目的 探讨子宫内膜癌构成及临床病理特征。方法 以南平市第一医院2020年1月—2022年6月期间收治的82例子宫内膜癌患者为研究对象,收集其临床资料,通过免疫组织化学染色法检测4种错配修复蛋白表达,并分析错配修复蛋白表达与临床病理特征的关系。结果 82例患者中,70例（85.37%）为子宫内膜样癌,病理组织学类型以G1级30例（42.86%）为主,其他类型较为少见。错配修复蛋白表达总缺失率为35.71%,其中MUTL同源物1（MLH1）单独缺失率为2.86%,错配修复蛋白2抗体（MSH2）为4.29%,错配修复蛋白6抗体（MSH6）为14.29%,肿瘤错配修复基因PMS2抗体（PMS2）为14.29%;错配修复表达缺失（dMMR）组患者年龄50岁以上、伴脉管侵犯和淋巴结转移、组织学G3级和FIGO分期Ⅲ期占比高于错配修复表达正常（pMMR）组患者（P<0.05）;MSH6蛋白表达缺失易发生在年龄50岁以上、有家族相关疾病史的患者（P<0.05）;PMS2蛋白表达缺失易发生在组织学G2级、FIGO分期Ⅲ期、妊娠1次及以上、脉管内癌栓和淋巴结转移的患者（P<0.05）。结论 子宫内膜癌错配修复蛋白表达与其部分临床病理特征存在密切关联,可为患者后续治疗提供有价值的指导。

Objective To investigate the composition and clinicopathological features of endometrial carcinoma．Methods A total of 82 cases of endometrial carcinoma patients admitted to the First Hospital of Nanping City from January 2020 to June 2022 were studied．Epidemiological data were collected,and the expression of 4 mismatch repair proteins were detected by immunohistochemical staining,and their relationship with clinicopathological features was analyzed．Results Among 82 patients,70 cases（85.37%）were endometrioid carcinoma,and 30 cases（42.86%）were mainly G1 grade,other types were rare．The total deletion rate of mismatch repair proteins expression was 35.71%,in which MLH1 alone was 2.86%,MSH2 was 4.29%,MSH6 was14.29% and PMS2 was14.29%．The proportions of dMMR patients over 50 years old,with vascular invasion and lymph node metastasis,G3 grade histology and FIGO stage Ⅲ were significantly higher than those of the pMMR group（P<0.05）．The loss of MSH6 protein expression was more likely to occur in patients over 50 years old with a family history of related diseases（P<0.05）．The deletion of PMS2 protein expression was more likely to occur in patients with histological G2 grade,FIGO stage III,pregnancy of once or more and intravascular cancer thrombin and lymph node metastasis（P<0.05）．Conclusions The expression of mismatch repair proteins in endometrial carcinoma is closely related to some clinicopathological features,which provides valuable guidance for follow-up treatment．

目的 分析多囊卵巢综合征患者性激素水平与胰岛素抵抗关系。方法 此次研究所设置的观察组对象为我院收入的多囊卵巢综合征患者,均在2017年5月—2020年7月入院,入选患者共100例。选取同一时期到我院进行相关检查的健康育龄女性100例作为对照组。分别检测、统计2组女性的性激素[包括性激素黄体生成素(LH)、睾酮(T)、雌二醇(E2)、卵泡刺激素(FSH)]、空腹血糖(FBG)、空腹胰岛素(FINS)以及胰岛素抵抗指数,对性激素水平与胰岛素抵抗关系进行分析。结果 相比于对照组,观察组女性的LH、T水平更高(P＜0.05),E2、FSH水平更低(P＜0.05),且FBG、FINS、胰岛素抵抗指数均更高(P＜0.05)。观察组中,胰岛素抵抗与非胰岛素抵抗患者的性激素水平与胰岛素抵抗指数,胰岛素抵抗女性与非胰岛素抵抗女性的LH、TE2、FSH水平均具有差异(P＜0.05)。LH、E2、FSH水平与胰岛素抵抗指数无相关性(P＞0.05),T水平与胰岛素抵抗指数呈正相关(P＜0.05)。结论 多囊卵巢综合征患者的性激素出现了一定的分泌紊乱现象,其中T水平与胰岛素抵抗具有相关性。

Objective To analyze the relationship between sex hormone levels and insulin resistance in patients with polycystic ovary syndrome. Methods The subjects of the observation group set up in this study were patients with polycystic ovary syndrome admitted to our hospital, all of whom were admitted from May 2017 to July 2020, and a total of 100 patients were enrolled.One hundred healthy women of childbearing age who came to our hospital for relevant examinations during the same period were selected as the control group.Sex hormone [including luteinizing hormone (LH), testosteron (T), estradiol (E2), follicle stimulating hormone (FSH)] levels, fasting blood glucose (FBG) level, fasting insulin (FINS) level, and insulin resistance index were detected and summerized in the two groups of women separately, and the relationship between sex hormone levels and insulin resistance was analyzed. Results Compared with the control group, women in the observation group had higher LH and T levels (P<0.05), lower E2 and FSH levels (P<0.05), and higher FBG, FINS levels, and insulin resistance index (P<0.05). In the observation group, sex hormone levels and insulin resistance index in insulin-resistant and non-insulin-resistant patients, and LH, TE2, and FSH levels in insulin-resistant and non-insulin-resistant women were different (P<0.05). There was no correlation between LH, E2, and FSH levels and insulin resistance index (P> 0.05), and T level were positively correlated with insulin resistance index (P<0.05). Conclusion Patients with polycystic ovary syndrome showed some disturbance in the secretion of sex hormones, among which T level were correlated with insulin resistance.
