Cornea is an important part of the refractive media.Healthy cornea is clear and avascular.Corneal avascularity is necessary for the preservation of optimal vision and is maintained by a balance between angiogenic and antiangiogenic factors.In a variety of pathologic conditions,the balance between angiogenic and antiangiogenic factors may be tipped towards angiogenic molecules,leading to corneal neovascularization (CNV).Recent research showed that vascular endothelial growth factor (VEGF) is an important factor responsible for CNV.Over the past several years,the safety and efficacy of several new agents targeting VEGF or VEGF receptor (VEGFR) have been verifies in many ocular neovascularization diseases such as age-related macular degeneration, diabetic retinopathy, neovascular glaucoma,retinopathy of prematurity and CNV.These agents not only have revolutionized the therapy of ocular neovascularized disease but also have great potential for other blinding conditions such as CNV.These agents have great potential for the treatment of CNV.This article reviewed the most promising anti-VEGF/VEGFR therapies.

Under certain conditions,stress can bring physiological,behavioral or psychological response,thus affect human health and cause diseases.Available intervention methods must be adopted to eliminate or relieve internal environment disorder from severe stress.Studies of stress intervention are of great importance to maintain and promote physical and psychological health.According to the different characteristics,stress intervention methods can be divided into psychological and behavioral.This review presented the advance of stress intervention methods.

Mammalian target of rapamycin ( mTOR) is a kind of Ser/Thr kinase existing in mammalian cells can regulate cell proliferation, migration and angiogenesis.mTOR including two different complex forms as mTORC1 and mTORC2 .Rapamycin and rapalogs were soon found to have powerful immunosuppressant prop-erties and thus be valuable for preventing the progress of the artery atheromatous by inhibiting the function of mTORC1.But long-term rapalogs administration may increase the side actions such as mTORC1 resistance, mTORC2 inhibition, dyslipidemia.The clinical application of drug combination and dosage optimization may reduce adverse events.

The Kashin-Beck disease is a kind of unknown cause disabling arthropathy.In recent years,many experts and scholars have done in-depth studies in Kashin-Beck disease.There is a series of research achievements having been made.In this paper we reviewed the latest progress in the condition,etiology and pathogenesis of Kashin-Beck disease.

On the anatomy, posterior vitreous cortexneighbors with retina, the relationship of vitreous and retinal is both independent and closely linked. Under pathological condition, changes in the vitreous provides a good environment for occurrence and development of a number of vitreoretinal diseases, which indicates that vitreous plays a crucial role in many vitreoretinal diseases occurrence and growth. Elimination of vitreous change in disease, is an issue of great concern of the ophthalmic industry in recent years. Based on the description of vitreous and vitreoretinal interface structure, changes in the vitreous and retinal adhesion mechanisms and interfaces retinal disease risk factors and the impact on the retinal disease were discussed, And the posterior vitreous detachment impact on the vitreoretinal interface disease, the testing methods and its importance were described in this article.

Objective To study the expression of CXCL12 and E-cadherin in condyloma acuminatum (CA) lesions caused by low-risk type (HPV6 and HPV11) humanpapilloma viruses. Methods The expressions of CXCL12 and E-cadherin mRNA in the lesions of CA caused by HPV6 and HPV11 and in the foreskins from normal males as controls were detected by real-time fluorescent quantitative PCR. Results The expressions of CXCL12 in the lesions of CA were down-regulated (fold change = 20.23,P = 0.001), and the expressions of E-cadherin were up-regulated (fold change = 3.129,P > 0.05). Conclusions The expression of CXCL12 is lower and the expression of E-cadherin is higher in the lesions of CA caused by low-risk HPV. It suggests that HPV may suppress local immune response and change the adhesion between langerhans cells and keratinocytes , which may contribute greatly to the persistent infection of HPV and relapse of CA.

