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 validate the therapeutic effect of Yinqi Sanhuang Jiedu decoction (YQSH) on a mouse model of carbon tetrachloride (CCl4)-induced liver fibrosis and to investigate its correlations with the Piezo-type mechanosensitive ion channel component 1 (Piezo1)-Yes-associated protein (YAP) mechanical signaling axis and macrophage polarization. MethodsFifty-four C57BL/6J mice were randomized into a blank control group, a 4-week model group, a 6-week model group, a 8-week model group, a positive drug (silymarin, 55 mg·kg-1·d-1) group, and low-, medium-, and high-dose (8.325, 16.65, 33.3 g·kg-1·d-1, respectively) YQSH groups. Except the 6-week model group (n=12), each of the other groups had 6 mice. Mice in other groups except the blank control group received intraperitoneal injections of 10% CCl4 twice weekly for the modeling of liver fibrosis. Drug interventions began one week after the initial modeling through gavage, and the blank control and model groups received 0.2 mL of normal saline via gavage. The histopathological changes and collagen deposition in the liver were observed via hematoxylin-eosin (HE), Masson's trichrome, and Sirius red staining. Serum activities of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), as well as serum levels of total protein (TP), albumin (ALB), total bilirubin (TBIL), hyaluronic acid (HA), laminin (LN), procollagen type Ⅲ (PCⅢ), and collagen type Ⅳ (Ⅳ-C), were measured. The levels of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in the liver tissue were determined by enzyme-linked immunosorbent assay (ELISA). The protein and mRNA levels of Piezo1 and YAP1 in the liver tissue were determined by immunohistochemistry (IHC) and Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR), respectively. Co-localization of Piezo1 with YAP1, and YAP1 with inducible nitric oxide synthase (iNOS) was observed by the immunofluorescence (IF) assay. The proportions of M1-type (F4/80+CD80+) and M2-type (F4/80+CD206+) macrophages in the liver tissue were examined by flow cytometry. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses and gene set enrichment analysis (GSEA) were performed through transcriptomic sequencing. ResultsCompared with the blank control group, the model group exhibited gradually worsened liver fibrosis at the 4th, 6th, and 8th weeks. The 6- and 8-week model groups showcased inflammatory cell infiltration and collagen deposition in the liver (P<0.01) and upregulated protein levels of both Piezo1 and YAP1 (P<0.01). Compared with the model groups, treatment with YQSH improved the liver function (P<0.05, P<0.01), alleviated liver fibrosis (P<0.05, P<0.01), and reduced intrahepatic inflammatory cell infiltration and collagen deposition (P<0.01). Furthermore, the treatment downregulated the protein and mRNA levels of Piezo1 and YAP1 (P<0.05, P<0.01), lowered the levels of inflammatory factors TNF-α and IL-1β (P<0.05, P<0.01), and decreased the ratio of CD80 (M1-type)/CD206 (M2-type) macrophage proteins (P<0.01). The IF assay showed co-localization of YAP1 with Piezo1 and iNOS. Compared with the model groups, YQSH treatment downregulated the expression of Piezo1, YAP1, and iNOS (P<0.05, P<0.01). Transcriptomic analysis suggested that the anti-liver fibrosis effect of YQSH may be related to the Hippo signaling pathway (P<0.05). ConclusionThe anti-liver fibrosis effect of YQSH may be related to its inhibition of the Piezo1-YAP signaling axis and regulation of macrophage polarization.

