Objective To compare the sensitivity and specificity of dot immunogold method (DIM) and particle agglutination (PA) for the diagnosis of mycoplasma pneumoniae (MP) infection. Methods The 190 serum specimens of 113 children with mycoplasmal pneumonia (infection group) and 50 serum specimens of 50 health children (health group) were tested for MP by PA and DIM- A and B. Results In infection group, the positive rates of DIM- A and B were 82.63% (157/190) and 84.74%(161/190), and there was no statistical difference (χ2 = 0.31, P>0.05); the positive rate of PA (titer ≥1:160) was 70.00%(133/190), the positive rate of PA was significantly lower than that in DIM-A and B, and there were statistical differences (P<0.05). In infection group, with the increase of PA titer, the positive rate of DIM was gradually increased, and there was a correlation between 2 methods (rA=0.972, rB=0.830);the positive rates of DIM- A and B in serum specimens of PA negative were 40.62%(13/32) and 53.12%(17/32), and in the PA titer of 1:5120, there was still a negative result in DIM. In health group, the positive rates of DIM-A and B were 26.00% (13/50) and 28.00% (14/50), and there was no statistical difference (χ2 = 0.66, P>0.05); the positive of PA was 8.00% (4/50), the positive rate of PA was significantly lower than that in DIM- A and B, and there were statistical differences (P<0.05 or<0.01). Conclusions Compared with the PA, DIM has low sensitivity and poor specificity for clinical diagnosis. DIM is not suitable for clinical diagnosis of MP infection.

[Summary] A total of 128 individuals with type 2 diabetes underwent continuous glucose monitoring for 3 consecutive days.The dawn phenomenon was defined by three different parameters according to the previous research:(1)the absolute increase of glucose level from nocturnal nadir to prebreakfast value(?G) above 20 mg/dl;(2)?G above 10 mg/dl;( 3 ) insulin requirement increased at least 20%.The participants were secondarily separated by presence/absence of a dawn phenomenon based on the definitions above.The impact on blood glucose fluctuation of different groups was assessed according to the standard deviation of blood glucose( SDBG) , the area under curve above 10 mmol/L ( AUC ) , and the mean amplitude of glycemic excursions ( MAGE ) , etc.The frequencies of dawn phenomenon were 64.8%(?G≥20mg/dl), 85.2%(?G≥10 mg/dl), and 59.4%(rise in insulin requirement≥20%)respectively.The impacts on SDBG, AUC, MAGE, and MODD were without statistical difference(P>0.05) between the presence and absence of the dawn phenomenon patients when?G≥10 mg/dl.However, the differences reached statistical significance(P<0.05) when ?G≥20 mg/dl and the increase in insulin requirement≥20%. Besides, the incidence of dawn phenomenon was positively correlated with HOMA-IR, HbA1C , and free C-peptide.Dawn phenomenon is a very frequent event in type 2 diabetes and not only impacts the overall glycemic control but also exaggerates glucose fluctuation.To be clinically relevant, ?G≥20mg/dl should be taken as the quantitative criterion of the dawn phenomenon.

OBJECTIVE To investigate in vitro activities of 12 antimicrobial agents including cefmetazole against extended-spectrum beta-lactamases-producing Escherichia coli(528 strains),Klebsiella pneumoniae(311 strains) and Proteus mirabilis(15 strains).METHODS They all collected from 15 teaching hospitals in China during 2005 and 2006 and included in the study.The levels of minimal inhibitory concentration(MIC) of 12 antimicrobial agents were determined by agar dilution method.WHONET 5.4 Software was used to analyze the data.RESULTS Against ESBLs-producing E.coli and ESBLs-producing K.pneumoniae,carbapenems were the most active antimicrobial agents(all 100.0% susceptible),followed by cephamycins(80.1-97.3%).Piperacillin/tazobactam(78.5-95.1%)showed a higher activity than cefoperazone/sulbactam(44.1-56.2%).The susceptible rate to ceftazidime against ESBLs-producing E.coli was remarkably higher than the other three cephalosporins,however the differences did not happen to ESBL-producing K.pneumoniae obviously.The susceptible rate to cefuroxime was below 1.6%.ESBLs-producing K.pneumoniae showed high sensitivity to carbapenems,cephamycins and ?-lactam/lactamase inhibitor combinations(all 100% susceptible),however the susceptible rates to cephalosporins were relatively lower.CONCLUSIONS Carbapenems and cephamycins remain the relatively high activity against ESBLs-producing Enterobacteriaceae.
