健康志愿者口服冠心Ⅱ号煎剂后血清中药物化学成分变化研究

目的考察冠心Ⅱ号煎剂口服后化学成分在人血清中的存在状况。方法用3种预处理方法和2种高效液相色谱条件对健康人服用冠心Ⅱ号煎剂后含药血清进行指纹图谱分析,并与煎剂进行比较。结果煎剂、含药血清中的差异色谱峰数目分别不超过30个、10个,后者未检测到丹参素、原儿茶醛、川芎嗪和芍药苷。结论复方制剂中吸收入血的可测化学成分数目有限,其进入体内的化学成分可能“数目相对有限”;口服复方制剂后,原有的部分化学成分可能不以原形存在于血中。

清开灵注射液对SHP_(sp)出血性中风海马区兴奋性氨基酸含量的影响

本研究采用年中易感型自发性高血压大鼠（SHPsp）.观察了清开灵（QKL）注射液对出血性中风海马区兴奋性氨基酸（EAA）含量的影响，以及神经元密度和超微结构的改变。结果显示：QKL能使海马区EAA、谷氨酸、天门冬氨酸明显降低（P＜0．01）；海马CA1区神经元损伤轻,脱失减少,神经元密度计数显著升高（P＜0．01）；超微结构显示，QKL能使出血性中风造成的脑组织变性、坏死、水肿得到改善。上述结果提示，QKL能降低SHPsp出血性中风EAA的释放,起到保护神经细胞的作用。     

痰热清注射液对流感病毒FM_1感染小鼠抗病毒作用的研究

目的:研究痰热清注射液对流感病毒亚甲型鼠肺适应株(FM1)感染小鼠的抗病毒的作用。方法:采用流感病毒FM1制备小鼠肺感染模型,观察痰热清注射液对FM1感染小鼠肺组织病理形态变化、肺组织匀浆中流感病毒血凝滴度、T淋巴细胞的增殖功能以及肺组织匀浆中细胞因子γ干扰素(IFN-γ)的含量。结果:应用痰热清注射液治疗的FM1感染小鼠肺组织病理损伤与模型组比较,改善显著,而且还对肺组织匀浆中流感病毒血凝滴度具有明显的抑制作用。同时痰热清注射液还能显著增强FM1感染小鼠T淋巴细胞的功能,显著提高小鼠肺组织匀浆中IFN-γ含量。结论:痰热清注射液能改善流感病毒感染小鼠的肺组织病理损伤,对流感病毒FM1感染小鼠具有明显的抗病毒作用。痰热清注射液的抗病毒作用可能与其能够抑制病毒在细胞内的增殖,增强机体免疫功能有关。

清代名医陈念祖“重视气血”治疗月经病用药规律及特点研究

[目的]探讨研究陈念祖治疗月经病的用药规律及特点。[方法]收集陈氏《女科要旨》《南雅堂医案》《医学从众录》中治疗月经病的处方81首,构建处方数据库。运用Excel 2010与SPSS Statistics 26.0软件对高频药物进行频数和聚类分析,并结合理论分析,提炼出陈氏治疗月经病的用药规律及特点。[结果]收集的81首处方中,涉及药物共121味。≥6次的高频药物共32味,使用频数排前3位的是当归、白芍、茯苓。高频药物种类以补血药、补气药为主;四气以温性为首;五味以甘、苦、辛为主;归经以脾经为首,肝经次之,心经再次。聚类分析得出5组核心药组,涉及归脾汤、六君子汤、越鞠丸等方剂。用药特点：使气血化生而调和脾胃,畅气血运行而疏理心肝,守气血循经而调理冲任。[结论]陈氏治疗月经病以气血为核心,调和脾胃气血、调畅心肝气机、调理冲任气血,多运用补血药、补气药、理气药。     

Relationship Between Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and the Etiology of Acute Kidney Injury (AKI)

Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Since it was first recognized in December 2019, it has resulted in the ongoing worldwide pandemic. Although acute hypoxic respiratory failure (AHRF) and acute respiratory distress syndrome (ARDS) are the main features of the disease, the involvement of other organs needs to be explored. There has been a growing concern regarding the association between acute kidney injury (AKI) and poor outcomes in SARS-CoV-2 patients. Based on current observational data, AKI is the 2^nd most common cause of morbidity and mortality behind ARDS in SARS-CoV-2 patients. Angiotensin-converting enzyme 2 (ACE2) receptor has been shown to be the cornerstone of SARS-CoV-2 infection and possibly plays a significant role in the occurrence of renal injury. The pathogenesis of AKI is likely multifactorial that involves not only direct viral invasion but also dysregulated immune response in the form of cytokine storm, ischemia to kidneys, hypercoagulable state, and rhabdomyolysis, among others. We performed a literature search of the Pubmed and Google Scholar database from 1996 to 2020 using the following keywords: severe acute respiratory syndrome coronavirus 2, coronavirus disease 2019, angiotensin-converting enzyme 2 receptor, and acute kidney injury to find the most pertinent and highest-quality of evidence. Any cited references were reviewed to identify relevant literature. The purpose of this review is to discuss, explore, and summarize the relationship between AKI in SARS-CoV-2 patients, with a focus on its epidemiology, association with ACE2 receptors, and pathophysiology of AKI.     

清朝官营茶马贸易的衰亡

茶马贸易拥有悠久的历史。基于行为角度的研究,官营茶马贸易在清雍正年间走向衰弱,衰弱的原因和私茶竞争、西北地区地缘形势的改变以及茶马贸易制度等相关。茶马贸易经济行为虽然衰弱了,但茶马贸易中的思想却没有停止,在其它地区的贸易中得以延续。     

论庾信文学作品的创新

庾信是我国南北朝时期文学的集大成者。他的文学地位源于其对于文学作品的不断开拓创新。这些创新包括体制创新、主题创新、意境创新以及语言创新四方面。惟其如此,所以后人称其作品“新奇”、“清新”且有“创见”。影响庾信文学作品推陈出新的主要因素有：南北朝政权更迭和庾信个人家庭变故、庾信在南北朝文学交游甚广、南北方自然地理环境与人文景观迥然不同、南北方民族同化与融合等。
