Background Arsenic is an environmentally harmful substance that causes hepatic insulin resistance and liver damage, increasing the risk of type 2 diabetes mellitus. Objective To explore whether the insulin-like growth factor 2 mRNA binding protein 2 (IGF2BP2) is involved in insulin resistance in HepG2 cells after arsenic exposure through the peroxisome-proliferator-activated receptor γ (PPAR-γ) / glucose transporter 4 (GLUT4) pathway. Methods Cell viability was determined using cell counting kit 8 (CCK8) and an appropriate NaAsO₂ infection dose was determined. A cellular arsenic exposure model of HepG2 cells was established by four concentrations of NaAsO₂ solution for 24 h (the experiment was divided into four groups: 0, 2, 4, and 8 μmol·L⁻¹); HepG2 cells were firstly treated with pcDNA3.1-IGF2BP2 and pcDNA3.1-NC respectively for 6 h, then with 8 μmol·L⁻¹ NaAsO₂ for 24 h to establish a IGF2BP2 overexpression cell model (the experiment was divided into 4 groups: control, NaAsO₂, NaAsO₂+pcDNA3.1-IGF2BP2, and NaAsO₂+pcDNA3.1-NC); finally the cells were subject to 100 nmol·L⁻¹ insulin stimulation for 30 min. Glycogen and glucose in HepG2 cells were determined by glycogen and glucose assay kits; mRNA expression levels of IGF2BP2 were measured by quantitative real-time PCR; protein expression levels of IGF2BP2, PPAR-γ, and GLUT4 in HepG2 were detected by Western blot (WB); and the binding of IGF2BP2 to PPAR-γ and PPAR-γ to GLUT4 was verified by co-immunoprecipitation (CO-IP) experiment. Results The results of CCK8 experiment showed a dose-effect relationship between NaAsO₂ concentration and cell viability. When the concentration of NaAsO₂ was ≥4 μmol·L⁻¹ , the cell viabilities were lower than that of the control group (P <0.05). With the increasing dose of NaAsO₂ infection, reduced glucose consumption and glycogen levels in HepG2 cells were found in the 2, 4, and 8 μmol·L⁻¹ NaAsO₂ treatment groups compared to the control group (P <0.05). The difference between the mRNA expression level of IGF2BP2 in the HepG2 cells treated with 4 or 8 μmol L⁻¹ NaAsO₂ and the control group was significant (P <0.05). In the IGF2BP2 overexpression cell model, compared with the control group, glucose consumption and glycogen levels were lowered in the NaAsO₂ group (P <0.05), the mRNA expression level of IGF2BP2 and the protein expression levels of IGF2BP2, PPAR-γ, and GLUT4 in the cell membrane were all decreased (P <0.05). Compared with the NaAsO₂ group, the glucose consumption and glycogen levels were increased in the NaAsO₂+pcDNA3.1-IGF2BP2 group (P <0.05), and the mRNA expression level of IGF2BP2 and the protein expression levels of IGF2BP2, PPAR-γ, and GLUT4 in the cell membrane were all increased (P <0.05). The results of CO-IP experiments showed that IGF2BP2 interacted with PPAR-γ as well as PPAR-γ with GLUT4 protein. Conclusion IGF2BP2 is involved in arsenic exposure-induced insulin resistance in HepG2 cells by acting on the PPAR-γ/GLUT4 pathway.

Objective To investigate the effect of Ching Shum Pills(CSP)for alleviating non-alcoholic fatty liver disease(NAFLD)and the underlying mechanism.Methods In a mouse model of NAFLD,the therapeutic effect of CSP was evaluated by measuring serum glucose,lipid profiles(TC,TG,LDL-C,HDL-C),and hepatic function markers.Network pharmacology was employed to identify active compounds in CSP and their targets using TCMSP,HERB,SwissTargetPrediction,GeneCards,OMIM,and DisGeNET.Protein-protein interaction(PPI)networks,Gene Ontology(GO),and KEGG pathway analyses were conducted.Molecular docking(AutoDock Vina)was used to assess the compound-target binding affinities.Quantitative real-time PCR(qRT-PCR)was used to validate the mRNA expressions of the core genes in the liver tissue of the mouse models.Results In the mouse model of NAFLD,treatment with CSP significantly reduced body weight gain and serum TG levels of the mice,and high-dose CSP treatment resulted in obvious reduction of ALT levels and hepatic fat accumulation.Network pharmacology analysis identified quercetin and 2-monolinolenin as the key bioactives in CSP,which target TNF,AKT1,IL6,TP53,and ALB.Docking simulations suggested strong binding between the two core compounds and their target proteins.The results of qRT-PCR showed that high-fat diet induced significant downregulation of Tp53,Cpt1,and Ppara expressions in mice,which was effectively reversed by CSP treatment.Conclusion CSP can improve lipid metabolism disorders in NAFLD mice through a regulatory mechanism involving multiple targets and pathways to reduce liver fat accumulation and protect liver function.The key components in CSP such as quercetin and linolenic acid monoacylglycerol may participate in the regulation of such metabolic processes as fatty acid oxidation by targeting TP53.

