Objective To analyse the mutation of K17 gene in a pedigree with steatocystoma multi-plex. Methods Blood samples were obtained from 3 affected and 3 normal individuals in a family with steatocystoma multiplex, as well as from 50 unrelated healthy individuals. Mutation scanning was carried out by PCR and direct sequencing. Results A heterozygous nucleotide transition (C→T) at position 428 in exon 1 of KI7 gene, which leads to the substitution of CGC (arginine) by TGC (histidine) at codon 94, was detected in the affected individuals, but not in normal family members or the 50 unrelated individuals. Conclusion A missense mutation (428C→T) in KI7 gene has been detected in affected individuals of this family, which seems to be a molecular basis of pathogenesis of steatocystoma multiplex.

0.05).Conclusions The SCIO system is practical to assess the therapeutic effects of itraconazole and terbinafine for patients with onychomycosis.Treatment of onychomycosis with the two drugs is equally effective and safe.

Objective:To explore the degree of fear of pain in bum patients and analyze the related factors of fear of pain.Methods:519 cases of bum inpatients were selected and investigated by using the Fear of Pain Ques-tionnaire(FPQ),the Medical Coping Modes Questionnaire(MCMQ)and the Family APGAR Index(APGAR).Re-sults:The score of fear of pain in burn patients was(95.5±16.3).The results of multiple linear regression analysis showed that the score of fear of pain was positively correlated with male,moderate and severe burn and hospitaliza-tion time over 4 weeks(β=0.22,0.35,0.41),and negatively correlated with the scores of family function of the Family APGAR Index and coping style of the Medical Coping Modes Questionnaire(β=-0.29,-0.16).Con-clusion:Male patients with moderate and severe bums who have been hospitalized for more than 4 weeks are more likely to have a higher level of fear of pain,and burn patients with better family function and coping style may have a lower degree of fear of pain.
