European Society of Hypertension/European Society of Cardiology jointly published new guidelines on diagnosis and treatment of hypertension in 2007.It reflected the the latest developments on comprehensive assessment,treatment modalities and strategies,as well as therapeutic approach for special populations.In addition,the new guidelines updated evaluation.It also stressed the importance of an early,faster and more stringent treatment and aggressive combination therapy.More impartantly,it requested prevention and treatment earlier.It is of great importance for the guidelines to guide the current diagnosis and treatment of hypertension.

OBJECTIVE:To facilitate a better understanding of the European Union(EU)herbal drugs market for Chinese TCM enterprises and to promote the internationalization of Chinese traditional medicines.METHODS:The opportunities and challenges confronted by TCM enterprises in their expanding of their products in the EU herbal medicine market were analyzed based on the knowledge about market size,market segmentation,consumption patters and developmental tendencies of the EU herbal medicine market.RESULTS&CONCLUSIONS:There were both opportunities and challenges for the expanding of traditional Chinese medicines in the EU herbal medicine market,yet on the whole,the opportunities were more than the challenge.Chinese enterprises should strive to further expand the EU herbal medicine market.

OBJECTIVE:To promote the reasonable use of antibiotic drugs.METHODS:the causes of antibiotics drug abuse were analyzed.The regulation on standardizing antibiotic drug sales by State Food and Drug Administration as well as its influence were discussed.RESULTS&CONCLUSION:some conceptions and suggestions are tentatively put forward.

OBJECTIVE:In order to enhance the quality control of Chinese botanical extracts and to facilitate the entry of Chinese botanical drugs and traditional Chinese medicine into the international market.METHODS:The market overview of the botanical extracts was expounded,problems existed in the quality control of the Chinese botanical extracts were analyzed,and the significance and key points in establishing Good Extracting Practice(GEP)of the traditional Chinese medicine were discussed.RESULTS&CONCLUSION:The quality control of the Chinese botanical extracts must be emphasized,which means to establish the feasible quality standard;the production process should be optimized and the corresponding‘Standard Operating Procedure’should be formed;advanced technology and facilities should be adopted to improve the content of hi-tech,the toxic substances should be strictly controlled;the quality of the raw material should be guaranteed,the connection between which and the‘Good Agricultural Practice for Chinese Crude Drugs'should be strengthened.

OBJECTIVE:To provide references for the expanding of Chinese traditional medicine enterprises in USA market.METHODS:The management mode of the botanical preparations in the USA and the related laws and regulations were overviewed from the perspectives of dietary replenisher and drug areas.RESULTS&CONSCLUSION:For the entry of Chi?nese traditional medicine into the USA market,a realistic way of behavior for the time being is to adopt a step-by-step pol?icy,i.e.first of all,a research of the standard botanical extracts should be conducted before entering into the USA market in the status of dietary replenishers,then the clinical research application was raised after marketing in USA market for several years,eventually,new drug application was raised.

