ObjectiveTo investigate the relationship between p53 gene family and thyroid cancer.MethodThe related literatures in the database were reviewed and analyzed.ResultsThe p53 gene family included p53, p63, and p73. The p53 played an important role in the development of thyroid cancer, especially in the development of undifferentiated thyroid cancer. The different subtypes of p63 might have different roles in the thyroid cancer, so it couldn’t be generally said that the p63 was an oncogene or an anti-oncogene, and the function of its specific protein needed to be further studied. The biological role of p73 in the thyroid cells might be contradictory, depending on the interaction of many different factors, and the interaction between various p73 subtypes and members of the p53 molecular network was still unclear.ConclusionThere is still some controversy about role of p53 gene family in development of thyroid cancer.
颈淋巴结清扫术后乳糜漏是颈部外科手术后比较少见的并发症，国内、外文献［1-7］报道其发生率约为1%～3%，其原因很明确，即术中损伤胸导管或其分支。颈淋巴结清扫术后乳糜漏对生命有潜在威胁，且显著延长患者住院时间、增加医疗费用。尽管手术方法及手术器械不断改进，其发生率并没有明显降低，对于部分难治性乳糜漏目前还没有简单有效的办法。现就颈淋巴结清扫术后乳糜漏的预防及治疗方法介绍如下……
ObjectiveTo summarize the new ideas and new instruments in thyroid surgery. MethodsRelated literatures were reviewed and analyzed. ResultsTotal thyroidectomy had become the preferred option for differentiated thyroid cancer and multiple nodule goiter. The key change of surgery was from recurrent laryngeal nerve-protection to parathyroid-protection. Harmonic scalpel, bipolar coagulation forceps and Ligasure were used to thyroid surgery, which could shorten operation time and reduce operative bleeding. ConclusionThe ideas and techniques of thyroid surgery have changed, total thyroidectomy and parathyroid protection are being paid more and more attentions, and new instruments are used more extensively in thyroid surgery.
ObjectiveTo understand the role of calcitonin testing for the diagnosis and treatment of medullary thyroid cancer (MTC) as well as recent research progress, so as to provide assistance in the early clinical diagnosis and treatment of MTC and improve patients’ prognosis. MethodThe literatures about the role of calcitonin testing in MTC in recent years were reviewed. ResultsIn recent years, both domestic and international scholars had extensively investigated the role of calcitonin in the early detection of MTC and accurate postoperative prognosis assessment. With respect to early diagnosis, advancements had been made in the three main measurement methods: basal calcitonin, stimulated calcitonin, and calcitonin measurement in the thyroid nodule fine-needle aspiration washout fluid. These developments in calcitonin levels had contributed to improved guidance in surgical treatment and prognosis evaluation. While calcitonin monitoring could inform treatment decisions and improve patients’prognosis, numerous challenges remain to be addressed. ConclusionThe study of calcitonin detection can deepen the understanding of MTC, further research on calcitonin related detection in the future will be of great significance for the diagnosis, treatment and prognosis evaluation of MTC.
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.
Objective To summarize the research progress of the treatment of primary hyperparathyroidism (PHPT) in multiple endocrine neoplasm type 1 (MEN1). Method The literature about the treatment of PHPT in MEN1 in recent years was reviewed. Results When the symptoms of MEN1 related PHPT were obvious, surgery was an effective treatment. In addition to conventional total parathyroidectomy with autotransplantation and subtotal parathyroidectomy, less-than subtotal parathyroidectomy, and single gland excision had also been proved to be effective recently. Conclusions Combining the clinical manifestations with the actual involvement of the parathyroid of MEN1 related PHPT patients, personalized selection of appropriate timing and methods of parathyroidectomy can help MEN1 related PHPT patients obtain ideal parathyroid function and ensure the quality of life to the greatest extent.
Objective To compare the disadvantages and advantages of open thyroid surgery when using the harmonic scalpel (HS) vs conventional hemostasis (CH). Methods One hundred and fifty-one patients and 70 patients underwent thyroid surgery with HS or CH respectively. The tumor diameter, incisional length, the total operative time, thyroidectomy time, intraoperative bleeding volume, postoperative drainage volume and surgical complications were compared. The incisional length and the surgical complications in and after learning curve with harmonic scalpel were compared. Results There was no significant difference between the HS and CH group at baseline. Incisional length, total operative time, thyroidectomy time, intraoperative bleeding volume and postoperative drainage volume in HS group were significantly lower than those of CH group (P＜0.001); the surgical complications showed no significant difference between the HS and CH group (Pgt;0.05); the incisional length after learning curve was shorter than that in learning curve in HS group (P＜0.05); the surgical complications after learning curve were significantly lower than that in learning curve in HS group (P＜0.001). Conclusion HS provides significant advantages over conventional hemostasis in open thyroid surgery. However, it can’t be used in a blindly exclusive way but be combined with conventional knot tying appropriately.
