Background Work-related musculoskeletal disorders (WMSDs), as one of the major occupational health issues worldwide, have shown an increasing positive rate year by year. Due to the unique demands of work, operating room nurses exhibit a higher positive rate of WMSDs compared to other occupational groups, necessitating active attention and intervention. Objective To estimate the prevalence of WMSDs among operating room nurses in tertiary hospitals, explore the characteristics and latent categories of WMSDs, and analyze the influencing factors associated with the occurrence of WMSDs. Method Using a randomized cluster sampling method, operating room nurses from nine tertiary hospitals in Urumqi were selected as study participants between December 2023 and January 2024. Data were collected through a general information questionnaire, an ergonomic questionnaire for operating room nurses, and the Chinese Musculoskeletal Disorders Questionnaire. Latent class analysis was employed to examine the patterns of WMSDs among the nurses, while chi-square test and multinomial logistic regression were utilized to analyze the influencing factors of WMSDs. Result A total of 411 valid questionnaires were collected in this survey. The positive rate of WMSDs among operating room nurses in the tertiary hospitals of Urumqi over the past year was 91.9%. The positive rates, ordered from highest to lowest by body region, were neck (79.1%), shoulders (70.3%), and lower back (68.1%). The operating room nurses were categorized into three distinct groups by latent class analysis: multi-site pain group, neck-shoulder-back pain group, and neck and lower back pain group. The results of the multinomial logistic regression models revealed that gender, job strain level, ergonomic load level in the operating room, and exposure to cold or drafty working conditions or not were significant influencing factors for reporting WMSDs among operating room nurses. Specifically, having less than 5 years of work experience, low ergonomic load level, low job strain, and moderate job strain were identified as protective factors against WMSDs. Conversely, exposure to cold or drafty working environments and being female were identified as risk factors for WMSDs. The logistic regression models also indicated that compared to the neck-lower back pain group, the neck-shoulder-back pain group had a higher probability of reporting low job strain (OR=0.168, 95%CI: 0.029, 0.968) and being female (OR=4.847, 95%CI: 2.506, 9.378). In contrast, when comparing to the neck-lower back pain group, the multi-site pain group had a higher probability of reporting, low-level ergonomic workload (OR=0.079, 95%CI: 0.015, 0.412), low job strain (OR=0.019, 95%CI: 0.002, 0.145), moderate job strain (OR=0.080, 95%CI: 0.016, 0.401), high job strain (OR=0.132, 95%CI: 0.027, 0.647), less than 5 years of work experience (OR=0.173, 95%CI: 0.044, 0.683), being female (OR=2.424, 95%CI: 1.130, 5.200), and exposure to cold or drafty working environments (OR=3.277, 95%CI: 1.657, 6.481). Conclusion The positive rate WMSDs among operating room nurses in tertiary hospitals is notably high in Urumqi, with distinct co-occurrence characteristics observed within the population. To mitigate the risk of WMSDs, it is essential to implement targeted health education and prevention training programs tailored to different patterns of WMSDs. Additionally, improving working conditions, optimizing human resource allocation , and other proactive measures should be undertaken. These efforts will effectively reduce the incidence of WMSDs among operating room nurses and safeguard their occupational health.

