Inflammatory response clearly occured in pathologically vulnerable regions of the Alzheimers disease (AD) brain. Many proinflammatory mediators, such as IL-1, IL-6,TNF-? and TGF-?, were significantly up-regulated in the pathophysiological process of AD. In addition to their traditional actions as proinflammatory molecules, AD-specific interactions of the cytokines and amyloid ?(A?) may be pathophysiologically relevant, and there was a reciprocal relationship within the cytokines inducing and being induced by A?.

Objective To evaluate the usefulness of contrast enhanced ultrasound in the diagnosis of breast lesions. Methods Contrast enhanced ultrasound was performed after administration of SonoVue in 104 patients scheduled for surgical tumor removal. The enhancement morphology was classified as non, peripheral,homogeneous,regional,or heterogeneous enhancement based on distribution of enhancing areas. All breast lesions enhancement morphology were analyzed, and the diagnostic value of contrast enhanced ultrasound was calculated. Results The prevalence of non enhancement was significantly higher in benign lesions than in malignant ones(P = 0.013),and the prevalence of peripheral enhancement was significantly higher in malignant lesions than in benign ones (P = 6.02 × 10-7). Conclusions Contrast enhanced ultrasound is useful in diagnosis of breast lesions.

Curcumin is the main active component in turmeric, which possesses many pharmacologic effects, including anti-in-flammatory, antioxidant, anti-tumor, anti-atherosclerosis, liver and kidney protection and so on. However, due to its poor bioavail-ability, its clinical application is limited. Therefore, the methods for improving the bioavailability of curcumin were reviewed by refer-ring to a large number of literatures. The bioavailability of curcumin can be improved by different administration routes and various dos-age forms. The review provides theoretical basis and research ideas for the development of new drugs.

Objective To observe the effect of WeChat -based health education on young patients with initial treatment of pulmonary tuberculosis(TB).Methods A total of 180 TB patients were randomly divided into control group and observation group,90 cases in each group.All patients received health education for six months under the guidance of specialist nurses and physicians,but WeChat-based health education for the observation group and telephone health education for control group.Patients of the two groups were evaluated with TB cognitive level and compliance at 6 months after discharge.Results The pulmonary tuberculosis knowledge level of the observer group was significantly higher than that of the control group (89.8%vs 73.3%),the difference was statistically significant (χ2 =11.07,P<0.01);And after 6 months of follow-up,in the observation group,the compliances of patients taking medicine on time(97.8%vs 80.0%,χ2 =15.59,P<0.01),reasonable diet(95.5%vs 81.1%,χ2 =23.24, P<0.01),moderate exercise(97.8%vs 83.4%,χ2 =36.51,P<0.01) and timely referral(96.7% vs 82.2%,χ2 =20.63,P<0.01) were higher than those in the control group,the differences were statistically significant (all P<0.01).Conclusion WeChat -based health education is effective for improving TB cognitive level and the compliance of the patients.Since WeChat has been widely used,WeChat-based health education can be promoted.

Objective To investigate the serum levels of PGⅠ,PGⅡ,TK1,TSGF and CEA,CA724 in gastric cancer and eval-uate the application value of combined detection the above tumor markers in diagnosis of gastric cancer.Methods The serum levels of TSGF were measured in 94 patients with gastric cancer and 85 healthy control by rate method.PGⅠ,PGⅡ,TK1 and CEA,CA724 were detected by electrochemiluminescence method.Results PGⅠand PGⅠ/PGⅡwere lower than healthy control in serum of patients with gastric cancer (both P<0.05).There was no difference in PGⅡ (P>0.05),and other tumor markers were all higher than healthy control (all P<0.05).The sensitivity of PGⅠ,PGⅠ/PGⅡ were better than TK1,CEA and CA724 (all P<0.05),the specificity of PGⅠ/PGⅡ,CEA were better than TSGF (both P<0.05),the accuracy of PGⅠ,PGⅠ/PGⅡ were better than CA724 and TSGF alone (all P<0.05).When combined TSGF,TK1 and PGⅠ/PGⅡ,PGⅠ,the sensitivity was better than combined PGⅠ/PGⅡand PGⅠ alone (P<0.05).Then when added CEA, CA724,this sensitivity improved up to 82.98%.Although the combined detection would show a lower specificity,it still keep high to 84.71%.Combined detection improved the accuracy in diagnosis of gastric cancer,up to 83.80%.In this re-search,There was no difference in sensitivity,specificity and accuracy between the group of PGⅠ+PGⅠ/PGⅡ+TSGF+TK1+CEA and the group of PGⅠ+PGⅠ/PGⅡ+TSGF+TK1+CEA+CA724.Conclusion Compared with CEA and CA724 popular used in clinic,PGⅠ/PGⅡand PGⅠshowed a better application value.The group of PGⅠ+PGⅠ/PGⅡ+TSGF+TK1+CEA showed the best sensitivity.Combined detection of serum levels of PGⅠ,PGⅠ/PGⅡ,TSGF,TK1 ,CEA can significantly raise the sensitivity and accuracy in diagnosis of gastric cancer.

