Objective To investigate pathogens distribution and their drug resistance of hospital acquired pneumonia (HAP) in local elderly paraplegic patients,and to help to gain experience in early using antibiotics.Methods One hundred and thirty six elderly patients diagnosed as HAP from January 2007 to December 2010 in our hospital were selected.Pathogens distribution and their drug resistance were detected.Results One hundred and fifty two pathogens are isolated from the 136 patients,and most of them are gram negative bacteria which accounts for 70.4%.The first three pathogens are Klebsiella pneumonia(24.3%),Escherichia coli (20.4%) and Pseudomonas Aeruginosa (18.4%).Gram-positive cocci accounts for 25.0% in total pathogens,among them,staphylococcus aureus and streptococcus pneumoniae account for the most,and the number of Fungi is the fewest.Drug resistance rate of gram-negative bacteria is higher than that of Gram-positive bacteria.Gram-negative bacteria has higher resistance to ampicillin,cefoperazone,ciprofloxacin,levofloxacin and eotrimoxazole.Gram-positive bacteria has higher resistance to penicillin,cefazolin and gentamicin.Conclusion To elderly paraplegic HAP patients,the main pathogenic flora is gram-negative bacterium which shows multiple resistances.Being familiar with the features of pathogens and their drug resistance will provide better guidance on early treatment and improve prognosis of elderly paraplegic HAP patients.

Objective To study the main influence factors of nosocomial infection(NI) and establish a model to predict and forecast the risk of NI on patients in hospitals. Methods Clinical data of 27352 inpatients extracted from hospital information system were sorted out and coded, and a logistic regression model about the probability of NI was established. The risk of NI was divided into four scales. Results With multiple factor analysis,16 risk factors of NI were identified, which were age, high body temperature, numbers of diagnosis, days of staying in hospital and seriousness, numbers of routine test for urine, times of blood transfusion, use or without use of antibiotic and radiotherapy, turning over the bodies or not, relationships between infection and interventional operations, with or without diabetes, categories of diseases based on ICD-9, numbers of interventional operations, type of anesthesia and department of admission. If NI was judged when predicted probability(Pr)of logistic regression model exceeded 0 35, the specificity and false diagnostic rate of diagnostic test were 0 995 and 0 005 respectively, and the area under ROC curve was 0 986. According to decision tree method, the risk of NI was classified into four degrees: low (Pr

Objective To study the uptake property of punicalagin in Caco-2 cells.Methods Caco-2 cell monolayer model was used to research the effects of punicalagin on cell uptake in different times, concentrations, pH values, temperatures and P-gp inhibitors. HPLC was used to determine the content of punicalagin in cells.Results The linearity of punicalagin concentration curve was found in the range of 0.024 8-0.992μg (r=0.997 9). Uptake determination of punicalagin in Caco-2 cells absorbed a certain amount of time, concentration and pH dependence and P-gp inhibitors could significantly increase the punicalagin uptake.Conclusion This method is simple and sensitive to determine the punicalagin concentration in Caco-2 cells, which is mainly passively transported. P-gp is involved in punicalagin transport process.

Objective: Based on optimized method of DNA ligase chain reaction in medium/low throughput genotyping, we assessed the relationship between NOD-like receptor genes NOD1, NOD2 and coronary artery disease (CAD) occurrence. Methods: A multiplex PCR was conducted to enrich DNA template; probe design, annealing temperature, time and number of circulation of PCR were opfimizecl for allele specific ligation; allele specific products were identified by fluorescence PCR and capillary electrophoresis; the accuracy was verified by Sanger sequencing. Single nucleotide polymorphisms (SNPs) on NOD1 gene and NOD2 gene were examined in 1555 CAD patients and 1887 control subjects; the relationship between SNPs and CAD occurrence was studied. Results: Based on optimized PCR condition and allele specific probe design, 30 allele loci genotyping can be genotyped by 10ng DNA template at one time. Association study presented that rs751271 and rs1861759 on NOD2 gene were related to non-hypertensive CAD, allP<0.05; with Bonferroni correction, such correlation was still significant, allP<0.05. Conclusion: We optimized DNA ligase chain reaction and established a novel high accuracy, low cost method for the demand of medium/low throughput genotyping in clinical molecular diagnosis. With this method, we identified that rs1861759 and rs751271 on NOD2 gene were associated with non-hypertensive CAD.

OBJECTIVE:To study the pharmacokinetic characteristics of Puerarin solid self-microemulsion capsules in rats in vi-vo. METHODS:The rats were randomly divided into two groups with 18 rats in each group. They were given Puerarin solid self-mi-croemulsion capsules(S-SMEDDS capsules)and commercially available Yufeng ningxin tablet,with the dose of 158.15 mg/kg puer-arin. The 0.2 ml blood samples were collected from tail vein 0,5,10,20,40,60,90,120,180,240,360,480,600 min after medication,respectively. The blood concentration of puerarin was determined by HPLC,and pharmacokinetic parameters and rela-tive bioavailability were calculated by using 3p87 software. RESULTS:The metabolism of puerarin was one-compartment model in rats. Pharmacokinetic parameters of S-SMEDDS capsules and Yufeng ningxin tablet were as follows as cmax of (1.032 0 ± 0.020 6) and(0.587 3±0.011 7)μg/ml,t1/2ke of(116.431 4±2.166 0)and(88.222 6±1.752 4)min,AUC0-t of(261.532 2±1.464 0)and (102.835 5±1.957 4)μg·min/ml. Relative bioavailability was 238.77%. CONCLUSIONS:Compared with Yufeng ningxin tablet, S-SMEDDS capsules are absorbed more completely and removed faster.

Objective To analyze factors affecting quality of life (QOL)in patients with chronic hepatitis B (CHB),and provide reference for improving QOL of patients. Methods The MOS 36-item short form health sur-vey (SF-36)was adopted to survey QOL of patients with CHB,Morisky medication adherence scale was used to measure patients'adherence to medication,factors affecting QOL of patients with CHB were analyzed. Results Of 357 CHB patients,271(75.91% )were married,107(29.97% )received college or above education,163(45.66% ) patients'average household monthly income were ¥ 2000-¥ 5000,138(38.66% )patients'family members were also with CHB,198 (55.46% )patients smoked,150 (42.02% )drank. The average score of CHB patients' adherence to medication was (2.15±1.29). Factors affecting QOL in patients with CHB were age,education level, duration of disease,whether or not hospitalized,whether or not drink,as well as adherence to medication. Age, drink,and duration of hepatitis B,and previous hospitalization were negative factors affecting QOL in patients with CHB,education level and adherence to medication were positive factors affecting QOL in patients with CHB. Conclusion Strengthening CHB patients'understanding on disease and improving their medication adherence can help them to improve QOL.
