With improvement in stent designs, the practice of direct stenting (DS) without balloon predilation has become more widespread. DS may allow partial retention of endothelium within treated arteries, and associate with decreased utilization of contrast agent, number of catheter, exposure of X-ray,and expense. This paper evaluate the experiment base, principle, indication, contraindication, skills, complications as well as the result of acute and chronic follow up of DS.

Objective To investigate the correlation between abnormal lipid metabolism and coronary artery lesions. Methods Two hundred and sixty seven patients were devided into the control group ( n =101) and the coronary heart disease (CHD) group ( n =166), which included single vessel lesion ( n =54), double vessel lesions ( n =68) and triple vessel lesions ( n =44) according to coronary angiography. At the same time the lipid components were examined and the ralationship between serum lipid level and coronary artery lesions were analysed. Results Compared with the control, the total cholesterol (TC), low density lipoprotein cholesterol (LDL-C) and triglyceride (TG) level were significantly elevated while but high density lipoprotein cholesterol (HDL-C) was lowered in the CHD group. The severity of coronary lesions was increased with the elevation of TC, LDL-C, apolipoproteinB (ApoB), TC/HDL-C, LDL-C/HDL-C, and the reduction of HDL-C. There were significant differences in terms of lipid level beteewn the CHD group and the control. The analysis showed that TC/HDL-C and LDL-C/HDL-C were most directly correlated with the coronary artery lesions in the CHD group. Conclusion The results suggest that the severity of coronary artery lesions correlated with abnormal lipid metabolism, and LDL-C/HDL-C, TC/HDL-C are better indicators than other lipid components.

Objective To evaluate the nutrition status and the prognosis of acute stroke patients with hy-pothyroidism during hospitalization. Methods The clinical data of 28 acute stroke patients with hypothyroidism (study group) and 28 stroke patients with normal thyroid function (control group) were retrospectively analyzed.Results After (10±4) days of hospitalization, hemoglobin and serum albumin levels in study group significantlydecreased ( P < 0. 05 ). The requirement of calories and protein, incidence of pulmonary infections, alimentarytract hemorrhage and diarrhea, and hospital stays were significantly higher in study group than in control group (P < 0. 05 ). Conclusion The nutrition status is poor in acute stroke patients with hypothyroidism, who were more easier to be suffered from clinical complications and worse prognosis.

Hydrogen sulfide (H2S) was considered as the third gasotransmitter,along with nitric oxide and carbon monoxide,with extensively biological activities.Considerable evidence showed that H2S was involved in inflammatory processes such as in inflammatory cells,inflammatory mediates,vascular tension and signaling pathways.Previous studies suggested H2S played a bidirectional role in regulating inflammation including pro- and anti-inflammatory actions due to different animal models.Further study about the role and mechanism of H2S in inflammation will contribute to efficient prevention and treatment for inflammatory diseases.
