网络著作权纠纷交互式审理的构建与适用--以广州互联网法院ZHI系统实践为对象

交互式审理模式是一种创新的在线审理模式,实现了从“异地同时”向“异地异时”的延伸。最高人民法院《关于人民法院在线办理案件若干问题的规定(征求意见稿)》中明确了此种审理模式。其在形式上近似于“在线书面审理模式”或“斯图加特审理模式”,但在价值追求上及适用方式上有所不同,对于司法的仪式感及审判公开原则中直接、口头、对席原则等造成的冲击,可通过扩张民事诉讼程序适用范围、限定技术的应用范围与条件等措施在一定程度上予以化解。交互式审理模式以技术为支撑,以“简案快审,高效解纷”为目标,是在繁简分流的改革试点中作出的有益探索,在提高诉讼信息沟通有效性、优化民事诉讼效益、提高数据利用效率等方面具有实践合理性。本文以广州互联网法院交互式审理案件的运用实例为分析样本,评价其功效,并对该模式在夯实技术基础、拓宽应用场景、推广模式适用等方面的发展前景予以展望。

Effects of Zhuang Gu Zhi Tong Formula on Wnt/β-catenin Osteoporosis Pathway Antagonist SOST in Osteoporosis

Objective To observe the effects of Zhuang Gu Zhi Tong Formula (ZGZTF) on antagonist SOST in canonical Wnt/β-catenin signaling pathway in osteoporosis. Methods We analyzed the differential genes of patients with osteoporosis and normal subjects from the GEO database and then found SOST with specific expression. We analyzed SOST as an antagonist of the Wnt signaling pathway by the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway. Then we studied the effect of ZGZTF on SOST in Wnt signaling pathway. Osteoporosis model was induced by ovariectomy (OVX) in 8-week-old female Sprague–Dawley (SD) rats. After 12 weeks of treatment with ZGZTF by intragastric administration, the rats were put to death in batch. The changes of alkaline phosphatase (ALP), bone gla protein (BGP) and estradiol (E2) in serum were determined, and bone mineral density (BMD) and histomorphology of right femur were observed. Biomechanics of lumbar vertebra were measured, and the expression of SOST, Wnt3a,β-catenin, LRP5, Runx2, Osx and their mRNA involving the canonical Wnt/β-catenin signaling pathway were detected by Western blot, RT-PCR and Immunohistochemical analysis. All data were analyzed by SPSS 22.0. Results Twelve weeks of treatment with ZGZTF could significantly decrease the level of ALP and BGP in serum, increase the BMD of femurs, and improve the biomechanical capability of vertebral body in maximum loading and elastic modulus. Concerning histomorphology, we found ordered arrangement of trabeculae, slightly thinning of trabeculae and none obvious slight fractures in femurs after 12 weeks of treatment with ZGZTF. The expression of LRP5,β-catenin, Runx2 and Osx involved in the canonical Wnt/β-catenin signaling pathway was significantly up-regulated in the presence of ZGZTF,and the expression of SOST in this pathway was down-regulated. Conclusions These results suggest that ZGZTF may be antiosteoporosis by down-regulating SOST protein to promote Wnt/β-catenin signaling pathway.

Molecular Biological Mechanisms of Yuan Zhi Powder in the Treatment of Alzheimer's Disease: an Analysis Based on Network Pharmacology

Objective To predict the main active ingredients,potential targets and molecular mechanisms of Yuan Zhi powder in treatment of dementia by using network pharmacology.Methods A database of chemical constituents of Yuan Zhi powder was constructed by using databases and literatures.Potential targets were predicted by reverse molecular docking,and then a component-target network was constructed.The target network of Alzheimer's disease(AD)was mapped and analyzed to obtain the“active ingredient-AD target”network.The key targets were screened through network analysis.Finally,the rationality of the prediction was analyzed by comparing with the target reported in the literatures.Results There were180chemical constituents acting on the AD target,and the targets included three key targets(cyclooxygenase-2,muscarinic acetylcholine receptor M1,and muscarinic acetylcholine receptor M2)and an important target(acetylcholine esterase).Alzheimer's disease may be treated by regulating the activity of acetylcholine receptors and the binding toβ-amyloid protein,and its biological process may be concentrated in the acetylcholine receptor signal pathway,negative regulation of synaptic transmission and so on.Conclusion The fact that Yuan Zhi powder can treat AD is consistent with the characteristics of multi-components-multitargets-multiple pathways of traditional Chinese medicine.The important targets obtained from network analysis have a large proportion in literature research,so network analysis have some rationality.

