OBJECTIVES: This study aims to explore the association between single nucleotide polymorphisms (SNPs) loci near the haplotype region hg19 chr9:100560865-100660865 of the forkhead box E1 (FOXE1) gene and the occurrence of non-syndromic cleft lip with or without cleft palate (NSCL/P) in western Han Chinese population. METHODS: In the first stage, our study recruited 159 NSCL/P patients and performed targeted region sequencing to screen SNPs loci near the haplotype region of the FOXE1 gene associated with NSCL/P. In the second stage, we selected 21 common SNPs and re-enrolled 1 000 non-syndromic cleft lip only (NSCLO) patients, 1 000 non-syndromic cleft palate only (NSCPO) patients, and 1 000 normal controls to verify the association. PLINK software was used to perform Hardy-Weinberg equilibrium (HWE) test. Association analysis for common variants, gene burden analysis for rare mutations, and function prediction of SNPs with non-synonymous mutations were performed using Mutation Taster and other software programs. RESULTS: In the first stage, 126 variants, including 76 single nucleotide variants and 50 insertion-deletions were identified. All the included SNPs confirmed to HWE, and the results of gene burden analysis and prediction of functional harmfulness for rare variants were not statistically significant. Association analysis showed that rs13292899 of the FOXE1 gene was significantly associated with NSCL/P (P=1.85E-27) and was also correlated with NSCLO (P=6.41E-23) and non-syndromic cleft lip with cleft palate (NSCLP) (P=2.36E-15) subtypes. In the validation phase, rs79268293 (P=0.013, P=0.022), rs10983951 (P=0.009 2, P=0.007 6), rs117227387 (P=0.009 2, P=0.007 6), rs3758250 (P=0.009 2, P=0.007 6), and rs116899397 (P=0.009 2, P=0.007 6) were significantly associated with NSCLO and NSCPO; rs13292899 (P=0.008 5), rs74606599 (P=0.008 3), rs143226042 (P=0.008 3), and rs117236550 (P=0.01) were associated with the occurrence of NSCLO; and rs12343182 (P=0.008 7), rs10119760 (P=0.012), rs10113907 (P=0.012), and rs13299924 (P=0.012) were associated with the occurrence of NSCPO. CONCLUSIONS This study found a new susceptible SNP rs13292899 of the FOXE1 gene that is closely associated with NSCL/P and NSCLO subtype and 13 other SNPs associated with NSCLO or NSCPO.

Muenke syndrome is an autosomal dominant genetic disorder that is typically characterized by unilateral or bilateral coronal synostosis, macrocephaly, midface hypoplasia, and developmental delays. This article reports a case of Muenke syndrome with a soft cleft palate. A heterozygous missense mutation c.749C>G (p.P250A) was identified in the FGFR3 gene through genetic testing. The patient exhibited typical features including coronal synostosis, bilateral hearing loss, right accessory auricle, and developmental delays and underwent surgery to repair the soft cleft palate. Cases of Muenke syndrome with cleft palate in the literature are relatively rare, and common associated symptoms include coronal suture craniosynostosis and hearing impairment. This article reports a differential diagnosis with other craniosynostosis syndromes and provides a reference for clinical diagnosis and treatment.

The emergence of genome-wide association studies (GWAS) has greatly promoted the genetic research of non-syndromic cleft lip with or without cleft palate (NSCL/P). There have been more than 40 regions concerning NSCL/P identified by GWAS, whereas specific susceptible loci and their potential function remains unclear. In the post-GWAS era, precise localization of susceptible loci in candidate regions and exploration of underlying biological mechanism will contribute to further understanding of genetic etiology of NSCL/P. The present article reviewed the genetic and functional research strategies of NSCL/P in post-GWAS era.

