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.

From Xia People to Han People and to Chinese Nation——A Study of the Trajectory of the Cohesion and Integration of Chinese Ethnic Groups

Building multiethnic China was primarily driven by the cohesion and integration of main ethnic groups within Chinese territory, but the process was recorded according to traditional ethnic group discourse system of ancient China, so there is some doubt whether “nation state” theory can interpret it precisely. This paper manages to figure out the trajectory of cohesion and integration of main ethnic groups propelled by ancient Chinese people from the Xia Dynasty to the late Qing Dynasty by focusing on traditional views on ethnic groups of ancient China. This paper contend that although there were the phenomena of naming the products of the integrations after the regimes they belonged to,“Han people,”“Hua people” and even “Zhonghua(Chinese) people,” became the designations of main cohesive ethnic groups in China over time, and the concept of “Chen Min(subjects)” and the appearance of “nationals” that developed during the Qing Dynasty successfully transformed their identity, which Liang Qichao referred to as “Chinese nation”. Efforts by the rulers of the Qing Dynasty to bridge the gaps between different ethnic groups by developing a community of “subjects”(Chenmin), produced the concept of “Chinese nation” which included the various ethnic groups with the “Han people” as the main group. This new community merely represents the present-day cohesion of the Chinese Nation and the internal integration continues.

Association of Gghrelin Polymorphisms with Metabolic Syndrome in Han Nationality Chinese

Objective To investigate the association of ghrelin gene polymorphisms with metabolic syndrome in Han Nationality Chinese. Methods A total of 240 patients with metabolic syndrome and 427 adults aged above forty years were recruited. Genotypes were determined by polymerase chain reaction and restriction fragment length polymorphism analysis. Results The allelic frequency of the Leu72Met polymorphism was 17.3% in the patient group and 11.9% in the control group （x^2=7.36, P=0.007）. Metabolic syndrome was more prevalent among carriers of the Met72 variant （43.8 vs 33.1%, age- and sex-adjusted odds ratio=1.57, P=0.01）. No Arg51Gln variants were found in our study subjects. Conclusion Rather than being associated with its individual components, Leu72Met polymorphism is associated with metabolic syndrome in the Han Nationality Chinese. Arg51Gln polymorphism is rare in the Han Nationality Chinese.

Analysis of the constitution and health of medical students from different nationalities in Korla, Xinjiang, China

Objective: To better understand nutritional and health status of students from different nationalities, we analyzed the nutritional status and athletic ability of Uygur, Hui, Mongolian and Han nationality among medical students in Bazhou Health School in Korla, Xinjiang, China. Methods: Using stratified cluster sampling, 1644 students from 47 classes in the 2014 and 2015 grades were selected as the study objects from Bazhou Health School, and 1644 students were measured for anthropometry and exercise capacity. Anthropometric measurements were carried out by qualified surveyors in accordance with GB/T 5703-1999 standard. The exercise capacity is based on the test requirements of the 'Student Physical Fitness Health Standard' (revised in 2014) issued by the Ministry of Education and the State General Administration of Sport. All the data were established by Excel 2010 to a database, and the test data were re-entered into SPSS 18.0 software for statistical analysis with double check. Result: Body morphogenetic development level: There were significant differences in height, weight, waist circumference, and upper arm skinfold thickness among different nationalities. The height and weight of Uygur students were significantly higher than those of Han and Hui students;but Waist circumference of Mongolian students was significantly greater than that of Han, Hui, and Uyghur Students. Detection rate for low weight and obesity: Four national student's BMI individual scores have significant differences, but their BMI in scored an average of more than 90 points, student's body mass index is more ideal. Exercise ability: Th ere are significant differences in standing jump and seat flexion, the standing jump of Hui stud ents is higher than that of Han nationality, and the seat flexion of Mongolian nationality is high er than those of Han and Uygur students, while the standing jump and seat flexion of Han natio nality is lower than those of Hui and Mongolian students. Conclusion: There are differences in the nutrition and development status of all nationalities and they have their own characteristics. Uygur students have higher heights and weights than those of Han students;Mongolian students have thicker waistlines;while Han students have higher measurements of upper arm skinfold thickness. There are different characteristic in sports ability in all nationalities.

