BACKGROUND:The Acinetobacter baumannii group, including Acinetobacter baumannii, Acinetobacter genomospecies 3 and 13TU, is phenotypically indistinguishable and uniformly identified as Acinetobacter baumannii by laboratories of clinical microbiology. This review aimed to demonstrate the differences among them.METHODS:Literatures associated with the Acinetobacter baumannii group were identified and selected from PubMed databases and relevant journals.RESULTS:Acinetobacter genospecies 3 and 13TU possess a certain proportion in clinical isolates. There were considerable differences in epidemiologic features, clinical manifestations, antimicrobial resistances and therapeutic options among theAcinetobacter baumannii group. Compared with Acinetobacter genomospecies 3 and 13TU,Acinetobacter baumannii with a higher resistance to antimicrobial agents are easier to be treated inappropriately, and present a worse outcome in patients.CONCLUSION:The Acinetobacter baumannii group comprises three distinct clinical entities, and their clinical value are not equal.

To ensure the stability of chemistry components and the convenience of operation, ultrasound method was chosen to study in this investigation. As the total common peaks area in chromatograms was set to be evaluation index, the influence on the technology caused by extraction time, ethanol concentration and liquid-to-solid ratio was studied by using single factor methodology, and the extraction technology of Paeoniae Radix Alba was optimized by using response surface methodology. The results showed that the extracting results were most affected by ethanol concentration; liquid-to-solid ratio came the second and extraction time thirdly. The optimum ultrasonic-assisted extraction conditions were as follow: the ultrasonic extraction time was 20.06 min, the ethanol concentration in solvent was 72.04%, and the liquid-to-solid ratio was 53.38 mL · g(-1), the predicted value of total common peaks area was 2.1608 x 10(8). Under the extraction conditions after optimization, the total common peaks area was 2.1422 x 10(8), and the relative deviation between the measured and predicted value was 0.86%, so the optimized extraction technology for Paeoniae Radix Alba is suitable and feasible. Besides, for the purpose of extracting more sufficiently and completely, the optimized extraction technology had more advantages than the extraction method recorded in the monogragh of Paeoniae Radix Alba in Chinese Pharmacopoeia, which will come true the assessment and utilization comprehensively.

Objective The purpose of this study was to investigate the expression of mitochondrial motility-related gene mirol and mitochondrial energy metabolism during an acute bout of prolonged exercise. Methods CS7 BL/6 mice underwent a moderate intensity treadmill running with the slope of 0° and at the speed of 13m/min, and they were randomly divided into 5 groups:resting group(R),exercise groups running for 30min(E30),60min(E60),90min (E90) and 120min(E120),respectively. Respiratory control index and ATP synthesis activity in isolated mitochondria were detected. Skeletal muscle H_2O_2 concentration,mirol mRNA expressions were also measured. Results (1)mirol mRNA contents were significantly increased in groups E30 to E120,as compared with the group R;and mirol mRNA expression increased 32.8%, 107.6%,63.8% and 44.8% respectively in groups E30 to E120. (2)H_2O_2 contents of skeletal muscle were clearly increased in group s E30 to E120. (3)ATP synthesis activity elevated at 30 min of exercise and returned to the baseline thereafter,whereas respiratory control index without remarkable change in groups E30 to E120. Conclusion Muscular mirol mRNA expression significantly increased during 120min of exercise as compared with the resting status and thus facilitated the mitochondrial respiratory and ATP synthesis for matching the energy demand during exercise.

Objective To Discuss the impacts of different dosage of atorvastatirs on serum hsCRP,IL-10 and MCP-1 levels on post-intervention patients with coronary stenting. Methods 93 post-intervention patients with coronary stenting were selected and randomly divided into 3 groups.Each group took different dosage of oral atorvastatins after the operation for more than one week.The dosage for each group was 10 mg,20 mg and 40 mg,respectively.Each patient was phlebotomized for three times,which are 24 hours before the operation,24 hours after the operation and one week after the operation.Serum MCP-1,IL-10 and hs-CRP levels were measured by enzyme linked immunosorbent assay(ELISA)and immunoturbidimetry(ITM). Results Serum hs-CRP and MCP-1 levels of post-intervention patients were significantly higher than those of pre-intervention.This illustrated that the serum hsCRP and MCP-1 levels were closely related to PCI.Serum hs-CRP and MCP-1 levels decreased in those patients one week after operation which proves they are negatively correlated with the dosage of atorvastatins.There was no statistic evidence to prove the correlation between different dosage of atorvastatins and the level of serum IL-10.The ratio of MCP-1/IL-10 at 24h post-intervention patient was significantly higher than pre-intervention,which proves the ratio was negatively correlated with the dosage of atorvastatins. Conclusion Atorvastatins decreases serum MCP-1 and hs-CRP levels after PCI.Serum MCP-1 and hs-CRP levels were negatively correlated with the dosage of atorvastatins.