ObjectiveTo investigate the ameliorative effect of Xingpi capsules on functional dyspepsia(FD) and the potential mechanism. MethodsSixty SPF-grade male SD neonatal rats(7 days old) were randomly divided into the normal group(n=12) and the modeling group(n=48), and the FD model was prepared by iodoacetamide gavage in the modeling group. After the model was successfully prepared, the rats in the modeling group were randomly divided into the model group, the low-dose and high-dose groups of Xingpi capsules(0.135, 0.54 g·kg-1) and the domperidone group(3 mg·kg-1), with 12 rats in each group. Rats in the normal and model groups were gavaged with distilled water, and rats in the rest of the groups were gavaged with the corresponding medicinal solution, once a day for 7 d. The general survival condition of the rats was observed, and the water intake and food intake of the rats were measured, the gastric emptying rate and the small intestinal propulsion rate were measured at the end of the treatment, the pathological damage of the rat duodenum was examined by hematoxylin-eosin(HE) staining, and the expressions of colonic tight junction protein(Occludin) and zonula occludens protein-1(ZO-1) were detected by immunofluorescence. The differentially expressed genes in the duodenal tissues of the model group and the normal group, and the high-dose group of Xingpi capsules and the model group were detected by transcriptome sequencing after the final administration, and Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analyses were carried out. The transcriptomic results were validated by Western blot, immunofluorescence, and real-time fluorescence quantitative polymerase chain reaction(Real-time PCR), and the active ingredients of Xingpi capsules were screened for molecular docking with the key targets. ResultsCompared with the normal group, the general survival condition of rats in the model group was poorer, and the water intake, food intake, gastric emptying rate and small intestinal propulsion rate were all significantly reduced(P<0.05), inflammatory infiltration was seen in duodenal pathology, and the fluorescence intensities of Occludin and ZO-1 in the colon were significantly reduced(P<0.01). Compared with the model group, the general survival condition of rats in the high-dose group of Xingpi capsules improved significantly, and the water intake, food intake, gastric emptying rate and small intestinal propulsion rate were all significantly increased(P<0.05), the duodenal pathology showed a decrease in inflammatory infiltration, and the fluorescence intensities of colonic Occludin and ZO-1 were significantly increased(P<0.01). Transcriptomic results showed that Xingpi capsules might exert therapeutic effects by regulating the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt) through the key genes such as Slc5a1, Abhd6. The validation results showed that compared with the normal group, the phosphorylation levels of PI3K and Akt proteins, the protein expression level of interleukin(IL)-1β, and the fluorescence intensities of IL-6 and IL-1β were significantly increased in the model group(P<0.05, P<0.01), and the mRNA levels of Slc5a1, Abhd6, Mgam, Atp1a1, Slc7a8, Cdr2, Chrm3, Slc5a9 and other key genes were significantly increased(P<0.01). Compared with the model group, the phosphorylation levels of PI3K and Akt, the protein expression level of IL-1β and the fluorescence intensities of IL-6 and IL-1β in the high-dose group of Xingpi capsules were significantly reduced(P<0.05, P<0.01), and the mRNA levels of Slc5a1, Abhd6, Mgam, Atp1a1, Slc7a8, Cdr2, Chrm3 and Slc5a9 were significantly reduced(P<0.05). Weighted gene co-expression network analysis and molecular docking results showed that E-nerolidol and Z-nerolidol in Xingpi capsules were well bound to ABDH6 protein, and linarionoside A, valerosidatum and senkirkine were well bound to Slc5a1 protein. ConclusionXingpi capsules can effectively improve the general survival and gastrointestinal motility of FD rats, its specific mechanism may be related to the inhibition of PI3K/Akt signaling pathway to alleviate the low-grade inflammation of duodenum, and E-nerolidol, Z-nerolidol, linarionoside A, valerosidatum and senkirkine may be its key active ingredients.

As people's living standards improve, the development trend of diabetes has gradually become severe. Diabetes is a chronic inflammatory disease associated with abnormal expression of nuclear factor-kappa B (NF-κB) in patients. NF-κB exists in various tissue cells and participates in the regulation of a variety of genes related to immune function and inflammation. Varieties of factors can activate NF-κB when the body is stimulated by external factors, so as to produce inflammation and other reactions. Previous studies on NF-κB mainly focus on cancer, and the pathological mechanism of the treatment of diabetes by related signaling pathways and the progress of traditional Chinese medicine (TCM) treatment have not been systematically elaborated on. By referring to the relevant literature in China and abroad, it was found that NF-κB is not isolated in the development and progression of diabetes but is associated with signal molecules related to inflammation, oxidative stress, and energy metabolism, and it is involved in mediating inflammation, pancreatic β cell apoptosis, insulin signal transduction, and other physiological functions. Therefore, blocking the transmission of NF-κB signaling pathway is beneficial to the treatment of diabetes. At present, Western medicine for the treatment of diabetes mainly includes oral hypoglycemic drugs and insulin injections, but the adverse reactions are obvious. TCM has been characterized by multi-target, extensive action, and excellent curative effects in the treatment of diabetes. TCM and its compounds with functions of tonifying Qi and promoting blood circulation, regulating qi and eliminating phlegm, clearing heat and detoxifying, and nourishing Yin and moistening dryness can effectively intervene in the abnormal expression of NF-κB signaling pathway in vivo through anti-inflammatory effects. In this paper, the association between NF-κB signaling pathway and diabetes was summarized, and the modern research progress of TCM intervention of NF-κB signaling pathway in the treatment of diabetes in the past five years was reviewed, so as to lay a laboratory foundation for the study of a new pathological mechanism of diabetes based on NF-κB signaling pathway and provide new targets and research direction for the prevention and treatment of diabetes and development of related TCM.
