AIM:To discuss the application effect of adjustable sutures in glaucoma filtering operation after trabecular resection.
METHODS: Seventy-eight cases ( 101 eyes ) suffered from glaucoma were randomly divided into two groups, observation group and control group. Thirty-nine cases ( 51 eyes ) in the observation group underwent trabeculectomy with adjustable sutures, the control group (39 cases, 50 eyes) only adopted trabeculectomy.RESULTS: Compared Preoperative IOP in two groups, the difference was not statistically significant (P>0. 05). After 6mo, IOP were decreased compared with preoperative in two groups, and that in observation group was lower than control group, the difference was statistically significant ( P < 0. 05 ). Six months after operation, there were 1 eye with shallow anterior chamber Ⅰ and 2 eyes with non- functional bleb in observation group, and the complication rate was 5. 9%. While there were of 6 eyes with shallow anterior chamber, in which 4 eyes at gradeⅠ, each one at gradeII and Ⅲ. Non-functional blebs in 5 eyes and a scleral flap adhesion complications rate in the control group was 24. 0%, significantly higher than that in the observation group, the difference was statistically significant ( P<0.01).
CONCLUSION: The adjustable sutures combined with trabeculectomy for glaucoma can significantly reduce the postoperative complications. The curative effect is exact and clinically applicable.

Objective To explore the effect of budesonide(BUD) on dendritic cell(DC) and airway inflammation in the asthmatic mice.Methods Forty female Kunming mice were divided into 4 groups:asthmatic model group,therapeutic control group,BUD treated group,and normal control group,with 10 mice in each group.Mice were sensitized by an intraperitoneal injection of 50 ?g ovalbumin(OVA) adsorbed to 1 mg aluminum hydroxide dissolved in 0.2 mL saline.Animals were boosted on the 14th day in the same way.From the 21th to 35th days,and mice were challenged with 10 g/L aerosolized OVA for 30 min a day to establish a murine model of asthma.To evaluate the effect of BUD,60 minutes prior to OVA exposure,the mice were treated with 1 mg aerosolized BUD or placebo(saline).Control animals were sensitized intraperitoneally with saline and challenged with aerosolized saline alone.Eosinophil(EOS) count,degree of mucus secretion and DC count around the airways were measured by haematoxylin and eosin staining,periodic acid schiff's staining,immunochemistry technique and computerized image analysis system.Results In asthmatic model group,EOS count,DC count and the degree of mucus secretion around the airways were increased compared with nomal control group(P_a0.05).In BUD treated group,EOS count,DC count and the degree of mucus secretion around the airways were decreased compared with the asthmatic model group(P_a

Objective To investigate the proliferation and identification of dendritic cells(DC)de- rived from peripheral blood of patients with bladder cancer in vitro.Methods The mononuclear cells were prepared from peripheral blood of patients with bladder cancer by Ficoll-Hypaque centrifugation method,and were induced by the recombinant cytokines hGM-CSF(50 ng/ml),hlL-4(10 ng/ml)and hTNF-?(50 ng/ ml)for 2 weeks.The growth and morphology of DC were observed through the phase contrast or electron mi- croscope,and their pheuotypes were determined by flow cytometry.The capacity of DC to activate T cell-de- pendent anti-tumor immune responses was tested by MTT method.Results The DC cultured in vitro turned into suspensive growth from adhesive situation on the 6th day,then the number of DC increased con- tinuously and the cells showed the irregular morphologic appearance of DC with veiled edges on the 8th day. Flow cytometry showed that the mature DC expressed high levels of specific markers such as CD_(1a),CD_(83), CD_(86)and HLA-DR.T cells activated by DC showed strong cytotoxicity to bladder cancer cell line BIU87 with a killing rate of(48.8?3.7)%,while the killing rate of T cells which were not activated by DC was(25.7?1.5)%;the difference of the rate between them was significant(P＜0.01). Conclusions The DC can be cultured from peripheral blood of patients with bladder cancer by induction of rhGM-CSF,rhIL-4 and hT- NF-?in vitro.This may lay an experimental foundation for further research on DC vaccine.

Objective To investigate the effect of fluoride on the expression of a subunit of calcium/calmodulin-dependent protein kinase- Ⅱ (α-CaMK Ⅱ ) at both mRNA and protein levels in human neuroblastoma cells were cultured in DMEM with final concentrations of NaF 0(control) ,0.05,0.50,2.00,5.00 mmol/L, respectively, for 48 hours. Then quantitative RT-PCR and Western blot were performed to detect the expression level of α-CaMK Ⅱ P1 (postnatal day 1) pups together with their mothers were randomly divided into three groups. Lactating rats were given drinking water containing NaF at concentrations 0(control) ,2,3 mmol/L. And pups were exposed to NaF through milk. In each group, 8 pups were sacrificed on day 14 after birth. In post-weaning period, another 8 pups in each group were given drinking water with the same dose of fluoride as their mother's 21 day after birth. After then, these pups were killed on day 28, and hippocampus was dissected immediately and Western blot was conducted mRNA and protein levels were decreased. When NaF concentrations were 0,0.05,0.50,2.00,5.00 mmol/L, the mRNA relative ratios of α-CaMKⅡ in SY5Y cells were 1.00 ± 0.00,0.77 ± 0.18,0.40 ± 0.11,0.22 ± 0.06 and 0.15 ± 0.03, and protein levels of α-CaMK Ⅱ were 100.00 ± 0.00,76.17 ± 2.08,59.16 ± 2.12,48.52 ± 2.71 and 43.51 ± 2.57, any mmol/L group, hippocampus α-CaMK Ⅱ protein levels on day 14 and 28(75.02 ± 2.88,73.83 ± 3.88 and 81.00 ± 2.54,45.70 ± 2.34) were significantly lower than that of control groups(100.00 ± 0.00,100.00 ± 0.00, all P < 0.01). In 3 mmol/L group, hippocampus α-CaMKⅡ protein level on day 28 was lower than that of 2 mmol/L group (P < 0.01). Conclusion Fluoride can decrease mRNA and protein levels of α-CaMK Ⅱ in nerve cells and hippocampus, which may be one of the mechanisms of learning and memory impairment by fluorosis.
