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.     

芦山地震5年后雅安市高血压患者心理卫生问题检出率及其影响因素

目的 了解芦山地震5年后雅安市高血压患者心理卫生问题检出率及其影响因素，为促进地震灾区高血压患者心理健康提供参考。方法 采用分层整群随机抽样方法，于2018年12月选取雅安市高血压患者800例作为研究对象。采用自编居民基本信息调查表收集患者的基本资料，采用12项一般健康问卷（GHQ-12）评定患者近期是否存在心理卫生问题，采用Logistic回归分析其影响因素。结果 回收有效问卷744份（93.00%），检出存在心理卫生问题者79例（10.62%）。单因素分析结果显示，不同婚姻状况（P?0.01）、家庭人均月收入（P=0.012）、是否接受社会救助（χ²=25.194，P?0.01）的高血压患者心理卫生问题检出率差异均有统计学意义。Logistic回归分析显示，未婚/分居/离异/丧偶（OR=3.879，P=0.015）以及接受社会救助（OR=4.705，P?0.01）是高血压患者存在心理卫生问题的危险因素。结论 雅安市高血压患者心理卫生问题检出率较低，未婚/分居/离异/丧偶者以及接受社会救助的高血压患者心理卫生问题可能更突出。     

Principles of environmentally-sustainable anaesthesia: a global consensus statement from the World Federation of Societies of Anaesthesiologists

The Earth’s mean surface temperature is already approximately 1.1°C higher than pre-industrial levels. Exceeding a mean 1.5°C rise by 2050 will make global adaptation to the consequences of climate change less possible. To protect public health, anaesthesia providers need to reduce the contribution their practice makes to global warming. We convened a Working Group of 45 anaesthesia providers with a recognised interest in sustainability, and used a three-stage modified Delphi consensus process to agree on principles of environmentally sustainable anaesthesia that are achievable worldwide. The Working Group agreed on the following three important underlying statements: patient safety should not be compromised by sustainable anaesthetic practices; high-, middle- and low-income countries should support each other appropriately in delivering sustainable healthcare (including anaesthesia); and healthcare systems should be mandated to reduce their contribution to global warming. We set out seven fundamental principles to guide anaesthesia providers in the move to environmentally sustainable practice, including: choice of medications and equipment; minimising waste and overuse of resources; and addressing environmental sustainability in anaesthetists’ education, research, quality improvement and local healthcare leadership activities. These changes are achievable with minimal material resource and financial investment, and should undergo re-evaluation and updates as better evidence is published. This paper discusses each principle individually, and directs readers towards further important references.     

基于PERK-eIF2α-CHOP通路调控巨噬细胞胆固醇稳态及冠心康含药血清干预机制研究＊

目的 观察具有益气化痰活血作用的冠心康对人单核/巨噬细胞株THP-1细胞PERK-eIF2α信号通路及相关活化转录因子（ATF）和C/EBP同源转录因子（CHOP）的影响，探究冠心康对胆固醇在巨噬细胞内质网中的代谢稳态调节及作为“脂毒”流出后异常沉积的相关作用。方法 采用100 ng·mL^-1 PMA及80 μg·mL^-1氧化低密度脂蛋白诱导THP-1细胞株，构建巨噬细胞模型，并随机分为模型组、冠心康组、辛伐他汀组、正常组。分别采用10%小牛血清及含药血清干预模型细胞72 h后收集细胞。HE染色观察巨噬细胞病理形态变化，同时进行胆固醇及脂滴含量测定。分别采用Real-time PCR及Western blot法检测各组细胞PERK、eIF2α、ATF、CHOP mRNA及蛋白的表达。结果 HE染色观察到模型组细胞内呈现较多红色脂滴，经胆固醇含量测定，明显高于正常组，脂滴含量测定与前者一致（P<0.01）。模型组细胞ATF、CHOP基因表达水平均显著升高（P<0.01）。与模型组比较，冠心康组和辛伐他汀组细胞ATF、CHOP基因表达水平均显著降低（P<0.01）。PERK磷酸化以及CHOP蛋白表达水平在冠心康和辛伐他汀干预组表现为显著下调，与模型组比较，差异具有统计学意义（P<0.05）。结论 冠心康可能通过调控PERK-eIF2α-CHOP通路相关基因及蛋白，减少泡沫细胞形成，从而减轻内质网应激，维持细胞内胆固醇稳态，减少细胞内胆固醇沉积。     

Special issue “The advance of solid tumor research in China”: Multi-omics analysis based on 1311 clear cell renal cell carcinoma samples identifies a glycolysis signature associated with prognosis and treatment response

In clear cell renal cell carcinoma (ccRCC), glycolysis is enhanced mainly because of the increased expression of key enzymes in glycolysis. Hence, the discovery of new molecular biomarkers for glycolysis may help guide and establish a precise system of diagnosis and treatment for ccRCC. Expression profiles of 1079 tumor samples of ccRCC patients (including 311 patients treated with everolimus or nivolumab) were downloaded from public databases. Proteomic profiles of 232 ccRCC samples were obtained from Fudan University Shanghai Cancer Center (FUSCC). Biological changes, tumor microenvironment and prognostic differences were explored between samples with various glycolysis characteristics. There were significant differences in CD8⁺ effector T cells, epithelial-to-mesenchymal transition and pan-fibroblast TGFb between the Low and High glyScore groups. The tumor mutation burden of the Low glyScore group was lower than that of the High glyScore group. And higher glyScore was significantly associated with worse overall survival (OS) in 768 ccRCC patients (P < .0001). External validation in FUSCC cohort also indicated that glyScore was of strong ability for predicting OS (P < .05). GlyScore may serve as a biomarker for predicting everolimus response in ccRCC patients due to its significant associations with progression-free survival (PFS). And glyScore may also predict overall survival in patients treated with nivolumab. We calculated the glyScore in ccRCC and the defined glyScore was of strong ability for predicting OS. In addition, glyScore may also serve as a biomarker for predicting PFS in patients treated with everolimus and could predict OS in patients treated with nivolumab.

超声引导下经皮肺穿刺活检术术后并发症分析

目的分析超声引导下经皮肺穿刺活检术术后并发症的相关影响因素。 方法收集2015年1月至2017年12月于西部战区总医院住院并在超声引导下行经皮肺穿刺活检术的205例患者临床资料，分析205例患者穿刺术后病理结果及并发症发生率，探讨超声引导下经皮肺穿刺活检术术后并发症的相关影响因素。 结果205例患者行超声引导下经皮肺穿刺活检术，术后并发出血8例，占3.9%(8/205)，术后发热3例，占1.46% (3/205)，为低热，且予以对症治疗后均恢复正常，无严重并发症发生。术后出血的发生率在不同性别、年龄、BMI及病灶类型的患者中无显著差异(P>0.05)，且吸烟对患者术后出血率也无显著影响(P>0.05)；但有基础疾病的患者其术后出血率更高(P＝0.005)，且病灶直径越小，术后越容易并发出血(P＝0.006)。不同性别、年龄及病灶类型对术后发热的发生率无显著影响(P>0.05)，且术后发热与吸烟史及基础疾病史无关(P>0.05)，但BMI≥24或3 cm ≤病灶直径(d)<6 cm的患者术后更易发热(P<0.05)。 结论超声引导下经皮肺穿刺活检术术后并发症发生率低(约为5.37%)，主要为出血及低热，其中术后出血主要与基础疾病史和病灶直径有关，术后发热主要与病灶直径及BMI有关。
