Objective To investigate the effects of remote preconditioning on inflammatory cytokines and respiratory index of rabbit lung injured by ischemia/reperfusion.Methods Eighteen rabbits were randomly divided into three groups(6 each):control group(C),ischemia-reperfusion group(I/R)and remote preconditioning group(R).The plasma concentrations of interleukin-6(IL-6),tumor necrosis factor-?(TNF-?)and interleukin-10(IL-10)were measured before ischemia and 60,120 and 180 min after reperfusion.Respiratory index(A-aO2/PaO2)was calculated before ischemia and 15,30,60,120 and 180 min after reperfusion.The animals were sacrificed after reperfusion,and the left lung was removed for calculation of wet/dry(W/D)ratio and lung permeability index,histological examination was done with light microscope,and diffuse alveolar damage(DAD)scores was estimated.Results The plasma concentrations of IL-6 and TNF-? were significantly higher in I/R group than in C group(P

Objective To know automobile exhaust pollution and population exposure to automobile exhaust in Taiyuan,and to provide the basis for controlling automobile exhaust pollution.Methods Two different automobile pollution areas(A and B) were selected as the monitoring sites,the continue sampling was carried out for one week from March to April in 2008.The concentration of PM2.5 was determined by mass method,the inorganic elements in PM2.5 were extracted by Soxhlet method, arsenic and mercury were measured by atomic fluorescent spectrophotometer(AFS),the other metal elements were measured by atomic absorption spectrophotometer.The concentration of NO_x was detected by Saltzman method,the concentration of CO was measured by non-dispersive infrared absorption method.Results At crossroad A,daily average concentration of PM2.5 was 1.604 mg/m~3,which was significantly higher than that at crossroad B(0.64 rag/m~3),P

Objective To observe the effect of robot-assisted upper limb training on the recovery of upper limb motor function after stroke.Methods One hundred patients within one month of suffering a stroke were randomly divided into a control group (50 cases) and a therapy group (50 cases).Both groups were given conventional drug therapy and rehabilitation training,while the therapy group also received robot-assisted training once a day,5 days per week for 12 weeks.The Fugl-Meyer assessment for the upper extremities (FMA-UE),the modified Ashworth scale (MAS) and the modified Barthel index (MBI) were used to evaluate the subjects before the experiment and after 4,8 and 12 weeks of treatment.Results During the treatment,the average FMA-UE scores and the average MBI of both groups increased gradually.The treatment group's averages were significantly better than those of the control group at each time point,except that there was no significant difference in elbow and wrist MAS scores.Conclusion Upper limb robots can be used with acute stroke patients in a clinical setting,and they may be beneficial for improving upper limb function and ability in the activities of daily living.

Objective To evaluate the clinical value of the three-category classification of severe acute pancreatitis (SAP).Methods Clinical data of 337 traditional SAP patients,who were admitted to Peking Union Medical College Hospital (PUMCH)from January 2001 to December 2012,were retrospectively studied.These patients were classified into moderately severe acute pancreatitis (MSAP) and severe acute pancreatitis (SAP) according to the latest 2013 Atlanta Classification.SAP patients were further categorized as critical acute pancreatitis (CAP) and non-CAP.Disease severity,therapy and prognosis among three groups were compared.Results Among the total 337 traditional SAP patients,253 were classified as MSAP and 84 as SAP.In the group of SAP,40 patients were categorized as CAP and 44 as non-CAP.Compared with non-CAP patients,CAP patients had significantly higher mortality rate which was 70％ (28/40).Other results were all significantly higher in CAP group rather than non-CAP group,including ICU admission rate 77.5％(31/40),length of ICU stay (15.5 ± 20.6) days,Ranson,APACHE Ⅱ,BISAP,MCTSI,modified Marshall scores 4.6 ± 1.4,16.8 ± 5.8,3.0 ± 1.0,8.6 ± 1.7,and 7.4 ± 2.9,respectively (P ＜ 0.01 in each endpoint).These parameters of SAP group were also significantly higher than those of MSAP group (P ＜0.01).Conclusions Using the new three-category classification to distinguish traditional severe acute pancreatitis,namely MSAP,SAP,and CAP,can better reflect the severity of disease,predict outcome and guide clinical management.

