The field of integrative medicine (IM) has grown tremendously in the United States over last two decades, in terms of clinical practice, research, and education. Its growing popularity among patients has led to increased need for physicians with appropriate counseling skills and a knowledge base of the efficacy and safety of complementary and alternative medicine (CAM) therapies. Family medicine is the first specialty as a whole to embrace IM, which encounters similar ailing conditions and emphasizes similar core values-person centered, evidence based, proactive, and continuous in nature. As integrative family medicine emerges, family medicine educators have developed suggested curriculum guidelines and approved measurable competencies to implement the best of evidence-based CAM and principles of IM. There are currently over 40 family medicine residencies that officially advertise CAM/IM in their programs. Meanwhile, IM centers have also been developing their own primary care programs based on their unique characteristics. This physician-led IM workforce is similar to that of China's IM in the early 1960s. As the Chinese government embarks on repeating its efforts to educate more Western medicine trained physicians in Chinese medicine in primary care training programs, the process and insights related to implementation of their practice in the United States would provide useful food for thought.

Objective To evaluate the efficacy of entecavir treatment on hepatitis B patients with acute-on-chronic liver failure. Methods Eighty-four hepatitis B patients with acute-on-chronic liver failure were treated with entecavir 0.5 mg daily and Other routine drugs. Another 99 hepatitis B patients with acute-on-chronic liver failure were treated with only routine drugs as control. The survival, liver functions, hepatitis B virus (HBV) DNA level, prothrombin time (PT) were observed. The survival rates of patients with early, middle or late stage of liver failure were analyzed. The comparison of rates were done using chi-square test. The numeration data were compared by t test. The survival rates were compared using Kaplan-Meier method. Results Among patients with early stage of acute-on-chronic liver failure, the survival rate in treatment group was 63.3% (31/49), which was significantly higher than that in control group (39.7%, 23/58) (χ2=5.923, P=0.015). Among patients with middle stage of acute-on-chronic liver failure, the surviral rate in treatment group was 63.0% (17/27), which was significantly higher than that in control group (35.1%, 13/37) (χ2=4.854, P=0.028). Among patients with late stage of acute-on-chronic liver failure, four out of eight cases survived in treatment group, while one out of four cases survived in control group. In patients with serum total hilirubin (TBil) level > 342 μmol/L, the survival rate was 56.0% in treatment group, which was significantly higher than that in control group (26.8%) (χ2=9.351,P=0.002). At week 4 of the treatment, the HBV DNA reduction in treatment group was 3. 95 lg copy/mL, which was higher than that in control group (1.78 lg copy/mL) (t=5.847, P=0.001). Conclusions Entecavir treatment could improve the survival rate of hepatitis B patients with early or middle stage of acute-on-chronic liver failure. And the further study with larger population is needed in patients with late stage of liver failure. In addition, entecavir therapy could also improve the survival rate of patients with TBil >342 μmol/L.

Objective: To construct the eukaryotic expression vector pSurp-EGFP regulated by the survivin gene promoter and to detect the specific expression of the promoter in human laryngeal cancer Hep-2 cells by green fluorescent protein assay.Methods: Thesurvivin gene promoter was generated by polymerase chain reaction(PCR) and the CMV promoter of the pShuttle vector replaced by the survivin gene promoter to generate the plasmid pSurp.The three plasmids pShuttle,pSurp and pEGFP-C1 were respectively double-enzyme digested so as to produce the plasmids pCMV-EGFP and pSurp-EGFP carrying the CMV or survivin promoter.The purified pCMV-EGFP and pSurp-EGFP were transfected into Hep-2 cell and vascular endothelial cell ECV304 using liposome transfection reagent and the expressions of EGFP detected by the fluorescent microscope.Results: Thesurvivin gene promoter was successfully cloned by PCR,and thesurvivin gene promoter-regulated pSurp-EGFP was constructed.Green fluorescence was observed in Hep-2 cells but not in ECV304. Conclusion: The high specific activity of the survivin gene promoter in Hep-2 cells that we successfully constructed attributes to the studies of tumor specific gene therapy.

Objective To study the prognostic factors of gastrointestinal stromal tumors (GIST).Methods A total of 144 GIST patients treated at the First Affiliated Hospital of Guangxi Medical University between January 1996 and December 2011 were analyzed restrospectively.Kaplan-Meier,log-rank test and Cox regression model were used.Results The overall 5-year survival was 59.6％.Log-rank univariate survival analysis showed that the primary location,tumor size,metastasis,operational method,type of tumor cells,invasion of the surrounding organs and tissues,invasion of the smooth muscle,cellularity of the tumor,mitotic counts of the tumor cells,Ki-67 labeling index,P53 expression and targeting therapy were significant prognostic factors (P ＜ 0.05).Cox regression model showed that tumor size,metastasis,operational method,surrounding organs and tissues invasion,cellularity of the tumor,mitotic counts of the tumor cells,P53 and targeting therapy were essential to improve the survival.Conclusions The study suggests that early diagnosis and comprehensive treatment consisting of operation and targeting therapy can significantly improve the survival of GIST.

