Objective: To evaluate the efficacy and safety of ruxolitinib combined with low-dose hormone for patients with acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods: Thirty patients with aGVHD after allo-HSCT admitted to the Department of Hematology of the General Hospital of Western Theater Command from November 2021 to November 2024 were retrospectively analyzed. All patients were treated with low-dose hormone (methylprednisolone 0.3-1 mg kg
-d
) combined with ruxolitinib 5-10 mg d
. The efficacy and adverse reactions were observed during the follow-up period to analyze the survival outcomes of the patients. Results: A total of 30 patients with aGVHD after allo-HSCT were included in this study, consisting of 15 (50%) males and 15 (50%) females with a median age of 34 year-old (ranging from 14 to 62). Classification by disease type: there were 18 cases of acute myeloid leukemia, 4 cases of acute lymphoblastic leukemia, 4 cases of aplastic anemia, and 4 cases of myelodysplastic syndrome. Classification by aGVHD severity: there were 27 cases (90%) of Ⅱ-Ⅳ degree aGVHD and 11 cases (36.7%) of Ⅲ-Ⅳ degree aGVHD. Ruxolitinib in combination with low-dose glucocorticoid treatment yield responses in 28 (93.3%) patients, of which 27 (90%) achieved complete remission (CR), while 1 (3.3%) showed partial remission (PR). One patient (3.3%) had no response (NR), and 1 patient (3.3%) exhibited progressed disease (PD). Overall survival (OS) at 1 year of transplantation was 73.9% (95%CI 49.5% to 87.7%), progression-free survival (PFS) was 93.3% (95%CI 75.9% to 98.3%), non-relapse mortality (NRM) was 20.6% (95%CI 7.9% to 47.4%), and median survival time was 27.6 months. Conclusion: Ruxolitinib combined with low-dose hormones is safe and effective in the treatment of aGVHD after allo-HSCT.

BackgroundAnxiety disorder is a common mental disorder, with its prevalence showing a continuous upward trend, significantly affecting the quality of life and social function of patients. Due to the lack of objective and reliable biomarkers in clinical practice, the early identification and treatment of anxiety disorder have been somewhat limited. Plasma proteins have the potential to serve as biomarkers for mental diseases, however, the causal relationship between them and anxiety disorder remains unclear. ObjectiveTo identify the plasma proteins that have a causal relationship with anxiety disorders, and to elucidate the associated biological pathways, in order to provide references for the search for biomarkers of anxiety disorders and the exploration of potential therapeutic targets. MethodsBased on the protein quantitative trait locus (pQTL) data of 4 907 plasma proteins covering 35 559 Icelandic individuals from the deCODE database, and the genome-wide association studies (GWAS) data of 50 486 patients with anxiety disorders and 330 460 healthy controls, the inverse-variance weighted (IVW) method was used as the main analysis method, supplemented by MR-Egger method, weighted median method, simple model method, and weighted model method for bidirectional Mendelian randomization analysis. Enrichment analysis of gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways was conducted for the related proteins. Sensitivity analysis was performed using Cochran's Q test, MR-Egger intercept test, MR-PRESSO test, and leave-one-out analysis to evaluate the robustness of the results. ResultsA total of 10 plasma proteins were identified as significantly associated with anxiety disorders. Among these, SPATA9 (OR=0.856, 95% CI: 0.784–0.934, P<0.01) and PDE5A (OR=0.911, 95% CI: 0.864–0.961, P<0.01) were identified as protective factors, while CRYGD (OR=1.209, 95% CI: 1.095–1.334, P<0.01), BTN3A3 (OR=1.045, 95% CI: 1.018–1.073, P<0.01), SERPINB13 (OR=1.102, 95% CI: 1.040–1.168, P<0.01), ERBB4 (OR=1.283, 95% CI: 1.109–1.484, P<0.01), LSAMP (OR=1.096, 95% CI: 1.037–1.158, P<0.01), ICOSLG (OR=1.283, 95% CI: 1.104–1.490, P<0.01), DNAJB11 (OR=1.172, 95% CI: 1.076–1.277, P<0.01), and TREML1 (OR=1.115, 95% CI: 1.054–1.179, P<0.01) were identified as risk factors. The sensitivity analysis showed that the results were robust, with no heterogeneity (Cochran's Q test P>0.05) or pleiotropy (MR-Egger intercept test P>0.05). Enrichment analysis indicated that these plasma proteins were enriched in biological processes such as T-cell signal transduction, lymphocyte proliferation, cell membrane structure and synaptic function, as well as the intestinal immune network that produces IgA and the ErbB signaling pathway. ConclusionThis study identified 10 plasma proteins associated with anxiety disorders. The functions of these plasma proteins involve multiple biological processes such as neural development and immune regulation.

