ObjectiveTo explore the establishment of a rat model of diabetic macrovascular atherosclerosis （DMA） with Qi and Yin deficiency syndrome induced by high-fat diet， streptozotocin （STZ）， and Yin-depleting herbs， and to evaluate its biological characteristics. MethodsForty SD rats were randomly divided into a blank group （n=10） and a modeling group （n=30）. Except for the blank group， rats in the model group were fed a high-fat diet for 4 weeks， followed by intraperitoneal injection of STZ （30 mg·kg^-1） to establish a diabetic model. Twenty-four successfully modeled diabetic rats were randomly divided into a model group （n=7）， a Qi and Yin deficiency syndrome group （n=8）， and a counter-syndrome group （n=9）. Except for the model group， rats received intragastric administration of Yin-depleting herbs （1.2 g·kg^-1） for 8 weeks. The counter-syndrome group was further treated with Shenqi compound formula （1.69 g·kg^-1） for an additional 8 weeks. General condition and body weight were recorded， and syndrome-related indicators were assessed， including precordial temperature， skin moisture content， grip strength， open-field test performance， and tongue appearance. Serum levels of vascular endothelial growth factor （VEGF）， endothelin-1 （ET-1）， vascular cell adhesion molecule-1 （VCAM-1）， insulin-like growth factor-1 （IGF-1）， and monocyte chemotactic protein-1 （MCP-1） were measured by enzyme-linked immunosorbent assay （ELISA）. Fasting blood glucose， blood lipids， hemorheological parameters， and coagulation function were analyzed using an automatic biochemical analyzer. Vascular ultrasound and hematoxylin-eosin （HE） staining were used to evaluate vascular lesions. ResultsIn terms of syndrome manifestations， compared with the blank group， body weight increased rapidly during the first 5 weeks in the model， Qi and Yin deficiency， and counter-syndrome groups. After STZ injection combined with Yin-depleting herbal administration at week 5， body weight decreased significantly （P<0.01） and continued to decline until the end of the experiment. Rats exhibited decreased activity， irritability， coarse and yellowish fur with obvious shedding， polydipsia， polyphagia， frequent urination， and dry stools， which were most pronounced in the Qi and Yin deficiency group. Grip strength decreased， peak activity time occurred earlier， total distance in the open-field test was reduced， and residence time was prolonged. Precordial temperature decreased （P<0.01）， while paw temperature increased （P<0.05）， and skin moisture and oil content were reduced （P<0.05， P<0.01）. In terms of disease-related indicators， compared with the blank group， fasting blood glucose was significantly increased （>16.7 mmol·L^-1） in the model and Qi and Yin deficiency groups， and blood lipid levels were significantly elevated （P<0.05）. Vascular-related factors ET-1， MCP-1， VCAM-1， and VEGF were significantly increased （P<0.05，P<0.01）， while IGF-1 was significantly decreased （P<0.01）. Pathological examination of the aortic valve showed valvular thickening and structural disorganization. Carotid artery examination revealed discontinuity of the intima， foam cell accumulation beneath the intima， disordered smooth muscle arrangement， and widened intercellular spaces. Compared with the model group， ET-1， MCP-1， and VEGF levels were significantly decreased in both the Qi and Yin deficiency group and the counter-syndrome group. The reductions in ET-1 and MCP-1 were more pronounced in the Qi and Yin deficiency group （P<0.01）， while the decrease in VCAM-1 was more significant in the counter-syndrome group （P<0.05）. Compared with the blank group， the Qi and Yin deficiency group showed significantly prolonged activated partial thromboplastin time （APTT）， thrombin time （TT）， and prothrombin time （PT） （P<0.01）. The erythrocyte deformability index （TK）， erythrocyte sedimentation rate， erythrocyte electrophoresis index， and whole blood low-shear viscosity all showed increasing trends. Vascular ultrasound revealed reduced arterial blood flow velocity， increased vascular resistance， and intimal thickening without plaque formation. The aortic intima showed no obvious overall thickening， with only occasional localized thickening and foam cell presence， and carotid artery injury was observed. ConclusionA rat model of DMA with Qi and Yin deficiency syndrome was successfully established using high-fat diet feeding combined with STZ injection and Yin-depleting herbal administration. Shenqi compound formula effectively alleviated Qi and Yin deficiency syndrome， regulated glucose and lipid metabolism， improved hemorheological and coagulation function， reduced vascular lesion severity， and demonstrated potential for early prevention and treatment of DMA.

