Correlation Analysis of 5-<i>HTTLPR</i>Polymorphism and Post-Traumatic Stress Disorder in Li and Han Nationalities of Hainan Province

Objective: To analyse the correlation of 5-HTTLPR gene polymorphism and PTSD in Li and Han nationalities of Hainan Province. Methods: Essen trauma inventory (ETI), clinician administered post-traumatic stress disorders scale, (CAPS), tower of Hanoi (TOH), wsiconsin card sorting test (WCST), trail making test (TMT) and wechsler adult intelligence scale revised China (WAIS-RC) were used to investigate patients with PTSD and healthy volunteers (control group). PCR and PPGE were used to detect the polymorphism of 5-HTTLPR gene and analyze its correlation with PTSD. Results: The ETI score, total PTSD score and TMT time of Li nationality patients with PTSD were significantly higher than those of Han nationality patients with PTSD, and the IQ of comprehension and operation in WAIS-RC was significantly lower than that of Han nationality patients with PTSD (P < 0.05). The ETI score, total PTSD score and TMT time of 5-HTTLPR genotype in Li nationality and Han nationality patients with PTSD were significantly higher than those of LL genotype, and the perception, calculation and block diagram in WAIS-RC were significantly lower than those of LL genotype patients (P Conclusions: The SS genotype can increase the risk of PTSD in Li nationality and Han nationality people in Hainan. LL genotype is associated with PTSD of Li and Han nationalities in Hainan, and is an important protective factor for PTSD of Li and Han nationalities in Hainan.

Correlation between plasma VEGFA expression level of chronic obstructive pulmonary disease in Li and Han nationalities in Hainan

Objective:To analyze the relationship between plasma vascular endothelial growth factor and patients with chronic obstructive pulmonary disease in Hainan Li and Han nationality, and the correlation between VEGFA and COPD after different stratification, to explore the significance of VEGFA in the diagnosis and treatment of Li people with chronic obstructive pulmonary disease.Methods:249 patients with COPD were recruited in Hainan (109 cases of Li and 140 cases of Han), and 246 cases in the control group (89 cases of Li;157 cases of Han ) From July 2014 to March 2015, We measured plasma vascular endothelial growth factor protein levels ,and determined the expression difference of plasma VEGFA in patients with chronic obstructive pulmonary disease and healthy controls according to different races, genders, smoking status, etc., and analyzed the correlation between the expression of VEGFA in patients with chronic obstructive pulmonary disease in Li and Han in Hainan.Conclusion:(1) In the Li population, the expression of VEGFA of COPD patients and healthy controls was lower than that of Han (P<0.05);(2) The causes of elevated VEGFA levels in the plasma of the Li population are: high BMI, advanced age, use of wood, hay,recent respiratory infections and AECOPD;(3) The causes of elevated VEGFA levels in plasma in Han population are: COPD, low education level, smoking age, repeated respiratory infection, family history of respiratory diseases, frequent coughing, recent respiratory infection and acute COPD Aggravation period;(4) In the AECOPD, the expression of VEGFA in plasma was higher than that in stable phase and control group;the expression of plasma VEGFA in stable phase of COPD was lower than that in the control group.

Study on the Relationship between 5-HttLPR Gene and BDNF Gene Polymorphism and Post-Traumatic Stress Disorder in Li and Han Nationality of Hainan Province

