Objective: To analyze CD36 gene by PacBio Sequel Ⅱ the third-generation sequencing technology (TGS), including non-coding sequence, and to investigate the molecular mechanism of CD36 deficiency. Methods: Flow cytometry was performed in the southern Chinese population to detect the CD36 phenotype. Among them, 15 cases of CD36 type I deficiency, 15 cases of CD36 type Ⅱ deficiency, and 10 positive samples were selected. The TGS of the CD36 gene was performed and statistical analysis was conducted. Results: 40 samples (including 15 cases of type I deficiency, 15 cases of type Ⅱ deficiency, and 10 positive samples) were subjected by TGS of CD36 full-length sequences (except part of intron1). A total of 180 polymorphic loci were identified. Among them, 13 kinds were in the coding region, the rest were in non-coding region, with most mutations located in regulatory regions such as the 5′-UTR and 3′-UTR. Conclusion: The high polymorphism of CD36 non-coding regions, particularly in regulatory sequences, provides mechanistic insights into type Ⅱ CD36 deficiency.

Objective:
To explore the correlation among picky eating levels in preschool children, parental self-efficacy and parenting stress.
Methods:
A convenience sampling method was employed to conduct an electronic questionnaire survey among 459 children aged 3-6 years and their parents from five kindergartens in Urumqi in November 2023. The survey included a general information questionnaire, the Children s Eating Behavior Questionnaire (CEBQ), the Parenting Sense of Competence Scale (PSOC), and the Parenting Stress Index-Short Form (PSI-SF). The Mann-Whitney U-test was used for twogroup comparisons, and the Kruskal-Wallis H-test was applied for multi-group comparisons. Spearman correlation analysis was conducted to examine the relationships between children s picky eating levels and parenting selfefficacy as well as parenting stress.
Results:
The picky eating score of preschool children was 10.00 (4.00), and the parenting self-efficacy score was 58.00 (12.00), both indicating a moderate level. The parenting stress score was 75.00 (16.00), reflecting a moderately low level. Spearman correlation analysis showed that children s picky eating levels were negatively correlated with the total score of parenting self-efficacy ( r =-0.28) and positively correlated with the total score of parenting stress( r =0.25)( P <0.01).
Conclusions
Picky eating levels of preschool children are closely associated with parenting self-efficacy and parenting stress. Picky eating behaviors in children can be reduced by implementing various effective measures to enhance parenting self-efficacy and alleviate parenting stress.

Objective: To explore the role of the c.598G>A mutation of the ITGB3 gene in the occurrence of fetal and neonatal alloimmune thrombocytopenia (FNAIT) through its expression in vitro. Methods: The platelet antibodies in the sera of the affected neonate and her mother were detected using commercial enzyme-linked immunosorbent assay (ELISA), solid-phase agglutination, flow cytometry and the gold standard monoclonal antibody-specific immobilization of platelet antigens (MAIPA). The common human platelet antigen (HPA) genotypes of the neonate and her parents were obtained using the HPA-SSP method. The presence of mutations was analyzed by sequencing the exons of the ITGB3 and ITGA2B genes. The target gene of ITGB3 was obtained by PCR amplification using the existing human platelet cDNA. The wild-type ITGB3 eukaryotic expression vector was constructed by TA cloning technology. The 598G>A mutant ITGB3 eukaryotic expression vector was obtained by point mutation, and the plasmid DNA was co-transfected with that of ITGA2B (αⅡb) into HEK293 cells. The transfected cells stably expressing GP Ⅱb/Ⅲa were screened and obtained. The expression of GP Ⅱb/Ⅲa in 598G>A mutant transfected cells and the presence of antibodies against this mutation in the serum of mother were detected by flow cytometry and MAIPA. Results: Antibodies against HLA-class Ⅰ and GP Ⅱb/Ⅲa glycoproteins were detected in the serum of the neonate's mother, and subsequent HLA antibody-specific testing confirmed the presence of antibodies against HLA-B

02∶05. ITGB3 sequencing showed that the neonate and her father carried the c.598G>A point mutation, which results in the change of glutamate to lysine at position 200. Antibodies against GP Ⅱb/Ⅲa glycoproteins were not detected using constructed c.598G>A mutant transfected cells reacted with the maternal serum. Conclusion: The in vitro expression and analysis of the ITGB3 c.598G>A mutation did not support a role for this mutation in the pathogenesis of FNAIT. The establishment of this method facilitates the discovery of new platelet low-frequency antigens, and provides a theoretical foundation for the detection of antibodies against platelet antigens associated with patients with adverse pregnancy and childbirth histories.

