BACKGROUND: The purpose of this study was to evaluate the safety and efficacy of subsequent radiotherapy (RT) following first-line treatment with durvalumab plus chemotherapy in patients with extensive-stage small cell lung cancer (ES-SCLC). METHODS: A total of 122 patients with ES-SCLC from three hospitals during July 2019 to December 2021 were retrospectively analyzed. Inverse probability of treatment weighting (IPTW) analysis was performed to address potential confounding factors. The primary focus of our evaluation was to assess the impact of RT on progression-free survival (PFS) and overall survival (OS). RESULTS: After IPTW analysis, 49 patients received durvalumab plus platinum-etoposide (EP) chemotherapy followed by RT (Durva + EP + RT) and 72 patients received immunochemotherapy (Durva + EP). The median OS was 17.2 months vs . 12.3 months (hazard ratio [HR]: 0.38, 95% confidence interval [CI]: 0.17-0.85, P = 0.020), and the median PFS was 8.9 months vs . 5.9 months (HR: 0.56, 95% CI: 0.32-0.97, P = 0.030) in Durva + EP + RT and Durva + EP groups, respectively. Thoracic radiation therapy (TRT) resulted in longer OS (17.2 months vs . 14.7 months) and PFS (9.1 months vs . 7.2 months) compared to RT directed to other metastatic sites. Among patients with oligo-metastasis, RT also showed significant benefits, with a median OS of 17.4 months vs . 13.7 months and median PFS of 9.8 months vs . 5.9 months compared to no RT. Continuous durvalumab treatment beyond progression (TBP) prolonged OS compared to patients without TBP, in both the Durva + EP + RT (NA vs . 15.8 months, HR: 0.48, 95% CI: 0.14-1.63, P = 0.238) and Durva + EP groups (12.3 months vs . 4.3 months, HR: 0.29, 95% CI: 0.10-0.81, P = 0.018). Grade 3 or 4 adverse events occurred in 13 (26.5%) and 13 (18.1%) patients, respectively, in the two groups; pneumonitis was mostly low-grade. CONCLUSION Addition of RT after first-line immunochemotherapy significantly improved survival outcomes with manageable toxicity in ES-SCLC.

Objective To analyze the level of occupational health literacy (OHL) and mental health status in key populations in Jiangsu Province, and explore the impact of OHL on occupational stress, depressive symptoms, anxiety symptoms and insomnia symptoms. Methods A total of 11 181 workers from Jiangsu Province from April to December 2023 were selected as the research subjects using a combination of stratified cluster random sampling and probability proportional sampling method. The OHL levels of the workers, as well as their occupational stress, depression symptoms, anxiety symptoms and insomnia symptoms, were investigated using the Occupational Health Literacy Questionnaire of National Key Populations (including Occupational Health Literacy Scale, Core Occupational Stress Scale, Patient Health Questionaire-9, Generalized Anxiety Disorder 7-item Scale, and Self-Sleep Management Questionnaire). Results The OHL level of the research subjects was 41.7%, and the literacy levels of the four dimensions of occupational health legal knowledge, basic knowledge of occupational health protection, basic skills of occupational health protection, and healthy working style and behavior were 40.6%, 76.4%, 28.0% and 54.4%, respectively. The detection rates of occupational stress, depression symptoms, anxiety symptoms and insomnia symptoms were 21.8%, 17.7%, 26.4% and 29.6%, respectively. The result of multivariable logistic analysis showed that participants with adequate OHL had a lower risk of occupational stress, depressive symptoms, anxiety symptoms, and insomnia symptoms than those without adequate OHL (all P<0.01) after controlling individual and occupational confounding factors. The odds ratios and their 95% confidence intervals were 0.448(0.402-0.499), 0.664(0.593-0.742), 0.705(0.639-0.777) and 0.885(0.809-0.969), respectively. Conclusion OHL is an independent influencing factor for occupational stress, depressive symptoms, anxiety symptoms and insomnia symptoms in key populations from Jiangsu Province. Effective measures should be taken to improve the OHL level of workers, to reduce the risks of occupational stress, depressive symptoms, anxiety symptoms and insomnia symptoms.

