Background Posterior capsular opacification (PCO) is a primary cause of blurred vision after extra-capsular cataract extraction (ECCE),and there is a higher incidence of PCO in the patients with diabetes mellitus.Echistatin (Ecs) can suppress the proliferation of lens epithelial cells (LECs) and thereby inhibit the formation of PCO.However,its mechanism and safe dose deserve to study.Objective The aim of this study was to observe the inhibitory effect of different concentrations of Ecs on LECs proliferation in the early stage of PCO in diabetic rabbits and explore the safe dose of Ecs.Methods Diabetic mellitus was induced by injection of 90 mg/kg alloxan via ear vein in 15 New Zealand white rabbis.ECCE was performed in the right eyes of the rabbits.The rabbits were randomized to the control group and 5.0,7.5,10.0 and 15.0 μg/ml Ecs group according to randomized number table method.Ecs of 0.2 ml in above doses was injected into the anterior chamber after ECCE in different concentrations of Ecs groups,and 0.2 ml distilled water was used in the same way in the only diabetic rabbits as the control group.Postopeartive response of ocular anterior segment was observed and PCO was graded under the slit lamp microscope.The corneal and retinal specimens were prepared 10 days after operation for the assay of preliferative cell nuclear antigen (PCNA) expression in LECs by immunochemistry to evaluate the effective dose of Ecs.Regular histopathological examination was performed,and apoptosis of corneal endothelial cells and retinal cells was detected by TUNEL method to assess the safe concentration of Ecs.Results Different degrees of corneal edema and exudation in anterior chamber were seen in the eyes of different groups.The inflammatory response disappeared 3-5 days in the control group and 5.0 μg/ml Ecs group and 7 days in the ≥7.5 μg/ml Ecs groups.PCO was 1-2 grade in the control group and 5.0 μg/ml Ecs group and 0 grade in the ≥ 7.5 μg/ml Ecs groups.The difference in the positive expression level (absorbance,A) for PCNA in LECs was significantly different among the control group and various Ecs groups (F=18.006,P=0.001),and the positive expression level of PCNA in the ≥ 7.5 μg/ml Ecs groups was markedly reduced in comparison with that in the control group (P =0.010,0.001).Hematoxylin and eosin staining showed an normal morphology and order arrangement in corneal endothelial cells and intact structure in retinal internal limiting membrane in the groups.TUNEL assay revealed that the apoptosis values (mean A value) of corneal endothelial ceils and retinal cells in the ≤ 10.0 μg/ml Ecs groups were not significantly changed in comparison with the control group (all at P＞0.05),but the apoptosis values in the 15.0 μg/ml Ecs group were markedly higher than those in the control group (P=0.004,0.018).Conclusions Ecs can inhibit the early PCO in diabetic rabbits and show the optimal effect at the concentrations of 7.5 and 10.0 μg/ml without visible eytotoxicity to eye other tissues.Therefore,these two doses of Ees might be used for the study of long-term therapeutic effectiveness.

OBJECTIVE:To investigate the distribution of common bacterial pathogens and their drug resistance in our hospi-tal,and to provide guidance for clinical treatment and promote rational drug use. METHODS:The results of microorganism cul-ture,isolation and identification,and drug sensitivity test were collected from our hospital during Aug. 2010-Sept. 2014. The isolat-ed pathogens and drug sensitivity were analyzed statistically. RESULTS:14 687 strains of bacterial pathogens were isolated or cul-tured in 4 years,among which 1 790 strains of Pseudomonas aeruginosas were most common Gram-negative bacterium,followed by 1 313 strains of Escherichia coli and 770 strains of Klebsiella pneumoniae,670 strains of Bauman acinetobacter;915 strains of Staphylococcus aureus were most common Gram-positive bacterium,followed by 223 strains of Enterococcus faecalis,98 strains of Staphylococcus haemolyticus;1 446 strains of Mycoplasma urealytium were the most common microorganism,followed by 769 strains of Candida albicans,187 strain of Mycoplasma hominis. CONCLUSIONS:Regular detection of bacteria distribution and bacterial resistance monitoring are conducive to understand the bacterial resistance of the medical institutions so as to provide guid-ance for clinical treatment and promote reasonable application of antibacterial drugs.

