Objective:To explore the genetic basis of two children with unexplained psychomotor developmental delay and facial dysmorphisms suggestive of Coffin-Siris syndrome (CSS).Methods:A boy and a girl suspected for CSS at the 980th Hospital of the People′s Liberation Army Joint Service Support Force respectively in July 2019 and January 2021, and seven members from their families, were selected as the study subjects. Clinical data and family history of the children were collected, and detailed physical examination was carried out, in addition with laboratory and related auxiliary examinations. Potential variants and copy number variations (CNVs) were detected by whole exome sequencing (WES) and copy number variation sequencing (CNV-seq).Results:Child 1, an 8-month-old female, had featured microcephaly, atrial septal defect, curving of fifth finger/toe, and low limb muscle tone. Child 2 was a 2.5-year-old male with language delay, social impairment, dense hair but no curving of the fifth fingers. Genetic testing revealed that child 1 had loss of heterozygosity for exons 8 to 21 of the ARID1B gene, which was unreported previously. Family verification showed that both of her parents were of the wild type. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG) and American Society of Molecular Pathology (AMP), the variant was rated as pathogenic (PVS1+ PS2+ PM2-supporting). Child 2 was found to harbor a heterozygous c. 4263-6 (IVS17) T>G variant of the ARID1B gene. Transcriptome sequencing confirmed that the variant can affect the normal splicing, resulting in retention of a 5 bp sequence in intron 17. Family verification showed that both of his parents were of the wild type. Based on the guidelines from the ACMG, the variant was rated as pathogenic (PS2+ PM2-supporting+ PP3+ PS3). Conclusion:WES and RNA-seq have confirmed the diagnosis of CSS in both children. Discovery of the novel variants has expanded the spectrum of pathogenic mutations underlying CSS, and provided a basis for the genetic counseling.

Myopia shows a trend of high incidence and low age,and the number of high myopia patients is increasing year by year.Safe and effective myopia intervention measures are the top priority of myopia prevention and control.It has been found that low-dose atropine,orthokeratology,repeated low-level red light and other treatment methods have reliable efficacy,which can provide a variety of options for myopia prevention and control in children.The choroid,as an impor-tant anatomical structure of the fundus,is closely related to the mechanism of myopia.Choroidal parameters may become markers for evaluating the effect of myopia prevention and control and monitoring the progression of myopia.With the con-tinuous development of medical imaging technology,choroidal thickness and microcirculatory parameters have been accu-rately quantified.Further exploration of the changes of choroid under various myopia intervention measures will help clini-cians design personalized treatment plans for different patients,which is of great clinical significance for the management of myopia prevention and control.In this article,the research progress on choroidal thickness and blood flow changes under different myopia prevention and control measures are reviewed.

Objective:To investigate the diagnostic value of serum serine protease (Corin) in chronic renal failure (CRF) complicated with heart failure.Methods:A retrospective analysis was conducted on 120 patients, (64.05±13.89) years old, 77 male (64.17%), with chronic renal failure combined with heart failure admitted to Zhengzhou People′s Hospital from January 1, 2023, to December 31, 2023. The control group consisted of 87 patients, (60.59±8.78) years old, 54 male (62.07%), with simple chronic renal failure. Clinical information, laboratory test indicators and echocardiographic parameters were collected. Serum Corin concentration was measured using enzyme-linked immunosorbent assay (ELISA). The experimental group was divided into grade Ⅱ(31 cases), grade Ⅲ(47 cases) and grade Ⅳ(42 cases) according to the New York College of Cardiology heart function classification system. Serum Corin levels were compared between the experimental group and the control group and among different cardiac function grades. Spearman correlation analysis was performed to evaluate the relationship between serum Corin and brain natriuretic peptide (BNP), D-dimer. ROC analysis was conducted to assess the predictive value of serum Corin in CRF complicated with heart failure and cardiac function classification; Binary Logistic regression was used to construct a multi-index joint prediction model, the joint prediction probability was obtained, and ROC curve was drawn to compare the diagnostic value of serum Corin and BNP in CRF combined with heart failure and the diagnostic value of serum Corin combined with D-dimer and BNP in CRF combined with heart failure.Results:The serum Corin level[2 568.97±477.70 pg/ml vs. 1 727.81±480.60 pg/ml, t=12.47, P<0.001], BNP [700.00(256.00, 2 089.75) pg/ml compared with 88.00 (43.00, 230.00) pg/ml, Z=-9.00, P<0.001], D-dimer [1 150.00(643.00, 1 874.75)μg/L compared with 556.00 (301.00, 865.00)μg/L, Z=-6.57, P<0.001] in chronic renal failure complicated with heart failure group was higher than that in simple CRF group, and the difference was statistically significant. Among patients with CRF complicated with heart failure, serum Corin[2 231.74±311.39 pg/ml vs. 2 562.09±365.30 pg/ml vs. 2 825.57±536.83 pg/ml, F=74.33, P<0.001], BNP [234.00(168.00, 612.00) pg/ml compared with 514.00(260.00, 1 455.00) pg/ml compared with 2 200.00(640.50, 4 682.75) pg/ml, H=29.42, P<0.001], D-dimer [753.00(514.00, 1 280.00) μg/L compared with 1 187.00(590.00, 1 840.00) μg/L compared with 1 603.00(810.00, 3 313.25) μg/L, H=14.98, P<0.001] increased with the increase of cardiac function grade, and the difference was statistically significant. According to Spearman correlation analysis, serum Corin was positively correlated with BNP ( r=0.409) and D-dimer ( r=0.299), P<0.001. According to the ROC analysis, the AUC of serum Corin in the diagnosis of CRF complicated with heart failure and cardiac function grade Ⅱ, Ⅲ, Ⅳ were 0.890(95% CI 0.846-0.935), 0.807 (95% CI 0.728-0.885), 0.911 (95% CI 0.864-0.959), 0.927 (95% CI 0.882-0.972) respectively; the AUC of BNP in the diagnosis of CRF complicated with heart failure was 0.867 (95% CI 0.817-0.916), the AUC of serum Corin combined with D-dimer, BNP combined with D-dimer, serum Corin combined with D-dimer and BNP in the diagnosis of CRF complicated with heart failure were respectively 0.930 (95% CI 0.897-0.962), 0.892 (95% CI 0.847-0.936), 0.952 (95% CI 0.927-0.977). Conclusions:Serum Corin expression is elevated in patients with CRF complicated with heart failure, and the degree of elevation is related to cardiac function grade. Serum Corin has a good diagnostic value for CRF complicated with heart failure and its severity. Serum Corin is expected to become a new biomarker for diagnosis of CRF complicated with heart failure.

