Journal of Interventional Radiology 2001;0(06):-
Objective To evaluate the role of heparin in treating thrombotic diseases by interventional radiology.Methods In order to perform general anticoagulation, heparin or small molecule heparin were used for patients with acute brain thrombosis in 22 cases, limb artery thrombosis in 18 cases, ilic and formal vein thrombosis in 200 cases, inferior vena cava thrombosis in 20 cases. All patients were treated by thrombolysis with UK, or placing filter in inferior vena cava simultaneously with heparin. Results Under general anticoagulation, the effects of thrombosis dissolution for artery were positive. After thrombolysis, heparin must be used to keep the vascular patency. The recanalization of iliac and formal veins was lower than that of artery. The effect of applying heparin combined with thrombolysis was better than that of thrombolysis alone. Conclusions During the course of therapy of thromobotic diseases application of heparin should be the first and their follow by thrombolysis that is the principle for interventional therapy.

The key to clinical paths administration lies in the optimization of the key processes and sectors in medical service, which will achieve an integration that is based on patients and span departments to cover all medical service sectors and processes. The clinical path practice was introduced into the hospital in 2005, and the clinical paths have been put into practice for over 20,000 cases/occasions by the end of 2009, scoring satisfactory social and economic outcomes as of now. For the purposes of speeding up the clinical path practice for expected outcomes in optimizing key medical service processes, we have got the following eight experiences and lessons: (1) Build shared demands; (2)Establish a powerful leadership; (3) Develop and promote visions; (4) Eliminate resistance and pool the forces; (5) Keep on the efforts and focus on details; (6) Reward involvements; (7) Recruit and develop key operators within the hospital; (8) Systemize and supervise the experiences of implementation.Promotion of clinical paths is a renovation in management with its inherent rules. Adoption of appropriate technical strategies and cultural strategies will upgrade the quality and acceptance of clinical path implementation.

Objective:To investigate the adherence of patients with chronic airway disease with inhalation therapy and to explore the influencing factors.Methods:A total of 180 outpatients with chronic airway disease were selected by convenient sampling. The general information, adherence of inhalation therapyquestionnaire, asthma knowledge questionnaire, chronic obstructive pulmonary disease (COPD) health literacy questionnaire (COPD-Q) were used to evaluate the general information, adherence of inhalation therapy and disease knowledge level of the patients. The severity of the disease was evaluated by asthma control test (ACT) score and COPD assessment test (CAT) score. ANOVA and t-test were used to analyze the adherence of patients with chronic airway disease, and multivariate linear regression was used to analyze the adherence. Results:The adherence score of asthma patients was 89.74 ± 7.27 and the adherence score of COPD patients was 86.80 ± 9.16, which were in the middle level. The risk factors of non-adherence of inhalation therapy were retirement, living alone and smoking. The effect of inhaled treatment time on the adherence of inhaled therapy is not linear, and the turning point of adherence decline occurs one year after the patients received inhaled therapy. The results of multiple linear regression showed that the effect of course and employment on the adherence of inhalation therapy was statistically significant.Conclusions:The adherence of chronic airway disease patients with inhalation therapy is not ideal, especially for the patients with long course, smoking, retirement and living alone, the medical staff should pay more attention, take appropriate intervention measures to improve the adherence of inhalation therapy.

Objective To observe the changes of haemodynamics and cerebral state index during double-lumen endobronchial intubation with glidescope ranger video laryngoscope (GSVL) and macintosh direct laryngoscope (MDLS). Methods Forty-eight ASA Ⅰ or Ⅱ patients aged 35 ~ 67 yrs were enrolled in this study, who were scheduled for elective pulmonary cancer or cancer of esophagus radical correction tients were random divided into 2 groups( n =24 each), GSVL group and MDLS group. After anesthesia was induced, all patients were given a score of Cormack grading under MDLS and GSVL, and then endobronchial intubation was performed. Noninvasive BP and HR were recorded before and after induction of anesthesia, during endobronchial intubation and after endobronchial intubation was completed for 1,2, 3, 4,5 min. The CSI was continuously monitored and recorded before and after induction of anesthesia, and after endobronchial intubation for 1 ~ 2 min and 3 ~ 5 min. Results Compared with MDLS group, the rate of Cormack grade 1 was significant higher in GSVL group (91% vs 58% ) ( P <0. 01 ). BP of two groups at T1 and T5 ~ T7 were significantly decreased compared to T0 values ( P <0. 01 ). Endobronchial intubation (T2 ~T4) caused significant increase in BP and HR compared to post-induction values(T1 ) ( P <0. 01).The highest values of HR after intubation exceeded even their baseline values before induction of anesthesia.The haemodynamic responses to endobronchial intubation in GSVL group at T2 ~ T4 were significantly different from those in MDLS group( P <0. 05). CSI of two groups at T1 was significantly decreased compared to To values( P <0. 01 ), CSI of two groups at T2 induced significant increase compared to T1 values, and the increase of CSI in MDLS group was stronger than that in GSVL group( P <0.01). Condusion The haemodynamic responses produced by orotracheal intubation using GSVL had more obvious advantages than MDLS, but GSVL seemed to provide a clear view of glottis and a little change CSI effect.

