目的 了解广州市某三甲综合医院2016—2022年住院病例的疾病分布特征,探究新型冠状病毒感染（新冠）疫情对疾病谱的影响,为医院合理配置医疗资源、提高医院医疗水平提供参考。方法 回顾性收集广州市某三甲综合医院2016—2022年间住院病例的病例数据,按照ICD-10国际统计分类标准进行分类,建立Joinpoint回归模型对不同类别疾病构成比的时间变化趋势进行分析。结果 2016—2022年间,前12顺位的疾病种类不变,构成比呈上升趋势的有4种,分别是循环系统疾病、肿瘤、消化系统疾病以及眼和附器疾病,构成比呈下降趋势的有3种,分别是呼吸系统疾病、肌肉骨骼系统和结缔组织疾病以及妊娠、分娩和产褥期。对这7类系统疾病进行不同性别、不同年龄段和不同居住地（广州市内/市外）的亚组分析,结果显示,除眼和附器疾病与妊娠、分娩和产褥期外,其余5种系统疾病在男性和女性中变化趋势比较差异无统计学意义（均P>0.05）。25岁以上人群循环系统疾病、肿瘤和消化系统疾病比例呈上升趋势。45岁以上人群眼和附器疾病的住院比例逐年上升。呼吸系统疾病的下降趋势集中出现在0~5岁和65岁以上人群,肌肉骨骼系统和结缔组织疾病的下降趋势可在45岁以上人群中被观测到,妊娠、分娩和产褥期的下降趋势则可在45岁以下人群中被观测到。总体和市内来源的住院病例的各系统疾病构成比变化趋势均未发现有2019年的连接拐点。但对于居住地在广州市外的病例,有6种系统疾病均存在一个2019年的连接拐点,与2016—2019年相比,2020—2022年增长趋势普遍减弱或者略有降低,但均无统计学意义,2022年市外来源住院病例的多种疾病占比低于2019年。≤24岁年龄组的病例因妊娠、分娩和产褥期住院的比例在2019年以后降低趋势加快,但也无统计学意义,2020—2022年≤24岁人群因妊娠、分娩和产褥期住院的比例低于2019年水平。结论 2016—2022年期间住院病例疾病谱有较大变化,这种变化趋势在不同性别、不同年龄段和居住地间效应存在差异。2020—2022年的新冠疫情流行主要降低了居住地在广州市外的住院病例多个系统疾病的比例以及24岁及以下患者因妊娠、分娩和产褥期住院的比例。

Objective To understand the disease distribution characteristics of inpatients in a 3-A-grade general hospital in Guangzhou from 2016 to 2022,to explore the impact of the COVID-19 on the disease spectrum,and to provide reference for hospitals to reasonably allocate medical resources and improve medical level. Methods Inpatient case data of a 3-A-grade general hospital from 2016 to 2022 were retrospectively collected and were classified according to the ICD-10 international statistical classification standard. A Joinpoint regression model was established to analyze the temporal trend of disease composition ratios in different categories. Results From 2016 to 2022,the type of top 12 diseases remained unchanged. There were 4 diseases showing an upward trend in composition,namely circulatory system diseases,tumors,digestive system diseases and eye and accessory organ diseases. There were 3 diseases showing a downward trend in composition,namely respiratory system diseases,musculoskeletal system and connective tissue diseases,as well as pregnancy,childbirth and postpartum period. A subgroup analysis was conducted on these 7 types of systemic diseases by gender,age group and place of residence(within/outside Guangzhou). The results showed that except for eye and accessory organ diseases and pregnancy,childbirth and postpartum period,there was no significant difference in the trend of changes in the other 5 systemic diseases between males and females(all P>0. 05). The upward trend of circulatory system diseases,tumors and digestive system diseases could be observed in people over the age of 25. The hospitalization rate of eye and accessory organ diseases among people over 45 years old was increasing year by year. The downward trend of respiratory diseases was concentrated in people aged 0~5 and over 65 years old,while the downward trend of musculoskeletal and connective tissue diseases could be observed in people aged 45 and above. The downward trend of pregnancy,childbirth and postpartum period could be observed in people under 45 years old. The trend of changes in the proportion of systemic diseases among inpatient cases from both overall and within Guangzhou had not been found to have a joinpoint in 2019. However,for cases residing outside of Guangzhou,there were six systemic diseases that all had a joinpoint in 2019. Compared with the growth trend from 2016 to 2019,the growth trend from 2020 to 2022 generally weakened or showed a slightly downward trend,but none of them were statistically significant. In 2022,the proportion of multiple diseases in hospitalized cases from outside Guangzhou was lower than that in 2019. The proportion of cases in the age group ≤24 years old who are hospitalized due to pregnancy,childbirth and postpartum period has been decreasing rapidly since 2019,but there was no statistical significance. The proportion of cases hospitalized due to pregnancy,childbirth and postpartum period in the population ≤24 years old from 2020 to 2022 was significantly lower than the level in 2019. Conclusions The disease spectrum of inpatients had undergone significant changes between 2016 and 2022,and these trends of changes were different among different genders,age groups and places of residence. The prevalence of the COVID-19 from 2020 to 2022 mainly reduced the proportion of inpatients with multiple systemic diseases living outside Guangzhou,and the proportion of inpatients aged 24 and under hospitalized for pregnancy,childbirth and puerperium.

