International Eye Science 2014;(7):1325-1326
AlM: To observe the postoperative intraocular pressure ( lOP) and operation safety in the eyes of the neovascular glaucoma pateints treated by intraocular cyclophotocoagulation which needed vitrectomy at the same time.
METHODS: A total of 12 neovascular glaucoma cases ( 14 eyes ) secondary to diabetic retinopathy, retinal detachment surgery and trauma were reviewed in our study. This procedure mainly used intraocular photocoagulation catheter to highlight the ciliary processes until the ciliary became white atrophy or plosion after vitreous surgery treatment. The intraocular photocoagulation catheter was performed at a power of 300-500mW, for a duration of 0. 1-0. 2ms. Postoperative follow-up was at least for 6mo. The observation of 14 postoperative neovascular glaucoma was performed at 1wk, 1, 6mo observing the lOP and complications.
RESULTS:lOP of the 11 eyes was significantly declined and controlled in normal. After cyclophotocoagulation, average lOP at 1wk was 16. 7±14. 4mmHg, 15. 7±8. 8mmHg at 1mo and 12. 9±4. 5mmHg at 6mo, which compared with untreatment ( 39. 6 ± 10. 0mmHg ) was statistically significant different (P<0. 01). ln follow up time 3 cases were relapsed which were supplied with transscleral or endoscope cyclophotocoagulation. During the follow-up period no endophthalmitis and complications such as eyeball atrophy were found.
CONCLUSlON: The intraocular cyclophotocoagulation and vitrectomy simultaneously can deal with the primary disease and secondary neovascular glaucoma. The operation can be accurately performed under direct cyclophotocoagulation and it is a safe and effective way for neovascular glaucoma which needs vitreous surgery.

Objective To investigate the molecular mechanism underlying lymphocyte functionassociated antigen-1 (LFA-1) / intercellular adhesion molecule-1 (ICAM-1) mediated anti-neoplastic effects of cytokine induced killer (CIK) cells. Methods Lymphocytes isolated from peripheral blood of children leukemia were induced with interferon-gamma (IFN-y), anti-CD3 monoclonal antibody (CD3McAb) and interleukin-2 (IL-2) and co-cultured with dendrite cells (DC) to generate DC-CIK cells. When treated with LFA-1 monoclonal antibody, cytotoxicity of DC-CIK cells against leukemia cell lines was measured by the MTT assay, while RT-PCR and Western blotting were used to determine mRNA and protein expressions of GATA-3 and T-bet in DC-CIK cells, respectively. IL-12, IFN-γ and tumor necrosis factor-α (TNF-α) levels released by DC-CIK cells were quantified by ELISA. Results Induced DC-CIK cells were regular, round and transparent with variable cell volume and cellular aggregation. When treated with mouse anti-human LFA-1 monoclonal antibody, the cytotoxicity decreased mostly towards B95 cells under administration of 20 μg/ml LFA-1 monoclonal antibody in comparison with the control group(t =10.138, P <0.05). It led to a highest elevation of GATA-3 mRNA and protein levels (t =16.386, P < 0.05; t =22.652, P < 0.05) and a most decrease of T-bet mRNA and protein levels (t =17.728, P <0.05; t =17.452, P <0.05) under 20 μg/ml LFA-1 monoclonal antibody in B95 cells group in comparison with the control group. The expression levels of IL-12,IFN-γ, and TNF-o in supernatant were the lowest under 20 μg/ml LFA-1 monoclonal antibody in B95 cells group in comparison with the control group (t =21.621, P <0.05; t =13.739, P <0.05; t =15.278, P <0.05).Conclusion GATA-3 and T-bet were implicated in the LFA-1/ICAM-1 mediated anti-neoplastic effects of DC-CIK cells via activation of the Th1 pathway, with high secretion of Th1 cytokines, such as IL-12, IFN-γ and TNF-α.

Objective To detect the levels of plasma N-terminal pro-brain natriuretic peptide (NT-proBNP) and investigate its relationship with liver function, ascites and heart structure in patients with liver cirrhosis. Methods The levels of plasma NT-proBNP and various clinical and biochemical parameters were determined in 60 patients with liver cirrhosis and 30 healthy controls. Meanwhile Child-Pugh liver function was classified. All people underwent color Doppler echocardiography. Results The level of plasma NT-proBNP was significantly elevated in patients with liver cirrhosis [(38.63±36.05)pmol/L], compared with that of the controls [(7.50±8.25)pmol/L],P<0.01. There was no significant difference in different Child-Pugh class and aseites amount of liver cirrhosis. E/A < 1 and E wave decelerate time (EDT) was in-creased in liver cirrhosis. Conclusion The levels of plasma NT-proBNP in liver cirrhosis are significantly elevated, and related to early impairment of diastolic function. But it does not correlate with liver function and aseites.
