OBJECTIVE:
To elucidate how spinal manipulative therapy (SMT) exerts its analgesic effects through regulating brain function in lumbar disc herniation (LDH) patients by utilizing resting-state functional magnetic resonance imaging (rs-fMRI).
METHODS:
From September 2021 to September 2023, we enrolled LDH patients (LDH group, n=31) and age- and sex-matched healthy controls (HCs, n=28). LDH group underwent rs-fMRI at 2 distinct time points (TPs): prior to the initiation of SMT (TP1) and subsequent to the completion of the SMT sessions (TP2). SMT was administered once every other day for 30 min per session, totally 14 treatment sessions over a span of 4 weeks. HCs did not receive SMT treatment and underwent only one fMRI scan. Additionally, participants in LDH group completed clinical questionnaires on pain using the Visual Analog Scale (VAS) and the Japanese Orthopedic Association (JOA) score, whereas HCs did not undergo clinical scale assessments. The effects on the brain were jointly characterized using the amplitude of low-frequency fluctuations (ALFF) and regional homogeneity (ReHo). Correlation analyses were conducted between specific brain regions and clinical scales.
RESULTS:
Following SMT treatment, pain symptoms in LDH patients were notably alleviated and accompanied by evident activation of effects in the brain. In comparison to TP1, TP2 exhibited the most significant increase in ALFF values for Temporal_Sup_R and the most notable decrease in ALFF values for Paracentral_Lobule_L (voxelwise P<0.005; clusters >30; FDR correction). Additionally, the most substantial enhancement in ReHo values was observed for the Cuneus_R, while the most prominent reduction was noted for the Olfactory_R (voxelwise P<0.005; clusters >30; FDR correction). Moreover, a comparative analysis revealed that, in contrast to HCs, LDH patients at TP1 exhibited the most significant increase in ALFF values for Temporal_Pole_Sup_L and the most notable decrease in ALFF values for Frontal_Mid_L (voxelwise P<0.005; clusters >30; FDR correction). Furthermore, the most significant enhancement in ReHo values was observed for Postcentral_L, while the most prominent reduction was identified for ParaHippocampal_L (voxelwise P<0.005; clusters >30; FDR correction). Notably, correlation analysis with clinical scales revealed a robust positive correlation between the Cuneus_R score and the rate of change in the VAS score (r=0.9333, P<0.0001).
CONCLUSIONS
Long-term chronic lower back pain in patients with LDH manifests significant activation of the "AUN-DMN-S1-SAN" neural circuitry. The visual network, represented by the Cuneus_R, is highly likely to be a key brain network in which the analgesic efficacy of SMT becomes effective in treating LDH patients.

OBJECTIVE:
To investigate the antidepressant effects of Xiaoyao Pill (XYP) by exploring its interactions with gut microbiota and tryptophan metabolism.
METHODS:
Utilizing network pharmacology, the functional substance groups, key targets, and pathways of XYP in the treatment of depression were identified. The chronic unpredictable mild stress (CUMS) protocol was implemented in male Sprague-Dawley rats to establish depression model. Thirty rats were randomly divided into 3 groups according to their body weight (10 for each): control, CUMS and XYP groups (1.8 g/kg). After 28-day interventions, behavioral phenotyping including sucrose preference test (SPT) and open field test (OFT) were performed. Biochemical validation encompassed enzyme-linked immunosorbent assay for serum cortisol, hematoxylin-eosin histopathology, and immunohistochemistry. Liquid chromatography-mass spectrometry was utilized to profile serum metabolites, while fecal samples underwent metagenomic sequencing for gut microbiota characterization.
RESULTS:
Network pharmacology studies predicted that key components can protect the nervous system by regulating inflammatory pathways through the blood-brain barrier. SPT and OFT showed that XYP treatment significantly ameliorated depressive-like behaviors (all P<0.05). XYP treatment also restored hippocampal neuronal density, increased serum neurotransmitter levels of neurotransmitters such as 5-hydroxytryptamine and vasoactive intestinal peptide, and while suppressing inflammatory markers such as tumor necrosis factor-alpha, interleukin-1 beta (IL-1 β), and IL-6 (all P<0.05). Metagenomics revealed significant restructuring of gut microbiota, notably the regulation of Parabacteroides distasonis (P<0.05). Non-targeted metabolomics analysis showed that the level of metabolites in the tryptophan and kynurenine pathway significantly changed (variable importance in the projection >1, P<0.05), and the change of metabolic flux was significantly correlated with behavioral improvement (P<0.05).
CONCLUSIONS
XYP exerts antidepressant effects by increasing neurotransmitter levels, reducing inflammatory makers and modulating Parabacteroides distasonis. Through further exploration of metabolomics, we found that XYP may play a protective role in depression by regulating tryptophan metabolism.