Objective To observe the efficacy of multifactor intensive nursing intervention on chronic heart failure patients with outside hospital treatment,including self-management ability and related clinical indicators.Methods By application of prospective study,a total of 215 patients with chronic heart failure discharged from hospital were randomized into the usual care group (105 cases) and the intensive nursing intervention group (1 10 cases).Patients were followed up for 12 months,and 205 patients completed the follow-up.The usual care group only received conventional outpatient follow-up,the intensive intervention group patients received telephone counseling,more detailed clinical follow-up and regular health education.The intervention effect was compared between two groups.Results Compared with the usual care group,the passing rate of sodium/water limit and daily monitoring of weight was higher in the intensive intervention group.Left ventricular ejection fraction and six-minute walking test were better in the intensive intervention group,while the level of NT-pro-BNP was lower in the intensive intervention group.Compared with the usual care group,re-hospitalization rate and incidence of cardiovascular events were lower in the intensive intervention group.Conclusions Multifactor intensive nursing intervention is helpful on improving self-management ability,alleviate cardiac function,reduce re-hospitalization rate and incidence of cardiovascular events for chronic heart failure patients.

Objective To evaluate the significance of detecting plasma methylated Septin9 (SEPT9) alone and combined with fecal immunochemical test (FIT) in screening colorectal cancer (CRC) and adenoma.Methods From October 2014 to April 2015,outpatients received CRC and adenoma screening were enrolled.Colonscopy examination and pathological diagnosis were taken as gold standard.The sensitivity and specificity of plasma methylated SEPT9 and FIT in CRC and adenoma were calculated.The diagnostic value of combined examination was evaluated.Receiver operating characteristic (ROC) curve of SEPT9 in CRC diagnosis was drawn.Results A total of 300 outpatients were enrolled.Among them,CRC was detected in 45 patients (15.0％) and adenoma was detected in 68(22.7％) patients,including 37(12.3％) cases of advanced adenomas.The sensitivity of SEPT9 and FIT for CRC diagnosis was 80.0％ and 88.9％,and the specificity was 95.3 ％ and 54.1％,respectively.The area under concentration curve (AUC) of methylated SEPT9 in CRC diagnosis was 0.923.The sensitivity of SEPT9 and FIT in advanced adenoma diagnosis were 10.8％ and 62.2％,and the specificity were 83.3％ and 49.0％,respectively.The sensitivity of combined examination in CRC diagnosis was 97.8％ and the specificity was 52.9％;the sensitivity in advanced adenoma diagnosis was 67.6％ and the specificity was 47.4％.Conclusions Plasma methylated SEPT9 is helpful in CRC screening,moreover,when combined with FIT,it can increase detection rate of colorectal adenoma.

Aim To investigate the effect of probucol on reverse cholesterol transport from macrophage to feces in vivo,serum lipid profiles of mice were tested before and after probucol administration for 4 weeks,and the 3H-contents in serum,liver and feces in mice were quantitated after 24 hours intraperitoneally injected macrophages which were labeled with 3H cholesterol.Methods 32 C57BL/6 mice were treated with different probucol(0,0.1%,0.5%,1% W/W)in chow diet for 4 weeks,then these mice were injected intraperitoneally with RAW264.7 macrophages(0.5 ml?mice,cells 5.0?106 with 6.2?106 cpm)which were loaded with cholesterol by incubation with acetylated LDL,labeled with 3H-cholesterol.Serum profiles were quantitated by enzymatic method;serum and liver tissues were harvested at 24th hour,feces were collected(0~24 hs),and all were analyzed for tracer counts(all were expressed as the percentage of the total injected counts per minute).Results After 4 weeks 0.1% probucol administration,the levels of total cholesterol(TC),high-density lipoprotein cholesterol(HDL-C)decreased markedly by 34.3%,52.8%,(P