OBJECTIVES: To investigate the effect of Ching Shum Pills (CSP) for alleviating non-alcoholic fatty liver disease (NAFLD) and the underlying mechanism. METHODS: In a mouse model of NAFLD, the therapeutic effect of CSP was evaluated by measuring serum glucose, lipid profiles (TC, TG, LDL-C, HDL-C), and hepatic function markers. Network pharmacology was employed to identify active compounds in CSP and their targets using TCMSP, HERB, SwissTargetPrediction, GeneCards, OMIM, and DisGeNET. Protein-protein interaction (PPI) networks, Gene Ontology (GO), and KEGG pathway analyses were conducted. Molecular docking (AutoDock Vina) was used to assess the compound-target binding affinities. Quantitative real-time PCR (qRT-PCR) was used to validate the mRNA expressions of the core genes in the liver tissue of the mouse models. RESULTS: In the mouse model of NAFLD, treatment with CSP significantly reduced body weight gain and serum TG levels of the mice, and high-dose CSP treatment resulted in obvious reduction of ALT levels and hepatic fat accumulation. Network pharmacology analysis identified quercetin and 2-monolinolenin as the key bioactives in CSP, which target TNF, AKT1, IL6, TP53, and ALB. Docking simulations suggested strong binding between the two core compounds and their target proteins. The results of qRT-PCR showed that high-fat diet induced significant downregulation of Tp53, Cpt1, and Ppara expressions in mice, which was effectively reversed by CSP treatment. CONCLUSIONS CSP can improve lipid metabolism disorders in NAFLD mice through a regulatory mechanism involving multiple targets and pathways to reduce liver fat accumulation and protect liver function. The key components in CSP such as quercetin and linolenic acid monoacylglycerol may participate in the regulation of such metabolic processes as fatty acid oxidation by targeting TP53.

Chemotherapy is an important treatment for tumors， but most patients experience varying degrees of chemotherapy- induced myelosuppression. Four properties theory of traditional Chinese medicine （TCM） has unique advantages in improving chemotherapy-induced myelosuppression. The monomers from TCM with different properties and flavors， such as cold-natured （e.g. Scutellaria baicalensis， Rhus chinensis）， cool-natured （e.g. Ligustrum lucidum， Ophiopogon japonicus）， warm-natured （e.g. Panax ginseng， Epimedium brevicornu， Curcuma longa， Angelica sinensis）， hot-natured （e.g. Cinnamomum cassia， Aconitum carmichaeli）， and neutral-natured （e. g. donkey-hide gelatin， Lycium barbarum， Rhodiola rosea， fungi）， can exert anti- myelosuppressive effects by reducing damage to hematopoietic stem/progenitor cells， improving the bone marrow hematopoietic microenvironment， inhibiting the oxidative stress response， regulating signaling pathways， so as to ultimately repaire inflammatory damage and improve hematopoietic function， thereby playing an anti-myelosuppressive role.

