OBJECTIVE: To observe the clinical efficacy of 3D printing spinal external fixator combined with McKenzie therapy for patients with lumbar dics herniation (LDH). METHODS: Sixty patients with LDH between January 2022 and January 2023 were enrolled. Among them, 30 patients were given McKinsey training. According to different treatment methods, all patients were divided into McKenzie group and McKenzie + 3D printing group, 30 patients in each group. The McKenzie group provided McKenzie therapy. The McKenzie + 3D printing group were treated with 3D printing spinal external fixation brace on the basis of McKenzie therapy. Patients in both groups were between 25 and 60 years of age and had their first illness. In the McKenzie group, there were 19 males and 11 females, with an average age of (48.57±5.86) years old, and the disease duration was (7.03 ±2.39) months. The McKenzie + 3D printing group, there were 21 males and 9 females, with an average age of (48.80±5.92) years old, and the disease duration was(7.30±2.56) months. Pain was evaluated using the visual analogue scale (VAS), and lumbar spine function was assessed using the Oswestry disability index (ODI) and the Japanese Orthopaedic Association (JOA) score. VAS, ODI and JOA scores were compared between two groups before treatment and at 1, 3, 6, 9 and 12 months after treatment. RESULTS: All patients were followed up for 12 months. The VAS for the McKenzie combined with 3D printing group before treatment and at 1, 3, 6, 9, and 12 months post-treatment were(6.533±0.860), (5.133±1.008), (3.933±0.868), (2.900±0.759), (2.067±0.640), (1.433±0.504), respectively. In the McKenzie group, the corresponding scores were (6.467±0.860), (5.067±1.048), (4.600±0.968), (3.533±1.008), (2.567±0.728), (1.967±0.809), respectively. The ODI of the McKenzie group before treatment and at 1, 3, 6, 9, and 12 months post-treatment were (41.033±6.810)%, (37.933±6.209)%, (35.467±6.962)%, (27.567±10.081)%, (20.800±7.531)%, (13.533±5.158)%, respectively. For the McKenzie combined with 3D printing group, the corresponding ODI were(38.033±5.605)%, (33.000±6.192)%, (28.767±7.045)%, (22.200±5.517)%, (17.700±4.836)%, (11.900±2.771)%, respectively. The JOA scores of the McKenzie combined with 3D printing group before treatment and at 1, 3, 6, 9, and 12 months post-treatment were(8.900±2.074), (13.133±2.330), (15.700±3.583), (20.400±3.480), (22.267±3.084), (24.833±2.640), respectively. In the McKenzie group, the corresponding scores were(9.200±2.091), (12.267±2.406), (15.333±3.198), (18.467±2.240), (20.133±2.751), (22.467±2.849), respectively. Before the initiation of treatment, no statistically significant differences were observed in the VAS, ODI, and JOA scores between two groups (P>0.05). At 3, 6, 9, and 12 months post-treatment, the VAS in the McKenzie combined with 3D printing group was significantly lower than that in the McKenzie group, and the difference was statistically significant (P<0.05). The comparison of ODI between two groups at 1, 3, 6, 9, and 12 months post-treatment revealed statistically significant differences (P<0.05). At 6, 9, and 12 months post-treatment, the JOA score in the McKenzie combined with 3D printing group was significantly higher than that in the McKenzie-only group, and the difference was statistically significant (P<0.05). CONCLUSION The combination of 3D printed functional spinal external fixation brace with McKenzie therapy can significantly improve and maintain lumbar function in patients with LDH.

