Objective To explore the clinical application of anticoagulation therapy for patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD).Methods 55 patients with AECOPD were selected and divided into control group(24 cases) and treatment group(31 cases).Oxygen treatment,anti-infection treatment were applied to the patients of the control group.Treatment group was given anticoagulation treatment with heparin at the base treatment of the control group.The treatment efficacy,pulmonary functions,coagulation functions and inflammatory factors were tested and compared.Results There were no significant differences between two groups of total treatment efficacy(80.65％ vs 79.17％,x2 =1.304,P ＞0.05) ;PaCO2 decreased,pH and PaO2 increased significantly after treatments in the two groups(all P ＜ 0.05),which was more significantly in the treatment group (all P ＜0.05) ;FVC,FEV1 and FEV1/ FVC％ increased significantly after treatments in the two groups(all P ＜ 0.05),more significantly in the treatment group (all P ＜ 0.05) ; APTT,PT were prolonged,the level of DD and PAD decreased significantly after treatments in the two groups(all P ＜ 0.05),which was more significantly in the treatment group(all P ＜ 0.05) ;The level of IL-6,IL-10 and hs-CRP decreased significantly in all patients(all P ＜ 0.05),IL-6and hs-CRP were more significantly in the treatment group (all P ＜ 0.05),but the level of IL-10 of the treatment group was higher than that of the control group (P ＜ 0.05).Conclusion Pulmonary functions,Blood-gas indexes could be improved,inflammatory balance and coagulation status could be maintained by anti-coagulation treatment in patients with AECOPD.

Objective:To prepare levofloxacin-carboxymethyl-chitosan(LVFX/CMC) microspheres and to study their colon-targeted release in rats.Methods: KromasilRKR100-5C18(250 mm?4.6 mm)was used as the analytical column and the temperature was maintained at 50℃.The mobile phase consisted of a mixture of acetonitrile:0.1% trifluoroacetic acid(2080) pumped at a flow rate of 1.0 ml/min,with ?_(ex)295 nm and ?_(em)495 nm.Sixty healthy male SD rats were randomized into 2 groups: to receive gastric lavage with normal LVFX(40 mg,control group) and LVFX/CMC microspheres(40 mg,treatment group).HPLC was used to detect the concentrations of LVFX in the stomach,intestine,cecum,colon and blood in rats in both groups.Results: LVFX was detectable 3 h after LVFX/CMC microsphere lavage.Five hours after lavage,the levels of LVFX in cecum and colon were respectively(3.394?0.197) mg and(1.873?0.216) mg in treatment group,and(0.489?0.123) mg and((0.078?0.002)) mg in control group(P

Objective To compare of treatment effects of intravenous iron and oral iron on hemodialysis ane- mia in patients with erythropoietin.Methods The oral dosage of ferrous succinate was 200mg dose,3 times a day for 2 months.After washing out for 2 months.Then these patients were given intravenous iron dextran with a dosage of 100mg twice a week for 5 weeks.During the treatment,hemoglobin (Hb),hematocrit (Hct),serum ferritin (SF) and trasferrin saturation(TSAT) were monitored.Results The efficacy of oral iron was 20 % ,the efficacy of intra- venous iron was 60 %.The Hb,Hct,SF and TSATS level increased obviously in the efficacy of intravenous iron,sta- tistical analysis showed a very significant difference(P

OBJECTIVE:To provide the pharmacoeconomics referance for the medical reform implementation in China.METHODS:The relevant literatures at home and abroad combined with knowledge of pharmacoeconomics were to introduce and analyze the experience of pharmacoeconomics application at home and abroad.RESULTS & CONCLUSION:The pharmacoeconomics is involved in various related areas of drugs,and provides a scientific basis for drug pricing,reimbursement and other links.China should be based on international experience,combined with its national conditions to promote the development of pharmacoeconomics in order to effectively control the unreasonable increase in drug expenses,so that people really can "control it,use it,and afford it".

