OBJECTIVE To investigate urogenital mycoplasma infection and its drug sensitivity in Beijing from Jul 2002 to Jun 2005. METHODS Mycoplasma were isolated and their antibiotic susceptibility was detected with Mycoplasma IST 2 Reagent Box from France. RESULTS Among 1806 cases 673 cases were with positive mycoplasma,accounting for 37.3% of the total.From them,Ureaplasma urealyticum(Uu) was positive in 541 cases(80.4%),higher than Uu combined with Mycoplasma hominis(Mh) infection(107 cases,15.9%) or Mh alone infection(25 cases,3.7%).The result of drug sensitivity test showed that Uu,Mh and Uu+Mh isolated from both sexes had different drug resistance.The most sensitive and stable antibiotics were josamycin(the rate of sensitivity was 98.7%) and pristinamycin(the rate of sensitivity 92.6%),the next was doxycyline(the rate of sensitivity was 91.8%).It seemed increasing sensitivity trend for tetracycline and erythromycin.The lowest rate of sensitivity was to ofloxacin and ciprofloxacin. CONCLUSIONS It is important to enhance the detection of drug resistance of mycoplasma,guide the drug use and prevent from producing antibiotic resistance.If antibiotic susceptibility testing of mycoplasma can not be tested,josamycin may be selected as the first choice to treat mycoplasma infection.

AIM:To investigate ischemia reperfusion (I/R)-induced proteomic changes in rat skeletal muscle. METHODS: Healthy male Wistar rats were randomly divided into two groups as follows (n=6): sham group and I/R group. I/R of right hind limb was induced by 4 h ischemia followed by 24 h reperfusion. The 2-DE was applied to separate the proteins extracted from skeletal muscle tissue at the end of experiment, followed by Coomassie Brillant blue R-250 staining. Computer image analysis was used to determine the differential expression of proteins between the two groups, and 7 protein spots expressed differentially were picked out and subjected to in-gel digest and MALDI-TOP for identification. RESULTS: 354?13 proteins were detected and the match rate was (78.7?1.4)%. 10 proteins displayed significant changes after I/R, of which, 6 proteins increased and 3 proteins decreased in expression. Moreover, 2 spots in I/R group were observed, only 1 spots of which in control. 5 proteins were identified after mass spectrometry. Mitochondrial aldehyde dehydrogenase (ALDH) precursor, heat shock 27 kD protein (HSP27), an unnamed protein product (increased in I/R group), ?-actin (decreased in I/R group), and nuclear transport factor 2 (NTF-2) W7a mutant were found in I/R group. CONCLUSION: I/R injury induced differential proteomic changes in rat skeletal muscle. ALDH, ?-actin and HSP27 expression, and NTF-2 mutation are involved in I/R injury.

Objective:To assess the genetic relationship of clinical isolates of carbapenem-resistant A.baumannii (resistant to both imipenem and meropenem) from January 2007 to March 2008 in Peking University Third Hospital for measures to decrease the isolates; to investigate the characteristics of patients with carbapenem-resistant A. baumannii colonization or infection and to evaluate antibiotic treatment for health care-associated infections caused by carbapenem-resistant A. baumannii. Methods: The medical records of patients with carbapenem-resistant A. baumannii colonization or infection were reviewed. Antibiotic susceptibilities of the isolates were determined by the standardized disk-diffusion method and the clonal relationship of the isolates was analyzed by pulsed-field gel electrophoresis. Results: A total of 49 carbapenem-resistant A. baumannii strains were isolated from the 49 patients hospitalized during the study period and pulsed-field gel electrophoresis typing yielded 7 different patterns. A total of 45 (91.8%)genotyped strains showed clonal relationship. The most frequently identified predisposing factors were intensive care unit stay, invasive procedures, and hypoalbuminemia. Chronic obstructive pulmonary disease (12 cases) and cerebrovascular disease (10 cases) were the most common comorbid conditions.The mortality of patients with carbapenem-resistant A. baumannii infection was 38. 1% (8 of 21 patients), and the acute physiology and chronic health evaluation Ⅱ score, initial antibiotic therapy failure rate and the presence of hypoalbuminemia were significantly increased in the death group. Combination therapy regimens had higher success rates than monotherapy regimens (11/13, 84. 6% vs. 3/17,17.6%). Conclusion: There has been clonal spread of carbapenem-resistant A. baumannii strains among patients in our hospital since 2007. Intensive care unit stay, invasive procedures, hypoalbuminemia, chronic obstructive pulmonary disease and cerebrovascular disease were common in patients with carbapenem-resistant A. baumannii colonization or infection. Antibiotic combination therapy may be effective for carbapenem-resistant A. baumannii infection.

Objective To explore the significance of FSH1 in the pathogenicity of M. canis. Methods Thirty M. cam's strains from tinea capitis lesions and 30 M. canis strains from tinea corporis lesions were cultured, passaged, and induced by medium containing skin tissue of scalp or foreskin from children. Semi-quantitative reverse transcription (RT)-PCR was carried out to detect the expression of FSH1 mRNA in the firstand fifth-generation M. canis strains, as well as M. canis strains induced by the skin tissues. Results The mRNA expression of FSH1 was higher in M. canis strains derived from tinea capitis lesions than in those from tinea corporis lesions (P < 0.01), but there was no significant difference between the first-generation and fifthgeneration M. canis strains (P> 0.05). The skin tissue from scalp and foreskin induced a significant elevation in the mRNA expression of FSH1 in these M. canis strains (F = 2025.713, 1833.139, both P< 0.01), and the inductive effect of the scalp tissue was different from that of the foreskin tissue (P < 0.01). Conclusions The FSH1 mRNA expression is different in M. canis isolated from different body sites. Local skin tissue has an inductive effect on the expression of FSH1 mRNA, and the inductive effect of scalp tissue is more apparent than that of foreskin tissue.

Objective To investigate the roles of hemopoietic stem cells (HSCs) in the pathogenesis of psoriasis. Methods HSCs were isolated from the bone marrow of a patient with psoriasis vulgaris and a normal human control. Forward- and reverse-subtracted cDNA libraries were constructed by using suppression subtractive hybridization (SSH) technique between HSCs from the patient and control. Bacterial PCR and dot hybridization were performed to screen for positive clones followed by gene sequencing, identification and functional analysis. Real time quantitative PCR was carried out to measure the mRNA expression of interferon-γ and thymosin 10 (TMSB10). Results Nine genes were screened from the forward-subtracted cDNA library which encoded interferon-γ, tyrosine phosphatase, SUMO1 activase, etc, and 8 genes including the TMSB10-encoding gene were screened from the reverse-subtracted cDNA library. The relative expression level of interferon-γ in HSCs from the patient was 47.5 times that in HSCs from the control, while the level of TMSB10 from the control was 22.6 times that from the patient. Conclusion The abnormal expression of 17 genes which encode interferon-γ, thyrosin, and so on, may be involved in the development of psoriasis.
