Two new asexual genera and six new asexual species in the family Microthyriaceae (Dothideomycetes, Ascomycota) from China.

The family Microthyriaceae is represented by relatively few mycelial cultures and DNA sequences; as a result, the taxonomy and classification of this group of organisms remain poorly understood. During the investigation of the diversity of aquatic hyphomycetes from southern China, several isolates were collected. These isolates were cultured and sequenced and a BLAST search of its LSU sequences against data in GenBank revealed that the closest related taxa are in the genus .

sp. nov. (, Chaetosphaeriales), a new species of freshwater hyphomycetes from southwest China.

During a mycological survey of freshwater hyphomycetes on submerged leaves in southwest China, a new species, , was isolated. The new species is characterized by having monophialidic conidiogenous cells with funnel shaped collarettes and globose or subglobose, aseptate and hyaline conidia. Morphologically, is somewhat similar to and in conidiophores and conidiogenous cells, but can be easily distinguished by its subglobose to globose and smaller conidia.

sp. nov. from Yunnan, China and two new members of .

, an aquatic hyphomycete collected from south-western PR China, is described as a new species. This new species is characterized by having multicellular branched conidia composed of a curved main axis and one or two laterals, with the laterals arising from the third or fourth cell of the base of the main axis. Combined analyses of the LSU, SSU, and gene sequence data revealed that and another aquatic hyphomycete genus, , belonged to Wiesneriomycetaceae, Tubeufiales, Dothideomycetes, Ascomycota.

[An outbreak of mycoplasma pneumoniae pneumonia in a kindergarten].

Objective: To study the epidemiological and clinical features of the mycoplasma pneumoniae pneumonia (MPP) that occurred in a single class of a kindergarten in Beijing in July 2006.

Methods: The environment and the attendance record of the kindergarten from the beginning of August 2005 to the end of July 2006 were investigated, and the sick status of the children absent for illness were interviewed by face to face or telephone through their parents. The disease data of the in-patient children with MPP were collected through questionnaires and analyzed.

[Current infection of Mycoplasma pneumoniae in adults: clinical analysis of 13 hospitalized patients].

Objective: To investigate the clinical characteristics of Mycoplasma pneumoniae (MP) current infection in adults.

Methods: The clinical data of 13 patients in Beijing, 7 males and 6 females, aged 21.9 (17 - 34), hospitalized from April 2003 to April 2004, were reviewed retrospectively.

[Preliminary screening of nocturnal sleep breathing disturbance in patients with ischemic cerebral stroke].

Objective: To investigate nocturnal sleep breathing disturbance in patients with ischemic cerebral stroke.

Methods: Forty-one patients with cerebral infarction undertook all-night screening of sleep breathing. The clinical features between cerebral infarction concomitant with mild and severe sleep breathing disturbance were compared, and the effects of different infarcted sites and sizes, the infarction history and symptoms on the breathing disorders were analyzed.
