Objective　To analysis the relation of the diameter of continuous curvilinear capsulorhexis and other factors with the capsular block syndrome.Methods　We not only analyzed the etiology and clinical characteristic of six cases in intraoperative,early postoperative and lately postoperative,but also discussed the method of treatment.Results　(1)When the diameter of CCC was smaller than the one of IOL's optic , the CBS easily happened; (2)When the hoops of the hydroview IOL had a smaller anterior angle and larger optic, the CBS easily happened; (3)When the viscoelestic material and cortex were stayed in capsular or anterior chamber, the CBS easily happened.Conclusion　(1)Generaly speaking the size of the CCC should right on the edge of the IOL's optic part; (2)To hydroview IOL, we should choose the one which had a larger anterior angle and a smaller optic; (3)Viscoelastic material which should be cleaned and there was no the rest cortex stayed in the capsular.

Objective To evaluate the application of Snodgrass urethroplasty for failure hypospadias repairment.Methods Eighty-four cases of failure hypospadias were treated by Snodgrass urethroplasty from 2001 to 2005.The average age of patients was 3.7 years old.In the meantime,Duplay procedure was undertaken for other failure hypospadias with enough penile skin(76 cases).Results There were 64 cases cured,6 cases with urethral stricture and 14 cases with urethral fistula in 84 failure hypospadias cases.Sixty-one cases were cured in 76 cases used Duplay procedure.Conclusion Snodgrass is recommended for failed hypospadias cases with narrow urethral plate.

Objective To assess the clinical efficiency and side effects of topical mometasone furoate aqueous nasal spray for patients with naphazoline-induced rebound rhinitis. Methods A prospective, non-randomized and self-controlled study was applied. A total of 22 patients with naphazoline-induced rhinitis received two spray-puffs of 50 μg mometason furoate twice daily to each nostril in the morning for one week, followed by two spray-puffs of 50 μg mometason furoate once daily to each nostril every morning for another three weeks after withdrawn of naphazoline therapy. Nasal congestion was evaluated by visual an-alogue scale (VAS) recorded before and after treatment. Side effects like nose bleeding and perforation of the nasal septum was detected with rhinoscope. Results The statistical difference of VAS before and after treatment was significant. No adverse reac-tions as nose bleeding and perforation of the nasal septum were observed by the end of treatment. Conclusion It is safe and effective to use mometasone furoate aqueous nasal spray for treating rebound rhinitis induced by misuse of naphazoline nasal drop.

Objective:To quantitively detect TfR gene expression of human white blood cell before and after iron supplementation. Methods:Before and after iron supplementation,10 healthy women were phlebotomized separately,and the real-time fluorescence quantitative PCR method was used to analyze the expression difference of TfR gene in human white blood cell. Results:TfR gene expression decreased after iron supplementation in 10 women,more evidently in 7 cases,where the expression level was half less than before iron supplementation. Conclusion:TfR gene expression of human white blood cell could be quantitatively measured by FQ-PCR,and was decreased after iron supplementation in 10 women. It explained that the regulative mechanism of TfR mRNA expression by iron is also suitable to white blood cell.

OBJECTIVE:To study the cost-effectiveness of4dose regimens in treating chronic prostatitis/chronic pelvic cavity pain syndrome(CP/CPPS).METHODS:A total of140patients with CP/CPPS were randomly divided into4groups:Baiyanjing tablets and tamsulosin hydrochloride modified release capsules were administered for Group A;minocycline micro pills and alfuzosin retard tablets for Group B;rexithromycin tablets and doxazosin mesylate controlled release tablets for Group C;and levofloxacin tablets and terazosin tablets for Group D.The cost-effectiveness analysis was performed using pharma?coeconomics.RESULTS:The costs for the Group A,B,C and D were268.8yuan,641.8yuan,660.8yuan and666.4yuan,respectively.The effective rates were71.4%,91.4%,88.6%and91.4%,respectively.The cost-effectiveness ratios were3.76,7.02,7.46and7.29,respectively.The incremental cost-effectiveness ratios of Group B,C and D were18.65,22.79and19.88,respectively as against Group A.CONCLUSION:The treatment cost of CP/CPPS was composed of2parts:an?tibiotics? 1 -receptor blockers.Doctors should make an optimum choice based on patients'previous medication,economic status and physical condition,etc.