Objective This article aims to sort out the problems in the whole process of biosafety management and provide reference for large-scale nucleic acid screening in the future. Methods We refer to the technical guidelines and the practice of other medical institutions, combined with our practical experience, summarized the problems and solutions needing attention in biosafety management in three aspects: nucleic acid sampling place, personal protection and the process from sample collection to detection. The sampling team was strictly required to implement the standard requirements, so as to complete the screening task with quality and quantity. Results A total of 361 841 samples were collected during SARS-CoV-2 nucleic acid screening. No samples were contaminated or lost, and no biosafety accident occurred. The sampling task were successfully completed. Conclusion Large-scale SARS-CoV-2 nucleic acid screening is an important method to find out the source of the epidemic and curb the spread of the SARS-CoV-2 pandemic. In order to ensure the biosafety of the whole process, sufficient preparations should be made and biosafety measures should be strictly implemented.

目的 研究在新型冠状病毒COVID-19疫情期间,政府采取的干预措施对医院检测的流行性感冒(简称流感)阳性率的影响,为制定流感预防措施提供依据,也为间接评价新型冠状病毒的预防效果提供参考。方法 回顾性收集广州市第一人民医院总院2018—2020年年廿三至正月十五期间的流感抗原检测数据,对政府干预前后的流感抗原检测阳性率进行分析比较。结果 在春节前后,2018年和2019年的流感检测阳性率总体上维持稳定。其中,2018年春节前后,流感阳性率在15.6%～46.5%范围内波动,2019年春节前后,流感阳性率在11.9%～30.4%范围内波动。2020年同期的流感阳性率变化曲线与前两年不同,在正月初四前曲线变化较为稳定,维持在20.0%～44.1%范围内。在正月初四后曲线呈现显著下降趋势,在正月十二和正月十五,流感检测阳性率变为0。进一步的分析表明,政府干预对流感阳性率的影响无性别差异,对5～64岁人群效果最佳。结论 当前针对新型冠状病毒COVID-19的政府干预措施能显著降低流感阳性率,预防流感的发生,也为预防同样以呼吸道传播为主的新型冠状病毒的传播提供了间接证据。

Objective The aim of the study was to study the effect of government interventions on the positive rate of influenza detected in Guangzhou First People's Hospital during the outbreak of COVID-19, and to provide a basis to develop prevention measures against influenza and a reference for the indirect evaluation of the preventive effect of COVID-19. Methods Influenza antigen detection data of Guangzhou First People's Hospital were collected retrospectively from 23rd of the 12th lunar month to 15th of the 1st lunar month in 2018—2020, and the positive rates of influenza antigen detection before and after the government intervention were analyzed and compared. Results The positive rates of influenza were generally stable in 2018 and 2019 before and after the Spring Festival, where the positive rate fluctuated in the range of 15.6%～46.5% in 2018, and the positive rate fluctuates in the range of 11.9%～30.4% in 2019. The temporal change of the positive rate in 2020 was different from that of the previous two years. The positive rate curve was relatively stable before the fourth day of the first lunar month, maintaining a range of 20.0%～44.1% in 2020. After the fourth day of the first lunar month, the curve showed a significant downward trend. On the 12th and 15th day of the first lunar month, the positive rate of influenza became 0. Furthermore, the effect of government intervention on the positive rate of influenza showed no gender difference, and the effect was significant for people aged 5～64 years. Conclusion The current government intervention measures against COVID-19 could significantly reduce the positive rate of influenza, prevent the occurrence of influenza, and provide indirect evidence for the prevention of the spread of COVID-19, which was also mainly spread by respiratory tract.

The tumor types under 30 years old were leukemia, the tumor types in the 30-60 age group were colorectal cancer, and the tumor types above 60 years old were mainly lung cancer. The prognosis for patients with thyroid cancer was the best, and the prognosis for patients with pancreatic cancer was the worst. The effect of the operation group was the best. Conclusion Rational optimization of resources for screening key tumors could reduce tumor incidence and improve the quality of life of cancer cases in Guangzhou area.
