Tuberculosis (TB) is a global burden disease and is being resurrected as a major worldwide public health problem after two decades of neglect.In 1993,the World Health Organization (WHO) declared that TB had been a global emergency because of the scale of the epidemic and the urgent need to improve global tuberculosis control.China is one of the countries with the largest population,and also the top of the 22 TB high-burden countries in the world.In the United States,the longstanding downward trend in TB incidence was interrupted in the mid-to-late 1980s,where the national TB incidence peaked in 1992.Sub-Saharan Africa is one of the three regions to dominate the worldwide distribution of notified TB cases.Of the 15 countries with the highest estimated tuberculosis incidence rates in the world,13 are in sub-Saharan Africa,where HIV is the most important single predictor of tuberculosis incidence.The largest share of the global burden of HIV-related tuberculosis falls on this region.The reasons for the persisting global tuberculosis burden include increased poverty in some regions,immigration from countries with high tuberculosis prevalence,the impact of HIV,and most importantly,the failure to maintain the necessary public health infrastructure under the mistaken belief that tuberculosis was a problem of the past.Relying on currently available methods of diagnosis and treatment,the DOT strategy promoted by the WHO for global tuberculosis control is effective,affordable,and adaptable in different settings.

To establish the water dynamics model for drying process of Angelicae Sinensis Radix, the Weibull distribution model was applied to study the moisture ratio variation curves, and compared the drying rate and drying activation energy with the drying methods of temperature controllable air drying, infrared drying under different temperatures (50, 60, 70 degrees C). The Weibull distribution model could well describe the drying curves, for the moisture ratio vs. drying time profiled of the model showed high correlation (R2 = 0. 994-0. 999). The result proved that the drying process of Angelicae Sinensis Radix belonged to falling-rate drying period. For the drying process, the scale parameter (a) was related to the drying temperature, and decreased as the temperature increases. The shape parameter (β) for the same drying method, drying temperature had little impact on the shape parameter. The moisture diffusion coefficient increase along with temperature increasing from 0.425 x 10(-9) m2 x s(-1) to 2.260 x 10(-9) m2 x s(-1). The activation energy for moisture diffusion was 68.82, 29.60 kJ x mol(-1) by temperature controllable air drying and infrared drying, respectively. Therefore, the Weibull distribution model can be used to predict the moisture removal of Angelicae Sinensis Radix in the drying process, which is great significance for the drying process of prediction, control and process optimization. The results provide the technical basis for the use of modern drying technology for industrial drying of Angelicae Sinensis Radix.

To provide a scientific basis for the selection of the appropriate drying method for Mentha Haplocalyx Herba (MHH), determine 2 monoterpenes, 4 phenolic acids and 5 flavonoids in MHH by GC-MS and UPLC-TQ-MS methods, and investigate the effects of the drying methods on the changes in contents of these analytes. The qualities of products obtained with different drying methods were evaluated by the multivariate statistical method of Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). Results showed that the drying methods had the greatest impact on menthol, caffeic acid, and rosemary acid, which were followed by chlorogenic acid and diosmetin-7-O-glucoside. The contents in these analytes processed with hot-air-drying method were higher than those with microwave-drying and infrared-drying methods at the same temperatures. The contents in these analytes processed under low temperature (40-45 °C) were higher than those under higher temperature (60-70 °C). Above all, the contents in phenolic acids processed with microwave fixation (exposed under microwave at 100 °C for several minutes) were obviously higher than those of not being processed, showing an inhibition of some enzymes in samples after fixation. The TOPSIS evaluation showed that the variable temperature drying method of 'Hot-Air 45-60 °C' was the most suitable approach for the primary drying processing of MHH. The results could provide the scientific basis for the selection of appropriate drying method for MHH, and helpful reference for the primary drying proces of herbs containing volatile chemical components.

An evidence-based practice method according to literature retrieval through PICO (Patients, Intervention, Comparison, Outcome) questions and complementary and alternative medicine (CAM) topics, which can obtain helpful evidence for guiding clinical practice, was introduced with a practical example in this paper. The knowledge of diseases and Western medicine treatment can be acquired by literature retrieval through PICO question, while searching by CAM topics may provide evidence for Chinese medicine (CM). Thus the author held that literature retrieval through both PICO question and CAM topics was an ideal evidence-based practice method for integrative Chinese and Western medicine (ICWM). However, since the standard in CM evidence hierarchy is still under study, the value of the CAM thematic retrieval method remains very limited. In the future, studies on the definition and hierarchy of CM evidences and the herb-drug interaction between Western and Chinese medicine during a combination therapy should be strengthened to improve the status of ICWM evidence-based practice.

OBJECTIVETo evaluate the efficacy and safety of "Three-Typed Syndrome Differentiation" (TTSD) in treating type 2 diabetes mellitus patients.

METHODSA systematic review and meta-analysis was done based on the clinical diabetes treatment literature of the "TTSD". Overseas databases like the PubMed/MEDLINE, EMBASE, Cochrane Library and Cochrane Central Register of Controlled Clinical Trials, and China databases like China Biology Medicine Disc (CBM), Chinese national Knowledge Infrastructure (CNKI), Wanfang database, and VIP database, without limitation on language, were included with the time limitation from Jan 1982 to Dec 2012 by retrieval of relative original clinical research articles.

RESULTSNineteen articles where contains 1,840 diabetes patients were obtained, in which no adverse reactions were reported. Of these, 14 literatures involved the effect of fasting blood glucose (FBG), 10 involved that of postprandial 2-h blood glucose (P2hBG), and 19 involved the overall efficacy based on the national Chinese medicine (CM) diagnosis and treatment standard of diabetes. All the meta-analysis results prefer to the "TTSD" groups (CM+Western medicine Based on TTSD). The results show that, beside the efficacy of Western medicine, the concentrations of FBG and P2hBG in "TTSD" groups continue to drop with statistical significance. For "TTSD" groups, the FBG subsequently dropped 1.03 mmol/L, 95%CI [1.24,0.82] P <0.00001), the P2hBG subsequently dropped 1.09 mmol/L, 95% CI [1.61, 0.57] (P <0.0001), and the overall efficacies benefit 3.46 times those of Western medicine alone, 95% CI [2.67,4.48] (P <0.00001).

CONCLUSIONSThe CM by the diagnosis and treatment of type 2 diabetes based on TTSD might be safe and effective, and could better improve both blood glucose and the overall status of patients, including symptoms.

Opioid receptor, is classified into three subtypes, mu, kappa and delta, with the mu-type receptor plays important roles in opioid analgesia and opioid addiction. The cDNA encoding mu-type receptor was obtained by RT-PCR from human brain RNA and was cloned into pcDNA3.1(+). The resultant recombinant plasmid pcDNAMORs were transfected into CHO cells by liposome. After PCR identification, the positive clone were treated with agonist and antiagonist were tested for their competence of signal transduction. CHO cells that contained mu-opioid receptor in the expression vector pcDNA3.1(+) acquired naloxone-blockable high-affinity specific binding of morphine and DAMGO. The concentration of cAMP in CHO cells transfected with pcDNAMOR was reduced after binding to morphine and DAMGO, and increased after binding naloxone. These results indicate that the mu-type receptor expreesd on the CHO cell has similar biological property as the nature receptor. The availability of these specific cell lines will facilitate the drug development and promote our understanding the mechanism underlying opiate addiction.