Objective Diallyl disulfide ( DADS) has achieved remarkable effects in treatment and research of diverserfied cancers.The article was to explore the effects and the mechanism of DADS on the xenograft growth of human small cell lung cancer ( SCLC) cells in nude mice . Methods A total of 25 nude mice were selected to establish xenograft model of NCI-H446 human SCLC cells.The nude mice bearing with SCLC H446 were divided into 5 groups by random selection:positive control group(DDP 66 mg/kg), negative control group(physiological saline), 20 mg/kg DADS group, 60 mg/kg DADS group and 180 mg/kg DADS group, which is 40.6%, 53.1%and 66.4%, respectively.The growth of xenograft tumor in mice was observed after being treated with differ-ent concentrations of DADS .The morphological changes of the tumors were examined under light microscopy .Phase distribution and apoptosis of xenograft cells were analyzed by flow cytometry ( FCM) . Results The growth of xenograft tumor were inhibited signifi-cantly by DADS, resulting in decreased cell density and cellular atypia .Moreover, xenograft cell cycle was blocked in G 2/M and cell apoptosis rate was enhanced . Conclusion DADS can significantly inhibit the growth of NCI-H446 cells and lead to apoptosis .

Objective To explore pre-hospital delay factor of coronary reperfusion therapy for ST-elevation acute myocardial infarction (STEAMI) patients presenting with non-chest pains. Methods A retrospective observation was conducted. The clinical data of STEAMI patients underwent emergency percutaneous coronary intervention (PCI) admitted to Luoyang Central Hospital Affiliated to Zhengzhou University from August 2013 to August 2015 were analyzed. The patients were divided into chest pain group and non-chest pain group according to the presence of chest pain or not. Clinical characteristics were compared between the two groups, and incidence of major adverse cardiac events (MACE), door-to-balloon time, door-to-electrocardiograms (ECG) time and ECG-to-balloon time were evaluated. Influencing factors of pre-hospital delay was analyzed by logistic multiple stepwise regression. Results A total of 259 patients with STEAMI were enrolled, including 154 patients with chest pain and 105 presented with non-chest pains. Compared with chest pain group, the patients in the non-chest pain group were older (years: 68.12±8.93 vs. 62.34±7.12, P < 0.05), less female (26.67% vs. 42.20%, P< 0.05), and had a higher past history of angina, stroke and heart failure (27.61% vs. 13.63%, 31.42% vs. 18.83%, 26.67% vs. 11.68%, respectively, all P < 0.05), and higher percentage of Killip ≥ Ⅲ patients (15.24% vs. 6.49%, P < 0.05), the lower ambulance use (26.67% vs. 44.81%, P < 0.01), longer hospitalization time (days: 12.50±2.89 vs. 9.50±2.67, P < 0.05), higher incidence of MACE (19.05% vs. 9.09%, P < 0.05), longer door-to-balloon time and door-to-ECG time (minutes: 159.01±51.21 vs. 115.31±36.74, 53.06±18.17 vs. 30.35±9.93, both P < 0.01). It was shown by logistic multivariate regression analysis that no-chest pain [odds ratio (OR) = 5.14, 95% confidence interval (95%CI) = 2.34-10.81, P < 0.001], age ≥ 65 years old (OR = 1.43, 95%CI = 0.93-2.99, P = 0.022), diabetes (OR = 1.57, 95%CI = 0.66-2.15, P = 0.015) and no-ambulance transport (OR = 1.55, 95%CI = 0.73-2.75, P < 0.001) were risks factors of coronary reperfusion delay ≥ 2 hours. Conclusions STEAMI patients presenting without chest pain showed higher incidences of MACE, longer time of ECG obtained and initial PCI time delay. Clinicians should try to reduce the delay time of the patients in order to improve patient survival rates.
