A simple, precise, and rapid high-performance liquid chromatographic method was developed and validated for the simultaneous determination of vitexin-2-O-glucoside, vitexin-2-O-rhamnoside, rutin, vitexin, and hyperoside. The HPLC separation was performed using a Shim-pack VP-ODS C18 column (250 mm × 4.6 mm i.d. , 5 μm) with the isocratic mobile phase consisting of tetrahydrofuran/acetonitrile/0.05％ phosphoric acid solution (20:3:77, v/v/v), and the flow rate was set at 1.0 mL/min. UV detection was carried out at a wavelength of 360 nm and the whole analysis took 25 min. The method was linear in the range of 4.12-206.00 μg/mL for vitexin-2-O-glucoside, 4.05-202.50 μg/mL for vitexin-2-O-rhamnoside, 1.64-82.00 μg/mL for rutin, 1.74-87.00 μg/mL for vitexin, and 1.41-70.60 μg/mL for hyperoside with the correlation coefficient for each analyte more than 0.998.The limit of detection (LOD) and limit of qnantitation (LOQ) were 0.6 and 2 ng for vitexin-2-O-glucoside, 0.6 and 2 ng for vitexin-2-O-rhamnoside, 0.3 and 1 ng for rutin, 1 and 3 ng for vitexin, and 0.5 and 2 ng for hyperoside, respectively. Lntra- and inter-day precision and accuracy (RSD) were less than 3％. The developed HPLC method was successfully applied to the analysis of five flavonoids in hawthorn leaves, hawthorn fruits, and the preparations containing hawthorn leaves or fruits.

Objective To study the anti-depressive mechanisms of acupuncture by investigating the effects of acupuncture on depressive behaviors and amino-neurotransmitter in hippocampus in rats treated with chronic mild unpredicted stresses.Methods Thirty adult SD rats were randomly divided into a normal group,a depressive model group and an acupuncture group,with 10 rats in each group.Separated feeding,long-term unpredictable and middle stimulation stress were used for development of depression rat model.At the same time,the third group was treated by acupuncture.Autonomic behavior was measured with Open Field test and concentration of amino-neurotransmitter in hippocampus was measured by high performance liquid chromatography coupled with fluorescence detection.Results Compared with the normal group,autonomic activity of the rats and the concentration of GABA were significantly reduced in the model group,while the concentration of Glu was significantly increased(P0.05).Conclusion Acupuncture could reverse the depressive behaviors of rats caused by middle stimulation stress,and its anti-depressive mechanisms is related to the function of regulating the concentration of amino-neurotransmitter in hippocampus.

Objective: To analyze the status and general trend of urban residents’ health equity and health performance. Methods:Adopting standardization of concentration index, the extended concentration index and health performance index. Results: Chronic disease and self-assessed health of urban residents in China gradually improved from 2007 to 2011, while disability of those people did not improve significantly. Health inequity exists among urban residents with different incomes. Chronic disease and disability are inclined to the poor while self-assessed health is inclined to the rich, but the unfair degree has decreased gradually by year; the self-assessed health and the health performance of chronic disease has been improved from the comprehensive health level and equity, the disability sustains serious condition. Conclusion: China’s new health care reform does not significantly improve the domestic urban residents’ health equity and health performance, the objective set of the health care reform in China should pay more attention to health equity.