Objective To prepare the chitosan-potD nanoparticles and to evaluate its protective efficacy against pneumococcal nasopharyngeal colonization. Methods potD gene was amplificated from pneumococcal genome and was inserted into pVAX1 expression vectors to construct pVAX1-potD recombinant plasmid which was then transfected into 293T cell using LipofectAMINE 2000 to analyze transient potD gene expression in vitro by RT-PCR and Western blot. Chitosan-potD nanoparticles were freshly prepared by coacervation methods at each time and the characterizations of the nanoparticles were then evaluated. BALB/c mice were immunized with chitosan-potD, naked potD DNA or pVAX1 for 4 times at two-week intervals. Anti-PotD IgG, IgG1 and IgG2a levels in serum and IgA levels in nasal washes, bronchoalveolar lavage fluids (BALF) and middle ear lavages(MEL) were detected by indirect enzyme-linked immunosorbent assay (ELISA). IL-17A, IL-4 and IFN-γ levels in splenocytes were determined by double sandwich ELISA. Mice were intrannsally challenged with Streptococcus pneumoniae ATCC6303, and Pneumococci were recovered from the nasopharyngeal niche at the fifth day after challenge. Results potD gene was successfully amplificated by PCR and the sequence was confimed to be consistent with that in the Genbank. The pVAX1-potD recombinant plasmid was successfully constructed and was expressed in eukaryocytes in vitro. The mean size and zeta potential of chitosan-potD nanoparticles was 430 nm and + 20.5 mv, respectively. Chitosan-potD nanoparticles were not digested by DNase Ⅰ , while naked potD DNA was completely digested. The levels of antibodies inculding IgG, IgG1, IgG2a, IgA and cytokines including IL-17A, IL-4 and IFN-γ were significantly higher in mice immunized with chitosan-potD nanoparticles than mice with naked potD or pVAX1 ( P <0.05) only. More importantly, much less Pneumococci were recovered from mice immunized with chitosan-potD nanoparticles than the other groups(P <0.05). Conclusion Chitosan-potD nanoparticles significantly enhanced the immunogenicity and protection efficacy of DNA vaccines by intranasal immunization and could be used as a potential mucosal vaccine to prevent pneumococcal infection.

Objective To investigate the serum level of NT-pro-BNP in patients with acute ischemic stroke and to determine whether NT-pro-BNP levels were associated with the death within 15 days of stroke onset. Methods Two hundard twenty-six consecutive patients with acute ischemic stroke within 48 hours of onset were enrolled in this study. We measured plasma NT-pro-BNP within 72 h and recorded the NIHSS score on admission. Patients were divided into two groups: the deceased group, who died within 15 days, and the survival group. The factors associated with the death within 15 d of stroke onset were investigated by using multivariate logistic regression analysis. Results Twenty-four (10.6%) patients died with 15 days of stroke onset. The incidence of atrial fibrillation, cardioembolism and large infarc?tion, the mean ± SD of NIHSS score, age, glucose level and creatinine were significantly higher in the deceased group than in the survival group (P<0.001). On the other hand, the mean ± SD of LVEF, albumin, LDL-C, and total-cholester?ol were significantly lower in the deceased group than in the survival group(P<0.05 ). The median of the plasma NT-pro-BNP level was significantly higher in the deceased group than in the survival group (2598.5 vs. 190.4 pg/mL, P<0.001). The optimal cut-off level, sensitivity, specificity and ROC area of NT-pro-BNP levels to distinguish the de?ceased group from the survival group were 955.2 pg/mL, 83.3%and 82.2%, 0.906, respectively. Binary logistic regression analysis demonstrated that NIHSS score of ≥13 (OR=56.18, 95% CI=9.06 to 348.40, P =0.000) , plasma Lg NT-Pro-BNP level (OR=38.79, 95%CI=6.52 to 230.95, P=0.000) , and the size of infarction (OR=8.73, 95%CI=1.11~68.88, P=0.040) were independent factors associated with the death within acute phase of stroke. Conclusions The plas?ma NT-pro-BNP level can predict the death of stroke patients within 15 days of stroke onset.
