ObjectiveTo investigate the possible mechanism of Jishe Qushi Capsule (脊蛇祛湿胶囊, JQC) in treating rheumatoid arthritis (RA) from the perspective of macrophage polarization mediated by neutrophil extracellular traps (NETs). MethodsTwenty-four female SD rats were randomly divided into four groups, blank control group, model group, JQC group, and peptidylarginine deiminase 4 (PAD4) inhibitor group with 6 rats in each group. All groups but the blank control group were subjected to the induction of collagen-induced arthritis (CIA). After successful model establishment, rats in the JQC group received intragastric administration of JQC 1.47 g/kg daily; rats in the PAD4 inhibitor group received intraperitoneal injections of the PAD4 inhibitor 4 mg/kg weekly. Rats in the blank, model, and PAD4 inhibitor groups received 2 ml of pure water daily by gavage. All treatments lasted 4 weeks. Joint lesions of each group were assessed on day 7, 14, 21, 28, and 35 after model establishment, and arthritis index (AI) scores were recorded. At 24 h after the final administration, histopathology of knee joints, including HE staining, safranin O-fast green staining, and TRAP staining, was performed. Flow cytometry was used to detect the counts of M1 and M2 macrophages in peripheral blood. ELISA was used to determine serum levels of TRACP, NETs, TNF-α, IL-1β, and iNOS. Western Blotting and qRT-PCR were used to measure MPO, NE, RANKL, OPG, and p65 protein and mRNA expression in knee cartilage tissue. ResultsCompared with the blank control group, the model group showed increased AI scores (P<0.05), marked synovial inflammatory infiltration, angiogenesis, and bone-cartilage destruction, increased TRAP-positive osteoclasts, increased M1 macrophages and decreased M2 macrophages, elevated serum TRACP, NETs, TNF-α, IL-1β, and iNOS (P<0.05), elevated MPO, NE, RANKL, and p65 protein/mRNA expression and decreased OPG protein/mRNA expression in knee cartilage tissue (P<0.05). Compared with the model group, the JQC group exhibited improved synovial inflammation, angiogenesis, and bone-cartilage damage, reduced AI scores on day 21, 28, and 35, decreased osteoclast counts, decreased M1 macrophages and increased M2 macrophages, reduced serum TRACP, NETs, TNF-α, IL-1β, and iNOS (P<0.05), decreased MPO, NE, RANKL, and p65 protein/mRNA expression and increased OPG expression (P<0.05). Compared with the PAD4 inhibitor group, the JQC group showed significantly lower AI scores, reduced M1 macrophages, increased M2 macrophages (P<0.05), reduced serum TRACP, TNF-α, IL-1β, and iNOS, decreased MPO, RANKL, and p65 expression, and increased OPG levels (P<0.05). ConclusionThe therapeutic mechanism of JQC for RA may involve inhibition of NETs formation, downregulation of the RANKL/NF-κB signaling pathway, and regulation of macrophage M1/M2 polarization imbalance, thereby suppressing osteoclastogenesis and inflammatory bone destruction.

