During the development of science of acupuncture and moxibustion, the acupuncture monographs in Song Dynasty had been respected by scholars. Among those monographs, Tongren Shuxue Zhenjiu Tujing, which was compiled by WANG We-iyi in accordance with the emperor's command in Northern Song Dynasty, collected and collated the doctrine of the past, revised its error, designed and casted the bronze portrait as a model simulation, textually researched on meridian theory, and made a huge contribution for the development of acupuncture and standardization of acupuncture teaching and physician examination. In Southern Song Dynasty, WANG Zhi-zhong compiled the Zhenjiu Zisheng Jing. In this book those who met the traditional Chinese medicine and acupuncture theory and heired own clinical experiences were recorded together with practical guide on clinic. This book was instructive and meaningful to the clinical practice. This paper analyzed the lingual and cultural characters of these two reprehensive acupuncture monographs of Song Dynasty in a new viewpoint, and revealed the irreplaceable literature value, clinical value and cultural value of acupuncture monographs in Song Dynasty from their practicality, inheritance and innovativeness.

BACKGROUND:Autologous micro-skin graft covered with alogeneic skin has become a major means for repair of extremely severe burn wounds. Due to the limitation of the source of alogeneic skin, heterogeneous skin (pigskin) or artificial skin serves as a vector to cover the wound on the clinical use. OBJECTIVE: To observe the curative effect of thin-thickness micro-skin pulping covered with heterogeneous skin for repair of burn wounds in comparison with blade-thickness micro-skin pulping covered with heterogeneous skin. METHODS:A self-control study was performed in 36 patients with severe burns of bilateral limbs. There were 42 pairs of wounds, 32 of which were at joint sites. One or two pairs of III-degree burns treated with escharectomy were selected from each patient for self-control comparison. Covered with heterogeneous skin, thin-thickness micro-skin pulping and blade-thickness micro-skin pulping were used in the trial and control groups, respectively. The expansion ratio was controled at 1:8-1:12 in al patients. Wound healing time, degree of scar hyperplasia within 6 months to 2 years after transplantation, and ratio of reconstruction surgery at joint sites were observed and compared. The removed scars by surgery were analyzed based on the total score of the Vancouver Scar Scale. RESULTS AND CONCLUSION: The average wound healing time was (44.7±1.24) days in the trial group and (49.6±1.41) days in the control group, and there was a significant difference between the two groups (P < 0.05). The trial group exhibited less scar hyperplasia than the control group at 6 months to 2 years after transplantation. Compared with the control group, the ratio of severe scar hyperplasia was significantly less in the trial group (P < 0.05), while the ratio of mild scar hyperplasia was obviously greater in the trial group (P < 0.01). However, there was no difference in the ratio of moderate scar hyperplasia between the two groups (P > 0.05). The reconstructive surgery ratio of the trial group was 38%, significantly lower than that of the control group (59.38%;P < 0.01). The total score on the Vancouver Scar Scale was less in the trial group than the control group (P < 0.05). These findings suggest that the thin-thickness micro-skin covered with heterogeneous skin is likely to be a better treatment to repair large ful-thickness skin burn by increasing the thickness of micro-skin, and it can obtain better wound healing quality.

Objective: To investigate the correlation between takeout food consumption and overweight and obesity among college students in Jiangxi Province, and to provide a scientific basis for overweight and obesity prevention and control among college students and standardizing and managing the present situation of takeout food. Methods: From May to June 2018, 2610 college students were randomly selected from a university in Shangrao, Jiangxi Province. The Chi-square and binary Logistic regression were used to analyze the influences of frequency and type of takeout food consumption on overweight and obesity in college students. Results: The prevalence of overweight and obesity among male students (7.7%) was significantly higher than that among female students (4.1%) (χ2=12.02，P<0.01), and the prevalence of overweight and obesity among college students was statistically significant (χ2=12.54, P<0.01). The prevalence of overweight and obesity (8.8%) among college students from relatively wealthy families was higher than that of other groups. College students who ordered takeout and fast food were 1.8 times more overweight and 1.59 times more obese. Conclusion Regular consumption of takeout food and the type of takeout food, such as "Fast Food Bento", increased the risk of overweight and obesity. Improved healthy takeout food awareness and appropriate practices should be strengthened.

Objective To investigate the association of the DYS527a/b and DYF387S1a/b multi-allele pattern with Y-SNP haplogroups.Methods Samples from 295 unrelated males who carrying the DYS527a/b multi-allele pattern were amplified by the YFilerPlus? kit.The genotypes of their frequency distributions,including three multi-copy loci(DYS527a/b,DYF387S1a/b,DYS385a/b)and other single-copy loci were obtained.The DYS527a/b multi-allele pattern and their haplotypes were examined for the associations with Y-chromosome haplogroups using the AIYSNP42 kit,which contains 42 Y-SNP loci.Based on the above results,the association between the DYS527a/b multi-allele patter and its constituent Y-STR haplotypes and related haplogroups was discussed.Results Among the 295 samples,the DYS527a/b tri-allele pattern and tetra-allele pattern accounted for 97.29%and 2.71%respectively,while the DYF387S1a/b tri-allele pattern and tetra-allele encompassed 54.24%and 4.75%.Null allele was detected in DYS448 in 13.22%of the samples.Here,7 Y-SNPs were deticted such as O-M175 and C-M131 which encompassed 45.76%and 45.08%.The haplogroups of R1-M173,N-M231,D1-M174,J-M304 and F-M89 were less than 13 cases,with frequencies ranging from 4.41%～0.34%.There were Y-STR genotypes differences among haplogroups,as haplogroup O-M175 was represented by 4 genotypes of Y-STR profiles characterized by DYS385a/b(12/12,as well as 12/17,12/18,12/19),DYS392(13),DYS593(16)and DYS393(12),and haplogroup C-M130 was characterized by DYS527a/b(19/20/21),DYS385a/b(11),DYS593(17),DYS390(23),Y_GATA_H4(11),and DYS444(13)and so on.Conclusion The DYS527a/b multi-allele pattern is frequently observed in the Kunming population with haplogroup C-M130.In the samples from haplogroups O,C,R1 and N,the DYS527a/b and DYF387S1a/b haplotypes frequently exhibit the multi-allele pattern.Given the frequencies of different haplogroups and the association between Y-SNP haplogroups and Y-STR loci,it could be helpful to look for more details in the paternal lineage search.
