Optimal storage temperature and 1-MCP treatment combinations for different marketing times of Korla Xiang pears

Maintenance of green color is the primary indicator of quality in the market evaluation of Korla Xiang pears at present and can generally be achieved through early harvesting and decreasing the storage temperature, but the fruit quality was reduced by early harvesting, and the decreasing storage temperature increased the risk of chilling injury. The objectives of this study were to determine the optimal storage parameters for different storage times and to find ways to preserve the green skin color of pears. Specifically, we analyzed the effects of the ethylene inhibitor, 1-methylcyclopropene （1-MCP）, combined with low temperature on quality and maintenance of the green color of Korla Xiang pears during storage. We found that 1-MCP and/or low temperature reduced the loss of green color at 20℃ after being removed from cold storage. In addition, 1-MCP significantly inhibited the decline of titratable acid and ascorbic acid but had no significant effect on fruit firmness and total soluble solids. Low temperature with or without 1-MCP inhibited the release of ethylene, inhibited the decline in the stalk preservation index, inhibited the increase in decay rate and weight loss rate during storage, and inhibited the increase in the core browning index after 225 days of storage. Different storage temperatures had different effects on the quality of Korla Xiang pears. Despite inhibiting ethylene release, a storage temperature of-1.5℃ increased the respiration rate. Storage at -1.5℃ caused core browning eady during storage due to chilling injury, whereas at 2℃ core browning occurred late during storage due to senescence. In late storage, 1-MCP had no significant effect on the maintenance of Korla Xiang pear quality at 2℃. Based on these results, we determined the optimal combinations of low temperature and 1-MCP treatment to maintain pear quality while avoiding chilling injury. For different marketing times, the optimal conditions for storage until New Year＇s Day （a storage duration of 90 days） are 2℃ or 1-MCP combined with 2℃. For storage until the Spring Festival （a storage duration of 150 days）, the optimal conditions are 0℃ or 1-MCP combined with 0℃, and for storage until May （a storage duration of 225 days）, the best conditions are 1-MCP combined with -1.5℃.

Genomic and transcriptomic analyses reveal selection of genes for puberty in Bama Xiang pigs

The Bama Xiang pig （BMX） Chinese indigenous breed is a famous early-maturing with a two-end black coat To uncover the genetic basis of the BMX phenotype, we conducted comparative genomic analyses between BMX and East Asian wild boars and Laiwu pigs, respectively. Genes under positive selection were enriched in pathways associated with gonadal hormone and melanin synthesis, consistent with the phenotypic changes observed during development in BMX pigs. We also performed differentially expressed gene analysis based on RNA-seq data from pituitary tissues of BMX and Large White pigs. The CTTNBP2NL, FRS2, KANK4, and KATNAL1 genes were under selection and exhibited expressional changes in the pituitary tissue, which may affect BMX pig puberty. Our study demonstrated the positive selection of early maturity in the development of BMX pigs and advances our knowledge on the role of regulatory elements in puberty evolution in pigs.

Variation of Serum Protein Level in Xiang Piglets at Different Month of Age

Usual clinieal methods were used to determine the concentrations of scrum protein, albumin and globulin in Xiang piglets from the 1st month to the 6th month of age. Thirteen piglcts(cight males and five females) born in Spring were selected from the Livestock Experimental Station of NEAU. The results showed that the scrum protein level was different at different month of age. The lowest level was found at the 1st month of age, and the highest at the 4th month of age. The difference in scrum protein concentration was significant between different months of age. There was, however, no significant difference between sexes at the same month of age.

Mu-Xiang-You-Fang protects PC12 cells against OGD/R-induced autophagy via AMPK/mTOR signaling pathway

OBJECTIVE Mu-Xiang-You-Fang(MXYF)is a classic prescription of Hui medicine,composed of five herbs,which has been used to treat ischemic stroke for many years.However,the potential pharmacological mecha⁃nisms of MXYF remain unclear.The present research is to investigate the neuroprotective effect of MXYF and its role in modulating autophagy via AMPK/mTOR signaling pathway in the PC12 oxygen-glucose deprivation and reperfusion(OGD/R)injury model.METHODS MXYF was extracted by supercritical CO2 fluid extraction apparatus.PC12 OGD/R injury model was established by oxygen-glucose deprivation for 2 h and reperfusion for 24 h.The effects of MXYF on the viability and cytotoxicity of PC12 cells were determined through cell counting kit(CCK-8)assay.Colorimetric method was performed to determine the LDH leakage rate.The calcium concentration was determined by chemical fluorescence method and the mitochondrial membrane potential was determined through flow cytometry.Monodansylcadaverine(MDC)staining was conducted to detect autophagosome formation.The expression of LC3,Beclin1,p62,p-AMPK,ULK1,p-mTOR and p-p70s6k proteins were determined by immunofluorescence and Western blotting analyses.RESULTS MXYF(1,2 and 4 mg·L^-1)could significantly increase the cell viability and mitochondrial membrane potential,while decreased the release of lactate dehydrogenase(LDH)and calcium concentration in PC12 cells.Mechanistic studies showed that MXYF reduced the LC3-II/LC3-I ratio and inhibited the expression of beclin1,p-AMPK and ULK1.In comparison,the expres⁃sion of p-mTOR,p-p70s6k and p62 were significantly enhanced.CONCLUSION MXYF inhibits autophagy after OGD/Rinduced PC12 cell injury through AMPK-mTOR pathway,thus MXYF might have therapeutic potential for treating the ischemic stroke.

The Influence of Miao Nationality’s Culture in Yuan Xiang Region on the Later Poetry Creation of Qu Yuan

Miao culture is one of the minority cultures in China.It also has a certain impact on the development of Chinese literature and poetry.Chu ci is a new poetic style created by Qu Yuan,an ancient poet in China.It is the first collection of romantic poetry in the history of Chinese literature.Qu Yuan’s poetry creation is related to his life experience.Qu Yuan was exiled to Yuan Xiang region,and he had been in contact with the Miao ancestors in Yuan Xiang area during the exile.Therefore,the Miao land culture in Yuan Xiang area has a profound influence on Qu Yuan’s later poetry creation.This paper,taking Qu Yuan’s later poetry as an example,analyzes the influence of Miao culture on Chu ci in Yuan Xiang area,introduces Qu Yuan’s life and how to contact Miao culture,and probes into the influence of Miao nationality’s religious thought,customs,language and culture,oral folk song and pan song on the later poetry creation of Qu Yuan.
