OBJECTIVE:To investigate the situation of drug use and occurrence of side effects of drug interactions in the inpatients with chronic obstructive pulmonary disease(COPD).METHODS:54 medical charts of the inpatients in the First Affiliated Hospital of Tsinghua University diagnosed as having COPD from Oct.2006 to Feb.2007 were randomly collected for analyses of patients' basic information drug utilization.RESULTS:The COPD patients received more than 8 kinds of drugs simultaneously in more then 20% of their hospital days.Side effects of drug interaction occurred in 70% of them.CONCLUSION:The study shows that the drug use in the COPD inpatients is characterized by excessive drug kinds and high incidences of drug interactions,therefore,it is urgent to take further intervention measures on drug use in COPD inpatients.

Objective Establishment of HPLC to determine the content of Baicalin in different processing varieties of traditional Chinese Medicine.Methods The HPLC method was used to determine the content of Baicalin in different processing varieties of Radix. The analytical column was thermo- C18 (150 mm × 4.6 mm, 5μm). The mobile phase consisted of methanol-water- phosphoric acid solution (47:53:0.2). The column temperature was 35℃,and the UV detection wavelenghth was 280 nm.Results The contents of Baicalin in different processed products were different. The lowest content of Radix. It was considered that the content of Baicalin in Radix decreased with the time of processing and the degree of heating.Conclusions It's known that the difference of baicalin content in different processed products ofscutellaria baicalensis Georgi was conducive tothe rational and scientific process of products.

Erythropoietin is a critical growth factor in development of erythrocyte. After binding to its receptor, eryhropoietin produces biological action through consequent activation of intracellular signal transduction systems, including JAK2-STAT5, sos-Ras-MAPK, IRS-2- PI 3-K + and Ca 2+ channel.

Objective To study the clinical nursing significance of ECG monitor in primary PCI for AMI patients and the relation of changes in ECG and the reperfusion of infarction related artery.Methods Regressional analysis was made in ECG changes including different types of arrthymia,degree of ST segment regression,and their relation between the reperfusion of infarction related artery before and after interventional therapy in AMI patients.Results In 468 AMI patients,142 patients had ventricular arrhythmia before therapy.After interrentional therapy,285 patients were co-morbid with accelerated ventricular tachycardia,203 patients with transient ventricular tachycardia or R-on-T phenomenon,62 patients with ventricular fibrillation and received asynchronous electriacal cardioversion.Twenty four patients had new onsent of Ⅱ-Ⅲ degree atrio-ventricular block and 45 patients had bradycardia or sinus arrest.The atrio-ventricular blook in 10 patients before PCI disappeared after the operation.There are 301 patients with apparent ST segment regression(ST segment regressed ≥50%,57 patients with partial ST segment regression,and 29 patients without ST segment changes.Conclusion Arrhythmias always accompanied with IRA reperfusion.Careful monitoring of ECG is essential for patients' safety after AMI.Obvious ST segment is observed in sufficient IRA reperfusion.However,poor regression of ST segment as well as haemodynamics disorder and cardiogenic shock is observed in patients with poor reperfusion or subacute occlusion of IRA.

Objective To investigate the concentrations of formaldehyde in newly decorated apartments. Methods In this study we monitored the concentrations of formaldehyde in indoor air of 28 newly decorated apartments and offices and furnishings. In order to analysis the correlation between formaldehyde concentration of indoor air and personal exposure level, 17 persons' exposure levels were measured by personal air monitoring in 2 offices. Results The medians of formaldehyde concentrations in indoor air and furnishings were 0.062 mg/m3 and 0.260 mg/m3 respectively. The concentration of formaldehyde in furniture was significantly higher than that in indoor air (Z=-5.098,P

