First record of disk-footed bat Eudiscopus denticulus (Chiroptera, Vespertilionidae) from China and resolution of phylogenetic position of the genus.

The disk-footed bat Eudiscopus denticulus(Osgood, 1932) is a rare species in Southeast Asia. During two chiropteran surveys in the summer of 1981 and 2019, eight and three small Myotis-like bats with distinct disk-like hindfeet were collected from Yunnan Province, China, respectively. External, craniodental, and phylogenetic evidence confirmed these specimens as E. denticulus, representing a new genus in China. The complete mitochondrial genome consistently showed robust support for E. denticulus as a basal lineage within Myotinae. The coding patterns and characteristics of its mitochondrial genome were similar to that of other published genomes from Myotis. The echolocation signals of the newly collected individuals were analyzed. The potential distribution range of Eudiscopus in Southeast Asia inferred using the MaxEnt model indicated its potential occurrence along the southern border region of Yunnan, China.

[Survey on dental caries status of migrant children aged 6-12 years in Minhang district of Shanghai].

PURPOSE: To investigate the prevalence of dental caries among migrant children aged 6-12 years in Minhang district of Shanghai, so as to provide some basic data for children health care. METHODS: Ten thousand and eleven school children in 8 primary schools of Minhang district of Shanghai were investigated by cluster random sampling. Visual examination combined with probe inspection was used to diagnose caries, and then rate of caries and DMFT (decayed，missing and filled teeth) were calculated. SPSS 13.0 software package was used for statistical analysis. RESULTS: The prevalence of caries among children aged 6-12 years was 67.07%, which was significantly higher than that in children from government-owned schools (61.99%)(P<0.01). The prevalence of caries was 75.82% in 6-year-old group and highest compared to other groups. CONCLUSIONS: It can't be optimistic about the caries prevalence among migrant children aged 6-12 years in Minhang district，Shanghai.More attentions should be payed in prevention and early intervention of dental caries for children above 6 years old.
