《新雕孙真人千金方》考略

《新雕孙真人千金方》是现今尚存于世的《千金方》古本之一。其篇目结构,文字内容,较诸宋本有较大的不同,更为接近孙氏原著的旧貌,具有较高的文献价值和学术价值。本文着重就其流传概况、版本特点以及刊行年代等进行了探讨。     

Hb Southern Italy: coexistence of two missence mutations (the Hb Sun Prairie alpha2 130 Ala --> Pro and Hb Caserta alpha2 26 Ala --> Thr) in a single HBA2 gene

This study describes a new molecular condition in the alpha(2)-globin gene (HBA2) found in six unrelated families from Southern Italy (Campania and Sicily). This new double mutant form of haemoglobin is called Hb Southern Italy and originated from the coexistence of two known mutations occurring in the same globin gene, HBA2 26 G-->A (Hb Caserta) and HBA2 130 G-->C (Hb Sun Prairie). Hb Sun Prairie was originally observed in Indian patients in either the homozygous state, with severe hemolytic anemia, and in the heterozygous state with microcytosis, or in asymptomatic cases as an alpha-thalassemia carrier phenotype. Hb Caserta was observed for the first time in a Casertian family (South Italy) that displayed a slowmigrating haemoglobin upon investigation. We report the clinical phenotype and molecular study of this new double mutant form of haemoglobin in heterozygous and homozygous subjects, as well as in association with alpha degrees delectional thalassemia.     

妊娠合并主动脉疾病患者围术期管理的临床分析

目的:研究合并主动脉疾病的孕产妇在围术期给予兼顾各主要系统功能和孕产妇需求特点的重症集束化治疗,观察治疗效果。方法:收集2012年12月1日至2018年8月31日,北京安贞医院心脏大血管外科收治合并主动脉疾病并行手术治疗的孕产妇,术后返回心外科监护室(ICU)的18例患者,术后给予集束化治疗。包括:①循环系统:维持心排、调整血管张力、根据容量状态失液成分调整补液速度与种类;②呼吸系统:抗炎性反应、减少肺间质渗出、循环平稳后翻身体疗、中低水平肺复张、拔管后氧合指数PaO2/FiO2<200者行无创正压通气至少6 h;③生殖系统:产妇予催产素、管理宫腔水囊、回奶等治疗,孕妇有分娩先兆与妇产科配合决定分娩方式等;④其他出凝血与神经、内分泌系统治疗;维护肝肾功能,急性肾损伤(AKI)尽早行连续性肾脏替代治疗(CRRT);加强心理护理与ICU早期康复。结果:处理后与入ICU时(0 h)比较:①心率24 h时上升,48 h之后下降;平均动脉压(MAP)24 h时上升,48 h之后下降;乳酸:24 h时较0 h时有明显升高(P<0.05),之后下降,出ICU时明显减低(P<0.05);②呼吸频率无显著性差异;与0 h时比较PaO2/FiO224 h时下降[(235.6±45.7)vs.(167.3±27.5),P<0.05],48 h仍有降低[(235.6±45.7)vs.(186.6±23.2),P<0.05],72 h时无明显差异;③主要合并症:谵妄3例(16.7%),切口愈合不良3例(16.7%),二次气管插管2例(11.1%),肺部感染2例(11.1%),急性呼吸窘迫综合症1例(5.6%);④住院时间(15.0±4.4)d,ICU时间(5.6±2.5)d。结论:主动脉疾病围术期孕产妇呼吸系统及循环系统不稳定于术后24 h时高发,积极集束化处理可有效改善,各系统并发症发生率较高,需注意谵妄发生率及切口愈合情况,综合制定围术期管理方案。     

形神是中医辨证要素的首要元素——中医辨证常用20个基本要素与形神的关系

形,即形体;神,有广义与狭义之分,狭义者言之精神、思维、意识等,广义者指一切生命活动,此处当取狭义之范畴.形与神必须相结合,相统一,此即形神一体观,为人是一个有机整体的重要组成内容,总体归属于中医整体观念的范畴.     

Mediating Variables in a Parent Based Intervention to Reduce Skin Cancer Risk in Children

The present study examined theoretical mediators of a parent-based intervention on sunbathing tendencies and sunburn frequencies based on the work of Turrisi et al. [Turrisi, R., Hillhouse, J., Heavin, S., Robinson, J., Adams, M., & Berry, J. (2004). Journal of Behavioral Medicine, 27, 393–412.]. Three hundred and forty parents in two regions of the United States were educated about the dangers of risky sun behavior and how to convey information about skin cancer prevention to their children. Attitudes toward sunbathing, health beliefs, appearance beliefs, and social normative beliefs were examined and found to be significant mediators of program effects on sunbathing tendencies and sunburn frequencies. The findings are discussed with respect to maximizing the effectiveness of future skin cancer interventions with children.     

宽苞糙苏根降三萜化学成分研究

目的研究宽苞糙苏Phlomis umbrosa var. latibracteata根降三萜类化学成分。方法用硅胶柱色谱、凝胶柱色谱、以及制备高效液相色谱等多种色谱分离手段进行分离纯化,用有机波谱手段鉴定分离得到的化合物结构。结果从宽苞糙苏根的95%乙醇提取物中分离得到8个降三萜类化合物,分别鉴定为糙苏醛A(1)、糙苏酮(2)、糙苏四醇A(3)、糙苏四醇B(4)、糙苏六醇A(5)、糙苏六醇B(6)、糙苏六醇C(7)、糙苏六醇D(8)。结论化合物1为新化合物,化合物3、4、6~8为首次从宽苞糙苏中分离得到的化合物,这些化合物表现出一定的肿瘤细胞抑制活性。
