Objective To systematically review the current research status of negative pressure wound therapy in China based on method of evidence-based medicine (EBM). Methods A systematic retrieval was undertaken on literatures related to negative pressure wound therapy in China. Evidence grading of EBM and quality rating system of preventive service task force were used for evaluation of the results. Results We finally retrieved five randomized controlled trials (RCT), of which only one RCT was classified as good quality and high grade of evidence, whereas the other four were classified as poor quality and low grade of evidence. Conclusions With relatively wide indications, there still lack sufficient evidences to witness the clinical efficiency of NPWT in China. in the future, we should further researches on NPWT including emphasizing on novelty of research topics and intactness and usefulness of experimental design and standardize clinical application of such technique including standardization of treatment procedures. In the meantime, high quality research papers are needed to provide certain guidance for clinical therapy.

Objective To investigate the allngeneic bone marrow mesenchymal stem cells (mesenchymal stem cells, MSCs) transplantation on cardiac rehabilitation and cardiac function after acute myocardial infarction (AMI). Method Acute myocardial infarction models were made by ligating the left anterior descending coronary artery of rats. A total of 90 rats were randomly divided into the cell transplantation group and control group, 45 rars in each group. Rats in the cell transplantation group were subdivided into 3 groups according to the administration time of the allogeneic bone marrow mesenchymal stem cells (2 weeks, 4 weeks and 12 weeks), and the control group was subdivided the same as in the cell transplantation group. The success criteria included the anterior my-ocardial wall darked and the Sr-segment elevation. The rat femur bone marrow cells were separated using centrifu-gal method, mononuclear cells were isolated by lymphocyte fluid, and the third generation of mesenchymal stem cells were obtained by washing, culture, passage and marked by 4, 6 diacetyl-2-phenyl Indole (DAPI). The ani-mals' chest was opened again a week later, the stem cell suspension was injected into the border zone of infarct area, and the control group was injected with medium. Pre-operative,2 weeks, 4 weeks and 12 weeks after trans-plantation, cardiac function was tested by ultrasonic, myocardial biopsy was observed by HE conventional staining, cardiac stem cells division were observed by immunofluorescence. All data was analyzed by software SPSS 10.0, Independent-Samples T test and Chi-Square test was used, and P≤0.05 was considered as statistically signif-icant. Results The markered hone marrow mesenchymal stem cells were left in the myocardial cells and differen-tiated to eardiomyocyte-like cells. After 12 weeks, the left ventricular internal diameter of rats in cell transplanta-tion group was about (0.58±0.09) mm(P<0.05). Thickness of myocardial infarction zone was (0.25±0.01) mm (P<0.05),ejection fraction was (67.52±0.61) (P<0.05) and left ventricular fractional shortening was (39.86±3.00) (P<0.05). In the transplantation group, the DAPI marked nucleus presented as blue, and the cytoplasm of myocardial cell presented as green. HE staining showed that, in the cell transplantation group, there was less scar tissue and a large proportion of nuclear, similar to the fetal or newhom myocardium cells. Conclu-sions The homogeneus mesenchymal stem cell could repair myocardial infarction and improve cardiac function af-ter infarction.

Objective To explore the feasibility of using Zeocin resistance as a new positive selection marker for the genetic manipulation of Candida albicans (C.albicans).Methods The susceptibility of C.albicans strain CAI4 to Zeocin was determined using a broth microdilution method in pH range from 6.0 to 8.0.The ZeoR expression cassette was amplified from plasmid pGAPZ-α-A by polymerase chain reaction (PCR).An integrated vector used to knockout AAF1 gene was constructed by gene splicing.Then the C.albicans CAI4 was transformed with this integrated plasmid containing the ZeoR expression cassette using lithium chloride method and the target AAF1 gene was replaced.The recombinant C.albicans was screened and the genome was extracted and amplified by PCR with two pairs of primers,then confirmed using genetic method.Results The C.albicans CAI4 was sensitive to Zeocin in pH range from 6.0 to 8.0.And the concentration of Zeoein(100 mg/L) at pH 7.0 was used to select recombined C.albicans.The recombined integrated vector was confirmed by DNA sequencing.The ZeoR expression cassette was detected using PCR method in recombined C.albicans.The AAF1 gene was replaced by ZeoR gene.Conclusion A new vector for targeted gene disruption in C.albicans is successfully constructed.

In recent years, more and more researchers focus on the selectivity of RP-HPLC columns. Among these columns, C18 column is the most commonly used the column. Yet even the same filler can not give us the same separation effect with the columns of different brands and different types, therefore, it is important to choose the suitable HPLC column for carrying out an experiment. After study in recent years, some column classification, selection methods (e.g.: column parameter method, F value method) have been achieved and contributed to the finding of suitable columns and reducing the blindness of column selection. This paper summarizes the advantages of these methods and their limitations in the application process, and gives some advices and expectations to pharmaceutical analysis works based on the works of other researchers.

