蒙医陶拉布日疗法简介

被称之为蒙医传统五种疗法之首的陶拉布日（下泻）疗法在临床应用有越来越少的趋势。这主要是因为陶拉布日疗法的服药方法略繁琐所致。陶拉布日疗法服药方法有三个步骤：即下泻施治前的准备，泻药的使用和善后调理。服药前的准备又有远近之分。泻药的使用包括配方、服法、洗肠、下泻程度和辅助疗法等五个部分。陶拉布日疗法又分为峻泻剂与缓泻剂两种。缓泻剂可无需实施施治前的准备和善后调理，直接用药，不会影响患者的工作学习，所以被广泛应用于临床。     

关节镜下人工韧带重建前交叉韧带的临床初步体会

目的探讨关节镜下应用LARS人工韧带重建前交叉韧带的可行性及近期疗效. 方法用法国产LARS人工韧带对16例前交叉韧带(anterior cruciate ligament,ACL)损伤行关节镜下ACL重建术.等距点钻胫骨、股骨骨道,将肌腱拉入骨道,韧带游离部分位于关节腔内,拉紧后2枚螺钉固定韧带,合并损伤同期处理. 结果手术时间51～86 min,平均64 min.术后无滑膜炎、韧带断裂、活动明显受限等并发症.16例均随访1.5～6个月,平均3.8月.按照IKDC评分标准:术前C级6例,D级10例;术后A级6例,B级9例, C级1例(χ2=6.264,P<0.05).Lysholm膝关节功能评分术前36～76分,(63.7±7.3)分;术后86～97分,(94.8±9.6)分(t=10.356,P<0.05). 结论关节镜下LARS人工韧带重建ACL,操作简便,可使膝关节获得即时稳定性,早期康复锻炼,最大限度的防止关节功能受限,近期疗效满意.     

隐性骨折的MRI诊断

目的：探讨骨隐性骨折的MRI诊断价值。方法：对25例外伤患者均行X线平片及MRI检查，10例患者同时行CT检查，受伤部位分别为股骨髁、胫骨近端及MRI检查，10例患者同时行CT检查，受伤部位分别为股骨髁、胫骨近端及胸椎、腰椎。结果：本组25例X线平片均未见骨折征象，CT检查10例亦无明显骨折征象，仅见骨小梁结构较乱，周围软组织肿胀；MRI检查25例显示隐性骨折呈现长T1、短T2或不规则状线形异常信号，其周围可见不规则长T2骨挫伤水肿异常高信号影，均伴有周围软组织水肿的异常信号。结论：MRI能早期诊断骨隐性骨折，若患者局部症状明显，X线检查无阳性征象者行MRI检查应为最佳检查手段。     

Chromosome neighborhood composition determines translocation outcomes after exposure to high-dose radiation in primary cells

Radiation exposure is an occupational hazard for military personnel, some health care professionals, airport security screeners, and medical patients, with some individuals at risk for acute, high-dose exposures. Therefore, the biological effects of radiation, especially the potential for chromosome damage, are major occupational and health concerns. However, the biophysical mechanisms of chromosome instability subsequent to radiation-induced DNA damage are poorly understood. It is clear that interphase chromosomes occupy discrete structural and functional subnuclear domains, termed chromosome territories (CT), which may be organized into ‘neighborhoods’ comprising groups of specific CTs. We directly evaluated the relationship between chromosome positioning, neighborhood composition, and translocation partner choice in primary lymphocytes, using a cell-based system in which we could induce multiple, concentrated DNA breaks via high-dose irradiation. We critically evaluated mis-rejoining profiles and tested whether breaks occurring nearby were more likely to fuse than breaks occurring at a distance. We show that CT neighborhoods comprise heterologous chromosomes, within which inter-CT distances directly relate to translocation partner choice. These findings demonstrate that interphase chromosome arrangement is a principal factor in genomic instability outcomes in primary lymphocytes, providing a structural context for understanding the biological effects of radiation exposure, and the molecular etiology of tumor-specific translocation patterns.     

Optimizing Efforts to Promote Mental Health on College and University Campuses: Recommendations to Facilitate Usage of Services,Resources, and Supports

Public discourse and policy change: Absence of harm from increased oversight and transparency in OPO performance

The Centers for Medicare and Medicaid Services announced changes to the Final Rule for organ procurement organizations (OPOs) in November 2020, after a 23-month period of public debate. One concern among transplant stakeholders was that public focus on OPO underperformance would harm deceased donation. Using CDC-WONDER data, we studied whether donation performance dropped during the era of public debate about OPO reform (December 2018–February 2020). Overall OPO performance as measured relative to cause, age, and location-consistent deaths rose by 12.3% in 2019, compared to a median annual change of 2.5% 2009–2019. Organ recoveries exceeded seasonally adjusted forecasts by 4.2% in the first half of 2019, by 8.1% following the Executive Order issuing a mandate for OPO metric reform, and by 14.1% between the Notice of Public Rule Making and the onset of COVID-19-related systemic disruptions. We describe changes in donor phenotype in the period of increased performance; improvement was greatest for older and donation after cardiac death (DCD) donors, and among decedents who did not have a drug-related mechanism of death. In summary, performance during an era of intense public debate and proposed regulatory changes yielded 692 additional donors over expectations, and no detriment to organ donation was observed.     

牛至挥发油对小鼠腹腔巨噬细胞活性及免疫器官重量的影响

一定浓度的牛至挥发油(OVLVO)能显著提高Balb/c小鼠腹腔巨噬细胞(Mφ)形成EA和YC花环的能力,显著增强腹腔Mφ的吞噬作用,有明显的增加小鼠脾脏重量的作用,而对胸腺的重量则无显著的影响。表明OVLVO在一定浓度下不引起免疫器官萎缩并能显著提高小鼠腹腔Mφ的活性。提示OVLVO的抗感染作用与增强Mφ的功能有关。
