Background: The aim of this study was to observe the change in plasma PPARs (peroxisome proliferator-activated receptors) level during various periods and in different subtypes in migraine patients. Material/Methods: We divided 227 patients with migraine into 2 main groups: the attack period group (n=98) and the attackfree period group (n=129). Patients were further divided into 4 subgroups according to whether they had aura symptoms. The control group consisted of 100 healthy subjects. We collected the clinical data of patients and measured the plasma levels of PPARs using enzyme-linked immunoassay (ELISA). We used SPSS software for statistical analysis. Results: We found no significant difference in age, BMI, blood pressure, or blood lipid level among migraine patients during the headache attack period and during the headache-free period compared with the control group. The PPARα and PPARβ/δ levels during the headache attack period were significantly higher than during the headache free period and in healthy controls. The PPARg levels during the headache attack period were significantly lower than those during the headache-free period and in the healthy control group. The PPARγ levels during the headache attack period were significantly different from those during the headache-free period, regardless of presence or absence of aura. The PPARs levels during the headache-free period were not significantly different from those of the healthy control group. The level of PPARs has no significant differences between migraine with aura group and without aura group, regardless of whether headache attack. Conclusions: PPARs involved in the pathogenesis of migraine. Presence of absence of aura had no obvious effect on PPARs level. © Med Sci Monit, 2015. Source

To study the relationship between CT imaging classification criteria and the prognosis of severe acute pancreatitis (SAP). From January 2000 to December 2009, 62 cases with SAP were analyzed, retrospectively. They were all executed CT examination in 72 h after admission, and their CT imaging were classified as grade C (n = 13), grade D (n = 26), and grade E (n = 23) according to the Balthazar classification criteria and also classified as grade I (n = 11), grade II (n = 39), grade III (n = 12) according to the Balthazar CT severity index (CTSI) criteria, respectively. The values of these two different classification criteria in assessing the prognosis of SAP were studied, such as length of hospital stay, fever days, fasting days, white blood cell recovery days, serum amylase recovery days, pancreatic pseudocyst, organ failure, need for transit operations, and death. By studying the receiver operating characteristic (ROC) curves, which were drawn by the area under cures, the values of the two different classification criteria were compared in assessing the prognosis of SAP. The Balthazar classification criteria was valuable in assessing white blood cell recovery days (F = 4.035, P = 0.023) and pseudocyst (χ(2) = 8.066, P = 0.018). No statistical differences were found, however, between other clinicopathological parameters and the prognosis of SAP, according to the Balthazar classification criteria. The patients with low-grade of CTSI classification criteria enjoyed better prognosis, and patients in grade I or II got lower incidence of organ failure, need for transit operations and pseudocyst than that in grade III. The results above suggested that CTSI classification criteria, comparing with Balthazar CT classification criteria, was more valuable in predicting the incidence of organ failure, pseudocyst, need for transit operation, and mortality in SAP (P < 0.01). The CTSI classification criteria has a great value in assessing the prognosis of SAP. Source

Myocardial infarction is a leading cause of mortality and morbidity worldwide. Although essential for successful recovery, myocardium reperfusion is associated with reperfusion injury. Icariin, a major flavonoid of Epimedium koreanum Nakai, has been proven to exert efficacy for improving cardiovascular function. We investigated the molecular effect and signal pathway of icariin on cardiac ischemia/reperfusion injury. In an in vivo model of infarct in rats, icariin (10 mg/kg) significantly attenuated myocardial infarct size induced by ischemia/reperfusion (I/R). From the TUNEL assay, icariin reduced the apoptotic cell induced by I/R and decreased blood indicators of creatine kinase, ischemia-modified albumin, and lactate dehydrogenase. All this effect was antagonized by the PI3K inhibitor LY294002. Meanwhile, icariin activated the PI3K/Akt/eNOS pathway. The PI3K inhibitor LY294002 suppressed icariin-mediated protective effect. These results suggest that icariin protects against myocardial ischemia reperfusion injury in rats by activating the PI3K/Akt/eNOS-dependent signal pathways and may be a useful drug for angiogenic therapy. © 2015, Springer Science+Business Media New York.

Objective: To objectively evaluate lipid-lowering therapy and low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein cholesterol (non-HDL-C) goal attainment in metabolic syndrome (MetS) patients in China. Methods: Data regarding patient demographics, lipid-lowering agents, lipid parameters, and cardiovascular risk profiles were analyzed for 25,317 patients of the Dyslipidemia International Study-China. MetS was defined according to criteria of the NCEP-ATP III and the 2007 Chinese Guidelines on Prevention and Treatment of Dyslipidemia in Adults. Results: The prevalence of MetS was 39.9% and 37.4% according to the NCEP-ATP III and 2007 Chinese Guidelines, respectively. LDL-C goal attainment occurred less frequently among MetS patients than in those without MetS (NCEP-ATP III: 46.9% vs 68.6%; 2007 Chinese Guidelines: 52.2% vs 67.1%; p<0.001). Similar results were obtained for non-HDL-C goal attainment (2007 Chinese Guidelines: 51.0% vs 72.0%; p<0.001). As the risk class increased, LDL-C and non-HDL-C goal attainment decreased. In multivariate logistic regression analysis, DM, CHD, ischemic cerebrovascular disease, and higher SBP were independently associated with failure to achieve LDL-C and non-HDL-C goal attainment. The type of lipid-lowering agent was not significantly correlated with LDL-C not at goal attainment but was correlated with non-HDL-C not at goal attainment. Conclusion: Goal attainment for both LDL-C and non-HDL-C occurs less frequently in MetS patients than in those without MetS. The residual risk due to elevated non-HDL-C levels should be considered in MetS patients. Strategies for controlling multiple risk factors in order to decrease the residual risk related to dyslipidemia in MetS patients should be recommended in future guidelines. © 2014 Elsevier Ireland Ltd.

Aims: To study the expression of Gli1, MDM2 and p53 for clinical significance in pancreatic cancer (PC), and their functional relationship in regulating the biological behaviour of PC cells. Methods and results: Immunohistochemistry showed that the expression of Gli1, MDM2 and p53 was much higher in 57 cases of PC than in paired normal pancreatic tissues, and was positively associated with tumour UICC stage and T stage (P < 0.05). Patients with expression of Gli1 only or coexpression of Gli1 and MDM2 had significantly worse overall survival than patients with negative expression (P < 0.05). RNA interference showed that p53 knockdown increased the protein level of Gli1 but decreased the level of MDM2, and enhanced cell invasion and migration in wild-type p53 Capan-2 cells; whereas Gli1 or MDM2 knockdown did not change p53 expression, but decreased the protein level of MDM2 or Gli1, respectively, and inhibited cell invasion and migration in mutant p53 PANC-1 cells. Conclusions: Overexpression of Gli1, MDM2 and mutant p53 contributes to the development and progression of PC, and plays an important role in predicting PC patients' prognosis. Moreover, we report a positive association between Gli1 and MDM2 in PC cells, but their relationship with p53 is dependent on wild-type or mutant p53 status. © 2013 John Wiley & Sons Ltd. Source
