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 采用体外试验的方法,研究弱酸性培养对人正常食管内皮细胞（HEEC）活力的影响及潜在的调控机制。方法 细胞培养液的pH值分别设为（6.0~6.5）和（7.0~7.4）。以中性培养组为对照。利用CCK8实验,检测弱酸培养条件下,不同时间点食管内皮细胞活力的变化。采用蛋白免疫印迹法检测p38和磷酸化p38（p-p38）的表达。利用酶联免疫吸附剂测定法检测培养基上清液中IL-1β和IL-8的表达水平,并检测加入p38激酶活性抑制剂SBS 203580后两者浓度的变化。结果 弱酸环境下,细胞活力下降。培养1 h时,弱酸组细胞活力为（96.4±8.0）%,培养3 h和6 h时分别为（88.7±6.2）%和（87.7±7.4）%。细胞中p38的水平与培养基的pH值无关。弱酸培养可以促使细胞内p-p38的含量增加。基线时,弱酸组p-p38的灰度值比值为（0.37±0.02）,在培养2 h和6 h时分别为（0.64±0.09）、（0.84±0.11）,差异显著（P<0.01）。弱酸刺激诱导食管内皮细胞表达更多的IL-8和IL-1β。基线时弱酸组上清液中IL-8和IL-1β的浓度分别为（8.64±1.31）pg/mL,（3.35±0.49）pg/mL。培养6 h后,二者的浓度分别上升至（36.85±2.02）pg/mL和（19.19±1.60）pg/mL,差异显著（P<0.01）。加入SBS 203580后,IL-8和IL-1β的浓度明显下降（P<0.05）。结论 弱酸刺激可以降低食管内皮细胞的活力。p38 MAPK可能通过调控IL-8和IL-1β的表达参与该调节过程。

Objective To study the effect of weak acidic culture on the viability of normal human esophageal endothelial cells(HEEC)and the potential regulatory mechanisms. Methods The pH values of cell culture medium were set at(6. 0-6. 5)and(7. 0-7. 4),respectively. The group in neutral medium was set as control. CCK8 experiment was used to detect the change of cell viability at different time points. The expressions of p38 and phosphorylated p38(p-p38)were detected by Western Blot experiment. Enzyme linked immunosorbent assay was used to detect IL-1β and IL-8 concentration in the medium supernatant before and after adding p38 activity inhibitor(SBS 203580). Results HEEC viability was decreased under weak acidic conditions. After 1 hour of cultivation,the HEEC viability was(96. 4±8. 0)%,after 3 and 6 hours,it decreased to(88. 7±6. 2)% and(87. 7±7. 4)%,respectively. The level of p38 in cells was independent of culture medium pH values. Weak acidic stimulation could promote an increase of p-p38 in HEEC. At baseline,the gray value ratio of p-p38 in the weak acidic group was(0. 37±0. 02),and after 2 and 6 hours of culturing,it increased to(0. 64±0. 09)and(0. 84±0. 11),respectively,which differences were significant(P<0. 01). More IL-8 and IL-1β were expressed after weak acidic stimulation. At baseline,the concentrations of IL-8 and IL-1β in the medium supernatant of weak acidic group were(8. 64±1. 31)pg/mL and(3. 35±0. 49)pg/mL. After 6 hours of culturing,they increased significantly to(36. 85±2. 02)pg/mL and(19. 19±1. 60)pg/mL(P<0. 01),while the concentrations were decreased after adding SBS 203580(P<0. 05). Conclusions The HEEC viability was reduced by weak acidic stimulation,p38 MAPK may participate in the process by regulating the expression of IL-8 and IL-1β.

Objective To construct and characterize the size-variable nano-delivery system PAMAM/DOX-pep,examine its physicochemical properties and evaluate its antitumor and targeting effects in vitro. Methods Small particle size PAMAM/DOX was obtained by physically encapsulating DOX within the hydrophobic cavity of the cationic polymer PAMAM. The large size nano-delivery system(PAMAM/DOX-pep)was formed by tandem linking small size nanoparticles by MMP-2 sensitive peptide pep(CPLGVRGC)using SMCC as a cross-linker. The particle size,potential,physical and chemical properties,inhibitory effect,cell uptake and nuclear targeting effect of each nanoparticle on mouse breast cancer cells(4T1)were detected. Results The particle size of PAMAM/DOX was about 10 nm,and the drug loading rate was 23%. PAMAMAM/DOX-pep,formed after cross-linking of peptide,had a particle size of about 200 nm,which could release DOX slowly at low pH,and remained stable,safe and non-toxic in vitro for 7 days with low hemolysis rate,and its cellular uptake amount and nuclear targeting rate increased significantly after co-incubation with MMP. Conclusions Size-variable nanoparticles overcome size-induced delivery barriers to target and deliver drugs to the 4T1 nucleus,providing a new strategy for the design of nano delivery systems.

严重烧伤后患者免疫功能的失调,易导致创面感染、全身炎症反应综合征、脓毒症、感染性休克等并发症,增加患者病死率。免疫细胞功能适度的活化将有助于烧伤患者抵御外界病原体的侵袭、促进创面的愈合,但功能过度激活或者功能低下,则会引发一系列严重的后果。本文旨在归纳严重烧伤后中性粒细胞、单核/巨噬细胞、肥大细胞、NK细胞及T淋巴细胞等免疫细胞的功能变化与炎症反应之间的关系,为完善烧伤患者诊疗、减少并发症、改善预后提供新的思路。

The imbalance of immune function in severely burned patients can easily lead to wound infection,systemic inflammatory response syndrome,sepsis,septic shock and other complications,which increase the mortality of patients. Moderate activation of immune cell function will help burned patients to resist the invasion of external pathogens and promote wound healing,but excessive activation or low function can lead to a series of serious consequences. The purpose of this paper is to summarize the relationship between the functional changes of immune cells such as neutrophils,monocytes/macrophages,mast cells,NK cells,T lymphocytes and inflammatory reaction after severe burns,and to provide new ideas for improving the diagnosis and treatment of burned patients,reducing complications and improving the prognosis.
