ObjectiveTo investigate the role of Ras-GTPase-activating protein SH3 domain-binding protein 2 （G3BP2） in regulating the activation， proliferation， and migration of hepatic stellate cells （HSCs）. MethodsThe mouse HSCs （JS-1 cell line） were treated with 5 μg/L transforming growth factor-beta 1（TGF-β1） for 24 hours to establish an HSC activation and proliferation model. A G3BP2 knockdown system was constructed using siRNA interference technology. The experiment was divided into four groups： Control， TGF-β1 treatment， TGF-β1+si-NC， and TGF-β1+ G3BP2-siRNA. The expression levels of key fibrosis indicators， including type I collagen （Collagen I）， α-smooth muscle actin （α-SMA）， and G3BP2， were detected by Western blot and RT-qPCR. Cell proliferation activity was assessed using the CCK-8 proliferation assay kit and EdU fluorescence labeling technology. Cell migration ability was analyzed by scratch wound healing assay and Transwell migration assay. The formation level of stress granules was quantified by immunofluorescence microscopy to investigate the effects of G3BP2 on stress granule formation in activated HSCs. ResultsStimulation with TGF-β1 upregulated the expression of G3BP2 in JS-1 cells （RT-qPCR： P0.000 1； Western blot： P0.000 1）， while a downward trend in its expression was observed in the G3BP2‑silenced group （RT-qPCR： P0.01； Western blot： P0.000 1）. Compared with the control group， the TGF-β1 group exhibited increased protein expression levels of α-SMA and Collagen I （RT-qPCR： both P0.01； Western blot： P0.01 and P0.05， respectively）， concomitant with an increased number of stress granules and enhanced cell proliferation and migration capacity （all P0.001）. The experimental results demonstrated that G3BP2 knockout effectively reversed the aforementioned phenotypes， with the G3BP2-silenced group showing reduced expression of fibrotic markers （all P0.01）， decreased stress granule formation （P0.01）， and reduced cell proliferation and migration capacity （all P0.05）， compared to the negative control group. ConclusionG3BP2 enhances the activation， proliferation， and migration of HSCs by promoting the formation of stress granules， thereby accelerating the pathological progression of liver fibrosis. This suggests that stress granules may serve as important regulators in controlling the activation， proliferation， and migration of HSCs.

ObjectiveTo investigate the correlation between neutrophil-to-lymphocyte ratio （NLR）， platelet-to-lymphocyte ratio （PLR）， systemic immune-inflammation index （SII） and the severity of intrauterine adhesions （IUA）. MethodsThe retrospective study included 380 patients who underwent transcervical resection of adhesions （TCRA） from December 2019 to March 2025. Based on the American Fertility Society （AFS） classification， patients were divided into mild （n=61）， moderate （n=225）， and severe （n=94） groups. NLR， PLR， and SII were calculated from preoperative blood tests. Statistical analyses included Kruskal-Wallis test and ordinal Logistic regression. ResultsNLR， PLR， and SII were significantly higher in the severe IUA group compared to the mild group （P<0.05）， with SII showing the strongest predictive ability （OR=1.004， P=0.001）. The number of intrauterine procedures was an independent risk factor （OR=1.27/level， P=0.016）. The predictive model ［Logit（P）=-0.676+0.241×operation times+0.004×SII］ effectively identified severe IUA cases. ConclusionInflammatory markers （particularly SII） are correlated with IUA severity and may serve as non-invasive tools for clinical assessment.

