Objective:This study examines the application of echocardiography in the prenatal diagnosis of copy number variation (CNV) associated with fetal congenital heart disease (CHD).Methods:A retrospective analysis was conducted on 447 singleton pregnancies from Quanzhou Maternal and Child Care Hospital (Quanzhou Children's Hospital) from January 2019 to August 2022. These individuals underwent echocardiographic assessments suggestive of fetal CHD and subsequently received invasive prenatal diagnoses. Comprehensive karyotype analysis and chromosome microarray analysis (CMA) were performed for each case. The discrepancies in the chromosomal abnormality detection were analyzed between the results produced by CMA and karyotype analysis. Furthermore, differences in the detection of pathogenic copy number variation (pCNV) between the two methods in CHD cases with diverse cardiac phenotypes, including the presence or absence of extracardiac structural malformations, the type, and quantity of cardiac structural anomalies, were explored. Statistical analysis was conducted using the Chi-square test. Results:Compared with conventional karyotype analysis, CMA demonstrated a higher detection rate of fetal chromosomal abnormalities [10.5% (47/447) vs. 20.6% (92/447), χ 2=161.56, P<0.001]. In terms of distinct cardiac phenotypes, CHD cases with extracardiac structural anomalies displayed an escalated pCNV detection rate in comparison to isolated CHD cases [11.4% (45/394) vs. 32.1% (17/53), χ 2=16.68, P<0.001]. Within the cardiac structural anomaly subgroups, increased pCNV detection rates were observed in the septal defect subgroup, conotruncal malformation subgroup, and left ventricular malformation subgroup [18.4%(29/158), 25.9%(7/27), and 25.0%(7/28) vs. 7.6%(16/210); χ 2=9.15, 9.68, and 8.55, respectively, all P<0.05]. The CMA-identified pCNV correlated with CHD included 22q11.2 deletions/duplications in eight cases, 4p16.3 deletions in two cases, 11q23.3 microduplications in two cases, 1q21.1 microdeletions/microduplications in two cases, 4q28.3 microduplications in one case, and 10p15.3 microdeletions in one case. Conclusions:CMA technology exhibited an enhanced ability to detect pCNV in fetuses with CHD. Echocardiography can guide targeted CMA screening, thereby facilitating prenatal genetic assessment of CHD.

OBJECTIVE:
To explore the diagnosis, treatment and genetic characteristics of a neonate with severe pulmonary hypertension and respiratory failure.
METHODS:
Perinatal history, clinical manifestations, laboratory finding and diagnosis and treatment data of the child were collected. Whole exome sequencing was carried out for the child, and Sanger sequencing was used to verify the candidate variants.
RESULTS:
The female neonate has developed progressive respiratory failure and refractory pulmonary hypertension shortly after birth. Conventional treatment such as mechanical ventilation, vasoactive drugs, and inhaled nitric oxide were ineffective. She has developed sustained pulmonary hypertension after weaning from extracorporeal membrane oxygenation therapy, and had died after the treatment had ceased. Whole exome sequencing revealed that she has harbored a heterozygous de novo variant of c.682_683insGCGGCGGC (p.G234Rfs*148) of the FOXF1 gene, which was predicted as pathogenic based on guidelines from the American College of Medical Genetics and Genomics (ACMG), with evidence items of PVS1_Strong+PM2_Supporting+PS2. Based on her clinical manifestations and result of genetic testing, the child was diagnosed with alveolar capillary dysplasia with misalignment of the pulmonary veins (ACD/MPV).
CONCLUSION
Discovery of the c.682_683insGCGGCGGC (p.G234 Rfs*148) variant of the FOXF1 gene has expanded the mutational spectrum of the FOXF1 gene, which has facilitated implementation of specific treatment and provided a basis for clinical diagnosis and genetic counseling.

