Objective: To explore the effects of a classroom based transdiagnostic preventive intervention program for emotional disorders on depressive and anxiety symptoms, and resilience among junior high school students, so as to provide reference for promoting adolescent mental health. Methods: From October to December 2023, 72 students from a junior high school in Beijing were recruited as research subjects and divided into an intervention group ( n =36) and a control group ( n =36). The intervention group participated in 8 sessions (40 mins per session) of transdiagnostic prevention intervention course for emotional disorders; the control group students participated in research based learning lessons or class meetings. Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), and Resilience Scale-8 (RS-8) were used to evaluate junior high school students. The Wilcoxon signed rank test was used to compare the differences in depressive and anxiety symptoms, and resilience scores between the intervention group and the control group before and after the intervention. PROCESS macro was used to test the mediating effect. Results: There were no statistically significant differences in the scores of depressive and anxiety symptoms, and resilience before and after intervention in the intervention group ( Z =-1.07, 0.07, 1.43, all P >0.05). In the control group, the depressive symptoms score was higher after the intervention than before, and the resilience score was lower than before the intervention ( Z = 2.23 , -2.53, both P <0.05). After intervention, the depressive symptoms score in the intervention group was lower than that in the control group, and the resilience score in the intervention group was higher than that in the control group ( Z =-2.09, 3.33, both P < 0.05). The increase in the scores of resilience played a complete mediating role between the intervention and depressive symptoms, with the mediating effect value being -0.98 (95% CI =-2.47 to -0.11), accounting for 30.98% of the total effect. Conclusion Transdiagnostic preventive intervention program for emotional disorders based on classroom could prevent the deterioration of depressive symptom in junior high school students, and maintaining the level of resilience is an important factor for the intervention effect.

Microbial communities such as those residing in the human gut are highly diverse and complex, and many with important implications for health and diseases. The effects and functions of these microbial communities are determined not only by their species compositions and diversities but also by the dynamic intra- and inter-cellular states at the transcriptional level. Powerful and scalable technologies capable of acquiring single-microbe-resolution RNA sequencing information in order to achieve a comprehensive understanding of complex microbial communities together with their hosts are therefore utterly needed. Here we report the development and utilization of a droplet-based smRNA-seq (single-microbe RNA sequencing) method capable of identifying large species varieties in human samples, which we name smRandom-seq2. Together with a triple-module computational pipeline designed for the bacteria and bacteriophage sequencing data by smRandom-seq2 in four human gut samples, we established a single-cell level bacterial transcriptional landscape of human gut microbiome, which included 29,742 single microbes and 329 unique species. Distinct adaptive response states among species in Prevotella and Roseburia genera and intrinsic adaptive strategy heterogeneity in Phascolarctobacterium succinatutens were uncovered. Additionally, we identified hundreds of novel host-phage transcriptional activity associations in the human gut microbiome. Our results indicated that smRandom-seq2 is a high-throughput and high-resolution smRNA-seq technique that is highly adaptable to complex microbial communities in real-world situations and promises new perspectives in the understanding of human microbiomes.

Computational approaches for predicting drug-target interactions (DTIs) are pivotal in advancing drug discovery. Current methodologies leveraging heterogeneous networks often fall short in fully integrating both local and global network information. To comprehensively consider network information, we propose DHGT-DTI, a novel deep learning-based approach for DTI prediction. Specifically, we capture the local and global structural information of the network from both neighborhood and meta-path perspectives. In the neighborhood perspective, we employ a heterogeneous graph neural network (HGNN), which extends Graph Sample and Aggregate (GraphSAGE) to handle diverse node and edge types, effectively learning local network structures. In the meta-path perspective, we introduce a Graph Transformer with residual connections to model higher-order relationships defined by meta-paths, such as "drug-disease-drug", and use an attention mechanism to fuse information across multiple meta-paths. The learned features from these dual perspectives are synergistically integrated for DTI prediction via a matrix decomposition method. Furthermore, DHGT-DTI reconstructs not only the DTI network but also auxiliary networks to bolster prediction accuracy. Comprehensive experiments on two benchmark datasets validate the superiority of DHGT-DTI over existing baseline methods. Additionally, case studies on six drugs used to treat Parkinson's disease not only validate the practical utility of DHGT-DTI but also highlight its broader potential in accelerating drug discovery for other diseases.

