Conclusion All five compounds were isolated for the first time from BHT.

AIM　Here the development of a simple, rapid and simultaneous method for the separation of five ephedrine alkaloids obtained with non-aqueous capillary electrophoresis (NACE) were reported. The effects of the electrolyte, non-aqueous solvent on the separation were also discussed. METHODS　A running buffer of 50 mmol/L ammonium acetate in methanol was found to be the most suitable for this separation. RESULT　The best separation was achieved within 8 minutes. CONCLUSION　The separation is not only dependent on differences in the pK value of the alkaloids but also on the intramolecular interaction and solvation. So much improved selectivity could be achieved in nonaqueous medium.

Object To develop a rapid method for the determination of ephedrine alkaloids in Ephedra sinica Stapf by nonaqueous capillary electrophoresis (NACE) and evaluate the extracting method by determining the amount of alkaloids Methods The buffer contained 50 mmol/L ammonium acetate in methanol without any additives was used And the detection wavelength was 210 nm Results The best separation result was achieved within 8 min Linearity was obtained in range of 9 8-147 0 ?g/mL pseudoephedrine, 6 8-102 0 ?g/mL for norephedrin, 9 4-141 0 ?g/mL for ephedrine, 4 8-72 0 ?g/mL for norpseudoephdrine, 6 8-102 0 ?g/mL for methylephedrine respectively The recovery range of these five alkaloids was 95 0%-100 4% Conclusion This method is rapid and accurate for the quantitative analysis of ephedrin alkaloids in E sinica

Object To study the isomers of amygdalin in BUYANG HUANWU TANG and its production Methods Amygdalin was isolated from both peach seeds and BUYANG HUANWU TANG by using various column chromatography Their structures were identified by the various spectral data Results Amygdalin had been isolated from n BuOH fraction of aqueous extract of BUYANG HUANWU TANG and found to be a pair of D , L epimers and their ration was 1∶1 It was also found that the structures and the ration of D , L epimers of amygdalin in decoction of single peach seed were similar to that in BUYANG HUANWU TANG. The peach seed only gave D amygdalin when it was extracted in 95% EtOH at reflux temperature, and D amygdalin cannot be isomerized when it was treated in water at 100 ℃ Conclusion Isomerization of D amygdalin results from interaction between it and other compounds of peach seed in water at high temperature, and has no evident relation to other constituents in BUYANG HUANWU TANG L amygdalin is a new compound generated due to decoction of peach seed

OBJECTIVE: To investigate the perioperative treatments of endoscopic sinus surgery for nasal diseases in patients with coronary heart disease after PCI. METHOD: Clinical data of 12 cases of endoscopie-assised surgery such as nasal tumors resection,functional sinus surgery,correction of deviated nasal septum,low-temperature plasma hemostasis in patients with coronary heart disease after PCI were analyzed retrospectively. RESULT: Serious bleeding did not take place with the 12 cases during surgery, and surgery progressed smoothly; one of patients had heavy nosebleed after surgery, however her condition was stable when received active treatment. Follow-up 3 months to 2 years, nasal diseases of 12 patients recovered well and symptoms were relieved; cardiovascular events such as hemorrhage, thrombosis and so on did not occur. CONCLUSION Due to physiological function of the heart dysfunction in patients with coronary heart disease after PCI,they often accompany a number of trouble issues such as medical disorders, oral antiplatelet drugs, surgery affordability loss and increase surgical risk. Correct and effective perioperative treatments, strictly surgical indications are really necessary which can keep patients safe through perioperative period.

Objective: To study the chemical constituents of the stem bark of Albizia julibrissin Durazz. Methods: Chemical constituents were isolated by the repeated chromatography methods and their structures were identified by spectral analysis. Results: Five compounds were obtained as follows: 3 O [? D xylopyranosyl (1→2) ? D fucopyranosyl (1→6) ? D glucopyranosyl] 21 O (6S) 2 trans 2 hydroxy methyl 6 methyl 6 O ? D quinovopyranosyl 2,7 octadienoyl acacic acid 28 O ? D glucopyran osyl (1→3) [? L arabinofuranosyl (1→4)] ? L rhamnopyranosyl (1→2) ] ? D glucopyranosyl ester (1). acacigenin B (2), julibrotriterpenoidal lactone A (3), machaerinic acid lactone (4), acacic acid methylester (5).

Cerebral smal vessel disease (CSVD) can be divided into sporadic and hereditary CSVD. The exact pathogenesis of sporadic CSVD is unknow n. Genetic factors may also play an important role, except for environmental and vascular risk factors. As a complicated disease, sporadic CSVD has the characteristics of multigenetic susceptibility. Therefore, investigating the related genetic factors may contribute to understanding the pathogenesis of sporadic CSVD. This article review s the advances in research on the genetics of sporadic CSVD.

Objective To comprehend the awareness rate and the implementation of risk factors related to Helicobacter pylori (HP) infection in families with children of Helicobacter pylori infection.To analyze the existing problems and formulate effective methods of health education.Methods Totally 558 families infected with HP were investigated with a self-designed structured questionnaire by call-back.Results 527 did not use separate eating tools,350 did not use independent tablewares,14 drank unboiled water,14 did not use bath appliances separately,7 used tooth glasses together,4 did not wash hands before eating and after toilet,no one had mouth-to-mouth feeding.248 children with HP sleeped with their family members and 246 family members used to have HP infections or stomach troubles.Conclusions The families with HP do not establish correct ways of separate eating,so the hospital need to develop multi-channel education.Most families with HP infected children have satisfactory health habits.Nearly half of the children with HP do not sleep in their own beds.Caregivers of children with HP infection should be the capital objects of health education.