OBJECTIVE:
To investigate the efficacy and safety of oblique lateral interbody fusion(OLIF) channel technique combined with pedicle screw internal fixation in the treatment of single-segment lumbar intervertebral space/vertebral body infection.
METHODS:
A retrospective analysis was conducted on 23 patients who underwent surgical treatment for lumbar infection from January 2021 to December 2022. The patients were divided into the OLIF channel group and the traditional open surgery group according to the surgical methods. There were 16 cases in the OLIF channel group, including 9 males and 7 females, with an average age of (68.5±12.1) years old;there were 7 cases in the traditional open surgery group, including 4 males and 3 females, with an average age of (75.0±3.2) years old. The operation time, intraoperative blood loss, hospital stay, incision length, visual analogue scale(VAS), activities of daily living (ADL) score, Oswestry disability index (ODI), erythrocyte sedimentation rate(ESR), C-reactive protein(CRP) before and 1 week and 3 months after the operation, and the intervertebral fusion status on the last follow-up CT were compared between the two groups.
RESULTS:
Compared with the open surgery group, the OLIF channel group had shorter operation time (209.87±31.5) min vs. (246.0±42.7) min, less intraoperative blood loss (225.625±91.1) ml vs. (364.2±74.8) ml, and shorter incision length (6.1±1.2) vs. (14.0±1.4) cm, and the differences were statistically significant(P<0.05). Before and 1 week and 3 months after the operation, the lumbar VAS in the OLIF group were (6.3±0.6), (2.8±0.7), (1.1±0.5), and those in the traditional open surgery group were (6.4±0.6), (3.4±0.5), (1.2±0.3);the ADL scores in the OLIF group were (45.0±4.5), (60.3±4.3), (94.1±4.2), and those in the open group were (46.4±5.6), (60.7±4.5), (92.9±4.9); the ODI scores in the OLIF group were (86.3±2.9)%, (69.5±4.1)%, (23.0±3.2)%, and those in the open group were (87.3±3.8)%, (69.8±4.2)%, (23.8±3.6)%, all of which showed significant improvement(P<0.05). Three months after the operation, CRP, PCT, and ESR were significantly lower than those before the operation, and CRP and PCT returned to normal, while ESR was still slightly elevated in some patients. The last follow-up CT showed that continuous trabecular bone formation was observed between the upper and lower endplates of the surgical segments in all patients, and the fusion time was (8.7±4.5) months.
CONCLUSION
The OLIF channel technique combined with posterior internal fixation is a minimally invasive and effective treatment method, which can effectively control infection, relieve pain, and improve the quality of life of patients. Compared with traditional open surgery, it has the advantages of minimally invasive, shorter operation time, and less intraoperative blood loss.

OBJECTIVE:
To assess health equity in the Yangtze River region to improve understanding of the correlation between hand, foot, and mouth disease (HFMD) and socioeconomic factors.
METHODS:
From 2014-2016, data on HFMD incidence, population statistics, economic indicators, and meteorology from 26 cities along the Yangtze River were analyzed. A multi-city random-effects meta-analysis was performed to study the relationship between temperature and HFMD transmission, and health equity was assessed with respect to socio-economic impact.
RESULTS:
Over the study period, 919,458 HFMD cases were reported, with Shanghai (162,303) having the highest incidence and Tongling (5,513) having the lowest. Males were more commonly affected (male-to-female ratio, 1.49:1). The exposure-response relationship had an M-shaped curve, with two HFMD peaks occurring at 4 °C and 26 °C. The relative risk had two peaks at 1.30 °C (1.834, 95% CI: 1.204-2.794) and 31.4 °C (1.143, 95% CI: 0.901-1.451), forming an M shape, with the first peak higher than the second. The most significant impact of temperature on HFMD was observed between -2 °C and 18.1 °C. The concentration index (0.2463) indicated moderate concentration differences, whereas the Theil index (0.0418) showed low inequality in distribution.
CONCLUSION
The incidence of HFMD varied across cities, particularly with changes in temperature. Economically prosperous areas showed higher risks, indicating disparities. Targeted interventions in these areas are crucial for mitigating the risk of HFMD.

