Objective To determine the antioxidant activity of different polar fractions of Jasmine leaves.Methods The extract of jasmine flo wer leaves was extracted with petroleum ether,ethyl acetate and n-butanol to obtain the petroleum ether,ethyl acetate,n-butanol and water fractions.The scavenging abilities of different polar fractions of jasmine leaf on 1,1-two-2-three nitro phenyl hydrazine (DPPH) free radicals,ABTS + radicals,O2-radicals,OH-radicals and the reduction of Fe3 +,Fe2+ were investigated and were compared with that on 2,6-tert butyl -4-methyl phenol (BHT).Results All the fractions had the ability to scavenge DPPH free radicals and ABTS + radicals.The petroleum ether fracton had the strongest ability to scavenge oxygen anion radicals and the ability of different fractions to scavenge hydroxyl radicals was n-butanol ＞ ethyl acetate ＞ petroleum ether ＞ water.For the ability to restore Fe3 +,the most powerful was water reducing part,the weakest was the ethyl acetate part,for the ability of chelating Fe2+ ethyl acetate part was higher than BHT,and the n-butanol part was the weakest.Conclusion The different polar fractions of Guangxi Jasmine leaves had certain antioxidant activity.

Objective To investigate the metabolic effects of glucose dependent insulinotropic peptide receptor antagomst pro3 (GIP) in induced diabetes mice about blood glucose,triglyceride,cholesterol,leptin and fatty issue.Methods 27 C57 mice were randomly divided into normal group and diabetes mice group,and the mice in diabetes group were fed with high fat food and intraperitoneal injected streptozocin.Then 1 mouse that random blood giucose lower than 16.9 mmol/L was deleted in diabetes group.The rest mice in diabetes group were divided into two groups,diabetes control group,pro3 (GIP) group.Pro3 (GIP) group was given drug pro3 (GIP).The bloodglucose and glucose tolerance were measured.After treatment for 6 weeks,all mice were sacrificed and fatty tissues were collected.Results After 6 weeks,the blood glucose of the pro3 (GIP) group was obviously lower than diabetes control group (t=8.43,P＜0.01),and insulin levers in 0,30,60 and 120 min were obviously lower than diabetes control group (t =3.90,2.60,6.88 and 3.33,P＜0.05).There was significant difference between pro3 (GIP) group and diabetes control group about inflammatory cells.Moreover,leptin in pro3 (GIP) group was obviously lower than in diabetes control group (t =5.04,P＜0.01),but triglyceride,cholesterol,and adiponectin had no significant difference between two groups.Conclusion Pro3 (GIP) can significantly reduce blood glucose,insulin level,leptin of diabetes mice,and attenuate the inflammatory cells infiltration in fatty issue.

AIM To observe the changes of serum ROS,MDA,SOD levels in chronic renal failure (CRF) patients with damp-heat syndrome and to explore the intervention effect of Qingshen Granules (Hedyotis diffusae Herba,Salviae miltiorrhizae Radix et Rhizoma,Artemisiae scopariae Herba,etc.) on oxidative stress.METHODS Seventy cases of CRF patients with damp-heat syndrome were randomly and equally divided into control group and treatment group.Sixty cases completed the study,thirty-one cases in the treatment group,twenty-nine cases in the control group.Twenty other cases served as the normal group.The treatment group and the control group were given the basic treatment of western medicine and retention enema of TCM.The treatment group was added Qingshen Granules for eight weeks.The levels of U-Pro/24 h,Scr,BUN,estimated glomerular filtration rate (eGFR),serum ROS,MDA and SOD were measured before and after the treatment,and were compared with the normal group.RESULTS Both total effective rates on disease and on traditional Chinese medicine syndrome in the treatment group were 83.87％,significantly higher than those in the control group (51.72％ and 48.28％),respectively.The levels of U-Pro/24 h,Scr and BUN were obviously lower in the treatment group after the treatment,and eGFR was obviously higher as compared with those in the control group.Before the treatment,the levels of ROS and MDA in the treatment and control groups were significantly higher than those in the normal group,and the level of SOD was significantly lower;the levels of ROS and MDA were reduced in the treatment group after the treatment,and the level of SOD was increased;these changes in the treatment group were more significant than those in the control group.CONCLUSION Qingshen Granules can ameliorate clinical symptoms in CRF patients with damp-heat syndrome,decrease the levels of U-Pro/24 h,Scr and BUN,increase eGFR level,inhibit oxidative stress,and enhance antioxidant capacity,ultimately delay the development of renal fibrosis.

