Background Personal protection is crucial for reducing the risk of zoonotic pathogen infection among livestock workers. Investigating the current status of its implementation and associated influencing factors can provide empirical evidence for developing more effective intervention measures. Objective To investigate the current status of personal protection implementation among livestock workers in Xinjiang, China and its influencing factors, providing a reference for formulating targeted intervention measures. Methods This study was conducted in Bayingolin Mongol Autonomous Prefecture, Kashgar region, and the First and Eighth Divisions of Xinjiang Production and Construction Corps. We selected large-scale cattle and sheep farms, cooperatives, individual livestock households, livestock trading markets, slaughterhouses, and retail markets. Using cluster sampling, we recruited all livestock workers (1074 participants) at sampled sites. During the period from April to July 2024, we conducted face-to-face surveys with a self-designed questionnaire among livestock workers, collecting general demographic information, occupational exposure history, and information related to the use of personal protective equipment, resulting in 939 valid questionnaires. EpiData 3.1 was used for data entry and SPSS 26.0 for statistical analysis. We employed logistic regression to compare the implementation of personal protection among workers by selected categories. Results Among the study subjects, there were 300 workers from large-scale farms (31.95%) and 583 self-employed livestock farmers (62.09%). The sample included 600 males (63.90%) and 339 females (36.10%). The majority of the study subjects was farmers, breeders, or aged 18-60 years (87.75%), auxiliary workers (87.97%) and had an education level of junior high school or below (81.36%). The proportion of workers who consistently and correctly implemented all five personal protective measures (washing hands after work, wearing gloves, wearing masks, wearing dedicated work clothes, and using rubber boots) was 35.14% (330/939). The implementation rates for these five protective measures were 93.61% (879/939), 58.68% (551/939), 57.93% (544/939), 46.01% (432/939), and 42.81% (402/939), respectively. There were statistically significant differences in the implementation rates of differen personal protective measures among the workers by occupation and education level (P<0.05). Among them, workers with lower education levels had lower implementation rates for various protective measures. The results of logistic regression indicated that, compared to male workers, female workers (OR=2.26, 95%CI: 1.68, 3.04) showed a higher rate of non-standard implementation of personal protection. Using the age group of 18 to less than 36 years as a reference, those aged 36 to less than 60 years (OR=1.82, 95%CI: 1.33, 2.50) and 60 years or older (OR=4.45, 95%CI: 2.56, 7.73) reported higher rates of non-standard implementation of personal protection. Compared to those with an education level of primary school or below, those with a junior high school education (OR=0.64, 95%CI: 0.47, 0.88) and a high school education or above (OR=0.13, 95%CI: 0.19, 0.29) showed lower rates of non-standard implementation of personal protection. Compared to farmers, veterinarians (OR=0.03, 95%CI: 0.02, 0.07) reported the lowest rate of non-standard implementation of personal protection, followed by auxiliary workers (OR=0.08, 95%CI: 0.05, 0.12), breeders (OR=0.10, 95%CI: 0.07, 0.15), and other occupational groups (OR=0.28, 95%CI: 0.15, 0.52). Using large-scale farms as a reference, self-employed farmers (OR=13.5, 95%CI: 9.65, 18.88) reported a higher rate of non-standard implementation of personal protection, followed by workers from other workplaces (OR=3.63, 95%CI: 2.01, 6.54). Conclusion The implementation of personal protective measures among livestock workers in Xinjiang is generally satisfactory. However, significant disparities in the execution of these measures exist among different types of workers, indicating the need to enhance occupational health promotion to reduce the risk of zoonotic pathogen infection among the workers.