Objective To investigate the MRI features of hepatic IgG4?related inflammatory pseudotumor (IPT). Methods Nine patients with 11 histopathologically proven IgG4?related hepatic IPTs were retrospectively analyzed. The clinical, morphological and MRI signal features on T1WI, T2WI, dynamic?enhanced, and diffusion?weighted imaging were assessed in detail and correlated with pathological findings. The paired t test was used to compare the ADC values of the tumors and the hepatic tissue. Results Hepatic IgG4?related IPT displayed certain MRI features. The dominant lesions were subcapsularly distributed (n=7) with a clear boundary (n=8), which typically showed hypointensity on T1WI (n=11), mild hyperintensity on T2WI (n=8), progressive (n=5) or persistent (n=4) enhancement pattern. Accompanied signs included delayed capsule?like enhancement (n=6) and central nonenhanced areas (n=7). Two lesions showed atypical wash?out pattern with iso or hypointensity on portal and delayed phases. In diffusion weighted imaging, all lesions were hyperintense, and the mean ADC value of the lesions [(1.42 ± 0.36) × 10?3mm2/s] was mildly lower than that of surrounding liver [(1.55±0.31)×10?3mm2/s], although no statistical differences were found(t=0.78, P=0.46). Conclusions Hepatic IgG4?related IPTs display various MRI manifestations. The lesions normally show progressive enhancement pattern with diffuse homogeneous or heterogeneous hyperintensity, accompanied by delayed capsule?like enhancement and central nonenhanced areas.

PurposeTo establish sensitive and reliable serum marker on liver fibrosis for early clinical diagnosis. MethodsSerum hyaluronate acid,type Ⅲ procollagen and type Ⅳ procogen of 48 patients with viral hepatitis were analyzed by radioimmunoassay and ELISA respectively. ResultsThe serum HA, PCⅢ and PCⅣ level increased gradually with the progress of the disease. Their levels were correlated distinctly with the index of hepatic activity of inflammation and that of fibrosis.ConclusionsThe value of serum HA,PCⅢ and PCⅣ in predicting liver fibrosis will be enhanced ff the effect of inflammation could be excluded.

Objective To research the chronic respiratory infectious diseases caused by Pseudomonas aeruginosa need to objectively the reflection of the real environment in the body, so established a mouse model of chronic pulmonary infection with Pseudomonas aeruginosa and analyzed it's inflammatory response. Methods Establishment of chronic bronchial infection mice model that were inoculated with Pseudomonos aeruginosa-laden agarose beads, and analyzed its inflammatory response by detected the cytokines and MMP-2, and a differential cell count and a total leukocytes count were performed as well. Results Pseudomonas aeruginosa had been detected after infection, and there were changes in pathological. Pulmonary inflammation appeared in 1 d and reached near baseline levels by 7 d after inoculation. It was verified that the peak of inflammatory reaction in Pseudomonas aeruginosa infection is in 2-3 d; the mice did have detectable levels of circulating matrix metalloproteinase-2 ( MMP-2 ) after infection with Pseudomonas aeruginosa. MMP-2 concentrations in the blood serum peaked at 3 d after inoculation. It is indicated that Pseudomonas aeruginosa can initiate a certain degree of pulmonary fibrosis on the basis of the pulmonary inflammation. Conclusion In this study, chronic bronchial infection animal model affected by Pseudomonas aeruginosa was established successfully. Base on this animal model, we can do the pathogenicity and drug resistance of Pseudomonas aeruginosa further study.

Purpose The glucosamine and chondroitin compound tablets were prepared. The anti-inflammatory and analgesic effects of glucosamine and chondrotin compound tablets were investigated. Methods The proportion of glucosamine and chondroitin was 5:4 to prepare compound tablets. The anti-inflammatory effect was investigated with carrageen-induced rats paw edema and cotton granuloma in rats. The analgesic effect was investigated using the pain models of mice which were induced by 0.6% acetic acid. Results Compared with control group the degree of paw edema in the low, middle and high dose group was decreased ( P < 0.05). Fourtreatment groups compared with control group respectively at the weight of granuloma were also markedly reduced ( P < 0.05) and the writhing number of mice induced by acetic acid was decreased ( P < 0.05 ) . Conclusion glucosamine and chondroitin compound tablets have anti-inflammatory effect and analgesic effect on models induced by acetic acid.
