流式细胞术的培训实践及技术平台建设探讨

流式细胞分析技术(flow cytometry,FCM),又称流式细胞术,是一种在功能水平上对单细胞或其他生物粒子进行定量分析和分选的技术,具有广泛的科研应用价值.采用理论与实践并举,结合讨论的教学方式,在教师队伍开设针对性的培训课程,对深刻理解并在科研工作中有效利用该技术具有及其重要意义.同时以教学促科研,以科研促技...     

Genital psoriasis: a questionnaire‐based survey on a concealed skin disease in the Netherlands

Background Psoriatic lesions may involve nearly all sites of the body. Involvement of the genital skin is frequently classified as part of intertriginous psoriasis without special awareness and treatment for this presentation of the disease. Gaining knowledge about the frequency of the involvement of genital skin in these patients will improve the overall care for patients with psoriasis. Objectives We studied the prevalence of genital psoriasis in the Netherlands and epidemiological characteristics of this specific presentation of the disease. Furthermore, we studied the relation between flexural and genital psoriasis. Patients/Methods A self‐administered questionnaire was sent to all 5300 members of the Dutch Psoriasis Society. Sociodemographic patient characteristics and disease‐related data (such as localization of psoriatic lesions, involvement of the genitalia, age at onset of genital psoriasis and severity of genital psoriatic lesions) were collected and analysed. Results A response rate of 37% was achieved. Almost 46% of the responding patients with psoriasis, that is 16.5% of all potential responders (n = 5300), report genital involvement at some time during the course of their disease. The genitalia can become affected at any age. Many patients with current genital involvement (38%) do not have the flexural skin affected. Conclusions A large part of patients with psoriasis suffer from genital psoriasis, which was not associated with flexural involvement in at least one third of them. More attention to the genital region is required in the current standard treatment of both male and female psoriatic patients at any age.

Latanoprost-associated recurrent herpes simplex keratitis

PURPOSE/METHOD: We present a case of a patient who developed recurrent epithelial herpes simplex keratitis after starting treatment with latanoprost. Her ophthalmic history was only remarkable for a past episode of herpetic keratitis 21 years previously. RESULTS/CONCLUSIONS: Episodes of herpetic keratitis were under remission only when latanoprost was discontinued. No recurrences of herpes simplex keratitis have been observed since then. Latanoprost usage might be associated with recurrent episodes of herpes simplex keratitis in patients with previous history of ocular herpes simplex virus infection.     

Peripheral multineuritis pointing at systemic sarcoidosis

We report a patient with a peripheral neuropathy as the first symptom of sarcoidosis. The systemic illness was proved by the presence of typic granulomes in the bone marrow. The fact that sarcoidosis is the cause for the neuropathy is supported by the temporary relation and by the good response of all clinical picture to the corticosteroid therapy.Sarcoid neuropathy can rarely be the presenting feature of sarcoidosis.     

山苍子水提物柠檬醛抗哮喘作用的实验研究

目的：研究山苍子水提物柠檬醛的抗哮喘作用及其机理。方法：通过豚鼠氯化乙酰胆碱-磷酸组胺喷雾致喘法、小鼠浓氨水喷雾引咳法、小鼠酚红排泻法观察柠檬醛的平喘、镇咳、祛痰作用，通过观察张力变化研究柠檬醛对豚鼠离体气管环张力的影响及乙酰胆碱对气管收缩的抑制作用。结果：柠檬醛能明显延长氯化乙酰胆碱-磷酸组胺喷雾引起的豚鼠哮喘潜伏期，能延长浓氨水喷雾诱发小鼠咳嗽反应潜伏期，明显减少咳嗽次数。能增加小鼠呼吸道酚红排泌量，能抑制乙酰胆碱对豚鼠离体气管平滑肌的收缩作用，使乙酰胆碱所致气管平滑肌量效曲线右移。结论：柠檬醛气雾剂具有一定的平喘、镇咳和祛痰作用，具有良好的支气管解痉作用。