ObjectiveTo investigate the effects of Hei Xiaoyaosan on neuroinflammation in APP/PS1 mice and decipher the mechanism based on the C-X3-C chemokine ligand 1 (CX3CL1)-CX3CL1 receptor 1 (CX3CR1) signaling axis. MethodsSixty 16-week-old male APP/PS1 mice were selected and acclimatized for one week, and they were then randomly allocated into a model group, a CX3CL1 group (bilateral hippocampal injection of CX3CL1 at 0.5 g·L-1), and high-, medium-, and low-dose (22.10, 11.05, and 5.53 g·kg-1, respectively) Hei Xiaoyaosan groups, with 12 mice in each group. Twelve age-matched male C57BL/6J mice served as the blank group (bilateral hippocampal injection of an equal volume of PBS). The high-, medium-, and low-dose Hei Xiaoyaosan groups received corresponding drugs via gavage, while the blank group received an equal volume of normal saline, with an intervention period of 90 days. Morris water maze was used to assess learning and memory abilities. Nissl staining was performed to observe the pathological changes in neurons of the hippocampal CA1 region. Immunohistochemistry was adopted to detect amyloid-β1-42 (Aβ1-42) deposition in the hippocampal CA1 region. The immunofluorescence assay was employed to detect the expression of M1 and M2 microglial markers, including cluster of differentiation 86 (CD86)/ionized calcium-binding adapter molecule 1 (Iba-1) and arginase-1 (Arg1)/Iba1. Enzyme-linked immunosorbent assay (ELISA) was employed to measure the levels of interleukin-8 (IL-8) and interleukin-13 (IL-13) in the hippocampal tissue. Western blot was employed to determine the protein levels of CX3CL1, CX3CR1, CREB-binding protein (CBP), cyclic AMP response element-binding protein (CREB), phosphorylated (p)-CREB, and brain-derived neurotrophic factor (BDNF) in the hippocampal tissue. ResultsCompared with the blank group, the model group exhibited prolonged escape latency on day 5 and a reduced swimming distance in the target quadrant (P<0.01), disarrangement of hippocampal neurons, with a reduced number of cells and uneven Nissl body staining, increased CD86/Iba1 expression, decreased Arg1/Iba1 expression (P<0.01), enhanced Aβ expression (P<0.01), an elevated IL-8 level and a declined IL-13 level (P<0.01), and downregulated protein levels of CX3CL1, CX3CR1, CBP, p-CREB, and BDNF (P<0.01). Compared with the model group, all treatment groups showed shortened escape latency on day 5 and an increased swimming distance in the target quadrant (P<0.05, P<0.01), regular arrangement of neurons with an increased number and increased Nissl bodies, reduced CD86/Iba1 expression, increased Arg1/Iba1 and decreased Aβ expression (P<0.01), and a declined IL-8 level and an elevated IL-13 level (P<0.05, P<0.01). In the CX3CL1 group and the high- and medium-dose Hei Xiaoyaosan groups, the relative expression levels of CX3CL1, CX3CR1, CBP, and p-CREB were upregulated (P<0.01). In the low-dose Hei Xiaoyaosan group, the relative expression levels of CX3CL1, CX3CR1, CBP, p-CREB/CREB, and BDNF were upregulated (P<0.05, P<0.01). ConclusionHei Xiaoyaosan can improve learning and cognitive abilities in APP/PS1 mice. Specifically, it may regulate the CX3CL1/CX3CR1 signaling axis to activate the CREB/BDNF signaling pathway for the subsequent release of BDNF, modulation of microglial polarization, reduction of inflammatory cytokine levels, and attenuation of Aβ deposition.

ObjectiveMicrotube associated protein-2 (MAP-2), alpha-tubulin (α-tubulin), and synaptophysin (SYP) are important proteins in neuronal signal communication. This paper observed the effects of modified Zhigancao Tang on the expression of serum α-Synuclein (α-Syn) and its oligomers, MAP-2, α-tubulin, and SYP of patients with liver and kidney deficiency of Parkinson's disease (PD), analyzed their correlation, and evaluated the therapeutic effect of modified Zhigancao Tang in patients with liver and kidney deficiency of PD based on α-Syn transmission pathway mediated by neuronal communication in vivo. MethodsA total of 60 patients with PD who met the inclusion criteria were randomly divided into a treatment group (30 cases) and a control group (30 cases). Both groups were treated on the basis of PD medicine, and the treatment group was treated with modified Zhigancao Tang. Both groups were treated for 12 weeks. The changes in UPDRS score, TCM syndrome score, and expression of serum α-Syn and its oligomers, MAP-2, α-tubulin, and SYP were observed before and after 12 weeks of treatment in each group. The correlation between the above-mentioned serum biological indexes and the levels of serum α-Syn and its oligomers was analyzed. ResultsAfter