Objective:To perform textual researches on name, origin and distribution of Maidong to clarify the medicinal varieties and history recorded in ancient literatures and provide evidence for clinical use. Methods:Ancient herbal works were performed textual research, and the resource investigation and modern data were analyzed. Results:According to the ancient herbal records and modern researches, Maidong had lots of alias, while only Maimendong and Maidong were used as the medicine common names. According to the records of main origin, original plant morphological and medicinal characteristics of Maimendong, it was preliminarily concluded that Maidong recorded in the ancient herbal records was mainly produced in Jiande of Zhejiang province, Mianyang of Sichuan prov-ince, Xiangyang of Hubei province and the surrounding areas. The chemical compositions and pharmacological activities of Maidong and Shanmaidong were similar;therefore, they both could be used as the medicines. Conclusion:In the light of the ancient and mod-ern medicinal customs, modern chemistry and pharmacology researches and clinical practice of TCM, it deserves further discussion on whether Maidong and Shanmaidong can be used as multi source varieties of traditional Chinese medicines just like Polygonaceae plants palmatum L. , Rheum tanguticum Maxim, ex Balf. and Rheum officinale Baill. , and Ranunculaceae plants Coptis chinensis Franch. , Coptis deltoidea C. Y. Cheng et Hsiao and Coptisteeta Wall.

Objective To investigate the prognostic factors of gastrointestinal stromal tumors.Methods From Nov.1999 to Dec.2006,a total of 85 patients were diagnosed by postoperative pathology as gastrointestinal stromal tumors.The relationship between the prognosis of GIST and demographic factors、tumor location、operation style、preoperative metastasis、lymphadenectomy、grading of Fletcher were analyzed retrospectively.Results The 1 year、3 year and 5 year survival rate of these 85 patients were 94%,60%,57%respectively,Univariate analysis indicated that tumor location、operation style、grading of Fletcher and preoperative metastasis were significant predictors of survival(P<0.05),while demographics and lymphadenectomy were not statistically related with prognosis.Multivariate analysis showed that preoperative metastasis was the independent factor predicting the prognosis(P=0.020,β=4.226).Conclusion Radical surgical excision is still the therapy of choice for primary gastrointestinal stromal tumors.Preoperative metastasis is the independent factor predicting poor prognosis,therefore early diagnosis and treatment are very important for GIST.Fletcher grading is also a simple recalls to predict the prognosis of GIST.

The purpose of this study is to obtain effective and stable bacteriocin-like substance from lactic acid bacteria. Lactobacillus buchneri KLDS1.0364,which was isolated from fermented cream,a traditional dairy product in Inner Mongolia,could produce bacteriocin-like substance. The bacteriocin-like substance produced by KLDS1.0364 was partially purified and the characteristics were studied. The bacteriocin-like substance was purified by SP-Sepharose fast flow cation exchange chromatography. The molecular weight of the bacteriocin-like substance was 21.6kD,as determined by tricine-SDS-PAGE. The bacteriocin-like substance remained stable after 30 min at 121℃ and after 2 h of incubation during pH 2~10. Complete inactivation of antimicrobial activity was observed after treatment of the bacteriocin-like substance with several proteinases. Treatment with catalase and ?-amylase did not result in any changes of antimicrobial activity. The mode of action of the bacteriocin-like substance is bactericidal. It exhibited a broad spectrum of antagonistic activity against various species of Gram-positive bacteria,Gram-negative bacteria and fungi.

Purpose:Taking tuberculosis as an example, this paper aims at to analyzing the level of reimburse-ment for infectious diseases care, and clarifying the government responsibility. Methods:In order to achieve the ob-jective of this research, UHC framework was used to analyze the security level. Result:The findings of this research reveal that TB in-patients' Compensation Ratio of the New Cooperative Medical Scheme ( NCMS) was lower than aver-age level of all the NCMS patients, the out-patients' was even lower. The categories of anti-tuberculotic for free was limited, the utilization was not as expected. Medical assistance covered few people in spite of its high level of reim-bursement. Conclusion:Based on the findings of this review, it has been revealed that the medical insurance didn't make a big difference in financial protection for patients with infectious diseases. As the treatment for of infectious diseases is a quasi-public good, the government has to shoulder the responsibility of improving the compensation ratio of the patients.
