Musashi2-Numb interaction plays a vital role in the progression of myeloid leukemia. However, its potential role in solid cancers has rarely been reported. We investigated the coordinate function of Musashi2-Numb in the development of pancreatic cancer (PC) in vitro and vivo. Both Musashi2 protein and mRNA levels were higher in PC tissues than that in paired normal pancreas (P<0.05). Musashi2 overexpression and Numb positive expression were positively and negatively associated with tumor size and UICC stage, respectively (P<0.05). Multivariate analysis identified Musashi2 and Numb as adverse and favorable independent indicators for the survival of PC patients. Moreover, patients with high Musashi2 expression combining with negative Numb expression had a significantly worse overall survival (P=0.001). The negative relationship between Musashi2 and Numb was found at both PC tissue and cell levels. These two endogenous proteins can be co-immunoprecipitated from PC cell lines, and Musashi2 silence up-regulated Numb protein in vitro and vivo. Meanwhile, its silence decreased cell invasion and migration in vitro and inhibited the growth of subcutaneous tumors and the frequency of liver metastasis in vivo. However, Numb knockdown significantly reversed the decrease of cell invasion and migration induced by Musashi2 silence. Musashi2 promotes the development and progression of pancreatic cancer by down-regulating Numb protein. The interaction of Musashi2-Numb plays a significant role in the development and progression of PC.

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.

Objectives The aim of this study was to investigate the efficacy and safety of a new paclitaxel-coated balloon catheter in the treatment of stenotic or occluded femoropopliteal arteries. Background The incidence of restenosis can be reduced by the use of drug-coated balloons. However, dose, coating composition, and technology are decisive for efficacy. Methods Two hundred Chinese patients with peripheral arterial occlusive disease were prospectively randomized to treatment with new paclitaxel-coated or standard uncoated balloon catheters. The primary endpoint was angiographic late lumen loss at 6 months, measured by a blinded core laboratory. Secondary angiographic endpoints (6 months) and specific clinical endpoints (1 year) were binary restenosis, ankle-brachial index, Rutherford stage, clinically driven target lesion revascularization, and amputation. Results Patients’ mean age was 66 years, 74% were men, 31% were smokers, and 55% had diabetes. Patients were in Rutherford stages 2 through 5, with a mean lesion length of 150 mm; 25% had in-stent restenosis, 55% had occlusion or partial occlusion, and 20% underwent provisional stenting. Late lumen loss at 6 months was available for 89%, and clinical follow-up was available for >95% per group. Mean late lumen loss was 0.05 ± 0.73 mm with coated balloons and 1.15 ± 0.89 mm with uncoated balloons (p < 0.001). Correspondingly, the rates of restenosis were 22.5% and 70.8% (p < 0.001). After 1 year, the rates of target lesion revascularization were 7.2% and 39.6% (p < 0.001), and Rutherford class and ankle-brachial index improved more markedly in the coated group (p < 0.046 and p = 0.023, respectively). One major amputation was recorded in the control group. No coating-related adverse events were observed for doses of up to 43 mg paclitaxel per patient. Conclusions In this medium-sized trial with long superficial femoral artery lesions, the use of paclitaxel-coated balloon catheters markedly improved angiographic and clinical outcomes of interventions despite advanced disease in the majority of patients. © 2016 American College of Cardiology Foundation

BACKGROUND The aim of this study was to determine the plasma levels of cyclooxygenase-2 (COX-2) and visfatin in different stages and different subtypes of migraine headaches compared to a control group to elucidate the pathological mechanisms involved. MATERIAL AND METHODS We recruited a case-control cohort of 182 adult migraine patients and 80 age-matched and gender-matched healthy controls. The migraine patients were divided into two groups: the headache-attack-period group (Group A, n=77) and the headache-free-period group (Group B, n=105). The two groups were further divided into subgroups according to whether they had aura symptoms. Solid phase double antibody sandwich enzyme-linked immunosorbent assay (ELISA) was used to measure the plasma levels of COX-2 and visfatin. Statistical analysis was performed using SPSS 17.0. RESULTS The plasma levels of COX-2 and visfatin in the headache-attack-period group were significantly higher than in the headache-free-period group and the control group; there were no significant differences between the headache-free group and the control group. There were no significant differences in plasma levels of COX-2 and visfatin between the subgroups: headache-attack-period with aura subgroup and the headache-attack-period without aura sub group. CONCLUSIONS COX-2 and visfatin participated in the pathogenesis of migraine headaches. The presence of aura had no effect on the serum levels of COX-2 and visfatin.

