Objective To investigate the relationship between cyclin A2 (CCNA2) and the prognosis of colon cancer, and its possible mechanism from the perspective of immune infiltration. Methods We downloaded the transcriptome data of colon cancer patients from The Cancer Genome Atlas database. Clinicopathological feature analysis and survival analysis were performed based on the expression levels of CCNA2. A total of 75 specimens of colon cancer and normal tissues were collected, and the expression level of CCNA2 was analyzed using immunohistochemical methods. Multivariate analysis was conducted to explore its relationship with clinicopathological features. Gene Set Enrichment Analysis (GSEA) was used to assess the potential molecular functions of CCNA2 in colon cancer. CIBERSORT algorithm was applied to calculate the correlation between CCNA2 and immune-cell infiltration in colon cancer. Results Database and immunohistochemical analyses indicated that CCNA2 was expressed at a significantly higher level in colon cancer tissues than normal tissues (P<0.001). The overall survival, disease-specific survival, and progression-free interval were all longer in the group with high CCNA2 expression than the group with low expression (all P<0.05). In tumor tissues, the expression level of CCNA2 decreased with increased pathological and TNM stages (P<0.05). The expression level of CCNA2 in normal tissues was consistently lower than that in colon cancer tissues across all clinical stages (all P<0.001). GSEA suggested that Wnt/β-catenin, KRAS, and other signaling pathways were enriched when CCNA2 was lowly expressed. CIBERSORT analysis revealed an increase in the infiltration of immune cells such as regulatory T cells and macrophages M0 when CCNA2 expression was low. Conclusion CCNA2 is highly expressed in colon cancer and closely associated with grade of pathology and TNM stage. It may recruit regulatory T cells through the KRAS and Wnt/β-catenin pathways, thereby reducing immune-cell infiltration and promoting colon cancer progression, leading to poor prognosis.
2.Delayed diagnosis of narcolepsy and differential diagnosis and treatment of epilepsy
Chinese Journal of Applied Clinical Pediatrics 2021;36(4):315-318
Narcolepsy is a rare sleep-wake rhythm disorder in clinic practice, mainly characterized by recu-rrent unstoppable sleep during the day and often accompanied by cataplexy, sleep paralysis and hypnagogic hallucinations.Clinicians′ insufficient knowledge about narcolepsy is one of the main causes of misdiagnosis and delayed diagnosis.Moreover, narcolepsy may get easily confused by epilepsy because of complex and diverse types of epileptic seizures.Therefore, it is necessary to distinguish the two forms each other.When they are comorbidity, the diagnosis and treatment will be much more difficult.In this article, the clinical characteristics of narcolepsy and the causes of delayed diagnosis were analyzed, differential diagnosis between narcolepsy and epilepsy was investigated, and practical expe-rience in diagnosis and treatment of comorbidities were summarized, so as to raise clinicians′ awareness of narcolepsy and its comorbidity with epilepsy and improve patients′ prognosis and their quality of life.

Purpose:
Elder self-neglect is a global public health issue and should be taken seriously at large. Nurses,usually working directly with elderly patients, have a better understanding of what factors may causeelder self-neglect. In this qualitative study, we explored the influencing factors of elder self-neglect fromthe perception of nurses in the context of Chinese culture.
Methods:
Face-to-face, in-depth interviews were conducted from November 2018 to December 2018.Purposive sampling was used. Twenty one participants recruited from eight geriatric wards of a generalhospital located in Wuhan were interviewed. A content analysis of qualitative nature was performed toanalyze the data.
Results:
Our conceptual model illustrated the findings based on the three themes of the conflict betweenpersonal recognition and social judgment, the choice between current needs and individual beliefs, aswell as the compromise between insufficient abilities and limited resources.
Conclusion
Nurses together with family members and social workers can help older adults improvetheir awareness of self-neglect to bridge the gap with social judgment, learn to focus on their own needs,as well as seek as much support as possible. Nurses should also respect the autonomy and selfdeterminationof elder self-neglecters because self-neglect is related to older adults' values. Furthermore,larger studies are needed to quantitatively test and refine the model.

