目的分析慢性心力衰竭患者血清氨基末端B型脑钠肽前体(NT-proBNP)、超敏C反应蛋白(hypersensitive C-reactive protein, hs-CRP)和糖类抗原-125(carbohydrate antigen-125, CA-125)水平特征。方法选取2019年1月-2020年12月沈阳医学院附属第二医院心血管内科收治的82例慢性心力衰竭患者纳入观察组,选取同期进行健康体检的82例健康者纳入对照组。对比分析两组患者血清NT-pro BNP、hs-CRP和CA-125水平,以及观察组治疗前后和不同心功能分级患者血清NT-pro BNP、hs-CRP和CA125水平的差异,分析心功能分级与血清NT-pro BNP、hs-CRP和CA-125水平的关系。结果观察组治疗前血清NT-pro BNP、hs-CRP和CA-125水平高于对照组,差异均具有统计学意义(P<0.05)。观察组治疗后血清NT-pro BNP、hs-CRP和CA-125水平较治疗前降低,差异均具有统计学意义(P<0.05)。观察组心功能Ⅲ级和Ⅳ级患者的血清NT-pro BNP、hs-CRP和CA-125水平高于心功能Ⅰ级和Ⅱ级患者,差异均具有统计学意义(P<0.05)。Spearman相关性分析显示,NT-pro BNP、hs-CRP和CA-125水平与患者的心功能分级呈正相关。结论慢性心力衰竭患者血清NT-pro BNP、hs-CRP和CA-125表达水平高于健康人群,且这3项指标与患者心功能分级呈正相关,可作为慢性心力衰竭患者病情评估的潜在指标。  相似文献

目的探讨高频超声检查结合粗针穿刺活检(CNB)在鉴别乳腺癌中的应用及其与血清糖类抗原153(CA153)、CA125的相关性。方法选取138例乳腺肿块患者,经术后病理检查明确为乳腺癌患者71例作为乳腺癌组,67例乳腺良性病变患者为良性乳腺疾病组,比较各组CNB结果以及血清CA125、CA153水平,分析高频超声结合CNB对乳腺癌的诊断价值。结果138例乳腺肿物患者经高频超声引导下CNB病理检查,发现乳腺良性病变69例(50.00%),乳腺癌69例(50.00%),与肿物切除术后病理检查比较,高频超声引导下CNB检查对乳腺癌的鉴别准确率为94.20%,灵敏度92.96%,特异度95.52%。乳腺癌组患者血清糖类抗原125(CA125)、CA153均高于良性乳腺疾病组,差异有统计学意义(P<0.05)。经Pearson相关分析,超声检查显示肿物边界不清晰、形态不规则、内部回声不均匀、CNB检查恶性的乳腺肿块患者血清CA153、CA125的表达高于边界清晰、形态规则、内部回声均匀、CNB检查良性的患者(P<0.05)。结论肿瘤标志物CA125、CA153的表达与乳腺癌超声表现、CNB检查和术后病理结果密切相关,高频超声引导下的CNB可对乳腺癌进行较准确的鉴别,为乳腺肿块患者提供较准确的治疗指导。  相似文献

PIK3CA encodes a vital component of PI3K-AKT signalling and is commonly mutated in many cancers. Its role has been most well-studied in thyroid neoplasia, demonstrating an association with more aggressive behaviour. The literature surrounding PIK3CA mutations is less well-established in parathyroid, adrenal and pituitary neoplasia. In the parathyroid and adrenal glands it appears more commonly mutated in carcinomas rather than benign neoplasia. In the pituitary, PIK3CA mutations have been identified in neuroendocrine tumours, more commonly in those with invasive growth. A common theme is the co-mutation of PIK3CA and other oncogenes. Additionally, mutations in PIK3CA rarely affect the germline, however germline variants are increasingly being described, with the potential for cancer predisposition as a component of Cowden-like syndrome. PIK3CA-related overgrowth spectrum (PROS) is classically caused somatic mosaic alterations, with those affected displaying rare neoplasia that has not been reported to affect the endocrine organs. Importantly, PIK3CA can sensitise tumours to targeted therapies, in addition to more recently becoming the primary target of newly developed therapeutic agents.  相似文献

Backgroundand purpose: Zinc is an essential element for human health and plays an important role in metabolic, immunological and other biological processes. The present study was conducted to investigate the association between zinc deficiency (ZD) and the perioperative clinical course in patients with pancreatic ductal adenocarcinoma (PDAC).MethodsOf 216 patients with PDAC who underwent elective pancreatectomy between 2013 and 2017 at our institution, 206 patients with sufficient clinical data were retrospectively reviewed. The perioperative variables were compared and the risk factors associated with infectious complications were identified.ResultsZD was preoperatively present in 36 (17.5%) of 206 patients with PDAC. In the patients of the ZD group, a higher proportion of males, higher preoperative modified Glasgow prognostic scores, a higher neutrophil-to-lymphocyte ratio, and a higher occurrence of postoperative infectious complications after pancreatectomy were observed, compared to the non-ZD group. By a univariate analysis, three risk factors were significantly associated with infectious complications after pancreatectomy: ZD (vs non-ZD: p = 0.002), serum albumin <3.5 g/dl (vs ≥ 3.5 g/dl: p = 0.005), and the procedure of pancreaticoduodenectomy (vs others: p = 0.013). By multivariate logistic regression analysis, the occurrence of infectious complications was significantly associated with ZD (OR 3.430, 95%CI 1.570 to 7.490, p = 0.002) and the procedure of pancreaticoduodenectomy (OR 2.030, 95%CI 1.090 to 3.770, p = 0.025).ConclusionsThe current study newly demonstrated that ZD could serve as a preoperative predictor of infectious complications after pancreatectomies in the patients with PDAC.  相似文献

