BACKGROUND: Cervical lymph nodes are draining region of cornea. It is believed that aqueous fluid goes through a minor pathway named uveoscleral drainage, which will allow passage of antigen-presenting cells (APC) directly to the draining lymph nodes and induce allograft rejection after keratoplasty.OBJECTIVE: To explore the inhibitory effects of cervical lymphadenectomy in alkali induced high-risk corneal transplantation.DESIGN: A randomized controlled animal experiment.SETTING: State Key Laboratory of Ophthalmology, Zhongshan Ophthalmic Center, Sun Yat-sen University.MATERIALS: The experiment was performed in the State Key Laboratory of Ophthalmology (No. 2006DA105054), Zhongshan Ophthalmic Center, Sun Yat-sen University from May 2005 to February 2007. 144 male animals (1-2 months old) including 104 SD rats and 40 Wistar rats were provided by the animal experimental center of Sun Yat-sen University. Sandwich enzyme-linked immunosorbent assay (ELISA) kits for interleukin-2 (IL-2) and interferon-γ (IFN-γ) were brought from BioSource International company (USA). The animal treatment in the experiment was accorded with the statement in Association for Research in Vision and Ophthalmology (ARVO) for animals.METHODS: With the SD rats as recipients, and Wistar rats as donors, all rats were subjected to corneal allografting. The recipient rats were randomly divided into 4 groups (n=20): group A (control group) which underwent corneal transplantation; group B which was subjected to bilateral cervical lymphadenectomy; group C, corneal transplantation 21 days after the alkali burn injury; group D, cervical lymphadenectomy following group C. The immune rejection of grafts was evaluated by detecting the expression of IFN-γ and IL-2 using ELISA. The time when allograft rejection occurred was recorded and mean survival time (MST) was compared among the groups. The development of corneal inflammation and new vessels was examined by slit lamp microscope and histopathological examination.MAIN OUTCOME MEASURES: ①The development of corneal inflammation after corneal alkaline burns. ②MST of rats in each group following transplant. ③The expression of IL-2 and IFN-γ in grafts of each group. RESULTS: ①Normal rat cornea was transparent without inflammation or neovascularization. There were many inflammatory cells invading to stroma on day 3 after burn. Then, the inflammation of cornea resolved gradually 3 weeks after the burn, but corneal neovascularization reached the peak at that time. Corneal blood vessels regressed completely at the end of 8 weeks after the burn. ②The MST of group A, B, C, and D was (10.40±1.14), (46.30±9.46), (7.00±1.58), and (15.00±3.39) days, respectively. Compared with the group A, the MST of group B was significantly longer (P < 0.05), and the MST of grafts in group D was also significantly longer than group C (P < 0.05). ③The expression of IFN-γ and IL-2 proteins was absent in group B. Compared with group C, the expression of IL-2 and IFN-γ proteins in group D significantly decreased on days 3, 7, 10, and 14 after keratoplasty (P < 0.05). CONCLUSION: Cervical lymphadenectomy therapy can effectively inhibit corneal allograft rejection in normal and high-risk corneal beds after alkali burn injury.

6.Vision 2020 and prevention of blindness: is it relevant or achievable in the modern era?
Annals of the Academy of Medicine, Singapore 2006;35(3):215-222
We are living in exciting times with many challenges and new opportunities to overcome diseases. The concept and definition of blindness and their major causes worldwide are discussed with reference to the Vision 2020 initiatives launched in 1999 for blindness prevention, with an updated summary. The peculiar problems that exists in Singapore are also presented. Yet, if the world's major causes of blindness: cataracts, onchocerciasis, trachoma, refractive errors and low vision, and childhood blindness (inherent problems of the Third and Fourth World) can be overcome with international concerted efforts by year 2020, there will emerge new causes as yet unknown. Noble as our aims may be to achieve short- and long-term targets, we have to face the continuous reality of our inability to fulfil them.

ObjectiveTo investigate the effects of different therapeutic methods on borderline hypertension with metabolic syndrome patients. MethodsNinety borderline hypertension with metabolic syndrome patients were divided into three groups by random digits table with 30 cases: control group,conventional therapy group and intensive therapy group. The control group was given regular observation, the conventional therapy group took drug according to the disease situation; and the intensive therapy group not only formulated the aim of therapy, but also received diet control, sport therapy, healthy education and drug therapy. After 1 year's follow-up, the patients' changes were compared. ResultsAfter 1 year's follow-up,the levels of FPG, 2 h PG, 24 h mAlb and IMT were significantly increased(P < 0.05 ), and the levels of other index had no significant changes (P> 0.05) in control group. The levels of FPG,2 h PG,TC and TG were significantly decreased and IMT was significantly increased(P <0.05), the levels of other index had no significant changes(P > 0.05 ) in conventional therapy group. The levels of SBP, DBP, PP, FPG, 2 h PG, TC,TG,hs-CRP,24 h mAlb and HOMA-IR were significantly decreased and HDL-C, ABI were significantly increased (P < 0.01 or < 0.05 ) in intensive therapy group. After treatment, the levels of ABI and H DL-C were significantly higher and SBP, DBP, PP,TG, hs-CRP, 24 h mAlb, HOMA-IR, IMT were significantly lower in intensive therapy group than those in conventional therapy group (P < 0.01 or < 0.05 ). ConclusionsDrug therapy is efficient in borderline hypertension with metabolic syndrome patients, and intensive therapy can obviously improve the insulin resistance, to control the developing of hypertension can delay the vascular

The stomatogastric ganglion (STG) of shellfish includes 30 neurons and produces pyloric rhythms. It is the common model to study central pattern generator (CPG). Regulation of pyloric rhythms not only is related to the property of single neurons in STG but also depends on the connections and property of the whole neuronal network. It has been found that transient potassium current (I(A)) and hyperpolarization-activated cation current (I(h)) exist in certain types of neurons of STG. However, roles played by these two currents in maintaining and regulating the pyloric rhythms are unknown. In the present study, in vitro electrophysiological recordings were performed on crayfish STG to examine the role played by I(A) and I(h) in regulation of pyloric rhythm. 4AP (2 mmol/L), a specific inhibitor of I(A), caused a decrease in pyloric cycle (P < 0.01), an increase in PD (pyloric dilator) ratio, a decrease in PY (pyloric) ratio (P < 0.01) and delay of phases of LP and PY firing. ZD7288 (100 μmol/L), a specific inhibitor of I(h), caused a decrease in pyloric cycle (P < 0.01), an increase in PD ratio (P < 0.01), an increase in LP (lateral pyloric) ratio (P < 0.01), a decrease in PY ratio (P < 0.01) and delay of phases of LP and PY firing. These results indicate that I(A) and I(h) play important roles in regulating pyloric rhythms in crayfish STG.
