To explore the efftects of dexmedetomidine on autophagy in myocardial tissues of myocardial ischemia-reperfusion rats and NAD dependent deacetylase (SIRT1)/rapamycin target protein (mTOR) pathway proteins. 45 SPF grade male SD rats of 8 weeks old (mean weight 220 g) were randomly divided into sham-surgery group, model group, and dexmedetomidine group, with 15 rats in each group; the model group and dexmedetomidine group were used to replicate myocardial ischemia-reperfusion model. The dexmedetomidine group was infused with dexmedetomidine hydrochloride injection before modeling, while the other two groups were infused with equal amount of physiological saline. Serum myocardial injury markers creatine kinase isoenzyme (CK-MB) and troponin I (cTnI), inflammatory factors interleukin-6 (IL-6), and tumor necrosis factor - α (TNF-α) were detected before and 24 hours after reperfusion; after euthanizing rats, TTC staining was used to calculate the percentage of myocardial infarction area. qRT-PCR and Western blot were used to detect autophagy related proteins microtubule associated protein 1A/1B light chain 3 (LC3) II/I, beclin-1, and P62 proteins, SIRT1 and mTOR, too. CK-MB, cTnI, IL-6, and TNF-α levels in the model group and dexmedetomidine group before reperfusion were significantly higher than sham-surgery group, and the dexmedetomidine group was lower than model group (P<0.05); CK-MB, cTnI, IL-6, and TNF-α levels in the model group after reperfusion were higher than before reperfusion, while the dexmedetomidine group was lower than before reperfusion, what's more, the dexmedetomidine group was significantly lower than model group (P<0.05). The percentage of myocardial infarction area, expression levels of LC3 II/I, beclin-1 and P62 proteins, SIRT1 and mTOR in the model group and dexmedetomidine group were higher than those in the sham-surgery group, but the dexmedetomidine group was significantly lower than the model group (P<0.05). Myocardial ischemia-reperfusion may furtherly increase myocardial injury and inflammatory response. Pretreatment with dexmedetomidine can partially alleviate myocardial injury, inflammatory response, myocardial infarction, and autophagy, which may be related to the inhibition of SIRT1/mTOR signaling [ABSTRACT FROM AUTHOR]

任何能夠傳遞資訊的載體皆可視為符號，文字、語言、標章皆屬之。本文以「產地證明標章」為中心，分析我國自 2011 年商標法修法後，於條文設計上多「依其性質準用」一般商標的規定。基於產地證明標章在各方面皆異於一般商標，因此，在商標侵權態樣之一──淡化（dilution）之規定上，產生準用之困難。本文從產地證明標章之意義、功能為起點，透過 Saussure 符號學分析傳統混淆誤認規範與商標淡化間所侵害之法益有何不同，並提出構成「商標淡化」之要件為何。惟我國實務對於構成商標淡化之要件看法分 歧，原因在於對商標淡化保護之法益模糊不清。本文透過語言學上轉喻（metonymy）分析淡化所保護之法益，提出產地證明標章應無一般商標淡化規定之適用，並在最後以經濟學上外部性（externality）之角度，在商標法架構下提出修法建議。 Any kinds of vehicles that can convey information could be considered symbols, including words, languages and marks. This article applies semiology and linguistics to analyze the issue in new trademark law that passed in 2011, focusing on “geographical certification mark” which only roughly stipulates as that “trademarks shall apply mutatis mutandis to certification marks.” However, due to various differences between geographical certification marks and trademarks, difficulties have arisen when applying dilution articles to geographical certification marks. This article begins by examining the meaning and function of geographical certification marks, and then applies Saussure’s semiology to identify the legal interest that “likelihood of confusion” and trademark dilution aim to protect. Moreover, this article proposes a rationale to determine whether the trademark dilution occurs, and highlights several split opinions among courts which resulting from having an unclear perception of the legal interests that the dilution articles seek to protect. This article also addresses the issue by analyzing the “metonymy” from a linguistic approach and proposes the conclusion that the dilution is not applicable to geographical certification marks. Furthermore, this article suggests other mechanisms based on “externality” in economic’s concept to protect geographical certification marks under trademark law.