ObjectiveTo observe the effects of Yangjing Zhongyutang (YJZYT) on mitochondrial biogenesis and oxidative stress damage mediated by the silent information regulator 1 (SIRT1)/peroxisome proliferator-activated receptor gamma coactivator-1alpha (PGC-1α) signaling pathway in cyclophosphamide (CTX)-induced rats with diminished ovarian reserve (DOR), and to explore its mechanism in improving ovarian reserve function and follicular development. MethodsForty-two 8-week-old female SD rats with normal estrous cycles were randomly divided into a blank control group (n=7) and a model group (n=35). Rats in the model group received a single intraperitoneal injection of CTX (90 mg·kg-1) to establish the DOR model. After modeling, estrous cycles were monitored for 7 consecutive days, and model success was confirmed based on criteria for estrous cycle disruption. After successful modeling, rats were divided into groups for intervention: estradiol valerate group (0.09 mg·kg-1), and YJZYT high-, medium-, and low-dose groups (19.98, 9.99, 5.00 g·kg-1). The blank control group and model group were given an equal volume of distilled water by gavage. All groups received daily gavage once for 4 consecutive weeks. The general state, body weight, and ovarian wet weight of rats were observed and recorded, and the ovarian organ index was calculated. Enzyme-linked immunosorbent assay (ELISA) was used to measure serum levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), anti-Müllerian hormone (AMH), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px). Hematoxylin-eosin (HE) staining was performed to observe ovarian histomorphological changes and follicular development status. Immunofluorescence was used to detect reactive oxygen species (ROS) expression levels. Colorimetric assays were employed to measure adenosine triphosphate (ATP) and malondialdehyde (MDA) content in ovarian tissues. Quantitative Real-time polymerase chain reaction (Real-time PCR) was used to detect mitochondrial DNA (mtDNA) copy number and the mRNA expression levels of key genes including SIRT1, PGC-1α, nuclear respiratory factor 1 (NRF1), and mitochondrial transcription factor A (TFAM). Western blot was performed to detect the protein expression levels of SIRT1, PGC-1α, NRF1, and TFAM. ResultsCompared with the blank group, rats in the model group exhibited disrupted estrous cycles, obviously reduced body weight, and decreased ovarian index (P<0.05). Ovarian histopathology revealed cortical thinning, loose structure, and a significant reduction in both primordial and growing follicles (P<0.01). Serum FSH and LH levels were significantly elevated (P<0.01), while E2 and AMH levels were obviously reduced (P<0.05, P<0.01). ATP content and mtDNA copy number decreased in ovarian tissue (P<0.01), ROS expression increased, MDA levels rose, while SOD and GSH-Px activities obviously decreased (P<0.05, P<0.01), mRNA and protein expression levels of SIRT1, PGC-1α, NRF1, and TFAM were obviously downregulated (P<0.05, P<0.01). After treatment, compared with the model group, body weight and ovarian index obviously recovered in rats administered various doses of YJZYT (P<0.05), serum E2 and AMH levels increased, while FSH and LH levels obviously decreased (P<0.05, P<0.01), ovarian tissue ATP content and mtDNA copy number were up-regulated, ROS and MDA levels decreased, and antioxidant enzymes SOD and GSH-Px activity obviously increased (P<0.05, P<0.01), Gene and protein expression levels related to the SIRT1/PGC-1α /NRF1/TFAM signaling pathway were obviously up-regulated compared to the model group (P<0.05, P<0.01), HE staining revealed that ovarian structure gradually recovered to integrity in all treatment groups, with a obviously increase in the number of primordial and growing follicles (P<0.05, P<0.01). Granulosa cells were neatly arranged, indicating marked improvement in ovarian function. ConclusionYJZYT may improve ovarian function and follicular development in rats with diminished ovarian reserve by activating the SIRT1/PGC-1α signaling pathway, promoting mitochondrial biogenesis, enhancing mitochondrial function, and alleviating oxidative stress damage.

ObjectiveTo analyze the epidemiological characteristics and clinical symptoms of severe fever with thrombocytopenia syndrome (SFTS) cases in Xianju County, Zhejiang Province from 2017 to 2024, and to provide a scientific basis for prevention and control measures to reduce the incidence and mortality. MethodsSFTS cases reported in Xianju County from 2017 to 2024 were collected from the China Information System for Disease Prevention and Control. Case-related data were obtained through epidemiological investigations and medical record reviews. Data were organized and analyzed using WPS 2019 and SPSS 22.0, spatial maps were generated with ArcGIS 10.2, and multivariate logistic regression analyses were employed to explore the factors associated with mortality in SFTS cases. ResultsFrom 2017 to 2024, a total of 36 SFTS cases were reported in Xianju County, with an incidence rate of 1.15/100 000 and a case fatality rate of 27.78% (10/36). The majority of cases occurred in individuals aged 60 years old and above (55.56%, 20/36), with farmers being the most affected occupational group (86.11%, 31/36). The highest number of reported cases occurred in June and July. The local tick density was relatively high (1.25 ticks per host, 340/271). Multivariate logistic regression analyses indicated that thrombocytopenia was a related factor for patient mortality. ConclusionXianju County is an area with high incidence and case fatality rate of SFTS. It is essential to strengthen public awareness campaigns, emphasizing personal protection during outdoor activities to reduce infections and lower the incidence rate. In addition, comprehensive control measures such as environmental cleanup and pesticide application should be taken to reduce tick density. Local medical institutions should enhance professional training to improve diagnostic and report sensitivity for SFTS. Early symptomatic treatment should be prioritized for elderly patients and severe thrombocytopenia cases to reduce the case fatality rate.

