除《七月》外,《豳风》六首诗篇的创作均与周公遭变有关。周公摄政初年,在遭遇管蔡流言时,选择用战争的方式终结流言。返政成王后,面对成王和召公等人的猜忌,出于自保,周公出奔到楚地,直到临终都没有返回王都。与周公遭变相关的文献《诗经·豳风》诸篇在文字上呈现出许多西周中期的特征,文献可能写制于昭穆时期。诗篇重提周公,有两重历史背景。一是周王朝东南方发生了淮夷战争,淮夷人群中存在殷商遗民。周公当年安置殷商遗民,经营东方有成效,此时重提周公,有安抚东南淮夷的作用。二是周公后裔在此时逐渐被起用,后人为纪念周公,写制了为其平反冤情的《豳风》诸诗篇。

Objective： To investigate the relationship between eye injury and laser in-situ keratomileusis （LASIK） surgery in military personnel. Methods： This retrospective study collected the data from 27 evacuation hospitals of Chinese army. All medical records of eye injuries in military personnel admitted to the 27 hospitals between January 2006 and December 2010 were reviewed. Patients＇ detailed information was analyzed, including the injury time, place, type, cause, as well as examination, treatment and outcome. Results： There were 72 eye-injured patients who had been treated by LASIK before. The incidence was risingyear by year. Among them, 69 patients were diagnosed with mechanical ocular injury and 3 with non-mechanical ocular injury; 29 patients had traumatic flap-related complications and 21 patients need surgery. There was statistical difference when compared with those having no refractive sur- gery history. Visual acuity recovered well at discharge. Conclusion： There is a high risk of potential traumatic flap problems after LASIK and it is not recommended in army service.

Peanut cultivation in China spans various ecological zones, each with unique environmental conditions. Identifying suitable peanut varieties for these regions has been challenging due to significant phenotypic variations observed across environments. This study, based on a comprehensive analysis of 256 peanut varieties, selected nine representative varieties(Huayu23, Yuanza9102, Silihong, Wanhua2, Zhonghua6, Zhonghua16, Zhonghua21,Zhonghua215, Zhonghua24) for cultivation in five distinct ecological zones including Chengdu, hefei, Nanjing,Shijiazhuang, and Wuhan. The yield and quality related phenotypic traits of these varieties were thoroughly assessed, revealing a complex interplay between genetic and environmental factors. Principal component analysis(PCA) effectively distinguished varieties based on yield and quality traits. Strong correlations were observed between specific traits, such as seed size and quality components. The G × E interaction was evident, as some varieties consistently performed better in certain environments. Varieties with lower coefficient of variation(CV)values exhibited stable trait expression, making them reliable choices for broad cultivation. In contrast, varieties with higher CV values displayed greater sensitivity to environmental fluctuations, potentially due to specific genetic factors. Two high oleic acid varieties, Zhonghua24 and Zhonghua215, demonstrated remarkable stability in oleic acid content across diverse environments, suggesting the presence of genetic mechanisms that buffer against environmental variations. Overall, this study underscores the importance of selecting peanut varieties based on their adaptability and performance in specific ecological zones. These findings provide valuable insights for peanut breeders and farmers, facilitating informed decisions for improved crop production and quality.

Objective： To investigate the epidemiological characteristics of eye injuries sustained by military personnel in Chinese army. Methods： Eleven military evacuation hospitals located in different regions were selected for this study. We reviewed all the medical records of eye injuries sustained by military personnel between January 2005 and December 2009. Patients＇ information was collected. All data were put into database and analyzed statistically. Results： Totally there were 415 inpatients with eye injuries （442 eyes） and their mean age was 24.40 years. Eye injury accounts for 13.51% of all eye diseases in this study. From 2006 to 2009, the number of eye injury increased gradually. Among them, 175 （42.17%） were injured in leisure time, and 145 （34.94%） in working time. Twenty-two （5.30%） patients had an eye surgery or history of eye disease before injury. In all, 246 patients （59.28%） were sent to evacuation hospital within 24 hours and 64 （56.64%） underwent surgeries in 24 hours after injury. There were 389 patients （93.73%） hospitalized for 1 time. Visual acuities of 187 eyes （42.31%） were grade 1 （≥ 20/40） after injury. When discharge, 349 eyes （78.96%） obtained a visual acuity of grade 1. Conclusion： Eye injury has a very frequent incidence in Chinese army and much more attention should be paid to prevent it.

The Paramesotriton Chang, 1935 genus of Asian warty newts is the second most diverse genus in the family Salamandridae, currently containing 14recognized species from northern Vietnam to southwest-central and southern China. Although species of this genus have been included in previous phylogenetic studies, the origin and interspecific relationships of the genus are still not fully resolved,especially at key nodes in the phylogeny. In this study, we sequenced mitochondrial genomes and 32nuclear genes from 27 samples belonging to 14species to reconstruct the interspecific phylogenetic relationships within Paramesotriton and explore its historical biogeography in southern China. Both Bayesianinferenceandmaximum-likelihood analyses highly supported the monophyly of Paramesotriton and its two recognized species groups(P. caudopunctatus and P. chinensis groups)and further identified five hypothetical phylogenetic cryptic species. Biogeographic analyses indicated that Paramesotriton originated in southwestern China(Yunnan-Guizhou Plateau/South China) during the late Oligocene. The time of origin of Paramesotriton corresponded to the second uplift of the Himalayan/Qinghai-Xizang(Tibetan) Plateau(QTP), rapid lateral extrusion of Indochina, and formation of karst landscapes in southwestern *** component analysis(PCA), independent sample t-tests, and niche differentiation using bioclimatic variables based on locations of occurrence suggested that Paramesotriton habitat conditions in the three current regions(West, South,and East) differ significantly, with different levels of climatic niche differentiation. Species distribution model(SDM) predictions indicated that the most suitable distribution areas for the P. caudopunctatus and P. chinensis species groups are western and southern/eastern areas of southern China. This study increases our knowledge of the taxonomy,biodiversity, origin, and suitable distribution areas of the genus Paramesotriton based on phylogene
