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.
2.Research progresses on relationship between Wnt inhibitory factor-1 and tumor
China Oncology 1998;0(04):-
WIF-1 is an important antagonist in the Wnt/?-catenin pathway.As a tumor suppressor, WIF-1 is down-regulated in majority cancers but when it is correlated with WIF-1 promoter hypermethylation and treated with demethylation drug, its expression can be restored.Functional loss of WIF-1 due to promoter hypermethylation plays an important role in a tumor's pathogenesis, possibly mainly through aberrant canonical Wnt/?-catenin signal activation.The correlation of the expression of WIF-1 with clinicopathological features in different cancers is not identical.Detecting WIF-1 and promoter hypermethylation may offer help for early diagnosis, therapy and predicting prognoses.

Objective To investigate neurogenesis in the dentate gyrus of adult rat following conditioned fear stimulus.Methods 24 adult male rats were randomly divided into conditioned fear stimulus group and control group,and all rats were intraperitoneally injected bromodeoxyuridine(BrdU)3 days before conditioned fear stimuli.Animals in conditioned fear stimulus group were given monotone matching foot shock and made conditioned fear stimulus model,animals in control group only give monotone.Freezing time was detected before stimuli and 7th,14th days after stimuli,then rats were sacrificed 7th or 14th day after fear conditioned stimulus,and immunohistochemistry for Brdu was detected.Results Behavioral assessment showed that the percents of freezing time in conditioned fear stimulus group 7th,14th days after conditioned fear stimulus were significantly high(88.68%,91.33%)than those in control group(11.18%,14.23%,P<0.01)and before stimulus(24.11%,16.11%,P<0.01).Compared to control group(1567±28,580±5),Brdu positive cells in dentate gyrus of rat in conditioned fear stimulus group(1364±21,296±22)were decreased,and it reached to a statistical significance on 14th day (P<0.05).Conclusion The decreased neurogenesis in the dentate gyrus of adult rat following conditioned fear stimuli may have relation to fear and other emotion memory.

Objective To investigate the prevalence,awareness,control status and associated risk factors of hypertension in a rural population in Xianghe county in North China.Methods A total of 830 adults (aged≥35) from Xianghe county were examined during July to August,2011.Blood pressure was obtained using a standardized sphygmomanometer after a 5-minute sitting rest.Information on gender,age,education level,marital status,smoking,drinking,income,family history of hypertension and use of antihypertensive medications was obtained.Results A total of 42.4% of all subjects had hypertension.Among those with hypertension,the awareness rate was 54.8% and 50.0% of the patients were taking antihypertension medication with the control rate of 11.9% [BP < 140/90 mm Hg (1 mm Hg =0.133 kPa)].Lower age and education level,lower body mass index,negative family history of hypertension were associated with poor awareness of hypertension and worse compliance with the treatment.Older age,positive family history and alcohol consumption were associated with poor blood pressure control.Conclusions Hypertension is highly prevalent in Xianghe rural area.The awareness,treatment and control rate are all low.There is an urgent need for comprehensive strategies to improve prevention,screening,and treatment of hypertension in rural China.

BACKGROUND:The siphon of internal carotid artery is a complex of bending and surrounding structure, which has become a research hot in the field of medical imaging and regional anatomy. There is little research on the hemodynamics of internal carotid artery. Finite element analysis provides the basis for the related dynamics research. OBJECTIVE:To explicit the hemodynamic characteristics of the normal and stenosis internal carotid artery, and to explore the relevant influential factors. METHODS:Finite element model of the siphon of internal carotid artery was built based on 64-slice spiral CT data, and then, three-dimensional models were constructed using Mimics 10.01 software. There were simulations of the normal and post-stenosis blood flows with ANSYS 13.0 CFX software, to observe the changes of hemodynamics, and to analyze their characteristics and differences. RESULTS AND CONCLUSION:The normal blood flow at the siphon of internal carotid artery was in a laminar state, but rotation and turbulent flow formed at the two angle regions. The velocity of external bending zone was slower than that of the internal. The slower was the velocity, the more obvious was the turbulence. The wal shear force decreased at the angle regions, and the wal shear force of external bending zone was smal er than that of the internal. At the region of arterial stenosis, the blood flow was sped, and at the downstream, turbulent flow and low zone of wal shear force were formed. With the increase of stenosis severity, the turbulent flow and low wal shear force area were expanded. Central stenosis showed more obvious effects than the eccentric one. The degree of stenosis and bending at the siphon of internal carotid artery can directly influence the formation of turbulent flow and low wal shear force area, which are more obvious at the external bending zone and central stenosis.

Objective To observe the effect of Zusan Li acupoint injection with Chuankezhi injection ( CI) combined with chemotherapy on the quality of life in the stage III or IV senile patients with non-small cell lung cancer (NSCLC) . Methods We adopted research methods for the prospective, randomized, and controlled trial. A total of 62 qualified patients completed the treatment program, and were randomly divided into two groups. Thirty-two patients in the test group received CI combined with chemotherapy and syndrome differentiation treatment, and 30 patients in the control group were given chemotherapy and syndrome differentiation treatment. We used the WHO Quality of Life Older Module Scale ( WHOQOL-OLD) , Functional Assessment of Cancer Therapy-Lung ( FACT-L V4.0) and the Brief Fatigue Inventory ( BFI) to evaluate and analyze the quality of life before and after treatment. Results (1) In the WHOQOL-OLD evaluation, the total scores and the scores of dimensions of sensory abilities, autonomy, social participation, and past, present and future behavior were much improved in the test group after treatment ( P﹤0.01 compared with those before treatment) , while the control group only had statistically significant difference ( P﹤0.01) in the improvement of social participation and the total scores. The test group had higher scores difference in autonomy than the control group (P<0.01) . (2) In the FACT-L V4.0 evaluation, the total scores and the scores of domains of physiological condition, emotional status, functional status, and additional attention were much improved in the test group ( P﹤0.01 compared with those before treatment) , and the control group had an improvement in the total scores and scores of emotional status and additional attention after treatment ( P<0.01) . The test group had higher scores difference in physiological condition, functional status, and additional attention than the control group (P<0.01) . (3) In BFI evaluation, the degree of fatigue and fatigue influence were improved in both group after treatment ( P﹤0.01 compared with those before treatment) , and the improvement in the test group was superior to that in the control group ( P<0.05) . Conclusion Zusan Li acupoint injection with CI can improve the quality of life of senile NSCLC patients treated with chemotherapy in dimensions of sensory abilities, autonomy, social participation, and past, present and future behavior, and in domains of physiological conditions, functional status, additional concern, and it can also improve the degree of fatigue and fatigue influence.