Background Mental illness during pregnancy has become a major public health problem in China over the recent years, and depression is the most common psychological symptom during pregnancy. Current research efforts are directed towards the therapy on prenatal depression, whereas the construction of prediction model for prenatal depression risk has been little studied. Objective To construct a simple model for predicting the risk of prenatal depression, thus providing a valuable reference for the prevention of maternal depression during pregnancy. Methods A total of 803 pregnant women attending three hospitals in Nanchong city were consecutively recruited from May 2021 to February 2022. A self-administered questionnaire was developed for the assessment of social demographic variables, obstetrical and general medical indexes and psychological status of all participants, and Self-rating Depression Scale(SDS) was utilized to screen for the presence of maternal depression. Subjects were randomly assigned into modelling group(n=635) and validation group(n=168) at the ratio of 8∶2 under simple random sampling with replacement. The candidate risk factors of maternal depression during pregnancy were screened using binary Logistic regression analysis, and the predictive model was constructed. Then the performance of the predictive model was validated using receiver operating characteristics(ROC) curve. Results ① Lack of companionship(β =-0. 692, OR=0. 501, 95% CI: 0. 289~0. 868), low mood during the last menstrual period(β=-1. 510, OR=0. 221, 95% CI：0. 074~0. 656), emotional stress during the last menstrual period(β=-1. 082, OR=0. 339, 95% CI：0. 135~0. 853), unsatisfactory relationship between mother-in-law and daughter-in-law(β=-1. 228, OR=0. 293, 95% CI：0. 141~0. 609), and indifferent generally relationship between mother-in-law and daughter-in-law(β=-0. 831, OR=0. 436, 95% CI：0. 260~0. 730) were risk factors for prenatal depression in pregnant women(P<0. 05 or 0. 01). ② Model for predicting the prenatal depression risk yielded an area under curve(AUC ) of 0. 698(95% CI: 0. 646~0. 749), the maximum Youden index was 0. 357 in modelling group with the sensitivity and specificity was 0. 606 and 0. 751, and an AUC of 0. 672(95% CI：0. 576~0. 767) and maximum Youden index of 0. 263 in validation group with the sensitivity and specificity of 0. 556 and 0. 707. Conclusion The simple model constructed in this study has good discriminant validity in predicting of the risk of prenatal depression.

[Objective] The changes of rhizosphere soil characteristics and yield of waxy sorghum with different bandwidth configurations and sorghum-soybean intercropping pattern were studied, so as to provide a scientific basis for high quality, high yield and sustainable production of waxy sorghum. [Method] The field experiments were conducted in 2021 and 2022 by using a completely randomized block design with sole cropping waxy sorghum as CK. The nutrient content of rhizosphere soil, enzyme activity and yield of waxy sorghum were studied with setting four bandwidth configurations (T1: 120 cm of bandwidth with 40 cm of narrow row spacing for waxy sorghum, 80 cm of wide row spacing for waxy sorghum, and 40 cm of spacing between waxy sorghum and soybean; T2: 130 cm of bandwidth with 50 cm of narrow row spacing for waxy sorghum, 80 cm of wide row spacing for waxy sorghum, and 40 cm of spacing between waxy sorghum and soybean; T3: 140 cm of bandwidth with 40 cm of narrow row spacing for waxy sorghum, 100 cm of wide row spacing for waxy sorghum, and 50 cm of spacing between waxy sorghum and soybean; T4: 150 cm of bandwidth with 50 cm of narrow row spacing for waxy sorghum, 100 cm of wide row spacing for waxy sorghum, and 50 cm of spacing between waxy sorghum and soybean) based on 2 rows of waxy sorghum intercropped with 1 row of soybean. [Result] Different bandwidth configurations of waxy sorghum intercropped with soybean had significant effects on the rhizosphere soil characteristics and yield of waxy sorghum. The rhizosphere soil nutrient contents, enzyme activities and yield of waxy sorghum under different strip width configurations were significantly higher than those under sole cropping waxy sorghum, and the T3 treatment showed the best performance. In 2021 and 2022, the waxy sorghum organic matter, total N, total P, total K, available N, available P and available K contents of rhizosphere soil under the T3 treatment were 69.85 and 61. 12 g/kg, 0.84 and 1.08 g/kg, 0.39 and 0.51 g/kg, 44.61 and 46.92 g/ kg, 344.58 and 266.63 mg/kg, 25.79 and 26. 16 mg/kg, and 16. 32 and 23.60 mg/kg, respectively, with a two-year average increase of 18.47%, 13.36%, 26.00%, 12.18%, 60.85%, 43.47% and 49.24%, respectively, compared with CK. The urease, polyphenol oxidase, sucrase, nitrate reductase, and catalase activities were 207.94 and 180.27 U/g, 53.43 and 70.90 U/g, 150.09 and 208.64 U/g, 0.43 and 0.40 U/g, and 48.06 and 51.38 U/g, respectively, with a two-year average increase of 49.37%, 45.61%, 76.10%, 55.81% and 18.89%, respectively, compared with CK. The yield were 6199. 18 and 6467.28 kg/hm², respectively, with a two-year average increase of 22.68% compared with CK. [Conclusion] Under the experimental conditions, the optimal bandwidth configurations of waxy sorghum intercropped with soybean was 140 cm of bandwidth with 40 cm of narrow row spacing for waxy sorghum, 100 cm of wide row spacing for waxy sorghum, and 50 cm of spacing between waxy sorghum and soybean.