Effect of Gui Zhi decoction on enteric mucosal immune in mice with collagen-induced arthritis

AIM： To explore the effect of Gui Zhi decoction on enteric mucosal immune in type Ⅱ collagen-induced arthritis （CIA） in DBA mice. METHODS： Eighty DBA/1, weighing 18-22 g, were randomly divided into four groups with 20 in each group： control group, CIA group, treatment groups at high dosage and low dosage （GZH and GZL）. CIA was induced by immunization with type Ⅱ collagen （CII） emulsified with equal complete adjuvant at 0.1 mg CII each mouse. Blood lymphocyte suspension was screened for CD4 and CD8 expression using a flow cytometry, the CD4 and CD8 and secretory IgA （sIgA）-positive cells in enteric lamina propria tested with immunohistochemical staining. Tumor necrosis factor-alpha （TNF-α）, interleukin-1 （IL-1）-β, and IL-6 concentrations in serum were assayed with RIA. RESULTS： Gui Zhi decoction can lower the arthritic scores and decrease the occurrence of arthritis. The CD4, CD8, and sIgA-positive cells in CIA mice are less than in control mice, and in Gui Zhi decoction at high dosage could restore the lowered CD4- and CD8-positive cells in lamina propria, and at both high and low dosages could increase the lowered sIgA-positive cells in lamina propria, even still lower than in normal mice. In periphery, the CD4 cells in periphery are higher in CIA mice than in control mice, and Gui Zhi decoction at high and low dosages could decrease the CD4 and CD8 cells. Also, Gui Zhi decoction at high dosage could decrease the IL-6 and TNF-α concentration in serum. CONCLUSION： Gui Zhi decoction can lower the arthritic scores and decrease the incidence of CIA in mice, and the mechanism is in part regulating enteric mucosal immune.

Plant Regeneration from In Vitro Cultured Hypocotyl Explants of Euonymus japonicus Cu zhi

Adventitious shoots were successfully regenerated from hypocotyl explants of in vitro cultures of Euonymus japonicus Cu zhi. Hypocotyl slices were cultured on Murashige and Skoog （MS） and B5 basal medium supplemented with varied concentration of different plant growth-regulators, e.g., α-naphthaleneacetic acid （NAA） and indole-3-butyric acid （IBA） in combination with 6-benzylaminopurine （6-BA） and kinetin. The study showed that shoots could be directly regenerated from hypocotyl explants without the intervening callus phase; MS medium was more suitable for adventitious shoots regeneration. The ability of hypocotyls segments to produce shoots varied depending upon their position on the seedlings. The highest regeneration rate was obtained with hypocotyl segments near to the cotyledon cultured on MS basal medium supplemented with 1.5 mg L^-1 6-BA and 0.05 mg L^-1 NAA （63.64%）. The regenerated shoots were readily elongated on the same medium as used for multiplication and rooted on half-strength MS basal medium supplemented with 1.0 mg L^-1 IBA and 100 mg L^-1 activated carbon. After being transferred to greenhouse conditions, 96% of the plantlets were successfully acclimatized. This regeneration system is applied for genetic transformation now.

Astronomical Tables in the“Lü-li zhi”:On the Characteristics and Adoption of“Licheng”Pick-up Tables

This article discusses the development of astronomical tables in ancient China based on the calendrical chapter titled“Lü-li zhi”律曆志(Monograph on harmonics and calendrical astronomy)in official histories.After surveying various types of astral scientific tables in ancient China and their layouts,this paper discusses the characteristics and adoption of“licheng”立成tables,a specific kind of pick-up table that seems to have come into use in the Sui period(581–618)and to have been widespread from the Tang period(618–907)onward.The emergence of licheng tables relates largely to the internal development of ancient Chinese astronomy,but they were also probably inspired by auspicial tables and foreign astronomical tables.By comparing tables recorded in the“Lü-li zhi”and the existing licheng tables,we find that most licheng were deleted during the compilation of“Lü-li zhi”to reduce the number of volumes.Moreover,this paper discusses several common solutions used to compress the size of tables in“Lü-li zhi.”The adoption of licheng tables into the ancient Chinese astral sciences and the reformatting of them in“Lü-li zhi”give us a different perspective for understanding the development of ancient Chinese astronomical tables and the compilation of the calendrical portion of official histories.
