Objective:To study the effect of OSAHS on adult nasal-cycle.Method:The nasal cycle of 20 healthy adults,18 patients of snoring and 22 patients of OSAHS were examined with acoustic rhinometry,which was performed every 30 minutes in 7 hours.Result:The ratio of nasal cycle in healthy adults was(19/20,95.0%), in snoring patients was(15/18,83.0%),in patients of OSAHS was(15/22,68.2%). The mean alteration amplitude of nasal cycle in healthy adults was significantly larger than that in patients with OSAHS (P<0.05).The distribution of the healthy adults and patients with OSAHS between the typical cycle categories was significantly different(P<0.05).Conclusion:The characteristics of nasal-cycle in of OSAHS patients were different with healthy adults,which maybe owing to change of physical function of nasal cavity.

Objective To clone and sequence the cysteine protease inhibitor gene of periodic Brugia malayi(BmCPI) and predict B-cell epitopes in amino acide sequence of BmCPI in order to provide basis for further study the expression of BmCPI and its function. Methods Total RNA was extracted from periodic Brugia malayi.A couple of specific primers were designed on the basis of known sequences of cysteine protease inhibitor gene from BmCPI. The desired gene was amplified by PCR technique from cDNA. The PCR products were purified and cloned into plasmid pGEM-T by T-A cloning method, transformed into Escherichia coli(E, coli) strain DH5α. The recombinant plasmids were screened and identified by digestion with restriction enzyme and PCR amplification. Five parameters and methods were used to predict B-cell epitopes in amino acide sequence of BmCPI. Results For RT-PCR, a specific band of around 621 bp was amplified. The same band was obtained by double restriction of recombinant plasmids or PCR using recombinant plasmid as template. The result of DNA sequencing showed that BmCPI shares 99% nucleotide sequence identity with that of published sequence. It showed that B-cell epitopes were probably at or adjacent to 23 - 32, 50 - 79 and 117 - 126 in its amino acide sequence. Conclusions pGEM-BmCPI is successfully constructed and sequenced, anticipated objective is reached and conditions is provided for further study of BmCPI expression and its function.

Objective To understand the distribution of infectious pathogens and antibiotics resistance from children patients with dacryocystitis .Methods Lacrimal secretion specimens of the outpatients with dacryocystitis were identified for bacteria using automatic instrument VITEK2 and API systems .Antibiotics sensitivity tests were detected by using VITEK 2 instrument and K‐B method .Results There were 800 strains of pathogenic bacteria isolated from eye secretions .Gram positive bacteria were 502 strains ,accounting for 62 .75% ,mainly of which were Streptococcus pneumoniae ,Streptococcus viridans and Staphylococcus au‐reus .Gram negative bacteria were 295 strains ,accounting for 36 .88% ,mainly of which were Klebsiella pneumoniae and Pseudo‐monas aeruginosa .There were 3 strains of Candida albicans ,accounting for 0 .37% .Streptococcus pneumonia and Streptococcus viridans were highly resistant to tobramycin ,erythromycin and clindamycin .At the same time ,Staphylococcus aureus resistant rate to penicillin was 99 .3% .The resistant rate of Klebsiella pneumoniae to ampicillin was 98 .6% ,but susceptible to the third generation cephalosporins and tobramycin ,and completely susceptible to imipenem .Most of children patients with dacryocystitis were from 1 month to 1 year old .Conclusion Children patients with dacryocystitis were mainly distributed in infants .Antibiotic resistant rate of pathogenic bacteria might be high .

ObjectiveTo analysis the clinical features of thoracic spine and spinal cord injury (SCI) and summarize the inclusive standard of cellular transplant clinical trial for SCI.MethodsThe data of 72 cases with thoracic spine and spinal cord injury from 1990 to 2005 were analyzed retrospectively.ResultsMean follow-up period was 20 months (6～48 months). There was no recovery in 12 spinal cord injury without radiographic abnormality (SCIWORA) patients, but improvement of urine function in 4 cases. 5 cases of 52 fracture-dislocation complete injury were improved to grade B (sense recovery), rate of recovery was 9.6%; recovery rate was 62.5% in incomplete injury. Sense recovery of all cases was better than motor recovery. Partial cases appeared spasm paralysis relief.ConclusionIncidence rate of complete injury is high and recovery is bad in thoracic spine and spinal cord injury. The inclusive standard of cellular transplant clinical trial for SCI is old complete thoracic spinal cord injury without residual compression.

Objective To investigate the distribution characteristics of methicillin-resistant Staphylococcus aureus (MRSA)in a children's hospital,and provide basis for the prevention and control of MRSA infection in children. Methods Children who admitted to a children's hospital from 2011 to 2015 were analyzed retrospectively,clinical data of children,isolation of pathogens,types of specimens,and healthcare-associated infection(HAI)status were analyzed.Results From 2011 to 2015,a total of 911 children isolated Staphylococcus aureus (SA,1108 positive specimens),494 of whom isolated MRSA (599 positive specimens),54.23% of children isolated MRSA(isolation rate of specimens was 54.06%);there was no significant difference in the isolation rate of MRSA between children of different genders(P > 0.05);isolation rate of MRSA in different age groups was statistically significant(P <0.05).Isolation rates of MRSA from blood,puncture fluid,secretion,and pus were 68.97%,66.00%,55.81%, and 54.47% respectively.Isolation rate of SA and MRSA increased from 0.61% and 21.74% in 2011 to 1.40%and 75.59% in 2015 respectively,difference were both significant(both P <0.05).Incidence of SA and MRSA in-creased from 0.198% in 2011 to 2.697% and 2.119% in 2015 respectively,both showed an upward trend year by year(both P <0.05).Conclusion Isolation rate of MRSA and incidence of HAI in this children's hospital increased year by year,it is necessary to intensify management,use antimicrobial agents scientifically and rationally,timelyperform disinfection and isolation,so as to curb the emergence and spread of MRSA in hospital settings.

Objective To investigate the efficacy and tolerability of a recombinant human tumor necrosis factor:Fc fusion protein (rhTNFR:Fc,with a trade name of Yisaipu) in the treatment of moderate to severe psoriasis vulgaris.Methods A multicentre,randomized,double blind,and parallel-controlled trial was performed.One hundred and forty-four patients with moderate to severe psoriasis vulgaris from four centres were randomly assigned and treated with either once-weekly subcutaneous injection of rhTNFR:Fc (50 mg) or oral methotrexate (MTX)(7.5 mg) for 12 weeks.Patients were followed up at 2,4,8,12 weeks after the treatment.Results One hundred and twenty-four patients finished the 12-week course of treat- ment.At 12 weeks after the treatment,a 50%,75%,90% improvement in psoriasis area and severity index (PASI) was achieved by 86.11%,76.39%,52.78% respectively of rhTNFR:Fc-treated patients,and by 63.89%,44.44%,22.22% respectively in MTX-treated patients,and all the three improvement rates were of significant difference between the two groups of patients (all P0.05).Conclusion Compared with MTX,rhTNFR:Fc acts more quickly with a higher cure rate and less toxic reactions in the treatment of psoriasis vulgaris.