Objective To investigate the prevalence of Schistosoma japonicum infections in wild rodents in schistosomiasis-endemic areas of China, so as to provide insights into formulation of technical guidelines for monitoring of and the precise control strategy for S. japonicum infections in wild rodents during the elimination phase. Methods Two administrative villages where schistosomiasis was historically highly prevalent were selected each from Dongzhi County, Anhui Province, and Duchang County, Jiangxi Province as study villages. Wild rodents were captured from study villages with baited traps or cages at night in June and September, 2021. The number of rodents captured was recorded, and the rodent species was characterized based on morphologi-cal characteristics. Liver tissues were sampled from captured rodents for macroscopical observation of the presence of egg granu- lomas, and S. japonicum infection was detected simultaneously using liver tissue homogenate microscopy, examinations of mesenteric tissues for parasites, and modified Kato-Katz thick smear technique (Kato-Katz technique). A positive S. japonicum infection was defined as detection of S. japonicum eggs or adult worms by any of these methods. The rate of wild rodent capture and prevalence of S. japonicum infections in wild rodents were compared in different study villages and at different time periods, and the detection of S. japonicum infections in wild rodents was compared by different assays. Results The overall rate of wild ro- dent capture was 8.28% (237/2 861) in Dongzhi County, and the wild rodent capture rates were 9.24% (133/1 439) and 7.31% (104/1 422) in two study villages (χ² = 3.503, P = 0.061), and were 8.59% (121/1 409) and 7.99% (116/1 452) in June and September, 2021, respectively (χ² = 0.337, P = 0.561). The overall rate of wild rodent capture was 3.72% (77/2 072) in Duchang County, and the wild rodent capture rates were 6.91% (67/970) and 0.91% (10/1 102) in two study villages (χ² = 51.901, P < 0.001), and were 4.13% (39/945) and 3.37% (38/1 127) in June and September, 2021, respectively (χ² = 0.815, P = 0.365). Rattus norvegicus was the predominant rodent species captured in both counties, accounting for 70.04% (166/237) of all captured wild rodents in Dongzhi County and 88.31% (68/77) in Duchang County. No S. japonicum infection was detected in wild rodents captured in Duchang County. Nevertheless, the overall prevalence of S. japonicum infections was 51.05% (121/237) in wild rodents captured in Dongzhi County, with prevalence rates of 50.38% (67/133) and 51.92% (54/104) in two study villages (χ² = 0.098, P = 0.755), and 54.31% (63/116) and 47.93% (58/121) in September and June, 2021, respectively (χ² = 0.964, P = 0.326). Of 237 wild rodents captured in Dongzhi County, there were 140 (59.07%) rodents with visible hepatic egg granulomas, 117 (49.47%) tested positive for S. japonicum eggs by liver tissue homogenate microscopy, 34 (14.35%) tested positive for S. japonicum eggs with Kato-Katz technique; however, no adult S. japonicum worms were detected in mesenteric tissues. In addition, hepatic egg granulomas were found in all wild rodents tested positive for S. japonicum eggs with liver tissue homogenate microscopy. Conclusions The rate of wild rodent capture and prevalence of S. japonicum infection in wild rodents vary greatly in schistosomiasis-endemic areas of China, and the prevalence of S. japonicum infection is slightly higher in wild rodents captured in autumn than in summer. Liver tissue is recommended as the preferred sample for surveillance of S. japonicum infection in wild rodents, and a combination of macroscopical observation of hepatic egg granulomas and liver tissue homogenate microscopy may be a standard method for surveillance of S. japonicum infection in wild rodents.

OBJECTIVE To evaluate the effect of bundled property management under multidisciplinary coopera-tion mode on prevention and control of multidrug-resistant organisms(MDROs)in intensive care units(ICUs)and explore the evidence-based methods for prevention and control of MDROs.METHODS A control study before and after the same time period was designed,the post-intervention period was 2024 when the bundled measures were fully implemented,and the pre-intervention period was 2023.Totally 8 ICUs of general and special depart-ments of a three-A hospital in Hubei Province were recruited as research subjects,the multidisciplinary coopera-tion team was established,the bundled management measures were introduced to optimize the quality of property cleaning work.The quality of service of the property cleaning work was evaluated through surveillance of hospital-associated infections and environmental hygiene surveillance before and after the bundled measures were imple-mented.RESULTS The isolation rate of MDROs from object surfaces of ICU environment declined from 0.34％to 0.10％after the bundled management measures under multidisciplinary cooperation model were implemented(P＜0.05).The incidence of MDROs hospital-associated infections was reduced from 0.07％to 0.03％(P＜0.05);the isolation rate of MDROs from patients decreased from 14.68％to 12.69％(P＜0.05);the performance as-sessment score of the cleaning staff was raised from(85.56±7.21)points to(91.06±3.07)points,however,there was no significant difference.The hand hygiene compliance rate of the cleaning staff was raised from 42.86％to 68.52％(P＜0.05).The positive rate of random ATP fluorescent test for environmental object surfaces de-clined from 25.41％to 10.05％(P＜0.05).Other environmental hygiene indexes for the cleaning and disinfection effects were improved in varying degrees.CONCLUSION The bundled management measures under multidiscipli-nary cooperation mode boost the property service quality,enhance the cleaning staff's awareness of disinfection,prevention and control,reduce the isolation rate of MDROs in environment,and thus decrease the incidence of MDROs hospital-associated infections and prevent the transmission.

