ObjectiveTo summarize and analyze the possible association between thyroid diseases and alopecia areata. MethodThe literatures on the relationship between thyroid disease and alopecia areata in recent years were searched and reviewed. ResultsAmong individuals with alopecia areata, the risk of thyroid disease was heightened. They were more susceptible to autoimmune thyroid conditions, often accompanied by thyroid function abnormalities. Moreover, alopecia areata patients face an increased risk of thyroid cancer. However, in patients with thyroid disease, the change of the incidence of alopecia areata was not completely clear. The risk of alopecia areata was increased in patients with autoimmune thyroid disease, and abnormal thyroid function may be one of the potential reasons for the persistence of alopecia areata. ConclusionsAutoimmune thyroid disease and alopecia areata may have a common disease basis. Patients with alopecia areata are at greater risk of autoimmune thyroid disease and thyroid dysfunction. The increased risk of alopecia areata in patients with autoimmune thyroid disease may be related to abnormal thyroid function.
Obesity is closely related to thyroid function. The concentration of thyroid stimulating hormone (TSH) in obese patients is higher than that in the general population, and TSH will decrease accordingly after weight loss. Leptin is a bridge linking obesity and thyroid hormones, which can affect the release of TSH. There are many kinds of weight-reducing drugs that target the thyroid gland. Among them, thyroid hormone receptor-specific agonists may be potential drugs for future obesity treatment, but further studies are still needed.
目的:探讨甲状腺功能亢进症(甲亢)患者血浆对氧磷酯酶1(PON1)活性变化以及与其它氧化应激指标的关系。方法:分别测定50名对照组和78例甲亢组空腹血浆中游离三碘甲状腺原氨酸(FT3)、游离甲状腺素(FT4)、促甲状腺激素(TSH)、PON1活性、超氧化物歧化酶(SOD)、丙二醛(MAD)、氧化低密度脂蛋白(ox-LDL)及血脂含量,并进行相关性分析。 结果:甲亢患者血浆PON1活性(139 ±64)kU/L,ox-LDL(598.3±58.6)μg/L,MDA(15.11±3.26) μmol/L及SOD(80.2±25.3)NU/mL。对照组上述指标分别为:PON1(168 ±70)kU/L,ox-LDL (446.2±62.2) μg/L,MDA (10.02±3.00) μmol/L,SOD(92.9±26.9)NU/mL。血浆PON1和SOD活性显著低于对照组(Plt;0.01),ox-LDL和MDA水平显著高于对照组(Plt;0.01)。甲亢患者血浆PON1活性与SOD呈正相关(r=0. 381,Plt; 0.05),与ox-LDL、MDA呈负相关(r=-0. 411,r=-0. 445,Plt; 0.01)。 结论:甲亢患者血浆PON1活性显著降低,可能与氧化应激增强有关。
目的 探讨甲状腺功能亢进症(甲亢)围手术期T3、T4水平的变化及其临床意义。方法 检测30例甲亢患者服碘及心得安作术前准备前(a)、术日晨(b)、术中(c)、术后第1天(d)及术后第5天(e)各时相点T3、T4水平。结果 全组患者均未发生甲状腺危象，T3、T4水平a＞b＞c＞d＞e，其中a、b、c高于正常值，d、e值在正常范围。结论 经术前准备，甲亢患者符合临床手术条件时，血T3、T4仍然高于正常水平； 手术未造成甲状腺激素大量释放； 术后12及36小时时段甲状腺危象高发期T3、T4水平不高。
Objective To explore the potential causal relationship between thyroid dysfunction and osteoporosis (OP) through bidirectional two-sample Mendelian randomization (MR) analysis to provide genetic evidence for the risk association between thyroid dysfunction and OP, and provide reference for early prevention and treatment of OP. Methods Causal relationships were estimated based on data from genome-wide association studies for hypothyroidism (n=410141), hyperthyroidism (n=460499), Hashimoto thyroiditis (n=395640), and OP (n=212778). The inverse variance weighted method was used as the main analysis method, and the other four methods were used as the supplementary analysis methods to evaluate the causal effect of thyroid dysfunction and OP. Results The results of inverse variance weighted method showed that hypothyroidism [odds ratio (OR)=1.097, 95% confidence interval (CI) (1.017, 1.183), P=0.017], hyperthyroidism [OR=1.089, 95%CI (1.000, 1.186), P=0.049] and Hashimoto thyroiditis [OR=1.190, 95%CI (1.054, 1.343), P=0.005] were positively correlated with the causal effect of OP. The results of reverse MR analysis did not support that OP would increase the risk of hypothyroidism, hyperthyroidism or Hashimoto thyroiditis (P>0.05). In the bidirectional MR analyses, there was no heterogeneity in Cochran Q detection, MR-Egger intercept test results showed that there was no horizontal pleotropy, and the leave-one-out method analysis results showed that the MR analysis results were reliable. Conclusion Hypothyroidism, hyperthyroidism, and Hashimoto thyroiditis increase the risk of OP, while OP is not found to increase the risk of thyroid dysfunction in reverse studies.
