帕立骨化醇辅助西那卡塞对维持性血液透析SHPT患者FGF-23、血管钙化的影响

为了解帕立骨化醇辅助西那卡塞对维持性血液透析(MHD)继发性甲状旁腺功能亢进(SHPT)患者成纤维细胞生长因子-23(FGF-23)、血管钙化的影响。将本院血液净化中心行MHD治疗的96例SHPT患者,按照治疗方法,分为对照组(采用西那卡塞治疗)和联合组(在对照组基础上加用帕立骨化醇治疗)。比较两组患者的FGF-23、钙磷代谢、甲状旁腺激素(iPTH)及血管钙化情况。结果显示,与治疗前相比,治疗后两组患者FGF-23、血磷、钙磷积、iPTH、CACS评分、心脏瓣膜钙化率均显著降低,iPTH达标率显著升高;与对照组比较,联合组患者上述指标显著降低,但血钙水平和iPTH达标率显著升高。结果说明,帕立骨化醇辅助西那卡塞对进行MHD治疗的SHPT患者效果较好,能有效改善机体钙磷代谢,抑制血管钙化,值得临床推广应用。

Prone position combined with high-flow nasal oxygen could benefit spontaneously breathing,severe COVID-19 patients: A case report

BACKGROUNDSince the outbreak of coronavirus disease 2019 (COVID-19) in Wuhan, China in December 2019, the overall fatality rate of severe and critical patients with COVID-19 is high and the effective therapy is limited. CASE SUMMARYIn this case report, we describe a case of the successful combination of the prone position (PP) and high-flow nasal oxygen (HFNO) therapy in a spontaneously breathing, severe COVID-19 patient who presented with fever, fatigue and hypoxemia and was diagnosed by positive throat swab COVID-19 RNA testing. The therapy significantly improved the patient''s clinical symptoms, oxygenation status, and radiological characteristics of lung injury during hospitalization, and the patient showed good tolerance and avoided intubation. Additionally, we did not find that medical staff wearing optimal airborne personal protective equipment (PPE) were infected by the new coronavirus in our institution.CONCLUSIONWe conclude that the combination of PP and HFNO could benefit spontaneously breathing, severe COVID-19 patients. The therapy does not increase risk of healthcare workers wearing optimal airborne PPE to become infected with virus particles.     

Does myeloma genetic have an effect on stem cell mobilization?

BackgroundAutologous stem cell transplantation (ASCT) after induction treatment is the standard of care. Our understanding of myeloma genetics has been very limited and its effect to stem cell mobilization is not widely investigated. We aimed to investigate the effect of genetic abnormalities on stem cell mobilization in myeloma.MethodsThe data of 150 MM patients who underwent stem cell mobilization at our center between 2009–2020 were included and analyzed retrospectively. Pre-treatment bone marrow cytogenetics and fluorescence in situ hybridization tests were performed for each patient.ResultsGroups were divided into two as patients with normal cytogenetic and abnormal cytogenetic. No difference observed between groups regarding age, gender and ECOG (p = 0.4; p = 0.2; p = 0.3). Groups were similar concerning myeloma characteristics, received treatment and treatment response. Median CD34+ cells/kg harvested was 444(2−11.29) in normal cytogenetic group whereas it was 4,8(2.4−8.6) in abnormal cytogenetic group(p = 0.2). Optimal CD34+ cells level achievement was 73 (67 %) in normal cytogenetic group while it was 25(71.4 %) in abnormal cytogenetic group(p = 0.6). Neutrophil and platelet engraftment durations were similar among cytogenetic groups (p = 0.7; p = 0.9). R-ISS based groups were also did not differ regarding harvested CD34+ cells and achievement optimal CD34 level (p = 0.79, p = 0.74). Engraftment durations for neutrophil and platelet were comparable between R-ISS based groups (p = 0.59, p = 0.65)ConclusionsHere we were not able to find any impact of genetic abnormalities on stem cell mobilization in myeloma patients. Expanded studies can aid to identify the effect of particular genetic anomalies on the stem cell mobilization.     

Carbamazepine-induced immune thrombocytopenia confirmed by modified MASPAT test

A 76-year-old man suffering post-herpetic neuralgia developed severe thrombocytopenia 15 days after the administration of carbamazepine. Carbamazepine-dependent platelet antibodies were proved to be present in the patient’s serum by a modified Monoclonal Antibody Solid-phase Platelet Antibody Test (MASPAT), and the diagnosis of carbamazepine-induced immune thrombocytopenia was confirmed. For the patient, carbamazepine should be advised to be avoided permanently. The present report advocated the application of a modified MASPAT test for the detection of carbamazepine-dependent platelet antibodies.     

RFTVR术、新型光纤CO_2激光术对早期喉癌患者症状改善情况和QOL评分、VAS评分的影响