Objective To study the effect of ladder language training on vocabulary comprehension of children with Down syndrome(DS).Methods Fifteen DS children aged 10～18 years(average 13.89±2.42 years)were in-cluded as the experimental group and 15 DS children aged 10～18 years(average 13.56±1.81 years)were recruited as the control group.The intelligence level of the two groups was evaluated by China Binet-Simon intelligence test.The vocabulary comprehension ability of two groups of children was evaluated by Peabody picture vocabulary test re-vised(PPVT-R).The physiological age,intelligence level and vocabulary comprehension ability before intervention were matched between the two groups.The children in the experimental group had 16 ladder language training twice a week,45 minutes each time by group intervention for 16 times.The children in the control group did not receive this kind of intervention.Through comparison,the effect of ladder language training on DS children's vocabulary comprehension ability was analyzed.Results There was no significant difference in PPVT-R scores between the ex-perimental group(39.6±11.04)and the control group(39.93±10.61)before training(P＞0.05).After training,the PPVT-R score of DS children in experimental group(48.53±11.23)was significantly higher than that in con-trol group(40.2±10.63)(t(28)=2.086,P＜0.05)and was extremely significantly higher than that before training(39.6±11.04)(t(14)=-8.956,P＜0.001).There was no significant difference in PPVT-R scores between DS children in the control group before and after training(t(14)=-1.468,P＞0.05).The scores of children's under-standing abilities of nouns,verbs and adjectives in DS group after training were all higher than 80％,which was sig-nificantly higher than that before training(P＜0.001).Conclusion Ladder language training can significantly im-prove the vocabulary comprehension ability of DS children.

Objective:To analyze the changes of fasting plasma glucose(FPG)level before and after menopause.Methods:Kailuan health checkup cohort was used to extract data of women aged≥18 years who participated in the first physical examination of Kailuan physical examination cohort and had menopausal age at the end of the seventh physical examination. A total of 3 749 women with 22 057 physical examination records were included in the analysis. Natural logarithmic transformation was applied to FPG, and a segmented linear mixed-effects model was used to analyze the changes in ln-transformed FPG before and after menopause. Additionally, an interaction analysis was performed to assess the multiplicative effect of baseline age and baseline body mass index(BMI)on ln-transformed FPG concerning pre- and post-menopausal periods.Results:The average age of the first physical examination for women in this study was (45.63±4.52)years, the median menopausal age was 51(50~53)years, and the median number of physical examinations was 6(5~7)times. The results of the piecewise linear mixed effect model showed that lnFPG increased from 1 year before menopause, with an average annual increase of 0.021 mmol/L, and continued to increase from menopause to 5 years after menopause, with an average annual increase of 0.007 mmol/L. LnFPG tended to be stable after 5 years of menopause. Baseline age could affect the changes of lnFPG before and after menopause, and there was a negative multiplicative interaction between baseline age ≥45 years and the time period from 6 years to 1 year before menopause( P=0.032). Women with baseline age ≥45 years had a higher average annual increase in lnFPG from 1 year before menopause to 5 years after menopause than women with baseline age <45 years( P<0.05). On lnFPG, there was a positive multiplicative interaction between baseline BMI and time segments around menopause. Compared to women with BMI <24.0 kg/m 2, obese women displayed more annual increase in lnFPG from 6 years to 1 year before menopause as well as from menopause to 5 years after menopause( P<0.05). Conclusions:Menopause has an adverse impact on FPG, with the most significant changes occurring within the period of one year before menopause and up to five years after menopause. Age and BMI significantly influence the changes in FPG before and after menopause.

