Science and Technology Ethics Governance, How to Put Ethics First? / 中国医学伦理学

Science and technology ethics governance, how to put ethics first? The purpose of "technological innovation, ethics first" is to build an ethical soft landing mechanism for scientific and technological innovation. Researchers of science and technology ethics should start from the practice of international and domestic science and technology ethics governance, and explore the realistic way of science and technology ethics governance on the basis of understanding and thinking about the innovative culture, value orientation and operation mechanism. First of all, it should be noted that seeking technical, management and institutional solutions in the current ethical governance of science and technology may not be perfect and thorough, but operable management measures can be explored and continuously improved under the framework of mainstream scientific and technological innovation. Secondly, the co-governance of science and technology ethics needs to further explore the corresponding group co-governance epistemology facing pluralistic co-governance. Finally, the ethical governance of science and technology should pay attention to the principle of proportionality, and avoid both lax and being too strict.

Regulation of Endoplasmic Reticulum Stress and Its Targeting Role in Spinal Cord Injury / 中国生物化学与分子生物学报

Endoplasmic reticulum is one of the most important organelles in maintaining cellular homeo⁃ stasis, mainly involved in intracellular lipid synthesis, protein folding and calcium ion homeostasis. Trau⁃ ma, ischemia and hypoxia and other pathological changes can cause protein folding dysfunction in the en⁃ doplasmic reticulum, triggering endoplasmic reticulum stress (ERS). Spinal cord injury (SCI) is a com⁃ mon traumatic disease with anextremely high disability rate, which seriously affects the quality of life. There is no safe and effective clinical methods so far. Investigations have shown that ERS is one of the important pathological changes leading to cell death and neuronal dysfunction after SCI, and is closely as⁃ sociated with signaling pathways such as apoptosis, autophagy, and inflammation in neurons after SCI; however, the molecular mechanisms between ERS and SCI have not yet been thoroughly investigated. A deeper understanding and exploration of the potential molecular mechanisms associated with ERS and SCI may be the future SCI therapeutics. In this paper, we first summarized the relationship between the chan⁃ ges of ERS⁃related genes and the pathological process of SCI, Then the interrelationships between ERS and the apoptosis, inflammation, and autophagy signaling pathways after SCI were analyzed, starting from the three main modes of regulation, including unfolded protein response (UPR), endoplasmic reticulum⁃ associated degradation (ERAD), and endoplasmic reticulophagy (ER⁃phagy),Finally, we summarize the relevant drugs and application prospects of targeting ERS for SCI in recent years, which may provide a theoretical basis for targeting the ERS pathway for SCI and provide some ideas and insights for the de⁃ velopment of future therapeutic strategies after SCI.

Short-chain fatty acids ameliorate spinal cord injury recovery by regulating the balance of regulatory T cells and effector IL-17+ γδ T cells / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Spinal cord injury (SCI) causes motor, sensory, and autonomic dysfunctions. The gut microbiome has an important role in SCI, while short-chain fatty acids (SCFAs) are one of the main bioactive mediators of microbiota. In the present study, we explored the effects of oral administration of exogenous SCFAs on the recovery of locomotor function and tissue repair in SCI. Allen's method was utilized to establish an SCI model in Sprague-Dawley (SD) rats. The animals received water containing a mixture of 150 mmol/L SCFAs after SCI. After 21 d of treatment, the Basso, Beattie, and Bresnahan (BBB) score increased, the regularity index improved, and the base of support (BOS) value declined. Spinal cord tissue inflammatory infiltration was alleviated, the spinal cord necrosis cavity was reduced, and the numbers of motor neurons and Nissl bodies were elevated. Enzyme-linked immunosorbent assay (ELISA), real-time quantitative polymerase chain reaction (qPCR), and immunohistochemistry assay revealed that the expression of interleukin (IL)‍-10 increased and that of IL-17 decreased in the spinal cord. SCFAs promoted gut homeostasis, induced intestinal T cells to shift toward an anti-inflammatory phenotype, and promoted regulatory T (Treg) cells to secrete IL-10, affecting Treg cells and IL-17+ γδ T cells in the spinal cord. Furthermore, we observed that Treg cells migrated from the gut to the spinal cord region after SCI. The above findings confirm that SCFAs can regulate Treg cells in the gut and affect the balance of Treg and IL-17+ γδ T cells in the spinal cord, which inhibits the inflammatory response and promotes the motor function in SCI rats. Our findings suggest that there is a relationship among gut, spinal cord, and immune cells, and the "gut-spinal cord-immune" axis may be one of the mechanisms regulating neural repair after SCI.

