OBJECTIVE:To evaluate the role of PDCA cycle management on standardizing clinical use of atomization inhala-tion drug. METHODS:Using a retrospective method,300 medical records of atomization inhalation drug use were collected from our hospital during Jan.-Dec. in 2013(non-intervention group),200 medical records collected during Apr.-Jun. in 2014(one cycle intervention group),and 180 medical records collected during Oct.-Dec. in 2014(two rounds of cycle intervention group). The use of atomization inhalation drugs was compared before and after the application of PDCA cycle management. Before and after two cy-cle intervention,4 types of medical staff were investigated on cognition of the related knowledge of atomization inhalation drugs, as physicians,pharmacists,nurses and mechanic. RESULTS:After two rounds of PDCA cycle management and intervention,the proportion of unsuitable route of administration of antibiotics,long acting glucocorticoid,non-atomization inhalation dosage form of resolving phlegm drugs,protease decreased from 54.0%,62.0%,59.7%,44.7% before intervention to 0.6%,1.1%,15.0%, 1.1% after intervention;those phenomena had not been found,such as unsuitable route of administration of TCM injection and non-atomization dosage form of theophyllines,unsuitable atomization frequence,unsuitable indication,drug mixture for preventing and controlling symptom,etc. The proportion of medical staffs being familiar with medical device,drug classification,drug selec-tion for prerention and treatment and the proportion of hospital drug stock to 93.4%,86.7%,92.4%,96.2% after intervention from 38.0%,79.0%,49.0%,39.5%before intervention. CONCLUSIONS:The application of PDCA cycle management can effec-tively regulate the use of atomization inhalation drugs in our hospital;the method can be promoted and applied.

Objective To evaluate immunogenicity of the recombinant protein GST-p55/570 of Pneumocystis carinii.Methods The fusion protein GST-p55/570 was expressed from the prokaryotic expression plasmid pGEX-570,and purified by using glutathione-agarose.The expressed product was analyzed by SDS-PAGE.Thirty-three mice were randomly divided into three groups,immunized with GST-p55/570,GST and PBS,respectively.Each group was immunized for four times at 2 week intervals.At the 7th day after final immunization,spleen was removed to obtain single cell suspension.Proliferation ability of lymphocytes was determined by MTT.Serum samples were collected at pre-immunizaton and two weeks after each immunization.Antibody level in sera of mice was determined by ELISA.The immune response to the recombinant GST-p55/570 recognized by sera of immunized mice was examined by Western blotting.Results The expressed fusion protein GST-p55/570 showed a Mr 47 000.Compared with GST group(1.134 5?0.073 5) or PBS group(1.124 8?0.041 6),a higher stimulation index(2.063 0?0.160 2) was revealed in GST-p55/570-immunized mice(P

Objective The research aimed to identify symptom clusters of head and neck cancer (HNC) patients.Methods The M.D.Anderson Symptom Inventory-Head & Neck (MDASI-H&N) was applied to measure symptoms of 247 HNC inpatients.Factor analysis was applied to identify symptom clusters.The Spearman correlation analysis was used to find the relationship of symptoms within symptom clusters.Results Five clusters were identified and the Cronbach's α coefficients of symptom clusters were 0.904,0.928,0.898,0.815 and 0.662 respectively.Symptoms within clusters were all significantly interrelated to each other (r=0.393-0.856,P＜0.01).Conclusions Symptoms of HNC patients tend to occur not in isolation,but in symptom clusters.Effective management can not only eliminate or alleviate the symptom burden of HNC patients,but also be cost-effective.