To analyze the clinical and genetic features of oculopharyngodistal myopathy (OPDM) patients and compare the phenotypic differences among various causative genes. A total of 65 genetically confirmed OPDM patients from 43 unrelated families, who were admitted to the Department of Neurology, Peking University First Hospital between January 2008 and December 2025, were retrospectively included.The general demographic data, clinical manifestations, laboratory/auxiliary examinations, muscle pathology, and genetic test results were systematically collected and analyzed. The clinical and pathological characteristics among different OPDM subtypes were compared. Among the 65 patients(39 male and 26 female), the mean age of onset was (31.20±10.43) years (range: 14 to 63 years). The initial symptom was predominantly distal limb weakness (67.44%), which gradually progressed to involve the extraocular muscles, pharyngeal muscles, facial muscles and proximal limb muscles. Serum creatine kinase levels were mildly to moderately elevated. Muscle pathological examinations revealed rimmed vacuoles and intranuclear inclusions (within muscle fibers). The mean duration from onset to diagnosis was (12.33±7.88) years (range: 1 to 32 years). All probands had negative results on conventional next-generation whole-exome sequencing; pathogenic variants were identified through third-generation long-read sequencing or OPDM-targeted repeat-primed polymerase chain reaction(RP-PCR). Among the 43 families, OPDM2 subtype was the most common genetic subtype ( OPDM2 was the predominant subtype in this study. All subtypes share similar age of onset and muscular pathological changes, yet exhibit distinct disease progression patterns. Future multicenter prospective cohort studies are warranted to further elucidate the clinical characteristics, pathogenetic mechanisms, and prognostic differences among OPDM subtypes.

In the context of burgeoning economic trade, there has been a remarkable increase in the number of ships travelling between domestic and international ports. Inbound and outbound cargo ships, cruise liners, ferries, and other types of vessels have emerged as critical vehicles for the dispersal of vector organisms and the spread of infectious disease agents. Public health concerns associated with these vessels represent a significant threat to human welfare. In this paper, we comprehensively review the hazards posed by vector organisms on ships, the latest advances in prevention and control strategies, and proposes appropriate countermeasures. The aim is to provide effective guidance for the prevention and control of public health security issues caused by ship-borne vector organisms.

