Objective:To investigate, for multi-sensitized allergic rhinitis (AR) patients allergic to dust mites combined with other allergens (pollen, mold, animal dander, etc.), whether the single dust mite subcutaneous immunotherapy (SCIT) can improve the specific symptoms caused by other allergens in the patients, and to analyze the relationship between the effectiveness of symptom improvement in these patients and the type, quantity and severity of the allergens.Methods:A multicenter retrospective study was conducted to collect mul-sensitized AR patients from allergy or respiratory departments of 5 hospitals who received house dust mite allergen preparation SCIT for 12 to 36 months and met other inclusion and exclusion criteria from February to July 2024. General clinical data were collected and the perennial or seasonal symptoms before and after treatment were evaluated with visual analogue scale (VAS) to assess whether there was an perennial or allergen-specific symptom improvement (VAS score decrease ≥30%), by which the patients were divided into effective group and ineffective. R software was used to analyze the differences between groups by using Fisher′s exact test and Mann-Whitney U test. Results:A total of 62 patients were enrolled, and the treatment were effective in 39 of them, with an effective rate of 62.9%. For allergen-specific symptoms, the median age of the effective group was higher than that of the ineffective group (12 years old vs. 8 years old, P=0.039), and the effective rate in dust mite specific immunoglobin E (sIgE) grade ≤5 group was higher than that in sIgE grade >5 group (81.6% vs. 45.5%, P=0.008), and the effective rate of mold sIgE grade ≤2 group was higher than that of sIgE grade >2 group (83.3% vs. 28.6%, P=0.045), and there was no statistically significant correlation between the other allergen grades and the effective rate ( P>0.05). For perennial symptoms, the effective rate in the mold grade ≤2 group was higher than that in the sIgE grade >2 group (91.3% vs. 28.6%, P=0.010), and there was no statistically significant correlation between the other allergen grades and the effective rate ( P>0.05). There was no significant correlation between the treatment effectiveness of perennial or allergen-specific symptoms and the number of combined allergens, the grade of skin test, and the difference between the grade of combined allergens and that of dust mites ( P>0.05). Conclusion:Among the patients with multi-sensitized AR allergic to dust mites included in this study, single dust mite SCIT is effective in some of them, and for allergen-specific symptoms, the effective group was elder, and dust mite sIgE grade 6 and mold sIgE grade ≥2 was related to the low effective rate of SCIT. The present results are insufficient for selecting single or multiple AIT in any type of multi-sensitized patients.

Objective:To compare the accuracy and applicability of three adult height prediction methods based on artificial intelligence-assisted bone age assessment—the Bayley-Pinneau method(BP method), the Tanner-Whitehouse 3 method(TW3 method), and China 05 method—in girls.Methods:This bidirectional cohort study collected clinical data and 690 posteroanterior X-ray images of the left hand from 278 female children who underwent pubertal development assessments at Shenzhen Children′s Hospital between January 2014 and December 2020, with follow-up until adult height was reached. Adult height prediction was performed using BP, TW3, and China 05 methods on artificial intelligence-assisted bone age assessment.Results:The BP and TW3 methods overestimated adult height by(1.7±3.7) cm and(2.6±3.0) cm, respectively, while the China 05 method underestimated adult height by(2.3±3.5) cm. The proportion of PAH within±5 cm of FAH were 80.0% for the TW3 method, 77.0% for the BP method, and 74.2% for the China 05 method, with significant differences among them( P=0.038). Analysis of cases with prediction deviations>10 cm and subgroup comparisons revealed that the TW3 and BP methods were more likely to overestimate adult height in girls aged 6.0-<8.0 years, with delayed bone age, or in the prepubertal stage(all P<0.001). The China 05 method was more prone to underestimate adult height in those with advanced bone age( P<0.001). All three methods showed significantly greater prediction errors(absolute difference between PAH and FAH) in girls with early puberty compared to those with normal pubertal development(all P<0.05). Conclusions:The TW3 and BP methods tend to overestimate adult height in girls, while the China 05 method tends to underestimate it. Caution is warranted when predicting adult height, particularly in girls under 8 years of bone age, with delayed or advanced bone age, and those with early puberty.