Background Silicosis, caused by inhalation of silica (SiO2) dust, remains the most prevalent occupational pneumoconiosis in China. While galectin-3 (Gal-3) is known to play pro-inflammatory and pro-fibrotic roles in various diseases, its specific mechanism in the pathogenesis of silicosis has not been fully clarified. Objective To investigate the role and underlying mechanisms of Gal-3 in silicosis using clinical samples of silicosis and a silicosis mouse model. Methods Lung nodule biopsy samples were collected from patients with stage III pneumoconiosis. Concurrently a silicosis mouse model was constructed via non-exposed tracheal intubation with instillation of a SiO2 suspension. The expression levels of Gal-3 mRNA and protein in the lung tissues of the silicosis model mice were then detected using real-time quantitative polymerase chain reaction (RT-qPCR) and immunohistochemistry (IHC) staining. Single-cell transcriptomic sequencing (scRNA-seq) was performed on both human and murine lung samples to analyze the expression of the Gal-3-encoding gene Lgals3 across different cell types. In vitro, RAW264.7 macrophages were treated with varying concentrations of SiO2 suspension for 24 h and 48 h; the expression levels of Gal-3 mRNA and protein were measured by RT-qPCR and Western blot. The Gal-3 inhibitor TD139 was used to intervene in the SiO2-induced in vitro macrophage model, and Western blot was used to detect the intracellular expression of interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), and transforming growth factor-β1 (TGF-β1). Finally, mouse embryonic lung fibroblasts NIH/3T3 and Mlg2908 were treated with varying concentrations of recombinant mouse Gal-3 protein (rmGal-3) for 48 h, and Western blot was used to detect the expression of fibrosis markers [(Collagen I, Collagen III, Fibronectin, and α smooth muscle actin (α-SMA)] and proteins associated with the TGF-β1/Smads signaling pathway. Results RT-qPCR and IHC staining showed that both the gene and protein expression levels of Gal-3 were significantly elevated at all consecutive time points in the silicosis mouse model (P < 0.05). scRNA-seq revealed that Lgals3 was aberrantly highly expressed in lung tissues from pneumoconiosis patients and silicosis mouse models, with the highest expression observed in macrophages. After treatment of macrophages with different concentrations of SiO2 for 24 h and 48 h, the mRNA and protein expression levels of Gal-3 were significantly upregulated compared with the control group (P < 0.05). Following TD139 intervention, the protein expression levels of IL-1β, TNF-α, and TGF-β1 in dust-exposed macrophages were markedly downregulated (P < 0.0001). After 48 h of stimulation with rmGal-3, the protein expression levels of Collagen I, Fibronectin, and α-SMA in mouse embryonic lung fibroblasts (NIH/3T3 and Mlg2908) were significantly increased in all treatment groups compared with the control group (P < 0.01). Moreover, Gal-3 treatment markedly upregulated TGF-β1 protein expression in Mlg2908 cells and enhanced the phosphorylation levels of Smad2 and Smad3 (P < 0.0001). Conclusion Gal-3 is abnormally expressed in silicotic lung tissues, which primarily originates from macrophages, and inhibition of Gal-3 suppresses SiO2-induced inflammatory and pro-fibrotic responses. In addition, Gal-3 promotes fibroblast differentiation and extracellular matrix production by activating the TGF-β1/Smads signaling pathway.

Critically ill patients often experience significant skeletal muscle wasting due to prolonged bed rest, metabolic disorders, inflammatory responses and malnutrition, which affects the patient's mobility and may also lead to increased mortality. Timely and accurate assessment of muscle status is important for optimizing treatment strategies and improving patient prognosis. There are various limitations in the current methods of assessing muscle mass, and muscle ultrasound, as a noninvasive, convenient, low-cost and suitable technique for bedside monitoring, has received increasing attention for its application in muscle assessment of critically ill patients. However, there are still a number of challenges in its practical application, such as the lack of uniform standards for the measurement method, the high dependence on the operation, and the reproducibility of the data that needs to be optimized, and so on. The aim of this article is to systematize the research progress of muscle ultrasound in muscle assessment of critically ill patients, and to discuss the advantages and limitations of its clinical application, in order to provide a scientific basis for future research and clinical practice.

