目的 探讨末梢灌注指数（TPI）在断指再植术后对血管危象早期诊断的价值。 方法 对2005年1月－2011年10月31例36个再植指运用Agilent V24C监护仪血氧饱和度探头进行持续TPI监测，同时观察记录术后再植指皮温、色泽、肿胀程度及毛细血管搏动情况，将发生血管危象的再植指分为危象组（n=4），将未发生血管危象的再植指分为对照组（n=32），分析发生危象前12 h至危象发生时的TPI，每2小时为一时间段，共7个时相，分别记为T1~T7。 结果 对照组各时间点TPI无明显变化，各时间点比较差异无统计学意义（P＞0.05）；危象组从T4开始，TPI呈逐渐下降趋势，与前一时间点比较差异均有统计学意义（P＜0.05）。两组TPI在T1、T2、T3时比较差异无统计学意义（P＜0.05）；从T4开始，危象组TPI均较对照组降低，差异有统计学意义（P＜0.05）。 结论 TPI监测能够无创、实时、灵敏地反映断指再植术后再植指血供情况，可早于临床症状以前对断指再植术后血管危象作出诊断，有较高的临床应用价值。
Objective To explore the experience and needs of orthopedic inpatients for pre-hospital examinations led by nurses, provide a reference for optimizing the pre-hospital examination procedures and improve the pre-hospital examination experience of patient. Methods Using the method of phenomenology, semi-structured in-depth interviews were conducted on 35 patients who attended the Department of Orthopedics of the Second Affiliated Hospital of Army Medical University from July to August 2018 and had undergone pre-hospital examinations. Colaizzi’s seven-step method was used to encode, analyze, organize, summarize, and refine topics. Results Patients’ experience and needs for pre-hospital examinations led by nurses could be divided into three major sections: attitudes and emotions, individualized pre-rehabilitation needs and pre-hospital examination feelings. Attitudes and emotions included high treatment expectations, feelings of loss, and some patients’ understanding of pre-hospital examinations. Individualized pre-rehabilitation needs included pre-rehabilitation needs with cardiopulmonary diseases, pre-rehabilitation needs with sleep dysfunction, nutritional conditioning needs, and medication safety needs. Patients’ feelings during pre-hospital examinations mainly included complicated procedures and staff attitudes that need to be improved. Conclusion Some links in the pre-hospital inspection process urgently need to be optimized. In pre-hospital examinations, it is necessary to focus on patient expectation management and predictive communication, improve multidisciplinary cooperation, formulate personalized pre-rehabilitation plans, optimize examination procedures, strengthen humanistic care, and improve patient experience.
Objective To explore the effect of self-assessment of pain in perioperative pain management of total knee arthroplasty (TKA). Methods A total of 140 patients undergoing TKA from March 2016 to March 2017 were randomly divided into the control group and the trial group. The patients in the two groups were received the same education relating to pain knowledge. The intensity of pain was assessed by nurses in the control group, while in the trial group, it was assessed by patients themselves. According to the assessment of pain, treatments were given to both groups. Time of pain assessment, types and frequencies of temporary rescue medicine, pain intensity, the score of Self-efficacy for Rehabilitation Outcome Scale (SER) and the range of motion (ROM) of knee were observed and recorded. Results There were 132 patients who completed the final observation, with 67 in the trial group and 65 in the control group. There were significant differences between the two groups in evaluation time of pain (t=–2.736, P=0.007), types and frequencies of temporary rescue medicine (χ2=10.276, P<0.05), the overall postoperative pain score (Z=–2.146, P=0.032), average hospitalization time after surgery (t=–2.468, P=0.015), SER scores 7 days after surgery (F=2.390, P=0.018) and 14 days after surgery (F=3.427, P=0.001), and ROM at the postoperative day 7 (F=2.109, P=0.037); there were no significant differences in postoperative daily pain scores (Z=–1.779, P=0.077), SER scores at the postoperative day 3 (F=1.010, P=0.314), ROM at the postoperative day 1 (F=1.319, P=0.189) and day 14 (F=1.603, P=0.111). Conclusion Self-assessment of pain can motivate TKA patients to take part in pain management, and more accurate response to the pain intensity will help to optimize the management of perioperative pain and reduce the workload of the health staff, thereby contributing to enhanced recovery.