Objective:To analyze a novel intronic variant in the SPTB gene and explore its effect on SPTB mRNA splicing.Methods:Clinical data of a child diagnosed with hereditary spherocytosis (HS) and admitted to the First Affiliated Hospital of Xi′an Jiaotong University in February 2022 were analyzed retrospectively. Whole genome sequencing was used to identify disease-causing variantions and the results were validated with Sanger sequencing, mRNA sequencing was used to determine the SPTB gene′s mRNA expression level, and bioinformatics tools were used for splicing site prediction and analysis.Results:The proband is a 2-month-old Han male child, clinically presenting with anemia and jaundice. In the past, jaundice appeared early and was severe during the neonatal period, with significantly elevated indirect bilirubin (203.5 μmol/L), accompanied by moderate anemia. This family consisted of four generations, eight of whom suffered from splenomegaly, jaundice, and anemia. In their peripheral blood, the percentage of microglobular erythrocytes was between 5% and 10%. Under scanning electron microscopy analysis of the proband's father's peripheral red blood cells, about 6% exhibited a mouth-shaped morphology, about 4% were spherical, and about 3% were oval. Following the splenectomy, the father′s anemia and jaundice recovered to normal level. Whole genome sequencing analysis of the proband identified a heterozygous variant in the SPTB gene (NM_ 001355436.2 (SPTB):c.6022+4_6022+18delinsTGGCTCCTCCGTGAAGGGACAGTCCTGC), which was verified to be co-segregating with the disease in this family line by Sanger sequencing. The results of the SPTB gene mRNA expression level detection showed that the expression levels of the SPTB variant gene were statistically increased in the proband and affected family members (father, grandmother, cousin, second cousin, great-grandmother, great-aunt) (all P<0.05). The SPTB gene′s intron can undergo selective splicing, as demonstrated by analysis using the bioinformatics program ESE Finder. Additionally, predictions from the SpliceAI and SpliceTool software indicated that activation of a new covert splicing donor can result in a code-shift variantion that introduces an early termination codon and nonsense-mediated degradation of the mRNA, which prevents the synthesis of proteins. Conclusion:A new variantion site c.6022+4_6022+18delinsTGGCTCCTCCGTGAAGGGACAGTCCTGC was found in SPTB gene. This variantion was the pathogenic factor of HS. By affecting the splicing process, this variantion triggers the nonsense mediated mRNA degradation pathway, resulting in inactivation of gene function.

Journal of Movement Disorders 2024;17(3):282-293
Objective:
Sialidosis type 2 has variants that are both catalytically inactive (severe), while sialidosis type 1 has at least one catalytically active (mild) variant. This study aimed to discuss the structural changes associated with these variants in a newly reported family carrying N-acetyl-α-neuraminidase-1 (NEU1) variants and explore the clinical characteristics of different combinations of variants in sialidosis type 1.
Methods:
First, whole-exome sequencing and detailed clinical examinations were performed on the family. Second, structural analyses, including assessments of energy, flexibility and polar contacts, were conducted for several NEU1 variants, and a sialidase activity assay was performed. Third, previous NEU1 variants were systematically reviewed, and the clinical characteristics of patients in the severe-mild and mild-mild groups with sialidosis type 1 were analyzed.
Results:
We report a novel family with sialidosis type 1 and the compound heterozygous variants S182G and V143E. The newly identified V143E variant was predicted to be a mild variant through structural analysis and was confirmed by a sialidase activity assay. Cherry-red spots were more prevalent in the severe-mild group, and ataxia was more common in the mild-mild group. Impaired cognition was found only in the severe-mild group. Moreover, patients with cherry-red spots and abnormal electroencephalographies and visual evoked potentials had a relatively early age of onset, whereas patients with myoclonus had a late onset.
Conclusion
Changes in flexibility and local polar contacts may be indicators of NEU1 pathogenicity. Sialidosis type 1 can be divided into two subgroups according to the variant combinations, and patients with these two subtypes have different clinical characteristics.