OBJECTIVE: The relationship between fish consumption and stroke is inconsistent, and it is uncertain whether this association varies across predicted stroke risks. METHODS: A cohort study comprising 95,800 participants from the Prediction for Atherosclerotic Cardiovascular Disease Risk in China project was conducted. A standardized questionnaire was used to collect data on fish consumption. Participants were stratified into low- and moderate-to-high-risk categories based on their 10-year stroke risk prediction scores. Hazard ratios ( HRs) and 95% confidence intervals ( CIs) were estimated using Cox proportional hazard models and additive interaction by relative excess risk due to interaction (RERI), attributable proportion (AP), and synergy index (SI). RESULTS: During 703,869 person-years of follow-up, 2,773 incident stroke events were identified. Higher fish consumption was associated with a lower risk of stroke, particularly among moderate-to-high-risk individuals ( HR = 0.53, 95% CI: 0.47-0.60) than among low-risk individuals ( HR = 0.64, 95% CI: 0.49-0.85). A significant additive interaction between fish consumption and predicted stroke risk was observed (RERI = 4.08, 95% CI: 2.80-5.36; SI = 1.64, 95% CI: 1.42-1.89; AP = 0.36, 95% CI: 0.28-0.43). CONCLUSION Higher fish consumption was associated with a lower risk of stroke, and this beneficial association was more pronounced in individuals with moderate-to-high stroke risk.

Objective:To analyze the epidemic characteristics of reported tuberculosis incidence in Kashgar from 2015 to 2022, and use the seasonal autoregressive integrated moving average (SARIMA) model to predict the incidence, providing references for the local control of pulmonary tuberculosis.Methods:The reported incidence data of tuberculosis in the Kashgar area of Xinjiang from January 2015 to August 2023 were collected through the"Infectious Disease Monitoring System", a subsystem of the "Chinese Disease Prevention and Control Information System". The epidemic characteristics of reported incidence in this area from 2015 to 2022 were analyzed. Two SARIMA models of monthly reported incidence number and rate were established. The prediction performance of the two models was evaluated using the reported incidence data of tuberculosis from January 2023 to August 2023. The χ2 test was used to analyze population characteristics, and the Cochran-Armitage trend test was used to analyze annual incidence. Results:From 2015 to 2022, 133 972 cases of pulmonary tuberculosis were reported in Kashgar, with a yearly reported incidence rate of 383.64/100 000, showing a rising trend ( TCA=77.03, P<0.001) and then a declining trend ( TCA=176.16, P<0.001). The proportion of pathogenic positive pulmonary tuberculosis had increased yearly ( TCA=132.66, P<0.001). The reported onset time was concentrated from January to June each year, with a peak in April. Yengisar County, Zepu County and Yopurga County had the highest reported incidence rate in Kashgar. The sex ratio of men to women was 1.03∶1, and the reported incidence rate of men was higher than that of women ( χ2=27.04, P<0.001). The reported incidence rate of the group aged 60 years and older was the highest. The patient′s occupation was mainly farmers (84.99%). The average relative errors of the SARIMA ( 1, 1, 2) ( 0, 1, 1) 12 model and SARIMA ( 0, 1, 1)( 0, 1, 1) 12 model in predicting the reported monthly incidence number and rate were 11.67% and -9.81%, respectively. Both models had good prediction accuracy (MAPE=33.55%, MAPE=38.22%). Conclusion:The average reported incidence rate of pulmonary tuberculosis in the Kashgar area shows a rising trend first and then a declining trend. The patients are mainly men and farmers, and attention should be paid to the prevention and control of tuberculosis among the elderly in winter and spring. The SARIMA ( 1, 1, 2) ( 0, 1, 1) 12 model and SARIMA ( 0, 1, 1)( 0, 1, 1) 12 model can fit the trend of reported tuberculosis incidence in the Kashgar area well and have good predictive performance.

