ABSTRACT

ObjectiveHigh performance liquid chromatography (HPLC) was used to establish the specific chromatograms of Aurantii Fructus from different origins, and the quality variability of Aurantii Fructus from Sichuan was analyzed and evaluated by combining entropy weighting method and grey correlation method. MethodHPLC was performed on an Agilent Eclipse Plus C18 column (4.6 mm×250 mm, 5 μm) with a gradient elution of methanol (A)-0.1% phosphoric acid aqueous solution as the mobile phase (0-12 min, 25%-33%A; 12-21 min, 33%-41%A; 21-30 min, 41%-42%A; 30-40 min, 42%-59%A; 40-53 min, 59%-72%A; 53-60 min, 72%A; 60-65 min, 72%-100%A; 65-70 min, 100%A; 70~71 min, 100%-25%A; 71-80 min, 25% A) at a flow rate of 1.0 mL·min-1, the injection volume was 10 μL and the detection wavelength was 330 nm. Fifty batches of Aurantii Fructus samples from different origins (Sichuan, Chongqing, Jiangxi and Hunan) were tested, and the similarity evaluation software is used to generate characteristic profiles and compare them with control profile for peak identification, and then to evaluate the similarity of the samples. IBM SPSS 19.0 and SIMCA 14.1 were used to perform multivariate statistical analysis on the results of the samples, and then the entropy weighting method and grey correlation were used to calculate the overall quality score of samples from Sichuan. ResultHPLC specific chromatogram of Aurantii Fructus was established, and 14 common peaks were identified as eriocitrin, neoeriocitrin, narirutin, naringin, hesperidin, neohesperidin, meranzin hydrate, poncirin, meranzin, marmin, nobiletin, 3,3′,4′,5,6,7,8-heptamethoxyflavone, tangeretin and auraptene. And the similarities between the samples from Sichuan and the control chromatogram were all above 0.980. The samples could be classified into four categories according to their main origins by chemical pattern recognition, and the results of cluster analysis, principal component analysis and orthogonal partial least squares-discriminant analysis were all able to discriminate the samples of different main origins effectively. The comprehensive evaluation results of entropy weighting method combined with grey correlation showed that the quality of Aurantii Fructus from Sichuan varied greatly among different origins, and the quality of Aurantii Fructus from Sichuan was ranked as Bazhong>Luzhou>Chongqing>Neijiang. ConclusionIn this study, the characteristic mapping of Aurantii Fructus from Sichuan is established, and combined with the analytical methods of chemometrics and grey correlation, the quality of samples from different origins can be effectively differentiated, which can provide a reference for the comprehensive evaluation and control of the quality of Aurantii Fructus from Sichuan.

ABSTRACT

The hallmark lesions of age-related macular degeneration (AMD) are drusen and basal linear deposit which are lipid substances deposited in Bruch membrane or the compartment on the Bruch membrane.There is a prevailing hypothesis that lipid and its oxidized derivant deposited in retina may have important roles in the pathogenesis of AMD.Lipid oxidation products are toxic,may affect the adjacent cells,induce inflammation,and trigger neovascularization.7-ketocholestoral (7KCh),a naturally occurring oxidized form of cholesterol,had been found to be toxic to retinal cells and able to induce chronic inflammation,which may play a critical role in the development of AMD.However the precise mechanism remains to be elucidated.Thus we will make a brief review of 7KCh and its association with AMD.

ABSTRACT

Clinical evidences of acupuncture and moxibustion for sudden hearing loss(SHL) were completely collected, and the quality of the evidences was evaluated by Jadad scale. Cumulative Meta-analysis and the time tendency test for the results were implemented by STATA 12.0. Descriptive and academic cross-sectional investigation was carried out among senior professional doctors with acupuncture and moxibustion background in 31 provin-ces of China, and the advices of specialists were analyzed by fussy comprehensive evaluation. Thirty-eight researches were included. Cumulative Meta-analysis indicated that acupuncture and moxibustion combined with medication achieved better cured and total effects compared with multiple medicines[RR=1.57, 95%CI(1.38,1.79); RR=1.34, 95%CI(1.28,1.81)], and the efficacy had no time variability. The cured and total effects of acupuncture and moxibustion were superior to those of multiple medicines, but the results needed to be further verified. Five hundred and sixty-one questionnaires were put out in the 31 provinces, and 93.40% of ones were collected and eligible. Fuzzy comprehensive evaluation showed a tendency to overall improvement by acupuncture and moxibustion as the main intervention in the specialists' advice. Cumulative Meta-analysis and fussy comprehensive evaluation are applicable to estimate the effect and intervention level of acupuncture and moxibustion with low quality evidence.

