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.

Background The special pathological change of diabetic retinopathy(DR)is microvascular disorder.Angiopoietin-like protein 2(Ang-2)is a new protein associated with genesis of blood vessels.Quercetin has multiple pharmacological action,including improving the microcircularion and the permeability of blood capillary.However,the action mechanism of Ang-2 on DR was unclear.Objective The present study was to investigate the effects of quercetin on Ang-2 and its receptor Tie2 expression in retina with diabetes mellitus.Methods Sixty clean male Wistar rats were randomized into 7 groups and 10 rats for each group,and 10 rats served as blank control group.Streptozotocin of 35 mg/kg was intraperitoneally injected in 60 rats to establish the diabetic models.Quercetins encapsulated by liposome with the doses of 50,150 and 250 mg/(kg · d)(3-5 ml)were used to gavage in different groups of models for 12 weeks,and normal saline solution and calcium dobesilate were used at the same fashion as the negative control group and positive control group,respectively.Twelve weeks later,the animals were sacrificed and retinas were isolated.Expressions of Ang-2 protein and Tie2 mRNA in retinas were detected by ELISA and RT-PCR,respectively.The usage and rearing of the animals complied with the Regulations for the Administration of Affair Concerning Experimental Animals by State Sciences and Technology Commission.Results ELISA showed that the A450 of Ang-2 in 150 and 250 mg/(kg · d)quercetin groups was 0.796±0.057 and 0.842±0.043 respectively and was lower than that negative group(1.012±0.046),showing statistically significant differences(q =2.95,2.698,P＜0.05).RT-PCR assay showed that expression of Tie2 mRNA(Tie2 mRNA/GAPDH mRNA)in retinas was 0.712±0.092 and 0.821±0.087,presenting statistically significant differences in comparison with negative group(1.182±0.098)(q =3.497,2.852,P＜0.05).The expression levels of Ang-2 and Tie2 mRNA in retina were lowest in 150 mg/(kg · d)quercetin group.Conclusions Quercetin can improve the retinal microcirculation by downregulating the expressions of Ang-2 and its receptor in early period of diabetic rats.

OBJECTIVETo improve the diagnosis and treatment of penile metastasis from rectal carcinoma.

METHODSWe reported a case of penile metastasis secondary to rectal adenocarcinoma, reviewed the relevant literature, and discussed the common origins, clinical features, pathogenic mechanisms, diagnosis and treatment of this disease.

RESULTSThe patient was a 54-year-old male, with metastatic penile tumors secondary to rectal adenocarcinoma, with serious adhesion to the surrounding tissue and metastasis to the liver. As treatment, we performed colostomy to relieve voiding difficulty, followed by combination chemotherapy with oxaliplatin, 5-fluorouracil, and levofolinate. The patient died 10 months later as a result of systemic failure.

CONCLUSIONPenile metastatic malignancy has a poor prognosis. Early diagnosis and combined and individualized therapies may improve the quality of life, relieve pain and prolong the life of the patient.