Objective To evaluate the efficacy and safety of local triamcinolone combined with conventional interventional therapy in the treatment of benign airway stenosis. Methods PubMed, Cochrane Library, EMbase, Web of science, wanfang, VIP and China National Knowledge Infrastructure were searched by computer between the establishment of the database and August, 2019, and all literatures on the local treatment of benign airway stenosis using triamcinolone combined with conventional interventional therapy were searched. According to inclusion and exclusion criteria, 2 researchers screened the literatures and performed the data extraction and methodological quality evaluation. Meta-analysis was performed with Revman5.2 and Stata software. Results In total, nine randomized controlled trials were included in this meta-analysis, including 449 patients with airway stenosis. The total result showed that in the comparison of short-term efficacy, there were no statistically significant differences in breathability score (SMD=–0.16, 95%CI –0.45 - 0.13, P=0.27), airway diameter (SMD=0.14, 95%CI –0.13 - 0.41, P=0.30), and cross-sectional stenosis rate (SMD=–0.01, 95%CI –0.36 - 0.34, P=0.96) between the treatment group and the control group. In the comparison of long-term efficacy, the breathability score (SMD=–2.53, 95%CI –3.78 - –1.28, P<0.05), airway diameter (SMD=1.31, 95%CI 0.83 - 1.78, P<0.05), cross-sectional stenosis rate (SMD=2.58, 95%CI: 2.11~3.08, P<0.05), and FEV1(SMD=0.42, 95%CI 0.13 - 0.70, P=0.004) of patients in the treatment group were all better than those in the control group. But in terms of adverse reactions, the incidence of bleeding in the airway between two groups was similar (RR=2.00, 95%CI 0.88 - 4.52, P=0.10), other adverse reactions such as blood glucose and plasma cortisol levels were mild, which can be relieved symptomatically. Conclusion Current evidence suggests that topical triamcinolone combined with conventional interventional therapy for benign airway stenosis has a better long-term clinical efficacy with fewer adverse reactions and better overall patient tolerance, which has clinical application value

Objective To evaluate the real-time contrast-enhanced ultrasonography (CEUS) in the differential diagnosis of retroperitoneal occupying lesions. Methods Thirty patients with retroperitoneal occupying lesions, including 10 benign and 20 malignant lesions, were performed with CEUS, thus describing the perfusion of contrast agent, the entering style of contrast agent and the vascular morphous. And the entering styles were divided into two patterns: peripheral type or central type while the vascular morphous were divided into 4 levels: level 0, level 1, level 2 and level 3. All of these were compared between benign and malignant lesions. Compared the results of diagnosis malignant lesions by common ultrasonography with CEUS. Results 1/5 case of benign substantive lesions presented as contrast agent perfusion defect, and 11/20 cases of substantive malignant lesions presented as contrast agent perfusion defect. 14/20 of malignant lesions were central type; 9/10 of benign lesions were peripheral type (P=0.005 2). In benign lesions, level 0 had 7/10， level 1 had 2/10 and level 3 had 1/10. In malignant lesions, level 0 had 1/20, level 1 had 3/20, level 2 had 8/20 and level 3 had 8/20, too (P=0.000 5). The rate of missed diagnosis was 40.00% and the accuracy was 66.67% by common ultrasonography, while the rate of missed diagnosis was 10.00% and the accuracy was 86.67% by CEUS combined with the entering style of contrast agent and the vascular morphous. Conclusion The CEUS applies a new way to discriminate malignant from benign in retroperitoneal occupying lesions.
Objective To systematically evaluate the effectiveness and safety of macrolides in the prevention of COPD exacerbation. Methods The literatures concerning both randomized controlled trials ( RCTs ) and clinical control study of COPD were searched in PUBMED, EMBASE, Chinese National Knowledge Infrastructure ( CNKI) ,Wanfang, and Chinese Science and Technology Journal Full-text Database ( VIP) ( last updated in September 2012) . The quality assessment and data extraction for RCTs were conducted by two reviewers independently.Meta-analyses were conducted with the Cochrane Collaboration’s RevMan 4. 2 software. Results In all trials, the results indicated that the frequency of acute exacerbation in the macrolide treatment group was decreased compared with the control group [ RR= 0. 63, 95% CI( 0. 50, 0. 79) ] . The frequency of acute exacerbation treated with macrolides was significantly decreased in Asians [ RR= 0. 58, 95% CI ( 0. 44, 0. 75) ] but not in Caucasians [ RR = 0. 79, 95% CI ( 0. 47, 1. 31) ] . The frequency of acute exacerbation treated with roxithromycin was significantly decreased compared with the control group [ RR=0. 54,95% CI( 0. 32, 0. 91) ] . In addition, the macrolides treatment had no side effects except for a few and mild gastrointestinal adverse effects. Conclusion Macrolides may be an effective drug to prevent COPD exacerbation.

Objective To evaluate the safety and effectiveness of modified total arch replacement by retrospectively analyzing the clinical outcome of surgical patients with Stanford type A aortic dissection (AAD). Methods From June 2015 to December 2016, 39 consecutive patients with AAD were recruited to this study. This modified technique was preformed under general anesthesia and a 30℃ hypothermia circulatory arrest (HCA) with continual bilateral antegrade cerebral perfusion. Different surgical approaches were applied according to the aortic root condition: Bentall procedure (4 patients), David procedure (2 patients), aortic valve plasty and ascending aortic replacement (25 patients) and Cabrol procedure (8 patients). Concomitant procedures included mitral valve plasty (1 patient) and tricuspid valve plasty (1 patient). Results The average cardiopulmonary bypass (CPB), aortic occlusion time (ACC), HCA and operation time was 218.5±42.2 min, 134.2±32.4 min, 4.9±2.3 min and 415.5±80.5 min respectively. Four patients required dialysis and 2 patients developed temporary neurological deficit. No permanent neurological deficit, postoperative paraplegia or in-hospital death occurred. Computed tomography examination was performed on all patients before discharge and 3 months after discharge. The follow-up result showed that 37 patients developed complete thrombosis in the false lumen and 2 patients developed partial thrombosis. Conclusion Modified total arch replacement is a safe and effective approach for AAD. It can greatly avoid postoperative complications and provide satisfactory short-term outcomes.
