ObjectiveTo investigate the effect and mechanism of total saponins from Panax japonicus （TSPJ） on white adipose tissue （WAT） browning/brown adipose tissue （BAT） activation in C57BL6/J male mice fed on a high-fat diet （HFD）. MethodThirty-two C57BL6/J male mice （8-week-old） were randomly divided into a normal group， a model group， a low-dose TSPJ group， and a high-dose TSPJ group. The mice in the low-dose and high-dose TSPJ groups were given TSPJ for four months by gavage at 25， 75 mg·kg^-1·d^-1， respectively， and those in the other groups were given 0.5% sodium carboxymethyl cellulose （CMC-Na） accordingly. After four months of feeding， all mice were placed at 4 ℃ for acute cold exposure， and the core body temperature was monitored. Subsequently， all mice were sacrificed， and BAT and inguinal WAT （iWAT） were separated rapidly to detect the corresponding indexes. Hematoxylin-eosin （HE） staining was used to observe the morphological changes in each group. The effect of TSPJ on the mRNA expression of uncoupling protein 1 （UCP1）， fatty acid-binding protein 4 （FABP4）， cytochrome C （CytC）， PR domain-containing protein 16 （PRDM16）， elongation of very long chain fatty acids protein 3 （ELOVL3）， peroxisome proliferator-activated receptor γ （PPARγ）， and peroxisome proliferator-activated receptor-γ coactivator-1α （PGC-1α） in iWAT and BAT was detected by Real-time polymerase chain reaction （Real-time PCR）. Western blot was also used to detect the protein expression of UCP1， PRDM16， PPARγ， and PGC-1α in BAT and iWAT of each group. The effect of TSPJ on UCP1 expression in BAT and iWAT was detected by immunohistochemistry. Result① Compared with the model group， TSPJ could decrease the body weight and proportions of iWAT and BAT in the HFD-induced mice （P<0.05， P<0.01）. ② The body temperature of mice in the model group decreased compared with that in the normal group in the acute cold exposure tolerance test （P<0.05）. The body temperature in the high-dose TSPJ group increased compared with that in the model group （P<0.01）. ③ Compared with the normal group， the model group showed increased adipocyte diameter in iWAT and BAT and decreased number of adipocytes per unit area. Compared with the model group， the TSPJ groups showed significantly reduced cell diameter and increased number of cells per unit area， especially in the high-dose TSPJ group. ④ Compared with the normal group， the model group showed decreased mRNA expression of FABP4， UCP1， CytC， PRDM16， ELOVL3， PGC-1α， and PPARγ in adipose tissues of mice （P<0.05， P<0.01）. Compared with the model group， after intervention with TSPJ， the mRNA expression was significantly up-regulated （P<0.05， P<0.01）. ⑤ Compared with the normal group， the model group showed decreased protein expression of UCP1， PRDM16， PPARγ， and PGC-1α in adipose tissues of mice （P<0.05， P<0.01）. Compared with the model group， after intervention with TSPJ， the protein expression increased significantly （P<0.05， P<0.01）. ConclusionTSPJ could induce the browning of iWAT/BAT activation and enhance adaptive thermogenesis in obese mice induced by HFD. The underlying mechanism may be attributed to the activation of the PPARγ/PGC-1α signaling pathway.

Objective:To investigate whether long non-coding RNA(lncRNA) AW112010 can improve insulin resistance in aging adipocytes through the miR-204/POU2F2 signaling pathway.Methods:In vivo experiment: C57BL/6 mice were divided into young control group(4 months old) and aging model group(18 months old) based on body weight. The expression levels of AW112010, miR-204-5p, POU2F2, aging related indicators(p16, p21), and insulin signaling pathway genes [insulin receptor(INSR), insulin receptor substrate 1(IRS1), phosphatidylinositol kinase(PI3K), protein kinase B(AKT)] in epididymal adipose tissue were detected using real-time fluorescence quantitative PCR(RT-qPCR) and Western blotting. In vitro experiment: Using adriamycin(ADR) to induce 3T3-L1 aging adipocyte model, β-gal staining was used to observe cellular senescence, and miR-204 inhibitor and miR-204 mimic small interfering RNA were successfully constructed and transfected into 3T3-L1 adipocytes. Results:RT-qPCR and Western blot results showed that compared with the young group, the expression of AW112010 in the adipose tissue of aging mice was increased, while the expression of miR-204-5p was decreased. The expressions of POU2F2, p16, and p21 in the adipose tissue of aging mice were increased, while the expressions of INSR, IRS1, PI3K, GLUT4 mRNA and protein were decreased. The β-gal stainging results showed that the number of 3T3-L1 senescent adipocytes induced by ADR was significantly increased, and the expression levels of AW112010, POU2F2, p16, and p21 in ADR-induced senescent adipocytes were increased compared with the control group, while the expression levels of miR-204-5p, INSR, IRS1, PI3K, GLUT4 were decreased, and remaining glucose in the culture medium was increased. Compared with control, overexpression of miR-204 resulted in decreased expressions of aging indicators p16, p21, and target gene POU2F2 while the expressions of INSR and GLUT4 were increased.Conclusion:Upregulation of lncRNA AW112010 in adipocytes of aging mice may induce insulin resistance by targeting miR-204-5p/POU2F2/IRS1.

