Objective To explore the changes of TGF-? and GM-CSF in rats with experimental bronchial asthma of spleen-deficency and the regulatory effect of acupuncture at Zusanli. Methods The rat models with spleen-deficiency in TCM and bronchial asthma in West Medicine were set up. They were given acupuncture at Zusanli. The concentration of TGF-? and GM-CSF in BALF were detected by enzyme linked immuoabsorbent assay (ELISA) and apoptosis was detected by TUNEL. Results Compared with the asthma group, the count of EOS and the levels of GM-CSF increased (P

Objective:To study the expressions of E-cadherin(E-cad) an d CD44V6 in normal oral mucous,oral atypical hyperplasia and oral squamous cell carcinoma(OSCC).Methods:The expression of E-cad and CD44V6 in 1 7 cases of normal oral mucous,6 of oral atypical hyperplasia and 52 of OSCC was examined with immunohistochemistry. Results: E-cad expression was observed in all the cases of normal oral mucous and oral atypical hyperplasi a,and in 43/52( 82.69% ) of OSCC. CD44V6 expression was observed in all the ca ses of normal oral mucous and oral atypical hyperplasia,and in 32/52(61.54%) of OSCC.In OSCC, the expression of E-cad was decreased with the decrease of differ entiation degree(P

Objective To investigate and compare the change of extravascular lung water (EVLW) and levels of cytokines in septic patients without clinical acute lung injury (ALI) /acute respiratory distress syndrome (ARDS) with those in spetic patients with sepsis-induced ALI/ARDS in order to determine the role of EVLW involved in the pathogenesis of lung injury in the patients by quantifying the relationship between EVLW and biomarkers of lung injury in patients with sepsis.Methods A total of 40 septic patients complicated either with or without clinical ALI/ARDS after sepsis. In each patient,transpulmonary thermodilution (PiCCO) was used to measure cardiovascular hemodynamics and EVLWI for 7 days via an arterial cannula indwelled within 72 hours after diagnosis of severe sepsis was made, and serial bronchoalveolar lavages (BAL) were carried out.Other examinations including blood gas analysis,ventilator parameters,chest X-ray and the levels of pro-inflammatory cytokines such as tumor necrosis factor (TNF-oα),interleukin-1 in the BAL were recorded.In-hospital and ICU mortalities were also observed.Results Of total 40 patients,29 were complicated with clinically defined septic ALI/ARDS ( ARDS n =15,and ALI n =14).The septic patients complicated with ALL/ARDS had significantly higher amount of EVLWI and higher levels of TNF-α and interleukin-1 in the BAL than patients without ALI/ARDS ( P ＜ 0.05).The arterial oxygen tension/fractional inspired oxygen ratio,lung injury score,and the levels of TNF-α,IL-1 in the BAL correlated with EVLWI.Moreover,in-hospital mortality,ICU mortality and the length of ICU stay of the patients with high amount of EVLWI were markedly increased than those of patients with low amount of EVLWI. Conclusions In septic patients complicated with ALI/ARDS, the extravascular lung water index correlates with oxygenation,lung injury severity and inflammatory cytokines in lung.Determination of EVLWI may be useful for evaluation of severity of lung injury and prognosis of septic patients.

Objective To measure changes of definitive volume of rebuild CT image in three dimensional conformal radiotherapy (3DCRT) treatment planning system (TPS) under different scanning and observing conditions, which may provide a reference in selecting proper condition of scanning and observing, delineating target volume, and delivering treatment plan. Methods A self-made phantom was scanned under different CT scanning conditions, datas were imported to TPS, CT images were rebuilt in three dimensions under different observing conditions, and then the volumes of large, middle and small simulated tumors on CT images were compared with their real volumes. Results The volume defined by rebuilt CT imags in 3DCRT TPS varied according to different scanning and observing conditions. When scanning axial thickness was set at 10. 000 mm, errors of large, middle and small simulated tumor were - 13.60%, - 17. 68% and - 27. 53%, respectively. When 0. 625 mm was set, errors changed to -0. 50%, -0. 68% and -0. 81% ,respectively. When scanning pitch was set at 0. 562, 0. 938, 1. 375 and 1. 750, the errors were - 1.06%, - 1.09%, 5.52% and 4.75%, respectively. Extreme observing condition, window width and window level markedly increased errors of definitive volume of rebuilt CT images with a maximum of 80. 06%. Conclusions This study may provide clues in selecting scanning and observing condition, delineating target volume, and delivering treatment plan.