Aim: To assess the potential relationship between intelligence structure abnormalities and whole-brain functional connectivity in children with primary nocturnal enuresis (PNE) with resting-state functional magnetic resonance imaging (fMRI) to provide insights into the association between these two seemingly unrelated conditions. Methods: Intelligence testing and fMRI data were obtained from 133 right-handed children, including 67 PNE children (M/F, 39:28; age, 10.5±1.2 y) and 66 age-matched healthy controls (M/F, 37:29; age, 10.1±1.1 y). All intelligence tests were performed using the China-Wechsler Intelligence Scale for Children (C-WISC). Each subject's full intelligence quotient (FIQ), verbal IQ (VIQ), performance IQ (PIQ), and memory/caution (M/C) factor was measured and recorded. Resting state fMRI scans were performed on a 3.0-T MR scanner and post-processed using REST software. Comparisons of z-score correlation coefficients between distinct cerebral regions were used to identify altered functional connectivity in PNE children. Results: The PNE group had normal FIQ, VIQ, and PIQ values, indicating no significant variation from the control group. However, the M/C factor was significantly lower in the PNE group. Compared to the control group, PNE children exhibited overall lower levels of functional connectivity that were most apparent in the cerebello-thalamo-frontal pathway. The M/C factor significantly correlated with z-scores representing connectivity between Cerebellum_Crus1_L and Frontal_Mid_R. Conclusion: PNE children exhibit intelligence structure imbalance and attention deficits. Our findings suggest that cerebello-thalamo-frontal circuit abnormalities are likely to be involved in the onset and progression of attention impairment in PNE children. © 2013 Yu et al.

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.

In this study, we examined the mechanisms associated with EZH2 mediation of apoptosis and chemoresistance to arsenic trioxide (ATO) in acute myeloid leukemia (AML) cell lines through the Wnt/-catenin signaling pathway. The induction of spontaneous apoptosis observed in multiple EZH2-silenced leukemic cell lines was assessed by flow cytometry, and levels of Wnt/-catenin-related expression were determined by western blot analysis. In comparison with AML control cells, EZH2-knockdown cells exhibited increased apoptosis and significant downregulation of -catenin expression, as well as decreases in GSK-3 phosphorylation and -catenin activation (p<0.05 for all measurements). Additionally, EZH2 knockdown sensitized AML cells to induced cell death following administration of chemotherapeutic ATO. Our results suggested that EZH2 in leukemic cell lines might inhibit ATO-induced apoptosis and that EZH2 may be a potential therapeutic target in AML patients undergoing ATO treatment. Our findings provide new insights into the role of ATO and EZH2 in regulating AML progression.

Objectives: To provide evidence of the clinical efficacy of Xuebijing (XBJ) on blood coagulation in patients with sepsis. Methods: We conducted this meta-analysis in The People’s Hospital of Liaoning Province, Shenyang, China between December 2013 and May 2014. We searched a number of databases for relevant randomized controlled trials (RCTs) published before December 2013 using the keywords ‘Xuebijing’, ‘coagulation’ and ‘sepsis’. Statistical analysis was performed with Review Manager 5.2 from the Cochrane Collaboration. Results: Fourteen RCTs involving 867 patients were included. Compared with placebo, XBJ injection significantly improved platelets (mean differences [MD] = 42.14, 95% confidence interval [CI]: 22.42 - 61.86, p<0.00001), shortened the activated partial thromboplastin time (MD = -4.81, 95% CI: -7.86 - [-1.76], p=0.002), shortened the prothrombin time (MD = -2.33, 95% CI: -4.15 - [-0.51], p=0.01), and shortened the thrombin time (MD = -2.05, 95% CI: -3.52 - [-0.58], p=0.006). However, no significant difference was found between the XBJ injection and the placebo group for fibrinogen (MD = 0.21, 95% CI: -0.38 - 0.81, p=0.48). Conclusion: Xuebijing injection may improve coagulopathy in patients with sepsis. High-quality and large sample clinical trials are needed for confirmation. © Saudi Med J 2015.

Although metastasis-associated protein 1 (MTA1) has been widely linked to tumor metastasis, the relevant mechanisms remain to be elucidated, especially in gastric cancer. The aim of this study was to examine whether the MTA1 gene is associated with the process of proliferation and invasion by regulating several molecular targets in gastric cancer. MTA1 expression in 61 gastric cancer tissue and adjacent noncancerous tissues was analyzed by immunohistochemistry. The prognostic value of MTA1 for overall survival and disease-free survival was determined by Kaplan–Meier estimates, and the significance of differences between curves was evaluated by the log-rank test. Furthermore, overexpression of MTA1 in SGC7901 and BGC823 cells promoted cell cycle progression, cell adhesion, and cell invasion. Our study found that MTA1 is overexpressed in gastric cancers, which contributes to malignant cell growth by facilitating cell cycle progression through upregulation of cyclin D1 and accelerates the migration and invasion of human gastric cancer cells by regulating expression of fibronectin and MMP2/MMP9. Taken together, MTA1 was involved in the pathogenesis of gastric cancer and might be a candidate therapeutic target in gastric cancer. © 2015 Yao et al.

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.
