Methods Retrospective analysis of the imaging and clinical data of 22 patients infected with the 2019 Novel Coronavirus (COVID-19) were reviewed, which all the patients took the X-ray or CT scan, and to record the images in the two types of inspection for each patient, including the involvement of the consolidation of the lung, ground-glass opacification, consolidation, paving stone chippings, fiber cable and interlobular septal thickening and so on. Results A total of 22 patients were diagnosed with COVID-19, and the ratio of male to female was 1:1, age range is 20~82, mean age is (52.9±16.2.21) patients received chest X-ray examination, including 3 patients received the non-contrast CT examination at the same time; 1 patient received chest CT plain examination only. 16 (76%) among the 21 patients with X-ray showed patchy and flocculent dense shadows, while the remaining 5 patients (24%) showed no abnormal signs in both lungs. 4 patients with CT scan can find the lesions. Among the 4 patients with detect CT scan, 3 patients (75%) involved 5 pulmonary lobes, and 1 patient (25%) only involved 1 pulmonary lobe. All of them showed subpleural ground-glass opacification, consolidation, paving stone chippings, fiber cable and interlobular septal thickening, including lymph node enlargement occurred in 1 case (25%), fiber strip shadows were observed in 2 cases (50%). Conclusion The imaging examination is of great value for the diagnosis and disease evaluation of COVID-19, among which X-ray examination is not good for some lesions, and CT plain scan is relatively accurate for the examination of lesions, which can be used as the preferred imaging method of COVID-19, providing further theoretical basis for early clinical diagnosis and treatment.

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.

Methods According to the data of the Guangzhou tumor case report system, a retrospective statistical analysis was performed on the basic situation, tumor location and follow-up of 23 778 tumor cases in Guangzhou First People's Hospital from 2008 to 2019. Results The top three tumors in 2008—2019 were colorectal cancer, lung cancer and liver cancer. 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.

CT imaging of the chest is characterized by patchy, ground glass high-density shadows scattered in two or one side of the lung, with uneven density, unclear boundary and significant lung field zone. Conclusion Most of the chest CT images of the patients with NCP were characterized by typical manifestations, while consolidation and pulmonary fibrosis were found in the patients with severe NCP in a short period of time.

目的 研究NR3C1(核受体亚科3,C组,成员1)又称糖皮质激素受体(GR)表达量对前列腺癌恶性程度的影响及其与前列腺癌生化复发的相关性。方法 通过组织芯片免疫组化染色检测的方法检验NR3C1在不同恶性程度前列腺癌组织的表达情况,结合Taylor数据库分析NR3C1表达水平与前列腺癌临床病理特征关系,再采用Kaplan-Meier法分析NR3C1对前列腺癌生化复发生存率的影响,最后用Cox回归分析临床病理特征与生化复发的相关性。结果 组织芯片免疫组化结果显示NR3C1在Gleason评分低的前列腺癌组织中表达高于Gleason评分高的前列腺癌组织(P=0.028)。结合Taylor公用数据库分析,NR3C1在前列腺癌组织中的表达低于癌旁组织(P＜0.001),NR3C1在Gleason评分低的前列腺癌组织中表达高于Gleason评分高的前列腺癌组织(P=0.005),NR3C1低表达与PSA复发(P=0.028)和转移(P=0.003)相关。Kaplan-Meier结果提示:NR3C1高表达组患者术后的生化复发生存率更高(P=0.043),总体生存率没有明显区别(P=0.872)。单因素分析结果显示:NR3C1(P=0.002),病理分期(P＜0.001),Gleason评分(P＜0.001),是否转移(P=0.012)是前列腺癌生化复发的影响因素。多因素分析结果显示:高Gleason 评分(P=0.017)和转移(P<0.001)均为生化复发危险因素。结论 NR3C1影响前列腺癌的发病进程,检验NR3C1的表达情况,能预测前列腺癌患者生化复发的概率,可协助判断前列腺癌预后。

Objective We study the role of NR3C1 (nuclear receptor subfamily 3,group C,member 1) in PCa progression,and the correlation between its expression level and the biochemical recurrence of PCa. Methods Immunohistochemistry was used to detect the expression of NR3C1 in PCa tissues of different degrees of malignancy. The associations of NR3C1 expression and clinical pathological features were analyzed using the Taylor dataset. Kaplan-Meier was used to detect the relationship between NR3C1 expression and biochemical recurrence survival rate in PCa. Cox-regressive analysis was used to detect the relationship between clinical pathological features and biochemical recurrence. Results Immunohistochemistry analysis showed the expression of NR3C1 was higher in which its Gleason Score was lower(P=0.028). Base on the Taylor dataset,the expression of NR3C1 was higher in the adjacent benign tissues than that in PCa(P＜0.001). The expression of NR3C1 was higher in which its Gleason Score was lower(P=0.005). Furthermore,low NR3C1 expression was associated with PSA failure(P=0.028) and Metastasis(P=0.003). Kaplan-Meier showed the biochemical recurrence-free time of PCa patients in low NR3C1 expression groups reduced(P=0.043). The overall survival time of PCa patients was not correlated to NR3C1 expression levels(P=0.872). Single factor analysis showed the biochemical recurrence is associated with NR3C1 expression(P=0.002),pathological stage(P＜0.001),Gleason score(P＜0.001), Metastasis status(P=0.012). Multivariate analysis by Cox regression further identified the high Gleason Score(P=0.017) and Metastasis status (P<0.001)were hazards of the biochemical recurrence. Conclusion Our study showed that the expression of NR3C1 critically connected with the process of PCa,which indicated that we can predict the probability of the biochemical recurrence and determine the prognosis of prostate cancer by detecting the expression of NR3C1 in PCa patients.
