Role of macrophages in peripheral nerve injury and repair

Resident and inflammatory macrophages are essential effectors of the innate immune system. These cells provide innate immune defenses and regulate tissue and organ homeostasis. In addition to their roles in diseases such as cancer, obesity and osteoarthritis, they play vital roles in tissue repair and disease rehabilitation. Macrophages and other inflammatory cells are recruited to tissue injury sites where they promote changes in the microenvironment. Among the inflammatory cell types, only macrophages have both pro-inflammatory(M1) and anti-inflammatory(M2) actions, and M2 macrophages have four subtypes. The co-action of M1 and M2 subtypes can create a favorable microenvironment, releasing cytokines for damaged tissue repair. In this review, we discuss the activation of macrophages and their roles in severe peripheral nerve injury. We also describe the therapeutic potential of macrophages in nerve tissue engineering treatment and highlight approaches for enhancing M2 cell-mediated nerve repair and regeneration.     

Comparison of the practicability of ultrasound and spiral computed tomography in the diagnosis of colon cancer: A protocol for systematic review and meta-analysis

Background:Colon cancer is a common malignant tumor of the gastrointestinal tract. Therefore, a clear diagnosis is particularly important for the treatment of colon cancer. Ultrasound and spiral computed tomography (CT) can both be used in the diagnosis, but each has its own advantages and disadvantages, which could cause confusion in clinical choice. The purpose of this study was to systematically evaluate the practicability of spiral CT and ultrasound in the diagnosis of colon cancer.Methods:A systematic search was performed by retrieving on English databases (PubMed, Embase, Web of Science, the Cochrane Library) and Chinese databases (CNKI, Wanfang, Weipu [VIP], CBM). Besides, manually search for Google and Baidu academic of diagnostic experimental study of ultrasound and spiral CT in the diagnosis of Colon Cancer. The retrieval time limit was from the establishment of the database to October 2020. Two researchers independently extracted and evaluated the quality of the data in the included study. A meta-analysis was performed using Meta Disc1.4 and RevMan5.3 software.Results:Sensitivity, specificity, positive Likelihood ratio, negative likelihood ratio, and diagnostic odds ratio were used to determine the diagnostic efficacy of ultrasonography and helical CT in colorectal cancer.Conclusions:This study will compare the practicability of CT and ultrasound in the diagnosis of colon cancer and provide reliable evidence-based basis for clinicians to choose the appropriate or best evidence-based basis.Ethics and dissemination:The private information from individuals will not be published. This systematic review also will not involve endangering participant rights. Ethical approval is not required. The results may be published in a peer-reviewed journal or disseminated in relevant conferences.OSF Registration number:DOI 10.17605/OSF.IO/WAJHQ     

Analysis of Risk and Burden of Dysentery Associated with Floods from 2004 to 2010 in Nanning,China

This study aimed to examine the association between floods and the morbidity of dysentery and to quantify the burden of dysentery due to floods in Nanning, China. A generalized additive mixed model was conducted to assess the relationship between monthly morbidity of dysentery and floods from 2004 to 2010. The years lived with disability (YLDs) of dysentery attributable to floods were then estimated based on the WHO framework of the burden of disease study for calculating the potential impact fraction. The relative risk (RR) of floods on the morbidity of dysentery was 1.44 (95% confidence interval [CI] = 1.18–1.75). The models suggest that a potential 1-day rise in flood duration may lead to 8% (RR = 1.08, 95% CI = 1.04–1.12) increase in the morbidity of dysentery. The average attributable YLD per 1,000 of dysentery caused by floods were 0.013 in males, 0.005 in females, and 0.009 in persons. Our study confirms that floods have significantly increased the risk and the burden of dysentery in the study area. Public health action should be taken to prevent and control the potential risk of dysentery after floods. Vulnerable groups such as males and children should be paid more attention.     

刍议研究生科学道德和学风教育质量管理体系之构建

研究生科学道德和学风建设是学位与研究生教育的重要组成部分。针对近年来科学研究和学术活动中各种违背科学道德和学术规范的行为时有发生,国家教育部对研究生科学道德和学风建设日益重视,因此构建研究生的科学道德和学风教育质量管理体系具有十分重要的意义。实现研究生科学道德和学风教育质量体系的方针和目标需具备三个要素,即教育实践的模式(集主题教育、方法学习、学术实践三位一体)、有效性评价机制和绩效考核机制。此外,尚需建立体系优化机制,以适应各种内外部因素的变化,保持体系的更新和优化。

