OBJECTIVE: To analyze the phenotype and genotype of a neonate with Osteo-oto-hepato-enteric syndrome (O2HE) and review the literature. METHODS: A female neonate diagnosed with O2HE syndrome on December 13, 2024 at the First Affiliated Hospital of Zhengzhou University was selected as the study subject, and her clinical characteristics were analyzed, and pathogenic variants were explored by whole exome sequencing (WES). This study was approved by the Medical Ethics Committee of the Hospital (Ethics No.: 2025-KY-1038). RESULTS: The proband, a female infant, was delivered by Cesarean section at 36⁺¹ weeks of gestation. Five days after birth, she had developed severe diarrhea, mild cholestasis, sensorineural hearing loss, and growth retardation. WES revealed that she has harbored novel compound heterozygous variants c.512delA (p.Lys171Serfs*64) and c.698C>A (p.Thr233Asn) of the UNC45A gene, which were inherited from her mother and father, respectively. A total of 8 English papers were retrieved, which involved 16 patients from 14 families. Combined with our case, the 17 patients included 13 (76.5%) females and 4 (23.5%) males. Four patients (23.5%) had consanguineous parents. One case was excluded from further genetic analysis due to co-morbidity with other genetic variants. The primary clinical features included diarrhea (87.5%), cholestasis (81.3%), sensorineural hearing loss (31.3%), bone fragility (37.5%), and developmental delay (50.0%). Bi-allelic compound heterozygous mutations were identified in 12 patients (75.0%), and homozygous variants in 4 (25.0%). These included missense, nonsense, frameshift and deletional variants. The c.710T>C (p.Leu237Pro) variant was identified for 5 times, 3 of which were in homozygote forms. CONCLUSION O2HE syndrome should be suspected in cases with diarrhea, cholestasis, and hearing abnormalities during early postnatal period. Genetic testing facilitate early identification, genetic diagnosis and treatment.

Objective:To analyze the phenotype and genotype of a neonate with Hypoparathyroidism-sensorineural deafness-renal dysplasia syndrome (HDR).Methods:A female neonate with HDR syndrome and thyroid deficiency detected at the First Affiliated Hospital of Zhengzhou University in on December 6, 2023 was selected as the study subject, Low-coverage whole-genome sequencing (Lc WGS) and whole exome sequencing (WES) were carried out. Using " hypoparathyroidism" " sensorineural deafness" " renal dysplasia" " HDR" " Barakat" and" GATA3" as keywords, the CNKI, Wanfang Data Knowledge Service Platform and PubMed database were searched, and the retrieval time was set from the establishment to March 2025. Results:A proband, a full-term female infant, had presented with feeding difficulty, micrognathia, and low-set ears. Serological test revealed hypocalcemia, hyperphosphatemia, hypoparathyroidism, low T3, low T4 and high TSH. Hearing test revealed bilateral sensorineural deafness. Ultrasonic test revealed absence of right kidney and thyroid. WES revealed that the she has harbored a deletion of approximately 6.67 Mb at 10p15.1p13, and Lc WGS confirmed the presence of a 6.70 Mb deletion in the same region, which was verified as a de novo variant. Literature review suggested that HDR was rarely diagnosed among neonates. Among the nine cases diagnosed in neonatal period, 66.6% (6/9) exhibited the typical triad, 77.7% (7/9) had hypoparathyroidism with hypocalcemic convulsion as the initial symptom, 22.2% (2/9) had sensorineural hearing loss or renal malformation, and 66.6% (6/9) had multiple malformations including facial dysmorphism and congenital heart disease. 55.5% (5/9) had a large deletion in the 10p15 region, whilst 33.3% (3/9) had a single gene variant. The range of the deletion had correlated with the diversity of clinical phenotypes in HDR syndrome, but the classic triad of symptoms may presented in any combination, independent of deletion size. Association of HDR with thyroid deficiency has been unreported previously.Conclusion:For neonates presenting with one of the symptoms of HDR triad or in combination with other malformations, genetic testing should be carried out.