Accurate analysis of metal nanoparticles(MNPs)in sediments is a prerequisite for assessing the ecological risks of MNPs in aquatic environmental sediments.In this study,an analytical method for quantitative detection of concentration and particle size distribution of silver-containing nanoparticles(Ag-NPs),zinc-containing nanoparticles(Zn-NPs),cerium-containing nanoparticles(Ce-NPs),and titanium-containing nanoparticles(Ti-NPs)in sediments was established based on ultrasonic extraction-single particle inductively coupled plasma mass spectrometry(SP-ICP-MS).The effects of sample preparation conditions such as extraction solvent type,solid-liquid ratio,ultrasonic time,and settling time on the recovery of MNPs were investigated.The results showed that the extraction of MNPs from sediment by distilled water could effectively eliminate the high background signal interference introduced by the extractant under the conditions of solid-liquid ratio of 1∶400(g∶mL),ultrasonic extraction time of 1 h and settling time of 3 h.The detection limits for particle size of Ag-NPs,Zn-NPs,Ce-NPs and Ti-NPs in sediments were 31,35,26 and 85 nm,respectively,while the detection limits of particle concentrations were 1.21×104,1.90×104,5.26×107 and 1.48×107 particles/g,respectively.The spiking recoveries of Ag-NPs,Zn-NPs,Ce-NPs and Ti-NPs in sediments were 62.1％-108.7％,with relative standard deviations below 10％.This method could rapidly,accurately and simultaneously determine the concentration and particle size distribution of various MNPs in sediments,and was successfully applied to analysis of Ag-NPs,Zn-NPs,Ce-NPs,and Ti-NPs in authentic marine sediments.

The electrocatalytic nitrate reduction reaction(NO3RR)presents a sustainable pathway for large-scale ammonia production,yet it faces significant challenges due to proton supply limitations caused by the high energy barrier for water dissociation,which slows ammonia(NH3)generation.Herein,a palladium(Pd)-modified copper-cobalt(CuCo)hollow fiber penetration electrode that enabled H2 injection through its hollow structures,thereby enhancing proton availability for NO3RR was developed.The active Pd component efficiently dissociated H2,facilitating active hydrogen(*H)spillover and speeding up the cascade NO3RR process on Cu and Co sites.As a result,a half-cell energy efficiency of 39.53%and an NH3 Faradaic efficiency(FE)of 97.11%±1.17%at-0.1 V(vs RHE)were achieved,comparable to state-of-the-art systems.Importantly,the H2-assisted approach prevented the oxidation of active Cu and Co phases,demonstrating exceptional stability with less than 5.6%decay in current density(267 mA/cm2)and retention of NH3 FE at 94.8%after over 70 h of electrolysis.These findings offered valuable insights into proton supply pathways and design of NO3RR electrodes.

