Objective To observe the inhibitory effect of andrographolide (AD) on the migration and invasion of human cervical cancer cells,and investigate the molecular mechanisms underlying the inhibitory effect of AD.Methods Human cervical cancer cell lines HeLa cells were cultured in vitro.After induced by 100 nmol/L of phorbol-12-myristate-13-acetate(PMA) for 24 h,different concentration of AD was co-incubated for another 24 h.Cell viability was detected by methyl thiazolyl tetrazoliym (MTT) assay.Chamber invasion assay was used to observe the migration and invasion,respectively.Expression of matrix metalloproteinase-9 (MMP-9) and translocation of nuclear factor kappa B (NF-κB) p65 subunit were detected by Western blot.Results The concentration (0 ~ 10 μmol/L) of AD exhibited a non-cytotoxic effect on HeLa cells.10 μmol/L of AD decreased PMA-induced migration by 49% and invasion by 52%.Western blot showed that AD suppressed PMA-induced MMP-9 protein expression in a dose-dependent manner.Treatment of AD could decrease the translation of p65 in HeLa cells.Conclusions AD inhibits MMP-9 expression mediated by NF-κB,which lead to the suppression of migration and invasion of cervical cancer cells.

Objective: To investigate effect of exogenous wild-type p53 gene on the cell growth and tumorigenicity of human gallbladder cancer cell lines. Methods: After identification of the genetic status of p53 gene of GBC-SD cell lines with the immunocytochemistry staining and the direct sequencing technique of PCR products, eukaryotic expressing plasmid pCMV-p53 was introduced by lipofectamine-mediated into GBC-SD cell lines. Growing transfected cells were selected by G418. The presence and expression of exogenous p53 gene was detected by PCR, RT-PCR and Western blot. The cellular proliferating ability was assessed using the cell growth curve and cloning assay. The xenograft in nude mice was performed to examine the effect of tumorigenicity. Results: P53 protein overexpression was showed in GBC-SD cell lines. A transversion of TAC→AAC at codon 126 of exon 5 was confirmed. PCR, RT-PCR and Western blot showed exogenous p53 gene had successfully transfected into GBC-SD cells and obtained high expression. The growth and proliferation of the cells were greatly decreased, and the tumorigenicity was significantly inhibited after transfection wtp53. Conclusion: The expression of exogenous wild-type p53 gene could effectively inhibit the growth of gallbladder cancer GBC-SD cells in vitro and in vivo.

The pharmacoclynamics of Kuntaian was studied. The results showed that it exerts an inhibiting effect on normal uterine smooth muscle in a dosedependent manner. It can counteract the violent uterine contraction induced by pituitrin, promote the growth of uterus of young mice, dilate the capilaries and accelerate blood circulation. It also exerts analgesic antiphlogistic antioneotie effects, suggesting that this drug may be applicable to the treatment of dysmanorrhea, irregular menstruation and pelvic infection.

Objective To explore an effective treatment for inflammatory hilar bile duct stricture. Methods The clinical data with patients of intra hepatic cholelithiasis complicated with hilar bile duct stricture that received plastic repair of hilar bile duct stricture(PHBDS) with pedicled cholecystic graft or Roux en Y cholangio jejunostomy (RYCJ) in our hospital during recent 10 years were retrospectively analyzed. The peri operative conditions, postoperative morbidity of cholangitis and recurrence of hepaticolithiasis were observed . Results The peri operative morbidity of biliary fistula and inflammatory ileus were not significantly different between the two groups. The postoperative morbidity rate of cholangitis was 5.66% and 21.88%,(P=0.010) and recurrence rate of hepaticolithiasis was 3.77% and 16.67%,(P=0.021) in PHBDS group and RYCJ group respectively . Conclusions PHBDS is an easy and safe operation. RHBDS can preserve the physiologic function of Oddi′s spincter, so the reflux of intestinal contents to bile duct is avoided , and the results are better than the RVCJ.

Objective To investigate the effects of prophylactic antiviral therapy for HBV DNA negative HBV-relat-ed hepatocellular carcinoma (HCC) patients undergoing hepatic arterial chemoembolization (TACE). Methods Fifty-four consecutive patients with HBV-related HCC and received TACE were enrolled in this study. Thirty patients received pre-emptive antiviral drugs before TACE were defined as the treatment group. Twenty-four patients, who did not use antiviral drugs until HBV reactivation after TACE, were included in control group. The incidence of HBV reactivation, duration from HBV DNA positive point to the last time of TACE, the occurrence of abnormal alanine aminotransferase (ALT) caused by HBV reactivation, the peak of aspartate aminotransferase (AST) and the number of liver failure caused by HBV reactivation were observed after TACE in two groups. Results The incidence of HBV reactivation, the occurrence of abnormal ALT, the occurrence of abnormal ALT caused by HBV reactivation, the peak ALT and peak AST were significantly lower in treatment group than those of control group (P < 0.05). No liver failure caused by HBV reactivation was found in treatment group. There were four patients with liver failure caused by HBV reactivation in control group. There was no significant difference in cumulative survival rate between two groups (P=0.071). Conclusion It is suggested that preemptive antiviral therapy can prevent the reactivation of hepatitis B virus, prevent the deterioration of liver function,and decrease the occurrence of liv-er failure caused by HBV reactivation in patients receiving TACE.

Objective: To investigate the mechanism of vascular endothelial growth factor ( VEGF)165 and hepatocyte growth factor (HGF) improving cardiomyocyte proliferation in experimental porcine after myocardial infarction (MI).
Methods: The MI model was established by left anterior descending artery ligation in 15 male pigs and the animals were divided into 3 groups, n=5 in each group. Control group, the pigs received normal saline injection at the infarct and peri-infarct zones. VEGF group, the pigs received (1×1010 ) pfu of viral titers of Ad-VEGF injection. HGF group, the pigs received (1×1010 ) pfu of viral titers of Ad-HGF injection. The myocardial perfusion and cardiac function were examined by SPECT, the protein expressions of VEGF165 and HGF were measured by Western blot analysis, cardiomyocyte proliferation was analyzed by immunolfuorescence and immunoprecipitation method.
Results: ① Compared with Control group, the expressions of VEGF165 and HGF were higher at the infarct and peri-infarct zones in both treatment groups; ② Both treatment groups had better cardiac function and myocardial perfusion; ③ Both treatment groups had improved cardiomyocyte proliferation at the infarct and peri-infarct zones.④VEGF165 promoted cardiomyocyte proliferation via p27 pathway;⑤HGF promoted cardiomyocyte proliferation via p21 and p27 pathways.
Conclusion: VEGF165 and HGF could improve myocardial perfusion and function in experimental porcine after MI, VEGF165 and HGF promote cardiomyocyte proliferation via different pathways.
