Atherosclerosis （AS） is the main pathological basis of cardiovascular diseases and seriously threatens human quality of life. Its prevention and treatment urgently need breakthroughs. The inflammatory response， which runs through the physiological and pathological evolution process of AS， is one of the important mechanisms for AS occurrence. Currently， the treatment methods for AS in Western medicine are relatively mature. However， they have adverse reactions such as abnormal liver and kidney function， drug tolerance， target vessel restenosis， and stent thrombosis， which remain the key bottleneck restricting clinical efficacy. Traditional Chinese medicine （TCM）， characterized by multiple components， multiple targets， and multi-pathway synergy， shows unique clinical application potential and efficacy advantages in the intervention of AS. This article reviewed the research progress of TCM in intervening in AS by regulating inflammatory-related signaling pathways， such as nuclear factor-κB （NF-κB）， Toll-like receptors （TLRs）， mitogen-activated protein kinase （MAPK）， and Janus kinase/signal transducer and activator of transcription （JAK/STAT）， in the past five years. It summarized the combined mechanism of action of TCM monomers， TCM pairs， and compound preparations in inhibiting the inflammatory cascade reaction through multiple targets， regulating lipid metabolism disorders， and improving vascular endothelial dysfunction and the imbalance of the microenvironment. It deepened the research on the molecular mechanism of TCM in anti-AS， so as to provide a scientific basis for the clinical transformation application and related theoretical research of TCM in anti-AS.

Background and aims The mechanism of cholestatic liver injury (CLI) is unclear, and effective therapies are lacking. While peroxisome proliferator-activated receptor alpha (PPARα) agonists show potential hepatoprotective effect and pyroptosis is implicated in hepatocellular damage, how PPARα activation mitigates lithocholic acid (LCA)-induced pyroptosis remains unknown. Methods The hepatoprotective effect of PPARα agonists was evaluated in a mouse model of intrahepatic cholestasis induced by LCA. Liver injury was assessed via serum biochemistry, hematoxylin and eosin and TUNEL staining, and electron microscopy. Pyroptosis pathways were analyzed using real-time quantitative polymerase chain reaction, Western blot, and co-immunoprecipitation. Results Combined morphological, histopathological, and biochemical analyses confirmed that PPARα activation protects against CLI. Compared with LCA treatment alone, PPARα activation significantly attenuated the elevation of serum lactate dehydrogenase (LDH), the increased TUNEL-positive cells, and the formation of hepatocyte membrane pores. Mechanistically, PPARα activation suppressed both NOD-like receptor protein 3 (NLRP3) inflammasome-mediated pyroptosis and apoptosis protease-activating factor-1 (APAF-1)/CASPASE-3/GSDME-mediated pyroptosis. Furthermore, PPARα agonist pretreatment inhibited activation of the nuclear factor-kappa B (NF-κB) and forkhead box O1 (FOXO1) signaling pathways. Conclusions PPARα protects against LCA-induced CLI by inhibiting both NLRP3 inflammasome-mediated pyroptosis associated with NF-κB and APAF-1/CASPASE-3/GSDME-mediated pyroptosis associated with the FOXO1 signaling pathway.

Objective To investigate the association between single nucleotide polymorphisms (SNPs) in the nicotinamide adenine dinucleotide phosphate-oxidase (NOX) 2 and NOX4 genes and susceptibility to noise-induced hearing loss (NIHL). Methods A total of 439 noise-exposed workers were recruited using a convenience sampling method. Based on pure-tone air conduction hearing threshold tests, participants were categorized into normal hearing, mild hearing loss, and moderate hearing loss groups, with 147, 154, 138 individuals, respectively. Peripheral venous blood samples of the workers were collected for DNA extraction. Genotyping of nine SNPs loci in NOX2 and NOX4 genes was performed using multiplex polymerase chain reaction, single-base extension, and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Results A total of seven of the nine SNPs loci conformed to Hardy-Weinberg equilibrium among the workers in the normal hearing group (all P>0.05). There was no significant difference in the genotype distribution or allele frequencies for these seven SNPs loci among workers in these three groups (all P>0.05). Ordinal logistic regression analysis showed that, after adjusting for confounders including age, sex, cumulative noise exposure, smoking, alcohol consumption, and earplug use, individuals carrying the GG genotype at rs200522762 had a lower risk of NIHL compared with those carrying the TT genotype under the codominant model (P<0.05). In the recessive model, individuals carrying the GG genotype at the rs200522762 locus had a lower risk than those carrying the GT+TT genotypes (P<0.05). Polymorphisms at the other six SNPs loci were not associated with NIHL risk (all P>0.05). Conclusion The NOX4 rs200522762 polymorphism is associated with susceptibility to NIHL.