Extremely low frequency magnetic exposure attenuates oxidative stress and apoptotic cell death in injured spinal cord of rats

Secondary spinal cord injury (SCI) sets on immediately after trauma which results in vascular, morphological and biochemical changes at the site of lesion. Amongst these, the crucial events such as oxidative stress and apoptosis result in spreading the injury to adjacent tissues following the initial insult. Exposure to extremely low frequency magnetic field (ELFMF) is reported to modulate oxidative stress and cell death in vivo. Here, we investigated the influence of ELFMF on oxidative stress and cell death after SCI. Adult male Wistar rats were divided into Sham-SCI (Laminectomy only), Sham-SCI+MF (ELFMF exposure; 17.96 ?T intensity, 50 Hz frequency, 2 h duration/day to Sham-SCI rats), SCI (complete transection of T13 spinal cord) and SCI+MF (ELFMF exposure to SCI rats) groups. They were sacrificed on day 2 for antioxidant assay and day 1, 2 and 3 for cell death study. The oxidative stress was assessed by antioxidant enzyme activities and the cell death was assessed by TUNEL assay and Caspase-3 immnuohistochemistry. Data revealed significant reduction in the lipid peroxidation and number of cells undergone cell death besides improvement in antioxidant levels in the spinal cord of ELFMF exposed SCI rats. These novel findings demonstrate the potential of ELFMF to attenuate oxidative stress and cell death in the early stage of secondary injury process after SCI.

Protocol paper: kainic acid excitotoxicity-induced spinal cord injury paraplegia in Sprague-Dawley rats

BACKGROUND: Excitotoxicity-induced in vivo injury models are vital to reflect the pathophysiological features of acute spinal cord injury (SCI) in humans. The duration and concentration of chemical treatment controls the extent of neuronal cell damage. The extent of injury is explained in relation to locomotor and behavioural activity. Several SCI in vivo methods have been reported and studied extensively, particularly contusion, compression, and transection models. These models depict similar pathophysiology to that in humans but are extremely expensive (contusion) and require expertise (compression). Chemical excitotoxicity-induced SCI models are simple and easy while producing similar clinical manifestations. The kainic acid (KA) excitotoxicity model is a convenient, low-cost, and highly reproducible animal model of SCI in the laboratory. The basic impactor approximately cost between 10,000 and 20,000 USD, while the kainic acid only cost between 300 and 500 USD, which is quite cheap as compared to traditional SCI method. METHODS: In this study, 0.05 mM KA was administered at dose of 10 µL/100 g body weight, at a rate of 10 µL/min, to induce spinal injury by intra-spinal injection between the T12 and T13 thoracic vertebrae. In this protocol, detailed description of a dorsal laminectomy was explained to expose the spinal cord, following intra-spinal kainic acid administration at desired location. The dose, rate and technique to administer kainic acid were explained extensively to reflect a successful paraplegia and spinal cord injury in rats. The postoperative care and complication post injury of paraplegic laboratory animals were also explained, and necessary requirements to overcome these complications were also described to help researcher. RESULTS: This injury model produced impaired hind limb locomotor function with mild seizure. Hence this protocol will help researchers to induce spinal cord injury in laboratories at extremely low cost and also will help to determine the necessary supplies, methods for producing SCI in rats and treatments designed to mitigate post-injury impairment. CONCLUSIONS: Kainic acid intra-spinal injection at the concentration of 0.05 mM, and rate 10 µL/min, is an effective method create spinal injury in rats, however more potent concentrations of kainic acid need to be studied in order to create severe spinal injuries.