Objective To investigate the relationship between the serum FMS-like tyrosine kinase 3 ligand(Flt3L),progranulin(PGRN)levels and the disease risk and disease outcome of patients with acute lympho-blastic leukemia(ALL).Methods A total of 104 patients with ALL admitted to the hospital from September 2019 to September 2021 were selected as the research subjects.ALL patients were divided into the low-risk group(n=34),the medium-risk group(n=39),and the high-risk group(n=31)according to the disease risk.The levels of serum Flt3L and PGRN of the patients at admission were detected by enzyme-linked immu-nosorbent assay.Pearson correlation analysis was used to analyze the relationship between serum Flt3L,PGRN in ALL patients and the risk of ALL disease.According to the follow-up results of ALL patients,they were divided into the good prognosis group(n=81)and the poor prognosis group(n=23).The receiver oper-ating characteristic curve and the area under the curve(AUC)were used to analyze the evaluation value of se-rum Flt3L and PGRN for the prognosis of ALL patients,and multivariate Cox regression was used to analyze the prognostic risk factors of ALL patients.Results The serum Flt3L levels in the low-risk group and the medium-risk group were higher than those in the high-risk group,and the difference was statistically signifi-cant(P＜0.05).The serum PGRN levels in the low-risk group and the medium-risk group were lower than those in the high-risk group,and the difference was statistically significant(P＜0.05).Serum Flt3L in ALL patients was negatively correlated with the risk of ALL disease(r=-0.461,0.593,P＜0.05).Serum PGRN in ALL patients was positively correlated with the risk of ALL disease(r=0.593,P＜0.05).The proportions of white blood cell count ≥50 × 109/L,hemoglobin＜90 g/L,and serum PGRN level in the poor prognosis group were higher than those in the good prognosis group,while the serum Flt3L level was lower than that in the good prognosis group,and the differences were statistically significant(P＜0.05).The AUC of serum Flt3L and PGRN in evaluating the prognosis of ALL patients were 0.762(95％CI:0.717-0.816),0.815(95％CI:0.764-0.863),and 0.915(95％CI:0.866-0.964),respectively.White blood cell count ≥50 × 109/L,hemoglobin＜90 g/L,Flt3L＜92.07 pg/mL,and PGRN≥335.14 pg/mL were risk factors affecting the prognosis of ALL patients(P＜0.05).Conclusion The levels of serum Flt3L and PGRN in ALL patients are related to the disease risk and disease outcome of ALL.The combined detection of the two has a good eval-uation value for the prognosis of adult ALL patients.

BACKGROUND:Acute exercise tends to cause skeletal muscle tissue damage and lipid metabolism disorders in vivo,but the mechanism by which acute exercise combined with electroacupuncture modulates metabolic and autophagic pathways in vivo is unclear. OBJECTIVE:To observe the changes in metabolic enzymes and autophagy levels in skeletal muscle of rats subjected to acute exercise by electroacupuncture at the acupoints of"Zusanli"and"Huantiao." METHODS:Fifty male Sprague-Dawley rats were randomly divided into three groups:quiet control group(n=10),model group(n=20),and reverse electroacupuncture group(n=20).The latter two groups were set up with two time points,i.e.immediate and 3 hours after exercise groups(n=10 per time point).The model group and the reverse electroacupuncture group underwent acute exercise training after adaptive treadmill training.The rats in the reverse electroacupuncture group underwent electroacupuncture treatment(parameters:electroacupuncture on both sides of the rats at the acupoints of"Zusanli"and"Huantiao,"continuous wave,frequency of 2 Hz,intensity of 2 mA,leaving the needle in the body for 30 minutes,once a day for 7 consecutive days)before treadmill training.Bilateral gastrocnemius muscle tissues were taken under anesthesia immediately after exercise and 3 hours after exercise,and hematoxylin-eosin staining was used to observe the histopathological changes of rat skeletal muscle.ELISA kit was used to detect the activities of hepatic lipase,fatty acid synthase,hormone-sensitive lipase,and carnitine palmitoyltransferase 1 in rat skeletal muscle tissues.Immunohistochemistry and western blot were used to detect the changes in the expression of autophagy genes. RESULTS AND CONCLUSION:After hematoxylin-eosin staining,the arrangement of gastrocnemius muscle fibers in the model group was disturbed,swollen and ruptured immediately after exercise and 3 hours after exercise.In the reverse electroacupuncture group,gastrocnemius muscle fibers were tightly arranged and the number of swollen and ruptured cells was greatly reduced immediately after exercise and 3 hours after exercise,and there was no significant difference when compared with the quiet control group.Compared with the quiet control group,the activities of hepatic lipase and fatty acid synthase were lower while the activities of lipoprotein lipase,hormone-sensitive lipase,and carnitine palmitoyltransferase 1 were higher in the model group and the reverse electroacupuncture group 3 hours