Objective To explore the bioeffect of different parameters on 4 cell lines by ultrasoundmediated microbubble destruction.Methods The orthogonal experimental design was used to investigate the effect of three factors on the bioeffects of four cell lines under three levels.Three factors included microbubble concentration,sound intensity,irradiation time.Human breast tumor (MCF-7) cells,ovarian tumor (A2780) cells,liver tumor (Bel7402) cells and thyroid tumor (ARO) cells were exposed to ultrasound in the presence of SonoVue.The cell survival rate was determined by MTT methods and the cell luminosity factor was detected by flow cytometry.Results The optimum parameters for Bel7402 and ARO cell were the same (A2B3C2),and they were different from those from MCF-7 (A3B1C1) and A2780 (A1B3C3) cell.The cell survival rates for 4 cell lines were above 75％,and the cell luminosity factors were different among 4 cell lines.Conclusions The optimum parameters by ultrasound-mediated microbubble destruction for different cell lines are different,and under the optimum parameters the bioeffects of different cell lines are different.

were measured at the end of inspiratory.ResultsThe differences of following parameters were statistically significant between the healthy control group, mild PH group, moderate PH group and severe PH group: velocity time integral of ventricular systolic wave (SVTI), velocity time integral of ventricular diastolic wave (DVTI), AR, AR/S, ARVTI/SVTI, AR/(S+D), ARVTI/(SVTI+DVTI,F=2.940, 2.838, 3.373, 7.681, 3.478, 12.052, 4.806;P<0.05,<0.05,<0.05,<0.01,<0.05,<0.01,<0.01). Correlation analysis showed that ratio of AR/(S+D) was positively correlated with pulmonary artery mean pressure (r= 0.575,P<0.01). ConclusionsThe ratio of AR/(S+D) of MHV Doppler flow spectra was correlated with pulmonary artery mean pressure. The ratio increased along with the increasing of pulmonary pressure in CHD patient. The Doppler echocardiographic detection of MHV flow had a certain reference value for the diagnosis of PH. The ratio of AR/(S+D) could be a new non-invasive parameter for evaluating PH.

To investigate the protective effect of the seed oil of Abelmoschus esculentus on gastric ulcer,two acute gastric ulcer mice models were established by intragastric administration of aspirin or absolute ethanol,respectively.Clinical index of ulcer area,ulcer index,gastric volume,gastric pH value,free acidity,total acidity,and histopathological assessment were measured to evaluate the injuries of gastric ulcer and the protective effect of okra seed oil In order to comprehensively uncover the possible underlying mechanism,a series of biochemical assays were also performed,including serum TNF-α,IL-6,IL-10 and Tbil,NO,MPO and SOD in the stomach included.Moreover,the ALT,AST and ALP in the liver of mice were also tested to evaluate the possible hepatic toxicity of the seed oil.The results indicated that the seed oil of A.esculentus exerted protective effect in ethanol-induced gastric ulcer mice by reducing the ulcer area and ulcer index,declining the free and total acidity,and increasing the pH value of gastric content.Histopathological observation showed the gastric mucosa of the acute gastric ulcer mice induced by alcohol was incomplete and severely damaged,with submucosal edema and nuclear pyknosis,as well as glandular structure disappearing,compared with that of normal mice.What's more,a number of inflammatory cell infiltration occured in the gastric mucosa of alcohol-model mice,with messes of neutrophils,lymphocytes,eosinophils and plasma cells.Okra seed oil could improve the damaged structure of the gastric mucosa and gland caused by ethanol,but could not ameliorate the condensation of nucleus and infiltration of inflammatory cells.Biochemical analysis revealed that the seed oil of A.esculentus could counteract the damage induced by ethanol via decreasing Tbil and TNF-α in serum,decreasing NO and myeloperoxidase,and increasing SOD in stomach.Meanwhile,okra seed oil exhibited protective effect in aspirin-induced gastric ulcer mice by increasing the gastric content pH,and reducing free and total acidity.Compared with the control group,the gastric mucosa of aspirin-model group showed multifocal coagulation necrosis,sheet edema and infiltration of inflammatory cells by histopathological assessment.Compared with the aspirin-model group,the soybean oil group and okra seed oil group could ameliorate the inflammatory cell infiltration.Biochemical analysis revealed that okra seed oil could counteract the injury induced by aspirin via decreasing TNF-α and IL-6,and increasing IL-1O in serum,decreasing NO and MPO and increasing SOD in stomach.In a word,the okra seed oil exerted protective effect on acute gastric ulcer by anti-inflammation,anti-oxidation and hepatocyte protection.The okra seed oil deserves further development and utilization.

