PURPOSE: To investigate the incidence and influencing factors of bone loss in patients with spinal cord injury (SCI). METHODS: A retrospective case-control study was conducted. Patients with SCI in our hospital from January 2019 to March 2023 were collected. According to the correlation between bone mineral density (BMD) at different sites, the patients were divided into the lumbar spine group and the hip joint group. According to the BMD value, the patients were divided into the normal bone mass group (t > -1.0 standard deviation) and the osteopenia group (t ≤ -1.0 standard deviation). The influencing factors accumulated as follows: gender, age, height, weight, cause of injury, injury segment, injury degree, time after injury, start time of rehabilitation, motor score, sensory score, spasticity, serum value of alkaline phosphatase, calcium, and phosphorus. The trend chart was drawn and the influencing factors were analyzed. SPSS 26.0 was used for statistical analysis. Correlation analysis was used to test the correlation between the BMD values of the lumbar spine and bilateral hips. Binary logistic regression analysis was used to explore the influencing factors of osteoporosis after SCI. p < 0.05 was considered statistically significant. RESULTS: The incidence of bone loss in patients with SCI was 66.3%. There was a low concordance between bone loss in the lumbar spine and the hip, and the hip was particularly susceptible to bone loss after SCI, with an upward trend in incidence (36% - 82%). In this study, patients with SCI were divided into the lumbar spine group (n = 100) and the hip group (n = 185) according to the BMD values of different sites. Then, the lumbar spine group was divided into the normal bone mass group (n = 53) and the osteopenia group (n = 47); the hip joint group was divided into the normal bone mass group (n = 83) and the osteopenia group (n = 102). Of these, lumbar bone loss after SCI is correlated with gender and weight (p = 0.032 and < 0.001, respectively), and hip bone loss is correlated with gender, height, weight, and time since injury (p < 0.001, p = 0.015, 0.009, and 0.012, respectively). CONCLUSIONS The incidence of bone loss after SCI was high, especially in the hip. The incidence and influencing factors of bone loss in the lumbar spine and hip were different. Patients with SCI who are male, low height, lightweight, and long time after injury were more likely to have bone loss.

BACKGROUND: It is inaccurate to reflect the level of dust exposure through working years. Furthermore, identifying a predictive indicator for lung function decline is significant for coal miners. The study aimed to explored whether club cell secretory protein (CC16) levels can reflect early lung function changes. METHODS: The cumulative respiratory dust exposure (CDE) levels of 1,461 coal miners were retrospectively assessed by constructed a job-exposure matrix to replace working years. Important factors affecting lung function and CC16 were selected by establishing random forest models. Subsequently, the potential of CC16 to reflect lung injury was explored from multiple perspectives. First, restricted cubic spline (RCS) models were used to compare the trends of changes in lung function indicators and plasma CC16 levels after dust exposure. Then mediating analysis was performed to investigate the role of CC16 in the association between dust exposure and lung function decline. Finally, the association between baseline CC16 levels and follow-up lung function was explored. RESULTS: The median CDE were 35.13 mg/m³-years. RCS models revealed a rapid decline in forced vital capacity (FVC), forced expiratory volume in the first second (FEV₁), and their percentages of predicted values when CDE exceeded 25 mg/m³-years. The dust exposure level (<5 mg/m³-years) causing significant changes in CC16 was much lower than the level (25 mg/m³-years) that caused changes in lung function indicators. CC16 mediated 11.1% to 26.0% of dust-related lung function decline. Additionally, workers with low baseline CC16 levels experienced greater reductions in lung function in the future. CONCLUSIONS CC16 levels are more sensitive than lung indicators in reflecting early lung function injury and plays mediating role in lung function decline induced by dust exposure. Low baseline CC16 levels predict poor future lung function.