Objective To explore and verify the active components of Dachengqi decoction in regulating autophagy and its mechanism of protecting the intestinal mucosal barrier through network pharmacology and animal experiments.Methods The chemical components and autophagy-related target points of Dachengqi decoction were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database Analysis Platform(TCMSP)and GeneCards databases.The intersection of the drug target points and disease target points was taken and analyzed.The Cytoscape 3.10.2 software's Network Analyzer tool was used to analyze the drug components and target points,and the core target points were screened out to construct a traditional Chinese medicine compound regulatory network.The drug active component target point-disease network model and protein-protein interaction(PPI)network were visualized.Then,30 C57BL/6J mice were randomly divided into the Dachengqi decoction group,the intestinal infection group,and the control group,with 10 mice in each group.The intestinal infection group was given 200 μL/d of Klebsiella pneumoniae strain by gavage for 5 consecutive days,with a colony count of 109 CFU/mL,to create an intestinal infection model.The control group was given 200 μL/d of sterile normal saline by gavage.The Dachengqi decoction group(drug composition:Rhubarb 12 g,Aurantii Fructus 12 g,Magnolia Officinalis 24 g,Mirabilite 9 g,the drugs were dissolved in boiling distilled water to make a 1 kg/L solution)was given by gavage at a dose of 8 g·kg-1·d-1 for 3 consecutive days,and then given Klebsiella pneumoniae by gavage for 5 consecutive days on the 4th day.Detection indicators and methods:after the experiment,the mice were sacrificed and the terminal ileum tissues were collected.The tissues were stained with hematoxylin-eosin(HE),and the pathological changes of the intestinal mucosa were observed under a light microscope;immunofluorescence staining was used to observe the positive expressions of junction proteins ZO-1,Claudin-2,light chain 3-Ⅱ(LC3-Ⅱ),and Beclin-1 and the intestinal mucosal autophagy;the mRNA expression levels of autophagy genes were determined by polymerase chain reaction(PCR).Results The intersection of the obtained drug targets and disease targets yielded 111 potential autophagy-related targets for drug treatment of diseases.Key targets included β2-adrenergic receptor(ADRB2),heme oxygenase-1(HO-1),etc.,and the signaling pathways involved included AMP-activated protein kinase(AMPK)pathway,mammalian target of rapamycin(mTOR)pathway,etc.Animal experiments confirmed that the intestinal mucosal barrier function in the Dachengqi decoction group was better than that in the intestinal infection group,and the positive expression of microtubule-associated protein 1 lingt chain 3-Ⅱ(LC3-Ⅱ)and autophagy gene Beclin1 was significantly higher than that in the intestinal infection group.Transcriptome sequencing results showed that the key genes associated with autophagy and oxidative stress included ADRB2,HO-1,etc.The mRNA expression levels of ADRB2 and HO-1 in the Dachengqi decoction group were significantly higher than those in the intestinal infection group[HO-1 mRNA expression(FPKM):11.20±0.80 vs.6.63±0.53,ADRB2 mRNA expression(FPKM):6.98±0.54 vs.3.98±0.32,both P<0.01],verifying some of the predictions from network pharmacology.Conclusions Dachengqi decoction regulates autophagy through multiple components,multiple targets and multiple pathways,protecting the intestinal mucosal barrier function and reducing the translocation of intestinal microbiota.This lays a certain foundation for further in-depth research on the mechanism of reducing intestinal bacterial translocation by Dachengqi decoction.

BACKGROUND:Degenerative scoliosis is defined as a condition that occurs in adulthood with a coronal cobb angle of the spine>10° accompanied by sagittal deformity and rotational subluxation,which often produces symptoms of spinal cord and nerve compression,such as lumbar pain,lower limb pain,numbness,weakness,and neurogenic claudication.The finite element method is a mechanical analysis technique for computer modelling,which can be used for spinal mechanics research by building digital models that can realistically restore the human spine model and design modifications. OBJECTIVE:To review the application of finite element method in the etiology and treatment of degenerative scoliosis. METHODS:The literature databases CNKI,PubMed,and Web of Science were searched for articles on the application of finite element method in degenerative scoliosis published before October 2023.Search terms were"finite element analysis,biomechanics,stress analysis,degenerative scoliosis,adult spinal deformity"in Chinese and English.Fifty-four papers were finally included. RESULTS AND CONCLUSION:(1)The biomechanical findings from the degenerative scoliosis model constructed using the finite element method were identical to those from the in vivo experimental studies,which proves that the finite element method has a high practical value in degenerative scoliosis.(2)The study of the etiology and treatment of degenerative scoliosis by the finite element method is conducive to the prevention of the occurrence of the scoliosis,slowing down the progress of the scoliosis,the development of a more appropriate treatment plan,the reduction of complications,and the promotion of the patients'surgical operation.(3)The finite element method has gradually evolved from a single bony structure to the inclusion of soft tissues such as muscle ligaments,and the small sample content is increasingly unable to meet the research needs.(4)The finite element method has much room for exploration in degenerative scoliosis.

