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 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

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.

Objective To compare the effects of epidural administration of different combinations of lidocaine, corticosteroids (dexamethasone, prednisolone) and vitamins(B 1,B 6,B 12 ) on epidural space adhesion and nerve root inflammation in rabbits Methods Forty eight adult Japannese white rabbits of either sex weighing (2 38?0 31)kg were anesthetized with intramuscular ketamine 15 mg?kg -1 and midazolam 0 2 0 3 mg?kg -1 A catheter was inserted into epidural space at L 2 when the ligamentum flavum was exposed by surgery and advanced caudally for 2 3cm Correct placement of the catheter in epidural space was confirmed by injecting 0 5% lidocaine 0 2 ml through the cathter when the animal was awake 24h after epidural cathter placement 0 2ml?kg -1 of normal saline containing talcum power 1mg?ml -1 was injected into epidural space 3 days later the animal were randomly divided into 8 groups: group Ⅰ received no treatment, group Ⅱ epidural normal saline 0 2ml?kg -1 , group Ⅲ epidural 0 5% lidocaine 0 2ml?kg -1 , group Ⅳ epidural compound lidocaine solution 1 (lidocaine 100mg +dexamethasone 10 mg in 20 ml normal saline) 0 2ml?kg -1 , group V epidural compound lidocaine solution 2 (lidocaine 100mg+prednisolone 50 mg in 20 ml normal saline)0 2 ml?kg -1 , group Ⅳ epidural compound lidocaine solution 3 (lidocaine 100mg+dexamethasone 10 mg+vitamin B 1 200mg in 20 ml normal saline) 0 2 ml/kg, group Ⅵ epidural compound lidocaine solution 4 ( lidocaine 100mg+dexamethasone 10 mg+vitamin B 6 200mg in 20 ml normal saline) 0 2 ml/kg, and group Ⅷ epidural compound lidocaine solution 5 (lidocaine 100mg+dexamethasone 10 mg+vitamin B 12 200mg in 20 ml normal saline) 0 2 ml/kg One week later animals were killed by intravenous injection of air Spinal column below L 1 was removed Epidural space and nerve root adhesion was checked first with naked eye then examined under microscope Epidural space adhesion was divided into 4 grades according to Rydell Results 1 Macroscopic examination of epidural space for adhesion: there was no significant different between group Ⅰ and group Ⅱ,Ⅲ, also between group Ⅱ,Ⅲ and group Ⅳ,Ⅴ,Ⅵ,Ⅶ,Ⅷ; there was significant different between group Ⅰ and groupⅣ,Ⅴ,Ⅵ,Ⅵ,Ⅷ (P

[Objective] To investigate the effects of Eucommia on renal interstitial fibrosis and its mechanism.[Methods]Using renal interstitial fibrosis in rats with Unilateral Ureteral Obstruction(UUO).Adult female SD rats(n=32) were randomly divided into 4 groups: Sham operation group (Sham); UUO group,Irbesartan group; Eucommia group.Undergo light microscopy by Masson and HE staining to observe the renal interstitial fibrosis index.To detect the expression of MMP-2 by immunohistochemistry 2w after surgery.[Results] 1.The levels of BUN and Scr in UUO group were significantly higher than in Sham group.Compared with UUO group,the levels of BUN and Scr in irbesartan and eucommia groups were significantly lower.There was no significant difference between irbesartan group and eucommia group.2.The renal tissue was stained with HE.There was no change in Sham group.But in UUO group,there was tubular epithelial cells denaturalization,renal tubular expand or atrophy,interstitial macrophage and monocyt infiltration,interstitial expand,and there was no glomeruli change.While the change in irbesartan and eucommia group was slighter than that in UUO group.There was no significant difference between irbesartan group and eucommia group.3.The renal tissue Masson staining showed that there was interstitial expands fibrous tissues proliferation and there was no glomeruli change in UUO group.Compared with UUO group,the level of pathological change in irbesartan and eucommia groups was significantly lower.There was no significant difference between irbesartan group and eucommia group.4.The expression and distribution of MMP-2 were strong in Sham group,while in other groups lower in renal interstitial.Compared with UUO group,the level in irbesartan and eucommia groups was significantly higher.There was no significant difference between irbesartan and eucommia groups.[Conclusion] Eucommia inhibits the renal interstitial fibrosis lesion up-regulating the MMP-2 expression and blocking renal fibrosis.