Background Work-related musculoskeletal disorders (WMSDs) are common across industries. Workers in the hairdressing industry are frequently exposed to repetitive upper-limb movements and awkward working postures, which may increase their susceptibility to WMSDs. However, evidence on WMSDs among workers in this industry remains limited. Objective This study aimed to investigate the prevalence of self-reported WMSDs symptoms and associated factors among workers in the hairdressing industry in Hongkou District, Shanghai. Methods A cross-sectional survey was conducted using quota sampling in all eight subdistricts of Hongkou District, Shanghai. Hair salons in each subdistrict were ranked by the number of hairdressers and shampoo workers, and the 6 salons with the largest staff size in each subdistrict were selected, resulting in 48 survey sites. Hairdressers and shampoo workers who met the inclusion and exclusion criteria were surveyed using the Chinese version of the Musculoskeletal Disorders Questionnaire. Information on their individual characteristics, musculoskeletal symptoms, and work-related factors was collected. Chi-square tests and Firth logistic regression were used to estimate the prevalence of self-reported WMSDs symptoms and identify associated factors. Results The overall prevalence of self-reported WMSDs symptoms among workers in the hairdressing industry was 45.72%. Among hairdressers, the most commonly affected body regions were the neck (31.51%), shoulders (25.57%), lower back (15.98%), and feet (14.61%). Among shampoo workers, the most commonly affected regions were the neck (24.17%), lower back (24.17%), shoulders (20.83%), and upper back (10.83%). Firth logistic regression showed that fatigue in the corresponding body region after several hours of continuous work was positively associated with self-reported WMSDs symptoms in both types of workers (OR=6.544-52.838). Regarding individual characteristics, shorter height (female≤160 cm, male≤165 cm) was positively associated with self-reported neck and foot symptoms among hairdressers, and self-reported shoulder symptoms among shampoo workers (OR=16.324, 15.084, 9.680). Female shampoo workers had higher odds of self-reported neck symptoms than male shampoo workers (OR=4.924). Smoking was positively associated with self-reported upper-back and lower-back symptoms among shampoo workers (OR=10.544, 4.381). Among work-related factors, maintaining a fixed neck posture for long periods among hairdressers and prolonged standing among shampoo workers were positively associated with self-reported neck symptoms (OR=6.123, 3.080). Among shampoo workers, frequent overtime and maintaining a twisted posture were positively associated with self-reported upper-back symptoms (OR=11.710, 35.306). Sufficient rest time was negatively associated with self-reported foot symptoms among hairdressers (OR=0.238). Conclusion The prevalence of self-reported WMSDs symptoms was relatively high among workers in the hairdressing industry. Work-related fatigue and awkward working postures were strongly associated with WMSDs symptoms. Measures such as optimizing work-rest schedule, improving ergonomic workplace design, implementing fatigue monitoring and management, promoting work-break exercises, and providing training on appropriate working posture may help reduce the burden of WMSDs symptoms in this occupational group.

ObjectiveTo investigate the synergistic promotion of malignant phenotypes in gastric cancer cells by tumor-associated bone marrow mesenchymal stem cells （TA-BMSCs） and polymorphonuclear myeloid-derived suppressor cells （PMN-MDSCs） through crosstalk， and the intervention mechanism of the intestinal absorption solution containing Banxia Xiexintang （BXT）. MethodsGastric cancer MFC cells were treated with conditioned medium （co-culture-CM） prepared from a co-culture system of TA-BMSCs and PMN-MDSCs. Groups included control， co-culture-CM model， stromal cell-derived factor 1 （SDF1） inhibitor （LY2510924）， α₄β₁ inhibitor （BIO5192）， dual inhibitor combination， and different concentrations （55%， 70%， 85%） of BXT-containing intestinal absorption solutions. MFC cell proliferation， migration， invasion， and apoptosis were assessed via cell counting kit-8 （CCK-8） assay， wound-healing assay， Transwell assay， and flow cytometry. The SDF-1， α₄β₁， matrix metalloproteinase-9 （MMP-9）， and vascular endothelial growth factor A （VEGFA） levels in culture supernatants， along with the protein levels of intracellular macrophage migration inhibitory factor （MIF）， chemokine （C-X-C motif） receptor 4 （CXCR4）， CD106， MMP-9， and VEGFA in MFC cells， were measured by enzyme-linked immunosorbent assay （ELISA） and Western blot， respectively. ResultsCompared with the control group， co-culture-CM promoted the proliferation， migration， and invasion of MFC cells （P<0.01）， elevated the levels of SDF-1， α₄β₁， MMP-9， and VEGFA （P<0.01）， and upregulated the protein levels of MIF （P<0.05）， MMP-9 （P<0.01）， and VEGFA （P<0.01）. Compared with co-culture-CM， BXT-containing intestinal absorption solutions at various concentrations significantly reversed the phenotypic effects on cells， inhibited malignant phenotypes， lowered the levels of MMP-9 and SDF1， and reduced the expression of proteins in the crosstalk axis. Compared with the SDF1+α₄β₁ inhibitor group， the SDF1 inhibitor group and the α₄β₁ inhibitor group showed no differences in the inhibition of proliferation， scratch healing， and cytokine levels. The SDF1 inhibitor increased the apoptosis rate and downregulated the protein levels of MIF and CD106， while the α₄β₁ inhibitor increased the number of migrated cells and the expression of various proteins. Compared with the SDF1 inhibitor group， the α₄β₁ inhibitor group showed reduced inhibitory effect on proliferation， decreased apoptosis rate， increased number of invasive cells， decreased α₄β₁ content， and increased expression of various proteins （P<0.01）. The 55%， 70%， and 85% intestinal absorption solutions increased the inhibitory effect on proliferation， decreased the number of invasive cells， and increased the apoptosis rate （P<0.01）. The 55% BXT-containing intestinal absorption solution group showed increased wound healing rate and upregulated protein levels of VEGFA， CD106， and MMP-9 （P<0.05）. The 70% intestinal absorption solution group showed upregulated protein level of MIF （P<0.05）， and the 85% intestinal absorption solution group showed upregulated protein level of VEGFA （P<0.01） and downregulated the protein level of CXCR4 （P<0.01）. ConclusionTA-BMSCs and PMN-MDSCs synergistically activate the MIF/SDF-1/CXCR4 and MMP-9/α₄β₁/CD106 axes through crosstalk， significantly enhancing gastric cancer cell invasion and migration. BXT-containing intestinal absorption fluid effectively inhibits the malignant progression of gastric cancer cells by multi-targeted intervention in this crosstalk process.