Objective:To discuss the regulatory role of complement alternative pathway in mouse colorectal cancer(CRC)liver metastasis model based on bioinformatics methods,and to clarify its mechanism through experimental verification.Methods:Using"CRC liver metastasis"as the keyword,the GSE81558 dataset was retrieved from Gene Expression Omnibus(GEO)database,including normal colon tissue samples,CRC tissue samples and CRC liver metastasis tissue samples.Bioinformatics methods were used to analyze and screen differentially expressed genes(DEGs).Gene Ontology(GO)functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis were performed using R and Cytoscape software,and the results were visualized.Search Tool for the Retrieval of Interacting Genes/Proteins(STRING)database was used to evaluate protein-protein interactions(PPIs)of DEGs and construct PPI network.Twelve C57BL/6 mice were injected with SL4 tumor cells into spleen,and the liver tissues were collected at 0,7 and 14 d.Real-time fluorescence quantitative PCR(RT-qPCR)method was used to detect the expression levels of complement pathway-related genes in liver metastatic foci.The CRC liver metastasis mouse model was used to verify the complement signaling pathway.The mice were divided into control group,factor B knockout group(FB-/-)and C4 factor knockout group(C4-/-),and there were 6 mice in each group.The liver weights of the mice were measured;HE staining was used to detect the percentage of metastatic area in liver tissue in control group and FB-/-group;immunohistochemistry was used to detect macrophage infiltration in liver tissue in control group and FB-/-group,and the percentage of macrophage infiltration was calculated.Results:The distances between normal colon tissue samples and CRC tissue samples,as well as between CRC tissue samples and CRC liver metastasis tissue samples were far,indicating significant differences between samples,allowing subsequent analysis of DEGs.A total of 1 908 DEGs were screened in the dataset comparing normal colon tissue samples and CRC tissue samples,including 771 up-regulated DEGs and 1 137 down-regulated DEGs.Twenty-three up-regulated DEGs and 100 down-regulated DEGs were identified in the dataset comparing CRC and CRC liver metastasis.The GO functional enrichment analysis results showed that compared with normal colon tissue samples,DEGs in CRC samples were mainly enriched in biological processes(BP)related to cell cycle and mitosis,including mitotic cell cycle process,cell division,response to hormone,mitotic nuclear division and response to lipid.Compared with CRC samples,the DEGs in CRC liver metastasis samples were mainly enriched in coagulation-related BP,including platelet degranulation,blood coagulation regulation,acute-phase response,hemostasis regulation and coagulation regulation.The KEGG pathway enrichment analysis results showed that compared with normal colon tissue samples,the DEGs in CRC tissue samples were mainly enriched in cell cycle and p53 signaling pathways.Compared with CRC tissue samples,the DEGs in CRC liver metastasis tissue samples were mainly enriched in complement,coagulation cascade and metabolism-related signaling pathways.The Hub genes identified in PPI network were related to blood proteins.The RT-qPCR results showed that compared with 0 d group,the mRNA expression level of complement related genes complement 1q(C1q)in liver metastatic foci tissue sampres in 7 d group was significantly decreased(P<0.05),the mRNA expression levels of complement 3(C3),complement 5(C5),FB,and factor D(FD)were significantly increased(P<0.05 or P<0.01),the mRNA expression levels of complement pathway-related genes C1q,complement 2(C2),C3,complement fragment 3a receptor(C3aR),C5,complement fragment 5a receptor(C5aR),decay-accelerating factor(DAF),FB and FD in liver metastatic foci tissue sampres in 14 d group were significantly increased(P<0.05 or P<0.01).Compared with control group,the liver weight of the mice in FB-/-group was significantly decreased(P<0.01),while there was no significant difference was observed in C4-/-group(P>0.05).The HE staining results showed that compared with control group,the liver metastatic foci in FB-/-mice were significantly decreased,and the percentage of metastatic area was decreased(P<0.01).The immunohistochemistry results showed that compared with control group,the macrophage infiltration in liver metastatic foci of the mice in FB-/-group was reduced,and the percentage of macrophage infiltration was decreased(P<0.01).Conclusion:Complement cascade is associated with CRC liver metastasis,and the alternative complement pathway regulates CRC liver metastasis,suggesting this pathway may serve as a potential therapeutic target for CRC liver metastasis.

Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

Pathological vascular remodeling is a hallmark of various vascular diseases. Previous research has established the significance of andrographolide in maintaining gastric vascular homeostasis and its pivotal role in modulating endothelial barrier dysfunction, which leads to pathological vascular remodeling. Potassium dehydroandrographolide succinate (PDA), a derivative of andrographolide, has been clinically utilized in the treatment of inflammatory diseases precipitated by viral infections. This study investigates the potential of PDA in regulating pathological vascular remodeling. The effect of PDA on vascular remodeling was assessed through the complete ligation of the carotid artery in C57BL/6 mice. Experimental approaches, including rat aortic primary smooth muscle cell culture, flow cytometry, bromodeoxyuridine (BrdU) incorporation assay, Boyden chamber cell migration assay, spheroid sprouting assay, and Matrigel-based tube formation assay, were employed to evaluate the influence of PDA on the proliferation and motility of smooth muscle cells (SMCs). Molecular docking simulations and co-immunoprecipitation assays were conducted to examine protein interactions. The results revealed that PDA exacerbates vascular injury-induced pathological remodeling, as evidenced by enhanced neointima formation. PDA treatment significantly increased the proliferation and migration of SMCs. Further mechanistic studies disclosed that PDA upregulated myeloid differentiation factor 88 (MyD88) expression in SMCs and interacted with T-cadherin (CDH13). This interaction augmented proliferation, migration, and extracellular matrix deposition, culminating in pathological vascular remodeling. Our findings underscore the critical role of PDA in the regulation of pathological vascular remodeling, mediated through the MyD88/CDH13 signaling pathway.

To establish a method for determining 26 inorganic elements in earthworm polypeptide and determine the elemental content in different batches of earthworm polypeptide, microwave digestion method was used to pre-treat the samples, and ICP-MS method was used to determine the content of 26 elements in different batches of earthworm polypeptide. The linear relationships of 26 elements were good in the range of 0-1 000 μg·L^-1, with R² greater than 0.999, precision RSD 0.21%-2.71%, repeatability RSD 0.19%-4.69%, stability RSD 0.11%-4.24%, and recovery rates of 82.41%-116.16%. The data was plotted using Origin 2022 software to characterize the distribution of elements content. SPSS 27.0 was used for principal component analysis, and SIMCA 14.1 software was used for OPLS-DA analysis. The results showed that among the 26 elements, the higher content of earthworm polypeptide was K, Na, and Ca, followed by Zn, Fe, Al, B and other trace elements, In, Sc, Co, Pb, Bi and other elements had little or no detectable content, and there were differences in the content of polypeptide in different batches. This study provides a theoretical basis for the production quality control, quality evaluation and drug efficacy application of earthworm polypeptide through the determination and analysis of the elements and content of earthworm polypeptide.
