Objective: The effects of two fat substitutes, sucrose polyester(SPE) and triglyceride of short fatty acids(TRIS)on lipid metabolism in rats were studied. Methods: Diets containing either SPE or TRIS were fed to rats for 30d. Male Wistar rats were allowed free access to one of three diets: a control diet containing 20% corn oil, SPE group diet containing 10% SPE and 10% corn oil, TRIS group diet containing 20% TRIS. Plasma glucose, TG, TC, HDL C, LDL C, ApoA I, ApoB were analysed. Results: Dietary fat substitutes lowered total energy consumption and body weight 8.1%?4.1%and 12.3% ?16.0% respectively. Two fat substitutes lowered plasma glucose, TG, TC, LDL C, VLDL C, ApoB level and increased HDL C and ApoA I level. TRIS could decrease TC/HDL C, LDL C/HDL C, ApoB/ApoA I more significantly than SPE. Conclusion: TRIS and SPE have the potential benefits on lipid metabolism and energy intake control in rats, TRIS is more efficient than SPE.

Advanced non-small cell lung cancer(NSCLC)accounts for all NSCLC 45% . In recent years,chemotherapy combined with radiotherapy has become a new standard for NSCLC. On NSCLC radiothera-py and chemotherapy(CRCT),radiation total dose,fractionation method,different chemotherapy combined with radiotherapy have many details in the efficiency and toxicity tolerance,which are still in the exploration.

Phyllosphere and epiphytes have attracted significant interest of more and more researchers by their unique biological characteristics. Progress of research on phyllosphere and epiphytes was summarized in this paper, and the special emphasis was put on the characteristic of phyllosphere, microbial communities, invasion and the location of bacteria on leaf surfaces. Some ideas for further studies on phyllosphere microbes were also proposed.

Objective To observe the effect of new moist dressings on pressure ulcers after spinal cord injury. Methods 58 spinal cord injured patients complicated with pressure ulcers were divided into observation group (n=29) and control group (n=29). The observation group accepted moist dressings, while the control group accepted routine dry dressings, TDP and ultraviolet irradiation. The incidence of im provement were recorded 2 weeks after treatment, and the time of healing were compared. Results 11 cases cured, 17 cases relieved in the observation group, and it was 5 and 18 cases in the control group, respectively (P<0.05). It spent (26.69±16.48) days to cure in the observa tion group, and (38.24±22.47) days in the control group (P<0.05). Conclusion The moist therapy may promote the cure of pressure ulcers af ter spinal cord injury, and shorten the time of cure.

Interferon ( IFN) plays an essential role in antiviral infection.Interferons are divided into different categories according to their structure and function.People have attached increasing importance to TypeⅠinterferon( IFN-Ⅰ) in light of its unusual antiviral mechanism.This review is intended to shed light on IFN-Ⅰ,including its antiviral function,signal pathway and regulation.

Pulsed wave Doppler echocardiograpdy was performed in eighteen cases with chronic mitral regurgitation(CMR)and 21 normal individuals td detect the quantitative changes of the mitral diastolic flow spectrum.The results showed that the pseudonormalization of mitral flow spectrum in CMR was actually caused by impaired left ventricle(LV)active relaxation and decreased LV compliance:It thus masked the LV diastolic dysfunction in CMR.E-wave pressure gradiant(E-PG),A-wave pressure gradiant(A-PG),isovolumic relaxation time(IVRT),E deceleration time(E-DT)and LV filling time(LVFT)in CMR group were significantly different in from those in normal group(P<0.01).Therefore it is essential to integrate these parameters as the indexes to evaluate the LV diastolic dysfunction in CMR.
