Identification of deleterious variants in hereditary breast and ovarian cancer (HBOC) susceptibility genes allows for increased clinical surveillance and early detection, and could predict the response to poly (ADP‐ribose) polymerase (PARP) inhibitor in patients with advanced ovarian carcinomas. To determine the prevalence and clinical prediction factors for HBOC syndrome, 882 selected individuals underwent multigene panel testing for HBOC risk assessment during the period from January 2015 to March 2018. Overall, 176 deleterious mutations were observed in 19.50% (n = 172) of individuals. Twenty‐six of 176 mutations could not be retrieved in related public databases and were considered to be novel. Among patients with ovarian cancer, 115 deleterious mutations were identified in 429 patients (48.6%) with significant enrichment for a family history of breast or ovarian cancer syndrome (P < .05). In the breast cancer subgroup, 31 deleterious mutations were identified in 261 patients. Besides BRCA1 (8; 25.8%) and BRCA2 (11; 35.5%), the most frequently occurring genes, an additional 12 deleterious mutations (38.7%) were found in seven other susceptibility genes. Higher mutation incidence (57.9%) was observed in subjects with histories of breast and ovarian cancer. Our results highlighted the genetic heterogeneity of HBOC and the efficiency of a multigene panel in carrying out risk assessment. 相似文献

Relapse‐enriched somatic variants drive drug resistance in childhood acute lymphoblastic leukemia. We used digital droplet‐based polymerase chain reaction to establish whether relapse‐enriched mutations in emerging subclones could be detected in peripheral blood samples before frank relapse. Although limitations in sensitivity for some probes hindered detection of certain variants, we successfully detected variants in NT5C2 and PRPS1 at a fractional abundance of 0.005% to 0.3%, 41 to 116 days before relapse. As mutations in both these genes confer resistance to thiopurines, early detection protocols using peripheral blood could be implemented to preemptively alter maintenance therapy to extinguish resistant clones before overt relapse. 相似文献

The aim of the study was to explore the relationship between college graduates’ dual self-consciousness, job search
clarity and perceived stress, and reveal the mediating role of perceived stress between dual self-consciousness and
job search clarity. In this study, 467 college graduates were investigated using the Dual Self-Consciousness Scale,
Job Search Clarity Scale, and Perceived Stress Scale. After controlling for gender, age, and region, the results
revealed that: (1) private self-consciousness has a significant positive predictive effect on job search clarity; (2)
perceived stress has a significant negative predictive effect on job search clarity; (3) perceived stress plays partial
mediation effects between private self-consciousness and job search clarity; (4) perceived stress plays complete
mediation effects between public self-consciousness and job search clarity; (5) perceived stress has suppressing
effects between public self-consciousness and job search clarity. 相似文献

The third-generation retinoid adapalene triggered DNA damage to induce S-phase arrest in HaCat cells
Cheng Wang Hongyang Li Pengcheng Ma Jianfang Sun Lingjun Li Jun Wei Lei Tao Kun Qian 《Fundamental & clinical pharmacology》2020,34(3):380-388
Epidermal proliferative diseases consisted of a series of common skin diseases, most of which were recurrent chronic skin diseases, and had greatly negative influence on the life quality of patient. Retinoids exhibited vital roles in the treatment of many skin diseases. Our recent study demonstrated that adapalene significantly inhibited the growth of HaCat cells, and the inhibitory activity was stronger than other retinoids, such as all-trans-retinoic acid, acitretin, isotretinoin, tazarotene, and bexarotene. Further study showed that adapalene suppressed the colony formation of HaCat cells, and it dramatically triggered S-phase arrest and apoptosis, rather than G1 phase arrest which was reported in other retinoids in several studies. Additionally, adapalene treatment greatly upregulated the protein expression of DNA damage marker γ-H2AX, which was in accord with the results of the elongation of tail moment by comet electrophoresis analysis. Moreover, DNA damage was triggered and DNA repair was suppressed synchronously with adapalene treatment, which accounted for the mechanism of S-phase arrest induced by adapalene. In summary, our recent work demonstrated that adapalene showed strong anti-proliferation activity in HaCat cells and could be an alternative agent for the epidermal proliferative disease. 相似文献

目的研究破裂前交通动脉瘤手术治疗后患者的认知功能及预后情况。
方法回顾性分析山西医科大学第一医院神经外科自2015年3月至2017年6月连续收治的94例破裂前交通动脉瘤患者的临床资料,应用认知功能电话问卷修订版及工具性日常生活能力量表、改良Rankin量表评价术后患者的认知功能及预后。采用单因素分析及多因素Logistic回归分析术后患者认知功能与预后的影响因素。
结果67例患者完成了术后认知功能及预后的随访评价。单因素分析:Hunt-Hess分级、文化程度是术后患者认知功能的影响因素(P<0.05);Hunt-Hess分级、Fisher分级、年龄、文化程度是患者预后的影响因素(P<0.05)。进一步行多因素分析,高文化程度是术后患者认知功能的独立影响因素(OR=0.073,95%CI:0.008~0.638,P=0.018)。
结论高文化程度是术后患者认知功能的独立影响因素,且是保护因素。 相似文献
