Impact of the COVID-19 pandemic on the hospital attendance of patients with primary cervical cancer in Heilongjiang,China

Information regarding the impact of the coronavirus disease 2019 (COVID-19) pandemic on cervical cancer in mainland China is lacking. We explored its impact on the hospital attendance of patients with primary cervical cancer. We included 1918 patients with primary cervical cancer who initially attended Harbin Medical University Cancer Hospital between January 23, 2019, and January 23, 2021. Attendance decreased by 31%, from 1135 in 2019 to 783 in 2020, mainly from January to June (𝜒² = 73.362, P < .001). The percentage of patients detected by screening decreased from 12.1% in January-June 2019 to 5.8% in January-June 2020 (𝜒² = 7.187, P = .007). Patients with stage I accounted for 28.4% in 2020 significantly lower than 36.6% in 2019 (𝜒² = 14.085, P < .001), and patients with stage III accounted for 27.1% in 2020 significantly higher than 20.5% in 2019 (𝜒² = 11.145, P < .001). Waiting time for treatment was extended from 8 days (median) in January-June and July-December 2019 to 16 days in January-June (𝜒² = 74.674, P < .001) and 12 days in July-December 2020 (𝜒² = 37.916, P < .001). Of the 179 patients who delayed treatment, 164 (91.6%) were for the reasons of the healthcare providers. Compared to 2019, the number of patients in Harbin or non-Harbin in Heilongjiang Province and outside the province decreased, and cross-regional medical treatment has been hindered. The COVID-19 pandemic has negatively impacted cervical cancer patient attendance at the initial phase. These results are solid evidence that a strategy and mechanism for the effective attendance of cervical cancer patients in response to public health emergencies is urgently needed.     

基于苗药五藤膏外敷对CIA大鼠炎性骨破坏的影响探讨苗医外治就近驱邪的作用＊

目的 通过研究明确苗药五藤膏外敷缓解胶原诱导性关节炎（CIA）大鼠关节局部炎症和骨破坏的机制，证实苗医外治就近驱邪的作用。方法 将70只Wistar大鼠随机分为空白组、模型组、苗药五藤膏高、中、低剂量组、扶他林组及IL-17阻断组，每组10只。除空白组外，其余6组均构建CIA模型，并给予相应的外敷治疗。观察大鼠一般情况，HE染色进行病理学分析，TRAP染色检测OC生成，ELISA检测各炎症因子的含量，RT-PCR和WB分别检测RANKL的基因及蛋白表达。结果 苗药五藤膏能改善CIA大鼠破骨细胞浸润及关节病理性结构，并降低RANKL蛋白、基因表达以及TNF-α、IL-1、IL-6、IL-17含量。结论 苗药五藤膏外敷剂对CIA大鼠的治疗机制可能与降低致炎因子的分泌，抑制RANKL及OC的表达相关。     

藏药细叶亚菊的质量标准研究＊

目的 建立细叶亚菊的质量标准，为其质量控制和合理开发利用提供科学参考。方法 采用性状鉴别、显微鉴别、薄层色谱法（TLC）对细叶亚菊进行定性分析；参照《中国药典》（2020年版）通则方法对细叶亚菊水分、总灰分、酸不溶性灰分、水溶性浸出物进行含量检查；利用高效液相色谱法（HPLC）测定细叶亚菊中绿原酸、异绿原酸A的含量。结果 确定了细叶亚菊的药材性状及显微特征。TLC鉴别显示，供试品（细叶亚菊药材）与对照品（绿原酸、异绿原酸A）在相应位置上均显示相同颜色的荧光斑点。13批细叶亚菊水分、总灰分、酸不溶性灰分、浸出物的含量分别为8.55%-13.07%、6.81%-12.68%、1.11%-3.53%、8.41%-11.64%；绿原酸、异绿原酸A的含量范围分别为0.072%-0.440%、0.283%-1.324%（n=3）。结论 本研究建立的方法准确稳定，可为细叶亚菊的质量控制提供参考。暂规定细叶亚菊水分不得过12.0%，总灰分不得过10.0%，酸不溶性灰分不得过2.5%，水溶性浸出物不得少于8.0%，绿原酸不得少于0.2%，异绿原酸A不得少于0.6%。     

