RESUMO

Objective: To evaluate the effectiveness and benefit of the upper gastrointestinal cancer screening in Yangzhong city, Jiangsu province, from 2009 to 2015. Methods: From 2009 to 2015, 31 natural villages with high-incidence of upper gastrointestinal cancer were selected from Baqiao town, Youfang town and Xinglong sub-district in Yangzhong city. 13 776 residents aged 40 to 69 years old were recruited and screened for upper gastrointestinal cancer by using endoscopic examination and pathological diagnosis. Two economic evaluation methods, cost-effectiveness analysis and cost-benefit analysis, were performed to evaluate the current screening schemes. Results: The mean age of all respondents were (53.60±8.14) years old and the males accounted for 43.64% (6 012). A total of 502 cases of upper gastrointestinal tract lesions were detected, including 100 cases of cancer (62 cases of esophagus, gastric/cardiac early stage cancer, 38 cases of advanced stage cancer), 38 cases of severe esophageal hyperplasia/carcinoma in situ, and 15 cases of high-grade intraepithelial neoplasia in stomach/cardia, the detection rate was 0.73%, 0.28% and 0.11%, respectively; the early diagnosis rate was 75.16% (115/153). The cost of a precancerous lesion, a case diagnosed at the early stage and a positive case identified through the upper gastrointestinal cancer screening in Yangzhong City was 10 037.17, 30 460.64 and 22 895.25 RMB, respectively. The early detection cost index from 2009 to 2015 was 0.52, 0.56, 0.48, 0.48, 0.21, 0.30, and 0.26, respectively. The effectiveness-cost ratio from 2009 to 2015 was 3.41, 2.77, 2.66, 2.58, 4.99, 3.12, and 3.48, respectively. Conclusions: The project of early diagnosis and treatment of upper gastrointestinal tract cancer in Yangzhong city has achieved good results and benefits.

RESUMO

OBJECTIVE: Using angiography, this study examined left atrial appendage (LAA) morphology in Chinese patients with atrial fibrillation (AF) or congenital atrial septal defects (ASD), to provide data that might aid the design of new LAA-occluding devices to prevent cardioembolism and stroke in patients with AF. METHODS: Patients with AF or ASD were enrolled. The LAA was visualized angiographically; its dimensions were measured and the emptying fraction was calculated. RESULTS: A total of 45 patients with AF and 30 patients with ASD were included in the study. LAA morphology was classified into eight categories. The majority of patients with AF had tube-shaped LAAs with a single lobe; the most common LAA morphologies in patients with ASD were irregular or sphere-like, with multiple lobes. Patients with AF had significantly larger LAAs with significantly lower emptying fractions compared with LAAs of patients with ASD. CONCLUSIONS: The LAA demonstrated considerable morpho logical variability in terms of its size, shape and number of lobes. The design of new occluding devices must take into account the size and shape of the LAA in patients with AF.

RESUMO

This study investigated the effect of ginsenoside Rg1 on the functions of ex vivo cultivated endothelial progenitor cells (EPCs) and whether ginsenoside Rg1 prevented EPC senescence. EPCs isolated from peripheral blood from healthy volunteers were incubated with different concentrations of ginsenoside Rg1 and the effects were observed at different time points. Cell proliferation and in vitro vasculogenesis were assayed and flow cytometry was used to determine the effects of ginsenoside Rg1 on the cell cycle. Senescence and telomerase activity in EPCs were also assayed. It was found that ginsenoside Rg1 promoted EPC proliferation and vasculogenesis in dose-and time-dependent manners. Cell-cycle analysis showed that ginsenoside Rg1 increased the proliferative phase and decreased the resting phase of EPCs. ß-Galactosidase and telomerase activities increased. These results support the view that ginsenoside Rg1 induces EPC proliferation and angiogenesis, and inhibits EPC senescence.
