ABSTRACT

Objective:To investigate the clinical characteristics and therapeutic methods of coronary artery aneurysm (CAA).Methods:The clinical data and coronary angiography of 32 patients confirmed by coronary angiography as coronary aneurysm in Shenzhen Hospital of Southern Medical University and Shenzhen People′s Hospital were collected. They were followed up, and the different therapeutic methods were analyzed.Results:Thirty-two cases (1.8%) of coronary artery aneurysms were found in 1 778 patients undergoing coronary angiography. The main sites of coronary ectasia were right coronary artery, anterior descending branch and circumflex branch, and the left main branch was rare. Among the patients with coronary artery aneurysms, there were 25 patients with coronary artery stenosis. All the 32 patients were given anticoagulant, antiplatelet, improvement of coronary spasm and statin therapy, among whom 2 patients were treated with stent implantation and 6 patients were treated with coronary artery bypass graft (CABG) and ligation of coronary aneurysm. During the follow-up (average 15 months) of 1 patient, acute myocardial infarction reoccurred, and coronary angiography indicated that the stenosed coronary segments after artery ectasia was occluded because of thromboembolism. In the remaining patients, there were no major cardiovascular events such as angina pectoris, acute myocardial infarction and sudden cardiac death.Conclusions:Coronary artery aneurysm is not a rare heart disease. Coronary thromboembolism, thrombosis and vasospasm are the main causes of angina pectoris and myocardial infarction. Anticoagulant, antiplatelet, antispasmodic drugs and suitable coronary artery bypass can significantly improve the clinical prognosis of patients with coronary artery aneurysm.

ABSTRACT

Objective:To explore the expression of IL-22 in the patients with rheumatoid arthritis,and to define the clinical sig-nificance of IL-22 cells for RA. Methods: A total of 50 RA patients, 15 OA patients and 15 healthy controls were enrolled. The proportion of Th22 cells in peripheral blood and synovial fluid( SF) of RA patients was detected by flow cytometry;the levels of IL-22 in serum and synovial fluid of RA patients were detected by ELISA. The clinical parameters of disease activity were assessed including ESR,RF,CRP,DAS28,anti CCP and the degree of bone erosions determined by X-rays. Pearson correlation analysis,t test and Kruskal-Wallis H test were used for statistical analysis. Results:The proportion of Th22 cells in RA patients was higher than that of OA patients (t=2. 290 ,P=0. 021) and healthy controls(t=2. 524,P=0. 015). IL-22 levels in RA patients were higher than that of OA patients (t=2. 560,P=0. 014) and healthy controls(t=2. 768,P=0. 009). IL-22 in the RF positive group were higher than that of RF negative group(t=2. 322,P=0. 035). IL-22 in the anti-CCP antibody positive group were higher than that of anti-CCP antibody negative group (t=2. 504,P=0. 015). The levels of IL-22 were correlated positively with ESR,RF,DAS28(r=0. 312,0. 314,0. 332,P χ20.05(3),P<0. 05). Serum IL-22 levels in the RA patients with joint effusion were higher than that of without(t=2. 587,P=0. 012). The levels of IL-22 in SF were higher than that in serum(t=2. 668,P=0. 011),and had no correlation with the proportion of Th22 cells in SF. Conclusion: The expression of IL-22 in serum and joint effusion of RA patients increase. The level of IL-22 may be useful marker for assessment of disease activity and finding of bone erosions. Therapeutic targeting of IL-22 may be valuable for the intervention of RA.

ABSTRACT

Objective The Study the difference of miRNA expression of AIDS patients with toxic heat accumulation syn -drome with healthy control group .Methods This research used Agilent miRNA chip to test the miRNA of blood preparation ,and used SAS system to screen the differences between groups ,then analyzed the significance function of target gene .Results Compare the heat-toxic accumulation group and the healthy control group ,100 cases of obvious expression difference and of which the differ-ence was 2 times and greater were screened out (in which 64 cases showed up-regulation and 36 showed down-regulation) .Differen-tially expressed miRNAs function involves the role of IL-21 receptor in T cell activation ,C reactive protein ,and the positive regula-tion of the immune response .Conclusion AIDS toxic heat accumulation syndrome patients and healthy control groups exist differ -ences in miRNA expression profiles ,the biological basis of syndrome maybe related to T cell activation and IL-21 receptor .

ABSTRACT

Objective To explore the clinical effects of S-1 single agent chemotherapy for the patients undergoing radical resection of cholangiocarcinoma.Methods The clinical data of 51 patients receiving radical resection of cholangiocarcinoma who were admitted to the Second Affiliated Hospital of Zhejiang University from November 2011 to December 2013 were retrospectively analyzed.After radical resection of cholangiocarcinoma,25 patients receiving non-special treatment and 26 patients receiving S-1 single agent chemotherapy were divided into the operation group and chemotherapy group,respectively.S-1 was taken orally twice per day.Forty mg/once of S-1 was applied to patients with the body surface area < 1.25 m2,50 mg/once of S-1 was applied to patients with the body surface area ≥ 1.25 m2 and < 1.50 m2,and 60 mg/once of S-1 was applied to patients with the body surface area ≥ 1.50 m2.The 14 days usage and 7 days withdrawal of S-1 were used as one course of treatment.The standard usage of S-1 was 6-8 courses of treatment.All the patients were followed up by outpatient examination and telephone interview till December 1,2014.Count data were analyzed using the chi-square test.Measurement data with normal distribution were presented as (x) ± s and analyzed using the t test.Survival curve was drawn by the Kaplan-Meier method,and survival analysis was done using the Log-rank test.Results Twenty-six patients in the chemotherapy group finished the courses of chemotherapy without chemotherapy-related death,and 14 patients had chemotherapy adverse reactions with remission after discontinuation of S-1.All the 51 patients were followed up for 5-37 months with a median time of 19 months.The median overall survival time,1-,3-year overall survival rates,tumor-free median survival time and 1-,3-year tumor-free survival rates were 22 months (range,18-27 months),72.3%,42.9%,21 months (range,16-26 months),60.0%,55.0% in the operation group and 32 months (range,29-35 months),84.6%,44.4%,26 months (range,21-31 months),76.9%,61.9% in the chemotherapy group,respectively.There was a significant difference in the overall survival between the 2 groups (x2=6.032,P < 0.05).There was no significant difference in the tumor-free survival between the 2 groups (x2=0.498,P > 0.05).Conclusion S-1 single agent chemotherapy after radical resection of cholangiocarcinoma could improve the survival of patients,while no obvious advantages of inhibiting tumor recurrence is observed.
