OBJECTIVE: To explore the clinical efficacy of orthopedic manipulation combined with daoyin exercises in the treatment of chronic lumbar disc herniation under the guidance of the theory of "equal emphasis on muscles and bones". METHODS: A total of 60 patients with single-segment, unilateral chronic lumbar disc herniation from January 2023 to January 2024 were randomly divided into the traditional physical therapy group and the manipulation treatment group, with 30 cases in each group. Among them, 3 cases were lost to follow-up in the traditional physical therapy group and 2 cases in the manipulation treatment group. There were 27 cases in the traditional physical therapy group, including 15 males and 12 females, aged 25 to 65 years old with an average of (51.96±14.42) years;the course of disease ranged from 3 to 15 months with an average of (9.89±3.32) months;11 cases were on the left side and 16 cases on the right side;15 cases were at the L4, 5 segment and 12 cases at the L5S1 segment. They were treated with lumbar traction, medium-frequency electrical stimulation and ultrasonic therapy. There were 28 cases in the manipulation treatment group, including 14 males and 14 females, aged 24 to 68 years old with an average of (49.82±14.85) years old;the course of disease ranged from 3 to 14 months with an average of (9.61±3.05) months;15 cases were on the left side and 13 cases on the right side;17 cases were at the L4, 5 segment and 11 cases at the L5S1 segment. They were treated with orthopedic manipulation combined with daoyin exercises. The visual analogue scale (VAS), Oswestry disability index (ODI) and bilateral erector spinae muscle tone were compared between the two groups before treatment, after 2 weeks and 4 weeks of treatment. RESULTS: The two groups of patients were followed up and evaluated before treatment, 2 weeks and 4 weeks after treatment. The VAS of the manipulation treatment group and the traditional physical therapy group decreased from (5.46±0.99) and (5.41±1.05) points before treatment to (1.75±0.79) and (2.29±0.82) points after 4 weeks of treatment, respectively. Both groups were significantly improved after treatment compared with before treatment, and the differences were statistically significant (P<0.05);and the manipulation treatment group was better than the traditional physical therapy group at 4 weeks of treatment, with a statistically significant difference (P<0.05). The ODI of the manipulation treatment group and the traditional physical therapy group before treatment was (20.25±2.72) and (18.96±2.52) points, respectively, which decreased to (15.46±1.88) and (16.56±2.01) points after 2 weeks of treatment, and to (11.54±1.23) and (12.85±1.72) points after 4 weeks of treatment. Both groups were significantly improved after treatment compared with before treatment, and the differences were statistically significant (P<0.05), and the ODI in the manipulation treatment group was better than that in the traditional physical therapy group after treatment (P<0.05). There was no significant statistical difference in the displacement of erector spinae muscle tone between the healthy side and the affected side in both the manipulation treatment group and the traditional physical therapy group before treatment (P>0.05). After 2 weeks of treatment, the displacement values of erector spinae muscle tone on the healthy side in the manipulation treatment group and the traditional physical therapy group were (6.68±0.81) mm and (6.45±0.65) mm, respectively, and those on the affected side were (5.87±0.82) mm and (5.61±0.84) mm, respectively. After 4 weeks of treatment, the displacement values of erector spinae muscle tone on the healthy side in the manipulation treatment group and the traditional physical therapy group were (7.51±0.75) mm and (7.04±0.63) mm, respectively, and those on the affected side were (6.87±0.78) mm and (6.33±0.82) mm, respectively. The displacement values of erector spinae muscle tone on both the healthy and affected sides in both groups were significantly higher than those before treatment, and the differences were statistically significant (P<0.05);the displacement of erector spinae muscle tone in the manipulation treatment group after 4 weeks of treatment was better than that in the traditional physical therapy group, with a statistically significant difference (P<0.05). CONCLUSION Orthopedic manipulation combined with daoyin exercises can effectively improve the symptoms and lumbar function of patients with chronic lumbar disc herniation, and has more advantages in improving the tone of the erector spinae muscle.

