Epstein–Barr-virus-associated hepatitis with aplastic anemia: A case report

ABSTRACT BACKGROUND Hepatitis-associated aplastic anemia (HAAA) is a rare condition. Patients with HAAA usually present with acute hepatitis, jaundice and significantly increased transaminase. After 1–2 mo, hepatitis gradually improves, but progressive hemocytopenia, bone marrow hematopoietic failure, and severe or extremely severe aplastic anemia are manifest. Most cases of HAAA are fulminant and usually lethal if left untreated. The literature on Epstein–Barr virus (EBV)-associated HAAA is sparse. CASE SUMMARY We report a 30-year-old man who was admitted to our hospital because of pale yellow urine and skin with a simultaneous decrease in peripheral blood ternary cells. We made a diagnosis of EBV-associated HAAA. The treatment strategy for this patient included eltrombopag, an immunosuppressive regimen of rabbit anti-human thymocyte immunoglobulin, cyclosporine, and supportive care. The patient was discharged in normal physical condition after five months. A hemogram performed on follow-up revealed that he had achieved a complete response. CONCLUSION Eltrombopag plus anti-thymocyte globubin and cyclosporine may be a therapeutic option for EBV-associated HAAA.Larger studies are warranted to confirm.     

Exploring the potential of exosomes in diagnosis and drug delivery for pancreatic ductal adenocarcinoma

Pancreatic cancer (PC) is a cancer of the digestive system, and pancreatic ductal adenocarcinoma (PDAC) accounts for approximately 90% of all PC cases. Exosomes derived from PDAC (PDAC-exosomes) promote PDAC development and metastasis. Exosomes are nanoscale vesicles secreted by most cells, which can carry biologically active molecules and mediate communication and cargo transportation among cells. Recent studies have focused on transforming exosomes into good drug delivery systems (DDSs) to improve the clinical treatment of PDAC. This review considers PDAC as the main research object to introduce the role of PDAC-exosomes in PDAC development and metastasis. This review focuses on the following two themes: (a) the great potential of PDAC-exosomes as new diagnostic markers for PDAC, and (b) the transformation of exosomes into potential DDSs.     

核医学学科新增医疗服务项目定价方法研究

目的：基于以价值为基础的定价方法，计算核医学学科新增医疗服务项目镭[²²³ Ra]骨转移瘤治疗的医疗服务价格。为相关新增医疗服务项目的申报和定价打下循证基础，为合理补偿医务人员劳动价值、提升患者服务项目可及性提供依据。方法：采集2021年3—12月使用“镭核素[²²³ Ra]骨转移瘤治疗资源投入及费用数据采集表”相关数据，开展专家访谈进行系数赋值和基线对照项目确定，得到镭[²²³ Ra]骨转移瘤治疗服务各个环节的成本和新增服务的价值。结果：镭[²²³ Ra]骨转移瘤治疗服务按服务特点分为注射前评估、治疗计划、给药、给药后监测、废弃物处理与监测等环节，各环节3地平均人力耗时分别为104分钟、39分钟、25分钟、72分钟和56分钟，中位物耗成本为48.20元，3地总成本(平均人力成本+中位物耗成本)为763.68元。结合系数赋值结果和基线对比项目，得到新增项目的价值为810.19元。结论：运用基于技术难度和风险程度的价值定价理论，计算镭[²²³ Ra]骨转移瘤治疗新增医疗服务项目的服务价值，建议以价值作为服务定价依据。该定价公式和研究方法不仅可用于其他核医学学科新增服务项目的定价，还适用于现行医疗服务项目的价格动态调整，为未来学科价格工作提供方法学参考。     

基于动脉自旋标记技术的麻痹性痴呆患者脑血流量特点及其与认知障碍相关性

目的探讨麻痹性痴呆（GPI）患者脑血流量（CBF）特点及其与认知障碍的相关性。 方法纳入2018年1月至2019年12月于首都医科大学附属北京地坛医院就诊的GPI患者18例和健康体检者18例（健康对照组），采用蒙特利尔认知评估量表评定认知功能。采用磁共振动脉自旋标记技术扫描评估其各个脑区CBF，并进一步应用Spearman相关分析CBF异常区域与认知功能的相关性。 结果GPI患者蒙特利尔认知评估量表评分低于健康对照组[（16.00 ± 7.19）vs. （27.90 ± 1.21）：t =－7.853、P < 0.001）]。18例GPI患者中，头颅MRI正常5例，脑白质病变1例，脑萎缩9例，3例患者同时存在脑萎缩和脑白质病变。健康对照组头颅MRI均未见异常。GPI患者脑13、14、28、37、38、41、42、43、44、46、48、49、50、51、52、69、70、77、78、83、84、88、109、117、165、166、167、168、169、177、178、179、187、188、211、212、213、214、215、216、219、223、227、237和238区CBF显著高于健康对照组（P均< 0.001）。GPI患者认知障碍中的注意力障碍与脑69、70、77、78、166和168区CBF异常有一定的负相关性（r =－0.476、P = 0.046，r =－0.487、P = 0.034，r =－0.604、P = 0.008，r = －0.545、P = 0.019，r =－0.544、P = 0.02，r =－0.522、P = 0.026）。 结论GPI患者存在全脑血流量升高。GPI患者认知功能障碍中的注意力障碍可能与局部脑区血流量升高有一定相关性。局部CBF越高，注意力障碍越严重。这可能也是GPI发病机制之一。

Process of forgiveness in the recovery of Chinese women survivors of intimate partner violence: Empowerment,transformation, and integration

Forgiveness has been found one substantial element in the recovery for women survivors from intimate partner violence following the termination of the abusive relationship. To further investigate the details of forgiveness in this specific context, the present study explored the process of forgiveness using grounded theory. In-depth and semi-structured interviews were conducted with 25 Chinese women survivors of IPV. The findings suggest that forgiveness is a strength-based process including empowerment, transformation, and integration phases. In the empowerment phase, survivors obtain strength at the intrapersonal, behavioural, and interpersonal levels. In the transformation phase, survivors complete cognitive transformation for their IPV experiences and emotional transformation towards former partners. In the integration phase, survivors—now freed from the past—reflect upon and apply the changes they have undergone. Two trajectories in the process were found. One trajectory is going through stages sequentially and the other trajectory is experiencing back and forth between empowerment and transformation stages before moving into the integration stage. The study's findings broaden our knowledge of the strength-based forgiveness process that women survivors of IPV undergo during recovery. Practitioners and policymakers could develop programmes and policies that support forgiveness by holistically facilitating their recovery and empowerment like assistance in dealing with life difficulties and promoting their reconnection with social networks. To improve the transferability and validity of the findings, the forgiveness of survivors of IPV could be explored in a diverse sample (e.g., survivors with low educational background or live in the rural area).
