Objective To investigate the early prediction,diagnosis and treatment of thoracic injury complicated by adult respiratory distress syndrome (ARDS).Methods The blood gas,occurrence index of traumatic ARDS,pathogenic bacteria and drug sensitivity in ventilator associated pneumonia (VAP) were analyzed retrospectively in 18 cases of thoracic injury.Results The initial PaCO 2 was (32.1?5.2) mm Hg,PaO 2 (57.7?10.1) mm Hg,the occurrence index of traumatic ARDS (-29.00?11.50) and the mechanical ventilation time 6.4 days on average.Of the infective bacterium of VAP,gram negative bacterium took up 70.6%, gram positive bacterium 17.10%,fungus 12.30% and the mixed infection 31.60% with the total mortality of 16.6%.Conclusion The occurrence index of traumatic ARDS can be used as a parameter of the early prediction and outcome.Meanwhile multiple injuries and shock should be treated correctly,ventilator applied earlier and the mechanical ventilation time shortened.It suggests that more attention should be paid to the prevention of VAP and the reasonable use of antibiotic drugs.

Aim To study the protective effect of tetra-hydroxystilbeneglucoside ( TSG ) on cardiac injury and the mechanism involved in silent mating type informa-tion regulation 2 homolog 1 ( SIRT1 ) and adenosine monophosphate-activated protein kinase( AMPK) in the diabetic rats. Methods Type 2 diabetic rats were sac-rificed after administration with TSG for 8 weeks. Blood glucose, blood lipids, liverfunction,creatine ki-nase ( CK ) , lactate dehydrogenase ( LDH ) as well as myocardial nonesterified fatty acids( NEFA) were deter-mined by using biochemical test. The concentration of myocardial fatty acid transport proteins ( FATPs ) and-fatty acid β-oxidase ( FA-β-oxidase ) , and the levels of tumor necrosis factor alpha ( TNF-α) , interleukin -6 ( IL-6 ) , interleukin-1β( IL-1β) in serum were also measured by ELISA method and radio immunoassay re-spectively. The protein expressions of TNF-α, IL-6, IL-1β, SIRT1 and AMPK were detected by Western blot. Results Treatment of TSG reduced the contentof blood lipids, NEFA and collagen without affecting the content of blood glucose and insulin. The levels of TNF-α, IL-6 and IL-1βin serum as well as the protein expressions of TNF-α, IL-6 and IL-1β of cardia were also inhibited by administration with TSG. Treatment of TSG caused a significantly increased concentration of myocaidial FATPs and FA-β-oxidase, and dramatically restored the decreased protein expressions of SIRT1 and pAMPK in diabetic rats. Conclusion The protec-tive mechanisms of TSG against diabetic rats are in-volved in the alleviation of inflammatory mediator injury and improving energy metabolism.

Objective To determine the incidence rate of HPV infection or multi-infections at different stages of cervical lesions in the development of cervical cancer , and the impact of specific types of HPV multi-infections on the risk of cervical cancer. Methods 103 samples of cervical tissues were detected and then divid-ed into ICC/HSIL group and LSIL/NILMF group according to the degree of pathological changes. HPV type was determined by PCR product sequencing. E6 nested multiplex PCR was performed to detect HPV multi-infections. Odds ratios were calculated to determinate the association between the sample category (LSIL/NILM or ICC/HSIL) and the specific types of HPV multi-infections. Results In HPV-positive samples, the rate of multi-in-fections had no significant differences between the two groups. Coinfection of HPV68 with HPV16 increased the risk of ICC/HSIL, as compared with HPV16 or HPV68 infection alone. Conclusions High-risk HPV coinfec-tions has a higher risk to induce ICC/HSIL than does HPV infection alone.