5.Correlation between depressive symptom and traditional Chinese medicine constitution among school aged children and adolescents
Chinese Journal of School Health 2025;46(9):1222-1225
Objective:
To explore the correlation between traditional Chinese medicine (TCM) constitution and depressive symptom among school aged children and adolescents, so as to provide evidences for informing constitution based regulation and prevention of depressive symptom.
Methods:
From June to December 2024, a total of 4 729 students aged 6-14 were recruited by cluster random sampling from 10 primary schools in Baoding (Hebei Province), Heze and Liaocheng (Shandong Province). General information, TCM constitution and depressive symptom were collected. Restricted cubic spline (RCS) models were used to analyze related factors and threshold effects of depressive symptom. Binary Logistic regression was applied to examine the association between depressive symptom and TCM constitution, with subgroup analyses conducted.
Results:
The detection rate of depressive symptom among the included children and adolescents was 25.82%. RCS analyses indicated non linear associations between depressive symptom and age (inflection point at 10 years old), bedtime (inflection point at 22:00), and wake up time (inflection point at 6:30 ) (all P non linearity <0.01). Linear associations were observed with body mass index (BMI) and sleep duration (all P non linearity > 0.05 ). After adjusting for covariates such as age, BMI and sleep status, binary Logistic regression analyses showed that Yin deficient constitution ( OR =1.26, 95% CI =1.09-1.45) and Phlegm-dampness constitution ( OR =1.42, 95% CI =1.11-1.82) were significantly associated with depressive symptom among children and adolescents (all P <0.05).
Conclusions
Depressive symptom among school aged children and adolescents is primarily associated with Yin deficiency and Phlegm dampness constitutions in TCM constitution. Active attention should be paid to susceptible TCM constitution among children and adolescents. Targeted health guidance and interventions should be implemented to improve TCM constitution health status for preventing the occurrence of depressive symptom.

Objective:To compare the effectiveness of the Cancer Fatigue Scale (CFS) and the Revised Piper Fatigue Scale (PFS-R) in screening cancer-related fatigue (CRF) in lung cancer patients with chemotherapy.Methods:This study was a cross-sectional study. From June 2022 to March 2023, convenience sampling was used to select 162 lung cancer patients who underwent chemotherapy in the Oncology Department of Jiangsu Cancer Hospital as the study subject. CFS and PFS-R were used for CRF screening, using the diagnostic criteria proposed in the Clinical Practice Guidelines for Cancer-related Fatigue in China as the gold standard. The area under the receiver operating characteristic ( AUC), sensitivity, specificity, and Youden index of the two screening tools were compared. Results:The incidence of CRF in lung cancer chemotherapy patients was 61.1% (99/162). According to the presence of CRF, the patients were divided into CRF group ( n=99) and non-CRF group ( n=63). The CFS score and PFS-R score of patients in the CRF group were higher than those in the non-CRF group, and the differences were statistically significant ( P<0.05). The AUC of CFS was 0.840 with an optimal cutoff value of 2.470, and the sensitivity, specificity, and Youden index were 0.758, 0.873, and 0.631, respectively. The AUC of PFS-R was 0.918 with an optimal cutoff value of 4.500, and the sensitivity, specificity, and Youden index were 0.899, 0.937, and 0.836, respectively. The AUC of PFS-R was higher than that of CFS, and the difference was statistically significant ( Z=2.232, P<0.05) . Conclusions:Compared with CFS, PFS-R has a better evaluation effect and is more suitable as a screening tool for CRF in lung cancer patients with chemotherapy.

Objective:To explore the effect of continuous nursing based on Siebens domain management model in patients with Parkinson's disease after deep brain stimulation.Methods:From January 2021 to June 2022, convenience sampling was used to select 169 Parkinson's disease patients who underwent deep brain electrical stimulation in the Functional Neurosurgery of Beijing Tiantan Hospital as the study subject. The patients were divided into a control group of 84 cases and an observation group of 85 cases using the random number table method. The control group received routine continuous nursing, while the observation group received the continuous nursing based on Siebens domain management model on the basis of the control group. This study compared the Activity of Daily Living (ADL) Scale, Morisky Medication Adherence Scale (MMAS), 39-item Parkinson Disease Questionnaire (PDQ-39), Parkinson's Disease Sleep Scale (PDSS) scores, and unexpected program control rate between two groups of patients after six months of discharge.Results:After six months of discharge, the ability of daily living score, quality of life score, and sleep quality score of both groups of patients improved compared to before intervention ( P<0.05), and the medication adherence of the observation group patients improved compared to before intervention ( P<0.05), and the differences were statistically significant. The ability of daily living score, medication adherence, quality of life score, and sleep quality score of the observation group patients after six months were higher than those of the control group, and the differences were statistically significant ( P<0.05). Within six months after discharge, the unexpected program control rate of the observation group was statistically lower than that of the control group ( P<0.05) . Conclusions:In the treatment and discharge rehabilitation process of Parkinson's patients treated with deep brain electrical stimulation, adopting continuous nursing based on the Siebens domain management model can help ensure patient medication compliance, improve postoperative sleep quality and quality of life, reduce unexpected program control frequency, and have certain clinical practice value.