Aim To explore the effect of astragalosideⅣ(AS-Ⅳ)on lipopolysaccharide(LPS)-induced po-larization and migration of RAW 264.7 macrophages and the underlying mechanism.Methods 1 mg·L-1 LPS was used to construct cell migration model.Scratch assay was utilized to determine cell migration rate.Immunofluorescence staining was utilized to de-tect the expression and location of F4/80,iNOS and Arg-1.CCK-8 assay was used to determine the viabili-ty of RAW 264.7 cells.Griess assay was used to measure NO content.Molecular docking was used to analyze the interaction between AS-Ⅳ and the core tar-gets such as cGAS and STING protein.Western blot was employed to detect the expression of iNOS,Arg-1,cGAS,STING,NF-κB p65 and p-NF-κB p65 protein.Results AS-Ⅳ significantly inhibited the migration and M1 polarization of RAW 264.7 cells induced by LPS.Moreover,AS-Ⅳ could interact with cGAS and STING protein,especially cGAS.Further Western blot assay showed that AS-Ⅳ significantly downregulated the expression of iNOS,cGAS,STING and p-NF-κB p65 protein.Conclusions AS-Ⅳ could promote mac-rophage M1 to M2 polarization,thereby inhibited mac-rophage migration through restraining the cGAS/STING/NF-κB signaling pathway,which provides a new therapeutic target for AS-Ⅳ to improve the early inflammatory response of AS.

A method for simultaneous determination of 21 kinds of Aconitum alkaloids(ATS)in biological specimens and infused liquor using ultra-performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS)was developed.The biological samples were pretreated with methanol-acetonitrile(1∶2,V/V)for protein precipitation,while infused liquors were diluted 100-fold with acetonitrile,followed by centrifugation,and filtration by a 0.22-μm membrane.Chromatographic separation was carried out on an EC-C18 column using gradient elution with the mixture of 10 mmol/L ammonium acetate and 0.2%formic acid as mobile phase A and acetonitrile as mobile phase B.With this method,all the analytes were separated within 9.5 min.The samples were detected in positive ESI mode with dynamic multiple reaction monitoring(MRM)and quantified via external standard calibration.The results showed that the concentrations of the analytes in the range of 2-1000 ng/mL had excellent linearity(R2>0.9992)with the peak area.The developed method was successfully used for detection of 21 kinds of aconitum alkaloids,with limits of detection of 0.5-2 ng/mL,quantification limits of 2-6 ng/mL,intra/inter-day precision≤6.0%,spiked recoveries of 89.4%-100.9%,extraction recoveries of 74.2%-104.4%,and matrix effects ranging from-11.1%to 9.2%in blood/urine.The method was applied to detection of 12 samples from 4 fatal aconite poisoning cases,and all 21 kinds of ATS with total alkaloid concentrations of 0.04-4.18 μg/mL in blood and 154.96-422.83 μg/mL in medicinal liquors were detected.Tissue distribution revealed that the order of concentrations from highest to lowest is as follows:urine(157.22 μg/mL)>gastric contents(51.37 μg/mL)>kidney(21.6 μg/g)>whole blood(4.18 μg/mL)>liver(0.03 μg/g).This method showed many advantages such as simple pretreatment,low detection limits,accurate quantification,broad analyte coverage,and superior anti-interference capability in complex matrices,proving ideal for forensic and toxicological analysis of aconitum alkaloids.

Exercise-induced metabolic remodeling is a fundamental adaptive process whereby the body reorganizes systemic and cellular metabolism to meet the dynamic energy demands posed by physical activity. Emerging evidence reveals that such remodeling not only enhances energy homeostasis but also profoundly influences immune function through complex molecular interactions involving glucose, lipid, and protein metabolism. This review presents an in-depth synthesis of recent advances, elucidating how exercise modulates immune regulation via metabolic reprogramming, highlighting key molecular mechanisms, immune-metabolic signaling axes, and the authors’ academic perspective on the integrated “exercise-metabolism-immunity” network. In the domain of glucose metabolism, regular exercise improves insulin sensitivity and reduces hyperglycemia, thereby attenuating glucose toxicity-induced immune dysfunction. It suppresses the formation of advanced glycation end-products (AGEs) and interrupts the AGEs-RAGE-inflammation positive feedback loop in innate and adaptive immune cells. Importantly, exercise-induced lactate, traditionally viewed as a metabolic byproduct, is now recognized as an active immunomodulatory molecule. At high concentrations, lactate can suppress immune function through pH-mediated