Obesity and metabolic dysfunction-associated steatotic liver disease (MASLD) are linked to numerous chronic conditions, including cardiovascular disease, atherosclerosis, chronic kidney disease, and type II diabetes. Previous research identified the natural flavonoid diosmin, derived from Chrysanthemum morifolium, as a regulator of glucose metabolism. However, its effects on lipid metabolism and underlying mechanisms remained unexplored. The AMP-activated protein kinase (AMPK) pathway serves a critical function in glucose and lipid metabolism. The relationship between diosmin and the AMPK pathway has not been previously documented. This investigation examined diosmin's capacity to reduce lipid content through AMPK pathway activation in hepatoblastoma cell line G2 (HepG2) and 3T3-L1 cells. The study revealed that diosmin inhibits lipogenesis, indicating its potential as an anti-obesity agent in obese mice. Moreover, diosmin demonstrated effective MASLD alleviation in vivo. These findings suggest that diosmin may represent a promising therapeutic candidate for treating obesity and MASLD.

OBJECTIVE To study the anatomic characteristics of the anterior ethmoidal canal(AEC)based on 0.1 mm ultra-high resolution CT.METHODS Nine cadavers(18 side orbits)fixed in 10%buffered formalin were enrolled and underwent U-HRCT and MSCT.Divided AEC into horizontal,superior oblique,and inferior oblique segments and observed the displaying rate of each section.Subjective evaluation of display situation was performed by two experienced radiologists independently.The diameter of each AEC segment was measured.RESULTS No significant difference was found in the display rate of the horizontal and superior oblique segments between U-HRCT and MSCT groups(P>0.05),the display rate of inferior oblique segment of U-HRCT group was significantly higher than MSCT group(P<0.05).There was no significant difference in the objective evaluation results between two evaluators and consistency was strong.Subjective scores of each segment of AEC in U-HRCT group were 10.00 points(9.75 points,10.00 points),2.00 points(2.00 points,3.00 points)and 8.00 points(6.00 points,10.00 points),in MSCT group were7.00 points(5.75 points,8.00 points),2.00 points(2.00 points,2.00 points)and 2.00 points(2.00 points,4.00 points).Subjective scores of horizontal and inferior oblique segments of AEC in U-HRCT were higher than MSCT(P<0.05).The anteroposterior diameter of the horizontal section of AEC is(0.92±0.12)mm,the axial diameter is(1.04±0.22)mm.The anteroposterior diameter of the inferior oblique segment is(0.47±0.08)mm,and the transverse diameter is(0.50±0.06)mm.The anteroposterior diameter of the superior oblique segments is(0.66±0.11)mm,and the transverse diameter is(0.72±0.20)mm.CONCLUSION U-HRCT is better to evaluate AEC than MSCT.It could be used to help to study the anatomic characteristics of AEC before surgery to avoid complications.

Objective:To compare the enrichment effects of ultrafiltration, polyethylene glycol (PEG) precipitation, aluminum salt precipitation, and anionic membrane adsorption-elution on viruses in drinking water.Methods:Using phage MS2 as the target virus, three different concentrations of drinking water samples were prepared, and the samples were enriched by ultrafiltration 1, ultrafiltration 2, PEG precipitation, aluminum salt precipitation, and anionic membrane adsorption-elution method, respectively. Real-time fluorescence quantitative reverse transcription-polymerase chain reaction (RT-qPCR) was used to quantify MS2 nucleic acid in pre and post concentrated samples and the recovery rates of MS2 in samples with high, medium and low concentrations were compared among the five methods.Results:Comparing the MS2 enrichment recovery rates of individual enrichment method in water samples of different concentrations, ultrafiltration method 1, PEG precipitation method, aluminum salt precipitation method, and membrane adsorption-elution method were not affected by the sample concentration, and the differences of the recovery rates for the three concentration water samples among the four methods were not statistically significant ( P>0.05). The MS2 enrichment recovery rates of the five enrichment methods were significantly different in all concentration samples ( P<0.05). The recovery rates of ultrafiltration method 1 were higher in all three concentration samples, followed by aluminum salt precipitation and anionic membrane adsorption-elution, PEG precipitation were higher in high concentration samples, but lower in low and medium concentration samples, and the recovery rates of ultrafiltration method 2 were the lowest in all three concentration samples. Comparing the Ct values of MS2 in the enriched samples by five methods, the Ct values of ultrafiltration method 1 were the smallest in the three concentration water samples. There was no statistically significant difference in MS2 Ct values among the five enrichment methods in the medium and high concentration water samples ( P>0.05). In low concentration simulated water samples, only the difference of MS2 Ct value between ultrafiltration method 1 and ultrafiltration method 2 was statistically significant ( Z=16.000, P=0.016). Conclusions:Considering the operation simplicity, operation time and virus recovery rate after enrichment, ultrafiltration was the most effective method for virus enrichment in drinking water.

