Objective:To explore feature of clinic and coronary angiography (CAG)of acute myocardial infarction (AMI)for young adults less than 30 years old.Methods:A total of 41 AMI patients,who were under 30 years old and hospitalzed in our hospital from 2004 to 2012,were enrolled as young group.Another 360 AMI patients >50 years were randomly selected as middle-aged group during the same time.Clinical features and CAG results were compared between two groups.Results:Compared with middle-aged group,there were significant rise in percenta-ges of male (68.1% vs.97.6%),smokers (50.6% vs.80.5%)and hypercholesterolemia (59.2% vs.65.9%)and body mass index [(22.3±6.6)kg/m2 vs.(26.3±9.6)kg/m2 ],and significant reduction in percentages of hyper-tension (63.1% vs.24.4%)and diabetes mellitus (30.6% vs.4.9%)in young group,P<0.05 or <0.01;for ex-citing cause,percentages of psychological factors such as tension and anxiety (29.3% vs.3.6%),staying up late (39.0% vs.2.8%)and heavy drinking (14.6% vs.4.7%)in young group were significantly higher than those of middle-aged group,while percentages of agitation (8.3% vs.0)in middle-aged group was significantly higher than that of young group (P<0.05 or <0.01).For CAG results,young group was mainly single vessel coronary disease (56.1%),which were mainly type A (53.7%)and type B1 (29.3%)lesions,while middle-aged group was mainly multi-vessel coronary disease (48.1%),which were mainly type B2 (29.7%)and type C (33.9%)lesions,and there were significant difference between two groups (P<0.05 or <0.01).Conclusion:Smoking,obesity and hy-perlipidemia are the most important risk factors for acute myocardial infarction;the major exciting causes are sta-ying up late,alcohol drinking and high mental stress etc.in young AMI patients;their coronary lesions are mainly single vessel coronary disease,and of type A and type B1 .

Objective To explore the role of interleukin-8(IL-8) in the pathogene sis of COPD MethodsRat model of chronic obstructive pulmonary disease(COPD) was established by exposure Wistar rats to cigarette smoke dai ly for 120 days Total cell counts and neutrophil counts in BALF were examined The levels of IL-8 and tumor necrosis factor-?(TNF-?) in BALF and serum wer e measured with ELISA Lung tissue section stained by HE was observed to study t he morphological alternations and MLI,MAN and PAA were measured Result sMLI and PAA in COPD rat were higher than those in control group (P

Objective To study the effect of red cell and plasma protein parameters on progression, prognosis and recurrence of cerebral infarction. Methods Clinical data from 105 patients with cerebral infarction were analyzed. The pa?tients were divided into four paired groups:progressive stroke group and complete stroke group, short-term favorable progno?sis group and short-term unfavorable prognosis group, long-term favorable prognosis group and long-term unfavorable prog?nosis group, relapsed cerebral infarction group and not relapsed group by different criterion. The red cell and plasma protein parameters were compared between groups. Results There were significantly higher mean corpuscular volume(fL:85.92± 4.50 vs 83.79±4.64,t=2.164,P<0.05), red cell distribution width(fL:13.50±2.45 vs 11.90±2.90,t=2.694,P<0.01), globu?lin(g/L:27.46±4.33 vs 24.79±4.03,t=3.029,P<0.01)and lower albumin(g/L:39.00±3.86 vs 42.89±4.45,t=4.242,P<0.01)in progressive stroke group than those of complete stroke group. The elevated red cell distribution width, reduced albu?min were the risk factors of progressive stroke. In the short-term unfavorable prognosis group, red cell distribution width was significantly higher than that in short-term favorable prognosis group(fL:13.90 ± 2.45 vs 12.00 ± 2.12,t=2.905,P<0.01). The red cell distribution width was positively correlated with mRS scores assessed 3 months and 18 months after cerebral in?farction(P<0.01). Conclusion Progressive stroke rate increases in cerebral infarction patients with elevated red cell distri?bution and reduced albumin;Red cell distribution width has a certain reference value for forecasting the prognosis of cere?bral infarction .

Objective To evaluate the advantages and disadvantages of various methods for the treatment of aortic dissection involving aortic arch. Methods The clinical data of 56 patients with aortic dissection involving aortic arch were analyzed retrospectively. All the patients were treated with throacic endovascular aortic repair (TEVAR) combined with chimney technique and hybrid operation to reconstruct partial vessels of the aortic arch according to the different morphology sites of aortic disease. Results Among 56 patients, 29 cases received TEVAR combined with chimney technique of left subclavian artery, and 27 cases received TEVAR combined with hybrid operation. Six cases had typeⅠendoleak. Among them, 2 cases improved by compliant balloon dilatation, and 4 cases were not treated. There was no death in perioperative period. The patients were followed up for 3-70 (22 ± 3) months, and all the branches of the artery were unobstructed during middle and long term follow-up. Conclusions Combined endovascular treatment is a safe and effective method for aortic dissection involving the aortic arch. In the meantime, strict preoperative evaluation and suitable operation method is also important.

Purpose:To investigate the clinical feature of small-cell esophageal carcinoma,and try to find rational combined therapy modality.Methods:A retrospective study was conducted in a total of 11 cases of small cell esophageal carcinoma hospitalized from 1990 to 1999 and the literature of small cell esophageal carcinoma in recent years were re- viewed.Results:The median survival time of these patients is 11 months,five cases survived over 1 year,the 1 yr survival rate is 45.45%;only one patient survived over 3 years;nine cases received multimodality treatment,the median survival time was 12 months,and of which,the median survival time of the seven patients treated with combined regimens including surgical operation was 15 months,and the survival time was 10 months and 7 months respectively in two patients treated with combined regimens not including surgical operation.one patient underwent surgery alone,the survival time was 5 months;one patient received chemotherapy alone and survived 6 months.Conclusions:Small cell esophageal carcinoma has a poor prognosis.multimodality treatment including chemotherapy is an effective approach in improving survival;surgical operation play an important role which can not be replaced and preoperative chemotherapy combined with surgical resection and postoperative chemotherapy may be a better combined treatment modality in local regional small cell carcinoma of e- sophagus.

Objective To establish a rat model of pulmonary hypertension induced by left-to-right shunt and explore the influence of high pulmonary blood flow on pulmonary vascular collagen remodeling.Methods Abdominal aorta and inferior vena cava shunting was produced in rats. Pulmonary artery meanpressure (PAMP) of each rat was measured by using a right cardiac catheterization.Pulmonary artery collagen Ⅰ and Ⅲ were detected using immunohistochemisty.Results After 11 weeks of shunting the Qp/Qs was 3.3∶1.0,indicating a large shunt. Pulmonary artery mean pressure was increased as compared with controls[(23.0?0.9) mm Hg vs (15.7? 1.1) mm Hg,P

Objective To explore the clinical diagnosis and treatment of cyclic vomiting syndrome in children.Methods Thirty children proved with cyclic vomiting syndrome admitted from January,1998 to January,2003 were analyzed retrospectively.Results Cyclic vomiting syndrome was most likely to occur in 3-12 years old.The male to female ratio was 3∶2.The clinical manifestations were recurrent vomiting.Twenty-one cases had inducements,while 9 cases had not inducements.It was safe and efficient that curing cyclic vomiting syndrome with cyprohetadine and amitriptyline.Conclusions If these children with cyclic vomiting syndrome are inefficient to treatment,excluding metabolizable diseases,gastrointestinal,neurological diseases,they may be diagnosed cyclic vomiting syndrome,and cured with cyprohetadine and amitriptyline.
