Anterior tibial artery injury is not the contraindication of medial plantar flap: digital subtraction angiography evidence and clinical application

The medial plantar artery (MPA) is often sacrificed as the vascular pedicle of the medial plantar flap (MPF). However, for patients with ankle soft tissue defect caused by traffic accident, the anterior tibial artery (ATA) could be damaged and the blood supply of the distal foot would only come from the MPA and the lateral plantar artery (LPA). In this case, sacrificing the MPA for the MPF means that the LPA will become the mainly source of blood supply of the distal foot. Whether the blood supply of the distal foot is adequately guaranteed remains to be discussed. A total of seven patients with ankle soft tissue defect and ATA injury were enrolled in the study. The digital subtraction angiography (DSA) was performed to observe the hemodynamics of the ipsilateral foot. The MPF was harvested only when the foot arterial network consisting of the MPA, the LPA, the deep plantar arch, and the deep plantar artery of DPA, and the blood redistribution existed. DSA results showed the blood from the posterior tibial artery was redistributed to the ipsilateral foot and the MPA is not the dominant artery in the foot. Seven MPFs were harvested, and all flaps survived completely. No complications, such as pain, ulcer, and necrosis, occurred in the ipsilateral toes. The DSA could accurately and intuitively evaluate the hemodynamics of foot in patients with ATA injury. The DSA data and clinical practice proved that the ATA injury is not the contraindication of the MPF.

芒针透刺督脉组穴配合隔姜灸治疗脑卒中后睡眠障碍疗效及机制研究

目的:以芒针透刺督脉组穴配合隔姜灸对脑卒中后睡眠障碍患者进行干预治疗,观察患者睡眠改善情况及血清5-羟色胺(5-HT)、去甲肾上腺素(NA)和乙酰胆碱(Ach)水平变化,并分析其机制。方法:将同期收治的76例脑卒中后睡眠障碍患者采用随机数字表法分为观察组与对照组各38例。两组均给予脑卒中后常规西医康复治疗,在此基础上对照组辅以传统针灸治疗,观察组采用芒针透刺督脉组穴配合隔姜灸治疗,均连续治疗8周。治疗前后分别测定两组匹兹堡睡眠质量指数(PSQI)、睡眠状况自评量表(SSRS)、美国国立卫生研究院卒中量表(NIHSS)评分,据以计算睡眠障碍治疗总有效率;检测两组血清5-HT、NA和Ach水平,并观察有无不良反应。结果:两组治疗后PSQI、SSRS、NIHSS评分均较治疗前明显降低(P<0.05),且观察组治疗后各评分均明显低于对照组(P<0.05);观察组和对照组睡眠障碍治疗总有效率分别为92.11%、76.38%,两组比较差异有统计学意义(P<0.05);两组治疗后血清5-HT、NA、Ach水平均较治疗前明显提高(P<0.05),且观察组治疗后各指标均明显高于对照组(P<0.05);两组在治疗期间均未发生明显不良反应。结论:芒针透刺督脉组穴配合隔姜灸治疗脑卒中后睡眠障碍安全有效,可明显改善患者预后,机制可能与上调神经递质水平有关。     

内热针治疗中晚期强直性脊柱炎的疗效观察

目的观察内热针治疗中晚期强直性脊柱炎的临床疗效和安全性,探讨其应用前景。方法62例中晚期强直性脊柱炎患者按就诊顺序分为采用内热针治疗的治疗组(31例)和采用常规针刺治疗的对照组(31例),连续治疗8周后观察2组患者治疗前后的主要症状及体征(胸廓活动度、枕墙距、指地距、Schober试验),实验室指标(血沉、C反应蛋白),脊椎疼痛VAS评分、Bath强直性脊柱炎功能指数(BASFI)和Bath强直性脊柱炎疾病活动指数(BASDAI)。结果2组患者治疗后的主要体征、脊柱疼痛VAS评分与治疗前比较均有明显改善(P<0.05);2组之间在枕墙距、指地距、Schober试验、脊柱疼痛VAS评分方面差异有统计学意义(P<0.05),而在胸廓活动方面无明显差异(P>0.05)。治疗前后2组的血沉、C反应蛋白相比有明显降低(P<0.05);治疗后2组在血沉、C反应蛋白无明显变化(P>0.05)。治疗前后2组组内的BASFI、BASDAI相比差异有统计学意义(P<0.05),且组间比较治疗组疗效更佳(P<0.05)。结论内热针疗法和常规针刺疗法对中晚期强直性脊柱炎均有较好的临床疗效及安全性,但内热针疗法在改善脊柱关节活动度、缓解疼痛症状、降低致残率、延缓病情等方面的疗效更为显著,安全可行,值得探索和推广应用。     