BACKGROUND:Traditional surgery for lumbar disc herniation involves extensive excision of tissue surrounding the nerve for decompression and removal of protruding lumbar intervertebral discs,which poses various risks and complications such as nerve damage causing paralysis,lumbar instability,herniation recurrence,intervertebral space infection,and adjacent vertebral diseases. OBJECTIVE:To propose the symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous technique for lumbar spine symmetrically decompression,showing the induced resorption of herniated nucleus pulpous phenomenon and early clinical efficacy,and then analyze its decompression mechanism. METHODS:214 patients with lumbar disc herniation at Department of Orthopedics,First Affiliated Hospital of Zhengzhou University from March 2021 to May 2023 were enrolled in this study.Among them,81 patients received conservative treatment as the control group,and 133 patients received symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous treatment as the trial group.Before surgery,immediately after surgery(7-14 days),and early after surgery(over 1 year),MRI images were used to measure the volume changes of lumbar disc herniation.CT images were used to measure the posterior displacement distance of the lumbar spinous process ligament complex,as well as the width and height of the lateral recess.Japanese Orthopaedic Association scores were used to evaluate the patient's neurological function recovery. RESULTS AND CONCLUSION:(1)Control group:81 patients with lumbar disc herniation were treated conservatively,with a total of 171 herniated lumbar discs.The average follow-up time was(22.7±23.1)months.The first and second MRI measurements of 171 herniated lumbar discs showed herniated lumbar disc volumes of(551.6±257.9)mm3 and(792.2±330.4)mm3,respectively,with an average volume increase rate of(53.2±44.4)%,showing statistically significant differences(P<0.001).Out of 171 herniated lumbar discs,4 experienced natural shrinkage,with an absorption ratio of 2.3%(4/171)and an absorption rate of(24.5±9.9)%.(2)Trial group:133 patients with lumbar disc herniation had a total of 285 herniated lumbar discs.(1)Immediately after surgery:All patients were followed up immediately after surgery.229 out of 285 herniated lumbar discs experienced retraction,with an absorption ratio of 80.3%(229/285)and an average absorption rate of(21.5±20.9)%,with significant and complete absorption accounting for 6.5%.There were a total of 70 herniated lumbar discs in the upper lumbar spine,with an absorption ratio of 85.7%(60/70),an average absorption rate of(23.1±19.5)%,and a maximum absorption rate of 86.6%.There were 215 herniated lumbar discs in the lower lumbar spine,with an absorption ratio of 78.6%(169/215),an average absorption rate of(21.0±21.3)%,and a maximum absorption rate of 83.2%.Significant and complete absorption of the upper and lower lumbar vertebrae accounted for 5.7%and 6.5%,respectively,with no statistically significant difference(P>0.05).The average distance of posterior displacement of the spinous process ligament complex immediately after surgery was(5.2±2.8)mm.There were no significant differences in the width and height of the left and right lateral recess before and immediately after surgery(P>0.05).The Japanese Orthopaedic Association score immediately after surgery increased from(10.1±3.4)before surgery to(17.0±4.8),and the immediate effective rate after surgery reached 95.6%.(2)Early postoperative period:Among them,46 patients completed the early postoperative follow-up.There were 101 herniated lumbar discs,with an absorption ratio of 94%(95/101)and an average absorption rate of(36.9±23.7)%.Significant and complete absorption accounted for 30.6%,with a maximum absorption rate of 100%.Out of 101 herniated lumbar discs,3 remained unchanged in volume,with a volume invariance rate of 2.97%(3/101).Out of 101 herniated lumbar discs,3 had an increased volume of herniated lumbar discs,with an increase ratio of 2.97%(3/101)and an increase rate of(18.5±18.4)%.The Japanese Orthopaedic Association score increased from preoperative(9.3±5.1)to(23.5±4.0),with an excellent and good rate of 93.4%.(3)The early postoperative lumbar disc herniation absorption ratios of the control group and trial group were 2.3%and 85.9%,respectively,with statistically significant differences(P<0.001).(4)Complications:There were two cases of incision exudation and delayed healing in the trial group.After conservative treatment such as dressing change,no nerve injury or death occurred in the incision healing,and no cases underwent a second surgery.(5)It is concluded that symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous is a new method for treating lumbar disc herniation that can avoid extensive excision of the"ring"nerve and achieve satisfactory early clinical efficacy.It does not damage the lumbar facet joints or alter the basic anatomical structure of the lateral recess,fully preserves the herniated lumbar discs,and can induce significant or even complete induced resorption of herniated nucleus pulpous.Symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous provides a new basis and method for the clinical treatment of lumbar disc herniation.