Objective To explore the application of particle-gun technique in transfecting dendritic cells(DCs),and investigate the expression of DNA vaccine particle IgHV1-GM-CSF in DCs induced by particle-gun.Methods Monocytes were isolated from donor peripheral blood collected by Ficoll density gradient method and adherent culture,and then differentiated into immature DCs(imDCs) by rhGM-CSF and rhlL-4 induction.The plasmids for transfection were IgHV1-GM-CSF/pcDNA3.0 and pEGFP,which were prepared with endofree plasmid purification kit.The DCs were transfected with plasmid pEGFP by particle-gun at different transfection conditions,the green fluorescence positive cell and the total cell numbers were counted respectively under fluorescence microscope,and the transfection efficiency was calculated;the viable cell count was performed after trypan blue staining;the transfection efficiencies of particle-gun,liposome-mediated transfection and electroporation method were compared.The plasmids IgHV1-GM-CSF/pcDNA3.0 and pEGFP were cotransfected into imDCs by particle-gun under the optimum conditions,and then DNA was extracted,the expression of IgHV1-GM-CSF was determined by RT-PCR,and of GM-CSF by ELISA.Results The optimum conditions of particle-gun transfection in imDCs were: gas pressure at 120psi,PVP concentration in 0.02mg/ml,microcarrier loading in 0.5mg gold/shot,and DNA loading ratio in 1.5?g plasmid/mg gold.The transfection efficiencies of particle-gun and electroporation were 10.5%?2.4%(n=3) and 45.2%?5.6%(n=3) respectively,while that of liposome-mediated transfection was very low,and significant difference existed among the three methods(P

Objective: To explore the effects of cardiac resynchronization therapy (CRT) in patients with dispersion of re-polarization and ventricular arrhythmia.
Methods: A total of 86 consecutive patents with CRT implantation were enrolled. According to weather absolute value of LVEF increased≥10% from baseline at 6 months after CRT implantation, the patients were divided into 2 groups: Response group and Non-response group,n=43 in each group. Dispersion of re-polarization indexes as QRS duration, QTc interval, TpTe interval and the events of ventricular arrhythmia were compared between 2 groups at different time points after CRT.
Results:①In Response group, compared with pre-operation, QRS duration and TpTe interval were shorter at 1 year and within 24h after CRT implantation, allP<0.05, while the above indexes were similar in Non-response group, allP>0.05.②During 1 year after CRT implantation, the incidences of PVCs and PVC runs in Response group were much less than those in Non-response group, for lgPVCs: (1.78 ± 0.77) vs (2.73 ± 0.61), for lgPVC runs: (0.64 ± 0.48) vs (1.98 ± 0.72),P<0.05.③Multi liner regression analysis demonstrated that TpTe interval within 24h after CRT implantation was an independent predictor for both lgPVCs: (B=0.143, OR=1.154,P=0.001) and lgPVC runs: (B=0.122, OR=1.047,P=0.001).
Conclusion: CRT ventricular reverse remodeling may reduce dispersion of re-polarization and the risk of ventricular arrhythmia, therefore improve the prognosis in relevant patients; TpTe interval within 24h after CRT had the predictive value for ventricular arrhythmia.

BACKGROUND: Mesenchymal stem cells are the stem cells that possess the capability for self-renewal and multi-directional differentiation. Umbilical cord is the tissue outside the embryos and would be fallen off after parturition. In addition, it has wide source and no ethical restriction, so it is promising to be the first choice for mesenchymal stem cells. OBJECTIVE: To detect the surface markers CD29, CD44, CD49e, CD73, CD90, CD34, CD45, and CD271 of human umbilical cord-derived mesenchymal stem cells (hUCMSCs) prior to and after cryopreservation and resuscitation. METHODS: After isolation and culture, morphology of the primary, P4 and P8 hUCMSCs was observed prior to cryopreservation and after resuscitation. Surface markers CD29, CD44, CD49e, CD73, CD90, CD34, CD45, and CD271 of primary, P4, and P8 hUCMSCs were detected through the use of flow cytometry prior to cryopreservation and after resuscitation RESULTS AND CONCLUSION: hUCMSCs prior to cryopreservation and hUCMSCs of different passages after resuscitation present the same phenotype, i.e., positive for CD29, CD44, CD49e, CD73, and CD90, and negative for CD34, CD45, CD271. These findings suggest that primary hUCMSCs do not present changes in surface markers after cryopreservation and resuscitation.
