AIM: To observe the effect of sibutramine in the treatment of obesity with different body weight. METHODS: Forty overweight subjects were divided into three groups according to their BMI: Group 1 (n=10), the early stage of obesity; Group 2 (n=11), obesity in degree Ⅰ; and Group 3 (n=19), obesity in degree Ⅱ. The patients conformed to the same standards of diet, sports and life style, and then took sibutramine 10 mg a day for 12 weeks. RESULTS: After taking the medicine for two weeks, the efficacy rate was 45.5 % (5) in Group 2 and 94.7 % (18) in Group 3 (P

Ginseng is a typical adaptogen which has resistance to various stresses. This effect is related to the hypothalamic-pituitary-adrenal (HPA) axis. As the main active ingredients, saponin has the similar structure to steroids. The regulation characteristics of ginseng saponin on the HPA axis are narrated from the aspects of total saponin and saponin monomers in this paper after the introduction of adaptation definition and HPA axis regulation mechanisms. Pharmacological effects of ginseng saponin and the regulation effect of HPA axis are summarized finally.

OBJECTIVE:To optimize the matrix formulation and preparation technological parameters of Compound Bingjia Cream. METHODS:To prepare water phase and oil phase matrix solutions respectively,and then the former was added into the lat-ter and well mixed together. The matrix formulation was optimized with the overall scores of appearance,high temperature,low temperature and oil and water stratification after centrifugal test as the evaluated indexes. High performance liquid chromatography was used to determine the content of metronidazole. Gas chromatography was adopted to determine the content of borneol. With the matrix temperature at the time of adding the main drug mixture,matrix quantity,emulsification method and emulsification time as observed factors,and the overall scores of metronidazole content,borneol content and the overall scores of preparation(the overall scores of appearance and stability tests) as the observed indexes,L9(34) orthogonal test was designed to optimize the preparation technological parameters of Compound Bingjia cream and verification for technology was conducted. RESULTS:The optimal oil phase matrix formulation was as follows as cetanol of 10 g,glyceryl monostearate of 16 g,stearic acid of 20 g,albolene of 8 g, while the optimal water oil matrix formulation as triethanolamine of 2 g,glycerinum of 24 g. The optimal preparation technological parameters were the matrix temperature of 50℃at the time of adding the main drug mixture,matrix of 300 g,emulsification meth-od of colloid emulsification,emulsification time of 30 min,where metronidazole content was 1.83%,borneol content 2.88%. The results of 3 verification tests showed the overall scores were all 25,with metronidazole content of 2.1%,2.1%,2.2%(RSD=2.71%,n=3),borneol content of 3.2%,3.3%,3.1%(RSD=3.12%,n=3). CONCLUSIONS:The optimal matrix formulation and technological parameters of the preparation are stable and feasible,and suitable for mass production.

In late 1998, a novel paramyxovirus named Nipah virus, emerged in Malaysia, causing fatal disease in domestic pigs and humans with substantial economic loss to the local pig industry. Pteropid fruitbats have since been identified as a natural reservoir host. Over the last two decades, the forest habitat of these bats in Southeast Asia has been substantially reduced by deforestation for pulpwood and industrial plantation. In 1997/1998, slash-and-burn deforestation resulted in the formation of a severe haze that blanketed much of Southeast Asia in the months directly preceding the Nipah virus disease outbreak. This was exacerbated by a drought driven by the severe 1997-1998 El Ni?o Southern Oscillation (ENSO) event. We present data suggesting that this series of events led to a reduction in the availability of flowering and fruiting forest trees for foraging by fruitbats and culminated in unprecedented encroachment of fruitbats into cultivated fruit orchards in 1997/1998. These anthropogenic events, coupled with the location of piggeries in orchards and the design of pigsties allowed transmission of a novel paramyxovirus from its reservoir host to the domestic pig and ultimately to the human population.

Objective To investigate the construction of compound membrane with corneal stromal cells and collagen-chitosan by tissue engineering technique and its biocompatibility.Methods Rabbit and human corneal stromal cells were separated and seeded into collagen-chitosan membrane.The compound membrane was transplanted into rabbit corneal stroma.Then the growth condition of keratocytes,the effect on normal keratocytes and degradation of compound membrane were detected by corneal confocal microscope,anterior OCT and histological and immunohistochemical methods ex vivo 1,2,4 weeks after grafting.Results The rabbit and human corneal stromal cells grown well in collagen-chitosan scaffold.The compound membrane degradated gradually after grafting.There was no necrosis and dissolvation.Corneal epithelium,stroma and endothelial cells were all normal.Conclusion Collagen-chitosan can be used as a biological scaffold for construction of corneal stroma.Corneal confocal microscopy and anterior OCT are new methods to observe the biological activity of constructed corneal stroma.

Objective: To explore the mechanism of high incidence of cardiovascular diseases and the levels of plasma lipids and oxidized lowdensity lipoprotein(Ox-LDL) in patients with rheumatoid arthritis(RA).Methods: Fifty-five patients with RA(24 case of active type,31 non-active) and 60 healthy controls were randomly chosen.Plasma lipids and Ox-LDL levels were studied.All the data were subjected to statistical analysis.Results: Compared with the control,total cholesterol(TC),LDL cholesterol(LDL-C) and apolipoprotein B(apoB) levels were increased in patients with active RA,while TC,triglyceride(TG),LDL-C,apoAⅠ,B and Ox-LDL levels were elevated in those with non-active RA.Furthermore,plasma lipids and Ox-LDL level decreased in the active patients as compared with the non-active ones,while only the change of apoAⅠhad statistical significance.The erythrocyte sedimentation rate was found negatively related with TC,LDL-C,high-density lipoprotein cholesterol(HDL-C) and apoAⅠ,while C-reacting protein was found negatively related with LDL-C and HDL-C.Conclusion: Ox-LDL and plasma lipid levels were changed in RA patients.Inflammation may induce changes of lipoprotein and play an important role in atherosclerosis.