Macrophages are heterogeneous and diversified, and can be polarized into different phenotypes in various microenvironments and physiological or pathological conditions. Major macrophage subpopulations including classically activated(M1) and alternatively activated(M2) macrophages, which represent different surface receptors, secret different cytokines and chemokines, are regulated by different signal paths of transcriptions and epigenetic levels, and play distinctive roles in tumor progress. TCMs may improve the microenvironment by regulating phenotype polarization of macrophages. So far, specific biomarkers and polarized molecules mechanisms generated through the macrophage polarization approach are still unclear. In this article, we merely summarize the advance in domestic and foreign studies on phenotype polarization of macrophages and regulatory mechanisms and look into the future of intervention with TCMs.

Objective To investigate the risk factors for ischemic stroke in Uygur population in Xinjiang, China. Methods Using a case-control study mode, 504 Uygur patients with first-ever ischemic stroke and 507 Uygur healthy subjects w ere investigated in accordance w ith the principle of the ethnic, sex, and age matching. The risk factors for ischemic stroke w ere screened. Results Multivariate logistic regres-sion analysis showed that the obesity (odds ratio [OR] 4.82, 95% confidence interval [CI] 1.80-12.94;P=0.002), hypertension ( OR 8.20, 95%CI 4.93-13.51; P<0.001), and heart disease ( OR 2.40, 95%CI 1.07-5.39;P=0.033) w ere the independent risk factors for ischemic stroke in Uygurs. While the education level of junior high school or above ( OR 0.38, 95%CI 0.18-0.81;P=0.012), tea drinking habit ( OR 0.22, 95%CI0.06-0.70; P=0.021), siesta habit ( OR 0.38, 95%CI 0.24-0.59; P<0.001), high levels of high-density lipoprotein cholesterol ( OR 0.34, 95%CI 0.20-0.59; P<0.001), and apolipoprotein A ( OR 0.23, 95%CI 0.07-0.77; P=0.017) were the protective factors for ischemic stroke. Conclusions The risk factors for ischemic stroke are more and typical in Uygur population in Xinjiang, China. Adjusting the diet structure of Uygurs, less taking meats and high-salt diet, intaking high fiber foods and fish, and appropriate physical exercise w il play an important role for the prevention of stroke in Uygur population.

Objective To investigate the level of serum macrophage migration inhibitory factor (MIF) and its correlation with serum precollagen Ⅲ peptide (PⅢP) and tissue inhibitor of metalloproteinase (TIMP)-1 in patients with chronic hepatitis B (CHB) and hepatitis B virus (HBV)-related cirrhosis. Methods Forty-four CHB patients (hepatitis B group), 44 patients with HBV-related cirrhosis (cirrhosis group) and 30 healthy controls (control group) were enrolled in this study. The venous blood was collected and MIF level was detected by enzyme-linked immunosorbent assay (ELISA). Correlations between MIF and PⅢP, TIMP-1 were analyzed in observed groups. Comparison between groups was done using t test. The correlations between MIF level and alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil), plasma thromboplastin antecedent (PTA), PⅢP and TIMP-1 were analyzed by rectilinear correlation. Results The levels of serum MIF, PⅢP and TIMP-1 in CHB group and cirrhosis group were all significantly higher than those in control group (t=12.87,5.28, 10.98,t=11.22,14.84,11.17;all P<0.05), while there were no significant differences between CHB group and cirrhosis group (t= -1.05,1.52,--2.07;all P>0.05). There was no correlation between MIF level and ALT, AST, TBil and PTA. MIF level in CHB patients with hepatitis B e antigen (HBeAg) positive and high viral load were both higher than that in patients with HBeAg negative and low viral load. MIF level was both positively correlated with PⅢP level in CHB group and cirrhosis group (r=0. 603, P<0.05 and r=0. 415, P<0. 05, respectively). MIF level was also positively correlated with TIMP-1 level in CHB group (r=0. 458, P<0.05), while not correlated in cirrhosis group (r=0. 210, P>0.05). Levels of PⅢP and T1MP-1 were both correlated in CHB group and cirrhosis group (r=0. 849, P< 0.05 and r=0. 424, P<0.05, respectively). Conclusions The levels of serum MIF are significantly increased both in patients with CHB and cirrhosis. The early production of MIF might be related with viral replication, but not with liver function. MIF participates in formations of hepatitis, liver fibrosis and cirrhosis, which could reflect the degree of liver cirrhosis.