[Objective]To explore the anti-cerebral ischemia mechanism of Rhubarb root and rhizome by ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF/MS)combined with network pharmacology and in vitro experiment.[Methods]The active components of Rhubarb root and rhizome in rat serum samples were identified by UPLC-Q-TOF/MS.The potential targets of Rhubarb root and rhizome in blood components were obtained by Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP)and Swiss Target Prediction.The related targets of ischemic stroke(IS)were obtained from Genome Annotation Database Platform(GeneCards),Online Mendelian Inheritance in Man(OMIM)database and Therapeutic Target Database(TTD).The intersection targets were obtained by using Venny 2.1.0 software and imported into the STRING database for protein-protein interaction(PPI)network analysis.Cytoscape 3.7.2 software was employed to visualize and identify the core targets.Gene ontology(GO)enrichment function analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)signal pathway enrichment analysis were conducted to predict the mechanism of action.Molecular docking was performed by AutoDock Vina.Finally,the network pharmacological prediction results were verified by in vitro experiments.[Results]A total of 15 active components were identified in serum containing Rhubarb root and rhizome(SR),and there were 87 intersection targets between Rhubarb root and rhizome and IS.KEGG enrichment analysis showed that Rhubarb root and rhizome may alleviate IS through phosphatidylinositol 3-kinase/protein kinase B(PI3K/AKT)and nuclear factor-κB(NF-κB)signaling pathways.Molecular docking results showed that the core components had a strong binding ability to the key targets of Toll-like receptor 4(TLR4)/myeloid differentiation primary response gene 88(MyD88)/NF-κB signaling pathway.In vitro experiment demonstrated that SR reduced the production of reactive oxygen species(ROS)induced by oxygen-glucose deprivation/reoxygenation(OGD/R)in BV2 cells.It also increased the activity of superoxide dismutase(SOD)and glutathione peroxidase(GSH-Px),while decreasing the levels of malondialdehyde(MDA)and nitric oxide(NO).Additionally,SR reduced the levels of pro-inflammatory factors,increased the levels of anti-inflammatory factors in BV2 cells induced by OGD/R,and decreased the protein expression of TLR4,MyD88 and NF-κB in BV2 cells.[Conclusion]Rhubarb root and rhizome protects BV2 microglia from OGD/R-induced injury by inhibiting oxidative stress and inflammatory response,and its mechanism may be related to regulation of TLR4/MyD88/NF-κB signaling pathway.

Cervical spinal cord injury without fracture-dislocation (CSCIWFD) is referred to as a special type of cervical spinal cord injury characterized by traumatic spinal cord dysfunction and no significant bony structural abnormalities on imagines. Duo to the high risk of missed diagnosis during the initial consultation, CSCIWFD may lead to progressive neurological deterioration or even complete paralysis, severely impacting patients′ prognosis. Currently, there are no established consensuses over the diagnosis and treatment of CSCIWFD, such as the lack of evidence-based standards for indications of non-surgical treatment and risk of secondary neurological injury, as well as debates over the optimal timing for surgical intervention and indications for different surgical approaches. To address these issues, the Spine Trauma Group of the Orthopedic Branch of the Chinese Medical Doctor Association organized experts in the relevant fields to formulate Diagnosis and treatment guideline for acute cervical spinal cord injury without fracture- dislocation in adults ( version 2025) . Based on evidence-based medicine and the principles of scientific rigor and clinical applicability, the guidelines proposed 11 recommendations covering terminology, diagnosis, evaluation treatment, and rehabilitation, etc., aiming to standardize the management of CSCIWFD.

Vertebral refracture following percutaneous vertebral augmentation (PVA) is commonly seen in elderly patients with osteoporotic thoracolumbar compression fractures (OTLCF). It can lead to recurrent pain, loss of vertebral height, progression of kyphosis, and even neurological dysfunction, significantly impairing patients′ quality of life. Current diagnosis and treatment face multiple challenges, including high misdiagnosis rate, difficulty in choosing between surgical and non-surgical treatment options, lack of standardized surgical protocols, interference from intralesional bone cement during procedures, inadequate stability of internal fixation in osteoporotic bone, and suboptimal compliance of anti-osteoporotic therapy. Establishing a standardized diagnostic and therapeutic framework is urgently needed. To standardize the management process and improve outcomes for vertebral refractures after PVA in elderly OTLCF patients, Spinal Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field to develop Guideline for the diagnosis and treatment of vertebral refracture after percutaneous vertebral augmentation in elderly patients with osteoporotic thoracolumbar compression fractures ( version 2025), based on current literature and clinical experience, and adhering to principles of scientific rigor and clinical applicability. A total of 11 recommendations were proposed, encompassing diagnosis, treatment, and rehabilitation of vertebral refracture after PVA in elderly patients with OTLCF, aiming to provide a foundation for a standardized management.