after exercise(P＜0.05 or P＜0.01).Compared with the model group,the activities of lipoprotein lipase and carnitine palmitoyltransferase 1 were higher in the reverse electroacupuncture group immediately after exercise(P＜0.05),while the activity of lipoprotein lipase was higher and the activity of hormone-sensitive lipase was lower in the reverse electroacupuncture group 3 hours after exercise(P＜0.01).Immunohistochemical results showed that compared with the quiet control group,the expression of P62,autophagy-related gene 5 and autophagy-related gene 7 was higher in the model group immediately and 3 hours after exercise,as well as in the reverse electroacupuncture group immediately after exercise(P＜0.05 or P＜0.01);compared with the model group,the expression of P62 and autophagy-related gene 7 was lower in the reverse electroacupuncture group immediately and 3 hours after exercise(P＜0.05).Western blot results showed that the protein expression of P62 and autophagy-related gene 7 in the reverse electroacupuncture group was lower than that in the model group immediately after exercise(P＜0.05);the protein expression of Parkin in the model group was higher than that in the quiet control group immediately and 3 hours after exercise(P＜0.05);and the protein expression of Parkin in the reverse electroacupuncture group was lower than that in the model group immediately and 3 hours after exercise(P＜0.05).To conclude,acute exercise induces disorders,swelling and rupture of gastrocnemius muscle fibers in rats and electroacupuncture on both sides of the acupoints of"Zusanli"and"Huantiao"can improve the level of lipid metabolism and regulate autophagy cells in rat skeletal muscle,preventing the disorders of lipid metabolism and damage of gastrocnemius muscle tissues caused by acute exercise.The mechanism may be closely related to the regulation of autophagy-related factor P62,autophagy-related gene 5,autophagy-related gene 7,and Parkin protein expression to promote the occurrence of autophagy or regulate the autophagy pathway in rat skeletal muscle cells.

Objective To evaluate the clinical efficacy of acupuncture at Four Gates(bilateral LI4 and LR3)and other acupoints in treating postoperative pain after laparoscopic inguinal hernia repair and to explore its potential mechanism of action.Methods Sixty patients who underwent tension-free laparoscopic inguinal hernia repair at the Third Affiliated Hospital of Guangzhou University of Chinese Medicine between June 2024 and January 2025 and developed postoperative pain were enrolled.They were randomly divided into an observation group(n=30)and a control group(n=30)using a random number table.The control group received standard postoperative care,while the observation group received additional acupuncture at Four Gates and other acupoints(administered at 0 hour and 24 hours postoperatively).Clinical efficacy was assessed after 24 hours.Changes in the Numerical Rating Scale(NRS)for pain and the Bruggrmann Comfort Scale(BCS)were recorded.Serum levels of white blood cells(WBC),C-reactive protein(CRP),erythrocyte sedimentation rate(ESR),and cortisol(COR)were compared before and after treatment.Safety and adverse reactions were also evaluated.Results(1)After 4 hours and 24 hours of treatment,the NRS scores in the observation group were significantly improved(P＜0.05).Additionally,the observation group showed a significantly greater improvement in NRS scores than the control group during the same period,with statistically significant differences(P＜0.05).(2)After 4 hours and 24 hours of treatment,the BCS scores of both groups of patients were significantly improved(P＜0.05).The observation group showed a significantly greater improvement in BCS scores than the control group,with statistically significant differences(P＜0.05).(3)After treatment,the levels of WBC,CRP,and ESR in the observation group were significantly lower than those in the control group(P＜0.05).There was no statistically significant difference in COR levels between the two groups(P＞0.05).After treatment,the WBC levels in the observation group were slightly lower than before treatment,but the difference was not statistically significant(P＞0.05),while the WBC levels in the control group were significantly higher than before treatment(P＜0.05).(4)The overall response rate in the observation group was 96.70％(29/30),while that in the control group was 56.77％(17/30).The efficacy of the observation group was superior to that of the control group,with a statistically significant difference(P＜0.05).(5)No significant adverse reactions occurred in either the observation group or the control group.There was no statistically significant difference in the incidence of adverse reactions between the two groups(P＞0.05).Conclusion Acupuncture at Four Gates and other acupoints significantly alleviates postoperative pain,enhances patient comfort,and demonstrates excellent clinical efficacy with high safety.The treatment modulates postoperative WBC,CRP,ESR,and COR levels,suggesting systemic anti-inflammatory and stress-regulatory effects.

