双音节普通话言语测听词表的等价性评估

目的：本项研究针对已编制完成的具有语音平衡特性的双音节普通话测听词汇表（MSTM）进行难度等价性分析，以期挑选出具有难度一致性的一组词表应用于临床。方法：对10张（每张50词）的双音节词表进行数字化录音。选取65名年龄18～25岁具有大专以上文化程度，日常生活中以普通话为交流方式的听力正常人作为受试者。对5名受试者进行预试验，获得正式测试时所需的给声强度。对60名受试者进行正式的言语识别测试，使用SPSS11．0软件对结果进行等价性分析。结果：10张双音节测试词表中，除测试表5外，其余各表间均具有难度等价性。结论：9张双音节普通话测听词汇表具有较好的难度等价性，可应用于临床测试和实验研究中。

大学生手淫的危害、原因与预防

当代大学生手淫行为比较普遍,很多大学生在上大学之前就养成了难以自控的手淫习惯。大学生手淫既影响了他们的身心健康,对他们在校园里健康成长成材也构成了严重的威胁。从思想与心里教育角度引导大学生正确对待手淫,促使他们养成积极健康的生活习惯,对他们将来人生的健康发展及营造和谐的校园风气具有重要的作用。文章论述了当代大学生手淫的根源、手淫危害、诱发因素、手淫动机及预防、矫治措施。     

Die Durchblutung handgenähter und geklammerter Colonanastomosen

Zusammenfassung In einer tierexperimentellen Studie wurde die Durchblutung nach Anlage einer handgenähten und geklammerten End-zu-End-Anastomose am Schweinedickdarm verglichen. Bei keinem der 15 Tiere trat ein Nahtleck auf. Im Bereich handgeknoteter Fäden konnten einzelne umschriebene minderdurchblutete Gebiete festgestellt werden, die am 7. und 14. postoperativen Tag deutlich sichtbar wurden, wenn die Anastomosen vermehrt vascularisiert waren. Bei den Klammernähten wurden solche Ausfälle der Gewebsdurchblutung nicht gesehen. Die intramuralen Arterien zogen unbehindert durch die B-förmig gestalteten Klammern hindurch. Ein unauffälliges Gefäßmuster und eine abgeschlossene Anastomosenheilung wurden bei den Klammernähten nach 3 Wochen und bei Handnähten nach 4 Wochen beobachtet.

Blood supply of stapled and sutured colonic anastomoses

Summary The blood supply of end-to-end staple and suture lines in the pig colon was compared. In 15 operated animals there was no anastomotic leak. Sporadic circumscribed areas of restricted circulation could be noticed in hand-sewn anastomoses. This effect was marked on the 7th and 14th postoperative day, when vascularisation of the anastomoses was increased. Such lack of vascular supply was not seen in stapled anastomoses. The intramural arteries passed through the B-shaped staples without hindrance. An unremarkable vascular pattern and a completed healing of the anastomoses were observed after 3 weeks in staple lines and after 4 weeks in suture lines.

Immunoblotting human C4 bound to human erythrocytes in vivo and in vitro.

A study of C4 bound to human erythrocytes in vitro and in vivo has been made by immunoblotting with mouse monoclonal anti-C4c and anti-C4d and human polyclonal anti-C4d (Rodgers and Chido) following SDS-PAGE. Multi-banded patterns differentiated between C4A and C4B isotypes. Treatment of EC4b with trypsin eliminated immunoblotting but not agglutination reactions. Serum inactivation (factor I) of EC4b resulted in banding patterns similar to those obtained from patients' EC4d. Treatment of EC4b membranes with NH2OH affected many of the bands, two were lost, one was markedly reduced and others had altered SDS-PAGE mobility. Interpretation of the bands has been made in terms of C4-acceptor complexes and inactivation fragments of C4. A distinct difference in the banding of C4A and C4B isotypes has been detected.     

Cholinergic balance in dementia with Lewy bodies: reversible worsening of Parkinsonism at rivastigmine dosage modulation

We describe a patient with probable dementia with Lewy bodies (DLB) whose Parkinsonism worsened after administration of rivastigmine within the therapeutic dose range. Some extrapyramidal signs (EPS) then reversed to pre-treatment level after rivastigmine dose reduction. We draw attention to the need of EPS monitoring during titration of cholinesterase inhibitors in patients with DLB. This is the first report to our knowledge of iatrogenic worsening of Parkinsonism which was successfully managed by dose reduction.

Sommario Si descrive il caso di un paziente affetto da Demenza a corpi di Lewy (Dementia with Lewy Bodies, DLB) probabile, in cui si è assistito ad un peggioramento del parkinsonismo dopo somministrazione di rivastigmina a dosi terapeutiche. Alcuni segni extrapiramidali sono regrediti al livello pre-trattamento con una riduzione posologica di rivastigmina. Si sottolinea la necessità di un monitoraggio dei segni extrapiramidali durante la titolazione della terapia con inibitori dell’acetilcolinesterasi cerebrale in pazienti con DLB. Questo è il primo caso descritto, a nostra conoscenza, di un peggioramento iatrogeno di parkinsonismo efficacemente gestito con una riduzione posologica della terapia con rivastigmina.
