目的 探讨SNCG蛋白在卵巢癌组织中的表达情况及临床意义,明确SNCG在人卵巢癌中的表达情况及其恶性程度的关系,为临床卵巢癌的诊断、治疗及预后提供理论依据。方法 收集2010年1月—2015年1月石河子大学医学院第一附属医院收治的具有完整临床病理资料和石蜡切片的119例卵巢癌以及50例正常卵巢患者,用免疫组化方法检测组织中SNCG的表达情况,并分析SNCG的表达与卵巢癌患者临床病理特征及预后的关系。结果 SNCG在卵巢癌组织中的表达高于正常卵巢组织(χ²=73.575,P＜0.001);SNCG的表达与卵巢癌患者的肿瘤分期、分化程度、淋巴结转移、达到满意减瘤术、CA125以及HE4水平相关,差异均有统计学意义(P＜0.05);与卵巢癌肿瘤的原发部位、腹水、复发及化疗耐药无关,差异无统计学意义(P＞0.05);SNCG的过表达与HGSOC患者的PFS、OS相关,差异有统计学意义(P＜0.05);多变量Cox比例风险模型分析显示SNCG是HGSOC患者的独立预后因素,与PFS(HR=2.107,95%CI:1.014～3.795,P=0.034)、OS(HR=1.238,95%CI:0.716～1.928,P=0.047)相关。结论 SNCG在卵巢癌中高表达,与患者肿瘤分期、分化程度、淋巴结转移、达到满意减瘤术、CA125以及HE4水平有关,与卵巢癌患者的复发与化疗耐药无关,SNCG蛋白的过表达可作为HGSOC患者的独立预后因素,指导临床诊治。

Objective To detect the expression of SNCG in ovarian cancer tissue and its clinical significance, to clarify the relationship between the expression of SNCG in human ovarian cancer and the degree of malignancy, so as to provide theoretical basis for the diagnosis, treatment and prognosis of clinical ovarian cancer. Methods From January 2010 to January 2015 in First Affiliated Hospital of Medical College of Shihezi University,119 patients with ovarian cancer and 50 patients with normal ovarian which had complete clinical data and paraffin section were selected. Immunohistochemical method was used to detect ovarian SNCG expression, and the expression of SNCG relationship with clinical pathological characteristics and prognosis of patients with ovarian cancer was analyzed. Results The expression of SNCG in ovarian cancer tissue was significantly higher than that in normal ovarian tissue (χ²=73.575,P＜0.001). SNCG expression was correlated with tumor stage, degree of differentiation, lymph node metastasis, satisfying tumor reduction, CA125 and HE4 levels in ovarian cancer patients, and the differences were statistically significant (P＜0.05). It was not correlated with the tumor primary site, ascites, recurrence of ovarian tumor and chemotherapy resistance, and the differences were not statistically significant (P＞0.05).The overexpression of SNCG was correlated with PFS and OS in HGSOC patients, and the differences were statistically significant (P＜0.05). Analysis of multivariate Cox proportional risk model showed that SNCG was an independent prognostic factor in patients with HGSOC, related to PFS (HR=2.107,95%CI: 1.014-3.795,P=0.034) and OS (HR=1.238,95%CI: 0.716-1.928,P=0.047). Conclusion The high expression of SNCG in ovarian cancer is related to tumor stage, degree of differentiation, lymph node metastasis, satisfying tumor reduction, CA125 and HE4 expressions, but it is not related to the recurrence of ovarian cancer or chemotherapy resistance. The overexpression of SNCG protein can be used as an independent prognostic factor in patients with HGSOC for clinical diagnosis and treatment guidance.

目的 探讨机采血小板献血者流失原因,为建立一支稳固的机采血小板献血者队伍提供参考。方法 选择2009年1月1日—2012年12月31日河源市中心血站首次机采血小板献血者共382例为研究对象,根据其首次机采血小板献血后3年内是否再次参加机采血小板献血分为实验组和对照组,分别对研究对象进行电话回访调查。结果 3年内未再次参加血小板献血流失者118例,总流失率为30.89%;不同献血动机组流失率差异有统计学意义 (χ²= 18.552,P=0.000),其中动机不明确组流失率(52.49%)最高,寻求社会荣誉组流失率(15.79%)最低。发生过献血反应组(63.64%)流失率显著高于未发生献血反应组流失率(26.63%),两组间差异有统计学意义(χ²=8.501,P=0.004);对献血过程不满意组流失率(39.77%)显著高于满意组流失率(28.23%),两组间差异有统计学意义(χ²=16.413,P=0.000);认为机采时间过长组机采血小板献血者流失率(49.40%)显著高于不认为机采时间过长组流失率为(25.75%),两组间差异有统计学意义(χ²=17.014,P=0.000)。健康状况(体检结果)不合格组流失率(43.84%)显著高于合格组流失率(27.83%),两组间差异有统计学意义(χ²=9.022,P=0.030)。媒体(或网络)负面的宣传与献血者是否方便对机采血小板献血者流失率的影响不显著(χ²=1.579,P=0.209;χ²=2.130,P=0.144)。结论 机采血小板献血者流失主要与献血动机、献血过程感受以及自身健康等因素有关。
