Objective To get overview about diarrhea condition of HIV/AIDS cases among paid blood donors in our country. Methods One-to-one questionnaire was adopted to investigate a total of 285 HIV/AIDS cases among paid blood donors in Henan province. Diarrhea HIV/AIDS patients were further picked out according to 'Criteria of HIV/AIDS diarrhea'and their syndrome characteristics were analyzed. Results There was 41 diarrhea HIV/AIDS patients in all 285 HIV/AIDS cases (14.39%). Deficiency Syndrome and mixed insufficiency and excess syndrome were predominant Syndromes in these patients. Conclusion The rate of diarrhea in HIV/AIDS cases among paid blood donors of our country was lower than some foreign countries. Such internal organs as spleen, liver, kidney, stomach and lung were mainly involved in the disease.

The data production and management processes were described and the factors influencing the data pro-cessing quality were analyzed with CMCC/CMCI as an example, and measures were put forward for improving the data production and management-the key to database development.

Objective To study the effects of Tan Ⅱ A on the expression of c-Met and HIF-lα in gastric cancer SGC7901 cells under hypoxia and the correlation between c-Met and HIF-lα expression. Methods The model of hypoxia was established by CoCl2. There were three groups; normal control group, hypoxia control group, and hypoxia combined with different concentrations of Tan ⅡA group. After Tan ⅡA was added to the media with 0.5, 2.0 and 10.0 mg/L respectively for 48 h under hypoxia, the expression of HIF-1α and c-Met protein was detected by immunocytochemical staining. Results Immunocytochemical staining revealed that the expression of HIF-1α and c-Met protein was inhibited by Tan ⅡA in a dose-dependent manner under hypoxia. High positive correlation was found between the expression of HIF-1α and c-Met (n = 4, r = 0. 996, P <0.01). Conclusion Tan ⅡA might inhibit the expression of c-Met protein via down-regulation of HIFlα protein expression under hypoxia, suggesting that Tan ⅡA might play an important role in fighting against hypoxia-stimulated invasion and metastasis of tumor.

Objective To study TCM pattem rules of primary hyperlipemia and its relation with sex,age,body mass index(BMI).Methods A total of 1 20 patients with primary hyperlipemia were divided into 5 groups by TCM syndrome differentiation:56 patients in a group of the turbid-phlegm stagnation syndrome,35 patients in a group of yang deficiency of spleen and kidney syndrome,13 patients in a group of yin deficiency of liver and kidney,7 patients in a group of hyperactivity of yang due to yin deficiency group,and 9 patients in a group of qi stagnation and blood stasis syndrome.Statistic analysis was made on factors that may affect these syndromes,and the correlations were discussed.Results Different age showed a closer relation to the onset of primary hyperlipemia than other factors(P＜0.01):sex,clinical classification,and accompanied diseases had no relation with the five-type syndromes(P＜0.01).Conclusion TCM syndromes had a certain relation with the age of patients with primary hyperlipemia.

Objective: To probe into TCM pattern of primary hyperlipemia and its relationship with gender, age, BMI, laboratory indices such as TC,TG, LDL-C, HDL-C, ApoAI, ApoB of the 120 patients with primary hyperlipemia. Methods: Logistic regression analysis wan used to analyze the associativity of TCM syndrome and objective indexes of primary hyperlipemia. Results: Logistic regression analysis showed that TCM syndromes of primary hyperlipemia had some relation with laboratory indices. Conclusion: TCM syndromes of primary hyperlipemia had some relation with laboratory indices. The lipemia laboratory indices can be one of the objective basis of TCM diagnosis. The main syndromes were stagnation of phlegm-turbid and syndrome of yang deficiency of both of spleen and kidney, the main pathogenesis were deficiency of spleen and kidney, intermingled phlegm and blood stasis. The main treatment methods were invigorating spleen and tonifying kidney, supplementing qi and nourishing heart, promoting blood flow and dissipating phlegm.

Objective To research the effects of drought stress on activity of key enzyme in saikosaponin biosynthesis and saponins content in Bupleurum chinense; To reveal response of Bupleurum chinense to drought stress from protein level. Methods Bupleurum chinense was cultivated in potted water control experiment with 70%–80%, 60%–70%, 40%–50% and 20%–30% saturated soil water contents. The enzyme activities of 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase (HMGR), isoprenyl-based coke (IPPI), farnesyl pyrophosphate synthase (FPS) and β-carotenoid synthase (β-AS) of six months and one year old Bupleurum chinense were measured. The contents of saikosaponins a and d in samples of different soil water contents were determined by HPLC. Results When the saturated moisture was 40%–50%, the enzymatic activities of HMGR, IPPI, FPS and β-AS were the highest, followed by saturated moisture 60%–70%、70%–80% and 20%–30%. The trend of saikosaponin was similar to that of the activity of key enzyme. Conclusion 40%–50% soil saturated water content can significantly increase the activity of the key enzymes in the saikosaponin synthesis pathway. The saponin content and enzyme activity show a significant positive correlation, indicating that under drought stress, Bupleurum chinense regulates the synthesis of saikosaponin by regulating the key enzyme activity of saikosaponin synthesis pathway to respond drought stress.

Objective To compare the scores from the simpliifed COMFORT scale with those from the bispectral index (BIS) and analyze the variation among different evaluators in children in an intensive care unit, and to investigate the reliability;validity of simpliifed COMFORT scale. Methods Twenty children between 3 and 16 years of ages on mechanical ventilation and sedation were simultaneously classiifed based on the BIS and the simpliifed COMFORT scale evaluated by 4 independent evalua-tors. The Kappa test was performed and the correlation between the two methods (Pearson correlation) was tested. Results In to-tal, 70 observations were performed on 20 patients. Based on the Kappa coefifcient, the agreement among evaluators ranged from 0.62 to 0.77 (P<0.001). There was a correlation between the BIS and the simpliifed COMFORT scale (r=0.53-0.61,P<0.01). Conclusions Due to the strong consistency between the independent evaluators and the correlation between the two methods, the reliability and validity of simpliifed COMFORT scale are preferable and simpliifed COMFORT scale is useful in classifying the level of sedation in children on mechanical ventilation.

Objective To explore the construction method of semantic types of military medical ontology and to establish a framework for the semantic types of the top-level ontology of military medicine in order to lay the foundation for the construction of military medical ontology and provide support for knowledge organization, knowledge disclosure and knowledge service of military medical information resources.Methods Using the method of document measurement, the core concept set of military medicine was constructed.On the basis of the framework of the top-level semantic types of Unified Medical Language System(UMLS), the semantic type framework was completed by the combination of bottom-up and top-down modes, using semantic analysis and expert consultation.Results By classifying the same kind of knowledge points of military medicine into one semantic type, the hierarchical structure of the semantic type framework of the top-level ontology of military medicine was obtained.Conclusion The proposed method is effective and practical for the construction of the semantic types of military medical ontology.The established semantic type framework of the top-level ontology of military medicine could reconstruct military medical knowledge and provide the basic framework for the establishment of the semantic relationships of the top-level ontology of military medicine.

Objective To analyze the use of the semantic type of the top-level ontology of military medicine in order to find problems with the semantic type framework and make it more scientific and comprehensive.Methods Using data driven method, the frequency with which the semantic type of the top-level ontology of military medicine was used in military medical core concepts was statistically analyzed.Results By ranking the use frequency of the semantic types, the semantic types which had higher or lower frequency, and those that had never been used were analyzed.Conclusion The established semantic type framework of the top-level ontology of military medicine is basically consistent with the expression of military medical knowledge and can be constantly updated and improved with the development of military medicine.
