Background The effectiveness of medical tissue adhesive for the reparation of operative incision has been recognized,but its influence to ocular surface microenvironment is not quite clear.Objective This study was to appraise the safety and efficacy of α-cyanoacrylate,a medical issue adhesive,for the reparation of the conjunctival and skin laceration.Methods Twenty healthy New Zealand rabbits were randomly divided into suturing group and medical glue group.Routine ophthalmic examination,the level of tear secretion and breakup time of tear film (BUT) were tested before operation.The upper bulbar conjunctiva of each right eye was cut apart about 1.0 cm after surface anesthesia and the skin of back was incised about 2.5 cm length after local anesthesia.The conjunctival and skin lacerations were adhered with compound medical adhesive in the medical glue group,and continuous suture was done to repair the conjunctival laceration and interrupted suture to the skin laceration with 5-0 chorda serica chirurgicalis in the suture group.The routine ophthalmic examination,level of tear secretion,BUT and the states of wound healing were examined 1 day,2 days and 7 days postoperatively.Pathologic examination of the corresponding tissues was also carried out 1 week after the animals were sacrificed.The data were analyzed by SPSS 13.0 statistical software.This experiment followed the Administration of the Care and Use of Experimental Animals of Shanghai City.Results The conjunctival and skin lacerations healed well both in the suture group and the medical glue group.The levels of tear secretion 1 day and 2 days postoperatively in the medical glue group were (12.70±2.21)mm and (12.70±2.00)mm respectively,showing a significant lowness in comparison with (14.90±2.38)mm and (14.90±2.33)mm of the suture group (q =-4.02,P =0.03;q =-4.02,P =0.03).Compared with the baseline,the difference of the levels of tear secretion in the medical glue group was not statistically significant in various time points after operation (P=1.00,1.00,0.51).The BUT values at 2 days and 7 days postoperatively in the medical glue group were (4.50 ± 1.18) seconds and (4.10±0.88) seconds respectively,being significantly longer than (3.30 ± 1.06) seconds and (3.00±1.25) seconds in the suture group (q=4.37,P=0.02;q=4.19,P=0.03).Compared with the baseline,there was not statistically significant difference at each time point postoperatively in the medical glue group (P =0.28,0.59,0.21).However,BUT at each time point after operation in the suture group was significantly shorter than that of the baseline (P=0.01,0.01,0.00).Pathological examination showed that all the conjunctival and skin lacerations healed well.Trivial collagen hyperplasy was seen in the eyes of the suture group and infiltration of a few of inflammatory cells was found in the medical glue group.In the pathological result of the skin test,there was conspicuous scar and severe collagen hyperplasy in the suture group,but in the medical glue group,the skin structure was almost normal.Conclusions α-Cyanoacrylate is safe and effective for the repair of the conjunctival incision with little affection to ocular surface microenvironment.

OBJECTIVE: Investigate common deafness gene mutations in patients with severe and profound non-syndromic hearing loss in Liaoning in order to understand their hereditary etiologies and characteristics at the molecular level. METHOD: Peripheral blood samples were obtained and the DNA templates were extracted from 128 non-syndromic hearing loss patients who are sporadic in clinics. The deafness gene chip was applied to detect hot-spot deafness gene mutations including GJB2, GJB3, SLC26A4 and mitochondrial 12S rRNA. Deafness etiology questionnaires, pure tone audiometry, auditory brainstem response, tympanometry and temporal bone CT were also applied. RESULT: Various types of gene locus mutations were seen in 52 of the 128 patients (40.6%); (1) GJB2 gene mutations (n=22) included c. 235 del C homozygous mutation (n=10), c. 235 del C heterozygous mutation (n=5); c. 176_191 del 16 heterozygous mutation (n=l); c 35 del G heterozygous mutation (n=l); c. 235 del C/c. 299_300 del AT mutation (n=l), c. 235 del C/c. 176_191 del 16 mutation (n=l), c. 35 del G/c. 176_191 del 16 mutation (n=l); c. 299_300 del AT/c. 919-2 A>G mutation (n=l), c. 235 del C/c. 919-2 A>G mutation (n=l). (2) SLC26A4 gene mutations (n=30) included c. 919-2 A>G homozygous mutation (n=6), c. 919-2 A>G heterozygous mutation (n=17), c. 2168 A>G homozygous mutation (n=l), c. 2168 A>G heterozygous mutation (n=2), c. 2168 A>G/c. 919-2 A>G mutation (n=2), c. 919-2 A>G/GJB2 c. 235 del C mutation (n=2); (3) No GJB3 and mitochondrial 12S rRNA mutation. Genetic deafness was confirmed at the gene level in 24 cases (18.8%) and 28 patients (21.9%) were diagnosed as carriers of genetic deafness gene mutations. CONCLUSION Genetic deafness occupies a large population in deaf community in Liaoning. Molecular genetic screening for these mutations and genetic counseling are effective methods to prevent the occurrence of hereditary hearing loss and provide theoretical guidance.