effects and GPR81 receptor activation. At physiological levels, it supports regulatory T cell survival, promotes macrophage M2 polarization, and modulates gene expression via histone lactylation. Additionally, key metabolic regulators such as AMPK and mTOR coordinate immune cell energy balance and phenotype; exercise activates the AMPK-mTOR axis to favor anti-inflammatory immune cell profiles. Simultaneously, hypoxia-inducible factor-1α (HIF-1α) is transiently activated during exercise, driving glycolytic reprogramming in T cells and macrophages, and shaping the immune landscape. In lipid metabolism, exercise alleviates adipose tissue inflammation by reducing fat mass and reshaping the immune microenvironment. It promotes the polarization of adipose tissue macrophages from a pro-inflammatory M1 phenotype to an anti-inflammatory M2 phenotype. Moreover, exercise alters the secretion profile of adipokines—raising adiponectin levels while reducing leptin and resistin—thereby influencing systemic immune balance. At the circulatory level, exercise improves lipid profiles by lowering pro-inflammatory free fatty acids (particularly saturated fatty acids) and triglycerides, while enhancing high-density lipoprotein (HDL) function, which has immunoregulatory properties such as endotoxin neutralization and macrophage cholesterol efflux. Regarding protein metabolism, exercise triggers the expression of heat shock proteins (HSPs) that act as intracellular chaperones and extracellular immune signals. Exercise also promotes the secretion of myokines (e.g., IL-6, IL-15, irisin, FGF21) from skeletal muscle, which modulate immune responses, facilitate T cell and macrophage function, and support immunological memory. Furthermore, exercise reshapes amino acid metabolism, particularly of glutamine, arginine, and branched-chain amino acids (BCAAs), thereby influencing immune cell proliferation, biosynthesis, and signaling. Leucine-mTORC1 signaling plays a key role in T cell fate, while arginine metabolism governs macrophage polarization and T cell activation. In summary, this review underscores the complex, bidirectional relationship between exercise and immune function, orchestrated through metabolic remodeling. Future research should focus on causative links among specific metabolites, signaling pathways, and immune phenotypes, as well as explore the epigenetic consequences of exercise-induced metabolic shifts. This integrated perspective advances understanding of exercise as a non-pharmacological intervention for immune regulation and offers theoretical foundations for individualized exercise prescriptions in health and disease contexts.

Objective To explore the effect of endoscopic ultrasonography(EUS)with different probes on the measurement of gastrointestinal submucosal tumor(SMT)diameter.Methods The clinical data of 356 patients(with a total of 372 lesions)initially diagnosed as SMT by EUS at the Second Affiliated Hospital of Army Medical University from January 2023 to June 2024 were analyzed retrospectively.The basic characteristics of the origin layers and pathological distribution of SMT were analyzed.The differences between the EUS-measured diameters and the actual diameters of SMT at different diameter ranges of lesions were compared.Taking the postoperative pathological diagnosis results as the gold standard,the effects of different clinicopathological features and probe types on the relative error in EUS-measured diameters of SMT were analyzed.Results Among the 372 gastrointestinal SMT lesions,lesions were more frequent in female patients,gastric lesions was the most common,and leiomyoma was the predominant pathological type.The accuracy of EUS in diagnosing SMT was 94.4%.A statistically significant difference was observed between the EUS-measured diameters and the actual diameters of SMT(P<0.05).There were significantly differences in various ranges of lesions between the EUS-measured diameters and the actual diameters(P<0.05).The gender,age,lesion location,and pathological type had no significant effect on the relative error of EUS-measured diameters(P>0.05);while probe types had a significant effect on the relative error of EUS-measured diameters(P<0.05).For lesions with an actual diameter of 2.0 to 3.9 cm,the relative error of SMT diameters measured by small-probe EUS was significantly greater than that by large-probe EUS(P<0.05).Conclusion Large-probe EUS exhibits a smaller relative error in measuring the diameter of SMT with a diameter of≥2.0 cm.Therefore,large-probe EUS is recommended for the examination of SMT with an estimated diameter exceeding 2.0 cm.

