·AIM: To study the expressive variation of Nogo-A on rat retina in the process of chronic ocular hypertension. · METHODS: Thirty-six healthy adult male Wistars were randomly divided into control group (6 rats) and chronic hypertension group (30 rats). Chronic hypertension was created by cauterizing the superficial scleral veins. Immunohistochemistry technique was used to evaluate the expressive varieties of Nogo-A at different time points during the course of chronic ocular hypertension. · RESULTS: The success of the model was indicated by over 40% of increase in the IOP as compared with normal rats. Compared with control group, as time passed chronic hypertension group gradually had detectable morphology changes in the retina. At the 21st day of chronic ocular hypertension, retinas became thinner and the quantity of retinal ganglion cell (RGC) decreased (P<0.05). Assoicated with the morphological changes, the expression of Nogo-A was strongly increased (P<0.05).CONCLUSION: Myelin associated protein Nogo-A plays a part in the process of chronic ocular hypertension.

AIM:To compare one-site vs two-site phacotrabe-culectomy in chronic angle-closure glaucoma (CACG) coexisting with cataract.METHODS:This prospective, randomized study included 41 eyes with CACG. One-site approach was performed in 21 eyes and two-site procedure in 20 eyes. Intraocular pressure (IOP), best-corrected visual acuity (BCVA), the number of antiglaucoma medications and complications were observed. All patients were followed up for 9 months.RESULTS:There were no significant differences between the two groups preoperatively. IOP decreased from 22.7±4.9mmHg and 23.7±4.7mmHg preoperatively in one-and two-site groups to 18.0±1.2mmHg and 16.7±1.1mmHg 9 months after operation respectively(P<0.05). There were no significant differences in mean IOP between the two groups at any time (P>0.05). Decrease of the number of antiglaucoma medications and BCVA improvement were similar in both groups 9 months after surgery (P>0.05).There were no significant differences in complications between the two surgical procedures.CONCLUSION:There were no significant differences between the two groups in clinical efficacy and complications.

Objective · To establish human cervical cancer xenografts in nude mice and investigate the antitumor therapeutic effects and safety of EGF modified cisplatin-alginate conjugate liposomes. Methods · Cervical cancer-bearing mouse model was established by subcutaneously injecting Hela cells in nude mice. Generalstate and xenograft growth of the mice were observed. Tumor volumes, tumor weights, and the body weights of mice during the treatment were recorded and analyzed. The expression levels of EGFR in xenografts were detected by immunohistochemistry. Results · ① EGFR was highly expressed in the xenografts. ② CS-EGF-Lip inhibited the tumor growth effectively (P=0.000). ③ The inhibition rates of tumor volume and tumor weight of CS-EGF-Lip were 80.22% and 58.60% respectively, which were betterthan those of cisplatin (P=0.000). ④ CS-EGF-Lip had minimal influence on body weight in mice (P=0.000). Conclusion · CS-EGF-Lip has more effective antitumoreffects than cisplatin in cervical cancer-bearing mice, which can inhibit tumor growth of solid tumors with enhanced efficacy and safety.

Ischemic stroke has the characteristics of high morbidity and high mortality, which seriously endanger human health.According to the statistics, ischemic stroke in China accounts for about 80% of stroke cases, and its mortality rate is as high as 50%, but most of the ischemic stroke patients who survive have sequelae, such as hemiplegia, aphasia and so on.In recent years, people have continuously studied the pathological cascade of ischemic stroke, and also achieved some good results in animal model experiments, however, the clinical results are not satisfactory. Nowadays, the better clinically effective therapeutic drug is tissue plasminogen activator, but due to the limited time window,only a small number of patients can apply this drug in time to achieve the effect.Therefore,it is essential to study drugs that are definitive and can benefit a large number of patients with ischemic stroke.The development of traditional medicines is not as fast as the development of new drugs. For ischemic stroke,we can also turn from the study of the pathogenesis of ischemic stroke to the study of traditional drugs for the endogenous neuroprotection of ischemic stroke, and look for effective targets for neuroprotection based on traditional medicine.The multi-targets and multi-effects for the acute and convalescent phases of ischemic stroke is a direction explored by researchers, which also provides some evidence for more effective drugs for the treatment of ischemic stroke.
