ObjectiveTo study the effect of Shuanglong pill on expression of vascular endothelial growth factor(VEGF) and basic fibroblast growth factor(bFGF) on aortic atherosclerotic plaque.MethodsAs atherosclerotic(AS) models of rabbits were made by immune injury plus hyperlipid diet, all rabbits were divided into blank control group(group Ⅰ,6), experimental control group(group Ⅱ, 6), captopril control group(group Ⅲ, 6; 10 mg/kg·d,12 weeks), and Shuanglong pill group(group Ⅳ, 6; 2.52 g/kg·d,12 weeks). Quantitive and qualitative analysis of expression of VEGF and BFGF on aortic atherosclerotic plaque were performed.ResultsExpressive area, density and density index of VEGF and bFGF on aortic atherosclerotic plaques were significantly decreased in group Ⅲ and Ⅳ than in group Ⅱ(P<0.01). There were significant decrease for VEGF expression in group Ⅳ than in group Ⅲ(P<0.01).Pathologic staining showed that there were no foam cells formation and no stained yellow in group Ⅰ, but mass foam cells formation and widespread stained yellow in group Ⅱ. There were a small quantity of foam cells formation and little stained yellow in group Ⅲ and group Ⅳ.ConclusionShuanglong pill can delay/reverse AS progression by inhibiting VEGF and bFGF expression in atherosclerotic plaque as well as captopril.

OBJECTIVETo observe therapeutic effect of photoelectric treatment instrument on simple obesity.

METHODSSixty cases of simple obesity were randomly divided into two groups, 30 cases in each group. The treatment group were treated with photoelectric treatment instrument combined with acupuncture, i.e. after acupuncture, the electrodes of XS-998A photoelectric treatment instrument were placed at points of the abdomen, with the laser out-put head on Shenque (CV 8), Shuifen (CV 9) or the parts with much fat, or close to the liver area for the patient of fat liver. The control group were treated with routine acupuncture alone. Changes of main symptoms and signs, and BMI before and after treatment were investigated in the two groups.

RESULTSThe symptoms and signs, and BMI were more significantly improved in the treatment as compared with the control group with a significant difference between the two groups (P < 0.05).

CONCLUSIONAcupuncture combined with laser radiation at the relative area on the abdomen can increase the therapeutic effect on obesity.

Objective To detect the expression levels of interleukin (IL)-32 and tumor necrosis factor (TNF)-α in peripheral blood of rheumatoid arthritis (RA) patients,and analyze the relations between IL-32 and level of erythrocytes (ESR),creactive protein (CRP),rheumatoid factor (RF),the disease activity index 28 (DAS28) scores in RA patients.The aim of this study is to identify the clinical significance of IL-32 in RA patient.Methods We collected 97 specimens of peripheral blood from RA patients,including 36 RA patients with high active disease,33 RA patients with moderate active disease,28 RA patients with stable disease,36 non-RA connective tissue diseases (CTD) patients and 30 healthy volunteers.The mRNA levels of IL-32,TNF-α in the peripheral blood mononuclear cells (PBMC) were determined by quantitative real-time PCR (QRT-PCR).The concentration of IL-32,TNF-αt in plasma were detected by enzyme linked immunosorbent assay (ELISA),one-way AN OVA and Spearman's corrclation and multiple linear regression were adopted for statistical analysis.Results ①The mRNA levels of IL-32 and TNF-α in active RA patients were higher than those in healthy control group (0.29±0.07,0.24±0.06 vs 0.11±0.06 for IL-32 in the high active RA group and moderate active RA group versus the healthy group; and 0.042±0.022,0.012±0.006 vs 0.004±0.002 for TNF-α in the high active RA group and moderate active RA group versus the healthy group,P＜0.01),and than those in stable RA patients,and non-RA CTD patients.There was no significant difference among the stable disease groups,healthy control group and non-RA CTD group in the level of mRNA.② The concentration of IL-32,TNF-α in the plasma of RA patients with active disease was higher than that of healthy control group [(107±42) pg/ml,(66±27) pg/ml vs (20±10) pg/ml for IL-32 in the high active RA group and moderate active RA group versus the healthy group; and (261±77) pg/ml,(186±84) pg/ml vs (72±20) pg/ml for TNF-αt in the high active RA group and moderate active RA group versus the healthy group,P＜0.01].③ The expression levels of IL-32 was positively correlated with the level of TNF-α,ESR,CRP,RF,DAS28 scores in the plasma of RA patients (r=0.568,0.321,0.185,0.325,0.303 respectively,P＜0.01).④ The expression levels of IL-32 was positively correlated with the level of TNF-α (the regression coefficients and P values were b=1.721,P＜0.01 and b=0.176,P＜0.01 respectively).Conclusion The levels of IL-32 in peripheral blood may be used as an indicator for disease activity of RA.

