To identify the receptors for the outer membrane protein H (OmpH) of avian P.multocida,the membrane proteins of chicken embryo fibroblast (CEF) cells were separated by SDS-PAGE and analyzed by Ligand blot.The OmpH-binding protein was identified by MALDI-TOF mass spectrometry,and its distribution in the membrane proteins of different host esophageal mucosal cells was detected by Ligand blot,ELISA and immunofluorescence microscopy,respectively.Ligand blot analysis showed that a 49-kDa membrane protein of CEF cells bound to recombinant OmpH,and MALDI-TOF spectral results demonstrated that the OmpH-binding protein was ATP synthase β subunit.In addition,the OmpH receptor was present in the chicken and rabbit mucosal cell membranes,but was not detected in the bovine and swine mucosal cell membranes.The above results indicate that the OmpH receptor may be CEF cell-derived ATP synthase beta subunit.

Objective:To understand the medication safety events about cephalosporin in our hospital in order to provide evidence for the better medication safety of cephalosporin. Methods:Adverse drug reaction ( ADR) reports, medication error ( ME) reports and drug quality problem records about cephalosporin in our hospital were collected and the critical indicators in the reports were analyzed. Re-sults:The ADR reports selected in our hospital were mainly reported by pharmacists. More males were involved in the related patients, and young adults were in the majority. Second and third-generation cephalosporin were the major drugs used in the reports. The damages in skin and its appendages were the major damages in organs. The ME reports selected in our hospital were totally reported by pharma-cists. Errors in frequency and dose of drug administration were the most common, and the main causes were lack of knowledge and train-ing. No serious quality problem in cephalosporin was found in our hospital, and the inner and outer packaging in damaged conditions was the most common problems in our records. Conclusion:Cephalosporin as one widely used antibacterial agent is considered safe and effec-tive. Because of its large amount of application, cephalosporin should be paid more attention by health care professionals. MEs should be avoided as far as possible. ADRs should be treated timely and properly in order to decrease medical disputes. More attention should be paid to ensure security of drug use for patients.

OBJECTIVE: To assess the effect of disinfectant (Cavicide) with benzethon chloramine and isopropanol as main active ingredients disinfectant on dental impression accuracy. METHODS: The effect of Cavicide on three impression materials (alginate, polyether and vinylpolysiloxane) were assessed using a standard model. The standard model was digitized by an extraoral scanner (IScan D103i, Imetric). For each kind of impression materials, thirty impressions were taken following the manufactures' instruction in the same conditions. Subsequently, the impressions were randomly divided into three groups, with ten impressions in each group. After the impression taking was completed, the three groups underwent pure water rinse for 1 min (blank control, BC), 2% glutaraldehyde solution immersion disinfection for 30 min (glutaraldehyde, GD), and Cavicide solution spray disinfection for 5 min (Cavicide, CC), respectively. All the impressions were digitized by the extraoral scanner (IScan D103i, Imetric) after disinfection and exported to a dedicated three-dimensional analysis software (Geomagic Qualify 2014, Geomagic, USA). In the software, the digital models of the impressions were trimmed to teeth and then superimposed with the digitized standard model via best-fit alignment. Root mean square (RMS) was used to evaluate the deviations between the impression and the standard model. The deviation in the anterior and posterior regions was evaluated respectively. One-way ANOVA test and the LSD post-hoc test were used to compare the deviations between the three groups (P < 0.05). The color map of each superimposition was saved for visual analysis. RESULTS: For the polyether and vinylpolysiloxane materials, the difference between the three groups was not statistically significant (P=0.933, P=0.827). For the alginate material, the difference in posterior region between group GD and group BC, as well as group GD and group CC were statistically significant (GD vs. BC, P=0.001; GD vs. CC, P=0.002), while the difference between group BC and group CC was not statistically significant (P=0.854). The visual analysis showed an obvious deviation in the buccal-lingual direction in group GD. CONCLUSION Disinfectant (Cavicide) with benzethon chloramine and isopropanol as main active ingredients using spray disinfection has no effect on the accuracy of the alginate, polyether and vinylpolysiloxane impressions.

Objective To investigate the expression of VIT-1 gene in melanocytes of patients with vitiligo, and to analyze the difference of its sequence. Methods The skin from the foreskins of healthy men by circumcision and from the non-lesional area on the buttocks of 5 patients were digested by dispase, then the epidermis and dermis were separated, and the melanocytes were isolated. Then we cultured the melanocytes from the controls in TICVA medium and those from the patients in TICVA medium supplemented with basic fibroblast growth factor (bFGF) and endothelin-1 ( ET-1). The expression of VIT-1 gene was measured by RT-PCR, the full-length cDNA of VIT-1 ORF was cloned and sequenced, and sequence difference was analyzed by CLUSTAL W ( 1.83 ) software. Results The expression levels of VIT-1 gene were significantly lower in melanocytes from the patients than in those from the controls. An 81 bp-intron was found in the VIT-1 ORF. VIT-1 was a fragment of FBXO11, located at its 3' end. Conclusion VIT-1 gene is not a new gene, but a fragment of FBXO11, and a member of F-box protein family.
