Objective To systematically analyze the spatiotemporal distribution characteristics and epidemiological trends of tracheal, bronchus, and lung cancer (TBL) disease burden attributed to air pollution globally and in China and the United States from 1990 to 2021, and to assess the patterns of disease burden changes from 2022 to 2031 based on predictive models, providing a scientific basis for formulating targeted TBL prevention and control strategies. Methods Based on the Global Burden of Disease (GBD) 2021 database, we analyzed the disease burden data of TBL attributed to air pollution globally and in China and the United States from 1990 to 2021. R Studio 4.3.2 software was used to analyze the corresponding trends and the Bayesian age-period-cohort (BAPC) prediction model was used to predict the status of the disease burden of TBL attributed to air pollution in the world and in China and the United States from 2022 to 2031. Results In 2021, China had the highest number of deaths and disability-adjusted life years attributed to air pollution (211 400 patients and 4.8947 million person-years), followed by the United States (6 000 patients and 124 300 person-years). The age-standardized mortality rate (ASMR) and age-standardized disability-adjusted life years rate (ASDR) of TBL due to air pollution in the world and in China and the United States showed a decreasing trend. From 1990 to 2021, the ASMR and ASDR of TBL in China due to air pollution were much higher than those in the United States and the global average. In terms of gender, from 1990 to 2021, the disease burden of male patients with TBL attributed to air pollution was much higher than that of female patients. The BAPC prediction model showed that from 2022 to 2031, the ASMR and ASDR of TBL attributed to air pollution showed an upward trend globally, while they showed a downward trend in China and the United States. Conclusion Over the past 30 years, the air pollution-related TBL disease burden in the world and in China and the United States has continued to decline, but China's disease burden is still significantly higher than the global average. The disease burden in men far exceeds that in women, with men and the population aged ≥50 years being high-risk groups. In the future, the global disease trend may reverse and rise, while China and the United States are expected to continuously decline. However, precise prevention and control for high-risk groups remains a key challenge.

Objective To investigate the differences in pathological changes and immune responses of human airway organoids at different stages of differentiation following respiratory syncytial virus(RSV)infection.Methods Models of human fetal lung organoids(FLO)and induced airway organoids(iAO)were established to simulate immature and mature airway epithelium.Immunofluorescence staining,electron microscopy,and quantitative polymerase chain reaction(Q-PCR)were used to confirm the successful construction of the lung organoid models.Human lung organoids were infected with RSV,and samples were collected at 6 and 48 hours post-infection.The immune characteristics of immature and mature RSV-infected organoids were assessed using immunofluorescence staining,droplet digital PCR(DDPCR),and Q-PCR.Results We successfully generated FLO expressing both the progenitor markers sex determining region Y-box transcription factor 2(SOX2)and sex determining region Y-box transcription factor 9(SOX9),as well as iAO containing basal cells,ciliated cells,club cells,and goblet cells.In addition,organoid models of RSV infection were established.DDPCR results showed that,at the initial stage of RSV infection,the viral load in iAO was significantly higher than that in FLO(P<0.001).However,at 48 hours post-infection,the viral load in iAO was lower than that in FLO(P<0.05).Q-PCR results indicated that the expression of RSV infection receptor genes,including epidermal growth factor receptor(EGFR),insulin-like growth factor 1 receptor(IGF1R),and nucleolin(NCL),was significantly higher in iAO compared to that in FLO(P<0.001).RSV infection led to an increase in the expression levels of immune factors,including interleukin 6(ILL-6),interleukin 8(CXCL8),interferon α(IFN-α),granulocyte colony-stimulating factor(G-CSF),granulocyte-macrophage colony-stimulating factor(GM-CSF),and tumor necrosis factor α (TNF-α),in iAO compared to those in FLO,and the differences were statistically significant(P<0.05).Conclusion The expression of RSV infection receptor proteins increases with airway maturation,and mature airway epithelial cells exhibit a stronger immune response than immature ones do,effectively inhibiting RSV replication.

Autism spectrum disorder(ASD) is a neurodevelopmental disorder, and social impairment was one of the core symptoms of ASD, which can seriously affects the social life of patients.The pathogenesis of social impairment in ASD is unclear and it may involves many brain abnormalities.The related theories and hypotheses are numerous and there is no unified conclusion. Studies have shown that the cerebellum has extensive connections with brain networks and is involved in the regulation of social cognition, but its role in ASD has not been fully emphasized.The structural and functional abnormalities of the cerebellar-cortex (CC) loop in ASD patients can lead to language communication disorders, empathy disorders, difficulties in interpreting social cues, abnormal social reward processing and emotional regulation disorders, which are closely related to ASD social impairment. Noninvasive brain stimulation of the superficial cerebellum can improve the abnormal CC circuit in ASD patients, and the cerebellum can be considered as a target for the treatment of social disorders in ASD in the future.Based on the clinical and basic researches on social impairment in ASD in recent years, this article reviews the relevant manifestations of disorders which cerebellar and CC circuit involved, aiming to promote the development of related research in the future.

