目的:探讨低氧预适应(hypoxic preconditioning,HPC)条件下对小鼠自然杀伤细胞(natural killer cell,NK)杀伤活性与功能的影响。方法:将小鼠分对照组(A组)、急性低氧组(B组)和HPC组(C组)3组,通过MTT比色法分别检测3组小鼠NK细胞的杀伤活性,通过EILSA检测NK细胞分泌干扰素-γ,Real-time PCR检测穿孔素、颗粒酶的表达量,并采用SPSS 19.0统计学软件进行数据分析。结果:低氧预适应组与急性低氧组相比NK杀伤力较强(P<0.05),其中12 h时NK细胞活性明显增强(P<0.05)。小鼠NK细胞分泌IFN-γ从4 h到16 h均逐渐下降(P<0.05),显示低氧预适应组随着时间的延长较低氧组更能适应低氧;HPC组与B组相比低氧损伤减轻,分泌穿孔素、颗粒酶表达多于低氧组(P<0.05)。结论:初步确定NK细胞在HPC与低氧组相比,NK细胞杀伤功能有所恢复;IFN-γ、穿孔素、颗粒酶蛋白的分泌量均有所升高。

目的:探讨2型糖尿病(T2DM)病人与正常人群间的胸腰椎椎体骨密度(BMD)的分布差异。方法:选取T2DM病人68例作为观察组,选取同期健康体检者96名作为对照组。基于定量CT测量T_(11)~L_(4)椎体的BMD。2组再根据体质量指数(BMI)、年龄和性别分为不同亚组,比较2组一般资料、不同年龄分组胸腰椎骨质疏松症(OP)发生率、不同BMI分组胸腰椎BMD和不同性别分组胸腰椎BMD。结果:观察组病人BMI和空腹血糖均高于对照组(P0.05)。结论:随着年龄的增加,T2DM病人和健康人群胸腰椎BMD均降低,BMD降低与性别和BMI有关;T2DM病人更易发生OP。因此,T2DM病人应加强椎体BMD的相关检查,尽早采取措施缓解骨量减少及预防OP的发生。

The variations in precipitation have displayed a complex pattern in different regions since the *** formation processes may have a significant impact on precipitation,especially during the tropical marine processes and summer monsoon which convey abundant water vapor to coastal southern China and inland ***,we use two 7500 year sedimentary records from the Pearl River Delta and the closed Maar Lake,respectively,in coastal southern China to reconstruct the mid-to-late-Holocene humidity variability and explore its possible relationship with cloud cover modulated by the Earth’s magnetic fields(EMF).Our proxy records document an apparent increase in wetness in coastal southern China between 3.0 and 1.8 kyr *** apparent increase in humidity appears to be consistent with the lower virtual axial dipole moments and,in turn,with a lower *** correlation suggests that the EMF might have been superimposed on the weakened monsoon to regulate the mid-to-late-Holocene hydroclimate in coastal southern China through the medium of galactic cosmic rays,aerosols,and cloud ***,further investigations are needed to verify this interaction.