Objective:To investigate the correlation between serum albumin, urea nitrogen and Fazekas scores and cognitive function scores in patients with mild and medium ischemic stroke.Methods:Clinical data of 160 patients with acute ischemic stroke with the National Institutes of Health Stroke Scale (NIHSS)≤7 scores admitted to the Department of Neurology of the First Affiliated Hospital of Hainan Medical College from June 2021 to April 2023 were selected for a cross-sectional study. According to the Montreal Cognitive Assessment (MoCA) score, they were divided into normal cognitive group (28 cases) (MoCA≥26 scores), mild to moderate cognitive impairment group (74 cases) (MoCA 15-<26 scores), and severe cognitive impairment group (58 cases) (MoCA<15 scores). Demographic characteristics, serological indicators and imaging data of patients were collected, and the correlation between serum albumin, urea nitrogen and Fazekas scores and the total score of MoCA and the scores of each cognitive domain was analyzed. One-way ANOVA was used for comparison between the normal distribution and homogeneous variance data sets, LSD analysis was used for pairwise comparison, Kruskal-Wallis H test was used between the skew distribution or heterogeneous variance data sets. Bonferroni correction analysis was used for pairwise comparison. Chi-square test or Fisher exact probability method was used after the comparison between the count data sets. Spearman Spearman correlation analysis was performed on serum albumin, urea nitrogen and Fazekas scores with MoCA scores and cognitive domain scores. Multivariate ordered Logistic regression was used to analyze the independent risk factors of cognitive function in acute stage of mild and medium ischemic stroke patients. Results:The incidence of cognitive impairment in patients with acute mild and medium ischemic stroke was 82.50% (132/160). Comparison of age ((56.71±7.35), (60.32±10.20), (66.40±11.88) years old), sex (male/female: (23/5, 58/16, 33/25)), the proportion of education level above high school (25.0%(7/28), 16.2%(12/74), 6.9%(4/58)), hemoglobin ((149.26±14.91), (144.85±16.85), (137.63±17.22) g/L), albumin (39.5 (37.0, 41.2), 38.6(35.6, 40.8), 37.4 (34.5, 39.8) g/L), urea nitrogen (5.30 (4.00, 6.60), 4.81 (4.00, 6.32), 5.86 (4.55, 6.97) mmol/L), Hamilton Anxiety Scale (HAMA) score (5.0 (2.0, 10.0), 7.5 (5.0, 11.0), 10.0 (6.0, 14.3) scores),Hamilton Depression Scale (HAMA) score (5.5 (3.0, 12.5), 7.0 (4.0, 11.0), 9.5 (5.0, 14.0) scores), and Fazekas score (2.00 (1.25, 3.00), 2.00 (1.00, 4.00), 3.00 (2.00, 5.00) scores) among cognitive normal group, mild to moderate cognitive impairment group, and severe cognitive impairment group of patients, the difference were statistically significant (the statistical values were F=9.68, χ 2=9.29, χ 2=30.77, F=5.31, H=7.06, H=6.71, H=12.37, H=8.91, and H=10.96, respectively;the P values were <0.001, 0.010, <0.001, 0.006, 0.029, 0.035, 0.002, 0.012, and 0.004, respectively ). The total score of MoCA was negatively correlated with Fazekas score and serum urea nitrogen, but positively correlated with serum albumin ( r s values were -0.250, -0.168, and 0.212, respectively; P values were 0.001, 0.036, and 0.009, respectively). Serum albumin was positively correlated with scores in visual space and execution, naming, attention and orientation, serum urea nitrogen was negatively correlated with scores in language and orientation, and Fazekas score was negatively correlated with scores in visual space and execution, orientation, attention and language ( r s values were 0.291, 0.196, 0.191, 0.209, -0.205, -0.180, -0.248, -0.193, -0.188, and -0.183, respectively; P values were <0.001, 0.017, 0.020, 0.011, 0.012, 0.027, 0.002, 0.016, 0.020, and 0.023, respectively). Multiple Logistic regression analysis showed that low albumin ( OR=0.884, 95% CI: 0.813-0.963, P=0.005) and high urea nitrogen ( OR=1.195, 95% CI: 1.003-1.425, P=0.047) and high Fazekas scores ( OR=1.401, 95% CI: 1.132-1.733, P=0.002) were independent risk factors for cognitive function, while high education level was a protective factor ( OR=0.062, 95% CI: 0.019-0.202, P<0.001). Conclusion:The incidence of acute cognitive impairment is high in patients with mild and medium ischemic stroke. Higher education level is a protective factor for cognitive function. Low albumin, high urea nitrogen and high Fazekas score are independent risk factors for cognitive function.