Metanephric adenoma is a rare renal epithelial tumor with a low incidence and lack of specific clinical manifestations，resulting in a lack of uniformity in clinical understanding and treatment. Its etiology and pathogenesis are still unclear，and it may be related to the abnormal number and structure of chromosomes 2，7，and 17，as well as mutations in genes such as BRAF V600E，NF1，and NOTCH1，etc. There may be a transformed relationship between this tumor and Wilms’ tumor and papillary renal cell carcinoma. For diagnosis，it has diverse but non-specific clinical manifestations，and it is difficult to accurately differentiate it from other tumors in the imaging examination，and the confirmation of diagnosis relies on pathological and immunohistochemical staining. Treatment is mainly based on surgery to preserve the renal unit，such as partial nephrectomy，etc.，but the difficulty of preoperative diagnosis often leads to over-treatment，and there is a lack of standardized treatment protocols for metastatic posterior renal adenoma. The aim of this article is to provide a reference for the in-depth understanding of posterior renal adenomas and to optimize the clinical diagnosis and treatment strategies.

[Purpose]To analyze the trends of disease burden for lung cancer worldwide and in China from 1990 to 2021.[Methods]Data of the disease burden of lung cancer and population demographics in 1990 and 2021 stratified by sex and age groups for global,five SDI quintiles re-gions,and eight countries including China,Japan,Republic of Korea,United Kingdom,France,United States,Canada,and Australia were extracted from the Global Burden of Disease Study 2021(GBD 2021)database.The age-standardized mortality rate(ASMR)and age-standard-ized disability-adjusted life year rate(ASDR)of lung cancer attributable to 7 level-3 risk factors in China for 1990 and 2021 were also extracted.Counterfactual analysis was used to decompose changes in lung cancer deaths and DALY from 1990 to 2021 into four contributing factors:popu-lation size,population structure,age-standardized incidence or prevalence,and lung cancer case fatality or disease severity.The percentage changes in lung cancer deaths and DALY attributed to these four factors were calculated respectively.[Results]In 2021,there were 934 704 new cases and 814 364 deaths of lung cancer in China.From 1990 to 2021,the incidence,preva-lence,mortality,and DALY rates of lung cancer in China increased faster than those worldwide and in high-middle SDI regions,which was similar to Japan and Republic of Korea.In contrast,the mortality rates of lung cancer decreased in United States and United Kingdom;and the DALY rates of lung cancer decreased in United States,United Kingdom,Canada and Australia.From 1990 to 2021,the age-related lung cancer deaths and DALY in China increased by 193.91％and 146.20％,respectively.The primary contributor to the increase in lung cancer deaths was population aging(102.82％)among men and rising age-standardized incidence(119.00％)among women,while the primary contributor to the increase in DALY was rising age-standardized prevalence for both men(153.12％)and women(218.77％).In 2021,the top three risk factors contributing to lung cancer ASMR and ASDR in China were smoking,particulate matter pollution and occupational carcinogen exposure.Compared with 1990,the ASMR of lung cancer and its proportion at-tributable to particulate matter pollution and low dietary fruits were decreased,while the propor-tions in ASDR of lung cancer attributable to smoking and secondhand smoke increased.[Conclu-sion]Lung cancer is a major public health challenge in China.Compared with worldwide,high-middle SDI regions and certain developed countries,China has experienced faster growth in the incidence,prevalence,mortality and DALY of lung cancer,especially among women.To reduce disease burden,sustained efforts on lung cancer prevention and control are urgently required in China.