treatment, the TCM syndrome score, UPDRS score, UPDRS-Ⅱ score, and UPDRS-Ⅲ score of the treatment group were significantly decreased (P<0.05, P<0.01). The UPDRS score, UPDRS-Ⅱ score, and UPDRS-Ⅲ scores in the treatment group were significantly decreased compared with those in the control group after treatment (P<0.05). After treatment, the total effective rate of the control group was 63.3% (19/30), and that of the treatment group was 86.7% (26/30). The clinical effect of the observation group was better than the control group (Z=-2.03, P<0.05). The total effective rate of the observation group was better than that of the control group, and the difference was statistically significant (χ2=5.136, P<0.05). After treatment, the oligomer level of serum α-Syn and MAP-2 level in the treatment group were significantly decreased (P<0.05, P<0.01). The levels of serum α-Syn and its oligomers, as well as α-tubulin in the treatment group, were significantly decreased compared with those in the control group after treatment (P<0.05, P<0.01). Serum α-Syn was correlated with serum MAP-2 and α-Syn oligomer in patients with PD (P<0.05, P<0.01) but not correlated with serum SYP . Serum α-Syn oligomers of patients with PD were correlated with serum MAP-2 and α-tubulin (P<0.05, P<0.01) but not correlated with serum SYP level. Serum SYP of patients with PD was correlated with serum MAP-2 (P<0.05). ConclusionModified Zhigancao Tang has a therapeutic effect on patients with liver and kidney deficiency of PD by inhibiting the production of α-Syn oligomers and intervening α-Syn microtubule transport pathway in vivo.

Based on the holistic view of "spleen-vessels-heart-spirit" system, this article explores the pathogenesis and progression of atrial fibrillation. It is proposed that the onset of atrial fibrillation is due to failure of the spleen to transport and disharmony of blood vessels; phlegm and blood stasis obstructing the collaterals and damage to the heart structure are the basis of its pathogenesis; the unclear mind and disorder of body and spirit are the causes of its progression. Based on the characteristics of pathological changes in different stages of the disease, it is proposed that early treatment should focus on restoring the middle jiao, clearing and promoting blood vessels, using modified Yigong Powder (异功散); during the progression of the disease, treatment should remove blood stasis and phlegm, nourish heart and protect the pulse, using self-prescribed modified Mengshi Tongmai Decoction (礞石通脉汤); meanwhile, calming mind and stabilizing palpitations, and regulating spirit should be sequentially incorporated, with self-prescribed Jiazao Ningmai Decoction (甲枣宁脉汤) or Shenying Dingji Decoction (参英定悸汤) and modified as appropriate. Clinical treatment should focus on the whole disease course of atrial fibrillation, implementing stage-based treatments to enable early intervention and holistic regulation.

Objective:To investigate the effects of the Epley and Semont procedures with varying lateral angles of the head on posterior semicircular canal benign paroxysmal positional vertigo (PC-BPPV). Methods:A total of 115 patients with unilateral PC-BPPV were randomly divided into five groups: Epley group, Semont group, Semont+10° group, Semont+20° group, and Semont+30° group, with 23 patients in each group. Corresponding reduction treatments were performed. Results:The total effective rates for the Epley group, Semont group, Semont+10° group, Semont+20° group, and Semont+30° group were 95.7% (22/23), 4.3% (1/23), 30.4% (7/23), 52.2% (12/23), and 87.0% (20/23) respectively. The inefficiencies were 4.3% (1/23), 95.7% (22/23), 69.6% (16/23), 47.8% (11/23), and 13.0% (3/23). Statistically significant differences were observed in the total effective rates among the five groups (χ²=54.11, P<0.01). The total effective rates in the Semont group, Semont+10° group, and Semont+20° group were significantly different from that of the Epley group (P<0.01), while no statistically significant difference was found between the Semont+30° group and the Epley group (P= 0.608>0.012 5). Conclusion:Among the four Semont methods with different lateral lying angles, the total effective rate of reduction treatment increased with the elevation of the lateral lying angle on the affected side. The efficacy of the Semont+30° group in treating PC-BPPV was not significantly different from the Epley group's reduction effect, which was markedly superior to that of the other four Semont methods at different angles. Therefore, the Semont+30° reduction technique is recommended for the treatment of PC-BPPV.