Tumor drug resistance is an important problem in the failure of chemotherapy and targeted drug therapy, which is a complex process involving chromatin remodeling. SWI/SNF is one of the most studied ATP-dependent chromatin remodeling complexes in tumorigenesis, which plays an important role in the coordination of chromatin structural stability, gene expression, and post-translation modification. However, its mechanism in tumor drug resistance has not been systematically combed. SWI/SNF can be divided into 3 types according to its subunit composition: BAF, PBAF, and ncBAF. These 3 subtypes all contain two mutually exclusive ATPase catalytic subunits (SMARCA2 or SMARCA4), core subunits (SMARCC1 and SMARCD1), and regulatory subunits (ARID1A, PBRM1, and ACTB, etc.), which can control gene expression by regulating chromatin structure. The change of SWI/SNF complex subunits is one of the important factors of tumor drug resistance and progress. SMARCA4 and ARID1A are the most widely studied subunits in tumor drug resistance. Low expression of SMARCA4 can lead to the deletion of the transcription inhibitor of the BCL2L1 gene in mantle cell lymphoma, which will result in transcription up-regulation and significant resistance to the combination therapy of ibrutinib and venetoclax. Low expression of SMARCA4 and high expression of SMARCA2 can activate the FGFR1-pERK1/2 signaling pathway in ovarian high-grade serous carcinoma cells, which induces the overexpression of anti-apoptosis gene BCL2 and results in carboplatin resistance. SMARCA4 deletion can up-regulate epithelial-mesenchymal transition (EMT) by activating YAP1 gene expression in triple-negative breast cancer. It can also reduce the expression of Ca²⁺ channel IP3R3 in ovarian and lung cancer, resulting in the transfer of Ca²⁺ needed to induce apoptosis from endoplasmic reticulum to mitochondria damage. Thus, these two tumors are resistant to cisplatin. It has been found that verteporfin can overcome the drug resistance induced by SMARCA4 deletion. However, this inhibitor has not been applied in clinical practice. Therefore, it is a promising research direction to develop SWI/SNF ATPase targeted drugs with high oral bioavailability to treat patients with tumor resistance induced by low expression or deletion of SMARCA4. ARID1A deletion can activate the expression of ANXA1 protein in HER2+ breast cancer cells or down-regulate the expression of progesterone receptor B protein in endometrial cancer cells. The drug resistance of these two tumor cells to trastuzumab or progesterone is induced by activating AKT pathway. ARID1A deletion in ovarian cancer can increase the expression of MRP2 protein and make it resistant to carboplatin and paclitaxel. ARID1A deletion also can up-regulate the phosphorylation levels of EGFR, ErbB2, and RAF1 oncogene proteins.The ErbB and VEGF pathway are activated and EMT is increased. As a result, lung adenocarcinoma is resistant to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs). Although great progress has been made in the research on the mechanism of SWI/SNF complex inducing tumor drug resistance, most of the research is still at the protein level. It is necessary to comprehensively and deeply explore the detailed mechanism of drug resistance from gene, transcription, protein, and metabolite levels by using multi-omics techniques, which can provide sufficient theoretical basis for the diagnosis and treatment of poor tumor prognosis caused by mutation or abnormal expression of SWI/SNF subunits in clinical practice.