Journal of Integrative Medicine 2025;23(6):630-640
BACKGROUND:
The use of inserted sham acupuncture as a placebo in randomized controlled trials (RCTs) is controversial, because it may produce specific effects that cause an underestimation of the effect of acupuncture treatment.
OBJECTIVE:
This systematic survey investigates the magnitude of insert-specific effects of sham acupuncture and whether they affect the estimation of acupuncture treatment effects.
SEARCH STRATEGY:
PubMed, Embase and Cochrane Central Register of Controlled Trials were searched to identify acupuncture RCTs from their inception until December 2022.
INCLUSION CRITERIA:
RCTs that evaluated the effects of acupuncture compared to sham acupuncture and no treatment.
DATA EXTRACTION AND ANALYSIS:
The total effect measured for an acupuncture treatment group in RCTs were divided into three components, including the natural history and/or regression to the mean effect (controlled for no-treatment group), the placebo effect, and the specific effect of acupuncture. The first two constituted the contextual effect of acupuncture, which is mimicked by a sham acupuncture treatment group. The proportion of acupuncture total effect size was considered to be 1. The proportion of natural history and/or regression to the mean effect (PNE) and proportional contextual effect (PCE) of included RCTs were pooled using meta-analyses with a random-effect model. The proportion of acupuncture placebo effect was the difference between PCE and PNE in RCTs with non-inserted sham acupuncture. The proportion of insert-specific effect of sham acupuncture (PIES) was obtained by subtracting the proportion of acupuncture placebo effect and PNE from PCE in RCTs with inserted sham acupuncture. The impact of PIES on the estimation of acupuncture's treatment effect was evaluated by quantifying the percentage of RCTs that the effect of outcome changed from no statistical difference to statistical difference after removing PIES in the included studies, and the impact of PIES was externally validated in other acupuncture RCTs with an inserted sham acupuncture group that were not used to calculate PIES.
RESULTS:
This analysis included 32 studies with 5492 patients. The overall PNE was 0.335 (95% confidence interval [CI], 0.255-0.415) and the PCE of acupuncture was 0.639 (95% CI, 0.567-0.710) of acupuncture's total effect. The proportional contribution of the placebo effect to acupuncture's total effect was 0.191, and the PIES was 0.189. When we modeled the exclusion of the insert-specific effect of sham acupuncture, the acupuncture treatment effect changed from no difference to a significant difference in 45.45% of the included RCTs, and in 40.91% of the external validated RCTs.
CONCLUSION
The insert-specific effect of sham acupuncture in RCTs represents 18.90% of acupuncture's total effect and significantly affects the evaluation of the acupuncture treatment effect. More than 40% of RCTs that used inserted sham acupuncture would draw different conclusions if the PIES had been controlled for. Considering the impact of the insert-specific effect of sham acupuncture, caution should be taken when using inserted sham acupuncture placebos in RCTs.

OBJECTIVE:
Hepatocellular carcinoma (HCC) is sensitive to ferroptosis, a new form of programmed cell death that occurs in most tumor types. However, the mechanism through which ferroptosis modulates HCC remains unclear. This study aimed to investigate the oncogenic role and prognostic value of FANCD2 and provide novel insights into the prognostic assessment and prediction of immunotherapy.
METHODS:
Using clinicopathological parameters and bioinformatic techniques, we comprehensively examined the expression of FANCD2 macroscopically and microcosmically. We conducted univariate and multivariate Cox regression analyses to identify the prognostic value of FANCD2 in HCC and elucidated the detailed molecular mechanisms underlying the involvement of FANCD2 in oncogenesis by promoting iron-related death.
RESULTS:
FANCD2 was significantly upregulated in digestive system cancers with abundant immune infiltration. As an independent risk factor for HCC, a high FANCD2 expression level was associated with poor clinical outcomes and response to immune checkpoint blockade. Gene set enrichment analysis revealed that FANCD2 was mainly involved in the cell cycle and CYP450 metabolism.
CONCLUSION
To the best of our knowledge, this is the first study to comprehensively elucidate the oncogenic role of FANCD2. FANCD2 has a tumor-promoting aspect in the digestive system and acts as an independent risk factor in HCC; hence, it has recognized value for predicting tumor aggressiveness and prognosis and may be a potential biomarker for poor responsiveness to immunotherapy.
