CCPG1 involved in corneal Aspergillus fumigatus infection

AIM: To investigate whether non-canonical autophagy transport receptor cell cycle progression 1 (CCPG1) is involved in the corneal antifungal immune response. METHODS: Human corneal epithelial cells (HCECs) and human myeloid leukemia mononuclear cells (THP-1) macrophages stimulated by Aspergillus fumigatus (A. fumigatus) were used as cell models. The expression of CCPG1 mRNA was detected by qRT-PCR. Western blot was used to determine the protein expression of CCPG1 and interleukin-1β (IL-1β). The dectin-1 neutralizing antibody was used to detect the association between dectin-1 and CCPG1. Immunofluorescence was used to observe the colocalization of CCPG1 and C-type lectin-like receptor-1 (CLEC-1) in THP-1 macrophages. RESULTS: The expression of CCPG1 started to increase at 4h after infection and increased in a time-dependent manner in HCECs and THP-1 macrophages. With dectin-1 neutralizing antibody pretreatment, the expression of IL-1β was down-regulated. CCPG1 up-regulation in response to A. fumigatus infection was independent of dectin-1. Immunofluorescence showed the colocalization of CCPG1 and CLEC-1 in THP-1 macrophages. CONCLUSION: As a specific autophagy protein of non-canonical autophagy pathway, CCPG1 is involved in corneal infection with A. fumigatus.     

1401例超长住院日患者分布与影响因素分析

目的分析超长住院患者分布及影响因素,探讨减少超长住院日的措施。方法从江苏省某三甲医院病案管理系统中调取2020年1月1日-2020年12月31日134016例出院患者的住院病案首页资料,对住院时间≥30天的1401例超长住院患者的分布特征进行统计描述,采用Logistic回归模型分析超长住院日的影响因素。结果2020年全院平均住院日为7.13天,其中超长住院患者平均住院日为41.85天。超长住院患者以60岁以上年龄组最多(39.61%);出院科室主要分布在血液科(42.18%)、普通外科(11.85%)、骨科(7.49%)等;疾病类别主要为肿瘤(47.32%)、影响健康状态和与保健机构接触的因素(10.56%)、循环系统疾病(7.07%)等;多因素Logistic回归结果显示,男性(OR=1.188)、离院方式为非医嘱离院或其他(OR=2.046)和死亡病例(OR=3.362)是超长住院的危险因素。结论控制超长住院日对平均住院日影响显著,医院应加强重点人群、重点科室和重点病种管理提高诊疗管理水平,缩短平均住院日。     

艾滋病合并肺结核中的CT影像学特征和诊断价值分析

目的探讨艾滋病合并肺结核患者行胸部CT检查的影像学特征及其在疾病诊断上的价值。方法选取本院在2018年3月至2019年4月诊治的40例艾滋病合并肺结核患者作为观察组,同时选择同期入院诊治40例单纯肺结核患者作为对照组。给予两组胸部CT检查,分析影像学特征,并探讨其诊断价值。结果与对照组比较,观察组淋巴结或胸膜受累所占比较明显更高,差异有统计学意义(P<0.05);与综合检查诊断结果比较,胸部CT检查继发性肺结核、血行播散型肺结核诊断准确率分别为96.55%、91.67%,漏诊2例(5.00%);艾滋病伴肺结核患者接受胸部CT检查时,影像学特征主要表现为双肺肺叶、肺段可见明显渗出性病变,肺内纤维索条影显示明显,同时还呈现明显空洞影、斑片状影,伴有明显腋窝、纵隔淋巴结肿大及心包、胸腔积液等情况。结论胸部CT检查方式用于艾滋病伴肺结核患者诊断,能够获得明显影像学特征,有助于诊断准确率提高。     

《伤寒论》真武汤方后加减探疑

对真武汤主证后的"或咳,或小便利,或下利,或呕"四个或然证及加减方法,以及张仲景的一般药用规律进行比较分析,笔者认为其中某些或然证与加减法的用药加减原则与一般规律不相符合,提出存疑之处,意在启发临床思考。     

子宫内膜癌三维超声血管血流参数与病理学预后指标的相关性

目的探讨子宫内膜癌三维超声血管血流参数与病理学预后指标的相关性。方法选择子宫内膜良性病变患者120例(良性组)与子宫内膜癌患者120例(癌变组),所有患者给予三维超声,记录血管血流参数;采用免疫组化法检测两组病灶病理学预后指标(IGF-1、IGF-2)表达情况并进行相关性分析。结果癌变组的超声病灶形态、内膜回声、增强强度、增强均度与良性组对比差异有统计学意义(P<0.05)。癌变组的IGF-1、IGF-2表达阳性率分别为90.8%、74.2%,显著高于良性组的28.3%、36.7%。癌变组中三维超声血流分级与良性组对比差异有统计学意义(P<0.05)。在癌变组中,直线相关分析显示三维超声血流分级与IGF-1、IGF-2表达阳性率呈显著正相关性(P<0.05)。结论子宫内膜癌患者多表现为IGF-1、IGF-2的高表达,三维超声血管血流分级程度比较高,两者存在相关性,可共同影响子宫内膜癌的发生。