The incidence of pancreatic cancer（PC）, as a highly invasive malignant tumor, is increasing both at home and abroad annually. For patients with no indication of surgical treatment, targeted therapy has obvious advantages. The biological behaviors of tumor cells such as proliferation, apoptosis and angiogenesis are regulated by the phosphatidylinositol 3 kinase（PI3K）signaling pathway, and the use of PI3K inhibitors can improve the prognosis of patients. Inhibitors of the PI3K signaling pathway include those targeting a single component and dual or multiple inhibitors. At present, PI3K-targeted inhibitors have achieved good results in clinical trials of lymphoid hematopoietic tumors and other solid tumors, but there are few studies on pancreatic cancer. For this reason, we briefly review the research progress of PI3K pathway, summarizing the new advances of inhibitors targeting PI3K signaling pathway in the treatment of pancreatic cancer.

The parent-child relationship is the first and most important interpersonal relationship that one develops, and filial piety is an important cultural value in Chinese society. The Dual Filial Piety Model (DFPM) is a proposed indigenous psychological model of Chinese filial piety, wherein the characteristics of Chinese filial piety consist of two aspects, reciprocity and authoritarianism. The DFPM has been examined in a series of empirical studies to test its arguments. However, related research on beliefs about the Chinese parent-child relation and their connection to filial piety beliefs and behaviors is still in its early stages. Chinese society is deeply influenced by Confucianism, and this has shaped beliefs about the parent-child relation. There are two types of Confucian beliefs regarding the parent-child relation, the life origin belief (LOB) and the parent-child as a united entity belief (PUB). The purpose of this study is to examine the relationship between Confucian beliefs regarding the parent-child relation and filial behaviors, and the potential mediating role of dual filial piety beliefs among them. A questionnaire survey was conducted with 220 participants, 94 male and 126 female college students. The mean age of the participants was 21.01 (SD = 1.09). Confirmatory factor analysis was used to validate the measures, and hypotheses were tested with structural equation modeling analyses. The mediating effect of dual filial piety beliefs was also tested with the bootstrap method. The results showed that: 1. LOB is positively related to caring filial behaviors, while PUB is positively related to caring filial behaviors and compliance filial behaviors simultaneously. 2. Reciprocal filial piety belief could be a mediator of the relationships between LOB and caring filial behaviors, and between PUB and caring filial behaviors. 3. Authoritarian filial piety belief could be a mediator of the relationship between BPU and compliance filial behaviors. In accordance with the results of the research, the discussion makes some suggestions for the future for constructing a parent-child theory with Chinese cultural characteristics.

[Objective] To provide theoretical basis for developing a new tomato breeding evaluation system, the endophytic bacterial communities structure in stems of tomato varieties with different fruit shapes were analyzed, the correlation between endophytic bacteria and fruit shape was explored. [ Method] B ioinformatics analysis of the endophytic bacterial community structure and related metabolic functions in stems of different fruit shapes tomatoes ( ellipsoid, flat, long and round) were analyzed using lllumina Mi Seq sequencing technology. [ Result] A total of 31 phyla,84 orders,206 orders,347 families,655 genera,1045 species,and 1660 OTUs were identified from endophytic bacteria in stems of four fruit-shaped tomato varieties. However, there was no significant differences ( P > 0. 05) on the diversity and richness indices of the endophytic bacteria between each variety. At phylum level, Chloroflexi, Actinobacteriota, Bacteroidota, Firmicutes, Proteobacteria and Actinobaciota were the dominant endophytic bacteria in stems of four different fruit shapes tomato varieties. The composition of endophytic bacteria at phylum level was quite similar among four different fruit shapes tomato varieties. However, the proponions of different endophytic bacteria at phylum level in stems of four different frnit shapes tomato varieties were difference. At genus level, Ralstonia, Pseudonocardia, Brevibacterium, Brachybactenum, Bacillus and Rlwdococcus were the common dominant endophytic bacteria in stems of four different fruit shapes tomato varieties. PICRUSt functional prediction results showed that six types of biological metabolic pathways in the primary functional layer of endophytic bacterial genes could be found in stems of tomatoes with different fruit shapes, and the metabolic pathway was the main functions of endophytic bacteria in stems of four different fruit shapes of tomatoes. Meanwhile, although the types of predicted gene in secondary functional layer were similar, but their numbers were different in stems of different fruit shapes of tomatoes. [Conclusion] Although some common dominant endophytic bacteria at genus level could be found in stems of four different Jiuit shaped tomato varieties, but their proponions also showed in different ratios. Meanwhile, some unique dominant endophytic bacteria at genus level also could be detected in four different fruit shaped tomato varieties, respectively. It suggested that the unique dominant endophytic bacteria in stems of tomatoes at genus level and their functions, could be strongly related to the fruit shapes forming processes. It also indicates that the composition of endophytic bacteria in stems of tomatoes can be used as a bio-indicator with great potential for evaluating fruit shapes. [ABSTRACT FROM AUTHOR]

