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.

目的 探讨多参数磁共振成像对T₁高信号间隔与非T₁高信号间隔的原发性鼻腔鼻窦黑色素瘤（PSM）的鉴别价值。方法 回顾性分析经病理证实的 PSM 44例,术前均接受常规,DWI 和DCE-MRI检查。通过单因素和多因素Logistic分析评估T₁高信号间隔与非T₁高信号间隔PSM各MRI参数的差异。结果 44例PSMs 中,T₁高信号间隔PSMs 25例,非T₁高信号间隔PSMs 19例。两者在多参数MRI中,仅T₂低信号间隔,ADC值、达峰时间（Tp）及最大相对增强率（MRER）在单变量分析中差异存在统计学意义（均P<0.05）,在多因素Logistic分析中差异均无统计学意义（P均>0.05）。结论 多参数MRI对区分T₁高信号间隔与非T₁高信号间隔的PSM具有一定的指导价值,但并不能作为区分两者的独立预测指标。

Objective To evaluate the diagnostic value of multi-parameter MRI in differential diagnosis of primary sinonasal melanoma（PSM）with high- and non-high-T₁ signal septa．Methods Forty-four patients pathologically confirmed with PSMs underwent conventional,DWI and DCE-MRI examinations before operation．Univariate and multivariate Logistic analyses were used to evaluate the differences of MRI parameters between high- and non-high-T₁ signal septa in PSMs．Results Among 44 PSMs,25 cases had high T₁ signal septa and 19 cases had non-T₁ high signal septa．In multi-parameter MRI,only T₂ low signal septa,the value of ADC,peak time（TP）and maximum relative enhancement rate（MRER）were significantly different in univariate analysis（P<0.05）,but not in multivariate Logistic analysis（P>0.05）．Conclusions Multi-parameter MRI has some value in differentiating PSM with high-T₁ and non-high-T₁ signal septa,but it can not be used as an independent predictor to distinguish them．
