Objective To understand the prevalence,drug resistance and clinical features of children with acute lower respiratory tract infection(ALRI) caused by escherichia coli.Methods From Oct. 2005 to Oct. 2006,659 patients with ALRI who were admitted to hospital were chosen and their nasopharyngeal secretions were obtained and cultured.K-B disc diffusion for antibiotic susceptibility were performed for these clinical isolates.Results Among 659 patients,118 cases were isolated escherichia coli,the rate was 17.99% which had 90 boys and 28 girls.Eighty-seven of 118 E.coli strains were with extended-spectrum ?-lactamase(ESBLs),the rate was 73.73%.All of strains were sensitive to imipenem.For ESBLs-producing strains,the ratio of resistance tocefotaxime,ceftriaxone,cefuroxime,ampicillin,piperacillin were 78.81%,73.73%,73.73%,76.27%,78.81%,respectively.Conclusions The positive rate of ESBLs producing E coli in Kunming area is high and drug resistance is severe gradually.Imipenem can be the first selection for treatment on these infections.

Objective To investigate the antibiotic resistance of Acinetobacter baumannii,and to identify the risk factors for fatality of Acinetobacter baumannii bloodstream infection.Methods A retrospective review was conducted on 80 patients with Acinetobacter baumannii bloodstream infections admitted in Tianjin General Hospital during January 2011 to May 2014.Clinical data including demographic information,the ward of stay,underlying diseases,treatment,invasive procedures,antibiotic resistance,acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score at admission were collected.Multivariate Logistic regression analysis was performed to identify the risk factors for fatality.Results There were ≥90％ strains resistant to ceftazidime,ceftriaxone and cefoxitin,and 66.3％ strains were resistant to imipenem.While most strains were sensitive to cefoperazone/shubatan and tigecycline,and the resistance rates were 7.5％ and 2.5％,respectively.ICU admission (OR =6.67,95％ CI:2.01-22.07,P ＜0.01),multi-drug resistance (OR =3.55,95％ CI:1.30-9.69,P ＜ 0.05),APACHE Ⅱ score ≥ 19 (OR =39.00,95％ CI:9.87-154.09,P ＜ 0.01),artery catheterization (OR =3.24,95％ CI:1.16-9.04,P ＜ 0.05),central venous catheterization (OR =3.33,95％ CI:1.22-9.12,P ＜ 0.05),tracheal catheterization (OR=3.60,95％CI:1.31-9.88,P＜0.05),tracheostomy (OR=3.21,95％CI:1.19-8.66,P＜0.05),and other invasive procedures (OR =3.00,95％ CI:1.11-8.08,P ＜ 0.05) were the risk factors for fatality.Conclusion Invasive procedures and multi-drug resistance are associated with increased fatality of patients with Acinetobacter baumannii bloodstream infection.

DNA barcoding is a technique in which species identification and discovery are performed by using short and standard fragments of DNA sequences. In this study, eleven species of Paris, including seven varieties, were sampled. Five chloroplast sequences, psbA-trnH, rpoB, rpoC1, rbcL, matK, and one nuclear marker, the second internal transcribed spacer (ITS2) of ribosomal DNA, were amplified and sequenced. The PCR amplification and sequencing efficiency, intra- and inter-specific divergence and barcoding gap were used to evaluate different loci, and the identification efficiency was assessed using BLAST1 and Nearest Distance methods. The ITS2 sequences in the studied samples of Paris were amplified and sequenced successfully using primers designed by our group, while matK showed low level in the amplification and psbA-trnH was difficult for sequencing because of over 800 bp and poly (A) structure. Analysis of the intra- and inter-specific divergence and barcoding gap showed ITS2 was superior to other loci. The ITS2 showed a much higher percentage of success (100%) in identification than other five loci, none of which indicated more than 50% except matK (52.9%). The 2-locus combination of rbcL+matK didn't improve ability of authentication. In addition, the rate of successful identification with ITS2 kept 100% when the samples were expanded to 67 samples of 29 species. In conclusion, ITS2 can be used to correctly identify medicinal plants of Paris, and it will be a potential DNA barcode for identifying medicinal plants of other taxa.

