ObjectiveTo explore the effect of respiratory training based on core stabilization training on lumbar disc herniation. MethodsFrom January, 2023 to October, 2024, 96 patients with lumbar disc herniation admitted to the First Affiliated Hospital of Bengbu Medical University were divided into control group (n = 32), core group (n = 32) and respiratory group (n = 32). All the groups underwent conventional rehabilitation therapy, with core stabilization training in the core group and respiratory training combined with core stabilization training in the respiratory group, additionally, for four weeks. Before and after training, the scores of Visual Analogue Scale, Japanese Orthopaedic Association (JOA) and Oswestry Dysfunction Index (ODI) were compared, the average electromyographic value (AEMG) and root mean square (RMS) value of the multifidus and transversus abdominis were detected by surface electromyography (sEMG); and the thickness of the multifidus and transversus abdominis were measured by musculoskeletal ultrasonography bilaterally. ResultsThe intra-group effect (F > 597.796, P < 0.001), inter-group effect (F > 16.535, P < 0.001) and interaction effect (F > 49.622, P < 0.001) were significant in the scores of VAS, JOA and ODI; which were better in the respiratory group than in the control group and the core group (P < 0.05), and were better in the core group than in the control group (P < 0.001). The intra-group effect (F > 7971.631, P < 0.001), inter-group effect (F > 177.760, P < 0.001) and interaction effect (F > 478.771, P < 0.001) were significant in the thickness of the transversus abdominis and multifidus; which were better in the respiratory group than in the control group and the core group (P < 0.001), and were better in the core group than in the control group (P < 0.001). The intra-group effect (F > 144303.007, P < 0.001), inter-group effect (F > 1495.458, P < 0.001) and interaction effect (F > 3121.361, P < 0.001) were significant in the RMS of the multifidus and transversus abdominis; which were better in the respiratory group than in the control group and the core group (P < 0.001), and were better in the core group than in the control group (P < 0.001). The intra-group effect (F > 1890.532, P < 0.001), inter-group effect (F > 607.132, P < 0.001) and interaction effect (F > 824.923, P < 0.001) were significant in the AEMG of the multifidus and transversus abdominis; which were better in the respiratory group than in the control group and core group (P < 0.001), and were better in the core group than in the control group (P < 0.001). ConclusionCore training combined with respiratory training can more effectively reduce pain and improve dysfunction by enhancing the strength and control of the core muscles， thus improving the quality of life of patients with lumbar disc herniation.

BACKGROUND:Gradient artificial bone repair scaffolds can mimic unique anatomical features in musculoskeletal tissues,showing great potential for repairing injured musculoskeletal tissues. OBJECTIVE:To review the latest research advances in gradient artificial bone repair scaffolds for tissue engineering in the musculoskeletal system and describe their advantages and fabrication strategies. METHODS:The first author of the article searched the Web of Science and PubMed databases for articles published from 2000 to 2023 with search terms"gradient,bone regeneration,scaffold".Finally,76 papers were analyzed and summarized after the screening. RESULTS AND CONCLUSION:(1)As an important means of efficient and high-quality repair of skeletal system tissues,gradient artificial bone repair scaffolds are currently designed bionically for the natural gradient characteristics of bone tissue,bone-cartilage,and tendon-bone tissue.These scaffolds can mimic the extracellular matrix of native tissues to a certain extent in terms of structure and composition,thus promoting cell adhesion,migration,proliferation,differentiation,and regenerative recovery of damaged tissues to their native state.(2)Advanced manufacturing technology provides more possibilities for gradient artificial bone repair scaffold preparation:Gradient electrospun fiber scaffolds constructed by spatially differentiated fiber arrangement and loading of biologically active substances have been developed;gradient 3D printed scaffolds fabricated by layered stacking,graded porosity,and bio-3D printing technology;gradient hydrogel scaffolds fabricated by in-situ layered injections,simple layer-by-layer stacking,and freeze-drying method;and in addition,there are also scaffolds made by other modalities or multi-method coupling.These scaffolds have demonstrated good biocompatibility in vitro experiments,were able to accelerate tissue regeneration in small animal tests,and were observed to have significantly improved histological structure.(3)The currently developed gradient artificial bone repair scaffolds have problems such as mismatch of gradient scales,unclear material-tissue interactions,and side effects caused by degradation products,which need to be further optimized by combining the strengths of related disciplines and clinical needs in the future.