Objective To compare and analyze the short-term efficacy of different surgical methods for Siewert type Ⅰ and type Ⅱ esophagogastric junction carcinoma. Methods We selected 82 patients who accepted radical resection of esophagogastric junction carcinoma from March 2015 to March 2018 in our department, including 53 males and 29 females, aged 48-72 (61±6) years. The patients were divided into four groups according to the surgical method: a left thoracotomy group (n=14), a laparoscopic left small thoracotomy group (n=33), a thoracoscopic Ivor-Lewis group (n=17), and a thoracoscopic McKeown group (n=18). Their clinical characteristics, operative situations, postoperative complications and survival rate were analyzed. Results Among the four groups, the left thoracotomy group cost the shortest operation time, followed by laparoscopic left small thoracotomy group, thoracoscopic McKeown group and thoracoscopic Ivor-Lewis group. The thoracoscopic McKeown group/laparoscopic left small thoracotomy group had the least bleeding. The fewest lymph nodes were dissected in the left thoracotomy group and the most in the thoracoscopic McKeown group. The laparoscopic left small thoracotomy group had the lowest total complication rate and the incidence of pneumonia and arrhythmia among the four groups (P<0.05). There was no significant difference in survival rate among the four groups (P>0.05). Conclusion For Siewert type Ⅰ and type Ⅱ esophagogastric junction carcinoma, thoracoscopy combined with laparoscopic radical resection is safe and reliable. Laparoscopic left small thoracotomy has the advantages of minimal invasiveness and complete lymph node dissection, especially for the patients with poor cardiopulmonary function, which will significantly shorten operation time and reduce postoperative complications, so it is worth to be popularized.

Objective:To construct RNA interference (RNAi) lentiviral expression vector of DEK gene, and to explore its effect on the biological behavior of liver cancer cells.Methods:Double-stranded oligo DNAs were annealed and synthesized according to the interference sequence of DEK gene by RNAi technology. Small interfering RNA expression vector pLKO.1 was cloned after enzymatic digestion. The recombinant lentiviral pLKO.1-sh hDEK was constructed, and then the virus supernatant was collected, packed and infected by 293T cells. Real-time reverse transcription PCR (RT-PCR) and Western blot were used to detect DEK expression in human liver cancer cells Bel-7402, Hu-7, SmMC-7721 and HepG2, and DEK knockdown efficiency in each group of lentivirus-infected cells. Cell proliferation ability, cloning ability, apoptosis and migration ability were detected by cell counting kit-8 (CCK8), flow cytometry and scratch test, respectively. The t-test was used to compare the mean between the two groups, and one-way ANOVA was used to compare the multiple groups.Results:Enzymatic digestion and DNA sequencing results confirmed that the recombinant lentiviral vectors pLKO.1-sh hDEK1 and pLKO.1-sh hDEK3 were successfully constructed. RT-PCR and Western blot results showed that the expression of DEK in human liver cancer cells BEL-7402 and Huh7 cells was higher, and pLKO.1-sh hDEK3 was more effective in inhibiting the DEK gene expression ( P < 0.05). Therefore, pLKO.1-sh hDEK3 was selected to infect BEL-7402 and Huh7 cells for subsequent functional experiments. CCK8 cell proliferation test result showed that the cell proliferation ability of BEL-7402 and Huh7 cells infected with recombinant lentivirus was weakened when compared with blank control and negative control group ( P < 0.05). Apoptosis results showed that the apoptosis rate of knockdown group was higher than that of blank and the negative control group ( P < 0.05). Cell scratch test result showed that the wound healing rate of knockdown group was lower than that of blank control and negative control group ( P < 0.05), and the difference was statistically significant; however, there was no statistically significant difference between blank control and negative control group. Conclusion:Targeting DEK expression in silent liver cancer cells can inhibit the cell proliferation, migration ability, and induce apoptosis, which lays the foundation for further study of the role of DEK gene in liver cancer.

To explore the correlation between hyperuricemia and renal damage in patients with lupus nephritis (LN).
Methods: The data for clinical features, laboratory and renal pathological examination were collected from 177 renal biopsy-proven LN patients with or without hyperuricemia and were retrospectively analyzed to determine the correlation between serum uric acid and renal damage.
Results: LN patients with hyperuricemia group had higher rate of hypertension and higher level of blood urea nitrogen and serum creatinine while lower estimated glomerular filtration rate (eGFR) and lower positive rate of anti-U1RNP antibody (P<0.05). In the LN patients with hyperuricemia group, renal pathological scores, including acitive index, chronic index and tubulointerstitial lesions, were higher than those in the LN patients without hyperuricemia group (P<0.05). The level of serum uric acid was positively correlated with serum creatinine, renal pathological classification and renal pathological scores while negatively correlated with eGFR (P<0.05).
Conclusion: LN patients with hyperuricemia are associated with more serious renal damage. Hyperuricemia is an important predictor for poor prognosis in patients with LN.
