COVID-19, chronic inflammatory rheumatic disease and anti-rheumatic treatments

Clinical Rheumatology - Since December 2019, the pandemic caused by coronavirus disease 2019 (COVID-19) raises a real public health problem. COVID-19 appeared in Wuhan (Hubei province) in China....     

不同病理类型原发性甲状旁腺功能亢进症临床表现的比较分析

目的 分析不同病理类型甲状旁腺功能亢进（PHPT）的临床表现特点。方法 回顾性分析1958-2005年北京协和医院收治经手术病理证实的280例PHPT患者的临床资料。按病理类型分为甲状旁腺腺瘤组208例，甲状旁腺增生组52例及甲状旁腺腺癌组20例。结果 腺癌组中男性高于另外2组（P〈0．05）。增生及腺癌组中骨畸形、骨软化比例较低，增生组骨吸收、病理性骨折比例低于腺瘤组；胃肠道症状、多饮多尿及泌尿系统病变在腺癌组中高于另外2组（P均〈0．05）。血总钙（TCa）、血游离钙离子（ICa）及24h尿Ca在腺癌组显著高于腺瘤组及增生组（P均〈0．01），在腺瘤组与增生组间差异无统计学意义（P〉0．05）。出现高钙危象的比例在腺癌组显著高于另外2组（P〈0．01）。腺癌组病灶重量高于增生组，腺瘤组病灶直径小于增生组（P均〈0．05）。结论 在本组病例中，腺癌组男性比例较高，泌尿系统病变更为多见，出现高钙危象的比例显著增高，术后复发的比例较高。增生组骨骼系统病变相对较轻，其病变甲状旁腺重量低于腺癌与腺瘤组。     

脑电监测（24小时）对头痛型癫痫的诊断意义

对６０例临床疑为头痛型痛痫的患者进行２４ｈ脑电监测。结果表明：２４ｈ脑电监测对痛痫特殊类型的检出率明显高于常规ＥＥＧ。在１４例（２３．３％）有痫样放电的患者中，出现痫样放电以睡眠期多于清醒期；且睡眠周期中以ＮＲＥＭⅠ，Ⅱ期最常见。对６例（１６．２％）反复阵发出现高波幅额中线θ节律而无痫性放电的患者亦应考虑头痛型癫痫的诊断。

Bilirubin and the laboratory. Advances in the 1980s, considerations for the 1990s

The limitations of current methods of measuring bilirubin are well established and relate to the broad dynamic range and inability of the technique to determine different but structurally similar bilirubin species. New instrumentation and methodology circumvent these limitations, and clinical studies are beginning to reveal their increased diagnostic usefulness. Nevertheless, in several clinical situations, for example, the prediction of kernicterus, better bilirubin determinations may not eliminate the controversy surrounding appropriate therapeutic interventions.     

Emergency splenic arterial embolization for massive variceal bleeding in liver recipient with left-sided portal hypertension.

Splenic vein thrombosis with gastric variceal bleeding is difficult to manage, and splenectomy may be necessary to stop variceal bleeding. The authors report the case of a post-orthotopic liver transplant patient with bleeding gastric varices secondary to splenic vein thrombosis treated by partial splenic artery embolization. Successful embolization was performed via transcatheter approach depositing Gianturco coils into the intrasplenic artery resulting in immediate cessation of variceal bleeding. No recurrence of bleeding was noted postembolization. In conclusion, splenic artery embolization can be used as treatment for postliver transplant variceal bleeding with hypersplenism.     

Partial purification and osteoinductive activity of swine bone morphogenetic protein.

Bone morphogenetic protein (BMP) was isolated from the bone matrix of swine and partially purified by means of differential precipitation and molecular sieve chromatography. The molecular weight of BMP estimated by SDS-gel electrophoresis was 19,000 dalton. Bioassay by implanting two milligrams of BMP fraction into thigh muscles of mice resulted in bone formation in 100% of the experimental animals.

     

地尔硫卓联合地高辛治疗心力衰竭并慢性快速房颤分析

目的观察地尔硫卓联合小剂量地高辛对心力衰竭并慢性快速房颤患者血压、心室率和心功能的影响。方法 :心功能Ⅱ～Ⅲ级慢性房颤患者 10 6例 ,随机分为二组 ,对照组 5 0例 ,单用地高辛 ,治疗组 5 6例 ,地尔硫卓与地高辛联用 ,其余治疗二组相同 ,7～ 10d为一疗程 ,观察治疗前后血压、心率、左室射血分数 (LVEF)、心输出量 (CO)。结果 :治疗组较对照组心室率明显下降 ,控制满意 ,血压、LVEF及CO变化二组相似。结论 :地尔硫卓联合小剂量地高辛治疗心衰并慢性快速房颤患者心室率较单用地高辛效果更好 ,且较为安全。
