Lateral needling at Lianquan (CV 23) for post-stroke dysphagia: a randomized controlled trial / 中国针灸

OBJECTIVE@#To observe the effect of lateral needling at Lianquan (CV 23) for post-stroke dysphagia, and explore its mechanism.@*METHODS@#A total of 64 patients with post-stroke dysphagia were randomly divided into an observation group and a control group, 32 cases in each group. Both groups were treated with conventional basic treatment. The observation group was treated with lateral needling at CV 23, without needle retaining, once a day. The control group was treated with swallowing rehabilitation training, once a day. Both groups were treated for 5 days a week, with 2 days interval, 1 week as one course and 4 courses were required. Before and after treatment, the Kubota water swallowing test grade and standardized swallowing assessment (SSA) score were compared in the two groups. Before and after treatment, the video fluoroscopic swallowing study (VFSS) was used to measure the hyoid bone movement displacement and pharyngeal delivery time in the observation group.@*RESULTS@#Compared before treatment, the Kubota water swallowing test grade after treatment was improved in the two groups (P<0.05), and the observation group was superior to the control group (P<0.05); the SSA scores after treatment were decreased in the two groups (P<0.05), and the observation group was lower than the control group (P<0.05). Compared before treatment, the hyoid bone movement displacement was increased and pharyngeal delivery time was shortened after treatment in the observation group (P<0.05).@*CONCLUSION@#Lateral needling at CV 23 could improve dysphagia symptoms in patients with post-stroke dysphagia, its mechanism may be related to the increasing of hyoid bone movement displacement and shortening of pharyngeal delivery time.

The risk factors of periprosthetic fracture after hip arthroplasty:a meta-analysis / 中国骨伤

OBJECTIVE@#To explore risk factors of the periprosthetic fracture after hip arthroplasty.@*METHODS@#Potential studies were searched in databases including Pubmed, Embase, Cochrane Library, CNKI as well as Wanfang Database up to November 2018 and references in related literatures. The methodological quality of literature was estimated by Newcastle-Ottawa Scale. Raw data were merged and tested mainly by Revmain 5.3.@*RESULTS@#Seventeen studies in total were appropriate with 90 632 patients. The results revealed that it increased the risk of periprosthetic fracture after hip arthroplasty, including female (=1.62, 95%CI:1.44 to 1.82, =3.@*CONCLUSIONS@#Orthopedics doctors should constantly be cantious about the risk factors including female, revision and diagnosis of rheumatoid arthritis. They are supposed to prevent the periprosthetic fracture by gentle operation during hip arthroplasty and monitoring the functional exercise after operations when the above risk factors occur.

Chronic effects of percutaneous transmyocardial laser revascularization in patients with refractory angina / 中华心血管病杂志

<p><b>OBJECTIVE</b>Conflicting results exist on the therapeutic effects of percutaneous myocardial laser revascularization (PMR) in patients with refractory angina pectoris. This study assessed the effects of PMR on myocardial innervation and perfusion in patients with refractory angina pectoris.</p><p><b>METHODS</b>Patients with refractory angina unsuitable for standard revascularization treatment (PTI and CABG) were randomly divided into medication plus PMR (PMR, n = 17) and medication group (M, n = 13). Coronary sinus noradrenaline (NE) and epinephrine (E) levels, heart rate variability (HRV), total ischemic burden (TIB), and ischemic ST segmental events (STI), myocardial perfusion were evaluated at pre-, immediately post and 12 months post treatment (mean followed up time = 11.6 +/- 4.9 months).</p><p><b>RESULTS</b>In PMR group, one patient developed non-persistent ventricular tachycardia, 2 developed pericardial tamponade and another one patient developed heart failure at 24 h after operation. Coronary sinus NE and E were significantly lower 60 min post PMR compared to pre-PMR and HRV was significantly increased 24 h post PMR. One year post treatments, angina grade was significantly decreased in PMR (1.7 +/- 0.3) than that in M group (0.4 +/- 0.2, P < 0.05) while other parameters were similar between the groups.</p><p><b>CONCLUSIONS</b>PMR induced an early transient denervation and decreased angina grade one year post treatment in patients with refractory angina.</p>