Role of Inflammasomes in Inducing Neuroinflammation in Spinal Cord Injury / 中国生物化学与分子生物学报

Treatment and rehabilitation of spinal cord injury has been a major problem in the medical field‚ and little progress has been achieved in the improvement of neuronal function following injury. Secondary damage is the main cause of neurological dysfunction after spinal cord injury‚ and inflammation is the most important pathological process in the secondary injury stage. In the acute phase‚ it is believed that the reduction of secondary damage by inhibiting neuroinflammation can reduce the damage of nerve function and achieve neuroprotection. The inflammasome is a type of protein complex‚ which is assembled and named by the receptor proteins of the NLRs family and the PHYIN family of pattern recognition receptors as the main framework. Common inflammasomes include NLRP1‚ NLRP3‚ NLRC4 (IPAF)‚ and AIM2 etc. When infected or stimulated by injury‚ inflammasomes assemble in the cytoplasm and activate the pro-inflammatory protease caspase-1. Activated caspase-1 promotes the maturation and secretion of pro-inflammatory cytokines IL-1β and IL-18 on the one hand‚ and mediates pyroptosis on the other hand. Pyroptosis is a way of programmed cell death induced under pathological conditions of inflammation and stress. Cell swelling and rupture and the release of cell contents are its main characteristics. Both pro-inflammatory cytokines and intracellular substances released by pyroptosis can be used as pro-inflammatory signals to trigger an inflammatory response. Recently‚ it has been discovered that inflammasomes participate in the activation of the inflammatory cascade after spinal cord injury by inducing the release of pro-inflammatory factors and mediating pyroptosis‚ and then aggravate secondary neuroinflammation. Targeted inhibition of the activation of inflammasomes can reduce the inflammatory response‚ promote the survival of nerve cells‚ and achieve neuroprotective effects. Therefore‚ the inflammasome is expected to become a new target for the treatment of spinal cord injury. This article reviewed the structure of the inflammasome and its role in spinal cord injury‚ activation mechanism and treatment‚ which may provide ideas for the follow-up research.

Effect of Diabetes-Mediated Pericyte Injury on Blood-Spinal Cord Barrier Destruction after Spinal Cord Injury / 中国生物化学与分子生物学报

Diabetes mellitus (DM) is a common and chronic metabolic disease, which disturbs the internal environment, and then causes series of acute or chronic complications. Chronic hyperglycemia induces macroangiopathy and microangiopathy, which is synergistically regulated by intricate molecular mechanisms, including inflammatory responses, intracellular stress, pyrotosis and ferroptosis. DM hinders the repair of blood-spinal cord barrier (BSCB) after spinal cord injury (SCI) and aggravates the neurological damage. Pericytes are the main component of neurovascular units, which regulates angiogenesis, capillary blood flow, and BSCB permeability. After SCI, the BSCB is destroyed, the coverage rate of pericytes is significantly reduced. Then, it greatly affects the normal function of blood vessels. Diabetes not only plays a role in regulating the contraction phenotype and signal transduction of pericytes, but also changes the secretion genome spectrum of pericytes, and then affects the normal function of pericytes. Moreover, it has also been shown that diabetes promotes the loss of pericytes after SCI. This review systematically describes the regulatory effect of diabetes on pericytes in the vascular system, and the effect of diabetes mediated-pericyte injury on BSCB after SCI.

Analysis on the output of pharmaceutical papers and highly cited papers in Double First-rate universities / 药学实践杂志

Objective To understand the current situation of pharmaceutical research development in China and provide a constructive thinking for universities to serve the national innovation strategy through the statistical analysis of pharmaceutical papers and highly cited papers from Double First-rate universities. Methods CNKI, Wanfang, VIP and Chinese Biomedical Literature Database were searched for Chinese publications, and Scopus database was searched for English publications. Duplicates and non-research literatures were excluded. Excel 2016 software was used for statistical data analysis. Results By comparing the data from 2017 to 2019 with that from 2014 to 2016, it was found that the number of papers in Q1 area from international journals and Q2 area from domestic journals increased significantly. The popularity of publishing papers in international journals by university authors was increasing. The number of publications in domestic journals slightly decreased. From 2014 to 2020, 850 papers were published in domestic journals, among which 223 papers were highly cited, with a total cited times of 2 410 and an average cited times per publication of 10.81. Conclusion In spite of the government’s encouragement to publish the scientific and technological achievements in domestic journals, no such trend was formed from our analysis. Therefore, it is necessary to further build the corresponding academic ecology and enhance the international influence of domestic journals. The science and technology circles and technology publication circles in China should be deeply integrated to promote mutual development.

