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.     

呼吸机自动测量气道阻断压与标准测量方法的一致性

目的 验证呼吸机自动测量的气道阻断压(airway occlusion pressure,P0.1)与标准测量方法的一致性,以及不同触发形式对自动测量结果的影响。方法 选择采用非阻断自动测量P0.1的呼吸机,分别进行模拟肺和临床试验。调节全自动自主呼吸模拟肺,模拟具有不同呼吸努力和呼吸力学特征的48种状态,应用待检测呼吸机,以压力支持通气模式为模拟肺进行通气。临床研究部分纳入15例接受压力支持通气的成年患者。两部分研究均随机交叉应用压力和流量触发,采集呼吸机自动监测的P0.1后,采用标准呼气末气道阻断法进行P0.1测量,作为标准参考值。采用Bland-Altman检验分析P0.1呼吸机监测值与标准参考值的一致性,计算残差(呼吸机监测值-标准参考值)和95%一致性区间,比较不同触发形式对残差的影响。结果 在模拟肺验证中,P0.1呼吸机监测值与标准参考值之间的残差(95%一致性区间)在压力和流量触发下分别为0.04(－0.63~0.70)和－0.54(－1.44~0.36)cmH₂O(1 cmH₂O=0.098 kPa),两者相比差异具有统计学意义(P<0.001)。临床观察获得了相似的结果,压力和流量触发时的残差(95%一致性区间)分别为－0.11(－0.73~0.52)和－0.54(－1.50~0.59)cmH₂O,差异无统计学意义(P>0.05),表明呼吸机监测值与标准参考值间存在一致性。结论 压力触发时,呼吸机非阻断法自动测量的P0.1与标准方法具有良好的一致性。而流量触发明显低估P0.1,建议自动监测时切换到压力触发。

Z‐ligustilide: A review of its pharmacokinetics and pharmacology

Z‐ligustilide is a natural benzoquinone derivative found in many widely used Chinese herbal medicines such as Angelica sinensis (Oliv.) Diels as well as Ligusticum chuanxiong Hort and so on. It has been used as a part of traditional Chinese medicine and is also present in various Chinese medicine preparations. Pharmacokinetic studies have shown that Z‐ligustilide has poor oral bioavailability in rats due to severe first‐pass metabolic reactions. New evidence suggests that Z‐ligustilide has a wide range of pharmacological properties, including anticancer, antiinflammatory, anti‐oxidant as well as neuroprotective activities and so on. The literature discussed is derived from readily accessible papers spanning the early 1970s to the end of March 2019. Information were collected from journals, books, and online searches (Google Scholar, PubMed, Science Direct, Science Citation Index Finder, Springer link, and CNKI). This review intends to provide a comprehensive overview of the pharmacokinetics and pharmacology of Z‐ligustilide in recent years, with a focus on its biological properties and mechanisms, which is of great significance for Chinese medicine.
