.01). It directly shows the parturients in improved group have the advantages:shortening the sewing- up time lessening needling numbers reliving of the after - pains making the parturients get out bed some time later and sulkle the new- born babies in sitting way,reducing the nursing,shortening the time of infection.

OBJECTIVETo explore the molecule mechanism of Salidroside inducing directional differentiation of mouse mesenchymal stem cells (MSCs) into neuronal cells.
METHODSThe mouse multipotent mesenchymal precursor cell line (D1) was taken as the objective. Cultured MSCs were divided into the negative control group (complete culture solution), the positive control group (containing 1 mmol/L β-mercaptoethanol), the Salidroside induced group (20 mg/L Salidroside), and the blocked group (20 ng/ ml DKK1, a special inhibitor of Wnt/β-catenin signal pathway). All cells were inoculated in a 6-well plate (1 x 10(4) cells/cm2) and grouped for 24 h. The expression of p-catenin was detected by fluorescence Immunochemistry in the negative control group, the positive control group, and the Salidroside induced group. The expression of neuron-specific enolase (NSE), beta 3 class III tubulin (β-tubulin III), nuclear receptor related factor 1 (Nurr1), glial fibrillary acidic protein (GFAP) mRNA, Wnt3a, β-catenin, low-density lipoprotein receptor-related protein6 (LRP6), Axin mRNA were detected using reverse transcrip- tion PCR (RT-PCR). The expression of β-catenin and NSE protein were analyzed by Western blot in the negative control group, the positive control group, and the Salidroside induced group. Ca2+ chelating agents (EGTA), L-type Ca2+ channel blocker (Nifedpine), and IP3Ks special inhibitor (LY294002) were used to block Ca2+ signal pathway respectively. The expression of Wnt3a, LRP-6, Axin, glycogen syn- thase kinase (GSK-3), and β-catenin mRNA were detected by RT-PCR. The β-catenin protein expression was analyzed using Western blot.
RESULTSCompared with the positive control group, β-catenin protein was strong positively expressed; the expression of Wnt3a, β-catenin, LRP6, Axin, NSE, β-tubulin III, Nurr1 mRNA, and NSE protein were obviously up-regulated in the Salidroside induced group (P < 0.01). Compared with the positive control group and the Salidroside induced group, β-catenin, NSE, Nurr1, and β-tubulin III mRNA expression decreased; β-catenin and NSE protein expression were also down-regulated in the blocked group (P < 0.01). Compared with the Salidroside induced group, the expression of Wnt3a, LRP-6, β-catenin, and Axin mRNA were down-regulated in the Ca2+ signal blocked group and the salidroside induced group (P < 0.01, P < 0.05).
CONCLUSIONSalidroside affected directional differentia- tion of MSCs into neuronal cells through Wnt/β-catenin and Ca2+ signal pathway.

Objective:To clone the RC-RNase gene and prepare its recombinant prokaryotic construct, and then to express RC-RNase protein using Escherichia coli system. Methods: RC-RNase cDNA was obtained by RT-PCR from liver of Rana catesbeiana, and cloned into pUCm-T plasmid for nucleotide sequencing. Its expression construct was prepared using the 6?His vector pRSET-A, and induced to express by IPTG in Escherichia coli BL21(DE3). Western blotting identified the expression product. Results: A 380 bp long cDNA was obtained from liver of Rana catesbeiana, restriction sites and sequence being consistent to those reported for RC-RNase. After introducing the gene into Escherichia coli and through the induction by IPTG, it was observed a new peptide at the expected position (Mr 16000) on SDS-PAGE gel. This product was proved to be the target protein via Western blotting. It existed in a form of inclusion body and its efficiency reached 12.5% of total bacterial proteins. Conclusion: RC-RNase gene was cloned and expressed in Escherichia coli. The protein could be used for characterizing the biological activities and function of RC-RNase.

Background and purpose: Magnetic resonance spectroscopy is currently the only non-invasive magnetic resonance imaging technique which can detect metabolite composition of live organ and tissue and also conduct semi-quantitative or quantitative analysis. We analyzed the characteristics of metabolic changes among normal liver, cirrhosis regenerative nodule and liver cancer on the background of cirrhosis by voxel proton MR spectroscopy at 1.5 Tesla. Methods: 20 healthy volunteers (control group), 25 cirrhosis (cirrhosis group) and 23 hepatocellular carcinoma after cirrhosis (HCC group) patients were our candidates. The characteristics of spectra of ~1H-MRS were observed. The height and ratio of choline complex (Cbo) and lipid methylene (Lip2) were recorded and the results were compared among the groups. Results: The success rate of ~1H-MRS was about 88.2% (60/68). There were statistically significant differences among the heights of Lip2 peak of the three groups, and also between that of the control group and the group of liver cancer. But there were no significant differences between that of control group and cirrhosis group, cirrhosis group and liver cancer group. The comparison of the height of Cho peak and the ratio of Cho/Lip2 showed statistically significances both among the three groups and between each other. Conclusion: The metabolic changes of the liver could be shown non-invasively by ~1H-MRS, which could be useful for differential diagnosis or diagnosis of cirrhosis regenerative nodule and HCC.

Plasma viral RNA load is widely accepted as the most relevant parameter to assess the status and progression of Simian immunodeficiency virus (SIV) infections. To accurately measure RNA levels of the virus, a one-step fluorescent quantitative assay was established based on the SYBR green Real-time reverse transcription-polymerase chain reaction (RT-PCR). The lower detection limit of the assay was 10 copies per reaction for the virus. This method was successfully applied to quantify SIVmac251 and SIVmac239 viruses produced in CEM×174 cells. Additionally, the performance of the SYBR green RT-PCR was assessed in a SIVmac251 infected rhesus macaque. The result demonstrated that the method could detect as little as 215 copies per milliliter of plasma and the dynamic pattern of viral load was highly consistent with previous results. With regard to convenience, sensitivity and accuracy our assay represents a realistic alternative to both branched-chain DNA (b-DNA) assays or real-time PCR assays based on TaqMan probes.

Objective To observe the effects of chemo-endocrine therapy on gastric carcinoma (GC). Methods Cancerous tissues from 95 patients with primary GC were examined for the presence of estrogen receptor (ER) and progesterone receptor (PgR). Afterwards, 64 GC patients with recurrent or metastatic conditions were randomly divided into two groups: chemotherapy group and chemo-endocrine therapy group. Results A total of 34.38% ER positive and 16.30% PgR positive rates were found. For ER positive patients, the use of tamoxifen-EAP regimens was more effective than that of EAP alone (P