Objective This paper sums up professor Zhang Peiying's clinical experience in diagnosing and treating unstable angina(UA) of coronary heart disease. [Methods]Generalizing the pathogenesis, rules of treatment and principle of diagnosis about UA, through the reference of classical theory of Traditional Chinese medicine and clinical observation. Then analyse professor Zhang Peiying's characteristics about diagnosing and treating UA by two examples of medical record.[Results]Professor Zhang considers deficiency of Qi and stagnation of phlegm is the premise and foundation of UA, holds that stagnation of phlegm, stagnation of blood and spasm of heart vessel are the key causes of the disease and removing blood stasis, relieving spasm of vessel, strengthening the spleen and reducing phlegm is the basic treatment principle. He divides UA into 4 categories: stagnation of heart blood syndrome, stagnation of phlegm and blood syndrome, deficiency of Qi and stagnation of blood syndrome,weakness of Yang with stagnation of phlegm and blood. [Conclusions]Professor Zhang Peiying's scholar thought and clinical experience in diagnosing and treating UA of coronary heart disease is effective. His thought and clinical experience are worth extending and applying.

Objective:To explore the effect of zuoguiyin and its partial prescriptions on cellular immune function in senile mice.Methods:Healthy male ICR senile mice were divided into 4 groups at random: old contrast group, ZGY group, prepared rhizome of rehmannia(PROR) group and none prepared rhizome of rehmannia(NPROR) group. The senile mice had been drunk zuoguiyin and its partial prescriptions for 75 days, then observing the differences through thymic index, spleen index, activity of T lymphocyte and the level of IL-2 after using different drugs.Results:Acted by ZGY, ZGY had enhanced cellular immune function of senile mice, appearing that thymic index, spleen index, activity of T lymphocyte and the level of IL-2 were distinctly higher than those of the old contrast group. Compared to ZGY,prepared rhizome of rehmannia also enhanced the activity of T lymphocyte. However, it had no effect on thymic index, spleen index and the level of IL-2.So its effect on anti-senility was not better than ZGY. None prepared rhizome of rehmannia group had no distinct effect on those indexes.Conclusion:Zuoguiyin had an action of antisenility by improving cellular immune function.

ObjectiveTo study the protective effects of fluvastatin on the renal lesions in diabetic rat. MethodsThe model of diabetic rats was induced by streptozotocin. SD rats were random divided into four groups: Control group, diabetic rats group, low-dose fluvastatin group 2mg/(kg·d) and high-dose fluvastatin group 4 mg/(kg·d). After treatment for 4 weeks, serum cholesterol, serum creatinine and urinary protein were measured respectively. The expression of TGF β1 in the renal cortex was determined by RT-PCR. ResultsFluvastatin inhibited the expression of TGF-β1 Mrna in a dose-dependent manner, and had no influence on urinary protein, serum cholesterol and serum creatinine. ConclusionsFluvastatin inhibits the overexpression of TGF-β1Mrna, which may be related to independent cholesterol decreasing effect.

Objective To evaluate the effect of age on pharmacodynamics of eisatracurium target-controlled infusion(TCI). Methods Forty patients under N_2O-O_2-propofol-fentanyl anesthesia were divided into groups of Ⅰ and Ⅱ with 20 cases each. Under TOF stimulation monitoring, eisatracurium 0. 15 mg/kg was injected and tracheal intubation was performed when TOFr being zero. and the intubation conditions were evaluated. When T1 restored to 50% cisatracurium TCI started to keep TOFr less than 10%. The recovery times of neuromuscular blockade were recorded after stopping infusion. The amount of cisatracurium consumption was calculated. Results Intubation conditions the onset time and recovery index were not significantly different between two groups. The nonresponse period, duration of action, and recovery time were longer in group Ⅰ than those in group B. Cisatracurium consumption was more in group Ⅰ than that in group Ⅱ (P<0.05). Conclusion By TCI,cisatracurium dosage needed for keeping TOFr less than 10% is less,but the recovery process is still longer in the elderly than those in the younger.
