Aims To establish a UPLC-MS/MS meth-od for the determination of plasma concentration of scutellarein and its metabolite and to study their phar-macokinetics in rat plasma. Methods The analysis was achieved by BEH C18 column with a mobile phase composed of 0 . 1 % formic acid in acetonitrile and 0 . 1% aqueous formic acid using step gradient elution. A TQD tandem mass spectrometry equipped with electros-pray ionization source was used as detector and opera-ted by multiple reaction monitoring( MRM) positive ion mode. After intravenous injection of scutellarein, the concentrations of scutellarein and its major metabolite glucuronide scutellarin in rat plasma were determined at different time points. The pharmacokinetic parame-ters were calculated by DAS 2. 0 software. Results Good linearity was achieved for scutellarein, the ex-traction recovery was between 80 . 5 % to 90 . 5 %, the precisions and accuracy were good. The result showed the pharmacokinetic profiles of scutellarein and glucu-ronide scutellarin both fit to the two-compartment mod-el. Conclusion The above mentioned method is spe-cific, rapid, sensitive and suitable for the pharmacoki-netic studies of scutellarein and its metabolite.

Objective To explore the efficacy and safety of metformin therapy on obese nondiabetic children with hyperinsulinemia.Methods Twenty-two obese nondiabetic children with hyperinsulinemia were divided into two groups:control group(dietary counseling and exercise) and treatment group(dietary counseling and exercise combined with metformin).The changes of body mass index(BMI),fasting glucose(FPG),fasting insulin(FINS),insulin resistance(HOMA-IR),2 h PG,2 h INS,total cholesterol(TC) and triglyceride(TG),before and after treatment were determined,and the findings were compared and analyzed.Results After treatment,there were significant differences in BMI,TC,FINS,HOMA-IR levels(P0.05),except the BMI(P

To observe the regulative effect of applying garlic cream on acupoint Shenque (CV8) on circadian rhythm disorder induced by sleep deprivation.Methods:Twenty healthy adult men were randomly divided into normal group(group A),sleep deprivation group (group B) and treatment group (group C).Subjects in group B and C received 48-hour sleep deprivation,and in the meantime subjects in group C were treated by applying garlic cream on acupoint Shenque(CV8),while subjects in group A received no any treatment,then contents of serum noradrenaline (NA) and 5-hydroxytryptamine (5-HT) were detected.Results:The contents of NA in three groups all appeared typical circadian rhythm(P＜0.01 when group A is compared with group C,and P＜0.05 when group A is compared with group B).The peak value in group A was 158.377 and appeared at 10:56,peak value in group B was 291.529 and appeared at 19:44,peak value in group C was 255.964 and appeared at 17:06.The peak phase in group B shifted more obviously when compared with group A,and the peak phase in group C recovered slightly when compared with group B.The contents of 5-HT in group A showed typical circadian rhythm (P＜0.01) and the circadian rhythms in group B and C disappeared (P＞0.05).the peak value in group A was 196.563 and appeared at about13:10.Conclusion:The application of garlic cream on acupoint Shenque (CV8) Can adjust the disturbed circadian rhythm and accelerate the recovery of circadian rhythm.It is a simple and effective therapeutic method for adjusting circadian rhythm disorder.

Objective To investigate the application valve of bFGF to improve the viability of trans-plantation flap in Wistar rat. Methods Forty-eight Wistar rats were randomly divided into two groups based on the age: group A,B(1.5 month old, every group was 12 rats) and group C,D (3 month old, every group was 12 rats). After an ischemic model completed, recombinant bovine basic fibroblast growth factor (rb-bFGF) was given to groups A and C in ischemie zone by vascularization flap injection and the equality of normal saline to groups B and D. 14 days postoperatively, the muscular tissue was sent for histology, the blood vessel density was calculated by image analysis, and positive VEGF was detected by immunohistochem-istry. Results The member of capillaries and positive VEGF were more in group A than that in B, and also were morein group C than D(P < 0.05), but there were not statistic difference between group A and C (P > 0.05). Conclusion Recombinant bovine bFGF can stimulate angiogenesis and improve the ischemie vascu-larization flap of rat, which is not associated with their age.

Conclusion It is important to strengthen and develop ideological and political education among students in the university.And attention should be paid to the innovation and efficiency of the education.

Background With the changes of diet and living style,the diabetes has become the major diseases affecting human health.Diabetic cataract is a common complication of diabetes. Objective The present study was to investigate the difference of lens proteomics between diabetic cataract and age related cataract using two dimensional electrophoresis (2-DE) and mass spectrometry in order to postpone happening of diabetic cataract and offer the effective approach to the prevention and therapy of diabetic cataract. Methods The lenses were obtained from 8 diabetic patients and 12 age-related cataract patients during the surgery to extract the protein by lysis and centrifugation.The lens proteins were separated using immobilized pH gradients 2-DE.Image analysis was carried out using PDQuest Advanced-8.0.1 software package.Significant difference of the crystallines was identified by matrixassisted laser adsorption/ionization time of-flight-mass spectrometry (MALDI-TOF-MS) and peptide mass fingerprint combined with protein database. Results The maps of 2-DE showed that lens proteins of diabetic cataract and age related cataract were in the section of pH 5-9 with the relative molecular weight 14000-97000;while relative molecular weight of more abundant crystalline was localized at 20000-31000.About 3 differential protein spots were detected by image analysis software.Two crystallines,αB and βB1 crystallin,were identified using MALDI-TOF-MS.Conclusions Proteomic analysis of lens can be accomplished and the proteins can be well separated,moreover,differential proteins can be analyzed using 2-DE and mass spectrometry between diabetic cataract and age related cataract.These results indicate that αB and βB1 crystallin proteins accelerate the development of diabetic cataract.This technique offers a new avenue for clarity of lens proteins of diabetic cataract other than age related cataract.
