Purpose:To investigate the relation between the expression of cyclinB1 gene and drug resistance in patient with acute leukemia. Methods:Cyclin B1 gene mRNA expression in 13 cases of drug resistant and 14 drug non-resistant acute leukemia patients’ peripheral blood have been determinated by semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR).The expression of mdr1 gene mRNA in these patients was measured with fluorescence -quantitative reverse transcription-polymerase chain reaction (RT-PCR). Results:The expression of cyclin B1 mRNA in the drug resistant group was significantly higher than the drug non-resistant group cyclin B1 mRNA (P

Objective Analyzing the distribution of 1476 strains of clinical common pathogens and their antimicrobial resistance, provide reference the reasonable use of antimicrobial drugs for clinical.Methods Using BD company PHOEIX-100 Automatic Pathogen Identification to Pathogen identify 1476 strains of pathogens which were got from the various isolated and cultivated samples which were examined from 2009 January to 2010 August and its antibacterial Drug Susceptibility Test, then with WHONET5. 3 system to analyze monitoring data of the pathogen distribution and resistance. Results In 1476 strains of pathogens isolated, gram-negative bacteria had 1206 strains occupying 81.7% ; Gram-positive cocci had 270 stains occupying 18. 3%. The most common detected pathogen were Escherichia coli, Klebsiella pneumoniae,Staphylococcus aureus and Pseudomonas aeruginosa, which accounted for 20. 2% ,17. 5% ,13. 2% ,11.4%.The ESBLs producing E. coli and K. pneumoniae accounted for 65. 9% ,48. 1% ; Also methicillin-resistant S. aureus (MRSA) accounted for 79. 2% and methicillin-resistant coagulase-negative staphylococci (MRCNS) accounted for 68.4%. It isnt found yet that grape genus to vancomycin, nitrofurantoin can resist drug.Gram-negative bacilli to antimicrobial vinyl hydrocarbon mold degree of sensitivity is high. Conclusion The isolated pathogen's resistance of drug is widespread. It is important to guide clinical reasonable use of antibiotics and control infectious pathogens that carry out continuous monitoring of drug resistance.

Objective To study the combined effect of chlorotoluron and atrazine on the testis of mice. Methods Kunming mice were divided into groups and treated with chlorotoluron and atrazine alone or in combination by gavage at different doses for 25 consecutive days. Microscope and electron microscope were used to observe the morphological changes. Results The herbicides used alone or in combination, at all the test doses, caused the morphological changes in degrees in the testis. Under the light microscope, seminiferous epithelium arrayed loosely and disorderedly, spermatogenic cell shed, and layers lessened compared with the control group. Under the electron microscope, mitochondria in the seminiferous epithelium appeared vacuolated, karyotheca swelled, bent and the function of sustentacular cell declined. Compared with alone use groups, the pathological changes were more serious in combination use groups. Conclusion Chlorotoluron and atrazine can produce a combined toxic effect on the testis of mice.

OBJECTIVE： To develop a HPLC method for the determination of the contents of lidocaine and prilocaine in compound lidocaine cream as a quality control means.METHODS： Lidocaine and prilocaine in compound lidocaine cream were determined by high-performance liquid chromatography on C18 column with the detection wavelength at 254nm.The mobile phase was 0.5％ ammonium dihydrogen phosphate(pH=7)-methanol(20∶ 80).RESULTS： The calibration curves of both lidocaine and prilocaine were linear within the concentration range of 130～250μ g/ml(r=0.9 996).The recovery rates of lidocaine and prilocaine were 99.05％ and 99.27％ respectively， RSDs were 0.67％ and 1.15％ ， intra-day RSDs 0.81％ and 1.45％ ， inter-day RSDs 0.55％ and 0.63％ respectively.CONCLUSION： The method was sensitive， stable and accurate.It can be used to determine and control the quality of compound lidocaine cream.

Objective To observe the influence of weight - lost therapy on obese children with impaired glucose tolerance( IGT), insulin resistance. Methods Fasting,post- prandail 2 hours blood glucose and insulin were measured in 14 obese children (age 8 - 15 years) with IGT before and after two - month weight - lost iherapy. Glucose were measured with enzymeoxidize assay, and insulin were measured with radio-immunity assay(RIA). Results Among 14 obese children with IGT, after two-month weight - lost the-rapy, there were 9 children becoming normal OGTT. There were significantly lower in the concentration of fasting insulin and post - prandail 2 hours blood insulin and glucose[(14.23?2.35) mIU/L,(47.20?10.26) mIU/L,(5.36?0.91) mmol/L] than before weight -lost therapy[ (32.54?7. 13) mIU/L,( 164.53?33.60) mIU/L, (8.75?1.09) mmol/L](P

Objective To investigate the drug resistant genes and genotypes of carbapenem-resistant Klebsiella pneumoniae in Tianjin First Center Hospital. Methods A total of 52 strains of carbapenem-non-susceptible Klebsiella pneumoniae were collected from 2012 to 2015. The MICs of antimicrobial drugs were detected using agar dilution methods. Phenotypes of carbapenemases were screened using modified Hodge test. Drug resistant genes were detected by multiplex-PCR assay. Multilocus sequence typing ( MLST) was used to determine the genotypes and homology of these carbapenem-resistant Klebsiella pneumoniae strains. Results Susceptibility of antimicrobial agents indicated that all these strains with multiple drug resistance. The resistance rate to piperacillin/tazobactam, ceftriaxone, ceftazidime, cefepime, aztreonam imipenem,meropenem was 100%( 52/52 ) . The resistance rate of ST11 type to amikacin was 93. 5%( 43/46), ciprofloxacin was 97. 8%(45/46), levofloxacin was 97. 8%(45/46), compound sulfamethoxazole was 17. 4%(8/46), tigecycline was 0. The resistance rate of ST101 type to amikacin was 3/3, ciprofloxacin was 2/3, levofloxacin was 3/3, compound sulfamethoxazole was 3/3, tigecycline was 0. The resistance rate of ST709 type to amikacin was 1/1, ciprofloxacin was 1/1, levofloxacin was 1/1, compound sulfamethoxazole was 1/1, tigecycline was 0. The resistance rate of ST1393 type to amikacin was 1/1, ciprofloxacin was 1/1, levofloxacin was 1/1, compound sulfamethoxazole was 1/1, tigecycline was 0. The resistance rate of ST2068 type to amikacin was 1/1, ciprofloxacin was 1/1, levofloxacin was 1/1, compound sulfamethoxazole was 1/1, tigecycline was 0. PCR results showed that 43 isolates were blaKPC-2 positive and 5 isolates were blaOXA-48 positive, 1 isolate was blaDNM-1 positive. There were 46 strains of ST11 type. The 43 strains of Klebsiella pneumoniae producing KPC-2 type carbapenemase were all ST11. While among 5 strains of Klebsiella pneumoniae carrying OXA-48 carbapenem resistant gene, 3 strains were ST101, 1 was ST709, 1 was ST1393. One strain of Klebsiella pneumoniae harboring DNM-1 type carbapenemase was ST2068. Conclusions Drug resistant genes of carbapenem-resistant Klebsiella pneumoniae were KPC-2 dominant, OXA-48 and DNM-1 were sporadical;the genotype was mainly ST11 by MLST in the hospital. The research provided effective basic and reference for the hospital infection t control.