Objective::This study aimed to assess the impact of proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor treatment immediately after percutaneous coronary intervention (PCI) on the myocardial salvage index (MSI) in patients with anterior ST-segment elevation myocardial infarction (STEMI) 5-10 d after the procedure.Methods::The early PCSK9 inhibitor thERapy Following pErcutaneous Coronary inTervention (PERFECT) trial is a prospective randomized controlled trial. From January 2021 to December 2023, 32 patients with anterior STEMI from Tongren Hospital, Shanghai Jiao Tong University School of Medicine, Songjiang Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, and Shanghai Tenth People’s Hospital were enrolled in the PERFECT trial. Patients were randomly assigned in a 1∶1 ratio to the PCSK9 inhibitor group ( n = 16) or the control group ( n = 16), and their baseline data were collected. Patients in the PCSK9 inhibitor group (ie, alirocumab group) received a subcutaneous injection of PCSK9 inhibitor (alirocumab, 75 mg) immediately after PCI based on conventional treatment. In the control group, patients received only conventional treatment. The primary endpoint was the MSI measured by cardiovascular magnetic resonance 5-10 d after PCI. The secondary endpoints included the left ventricular ejection fraction measured by cardiovascular magnetic resonance 5-10 d after PCI and the time to peak of creatine kinase isoenzyme-MB and high-sensitivity cardiac troponin T. Safety endpoints included any clinical adverse events that occurred during the 6-month follow-up period. Results::Baseline data during admission showed no intergroup significance. No significant difference in MSI (55.54% ± 14.80% vs. 44.72% ± 15.42%, P = 0.056) and left ventricular ejection fraction (51.24% ± 8.91% vs. 44.99% ± 8.84%, P = 0.060) was observed. Additional, there was no significant difference in the time to peak of creatine kinase isoenzyme-MB ((12.97 ± 5.67) h vs. (14.31 ± 7.04) h, P = 0.557) and high-sensitivity cardiac troponin T ((21.03 ± 12.46) h vs. (21.44 ± 9.99) h, P = 0.920) between the 2 groups. During the 6-month follow-up period, only 1 patient in the PCSK9 inhibitor group developed cerebral hemorrhage 6 months after PCI. Conclusions::Early treatment with alirocumab did not exhibit a significant increase in MSI at 5-10 d in patients with anterior STEMI. Larger trials are necessary to evaluate the impact of early administration of PCSK9 inhibitors after myocardial infarction.

BACKGROUND:
The effect of the interval between previous Helicobacter pylori (H. pylori) eradication and rescue treatment on therapeutic outcomes remains unknown. The aim of this study was to investigate the association between eradication rates and treatment interval durations in H. pylori infections.
METHODS:
This prospective observational study was conducted from December 2021 to February 2023 at six tertiary hospitals in Shandong, China. We recruited patients who were positive for H. pylori infection and required rescue treatment. Demographic information, previous times of eradication therapy, last eradication therapy date, and history of antibiotic use data were collected. The patients were divided into four groups based on the rescue treatment interval length: Group A, ≥4 weeks and ≤3 months; Group B, >3 and ≤6 months; Group C, >6 and ≤12 months; and Group D, >12 months. The primary outcome was the eradication rate of H. pylori . Drug compliance and adverse events (AEs) were also assessed. Pearson's χ2 test or Fisher's exact test was used to compare eradication rates between groups.
RESULTS:
A total of 670 patients were enrolled in this study. The intention-to-treat (ITT) eradication rates were 88.3% (158/179) in Group A, 89.6% (120/134) in Group B, 89.1% (123/138) in Group C, and 87.7% (192/219) in Group D. The per-protocol (PP) eradication rates were 92.9% (156/168) in Group A, 94.5% (120/127) in Group B, 94.5% (121/128) in Group C, and 93.6% (190/203) in Group D. There was no statistically significant difference in the eradication rates between groups in either the ITT ( P = 0.949) or PP analysis ( P = 0.921). No significant differences were observed in the incidence of AEs ( P = 0.934) or drug compliance ( P = 0.849) between groups.
CONCLUSION:
The interval duration of rescue treatment had no significant effect on H. pylori eradication rates or the incidence of AEs.

As the incidence of autism rises annually,its unknown pathogenesis makes it challenging to treat the varied repetitive and stereotyped behaviors that characterize its core symptoms.The striatum is an important brain region for the control of locomotor behaviors,featuring a unique mosaic structure,complex neural origin,and finely regulated developmental process that is highly susceptible to genetic and environmental influences.Both clinical and basic studies have indicated that abnormal development of the striatal nuclei may contribute to the pathogenesis of these repetitive stereotyped behaviors in autism.Clinical imaging data have primarily identified gross anatomical variations in the stratum(e.g.,its general outline),but lack the resolution necessary to detect the cellular and subcellular alterations within the region.By introducing the abnormalities in the spatiotemporal development of the striatum and their links to the characteristic behaviors of autism,this review aims to advance our understanding of the role of the striatum in autism pathogenesis and to inform future animal studies and clinical research.

