基于“祛邪为第一要义”从清热化湿论治新型冠状病毒肺炎

结合验案分析,基于"祛邪为第一要义"探讨新型冠状病毒肺炎从清热化湿论治的思路与方法。认为新型冠状病毒肺炎主要是属于"湿热"性质的疫病,治疗应强调清热化湿,以"祛邪为第一要义",辅以扶正。在中医祛邪与扶正理论指导下,通过宣肺平喘、通腑泻热、芳香化湿等治法,祛邪为主,肺肠合治,可以使发热减轻或消退,使大便通畅,从而截断病情进展,避免或减少危重症的发生及死亡的风险;通过清热化湿、疏肝健脾、凉血化瘀等治法,祛邪兼以扶正,肺与肝、脾合调,可以改善肝功能损伤,减少病情加重的风险;通过补气健脾等扶正治法,可以改善患者的精神和体力,促使病毒更快转阴,缩短病程,促进患者早日康复。

The prognostic relevance of histologic subtype in appendiceal adenocarcinoma

BackgroundThe aim of this population-based study was to determine the prognostic value of the histologic subtypes mucinous (MAC), non-mucinous (AC) and signet ring cell (SRCC) adenocarcinoma among patients with appendiceal cancer.Methods and materialsData from the Netherlands Cancer Registry (NCR) of patients with primary appendiceal adenocarcinomas with MAC, AC and SRCC histologic subtype, diagnosed between 2001 and 2015 were used (n = 675). To categorize patients according to the recent histopathological classification, the NCR was linked with the Dutch Pathology Registry (PALGA). Log-rank tests and Kaplan-Meier analyses were performed to estimate overall survival (OS), and the cox proportional hazards model was run to identify prognostic factors.ResultsAC was the most frequently encountered histologic subtype (50.9%), followed by MAC (35.8%) and SRCC (13.3%). In locoregional disease, histologic subtype was not a prognostic factor for OS with 5-year survival rates for patients with AC, MAC and SRCC of 60.0%, 60.5% and 69.6% respectively (p = 0.68). Metastatic disease was more common in SRCC (53.8%) than in MAC (38.8%) and AC (23.4%) (p < 0.0001). Median OS for patients with metastatic disease was 12.6, 27.7 and 18.2 months in AC, MAC and SRCC respectively (p < 0.005). MAC was associated with higher survival compared to AC (HR 0.48, 95%CI 0.34–0.69). In subanalyses, MAC was only a positive prognostic factor compared to AC in patients with peritoneal metastases (HR 0.42, 95%CI 0.28–0.62).ConclusionHistologic subtype had no prognostic relevance in locoregional or systemic metastatic disease in appendiceal adenocarcinoma. In peritoneal metastases, mucinous histologic subtype was a favorable prognostic factor, compared to non-mucinous and signet ring cell subtype.     

Strategies to improve research capacity across European general practice: The views of members of EGPRN and Wonca Europe

Background: The effectiveness of any national healthcare system is highly correlated with the strength of primary care within that system. A strong research basis is essential for a firm and vibrant primary care system. General practitioners (GPs) are at the centre of most primary care systems.

Objectives: To inform on actions required to increase research capacity in general practice, particularly in low capacity countries, we collected information from the members of the European General Practice Research Network (EGPRN) and the European World Organization of Family Doctors (Wonca).

Methods: A qualitative design including eight semi-structured interviews and two discursive workshops were undertaken with members of EGPRN and Wonca Europe. Appreciative inquiry methods were utilized. Krueger’s (1994) framework analysis approach was used to analyse the data.

Results: Research performance in general practice requires improvements in the following areas: visibility of research; knowledge acquisition; mentoring and exchange; networking and research networks; collaboration with industry, authorities and other stakeholders. Research capacity building (RCB) strategies need to be both flexible and financially supported. Leadership and collaboration are crucial.

Conclusion: Members of the GP research community see the clear need for both national and international primary care research networks to facilitate appropriate RCB interventions. These interventions should be multifaceted, responding to needs at different levels and tailored to the context where they are to be implemented.     

当归芍药散改善认知功能的研究进展

当归芍药散（danggui shaoyao san，DSS）是收录在汉代张仲景《金匮要略》中的著名方剂，原为治疗“妇人怀妊，腹中㽲痛”、“妇人腹中诸疾痛”而设，为中医健脾祛湿、养血调肝的著名方剂。临床多用于妇科疾病的治疗。近年发现当归芍药散具有神经保护作用，尤其对认知功能具有一定改善作用，其作用机制主要与调控雌激素水平、抑制氧化应激以及神经元突触等转导通路及相关信号分子有关。当归芍药散作为潜在的阿尔茨海默病及其他中枢神经退行性疾病治疗药物将日益受到关注，该文对当归芍药散化学成分和药理作用的研究进展进行综述。

目的探讨分案例分析法结合情景模拟法在急诊护理学生教学中的应用价值。方法以2016年10月-2017年10月本院纳入的46例急诊科实习护士为例展开研究,以教学方式的不同将46例急诊科实习护士分成观察组(n=23,接受案例分析法结合情景模拟法教学)和对照组(n=23,接受传统法教学),教学结束后对比分析两组急诊科实习护士的学习情况以及评判性思维能力。结果教学结束后,经考核发现,观察组实操成绩以及理论成绩均高于对照组(P <0.05);观察组寻求真相、求知欲、系统化能力以及分析能力等评判性思维能力均高于对照组(P <0.05)。结论在急诊护理学生教学中应用案例分析法结合情景模拟法进行教学,有利于急诊科实习护士掌握理论知识以及实操知识,同时还可以提高其评判性思维能力,可实现有效教学。     

A prognostic signature based on immune-related genes for cervical squamous cell carcinoma and endocervical adenocarcinoma

Cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC) is the fourth commonest female malignancy worldwide. CESC progresses in immune-microenvironment mainly composed of infiltrating immune and stromal cells. Here, we performed an integrated analysis incorporating the expression profiles from the Cancer Genome Atlas (TCGA) database and scores of immune and stromal cells calculated by Estimation of Stromal and Immune cells in Malignant Tumours using Expression data (ESTIMATE) algorithm. A two-gene signature (CD1C and CD6 genes) was established to predict the prognosis of CESC. Based on this signature, patients were divided into the high- and low-risk groups, and this signature showed good prognostic performance according to the results of Kaplan-Meier analysis and receiver operating characteristic (ROC) analysis in train set and two validation sets. A nomogram was built for evaluating the clinical applicability of this signature. In addition, based on Tumor Immune Estimation Resource (TIMER) database, 2 hub genes showed negative correlations with tumor purity and positive correlations with infiltrating levels of immune filtrating cells. What’s more, we propose new treatment strategies for the two prognostic subtypes. Low- risk patients were found presenting with a higher level of immune checkpoint molecules and showing higher immunogenicity in immunophenoscore (IPS) analysis, which indicated a better response for immunotherapy. Meanwhile, estimated by Genomics of Drug Sensitivity in Cancer (GDSC) database, the high-risk patients showed sensitive responses to five chemotherapy drugs. Finally, 10 candidate small-molecule drugs for CESC were defined. In summary, the CD1C-CD6 signature can accurately predict the prognosis of CESC.
