Objective Streptococcus pneumoniae can form biofilms .The aim of this study was to investigate the biofilm forma-tion of Streptococcus pneumoniae and the relationship with antibiotic resistance of penicillin etc . Methods A total of 147 clinical iso-lates of Streptococcus pneumoniae were collected from 7 teaching hospitals in Nanjing from 2010 to 2012.Minimal inhibitory concentration (MIC) of penicillin, erythromycin, cefuroxime and ceftriaxone were determined by agar dilution method .Streptococcus pneumoniae with various penicillin MIC was selected randomly as follow:MIC≤0.065μg/mL, 0.5μg/mL, 2μg/mL and≥4μg/mL, which was incuba-ted to form biofilms in 96-well plates and 24-well plates for 24 hours.The A values at 570 nm was measured and the biofilm was observed through confocal laser scanning microscope ( CLSM) . Results The biofilm semi-quantitative detection and CLSM both displayed that all strains formed biofilms.The A value of the group which penicillin MIC was ≤0.065μg/mL (0.228 ±0.063) was higher than the 0.5μg/mL group (0.200 ±0.061) and the≥4μg/mL group (0.186 ±0.050) (P<0.05) , and there was no difference among the groups which penicillin MIC were 0.5μg/mL, 2μg/mL and≥4μg/mL, respectively (P>0.05).The A value of the group which erythromycin MIC was ≤0.5μg/mL (0.211 ±0.068) was higher than the ≥4μg/mL group (0.201 ±0.052) (P>0.05).The A value of the group sensitive to cefuroxime (0.216 ±0.062) was higher than the group resistant to cefuroxime (0.196 ±0.054) (P<0.05). Conclusion Streptococcus pneumoniae can form biofilms .Streptococcus pneumoniae with high antibiotics MIC has a trend of weakened biofilm formation .

Objective To analyze and compare the clinical application values of procalcitonin (PCT),leukocyte count (WBC) and C-reactive protein(CRP) in elder patients with infection.Methods In patients(age≥ 65 yrs,axillary temperature ＞38.0℃)with infection or suspected infection,PCT,WBC,CRP and other bacteriological examination were performed.The electronic medical records from the HIS system of our hospital were analyzed retrospectively in combination with medical history.Results Of the enrolled 219 patients,65 ones were in control group,48 ones SIRS,51 ones sepsis and 55 ones MODS.There was a positive correlation between the level of serum PCT and the infection degree.The Spearman correlation coefficient was 0.706 (95％CI:0.616-0.797,P=0.000).Based on the highest Youden index (sensitivity+specificity-1),the best cutoff point of diagnosis for PCT was ＞0.341 μg/L (sensitivity 84.5％,specificity 55.8％),a analysis of receiver operating characteristic(ROC) curve about PCT,WBC and CRP was carried.Area under the curve (AUC) of PCT to controlled infection was 0.916 (95％CI:0.864-0.967,P=0.000).Based on the highest Youden index (sensitivity+ specificity-1),the judging threshold of PCT to infection controlled or not was 0.73 μg/L (sensitivity 84.6％,specificity 88.0％).PCT level after treatment ＞0.73 μg/L showed the uncontrolled infection,＜ 0.73 μg/L controlled.Conclusions PCT has a higher specificity for elder patients with infection.The variation of PCT level can guide the application of antibiotics,avoid abuse and decrease the occurrence of drug-resistant bacteria.

Based on the transcriptome database of Salvia miltiorrhiza, specific primers were designed to clone a full-length cDNA of ent-kaurene oxidase synthase (SmKOL) using the RACE strategy. ORF Finder was used to find the open reading frame of SmKOL cDNA, and ClustalW has been performed to analysis the multiple amino acid sequence alignment. Phylogenetic tree has been constructed using MEGA 5.1. The transcription level of SmKOL from the hairy roots induced by elicitor methyl jasmonate (MeJA) was qualifiedby real-time quantitative PCR. The full length of SmKOL cDNA was of 1 884 bp nucleotides encoding 519 amino acids. The molecular weight of the SmKOL protein was about 58.88 kDa with isoelectric point (pI) of 7.62. Results of real-time quantitative PCR analyses indicated that the level of SmKOL mRNA expression in hairy roots was increased by elicitor oMeJA, and reached maximum in 36 h. The full-length cDNA of SmKOL was cloned from S. miltiorrhiza hairy root, which provides a target gene for further studies of its function, gibberellin biosynthesis and regulation of secondary metabolites.

To study the correlation between acute lymphoblastic leukemia (ALL) and HLA-A, B and DRB1 gene in southern Chinese Han population and to investigate the susceptible HLA gene to ALL, a total of 4707 healthy volunteer bone marrow donors from southern Chinese Han population were used as a control group, 201 patients diagnosed as patient group from southern Han individuals were genotyped at HLA-A, B and DRB1 loci by PCR-SSP, PCR-SSOP and SBT. HLA allele frequency and its distribution of ALL patient group were compared with the control group by using chi(2) test, and calculated the statistic value of relative risk (RR), pathogenicity score (EF) and preventive score (PF). The results showed that in comparison with the control group, the gene frequence of HLA-A26, B56 and DR9 increased significantly, but the gene frequence of HLA-A30, A33 and B58 allele frequency decreased significantly for patients with ALL. It is concluded that HLA-A26, B56 and DR9 gene have a high correlation with ALL and seem to contribute the genetic susceptibility to ALL in southern Chinese Han populations. However, HLA-A30, A33 and B58 gene seem to have protective role for southern Han individuals suffered from ALL.

OBJECTIVETo evaluate the Chinese language version of the appraisal questionnaire (AQ) for HIV/AIDS (HIV positive persons).

METHODSThe scale was translated and adapted into Chinese and then reversely translated into English. The internal consistency reliability, structural validity, differential validity and predictive validity were evaluated by prevalence study in the city of Guangzhou.

RESULTSCronbach's alpha coefficient achieved a value ranged from 0.530 to 0.886, with satisfied predicted validity. The regression equation accounted for 24.4% of variance in anxiety, and all factors of cognition accounted for 11.4% of variance, among all factors, only factor one had significant influence on anxiety (t=3.838, P<0.001); the regression equation accounted for 38.6% of variance in depression, and all factors of cognition accounted for 26.0% of variance. Factor I and factor II had significant influence on depression (t=5.707, P<0.001; t = -2.876, P<0.01). The results of differential validity suggested the mean scores of factor III were lower in the group with lower education level and monthly salary. Meanwhile, the persons with monthly salary under 300 yuan RMB had higher mean score of factor I, and the persons with lower academic degree had lower mean score of factor II. The principal-components factor analysis yielded three factors with common factor larger than 1.0, which were threat, challenge and controllability; and the three factors accounted for 62.23% of the total variance.

CONCLUSIONThe AQ Chinese version attained satisfactory reliability and validity. Even considering some essential explanatory words for the Chinese version, the scale might be attempted to use in the population with HIV in our country.