Objective To investigate molecular typing and drug resistance patterns of 98 Klebsiella pneumoniae (K.pneumoniae) isolated from type 2 diabetes patients complicated with maxillofacial infection,to research the virulence and resistance mechanisms.Methods The study was a prospective study that adopted the method of continuous sampling from fixed location,from March 2010 to October 2012.The maxillofacial surgery patients diagnosed with type 2 diabetes complicated with maxillofacial infection were chosen in 7 hospitals in Zhengzhou as the research object,and a total of 431 pus sample were collected continuously,in which 98 strains K.pneumoniae were isolated and identified.The Kirby-Bauer disk diffusion test was conducted in 98 strains to determine the resistance to 19 antibacterial agents.K.pneumoniae chromosomal DNA were digested by restriction endonuclease Xba Ⅰ and analyzed by pulsed-field gel electrophoresis (PFGE).PFGE patterns of K.pneumoniae strains were analyzed using Fingerprinting software.The relationship between the molecular types and resistance phenotype was observed.The extended spectrum β-1actamase-producing K.pneumoniae were screened out by the double disc synergy test (DDST)Polymerase chain reaction (PCR) was used to detect resistant genotypes,serotype and virulence genes.The purified PCR products of resistant genes were cloned and sequenced.Hypermucoviscosity phenotype of all strains were determined by string test.Results Much severer drug-resistance for K.pneumoniae was identified and the result of extended-spectrum beta-lactamase producing rate was 57.1 ％.Ninety-eight strains were dispatched into 13 groups by PFGE.No dominant bands and specific extended-spectrum beta-lactamase DNA bands were found.The results of PCR showed that among the 56 strains of extended spectrum β-lactamase-producing K.pneumoniae,40 were positive for blaSHV (accounting for 71.4％),28 positive for blaTEM (accounting for 50.5％),21 positive for blaCTX-M (accounting tor 37.5％).The sequencing results were as follows:TEM-1,CTX-M-3 and a variety of SHV.Serotype K1,K2,K3,K5,K20,K54 and K57 and 3 kinds of virulence genes were detected,but not in strong toxicity-based.Hypermucoviscosity positive rate was 31.6％ (31/98).Conclusion Much severer drug resistance of K.pneumoniae in this study was identified and resistant mechanism was complex,in which strong toxicity serotype and virulence geues exist,which need more attention from clinical.

OBJECTIVE: To observe the repairing effects of bone marrow transplantation with nerve tissue committed stem cell (NTCSCs) on experimental rats with injury of noise-induced hearing loss. METHOD: Guinea pigs were randomly divided into control group, noise exposure group and the transplanting group. A week after white noise exposure of 110 dB, NTCSCs and PBS were injected into guinea pigs of the noise exposure group and the transplanting group respectively. One week after noise exposure to four weeks continuous administration. ABR thresholds were measured respectively prior to the experiment, 1 week post-noise,1, 2 and 4 weeks post-drugs, The changes of cochlea hair cells were also observed by a scan electron microscope (SEM). RESULT: The ABR threshold shifts in the transplanting group were significantly fewer than that in the noise exposure group. SEM showed that hear hair of the inner and outer hair cells in noise exposure group displayed mess, fusion and imperfections. In the transplanting treatment group, the hair cells displayed slight pathological changes, there wasn't significant differents comparied with normal group. The number of OHCs were relatively stable in the normal group, while the obvious OHC loss was observed in other groups. There was significant difference among the three groups, however, the OHC loss in the transplanting group was no significantly different to that in the noise exposure (P > 0.05). CONCLUSION The bone marrow NTCSCs which had been transplanted to rat cochlea could reduce the damage of the noise on the hair cell, and thus played a role in repairing the damage of auditory nerve.