The prefrontal cortex (PFC) plays a pivotal role in orchestrating higher-order emotional and cognitive processes, a function that depends on the precise modulation of synaptic activity. Although pharmacological studies have demonstrated that dopamine signaling through dopamine D1 receptor (DRD1) in the PFC is essential for these functions, the cell-type-specific and molecular mechanisms underlying the neuromodulatory effects remain elusive. Using cell-type-specific knockout mice and patch-clamp recordings, we investigated the regulatory role of DRD1 on neurons and astrocytes in synaptic transmission and plasticity. Furthermore, we explored the mechanisms by which DRD1 on astrocytes regulate synaptic transmission and plasticity at the cellular level, as well as emotional and cognitive functions at the behavioral level, through two-photon imaging, microdialysis, high-performance liquid chromatography, transcriptome sequencing, and behavioral testing. We found that conditional knockout of the Drd1 in astrocytes (CKOAST) increased glutamatergic synaptic transmission and long-term potentiation (LTP) in the medial prefrontal cortex (mPFC), whereas Drd1 deletion in pyramidal neurons did not affect synaptic transmission. The elevated level of d-serine in the mPFC of CKOAST mice increased glutamatergic transmission and LTP through NMDA receptors. In addition, CKOAST mice exhibited abnormal emotional and cognitive function. Notably, these behavioral changes in CKOAST mice could be reversed through the administration of d-serine degrease to the mPFC. These results highlight the critical role of the astrocytic DRD1 in modulating mPFC synaptic transmission and plasticity, as well as higher brain functions through d-serine, and may shed light on the treatment of mental disorders.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Rice (Oryza sativa L.), as a thermophilic crop, is highly susceptible to cold stress during its growth process. Chilling injury at the plumule stage and seedling stage often affects the morphological development and leads to yield reduction of rice. The exploration and utilization of cold tolerance genes are among the most direct and effective approaches to address cold stress in rice. To identify quantitative trait loci (QTLs) associated with cold tolerance at plumule and seedling stages, in this study, we measured the seedling rates and survived seedling rates of the indica rice cultivar 'HZ', the japonica cultivar 'Nekken2', and their 120 recombinant inbred lines (RILs) under cold stress. A previously constructed high-density genetic linkage map was used for the mapping of the QTLs conferring cold tolerance at the plumule and seedling stages. A total of 4 QTLs for plumule-stage cold tolerance and 9 QTLs for seedling-stage cold tolerance were detected, with the maximum limit of detection reaching 5.20. Notably, a genetically overlapping QTL for both plumule and seedling stages was identified on chromosome 8, spanning a physical interval of 24 432 953-25 295 129 bp. Candidate genes within the detected QTL intervals were screened, and quantitative real-time polymerase chain reaction (qRT-PCR) was conducted to analyze the gene expression during the plumule and seedling stages. The results revealed that LOC_Os03g06570, LOC_Os03g07100, LOC_Os06g08280, LOC_Os08g38440, LOC_Os08g39100, and LOC_Os08g39540 exhibited significantly differential expression between the parental lines. These genes were either significantly downregulated or upregulated under cold stress. Among them, the first three gene (LOC_Os03g06570, LOC_Os03g07100, and LOC_Os06g08280) were hypothesized to be key candidates regulating the cold tolerance of rice seedlings, while the latter three genes (LOC_Os08g38440, LOC_Os08g39100, and LOC_Os08g39540) were identified as comprehensive regulators of cold tolerance during both plumule and seedling stages. These findings lay a foundation for the fine mapping and cloning of cold tolerance genes at the plumule and seedling stages, providing valuable insights for breeding cold-tolerant rice varieties.

Human epidermal growth factor receptor 2 (HER2) is a key therapeutic target for breast cancer. With the wide application of anti-HER2 and HER2 antibody-drug conjugates such as trastuzumab, pertuzumab, trastuzumab emtansine, and trastuzumab deruxtecan, the survival of patients with advanced HER2-positive breast cancers have been significantly improved. However, the subsequent drug-induced interstitial lung disease (DILD) has gradually become an important complication affecting the therapeutic effect and safety. However, the clinical understanding of interstitial lung disease (ILD) caused by this type of drugs is still insufficient, the management lacks unified standards, and the molecular mechanism has not been fully clarified. This study, through two clinical cases of severe DILD, explores the pathogenesis, treatment strategies, risk factors and follow-up monitoring requirements of ILD caused by HER2-targeted drugs, providing a scientific basis for optimizing the clinical diagnosis and treatment plan.
