本文给出了穿甲弹对各种陶瓷块的弹道试验结果。试验采用厚背板结构,这是一项用于评估陶瓷块抗弹效益的新技术。试验中测量了弹丸在支撑陶瓷块的厚金属背板中的剩余穿深。可以看出,不同陶瓷块的抗弹效益随着归一化有效强度的增加而单调增大。这个强度参数定义为:静态和动态压缩强度的平均值与陶瓷密度的比值。本文中给出的简单分析表明:陶瓷的抗弹效益与归一化有效强度呈线性正比关系。

虽然抗微生物药已使用50多年了,但仍有许多患者死于感染。在传染病的预防、治疗方面和研制、开发作用更强、更安全、广谱的抗微生物药方面均已取得了显著的进展。在增强和恢复人体对致病性或条件致病性微生物的免疫应答方面也作了大量的工作。那么,为什么某些抗微生物药对严重感染的患者缺乏疗效?对这样一些感染我们该如何进行治疗?

Dear Editor On July 29,2021,the Israeli Ministry of Health approved the third anti-Coronavirus disease 2019(COVID-19)vaccination(3rd-BNT162b2-booster-dose),leading to a sharp daily drop in diagnosed positive COVID-19 cases and mortality rates in Israel[1].The booster dose increased severe acute respiratory syndrome coronavirus-2(SARS-CoV-2)neutralization efficiency approximately a hundred-fold compared to individuals receiving only the second dose,providing significant protection against infection[2].

目前从大量的随机对照临床试验(RCT)中已得出结论性证据:对于经历着令人痛苦的更年期症状的围绝经期和绝经后妇女,任何形式的全身HRT均可以缓解这些症状,没有其它治疗手段能产生相似效果。尽管这种证据与日俱增,但如何提供最好的临床医疗以减轻绝经症状和预防较远期的绝经后退化性疾病,仍在争论之中。当提供更年期医药时,HRT剂量和方案的个体化是基于与症状的严重程度和绝经时间相关的最低有效剂量的原则。然而,在有症状的妇女中,尚没有多少关于长期应用不同HRT方案的资料,赖以说明心血管疾病,乳腺癌和骨质疏松症基线风险的影响。在大多数病例中,个体化的处方联同生活方式的调整就可能对更年期症状、生活质量(QoL)、性问题和骨质疏松症产生最终有益的作用,罕见严重副反应。欧洲男女更年期协会(EMAS)基于最近的流行病学研究,其中不少是来自WHI中单用雌激素组的结果,支持在有症状的妇女中进行新HRT方案的研究,以提高临床中受益和风险之间的平衡,包括生活质量方面特有的信息: 并解释美国和欧洲之间在治疗模式上的传统差异,以及在BMI、生活方式和饮食习惯方面的不同所产生的影响。对于早绝经(小于45岁) 妇女,现有资料支持HRT所特有的总体益处。目前,具有骨质疏松性骨折高危险性的妇女可考虑应用较长期的全身HRT,尤其是当其它治疗措施既不恰当又疗效不佳时,因为此时收益大于风险。而对于泌尿生殖道症状,已认为长期的局部雌激素治疗可能安全和有效。

世界核心医学期刊文摘(眼科学分册) 2006年第12期 30-30页

Aim: To describe the diagnostic and therapeutic management of cytomegalovirus (CMV) anterior uveitis unassociated with retinal necrosis in immunocompetent patients. Methods: Patients referred between 2001 and 2003 for management of unilateral, chronic, recurrent uveitis associated with secondary glaucoma underwent extensive investigation including laboratory tests for herpes virus infections. Specific antiviral treatment was initiated in all cases and the level of ocular inflammation was evaluated during the follow up. Results: Five patients, three men and two women, were included. Median age was 50 years old (range 30-80 years). Anterior unilateral uveitis without iris atrophy was observed in all cases. Uveitis was chronic in three cases and recurrent in two cases. Glaucoma was observed in all patients with amedian intraocular pressure of 30 mmHg (range 22-43 mmHg). Five patients responded initially to specific anti-CMV therapy. Even though glaucoma surgery was necessary in two cases, both ocular inflammation and glaucoma were controlled in all cases. Relapses occurred in three cases after cessation of therapy, requiring prolonged maintenance therapy with valganciclovir. Conclusions: CMV infection and specific antiviral therapy should be considered in all cases of relapsing or chronic iridocyclitis and secondary glaucoma. Maintenance regimens of valganciclovir may be necessary to prevent further relapses.

Physical rehabilitation of lung transplant candidates and recipients plays an important in optimizing physical function prior to transplant and facilitating recovery of function post-transplant. As medical and surgical interventions in lung transplantation have evolved over time, there has been a demographic shift of individuals undergoing lung transplantation including older individuals, those with multiple co-morbidites, and candidates with respiratory failure requiring bridging to transplantation. These changes have an impact on the rehabilitation needs of lung transplant candidates and recipients. This review provides a practical approach to rehabilitation based on research and clinical practice at our transplant centre. It focuses on functional assessment and exercise prescription during an uncomplicated and complicated clinical course in the pre-transplant, early and late post-transplant periods. The target audience includes clinicians involved in pre- and posttransplant patient care and rehabilitation researchers.