OBJECTIVE: To investigate the clinical characteristics and genetic etiology of eight members from a pedigree affected with epidermolysis bullosa (EB). METHODS: A girl presented with recurrent, unexplained blisters on the palmar and plantar skin for 8 years and sought medical care in October 2024 was enrolled as the study subject. A retrospective study was conducted to collect the child's clinical data, and a detailed medical history was taken for her family members. Peripheral venous blood samples were collected from the child and her parents for genomic DNA extraction. Whole-exome sequencing (WES) was performed. Candidate variant was validated by Sanger sequencing. The pathogenicity of the candidate variants was classified in accordance with the Standards and Guidelines for the Interpretation of Sequence Variants issued by the American College of Medical Genetics and Genomics (ACMG, hereinafter referred to as the "ACMG Guidelines"). This study was approved by the Medical Ethics Committee of the 980th Hospital of the Joint Logistics Support Force of the Chinese People's Liberation Army (Ethics No.: 2019-KY-01). RESULTS: The proband was an 8-year-and-4-month-old female. Four months after birth, she had developed recurrent blisters on the palmar and plantar skin without obvious triggers, accompanied by significant pain. Symptoms were more severe in summer and slightly relieved in winter. Although symptomatic treatment could alleviate the symptoms, she was unable to participate in physical activities. A detailed family history revealed that her great-grandfather, grandfather, father, half-brother, great-aunt, great-aunt's son and two grandsons, as well as her aunt and aunt's son, had similar clinical manifestations. WES revealed that she has harbored a heterozygous c.556-16(IVS1)C>G (NM_000424.4) variant in the KRT5 gene, which was identified as a splice site mutation. Reverse transcription sequencing confirmed that this variant can disrupt normal splicing, resulting in retention of a 15 bp sequence in the first intron. Sanger sequencing demonstrated that the variant was inherited from the father, and the 6 aforementioned relatives with similar phenotypes have all carried the same variant (the great-grandfather, grandfather, and great-aunt had declined genetic testing due to advanced age). Based on the ACMG guidelines, this variant was classified as pathogenic (PS3+PM2_Supporting+PP3+PP1_strong). CONCLUSION Patients with epidermolysis bullosa simplex may exhibit clinical features including blistering on the skin or mucous membranes of friction-prone sites (e.g. hands, feet, elbows, and knees) following minor trauma or friction, as well as increased skin fragility. The c.556-16(IVS1)C>G (rs376462752) variant of the KRT5 gene probably underlay the pathogenesis of EB in this child. Above findings have enriched the mutational spectrum of the KRT5 gene.

Objective:To evaluate cerebrospinal fluid (CSF) flow dynamics and volume changes of pulsatile tinnitus (PT) patients induced by sigmoid sinus wall dehiscence (SSWD) using MRI.Methods:This was a cross-sectional study. Totally 55 SSWD-PT patients, and 35 age- and sex-matched healthy controls were prospectively enrolled at Beijing Tongren Hospital, Capital Medical University from October 2019 to September 2023. The CSF at the midbrain aqueduct level was analyzed based on phase-contrast MRI to obtain the flow dynamics information. Based on T 1-weighted turbo field echo sequence, the CSF was segmented and the volume of CSF was calculated using ITK-SNAP software. The Mann-Whitney U test was used to compare the differences of each parameter between the two groups. Binary logistic regression was used to analyze the parameters with statistically significant differences to obtain the independent influencing factors of SSWD-PT and establish the combined parameters. Receiver operating characteristic curve analysis was used to evaluate the efficacy of diagnosing SSWD-PT. Results:Compared with controls, the SSWD-PT group showed significantly decreased mean flux (MF), mean velocity, peak velocity( P<0.05), and significantly increased regurgitant fraction (RF), CSF volume ( P<0.05). No significant differences were observed in forward flow volume, backward flow volume, and stroke volume ( P>0.05). The logistic regression results showed that MF ( OR=0.497, 95% CI 0.305-0.808, P=0.005) and RF ( OR=1.809, 95% CI 1.040-3.147, P=0.036) were independent influencing factors of SSWD-PT. The area under the curve (AUC) of MF and RF for diagnosing SSWD-PT were 0.641 (95% CI 0.517-0.766) and 0.675 (95% CI 0.564-0.786), respectively. The AUC of the combination of MF and RF was 0.724 (95% CI 0.614-0.833). Conclusions:SSWD-PT patients have abnormal changes in CSF flow dynamics and volume. The MF and RF demonstrate moderate diagnostic value for diagnosing SSWD-PT.