ObjectiveTo explore whether the intestinal absorption solution containing Banxia Xiexintang （BXT） can inhibit the invasion and migration of gastric cancer cells by interfering with the stromal cell-derived factor 1 （SDF1）-CXC chemokine receptor 4 （CXCR4） axis in tumor-associated bone marrow mesenchymal stem cells （TA-BMSCs）. MethodsThe intestinal absorption solution containing BXT was prepared， and the optimal intervention concentration and duration for MFC cells were determined through the cell counting kit-8 （CCK-8） assay. A co-culture system was established comprising TA-BMSCs conditioned medium （TA-BMSCs-CM） and gastric cancer MFC cells. The experiment was conducted with a blank control group， a TA-BMSCs-CM group， an SDF1 inhibitor （LY2510924） group， and intervention groups with varying concentrations （55%， 70%， 85%） of the intestinal absorption solution containing BXT. Cell proliferation was assessed by the CCK-8 assay. Horizontal and vertical cell migration were evaluated via scratch and Transwell assays， respectively. Cell invasion was examined by a Transwell assay with Matrigel. Cell apoptosis was detected by flow cytometry. The levels of factors such as SDF1， matrix metalloproteinase-9 （MMP-9）， and vascular endothelial growth factor A （VEGFA）， as well as the protein levels of macrophage migration inhibitory factor （MIF）， CXCR4， VEGFA， and MMP-9， were quantified by ELISA and Western blot， respectively. ResultsThe CCK-8 assay results indicated that compared with the 24 h intervention， the 48 h interventions with all concentrations of the intestinal absorption solution containing BXT increased the inhibition rate on MFC cells （P<0.01）. The half-maximal inhibitory concentration （IC₅₀） of the intestinal absorption solution containing BXT at the time point of 48 h was 68.51%， and subsequent intervention concentrations were selected as 55%， 70%， and 85%. Compared with the TA-BMSCs-CM group， the intestinal absorption solution containing BXT （particularly at concentrations of 70% 85%） suppressed the proliferation， migration， and invasion of MFC cells， promoted the cell apoptosis （P<0.05， P<0.01）， decreased the levels of SDF1， MMP-9， and VEGFA， and downregulated the protein levels of MIF， CXCR4， VEGFA， and MMP-9 （P<0.05， P<0.01）. The inhibitory effects of the intestinal absorption solution containing BXT were comparable to or superior to those of the SDF1 inhibitor （P<0.01）. ConclusionThe intestinal absorption solution containing BXT can inhibit the invasion and migration of gastric cancer cells by interfering with the SDF1-CXCR4 axis in TA-BMSCs. The underlying mechanism may involve the regulation of the MIF/SDF1/CXCR4 signaling pathway and its downstream effector molecules.

