Objective: To explore the effects of personality and sleep quality with psychological distress of junior and senior high school stduents, so as to provide a reference basis for precise interventions of junior and senior high school students mental health. Methods: In October 2023, a convenience sampling method was used to select 9 034 students aged 12-17 from Shiyan City as the study subjects. The Pittsburgh Sleep Quality Index (PSQI) and Kessler Psychological Distress Scale (K10) were used to collect information on sleep quality and psychological distress of junior and senior high school stduents. Between group comparison was conducted by using t-test and Chi-square test. Generalized linear models were employed to analyze the interaction and joint effects of personality and sleep quality on psychological distress. Results: The generalized linear model analysis showed that the interaction between personality and sleep quality on psychological distress was statistically significant of junior and senior high school students(effect size=0.80, P <0.01). The general linear model analysis indicated that, after adjusting for variables such as age, gender, screen time, and daily sitting time with the extroverted and good sleep quality group as the reference, the introverted and poor sleep quality group had the largest mean difference in psychological distress scores (difference=0.51, P <0.05). When stratified by sleep quality, psychological distress scores were higher in the introverted and neutral personality groups with both poor and good sleep quality compared to the extroverted group (poor sleep quality: introverted difference=3.71, neutral difference=1.14; good sleep quality: introverted difference=2.23, neutral difference=0.57, all P < 0.05). When stratified by personality, psychological distress scores were higher in the poor sleep quality groups for introverted, neutral, and extroverted individuals compared to their good sleep quality counterparts (differences=8.66, 7.83, 7.34, all P < 0.05 ). Conclusions Personality and sleep quality have interactive and joint effects on psychological distress of junior and senior high school stduents. Personalized psychological interventions should be developed based on personality and sleep quality.

Pristimerin, which is one of the compounds present in Celastraceae and Hippocrateaceae, has antitumor effects. However, its mechanism of action in esophageal squamous cell carcinoma (ESCC) remains unclear. This study aims to investigate the efficacy and mechanism of pristimerin on ESCC in vitro and in vivo. The inhibitory effect of pristimerin on cell growth was assessed using trypan blue exclusion and colony formation assays. Cell apoptosis was evaluated by flow cytometry. Gene and protein expressions were analyzed through quantitative reverse transcription-polymerase chain reaction (qRT-PCR), Western blotting, and immunohistochemistry. RNA sequencing (RNA-Seq) was employed to identify significantly differentially expressed genes (DEGs). Cell transfection and RNA interference assays were utilized to examine the role of key proteins in pristimerin?s effect. Xenograft models were established to evaluate the antitumor efficiency of pristimerin in vivo. Pristimerin inhibited cell growth and induced apoptosis in ESCC cells. Upregulation of Noxa was crucial for pristimerin-induced apoptosis. Pristimerin activated the Forkhead box O3a (FoxO3a) signaling pathway and triggered FoxO3a recruitment to the Noxa promoter, leading to Noxa transcription. Blocking FoxO3a reversed pristimerin-induced Noxa upregulation and cell apoptosis. Pristimerin treatment suppressed xenograft tumors in nude mice, but these effects were largely negated in Noxa-KO tumors. Furthermore, the chemosensitization effects of pristimerin in vitro and in vivo were mediated by Noxa. This study demonstrates that pristimerin exerts an antitumor effect on ESCC by inducing AKT/FoxO3a-mediated Noxa upregulation. These findings suggest that pristimerin may serve as a potent anticancer agent for ESCC treatment.

Objective: To analyze the serological characteristics of anti-Mur antibodies and investigate the distribution frequency of the Mur antigen among voluntary blood donors in Shiyan, thereby providing a basis for guiding clinical transfusion and establishing a Mur blood type database. Methods: ABO blood grouping of donors and patients was performed using an automated blood typing analyzer and the gel card method, respectively. Unexpected antibody screening and identification were performed using the saline, tube anti-human globulin, and polybrene methods. The specificity of anti-Mur antibodies was confirmed using Fisher's exact probability test. Plasma treated with 2-mercaptoethanol was used to distinguish IgM and IgG antibodies. IgM and IgG anti-Mur titers were determined by the saline tube method and the anti-human globulin tube method, respectively, at 4℃, room temperature, and 37℃. A total of 1 659 donor red blood cell samples were initially screened for the Mur antigen phenotype using three samples of human-derived anti-Mur plasma by the micro-tube method. Donors who tested positive for Mur antigen were further tested by the direct antiglobulin test (DAT); those with negative results were confirmed for Mur antigen by the gel card and polybrene methods. Results: Three blood samples were identified to contain mixed IgG and IgM anti-Mur antibodies. The titers of both IgM and IgG anti-Mur antibodies were highest at 4℃, intermediate at room temperature, and lowest at 37℃. The positive frequency of the Mur antigen among voluntary blood donors in Shiyan was 1.99% (33/1 659). Conclusion: anti-Mur antibodies were detected in both blood donors and patients in our region. The Mur antigen shows a certain distribution frequency among voluntary blood donors in Shiyan. Screening for the Mur blood type and establishing a corresponding database could enhance transfusion safety.

