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.

Objective To study the efficacy and safety of reboxetine and citalopram in treating retardant depression.Methods A total of 59 patients with retardant depression were randomly divided into reboxetine group(n=29)and citalopram group(n=30)for the treatment of 6 weeks.The patients were assessed with the Hamilton depression scale(HAMD)and treatment emergent symptom scale(TESS).Results At the end of 6 weeks,the total scores of HAMD in reboxetine(18.48±6.38)group and citalopram(11.60±4.46)group both significantly decreased(P＜0.001).Between two groups,the efficacy(82.8% and 56.7%)had significant differences(P＜0.05)but side effects had no statistical significance.Conclusion Reboxetine has significant curative efficacy,milder adverse effects and higher safety for treating patients with retardant depression.

Objective To investigate the effect of thymosin α1 on immun ologic function and cytokines in the abdominal sepsis patients.and naddiscuss the therapeutic function of thymoin α1 in sepsis.Methods Thirty-eight sepsis patients admitted between May 2006 and May 2007 in the Hospital of Weifang Medical University.Patients were divided into the treatment group(20 cases)and control group(18 cases)randomly.Thymosin α1 was used in the treatment group on the basis of infection controlled.The concentration of cytokines(TNF-α,IL-6,IL-10)and the percent age of CD3,CD4,NK cell were observed.Results The concentrations of TNF-α and IL-6 were increased significantly in bothgoups.But it was more prominently in the control group.The concentration of IL-10 and the percent age of CD3,CD4,NK cell increased more significantly in thymosinod treatment group than those in the control group.Conclusions Thymosincd canmodulate the release of TNF-α,IL-6,IL-10 and mitigate the inflammatory reaction,which may improve the immunologic function.
