OBJECTIVETo investigate the role of single nucleotide polymorphisms of the gene of diacylglycerol kinase κ (DGKK) in hypospadias in Chinese children.
METHODSWe performed direct sequencing on 2 hypospadias-related candidate single nucleotide polymorphisms of the DGKK gene (rs1934179 and rs7063116, never previously reported in the Chinese population) from 300 children with sporadic hypospadias and 200 healthy controls, and compared the results between the two groups.
RESULTSThe mutation frequencies of rs1934179 and rs7063116 were 5.0% (15/300) and 5.67% (17/300) respectively in the hypospadias patients, significantly higher than 1.5% (3/200) and 2.0% (4/200) in the normal controls (P <0.05). The mutation frequencies of rs1934179 and rs7063116 in the cases of distal and middle hypospadias were also remarkably higher (6.5%, [13/200] and 7.5% [15/200], P <0.05), but those in the proximal cases (both 2.0% [2/100]) showed no statistically significant difference from the control (P >0.05).
CONCLUSIONThe polymorphisms of the DGKK gene may be associated with hypospadias, particularly distal and middle hypospadias, in Chinese children.

Objective To explore humor experience and its relationship with theory of mind in patients with schizophrenia. Methods sixty?one schizophrenic patients without treatment and sixty?three healthy subjects were assessed with the Humor Picture Test ( HPT) ,Humor Video Test ( HVT) and the Theory?of?Mind Picture?Se?quencing Task ( ToM?PST) . Results Compared with healthy subject in HPT,schizophrenic patients showed sig?nificantly higher non?humor picture rating score (24.41 ± 8.82 vs 28.41 ± 11.56, P<0.05),and less humor picture rating score (45.65 ± 11.49 vs 34.41 ± 13.06, P<0.05). Compared with healthy subject in HVT,schizophrenic patients also showed significantly less humor video rating score (3.56 ± 0.57 vs 2.46 ± 0.79, P<0.01) and the number of standard humorous moments (3.68 ± 1.19 vs 2.42 ± 1.40, P<0.01) and the sensitivity of standard hu?morous moments?d’(humor) score (1.11 ± 0.46 vs 0.47 ± 0.42, P<0.01). Schizophrenic patients had significant?ly less total score (39.89 ± 12.33 vs 58.76 ± 0.64, P<0.01) of ToM?PST compared to normal control. Correlation analysis showed a negative correlation between d’ ( humor) score and the Positive and Negative Syndrome Scale ( PANSS) total score ( r=-0.380, P<0.01) for the patients. There was significantly negative correlation between non?humor picture rating score and ToM?PST total score ( r=-0.316, P<0.05) ,and positive correlation between d’ (humor) score and ToM?PST total score ( r=0.400, P<0.01) in schizophrenic patient. After controlling for the PANSS total score,the correlation between d’(humor) score and ToM?PST total score remained significant. Conclusion Schizophrenic patients have poor humor experience,which is related to the impairments of theory of mind.Humor experience deficit may share a common neuropsychological base with the impairment of theory of mind.