Ultrasonographic measurement of median nerve cross-sectional area reference values in a healthy Han population from Guiyang,China

High-resolution ultrasonography was used to analyze the nerve cross-sectional area （CSA） of the median nerve at 7 sites： the wrist crease, pisiform bone, hamate bone, 6 cm proximal to the tip of the wrist crease, proximal forearm （where the nerve enters the pronator teres muscle）, 4 cm proximal to the tip of the medial epicondyle, and mid-humerus （mid-point between elbow crease and axilla） in 200 healthy volunteers from Guiyang, China. Results showed similar CSA values between the left and right sides, but the CSA 6 cm proximal to the tip of the wrist crease, proximal forearm, 4 cm proximal to tip of the medial epicondyle, and mid-humerus in males was greater than that of females. Moreover, CSA values at the wrist crease, pisiform bone, and hamate bone were greater in the middle-aged and old groups when compared to the young group, and correlated with body mass and height. Thus, reference values of median nerve CSA of the upper limbs can facilitate the analysis of abnormal nerve conditions.

一份珍贵的学术遗产:1950年代民族问题大讨论再审视

1950年代关于民族问题的大讨论,开启了中国史学界以马克思主义理论为指导研究民族问题的热潮。当时学习的重点是斯大林关于形成民族的四个要素。斯大林强调依照这四个要素衡量,在资本主义出现之前,不可能出现民族,民族只能是资本主义时代的产物。范文澜注意到斯大林论断的适用性问题,著文指出中、欧历史情况不同。欧洲历史进入资本主义时代才有了民族国家,而古代中国早在秦汉时期就已经有了“持久的相当巩固的整体”的王朝国家,“汉民族有它自己的发展过程,并不因为有了资本主义才开始形成民族”。围绕汉民族形成时间问题所展开的大讨论实际上是在马克思主义理论指导下成规模地研讨中华民族形成问题的嚆矢。这场大讨论的丰富成果是一份珍贵的学术遗产。

汉魏六朝北地傅氏籍贯考察——以《宋书·傅弘之传》的载述为中心

魏晋南北朝是一个特殊的时代,关于世族籍贯的认定,不能只是简单地考察地理沿革和家族迁徙等表层问题,而应综合考量家族认同、国家认同、历史认同等诸多层面的历史信息。北地傅氏虽然自汉末以来寄寓关中冯翊境内,此后又流寓江南,但其姓望所系与文化根脉仍在河陇地区(义渠、灵州、泥阳)。其亦文亦武、刚直尚气的家族风尚,正是秦汉以来河陇地区风声气俗的本色呈现。如果将汉末以来北地傅氏的籍贯确定在今陕西耀县境内,不仅与北地傅氏家族兴起于河陇边塞、流离迁徙中仍然情系河陇故土的历史事实不符,而且与门阀制度背景下“寄寓他所”“仍冠旧邦”的时代风气不合,显然不是合理公允的结论。

元白话语言接触研究综述

由于元代特殊的社会文化背景,使得元白话表现出独特的语言接触面貌。目前在语法和词汇方面,学界对其研究可以说表现为从断代的静态描写到历时的动态描写,从文献的混同分析到分类对照考察,且逐渐兼顾汉语本身演变规律和语言融合因素的双重影响。不过研究成果虽多,但也存在研究广度欠缺、研究视域狭窄,对内在机制动因挖掘不够深入等问题。站在长城地带北方话语言接触底层研究的视角上,认为“汉儿言语”并非某个朝代所独有,至少在魏晋南北朝以来不断发展递变,在长城内外已构成“汉儿言语联盟”。站在北方话发展历史的角度观照“汉儿言语”“辽代汉儿言语”“蒙式汉语”“满式汉语”等均是其不同时代的变体。理清这一汉语发展脉络,对我们认识汉语基础方言的演变、认识中华民族多元一体化格局的形成,无疑具有重要的历史和现实意义。

中华民族共同体意识的历史形成与铸牢实践——以浙南畲汉民族“三交”为例

中华民族共同体意识是在各民族交往、交流、交融(简称“三交”)的历史过程中逐渐形成与发展的。浙南畲汉民族“三交”具有典型性与代表性,其行为所体现的以“自在”“自觉”“自为”为特征的中华民族共同体意识发展阶段非常鲜明。在清代,当地畲汉民族已实现了经济、文化、精神由浅至深的交往、交流、交融;而在近现代的革命斗争中,通过党的宣传,中华民族共同体意识逐渐在畲汉人群中“自觉”;中华人民共和国成立后,畲汉民族在党群互动下同舟共济、深入交融,“自为”性得到显现。浙南畲汉民族“三交”所形成的铸牢中华民族共同体意识的历史经验可以为当下民族工作的开展提供重要参考。
