Objective To discuss the risk factors and nursing intervention of multidrug-resistant organism (MDRO) infection in patients of traditional Chinese medicine hospital (TCM). Methods By investigating the patients admitted to Beijing Xuan Wu Hospital of Traditional Chinese medicine from June 2015 to June 2016, 756 patients of them who were confirmed with clinical diagnosis of infection and pathogen detection with positive, which were divided into MDRO group including 97cases and non-MDRO group including 659 cases, then the pathogens of MRDO infection species and distributionwere counted, and analyzed risk factors for infection. Results A total of 756 cases were detected positive strains 816 strains, including 611 strains of monitoring target strains, 116 strains of MRDO. The top three were methicillin-resistant staphylococcus aurous 30.17%(35/116), Pseudomonas aeruginosa 18.97% (22/116) and Klebsiella pneumonia 18.10% (21/116). Single factor analysis results showed that the patients' age, hospitalization days, the history of other hospital admission, invasive procedure, basic chronic disease (diabetes, cerebrovascular disease, lung disease) and combined use of antibiotics were MDRO infection risk factors (χ2=9.470-198.609, P < 0.01); multivariate Logistic regression analysis showed that the independent risk factors of MDRO infection were the history of other hospital admission (OR=2.085, 95%CI1.040-4.179), invasive procedure (OR=3.063,95% CI1.526- 6.150), diabetes (OR=2.037,95% CI1.070- 3.877), cerebrovascular disease (OR=4.349,95%CI 2.035-9.293)and combined use of antibiotics (OR=18.723,95% CI9.202-38.094). Conclusions Patients of TCM have many characteristics, such as with more basic diseases, longer length of stay, elder and so on. So we should be alert to the risk of MDRO infection and take nursing interventions to prevent and strengthen the isolation prevention.

Objective 99Tcm-4,9-diaza-3,3,10,10-tetramethyldodecan-2,11-dione dioxime(HL91),a new type of hypoxic agents,accumulates in tumor hypoxic tissue specifically.The aim of this study was to evaluate the value of 99Tcm-HL91 imaging in the diagnosis of bone metastasis.Methods Nineteen cases with bone metastasis(without any treatment)and 8 cases with benign lesions underwent SPECT imaging at 4 h after injection of 740 MBq of 99Tcm-HL91 along with 99Tcm-methylene diphosphonic acid(MDP)imaging.Regions of interest(ROIs)were drawn in tumor tissue and contralateral normal tissue respectively,and the radioactivity ratios of tumor-to-normal(T/N)were calculated.The t-test was used for data analysis with SPSS 11.0.Results There were visible uptake of 99Tcm-HL91 in 79 out of 85 focuses in 19 patients of bone metastasis;however,there was no obvious uptake of 99Tcm-HL91 in 12 focuses of 8 patients of benign lesions.Significant difference existed between the T/N values of malignant(1.877±0.288)and benign lesions[(0.735±0.236);t=13.065,P＜0.05].However,the T/N value of bone metastasis from lung cancer did not differ with that from prostate cancer(1.915±0.344 and 1.825±0.175,respectively;t=1.378,P＞0.05).Conclusion The results indicated that 99Tcm-HL91 was useful in diagnosing the malignant and benign bone lesions.

Objective To evaluate the extra-anatomic bypass surgery for aorto-iliac occlusive disease in the elderly. Methods From January 2005 to December 2008,33 elderly patients/39 limbs (age ranged from 70 to 87 years, mean 76.0 ± 3.0 years) with aortoiliac occlusive disease were retrospectively analyzed. According to Fontaine classification, there were 5 phase Ⅱ b cases (7 limbs), 22 phase Ⅲ cases (26 limbs), and 6 phase Ⅳ cases (6 limbs), all cases were with TASC C, D lesions. Results These 33 cases/39 limbs were tr eated with a variety of bypass, including axillobifemoral bypass (6 cases/12 limbs) ,axillofemoral bypass ( 20 cases/20 limbs ), femorofemoral bypass ( 7 cases/7 limbs ). Intermittent claudication improved in 5 cases, rest pain disappeared in 22 cases, and ulcers healed in 6 cases after operations. The mean ABI increased from 0.29 ± 0.11 to 0.66 ± 0.13 ( t = 2.69, P ＜ 0.05 ). All limbs were salvaged and there was no perioperative mortality within 30 days after operations. Postoperative complication rate was 9.1%. Patients were followed up for a median of 12 ±5 months (range, 6 to 28 months), primary patency rate was 89.7% (35/39), secondary patency rate was 94.9% (37/39), limb salvage rate was 92.3% (36/39). After dischargement the mortality was 6.1% (2/33) with one dying of myocardial infarction and another one of malignant tumor (gastric cancer). Conclusions Extra-anatomic bypass for aorto-iliac occlusive disease in the elderly is feasible, safe and effective, and the cardiopulmonary dysfunctions are the major risk factors for perioperative complications.

Objective To discuss the strategies of prevention and treatment for complications of endovascular therapy in aortoiliac artery occlusive disease.Methods 220 cases who received endovascular interventions with aortoiliac artery occlusive disease were retrospectively reviewed from June 2012 to June 2014.Among these patients,189 cases were males.The age was between 46 to 85yrs and the average age was 64yrs.Results The overall technique success rate was 97.2％.Nine procedure-related major complications requiring additional endovascular or surgical treatment were encountered in 7 patients including 2 acute in-stent thrombosis,1 iliac artery rupture,1 distal embolism,and 5 puncture associated complications (2 acute artery thrombosis,1 arteriovenous fistula,1 hematoma,1 artery dissection).8 cases improved after second endovascular or remedial open surgery,among those 4 cases were managed by endovascular interventions including 2 catheter directed thrombolysis,1 cover-stent implantation and 1 balloon-based angioplasty,4 patients received open surgery including 3 thrombectomies,1 hematoma cleating.After 22 months follow-up,the primary patency,assistant-primary patency and secondary patency was respectively 90.8％,92.1％ and 99.2％.Conclusions More attentions should be paid to the complications of endovascular therapy in aortoiliac artery occlusive disease.Helpful to prevent these complications are a comprehensive evaluation of the lesions,and individualized surgical plan prior to the operations,and a careful intraoperative management.