Objective: To investigate the correlation between 5-HTTLPR (5-and serotonin transporter linked polymer region) gene polymorphism and BDNF (brain derived neural factor) gene polymorphism and PTSD (post traumatic stress disorders) in Li and Han nationalities in Hainan Province. Methods: 167 Hainan Li PTSD patients, 141 Hainan Han PTSD patients and 158 healthy volunteers (control group) were investigated by ETI, caps, Toh, WCST, TMT and WAIS-RC. The polymorphisms of rs6265 locus of 5-HTTLPR and BDNF genes were detected by PCR (polymerase chain reaction) and page (polycylamide gel electrophoresis), and the correlation with PTSD was analyzed. Logistic regression analysis was used to analyze the influencing factors of PTSD. Results: The ETI score, total PTSD score and TMT time of Li PTSD patients were significantly higher than those of Han PTSD patients (P < 0.01). The comprehension, picture filling, picture arrangement, operation IQ and total IQ of WAIS-RC were significantly lower than those of Han PTSD patients (P < 0.01);The numbers of errors, TMT and Toh in WCST were significantly lower than those in Han PTSD patients (P < 0.01). There was no significant difference in the distribution of 5-HTTLPR genotype and allele between Li PTSD patients and control group (P > 0.05). SS genotype of 5-HTTLPR and (GA + AA) genotype of rs6265 locus may increase the risk of PTSD in Hainan Han population. AA and GA + AA genotypes at rs6265 locus may increase the risk of PTSD in Li population (P < 0.05). Among Li PTSD patients, the ETI score, PTSD total score, TMT time, Toh planning time and execution time of AA genotype at rs6265 locus were significantly higher than those of GG genotype;the total scores of comprehension and operation IQ, and Toh in WAIS-RC were significantly lower than those in GG genotype (P < 0.05). Among Han PTSD patients, the ETI score, PTSD total score and TMT time of SS genotype of 5-HTTLPR were significantly higher than those of LL genotype, and the comprehension, arithmetic and block diagram in WAIS-RC were significantly lower than those of LL genotype;The ETI score, PTSD total score and TMT time of patients with (GA + AA) genotype at rs6265 locus were also significantly higher than those of patients with GG genotype. The comprehension and block diagram in WAIS-RC were significantly lower than those of patients with GG genotype. The number of WCST errors in patients with AA genotype was significantly higher than those of patients with GG genotype, and the operational IQ in WAIS-RC was significantly lower than those of patients with GG genotype (P < 0.05). Conclusion: The LL genotype of 5-HTTLPR and the GG genotype of rs6265 locus are related to PTSD of Li and Han nationalities in Hainan, which are important protective factors for PTSD of Li and Han nationalities in Hainan.

王船山夷夏观辨正——以礼以分殊辨别人禽与夷夏为视角

船山是宋明理学的总结者,儒家传统文化的忠实捍卫者,学术界多把他的夷夏观理解为一种狭隘的夷夏观:即从船山的夷夏观推断船山将禽兽与夷狄等同;二是认为船山是典型的华夏主义者,也即大汉族主义者,这是对船山夷夏观的一种误解与误读。如果还原船山原典语境和抽离引用者自身的语境,从礼以分殊辨别夷夏为视角,即可还原船山夷夏观的真实存在:即船山本意并非将夷夏等同于禽兽,同时他也并非主张大汉族主义。一旦抽离船山原典的语境和置换引用者自身的语境,就会导致对船山夷夏观的误解与误读。

石渠阁:西汉国家图书档案馆及其沿革再考——兼探析司马迁在此地编撰《史记》

汉高祖7年(前200)由杨成延总体设计的、丞相萧何主持建造的未央宫建筑群中位于北面的石渠阁(与东面的天禄阁大体平行)为西汉时代的“王朝中央档案馆、皇家藏书阁”,“御史律令图书藏之”,多位群贤司马迁、杨雄等先后工作、探究、“校书著述”于此地,并利用其丰富的档案及图书资料编撰了众多经典文献,其中“史家之绝唱”《史记》也诞生于此;石渠阁“硥石为渠以导水”——防火防盗,时为图书档案馆建筑一伟大之创举,也为西汉国家图书档案馆之“创新性”见证!调研后,有纠错足立喜六观点:“沧池”应在“台地(前殿)”西南;且有补充内容:考古图中所注“马家寨”应为“东马寨”,西边对称位置有“西马寨”;石渠阁毁于王莽末年之兵火中;石渠阁“王莽新政”时期改为铸造钱笵之场所?——发现有“大泉五十背面笵”等文物,待进一步考证——此乃一重大发现之探讨!该背笵呈红色,阴文。并对司马迁在此地所编撰的《史记》进行了探析。

论李白诗歌中的丝路文化色彩

李白是唐代诗人中身上最具有西域和丝路文化色彩的诗人之一。他的西域文化色彩不仅表现在他的诗歌中,更体现在他的家世的西域文化背景上。他的西域情结和西域文化因素不仅是体现在表面的言行风格上,而且也体现在他的骨子里,即思维方式和价值取向上面。他是盛唐时代文化开放和思想开放最具有代表性的诗人。中亚和西域文化的熏陶使李白的诗歌具有巨大的文化魅力和丰富的艺术表现力,这也是他的诗歌成功走向世界的因素之一。
