Dry age-related macular degeneration(AMD)is a prevalent form of irreversible blindness worldwide in the elderly population with an increasing incidence in China.It is found that some dry AMD will develop to wet AMD and therefore damage visual function.Pathogenesis of AMD is below understand now,but it is thought to be related to the light-induced ocular damage,oxidative stress response,extracellular disposition and immunology.Up to now,effective and safe prevention and treatment methods of AMD are still studying,especially wet AMD,but the concern on dry AMD is not enough.Some basic and clinical pharmaceutics researches on AMD include antioxidants,anti-extracellular disposition drugs and anti-inflammatory agents.With the rise of aging population,we should pay special attention to the research on pathogenesis,diagnosis and treatment of dry AMD.

Vitreo-retinal surgery is one of the effective methods in treating severe vitreoretinopathy.However,there remains great variance in surgical quality,outcomes and success rates among hospitals of different areas in China.This article focuses on how to im- prove in surgical outcomes and success rate as well as to avoid complications of vitreo-retinal surgery.Specific issues are addressed on such as indications and timing of vitreo-retinal surgery,management of pre-operative patients,applications of new appliances and mate- rials,maneuver of surgical techniques and nurturing appropriate habits of surgery.

This study is to establish the gastric cold model of rats. After gastric feeding with cold water for 5 weeks and extra iced water bath in the last 2 weeks, model group show distinct physical sign of gastric cold syndrome. The pathology of gastrics reveals gastricism of model group, while treatment group(treated with Fanzuojin Wan) show mild lesion. Elisa detection of model group show that the solution of interleukin-2 (IL-2) is higher than blank group. The difference with significance among model group, treatment group and blank group reveals the success of the establishment of gastric cold syndrome.

This study is to establish the gastric hot model of rats. After gastric feeding with ethanol solution for 3 weeks and feeding with extra capsaicin and ethanol solution for another 2 weeks, model group show distinct physical sign of gastric hot syndrome. The pathology of gastrics reveals gastricism of model group, while treatment group (treat with Zuojin Wan) shows mild lesion. Elisa detection of model group show that the solution of interleukin-2 (IL-2) is higher than the blank group. The obvious difference among model group, treatment group and blank group reveals the success of the establishment of gastric hot model.

Based on the analysis of current condition of local medical schools and medi-cal talents demand at the grassroots level,this paper indicates that,taking students’personality development as a breakthrough point,with practice platform construction as main part,supple-mented by multi-knowledge hierarchy and scientific and cultural exposure,backed by workable policy.

Objective To explore the clinical significance of T lymphocyte subsets and NK cells' detection in peripheral blood of patients with non-Hodgkin' s lymphoma (NHL).Methods 62 newly diagnosed NHL and 30 healthy adults were enrolled for analyzing.T lymphocyte subsets and NK cells were deteced by flow cytometry and compared between different groups according to age,sex and pathology.Multiple linear regression was used to analyze the correlation among the levels of T lymphocyte subsets and NK cells and several clinical factors,such as clinical stage,IPI and B symptoms.Results The proportions of CD3,CD4 and NK cells in peripheral blood of NHL group [(64.13±19.83) ％,(27.10±8.20) ％,(13.51± 10.59) ％] were significantly lower than those of normal control [(65.78±10.69) ％,(31.95±12.74) ％,(18.76± 7.36) ％] (P ＜ 0.05),while the proportions of CD8 and Treg cells in peripheral blood of NHL [(32.15±13.83) ％,(10.44±3.00) ％] were significantly higher than those of normal control [(29.25±12.35) ％,(7.51±4.36) ％] (P ＜ 0.05).In NHL,the proportions of CD3 and NKT cells [(67.06±19.24) ％,(4.91±3.69) ％] in ≤60 years old group were significantly higher than those in ＞ 60 years old group [(59.18±20.33) ％,(4.89±3.05) ％] (P ＜ 0.05).The proportions of Treg cells in T-NHL was significantly higher than that in B-NHL [(8.17±6.41) ％ vs (7.11±2.53) ％] (P ＜ 0.05).The proportions of CD3,CD4,NK and NKT cells in peripheral blood of NHL were significantly correlated with clinical stage (P ＜ 0.05),that of CD8 cells were significantly correlated with IPI (P =0.000),that of Treg cells were significantly correlated with IPI and B symptoms (P ＜ 0.05).Conclusion The cellular immune is suppressed in NHL patients.The proportions of T lymphocyte subsets and NK cells in peripheral blood of patients with NHL are different between different groups according to age,sex and pathology.The correlations among that and clinical factors need to be further explored.