Kawasaki disease is an acute, systemic vasculitis that easily injures coronary arteries and is the leading cause of acquired heart disease in children.Although the cause of Kawasaki disease remains unknown, it is widely believed that the pathogenesis of Kawasaki disease is an inflammatory cascade caused by a combination of infection and genetic predisposition.Regulatory T cells, which express Foxp3 + , CD4 + and CD25 + , are a T-cell subpopulation specialized in immune suppression.There are some correlations between regulatory T cells and Kawasaki disease in pathophysiology, treatment and prognosis.The dysfunction of regulatory T cells may be involved with the pathogenesis of Kawasaki disease, but there are few researches on it.This article reviews the progress of regulatory T cells in Kawasaki disease in recent years and summarizes the mechanism of regulatory T cells in the occurrence and repair of Kawasaki disease, prospecting the research future of targeted regulatory T cells therapy in the prevention of coronary artery lesions in Kawasaki disease.

The irreversibility of nerve cell injury is the main pathological basis of disability in stroke patients. In recent years, it has been found that neural stem cells (NSCs) with multi-directional differentiation potential and self-renewal capacity can proliferate under stress in the adult central nervous system, migrate to the injured area and differentiate into neural cells, thus participating in the repair of nerve injury. However, due to the limited number of homing stem cells, it is difficult to make up for the vacancy caused by the massive necrosis of neurons. This paper reviews the molecular mechanism of NSCs homing under ischemia and hypoxia, and explains the application prospect of NSCs in ischemic stroke.

Kawasaki disease(KD) is an acute febrile vasculitis and approximate 10% to 20% children with KD are resistant to initial intravenous immunoglobulin(IVIG) treatment at a dose of 2 g/kg, who are named IVIGRKD.Treatments for IVIGRKD include second dose IVIG, second dose IVIG plus glucocorticoid, single intravenous injection of infliximab, intravenous or oral cyclosporine, subcutaneous injection of Anakinra, intravenous cyclophosphamide, and plasma exchange, etc.No evidence suggests which treatment method is better than the others.Therefore, early prediction and timely identification of IVIGRKD are extremely important.Unfortunately, most of current prediction models are based on the statistical analysis of retrospective data, and due to the discrepancy of region and race, their further application are limited.

OBJECTIVETo explore the trend change of the morbidity and mortality of colorectal cancer in China in order to provide reference to the prevention and control of colorectal cancer.

METHODSAccording to the 1-3 volumes of "Pathogenesis and death of malignancies in pilot program city and county of China", "Pathogenesis and death of cancer in China"(2003-2007) and "Registration annual report of tumor in China" published in 2011 and 2012, data of pathogenesis and death of colorectal cancer from 10 tumor registration spots, including Beijing urban, Shanghai urban, Wuhan urban, Harbin urban (defined as city urban), and Hebei Ci County, Jiangsu Qidong District, Zhejiang Jiashan District, Guangxi Fusui County, Fujian Changle District, Henan Lin County (defined as rural district), between 1988 and 2009 were collected. The morbidity and mortality were elucidated with world population standardized rate. Ratio of pathogenesis to death was calculated with crude rate of morbidity and mortality. Data of 22 years were enrolled into the linear regression analysis to calculate the annual change rate of morbidity and mortality statistically.

RESULTS(1) Colon cancer: morbidity presented increasing trend; male morbidity in city urban increased faster; mortality presented increasing trend as well; no significant difference of increasing velocity was observed between city urban and rural district; morbidity and mortality in city urban were higher compared to rural district; morbidity and mortality of males were higher compared to females; except stable Fujian Changle District, ratio of pathogenesis to death presented decreased trend in Shanghai urban and Hebei Ci County, and increased trend in other 7 spots (all P<0.05). (2) Rectal cancer: morbidity presented increasing trend, and its increasing velocity of city urban was faster compared to rural district; mortality presented decreased trend, especially in females, and this trend in rural district was worse compared to city urban; morbidity and mortality of males were higher compared to females, while no significant difference was observed between city urban and rural district; morbidity and mortality of males and females in Zhejiang Jiashan District were all decreased (all P<0.05); except stable Harbin city, ratio of pathogenesis to death presented increased trend in other 9 spots (all P<0.05). (3) Ratio analysis of morbidity and mortality showed that percentage of colon cancer increased gradually in all 10 spots between 1988-2009.

CONCLUSIONSIn the past 2 decades, the overall morbidity and mortality of colorectal cancer are higher in city urban and in male as compared with rural district and female. Colon cancer has higher morbidity than rectal cancer and its morbidity and mortality present increased trend, while morbidity of rectal cancer presents increased trend but its mortality presents decreased trend.