The accumulation of uremic toxins such as urea nitrogen, blood creatinine, and uric acid of patients with renal failure in vivo would lead to aggravated kidney damage. In this study, coated aldehyde oxy-starch (CAO) was used as an adsorbent to investigate its in vitro adsorption performance on renal failure indexes for urea, indoxyl sulfate (INS), monomethylamine (MMA), dimethylamine (DMA), uric acid (UA), and creatinine (Cr). The effects of variables such as pH, temperature, concentration, dosage, and time on the adsorption capacity of CAO were systematically investigated, employing analytical techniques of high-performance liquid chromatography (HPLC) and gas chromatography (GC). The results revealed that CAO exhibited a strong adsorption capacity for urea, INS, and MMA, alongside a moderate adsorption capacity for DMA, UA, and Cr. The adsorption kinetics and thermodynamic studies indicated that the adsorption of urea and UA by CAO were fitted in pseudo-first-order kinetics, and the adsorption isotherm aligned with the Freundlich adsorption model. The enthalpy change ΔH of urea in adsorption was in the range of 40 to 60 kJ·mol^-1, which demonstrated the presence of strong adsorption force due to the interactions of coordinating groups. The ΔH of UA was greater than 80 kJ·mol^-1, indicating the generation of chemical bonds during the adsorption. Both of them, Gibbs free energy ΔG was less than 0, within the range of -20 to 0 kJ·mol^-1, suggested that the adsorption of urea and UA by CAO occurred spontaneously as physical adsorption process. The adsorption entropy ΔS of urea and UA was > 0, which indicated an increase in entropy throughout the adsorption. The infrared spectroscopygram showed the formation of a chemical bond, specifically the imine bond, following the adsorption of urea by CAO, thereby indicating a chemical reaction during the adsorption. This study elucidates the adsorption mechanism of CAO on various indexes of renal failure, providing a scientific basis for its clinical usage.

Objective:To evaluate the efficacy and safety of blinatumomab in adult patients with relapsed/refractory(R/R)or measurable residual disease(MRD)positive B-cell acute lymphoblastic leukemia(B-ALL)in the real world.Methods:The clinical data of 30 B-ALL patients received at least 1 course of blinatumomab therapy in the Chinese PLA General Hospital from January 1st,2021 to December 31st,2023 were retrospectively analyzed,including pre-treatment baseline clinical feature,post-treatment complete response(CR),CR with partial hematologic recovery(CRh),CR with incomplete hematologic recovery(CRi),complete MRD response rate,MRD response rate(MRD＜10-4),overall survival(OS),and disease-free survival(DFS),as well as drug-related adverse reactions.Results:Among 5 patients who were not assessed 4 were MRD negative and 1 did not receive bone marrow biopsy.In the R/R B-ALL group(13 cases),11 patients achieved CR/CRh/CRi and 10 patients achieved complete MRD response.In MRD+group(12 cases),9 patients achieved overall MRD response and 7 patients achieved complete MRD response.The median follow-up time was 8.4(95％CI:6.3-10.4)months.The median OS was 15.5(95％CI:0.7-30.3)months in the R/R group,while not reached in the MRD+group.The median DFS of the two groups were not reached.Drug-related adverse reactions occurred in 22 patients,and pyrexia was the most common(13 cases).Grade ≥3 adverse reactions occurred in 15 patients,and neutropenia was the most common(9 cases).Cytokine release syndrome occurred in 6 patients,including 5 cases with grade 1 and 1 case with grade 3.No patients interrupted therapy or died due to drug-related adverse reactions.Conclusion:Blinatumomab is effective in the treatment of R/R or continuous MRD+B-ALL with acceptable adverse reactions.