Diabetic nephropathy (DN), as one of the most common complications of diabetes, is a primary cause of end-stage renal disease. The pathogenesis of DN encompasses processes such as chronic inflammation, recruitment and activation of immune cells, tubular and glomerular injury, and renal fibrosis. These processes are highly correlated with the activation of the nucleotide-binding oligomerization domain-like receptor pyrin domain containing 3 (NLRP3) inflammasome and the resulting pyroptosis it mediates. Previous studies have shown that the release of pro-inflammatory cytokines, leakage of damage-associated molecular patterns (DAMPs), recruitment and activation of immune cells can be reduced by regulating the NLRP3 inflammasome and its mediated pyroptosis, thereby slowing the diffusion of inflammatory responses in adjacentcells, fibrosis, and tissue remodeling processes. Ultimately, these process can improve renal injury and dysfunction caused by diabetic nephropathy. This article summarizes the molecular regulatory mechanisms of the NLRP3 inflammasome and its mediated pyroptosis at different pathological stages of DN, proposes potential targets for regulating their activation, aiming to provide a new direction for personalized treatment of DN.

A derivatizaton method combined with gas chromatography-mass spectrometry(GC-MS)was established for detection of isobutyl chloroformate(IBCF)residue in active pharmaceutical ingredient of agatroban.The extraction and derivatization reagents,derivatization time,qualitative and quantitative ions were selected and optimized,respectively.The possible mechanism of derivatization and characteristic fragment ions fragmentation were speculated.The agatroban samples were dissolved and extracted by methanol,and the residual IBCF was derived with methanol to generate methyl isobutyl carbonate(MIBCB).After 24 h static derivatization at room temperature,IBCF was completely transformed into MIBCB,which could be used to indirectly detect IBCF accurately.The results showed that the linearity of this method was good in the range of 25-500 ng/mL(R2=0.9999).The limit of detection(LOD,S/N=3)was 0.75 μg/g,and the limit of quantification(LOQ,S/N=10)was 2.50 μg/g.Good recoveries(95.2%-97.8%)and relative standard deviations(RSDs)less than 3.1%(n=6)were obtained from agatroban samples at three spiked levels of IBCF(2.50,25.00,50.00 μg/g),which showed good accuracy of this method.Good precision of detection results was obtained by different laboratory technicians at different times,the mean value of spiked sample solution(25.00 μg/g)was 24.28 μg/g,and the RSD was 2.1%(n=12).The durability was good,minor changes of detection conditions had little effect on the results.Under the original condition and conditions with initial column temperature±5℃,heating rate±2℃/min,column flow rate±0.1 mL/min,the IBCF content of spiked sample solution(25.00 μg/g)was detected,the mean value of detection results was 24.16 μg/g,and the RSD was 2.2%(n=7).Eight batches of agatroban samples from two manufacturers were detected using the established method,and the results showed that no IBCF residue was detected in any of these samples.The agatroban samples could be dissolved by methanol,and then the IBCF residue could be simultaneously extracted and derived with methanol as well.This detection method had the advantages of simple operation,high sensitivity,low matrix effect and accurate quantification,which provided a new effective method for detection of IBCF residue in agatroban.

Objective To evaluate the efficacy of XELOX regimen as neoadjuvant chemotherapy in the treatment of stage Ⅱ and Ⅲ colon cancer.Methods The clinical data of 50 patients with clinical stage Ⅱ(T4)Ⅲ colon cancer who underwent laparoscopic radical resection at general surgery department of our hospital from January 1,2012 to January 1,2021 were retrospectively analyzed.Patients were divided into neoadjuvant chemotherapy group(NACT)and adjuvant chemotherapy group(ACT)according to whether they received neoadjuvant chemotherapy with XELOX regimen.The general clinical data,adverse reactions of chemotherapy,surgical complications,operation time,intraoperative blood loss,hospitalization time,hospitalization cost,negative conversion rate of tumor markers,tumor remission rate,tumor downstaging rate,tumor response grade after chemotherapy,postoperative disease-free survival curve,and overall survival curve were retrospectively analyzed and compared among the groups.Results There were no significant differences in operative complications,postoperative exhaust time and hospital stay between NACT group and ACT group(P＞0.05).The adverse reactions of chemotherapy,the negative conversion rate of postoperative CEA and CA19-9,the duration of operation,the amount of bleeding,and the hospitalization cost in NACT group were significantly better than those in ACT group(P＜0.05).In terms of DFS and OS survival curves,with the extension of time,the decline of the NACT survival curve was smaller than that of the ACT group,and there was a significant difference in DFS survival curve(P＜0.05),but no significant difference in OS survival curve(P＞0.05).Conclusion XELOX neoadjuvant chemotherapy is safe and effective in the treatment of stage Ⅱ(T4)and stage Ⅲcolon cancer.

