Chinese Health Economics 2013;(7):38-39
Objective: According to ERG ( Existence Relatedness Growth) needs theory, analyze factors influencing the resignation probability in Township Health Centers (THC). Methods: Structural equation model was used based on ERG needs theory. The sample consists of 403 stuffs in the THC. Results: The result of model fitting goes well. The satisfaction levels of the needs to survive and the needs of relationship become the major influencing factors of resignation probability in the THC. Conclusion: To reduce the resignation probability in THC, it needs to guarantee their income and benefits, improve working condition and living convenience facilities.
3.Advance in the study of complication of anti-vascular endothelial growth factor following intravitreal injection
Chinese Ophthalmic Research 2009;27(11):1039-1043
The efficacy of intravitreal injection of anti vascular endothelial growth factor(VEGF) drug has been recognized for the treatment of choroidal neovascularization(CNV) secondary to age-related macular degeneration(AMD), central exudative chorioretinopathy and pathological myopia, proliferative diabetic retinopathy (PDR), retinal vein occlusion, retinopathy of prematurity and neovascular glaucoma. The tendency of clinic application of anti-VEGF is increasing. Though the therapeutic effect of anti-VEGF has been confirmed, a variety of complications associated with its usage were reported. This review summared the advancement of the complication in the clinical application of anti-VEGF therapy such as its effect on normal structure and physiological function of eye, intraocular pressure elevation, rips of retinal pigment epithelium(RRPE), retinal detachment(RD), endophthalmitis and systemic side-effects.
4.Analysis on equity of health resource allocation before and after new health system reform in China
Chinese Journal of Health Policy 2017;10(9):46-50
This paper aims at describing and comparing the changes of health resources allocation before and after new health system reform during 2006—2015 . Methods:Province-level data were used to analyze the inequities of licensed ( assistant) doctors and beds. 31 provinces were divided into 5 groups by GDP per capita and 3 groups by geographical regions. Absolute difference, relative ratio and concentration index were respectively used to compare and measure the absolute difference, relative difference and inequities in different groups before and after the new health system reform. Results:The findings of this study show the allocation of China's health resource before and after new health system reform to be as below:(1) the quantity of health resource is increasing, and the growth rate after the reform is higher than before. (2) the disparities of health resource in different economic development level areas are declining, and the decrease is faster after the reform. (3) the disparity of beds in different regions is decreasing, but the disparity of licensed (assistant) doctors in different regions is enlarging. (4) The inequities of health resource al-location in China are reduced, and the improvement is greater after the reform than before. However, the health re-source allocation is still highly inequitable to geographical areas. Discussion:(1) the policies of health resource allo-cation implementation after the reform needs improvement. ( 2 ) The amount of health resource still needs to be in-creased in certain areas, especially need to strengthen the training of high-qualified health personnel. (3) When al-locating health resources, government should focus on the impact of both population and geographical size factors.

Objective To investgate the proper perioperative management of Debakey Ⅰ aortic dissection by new type of three branches aortic arch covered stent graft implantation. Methods A total of 56cases with Debakey Ⅰ aortic dissection were enrolled into the study and operated by new type of three branches aortic arch covered stent graft implantation from July 2009 to August 2010. Results The cardiopulmonary bypass time during the operation was 90. 0 -248.0 min( median time 180. 6 ains) ,aortic cross clamp time was 69. 0 - 180. 0 min(median time 108. 2 mins) ,circulation arrest time was 17.0 -37.0 min ( median time 22. 6mins) ,the time using reathing apparatus was 16.0 -260.0 hours (median time 42. 8 hours),ICU residence time was 3.0 -23. 0 days( median time 6. 6 days). Fifty-four patients got well and were discharged. One patient died of multi-organ failure postoperatively and another died of large area of acute myocardial infarction. After the operation, six cases had acute renal failure, five cases had tracheotomy, three cases had reoperation for hemorrhage,one case had retardant pericardial tamponade, one case suffered from spinal cord injury, one had cerebral hemorrhage, and five cases had refractory arrhythmias. Conclusion The new type of three branches aortic arch covered stent graft simplified the procedures of aortic arch operation and lowered the operative risk in treatment of Debakey Ⅰ aortic dissection. Properly control of blood pressure and pain before surgery, shorten circulatory arrest time, maintain good organ perfusion seem to be the key points to improve the prognosis in patients with aortic dissection.

Objective To investigate the risk factors of hemorrhagic transformation (HT) after cerebral infarction. Methods The clinical and neuroimaging data of 100 patients (gender,age-matched)with cerebral infarction and hemorrhagic transformation from January 2005 to January 2010 were analyzed retrospectively. The following factors were listed for single factor analysis: the history of hypertension, diabetes mellitus,admission blood pressure,blood sugar,infarction size,alcohol,smoking,atrial fibrillation,hypercholesterolemia, combined anticoagulant and antiplatelet aggregation therapy. All the above factors were analyzed by chi-square test or t test, and Logistic regression analysis was used to screen out the related risk factors of HT from the potentially related factors. Results Atrial fibrillation (OR =5.483,95%CI:fibrillation,extensive cerebral infarction,blood sugar,high blood pressure at the beginning of the disease,combined anticoagulant and antiplatelet aggregation therapy are the major risk factors of HT. At the same time, the occurrence of HT is the result of the joint effect of multiple factors and multiple mechanisms.

Objective To investigate the effects of airborne fine particulate matter(PM2.5) on anti-oxidative enzymes activities and lipid peroxidation levels in livers, spleens, and kidneys of rats. Methods 32 male Wistar rats were randomly divided into PM2.5 exposure groups of different concentration (1.5, 7.5, 37.5 mg/kg), exposed by tracheoperfusion and control group treated with physiological saline. Rats were killed 24 h after treatment, and the levels of thiobarbituric acid reactive substance (TBARS), glutathione(GSH) and activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase (CAT) were determined. Results PM2.5 exposure caused significantly decrease of SOD, CAT, GSH-Px, SOD/TBARS in livers and kidneys in a dose-dependent manner compared with control group (P

AIM:Methylglyoxal (MG) is considered as a very active free radical,which is an important contributor to diabetic complications such as cataracts. The purpose of this study was to investigate the serum MG levels and protective effects of soybean isoflavones on streptozotocin induced diabetes. METHODS:Diabetes was induced in male Sprague -Dawley rats by intraperitoneal injection of 100 mg/kg streptozotocin (STZ). Diabetic rats were then randomly di-vided into 3 groups and received a special diet supplemented with casein (diabetes),low -isoflavone soy protein (diabetes + LIS),or high-isoflavone soy protein (diabetes + HIS) for 8 weeks,respectively. RESULTS:Compared to the diabetes or diabetes + LIS groups,diabetes + HIS diet significantly increased serum insulin levels,and reduced serum glucose,HbA1c and methylglyoxal levels (P