Prognostic value of changes in spinal cord signal intensity on magnetic resonance imaging in patients with cervical compressive myelopathy

Background contextSignal intensity on preoperative cervical magnetic resonance imaging (MRI) of the spinal cord has been shown to be a potential predictor of outcome of surgery for cervical compressive myelopathy. However, the prognostic value of such signal remains controversial. One reason for the controversy is the lack of proper quantitative methods to assess MRI signal intensity.PurposeTo quantify signal intensity and to correlate intramedullary signal changes on MRI T1- and T2-weighted images (WIs) with clinical outcome and prognosis.Study designRetrospective case study.Patient samplePatients (n=148; cervical spondylotic myelopathy, n=102 and ossified posterior longitudinal ligament, n=46) who underwent surgery for cervical compressive myelopathy and had high signal intensity change on sagittal T2-WI MRI before surgery between 2006 and 2010.Outcome measureNeurologic assessment was conducted with the Japanese Orthopedic Association (JOA) scoring system for cervical myelopathy. The rate of neurologic improvement was calculated with the use of preoperative and postoperative JOA scores.MethodsQuantitative analysis of MRI signal on both T1- and T2-WIs via use of the signal intensity ratio (SIR; signal intensity of lesion relative to that at C7-T1 disc level) was performed. Correlations between SIR on T1- and T2-WIs and preoperative JOA score, JOA improvement rate, disease duration, and MRI morphologic classification (cystic or diffuse type) were analyzed. Multivariate regression analysis for JOA improvement rate was also analyzed. In a substudy, 25 patients underwent follow-up MRI starting from 6 months after surgery to analyze the relationship between changes in SIR on follow-up MRI and clinical outcome.ResultsSIR on T1-WIs, but not SIR on T2-WIs, correlated with postoperative neurologic improvement. The disease duration correlated negatively with SIR on T1-WIs and JOA improvement rate but not with SIR on T2-WIs. SIR on T2-WIs of “cystic type” was significantly greater than of “diffuse type,” but SIR on T1-WI and JOA improvement rate were not different in the two types. Stepwise multivariate regression analysis indicated that SIR on T1-WIs and long disease duration were significant predictors of postoperative neurologic outcome. SIR on follow-up T1-WI and changes in SIR on T1-WI after surgery correlated positively with postoperative improvement rate. SIR on follow-up T2-WI and changes on T2-WI correlated negatively with postoperative neurologic improvement.ConclusionsOur results suggest that low intensity signal on preoperative T1-WIs but not T2-WIs correlated with poor postoperative neurologic outcome. Furthermore, decreased signal intensity on postoperative T1-WIs and increased signal intensity on postoperative T2-WIs are predictors of poor neurologic outcome.

某中医院校在职教职工脂肪肝与血脂水平的相关性研究

目的 了解某中医院校在职教职工脂肪肝发生率和血脂各指标水平,探讨脂肪肝与血脂各指标水平的相关性。方法 选择某中医院校参加2015年健康体检的715名在职教职工为研究对象,进行体格测量、血脂检测和腹部彩超检查。结果 715名教职工脂肪肝检出率为19.86%,其中轻度和中度检出率分别为17.34%和2.52%,不同性别和年龄教职工脂肪肝检出率间差异具有统计学意义(P＜0.05)。随脂肪肝病情加重总胆固醇(TC)、甘油三酯(TG)和低密度脂蛋白(LDL-C)水平增加而高密度脂蛋白(HDL-C)水平逐渐下降,男性不同程度脂肪肝教职工TG和HDL-C间差异具有统计学意义(P＜0.05),女性不同程度脂肪肝教职工血脂各指标间差异具有统计学意义(P＜0.05)。脂肪肝病情与TC、TG和LDL-C水平呈正相关(P＜0.05),与HDL-C水平呈负相关(P＜0.05)。142名脂肪肝教职工血脂异常检出率为59.86%,其中轻度和中度脂肪肝者血脂异常检出率分别为57.26%和77.78%,与非脂肪肝比较差异具有统计学意义(P＜0.05);男性不同程度脂肪肝教职工TC、TG和HDL-C异常检出率间存在显著差异(P＜0.05),女性不同程度脂肪肝教职工血脂各指标异常检出率间差异具有统计学意义(P＜0.05)。logistic回归分析表明,TC和HDL-C异常是影响男性教职工发生脂肪肝的危险因素,TG和HDL-C异常以及年龄是影响女性教职工发生脂肪肝的危险因素。结论 该校脂肪肝教职工血脂异常检出率较高,脂肪肝与血脂各指标水平具有显著相关性。