Objective The incidence of acute pulmonary injury occurred after cardiopulmonary bypass for fallot tetrad has been high. The severity of pulmonary ischemia-reperfusion has been found to be reduced with ulinastatin (UTI) in the animal models and clinical practice. We evaluated the effect of pulmonary artery perfusion with a hypothermic protective solution containing ulinastatin on the inflammatory response in the lung during cardiopulmonary bypass. Methods 30 children with tetralogy of Fallot (TOF) were randomly assigned into control group and protective group, 15 cases in each group. Patients would be excluded if they had signs of infections, such as the white blood cell count was over 12000 per microliter, the temperature was above 38 centi-degree and the c-reaction protein was more than 8 mg/L. Operation with routine approaches was performed in the control group and the pulmonary artery was infused with 4℃ protective solution in the protective group while the heart stoped beating. Plasma tumor necrosis factor α (TNF-α) 、CD11b and Myeloperoxidase (MPO) were measured intraoperatively and postoperatively. Blood gas、pulmonary function and clinic index of the patients were also monitored. Results The level of TNF-α was lower in the protective group as compared with that in the control group immediately and 3 hours after closing the sternum [(11.15±2.47) pg/ml vs. (14.21 ±5.55) pg/ml, P<0.05; (12.01 ±2.69) pg/ml vs. (15.94 ±4.86)pg/ml,P <0.01]. The MFI of CD11b was lower in the protective group as compared with that in the control group at 3 and 6 hoursafter closing the sternum (126.23±36.05 vs. 156.98±48.34, P<0.05; 137.27±38.85 vs. 173.27±67.43, P<0.05). The level of MPO was lower in protective group as compared with that in the control group at 3 hours, 6 hours and 24hours after closing the sternum [(156.52±17.57)U/L vs.(178.45±35.68)U/L, P<0.05; (178.28±23.63) U/L vs.(224.66±49.66)U/L, P<0.01;(130.52±57.50)U/L vs. (96.50±14.49)U/L, P<0.05]. The duration of mechanical ventilation was significantly shorter in the protective group than that in the control group (17.60±6.39 vs. 23.70±8.51,P<0.05). Alveolar-arterial oxygen pressure difference (A-aDO2, calculated as [FiO2×713-5/4×PaCO2]-PaO2) in the protective group was less than that in the control group at 3 and 6 hours after closing the sternum [(120.92±33.08)mm Hg vs. (145.52±39.38)mmHg, P<0.05;(74.76±40.16)mm Hg vs. (112.50±44.16)mmHg, P<0.01]. Dynamic compliance (Cdyn) in protective group was lower than that in control group at 3 and 6 hours after closing the sternum [(0.59±0.11)ml·cmH2O-1·kg-1 vs. (0.46±0.17)ml·cmH2O-1·kg-1, P<0.05;(0.67±0.09)ml·cmH2O-1·kg-1vs. (0.53±0.18)ml·cmH2O-1·kg-1,P<0.05). Conclusion Perfusion with hypothermic protective solution containing UTI to the pulmonary artery during cardiopulmonary bypass may reduce the inflammatory responses substantially in the lung after bypass and had a role in the lung protection.

Objective To evaluate the application of fast track surgery (FTS) in the rib internal fixation of multiple rib fractures. Methods Forty-eight chest trauma with multiple rib fractures patients from March 2008 to March 2010 were divided into FTS group and traditional care group randomly. Meanwhile two groups accepted FTS and conventional management of perioperative period respectively. The degree and duration of the chest pain, early exercise tolerance, intravenous infusion time, the length of postoperative hospital stay,chest scar and postoperative complications were observed and compared between the two groups. Results The duration of chest pain was significantly shorter in FTS group than in the traditional care group([ 112. 46 ±23. 24 ] mins vs [ 180. 23 ± 51.56 ] mins, t = 4. 23 ,P ＜ 0. 05); the early exercise tolerance was longer([ 68. 35 ±9. 30 ] mins vs [ 33.48± 5. 18 ] mins,t = 2. 87, P ＜ 0. 05) ;the intravenous infusion time was shorter ([ 10. 83 ±1.87 ] d vs [ 13. 30 ± 2. 12 ] d, t = 2. 38, P ＜ 0. 05); the length of postoperative hospital stay was shorter([ 12. 35 ± 2.03 ] d vs [ 16. 48 ± 3. 18 ] d, t = 3.04, P ＜ 0. 05); the less postoperative complications(8.3% vs 37. 5 %, x2 = 5. 005,P ＜ 0. 05); chest pain was relieved([ 3.43 ± 0. 45 ] cm vs. [ 6. 62 ± 0. 62 ] cm, P ＜ 0. 05);the scar healed well. All patients were successfully discharged. Conclusion The perioperative idea of fast track surgery was feasible and effective in the chest trauma with multiple rib fractures patients. FTS can improve the patients long term living quality.
