Objective To compare the effect of Baikerui compound lysostaphin (FE complex phosphoesterasum) disinfectant and povidone iodine in treatment of burn wound infection resulted from gram-positive (G ±) coccus.Methods The study involved 60 patients with superficial second degree burns (1％-5％ TBSA； age range of 18-50 years).All the patients received bacterial culturing of wound secretions prior to treatment.Every 20 patients were indentified with infection of staphylococcus aureus (SA),staphylococcus epidermidis (SE),and enterococcus (EC) respectively and randomized into control group and experiment group,with 10 patients per group.Patients allocated to the experiment group were covered with four-layer sterile gauze soaked into the Baikerui compound lysostaphin disinfectant,while the patients in the control group were treated with four-layer sterile gauze soaked into the povidone iodine.Dressing was changed once a day.Wound culturing was performed again at each day of the 5-day treatment.Wound healing was compared among each group.Results SA wound infection turned negative for all the 10 patients in experimental group and three patients in control group (P ＜ 0.01).SE wound infection turned negative for all the 10 patients in experimental group and six patients in control group (P ＜ 0.05).EC wound infection turned negative for nine patients in experimental group and seven patients in control group (P ＞ 0.05).Mean wound healing time was (10.87 ± 1.93) days for experimental group and (13.31 ± 2.89) days for control group (P ＜ 0.05).Conclusion Baikerui compound lysostaphin disinfectant can effectively prevent burn wound infection with common G + coccus and accelerate wound healing.

Objective:To study the distribution of flurbiprofen axetil ( FA) microemulsion in rats and evaluate the targeting prop-erty to traumatic inflammation tissue. Methods:Traumatic injury model rats were established by hip surgery on the rat right thigh mus-cle and randomly divided into 2 groups:microemulsion group and solution group. Serums and tissues of rats were collected at 15, 30, 60, 120 and 240min after administration (iv. 5 mg·kg-1). A high performance liquid chromatography (HPLC) with UV detection was developed to study the concentration of flurbiprofen in biological samples. Results: The elimination of flurbiprofen axetil microe-mulsion from blood and tissues was slower than flurbiprofen solution. At each 5 time points, drug concentrations of microemulsion group in injury muscle were higher than in normal muscle (P<0. 05), while solution group had no significant difference(P>0. 05). Micro-emulsion group injury muscle Te(targeting efficiency) =12. 21%, and the solution group Te =3. 97%. The Re (relative uptake rate) of injury muscle was 4. 15. Conclusion:The flurbiprofen axetil microemulsion has the targeting property to traumatic injury tissues.

Objective To investigate DNA double-strand breaks and radiosensitization in renal carcinoma 786-O cells induced by fludarabine (FA) combined with different ionizing radiations.Methods The 786-O cells were exposed to FA combined with X-ray or heavy ion beam irradiation.Flow cytometry was used to evaluate the percentage of γH2AX-positive cells and cell cycle.The neutral comet assay was used to detect DNA double-strand breaks.The colony-forming assay was used to evaluate the effects of different treatments on cell survival.Comparison between groups was made by one-way analysis of variance or Dunnet' s t test.Results Compared with FA alone or irradiation alone,FA combined with different ionizing radiations increased DNA double-strand breaks as shown by significantly increased levels of γH2AX (P=0.007,0.001);FA combined with heavy ion beam irradiation lead to a cell cycle block at the radiosensitive G2/M phase and significantly increased the expression of γH2AX in the G2/M phase (P=0.000,0.000);the neutral comet assay revealed that FA combined with irradiation significantly increased DNA sublethal damage (P=0.020,0.060);FA significantly reduced the colony-forming rate after irradiation (P=0.000,0.030;0.001,0.040).Conclusions FA enhances the effects induced by X-ray and heavy ion beam irradiation with different properties.Particularly,FA substantially enhances the cell death induced by heavy ion beam irradiation.

Objective To evaluate the clinical advantages of transradiai approach for percutaneous coronary intervention in elderly patients with acute myocardial infarction.Methods From January 2008 to October 2011,150 elderly patients (average age of 70.4±7.2 yrs) diagnosed with acute ST-segment elevation myocardial infarction underwent primary percutaneous coronary invention (PCI).They were divided into transfemoral intervention group (TFI group,n=91) and transradial intervention group (TRI group,n=59).The arrival time at the first balloon inflation,the success rate of reperfusion,the X ray exposure time,the total procedural time,contrast volume,the average in-hospital days,the mean hospital expenses and postoperative complications were compared between two groups.Results The average in-hospital days was shorter in TRI group than in TFI group [(9.3±0.5) days vs.(12.8±0.7) days,P＜0.01].The mean in-hospital expenses was less in TRIgroup than in TFI group [(44707.3±1009.3) RMB vs.(54047.8±1971.6) RMB,P＜0.05].There were no significant differences in the arrival time at the first balloon inflation,the success rate of reperfusion,the X-ray exposure time,the contrast volume between the two groups [(26.7±0.8)minutes vs.(27.7±1.2) minutes,98.3％ (58/59) vs.96.7％ (88/91),(10.8±0.9) minutes vs.(9.6±0.6) minutes,(223.9±9.2) ml vs.(229.8±7.5) ml,respectively,all P＞0.05].The postoperative complications including major bleeding,pseudoaneurysm,radial occlusion without ischemia and the incidence of major adverse cardiovascular events had no statistical differences between the two groups (P＞0.05).The cases of urethral catheterization caused by urinary retention were less in TRI group than in TFI (0 vs.11 cases,P＜0.01).Conclusions Compared with transfemoral approach,the transradial approach is feasible and safe for primary PCI in elderly patients with acute myocardial infarction,and has better clinical advantage and socioeconomic benefit.

Lung cancer is currently one of the most common malignant tumors in the world. The occurrence and development of lung cancer, especially non-small cell lung cancer (NSCLC), are closely related to the abnormal expression of long non-coding RNA (lncRNA). lncRNA with a transcript of more than 200 nucleotides is involved in chromatin modification, transcription activation, transcription interference and other regulatory processes, and has varying degrees of regulation on the proliferation, migration, and invasion of tumor cells. It is characterized by up-regulation or down-regulation of expression. At present, there are a large number of studies on lncRNA, because lncRNA has considerable application prospects in the diagnosis, clinical treatment, drug resistance research and prognosis evaluation of NSCLC. In this paper, the overview of lncRNA, the up-regulation or down-regulation of NSCLC-related lncRNA expression, NSCLC clinical treatment and drug-resistant lncRNA were summarized.

For the defects of interpreting the relationship between the distribution and severity of vascular stenostic disease and the low shear stress, the study focus on and explore the rules of the pressure distribution and variation downstream of the stenostic vessel with the numerical simulation and the hydrodynamic model of turbulent flow separation area for in vitro experiment. The results reveal that there is a good compatibility between the model experiment and the numerical simulation; there exists a marked pressure decrease downstream of the stenosis. And the distribution area of low pressure is similar to the characteristic distribution of the stenostic vessel diseases. The study suggested that the numerical simulation can be applied in the study of micro-flow field; the presure distribution and variatioin downstream of the stenostic vessel maybe another factor to trigger the pathogenesis of vessel stenostic diseases.
