Objective To discuss the present situation and existing problems of the funded projects, especially in the gap between western region and eastern central region by analyzing the funding situation of the projects funded by the National Natural Science Foundation of China (NSFC) and the completed projects in the TCM field from 1989 to 2015. Methods The website was searched thoroughly, and data of Division Ⅹ of Health Science Department of National Natural Science Foundation of China from 1989 to 2015 (ie TCM, Chinese materia medica and integrated traditional Chinese and Western medicine) funded by the National Science Foundation for Young Scientists in China were obtained, and the projects of the National Science Foundation for Young Scientists funded by Division Ⅹ of Health Science Department of National Natural Science Foundation of China from 1989 to 2015 were included, and incomplete or inavailable items were eliminated. Relevant information according to the extracted forms was extracted. The situation of different regions and the situations of the projects have been concluded and the titles of different titles have been analyzed. Results By 2015, the number of funded projects and the amount of financing in the TCM field were increasing year by year. In the western regions, the number of funded projects and the amount of financing accounted for only 11.29% of the total number and 11.28% of the total financing. Compared with the less supporting western regions, much more were mainly in eastern and central regions. The number of SCI papers published and single cited times of the finished projects were 988 and 20.85. Compared with the developed areas in eastern and central regions, there was no statistical significance in the average number of SCI papers (P=0.493), average SCI papers cited article number (P=0.449), SCI papers in average cited frequency (P=0.589), the average CSCD papers number (P=0.579), average CSCD papers cited article number (P=0.883) and average single CSCD papers cited frequency (P=0.753) in western regions (P>0.05). Conclusion Under the stable supports of the Young Scientists Fund, scientific researches in the TCM field have achieved remarkable achievements. In addition, the ability of scientific research and innovation of the young scientific workers have been improved. The funded projects in western regions are far less than those in eastern and central regions, with great differences. However, there is no statistical significance in the research results of the items in western regions and eastern and central regions.

OBJECTIVE:To study the safety and efficacy of Neuroform self-expanding stent for symptomatic intracranial artery stenosis.METHODS:A total of 37 patients with symptomatic intracranial artery stenosis received treatment at the Department of Neurosurgery,Affiliated Hospital of Behua University and Xuanwu Hospital were selected,who were ineffective to anticoagulation and antiplatelet treatment,including 24 males and 13 females,aged from 49 to 72 years,mean aged 64 years.All patients were received Neuroform self-expanding stent following angiography.RESULTS:All patients underwent PTAS with mean preoperative stenosis were reduced from 64% to 24% after percutaneous transluminal angioplasty (PTAS).The technically successful rate was 100%.All the patients were received a 6-22 month follow-up (average 13 months).The average artery stents was retrieved by 50%-90% after stent deployment.There was no arterial dissection,acute occlusion of the target artery or symptomatic distal emboli.Within the follow-up period,1 patient endured asymptomatical artery full occlusion.Two stents were implanted simultaneously in 3 patients,1 of them suffered bilateral vertebral artery stenosis,and 2 had right vertebral arterial and basilar artery stenosis.One patient suffered acute in-stent thrombosis and recovered after thrombolytic therapy.No pathogenetic condition was aggravated in the follow-up.CONCLUSION:The application of Neuroform self-expanding stent can alleviate the ischemic symptoms of patients with vertebrobasilar stenosis and elevate the operative safety and effectiveness.However,further study is needed to evaluate the long-term therapeutic effect.

Objective: To analyze the premature death probability and cause-eliminated life expectancy of cardiovascular disease, cancer, chronic respiratory disease and diabetes in Chongqing residents in 2016 so as to provide recommendation for non-communicable diseases (NCDs) prevention and control in Chongqing. Methods: Death cases of Chongqing Municipality between January 1^st and December 31^st, 2016 were reported through death case registry system of national center for disease prevention and control. Death cases were sorted by international classification of disease (ICD-10). Mortality rate, standardized mortality rate, constituent ratio, premature death probability, life expectancy, and cause-eliminated life expectancy of four major NCDs were analyzed. Results: A total of 218 004 death cases were reported in Chongqing, 2016, and the mortality rate was 731.73/100 000. Of them, a total of 179 637 death cases of the four major NCDs including cardiovascular disease, cancer, chronic respiratory disease and diabetes were reported, accounting for 82.40% of all death cases. The mortality rate and standardized mortality rate of four major NCDs was 602.95/100 000 and 455.82/100 000, respectively. The premature death probability of four major NCDs was 15.96%, and males (25.39%) had a higher premature death probability than females (10.78%). The premature death probability of cardiovascular disease, cancer, chronic respiratory disease, and diabetes were 6.01%, 8.32%, 2.05%, and 0.43%, respectively. Life expectancy would increase by 6.02, 3.19, 1.89, and 0.19 years, after eliminating cardiovascular disease, cancer, chronic respiratory disease and diabetes respectively. Conclusion The premature death probability of major NCDs was high in Chongqing, and males had a higher premature death probability than females did. Intervention and health management of the population should be conducted according to different gender-based risk factors to reduce the premature death probability.
