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.

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.

Doctors in the past dynasties always used ephedra to treat disease of exogenous wind-cold,cough,asthma and edema,but ignored its application in treating arthromyodynia.It could be deduced from the record of the books of Chinese medicine and prescriptions that ephedra had the nature of pungent and warm,could dispel wind and remove wetness,warm channel and expel cold,remove obstruction in collaterals.All of those were correspondent with the pathogenesis of arthromyodynia.Thus,ephedra can be widely used in types of arthromyodynia.Proven case was also included in this article.

Objective To investigate the effect of ulinastatin on acute lung injury in rats with severe heatstroke.Methods Fourty-eight rats were randomly (random number) assigned into control group (HS group,n =12),low dose Ulinastatin group (LUTI group,n =12),high dose Ulinastatin group (HUTI group,n =12) and non-thermal group (Sham group,n =12).Rats were prepared with pre-warm chamber to initiate heatstroke.The change of rectum temperature (Tc),heat-rate (HR) and mean arterial pressure (MAP) under heat-stress were recorded.The time-point of heatstroke onset and Tc ＞42 ℃ was observed.Arterial blood samples were draw at 0 min,20 min,40 min and 60 min for testing partial pressure of oxygen (PaO2) and partial pressure of carbon dioxide (PaCO2).Bronchoalveolar lavage fluid (BALF) were collected at 60 min,and the concentrations of tumor necrosis factor-α (TNF-α),interleukin-1β (IL-l β) and interleukin-6 (IL-6) in BALF were measured with enzyme linked immunosorbent assay kit.Lung tissues were harvested for observing pathological change and measuring the expression of iNOS with Western blot test.Results Compared with HS group,the time-point of Tc ＞ 42℃ (P =0.00),severe heat-stroke (P =0.00) and the median of survival time (P =0.00) in LUTI and HUTI groups were significantly increased.At 60min after heat-stress,the level of PaO2 in HS group was much lower than those in other groups (P =0.00).But there were no differences between LUTI and HUTI groups (P =0.91).The value of PaCO2 in HS group was much higher than those in other groups (P =0.00).And the differences between LUTI and HUTI groups were no significant (P =0.79).The concentrations of TNF-α,IL-1β and IL-6 in HS group was the highest in four groups (P =0.00,P =0.04 and P =0.04),followed by LUTI,HUTI and Sham group.The concentrations of proinflammatory cytokine in LUTI were higher than those in HUTI group (P =0.02,P =0.00,P =0.00).Compared with HS group,the pathological injuries were alleviated in LUTI and HUTI group (P =0.00).The expression of iNOS in lung tissue of HS group was strengthened than LUTI and HUTI group (P =0.00),and there was a significant difference between LUTI and HUTI group (P =0.03).Conclusion Ulinastatin improves respiratory dysfunction and the prognosis of severe heatstroke rats through reducing the inflammatory and oxidative injury in lung tissue.