ABSTRACT

Background The potential protective effect of ischemia postconditiomng for hypoxia has been determined in many tissues and organs.But its mechanism in retina is still lack.Objective The aim of this study was to investigate the protective effect of ischemia postconditioning on retinal ischemia reperfusion injury.Methods Thirty-six health male Wistar rats were randomized into the normal control group,sham group,ischemia reperfusion group and ischemic postconditioning group.Retinal ischemia reperfusion models were induced by elevating the intraocular pressure to 110 mmHg for 60 minutes,and then the ischemic postconditioning was performed right away,1 minute and 10 minutes after ischemia in the rats of the ischemic postconditioning Ⅰ,Ⅱ,Ⅲ group,respectively.Electroretinogram (ERG) was recorded in the rats 7 days after operation,and the rats were sacrificed by excessive anesthesia.Retinal specimens were prepared for the histopathological examination.The retinal thickness and the recovery rates of ERG a,b waves and oscillation potentials (OPs) were compared among the groups using ANOVA of SPSS software.Results One day after experiment,the structure of rat retinas was nearly normal.However,retinal edema and vacuolar degeneration were seen in the rats of the ischemia reperfusion group and ischemic postconditioning Ⅰ,Ⅱ,Ⅲ groups primarily in the inner plexiform layer (IPL),inner nuclear layer (INL).The retinal thickness values of the entire layer,IPL and INL were significantly higher in the ischemia reperfusion group and ischemic postconditioning Ⅰ,Ⅱ,Ⅲ groups compared with the normal control group (all at P<0.05).Seven days after experiment,the retinas were thinner in the rats of the ischemia reperfusion group than those of the rats in the sham group,but the retinal thickness values in the ischemic postconditioning Ⅰ,Ⅱ,Ⅲ groups were significantly increased in comparison with the ischemia reperfusion group (all at P<0.05).In addition,the recovery rates of ERG a,b,OPs amplitudes were significantly lower in the ischemia reperfusion group and ischemic postconditioning Ⅰ,Ⅱ,Ⅲ groups compared with the normal control group (all at P<0.05).However,the recovery rates of ERG a,b,OPs amplitudes evidently elevated in the ischemic postconditioning Ⅰ,Ⅱ,Ⅲ groups in comparison with the ischemia reperfusion group (all at P<0.05).Conclusions Ischemia postconditioning can protect the structure and function of retina from ischemia reperfusion injury.Ischemia postconditioning plays the maximal effect immediately to 1 minute after ischemia reperfusion injury in Wistar rat.

ABSTRACT

Objective To explore the effects of estrogen and angiotensin Ⅱ receptor 1 inhibitor(saralasin)on cell proliferation,cell cycle and apoptosis in endometrial carcinoma cell line HEC-1A.Methods Immunocytochemical assay was applied to detect the expression of AT1-R,PI3K,p-Akt and ERK protein in HEC-1A cell.The effects of estrogen and saralasin on cell proliferation,cell cycle distribution and apoptosis of HEC-1A cell were detected by MTT assay and fluorescence activated cell sorting technique.The expression of ERK and p-Akt protein in HEC-1A cell treated with estrogen and saralasin were analyzed by Western blot.Results The expression of AT1-R,PI3K,pAkt,and ERK protein was found in HEC-1A cell.Estrogen stimulated the proliferation of HEC-1A cell,decreased G0~G1 phase proportion and increased S phase proportion significantly,minimized the number of apoptotic cells,and up-regulated the expression of ERK protein.Saralasin obviously inhibited the proliferation and induced apoptosis of estrogen induced HEC-1A cell,increased G0~G1 phase proportion and decreased S phase proportion,and down-regulated the expression of ERK protein.Conclusion Estrogen could promote the proliferation of HEC-1A cell through AT1-R.AT1-R inhibitor saralasin could inhibit the proliferation and induce the apoptosis of estrogen induced HEC-1A cell.The down-regulation of ERK protein expression by interrupting the mitogen-activated protein kinase(MAPK)signaling pathway might be involved in the possible mechanism.Thus saralasin could be a valid approach to treat ER-negative endometrial carcinoma.
