基于中医临床证候探讨新型冠状病毒肺炎在岭南地区的疫性特点

目的:通过分析广东省第二人民医院收治的新型冠状病毒肺炎(以下简称新冠肺炎)患者的临床资料,从中医临床证候探讨该病在岭南地区的疫性特点,更好地指导临床辨证治疗。方法:收集广东省第二人民医院收治的36例新冠肺炎患者的临床资料,其中输入病例20例,本地病例16例,分析全部病例、输入病例和本地病例的临床资料和证候特点。结果:新冠肺炎患者年龄分布较广,平均年龄45岁,以男性居多,55.56%的患者为外地输入病例,44.44%的患者为本地感染病例。全部病例证型以湿邪郁肺型和邪热壅肺型为主,分别占44.44%和38.89%;91.67%的患者呈现“湿”的病理特点,72.22%的患者呈现“热”的病理特点。其中输入病例证型以湿邪郁肺型为主,占65.00%,100%的患者呈现“湿”的病理特点,55.00%呈现“热”的病理特点;本地病例证型以邪热壅肺为主,占56.25%,93.75%的患者呈现“热”的病理特点,81.25%呈现“湿”的病理特点。结论:本次疫病在岭南地区的疫性属于以湿邪和热邪为主导的“湿热疫”,病机特点为湿热并重;输入性病例多表现为以湿邪为患的“湿疫”,有化热的趋势和倾向,病机特点为湿重于热;本地病例多表现为以热邪为主的“温热疫”,病机特点为热重于湿。此次新冠肺炎不同地区存在不同疫性的可能,辨证和治疗要遵守三因制宜的原则。

社区获得性肺炎的中西医治疗研究进展

社区获得性肺炎(Community Acquired Pneumonia,CAP)是比较常见的院外肺部炎性疾病之一,随着细菌、支原体、衣原体等多种病原体的耐药率的上升,以及病患梯度的范围增加,CAP的发病率呈逐年上升的趋势,死亡率日益增高,导致医疗资源消耗巨大。目前临床上CAP的患者主要依靠经验性治疗。正确选择抗生素、减少病原体的耐药率,优化肺部炎症疾病的医疗方案,提高CAP临床治愈率已经成为临床医生当前面临的一项重大挑战。中药制剂具有广谱抗菌、调节免疫、不易耐药、简便价廉等特点,是解决上述难题的一个很好途径。     

Nationwide Trends in Catheter-Directed Therapy Utilization for the Treatment of Lower Extremity Deep Vein Thrombosis in Medicare Beneficiaries

PurposeTo determine overall and provider specialty trends in the use of catheter-directed therapy for lower extremity deep vein thrombosis (DVT) treatment in the Medicare population.Materials and MethodsUsing data obtained from 2007–2017 Centers for Medicare & Medicaid Services 5% research identifiable files, all claims associated with acute and chronic lower extremity DVT were identified. The annual volume of 2 services—venous percutaneous transluminal thrombectomy (current procedural terminology [CPT] code 37187) and venous infusion for thrombolysis (CPT code 37201 from 2007 to 2012 and CPT code 37212 from 2013 to 2017)—was examined for trends in DVT intervention. Utilization rates based on region and the place of service were calculated. The results were further categorized based on primary operator type (radiology, cardiology, surgery, and other).ResultsThe total number of DVT interventions increased over time, with 4.27 service counts per 100,000 beneficiaries in 2007 increasing to 13.4 by 2017, a growth rate of 12.09%. Radiologists performed the majority of interventions each year, except in 2013, in which they performed 46.6% of interventions, whereas surgeons and cardiologists combined performed the other 53.4%. In 2017, radiologists performed 7.56 services per 100,000 beneficiaries, which was 56.8% of the total count, more than those performed by surgeons, cardiologists, and unspecified providers combined.ConclusionsCatheter-directed therapy is increasingly being used for the treatment of DVT, with its use undergoing a nearly 12-fold increase from 2007 to 2017 in the Medicare population. Radiologists remained the dominant provider of these services throughout the majority of study period, with a relative reduction in market share from 72% in 2007 to 57% in 2017.     

Neurovascular-modulation: A review of primary vascular responses to transcranial electrical stimulation as a mechanism of action

BackgroundThe ubiquitous vascular response to transcranial electrical stimulation (tES) has been attributed to the secondary effect of neuronal activity forming the classic neurovascular coupling. However, the current density delivered transcranially concentrates in: A) the cerebrospinal fluid of subarachnoid space where cerebral vasculature resides after reaching the dural and pial surfaces and B) across the blood-brain-barrier after reaching the brain parenchyma. Therefore, it is anticipated that tES has a primary vascular influence.ObjectivesFocused review of studies that demonstrated the direct vascular response to electrical stimulation and studies demonstrating evidence for tES-induced vascular effect in coupled neurovascular systems.ResultstES induces both primary and secondary vascular phenomena originating from four cellular elements; the first two mediating a primary vascular phenomenon mainly in the form of an immediate vasodilatory response and the latter two leading to secondary vascular effects and as parts of classic neurovascular coupling: 1) The perivascular nerves of more superficially located dural and pial arteries and medium-sized arterioles with multilayered smooth muscle cells; and 2) The endothelial lining of all vessels including microvasculature of blood-brain barrier; 3) Astrocytes; and 4) Neurons of neurovascular units.ConclusionA primary vascular effect of tES is highly suggested based on various preclinical and clinical studies. We explain how the nature of vascular response can depend on vessel anatomy (size) and physiology and be controlled by stimulation waveform. Further studies are warranted to investigate the mechanisms underlying the vascular response and its contribution to neural activity in both healthy brain and pathological conditions – recognizing many brain diseases are associated with alteration of cerebral hemodynamics and decoupling of neurovascular units.     

Concurrent conventional & high-definition transcranial direct current stimulation for treatment of schizophrenia with co-morbid obsessive-compulsive disorder: A case report

Non-invasive brain stimulation techniques such as conventional transcranial direct current stimulation (tDCS) and high definition tDCS (HD-tDCS) are increasingly being used as add-on treatment options in schizophrenia and obsessive-compulsive disorder (OCD). This is reporting of the use of a novel accelerated, symptom-specific, add-on tDCS (combining conventional and high definition) protocol in a patient with both schizophrenia and OCD. The intervention showed clinical utility by reducing both schizophrenia and OCD symptoms.