Objective:To explore the association between insulin resistance (IR) and genome-wide DNA methylation based on Shanghai twin study.Methods:Monozygotic twins (MZ) from Shanghai were recruited during 2012-2013, 2017-2018, and 2022-2023. Data were collected by questionnaire survey, physical examination and laboratory tests. Genome-wide DNA methylation was quantified. Generalized linear mixed effect model was applied to analyze the association between methylation level at each site and homeostatic model assessment 2-insulin resistance (HOMA2-IR). Non-paired and paired designs were used to assess the association between DNA methylation and phenotype of IR. Cluster analysis was conducted to identify the clusters of top significant sites. Generalized linear regression was performed to examine the differential methylation patterns from clusters.Results:A total of 100 MZ pairs were included in this study. Hypermethylated cg10535199-2q23.1 ( β=0.74%, P=1.51×10 -7, OR=1.06, 95% CI: 1.03-1.09) and ch.17.49619327- SPOP ( β=0.23%, P=7.54×10 -7, OR=1.17, 95% CI: 1.08-1.28) were identified with suggestive significance. After correcting for multiple testing, no sites reached genome-wide significance. There was no statistical significance in the paired analysis. Two clusters with hypomethylated ( β=-0.39%, P<0.001) and hypermethylated ( β=0.47%, P<0.001) patterns were observed for HOMA2-IR. Conclusions:IR was significantly associated with DNA methylation, and genetic factors might contribute to the association.

Objective:To explore the status of quality of sexual life, self-acceptance and self-disclosure in patients with breast cancer undergoing chemotherapy after surgery, and analyze the mediating effect of self-disclosure between self-acceptance and quality of sexual life.Methods:Using convenience sampling, 209 female patients with breast cancer undergoing postoperative chemotherapy in a Class Ⅲ Grade A hospital in Zhuhai from January to October 2022 were selected for investigation by using the General Information Questionnaire, Sexual Quality of Life Questionnaire for Breast Cancer Survivors, Self-Acceptance Questionnaire (SAQ) and Distress Disclosure Index (DDI). Pearson correlation was used to analyze the correlation between quality of sexual life, self-acceptance and self-disclosure in breast cancer patients undergoing chemotherapy after surgery. Bootstrap mediating effect method was used to analyze the mediating effect of self-disclosure between self-acceptance and quality of sexual life in breast cancer patients undergoing chemotherapy after surgery.Results:The scores of the quality of sexual life (average score of items), self-acceptance and self-disclosure of breast cancer patients undergoing chemotherapy after surgery were (2.69±0.59), (38.61±5.32) and (35.90±5.73) respectively. The quality of sexual life of patients was positively correlated with self-acceptance and self-disclosure, and self-acceptance had a mediating effect on the quality of sexual life through self-disclosure ( P<0.05) . Conclusions:The quality of sexual life of breast cancer patients undergoing chemotherapy after surgery needs to be improved. Helping patients increase their self-acceptance and self-disclosure level will help them improve their quality of sexual life.

OBJECTIVE To study the effects of Shenfu yixin granule on mitochondrial autophagy of cardiomyocytes in rats with heart failure after acute myocardial infarction. METHODS The model of heart failure after acute myocardial infarction was established by ligaturing the anterior descending branch of the left coronary artery in rats. The model rats were divided into model group,Shenfu yixin granule low-dose and high-dose groups (1.76,8.8 g/kg),Fosinopril sodium tablets group (positive control ,4 mg/kg),sham operation group was set up (only threading without ligation at the same position ),with 8 rats in each group. After 4 weeks of drug intervention ,the hemodynamic indexes of rats in each group were measured by physiological recorder. The pathological changes of myocardial tissue were observed in each group. The level of oxidative stress in cardiomyocytes , mitochondrial membrane potential ,protein expression of PTEN-induced putative kinase 1(PINK1),E3 ubiquitin ligase Parkin and ubiquitin binding protein P 62 in myocardial tissue of rats in each group were detected. RESULTS Compared with sham operation group ,the pathological injuries such as myocardial fiber morphology disorder and inflammatory cell infiltration were serious. The left ventricular end systolic pressure (LVESP),maximum rate of rise of left ventricular internal pressure (+dp/dtmax), maximun rate of decrease of left ventricular internal pressure (-dp/dtmax),total antioxidant capacity ,mitochondrial membrane potential,PINK1,Parkin and P 62 protein expression were significantly decreased in model group (P<0.01). The left ventricular end diastolic pressure (LVEDP),the level of reactive oxygen species and the activity of reduced nicotinamide adenine dinucleotide phosphate in left ventricular ischemic cardiomyocytes were significantly increased (P<0.01). Compared with model group ,the pathological injuries of myocardial tissue in intervention groups were alleviated ,and above indexes were improved in varying degrees(P<0.01 or P<0.05). CONCLUSIONS Shenfu y ixin granule can reduce the level of oxidative stress and alleviate heart failure after acute myocardial infarction ,which may be related to the activation of Parkin-dependent pathway to strengthen mitochondrial autophagy and reduce mitochondrial dysfunction.