Objective To investigate the predictive value of 4 183 Da peptide of dermcidin protein in the early diagnosis and differential diagnosis of ischemic heart disease.Methods A prospective controlled study was conducted.Serum samples were drawn from 161 patients with acute coronary syndrome [ACS,including 46 patients with unstable angina (UA),23 with acute non-ST elevation myocardial infarction,and 92 with acute ST segment elevation myocardial infarction],111 subjects for routine physical examination,including 45 patients with hypertension history,42 with coronary heart disease,22 with diabetes,and 54 patients with non-ACS (including pulmonary embolism,aortic dissection aneurysm,arrhythmia,myocarditis,coronary myocardial bridge,pleurisy,pneumothorax,pneumomediastinum,rib fracture,reflux esophagitis,peptic ulcer,and pancreatitis) to serve as controls.4 183 Da peptide of dermcidin protein was assessed with matrix assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS) technology,and myeloperoxidase [MPO,determined by point-of-care testing (POCT) and enzyme linked i mmunosorbent assay (ELISA),respectively],high sensitive C-reactive protein (hs-CRP),heart type fatty acid binding protein (H-FABP),myoglobin (MYO),cardiac troponin Ⅰ (cTnⅠ),and MB isoenzyme of creatine kinase (CK-MB) were quantitated with biochemical analysis.The power of the biomarkers above for early diagnosis and differential diagnosis for ischemic heart disease were judged by comparison of their sensitivity and specificity.Results ① It was showed by one-way ANOVA that 4 183 Da peptide was higher in ACS group than that in control group (relative abundance:22.05 ± 16.97 vs.15.52 ± 14.09,P =0.001),but no difference was found between ACS group and non-ACS group (relative abundance:22.05 ± 16.97 vs.19.99 ± 17.63,P =0.416).② The specificity and sensitivity of the 4 183 Da polypeptide and MPO for predicting ACS and UA were compared with the receiver operating characteristic curve (ROC).It was showed that the 4 183 Da polypeptide had predictive values for ACS and UA,and the areas under the ROC curve (AUC) was 0.625 and 0.651 (both P ＜ 0.01),but MPO was not found to have predictive value (AUC was 0.440 and 0.336,respectively,both P ＞ 0.05).③ It was showed by the values of multi-markers in differential diagnosis of ACS and non-ACS disease that the specificity and sensitivity of 4 183 Da peptide in the differential diagnosis of acute myocardial infarction (AMI) and non-ACS disease were less than those of MYO,cTnⅠ,H-FABP,markers of myocardial damage,which AUCs were 0.569 vs.0.796,0.833,0.838,and equal to MPO (POCT/ELISA) and hs-CRP,AUC of which was 0.569 vs.0.505 (POCT)/0.477 (ELISA) and 0.545.But both the value of 4 183 Da peptide and MYO,cTnⅠ,H-FABP in the differential diagnosis of UA and non-ACS disease was not found,where AUC was 0.456,0.525,0.658,0.568.Conclusion 4 183 Da polypeptide,a fragment of dermcidin protein,may have association with the onset of ischemic heart disease,and may be helpful in the early diagnosis of ACS.

Objective: To observe the difference in anti-inflammatory effect between living rhino horn and rhino horn by the method of comparative research to provide the experimental basis for the replacement of rhino horn by living rhino horn.Methods: The anti-inflammatory effects of living rhino horn and rhino horn were studied by the methods of paw edema in rats, cotton ball granuloma in mice, auricle swelling and peritoneal dye penetration.Results: Compared with that in the model control group, the foot metatarsus swelling degree at all time points in high (440 mg·kg-1) dose group and middle (220 mg·kg-1) dose group of living rhino horn and three doses groups of rhino horn showed statistical differences (P＜0.05 or P＜0.01).The high dose group (700 mg·kg-1) and middle dose group (350 mg·kg-1) of living rhino horn and rhino horn could significantly reduce the weight of cotton ball granuloma in mice (P＜0.05).Three doses groups (700, 350 and 175 mg·kg-1) of living rhino horn and rhino horn could significantly reduce auricle swelling in mice induced by xylene (P＜0.05 or P＜0.01).The absorbance of Evansan in the abdominal cavity in the middle dose group (350 mg·kg-1) of rhino horn and the high dose group (700 mg·kg-1) and middle (350 mg·kg-1) dose group of living rhino horn was significantly reduced (P＜0.05 or P＜0.01).There was no significant difference in the anti-inflammatory effect between living rhino horn and rhino horn at the same dose.Conclusion: Living rhino horn and rhino horn have a certain anti-inflammatory effect.The anti-inflammatory effect of living rhino horn is similar to those of the rhino horn, and living rhino horn can be used as a substitute of rhino horn.

A method was developed for purification of 20S proteasome (20S core particle, CP) by combining differential centrifugations with nondenaturing polyacrylamide gel electrophoresis (native-PAGE), irrespective of species origins of CPs. CP purified from human erythrocytes was subjected to proteomic analysis by two-dimensional gel electrophoresis (2-DE) and matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS), revealing 33 spots of subunit isoforms with different molecular weights and isoelectric points, more than 14 constituent subunits. Furthermore, other four CPs were purified from yeast, mouse liver, two pancreatic cancer cell lines SW1990 and PANC-1 using this method mentioned above, and subjected to proteasome heterogeneity analysis by native/SDS-PAGE (native/sodium dodecyl sulphate polyacrylamide gel electrophoresis), together with CP from erythrocytes. The method described acts as a rapid and effective tool for CP isolations, and the results obtained may be served as a footstone for the investigations of species-dependent proteasome heterogeneity.