Objective:To explore the impact of age on the genetic variant spectrum and prognosis of patients with previously untreated Diffuse large B-cell lymphoma (DLBCL).Methods:A retrospective analysis was conducted on the clinical data and follow-up information of 254 previously untreated DLBCL patients from 14 hospitals in the Jiangsu Cooperative Lymphoma Group (JCLG) enrolled from July 2018 and July 2023. Following extraction of DNA from tumor tissue samples, next-generation sequencing (NGS) technique was employed to analyze the genetic variant spectrum of the DLBCL patients, with an evaluation of the relationship between age and genetic variants as well as prognosis. This study was approved by the Medical Ethics Committee of the Affiliated Hospital of Nantong University (Ethics No.: 2023-K048-01).Results:The median age of the 254 DLBCL patients was 62 years old, with 55% of patients aged 60 years or above. Clinical evaluation showed that younger (< 60 years) patients had higher complete response (CR) (70% vs. 59%), and objective response rate (ORR) (88% vs. 79%) than older patients, though the difference between the two groups was not statistically. Survival analysis indicated that both the five-year overall survival (OS) (82.7% vs. 71.7%, P=0.006) and progression-free survival (PFS) (70.6% vs. 50.2%, P<0.05) rates were significantly higher in younger patients. NGS showed that 99.6% of the patients harbored genetic variants, with PIM1, KMT2D, TP53, MYD88, and CD79B being the most common genes. Age significantly affected the variant frequency of certain genes, with MYC variants serving an adverse prognostic factor for OS in younger patients ( P=0.001), while TP53 ( P=0.024) and BCL2 ( P=0.002) variants significantly impacted OS in older patients. Prognostic analysis identified age ≥ 60 years ( HR=3.439, 95% CI=1.318~9.874), presence of B symptoms ( HR = 2.871, 95% CI=1.133~7.307), and elevated lactate dehydrogenase ( HR=3.528, 95% CI=1.231~10.66) as independent adverse prognostic factors. Conclusion:Age, genetic variants, and clinical factors may significantly affect the prognosis of the DLBCL patients. Younger patients have better survival compared to older patients. Variants of the MYC, BCL2, and TP53 genes are closely associated with poor prognosis.

OBJECTIVE To explore the association of postoperative urinary tract infections with peripheral blood in-tercellular adhesion molecule-1(ICAM-1)gene polymorphisms in the patients with menopausal stress urinary in-continence.METHODS A total of 132 patients with menopausal stress urinary incontinence who received mid-ure-thral suspension surgery in the Third People's Hospital Affiliated to Fujian University of Traditional Chinese Med-icine from Sep.2020 to Sep.2023 were recruited as the research subjects and were divided into the infection group with 25 cases and the non-infection group with 107 cases according to the status of postoperative urinary tract in-fections.The distribution of pathogens isolated from the infection group was statistically analyzed.The peripheral blood ICAM-1 gene polymorphisms and the levels of soluble triggering receptor expressed on myeloid cells(sTREM-1),high-mobility group box 1(HMGB1)and monocyte chemoattractant protein-1(MCP-1)were ob-served and compared between the two groups.The values of the three markers in diagnosis of the postoperative u-rinary tract infections in the patients with menopausal stress urinary incontinence were analyzed.RESULTS Totally 34 strains of pathogens were isolated from the 25 patients of the infection group,21(61.76％)of which were gram-negative bacteria,Escherichia coli(11 strains,32.35％)was the predominant species of the gram-negative bacteria.The frequencies of KK genotype at K469E locus of ICAM-1 gene and K allele of the infection group were higher than those of the non-infection group,while the frequencies of EE genotype and E allele of the infection group were lower than those of the non-infection group(P＜0.05).There were significant differences in the levels of serum sTREM-1,HMGB1 and MCP-1 between the infection group and the non-infection group(P＜0.05);the MCP-1 level of the infection group was(63.68±20.63)pg/ml,higher than that of the non-infection group(t=6.472,P＜0.001).The area under the curve(AUC)value of the single detection of the three markers was lower in diagnosis of the postoperative urinary tract infections in the patients with menopausal stress urinary in-continence than that of the joint detection of the three markers(P＜0.05).CONCLUSIONS The gram-negative bacteria are dominant among the pathogens isolated from the menopausal stress urinary incontinence patients with postoperative urinary tract infections.The patients show the increased expressions of sTREM-1,HMGB1 and MCP-1;the joint detection of the three markers has more advantages in auxiliary diagnosis of the postoperative u-rinary tract infections.The susceptibility to the postoperative urinary tract infections is associated with the ICAM-1 gene polymorphisms.