Objective To explore the relationship between serum ferritin levels and body fat distribution in patients with type 2 diabetes mellitus(T2DM).Methods A retrospective analysis was conducted on 151 patients with T2DM who were hospitalized in the Department of Endocrinology of the First Hospital of Lanzhou University from June to November 2020,and all the patients were divided into high serum ferritin(n=50)and normal serum ferritin(n=101)groups according to their serum ferritin levels.The visceral fat area(VFA),subcutaneous fat area(SFA),liver fat,height,weight and waist circumference(WC)were measured,as well as blood glucose,lipid indexes,body mass index(BMI)and visceral adiposity index(VAI)were also calculated.t-test or nonparametric test was used to compare the differences between the two groups,and the relationship between serum ferritin levels and body fat distribution was analyzed by Pearson or Spearman correlation analysis,multiple linear regression and logistic regression.Results The VAI and WC were significantly higher in high serum ferritin group[3.13(2.16,4.58)and(96.66±7.78)cm]than in normal serum ferritin group[2.66(1.66,3.81)and(91.96±9.75)cm,P<0.05].The prevalence of central obesity and dyslipidemia was higher in high serum ferritin group(88.0%and 90.0%)than in normal serum ferritin group(68.3%and 75.2%);and the composition ratios of poor glycemic control and insulin resistance(96.0%and 62.0%)were also higher than in normal serum ferritin group(78.2%and 40.6%)(P<0.05),there were no statistically significant differences in BMI,VFA,and SFA levels,as well as antidiabetic drug use and chronic complications of diabetes mellitus between the two groups(P>0.05).Serum ferritin levels in T2DM patients were positively correlated with VAI,WC,triglyceride(TG),fasting blood glucose(FPG),HbA1c,dyslipidemia and serum creatinine(r=0.171,0.207,0.187,0.243,0.270,0.162,0.162;P<0.05),and negatively correlated with age,sex and diabetes course(r=-0.191,-0.434,-0.352;P<0.05).Multivariate linear regression analysis showed that in male T2DM patients,duration of diabetes and FPG were risk factors for increased levels of serum ferritin.However,WC and VAI did not significantly affect serum ferritin levels.In female patients with T2DM,the course of diabetes,TG and VAI were the factors influencing serum ferritin(P<0.05).Conclusion Dyslipidemia and visceral fat accumulation are risk factors for elevated serum ferritin levels in female T 2DM patients.

Molecular imprinting is a biomimetic technique that simulates the specific recognition of biological macromolecules such as antibody. Based on molecular imprinting and high-specificity affinity analysis,the biomimetic imprinting affinity analysis (BIA) possesses many advantages such as high sensitivity,strong tolerance,good specificity and low cost,and thus,it has shown excellent prospects in food safety detection,pharmaceutical analysis and environmental pollution monitoring. In this review,the construction methods of recognition interfaces for BIA were summarized,including bulk polymerization,electro-polymerization and surface molecular imprinting. The application of molecularly imprinted polymers in different analysis methods,such as radiolabeled affinity analysis,enzyme-labeled affinity analysis,fluorescence-labeled affinity analysis,chemiluminescence affinity analysis and electrochemical immunosensor was mainly discussed. Furthermore,the challenges and future development trends of BIA in practical application were elucidated. This review might provide new reference ideas and technical supports for the further development of BIA technique.

Objective To investigate the regulatory effect of Jianpi Huayu Prescription(Ginseng Radix et Rhizoma,Poria,Atractylodis Macrocephalae Rhizoma,Salviae Miltiorrhizae Radix et Rhizoma,etc.)on epithelial-mesenchymal transition(EMT)and angiogenesis of hepatocellular carcinoma through TGF-β1/Smad7 pathway.Methods(1)Hep3B tumor-bearing mouse model was established by BALB/C-nu nude mice.The mice were randomly divided into control group and Jianpi Huayu Prescription low-,medium-and high-dose groups(3.844,7.689,15.378 g·kg-1·d-1),with five mice in each group.Intragastric administration was performed once a day for 21 days.