Immunoglobulin G4-related disease (IgG4-RD) is a rare systemic immune-mediated disorder characterized by infiltration of IgG4-positive plasma cells and multiorgan fibrosis. Among them, cases with multiple pancreatic cystic lesions as the prominent manifestation are relatively rare, and they are easily misdiagnosed as pancreatic tumors or pancreatitis in clinical practice. Herein, we report one patient with IgG4-RD admitted to Peking Union Medical College Hospital. The patient initially presented with multiple pancreatic cystic lesions and aneurysmal dilatation of the abdominal aorta, accompanied by markedly elevated serum IgG4 levels. Combined with pathological findings from submandibular gland biopsy, the diagnosis of IgG4-RD was ultimately established. After treatment with a regimen of glucocorticoids combined with cyclophosphamide, the patient′s condition improved. Meanwhile, we performed a literature review of cases with IgG4-RD-related pancreatic cystic lesions, aiming to improve clinicians′ understanding of this rare disease phenotype.

Objective To explore the value of spectral CT multi-parameter imaging for diagnosing bronchial anthracofibrosis(BAF)complicated with active pulmonary tuberculosis.Methods Totally 77 patients with BAF complicated with atelectasis were retrospectively enrolled.According to undergoing anti-tuberculosis treatment or not during hospitalization,26 patients complicated with active pulmonarg tuberculosis were divided into group A(n=26),while 51 cases without active pulmonarg tuberculosis were divided into group B.Signs indicating active pulmonary tuberculosis(i.e.tree-in-bud sign or centrilobular nodules)on chest spectral CT images were analyzed.Non-enhanced CT(NECT)values,single-energy CT values at 40 keV(CT40 kev)and 70 keV(CT70 kev),as well as effective atomic number(Zeff),iodine concentration(IC),calcium concentration(CC)and hydroxyapatite concentration(HAP)in the arterial phase and venous phase of enhancement at the site of bronchial obstruction and in subcarinal lymph nodes were measured.the slope of spectral line(λ40-70keV)was calculated and compared between groups.Receiver operating characteristic(ROC)curve was plotted,and the area under the curve(AUC)was used to evaluate the efficacy of the above parameter alone and their combinations for diagnosing BAF complicated with active pulmonarg tuberculosis.Results The displaying rate of active pulmonary tuberculosis CT signs in group A was higher than that in group B(P=0.005).NECT values,enhanced venous phase CT40kev,λ40-70 kev,as well as Zeff,IC,CC and HAP at the site of bronchial obstruction in group A were all lower than those in group B(all P＜0.05).The AUC of active pulmonary tuberculosis CT signs for assessing BAF complicated with active pulmonary tuberculosis was 0.659,of the combination of CT quantitative parameters at the site of bronchial obstruction was 0.769,while of the combination of CT signs and CT quantitative parameters was 0.825,higher than of active pulmonary tuberculosis CT signs alone(P＜0.05).Conclusion Spectral CT multi-parameter imaging could be used to effectively diagnose BAF complicated with active pulmonary tuberculosis.

Malignant tumors(commonly referred to as cancer)represent a major global public health challenge and contribute significantly to the worldwide disease burden.Early screening plays a critical role in improving detection rates,enabling timely intervention,and enhancing pa-tient survival rates.However,current cancer screening guidelines primarily focus on site-specific screening,which may not fully address the need for comprehensive early detection.A scientifical-ly rational,multi-cancer screening approach offers several advantages:it optimizes the use of bio-logical samples,reduces time costs for participants,enhances the efficiency and comprehensive-ness of screening,and minimizes overall expenses.Such an approach also facilitates the rational allocation of healthcare resources,ultimately helping to reduce the societal burden of cancer.To address this need,the Cancer Epidemiology Committee of the Chinese Anti-Cancer Association has developed the Expert Consensus on Combined Screening for Common Cancers in China.This consensus integrates multidisciplinary expertise and synthesizes the latest domestic and interna-tional researches on cancer screening,early detection,and treatment for prevalent malignancies.Drawing upon China's unique demographic and healthcare context,as well as practical screening experiences,the consensus provides evidence-based recommendations on target populations,screening technologies,and procedural workflows for multi-cancer screening.These guidelines align with the principles and methodologies established by the World Health Organization(WHO),aiming to:enhance the effectiveness of combined cancer screening in China,improve early detec-tion rates,and provide a scientific foundation for national cancer prevention and control strategies.