Objective:To explore the clinical phenotype and genetic characteristics of children with childhood absence epilepsy caused by KMT2E gene variants. Methods:The clinical data of 1 case of KMT2E gene variant-associated childhood absence epilepsy admitted to the Department of Pediatric Neurology of Linyi People′s Hospital in January 2023 were collected and followed up, and the child and her family were genetically examined by using whole-exome sequencing and Sanger sequencing, and the pathogenicity of mutation loci was analyzed. The Online Mendelian Inheritance in Man, Human Gene Mutation Database, PubMed database, China National Knowledge Infrastructure, and Wanfang database were consulted with the search term " KMT2E" to summarize the clinical phenotype and genetics of the children with epilepsy associated with KMT2E gene variant. Results:The child is a female, presented with typical absence seizures at the age of 3 years and 8 months, with normal development, video electroencephalogram showing widespread spikes and slow waves around 3 Hz accompanied by typical absence seizures. Seizures decreased after valproic acid was applied at full dosage, and were controlled after combination with lamotrigine. Her clinical diagnosis of childhood absence epilepsy was made. The results of whole-exome sequencing showed that the child had a de novo frameshift variant c.2404dup (p.Arg802Lysfs *8) in the KMT2E gene (NM_182931.3), which had not yet been reported domestically or internationally. The c.2404dup variant was interpreted as a pathogenic variant (PVS1+PS2_Supporting+PM2_Supporting) according to the American Society of Medical Genetics and Genomics variant classification criteria and guidelines. Her parents, older brother and younger sister did not carry the variant and had a normal clinical phenotype. A total of 22 patients with epilepsy associated with KMT2E gene variants were retrieved (including this case, a total of 23 cases), including 10 females and 13 males. All of them were autosomal dominant inheritance, with 20 minor variations, including 8 frameshift variants, 7 missense variants, 2 splicing variants, 2 nonsense variants, 1 synonymous variant, and the remaining 3 cases had large fragment deletions (including 2 cases of the whole gene). Clinical manifestations mainly included epileptic seizures (5 cases of absence seizures, 7 cases of focal seizures with or without secondary tonic-clonic seizures, 9 cases of tonic-clonic seizures, 1 case of spasm seizures, 1 case of myoclonic seizures, tonic seizures, and atonic seizures, 3 cases of epileptic status, and 5 cases of refractory epilepsy, with the onset age of epilepsy ranging from neonatal to adolescence), mental retardation (21/23 cases, 4 mild, 5 moderate, and 5 severe), peculiar facial features (11/23), and autism (3/23), etc. Conclusion:KMT2E gene variant-associated epilepsy is an autosomal dominant disorder with a wide spectrum of clinical phenotypes, and the novel variant c.2404dup in the KMT2E gene identified in the present study can lead to childhood absence epilepsy, which enriches the spectrum of mutations and clinical phenotype of the KMT2E gene.

Objective:To explore the clinical and genetic characteristics of five children with epilepsies due to variants of SCN8A gene. Methods:Clinical data of five children (four males and one female) admitted to Linyi People′s Hospital due to hereditary epilepsies between August 2015 and August 2022 were collected. Whole exome sequencing was carried out for these children, and candidate variants were verified by Sanger sequencing.Results:All of the five children were found to harbor variants of the SCN8A gene. Case 1, who had benign familial infantile epilepsy, inherited a known pathogenic c. 4840A>G variant from his father with similar symptoms. Cases 2 to 4 had presented with intermediate epilepsy. Among these, case 2 has harbored a de novo c. 3967G>A variant which was rated as pathogenic (PS1+ PS2+ PM1+ PM2_Supporting+ PP3) based on the guidelines from the American College of Medical Genetics and Genomics. Cases 3 and 4 were found to respectively harbor a de novo c. 415A>T and a c. 4697C>T variant, which were both rated as likely pathogenic (PS2+ PM1+ PM2_Supporting+ PP3). Case 5, who had early-onset infantile epileptic encephalopathy transformed into Lennox Gastaut-like syndrome, has harbored a de novo c. 5615G>A variant, which was known to be pathogenic. The children had their age of onset ranging from 2 to 14 months, and all had focal seizures and generalized tonic clonic seizures. Four children (cases 1, 2, 3 and 5) had cluster seizures, four (cases 1 to 4) had become seizure-free after single or dual treatment and showed normal growth and development, whilst case 5 was drug-resistant and showed severe developmental retardation. Conclusion:The five children had new features such as cluster seizures, occasional benign seizures in adulthood, and intermediate epilepsy which are prone to relapse after discontinuation of medication, which may be attributed to the pathogenic variants of the SCN8A gene.

