Hepcidin are small cationic peptides with antibacterial activity expressed mainly in the liver of living organisms, and they play important roles in the host's immune response against microbial invasion and regulation of iron metabolism. Thus, they are considered to be good substitutes for traditional antibiotics. It is a good choice that the antimicrobial peptides are prepared by recombinant DNA expression. In the present study, two hepcidin mature peptide cDNAs from channel catfish (Ictalurus punctatus) (mCH) and tilapia (Oreochromis niloticus) (mTH) were connected by SOE-PCR in order to obtain more recombinant hepcidin with broad antimicrobial spectrum, and EcoR I and Not I sites were added to 5'- and 3'- ends of the fragment, respectively. The recombinant eukaryotic expression vector "pPIC9K-mCH-mTH" was successfully constructed, and transformed into Pichia pastoris GS115. The transformants containing multicopy gene insertion were selected by using different concentrations of G418 and other specific mediums, and identified by PCR for yeast genomic DNA. Expression was induced by adding 1% methanol at 30 degrees C for different times. Tricine-SDS-PAGE analysis demonstrated that the most appropriate expression time was 72 h, at which a high expression yield (77 mg/L) for the target protein was exhibited. The highly purified target protein was obtained from the fermentation supernatant by SP-Sepharose cation exchange chromatography. Bacteriostatic activity assay demonstrated that the fermentation supernatant containing the target protein and purified recombinant target protein had bacteriostatic activities against gram-positive and gram-negative bacterium. The present result provides the important initial value for industrial production of hepcidin antimicrobial peptide.

Objective To investigate the characteristic changes of the metabolism products in the auditory cortex (transverse temporal gyrus)in patients with metabolic syndrome combined with sensorineural deafness using 1 H magnetic resonance spectroscopy (1 H-MRS),and to find out the early warning indicators of sensorineural deafness in patients with metabolic syndrome.Methods The pure tone audiometry (PTA)was performed in 142 pa-tients with metabolic syndrome (diagnosed by endocrinology department),and 15 healthy subjects as the control group.The patients were divided into four groups:the metabolic syndrome group;the metabolic syndrome group with unilateral,the bilateral deafness group,and the control group.Cerebral metabolism was studied by assessing the ratios of nitro-acetyl aspartate contrast to choline (NAA/Cho)as well as to creatine (NAA/Cr),myo-inosi-tol to creatine (mI/Cr)and choline to creatine (Cho/Cr)ratios in the auditory cortical separately in these groups. ROC curves were made for those metabolism markers to find the best diagnostic threshold.Results Significantly lower values of NAA/Cho ratio and higher values of Cho/Cr were observed in metabolic syndrome in the control group (P<0.05),Cho/Cr higher than those (P<0.05).NAA/Cho ratios in the injured and uninjured auditory cortex of MS with unilateral deafness were significantly lower than those in the control group (P<0.05).A self-comparison was made between the inj ured and uninj ured auditory cortex,the result showed that NAA/Cho ratio had significant differences.All of the metabolisms were tested by the curve of ROC.The area of NAA/Cho under the ROC curve was 81%,which had a higher accuracy.NAA/Cho equating to 1 .82 could be used as the boundary indi-cators between metabolic syndrome without deafness and with deafness groups.The areas of the other indicators un-der the ROC curve were <50%.Conclusion NAA/Cho may be the early warning marker of sensorineural deafness in patients with metabolic syndrome.

BACKGROUND: Bone marrow mesenchymal stem cells (BMSCs) can be induced to differentiate into neuron-like cells in new environment after transplantation, and then to replace damaged cells for reconstructing neural circuit. OBJECTIVE: To establish the co-culture system between rat BMSCs and neural cells in vitro, and to study the influence of neural cells on the differentiation of BMSCs into neuron-like cells in the co-culture system. METHODS: The neural cells obtained from Wistar rat fetal brain tissue and BMSCs gained from rat thighbone were co-cultured in Transwell culture plate. The morphological changes of BMSCs were observed and the special markers of neural cells in BMSCs were examined by immunofluorescence on the fifth day of the co-culture. The results were compared with control group which where BMSCs were alone cultured. RESULTS AND CONCLUSION: BMSCs in the neural cells co-culture system extended, were radial, connected each other. Neuron specific enolase immunoreactions showed positive results, showing neuron-like cells. The positive ratio of neuron specific enolase-positive cells was (33.0±10.5)%. However, BMSCs in the control group did not express neuron morphological character. Immunofluorescence exhibited that cells were negative for neuron specific enolase. These indicate that microenvironment provided by neurons improves the differentiation of BMSCs into neuron-like cells.

To explore effects of homologous sclera implantation for treating eyelid cicatricial entropion after burns.Fifteen patients (15 eyes) with cicatricial entropion after burns were operated under microscope with homologous sclera graft in the eyelid.The tarsus was separated fully from the palpebral margin of the musculus orbicularis oculi,with deleted area of the conjunctiva for implantation,and homologous sclera graft was taken on the implant bed and sutured together.The implant and the bed were well cured together during postoperative follow-up,with less than 10 percent of constriction of the implant,indicating obvious effect of homologous sclera graft for treating the eyelid cicatricial entropion after burns.

OBJECTIVE:To provide reference for the rational clinical prophylactic use of antibiotics. METHODS:The cases in whom the clinical prophylactic use of antibiotics between 2006 and 2007 in our hospital showed failure in efficacy were monitored to analyze the cause of failure,meanwhile the clinical samples were sent for culture,isolation,identification and drug susceptibility tests as well as drug resistance analysis. RESULTS:Cephalosporins,Quinolones,Penicillins,Cefhalosporins + enzyme inhibitor were more commonly used antibiotics in our hospital,with drug resistance rates at 57.21%,65.14%,68.63%,and 18.81% respectively. Among the total 240 cases monitored,the prophylactic use of antibiotics totaled 877 times,of which,388 (44.24%) were non-indicated drug use,459 (52.34%) showed drug resistance,286 (32.61%) involved improper drug choice,and 42 (17.50%) showed dual infection. CONCLUSION:The clinical prophylactic use of antibiotics in our hospital is far from perfect; therefore,it is urgent to tighten control on the standard prophylactic use of antibiotics.