The biological samples of oral genetic diseases and rare diseases are extremely precious. Collecting and preserving these biological samples are helpful to elucidate the mechanisms and improve the level of diagnose and treatment of oral genetic diseases and rare diseases. The standardized construction of biobanks for oral genetic diseases and rare diseases is important for achieving these goals. At present, there is very little information on the construction of these biobanks, and the standards or suggestions for the classification and coding of biological samples from oral and maxillofacial sources, and this is not conducive to the standardization and information construction of biobanks for special oral diseases. This consensus summarizes the background, necessity, principles, and key points of constructing the biobank for oral genetic diseases and rare diseases. On the base of the group standard "Classification and Coding for Human Biomaterial" (GB/T 39768-2021) issued by the National Technical Committee for Standardization of Biological Samples, we suggest 76 new coding numbers for different of biological samples from oral and maxillofacial sources. We hope the consensus may promote the standardization, and smartization on the biobank construction as well as the overall research level of oral genetic diseases and rare diseases in China.

Objective:To evaluate the feasibility and accuracy of a multi-dimensional peripheral quick contrast sensitivity function (pqCSF) measurement established based on Bayesian probability estimation algorithm.Methods:A cross-sectional study was conducted.Nineteen eyes of 12 healthy emmetropic subjects in Zhongshan Ophthalmic Center of Sun Yat-sen University from September 2017 to March 2018 were included, with an average age of (22.92±2.91) years.The average spherical power and cylindrical power were (-0.34±0.52)D and (-0.30±0.42)D, respectively, and the average uncorrected vision acuity was≥1.0.Based on the Bayesian probability algorithm, the peak contrast sensitivity γ max, the peak spatial frequency ? max, the bandwidth β and the low contrast intercept δ were used to quickly describe the contrast sensitivity function (CSF) curve of the full spatial frequency through multi-dimensional pqCSF method.The 16 peripheral visual field positions of all subjects were tested at 6°, 12°, 18° and 24° eccentricity of the superior, inferior, the temporal and nasal visual field by the pqCSF method, but the 18° eccentricity of temporal field, which was near the physiological blind spot, was excluded.The area under Log CSF (AULCSF) of different peripheral visual fields and the Log CSF of 19 spatial frequencies (distributed at equal intervals in logarithmic units) were compared.This study followed the Declaration of Helsinki, and the study protocol was approved by an Ethics Committee of Zhongshan Ophthalmic Center of Sun Yat-sen University (No.2018KYPJ017). Written informed consent was obtained from each subject prior to any examination. Results:With the increase of eccentricity in different visual fields, the AULCSF decreased gradually, and there were significant differences in AULCSF between different eccentricities (all at P<0.05). The AULCSF of the nasal and temporal visual field at 6°, 12° and 24° eccentricity was significantly larger than that of the superior and inferior visual field (all at P<0.05). As the distance from the fovea was increased, the pqCSF, the AULCSF, and the high-frequency cutoff were all decreased, and the standard deviation of AULCSF was increased gradually. Conclusions:The pqCSF method can depict a relatively complete peripheral CSF curve of a wide peripheral visual field, and reflect the function quality of the peripheral vision comprehensively and accurately.

Objective To explore the short-term influences of conventional internal medical treatment combined with escitalopram on cognitive function and cardiac function in elderly patients with chronic heart failure (CHF) complicated with depression disorder.Methods A total of 97 patients with CHF complicated with depression disorder in Chongqing Ninth People's Hospital,from October 2014 to October 2015,were selected and randomly divided into the antidepressant group and control group.Both groups were undergoing conventional internal medical treatment.Additionally,patients in the antidepressant group were administrated with escitalopram,while patients in the control group were treated with placebo.The degree of depression and anxiety and cognitive function were assessed by using 24-item Hamilton depression scale (HAMD-24),14-item Hamilton anxiety scale (HAMA-14) and Montreal cognitive assessment(MoCA) scale,and the plasma level of NT-proBNP,left ventricular end-diastolic dimension (LVEDD) and left ventricular ejection fraction (LVEF) were measured before and after 6-week treatment.Results After 6-week treatment,the HAMD-24 and HAMA-14 scores and plasma level of NT-proBNP in antidepressant group were lower than those in the control group,while the attention score and LVEF were greater than those in the control group,there were statistically significant differences(P＜0.05).After 6-week treatment,no statistically significant difference was found in other observed indicators between the two groups(P＞0.05).Conclnsion For elderly patients with chronic heart failure complicated with depression disorder,it is indicated that escitalopram could not only relieve their anxiety and depression,but also improve their cardiac function and attention.