Aim Mouse model of myocardial hypertro-phy was established via intraperitoneal injection of iso-proterenol(ISO)in mice.This approach allows for an in-depth investigation into the pharmacological effects and mechanisms of action of emodin,offering novel in-sights and directions for the improvement of myocardial hypertrophy.Methods The mice were randomly di-vided into the following groups:control group(CON),emodin group(EMO),MAPK activator control group(EMO+Ani),model group(ISO),treatment group(ISO+EMO),and activator intervention group(ISO+EMO+Ani).After treatment with emodin and inter-vention with MAPK activator,the heart weight ratio and cardiac size of each group were observed.Hematoxy-lin-eosin(HE)staining was used to observe the patho-logical changes in cardiac tissue,and kits were utilized to measure the levels of GSH,LDH,and MDA in the serum.Western blot was employed to detect the protein expression levels of inflammatory and oxidative factors,as well as p-p38,p-ERK,p38,and ERK in cardiac tis-sue.Results Emodin can significantly inhibit the production of myocardial inflammatory and oxidative factors induced by ISO,thereby effectively alleviating the degree of myocardial hypertrophy and fibrosis.Af-ter the p38/ERK signaling pathway was specifically ac-tivated by farnesol,the improvement effect of emodin on myocardial hypertrophy was weakened.Further comparison revealed that,compared with the myocardi-al hypertrophy pathological model group,the pathologi-cal protein expression levels in the farnesol-treated group showed no significant difference,and were even higher in some indicators.Conclusion Emodin can effectively inhibit the release of inflammatory factors and improve the state of oxidative stress by modulating the p38/ERK signaling pathway,thereby exerting an ameliorative effect on myocardial hypertrophy.

Objective:To explore the predictive role of dynamic changes in serum Golgi protein 73 (GP73) and its inflammatory influencing factors on the reversal of hepatitis B virus-related liver fibrosis.Methods:Two hundred and seventy-eight patients with hepatitis B virus-related liver fibrosis who received entecavir or combined Fuzheng Huayu tablets treatment and completed two liver biopsies (biopsy) in Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from September 2014 to July 2019 were selected. The correlation between serum GP73 level and fibrosis stage (Ishak) and inflammation grade (HAI) was analyzed. The patients were divided into a fibrosis reversal group (Ishak decreased≥1 point) and a non-reversal group (Ishak score remained unchanged or increased), and an inflammation improvement group (ΔHAI≤-2) and a non-improvement group (ΔHAI>-2) according to the pathological changes of liver tissue before and after treatment. The cross-sectional value of GP73, its change value (ΔGP73), and the role of inflammatory influencing factors on the liver before and after treatment were evaluated for their predictive efficacy regarding liver fibrosis regression. The receiver operating characteristic curve was used to explore the predictive value of serum ΔGP73 combined with liver stiffness change value (ΔLSM) for the reversal of hepatitis B virus-related liver fibrosis. One-way analysis of variance was used to compare the data between the groups of quantitative data, and a paired t-test or rank sum test was used for the data before and after treatment. The χ2 test was used to compare the differences between the groups of enumeration data. Spearman and Pearson correlation methods were used for correlation analysis. Results:The serum GP73 level was higher in the cirrhosis group than that in the group without significant fibrosis ( P<0.01). The GP73 level was higher in patients with moderate and severe inflammation than that in the mild group ( P<0.05). Pre-treatment serum GP73 was positively correlated with fibrosis stage ( r=0.248), inflammation grade ( r=0.318), and alanine aminotransferase level ( r=0.203) ( P<0.01). The area under the receiver operating characteristic curve (AUROC) for the predictive ability of post-treatment GP73 levels in the fibrosis reversal was 0.633 (95% CI: 0.573-0.689, sensitivity 62.68%, and specificity 59.56%). The decrease in ΔGP73 was significantly higher in the liver fibrosis reversal group ( n=142) than that in the non-reversal group ( n=136) [-39.22(-85.08,-14.31) ng/mL vs. -30.06(-61.29,-5.84) ng/mL, P<0.01]. ΔGP73 was also associated with liver inflammation changes (AUROC=0.634, 95% CI: 0.574-0.690, sensitivity of 51.64%, specificity of 69.87%). Additionally, the predictive effectiveness of GP73 for fibrosis reversal improved after normalization of serum ALT (AUROC: 0.651 vs. 0.522 at baseline). ΔGP73 combined with ΔLSM had improved the AUROC predictive effectiveness from single indicators of 0.609 (ΔGP73) and 0.656 (ΔLSM) to 0.800 (95% CI: 0.662-0.899), with specificity increasing from 72.22% to 86.11%. Conclusion:Serum GP73 level is positively correlated with the degree of liver fibrosis and inflammation. Serum GP73 levels and ΔGP73 can predict the reversal of fibrosis, with liver inflammation being an important influencing factor following treatment. ΔGP73 combined with ΔLSM can significantly optimize the evaluation efficiency of liver fibrosis reversal.
