Orthodontic traction of a transmigrated mandibular canine using mini-implant: a case report and review

The patient in this case is an 11-year-old girl, whose mandibular left canine was transmigrated. The traction to the arch was assisted by using a temporary skeletal anchorage device. After 5 months of poor response to traction, the biomechanics were re-adjusted, obtaining effective traction in to the arch in 12 months. After this period, the treatment was completed with fixed orthodontic appliances.

目的探讨老年髋部骨折患者的手术治疗效果及预后情况。方法选择我院2017年3月～2018年9月收治的98例患者随机分为观察组(n=49)和对照组(n=49)。对照组患者给予常规保守牵引治疗,观察组给予手术治疗。观察比较两组临床疗效、髋关节功能Harris评分及术后并发症发生情况。结果观察组优良率为89.80%高于对照组的79.59%,但差异无统计学意义(χ2=1.968,P=0.161);两组疗效整体比较,差异有统计学意义(Z=-6.928,P=0.000)。治疗后,两组Harris评分与治疗前比较均显著升高,差异有统计学意义(t=-18.663,P=0.000; t=-15.682,P=0.000);且治疗后观察组Harris评分(88.47±15.84)分显著高于对照组(81.36±12.56)分,差异有统计学意义(t=2.462,P=0.016)。观察组术后并发症发生率4.08%显著低于对照组的16.33%,差异有统计学意义(χ2=4.009,P=0.045)。结论手术治疗老年髋部骨折临床疗效显著,可有效改善患者髋关节功能,减少并发症,提高患者生活自理能力及生活质量,值得推广应用。     

Primary esophageal mucosa‐associated lymphoid tissue lymphoma treated by endoscopic submucosal dissection

Primary esophageal mucosa‐associated lymphoid tissue (MALT) lymphoma is rare. There have been few reports about early primary esophageal MALT lymphoma being treated endoscopically. The clinical profile of primary esophageal MALT lymphoma is currently unclear, so it is important to accumulate more information about early esophageal MALT lymphoma. To achieve early detection of esophageal MALT lymphoma, we need more accurate knowledge and information about the macroscopic and morphological features of this tumor. Endoscopic resection is one of the most effective treatments. With respect to the lateral andvertical margins of the resected specimen, endoscopic submucosal dissection (ESD) may be superior to endoscopic mucosal resection for treating early esophageal MALT lymphoma. Here we report the macroscopic appearance of the tumor which is the first successful case of ESD for early esophageal MALT lymphoma.     

Effects of Intermittent Traction Therapy in an Experimental Spinal Column Model

Traction therapy, which is known to be a treatment method for scoliosis, one of many muscles disease, has been used since Hippocrates introduced it. However, the effects of traction therapy are still not clear. In addition, the meridian sinew theory, which is related to muscle treatment and is mentioned in the book on meridian sinews in the Miraculous Pivot of Huangdi's Internal Classic, has not been the subject of much study. For these reasons, experimental spinal models were made for this study to observe and analyze the lengths of vertebral interspaces after intermittent traction therapy, which is known to be excellent among muscle treatment methods, with various tensile forces. The results showed that the effects of intermittent traction therapy were unclear and that it might be harmful, especially when the pain was induced by muscle weakness. Because the results of this study on intermittent traction therapy were different from those expected from osteopathy or craniosacral theory, better studies of the subject are necessary.

Effects of Vitreomacular Traction on Ranibizumab Treatment Response in Eyes with Neovascular Age-related Macular Degeneration

PurposeTo investigate the effects of vitreomacular traction (VMT) on ranibizumab treatment response for neovascular age-related macular degeneration (AMD).MethodsA retrospective review of 85 eyes of 85 patients newly diagnosed with neovascular AMD was conducted. Patients were eligible if they had received more than three consecutive monthly ranibizumab (0.50 mg) treatments and ophthalmic evaluations. Patients were classified into a VMT (+) group or VMT (-) group according to optical coherence tomography imaging. Best corrected visual acuity and central retinal thickness (CRT) measurements were obtained at three and six months after initial injection.ResultsOne month after the third injection, mean visual acuity (VA) increases of 6.36 and 9.87 letters were observed in the VMT (+) and VMT (-) groups, respectively. The corresponding mean CRT values decreased by 70.29 µm and 121.68 µm, respectively. A total 41 eyes were identified as eligible for a subsequent fourth injection; 71.1% of patients (27 eyes) in the VMT (+) group but only 29.8% of patients in the VMT (-) group needed a subsequent fourth injection. Follow-up was extended to six months for 42 of the 85 enrolled patients (49.4%). The trends in VA and optical coherence tomography were found to be maintained at six-month follow-up.ConclusionsVA and CRT appeared to be more improved after ranibizumab treatment in the VMT (-) group compared to the VMT (+) group. VMT might antagonize the effect of ranibizumab treatment in a subpopulation of AMD patients.

不同干预方式对斜方肌在运动中激活模式的影响

目的 分析正常人斜方肌的激活特征,观察不同干预方式对斜方肌异常者激活模式恢复的作用。方法 2017年9月至10月,互联网招募肩关节正常人(正常组,n = 20)和肩关节不适者(观察组,n = 20),在无干预、上斜方肌(UT)静力牵拉、下斜方肌(LT)等长收缩和组合干预后,均完成直臂侧上举、坐姿划船和反向飞鸟动作。测试记录肌电信号的均方根值(RMS),计算最大自主收缩肌电百分比(MVE%),观察激活比例和激活时间。结果 无干预时,与对照组比较,观察组UT MVE%增加(P < 0.05),激活时间提前(P < 0.05);中斜方肌(MT)和LT MVE%降低(P < 0.05),激活时间延迟(P < 0.05);UT/LT和UT/MT增加(P < 0.05)。UT静力牵拉、LT等长收缩和组合训练后,两组不同肌肉MVE%、激活时间、激活比例在不同动作下均有不同程度改变(P < 0.05)。结论 斜方肌三束在不同动作中,激活程度与激活时间不同;在运动开始前进行UT静力牵拉和LT等长收缩可以改善肩关节不适者的斜方肌在运动中的激活模式,有利于肩关节发挥正常功能。
