Interaction between BCSG1 and Hsa-circ-0026352 in genetic susceptibility to invasive breast cancer / 中国肿瘤生物治疗杂志

@#[摘 要] 目的：探讨乳腺癌特异基因1（BCSG1）与Hsa-circ-0026352在浸润性乳腺癌（IBC）遗传易感性中的交互作用。方法：选取2019年6月至2022年5月间武汉市中西医结合医院收治的100例IBC患者作为研究对象，采用免疫组化法检测IBC组织及其相应癌旁组织中BCSG1的表达，将研究对象按照IBC组织中BCSG1蛋白表达的高低分为阴性、弱阳性和强阳性组，统计三组患者的临床病理特征及雌激素受体（ER）、孕激素受体（PR）、表皮生长因子受体-2（HER2）、Hsa-circ-0026352的表达情况，采用Logistic回归方程和最大似然法分析BCSG1表达与上述参数的趋势性和交互作用。结果：与癌旁组织比较，IBC组织中BCSG1蛋白呈高表达（P<0.05）；BCSG1蛋白强阳性表达与淋巴结转移、分化程度、临床分期、HER2表达、 Hsa-circ-0026352表达有关联（P<0.05）；BCSG1强阳性表达与IBC存在交互作用（P<0.05）；BCSG1表达与IBC的交互作用在Hsa-circ-0026352阳性表达中最为显著（趋势P<0.001）；BCSG1表达与IBC的交互作用在临床分期Ⅲ期、低分化程度中最为显著（趋势P<0.001）。结论：BCSG1与IBC患病密切相关，且与Hsa-circ-0026352、临床分期、分化程度存在交互作用，可共同增加IBC患病风险性。

Early clinical experience of transcatheter aortic valve implantation via apical approach for high-risk aortic valve disease in single-center / 中国胸心血管外科临床杂志

@#Objective    To summarize the clinical experience in the treatment of high-risk patients with severe aortic valve disease by transcatheter aortic valve implantation (TAVI) via heart apex approach and to evaluate the early efficacy. Method    Five patients who underwent TAVI via heart apex approach from September 2017 to February 2019 in Henan Thoracic Hospital were retrospectively analyzed, including 3 males and 2 females, aged 65-84 (74.6±4.5) years. Result    All operations were performed through a small left incision into the thoracic cavity (3-5 cm), and then through the J-Valve transport system, the aortic valve was successfully released via heart apex after precise positioning under digital subtraction angiography. One patient developed ventricular fibrillation during the operation, and the operation was completed with the assistance of emergency femoral arteriovenous catheterization cardiopulmonary bypass; one patient underwent percutaneous coronary intervention first because of severe coronary stenosis; one patient had paroxysmal atrial fibrillation during the perioperative period, and had hepatorenal insufficiency and thrombocytopenia after the operation, and was improved after medical treatment; one patient had perivalvular leak during the operation, and was improved after re-implantation of the valve; one patient was in stable condition during operation and recovered smoothly after operation. Surgery was successful in all 5 patients. The follow-up time was 2-19 months, and the early clinical effect was good. Conclusion    The short-term clinical efficacy of TAVI via heart apex approach in the treatment of high-risk severe aortic valve disease is definite and safe, but the long-term and medium-term effects need to be further evaluated.

Advances in early biomarkers of diabetic nephropathy

Summary Diabetic nephropathy is the main cause of chronic kidney disease, and represents the most common and serious complication of diabetes. The exact pathogenesis is complex and not elucidated. Several factors and mechanisms contribute to the development and outcome of diabetic nephropathy. An early diagnosis and intervention may slow down disease progression. A variety of biological markers associated with diabetic nephropathy were found in recent years, which was important for predicting the occurrence and development of the disease. Therefore, this article provides an overview of early biomarkers that are associated with diabetic nephropathy.