Objective:To analyze the incidence and mortality of thyroid cancer among permanent residents in Luwan district of Shanghai from January 2004 to December 2011.Methods:The data of thyroid cancer in permanent residents of Luwan district were collected from the database of cancer registration and management system in Shanghai.The incidence and mortality of thyroid cancer were calculated.The rates were standardized by the demographic composition developed in the Fifth Nationwide Census in the year 2000.The temporal trend in the incidence and mortality of thyroid cancer was assessed using average annual percent change.Results:A total of 413 cases of thyroid cancer were diagnosed from 2004 to 2011,accounting for 3.96％ of the total patients with malignant diseases.During 2004 to 2011,the crude incidence rates ranged from 7.49/105 to 34.86/105,and the standardized incidence rates ranged from 6.02/105 to 23.63/105,displaying a significant increasing trend.The incidence rate in females was significantly higher than that of males.The incidence rate of females peaked at 40-55 years of age.A total of 24 cases died of thyroid cancer during this period.During 2004 to 2011,the crude mortality rates ranged from 0.63/105 to 1.61/105,and the standardized mortality rates ranged from 0.13/105 to 0.46/105.The mortality rate remained stable during the eight year period.Conclusions:There were significant increases of thyroid cancer occurrence from 2004 to 2011 among permanent residents in Luwan district of Shanghai.The mortality rate of thyroid cancer is low.Both the incidence and mortality rates of females were significantly higher than those of males.It is important to identify risk factors of thyroid cancer,so effective control measures can be taken to control its rapid increase.

Objective To investigate the effect of cytochrome P450 2C19 (CYP2C19) gene polymorphism on the antiplatelet therapy of clopidogrel in patients who underwent percutaneous coronary intervention (PCI).Methods Fifty-five patients who underwent PCI,as well as twenty-three healthy subjects,were enrolled in this study.The genotypes of the samples were identified by gene chips hybridization.The contents of soluble P-selectin (CD62p) and platelet glycoprotein GP Ⅱ b/Ⅲ a fibrinogen receptor(PAC-1) in patients who underwent PCI were detected by flow cytometry (FCM).The expressions of platelet activation markers were calculated according to interquartile range method.Results Seven patients with CYP2C19 * 2/* 2 genotypes were poor metabolizers,while twenty-eight patients with CYP2C19 * 1/* 2,CYP2C19 * 1/ * 3 were intermediate metabolizers,twenty patients with CYP2C19 * 1/ * 1 were extensive metabolizers.In intermediate metabolism (* 1/* 2),intermediate metabolism (* 1/* 3) and poor metabolism group,the CD62p expressions were (6.73 ± 5.69) ％,(10.94 ± 9.80) ％,(14.35 ± 6.24) ％,(16.80 ± 13.65) ％,respectively,statistically significant differences were found when compared with the control group;The PAC-1 expressions were (1.06 ± 0.69) ％,(2.10 ± 4.09) ％,(2.37 ± 3.15) ％,(2.89 ± 2.75) ％,and there were significant differences in CD62p and PAC-1 among the groups(P ＜0.05).The genotypes of extensive metabolism was high in the response to clopidogrel,while those of intermediate metabolism were moderate and poor metabolism were low.Conclusion Intermediate metabolism genotype patients could be adjusted to the dose of clopidogrel or the use of other antiplatelet drugs,and the poor metabolism genotype patients should be used other antiplatelet drugs.
