Background and purpose: E-cadherin (EC) is a type of glycoprotein, which could maintain epithelial polarity and cell-cell junction. It is thought to be associated with the development and progression of hepatocellular carcinoma (HCC). The study aimed to detect expression of uniting detection sEC and AFP before and after operation in patients, and to monitor recurrence of postoperative. Methods:The levels of sEC and AFP in 105 HCC patients were tested by enzyme linked immunosorbent assay (ELISA) and radioimmunoassay (RIA) before and after operation as well as in 70 healthy controls. Theirs correlation with clinical and pathological factors was analyzed. We analyzed the level of plasma sEC and AFP of 47 patients who had been suffered from the hepatocellular carcinoma operation and relapse. Results: The levels of sEC and AFP in HCC patients before operation were significantly higher than in controls, which declined significantly one week after operation. The sEC level before operation showed significant correlation with TNM staging (P<0.01), edmondson grade, the carcerous thrombi within the portal vein and the capsule of carcinoma (P<0.05), but not with age of patients or the tumor size (P>0.05). While AFP only correlation with TNM staging (P<0.05), not with others factors (P>0.05). When the recurrence was confirmed, the level of sEC was much higher significantly than the level postoperation (P<0.01). Conclusion:The levels of sEC in HCC patients before operation are closely related with prognosis and recurrence of HCC. The unites detection of sEC+AFP may be a predictive factor for recurrence of postoperation.

Objective To investigate whether nimodipine could reduce complications after microvascular decompression in patients with hemifacial spasm. Methods 220 patients with hemifacial spasm , admitted into our hospital from May 2011 to Oct. 2013 , were all treated by microvascular decompression. They were divided randomly into two groups. Patients in the treatment group were treated with nimotop 50 mg/d after the operation for the first 3 days, then was orally taken 30 mg/d for a week. Patients in the control group were treated with the same after the operation without nimodipine. The postoperative complications including hearing deficit and peripheral facial paralysis were closely observed within three months after operation. Results The total effective rate was 100% in both groups. The incidence rate of peripheral facial paralysis and hearing deficit in treatment group was significant lower than that of the control group (P < 0.05). Conclusion Nimodipine has significant effect on reducing the incidence rate of peripheral facial paralysis and hearing deficit after microvascular decompression in patients with hemifacial spasm.

In order to investigate the effect of malic enzyme on anaerobic mixed acid fermentation,the gene encoding NAD+-dependent malic enzyme was amplified from E.coli DH5? genome by using PCR and cloned into vector pTrc99a to give an expression vector pTrc99a-sfcA.Malic enzyme was overproduced by E.coli FMJ39(ldh,pfl)harboring pTrc99a-sfcA under the condition of IPTG induction.The results of anaerobic fermentation indicated overexpression of malic enzyme would have influence on the pathway of formate,acetate and succinate of FMJ39.The concentration of formate and acetate was 17.58% and 15.27% higher than FMJ39,the succinate concentration was reduced by 26.87%.There was no obvious citrate concentration change.The experimental results also indicated that high concentration of L-Thr and L-Ser would induce the Tdc operon to convert pyruvate into formate and acetate even when pfl gene encoding the pyruvate formate lyase was inactivated.

To increase the biotransfomation efficiency from the orotic acid to the uridine 5'-monophosphate(UMP),URA5 gene encoding orotate phosphoribosytransferase was amplified from Saccharomyces cerevisiae BY4742 by PCR,then it was inserted into the expression vector pYX212(contained orotidine monophosphate decarboxylase gene URA3)and the pYX212-URA5 was transformed into Saccharomyces cerevisiae BJX12 by electroporation.The recombinant strain was elementarily used to convert orotic acid to UMP.The results showed that pYX212-URA5/BJX12 could accumulate 7mmol/L UMP from 32mmol/L orotic acid in 26h,significantly higher than both control groups pYX212/BJX12(2.7mmol/L) and BJX12(2.4 mmol/L).

AIM To establish a high performance liquid chromatographic method (HPLC) to determine the concentration of valsartan in human plasma. METHODS Separation was achieved on the lichrospher C 18 column. The mobile phaseconsisted of pH 3 1 phosphate buffer acetonitrile (53∶47, V/V) was used at a flow rate of 1 0 ml?min -1 . The fluorimetric excitation and emission wavelengths were set at 265 nm and 378 nm, respectively. The plasma samples were acidified with HCl, extracted with ethyl acetate. Separate the organic phase, remove the solvent and then residue was dissolved in mobile phase. RESULTS The retention time of valsartan was 12 5 min. The calibration curves were linear in the range of 5 9～ 2 360 ?g?L -1 . The precision values (RSD) of intra day and inter day were determined to be 2 83%～7 07% and 1 57%～8 41% respectively. The absolute recovery rate were 80 30%?5 13%. The method was applied to determine the peak and valley concentrations in plasma of the hypertensive treated with 80mg valsartan per day. CONCLUSION The assay was sensitive and simple. It is suitable for the study of the pharmacokinetics of valsartan.
