Objective To investigate the effect of diazepam injection on the degree of cervical dilatation, delivery outcome and negative emotion in the first stage of labor. Methods Retrospective study of 120 cases of maternal birth in our hospital as a study sample. Diazepam was used in the first stage of labor, and 60 cases of women with worse cervical dilatation and negative mood were selected as observation group, the other selected not to use any drug-assisted childbirth, only to take the basis of comfort and other interventions, the clinical symptoms and observation group were similar to 60 cases of maternal were classified as control group. The effects of the two groups intervention on maternal mood, delivery outcome and cervical dilatation were compared. Results The self-rating anxiety scale (SAS) and self-rating depression scale (SDS) scores of the observation group were significantly lower than those of the control group at 1h, 12h and 24h after treatment, the difference was statistically significant (P<0.05). Observation group Bishop cervix related degree of cervical dilatation, cervical soft and hard, cervix position, cervical canal disappearance and fetal exposure were significantly higher than those of the control group, the difference was statistically significant (P<0.05). The rate of spontaneous delivery in the observation group (83.33%) was significantly higher than that the control group (56.67%), the difference was statistically significant (P<0.05). There were no statistical differences in the rate of adverse childbirth in the observation group (11.67%) and the control group (10.00%). Conclusion The use of diazepam injection in the first stage of labor can effectively improve the overall maturity of maternal cervix, relieve maternal depression, anxiety and other negative psychological, and drug safety is high, and there was no significant adverse effect on the outcome of their childbirth.

Enantioselective hydrolysis of 2-carboxyethyl-3-cyano-5-methylhexanoic acid (CNDE) is the key step in chemoenzymatic synthesis of pregabalin. We purified an intracellular carboxyl esterase from Morganella morganii ZJB-09203, which exhibited high enantioselectivity and activity towards CNDE. The carboxyl esterase was purified to electrophoretic homogeneity by ammonium sulfate fraction precipitation, Phenyl Sepharose 6 FF hydrophobic interaction chromatography, anion exchange with DEAE Sephadex A-50 and Bio-Scale CHT column. The purified enzyme was a monomer with molecular mass of 68 kDa determined by SDS-PAGE and gel chromatography. Substrate specificity of the enzyme towards p-nitrophenyl esters suggested that the purified enzyme was an esterase. The optimal reaction pH for CNDE hydrolysis was 9.0, and optimal temperature was 45 degrees C. The esterase was stable between pH 7.0 and 9.0, and at 40 degrees C. The enzyme activity was enhanced by Ca2+, Cu2+ and Mn2+, whereas strongly inhibited by Co2+, Fe3+, Ni2+ and EDTA. Meanwhile, we investigated the kinetic parameters of the esterase towards p-nitrophenyl esters and effect of CNDE concentration on conversion. The present study reported the esterase capable of stereospecific hydrolysis of CNDE for the first time. Our research will provide foundations for industrial production of Pregabalin using the new biocatalyst.

Objective To investigate the expression of MMP-2 and MMP-7 and their elinieopathologieal significance in eoloreetal carcinomas. Methods The expression of MMP-2 mRNA, MMP-7 mRNA and MMP-2, MMP-7 in 42 samples of eoloreetal carcinomas and its adjacent normal eoloreetal mueosa were examined using fluo-rescence quantitative RT-PCR (FQ-RT-PCR) and immunohistoehemistry. The relationship of their expression with some elinieopathologieal characteristics was analyzed. Results MMP-2 mRNA, MMP-7 mRNA and MMP-2, MMP-7 were significantly over-expressed in eoloreetal carcinomas compared with its adjacent normal eoloreetal mueosa( P < 0.05 ) , and they were positively associated with bowel wall invasion, the regional lymph node metastasis and Dukes stage. The expression of MMP-2 mRNA and MMP-7 mRNA was positively correlated with MMP-2 and MMP-7 in eoloreetal eareinornas. Conclusions MMP-2 and MMP-7 may play a key role in eoloreetal carcinogenesis,tumor in-vasion and metastasis. Examination of combined MMP-2 and MMP-7 expression may have an important significance to judge the malignant degree and biological behavior of human eoloreetal carcinoma and for evaluating the progno-sis.

Objective Since the discovery of multiple bioactivities of agarobiose oligomers, the establishment of quantitative analysis of agarobiose oligomers obtained under different hydrolysis modes would be of much importance. Methods Agarobiose oligomers ranged from biose, tetraose, hexaose, octaose, to decaose were isolated and purified by gel chromatography on Sephadex column. The agarobiose oligomers were separated in RP-HPLC after introducing ?-naphthylamine into compounds. Results Each oligomer could be quantified with good linearity and the lowest detection limit reached 0.1～2 ?g?mL -1. The chromatograms profiles under different hydrolysis modes(HCl, citric acid, solid acid, and hydroxyl radical degradation)showed that the content of agarobiose could reach more than 57.8 % using solid acid hydrolysis with best yield of 33.2 % . While HCl could degrade agar into a series of agaro-oligosaccharides from biose to decaose. The yield of oligosaccharides was low if hydrated by citric acid. The method of Fenton degradation could increase the speed of hydrolysis, but the products were more complex. Conclusion The method established here could be useful for analysis of hydrolysates of oligomers under different hydrolysis modes.