OBJECTIVE To mine the adverse drug events （ADE） signals for gilteritinib， and provide a reference for safe drug use in clinic. METHODS ADE reports with gilteritinib as the primary suspected drug were extracted from the FDA Adverse Event Reporting System （FAERS） database from February 1st， 2018 to December 31st， 2023. Reporting odds ratio （ROR） and proportional reporting ratio （PRR） were applied to detect the risk signals from the data in the FAERS database. The classification and statistics of collected signal data were conducted by using the preferred term （PT） and systemic organ class （SOC） in ADE terminology set of the Medical Dictionary for Regulatory Activities （24.1 edition）. RESULTS Totally， 2 755 gilteritinib-related ADE reports were collected from the database， involving 676 ADE signals （95 positive signals）， 313 PTs and 25 SOCs. Among them， nine signals were not recorded in the package insert. The top 5 PTs consisted of abnormal liver function， decreased platelet count， febrile neutropenia， pneumonia and myelosuppression. The top 6 SOCs for positive signal counts were examinations， general disorders and administration site conditions， respiratory， thoracic and mediastinal disorders， infections and infestations， heart organ disorders， and nervous system disorders. ADEs not recorded in the drug package insert included pneumonia， myelosuppression， decreased blood cell count， sepsis， hemorrhage， infection （not specifically referred to）， septic shock， respiratory failure， and aspergillosis. CONCLUSIONS In addition to paying attention to common ADEs such as liver dysfunction and thrombocytopenia， it is necessary to monitor ADEs with strong signals that are not mentioned in the drug instructions when using gefitinib， such as pneumonia， bone marrow suppression， cytopenia， sepsis， bleeding， infection （not specifically referred to）， septic shock， respiratory failure， Aspergillus infection， elevated serum creatinine and interstitial lung disease.

OBJECTIVE To investigate the protective effect of paeoniflorin(PF) on cardiac dysfunction and myocardial cell injury induced by cisplatin(CDDP) in rats. METHODS SD male rats were randomly divided into control group, CPPD group, and CDDP PF+low-dose, high-dose group. PowerLab multifunctional recorder was used to detect the related indexes of cardiac function: the changes of left ventricular peak pressure(LVSP), left ventricular end-diastolic pressure(LVEDP) and left ventricular pressure change rate(±dp/dt). Serum levels of inflammatory factors TNF-α, IL-1β and IL-6 were measured in each group. Myocardial tissue was stained to observe the changes of tissue structure. H9c2 cardiomyocytes were divided into control group, CDDP group, PF group and CDDP+PF group. The activity of H9c2 cardiomyocytes was measured by CCK-8. The apoptosis of cardiomyocytes in each group was detected by flow cytometry. The expressions of MAPK signaling pathway related proteins p38, ERK, JNK and their phosphorylated proteins and apoptosis-related proteins Bax, Bcl-2, Casp3, Cl-casp3 were detected in cardiomyocytes by Western blotting. RESULTS Compared with the control group, LVSP and ±dp/dt decreased, LVEDP increased in rats of CDDP group(P<0.01). Compared with CDDP group, both CDDP+low-dose and high-dose PF pretreatment increased LVSP and ±dp/dt value(P<0.05 or P<0.01), decreased LVEDP(P<0.01), and could decrease the serum inflammatory factor TNF-α, IL-1β and IL-6(P<0.01). Cell level results showed that compared with control group, in CDDP group, the cell activity decreased, the apoptosis-related protein Bax, Cl-casp3 increased(P<0.01), expression of anti-apoptotic protein Bcl-2 decreased(P<0.01), and the expression of p38 and ERK phosphorylation also increased(P<0.01). Compared with CDDP group, PF could restore cell activit, down-regulate apoptosis-related protein Bax, Cl-casp3(P<0.05 or P<0.01), and increase anti-apoptotic protein Bcl-2 expression(P<0.01), inhibit MAPK pathway p38 and ERK phosphorylation expression(P<0.01). CONCLUSION PF can restore cardiac dysfunction and myocardial cell injury induced by cisplatin in rats, which may be related to inhibiting inflammation and apoptosis by regulating ERK/p38 MAPK signal expression.
