Objective: To assess therapeutic effect of alprostadil on improving myocardial microcirculatory disturbance and hemorheological disorder in patients with coronary heart disease (CHD).Methods: A total of 164 CHD patients treated in our hospital were selected.According to random number table method, they were randomly and equally divided into routine treatment group and alprostadil group (received alprostadil injection based on routine treatment group), both groups were treated for two weeks.Serum levels of nitric oxide (NO), vascular endothelial growth factor (VEGF), thromboxan β2 (TXβ2) and hemorheological indexes were measured and compared between two groups after treatment;TIMI grade and TIMI myocardial perfusion grading (TMPG) of CAG were compared between two groups after treatment.Results: Compared with routine treatment group after treatment, there were significant rise in serum levels of NO[(64.9±10.3) mmol/L vs.(98.8±13.2) mmol/L]and VEGF[(1.62±0.53) mg/L vs.(3.31±0.68) mg/L], and significant reduction in serum TXβ2 level[(180.4±22.8) pg/ml vs.(78.9±9.6) pg/ml], P<0.05 or<0.01;significant reductions in whole blood high shear viscosity[(5.84±0.72) mPa·s vs.(4.25±0.31) mPa·s], whole blood low shear viscosity[(8.42±0.93) mPa s vs.(5.31±0.68) mPa s], plasma viscosity[(2.73±0.34) mPa s vs.(1.61±0.29) mPa s], fibrinogen level[(4.09±0.55) g/L vs.(3.13±0.55) g/L], erythrocyte aggregation index[(3.85±0.47) vs.(2.24±0.31)]and maximum platelet aggregation rate[(67.4±5.3)% vs.(48.0±3.6)%]in alprostadil group, P<0.05 all.Among those patients undergoing second CAG, compared with routine treatment group, there were significant reductions in percentages of TIMI and TMPG grade II and grade III, and significant rise in percentages of TIMI and TMPG grade 0 and grade I in alprostadil group, P<0.05 or <0.01.Conclusion: Alprostadil can significantly improve myocardial microcirculatory disturbance and hemorheological disorder in patients with coronary heart disease, which is worth extending.

Objective To investigate the relationship between C-reactive protein (CRP) and carotid intima-media thickness in pa-tients with impaired glucose tolerance (IGT). Methods Senan CRP was measured with immunoturhidimetry and the carotid intima-media thickness (CAIMT) was measured using color Doppler in 108 patients with impaired glucose tolerance (IGT) and 80 subjects with normal glucose tolerance(NGT).Then we observed all IGT patients for 3 years using prospective follow-up method, Oral Glucose tolerance test (OGGT) and every index were measured in follow-up 1.5 year and 3 year. Results 2 objects were lost to follow-up. IGT group showed a significant higher CAIMT and CRP compared with NGT group. After follow-up 1.5 year and 3 year, the patients with impaired glucose toler-ance (IGT) were divided into type 2 diabetes (T2DM) group and IGT group based on the level of blood glucose. Both T2DM group and IGT group showed a significant higher CAIMT and CRP, compared with NGT group. The level of serum CRP of T2DM group was higher than that of IGT group, and the level of serum CRP of IGT group was higher than that of NGT group. There were great differences between each group.Linear correlation showed that the level of blood glucose was positively correlated with CRP and CAIMT in T2DM group after follow-up 3 year. CAIMT was positively correlated with the level of blood glucose and CRP. Mulfivariant stepwise regression showed that CRP was signifi-canfly correlated with the level of blood glucose and CAIMT. Conclusion Inflammation played an important role in the development of dia-betes, and it had great vessels complication. The patients with impaired glucose tolerance, who have high level of CRP, were facilitated to be diabetes, and they were at risk of getting great vessels complication during the phase of impaired glucose tolerance. So it would be helpful to prevent IGT patients with high CRP or CAIMT with anti-inflammatory therapy.

Objective To study the relationships between airway inflammation,reticular basement membrane (RBM) thickness and bronchial hyperresponsiveness (BHR) before and after treatment with inhaled corticosteroids (ICS) in patients with asthma.Methods Twenty-eight patients with asthma (asthma group) were treated with inhaled budesonide (200 μg,twice a day for 12 months).Lung function,bronchoalveolar lavage (BAL) fluid and airway biopsy pathology were carried out before and after treatment.And 10 patients without asthma were acted as control group.Results BAL fluid eosinophils,epithelial cell and mast cell proportions before treatment in asthma group were significantly higher than those in control group [asthma group:(1.60 ±0.11)％,(2.50 ±0.29)％,(0.1100 ±0.0100)％ ;control group:(0.50 ±0.02)％,(1.20 ±0.08)％,(0.0200 ±0.0001)％,P ＜0.01].RBM and smooth muscle thickness were increased in asthma group than those in control group [ asthma group:( 14.25 ± 2.15 ),(0.36 ± 0.01 ) μ m;control group:(4.45 ± 1.22),(0.20 ± 0.01 ) μ m,P ＜ 0.01 ].BAL fluid eosinophils,epithelial cell and mast cell proportions,RBM and smooth muscle thickness decreased after treatment in asthma group [ (0.80 ±0.04)％,(1.60 ±0.07)％,(0.0500 ±0.0020)％,(6.18 ± 1.30) μm,(0.26 ±0.02) μm,P ＜0.01].RBM thickness was negative correlation with methacholine provoking dose which made forced expired volume in one second reduce by 20％ (r =-0.672,P ＜ 0.01 ).Conclusions Airway inflammation,RBM thickness and BHR in patients with asthma are interrelated and improved with ICS.The results of this study support the need for early and long treatment with ICS.

The immune effect of two recombinant protein fragments of spike protein in severe acute respiratory syndrome coronavirus (SARS CoV) was investigated in Balb/c mice. Two partial spike gene fragments S1 (322 1464 bp) and S2 (2170 2814 bp) of SARS coronavirus were amplified by RT-PCR, and cloned into pET-23a prokaryotic expression vector, then transformed into competent Escherichia E. coli BL21 (DE3)(pLysS) respectively. Recombinant proteins were expressed and purified by Ni2+ immobilized metal ion affinity chromatography. The purified proteins mixed with complete Freund adjuvant were injected into Balb/c mice three times at a two-week interval. High titer antibody was detected in the serum of immunized Balb/c mice, and mice immunized with S1 protein produced high titer IgG1, IgG2a, IgG2b and IgG3, while those immunized with S2 protein produced high titer IgG1, IgG2a, but lower titer IgG2b and IgG3. Serum IFN-concentration was increased significantly but the concentrations of Il-2, IL-4 and IL-10 had no significant change. And a marked increase was observed in the number of spleen CD8+ T cells. The results showed that recombinant proteins of SARS coronavirus spike protein induced hormonal and cellular immune response in Balb/c mice.
