ObjectiveTo observe the effectiveness of core endurance isokinetic strength training on subacromial impingement syndrome (SAIS) rehabilitation.MethodsSAIS patients were selected from the Rehabilitation Department, Second Affiliated Hospital of Inner Mongolia Medical University from January 2018 to June 2019. The patients were randomly divided into observed group and control group by random number table method. The patients in control group were treated by keritherapy, cold, standard physiotherapy (PT) and exercise. At the same time, the patients in observed group were treated by core endurance isokinetic strength training combined with keritherapy, cold and standard PT. Both two groups were treated for 8 weeks. The patients were scored with visual analogue scale (VAS), Shoulder Pain and Disability Index (SPADI), Short Form 36 Healthsurvey Questionnaire (SF-36), flexor peak torque (FPT) and extensor peak torque (EPT) in pre and post treatment.ResultsA total of 59 patients with SAIS were enrolled. No exfoliating cases. There were 31 cases in the observed group and 28 cases in the control group. Pre-treatment, there were no significant difference in FPT, EPF, VAS, SPADI and SF-36 between the two groups (P>0.05). Post-treatment, there were no significant difference in EPT and VAS between the two groups (P>0.05); FPT [(62.65±10.17) N·m], SPADI [(53.18±10.25) points] and SF-36 [(35.54±11.39) points] in the observed group were significantly improved compared with the control group [(56.28±9.55) N·m, (61.05±9.41) points, (42.65±10.74) points] (t=2.473, 3.061, 2.460; P=0.014, 0.003, 0.017); FPT in both groups, and EPT in the observed group were improved compared with that of the pre-treatment (P<0.05); the EPT of the control group was improved compared with that of the pre-treatment, but the difference was not statistically significant (P>0.05); VAS, SPADI and SF-36 in the two groups were improved compared with those of the pre-treatment (P<0.05).ConclusionsCore endurance isokinetic strength training could improve the core stability of subacromial impingement syndrome patients. Satisfactory musculoskeletal dynamic chain plays a vital role in subacromial impingement syndrome rehabilitation.
ObjectivesTo investigate the awareness and knowledge of Chinese guideline developers on the patient version of guidelines (PVG).MethodsA questionnaire was developed and distributed to participants of the guideline development workshop on the " 2017 Chinese Medical Doctor Association Annual Conference on Evidence-Based Medicine & Gansu Medical Doctor Association/ Gansu Medical Association Annual Conference on Evidence-Based Medicine”, and guideline developers in Shenzhen, Guangzhou, Xi’an, Beijing and other places were investigated through field surveys. The questionnaire included ten questions centred on respondents’ awareness and their views on the development of PVG. After the invalid questionnaire was excluded, Excel 2013 software was used for data entry, and SPSS 19.0 software was used for data analysis.Results150 questionnaires were distributed and 107 (71.3%) were collected, from which 90 (60.0%) questionnaires with complete response were analyzed. For the awareness of PVG: 30.0% of respondents chose " just know it without more knowledge”, 34.4% chose " never heard of”. The awareness was not associated with educational or departmental background, majors and regions (P>0.05). For opinions on PVG and its development process: 86.7% of the respondents thought PVG is necessary, 90% thought the presentation of PVG needs to follow reporting standards, and 45.6% thought the primary barrier of the development of PVG is lack of cognition.ConclusionsResearch work on PVGs is at an initial stage in China. The awareness among Chinese guideline developers and relevant researchers is lacking and the development methodology requires further exploration. Carrying out research relevant to PVG can promote its development and application in China, so as to improve the clinical practice.
ObjectivesTo systematically review the efficacy and safety of intravascular ultrasound (IVUS) and coronary angiography-guided percutaneous coronary intervention (PCI) in left main coronary artery disease. MethodsPubMed, EMbase, The Cochrane Library, CBM, CNKI, VIP and WanFang Data databases were electronically searched to collect randomized controlled trials (RCTs) and cohort studies on the efficacy and safety of IVUS and coronary angiography-guided PCI in left main coronary artery disease from inception to March, 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies; then, meta-analysis was performed using RevMan 5.3 software.ResultsA total of 7 studies involving 7 777 patients were included. The results of meta-analysis showed that: compared with PCI guided by coronary angiography, the incidence of cardiac death (OR=0.45, 95%CI 0.34 to 0.61, P<0.000 01), myocardial infarction (OR=0.67, 95%CI 0.53 to 0.84, P=0.004), major adverse cardiovascular events (OR=0.46, 95%CI 0.34 to 0.61, P<0.000 01), total deaths (OR=0.54, 95%CI 0.44 to 0.67, P<0.000 01), and in-stent thrombosis (OR=0.28, 95%CI 0.18 to 0.45, P<0.000 01) occurred in PCI guided by IVUS were lower. The differences were statistically significant. However, there were no statistical significance in the incidence of target revascularization in PCI (OR=0.80, 95%CI 0.40 to 1.61, P=0.54) and revascularization of target lesions (OR=0.68, 95%CI 0.36 to 1.27, P=0.23) between two groups.ConclusionsCurrent evidence shows that the IVUS-guided PCI can decrease the incidence of cardiac death, myocardial infarction, MACEs, stent thrombosis, total death and has no effect on target lesion revascularization and target vessel revascularization. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusion.
