完全型雄激素不敏感综合征2例临床特点及处理

雄激素不敏感综合征(androgen insensitivity syndrome,AIS)又称为睾丸女性化综合征(testicular feminization syndrome,TFS),是一种X连锁遗传病,是男性假两性畸形中较常见的类型,可分为完全型AIS和不完全型AIS,其原因主要是雄激素受体(androgen receptor,AR)基因的突变导致其对雄激素产生抵抗和不应答。本文回顾南京医科大学附属妇产医院2例CAIS患者的临床资料及诊疗过程,以期能进一步提高对该病的认知及诊治水平。     

改革开放以来中医药文化发展的演进与特点探析＊

中医药文化是中医药事业发展的根基和灵魂，社会主义文化建设的重要组成。本文考察改革开放40年以来中医药文化发展的演进过程，从“社会矛盾—政策方针—中医药文化发展”的中观视角，构建了中医药文化发展分析模型，发现中医药文化先后经历了资产化发展（1978年-21世纪初）、情景化发展（21世纪初-中国共产党第十八次全国代表大会（中共十八大）前后）、生态化发展（中共十八大至今）三个阶段，每个阶段中医药文化发展的策略、重点和面临的问题具有明显的不同特点。因此，本文提出以社会矛盾为导向，优化政策引导，构建中医药文化生态体系，从个人、社会和国家发展的不同层面采取多元双向发展路径，推进健康中国发展，提升文化自信，打造文化强国。     

外源性神经节苷脂相关性吉兰—巴雷综合征的发病机制及诊治研究进展

吉兰―巴雷综合征（GBS）是一种以快速进行性四肢麻木无力为特点的急性炎性脱髓鞘性多发性多神经根神经病。随着外源性神经节苷脂在临床的广泛应用，该药引起的副作用也逐渐显现，外源性神经节苷脂相关性GBS是其最严重的并发症，临床上主要表现为轴索型GBS，以四肢弛缓性瘫痪为首发症状，表现为急性、严重且快速进展的周围神经受累，较其他轴索型GBS病情重，恢复时间长，预后差。目前发病机制尚不明确。静脉注射人免疫球蛋白是其具有循证医学证据的治疗方法，目前已取代血浆置换成为GBS首选治疗方法，推荐剂量为0.4 g/（kg·d），连续静滴5 d，大剂量激素治疗的效果还有待进一步探讨。早发现、早诊断、尽早停用外源性神经节苷脂、及时应用人血免疫球蛋白冲击治疗和康复治疗，可改善预后。     

Gray platelet syndrome: Management of perioperative bleeding in redo cardiac surgery

Gray platelet syndrome (GPS) is a rare (<1/1 000 000) and inherited platelet function disorder characterized by macrothrombocytopenia, α-granule deficiency, and hemorrhages. Bleeding intensity does not correlate with platelet count nor with functional test results. We hereby describe the perioperative bleeding prevention and management of a patient with GPS requiring multiple redo cardiac surgeries.     

Searching for Serum Antibodies to Neuronal Proteins in Patients With Myalgic Encephalopathy/Chronic Fatigue Syndrome

PurposeA role for the immune system in causing myalgic encephalopathy/chronic fatigue syndrome (ME/CFS) is long suspected, but few studies have looked for specific autoantibodies that might contribute to the symptoms. Our aim was to look for evidence of antibodies to neuronal proteins in patients with ME/CSF.MethodsSera samples from 50 patients and 50 healthy individuals were sent coded to the Neuroimmunology Laboratory in Oxford. Screening for antibody binding to neuronal tissue was performed on brain tissue and neuronal cultures. Specific serum antibodies were assessed by antigen-specific cell-based assays and radioimmunoassays. After antibody testing, the associations between seropositive status and clinical data were investigated.FindingsOverall, 8 patients and 11 participants were found to have some serum immunoreactivity toward neuronal or neuromuscular junction proteins, but only 1 patient and 2 participants had specific serum antibodies. Nevertheless, seropositive status in patients with ME was associated with shorter duration since onset and a more severe disease.ImplicationsThe results indicate no overall increased frequency of antibodies to neuronal proteins in ME/CSF and no evidence of a specific antibody that might be causative or contribute to clinical features in patients. However, the association of seropositive status with shorter duration of disease and more severe symptoms suggests a possible role of antibodies at onset in some patients and should be the focus of future studies.

鼻塞式同步间歇正压通气(NIPPV)联合布地奈德雾化治疗新生儿急性呼吸窘迫综合征疾病的临床应用研究

目的:分析鼻塞式同步间歇正压通气(NIPPV)联合布地奈德雾化治疗ARDS(新生儿急性呼吸窘迫综合征)疾病的临床应用效果。方法:纳入病例是2017年5月—2019年11月收治的104例ARDS新生儿,随机平均分为两组。参照组52例采纳CPAP(持续气道正压通气通气)治疗,实验组52例采纳NIPPV+布地奈德雾化治疗,对比两组呼吸机通气时间、用氧时间、住院时间、血气指标以及并发症发生情况。结果:实验组呼吸机通气时间、用氧时间、住院时间均明显短于参照组,差异有统计学意义P<0.05;实验组治疗3 d后PaCO2明显低于参照组,实验组治疗3 d后PH以及PaO2明显高于参照组,差异有统计学意义P<0.05;实验组并发症发生率(3.85%,2/52)明显低于参照组(21.15%,11/52),差异有统计学意义P<0.05。结论:NIPPV+布地奈德雾化可有效缩短ARDS患者机械通气时间,改善血气指标,降低并发症发生率,值得借鉴。     

Ospemifene plus fractional CO2 laser: a powerful strategy to treat postmenopausal vulvar pain

Abstract

This study is a single-center, retrospective analysis of postmenopausal women presenting with dyspareunia and vulvar pain, aiming to evaluate relative effectiveness of vestibular CO₂ laser therapy as a treatment. Three monthly sessions of laser were performed to each patient and thereafter a three-months follow-up was stablished. A total number of 72 patients undergoing vestibular laser treatment were recruited from patient files in the period between 2016 and 2018. Among these, 39 women also received a concomitant treatment with ospemifene (60?mg/day) during the study period. There was a statistically significant reduction of all the symptoms in both groups up to the three month follow-up. Regarding dryness and dyspareunia, the relief tent to be more prominent in the ospemifene?+?laser group at all follow-ups and remained statistically significant at three-month follow-up. Specifically, vestibular dryness was significantly lower in the ospemifene?+?laser group compared with the laser treatment group (?87% vs???34%, respectively), and the vestibular health score started declining faster in the ospemifene?+?laser group. Although, additional research is needed to understand the mechanism of action, our data shows that a combination regimen of laser and ospemifene may improve clinical effectiveness for long-term treatment of symptoms associated with the under-recognized genitourinary syndrome of menopause.
