Objective To explore the application value of DOSE index score in the peitients with chronic obstructive pulmonary disease.Methods 122 cases of plateau COPD patients were followed up for 12 months,and we recorded and analyzed the patient's health and life.We also recorde FEV 1 and DOSE scores of the patients with COPD,and record the COPD risk events,including the number of respiratory failure and death,and the times of hospitalization,total such confinement,outpatient expenses,hospitalization expenses,mMRC,and scored in the number of exacerbations,etc.Results The DOSE index score was negatively correlated with FEV1％ pred (r=0.73,P ＜ 0.05) for 122 COPD patients,and were positively correlated with mMRC (r=085,P ＜ 0.01),the annual number of exacerbations (r=0.71,P ＜ 0.01),respiratory failure (r=0.65,P ＜ 0.01),heart failure (r=0.50,P ＜ 0.01),number of outpatient service (r=0.12,P＜0.01),hospitalization time (r=0.70,P＜0.01),the totalsuchconfinement (r=0.66,P＜0.01),outpatient expenses (r=0.13,P＞ 0.13),hospitalization expenses (r=0.65,P＜0.01).ROC curve was used to analyzed the cut-off point and curve area of COPD DOSE index.Conclusion The DOSE index is a simple COPD assessment tools,and is closely related to the prognosis of patients and health.

The digital X-ray imaging device was disinfected with trichloro-isocyanuric acid solution.The samples were taken with cotton swab pouring method before and 1,2,3 and 6 h after disinfection and the bacteriological examination was performed.Before disinfection the colony count of samples was all above the standard (＞ 10 cfu/cm2) with bacilli and gram-positive cocci predominantly.The highest count was detected in the X-ray photographic bed (58 cfu/cm2) and the lowest was in the exposure button(19 cfu/cm2).After disinfection the colony count in radiation suits still exceeded the standard,the colony count in diagnosis bed 2 h after disinfection,that in all parts of device 3 h after disinfection was off levels.The results indicate that the chlorine disinfectants can only achieve short-term effect in disinfection of digital X-ray imaging device.

Background Investigating the association of blue light-induced damage of retinal pigmenepithelial (RPE) cellwith intracellulaCa2+ conteniimportanfounderstanding the mechanism of retinal disorders.Objective Thistudy wato establish blue light-induced damage model of human RPE celland explore the relationship between the damage of RPE cell and intracellulaCa2+ content.MethodHuman RPE cellwere cultured and passaged.Cell vitality waassayed by trypan blue staining.Fourth-generation cellwere used in these experiments.The cellwere exposed to blue lighwith an intensity of (2000±500)lx fo3,6,9 o12 hours,and the rate of apoptosiwaassayed by TUNEL to assesthe optimal irradiation time focellcultured.The cellwere then randomized into the withouirradiation group,irradiation only group,nifedipine group,ligh+ nifedipine group,(-) BayK8644 group and ligh+ (-) BayK8644 group.The laseconfocal microscope waused to determine the fluorescence intensity of intracellulafree Ca2+ aan excitation wavelength of 488 nm and an emission wavelength of 505 nm.The cell imagewere analyzed using computesoftware.The differenceof fluorescence intensity among the differengroupwere compared by one-way analysiof variance.ResultTrypan blue staining showed thathe viability of RPE cellwamore than 90％ afteculturing and passaging.No apoptoticell waseen aftelighexposure fo3 hours.However,differennumberof apoptoticellappeared aftelighexposure fo6,9 and 12 hours.The fluorescence intensity of intracellulafree Ca2+ in the nifedipine group wasignificantly lowethan thaof the withouirradiation group othe ligh+ nifedipine group(both aP=0.000).Lasescanning confocal microscopy showed thathe fluorescence intensitieof intracellulafree Ca2+ in the irradiation only group,(-) BayK8644 group,ligh+ (-)BayK8644 group were highethan thaof the withouirradiation group,with statistical significancebetween them(all P=0.000).No significandifferencewere found in the fluorescence intensity of intracellulafree Ca2+ between the ligh+ nifedipine group and withouirradiation group awell abetween the (-)BayK8644 group and the ligh+(-) BayK8644 group(P =0.339,P =0.410).ConclusionThe optical conditionfoblue light-induced RPE cell damage were exposure of blue-ligha(2000± 500) lx fo6 hourand culturing the cellfo24 hours.Blue lighexposure can induce damage of human RPE cellprobably by triggering the increase of intracellulafree Ca2+ concentration.

According to the requirement of simulated actual combat,based on the traditional contents of sanitary reconnaissance of water source,this paper introduced some practical knowledge and skills in drinking water under emergency,including water source search,utilization,drinking principles and some measures to reduce the loss of body water.These practices enriched and consum- mated the subject of sanitary reconnaissance of water source.

ObjectiveTo observe the effect of Xiaoyao powder combined with prozac and psychological therapy on post-stroke depression (PSD).Methods85 PSD patients were randomly divided into the treatment group (n=43) and control group (n=42). All patients were treated with routine therapy, including prozac and psychological therapy. Patients in the treatment group were also given Xiaoyao powder. Scores of Hamilton Depression Scale (HAMD), modified Barthel index (MBI) and Scandinavian Stroke Scale (SSS) of all patients were evaluated before and after therapy.ResultsAfter treatment, the effective rate and MBI scores were significantly higher and scores of HAMD and SSS were significantly lower for patients of the treatment group compared with those of the control group (P<0.01).ConclusionXiaoyao powder combined with prozac and psychological therapy can improve depression and neural function of PSD patients significantly.

AIM: To observe the changes of MMP-9 expression in rabbit retina after laser irradiation at different thresholds of 577nm.METHODS: Twenty-six pigmentation rabbits were randomly divided into normal control group(n=2), conventional photocoagulation group (n=6) and subliminal micropulse laser photocoagulation group (n=18).The conventional photocoagulation group was treated with 577nm laser photocoagulation, subcutaneous micro-pulsed laser photocoagulation at a working loading rate of 9%, 12% and 15%, respectively.Eighteen rabbits were again divided into three subgroups according different powers of subthreshold working loading rate of 9%(n=6), 12%(n=6) and 15%(n=6) that undertook, respectively.The expression of MMP-9 on the retina of rabbit eyes was detected by immunohistochemistry.RESULTS: In the conventional photocoagulation group, the expression of MMP-9 in the RPE layer and the visual cell layer was strongly positive, which was significantly higher than that in the sub-micro pulse group(P<0.05).Less MMP-9 positive expression of RPE layer and visual cell layer in the working loading rate of 9% subgroup, and more MMP-9 positive expression of RPE layer and visual cell layer in the working loading rate of 12% subgroup;little expression was also noted in the nucleus of RPE and visual cell layer.Moderate MMP-9 positive expression of RPE layer and visual cell layer was observed in the working loading rate of 15% subgroup.There were no significant differences between the three subgroups (P>0.05).CONCLUSION: The 577nm subliminal micro-pulsed photocoagulation has high selectivity to retinal pigment epithelium at working load rate of 9%, 12% and 15%, and no damage to retinal nerve fiber layer, which is safer than conventional 577nm laser photocoagulation.
