Objective To investigate the changing of endothelial progenitor cells and nitric oxide in patients with pulmonary arterial hypertension secondary to chronic obstructive pulmonary disease.Method Mononuclear cells from 20 healthy persons (the control group, n = 20) , COPD patients without PAH (COPD non-PAH group, n =30) and patients with PAH secondary to COPD (COPD and PAH group, n=30) were investigated. Total mononuclear cells were isolated from peripheral blood by Ficoll density gradient centrifugation. EPC number and migration were assayed by colony forming unit-EPCs (CFU-EPCs) assay and modified Boyden chamber assay , respectively. EPC adhesion assay was performed by replanting those on fibronectin-coated dishes , then adherent cells were counted. The concentration of NO was measured with method of nitrate reductase.Result The numbers of CFU and migration, adhesion activity of circulating EPCs in COPD[ (21.9±3. 9)CFU-EPC] and PAH group[ (14. 2 ±3. 5)CFU-EPC] were significantly lower than that in non-COPD group and COPD non-PAH group [ ( 24.9 ±4.1) CFU-EPC ]. It was also observed that a strong negative correlation between the levels of PAH and the numbers of CFU and adhesion, migration activity of circulating EPCs. The NO level in the PAH group [ (43. 6 ±4. 8)ng/ml] was significantly lower than that in control group [ ( 67. 17±4.9 ) ng/ml ] ( P < 0.01). The NO level was positively correlated with number and migration ability of EPCs( r =0. 77,0.71, P <0.01) , but not correlated with adhesion ability.Conclusion The number of CFU and migratory, adhesive activity of EPC in patients withPAH secondary to COPD was significantly decreased. These changes may be associated with low level of plasma NO.

Objective To detect the changes of cerebral perfusion in patients with MELAs syndrome by using MR perfusion technique.Methods Thirteen patients with MELAS syndrome and 13 controls with normal neurological conditions were scanned with the sequence of flow-sensitive alternating inversion recovery exempting separate T1 measurement(FAIREST).Their rCBF values were obtained in regions of bilateral basilar nuclei and thalami,as well as bilateral temporal lobes and occipital lobes.Regression analysis was carried out to determine the effect of location and side on the measurement of rCBF in controls.One-way ANOVA was conducted to compare rCBF values among the control group.the lesion ROIs and normal ROIs of the MELAS syndrome group.Results The values of rCBF were 0.83±0.23,1.17±0.30.0.93±0.28,and 1.11±0.25 for the left basilar ganglia,thalamus,temporal lobe,and occipital lobe respectively,while they were 0.77±0.15,1.03±0.34,1.06±0.23,and 1.09±0.23 for the right basilar ganglia,thalamus,temporal lobe.and occipital lobe respectively.Regression analysis revealed no effect of location and side on the rCBF (P＞0.05).The rCBF value for control group was 1.00±0.28,while it was 1.01±0.31 for the normal ROIs and 1.95±0.43 for the lesion ROIs in the MELAS syndrome group(F=54.99.P＜0.01).The rCBF of the lesion ROIs in the MELAS syndrome group was significantly higher than the normal ROIs and the control group.Conclusion CBF maps can reveal changes of cerebral blood flow in patients with ietal MELAS,which suggests increased perfusion in the stroke-like lesions.

Objective:Based on relevant database data analysis,to explore the correlation of the abnormal expression of EMT related factors and chronic obstructive pulmonary disease and its related non-small cell lung cancer.Methods: Based on some data sets of GEO in the NCBI database,to perform express analysis,survival analysis and correlation analysis.Results: ①Snai1 and other EMT related regulatory factors exist significantly higher expression in non-small cell lung cancer patients,and E-cadherin (CDH1) was showed significantly lower expression. ②A large number of COPD patients samples were analyzed,and some EMT-related molecules in patients with COPD also showed significant abnormal expression and consistented with the changes in patients with non-small cell lung cancer.Conclusion: The results showed that dysregulation expression of EMT related regulatory factors may have some correlation with disease progression of COPD patients through the EMT markers and their expression and correlation analysis in COPD patients.

Objective To study the value of MSCT angiography(MSCTA)in diagnosing lower extremities arterial disease (LEAD) of diabetic foot ulcers and analyze the possible influential factors on the onset of diabetic foot ulcers.Methods 80 diabetic patients for MSCTA examination were divided into two groups by whether combined with foot ulcers.The tibial artery calcification score (TACS) and peripheral arterial occlusion index (PAOI) were calculated and the possible risk factors of diabetic foot ulcer were analyzed.Results There were 30 cases suffered with foot ulcer and 18 cases occurred lower extremity arterial occlusion (LEAO), the average PAOI was 4.40(3.60, 5.75).Non-foot ulcer cases were 50, and there were 8 cases suffered with LEAO, the average PAOI was 2.05(1.43, 3.10).Compared to patients without foot ulcer, patients with foot ulcer were older, had a lower BMI, and were more likely to have a history of tobacco use.They usually had higher TACS and severer peripheral arterial occlusive disease (PAOD).Stepwise regression model showed that foot ulcers had significant correlation with TACS and PAOI.Partial correlation analysis showed TACS was independent from PAOI in impacting diabetic foot ulcer.Conclusion MSCTA has important clinical value in diagnosing and valuing diabetic foot ulcer LEAD.Age, smoking history,BMI,TACS and PAOI affect the incidence of diabetic foot ulcers, and TACS and PAOI are the independent risk factors for diabetic foot ulcers.

Objective To study the anti-tumor effect of Zhongjiefeng Injection in vitro and its combination with adriamycin.Methods MTT assay was adopted to determine the in-vitro anti-tumor effect,IC50 was used to measure the direct anti-tumor effect,and Jing' s formula was applied to analyze the combination of the drugs.Results Zhongjiefeng Injection can inhibit the proliferation of Bel 7402(human hepatoma cells),HCT-8(human colon cancer cells),and the IC50 was 33.13 mg/mL for Bel 7402 and 52.39 mg/mL for HCT-8 respectively.Zhongjiefeng Injection at the concentrations of 3.125,6.25,12.5 mg/mL showed an efficancy potentiation action with doxorubicin on the inhibition of HCT-8 cells in vitro,and 25,50 mg/mL showed a synergic effect on HCT-8 .Conclusion Zhongjiefeng Injection has a certain in-vitro inhibitory effect on the growth of Bel 7402 and HCT-8,its combination with doxorubicin in vitro can produce synergic effects(a simple combined or enhanced effects)to HCT-8 cells,especially high concentrations of Zhongjiefeng Injection with doxorubicin.It is suggested that Zhongjiefeng Injection in the doubled dosage may have a better synergistic effect with doxorubicin in clinical treatment of colon cancer.