ObjectiveTo investigate the possible mechanism of Pibai Yucuo Formula (枇柏愈痤方, PYF) in treating acne from the perspective of skin barrier damage. MethodsThirty-two mice were randomly divided into blank group, model group, minocycline group, and PYF group, with 8 mice in each group. Except for the blank group, mice were induced by intradermal injection of Cutibacterium acnes (C.acnes) combined with topical application of artificial sebum to establish acne model. The blank group and model group received intragastric administration of 0.2 ml of distilled water, while the PYF group received intragastric administration of 22.75 g/(kg·d)of PYF, and the minocycline group received 0.013 g/(kg·d)of minocycline suspension, all once daily for 5 consecutive days. On day 0 and day 6 of the experiment, the body weight of mice in each group was recorded, and the absolute value of the body weight difference during the experiment was calculated. Skin conditions were assessed with multifunctional skin imaging system on the 2nd, 4th and 6th day of the experiment. Skin barrier function indicators including transepidermal water loss (TEWL), and the water content of the stratum corneum and epidermis on day 0, 2, 4 and 6 of the experiment. Optical coherence tomography (OCT) was used to observe stratum corneum and skin thickness on the 1st, 3rd and 5th day of the experiment. Hematoxylin-eosin (HE) staining was performed to observe histopathological changes, while ELISA was used to detect interleukin-17A (IL-17A) levels, and immunofluorescence staining was used to assess skin barrier-related proteins filaggrin (FLG) and loricrin (LOR) levels of skin lesions on day 6 of the experiment. ResultsCompared to the blank group, the model group showed a decrease in body weight on day 6, and an increase in the absolute value of the difference in body weight before and after the experiment (P<0.05). On day 4 and 6, TEWL values increased, while water content in the skin stratum corneum and epidermis decreased (P<0.05), accompanied by elevated IL-17A level and reduced immunofluorescence intensity of FLG and LOR proteins (P<0.05). The model group mice showed papules or pustules at the skin modeling site with progressively worsening desquamation under multifunctional skin imaging system. OCT revealed focal epidermal protrusions, blurred epidermal-dermal boundaries, and disorganized structural layers. HE staining showed significant epidermal hyperkeratosis and incomplete keratinization in the skin, with keratin plug formation in hair follicles and glandular lumens, thickened stratum corneum, hyperplasia of the stratum spinosum, as well as dense dermal inflammatory cell infiltration, and capillary dilation. Compared to the model group, both the minocycline group and the PYF group showed a reduced difference in body weight before and after experiment (P<0.05). On day 4 and 6, the TEWL value decreased, and water content of the skin stratum corneum increased (P<0.05); on day 6, the IL-17A level in the skin lesions decreased and immunofluorescence intensity of FLG and LOR proteins increased (P<0.05). On day 4 and 6, the severity of the skin lesions and range of redness and swelling were lighter than those in the model group, with reverted epidermal thickness, smoother surface and clearer epidermis-dermis boundary. HE staining showed that the degree of skin keratinization was reduced, and the inflammatory infiltration and vascular dilation in the dermis were improved compared to the model group. The PYF group showed better results than the minocycline group in reducing TEWL value on day 4 (P<0.05). ConclusionPYF may improve inflammation and skin barrier damage by downregulating IL-17A levels in lesion tissue and increasing skin barrier-related proteins, which could be one of the potential mechanism of action on acne.

ObjectiveTo observe the clinical efficacy and safety of Yishen Jiangtang decoction combined with conventional Western medicine treatment in managing stage G3A3 diabetic kidney disease (DKD) in the patients with the pattern of Qi-Yin deficiency combined with dampness-heat and blood stasis, and to explore its mechanism of inhibiting the endoplasmic reticulum stress (ERS)-apoptosis axis and delaying renal fibrosis (RF). MethodsA single-center, randomized, parallel-controlled clinical trial was conducted. A total of 78 patients diagnosed with stage G3A3 DKD and traditional Chinese medicine (TCM) pattern of Qi-Yin deficiency combined with dampness-heat and blood stasis and treated in the Department of Nephrology and the Department of Endocrinology of the People's Hospital Affiliated to Fujian University of Traditional Chinese Medicine from March 2025 to February 2026 were enrolled. They were randomly assigned at a 1∶1 ratio into a control group (conventional Western medicine treatment) and an experimental group (Yishen Jiangtang decoction combined with conventional Western medicine treatment), with 39 patients in each group. The treatment lasted for 12 weeks. Basic demographic data and medical history were collected before and after treatment. The two groups before and after treatment were compared in terms of the following parameters: Blood urea nitrogen (BUN), serum creatinine (SCr), estimated glomerular filtration rate (eGFR), urinary albumin-to-creatinine ratio (UACR), fasting blood glucose (FBG), triglycerides (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C). Enzyme-linked immunosorbent assay (ELISA) kits were used to measure serum glucose-regulated protein 78 (GRP78), serum cysteinyl aspartate-specific protease-3 (Caspase-3), and serum and urinary transforming growth factor-β1 (TGF-β1) levels before and after treatment. TCM symptom scores, TCM syndrome efficacy, and overall clinical efficacy were evaluated before and after treatment. Spearman correlation analysis was performed to explore the correlations of serum levels of GRP78 and Caspase-3, as well as serum and urinary levels of TGF-β1, with renal function, proteinuria, and glucose and lipid metabolism indicators in patients with DKD. In addition, safety indicators were also monitored. ResultsA total of 75 patients completed the study (38 in the control group and 37 in the experimental group). ① Baseline data: The two groups were comparable in terms of sex and age, with no statistically significant difference. ② Efficacy outcomes: Compared with baseline levels, both groups showed reductions in BUN, SCr, UACR, FBG, TG, TC, LDL-C, and TCM symptom scores (P<0.01) and increases in eGFR level (P<0.01). Moreover, the experimental group outperformed the control group in altering the indicators above (P<0.05). Regarding TCM syndrome efficacy, the total response rate in the experimental group was 83.78%, which was higher than that (57.89%) in the control group (P<0.05). Regarding overall clinical efficacy, the total response rate in the experimental group was 78.38%, which was higher than that (50.00%) in the control group (P<0.05). ③ Mechanism outcomes: Compared with baseline levels, both groups showed declined serum levels of GRP78, Caspase-3, and TGF-β1 and urinary level of TGF-β1 after treatment (P<0.01). Moreover, the experimental group showed greater declines than the control group (P<0.05). The serum levels of GRP78, Caspase-3,and TGF-β1 and the urinary level of TGF-β1 in DKD patients showed positive correlations with BUN, SCr, UACR, and FBG and negative correlations with eGFR (P<0.05). ④ Safety outcomes: Neither group showed drug-related adverse reactions, and laboratory safety parameters remained within normal ranges. ConclusionYishen Jiangtang decoction combined with conventional Western medicine treatment may safely and effectively alleviate clinical symptoms, correct glucose and lipid metabolism disorders, and protect the renal function in patients with stage G3A3 DKD and the pattern of Qi-Yin deficiency combined with dampness-heat and blood stasis. The mechanism may be associated with inhibition of the ERS-apoptosis axis and delay of the RF process.

ObjectiveTo establish a semi-automated workflow for hyoid motion tracking based on submental ultrasound videos, evaluate the reliability of manual measurements and the validity of semi-automated tracking, and compare the analytical efficiency. MethodsA total of 46 healthy adults were recruited at Xiamen Fifth Hospital from October, 2024 to August, 2025, and performed dry swallows and swallows of 5 mL and 10 mL moderately-thick liquid boluses. A total of 414 sagittal-plane submental ultrasound videos were acquired. After video quality screening and tracking quality-control procedures, 286 videos were included for paired analysis. A semi-automated tracking pipeline was constructed combining the channel-and-spatial-reliability tracker and You Only Look Once version 8 small (YOLO v8s). Intra-class correlation coefficients [ICC(A,1)] based on the absolute-agreement single-measurement model were calculated for test-retest and inter-rater manual measurements. Using the manual repeated-measurement results as the reference standard, Pearson correlation coefficient (r), ICC(A,1) and concordance correlation coefficient (CCC) were computed for the semi-automated measurements. A total of 5 000 subject-clustered bootstrap resamples were performed to calculate 95% confidence intervals. Cumulative analysis time of manual and semi-automated workflows was compared. ResultsFor the independent test set of YOLOv8s, precision and recall reached 0.940 and 0.956. The mean average precision was 0.974 at an intersection-over-union threshold of 0.5, and 0.609 averaged across thresholds ranging from 0.5 to 0.95. For manual measurements of maximum horizontal and vertical hyoid displacement, the test-retest ICC(A,1) values were 0.925 and 0.912, respectively; the inter-rater ICC(A,1) values were 0.815 and 0.775. For semi-automated versus manual reference measurements, r = 0.865,ICC(A,1) = 0.843,CCC = 0.843 in maximum horizontal displacement; and r = 0.754,ICC(A,1) = 0.746,CCC = 0.745 in maximum vertical displacement. Mean biases were -0.772 mm and -0.229 mm, with 95% limits of agreement of -4.567 to 3.023 mm and -2.918 to 2.460 mm for horizontal and vertical directions. Cumulative manual analysis time was 526 minutes for rater A and 713 minutes for rater B. The semi-automated workflow consumed 155 minutes, in which 40 minutes for computational processing and 115 minutes for manual review. ConclusionManual measurement of maximum hyoid displacement is reliable using qualified submental ultrasound videos. Semi-automated tracking achieves acceptable agreement with manual reference and greatly reduces analysis workload.