ObjectiveTo study the effect of allo-human bone marrow mesenchymal stemcells (bMSCs) on the secretion of interleukin(IL)-1, tumor necrosis factor(TNF)-α and transforming grouth factor (TGF)-β of patients with rheumatoid arthritis (RA) in vitro. MethodsBMSCs were isolated from bone marrow of healthy volunteers and purified by density gradient centrifugation and cultured in vitro. The mononuclear cells from the peripheral blood of patients with RA and healthy controls were isolated respectively.bMSCs and mononuclear cells were co-cultured in vitro and the density of IL-1, TNF-α and TGF-β3 in the co-culture system were detected by ELISA. ANOVA and Pearson correlation were used for statistical analysis.ResultsMononuclear cells from peripheral blood of patients with RA were co-cultured with bMSCs for seven days. There were an decreased density ofIL-1[(38.4±0.5) vs(6.2±1.0) ng/L], TNF-α[(29.4±1.3) vs (4.6±1.2) ng/L]and an increased density of TGF-β[(2.6±1.0) vs (22.5±2.2) ng/L]in the co-culture system (P＜0.05). But on the other hand, for healthy volunteers there were no significant change in the density of IL1[(4.4±1.1) ng/L]and TNF-α[(5.0±1.7) ng/L]in the coculture group, as compared with the mononuclear cell group[(4.4±1.3) vs(5.3±1.7) ng/L](P＞0.05). There was an increased density of TGF-β in the coculture system[(4.8±1.4) vs(10.5±1.2) ng/L](P＜0.05). IL-1 was positively correlated to TNF-αt (r=0.896,P=0.000), TNF-β1 was nagative correlation with 1L-1 and TNF-α (r=-0.356,P=0.019; r=-0.380,P=0.000).ConclusionHuman bone marrow MSCs have modulatory effects on main cytokines of patients with RA in vitro. bMSCs could down-regulate the levels of IL-1 and TNF, but up-regulate the density of TGF-β. These immune-modulatory effects are not MHC restricted. The results of this study have provided evidence for the development of effective therapy for RA.

Objective To investigate the clinical value of fecal calprotectin as a marker for diagnosis of ulcerative colitis(UC).Methods ELISA assay was used to measure the concentrations of calprotectin in feces of 30 UC patients and 20 healthy controls.The disease activity of UC was determined by Truelove Witts histological criteria.Results The level of calprotectin in feces was significantly higher in feces with active UC(578?g/g) than with inactive UC(8.4?g/g,P0.05),but significant difference existed between each active grade and inactive phase of UC.The results revealed siginificant correlation between the endoscopic grades of disease activity and fecal calprotectin concentration(r=0.85,P

Objective To detect the levels of Th1 and Th2 type cytokines of peripheral CD+4 T lymphocytes in patients with colonic cancer in order to find out the significance of variance of imbalance in clinical therapy.Methods The peripheral blood lymphocytes were stimulated by stimulator in order to enhance the expression of cytokines.Then a specific fluorochrome-conjugated monoclonal antibody was added to be combined with its specific antigen.Cytokines were detected by flow cytometry.Results The levels of Th1 type cytokines such as interferon-γ/(INF-γ),interleukin-2(IL-2)were significantly lower in patients of colonic cancer than those of normal controls.The levels of Th2 type cytokines such as interleukin-4(IL-4),interleukin-6(IL-6)and interleukin-10(IL-10)were higher in patients of colonic cancer than those of normal controls.Conclusion Th1/Th2 shihs in colonic cancer.It is suggested that the levels of INF-γ/IL-4 in colonic cancer may provide clinical index for the prognosis and evaluation of immunity.

Objective: To review clinical characteristics of cardiac and pericardial hydatid cysts and assess the results of surgical treatment. Methods: From February 1978 to July 1999, 13 patients were diagnosed as heart and/or pericardium echinococcosis. There were nine male and four female. Their age ranged from 8 to 36 years ［mean (23.0±8.5) years］. 10 patients were symptomatic and 3 were asymptomatic. 3 patients had involvement of liver or lung. Pathologic cardiac murmur or cardiac enlargements were found in 10 patients. All patients were examined with chest roentgenograms, electrocardiogram and echocardiography. The serologic test was positive in 11 cases and negative in 3 cases. One right atrial cyst was removed under extracorporal circulation. 4 single pericardial cyst and multi-pericardial cyst were resected, 6 myocardial cysts and one complicated myocard ial and pericardial cysts were resected through puncture-aspiration endocystect omy. Results: All patients were followed up from six months to six years ［mean (3.5±1.5) years］. One late death occurred ten-month after operation, and the cause of death was heart failure. 3 patients had recurrence and were reoperated. Conclusion: The clinical characters may vary according to the number, size and location of cysts. Echocardiography is important for surgical planning. The results of endocystectomy of cardiac and pericardial echinococcosis were excellent.