Small for gestational age (SGA) infants are more likely to experience neurocognitive impairments compared to appropriate for gestational age (AGA) infants. This paper reviews recent research on the neurocognitive development of SGA children. SGA can lead to a "brain-sparing effect" due to growth restriction, which may affect cerebral blood flow and brain structure. However, this does not guarantee normal brain development. Restrictive blood flow can result in changes in brain structure, such as reduced total white matter and gray matter volume in various brain regions, including the cerebral cortex, hippocampus and cerebellum, ultimately leading to decreased head circumference. SGA children also exhibit lower scores in all neurocognitive domains, including intelligence, attention, memory, and executive function. This may result in poor academic performance and an increased risk of social, behavioral, and neurological problems, such as cerebral palsy, epilepsy, visual and hearing impairments, as well as comorbidities like attention deficit hyperactivity disorder(ADHD), autism spectrum disorder(ASD), anxiety, depression, and schizophrenia. Several risk factors for SGA-related neurocognitive impairments have been identified, including gestational hypertension, abnormal gestational weight, smoking, and catch-up growth. Studies have shown that the best interventions to improve cognitive dysplasia include nutrient supplementation, continued breastfeeding, high-quality education, and appropriate early intervention (responsive parenting) are effective in improving cognitive outcomes for SGA children.

This paper discusses the mechanism of acupuncture for diabetes mellitus from the perspective of molecular biology, aiming to reveal the potential rules of restoring the balance in the body and fighting against diabetes mellitus (DM). By searching the basic research literature of acupuncture treatment for DM, it is found that the molecular biological mechanism of acupuncture treatment for DM is closely related to the regulation of insulin signaling pathway, the modulation of inflammatory response, the protection and regeneration of islet β-cells, fat metabolism and energy balance. It points out that there are few studies of acupuncture on the type 1 diabetes mellitus and the large-scale randomized controlled trials, as well as the studies on the upstream regulation mechanism, the specific cellular molecules and the interaction mechanism of various molecules. It needs to deepen the multi-level, multi-target and multi-dimensional exploration on the molecular biological mechanism of acupuncture for diabetes mellitus.

OBJECTIVE: To explore the genetic basis of two fetuses with an osteogenesis imperfecta (OI) phenotype. METHODS: Two fetuses diagnosed at the Affiliated Hospital of Weifang Medical College respectively on June 11, 2021 and October 16, 2021 were selected as the study subjects. Clinical data of the fetuses were collected. Amniotic fluid samples of the fetuses and peripheral blood samples of their pedigree members were collected for the extraction of genomic DNA. Whole exome sequencing (WES) and Sanger sequencing were carried out to identify the candidate variants. Minigene splicing reporter analysis was used to validate the variant which may affect the pre-mRNA splicing. RESULTS: For fetus 1, ultrasonography at 17+6 weeks of gestation had revealed shortening of bilateral humerus and femurs by more than two weeks, in addition with multiple fractures and angular deformities of long bones. WES revealed that fetus 1 had harbored a heterozygous c.3949_3950insGGCATGT (p.N1317Rfs*114) variant in exon 49 of the COL1A1 gene (NM_000088.4). Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), it was classified as a pathogenic variant (PVS1+PS2+PM2_Supporting) for disrupting the downstream open reading frame resulting in premature translational termination, being de novo in origin, and lacking records in the population and disease databases.For fetus 2, ultrasonography at 23 weeks of gestation also revealed shortening of bilateral humerus and femurs by one and four weeks, respectively, in addition with bending of bilateral femurs, tibias and fibulas. Fetus 2 had harbored a heterozygous c.1557+3A>G variant in intron 26 of the COL1A2 gene (NM_000089.4). Minigene experiment showed that it has induced skipping of exon 26 from the COL1A2 mRNA transcript, resulting in an in-frame deletion (c.1504_1557del) of the COL1A2 mRNA transcript. The variant was inherited from its father and had been previously reported in a family with OI type 4. It was therefore classified as a pathogenic variant (PS3+PM1+PM2_Supporting+PP3+PP5). CONCLUSION The c.3949_3950insGGCATGT (p.N1317Rfs*114) variant in the COL1A1 gene and c.1557+3A>G variant in the COL1A2 gene probably underlay the disease in the two fetuses. Above findings not only have enriched the mutational spectrum of OI, but also shed light on the correlation between its genotype and phenotype and provided a basis for genetic counseling and prenatal diagnosis for the affected pedigrees.