AIM To investigate the renoprotective effects and mechanism of Caragana sinica roots,Astragali Radix and their combination use on the rat model of diabetic kidney disease(DKD).METHODS Sixty SD rats were randomly divided into the normal group,the model group,the Empagliflozin group(10 mg/kg),the C.sinica roots group(3.1 g/kg),the Astragali Radix group(3.1 g/kg),and the C.sinica roots plus Astragali Radix group(6.2 g/kg).In contrast to the intact rats of the normal group,rats of the other groups underwent left nephrectomy and intraperitoneal injection of streptozotocin(STZ)followed by 8-week intragastric gavage of the corresponding agent,during which their levels of FBG and 24 h urinary microprotein(24 h U-mAlb)were detected regularly.The rats killed at the end of the trial had their levels of Scr,BUN and Cystatin C detected;their renal pathological changes observed by HE,PAS and Masson stainings;their expressions of macrophage marker proteins CD68 and iNOS detected by immunohistochemistry;their expressions of renal JNK/SAPK pathway proteins such as JNK,p-JNK,TNF-α,IL-1β and ICAM-1 detected by Western blot;and their serum levels of TNF-α,IL-1β and ICAM-1 detected by ELISA as well.RESULTS Compared with the normal group,the model group displayed increased levels of FBG,24 h U-mAlb,BUN,Scr and Cystatin C(P＜0.01);more renal pathological damage,and increased levels of TNF-α,IL-1β and ICAM-1 in the renal tissue and serum(P＜0.01);and increased renal protein expressions of JNK and p-JNK(P＜0.01).Compared with the model group,all of the groups intervened with an agent shared decreased levels of FBG,24 h U-mAlb,BUN,Scr and Cystatin C(P＜0.05,P＜0.01);alleviated renal pathological damage,and decreased levels of TNF-α,IL-1β and ICAM-1 in renal tissue and serum(P＜0.01).There existed no group difference between the Astragali Radix group and the C.sinica roots group in terms of all indices levels(P＞0.05).The C.sinica roots plus Astragali Radix group demonstrated its superiority over either C.sinica roots group or Astragali Radix group in terms of all the indices levels(P＜0.05,P＜0.01).CONCLUSION C.sinica roots,Astragali Radix or their combination use can alleviate the renal pathological damage and improve the renal function of DKD rats through inhibiting the M1 macrophages,reducing the secretion of inflammatory factors,whose mechanism may lie in the inhibition of JNK/SAPK signal pathway activation.A better effect can be anticipated by the combination use of C.sinica roots and Astragali Radix.

AIM To investigate the impact of the combination use of Caragana sinica Radix and Astragali Radix on a rat model of diabetic kidney disease(DKD).METHODS The SD rats were randomly divided into the normal group,the model group,the Engelgin group,the Caragana sinica Radix group,the Astragali Radix group and the Caragana sinica Radix-Astragali Radix compatibility group,with 10 rats in each group.Following the successful establishment of a DKD model by unilateral amputate renal combined with intraperitoneal injection of streptozotocin(STZ),the corresponding gastric gavage of drugs were administered for 8 weeks.The rats had their 24 h urinary microalbumin(24 h U-mALB)detected at 0,4 and 8 weeks;their levels of Scr,BUN,CysC,MDA and SOD activity detected by ELISA;their renal ROS expression detected by fluorescence probe method;their renal pathological changes observed by HE,PAS,Masson and PASM-Masson staining;their renal expressions of NOX4,Drp1,MFN2 and P62 detected by immunohistochemistry;and their renal expressions of PINK1,MFN2,Parkin,LC3-Ⅱ/Ⅰ,P62 and p-Drp1 proteins detected by Western blot.RESULTS Compared with the model group,each treatment group displayed lower contents of 24 h U-mALB,BUN,Scr and CysC in the serum of rats(P＜0.01);reduced pathological structure damage of the renal tissue;decreased MDA level in serum and kidney(P＜0.01);increased SOD activity(P＜0.01);increased renal protein expressions of PINK1,MFN2,Parkin and LC3-Ⅱ/Ⅰ(P＜0.05,P＜0.01);and decreased protein expressions of p-Drp1 and P62(P＜0.01).And the Astragali Radix group and the Caragana sinica Radix-Astragali Radix compatibility group took the lead(P＜0.05,P＜0.01).CONCLUSION Upon the rat model of DKD,the compatibility of Caragana sinica Radix and Astragali Radix may alleviate their renal pathological damage and improve their renal function by activating the mitochondrial autophagy to improve mitochondrial dynamics and inhibit their oxidative stress via PINK1/MFN2/Parkin pathway.