OBJECTIVE:
To make molecular diagnosis of an infant affected with severe developmental delay and multiple birth defects, assisting prenatal diagnosis for the second pregnancy.
METHODS:
Standard G-banded karyotyping was performed for the fetus and his parents. Single nucleotide polymorphism array (SNP array) was used to detect submicroscopic chromosomal aberration. Fluorescence in situ hybridization (FISH) was employed to determine the parental origin of the aberration.
RESULTS:
Both the proband and the fetus harbored a 5.4 Mb distal 4p deletion and a 6.9 Mb distal 6q duplication. FISH confirmed that the mother has carried a balanced translocation involving 4p and 6q.
CONCLUSION
The unbalanced chromosomal aberration in the proband and the fetus were both derived from the mother. Both patients showed a Wolf-Hirschhorn syndrom phenotype and partial phenotype of 6q trisomy. SNP array combined with FISH are essential for the detection of cryptic chromosomal aberrations which may be missed by coventional karyotyping analysis.

Objective To evaluate the safety and perinatal outcomes of thoracoamniotic shunting in the treatment of fetuses with severe primary hydrothorax. Methods 22 cases of suspected severe primary fetal hydrothorax which underwent thoraco-amniotic shunting in Shanghai First Maternity and Infant Hospital,Fetal Medicine Unit and Prenatal Diagnosis Center from January 2012 to December 2017 were analyzed retrospectively. Hydrothorax associated with structural or chromosomal abnormalities, infections and immune fetal hydrops were excluded. Results Totally ,28 shunts were placed in 22 fetuses. The median gestational age at TAS was 31.3 weeks. Preterm membrane rupture within 7 days after the procedure occurred in 9.1%(2/22) cases. Catheter displacement occurred in 18%(4/22) cases. The interval from shunting to delivery was 26.0 days. One fetus ended in induced abortion; 21(95%,21/22) babies were born alive, and their median gestational age at delivery was 34.4 weeks. 62%(13/21)newborns required ventilator supports; 4 neonatal deaths were attributed to pulmonary hypoplasia. The overall perinatal survival rate was 81%(17/21). The perinatal survival rate with hydrops and without hydrops were 10/13 and 7/8 respectively. Conclusion Thoraco-amniotic shunting is a safe procedure for intrauterine therapy and could improve the perinatal outcomes of severe primary fetal hydrothorax.

OBJECTIVETo explore the origin and mechanism of small supernumerary marker chromosomes (sSMC) in order to facilitate genetic counseling.
METHODSChromosome karyotypes of two fetuses and their immediate family members were analyzed by conventional G banding. High-throughput whole genome sequencing was used to determine the origin of sSMCs.
RESULTSFetus 1 was shown to have a karyotype of 47,XY,+mar but with normal FISH and B ultrasound findings. Its father also had a 47,XY,+mar karyotype with normal FISH results and clinical phenotype. High-throughput genome sequencing revealed that fetus 1 and its father were both 46,XY,dup(21)(q11.2;q21.1) with a 6.2 Mb duplication of the long arm of chromosome 21. The fetus was born with normal phenotype and developed well. Its grandmother also had a karyotype of 46,XX,t(15;21)(q13;p13) with normal FISH result and clinical phenotype. The karyotypes of its mother and grandfather were both normal. Analysis of fetus 2 showed a 47,XY,+mar karyotype with normal FISH results. High-throughput genome sequencing suggested a molecular karyotype of 46,XX. The fetus was born with normal phenotype and developed well. The karyotypes of its parents were both normal.
CONCLUSIONConsidering their variable origins, identification of sSMC should combine conventional G banding analyses with high-throughput whole genome sequencing for precise delineation of the chromosomes.
