Abstract	As an important human capital investment, education is an effective means to improve the comprehensive quality of people. Education expenditure is an important material guarantee for the development of educational undertakings. Education expenditure data is highly susceptible to numerous economic and social factors that complicate its nonlinear structure. In order to model the complex nonlinear problems of the system, this paper proposes a generalized conformable fractional-order nonlinear grey prediction model for the first time by analyzing the traditional time series-based modeling method in a nonlinear grey domain. The proposed model expands on the classical grey Bernoulli model by introducing the generalized conformable fractional accumulation as a new accumulation generator and utilizes error minimization principles in the modeling process. By altering the optimal order of the model and the cumulative generation operator, this model can adapt to various time series and reduce errors. Finally, the model is applied to education expenditure forecasting, and it is proved that the proposed model achieved good results and has higher accuracy than other models.

Abstract	Based on the organization structure of the Flash animation files, we first use the edge density method to segment the Flash animation to obtain the visual scenes, then extract the visual features such as color and texture as the input parameters of BP neural network, and set up the sample database. Secondly, we choose a suitable model for emotion classification, use eight kinds of emotional adjectives to describe the emotion of Flash animation, such as warm, delightful, exaggerated, funny, desolate, dreary, complex, and illusory, and mark the emotion value of the visual scene in the sample database and so use it as the output parameter of the BP neural network. Finally, we use BP neural network with appropriate transfer function and learning function for training to obtain the rules for mapping from visual features of the visual scene to semantic space and, at last, complete the automatic classification work of emotional semantic of the visual scene. We used the algorithm to carry on the emotional semantics recognition to 5012 visual scenes, and the experiment effect is good. The results of our study can be used in the classification, retrieval, and other fields of Flash animation based on emotional semantics.

Abstract	To establish a relatively stable internal haemorrhoid model in rats. A total of 48 SPF SD rats were selected and randomly divided into a blank group of 16 and a model group of 32. The model was created by croton oil-mixed liquid stimulation combined with standing and swimming experiments, and the modelling times were 1 week and 2 weeks, respectively. By observing the symptoms and signs of rats, pathological morphology and immunohistochemical staining of anorectal tissue, anorectal laser speckle blood-flow imaging and defecation contrast, etc., the effect of different modelling times was evaluated. The stability of the model was evaluated after feeding for 2 weeks. Both model-formation times caused rats to produce local symptoms of tissue bulging in the haemorrhoid area. Microscopy showed that the rectal submucosal interstitial blood vessels were dilated, and inflammatory cell infiltration and other manifestations were observed. Laser speckle blood-flow imaging revealed increased anorectal blood perfusion and capillary dilatation, and defecography showed a longitudinal and continuous rectal mucosa. After 2 weeks of normal feeding, lifting of the haemorrhoidal tissue was still present. The effect of modelling for 1 week was most in line with the clinical manifestations of internal haemorrhoids. The 1-week modelling scheme in this study can effectively establish a rat internal haemorrhoid model that closely approximates clinical internal haemorrhoid symptoms and pathological manifestations. The operation is simple, the success rate is high, and the model has certain stability. This model can be used as an important basis for studying various treatment methods for internal haemorrhoids.

Abstract	Diffuse venous malformations (VMs) are relatively rare, especially the lesions locting special anatomical sites, and they are prone to casuse localized intravascular coagulopathy (LIC). Diffuse VMs can also cause bleeding and life-threatening disseminated intravascular coagulopathy (DIC) from trauma, surgery, and improper treatments. Thus, the treatment of diffuse VMs with LIC is quite tough. We report of a diffuse VMs with severe LIC that was treated with the combined use of minimally invasive treatment and open surgery.

Abstract	Oxygen metabolism is closely related to the intestinal homeostasis environment, and the occurrence of many intestinal diseases is as a result of the destruction of oxygen gradients. The hypobaric hypoxic environment of the plateau can cause dysfunction of the intestine for humans, such as inflammation. The compensatory response of the small intestine cells to the harsh environment definitely changes their gene expression. How the small intestine cells response the hypobaric hypoxic environment is still unclear. We studied the rat small intestine under hypobaric hypoxic conditions to explore the transcriptional changes in rats under acute/chronic hypobaric hypoxic conditions. We randomly divided rats into three groups: normal control group (S), acute hypobaric hypoxia group, exposing to hypobaric hypoxic condition for 2 weeks (W2S) and chronic hypobaric hypoxia group, exposing to hypobaric hypoxic condition for 4 weeks (W4S). The RNA sequencing was performed on the small intestine tissues of the three groups of rats. The results of principal component analysis showed that the W4S and W2S groups were quite different from the control group. We identified a total of 636 differentially expressed genes, such as ATP binding cassette, Ace2 and Fabp. KEGG pathway analysis identified several metabolic and digestive pathways, such as PPAR signaling pathway, glycerolipid metabolism, fat metabolism, mineral absorption and vitamin metabolism. Cogena analysis found that up-regulation of digestive and metabolic functions began from the second week of high altitude exposure. Our study highlights the critical role of metabolic and digestive pathways of the intestine in response to the hypobaric hypoxic environment, provides new aspects for the molecular effects of hypobaric hypoxic environment on intestine, and raises further questions about between the lipid metabolism disorders and inflammation.

Abstract	Molecular phylogeny based on complete plastid genomes indicates that a previously unknown but locally common bamboo from limestone areas near the border of China and Vietnam is a member of a strongly supported monophyletic Ampelocalamus (Poaceae: Bambusoideae). Hence, Ampelocalamus sinovietnamensis sp. nov. is described. It is similar to A. actinotrichus in having culm leaf sheaths with long oral setae and relatively large foliage leaf blades that are up to 4 cm wide, but is easily distinguished from the latter by its mid‐culm branch complement with one central dominant branch elongating to reiterate the culm and one to three lateral slender branches, ovate‐elliptic culm buds, glabrous culm internodes, culm leaves with densely strigose and brown papillate‐hirsute sheaths that are much longer than the internodes and shortly ciliolate inner ligules with 0.2–0.3 mm long ciliae, and foliage leaves with glabrous blades, more or less strigose sheaths and shortly ciliolate inner ligules with ca 0.1 mm long ciliae.

Abstract	Background: Intestinal ischemia-reperfusion (I/R) injury occurs in several clinical situations and after intestinal transplantation. This study aimed to examine the role of rhubarb peony decoction (RPD) in intestinal I/R injury. Methods: Different concentrations of RPD were set to treat IEC-6 and Caco-2 cells. Cell proliferation and apoptosis were measured by CCK-8 and flow cytometry assays. High-throughput transcriptome sequencing was performed on IEC-6 cells treated with hypoxia-reoxygenation (HR) or HR and RPD. Results: RPD treatment significantly promoted the proliferation of IEC-6 and Caco-2 cells and inhibited apoptosis. Sequencing results identified 109 significantly up-regulated genes and 36 significantly down-regulated genes in the RPD group. In addition, the results of western blot suggested that HR induced the expression of c-Fos, and the treatment of RPD prevented the HR-induced c- Fos expression. Importantly, knockdown of c-Fos rescued the HR-inhibited cell proliferation and HR-induced apoptosis. Conclusions: In conclusion, RPD was beneficial in protecting the survival of intestinal epithelial cells under HR stress. Furthermore, the increase in c-Fos expression after HR stress was closely related to the proliferation and apoptosis of intestinal epithelial cells.