基于中国传统运动疗法的慢性筋骨病康复模式构建思路探析＊

中国传统运动疗法作为极具特色的康养健身运动疗法，在防病治病中的宝贵价值备受国际康复医学界关注。而慢性筋骨病是骨伤科临床中的常见病、多发病与疑难杂病，临床呈现出“一大五多五高”的特征，成为当前重大的健康问题与临床防治研究课题。本文通过深入探究中国传统运动疗法特点以及其在慢性筋骨病康复中的应用原理、原则及优势作用，提出以传统运动疗法为依托，构建慢性筋骨病防病治病应用方法模式；以三因制宜为指导，构建医院-社区-团体-患者为一体的康复管理模式；以“治未病”工程为支撑，构建慢性筋骨病管理信息资源共享平台模式；为切实提高防、控、治的能力与水平找准抓手与路径，为构建慢性筋骨病康复模式提供新的思路与方向。     

多元化联合教学模式在超声引导下疼痛介入治疗中的应用

目的探讨多元化联合教学模式在超声引导下疼痛介入治疗教学中的应用效果。方法选择2018年1月至2020年12月在北京大学第三医院疼痛科进修的30名医师作为研究对象,将其分为对照组与观察组;对照组采用常规教学模式;观察组采用多元化联合教学模式,比较两组医师技能考核成绩、教学质量评分和满意度评分。结果观察组医师技能考核成绩优良率为93.3%,高于对照组的73.3%(P<0.05);观察组医师对基础理论知识掌握、临床思维能力的提高、学习兴趣的激发、疾病诊治能力的提高4个方面的评分均高于对照组(P<0.01)。结论多元化联合教学模式可促进超声引导下疼痛介入治疗技能的提高,有利于提高学员的综合临床能力。     

Aural tuberculosis at the start of the 21st century. Literature review according to SWiM guidelines. Part 2: Treatment

ObjectivesSystematic review of the scientific literature dedicated to treatment modalities and results for aural tuberculosis published since the start of the 21^st century.Material and methodsSearch of the Medline, Cochrane and Embase databases for the period 2000 - 2020. Selection of articles in English, French and Spanish devoted to clinical cases and series documenting treatment of auricular tuberculosis. Extraction of data on pre-established files documenting treatment modalities and results. Reading of articles by two authors. Analysis performed according to SWiM guidelines, evaluating cure, tuberculosis-related death, treatment-related complications, improvement in facial palsy, and hearing sequelae rates.ResultsOne hundred and twenty eight articles: 118 case reports (159 patients) and 10 cohorts (177 patients) from 42 countries were analyzed. Female/male sex ratio was 1.2 with ages ranging from 1 month to 87 years. Medical treatment consisted in 5 to 24 months’ antitubercular antibiotic treatment using 2 to 8 antibiotics. Mastoidectomy, tympanoplasty and facial nerve decompression were associated to medical treatment in 64.7%, 17.4% and 6.2% of cases, respectively. Overall rates of cure, death, treatment-related complications, facial sequelae and hearing sequelae were 96.8%, 2%, 9.5%, 35.8% and 75.5%. In case reports, BCG vaccination did not appear to protect against facial palsy and severe intracranial complications (P > 0.6). There was no significant correlation (P > 0.3) between death and the clinical variables tested, and facial nerve decompression did not appear to influence outcome for facial function (P = 0.4).ConclusionMedical treatment is very effective but not without risk of death, complications and sequelae. It is the same as for pulmonary tuberculosis. Indications for and benefit of major auricular surgery during medical treatment deserve further studies.
