Objective To investigate the expression and prognostic significance of inhibitor of growth 4 (ING4) and tail-type homeobox transcription factor 2 (CDX2) in colorectal cancer. Methods The expressions of ING4 and CDX2 pro-teins were detected by immunohistochemistry in 99 tissue samples of colorectal cancer and 30 corresponding para-cancer-ous normal tissue samples. The data of clinic outcomes were collected. The correlations between the expressions of ING 4 and CDX2 and clinicopathological parameters were also analyzed. Results The positive expression rates of ING4 and CDX2 were 68.8%and 72.7%in colorectal cancer tissues, which were significantly lower than those of corresponding normal tissue samples (93.3% and 96.7%, P<0.05). There were significant differences in the differentiation, depth of invasion, lymph node metastasis and tumor stage between expressions of ING4 and CDX2 (P<0.05). The 5-year survival rate was significant-ly lower in ING4 negative group (35.5%) compared with that of ING4 positive group (77.9%). The 5-year survival rate was significantly lower in CDX2 negative group (48.1%) than that of CDX2 positive group (70.8%, P<0.05). The expression of ING4 was positively correlated with the expression of CDX2 in colorectal cancer. Conclusion The expressions of ING4 and CDX2 are strongly associated with the carcinogenesis, development and prognosis of the colorectal cancer,which suggests that ING4 and CDX2 might be used as prognostic markers for the colorectal cancer.

Objective To explore the characteristics of response to joint attention(RJA)under diverse guiding behaviors for pre-schoolers with moderate to severe autism spectrum disorder(ASD). Methods From March to May,2023,21 children with moderate to severe ASD and 16 children with developmental de-lays matched the physiological ages were selected from Jiaxing Sunlight Rehabilitation Kindergarten,and 16 typ-ical developmental children matched the physiological ages were selected from the kindergartens nearby.They accepted a behavioral experiment on RJA.The number of RJA,frequence of RJA and the coefficient of variation of guiding behaviors needed to RJA were compared among the three groups. Results About half of the ASD group responded after guiding of head-turning,and the others required higher levels of guiding.The frequence of RJA after guiding of head-turning was less in the ASD group than in the typical devel-opment group(χ2>6.170,P<0.05),and the coefficient of variation of guiding behaviors was more(d=4.039,P<0.001). Conclusion Preschoolers with moderate to severe ASD are able to respond to joint attention,and this ability is poorer than typically developing children.The guiding behavior of the evaluator should be considered in assessing and intervening RJA in preschoolers with ASD.

Objective:To analyse the clinical presentation and pathogenic gene mutations of a family diagnosed with primary familial brain calcification (PFBC).Methods:A pedigree with primary familial brain calcification was recruited. The clinical data of the proband who was admitted to the Affiliated Hospital of Guizhou Medical University in March 2020 and the family members were collected. The DNA sequence of myogenesis regulating glycosidase (MYORG) gene was detected by Sanger sequencing in the proband and some available family members.Results:The proband is a male, 30 years old. There was only one patient of PFBC in this family. The first symptom of the proband was vagueness of speech, and gradually extrapyramidal symptoms such as slow and flexible movement and advanced cognitive impairment appeared. The brain CT of the proband and his second brother showed extensive symmetrical calcifications, mainly located in the bilateral cerebellar hemispheres, basal ganglia and thalamus. A homozygous mutation in the exon 2 of the MYORG gene [c.1967T>C(p.I656T)] was identified in the proband and an asymptomatic patient. The heterozygous mutation of MYORG gene was also detected in four healthy family members.Conclusions:All patients with homozygous mutations of MYORG gene showed calcification in CT scan, and most of the lesions were located in basal ganglia, cerebellum, subcortical white matter and thalamus. Compared with the patients with autosomal dominant gene mutation, the patients with MYORG gene mutation had more extensive intracranial calcification lesions, and the pontocerebellar lesions were more common. The most common symptoms of MYORG gene mutation patients were dyskinesia, mainly tremor paralysis and unclear speech.