OBJECTIVE:To evaluate the cost-effectiveness of salmeterol/fluticasone compound(SFC)and budesonide(BUD)in the treatment of asthma.METHODS:A multicenter randomized controlled clinical trial was performed on386asthma cases,who were administered with SFC50/100?g bid or BUD400?g bid,data on which were retrospectively collected and then the cost-effectiveness analysis was conducted,the effectiveness was measured in terms of successfully-treated weeks,symptom-free days and uninvolved days;The direct healthcare cost was adopted as the cost index.RESULTS:The average daily medical cost of the SFC treatment group(RMB:15.6yuan)was a little bit higher than that of the BUD control group(RMB:13.8yuan),but the costs of every successfully-treated week,every symptom-free day and every uninvolved day for SFC group were166.5yuan,33.4yuan and41.2yuan,respectively,which were all lower than those of the BUD group(which were188.6yuan,50.6yuan and66.1yuan,respectively);Incremental cost-effectiveness ratios for every successful?ly-treated week,per symptom-free day and per uninvolved day for the SFC group were88.7yuan,9.4yuan and10.8yuan,respectively vs.the BUD group.CONCLUSION:The results show that the cost-effectiveness of SFC50/100?g bid is supe?rior to BUD400?g bid in the treatment of asthma.

Objective To study the possibility and effect of application of clinical pathways (CP) in patients with lumbar vertebrae protrusion undergoing resection of nucleus pulposus. Methods 280 patients with lumbar vertebrae protrusion undergoing resection of nucleus pulposus were selected and divided into the experimental group and the control group randomly. Each group had 140 cases. Clinical pathways was applied to the experimental group, while traditional nursing method was given to the control group. Treatment and nursing effect were compared between the two groups. Results The cost for hospitalization was lower, hospitalization time was shorter, the first time for functional exercise after operation was advanced and satisfaction degree of patients was increased in the experimental group compared with those of the control group. Conclusions Application of clinical pathway in patients with lumbar vertebrae protrusion undergoing resection of nucleus pulposus played a positive and effective role.

To introduce the academic thoughts of traditional Chinese medicine(TCM)master GUO Zi-guang based on the analysis of clinical cases.His main academic thoughts are:①He proposes the theory of six meridians and their differentiation in the diagnosis and treatment of typhoid.The six meridians are bases for the treatment of all diseases,and their differentiation provides a fundamental principle for the differentiation of diseases.②He uses the method of combining the disease and syndrome in diagnosis and treatment,which widens the horizon of traditional differentiation and diagnosis in TCM and avoids the absence of syndrome in the practice of differentiation.In this way,the therapeutic effects of Chinese medicine can be guaranteed so as to meet the needs of medical and social development.③He emphasizes that it is fundamental to improve the therapeutic effects of TCM for its development.The approach is to combine disease and syndrome in diagnosis and treatment,and the way is to apply different methods in disease treatment.

Objective:To assess the anatomy of portal vein and hepatic vein with three dimensional 16-MSCT angiography.Methods:A total of 100 healthy subjects underwent upper abdominal MSCT examinations in our department.All subjects were administered 90～120ml of IV contrast material at an injection rate of 3ml/s.The scan delay time was 45～60s and 90～120s for portal venous and hepatic venous phase with automated bolus tracking,respectively.All data sets were reconstructed in 1-mm section and 0.5mm interval,and then were transferred to a workstation for maximum intensity projection(MIP)and volume ren-dering(VR) econstruction.The portal vein anatomy was classified according to Couinaud and Atri’s classification;the hepatic veinanatomy according to Nakamura’s,Marcos’s and Kawasaki’s classification.Results:① Normal portal vein anatomy was seen in 76 cases,type Ⅱin 16,type Ⅲ in 6,type Ⅳ in 2.②Nakamura’s TypeⅠof hepatic vein was presented in 72 cases;type Ⅱ in 22.type Ⅲ in 6.The branching pattern of the middle hepatic vein was type Ⅰin 65 cases,type Ⅱin 19,and type Ⅲ in 16.Segment IVb vein branched from the middle hepatic vein in 42 cases,and from the left hepatic vein in 58.Conclusion:3D 16-MSCTA is a significantly valuable tool which can provide complete and comprehensive information on the anatomy of portal vein and hepatic vein combined with MIP and VR image.