In the reductive branch, glycerol is first dehydrated to 3-hydroxypropionaldehyde that is then reduced to 1,3-PD under the consumption of reducing power (NADH). If over-expression of the gene dhaB encoding glycerol dehydrase is achieved,the reducing power will be scarce and 3-hydroxypropionaldehyde will be accumulated,which is disadvantage to produce 1,3-propanediol.The structure gene yqhD from E.coli encoding 1,3-propanediol oxidoreductase isoenzyme[under the consumption of reducing power (NADPH)]and the gene dhaB encoding glycerol dehydrase from Klebsiella pneumoniae was amplified using PCR method.The two gene were transferred into expression vector pEtac to construct a novel recombinant Klebsiella pneumoniae (pEtac-dhaB-tac-yqhD).Over-expression of yqhD and dhaB in Klebsiella pneumoniae was achieved with pEtac-dhaB-tac-yqhD.The fermentation result on aerobic conversion showed the increase of 20% of 1,3-propanediol yield by Klebsiella pneumoniae(pEtac-dhaB-tac-yqhD) was obtained compared with Klebsiella pneumoniae.The main by-products,acetic acid and butanediol decreased estrogen receptors 30% obviously.

Objective:To explore clinical and histopathological characteristics of primary biliary cirrho-sis-autoimmune hepatitis overlap syndrome.Methods:Clinical data and pathological findings of 10 pa-tients were reviewed.Results:Serum glutamine transpeptidase,alkaline phosphatase levels,alaninetransaminase,aspartate transaminase,serum IgG and IgM were elevated in all the patients.They were allpositive for anti-mitochondrial antibody and AMA-M2.Nine patients were positive for anti-nuclear anti-body and one patient was positive for anti liver-kidney microsome antibody.Liver biopsies in these pa-tients revealed:ten patients had bile duct lesion,hepatitis activities ranged from moderate to severe,andfibrosis ranged from S1 to S3.Conclusion:PBC-AIH overlap syndrome is mostly found in middle-agedwomen.It has the clinical and histopathological characteristics of both PBC and AIH.Accurate andprompt diagnosis of overlap syndrome patients should be based on the clinical presentation,biochemicaland immune indexes,and hepalic pathological changes.

Objective To study the dynamic changes of pulmonary lesions of severe acute respiratory syndrome(SARS)treated by non-invasive positive pressure ventilation(NIPPV)on CT. Methods Serial chest CT images in 18 patients with SARS were retrospectively analyzed before and after NIPPV(4—12 days),and a long-term follow-up(3—36 months)examination by CT was carried out.And 27 SARS cases without NIPPV were enrolled as the control group.Results(1)There were dynamic changes in 15 cases of 18 cases:partial multilobar consolidations of bilateral lungs changed into ground-glass opacities in 7 of 18 cases,a circular pulmonary emphysema around bronchial vascular strains of the lower lobes was seen in 5 of 18,subpleural pulmonary emphysema was seen in 8 of 18,pulmonary barotraumas were showed in 2 of 18.Residual of subpleural curvilinear shadow related to NIPPV was found in 2 cases on the follow-up scan.(2)Above changes on CT were not found in 27 cases without NIPPV.Conclusion There were changes of pulmonary lesions of SARS on CT related to NIPPV treatment,It is beneficial to assess the CT images in the NIPPV treatment of the related pneumonia in SARS.
