Objective To investigate the difference of TCM body constitution betweenpeople of the Shimian county and Chengdu city. Methods 200 sub-health patients in clinic of Shimian TCM Hospital were selected randomly. Another 200 sub-health patients in clinic of the Second Sichuan Province Hospital of TCM wererandomly selected. The two groups were identified with TCM body constitution based on the clinical symptoms, tongue, pulse condition, etc. Comparisons on body constitution were made between the two groups. Results In Chengdu, patients withbalance constitution and Qi deficiency constitution (respectively have the proportion of 33.0% and 20.0%)were significantly higher than thoseof Shimian County(the proportion of the two wererespectively 4.0% and 6.0%);while Shimian County have a significantly higher ratio of phlegm dampness and blood stasis constitution(43.5% and 13.0%)than those in Chengdu city(the proportion of the two wererespectively 8.0%and 4.0%), P<0.01. Conclusion Because of different regions, the population constitution ratio wasdifferent, so the disease tendency wasalso somewhat different. Therefore, physicians should give full consideration to the regional factors in diagnosing and treating patients.

Purpose:To investigate the treatment effect and toxicity of regimen containing ifosfamide (IFO) and etoposide (VP16) on relapse ovarian carcinoma.Methods:IFO 2.0 in 500 ml normal saline day 1—5, VP16 100 mg in 500 ml normal saline d1,3,5 Results:The overall response rate was 38.5%, mylosuppression and alopecia were the most common toxicities. Leukopenia rate was 71.4%, alopecia rate was 100%, gastro intestinal and nervous toxicity were mild. Conclusions:Combination of IFO and VP16 was very effective on relapse ovarian carcinoma with mild toxicity and should be widely used.

Objective To observe the effects of elevated temperatures(37~44.5℃)on the cell counts, hemolysis and osmotic fragility of stored red blood cells.Methods After 7~35 days of storage at 4℃, erythrocyte suspensions were heated by incubation at 37℃ and 44.5℃ for 30 min in an incubator and then examined for cell counts, hemolysis and osmotic fragility.Results Red blood cell, white blood cell and platelet counts, hemoglobin and potassium were unchanged following the heat treatment. In the osmotic fragility test, hemolysis remained within normal limits. Hemolysis of groups incubated at 37℃ and 44.5℃ began at (4.41?0.38)g/L and (4.3?0.2)g/L respectively while a complete hemolysis occurred at (3.42?0.36)g/L and (3.4?0.1)g/L , showing no significant difference compared to the room temperature control (4.5?0.18)g/L and (3.6?0.1)g/L. There was no significant distinction in the proportions of smooth spherocyte among the samples incubated at different temperatures, except the samples stored for 35 days, probably due to the long storage period.Conclusions Heating at temperatures between 37～44.5℃ for as long as 30 min does not cause hemolysis or other damage to red blood cells.

Optic nerve is composed by the axonal of retinal ganglion cells,there are no Schwann cells around it,and optic nerve belongs to the central nervous,so it cannot regenerate when injuried. In 1985 So and Aguayo have made a success in peripheral nerve retinal transplant,which completely changes the concept that optic nerve injury cannot regenarate. Currently nerve injury recovry has following several methods: use of neurotrophic factor,such as nerve growth factor,ciliary neurotrophic factor and brain-derived neurotrophic factor,etc. These factors could promote the regeneration and repair of retinal ganglion cells; treatment of gene correction and gene regulation,by changing the expression of host gene,reduce the effect due to the disease,slow the progress of the disease course or provide protection against the disease; neural stem cell transplantatin and tissue-engineered Schwann cell transplantion. But these treatments are still at the stage of animal experiment,how timely and effctively reduce the apoptosis and increase the survival rate of ganglion cells,even further promote nerve regeneration and recovery,there is still not a perfect method so far.

BACKGROUND:Preadipocyte is a kind of specific precursor cells with the potential of proliferation and differentiation into adipocytes.If factor or drug with strong promotion of preadipocyte proliferation and differentiation is obtained and used in adipose tissue transplantation,which could elevate transplantation outcome of adipose tissues.OBJECTIVE:To find an optimal culture environment and to accumulate culture experience of in vitro culture 3T3-L1 preadipocytes,and to observe the effect of insulin-like growth factor(IGF)-1 on the proliferation and differentiation of 3T3-L1 preadipocytes,and to explore the optimal concentration of IGF-1.DESIGN,TIME AND SETTING:The cell control observation was performed at the Science Experiment Center,Liaoning University of Traditional Chinese Medicine from October 2007 to February 2008.MATERIALS:3T3-L1 preadipocytes were purchased from Shanghai Institutes For Biological Sciences.IGF-1 was bought from Biological,USA.METHODS:According to in vitro culture direction of 3T3-L1 preadipocytes,3T3-L1 preadipocytes were divided into 6 groups.3T3-L1 preadipocytes in the blank control group were inoculated in high-glucose DMEM supplemented with 0.1 volume fraction of fetal bovine serum.3T3-L1 preadipocytes in each experimental groups were respectively treated with high-glucose DMEM containing 5,10,20,50,100 ?g/L IGF-1 and 0.1 volume fraction of fetal bovine serum.MAIN OUTCOME MEASURES:Growth,proliferation and differentiation of 3T3-L1 preadipocytes in each experimental groups under the inverted microscope,and photographed.When cells were confluence,cell cycles were detected by flow cytometry.Growth rate of 3T3-L1 preadipocytes was measured by MTT essay.Fat growth rate in 3T3-L1 preadipocytes were examined by using oil red O stained-extracted assay.RESULTS:Inverted microscope showed that 3T3-L1 preadipocytes before differentiation were fusiform shape,with little fat in their endochylemas.3T3-L1 preadipocytes after differentiation were spherical shape,with much fat in their endochylemas.Lipid droplet gathered in the perinuclear space,and was stained orange by oil red O stained-extracted assay,forming ring-shape.Results from MTT essay and oil red O stained-extracted assay demonstrated that growth rate of 3T3-L1 preadipocytes and fat growth rate in 3T3-L1 preadipocytes were higher in each experimental groups treated with different doses of IGF-1 compared with the blank control group(P

Objective:To investigate the effect of cPLA 2(cytosolic PLA 2, 85-kD PLA 2) on the signaling pathways of IL-1?、IL-6 release in LPS induced Hela cells.Methods:①LPS stimulated Hela cells were exposed to the complex of cPLA 2 initiation site-directed antisense oligonucleotide and liposome in the indicated doses and time, and then,analyzed the changes of cPLA 2 both in mRNA and in protein by RT-PCR and Western blot.②At the same time, the supernatants were collected to detect the level of IL-1? and IL-6 under radioimmunoassay(RIA).Results:①The transfection led to a dose-dependent decrease in cPLA 2 protein, while the change of mRNA is not notable.②The levels of IL-1?、IL-6 in the transfected cells were reduced following the repression of cPLA 2 compared with that of LPS added only.Conclusion:cPLA 2 probably plays an important role in the signaling mechanisms on IL-1?、IL-6 release in LPS-induced Hela cell.
