ABSTRACT

In this experiment, ultra high performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was used to analyze and identify chemical constituents of Ginseng-Douchi(GD) compound fermentation, and explore the conversion rules of ginsenosides and soybean isoflavones after compound fermentation. Waters Acquity UPLC BEH C_(18) column(2.1 mm×100 mm, 1.7 μm) was adopted, with 0.1% formic acid aqueous solution(A)-0.1% formic acid acetonitrile solution(B) as mobile phase for gradient elution; electrospray ion source(ESI) was used to collect data in positive and negative ion modes; according to the exact mass number, the secondary spectrum comparison of the database and the existing literature reports, Peakview 2.0/masterview 1.0 software was used to determine the common ion structure formula. Finally, a total of 133 chemical constituents were analyzed and identified from the GD. Ginseng saponins and isoflavone glycosides were significantly converted after fermentation. Among them, peak areas of prototype ginsenosides Rk_3, Rh_1, Rh_2, Rh_3, daidzin, glycitin and genistin decreased significantly; whereas peak areas of se-condary ginsenoside Rb_1, Rb_2, Rk_1, glycitein, genistein and daidzein increased significantly. In this experiment, liquid-mass spectrometry technique was used to investigate the conversion of active ingredients of GD compound fermented products after co-fermentation, so as to provide a scientific basis for elucidating pharmacodynamics material basis and quality control.

ABSTRACT

Objective:To evaluate the regulation effect of corn silk on fatty acid compositions in adipose tissues of rats with type 2 diabetes mellitus(T2DM) based on gas chromatography-mass spectrometry (GC-MS), and explore the mechanism of corn silk water decoction for lipid metabolism disorder in . Method:Rat model of T2DM was established by high-sugar and high-fat diet combined with intraperitoneal injection of 35 mg·kg-1 streptozocin (STZ). They were randomly divided into model group,metformin group,and low,medium and high dose groups(5.4,10.8,21.6 g·kg-1) of corn silk decoction, with administration of 4 weeks. Serum was taken from the abdominal aorta for the determination of free fatty acids (FFAs),blood lipids [total cholesterol(TC),triglyceride(TG),high-density lipoprotein(HDL-C),low density lipoprotein(LDL-C)],and adipose tissue was taken for pathological section analysis. At the same time,GC-MS technology and multivariate statistical analysis methods were adopted to investigate the fatty acid compositions in adipose tissue. Result:After treatment with corn silk decoction,the contents of FFAs,TC,TG,HDLC and LDLC in T2DM rats were all reversed. As compared with the model group,the morphology of rat adipocytes,macrophage infiltration,vascular congestion and other phenomena were restored after administration. GC-MS analysis showed that the contents of palmitic acid and stearic acid in the adipose tissue of T2DM rats were significantly increased,while the contents of tetradecanoic acid,pentadecanoic acid,9-octadecenoic acid,9-hexadecenoic acid and 5,8,11,14-eicosatetraenoic acid were decreased significantly,and all the dose groups of corn silk had a reversing effect on differentially expressed fatty acids. Conclusion:Corn silk can be able to reverse the fatty acid content in adipose tissue and restore the morphology of adipose tissue,with a regulating effect on the lipid metabolism disorder in T2DM rats.

ABSTRACT

The chemical compositions of Anemone raddeana Rhizome, a kind of traditional Chinese medicine, were reviewed, along with its bioactivity and pharmacological properties and method improvements of extracting and detecting triterpenoid saponins. A. raddeana Rhizome is used to treat neuralgia and rheumatism, and is rich in triterpenoid saponins, most of which are pentacyclic, with oleanane as the nucleus. So far, 37 triterpenoid saponins have been determined from the herb. Its reported bioactivity and pharmacological properties have been described as anticancerous, antimicrobial, anti-inflammatory, analgesic, antipyretic, anticonvulsive, antihistaminic, and sedative. It has also been used for the induction of the humoral immune response and treatment of liver fibrosis in chronic hepatitis. However, the herb also has hemolytic effects and can be toxic, which limits its clinical application. Further studies are needed on the pharmaceutical functions, mechanisms, and immunological responses to contribute to the herb's clinical applications.

ABSTRACT

<p><b>OBJECTIVE</b>To study the effect of minimally invasive treatment with the locking compression plate (LCP) in the treatment of intertrochanteric fractures in the elderly age.</p><p><b>METHODS</b>Twenty-eight cases of intertrochanteric fracture were retrospective studied from August 2007 to January 2009, included 13 males and 15 females with an average age of 78.6 years ranging from 70 to 102 years. All the 28 patients were treated with minimally invasive operations with locking compression plates. The time from injury to operation was ranged from 3 to 8 days (with an average of 4.5 days).</p><p><b>RESULTS</b>The operation time was from 40 to 90 minutes (with an average of 55 minutes). The average bleeding volume during the operation was 70 ml (from 50 to 150 ml). One patient died during hospital stay. Twenty-five patients were followed up from 6 months to 2 years with an average of 15 months after operation. The fracture healing time was from 10 to 12 weeks (10.4 weeks in average). According to an evaluation standard of HUANG Gong-yi, the results were excellent in 20 cases,good in 4 cases, poor in 1 case.</p><p><b>CONCLUSION</b>Minimally invasive approaches with LCP could treat the elder intertrochanteric fractures with the advantages such as minimal invasive, stable fixation and less blood loss.</p>