Objective To analyze the changes of superior vena cava SVC spectra in patients with pulmonary hypertension PH and screen the proper parameters of SVC to predict PH Methods Eighty patients with congenital heart disease who underwent right heart catheterization for the measurement of pulmonary artery pressure were included SVC Doppler ultrasound was performed before the catheterization The cut-off point of SVC parameters in the prediction of PH was analyzed using receiver operator characteristic curve ROC curve Results Eighty subjects were included and there were 61 patients in PH group and 10 patients in the control group whose spectra pattern had four waves The data of the 9 subjects whose SVC spectrum were not four waves were excluded from the analysis Diagnostic criteria for PH was pulmonary artery systolic pressure PASP more than 30 mmHg measured by right heart catheterization The analysis of the peak velocity of SVC waves showed that ventricular systolic wave S reduced ventricular reversal wave VR reduced and the ratio of atrial reversal wave and ventricular systolic wave AR S increased in the PH group Compared with the control group their differences were statistically significant t =2 244 2 063 -2 896 P =0 028 0 043 0 005 The ROC curve showed that the ratio of AR S had better diagnostic effect than other parameters On the ROC curve of AR S when the ratio of AR S was 0 45 the sensitivity was 73 77% and specificity was 80 00% respectively for predicting PH When AR S was used to distinguish the control group from patients with moderate and severe PH group the sensitivity was 82 86% and specificity was 80 00% respectively Conclusions Using the ratio of AR S 0 45 as a cut-off for prediction of PH shows a good sensitivity and specificity which might be an alternative method for assessing PH
alternative method for assessing PH.

Purpose The mean pulmonary artery (MPAP) has been widely used as an important parameter to diagnose and evaluate pulmonary hypertension (PH).The purpose of this paper is to compare the efficacy of two methods in evaluating PH,including estimating pulmonary artery systolic pressure (PASP) using Doppler ultrasonography to measure tricuspid regurgitation (TR) velocity,and directly using the peak velocity of TR.Materiasl and Methods From January 2012 to June 2013,eighty patients with left-to-right shunt congenital heart diseases (CHD) planned for closure procedure in Tangdu Hospital of the Fourth Military Medical University and the General Hospital of Shenyang Military region were included in this prospective study,who underwent right heart catheterization to measure pulmonary artery pressure,and underwent Doppler ultrasonography to measure the peak velocity ofTR.Results Using catheter-measured MPAP of≥ 25 mmHg as diagnostic reference,the false positive rate was 62.96％,and the false negative rate 0％ when the estimated PASP of ＞30 mmHg determined by TR method was used to diagnose PH.There was high diagnostic agreement when peak velocity of TR was used to diagnose PH.When 320 cm/s and 340 crn/s were used as diagnostic cutoff values,false positive rates were 14.81％ and 7.41％,and false negative rates were 15.91％ and 20.45％,respectively.Conclusion In patients with left-to-right shunt CHD,peak velocity of TR measured on echocardiography can be used to diagnose PH which overcomes the high false positive rate in estimation method.It is more suitable to diagnose PH when the MPAP is used as the diagnostic criterion.

To construct the eukaryotic expression plasmid containing the p55 gene fragment of Pneumocystis and to investigate the efficient expression in COS-7 cells, the gene fragment conaining the whole length of p55 gene was used as template to amplify this fragment with PCR and the amplified fragment was then cloned to vector pGEM-T. After enzyme digestion, p55 gene was cloned to the eukaryotic expression vector pcDNA3.1(+) to construct the plasmid pcDNA3.1(+)-582. This plasmid was then transfected to the eukaryotic expression cells COS-7 and PCR and SDS-PAGE assays were used to confirm the presence of target protein in these cells. In these ways, the eukaryotic expression vector for the p55 gene of Pneumocystis of rats was successfully constructed and expressed in COS-7 cells, thus providing the basis for further studies on the nucleic acid vaccine.