Objective To observe the effect of ciclosporin(CsA) treatment on children with refractory nephrotic syndrome(NS).Met-hods Combination treatment of CsA[3-5 mg/(kg?d)] and prednisone were given 55 cases with refractory NS,in which including steroid-dependent NS(SDNS) 3 cases,steroid-resistant NS(SRNS) 22 cases,frequent-relapses NS(FRNS) 30 cases.Concentration of CsA was maintained 100-200 ng/L.Course of treatment was 10 months,the dose was tapered gradually in 4 months.Scr,BUN,Alb,ALT,Ccr,Chol,24 hours urine protein quantitation was measured before and after CsA treatment.Side effect of CsA was observed at the same time.SPSS 13.0 software was used to analyze the data.Results Forty-one cases(74.5%) were complete remission,6 cases(10.9%) were partial remission,total effective rate was 85.5%.Remission rate was 97.6% in simple type NS,50.0% in nephritis type NS,100% in SDNS and FRNS groups,63.6% in SRNS group.In group minimal change disease(MCD),the remission rate was 100.0%,while 60.0% in group mesangial prolife-rative glomerulonephritis(MsPGN),and 42.9% in group focal segmental glomerulosclerosis(FSGS).Fifteen cases(31.9%) relapsed when the dose of CsA was tapering.The adverse effects included hairiness(55 cases),gum hypertrophy(16 cases),hypertension(9 cases),gastroi-ntestinal tract reaction(8 cases),but no obvious nephric adverse effects were observed during the treatment process.Conclusion CsA is safe and effective on refractory NS children,especially to those with SDNS,FRNS and MCD.

Objective: To assess the regional systolic and diastolic function of left ventricle by pulsed wave Doppler tissue imaging ( PW-DTI) in patients with coronary artery disease ( CAD ) . Methods : Seventy-seven cases of coronary angiography were adopted for study and grouped in terms of severity of coronary arterial lesion. Peak systolic, peak early diastolic, and peak late diastolic motion velocities (Sm, Em and Am, respectively) were recorded at 6 different sites on the basal and medial segments corresponding to the anteroseptal, posteroseptal, lateral, anterior, inferior, and posterior walls of the left ventricle with PW-DTI. Results: Am in segments corresponding to normal coronary arteries (group A) was lower than in segments corresponding to slightly stenosed coronaries (group B). There was no significant difference in Sm and Em between group A and group B. Compared with group A, Sm, Em and Am were significantly decreased in segments corresponding to severely stenosed coronary arteries ( group D). Conclusion : PW-DTI could be used to evaluate quantitatively and accurately the regional mvocardial function of left ventricle in patients with CAD.

OBJECTIVETo compare the osseointegration and corrosion of different kind of coatings on pure titanium.

METHODSBy plasma spraying technology, nitrogen silicon zirconium-hydroxylapatite (ZrSiN-HA) compound coating was prepared on the surface of pure titanium and the pure titanium was implanted with the mandible of the experimental animal. The superficial appearance of the compound coating was observed and analyzed by scanning electron microscope (SEM). The ZrSiN-HA, nitrogen silicon zirconium (ZrSiN), hydroxylapatite (HA) and pure titanium were compared and examined. In the four groups, the bone binding force of coatings were detected, and the superficial appearance of the break regions were observed by the electronic multipurpose material testing aircraft. In the four groups, the anticorrosive of coatings were compared and examined on the electrochemistry corrosion testing system.

RESULTSExperimental results indicated that the implant surface sprayed with the ZrSiN-HA was more compact than that sprayed with HA. The crystallization was obvious. Compared with the other coatings, the bone binding force of the ZrSiN-HA coating was the highest, and its anticorrosive performance was the strongest.

CONCLUSIONThe application of ZrSiN-HA coating is advantageous to the long-term retention of implant, and it has huge latent application value to dental dummy.
