Association of single nucleotide polymorphism of vitamin D receptor gene start codon and the suscepbility to prostate cancer in Han nationality in Hubei, China

Aim: To investigate the single nucleotide polymorphism of vitamin D receptor (VDR) gene start codon in the Han nationality in Hubei and its relationship to the susceptibility to prostate cancel (PCa). Methods: The VDR genotypes were determined by poly-merase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in 80 patients with PCa and 96 normal male controls from the Han nationality in Hubei, using endonuclease Fok. Direct sequencing was done in part of the PCR products. Results: The frequency distribution of Fok I alleles in this cohort all followed the Hardy-Weinberg equilibrium. The distribution of genotypes and alleles had no significant difference between PCa patients and the controls (P>0.05). Conclusion: There was no significant relationship between Fok I polymorphism of VDR gene start codon and PCa in the Han nationality in Hubei.

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.

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.

The Future for the Enterprise

The Enterprise regime was intensively negotiated first in the Third United Nations Conference on the Law of the Sea (UNCLOS III) from 1973 to 1982 and then in the UN Secretary General’s informal consultations from 1990 to 1994. The United Nations Convention on the Law of the Sea (hereinafter the “Convention”) is a major achievement of the UNCLOS III and the Agreement Relating to the Implementation of Part XI of the United Nations Convention on the Law of the Sea of 10 December 1982 (hereinafter the “1994 Agreement”) is an achievement of the informal consultations. The Enterprise regime has been dramatically changed in many ways with the adoption of 1994 Agreement. Envisaged as an operational organ of the International Seabed Authority, the outlook of the Enterprise is still unknown. In this connection, this paper highlights a few questions which need to be answered urgently, and proposes the way forward for the operationalization of the Enterprise in terms of legal principles and institutional design.

The Definition of "Nation" and the Formation of the Han Nationality

accepts J. V. Stalin’s Marxist definition of nation, but disagrees with his inference that a nation could not be formed in precapitalist stage. This inference, the paper alleges, is correct for Europe but not completely so for the rest of the world. By focusing on the four characteristics of a nation posed by Stalin and summing up the historical development of ancient Chinese economy, politics and culture, the paper demonstrates that as far back in the Qin-Han period, the Han nationality had already possessed these four characteristics and formed a stable community of people.

Analysis of dynamic smile and upper lip curvature in young Chinese

During smile evaluation and anterior esthetic construction,the anatomic and racial variations should be considered in order to achieve better matching results.The aims of this study were to validate an objective method for recording spontaneous smile process and to categorize the smile and upper lip curvature of Chinese Han-nationality youth.One hundred and eighty-eight Chinese Han-nationality youths(88 males and 100 females) ranged from 20 to 35 years of age were selected.Spontaneous smiles were elicited by watching comical movies and the dynamics of the spontaneous smile were captured continuously with a digital video camera.All subjects’ smiles were categorized into three types:commissure,cuspid and gummy smile based on video editing software and final images.Subjects’ upper lip curvatures were also measured and divided into three groups:upward,straight and downward.Reliability analysis was conducted to obtain intra-rater reliabilities on twice measurements.The Pearson Chi-square test was used to compare differences for each parameters(α=0.05).In smile classification,60.6%commissure smile,33.5%cuspid smile and 5.9%gummy smile were obtained.In upper lip measurement,26.1%upward,39.9%straight and 34.0%downward upper lip curvature were determined.The commissure smile group showed statistically significant higher percentage of straight(46.5%) and upward(40.4%) in upper lip curvatures(P<0.05),while cuspid smile group(65.1%) and gummy smile group(72.7%) showed statistically significant higher frequency in downward upper lip curvature(P<0.05).It is evident that differences in upper lip curvature and smile classification exist based on race,when comparing Chinese subjects with those of Caucasian descent,and gender.

Difference in normal corneal thickness and curvature between Mongolian and Han nationalities

AIM: To investigate the differences in central corneal thickness(CCT) and curvature in myopic patients with different genders between Mongolian and Han nationalities in the Inner Mongolia region.METHODS: Patients with myopia, among whom 122cases(244 eyes) were Mongolian and 150 cases(300eyes) were Han, were selected. Pentacam was used to measure the corneal curvature, whereas CCT was determined by Pentacam, Orbscan and ultrasound pachymetry.RESULTS: Comparisons of the curvature of men and women in Mongolia showed a significant difference(P 【0.05) by comparing of the CCT values measured by three methods in Han and Mongolian in Inner Mongolia, we can draw a conclusion that the CCT values measured by Pentacam are less than the values by Orbscan and ultrasound pachymetry, and there are statistically significant difference in CCT measurement among the instruments except between the Orbscan and ultrasound pachymetry. The CCT values of Mongolians are more than Han people, and the analysis exhibited statistical significance. The CCT values measured by Orbscan in Mongolia of women are more than men, the difference showed statistical significance.CONCLUSION: Corneal curvature in Mongolian females was significantly higher than that in males. However, no significant difference was observed among Han males and females. The CCT values of Mongolian females were higher than those of males. The normal CCT values measured by Pentacam in Mongolian myopic patients were smaller than those obtained by Orbscan or ultrasound. The normal CCT values of Mongolian patients with myopia were higher than those reported for domestic people.