The gut microbiota and the bile acid pool play pivotal roles in maintaining intestinal homeostasis. Bile acids are produced in the liver from cholesterol and metabolized in the intestine by the gut microbiota. Gut dysbiosis has been reported to be associated with colorectal cancer. However, the interplay between bile acid metabolism and the gut microbiota during intestinal carcinogenesis remains unclear. In the present study, we investigated the potential roles of bile acids and the gut microbiota in the cholic acid (CA; a primary bile acid)‐induced intestinal adenoma‐adenocarcinoma sequence. Apc min/+ mice, which spontaneously develop intestinal adenomas, were fed a diet supplemented with 0.4% CA for 12 weeks. Mice that were fed a normal diet were regarded as untreated controls. In CA‐treated Apc min/+ mice, the composition of the gut microbiota was significantly altered, and CA was efficiently transformed into deoxycholic acid (a secondary bile acid) by the bacterial 7α‐dehydroxylation reaction. The intestinal adenoma‐adenocarcinoma sequence was observed in CA‐treated Apc min/+ mice and was accompanied by an impaired intestinal barrier function and IL‐6/STAT3‐related low‐grade inflammation. More importantly, microbiota depletion using an antibiotic cocktail globally compromised CA‐induced intestinal carcinogenesis, suggesting a leading role for the microbiota during this process. Overall, our data suggested that the crosstalk between bile acids and the gut microbiota mediated intestinal carcinogenesis, which might provide novel therapeutic strategies against intestinal tumor development.  相似文献

目的:探讨血清CEA、CA72-4及CA125联合诊断胃癌术后腹膜转移的价值,为临床诊治提供参考。方法:以我院于2015年11月至2016年11月因胃癌术后在本院复查且相关临床资料齐全患者120例作为研究对象并进行回顾性分析,按照有无腹膜转移分为转移组(38例)和无转移组(82例)。对比两组患者的血清CEA、CA72-4及CA125变化及单项诊断效能,并采用ROC曲线法对比三种肿瘤标志物的诊断效能。结果:转移组患者的血清CEA、CA72-4及CA125水平均高于无转移组,差异有统计学意义(P<0.05)。三个单项指标比较,CA125灵敏度为73.3%,特异度为81.8%,均为三者最高,差异均有统计学意义(P<0.05)。联合诊断比较,CEA+CA72-4+CA125联合检测的灵敏度最高(91.7%),但特异度最低(41.7%),差异均有统计学意义(P<0.05)。结论:胃癌术后腹膜转移患者血清CEA、CA72-4及CA125均升高,且单项诊断CA125的灵敏度及特异度最高,而三项联合诊断的灵敏度最高,但特异度最低,值得临床参考。  相似文献

BackgroundThe relationship between weight change during treatment and survival remains poorly characterized in patients with metastatic renal cell carcinoma (mRCC).Patients and MethodsIn this retrospective analysis we included 3311 patients with mRCC treated in phase II/III first-line or second-line targeted therapy clinical trials and assessed the effect of weight change on overall survival (OS), progression-free survival (PFS), and objective response rate (ORR) at 6 and 12 weeks from treatment initiation. Weight change was defined as weight loss (≥5% reduction), weight gain (≥2% increase), or stable weight from baseline. Survival analyses were performed using the Kaplan–Meier method and adjusted for known prognostic factors using Cox regression multivariable analysis.ResultsOverall, 1916 (58%) had stable weight, 936 (28%) had weight loss, and 459 (14%) had weight gain at 12 weeks. Patients with weight loss at 12 weeks had inferior OS compared with those with stable weight (hazard ratio [HR], 1.494; 95% confidence interval [CI], 1.322-1.688; P < .0001; median OS 18.7 vs. 26.9 months), and shorter PFS (HR, 1.315; 95% CI, 1.189-1.455; P < .0001; median PFS, 7.2 vs. 10.1 months). The ORRs for patients with weight loss, stable weight, and weight gain at 12 weeks were 23.4% (n = 219/936), 32.1% (n = 615/1916), and 35.9% (n = 165/459), respectively (adjusted odds ratio, 0.715; P = .03). Findings were consistent at 6 weeks. Adverse events were similar between groups.ConclusionWe showed that mRCC patients who experience weight loss during treatment have worse outcomes compared with patients with stable weight at 6 and 12 weeks of treatment. Weight loss at 6 weeks from treatment initiation might be an early clinical biomarker of worse survival and might provide prognostic utility.  相似文献
