重症乙肝患者肝、胰组织内HBsAg、HBcAg的检测及其与糖代谢异常关系的探讨

为探讨乙型肝炎病毒 (HBV)感染患者肝、胰组织中HBV检出情况及其与糖代谢异常之间的关系 ,采用免疫组化法对 2 2例重症HBV感染伴糖代谢异常患者的尸解肝、胰组织中HBsAg、HBcAg进行检测。同时用 2 2例空腹血糖正常的HBV感染者的尸解肝、胰组织作为对照。结果 :肝病伴糖代谢异常组与对照组胰腺组织内HBV检出例数有显著性差异 (P <0 .0 5)。提示 :乙型肝炎患者胰腺组织HBV感染可能是发生肝病伴糖代谢异常的原因之一。     

左冠状动脉异常起源于肺动脉的临床分析（附5例报告）

目的：回顾分析左冠状动脉异常起源肺动脉（anomalous origin of the left coronary artery from pulmonary artery,ALCAPA）的临床表现和辅助检查,探讨其影像学征象及其原因。方法：回顾分析本院2006年4月至2008年8月共5例经手术明确诊断的ALCAPA的临床及胸片、彩色超声心动图、CT等影像资料。结果：5例心血管造影及1例冠脉CT造影均明确诊断ALCAPA,其中3例左冠主干及其分支均起源于肺动脉,诊断完全型ALcAPA,2例仅左冠分支起源于肺动脉,诊断部分型ALCAPA;所有病例经手术征实。结论：心血管造影目前仍是诊断ALCAPA的金标准,且利用64排螺旋CT进行冠脉CT造影,具有检查时间短,无创伤性,分辨率高,可以后处理等优点。

Prenatal Sonographic Abnormal Appearances of the Fetal Hyaloid Artery: From Normal Variants to Pathology

This is a case series on the abnormal sonographic appearance and outcome of the fetal hyaloid artery (HA) detected during between 1987 and 2015 at one medical center. Fifteen cases were detected during fetal anatomy scans, usually performed at 14 to 16 weeks’ gestation. Three other cases were diagnosed following referral for a second opinion. In nine fetuses, the HA regressed normally throughout pregnancy. Of them, eight neonates had normal outcomes and one had cataract at the same eye. All nine other cases ended with adverse outcomes. Failure of the HA to regress in the third trimester appears to be an indicator of congenital blindness.     

Elucidation of molecular expression associated with abnormal development and sterility caused by electron beam irradiation in Spodoptera litura (F.) (Lepidoptera: Noctuidae)

Abstract

Purpose: The objective of the present study was to elucidate the mode of indirect action of electron beam irradiation at the molecular level against a quarantine pest, Spodoptera litura (F.).

Material and methods: Electron beam irradiation (50–200?Gy) was applied to S. litura eggs, larvae, pupae, and adults, after which the feeding area, body weight, deformity of pupae and adults, ovarian development, expression levels of vitellogenin (Vg) and vitellogenin receptor (VgR) genes, and protein levels were analyzed.

Results: The amount of feeding by S. litura larvae and the synthesis level of 70?kDa storage protein significantly decreased as the electron beam dose increased. When larvae were treated with the electron beam, morphological deformities appeared in the pupae, and abnormal wing disc (AWD) expression significantly decreased. Ovarian development was completely inhibited in emerged adults that had undergone 200?Gy electron beam irradiation as pupae. Quantitative real-time PCR (qRT-PCR) assays showed significant downregulation of the Vg and VgR genes due to electron beam irradiation; whereas the synthesis level of Vg protein (190?kDa) did not decrease with time in eggs unlike in non-irradiated (control) S. litura eggs, exhibiting irradiation induced impairment of Vg functioning.

Conclusions: These findings of radiation-induced abnormal development and sterility in S. litura together with the correlated changes at the molecular level may facilitate the development of a phytosanitary strategy against this quarantine pest using electron beam irradiation.     

Perspectives on Pap Test Follow-Up Care Among Rural Appalachian Women

Approximately one- to three-quarters of women notified of abnormal Pap test results do not receive appropriate follow-up care, dramatically elevating their risk for invasive cervical cancer. We explored barriers to and facilitators of follow-up care for women in two counties in Appalachian Kentucky, where invasive cervical cancer incidence and mortality are significantly higher than the national average. In-depth interviews were conducted among 27 Appalachian women and seven local health department personnel. Those who had been told of an atypical Pap test result tended to have one of three reactions: (1) not alarmed and generally did not obtain follow-up care; (2) alarmed and obtained follow-up care; or (3) alarmed, but did not obtain care. Each of these typologies appeared to be shaped by a differing set of three categories of influences: personal factors; procedure/provider/system factors; and ecological/community factors. Recommendations to increase appropriate follow-up care included pursuing research on explanations for these typologies and developing tailored interventions specific to women in each of the response types.