BACKGROUND: Chitosan or collagen alone can improve the microvessel density in myocardial infarction area and participate in the short-term myocardial repair after myocardial infarction. Based on this research group, thermosensitive chitosan-collagen composite hydrogel was prepared, which confirmed that it had good physical and chemical properties and was suitable for myocardial tissue engineering scaffold materials. OBJECTIVE: To prepare the chitosan-collagen composite hydrogel loaded with basic fibroblast growth factor, and to analyze its physical and chemical properties, biocompatibility and prognosis in vivo after treatment of myocardial infarction in mice. METHODS: (1) Basic fibroblast growth factor was loaded in chitosan-collagen composite hydrogel and chitosan hydrogel separately, and the release efficiency of basic fibroblast growth factor in hydrogels was detected. (2) H9C2 cardiomyocytes were seeded in two hydrogels loaded with basic fibroblast growth factor, and cell proliferation was detected by CCK8 assay. (3) C57BL/6J mice model of myocardial infarction was established and randomly divided into three groups. The blank group was injected PBS into the myocardial infarction area. The control group was injected with chitosan hydrogel loaded with basic fibroblast growth factor. The experimental group was injected with chitosan-collagen composite hydrogel loaded with basic fibroblast growth factor. Echocardiography and myocardial histology were performed 28 days after operation. The experiment was approved by Ethics Committee of Shanxi Medical University. RESULTS AND CONCLUSION: (1) Compared with chitosan hydrogel, chitosan-collagen composite hydrogel could promote the release of basic fibroblast growth factor in gel. (2) Compared with the chitosan hydrogel loaded with basic fibroblast growth factor, the chitosan-collagen composite hydrogel loaded with basic fibroblast growth factor could promote the proliferation of cardiomyocytes. (3) Echocardiography showed that the left ventricular ejection fraction and the shortening rate of left ventricular short axis in the experimental group and the control group were higher than those in the blank group (P < 0.05). Left ventricular ejection fraction and the shortening rate of left ventricular short axis in the experimental group were higher than those in the control group (P < 0.05). (4) The myocardial histological observation showed that the infarct area of the experimental group and the control group was smaller than that of the blank group (P < 0.05). The infarct area wall thickness of the experimental group and the control group was larger than that of the blank group (P < 0.05). The infarct area of the experimental group was smaller than that of the control group (P < 0.05), and the infarct area wall thickness of the experimental group was larger than that of the control group (P < 0.05). (5) The results showed that the chitosan-collagen composite hydrogel loaded with basic fibroblast growth factor had good biocompatibility, and animal transplantation could significantly reduce the ventricular remodeling after myocardial infarction.

Objectives: The freespace detection is a crucial foundation for scene perception in advanced driver assistance systems. Convolutional neural network-based methods are unable to build global contextual in‑ fortmation that generate voids and interruptions in predicted results. At the same time, Transformer-based methods lack local understanding resulting in boundary misalignment and exceed. Methods: To this end, we propose a pyramid Transformer architecture with learnable deep position encoding for road freespace de‑ tection. First, the pyramid Transformer backbone is designed to extract road features from global perspec‑ tives. Second, local window attention is employed in dual-Transformer blocks to compensate for detail loss. Finally, to address the problem that traditional unlearnable position encoding ignores the spatial corre‑ lation between pixels and the real world, a learnable position encoding from deep convolutional features is constructed to solve the attention and semantic misalignment. Results: This model is tested and evaluated on KITTI road, Cityscapes, and Xiamen road datasets. The results show that our method achieves maxi‑ mum F measure of 97.53% and 98.54% in KITTI and Cityscapes, respectively. Conclusions: Our method. [ABSTRACT FROM AUTHOR]
