Objective To study the effects of allopurinol in different dose on the cardiac function of chronic heart failure rats induced by adrimycin. To explore dose-dependency of allopurinol in improving blood vessel endothe-lium function and cardiac ventricle remodeling of the rats heart, as to supply evidence and new sight in clinical treat-ment of congestive heart failure. Methods 40 Sprague-Dawley male rats were randomly divided into four groups: normal control group (group A)、model control group (group B)、low-dose allopurinol group (group C)、high-dose allopurinol group (group D). The heart failure model was made by administering adriamycin to rats. After the model myocardial pathological changes were detected. Results Compared with the normal control group, the weight and heart weight of rats in model control group and allopurinol groups were obviously lessen (group A=(300.10± 9.85)g,group B=(200.67±9.91)g, group C=(233.14±9.42)g,group D=(248.25±13.34) g;group A= (828.30±50.97) nag, group B=(681.50±16.97) mg, group C=(743.00±17.20) nag, group D=(784.88± 36.83) mg,P<0.05). Heart weight indexes were all incerased ( group A=(2.76±0.15) mg/g, group B=(3.41± 0.17) mg/g, group C=(3.26±0.76) mg/g, group D=(3.11±0.65) mg/g, P<0.05). The hemedynamics resuh showed that myocardial contractile force were enhanced in drug groups. The level of NO, SOD were increased in the allopurinol groups compared with the model control group (group B: NO=(41.55±6.28) μmol/L, group C: NO= (52.47±5.59) μmoL/L,group D:NO=(61.04±4.26) μmoL/L; group B:SOD=(63.83±6.40) U/ml,group C: SOD=(76.29±7.99) U/ml, group D: SOD=(100.13±7.43) U/ml, P<0.05) and MDA levels were obviously decreased (group B: MDA=(9.70±1.08) μmol/L, group C: MDA=(6.64±0.34) μmol/L, group D: MDA= (5.72±0.71)p.moVL,P<0.05). The level of NO, SOD were obviously increased in the allopurinol of high-dose group compared with low-dose allopurinol group(P<0.05). MDA levels were obviously decreased(P<0.05). The myocardial pathological changes were relieved obviously in the allopufinol groups. Conclusion Allopurinol improves blood vessel endothelium function dose-dependently. High-dese allopurinol obviously decreases MDA, improve NO, SOD, thereby can improve the cardiac function of heart failure.

OBJECTIVETo study the effect of some active Chinese herbal fraction on protein expression of brain tissue in ischemic mouse with proteomic technique.

METHODSIschemia-reperfusion mice were treated with baicalin, geniposide, cholic acid and concha margaritifera respectively for 3 hrs, and then their brain tissue were taken to extract the total protein. Protein expression in ischemic mouse brain was analyzed with surface-enhanced laser desorption/inionation-time of flight-mass spectra (SELDI-TOF-MS) protein-chip.

RESULTSThe four components tested had effect on 3 target proteins at 5373Da, 5707Da and 15103Da, showing the nature of multi-target and with different action on protein expression.

CONCLUSIONProtein-chip is an effective approach for exploring the pharmacological mechanism of Chinese herbal fraction.

Objective:To investigate the brain activation patten associated with visual sexual stimuli.Method:Thirteen healthy right-handed women were enrolled through advertisements on campus.They were scanned under functional magnetic resonance imaging(fMRI) when they watched emotional neutral films excepts and erotic films excepts.Statistic on theses data reveals the difference of brain activation.Result:The results showed that,compared to emotional neutral films,sexual visual stimuli were associated with the activation of a set of bilateral brain areas including lateral occipital cortex,postcentral gyrus,superior parietal lobule,occipital fusiform gyrus, hippocampus,and so on.Most activated brain areas are bilateral.Only in inferior frontal gyrus pars opercularis(Z=3.64,P<0.0001) and pars triangular(Z=3.42,P=0.003) there were significant right hemispheric activation.Conclusion:fMRI results indicate that inferior frontal gyrus is related to the visual sexual stimuli of women subjects,and is specified on the right hemisphere rather than left one.This sphere-special area may play an important role on sexual message processing.

Objective To investigate the relationship between infarct location and prognosis after emergency percutaneous coronary intervention (PCI) treatment in patients with acute myocardial infarction.Methods Consecutive 121 patients with ST elevation myocardial infarction (STEMI) who underwent primary PCI were divided into 3 groups according to the infarct location.Their clinical,ECG,echocardiography and coronary angiography features were analyzed,and the follow-up was made. Results Compared with inferior wall infarction group and inferior wall infarction combined with right ventricular infarction group,anterior wall myocardial infarction group had higher CPK-MB and cTnT,less frequent collateral,reduced ST-segment resolution,higher mortality rates in hospitalization and one year after discharge.On the other hand,inferior infarction combined with right ventricular infarction group had more occurrences of shock and atrial vetricular block or ventricular arrhythmia,more incidence of multivessel disease and thrombus,and higher readmission rate.Conclusion Patients with anterior wall myocardial infarction and inferior wall in

