Aldehyde oxidase (AOX), a highly conserved molybdoflavoenzyme in mammal cytoplasm, has broad substrate specificity and ability to catalyze the oxidation of aldehydes and nitrogen, oxygen-containing heterocyclic rings. AOX was found to widely distribute with the individual differences in vivo and plays an important role in phase I metabolism of drugs and xenobiotics. The biological characteristics of AOX and its contributions in drug metabolism are introduced briefly in this review.

Objective To understand the drug resistance in cancer patients with secondary non-fermenting bacterial lower respir-atory tract infection in order to provide a basis for clinical rational use of antibacterial drugs.Methods The lower respiratory tract specimens were collected from the patients with malignant tumor and identified by the fully automated microbial identification sys-tem,the drug susceptibility test was performed by using K-B method and the drug susceptibility test results were judged according to CLSI 2012 standard.The data were analyzed by the WHONET 5.6 software.Results 172 strains of non-fermenting bacteria were isolated from the lower respiratory tract specimens in the patients with malignant tumors,in which Pseudomonas aeruginosa was maximum,accounted for 45.9%,followed by Acinetobacter baumannii and Stenotrophomonas maltophilia ,accounted for 36. 0% and 10.5 % respectively.The drug susceptibility test showed that five kinds of non-fermenter demonstrated the high resistance or multi-resistance to multiple antibacterial drugs.Conclusion Non-fermenting bacterial multi-drug resistant phenomenon is seri-ous,clinic should pay attention to non-fermenting bacterial infection and drug resistance monitoring,antibacterial drugs should be rationally used according to the drug susceptibility test results in order to reduce the generation of drug-resistant strains.

BACKGROUND:In the whole world, spinal cord injuries caused by trauma lead to more than 180 000 people presenting with permanent impairment annualy. A large number of experiments have confirmed in recent years, under physiological conditions, microRNA has specific expression and plays an important role in the nervous system. OBJECTIVE: To discuss the changes in microRNA expression induced by injuries as wel as the pathophysiological significance in spinal cord injury, and to explore the development potential of microRNA in tissue-engineered and clinical repair of spinal cord injury. METHODS:A computer-based search of PubMed and Chinese Journal Database was performed for related articles published from January 2000 to December 2014 using the keywords of “SCI, microRNA, transcriptional control, clinical research progress” in English and Chinese. Finaly, 38 articles were included for result analysis. RESULTS AND CONCLUSION: Mechanical injury initialy triggers a series of complex secondary damages, including nervous, vascular and immune systems, which can influence the severity of spinal cord injury to a great extent. Secondary damage to the spinal cord is mainly attributed to the activation and deactivation of some specific genes associated with celular and biochemical mechanisms, such as cysteine aspartate specific protease (caspase) gene family, apoptosis related protein Fas and its ligand Fasl system, P53 gene, apoptosis related gene Bcl-2 family. Recent studies have proved that the functional activation of microRNA expression is the key to spinal cord injury. With the development of biological information engineering, studies and controling technologies associated with microRNA expression have been gradualy dominated, some clinical application based on microRNA technology has entered the clinical trial stage. It is believed that with the continuous development of technology and decrease of cost, permanent dysfunction due to spinal cord injury can be regulated and repaired through the microRNA technology at gene level in the future.

The chemical constituents of starfish Asterias amurensis have been extensively studied in China. Some unique and new chemical constituents have been isolated from Asterias amurensis ; they included saponins, sulfated sterols, amyloses, steroids, amino acids, etc. Many of them have anti-bacterial activities and hemolysis effects. We reviewed the related literatures published home and abroad, hoping to provide more evidence for further development of Asterias amurensis.

Objective To analyze and compare the HBV DNA contents in serum and breast milk after injection of hepatitis B im‐munoglobulin (HBIG) in different periods of pregnant and lying‐in women to provide the experimental basis for blocking the mater‐nal‐neonatal transmission(PMTCT) and breast feeding scheme .Methods 140 pregnant women carrying hepatitis B virus with HB‐sAg(+ ) by antenatal examination in the obstetric outpatient department of our hospital from June 2012 to June 2014 were selected and divided into the research group and the control group according to the voluntary and secretive principle .Among them ,75 cases in the research group were intramuscularly injected by high titer HBIG 200 U at 28 ,32 ,36 weeks of pregnancy ,while 65 cases in the control group were injected by HBIG at the end of pregnancy due to different causes .Serum HBV‐DNA content before injection and before delivery was detected in the two groups ,and which in neonatal serum and breast milk within 3-5 d also detected .The differences and correlation between the two groups were analyzed .Results The HBV‐DNA content <500 copies/mL ,500-1 × 106 copies/mL ,>1 × 106 copies/mL before HBIG injection in the research group were 28 cases ,17 cases ,30 cases respectively ,which before delivery were 35 cases ,20 cases ,20 cases respectively ;which in antenatal twice detection in the control group were 19 cases , 21 cases ,25 cases and 20 cases ,17 cases ,28 cases respectively ;neonatal serum HBV‐DNA positive in the research group and control group had 1 case(5 .3% ) and 5 cases (7 .7% ) respectively ;the breast milk HBV‐DNA positive in the two groups had 3 cases(4% )/and 8 cases(12 .3% ) respectively .Conclusion HBIG injection at late pregnancy in the pregnant women carrying HBV could influ‐ence the HBV replication ,thus reduces the probability of neonatal intrauterine infection ,at the same time reduces the HBV‐DNA positive rate of postpartum breast milk .

Objective To analyze the clinical characteristics and resistance to commonly used antibacterial drugs in the intensive care unit(ICU)patients with hospital-acquired Burkholderia cepacia infection in order to provide the basis for clinical rational treatment.Methods The drug resistance situation in 32 strains of Burkholderia cepacia isolated from the bacterial culture speci-mens submitted by ICU of our hospital from January 2011 to December 2012 was performed the retrospective analysis.Results In the detection sites,the infection was mainly distributed in the lower respiratory tract (62.5%),followed by deep venous catheter (12.5%);the drug susceptibility test revealed that 32 strains of Burkholderia cepacia showed the natural resistance to multiple antibacterial drugs,but which were still sensitive to minocycline,chloromycetin,meropenem,ceftazidime,cefoperazone/sulbactam, these drugs could be used as the first choice of drugs for treating Burkholderia cepacia infection.Conclusion The drug resistance phenomenon of Burkholderia cepacia is very serious in the ICU patients.Clinic should pay great concern to the infections caused by multi-drug resistant Burkholderia cepacia ,the microbiological testing should be conducted as early as possible,and the antibacterial drugs should be rationally selected according to the drug susceptibility testing results.
