Resistin is elevated in cystic fibrosis sputum and correlates negatively with lung function

Background

Resistin is an immunometabolic mediator that is elevated in several inflammatory disorders. A ligand for Toll-like receptor 4, resistin modulates the recruitment and activation of myeloid cells, notably neutrophils. Neutrophils are major drivers of cystic fibrosis (CF) lung disease, in part due to the release of human neutrophil elastase- and myeloperoxidase-rich primary granules, leading to tissue damage. Here we assessed the relationship of resistin to CF lung disease.

肺癌靶向治疗研究:以文献计量学和可视化分析描述的热点与趋势

目的:通过文献计量学分析方法，阐述并分析肺癌靶向治疗的研究热点与趋势。方法:文章检索了万方数据库、Web of Science、SooPAT(中国专利)数据库近10年来国内外肺癌靶向治疗的相关文献，以文献计量学方法，分析并归类了肺癌靶向治疗的研究热点与时效变迁的趋势。结果:在万方数据库3 744篇肺癌靶向治疗的中文文章中，发现作用于表皮生长因子受体基因突变位点的分子靶向药物-吉非替尼治疗非小细胞肺癌的研究是中国学者近10年的主要研究热点；在近10年Web of Science数据库中检索到的810篇英文文章及参考文献显示，西妥昔单抗、贝伐单抗、纳武单抗、吉非替尼、厄洛替尼和环唑替尼为这10年肺癌治疗领域靶向治疗的热点药物，而多种靶向药物的联合治疗、晚期非小细胞肺癌的靶向治疗效果和肺癌靶向治疗后的脑转移也成为近5年该领域的国际关注热点；中国肺癌靶向治疗领域的254项有权专利的分析显示，申报了专利的主要药物包括酸敏感的吉非替尼-氟硼二吡咯衍生物、顺铂抗肺癌主动靶向隐形类脂质体等。结论:文章采用文献计量学的量化分析技术，呈现出近10年肺癌靶向治疗已成为该领域专业研究者持续关注的热点，而如何选择正确的靶向药物或药物组合方案来解决肺癌治疗中的耐药性问题，同时最大程度地减少患者的不良反应，以延长患者的生存率，应是未来集中研究的方向。     

eIF4EBP3 was downregulated by methylation and acted as a tumor suppressor by targeting eIF4E/β-catenin in gastric cancer

Gastric Cancer - Epigenetic aberrations of tumor suppressor genes (TSGs), particularly DNA methylation, are frequently involved in the pathogenesis of gastric cancer (GC). Through a methylome...     

Association of genetic variants at MYP10 and MYP15 with high myopia in a Han Chinese population

Background: Previous genome-wide association study (GWAS) has revealed the association between MYP10 at 8p23 and MYP15 at 10q21.1 and high myopia (HM) in a French population. This study is managed to discover the connection between some single nucleotide polymorphism (located at MYP10 and MYP15) and Han Chinese HM.

Methods and Results: This case-control association study contained 1673 samples, including 869 ophthalmic patients and 804 controls. Twelve tag SNPs have been selected from the MYP10 and MYP15 loci and genotyped by SNaPshot method. Among 12 SNPs, rs4840437 and rs6989782 in TNKS gene were found significant association with HM. Carriers of rs4840437G allele and rs4840437GG genotype created a low risk of high myopia (P = .036, OR = 0.81, 95%CI = 0.71–0.93; P = .016, OR = 0.73, 95%CI = 0.56–0.96; respectively). Carriers of rs6989782T allele and rs6989782TT+CT genotype also had a decreased risk of high myopia (P = .048, OR = 0.82, 95%CI = 0.71–0.94; P = .006, OR = 0.74, 95%CI = 0.59–0.92; respectively). Other 10 SNPs displaced nonsignificant association with HM. Additionally, the risk haplotype AC and the protective haplotype GT, generated by two SNPs in TNKS, were considerably more likely to be association with HM (for AC, P = .002 and OR = 1.26; for GT, P = .027 and OR = 0.84).

Conclusions: Our results demonstrated that some heritable variants in the TNKS gene are associated with HM in the Han population. The possible functions of TNKS in the development and pathogenesis of hereditary high myopia still require further researches to identify.     

温经祛瘀汤治疗寒凝血阻型月经不调临床研究

目的:观察温经祛瘀汤治疗寒凝血阻型月经不调对患者临床症状、内分泌激素水平及预后等的改善作用。方法:将120例寒凝血阻型月经不调患者纳入A组(60例)、B组(60例),A组应用常规西医治疗,B组应用常规西医联合中医温经祛瘀汤治疗,对比2组的中医证候评分、内分泌激素水平、临床疗效、不良反应以及复发率。结果:B组治疗后的中医证候评分低于A组(P0.05)。B组治疗后内分泌激素水平优于A组(P0.05)。B组总有效率高于A组(P0.05)。B组不良反应发生率、复发率低于A组(P0.05)。结论:温经祛瘀汤治疗寒凝血阻型月经不调的疗效理想,可快速缓解临床症状,改善内分泌激素水平,且不良反应发生率、复发率低。     

利福霉素类药物治疗结核病的临床应用研究进展

结核病是由结核分枝杆菌复合群引起的传染性疾病，是全球主要的流行病种之一。利福平是当前最主要的一线抗结核药物，因其长期应用和不规范治疗，利福平耐药逐渐增加，利福喷丁、利福布汀等利福霉素类衍生物在抗结核治疗方面起到了重要作用。基于利福霉素类药物的药理及药动学特性，对该类药物在结核病治疗中进行最优用药选择分析，并对该类药物与其他抗结核药物联用进行综述，旨在为利福霉素类抗结核药物的临床用药提供文献依据。