Background and purpose:Pain is one of the most common symptoms in advanced cancer patients, and morphine is a representative drug in controlling moderate to severe cancer-induced pain, but some unacceptable adverse effects limited its use in part of patients.We evaluated the effect and safety of morphine sulfate controlled-release tablet (MS-CRT) combined with celecoxib for the treatment of moderate to severe cancer pain, and assessed the life quality of patients. Methods:Retrospective analysis of 125 cancer patients with moderate to severe cancer pain who were divided into two groups, one(including 67 patients) was treated by single drug of MSCRT whose initial dosage was 20 mg/12 hrs, then evaluated by verbal rating scale within 24 to 48 hrs, dosage was adjusted personally according to the state of pain (increasing rate was 50% and declining rate was 25%) until the maintenance dosage was reached; the other(including 58 patients) was treated by MS-CRT with the same initial dosage and combined with celecoxib whose dosage was 200 mg/12 hrs at first, and increased to 400 mg/12 hrs if the pain was not relieved well, then gradually increased the dosage of MS-CRT to the maintenance dosage, and analyzed the effect, dose adjustment,side effect of drug combination and improvement of quality of life for the patients. Results:The mean of maintenance dosage for MS-CRT alone was 67.3 mg/day, and for the combination of MS-CRT and celecoxib was 51.3 mg/day, the reduction rate of MS-CRT in the drug combination group compared with MS-CRT alone was 23.77% with the same analgesia effect, and the incidence of side effects such as constipation and nausea/vomiting was statistically reduced compared with the single drug group. The quality of life in both groups was improved aftertreatment. Conclusion:The combination of MS-CRT and celecoxib can effectively control moderate to severe cancer pain, , improve the quality of life in advanced cancer patients, and reduce the consumption of MS-CRT with similar side effects as morphine alone.

Objective To investigate the molecular mechanism of Loureirin A mediated anti-hepatic fibrosis by evaluting its effects on proliferation , secretion ofα-smooth muscle actin (α-SMA) and transforming growth factor-beta1 (TGF-β1), and expression of rat hepatic stellate cells in vitro . Methods Primary hepatic stellate cells were isolated and cultured from Sprague-Dawley rats. After activating and inducing primary hepatic stellate cells from qHSC to aHSC, the activated hepatic stellate cells model in vitro was established. Then we observed the morphological changes of static hepatic stellate cells and activated hepatic stellate cells with inverted phase contrast microscope. Cultured hepatic stellate cells were treated with different concentrations of loureirin A and the inhibitory rate of HSCs proliferation was measured by MTT assay. The expression of Frizzled-4 was measured by western blot analysis. The content ofα-SMA and TGF-β1 in the cultured HSCs'supernatant were measured by enzyme-linked immunosorbent assay (ELISA) . Results Loureirin A the proliferation of inhibited activated hepatic stellate cells in a time-dose-dependent manner compared with the control group,IC50=0.30 μg/μL. After loureirinA treatment of the HSCs, western blot analysis showed that Frizzled-4 expression level was obviously lower than control group. Loureirin A also inhibitedα-SMA and TGFβ1 (P<0.05) secretion in the cultured HSCs'supernatant in different degree by the assay of ELISA. Conclusions The molecular mechanism of Loureirin A and Wnt signaling pathway mediated anti-hepatic fibrosis and anti-angiogenesis may involve down-regulation the expression of Frizzled-4, inhibiting the synthesis and secretion ofα-SMA,TGF-β1and the proliferation of HSCs.

Atopic dermatitis (AD) is an inflammatory skin disease closely related to impairment of skin barrier function.Hereditary factors,life style and exposure to the environment all contribute to the occurrence of AD.Even though AD occurs mostly in infants,sometimes it may initially occur in adults,which is called adult-onset AD (AOAD).There are evident differences in types,immunological mechanisms and association with other diseases between childhood AD and AOAD.The lesional distribution of AOAD is similar to that of childhood AD,while AOAD is characterized by subacute and chronic dermatitis,and mainly manifests as dry hypertrophic lesions rarely complicated with exudation.Th1/Th2 imbalance and hyperfunction of antigen-presenting cells are immunological basis of AD occurrence.Moreover,FLG gene mutations are associated with the occurrence of AD.Acquired expression defect in the FLG gene induced by elevated levels of interleukin-13 (IL-13) only occurs in adults,suggesting that AOAD is different from AD that initially occurs during infancy and continues into adulthood.Infection,changes of bacterial flora in the skin and intestinal tract,and smoking are all important causative factors of AOAD,thus enquiries about histories of related diseases and smoking are helpful for the diagnosis of AOAD.

Objective To research the relationship between quality of life among the elderly with chronic periodontitis (CP) and the severity of CP.Methods A total of 471 elderly patients seeking treatment in the affiliated Stomatology Hospital of Kunming Medical University from September 2013 to January 2014 and their companions were investigated using the questionnaire according to the Chinese version of the Oral health Impact Profile-14.Those who diagnosed with CP were separated into two groups according to Community periodontal index (CPI) through periodontal examination.Group A was diagnosed with the early CP,and Group B was diagnosed with the late CP.Database was established by Epidata and statistical analysis was performed by SPSS.Results A total of 237 elderly patients with early CP and 139 with late CP were recorded.The mean OHIP-14 scores of the former were 14.36 ± 6.67,and the score of the later were 15.65 ± 7.12 relatively.The two groups who lived through negative effects were compared.The results suggested in the 14 items of OHIP-14.The statistical significance existed in the following 4 items,obvious pain appeared,uncomfortable when eating anything,unsatisfied with own diet,become easy to lose one's temper to others (P＜0.05).Conclusion OHR-QOL of elderly patients with the late CP is lower than that of those with the early CP.