Objectives:
. Despite the efficacy of surgical treatments, the high rate of recurrence in juvenile nasopharyngeal angiofibroma (JNA) after surgery remains an unresolved problem. The present study comprehensively analyzed the risk factors and characteristics of JNA recurrence, providing clinical guidance for reducing recurrence.
Methods:
. A total of 123 patients who underwent surgery for JNA between 1997 and 2019 at a single hospital were analyzed retrospectively. Univariate and multivariate analyses were used to assess the clinical risk factors for the recurrence of JNA. The relapse-free survival and annual cumulative recurrence rates were analyzed for subgroups defined according to clinical parameters.
Results:
. After screening, 78 of the 123 patients were included in the present study. The main risk factors associated with JNA recurrence included the year of diagnosis, tumor size, sphenoid bone invasion, Radkowski stage, surgical approach, and intraoperative bleeding. Importantly, the surgical approach and sphenoid bone invasion were independent prognostic factors affecting recurrence. Patients who underwent endoscopic surgery without sphenoid bone invasion exhibited longer relapse-free survival. In the present study, the overall cumulative recurrence rate of JNA was 38.7%, and recurrence occurred mainly in the first year after the initial surgery.
Conclusion
. Endoscopic surgery achieved better relapse-free survival in JNA patients, and patients with sphenoid bone invasion should be carefully explored to avoid residual JNA. The recurrence rate of JNA differed among subgroups defined based on clinical parameters and was highest in the first year after surgery. Computed tomography or magnetic resonance imaging, along with close follow-up, should be performed strictly within 1 year after the primary operation.

