AIM: To explorethe therapeutic efficacy of treating cataract phacoemulsification remove combined with trabeculectomy early postoperative failure with open sclera flap recanalization by phacoemulsification auxiliary hook interred the anterior chamber.
METHODS:Twenty-seven cases ( 27 eyes ) of glaucoma combined cataract surgery(3mo) in the early failure were treated with that the phacoemulsification auxiliary hook into anterior chamber under the original sclera flap, open from the inside have adhesion of the sclera flap. Postoperative follow-up 12mo, the intraocular pressure and best corrected visual acuity were observed.
RESULTS: The postoperative follow- up was 12mo. There were functional filtering bleb in 14(52%) eyes; and the IOP was below 21mmHg in 17 eyes(63%) without any anti- glaucoma drug, and in 7 eyes ( 26%) with 1 - 2 categories of lower intraocular pressure( IOP) drugs, and 3 eyes(11%), failure and the success rate was 89% after 12mo. Average intraocular pressure after 1wk, 1mo, 3mo, 6mo and 12mo were(7. 1±4. 3) mmHg,(10. 5±5. 1) mmHg,(15. 1±4. 8 ) mmHg, ( 16. 8±5. 2 ) mmHg, ( 17. 3±5.1 ) mmHg, significantly lower than the IOP preoperatively(30. 2±6. 8) mmHg (P<0. 01). Average visual acuity ( all of the following were best corrected vision) after 1wk, 1mo, 3mo, 6mo and 12mo was(0. 32±0. 52),(0. 52±0. 42),(0. 55±0. 39),(0. 53±0. 47),(0. 54±0. 42 ). Postoperative 1wk visual acuity deeper than preoperative( 0. 46 ± 0. 44 ) ( P < 0. 05 ), more than all improved compared with preoperative ( P < 0. 05 ). Postoperative anterior chamber bleeding in 5(19%) eyes, all absorbed itself in 3 to 5 days; ciliochoroidal detachment in 7 ( 26%) eyes, except one case need operate, others were conservative treatment to heal. Postoperative continuous low intraocular pressure concurrent macular edema was 1 eyes(4%), 4mo healed after treatment.
CONCLUSION: It is a safe and effective method thattreating phacoemulsification cataract remove combined with trabeculectomy early postoperative failure with open sclera flap recanalization by phacoemulsification auxiliary hook interred the anterior chamber.

The present study is to establish Caco-2/HT29-MTX co-cultured cells and investigate the transport capability of PLGA nanoparticles with different surface chemical properties across Caco-2/HT29-MTX co-cultured cells. PLGA-NPs, mPEG-PLGA-NPs and chitosan coated PLGA-NPs were prepared by nanoprecipitation method using poly(lactic-co-glycolic acid) as carrier material with surface modified by methoxy poly(ethylene glycol) and chitosan. The particle size and zeta potential of nanoparticles were measured by dynamic light scattering. Coumarin 6 was used as a fluorescent marker in the transport of nanoparticles investigated by confocal laser scanning microscopy. The transport of furanodiene (FDE) loaded nanoparticles was quantitively determined by high performance liquid chromatography. Colchicine and nocodazole were used in the transport study to explore the involved endocytosis mechanisms of nanoparticles. Distribution of the tight junction proteins ZO-1 was also analyzed by immunofluorescence staining. The results showed that the nanoparticles dispersed uniformly. The zeta potential of PLGA-NPs was negative, the mPEG-PLGA-NPs was close to neutral and the CS-PLGA-NPs was positive. The entrapment efficiency of FDE in all nanoparticles was higher than 75%. The transport capability of mPEG-PLGA-NPs across Caco-2/HT29-MTX co-cultured cells was higher than that of PLGA-NPs and CS-PLGA-NPs. Colchicine and nocodazole could significantly decrease the transport amount of nanoparticles. mPEG-PLGA-NPs could obviously reduce the distribution of ZO-1 protein than PLGA-NPs and CS-PLGA-NPs. The transport mechanism of PLGA-NPs and mPEG-PLGA-NPs were indicated to be a combination of endocytosis and paracellular way, while CS-PLGA-NPs mainly relied on the endocytosis way. PEG coating could shield the surface charge and enhance the hydrophilicity of PLGA nanoparticles, which leads mPEG-PLGA-NPs to possess higher anti-adhesion activity. As a result, mPEG-PLGA-NPs could penetrate the mucus layer rapidly and transport across Caco-2/HT29-MTX co-cultured cells.

In this paper, three higher content of flavonol glycosides from the stems and leaves of Tribulus terrestris L. were determined by reversed phase HPLC. The results showed that there was good liner relationship between the peak areas and the sample concentration at the ranges of 0.011 2~0.280 0 μg (r=0.999 6), 0.064 8~2.592 0 μg (r=0.999 8) and 0.018 4~0.460 0 μg (r=0.999 8) for isorhamnetin-3-O-β-D-gentiobioside-7-O-β-D-glucoside, quercetin-3-O-β-D-gentiobioside and isorhamnetin-3-O-β-D-gentiobioside respectively. The verage recovery rates (n=9) of three flavonol glycosides compounds were 100.15%(RSD=1.32%), 100.02% (RSD=1.14%), 99.77% (RSD=1.16%), respectively. This method is considered to be simple, accurate, stable, good precision and reproducibility, which is available for the quality control and evaluation of T. terrestris L.

Objective To investigate changes in CD_4~+ CD_(28)~(null)T cell numbers of peripheral blood and the expression of perforin in patients with coronary heart disease.Methods Sixty-eight patients with acute coronary syndromes,56 with stable angina and 65 healthy subjects were enrolled in the study.CD_4~+ CD_(28)~(null)T lymphocytes were measured by flow cytometric analysis.Results The numbers of CD_4~+ CD_(28)~(null)T lymphocytes in patients with acute coronary syndromes were higher than those in patients with stable angina and in the control subjects(11.6 % vs 2.84% and 0.59%,P

To investigate the effect of NVP-DPP728, a DPP-Ⅳ inhibitor on new-onset diabetes and the autoimmune response in non-obese diabetic ( NOD ) mice. Diabetes could be reversed in 75% of NVP-DPP728 treated 20 NOD mice. In these 15 mice with remission, insulitis scores were significantly lower than those of the control group. The percentage of Tregs was increased in the thymus and celiac lymph nodes, plasma TGF-β1 and GLP-1 were also significantly increased ( P＜0. 01 ). NVP-DPP728 treatment may reverse new-onset diabetes in NOD mice by reducing insulitis and increasing Tregs.
