Objective To study the effect of vitamin K3 (VitK3) on the apoptosis of human hepatocellular carcinoma cell line of HEPG2 and its relationship with Caspase-3 and Bcl-2 gene. Method With the treatment of VitK3, time and dosage effect was detected by MTT colorimetry. Appoptosis was observed by morphology, flow cytometry and DNA agarose gelelectrophoresis.Caspase-3 and Bcl-2 mRNA expression was assessed by RT-PCR. ResultVitK3 significantly inhibits HEPG2 cell proliferation and induce apoptosis.Caspase-3 mRNA expression was upregulated. ConclusionVitK3 induces HEPG2 cell apoptosis by way of Caspase-3 gene expression.

Transforming growth factor-β is an important cytokine with various bioactivities, including embryonic development, wound healing, chemotaxis and cell cycle regulation. Epithelial-mesenchymal transition (EMT) is the main pathway of tumor cell to obtain the ability of invasion and metastasis. The TGF-β is the key factor known to induce EMT in cancer cells and plays an important role in the process. In recent years, some progress has been obtained. Some TGF-β inhibitors have approved in the market or in clinical trials. TGF-β inhibitors can play an important role on the treatment of tumors, glaucoma, liver and kidney fibrosis disease and scar repair. Novel TGF-β inhibitors reported in recent years were reviewed in this article.

Objective To understand the gene carrying rate ,gene mutation types and distribution characteristics of thalassemia in the northeast area of Chongqing .Methods 28 633 specimens collected from the patients and individuals with physical examina‐tion in our hospital from January to December 2013 were performed the RBC parameters detection and hemoglobin electrophoresis screening .The specimens with phenotype positive were definitely verified the thalassemia type by using Gap‐PCR and reverse dot blot(RDB) .Results Among 28 633 specimens ,1 358 specimens were finally diagnosed as thalassemia with the thalassemia carrying rate of 4 .74% ,including 589 cases(2 .06% ) of α‐thalassemia and 741 cases (2 .59% ) of β‐thalassemia cases .Among the α‐thalasse‐mia genotypes ,‐αα/‐‐SEA genotype(1 .38% ) was most common ,the next was ‐αα/‐α3 .7 genotype (0 .37% ) and αα/‐α4 .2 genotype (0 .20% ) .Among the β‐thalassemia genotypes ,CD41‐42 genotype (1 .27% ) had the highest constituent ratio ,followed by IVS‐2‐654 genotype(1 .27% ) and CD17 genotype(0 .30% ) .28 cases were found to be the double heterozygote with α‐thalassemia and β‐thalassemia .Conclusion The northeast area of Chongqing is a region with the high incidence rate of thalassemia and complicated heredity .Therefore this research provides the reference information for the prevention of thalassemia ,genetic counseling and prena‐tal diagnosis .

It remains controversial whether tumor necrosis factor (TNF)-α antagonism is effective for asthma. This meta-analysis was performed to evaluate efficacy of TNF-α antagonism in treatment of patients with asthma. MEDLINE, EMBASE, LILACS, and CINAHL databases were searched for English-language studies published through January 3, 2010. Randomized-controlled trials comparing TNF-α antagonism with control therapy were selected. For each report, data were extracted in relation to the outcomes analyzed: asthma exacerbation, asthma quality of life questionnaire scores, and forced expiratory volume in 1 second. Four assessable trials were identified including 641 patients with asthma. TNF-α antagonism therapy was superior to control therapy in preventing exacerbations in asthmatics [pooled odds ratio 0.52 (95% confidence interval 0.29-0.88), P=0.02]; however, there was a nonsignificant reduction in asthma quality of life questionnaire scores [0.23 (0 to 0.47), P=0.05], forced expiratory volume in 1 second [0.03, (-0.14 to 0.10), P=0.74] when analyzed using standardized mean differences. TNF-α antagonism was superior to control chemotherapy in terms of asthma exacerbation, but not asthma quality of life questionnaire scores or forced expiratory volume in 1 second.