Objective:To compare the detection rate of genital Chlamydia trachomatis (CT) DNA between urine and urethral/cervical swab samples. Methods:From December 2018 to December 2019, a total of 1 475 outpatients were collected from sexually transmitted disease clinics in 7 medical institutions, such as Department of Venereology, Guangzhou Institute of Dermatology, including 1 118 males and 357 females. One urethral/cervical swab sample and one urine sample were collected successively from each patient. Real-time fluorescence-based PCR was performed to detect CT DNA in urine and urethral/cervical swab samples, and paired chi-square test was used to compare the positive rate of CT DNA between the 2 kinds of samples. Random- or fixed-effect meta-analysis was conducted for the test of heterogeneity and merging of positive rates of CT DNA in the urine and urethral/cervical swabs among 7 medical institutions.Results:The positive rate of CT DNA in the urine samples was significantly higher than that in the swab samples from 4 medical institutions (all P < 0.05) , while there was no significant difference in the positive rate of CT DNA between the 2 kinds of samples from 3 medical institutions (all P > 0.05) . The heterogeneity ( I2) estimates of the CT-DNA positive rate in urine and swab samples among different medical institutions were 78.6% (95% CI: 55.9% - 89.6%) and 73.7% (95% CI: 43.7% - 87.7%) , respectively; meta-analysis showed that the total merged positive rate of CT DNA in the urine samples was 10.8% (95% CI: 7.2% - 15.9%) , which was significantly higher than that in the swab samples (7.8%, 95% CI: 4.9% - 12.1%; χ2 = 39.2, P < 0.05) . Compared with the swab sample-based CT-DNA detection method, the sensitivity, specificity, positive predictive value, negative predictive value and consistency rate of the urine sample-based CT-DNA detection method were 97.0% (128/132) , 96.3% (1 293/1 343) , 71.9% (128/178) , 99.7% (1 293/1 297) , and 96.3% (1 421/1 475) , respectively. The positive rate of CT DNA in the urine samples from 1 118 male patients was 11.0% (95% CI: 7.2% - 16.5%) , which was significantly higher than that in the swab samples (7.6%, 95% CI: 4.9% - 11.8%; χ2 = 34.3, P < 0.05) . There was no significant difference in the positive rate of CT DNA between the urine (11.9%, 95% CI: 7.7% - 17.9%) and cervical swab samples from 357 female patients (10.4%, 95% CI: 7.6% - 14.0%; χ2 = 3.2, P > 0.05) . Conclusions:The positive rate of CT DNA in urine samples is higher than or similar to that in urethral/cervical swab samples. The urine sample-based CT-DNA detection method has characteristics of convenience, non-invasiveness, painlessness and low cost, and is worthy of clinical promotion.

OBJECTIVE:
To investigate the expression profile of miR-122-5p in melanoma tissues and the effect of miR-122-5p on the proliferation, cell cycle and apoptosis of human melanoma cell lines SK-MEL-110 and A375.
METHODS:
The expression profiles of miR-122-5p in melanoma and pigmented nevus tissues were detected using real-time fluorescence quantitative PCR (qRT-PCR). SK-MEL-110 and A375 cells transfected with miR-122-5p inhibitor or negative control inhibitor (NC) I were examined for miR-122- 5p expression using qRT-PCR and changes in cell proliferation, cell cycle and apoptosis using MTT assay or flow cytometry. NOP14 mRNA and protein expressions in the cells were detected using qRT- PCR and Western blotting, respectively. Luciferase reporter assay was used to confirm the identity of NOP14 as the direct target of miR-122-5p.
RESULTS:
The relative expression of miR-122-5p in human pigmented nevus tissues and melanoma tissues was 1.23±0.270 and 7.65 ± 1.37, respectively. The relative expression of miR-122-5p in SK-MEL-110 and A375 cells transfected with miR-122-5p inhibitor was 0.21 ± 0.08 and 0.17 ± 0.05, respectively. miR-122-5p inhibitor obviously inhibited the cell proliferation and increased the percentage of cells in G1 stage in both SK-MEL-110 and A-375 cells, but did not cause obvious changes in the apoptosis of the two cells. miR-122-5p inhibitor did not significantly affect the expression level of NOP14 mRNA, but obviously increased the expression level of NOP14 protein. Luciferase reporter assay revealed a significantly lower luciferase activity in cells co-transfected with miR-122-5p mimics and wild-type psi-CHECK2-3'UTR plasmid than in the cells cotransfected with NC and wild-type psi-CHECK2-3'UTR plasmid (0.21 ± 0.14 0.56 ± 0.1, < 0.01).
CONCLUSIONS
miR-122-5p expression is upregulated in melanoma tissues, indicating its involvement in the development of melanoma. miR-122-5p inhibits the proliferation of SK-MEL-110 and A-375 cells possibly by affecting the cycle through NOP14.

Objective To determine the expression of Caspase 8 and phospho-Akt(p-Akt)in condyloma acuminatum(CA)lesions, and to evaluate their significance. Methods Skin lesion samples were collected from 30 patients with CA, cancer tissue samples from 20 with cervical cancer, and normal skin samples from 20 healthy controls. All the samples were subjected to paraffin embedding. An immunohistochemical study was conducted to determine the expression and distribution of Caspase 8 and p-Akt in the above samples. Results The expression rate of Caspase 8 was significantly lower in CA lesions (23.33%)than in normal skin samples(90%, P < 0.01)and cervical cancer lesions(80%, P < 0.001). Moreover, the expression rate of p-Akt in CA lesions(93.33%)was significantly higher than that in the normal skin samples(90%, P<0.001), but lower than that in the cervical cancer lesions(95%, P<0.001). No significant correlations were observed between the expression of Caspase 8 and p-Akt in either CA lesions or normal skin samples. However, the expression of Caspase 8 was positively correlated with the expression of p-Akt in cervical cancer lesions(r=0.369, P<0.05). Conclusion Both suppressed apoptosis initiation of Caspase 8 and anti-apoptotic effect of p-Akt may be involved in the occurrence and development of CA.