A growing number of studies show that drug and non-drug means can be activated phosphatidyl inositol-3-kinase serine/threonine kinase(PI3K/Akt signaling pathway)in the beginning of reperfusion, and make its downstream fork protein transcription factor O3a (FoxO3a) phosphorylation, and then promote cell survival and reduce the apoptosis so as to alleviate the symptoms of myocardial ischemia.In this paper,the role of PI3K/Akt and FoxO3a effector in myocardial ischemia was reviewed, and illustrated the role of PI3K/Akt/FoxO3a signaling pathway in myocardial ischemia.

HLA-Cw belongs to classic HLA-I gene, HLA-Cw molecules have high polymorphism like HLA-A and B molecules. They distribute extensively on the surfaces of karyote, not only presenting endogenetic antigen to CD8+ T cells to induce specific killing effect, but also participating in immunologic reaction as the ligands of killer cell immunoglobulin-like receptor (KIR). Thus it has been valued for their relations to diseases and the functions in transplantation immunity, anti virus and anti-tumor immunity.

Objective To observe the effects of five flavonoids include rutin(RU),dihydromyricetin(DMY),hesperetin(HP),daidzein(DA)and hydroxysaffor yellow A(HYSA)on myocardiocyte apoptosis induced by H2O2 and to explore their relationships with Keshan disease and the possible mechanism.Methods Primary cultured cardiocytes of neonatal rats were randomly divided into control group,model group,and flavonoids preincubation group.The cardiocyte apoptosis was examined by fluorescent staining,the rates of apoptosis were detected by flow cytometry,the expression of Bcl-2 family proteins associated with apoptosis were observed:by Western blot.Results Compared with model group[(24.33±6.51)%],RU[(13.95±3.80)%],DA[(11.82±3.50)%],HYSA[(12.33±3.78)%]could decreased the rate of apoptosis(P＜0.05).The five flavonoids could up-regulate Bcl-2 expression,down-regulate Bax expression,and increase the Bcl-2/Bax ratio[RU(0.989±0.094),DMY(0.931±0.280),HP(0.980±0.095),DA(1.049±0.092),HYSA(1.031±0.039),vs model(0.490±0.046),the difference had statistical significances(P＜0.05)],but the Bcl-xl did not significantly changed(P＞0.05).Conclusions RU,DMY,HP,DA and HYSA have antiapoptotic effects on cardiomyocyte via regulating Bcl-2 and Bax,which gives us a hint in prevention and treatment of Keshan disease.

Objective To study the intestinal flora changes of children with pneumonia,and explore the feasibility and practicability of fluorescent quantitative 16S rRNA/DNA targeted polymerase chain reaction(PCR) in quantitative study of bacterium.Methods The bacterial DNA was extracted in stool between 23 healthy children (control group)and 23 children (pneumonia group)with pneumonia after therapy,A260 of bacteria was detected and compared between 2 groups.16S rRNA/DNA PCR were applied to analyze and compare the bacterial content of lactobacilli and Escherichia coli in stool between control group and pneumonia group.Results Bacterial A260 of stool were respectively(3 381.2?817.2)mg/L in control group,(1 643.5?498.4)mg/L on therapy group post-treatment first day,(859.6?165.2) mg/ L on the third day of post-treatment,(1 263.8?337.3)mg/ L on the 7th day.There were significant differences of bacterial A260 between control group and pneumonia group in post-therapy(Pa

The effects of effective part group on hyperlipidemia in animal were studied. The SD rats, hamsters and Kunming mouse were divided into blank group, model group. The positive control group and test group were fed with normal diet, blank and other groups were fed with high fat diet (mouse only a single intraperitoneal injection of egg yolk ). The corresponding concentration of solvent, simvastatin, effective part group of emulsion were given gavage once daily. The animal serum total cholesterol (TC) , triglyceride (TG) , low density lipoprotein (LDL) , high density lipoprotein (HDL) and liver TC, TG contents were determined to observe the effects of the effective fractions on blood lipid regulating function. Comparing with control group, the animial hyperlipidemia models of the SD rat (TC increase), mouse (TC, TG, LDL increase), hamsters ( TC, TG, LDL increase, HDL decrease) (P <0. 05, P < 0. 001) were successfully established. Piper longum effective part group could decrease the serum TC, TG, LDL (P <0.05, P < 0. 001) and liver TC, TG content, and elevate serum HDL levels (P <0.05, P <0.001). The golden hamster is ideal for hyperlipidemia model.