沙利度胺对鼠子宫内膜异位病灶血管生成作用的研究

目的:探讨沙利度胺(thalidomide)对子宫内膜异位症(endometriosis,EMs)病灶生长和血管生成的影响,为从抗血管途径治疗EMs提供依据.方法:将EMs患者在位子宫内膜种植于重度复合性免疫缺陷病(severe combined immunodeficiency disease, SCID)小鼠皮下,建立EMs鼠模型.接种后第3周给予治疗,治疗组(n=10)腹腔注射沙利度胺50mg/kg/d,对照组(n=10)腹腔注射等体积PBS,连用14d;每隔3d测量异位病灶体积一次;病灶组织采用免疫组化法测定病灶微血管密度(microvessel density,MVD)及血管内皮生长因子(VEGF)的表达.结果:SCID小鼠皮下种植内异症模型内膜存活率高且观察方便;治疗组病灶体积增长有缩小趋势,但与对照组相比差异无统计学意义(P＞0.05);治疗组MVD显著低于对照组(P＜0.05);治疗组和对照组VEGF的表达差异无统计学意义(P＞0.05).结论:沙利度胺对EMs异位病灶的血管生成有明显抑制作用;抑制VEGF的表达可能不是沙利度胺抑制EMs血管生成的主要原因.     

还原型谷胱甘肽联合甘草酸二铵对腹部开放伤后海水浸泡犬肝功能损伤的治疗作用

Objective To investigate effect of reduced glutathione and diammonium glycyrrhizinate on the treatment of hepatic damage in experimental dogs following open abdominal injuries coupled with seawater immersion. Methods Twenty-four dogs with open abdominal injuries were randomly divided into 3 groups: the control group (given with simple observation after 1.5 h seawater immersion); the routine treatment group (given routine care and fluid transfusion after 1.5 h seawater immersion) ; the hepatic treatment group (given routine are, fluid transfusion and hepatic treatment as well, after 1.5 h seawater immersion). Each group consisted of 8 dogs. Blood samples were taken at different time points to measure total bilirubin (TB), alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), prothromin time (PT), endotoxin, tumor necrosis factor-α(TNF-α), interleukin-6 (IL-6), and pathological examination was also made at the same time. Results For the control group, contents of TB, ALT, AST and LDH increased significantly and survival time was less than 24 hours. Contents of TB, ALT, AST and LDH of the routine treatment group also increased significantly, but survival time of all the experimental animals was mere than 24 hours. Reduced glutathione and diammonium glycyrrhizinate could reduce the extent of lesion quite significantly 12～24 hours following open abdominal injuries. Conclusions Reduced glutathione and diammonium glycyrrhizinate seemed to have good effects on the treatment and prevention against hepatic damage induced by trauma coupled with seawater immersion. It could be used as a primary means for the treatment of such kind of hepatic damage.     

Vehicle of triamcinolone acetonide is associated with retinal toxicity and transient increase of lens density

Background Intravitreal triamcinolone acetonide (TA) has been widely used as a therapeutic method for many ocular diseases, but a consensus on an appropriate safe therapeutic window of dosage for intravitreal injection, and whether vehicle of TA should be reduced or eliminated, has not yet been reached. The aim of this article is to investigate these issues.Methods Forty New Zealand white rabbits were divided into four experimental groups and one control group. Four or 25 mg TA, with vehicle either reduced or not, was injected into the vitreous cavity of rabbits in experimental groups. Rabbits in the control group received 0.2 ml intravitreal sterile saline solution. Intraocular pressures (IOP) were measured by a Tonopen tonometer. Values of lens density were measured by a Pentacam system. Soluble protein, total antioxidation capacity, reduced glutathione (GSH), glutathion peroxidase (GSH-px), and superoxide dismutase (SOD) in lens were measured by specific kits. ERG and pathological examinations, including light and electron microscopy of the retina, were also performed.Results Elevation of IOP was noted in all experimental groups after intravitreal TA (P<0.01, paired t-test). Significant increase of lens density was noticed at 1 week after intravitreal TA in the 25 mg vehicle-containing group (P<0.0001, paired t-test). Significant loss of GSH-px activity was noticed at the end of the study (P<0.05, paired t-test), while SOD activity increased (P<0.05, paired t-test). Amplitudes of ERG waves declined significantly in vehicle-containing groups (P<0.01, paired t-test) at the end of the study. Pathological examination showed obvious retinal toxicity in vehicle-containing groups.Conclusions Vehicle of TA should be eliminated or reduced before intravitreal injection to avoid potential retinal toxicity and transient increase in lens density.Presented at Chinese Academy of Fundus Disease Meeting, April, 2005.This study was supported by the 985 Fund of Peking University, Beijing.The authors have no financial interest in any instruments or drugs mentioned in this study.