Objective:To explore the clinical manifestations and pathogenic variant in a family with epilepsy, developmental delay and brain deformity.Methods:Clinical data of the child and his family members who had visited the Department of Pediatrics, Linyi People's Hospital on July 2, 2022 were collected. The child, his sister and parents were subjected to high-throughput sequencing, and the result was verified by Sanger sequencing.Results:The child was a 6-year-old boy with developmentally delay and had epileptic seizures with fever sensitivity for four years. Cranial imaging showed brain dysplasia, while the video electroencephalogram showed abnormal discharge. High-throughput sequencing showed the child has harbored a heterozygous c. 5G>T (p.Arg2Leu) variant of TUBB2A gene, which was unreported previously. His sister also carried the variant and had similar clinical manifestations, whilst his parents were of the wild-type and had normal clinical phenotypes. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was classified as pathogenic (PS2+ PM2_Supporting+ PM5+ PP1+ PP2+ PP3). Conclusion:The heterozygous c. 5G>T (p.Arg2Leu) variant of the TUBB2A gene, in the form of gonadal mosaicism, probably underlay the disorders in this family.

Objective:To explore the clinical features and genetic etiology of a child with SPONASTRIME dysplasia (SD).Methods:A 9-month-old female who had presented at the Linyi People′s Hospital in August 2022 for short stature was selected as the study subject. Clinical data of the child were collected, and whole exome sequencing (WES) was carried out. Sanger sequencing was used for validating the candidate variants.Results:The child has manifested short stature, mid-face hypoplasia, joint laxity, internal knee rotation, irregularities in the metaphysis of long bones, and flat and concave lumbar vertebrae. WES revealed that she has harbored compound heterozygous variants of the TONSL gene, namely c.3088G>T (p.Glu1030*) and c. 3053G>A (p.Arg1018His), which were inherited from her phenotypically normal parents. Neither variant was reported previously. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the c. 3088G>T variant was classified as likely pathogenic (PVS1+ PM2_Supporting), whilst the c. 3053G>A was classified as a variant of uncertain significance (PM2_Supporting+ PM3+ PP3). Conclusion:The c. 3088G>T and c. 3053G>A compound heterozygous variants of the TONSL gene probably underlay the pathogenesis in this patient. Above finding has facilitated the clinical diagnosis and genetic counseling for her family.

Blinding is an important means to control and reduce measurement bias in clinical research， and blinding assessment is the main method to measure the success of the blinding method. By summarizing the current situation of blinding assessment in randomized controlled trials （RCT） of acupuncture， it was found that the report rate of blinding assessment by acupuncture RCT was relatively low， and the studies reporting blinding assessment had several problems， such as incomplete assessment individuals， unreasonable assessment questionnaires， and unscientific analysis methods， and the setting of the assessment time point is controversial. Given the above problems， this paper discussed the key elements of blinding assessment individuals， assessment questionnaires， assessment time points， and analysis methods. It is suggested that blinding assessment should be carried out on all blinded participants and personnel in the study； the assessment questionnaire should be designed by direct inquiry， with responses designed using three or more categorical options that include an "unclear" option； the early stage of the trial should be taken as the mandatory time point for assessment， integrating the evaluation index of the James blinding index and the Bang blinding index， in order to standardize the application of blinding assessment in acupuncture RCT and improve the quality of acupuncture clinical research.

To construct a simple and two-way interactive doctor-patient communication mode, in order to provide guidance tools for doctor-patient communication, improve the effectiveness of doctor-patient communication for cancer patients, optimize medical experience, reduce doctor-patient disputes, and provide new perspectives and ideas for the study of doctor-patient communication. Literature review and qualitative research were used to construct the index framework of ESER doctor-patient communication model, and Delphi method was used to revise and improve the index content, and evaluate its reliability and validity. The results showed that after two rounds of expert letter consultation, the final ESER doctor-patient communication mode was established, including 4 primary-level indicators, 8 second-level indicators and 40 third-level indicators. The positive coefficient of experts was 100% in both rounds. The authority coefficient of experts was 0.85 in the first round and 0.91 in the second round, indicated a high degree of overall authority. Coefficient of variation (CV) were less than 0.25, and the Kendall’s W coefficient for significant χ² test, P values were less than 0.05, which was statistically significant. It can be considered that the coordination degree of experts was high; Cronbach’s α coefficients in the first and second rounds of importance evaluation were 0.952 and 0.971, respectively, which indicated that the index framework had good reliability and validity. Based on the needs of cancer patients for doctor-patient communication, build a two-way interactive ESER doctor-patient communication mode, integrate medicine and humanities, which can be used as a guiding tool for medical staff to communicate with cancer patients, so as to enable doctors and patients to achieve mutual trust, cooperation and win-win results.