(2)Hep3B cells were divided into blank group,model group(10 ng·mL-1 TGF-β1),low-concentration group(10 ng·mL-1 TGF-β1+4 mg·mL-1 Jianpi Huayu Prescription),and high-concentration group(10 ng·mL-1 TGF-β1+6 mg·mL-1 Jianpi Huayu Prescription).After 48 hours of TGF-β1 induction,the cells were replaced with the corresponding concentration of Jianpi Huayu Prescription complete culture medium(0,4,6 mg·mL-1)and cultured for 24 hours.(3)HUVEC cells were divided into normal group,model group,Chinese medicine group,model plus Chinese medicine group.The cells in the normal group were cultured with conditioned medium without TGF-β1;the cells in the model group were cultured with conditioned medium containing TGF-β1.The cells in the Chinese medicine group were cultured in conditioned medium containing 4 mg·mL-1 Jianpi Huayu Prescription without TGF-β 1.The cells in the model plus Chinese medicine group were cultured with conditioned medium containing 4 mg·mL-1 Jianpi Huayu Prescription and TGF-β1.After 24 hours of continuous culture,the cells were collected for subsequent experiments.(4)The tumor mass index and tumor inhibition rate of subcutaneous transplantation tumor of Hep3B tumor-bearing nude mice were calculated.The expression of CD31 in subcutaneous xenografts of tumor-bearing nude mice was detected by immunofluorescence.The microvessel density of subcutaneous transplanted tumor in nude mice was detected by immunohistochemistry.The migration ability of Hep3B cells was detected by cell scratch test.Transwell assay was used to detect the invasion ability of Hep3B/HUVEC cells.The tube formation ability of HUVEC cells was detected.The expression levels of related proteins in subcutaneous transplanted tumors,Hep3B and HUVEC cells of tumor-bearing nude mice were detected by Western Blot.Results(1)Compared with the control group,the weight and tumor mass index of subcutaneous transplanted tumor in nude mice in the medium-and high-dose groups of Jianpi Huayu Prescription were significantly decreased(P＜0.01).The expression of CD31 and microvessel density in subcutaneous transplanted tumors of nude mice in low-,medium-and high-dose groups were significantly decreased(P＜0.05,P＜0.01),the protein expressions of VE-cadherin,EphA2 and N-cadherin were significantly down-regulated(P＜0.05,P＜0.01),and the protein expressions of E-cadherin and Smad7 was significantly up-regulated(P＜0.01).(2)Compared with the blank group,the relative migration rate of Hep3B cells in the model group was significantly increased(P＜0.05),and the number of invasive cells was significantly increased(P＜0.01).The protein expressions of Vimentin and N-cadherin were significantly up-regulated(P＜0.01),and the protein expressions of E-cadherin and Smad7 was significantly down-regulated(P＜0.01).Compared with the model group,the relative migration rate of Hep3B cells in the low-and high-concentration groups of Jianpi Huayu Prescription was significantly decreased(P＜0.01),and the number of invasive cells was significantly decreased(P＜0.01).The protein expressions of Vimentin and N-cadherin was significantly down-regulated(P＜0.01),and the protein expressions of E-cadherin and Smad7 were significantly up-regulated(P＜0.01).(3)Compared with the normal group,the number of tubular branching points formed by HUVEC cells in the model group was significantly increased(P＜0.01),the length of tubular branching was significantly increased(P＜0.01),and the number of invasive cells was significantly increased(P＜0.01).The protein expressions of VE-cadherin and EphA2 were significantly up-regulated(P＜0.01),and the protein expression of Smad7 was significantly down-regulated(P＜0.01).Compared with the model group,the number of tubular branching points formed by HUVEC cells in the model plus Chinese medicine group was significantly reduced(P＜0.01),the length of tubular branching was significantly shortened(P＜0.01),and the number of invasive cells was significantly reduced(P＜0.01).The protein expressions of VE-cadherin and EphA2 were significantly down-regulated(P＜0.01),and the protein expression of Smad7 was significantly up-regulated(P＜0.01).Conclusion Jianpi Huayu Prescription can significantly inhibit the growth,invasion and migration of hepatocellular carcinoma,which may be related to the regulation of EMT and angiogenesis mediated by TGF-β1/Smad7 pathway.

