BACKGROUND:High-density lipoprotein is related to lipid metabolism, but its function cannot be restricted to the scope of lipid metabolism. Simultaneously, exercise regulation has effects on the activity and amount of high-density lipoprotein, but the optimal movement pattern needs to be studied. OBJECTIVE:To offer the theoretical support for formulating fitness training and prospect the possible direction and reference in fol ow-up studying the biological function and exercise regulation of high-density lipoprotein. METHODS:PubMed database was searched for relevant articles published from 1990 to 2015 using the keywords of“HDL and exercise, HDL and biological function”in English. Final y, 44 articles were included in result analysis. RESULTS AND CONCLUSION:The biological functions of high-density lipoprotein mainly include high-density lipoprotein-mediated metabolism of glucose, protein and fat, anti-inflammation, antioxidation and insulin secretion, and at the same time, we summarize the effects of exercise on the concentration, numbers of molecular and components of high-density lipoprotein. The results indicate that the combination of resistance and endurance training is the best way for raising the concentration and functional effects of high-density lipoprotein.
3.A contrast on pathology and imaging in senile dementia of the Alzheimer type
Chinese Journal of Neurology 2000;0(04):-
Objective To explore the correlation of pathological changes and imaging through a control study on pathology and imaging of 4 cases of senile dementia of the Alzheimer type (SDAT).Methods By HE and Gallyas silver dyeing,four immunohistochemical methods were carried out The loss of neurons cells of all lobes of cerebral cortex,cingulate gyrus,amygdaloid nucleus,hippocampal gyrus,parahippocampal gyrus,meynert basal nucleus,substantia nigra,locus ceruleus,dorsal nucleus of vagus nerve,senile plaques (SP) and the changes of neurofibrillary tangles (NFT) were observed in detail The control study of pathology and imaging was carried out by comparison of CT in different phases before and after death of the patient.Results The degeneration of temporal lobe was marked: (1) The degeneration of middle frontal gyrus of cortex of frontal lobe was the most evident; (2) The degeneration of long gyrus was more evident than that of the short gyrus as the cortex of insular lobe was concerned; (3) The degeneration posterior part of cingulated gyrus was more evident than that of the anterior part.Conclusion The pathological findings of SDAT mentioned above are basically in conformity with the changes of imaging.

We are facing increasing stress and challenges because of the fierce competition and fast pace of daily work and life.In other words,we are exposed to more frequent and intense social stress.Continual and intense stress is known to be detrimental to human well-being.Stress has been regarded as a major contributing factor of human diseases.There-fore,it′s necessary to review the recent research progress in stress biomarkers that are of different types,such as cortisol,α-amylase,catecholamine,heat shock protein and cytokines.In this review,we will focus on the most well reported stress biomarkers,including cortisol and α-amylase.We hope that this review will enable researchers and practitioners to gain in-sights into stress biomarkers,which will lead to improved healthcare decisions regarding prevention,treatment and rehabili-tation of stress-related diseases.

Abstract: TGF-β/Smad signaling pathway has a wide range of biological activities and plays an important roles in regulating cell growth, adhesion, differentiation, cell dynamic balance, and immune responses. The higher activity of TGF-β/Smad signaling pathway may promote scar formation, organ fibrosis, immunosuppression, and late-stage cancer progression, while low activity may lead to inflammation, dysplasia, poor healing and oncogenesis. The function of the TGF-β/Smad signaling pathway is extremely complex and can exhibit inhibitory or enhancing effects on immunity and inflammation under different circumstances, but immunosuppressive and anti-inflammatory effects are dominant. During HIV infection, the TGF-β/Smad signaling pathway interacts with HIV in a complex manner as HIV proteins tat and gp120 can induce TGF-β expression. Meanwhile, this signaling pathway may also play a role in HIV infection and replication, latent virus reservoir, host immune deficiency and HIV-related inflammation. It is worth noting that even though TGF-β, which mainly exhibits anti-inflammatory effects, is induced by HIV, high levels of TGF-β do not seem to inhibit HIV-related inflammation. So far, the relationship between TGF-β/Smad signaling pathway and HIV infection has not been elucidated, and its role and mechanism in HIV infection and related illnesses need further exploration and validation. This review summarizes the relevant research progress on the TGF-β/Smad signaling pathway and HIV infection, and provides a reference for further understanding of HIV pathogenesis and exploring strategies of AIDS treatment.

Objective To observe the changes of LoVo cell growth by galectin-1.Methods Eukaryotic expression vector of galectin-1 was constructed and transfected into LoVo cells using lipofectamineRM 2000.Immunochemistry was employed to detect galectin-1 expresson.LoVo cell proliferation and apoptosis were observed.Results Galectin-1 eukaryotic expression vector pEGFP-C1/GAL1 was successfully constructed.Three cell clones,p-GAL1-LoVo and p-LoVo,transfected with pEGFP-C1/GAL1 and pEGFP-C1 correspondingly,and LoVo were cultured successfully.Galectin-1 expression downregulated Bcl-2 level only occurring in p-GAL1-LoVo cells.p-GAL1-LoVo cell proliferation was similar to p-LoVo and LoVo cells,but p-GAL1-LoVo cell apoptosis was increased(9.61?0.56)%,as compared with p-LoVo and LoVo cells,[(3.56?0.53)% and(3.46?0.46)% respectively](P
