Fructus Xanthii is commonly used in rhinology, especially used in treatment of chronic rhinitis and sinusitis. But Fructus Xanthii is toxicant, and it maybe result in poisoning when used excessively, without preparation or in inappropriate preparation. This article reviewed all poisoning cases from 1960 to 2000, its toxicology and methods for detoxification

Traditional Chinese medicine teaching in general medical university was unsatisfied under the influence of many problems such as indefinite purpose,few class hours but many teaching contents,the different theoretical system between traditional Chinese medicine and western medicine,and theory divorced from practice etc.Therefore,the author suggested several measures that may help increasing teaching quality such as making definite course purpose and stimulating students' learning interest,enhancing training of imagery thinking,carefully electing teaching contents,integrating theory with practice and increasing clinical practice etc.

Objective To observe the clinical effects of treating Vetigo due to Vertebrobasilar Insufficient blood supply and hyperactivity of liver-Yang with Tianzhi Granules. Methods 118 cases were randomly recruited into a treatment group with 62 cases and a control group with 56 cases. On base of routine treatment, the treatment group was treated with Tianzhi Granules orally; and the control group was treated with Duflomed Hydrochloride orally. One course of treatment was 14 days. Results The total effective rates were 96.77%and 78.57% in treatment group and control group respectively. There was a significant difference between the two groups(P<0.05). The blood flow rat(BFR)of brain was improved in both groups, but the improvement of the BFR in brain was significantly better in the treatment group than the control group (P< 0.05). No adverse reaction was found in the treatment group. Conclusion Tianzhi Granules is effective and safe in treating Vetigo due vertebrobasilar insufficient blood supply.

OBJECTIVE：To establish a method for determination of baicalin in QiLiKeGanKang oral liquid.METHODS：The RP-HPLC method was employed taking Nova-pak C18 column as fixed phase and methanol-water-phosphoric acid(45∶ 55∶ 0.2)as mobile phase.Detection wavelength was 280 nm.RESULTS：The detection ranges were 0.179μ g～1.434μ g.The average recovery of baicalin was 101.35％ (RSD=2.40％，n=5).CONCLUSION：This HPLC method is convenient，rapid，accurate and could be used for quality control in the production of QiLiKeGanKang oral liquid.

OBJECTIVE:To provide reference for AIDS vaccine R&D in China through investigating AIDS vaccine patent ap-proval in America. METHODS:By combining keywords as HIV vaccine(s),AIDS vaccine(s) and Vaccine of HIV(AIDS) and classification number as A61K,A61P and C12P,related patents were retrieved from Thomson Innovation platform during Jan. 1981-Mar. 2015,and then analyzed in respects of patent data,patent approval trend,R&D ability,patent technology field distribu-tion,etc. RESULTS:A total of 1 272 patents were retrieved,including 405 valid patents. From 1985 to 2014,there were three stages for the change of AIDS vaccine application quantity,which were slow rise,fast rise and slow decline period;on the whole, the trend was on the rise. The main players were Duke University,United States Department of Health and Human Services,Pas-teur Institute,Connaught Laboratories Limited and Merck Group. AIDS vaccine R&D focused on pharmaceutical preparation,thera-peutic activity of medicinal preparations,microorganism,enzyme,etc. American scientific research institutions focused more on pharmaceutical preparation and peptide study. CONCLUSIONS:Though the AIDS vaccine field develops slowly,the future is still promising. In this field,America has stronger patent advantage and scientific research strength. AIDS vaccine R&D concentrates on pharmaceutical preparation,therapeutic activity of medicinal preparations and composition.

Objective To investigate the effect of Bushen-Tongmai decoction on plasma renin activity (PRA), plasma levels of brain natriuretic peptide (BNP) and angiotensinⅡ(AngⅡ) in patients with chronic heart failure. Methods A total of 100 patients with chronic heart failure from January 2011 to December 2013 were randomly divided into a control group and a treatment group, with 50 patients in each group. The patients in the control and treatment groups received conventional treatment and Bushen-Tongmai decoction plus conventional treatment for 8 weeks, respectively. Laboratory measurements including PRA, BNP and AngⅡwere performed before and after treatment.Cardiac function was measured before and after treatment with echocardiography. Results The PRA , plasma levels of BNP and AngⅡ after treatment in the treatment group were significantly decreased than before treatment (treatment group:t=2.990, 4.030, 4.401, all P<0.01);after treatment, there was significant difference in PRA, BNP and AngⅡbetween the treatment group and the control group(t=2.622, 2.863, 3.809, all P<0.05). Left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD) and left ventricular ejection fraction (LVEF) by echocardiography in both groups were significantly improved (treatment group:t=9.167, 11.030, 13.273, all P<0.01;control group:t=5.189, 7.626, 6.906, all P<0.01). Improvements of LVESD, LVEDD and LVEF in the treatment group were grater than those in the control group (t=4.037, 2.701, 7.458, all P<0.01). Conclusion Bushen-Tongmai decoction can effectively decrease PRA , plasma levels of BNP, AngⅡ, and improve cardiac function in patients with chronic heart failure.

Mucosa-associated lymphoid tissue (MALT} lymphoma is a low grade B-cell lymphoma arising from MALT of extra-nodal. A link of Helicobacter pylori (HP) infection with gastric MALT lymphoma was confirmed in the early years. Currently, growing evidence indicates that development of non-gastric MALT lymphoma is also associated with infections by microbial pathogens. t(l1;18)(q21;q21)、t(l;14)(p22;q32) and t (14;18)(q32;q21) are specifically associated with MALT lymphoma, which occur at variable incidences in MALT lymphoma of different sites. The oncogenic activity of these three chromosome translocations is linked by antigen receptor-mediated NF-κB activation.In addition, a number of novel genetic abnormalities have been recently identified in MALT lymphoma. The findings of these microbial pathogens and molecular genetics would be helpful in better understanding the pathogenesis of MALT lymphoma and also useful for the diagnosis at early stage and proper treatments of MALT lymphoma.

Objective To understand the basic experimental teaching of functional science in order to promote transformative learning. Methods Random sampling questionnaire survey was con-ducted among 274 students (2011 grade, 5-year-program) majored in clinical medicine, medical lab-oratory and medical imaging in Kunming Medical University. Investigation primarily aimed at the stu-dents' learning attitude, learning objectives, and teaching content. Excel 2003 was used for data en-try, percentage of each questionnaire option was calculated and the findings were directly described. Results 94.76%(253/267) students preferred basic experiment; 82.40%(220/267) students hoped to open long term laboratory;97.38%(260/267) students thought that basic experiment could help pro-mote understanding and theoretical knowledge of physiology; 98.50%(262/267) students thought the explain of the basic theories and the operation prior to each experiment were good; 78.27%(209/267) students were willing to strengthen the basic operation while only 59.18%(158/267) students would like to analyze the experiment results. Conclusions Basic experiment of functional science is wel-comed by students. Due to the lack of independent thinking ability of students, experiment course should de designed to promote interest-oriented transformative learning and to culture transformation perspective, finally achieving the transformative learning.