Background/Aims: Metabolic dysfunction-associated steatotic liver disease (MASLD) has become an increasingly important health challenge, with a substantial rise linked to changing lifestyles and global obesity. Ursolic acid, a natural pentacyclic triterpenoid, has been explored for its potential therapeutic effects. Given its multifunctional bioactive properties, this research further revealed the pharmacological mechanisms of ursolic acid on MASLD. Methods: Drug target chips and bioinformatics analysis were combined in this study to explore the potential therapeutic effects of ursolic acid on MASLD. Molecular docking simulations, surface plasmon resonance analyses, pull-down experiments, and co-immunoprecipitation assays were used to verify the direct interactions. Gene knockdown mice were generated, and high-fat diets were used to validate drug efficacy. Furthermore, initial CD4+ T cells were isolated and stimulated to demonstrate our findings. Results: In this study, the multifunctional extracellular matrix phosphorylated glycoprotein secreted phosphoprotein 1 (SPP1) was investigated, highlighting its capability to induce Th17 cell differentiation, amplifying inflammatory cascades, and subsequently promoting the evolution of MASLD. In addition, this study revealed that in addition to the canonical TGF-β/IL-6 cytokine pathway, SPP1 can directly interact with ITGB1 and CD44, orchestrating Th17 cell differentiation via their joint downstream ERK signaling pathway. Remarkably, ursolic acid intervention notably suppressed the protein activity of SPP1, suggesting a promising avenue for ameliorating the immunoinflammatory trajectory in MASLD progression. Conclusions Ursolic acid could improve immune inflammation in MASLD by modulating SPP1-mediated Th17 cell differentiation via the ERK signaling pathway, which is orchestrated jointly by ITGB1 and CD44, emerging as a linchpin in this molecular cascade.

Cardiac-resident macrophages (CRMs) play important roles in homeostasis, cardiac function, and remodeling. Although CRMs play critical roles in cardiac regeneration of neonatal mice, their roles are yet to be fully elucidated. Therefore, this study aimed to investigate the dynamic changes of CRMs during cardiac ontogeny and analyze the phenotypic and functional properties of CRMs in the promotion of cardiac regeneration. During mouse cardiac ontogeny, four CRM subsets exist successively: CX₃CR1⁺CCR2^-Ly6C^-MHCII^- (MP1), CX₃CR1^lowCCR2^lowLy6C^-MHCII^- (MP2), CX₃CR1^-CCR2⁺Ly6C⁺MHCII^- (MP3), and CX₃CR1⁺CCR2^-Ly6C^-MHCII⁺ (MP4). MP1 cluster has different derivations (yolk sac, fetal liver, and bone marrow) and multiple functions population. Embryonic and neonatal-derived-MP1 directly promoted cardiomyocyte proliferation through Jagged-1-Notch1 axis and significantly ameliorated cardiac injury following myocardial infarction. MP2/3 subsets could survive throughout adulthood. MP4, the main population in adult mouse hearts, contributed to inflammation. During ontogeny, MP1 can convert into MP4 triggered by changes in the cellular redox state. These findings delineate the evolutionary dynamics of CRMs under physiological conditions and found direct evidence that embryonic and neonatal-derived CRMs regulate cardiomyocyte proliferation. Our findings also shed light on cardiac repair following injury.

Neuropathic pain is a chronic disease that severely afflicts the life and emotional status of patients, but currently available treatments are often ineffective. Novel therapeutic targets for the alleviation of neuropathic pain are urgently needed. Rhodojaponin VI, a grayanotoxin from Rhododendron molle, showed remarkable antinociceptive efficacy in models of neuropathic pain, but its biotargets and mechanisms are unknown. Given the reversible action of rhodojaponin VI and the narrow range over which its structure can be modified, we perforwmed thermal proteome profiling of the rat dorsal root ganglion to determine the protein target of rhodojaponin VI. N-Ethylmaleimide-sensitive fusion (NSF) was confirmed as the key target of rhodojaponin VI through biological and biophysical experiments. Functional validation showed for the first time that NSF facilitated trafficking of the Cav2.2 channel to induce an increase in Ca²⁺ current intensity, whereas rhodojaponin VI reversed the effects of NSF. In conclusion, rhodojaponin VI represents a unique class of analgesic natural products targeting Cav2.2 channels via NSF.