This study analyzed the clinical characteristics,diagnosis,treatment,and outcomes of disseminated Tsalaromycosis marneffei(DTSM)in non-HIV-infected patients.A retrospective analysis was conducted on 20 cases of non-HIV-infected DTSM treated at Guangzhou Chest Hospital between January 2015 and December 2021.Clinical data,including demographic characteris-tics,time to diagnosis,clinical manifestations,comorbidities,treatment details,and outcomes,were collected and analyzed.Among the 20 cases,9 were in males,and 11 were in females;the median age was 46(range:1-70)years.The median time from symptom onset to definitive diagnosis was 12(range:1-24)months,and 16 cases were initially misdiagnosed with mycobacterial disease.More than half the patients exhibited four major clinical features:fever,lymphadenopathy,skin lesions,and bone lesions.Pulmonary imag-ing abnormalities were observed in 19 cases,and an average of(3.6±1.6)lung lobes were involved.The positive detection rate of multi-sample cultures(70%,14/20)was significantly higher than that identified through histopathological examination(25%,5/20)(χ2=8.120,P=0.004).Findings for all five patients with positive next-generation sequencing(NGS)results were further confirmed through pathogen culture or histopathology.After antifungal treatment,14 patients showed clinical improvement and were discharged.In conclusion,non-HIV-infected DTSM is characterized by complex clinical manifestations and extensive pulmonary involvement,thus leading to frequent misdiagnosis and diagnostic delays.Pathogen detection methods,such as multi-sample cultures and NGS,demonstrate superior diagnostic accuracy to histopathological examination.Early identification and standardized antifungal therapy are critical factors in determining patient outcomes.

Objective To investigate the efficacy of cannabidiol(CBD)in improving renal function and protecting the kidney in mice with unilateral ureteral obstruction(UUO).Methods A total of 24 healthy,8-week-old,WTC57BL/6 male mice were divided into the Sham group,UUO group and UUO+CBD group,with 8 rats in each group.The UUO models were established by ligating one side of the ureter and removing the contralateral kidney to ensure unilateral kidney hydronephrosis.In the UUO+CBD group,5 mg/kg CBD was intraperitoneally injected immediately after the operation,once a day for 10 days.The Sham and UUO groups were given the same amount of normal saline.Blood sample was collected through the inner canthus venous plexus of the orbit 24 hours after the last administration.The levels of serum creatinine(Scr),blood urea nitrogen(BUN),tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),superoxide dismutase(SOD),and malondialdehyde(MDA)were detected with an automatic biochemistry analyzer.The histopathological sections were prepared,the pathological changes of renal tissues were observed under a light microscope,and the pathological injuries were scored.Mitochondrial quantity and morphological structure changes were observed with a transmission electron microscopy.Results Compared with the Sham group,the UUO group exhibited significantly higher levels of Scr[(22.55±3.29)μmol/L vs.(12.11±3.32)μmol/L],BUN[(18.62±2.15)mmol/L vs.(10.05±1.19)mmol/L],TNF-α[(21.04±2.56)pg/mL vs.(9.26±0.47)pg/mL],IL-1β[(10.25±1.25)pg/mL vs.(5.44±0.99)pg/mL],and MDA[(31.26±1.17)nmol/mL vs.(17.12±1.39)nmol/mL],but significantly lower level of SOD[(90.26±2.11)U/mL vs.(136.54±3.05)U/mL],all P＜0.000 1.Compared with the UUO group,the UUO+CBD group showed a significant decrease in the levels of Scr[(16.82±0.89)μmol/L vs.(22.55±3.29)μmol/L],BUN[(14.35±0.99)mmol/L vs.(18.62±2.15)mmol/L],TNF-α[(16.29±0.88)pg/mL vs.(21.04±2.56)pg/mL],IL-1β[(6.23±0.95)pg/mL vs.(10.25±1.25)pg/mL],MDA[(20.36±1.23)nmol/mL vs.(31.26±1.17)nmol/mL],and renal pathological damage score[(1.88±0.64)vs.(2.50±0.76)],but a significant increase in SOD level[(117.84±1.57)U/mL vs.(90.26±2.11)U/mL],all P＜0.000 1.Under electron microscopy,mitochondrial swelling,loss of inner membrane structure,and membrane rupture were observed in the UUO group,while the UUO+CBD group showed milder morphological changes.Conclusion CBD improves renal function in UUO model mice through anti-inflammatory,antioxidant and mitochondrial protection,and is a potential therapeutic drug for renal protection in clinic.

