Objective Among the various components of metabolic syndrome(MS),this investigation attempt to find the most important one.Furthermore,to verify the feasibility of using waist circumference(WC)for assessing the diagnostic criteria for MS proposed by the CDS in 2004.Methods Among 163 cases recruited,80 patients met the criteria of MS and 83 cases were diagnosed as non-metabolic syndrome group(non-MS).Age,WC,body mass index(BMI),fasting plasma glucose,lipid profile,blood pressure were compared between patients of MS and non-MS.Logistic regression analysis and area under curve(AUC)of receiver-operating characteristic(ROC)were used to study the predictive value of WC.Results Patients with CDS-defined MS showed a significantly higher age,WC,SBP,DBP,fasting plasma glucose,triglycerides(TG),1/HDL-C when compared with non-MS group.After adjusting for age,the family history of diabetes and hypertension,smoke,multiple logistic regression analysis revealed WC was the most important predictive factor for MS group.ROC analysis showed that the AUC of WC was 0.92 in the males,the cut-off value is 89.5 cm,the sensitivity was 0.84,the specificity was 0.93;the AUC of WC was 0.93 in the females,the sensitivity was 0.97,the specificity was 0.81 when cut-off value is 80.8 cm.This investigation has shown that smoking was also a component of MS.The relative risk of MS in current smokers and sustained smoker was higher than that of abstinence(6.88 vs 1.00 and 3.96 vs 1.00).Conclusion Central obesity is the riskest indicator for the diagnostic criteria for MS proposed by the CDS,WC is verified to be the accuracy and satisfactory predictive indicators for MS.Smoking may be a novel component of MS.

BACKGROUND:With the development and improvement of liver transplantation technology, patients waiting for or undergoing liver transplantation have continued to increase in number. Due to their fears and concerns about post-transplantation rehabilitation, patients are under physical and mental stress, most of whom are shown to have a variety of mental disorders that affect rehabilitation. At present, mental problems of liver transplant patients are more concentrated in post-transplantation research, while patients waiting for liver transplantation do not get enough mental assessment and intervention.
OBJECTIVE:To investigate the suitable mode of cognitive-behavioral therapy for liver transplant recipients waiting for donor liver and to evaluate the effect to improve patient’s physical and mental state.
METHODS:Twelve liver transplant patients who underwent pre-transplantation assessment were randomly divided into experimental group and control group, each group with six cases. The control group received conventional treatment. The experimental group received cognitive-behavioral therapy in addition to conventional treatment. Self-rating anxiety scale (SAS) and vital signs were measured in the two groups on admission, 1 week and 3 weeks after admission.
RESULTS AND CONCLUSION:The SAS score of the experimental group was lower than that of the control group at 1 and 3 weeks after admission, and SAS score decreased as the intervention extended. The systolic blood pressure of the experimental group was lower than that of the control group at 3 weeks after admission, but there was no significant difference in diastolic blood pressure between two groups. The heart rate of the experimental group was lower than that of the control group at 1 and 3 weeks after admission. The respiratory rate of the experimental group was lower than that of the control group at 3 weeks after admission. Cognitive-behavioral therapy can reduce the level of anxiety and keep vital signs stable with good feasibility and effectiveness in patients waiting for liver transplantation.

The transcriptional factor Oct-4 and Survivin are the key regulatory factors in cancer cell proliferation and mitosis. A dual cancer-specific shRNA adenovirus vector, Ad5-Dual-shRNA, targeting Oct-4 and Survivin genes was constructed by molecular cloning and recombination. After cells were infected with virus, hepatocellular carcinoma cell line EHBH-H1 was used for detecting the expression of Oct-4 and Survivin proteins by Western blotting. The viral cytotoxic effect on cancer cells was detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) reduction assay in vitro, and the inhibition effect on tumor xenografts was observed in nude mice. The results showed that the expression of Oct-4 and Survivin in cancer cell line EHBH-H1 could be silenced markedly by Ad5-Dual-shRNA. In MTT and animal experiments, Ad5-Dual-shRNA also represented much stronger anti-tumor effect on tumor growth than Ad5-Surv-shRNA and Ad5-Oct4-shRNA. From this research we can draw a conclusion that the cancer-specific adenovirus vector expressing dual-shRNA targeting Oct-4 and Survivin genes may provide us a more effective, specific and convenient gene therapy method.
