Isolated alkaloids from Coptis chinensis Franch. The compounds were identified as berberine, columbamine, groenlandicine, jatrorrhizine, magnoflorine, corydaldine and ferulic acid methylester. Then measured their bitter degree based on the electronic tongue and evaluated the antibacterial. The results based on the Electronic Tongue showed that berberine, columbamine, groenlandicine and jatrorrhizine have higher bitter degree than magnoflorine and corydaldine. And they also appeared better antibacterial activity on E. coli and S. aureus. The correlation coefficients between bitter degree and the two bacteria antibacterial activity were 0.983 and 0.911. So there was close relationship between the bitter degree and antibacterial activity of bitter components. Thus, it is confirmed further that bitter components are the material foundation of medicinal effectiveness of bitter herbs.

Through retrieval of all medical journals of CNKI and VIP from Jan. 1996 to Oct. 2012, ninety-nine articles were selected and analyzed. The result shows that reliable effect can be found in pain relieving, especially in pain of muscles and soft tissues. In mechanism research, action mechanism of Fu's subcutaneous needling (FSN) on pain relieving is expounded through theory of traditional medicine and modern medicine. Although the effect of FSN on pain relieving has been confirmed by numerous clinical trials, it is still lack of explanation on mechanism revealing. The further studies should focus on mechanism expounding, improving research methods and selecting more objective and reasonable evaluation system. Therefore, the effectiveness and scientificalness of FSN can be further enhanced.

OBJECTIVE To enhance the rational usage of antibiotics by comprehensive interventional measures in clinics.METHODS Several interventional measures have been adopted in our hospital since January 2001: to(establish) expert team on antibiotics usage and administration consultation;constitute antibiotics use criteria(suitable) for each clinical specialty;train and examine the usage of antibiotics;censor the distribution of pathogen and drug-resistance variance.Then 10% of the discharged medical records in 2000,2002 and 2004 were drawn out respectively to analyze the usage of antibiotics and the isolation of pathogen from nosocomial infection cases.(RESULTS) The proportion of the patients with prophylactic and remedial indications was increased remarkably((P

Objective To investigate the effects of 3 different ventilation methods,including conventional mechanical ventilation (CMV),high frequency oscillatory ventilation(HFOV) and partial liquid ventilation (PLV),on the changes of inflammatory factors and pulmonary surfactant associated protein A (SP-A) in bronchoalveolar lavage fluid (BALF) in newborn piglets with acute lung injury(ALI).Methods Twenty-four newborn piglets,no more than 3 days old,were enrolled.After ALI made with saline lavage(38 ℃,35 mL/kg),newborn piglets were randomly assigned to 4 groups:control group (n =6,no ventilation),CMV group(n =6),HFOV group(n =6),and PLV group(n =6).Piglets were sacrificed after being ventilated for 24 h.Tumor necrosis factor-α (TNF-α),interleukin-8 (IL-8),interleukin-1 (IL-1) and SP-A in BALF were measured quantitatively by using enzyme-linked immunosorbent assay.Results In 3 groups using different ventilation methods,the population mean of TNF-o,IL-8,IL-1 and SP-A were statistically different (all P =0.000).SP-A in PLV group and HFOV group were higher than that in CMV group (all P ＜ 0.05),while IL-8,IL-1 and TNF-α in PLV group were lower than those in CMV group (all P ＜ 0.05),IL-8 and TNF-α in PLV group were lower than those in HFOV group (all P ＜ 0.05),IL-8 and TNF-α in HFOV group were lower than those in CMV group (all P ＜ 0.05).Conclusions Pulmonary inflammatory reaction was different in 3 ventilation groups.Compared with CMV and HFOV,PLV attenuated inflammatory reaction,so it could increase the expression of SP-A and decrease the degradation of SP-A.

OBJECTIVE: To observe the changes of vasoactive substances in rabbits administered with mannitol at different dosages and to investigate the mechanism of acute renal failure (ARF) induced by massive mannitol administration. METHODS: Eighteen healthy male New Zealand rabbits were randomly divided into 3 groups: a minor mannitol group (n=6, mannitol 8 g/kg within 2 hours), a control group (n=6, saline of the same volume), and a massive mannitol group with free water taking (n=6, mannitol 40~60 g/kg within 3 days). The changes of renin, angiotensin-I (ang-I), angiotensin-II (ang-II), endothelin (ET), and atrial natriuretic factor(ANF) in the serum were observed. RESULTS: No significant changes in the renin, ang-I, ang-II, ET, and ANF in the serum were found between the minor mannitol group and the saline control group (P> 0.05). In the massive mannitol group with free water taking, renin, ang-I, and ang-II in the serum increased significantly compared with the other 2 groups; ET in the serum decreased significantly compared with the saline control group (P< 0.05); no significant changes in the ANF in the serum were found compared with the other 2 groups(P> 0.05). CONCLUSION ARF induced by massive mannitol administration is associated with a significant change of vasoactive substances.