BACKGROUND:Osteoporotic fracture is the most serious complication of osteoporosis.Previous studies have demonstrated that gut microbiota has a regulatory effect on skeletal tissue and that gut microbiota has an important relationship with osteoporotic fracture,but the causal relationship between the two is unclear. OBJECTIVE:To explore the causal relationship between gut microbiota and osteoporotic fractures using Mendelian randomization method. METHODS:The genome-wide association study(GWAS)datasets of gut microbiota and osteoporotic fracture were obtained from the IEU Open GWAS database and the Finnish database R9,respectively.Using gut microbiota as the exposure factor and osteoporotic fracture as the outcome variable,Mendelian randomization analyses with random-effects inverse variance weighted,MR-Egger regression,weighted median,simple model,and weighted model methods were performed to assess whether there is a causal relationship between gut microbiota and osteoporotic fracture.Sensitivity analyses were performed to test the reliability and robustness of the results.Reverse Mendelian randomization analyses were performed to further validate the causal relationship identified in the forward Mendelian randomization analyses. RESULTS AND CONCLUSION:The results of this Mendelian randomization analysis indicated a causal relationship between gut microbiota and osteoporotic fracture.Elevated abundance of Actinomycetales[odds ratio(OR)=1.562,95%confidence interval(CI):1.027-2.375,P=0.037),Actinomycetaceae(OR=1.561,95%CI:1.027-2.374,P=0.037),Actinomyces(OR=1.544,95%CI:1.130-2.110,P=0.006),Butyricicoccus(OR=1.781,95%CI:1.194-2.657,P=0.005),Coprococcus 2(OR=1.550,95%CI:1.068-2.251,P=0.021),Family ⅩⅢ UCG-001(OR=1.473,95%CI:1.001-2.168,P=0.049),Methanobrevibacter(OR=1.274,95%CI:1.001-1.621,P=0.049),and Roseburia(OR=1.429,95%CI:1.015-2.013,P=0.041)would increase the risk of osteoporotic fractures in patients.Elevated abundance of Bacteroidia(OR=0.660,95%CI:0.455-0.959,P=0.029),Bacteroidales(OR=0.660,95%CI:0.455-0.959,P=0.029),Christensenellacea(OR=0.725,95%CI:0.529-0.995,P=0.047),Ruminococcaceae(OR=0.643,95%CI:0.443-0.933,P=0.020),Enterorhabdus(OR=0.558,95%CI:0.395-0.788,P=0.001),Eubacterium rectale group(OR=0.631,95%CI:0.435-0.916,P=0.016),Lachnospiraceae UCG008(OR=0.738,95%CI:0.546-0.998,P=0.048),and Ruminiclostridium 9(OR=0.492,95%CI:0.324-0.746,P=0.001)would reduce the risk of osteoporotic fractures in patients.We identified 16 gut microbiota associated with osteoporotic fracture by the Mendelian randomization method.That is,using gut microbiota as the exposure factor and osteoporotic fracture as the outcome variable,eight gut microbiota showed positive causal associations with osteoporotic fracture and another eight gut microbiota showed negative causal associations with osteoporotic fracture.The results of this study not only identify new biomarkers for the early prediction of osteoporotic fracture and potential therapeutic targets in clinical practice,but also provide an experimental basis and theoretical basis for the study of improving the occurrence and prognosis of osteoporotic fracture through gut microbiota in bone tissue engineering.
