BRAFV600E基因突变对甲状腺良恶性结节鉴别的临床意义

目的分析BRAF~(V600E)基因突变在甲状腺良恶性结节鉴别诊断中的应用价值。方法对2015年10月～2018年2月南昌大学第二附属医院诊治的284例行甲状腺结节切除术或细针穿刺活检术的甲状腺结节患者进行分析,经病理学诊断分为良性结节组(A组)和恶性结节组(B组);B组按BRAF~(V600E)基因检测结果分为B1组(BRAF~(V600E)基因突变型组)、B2组(BRAF~(V600E)基因野生型组)。比较实验对象资料、甲状腺功能、BRAF~(V600E)基因突变情况;比较B组患者各临床病理特征分层的BRAF~(V600E)基因突变率。结果 A组未见BRAF~(V600E)基因点突变,B组BRAF~(V600E)基因突变率为59.0%,两组差异有统计学意义(P0.05)。B组中甲状腺乳头状癌患者BRAF~(V600E)基因突变率为64.58%。甲状腺滤泡状癌及髓样癌中均未检测到BRAF~(V600E)基因突变。B组BRAF~(V600E)基因突变率在结节是否多灶性、结节直径、患者性别方面差异无统计学意义(P0.05);在患者年龄≥45岁、结节点状钙化、包膜外浸润、颈部淋巴结转移、合并桥本甲状腺炎、甲状腺影像报告和数据系统分类分层中BRAF~(V600E)基因突变率的差异有统计学意义(P0.05)。结论 BRAF~(V600E)基因在鉴别甲状腺良恶性结节方面作用显著,且在甲状腺乳头状癌中突变率高,在甲状腺乳头状癌诊断中特异性好。

电针对脑卒中患者软瘫肢体肌张力及运动功能的影响

Objective To investigate the effects of electro-acupuncture on muscular tension and motor function in the flaccid,paralytic limbs of stroke survivors.Methods Seventy-two stroke survivors with flaccid,paralytic limbs were divided randomly into a control group and an electro-acupuncture group.Both grourps received routine therapy and rehabilitation training,but the electro-acupuncture group was also treated with electro-acupuncture.Muscular tension and motor function in the flaccid,paralytic limbs in both groups were evaluated by modified Ashworth scale (MAS)and Fugl-Meyer scores before treatment and at the end of 4 weeks.Results After treatment,in 24 patients of the electro-acupuncture group and 10 patients of the control group muscular tension had increased 1-2 grades.The effectiveness rate(68.57%)in the electro-acupuncture group wag higher significantly than that(27.03%)in the control group(P＜0.01).Fugl-Meyer scores in the electro-acupuncture group were significantlv higher than those in the control group(P＜0.01).Conclusion Electro-acupuncture supplementing traditional rehabilitation improves muscle tension in flaccid,paralytic limbs and promotes the recovery of motor flunction after stroke.