Objective To analyze long-term efficacy after surgical treatment of primary liver cancer with fluorouracil plus oxaliplatin plus gemcitabine joint implementation to prevent the overall intervention effect of hepatic arterial infusion chemotherapy and radical resection of hepatocellular carcinoma following ascension.Methods60 cases of primary hepatocellular carcinoma were randomly divided into study group and control group according to the random number method in our hospital from February 2011 to November2013, 30 cases in each group.All patients underwent radical resection of liver cancer and liver (partial) resection.In the control group, the patients were treated with anti viral or immune enhancement after surgery, and the follow-up treatment was not carried out.In study group were given anti-virus or immune intensive treatment and at the end of surgery 3 and 7 weeks after the implementation of a prophylactic transcatheter arterial infusion chemotherapy and selecting drug 5-FU, oxaliplatin and gemcitabine.During 3 years of follow-up, the incidence of adverse reactions in the 3 groups was statistically analyzed, and the recurrence free survival rate, disease-free survival rate and overall survival rate of the two groups were statistically analyzed.ResultsAll patients completed the follow-up, there was no loss of follow-up cases.In adverse reactions, the study group patients were successfully tolerated hepatic artery infusion chemotherapy, no obvious adverse reactions or drug toxicity, more no interruption of chemotherapy cases.The recurrence free survival rate, disease-free survival rate and overall survival rate of the study group were 83.33%, 70.00%, 86.67%, respectively, which were significantly higher than those in the control group (60.00%, 43.33%, 63.33%) (P<0.05).ConclusionPrimary hepatocellular carcinoma should be treated with prophylactic hepatic arterial infusion chemotherapy in time after radical operation, which can greatly improve the survival rate of patients and ensure long-term curative effect.

OBJECTIVE To analyze the sequence of IMP-4 metallo-?-lactamases(MBLs) encoding gene from clinical isolates of multiple-drug-resistant Klebsiella oxytoca strains and attempt to know the integrons composing the drug resistance gene box.METHODS The antibiotic sensitivity test of multi-resistant K.oxytoca strains was done according to Kirby-Bauer method of CLSI 2005,and the double disk synergy test and Etest were for detecting their MBLs.The Class 1 integrons were detected by PCR.The purified amplicons of Class l integrons were sequenced.The type and order of gene cassettes in integrons were analyzed by searching GenBank.RESULTS The K.oxytoca was resistant to carbapenems,the third-generation cephalosporins,cefoxitin,quinolones,cefoperazone/sulbactam,sulfamethoxazole/trimethoprim,amoxicillin/clavulanate,ticacillin/clavulanate,piperacillin,cefepime,rifampicin and piperacillin/tazobatam,only susceptible to amikacin and polymyxin B.The IMP-4 metallo-?-lactamases,aadA1,AmpC,CTX-M-14,qacE△1-sull and intI1 were positive.CONCLUSIONS Integrons are important molecular mechanism in the development of multidrug resistance.There are resistance gene boxes in them.

Objective To evaluate the efficacy of heat sensitive moxibustion plus herbal hot compress for primary dysmenorrhea. Methods Ninety patients with primary dysmenorrhea were randomly allocated to a treatment and a control group, with 45 patients in each group. The treatment group was treated with heat sensitive moxibustion plus herbal hot compress, and the control group received ibuprofen (slow-release capsule) for three menstrual cycles. Results At the end of the first menstrual cycle, the total instant effective rate in the treatment group was significantly higher than that in the control group (95.6%vs. 82.2%;χ2=4.050, P<0.05);at the end of the third menstrual cycle, healing rate (66.7% vs. 35.6%; χ2=8.720, P<0.05), total effective rate (97.8%vs. 80.0%;χ2=7.200, P<0.05) in the treatment group were significantly higher than those in the control group;at 6 months follow-up, the relapse rate in the treatment group were significantly lower than that in the control group (6.7% vs. 43.8%; χ2=4.050, P<0.05). Conclusion Heat sensitive moxibustion plus herbal hot compress is a effective approach for primary dysmenorrhea.