目的 总结甲状腺功能亢进症（甲亢）并肝损害的临床特征与治疗转归。 方法 回顾性分析2009年6月－2010年6月入院诊治的119例甲亢并肝损害患者（肝损害组）的临床特点与治疗转归资料，并与同期247例甲亢不伴有肝损害患者（无肝损害组）作比较。 结果 肝损害组占同期甲亢患者的30.4%，其中108例（90.8%）无明显肝损害的临床表现，以丙氨酸氨基转移酶和天门冬酸氨基转移酶升高为主，多为轻、中度升高；患者高代谢症候群、突眼、甲状腺肿大发生率及肿大程度明显高于无肝损害组，心率明显快于无肝损害组，血清游离三碘甲状腺原氨酸、游离甲状腺素及吸131I率明显高于无肝损害组，而体质量指数则明显低于无肝损害组（P＜0.05）。两组性别、年龄、病程、甲亢类型、甲状腺球蛋白抗体及甲状腺微粒体抗体滴度差异无统计学意义（P＞0.05）。肝损害组患者随访18个月以上，101例131I治疗患者随着甲亢控制，肝功能恢复正常，未见有再发肝损害；18例抗甲状腺药物治疗，其中10例随着甲亢控制，肝功能逐渐恢复正常；8例随着甲亢控制，肝功能逐渐恢复正常，但随着甲亢复发，再出现肝功能损害。 结论 肝损害是甲亢的常见并发症之一，其肝损害症状较轻，多数患者不典型，但并随甲亢病情较重。护肝治疗结合恰当的抗甲亢治疗预后良好。
目的 探讨青少年原发性甲状腺功能亢进（甲亢）手术治疗的可行性。方法 本组76例甲亢患者手术麻醉以颈丛神经阻滞加强化为主； 手术方式为甲状腺大部分切除术，切除腺体组织约80%～90%，残留腺体总量约6～8 g。结果 无手术死亡及甲亢危象病例，术后10例（13.2%）发生并发症11例次，经保守治疗后症状消失。术后得到随访（1～15年）的51例患者中有6例于术后5～8年出现甲亢复发，无术后甲状腺功能低下病例。结论 手术治疗青少年甲亢具有快速安全、疗效持久、费用较低、患者愿意接受的特点，临床上是可行的。
目的:探讨甲状腺功能低下的早产儿血清游离三碘甲状腺原氨酸(Free trilute,FT3)、游离甲状腺激素(Free thyroxin,FT4)、促甲状腺激素(Thyroid stimulation hormone,TSH)水平进行动态态变化及临床意义。方法:我院在2007年11月至2008年4月住院的32例诊断为甲状腺功能低下的早产儿为研究对象,应用放射免疫法检测生后第1天,第7天,第15天,1月和2月血清FT3、FT4、TSH水平。结果:32例诊断为甲状腺功能低下的早产儿中,有窒息史的22例,呼吸窘迫综合症(Respiratory distress syndrome,RDS)10例,单纯性早产5例;出现少吃少动临床症状6例;生后各时期的TSH变化没有统计学差异,生后1、5天与生后1、2月FT3、FT4则可见Plt;0.05具有统计学差异。结论:有窒息和RDS的早产儿中,容易发生甲状腺功能降低,以低甲状腺素血症最为常见,使用左旋甲状腺素后,FT-3、FT-4水平可迅速恢复正常。如果同时存在TSH增高,则TSH水平恢复较慢。