Background Animal farming may affect the structure and diversity of gut microbiota of farm workers, but it needs more studies to provide solid evidence. Objective To analyze the diversity characteristics of gut microbiota in dairy farm workers, dairy cows, and the control population (non-animal contact occupational group), and to assess the impact of dairy farming on the gut microbiota of workers. Methods The 16S rRNA full-length amplicon sequencing technology was used to sequence 60 fecal samples from dairy farm workers, 89 from dairy cows, and 50 from the general population. The gut microbiota structure characteristics, including operational taxonomic units (OTUs), alpha diversity, beta diversity, and the composition of species at the phylum, family, and genus levels were analyzed. The differences in gut microbiota among the three groups of samples were compared to explore the impact of occupational exposure on the gut microbiota structure of dairy farm workers. Results A total of 50478 OTUs were identified in the gut microbiota of farm workers, dairy cows, and the general population, with 23613, 42723, and 16592 OTUs, respectively. The number of shared OTUs between the dairy cows and the general population was 12674 (27.17%), between the general population and the farm workers was 10099 (33.54%), and between the dairy cows and the farm workers was 17690 (36.36%). Compared with the general population, the farm workers and dairy cows showed more shared gut microbiota (P<0.01). The abundance of Firmicutes in the gut of the farm workers was higher than that of the general population (P<0.01), while Actinobacteriota and Proteobacteria were the opposite (P<0.01). The alpha diversity of gut microbiota in the farm workers was different from that of the general population. The ACE index of the farm workers was slightly lower than that of the general population and much lower than that of dairy cows (P<0.05), while their Shannon index was higher than that of the general population but lower than that of dairy cows (P<0.01). The linear discriminant analysis effect size (LefSe) showed that the abundances of Lachnospiraceae and Ruminococcaceae in the gut microbiota of the farm workers were significantly higher than those of the general population, while Streptococcaceae, Lactobacillaceae, Bifidobacteriaceae, Enterobacteriaceae, and Erysipelatoclostridiaceae were lower than those of the general population. Conclusion The dairy farm workers shares a certain proportion of common bacterial communities with dairy cows. Dairy farming operations can affect the structure and diversity of the gut microbiota of workers by increasing the abundances of Lachnospiraceae and Ruminococcaceae, while decreasing the abundances of Streptococcaceae, Lactobacillaceae, Bifidobacteriaceae, Enterobacteriaceae, and Erysipelatoclostridiaceae. The study results provide reference data for further exploring the cross-host transmission of pathogens related to occupational exposure in dairy farming.

End stage heart failure(ESHF) is the terminal stage of heart failure in patients with heart failure, or refractory heart failure. heart transplantation(HT) and mechanical circulatory assistance represented by ventricular assist device(VAD) are the main treatments for circulatory support in patients with ESHF. However, the serious shortage of donors has restricted the extensive development of HT. VAD technology, represented by left ventricular assist device(LVAD), has developed rapidly, and the 2-year survival rate after surgery has approached of HT. Although LVAD support can directly alleviate symptoms of left heart failure, it only partially relieves symptoms of right heart failure, resulting in high readmission rates.Therefore, more precise monitoring and regulation of right heart function in LVAD recipients is key to improving long-term prognosis. This article aims to provide an overview of strategies for the regulation of right heart function in patients after LVAD implantation.

Objective To observe the value of diffusion weighted imaging intravoxel incoherent motion(IVIM)for quantitative evaluating chronic allograft dysfunction(CAD).Methods Totally 104 CAD patients were prospectively enrolled and were assigned into CAD 1,2 and 3 groups(n=11,61,32)based on impairment severity of estimated renal function,and 36 healthy volunteers were enrolled as control group.The true diffusion coefficient(D value),microcirculation perfusion diffusion coefficient(D*value)and perfusion score(f value)of renal cortex and medulla IVIM parameters were compared among groups and within groups to assess the value of IVIM parameters for diagnosing CAD.Results The D value of transplanted renal cortex in all CAD groups were lower than that in control group(all P＜0.05),which decreased among CAD 1,2 and 3 groups(all P＜0.05).The D value of transplanted kidney medulla in CAD 2 and 3 groups were lower than that in control group(both P＜0.05).The D*values of transplanted renal cortex in all CAD groups were lower than that in control group,while of renal medulla in CAD 2 and 3 groups were lower than that in control group(both P＜0.05).The f values of cortex and medulla in CAD 2 and 3 groups were lower than those in control group(all P＜0.05),while of cortex in CAD 3 group was lower than that in CAD 1 and 2 groups(both P＜0.05).The area under the curve(AUC)of cortical IVIM combined model for diagnosing CAD was 0.96,better than the D*value and f value(AUC=0.74,0.83,P＜0.05)but not significantly different with that of the D value(AUC=0.94,P=0.32).AUC of medullary IVIM combined model for diagnosing CAD was 0.91,better than that of D,D*and f value(AUC=0.80,0.67 and 0.80,all P＜0.05).Conclusion IVIM parameters could be used to quantitatively evaluate CAD.

Objective:To explore the clinicopathological and molecular genetic features of adult hepatic mesenchymal hamartoma (MHL).Methods:A total of five confirmed adult MHL cases diagnosed at the Pathology Department of the First Medical Center of the People's Liberation Army General Hospital between 2009 and 2022 were collected. Histomorphological observation and immunohistochemical staining were conducted. Gene detection was performed by next-generation sequencing.Results:Among the five cases, four were male and one was female, aged 46-67 years, with an average age of 56.2 years. The maximum diameter was 5.3-13.5cm, and the average diameter was 9.2cm. Tumors were generally cystic, solid, or mixed cystic-solid. Histopathologically, in four out of five cases of MHL, malignant transformation occurred, of which three cases were malignantly transformed into undifferentiated embryonal sarcoma and one case was malignantly transformed into a malignant solitary fibrous tumor. NAB2-STAT6 gene rearrangements were identified.Conclusion:Adult MHL is a rare kind of tumor with malignant potential, and it is difficult to diagnose with preoperative imaging examinations. A fine-needle biopsy is rarely used for diagnosis, but surgical resection of symptomatic or enlarged lesions is recommended to rule out the possibility of malignancy and further diagnosis. Genetic testing results revealed the complex genetic alterations in MHL, and it was found that adult MHL can malignantly transform into malignant solitary fibrous tumors. We believe that genome-wide analysis is necessary to determine the unique molecular characteristics of MHL and identify potential targets for therapeutic intervention.

