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.

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 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

Objective To investigate and analyze the clinical value of minimal invasive surgery with laparoscope for radical hysterectomy and pelvic lymphadenectomy for the treatment of cervical and endometrial carcinomas in early stage. Methods A retrospective analysis was carried out based on the clinical data of 64 patients with FIGO stage Ⅰ-Ⅱ malignant uterine tumor, among them 34 were operated with the aid of laparoscope and 30 were operated with laparotomy for radical hysterectomy and/or pelvic lymphadenectomy. Comparison was done between the two groups on operative time, blood loss, complications and postoperative recovery. Results There was no significant difference in the incidence of complications and operation time between laparoscopic radical hysterectomy and pelvic lymphadenectomy for the treatment of the patients diagnosed with early stage of cervical and endometrial carcinomas compared with those with traditional radical hysterectomy and pelvic lymphadenectomy through laparatomy. Laparoscopic radical hysterectomy and pelvic lymphadenectomy for the treatment of early stage of cervical and endometrial carcinomas resulted in less blood loss (247.13?127.62ml vs 904.51?428.37ml, 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

Of the 250 cases of blunt abdominal trauma,15 cases of pancreatic lesions were complicatedwhich include 3 cases lacerated on the head of pan-creas, 5 on the body, 6 on the tail and one con-tused. The pancreatic bed drainage was performedfor one case, repair for 8 cases and pancreatic tailresection for 6 cases, In author's experiences, theroutinely inspecting the pancreas was carried outintra operatively, with blunt epigastric trauma, es-pecially the light red hemotoliquid was found bypericentesis. Operative method was classified frompancreatic bed drainage, repair and resection in ac-cordance with severity of the trauma, For prevent-ing the pancreatic juice fistula, the main pancreaticduct must try its best to be ligated. If the traumais on the head, a common bile duct and duodenumdecompression must be done.