Global centennial research and the internationalization of acupuncture and moxibustion: in the perspective of SCI database (1921-2020) / 中国针灸

The paper retrieves and analyzes SCI articles on acupuncture-moxibustion published in the world from 1921 to 2020. It is found that the overall growth of SCI articles on acupuncture-moxibustion in both China and global countries is increasing, and the proportion of publication amount in China is increased gradually. It is believed that the articles on acupuncture-moxibustion researches from 1921 to 2020 in the world collected in SCI database indicate three stages, i.e. scattered publication, internationalization and great contribution on acupuncture-moxibustion in TCM. The paper investigates the first SCI article on acupuncture-moxibustion in the world and in China respectively and analyzes the main disciplines, research institutions and journal distribution, as well as the highly cited articles in the global countries. It is proposed that acupuncture-moxibustion research in China should reflect the academic ideological characteristics of acupuncture-moxibustion in TCM, develop the interdisciplinary research and deepen the cooperation with high-level scientific institutions so as to improve the international academic influence of acupuncture-moxibustion in TCM.

Reflections on the evaluation and management of SCI papers based on the category normalized citation impact: Taking a university hospital as an example / 中华医学科研管理杂志

Objective:Analyze the basic information and characteristics of SCI papers published by an institution in 2015-2019 based on the Category Normalized Citation Impact (CNCI), to provide a reference basis for SCI paper management policy improvement.Methods:Retrieve SCI papers completed by the first or correspondent unit from 2015 to 2019 from the scientific research management system of the institution. Obtain index data including journal information, impact factors, and CNCI of this group of papers from Web of science and InCites databases, and use SPSS21.0 statistical software to perform descriptive and chi-square tests.Results:The university-affiliated hospital published 3201 SCI papers from 2015-2019, with a growing trend. These papers were most frequently published in the 1<IF<3 zone, accounted for 44.92%, followed by the 3<IF<5 zone, accounted for 32.27%. These papers are mainly in Q2 journals, accounted for 31.52%, while Q1 and Q3 journals each account for 25%. From the perspective of CNCI, the average CNCI of papers in 2015-2017 was less than 1, and the average CNCI of papers in 2018-2019 was greater than 1, with no statistical difference in CNCI values between years. The proportion of high CNCIs was higher for papers with high IF. The average CNCI per page for papers in Q1 and Q2 was greater than 1, and the average CNCI per page for papers in Q3 and Q4 was less than 1. The proportion of high CNCIs was higher for papers in Q1.Conclusions:The evaluation conclusions reached under different research management perspectives are in-consistent. A comprehensive evaluation of papers based on journal divisions and CNCI is more reasonable. In a new era where indicators such as number of papers and impact factor are not the only thing that matters, it is relevant to select the top journals in the discipline and to apply comprehensive evaluation indicators such as CNCI to the evaluation of papers.

Comprehensive therapeutics targeting the corticospinal tract following spinal cord injury / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Spinal cord injury (SCI), which is much in the public eye, is still a refractory disease compromising the well-being of both patients and society. In spite of there being many methods dealing with the lesion, there is still a deficiency in comprehensive strategies covering all facets of this damage. Further, we should also mention the structure called the corticospinal tract (CST) which plays a crucial role in the motor responses of organisms, and it will be the focal point of our attention. In this review, we discuss a variety of strategies targeting different dimensions following SCI and some treatments that are especially efficacious to the CST are emphasized. Over recent decades, researchers have developed many effective tactics involving five approaches: (1) tackle more extensive regions; (2) provide a regenerative microenvironment; (3) provide a glial microenvironment; (4) transplantation; and (5) other auxiliary methods, for instance, rehabilitation training and electrical stimulation. We review the basic knowledge on this disease and correlative treatments. In addition, some well-formulated perspectives and hypotheses have been delineated. We emphasize that such a multifaceted problem needs combinatorial approaches, and we analyze some discrepancies in past studies. Finally, for the future, we present numerous brand-new latent tactics which have great promise for curbing SCI.