Objective To study the clinical efficacy of autologous peripheral blood stem cell transplantation for the treatment myocardial infarction,in the same period of coronary artery bypass grafting (CABG).Methods From January 2012 to January 2015,76 patients with myocardial infarction were selected.Patients were divided into transplantation group (n =46) and control group (n =30) on the basis of whether being treated by autologous peripheral blood stem cell transplantation.After myocardial infarction patients were taken to the hospital with the therapy of conventional drug,5 days before CABG,transplantation group was given the autologous peripheral blood stem cell mobilization and expansion,24 hours before CABG,taking autologous peripheral blood stem cell collection.76 patients took CABG with non-cardiopulmonary by pass,transplantation group was given autologous peripheral blood stem cell via transplantation vessels and subepicardial,while the control group was not given the injection of autologous peripheral blood stem cell.The LV morphology,wall motion score index (WMSI) and index of cardiac function before and after the operation in both groups were evaluated by echocardiography.Results Six months after CABG,there was a significant decrease in Left ventricular end-diastolic diameter and wall motion score index,Left ventricular ejection fraction was increased.The indexes of cardiac function in the transplantation group were better than the control group.Conclusion Autologous peripheral blood stem cell transplantation for the treatment myocardial infarction can improve the heart function,and has obvious recent clinical curative effect in the same period of CABG.

Objective To explore the clinical significance of blood flow reserve fraction in the treatment of coronary stent implantation.Methods A total of 46 patients with positive coronary angiography were included.Criteria for positive coronary angiography:coronary angiography confirmed at least a coronary artery stenosis was more than or equal to 50%.According to the results,the patients were divided into the control group(24 cases) and observation group(22 cases).Results 1.There was no significant difference in baseline level(P>0.05);2.The operation time,number of stents and the contrast agent dosage of the observation group were (63.20±9.92)min,(0.50±0.65) and (182.94±39.30)mL,which were significantly less than those of the control group,the differences were statistically significant(operation time t=2.69,P=0.01;number of stents t=2.56,P=0.02;contrast agent dosage t=6.98,P=0.00).There was no significant difference between the control group and the observation group in angina pectoris and MACE attack.Conclusion Blood flow reserve score is an important guiding parameter for PCI treatment of coronary artery stenosis.

Objective To investigate the correlation between interleukin 10(IL‐10) ,tumor necrosis factor (TNF‐α) and serum CD4+ T‐lymphocytes cell in people who infected HIV .Methods The HIV antibody screening test ,IL‐10 and TNF‐αmeasurement adopted enzyme‐linked immune‐sorbent assay(ELISA) .The HIV antibody confirm test adopted western blot(WB) and CD4+ cell count determination used flow cytometry .Results Compared with the normal control group(NC group) ,the concentration of TNF‐αand IL‐10 in patients group have statistically significant difference(P<0 .05) .Moreover ,the extent of the increase in group A(pa‐tients with the CD4+ T cell count less than 3 .5 × 105 cells/mL) was higher than that in group B(patients with the CD4+ T cell count no less than 3 .5 × 105 cells/mL) .Conclusion Due to the defect of the immune system ,the serum concentration of TNF‐αand IL‐10 in people infected with HIV would increased ,and the increase of the concentration could be more significant in patients whose CD4+cell count obviously decrease .This study have shown that dynamic measurement of TNF‐α and IL‐10 concentration would provide data to konw the patients′immune status and illness development .