Objective To evaluate the diagnostic efficacy of magnetic resonance defecography(MRD)in moderate or severe pelvic organ prolapse(POP)complicated with stress urinary incontinence(SUI).Methods Patients with grade Ⅱ or above POP were prospectively selected,and divided into POP combined with SUI group and isolated POP group.The MRD parameters of pelvic dysfunction between groups were analyzed to clarify the clinical diagnostic value and to evaluate the diagnostic efficacy of MRD in POP combined with SUI.Results This study enrolled 99 POP patients,42 patients in isolated POP group,and 57 patients in POP combined with SUI group.The comparison between groups showed there were significant differences in the function of the urethra and bladder,including the position of the urethro-vesical junction(1.61 cm±1.03 cm vs 2.13 cm±0.71 cm),the position of the posterior bladder wall(4.13 cm±2.46 cm vs 5.23 cm±2.21 cm),the urethra angle(94.22°±35.62°vs 114.28°±35.55°),the length of the closed urethra(2.28 cm±0.90 cm vs 2.15 cm±0.65 cm),and bladder funneling(23.81％vs 45.61％),all the differences were statistically significant(P＜0.05).The area under the curve(AUC)of multiple parameters MRD in the diagnosis of SUI was 0.73.The AUC in diagnosis of SUI by MRD combined with clinical history was 0.95.Conclusion POP combined with SUI has characteristic MRD signs.MRD technology can assist clinicians and improve the preoperative diagnosis rate of moderate and severe POP combined with SUI.

A comprehensive understanding of the nutritional composition and active components of human milk are important for promoting infant health. However, in the design and implementation of scientific research on human milk, the lack of standardized research and implementation methods have led to the collection, storage, and testing processes of human milk samples being largely based on reference literature and practical experience. This has resulted in variability in the representativeness of human milk samples and differences in the comparability of research results between different studies. This article summarizes the principles and guidelines for the " Specification for collection and storage of human milk samples for research", published by the Chinese Nutrition Society on December 30, 2022, and discusses the feasibility and importance of standardized management in the process of scientific research on human milk.

OBJECTIVE: To explore the mechanisms that mediate the anti-inflammatory activity of Eurycoma longifolia. METHODS: Kunming mouse models of xylene-induced ear swelling and lipopolysaccharide (LPS)-induced acute pneumonia were used to compare the anti- inflammatory activities of aqueous and ethanol extracts of Eurycoma longifolia. UPLC-Q-TOF-MS/MS was used to identify the chemical composition in the ethanol extract of Eurycoma longifolia, based on which the potential antiinflammatory targets of Eurycoma longifolia were screened using the databases including SwissADME, SwissTargetPrediction, and Genecards. The String database was used to generate the protein-protein interaction (PPI) network, and Cytoscape was used for network topology analysis and screening the core targets. The enrichment of the core targets was analyzed using Metascape database, the core components and targets were docked with Autodock software, and the docking results were visualized using Pymol software. In a RAW264.7 cell model of LPS-induced inflammation, the Griess reagent was used to measure NO level, and Western blotting was performed to detect the expression levels of MAPK1, JAK2, and STAT3 proteins to verify the anti- inflammatory mechanism of Eurycoma longifolia. RESULTS: The ethanol extract (75%) of Eurycoma longifolia (ELE) was the active site, which contained a total of 37 chemical components. These chemical compounds and diseases had 541 targets, involving the JAK/STAT3, cAMP and other signaling pathways. Twelve indicator components were identified, which all showed good results of molecular docking with two core targets involved in the signaling pathways. In the cell validation experiment, treatment of the cells with low-, medium-, and high-dose ELE significantly reduced NO release in the cells, and ELE at the medium dose significantly decreased the cellular expressions of JAK2 and STAT3. CONCLUSION The anti-inflammatory activity of Eurycoma longifolia is attributed primarily to its active ingredients bitter lignin and alkaloids, which may regulate the JAK/STAT3 signaling pathway by targeting JAK2 and STAT3.
