Objective To investigate the approach of diagnosis and therapy of particular tracheal bronchus foreign body.Methods The clinical materials of 26 cases cured in our department were analyzed retrospectively.Results All foreign bodies of cases were taken out successfully.Among them,the foreign bodies of 18 cases were removed from glottis;the foreign bodies of 4 cases were pulled out via laryngoscope;the foreign bodies of 3 cases were drawn away through tracheotomy by endoscopy and 1 case was moved out by bronchofibroscopy.Only 1 case had lung edema and then was cured by proper treatment.Conclusion Considering that the particular foreign bodies in tracheal bronchus are complicated sometimes,the diagnosis and therapy should be treated appropriately according to different situation.Furthermore,properly choosing surgical appliances and the approaches of anaesthesia and surgery is also critical.

Aim To research the protective effects of specnuezhenide, an active compound of traditional Chinese medicine, against CCl4-induced hepatic dam-age in mice. Methods The model of acute hepatic damage caused by CCl4 intraperitoneal injection on mice was obtained. The levels of ALT, AST, TNF-α, IL-1β, and IL-6 in serum, the activities of MDA, SOD, and GSH-Px in liver homogenates, and the his-topathological organization of liver sections were also examined to observe the protective effects of specnu-ezhenide. Results Specnuezhenide markedly de-creased the CCl4-induced elevation of serum ALT and AST activities, and improved hepatic histopathology changes. Specnuezhenide also significantly decreased the content of MDA in liver tissues, meanwhile in-creased the activities of antioxidant enzymes SOD and GSH-Px. In addition, specnuezhenide reduced the lev-els of TNF-α, IL-1β and IL-6 . Conclusions Specnu-ezhenide has significant protective effects against CCl4-induced hepatic damage in mice, and the possible un-derlying mechanisms of the activity could be due to its antioxidant and anti-inflammatory effects.

Aim: To establish the metabolic fingerprint and profile of bioactive components in human plasma after sublingual administration of compound Danshen dripping pills. Methods: Human plasma samples were collected at different time intervals. Powerlab tension system was used to measure their ability of expanding blood vessel and column switching system was employed to purify and enrich the components of interest. Results: The plasma sample of 1.5h had the strongest ability for expanding blood vessel, and had five new peaks in the chromatogram. Conclusion: After being identified, the intensity ratio of these 5 peaks was calculated. The diagram called metabolic profile was established to link bioactive compounds with pharmacodynamic action.

OBJECTIVETo investigate the influence of Shi herb (Santalum album, SA) to the tissue distribution of danshensu (DSS) which is the main hydrosoluble component of Jun herb (Salvia miltiorrhiza, SM) in rabbits by HPLC.

METHODRabbits were oral administrated decoction of SM and SM-SA, respectively. Perchloric acid (10%) was used to precipitate the tissue samples of rabbits heart, brain, liver, kidney, acetic ether was used to extracte supernatant, and the internal standard was p-hydroxybenzoic acid. The content of DSS of SM in tissues was detected.

RESULTThe content of DSS reached the highest point close to 50 min in the mentioned tissues. Before and after co-administration, the sequences of average concentration of DSS in tissues were C(kidney) > C(heart) > C(brain) > C(liver) and C(kidney) > C(liver) > C(brain) > C(heart) respectively. Compared with SM administrated singly, the content of DSS in every tissues of co-administration was higher.

CONCLUSIONIn Danshenyin Formulae, SA can increase concentration of DSS in target tissues significantly, and therefore therapeutic effect of SM for cardiovascular disease is raised.

Erzhiwan includes two components of Chinese herbal medicines - Ligustri Lucidi Fructus and Herba Eclip-tae .Ligustri Lucidi Fructus ,Herba Ecliptae and their formulation have various hepatoprotective effects .There are many ac-tive ingredients in the formulation ,such as triterpenes ,iridoids ,phenethyl alcohol-glucosides ,coumarin ethers ,etc .They can resist various chemistry-induced hepatic injury ,ischemia reperfusion induced hepatic injury ,and hepatic fibrosis .The mecha-nisms of hepatoprotective effect include anti-oxidative stress ,anti-inflammatory ,inhibition of hyperplasia and activation of liver stellate cell ,motivating the apoptosis of liver stellate cell ,influencing the metabolic processes of liver cell ,ect .We reviewed and summarized the hepatoprotective effects of Erzhiwan and its components Ligustri Lucidi Fructus and Herba Ecliptae and explore the mechanisms of hepatoprotective effect in order to provide information for further research of pharmacodynamic ma-terial base .

OBJECTIVETo analyze the correlation between environmental factors and the lipophilic and hydrophilic constituents of Polygalae Radix.

METHODThe contents of lipophilic constituent were determined by GC-MS and hydrophilic constituents by HPLC. Geographical factors were collected by on-site inspection and climate factors by the local meteorological data. The relationship between the content of the lipophilic and hydrophilic constituents and the factors were analyzed by SPSS 18.0.

RESULTThere was linear relationship between the content of lipophilic constituent and climate factors such as average temperature of July, average temperature of January. There was also linear relationship between hydrophilic constituents and climate factors such as annual average temperature, latitude, annual average rainfall.

CONCLUSIONThe main climate factors that affect liposoluble constituent content were average temperature of July, average temperature of January, and the main climate factors that affect hydrophilic constituent content were annual average temperature, latitude, annual average rainfall. The study would contribute to the quality evaluation and suitability of origin of Polygalae Radix.

Stratospheric ozone depletion results in an increased level of solar UV-B radiation (UV-B, 280-320 nm) reaching the earth surface. By the effect of UV-B radiation, various medicinal active ingredients changed because of the change of gene expression, enzyme activity and secondary metabolism, clinical effect is also changed. The research status of UV-B radiation and the accumulation of plant secondary metabolites in the past 10 years were summarized in this paper to supply reference for cultivation and exploitation of the medicinal plants.

OBJECTIVETo study the influence of processing on metabolism of the main component of bitter almond-amygdalin in rat.

METHODThe blood was collected at different times after amygdalin given by injection and oral, bitter almond and its processed production given by oral respectively, and then detected by both HPLC and HPLC-MS(n) methods after extraction pretreatment.

RESULTAfter injection, amygdalin was absorbed in prototype to blood rapidly, while the other three kinds of medicine given by oral were all not detected the prototype of amygdalin, but two metabolites were detected which were isomers of prunasin confirmed by mass spectrometry. The metabolic pathway of prunasin in processed bitter almond group was markedly different from the bitter almond group.

CONCLUSIONProcessing has a significant effect on bitter almond metabolic processes in rats.

OBJECTIVETo research the germplasm resources and the contents of senegenin in processing products of Polygala tenuifolia.

METHODThe contents of senegenin in wild Polygala tenuifolia and cultivated samples of Polygala tenuifolia were determined by RP-HPLC, and compared.

RESULTThe contents of senegenin in wild reduce gradually along Shaanxi, Shanxi, Hebei to Dongbei. The contents of senegenin in cultivated three-year samples of three year Polygala tenuifolia from five main place was similar, 0.44%-0.49%. The content of senegenin were 0.44%-0.64% in the wand and 0.03%-0.09% in the residual part of stem, and the content of senegenin in Polygala tenuifolia was more than that in processing products.

CONCLUSIONThere is a correlation between the content of senegenin in Polygala tenuifolia and ecology environment that show a is inverse proportion with the quality grade, and the contents in the processing products were decreased. Senegenin can be used as a characteristic marker in range. This research provides a reference for search a index for quality control of Radix polygala and its processing products.
