第三脑室脑膜瘤(九例报告及文献回顾)

目的探讨第三脑室脑膜瘤的组织发生学、临床特点和外科治疗。方法报道9例经影像学、手术和病理学证实的第三脑室脑膜瘤，并回顾相关文献。结果第三脑室前部脑膜瘤5例，第三脑室后部脑膜瘤4例，平均发病年龄25．6岁，无明显性别差异；最常见的症状是梗阻性脑积水，缺乏硬脑膜附着为其影像学特征。肿瘤全切除6例。结论第三脑室脑膜瘤是一种罕见的脑室内脑膜瘤，起源于中间帆脉络组织或脉络丛，经半球间裂-胼胝体-穹隆间入路是合理的手术路径选择。     

Focus cleaning using mini-thoracotomy for cavitary pulmonary tuberculosis or pulmonary tuberculoma: case study of 18 human subjects

Zusammenfassung GRUNDLAGEN: Das Ziel dieser Untersuchung war, die Machbarkeit und Wirksamkeit der Fokus-Sanierung via Mini-Thorakotomie zur Therapie einer kavernösen Lungentuberkulose zu prüfen. METHODIK: Der Mini-Thorakotomie-Zugang wurde in 18 Patienten angewendet (Alter, 25–75 Jahre; median, 47,5 Jahre). Die Patienten hatten eine kavernöse Lungentuberkulose oder ein Lungentuberkulom nach tuberkulostatischer Therapie oder waren Patienten, die auf diese Therapie nicht angesprochen haben. 8 Patienten mit chronischer kavernöser Lungentuberkulose und 10 Patienten mit Tuberkulom haben sich der Fokus-Sanierung, Spülung und Faltnaht unterzogen. ERGEBNISSE: Es gab keine operative Mortalität. Alle Patienten waren klinisch saniert, hatten keinen Nachweis für Bakterien im Sputum, im Röntgen hatten die Lungenschatten abgenommen. Die Dauer der Operation betrug 30–120 min (median, 75 min), der intraoperative Blutverlust war 100–200 ml (median, 153 ml). Der postoperative Spitalsaufenthalt betrug 21–42 Tage (median, 30 Tage). Das Follow-up nach 1–4 Jahren (median, 2,5 Jahre) zeigte keine Komplikation und kein Rezidiv der Grunderkrankung. SCHLUSSFOLGERUNGEN: MTFC ist eine sichere und technisch machbare Methode zur Therapie der Lungentuberkulose oder des Tuberkuloms bei Schonung der Lungenfunktion.     

Acetylcholine Synthesis in a Primary Culture of Porcine Intermediate Lobe Cells

Previous pharmacological studies with the pituitary gland have suggested that acetylcholine (ACh) might be involved in the regulation of intermediate lobe (IL) function. Whether ACh is endogenous to the IL cells or provided from an extrinsic source is unclear. The present experiments tested the possibility that the endocrine cells of the IL may be a source of ACh by measuring certain cholinergic markers in a primary culture of dissociated porcine cells. The endogenous ACh content was readily measurable in both the freshly dissociated IL cells and in 2- or 4-day primary cultures. Choline acetyltransferase activity was also measurable in the freshly dissociated and cultured IL cells and was reduced by 53% in the presence of a specific inhibitor, napthylvinylpyridine (50 μM). IL cells incubated in the presence of [¹⁴C]choline (1 μM) were able to synthesize [¹⁴C]ACh and the accumulation of the new ACh was inhibited by hemicholinium-3 (30 μM), a competitive inhibitor of high affinity choline uptake at cholinergic nerve terminals. In conclusion, these results demonstrate that the endocrine cells of the IL are capable of synthesizing and storing ACh.     

Neonatal osteofibrous dysplasia: a case report

We describe a case of neonatal osteofibrous dysplasia that was diagnosed 3 days after birth. Osteofibrous dysplasia is a fibro-osseous lesion rarely seen in long bones. It is also known as congenital osteitis fibrosa or ossifying fibroma of bones. Although it occurs in children under 10 years of age, it is extremely rare in newborn babies. It must be differentiated from adamantinoma due to their radiological appearance, predilection for tibia and fibula, clinical picture, and certain histological similarities.     

某农场148个家庭HBV感染的家庭聚集性分析

A family clustering analysis of HBsAg, anti-HBs, anti-HBc positive and total infected persons in 148 families on a farm was carried out by the methods of G statistic, binomial distribution and negative binomial distribution. The results consistently showed that there was significant clustering of HBsAg carriers in families, whereas there were not clustering was seen an overall HBV infected persons in families. The clustering of HBsAg carriers in families is due probably to the effect of some genetic factors. The results of G statistic analysis indicate that anti-HBc also have significant clustering in families.
