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: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.

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.

BACKGROUND:Impact mechanics properties of thoracic vertebra cancellous bone should be understood in treating osteoporosis,bone remodeling,bone reconstruction,as well as fixator selection for thoracic vertebral fracture.Most of previous studies concerning youth and the elderly bodies alone,reports regarding impact of thoracic vertebra cancellous bone mechanical properties are few.OBJECTIVE:To perform impact experiment to the normal people youth and the elderly fresh corpse thoracic vertebra cancellous bone to survey the impact mechanical properties,and to definite whether the impact mechanical properties of thoracic vertebra trabecular bone have difference between youth and the elderly people.METHODS:Experimental samples were from 4 normal fresh corpse,aged 20,25,70 and 75 years,were provided by Department of Anatomy,Norman Bethune Medical University.Spinal column thoracic vertebra T_(3-12) specimen were obtained from corpse within 1 hours and cut into 40 mm×6 mm×6 mm pieces,with 20 test pieces in each group.The impact experiment was performed using energy liberation method at room temperature under 28 ℃.After experiment,the impact energy was displayed automatic on testing machine,and the impact toughness was calculated by mechanical formula,and the morphology of fracture surface was observed.RESULTS AND CONCLUSION:The impact energy and impact toughness of the youth group was obviously greater than that of the elderly group (P＜0.05).Majority of the fracture surfaces were comminuted,minority were transverse or oblique fracture.The macroscopic observation showed that trabecular arranged compact in the thoracic vertebra cancellous bone of the youth group,which was sparse arrangement and presented with senile osteoporosis in the elderly group.It demonstrated that the impact mechanics properties of thoracic vertebra cancellous bone are different between the youth and elderly groups,and osteoporosis changes impact mechanics properties in the elderly people.

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.

OBJECTIVE:To provide reference to promote the proper use of TCM decoction pieces.METHODS:According to Beijing TCM Decoction Piece Dispensing Regulation,stratified random sampling method was adopted to select a group of physicians in our hospital and conduct questionnaire survey about their knowledge of the prescription handling of 8 commonly used TCM decoction pieces including Scutellaria baicalensis,Angelica sinensis,Fritillary,Phellodendron chinense,Aconitum carmichaeli,Eucommia ulmoides,Ziziphus jujuba,Rhei Radix et Rhizoma.Then,the survey data was collected and analyzed.RESULTS:A total of 81 questionnaires were given out and all were returned with effective recovery rate of 100％.In terms of professional titles,associate chief physicians showed the lowest average error rates in prescription handling cognition (27.5 ％),compared with physicians (35.8％) and attending doctors (37.0％).They made most mistakes about Fritillary and E.ulmoides.To the contrary,both physicians and attending doctors made most mistakes about E.ulmoides.In the scope of working life,physicians from different groups showed similar average error rates in prescription handing recognition (31.3％-38.8％).All of them made most mistakes about P.chinense and E.ulmoides.As for major,those who study western internal medicine shared larger average error rates (43.8％) than those who study internal medicine of TCM (36.8％),traumatology and orthopedics of TCM (31.8％) and acupuncture (36.5％).Each major showed the highest error rates in E.ulmoides.The order of 8 TCM decoction pieces from the most mistakes to the least mistakes made by physicians was E.ulmoides,P.chinense,Fritillary,Rhei Radix et Rhizoma,S.baicalensis,A.carmichaeli,Z.jujuba and A.sinensis.CONCLUSIONS:Physicians with different professional titles,working life and majors show deficiency in knowledge about the prescription handling of 8 commonly used TCM decoction pieces.Generally,physicians show the worst understanding of E.ulmoides.