Objective To study the protective effect of(-)clausenamide on the damage of PC12 cells induced by serum deprivation and to explore its related mechanism. Methods The cell viability was detected by MTT assay and morphological observation. The effect of(-)clausenamide on the PC12 cell apoptosis was analyzed by flow cytometry. Then western blotting and confocal microscope was used for the further study of effect of(-)clausenamide on the protein expression of GSK-3?,Bax and Bcl-2. Results(-)Clausenamide remarkably increased PC12 cell survival rate through inhibiting the PC12 cell apoptosis induced by serum deprivation at the concentration of 1 or 10 ? mol/L(P

Background Dacryocystitis is one of the most common infectious eye diseases.The gold standard for the identification of bacteria causing dacryocystitis is bacterial culture.The combination of regular culture method with molecular biology techeniques will generate more reliable results.However,very few research data are available in ophthalmological studies in this area.Objective This study was to identify the genera and species of the dacryocystitis-causing bacteria by PCR amplification of the 16S rRNA sequences.Methods Ten cases of qualified standardized bacteria samples were taken,and the nucleic acids were released in the heating process of the PCR procedure.The 16S rRNA genes were amplified and sequenced,and the genera and species were identified using BLAST from GenBank,and the results were used to compare with the results from biochemical identification to test the reliability of this method.The cultured bacterial species from the lacrimal sac secretions from 30 cases of dacryocystitis patients were identified with the above method.Results The outcome of the PCR identification for the 10 cases of quality control standard bacterial specimens was consistent with the results from the biochemical identification.The identification of the 30 cases of dacryocystitis through sequencing the 16S rRNA revealed there were 13 cases of Staphylococcus epidermidis infection,2 cases of Staphylococcus warneri infection,1 case of Staphylococcus hominis infection,5 cases of Corynebacterium macginleyi infection,3 cases of Streptococcus pneumonia infection,2 cases of Bacillus cereus infection,1 case of Micrococcus luteus infection,1 case of Moraxella catarrhalis infection,1 case of Moraxella osloensis infection and 1 case of Pseudomonas aeruginosa infection.Conclusions Sequencing the 16S rRNA is an accurate and specific way for the identification of the genera and species of bacteria that cause dacryocystitis in patients.This sequencing method is feasible in monitoring a variety of dacryocystitis-causing pathogens.More information and epidemiological statistics about dacryocystitis can be obtained from 16S rRNA sequencing.

Objective To observe temporal expression of matrix metalloproteinases(MMP-13) and tissue inhibitor of metalloproteina-ses-1 (TIMP-1) in lung of newborn rats with hyperoxia induced chronic lung disease (CLD),and to explore the relationship of CLD with MMPs.Methods The neonatal rats within 24 hours after birth were randomly divided into hyperoxia-exposed group(n=40) and control group(n=40).On postnatal 1,3,7,14 and 21 days,lung tissue of rats in 2 groups were collected.Lung histological changes were evaluated by hematoxylin and eosin and Masson stain;Collagen Ⅰ was detected by enzyme linked immunoadsorbent assay;MMP-13 and TIMP-1 were identifide by immunohistochemistry.Results Exposured to hyperoxia enviroment for 21 days,the number of alveolar decreased,terminal air space enlarged,inter-alveolar septa thickened,and deposition of interstitial collagen fibers.On 14 and 21 days,collagen Ⅰ in the lung of hyperoxia-exposed group increased significantly compared with that of control group(P0.05),obviously decreased on 21 day(P