Objective:To correlate serum bone morphogenetic protein-2 (BMP-2) and cartilage oligomeric matrix protein (COMP) levels with joint function and systemic inflammatory response in patients with knee osteoarthritis (KOA) complicated by cartilage injury.Methods:This study is a retrospective analysis. It selected 258 patients with knee osteoarthritis who were treated at Yantai Yuhuangding Hospital from January 2022 to December 2023. All patients underwent arthroscopic examination. Based on the presence of cartilage injury, 118 patients with cartilage injury were included in the Group A, while 140 patients without cartilage injury were included in the Group B. Joint function (WOMAC Osteoarthritis Index, Lysholm Knee Function Score), serum levels of BMP-2 and COMP, and systemic inflammatory responses [levels of interleukin (IL)-1, IL-6, and tumor necrosis factor-alpha (TNF-α)] were compared between the two groups. Receiver Operating Characteristic (ROC) curves were drawn to analyze the diagnostic efficacy of serum BMP-2 and COMP levels for KOA complicated by cartilage injury. Pearson correlation analysis was used to assess the correlation between the aforementioned serum markers and the patients' WOMAC Osteoarthritis Index, Lysholm Knee Function Score, as well as serum levels of IL-1, IL-6, and TNF-α.Results:Group A had significantly lower serum BMP-2 levels and Lysholm Knee Function Scores compared with Group B [(9.18 ± 1.65) ng/L vs. (11.43 ± 2.51) ng/L, t = 8.34, P < 0.001; (80.06 ± 8.34) vs. (86.94 ± 7.21), t = 7.11, P < 0.001]. Group A exhibited higher serum levels of COMP, IL-1, IL-6, and TNF-α, as well as a higher WOMAC Osteoarthritis Index, with all differences being statistically significant [(6.88 ± 2.34) μg/L vs. (5.04 ± 1.01) μg/L, t = -8.34, P < 0.001; (43.18 ± 7.81) ng/L vs. (35.96 ± 5.02) ng/L, t = -8.96, P < 0.001; (34.03 ± 6.68) ng/L vs. (28.75 ± 5.61) ng/L, t = -6.90, P < 0.001; (13.17 ± 1.89) ng/L vs. (11.24 ± 1.01) ng/L, t = -10.44, P < 0.001; (137.18 ± 18.95) vs. (121.14 ± 13.58), t = -7.90, P < 0.001]. ROC curve analysis indicated that the area under the curve values for serum BMP-2 and COMP levels in diagnosing KOA complicated by cartilage injury were 0.773 and 0.811, respectively. Pearson correlation analysis revealed a negative correlation between serum BMP-2 levels and the WOMAC Osteoarthritis Index, as well as serum levels of IL-1, IL-6, and TNF-α ( r = -0.52, -0.42, -0.40, -0.57, all P < 0.05). Additionally, serum BMP-2 levels showed a positive correlation with the Lysholm Knee Function Score ( r = 0.51, P < 0.05). Serum COMP levels and the WOMAC Osteoarthritis Index were positively correlated with serum IL-1, IL-6, and TNF-α levels ( r = 0.48, 0.45, 0.37, 0.54, all P < 0.05) and were negatively correlated with the Lysholm Knee Function Score ( r = -0.51, P < 0.05). Conclusions:Serum BMP-2 and COMP levels have certain diagnostic value in patients with KOA complicated by cartilage injury. Moreover, these indicators are correlated with joint function and systemic inflammatory responses. Therefore, they hold promise as potential indicators for assessing disease progression in patients with KOA.
