The Long-Term Effective Rate of Different Branches of Idiopathic Trigeminal Neuralgia After Single Radiofrequency Thermocoagulation: A Cohort Study

To evaluate the efficacy of computed tomography (CT) guided single radiofrequency thermocoagualtion (RFT) in 1137 patients with idiopathic trigeminal neuralgia after a follow-up period of 11 years, specially focused on duration of pain relief in different branches of trigeminal nerve, side effect, and complications.Retrospective study of patients with idiopathic trigeminal neuralgia treated with a single CT guided RFT procedure between January 2002 and December 2013.The mean follow-up time was 46.14 ± 30.91 months. Immediate postprocedure pain relief was 98.4%. V2 division obtained the best pain relief rate: 91%, 89%, 80%, 72%, 60%, and 54% at 1, 3, 5, 7, 9, and 11 years, respectively. No statistical difference pairwise comparison was in other groups. The complications included masseter muscle weakness, corneitis, diplopia, ptosis, hearing loss, limited mouth opening, and low pressure headache. Masticatory weakness mostly occurred in patients with V3 branch involvement, while Corneitis and Diplopia all in patients with V1 branch involvement. No mortalities observed during or after RFT.All different branches division of trigeminal neuralgia achieved comparable satisfactory curative effect; V2 obtained the best excellent pain relief, after RFT procedure. Facial numbness is inevitable after RFT, which patients who have pain in all 3 trigeminal divisions and patients who desire no facial numbness should be cautious. Masticatory weakness is mainly related with V3 injured, while Corneitis and Diplopia in patients with V1 injured by RFT.     

AXL表达与乳腺癌预后及临床病理特征关系的Meta分析

目的 探讨受体酪氨酸激酶AXL蛋白的表达对乳腺癌患者预后及临床病理特征的意义。方法 在中国知网(CNKI)、万方医学网(Wanfang Data)、 Cochrane Library、Embase、PubMed和Medline数据库中,搜索国内外公开发表的有关AXL与乳腺癌预后关系的文献,检索时限均为从建库至2019年10月。2位研究者按纳入和排除标准独立筛选文献、提取资料和评价纳入研究的偏倚风险,并进行Meta分析。结果 共纳入7篇文献,包括933例乳腺癌患者。AXL高表达组的乳腺癌患者总生存期(overall survival,OS)明显低于低表达组(HR=2.36,95%CI 1.60~3.46,P<0.000 1),但其表达在无复发生存期(relapse free survival,RFS)和无疾病生存期(disease free survival,DFS)中差异无统计学意义,且与乳腺癌的年龄、临床分期、组织分级、淋巴结转移及受体表达的相关性分析无统计学意义。结论 AXL的阳性表达与乳腺癌患者预后不良有关,是乳腺癌个体化治疗的潜在分子标志物。     

健康教育个体化对预防急性冠脉综合征的应用研究

目的研究健康教育预防急性冠脉综合征(ACS)的临床治疗效果.方法将62例老年ACS患者分为A组 (常规教育)和B组 (个体化教育),B组通过指导患者制定合适的活动度、掌握缓解疼痛的方式、改善遵医行为、减少冠心病强危险因素以及改变A型行为等方法对患者进行个体化健康教育;A组分小组实施教育.对2组患者康复效果进行对照比较.结果 2组患者的康复有效率:A组低于B组,经统计学分析差异有显著性.结论在ACS患者的诊疗过程中,实施个体化教育对促进患者恢复,减少危险因素的发生具有重要辅助作用.

Application of a pigment measuring device – Mexameter®– for the differential diagnosis of vitiligo and nevus depigmentosus

Background/purpose: Vitiligo and nevus depigmentosus (ND) present similar hypopigmented macules with significantly different prognoses. Although the distinction between the two diseases is important, differential diagnosis relies on medical history and physical examination, which is far from decisive in some cases. The Mexameter^® is an objective skin color-measuring device, and has been reported to provide a reproducible and sensitive means of quantifying small skin color differences. In this study, we investigated the usefulness of a Mexameter^® for discriminating these diseases.
Methods: A selection of 202 hypopigmented skin lesions (182 from vitiligo and 20 from ND) were the objects of this study. Using a Mexameter, MIs were obtained from lesions and symmetrically located control skin. RMIs, ratios of the MIs of lesional skins to control skins, were calculated.
Results: The mean MIs and RMIs were significantly different for vitiligo and ND. The mean RMI of ND lesions was 74±13, which was significantly higher than that of vitiligo lesions (50±24). No ND lesion had an RMI of <50%.
Conclusion: This study shows that the Mexameter^®, an objective pigment-measuring device, can be used to achieve a more accurate diagnosis of hypopigmentary disorders, and that the relative melanin index (RMI), which represents the relative pigment levels, might be a more effective parameter than the melanin index (MI) itself for comparing pigmentation differences.

AMPK在妊娠期糖尿病发病机制中的作用

腺苷酸活化蛋白激酶是一种重要的蛋白激酶,主要作用是协调代谢和能量平衡.腺苷酸活化蛋白激酶被激活后,在增加骨骼肌对葡萄糖摄取、增强胰岛素敏感性、增加脂肪酸氧化以及调节基因转录等方面发挥重要作用.已经证实脂联素有调节糖脂代谢的作用,但其作用机制尚不十分清楚,很可能是通过腺苷酸活化蛋白激酶介导,对脂联素信号转导通路的研究将成为进一步理解脂联素作用的关键所在.而脂联素又是妊娠期糖尿病的预测因子,所以腺苷酸活化蛋白激酶逐渐成为对妊娠期糖尿病研究中的焦点.
