AIM:To investigate the effects of the γ-aminobutyric acid(GABAergic)neural pathway from the anterior cingulate cortex(ACC)to the nucleus accumbens(NAc)on the regulation of irritable bowel syndrome(IBS)and its underlying mechanisms in mice.METHODS:(1)A C57BL/6J mice model of IBS was established by using chronic acute combing stress(CACS).The mice were divided into a normal group and an IBS group(n=8).The presence of IBS-like symptoms was determined through behavioural tests,an intestinal motility test and abdominal withdrawal reflex scores.(2)Fluorescence gold(FG)retrograde tracing and immunohistochemistry were used to investigate the ACC-NAc GABAergic neural pathway and to examine the activation of GABA in the ACC in IBS mice(n=8).(3)A total of 1.5 μL of normal saline(NS),GABAA receptor antagonist bicuculline(BIC)or agonist isoguvacine hydrochloride(Isog)was ad-ministered via a preburied catheter into the NAc of mice in IBS and normal groups.The mice were randomly divided into three groups(n=8):NS group,BIC group and Isog group.IBS-like symptoms were assessed.(4)The mice were prein-jected with AAV2/9-mDlx-iCre-WPRE-pA in the ACC and AAV2/2Retro Plus-hSyn-DIO-hM3D(Gq)-eGFP-WPRE-pA in the NAc and subsequently divided into four groups(n=8):NS(intraperitoneal injection)+NS(NAc microinjection)group,NS+BIC group,clozapine N-oxide(CNO)+NS group and CNO+BIC group.The mice who received AAV2/2Retro-hSyn-DIO-hM4D(Gi)-EGFP-WPRE-pA in the NAc were randomly divided into three groups(n=8):NS+NS group,NS+BIC group and CNO+NS group.Enzyme-linked immunosorbent assay(ELISA)was employed to estimate the expression levels of histamine and 5-hydroxytryptamine(5-HT)in colon tissue,and the effects of GABAergic neural pathways from ACC to NAc on IBS were studied.RESULTS:CACS induced IBS-like symptoms in mice.The results of FG retrograde tracing combined with fluorescence immunohistochemistry showed that GABA neurons of ACC could project to NAc.The injection of BIC in the NAc was found to significantly reduce anxiety-like behaviours,diarrheal symptoms and visceral hy-persensitivity in the IBS mice(P<0.05).Chemogenetic inhibition of the ACC-NAc GABAergic neurons ameliorated IBS-like symptoms in mice(P<0.05).CONCLUSION:The GABAergic pathway of ACC-NAc might be involved in the regu-lation of IBS in mice,which may be related to the release of histamine and 5-HT in colon tissue.

AIM:To investigate whether Miaoyao Tongfeng prescription(MTP)attenuates oxidative stress in-jury in gouty arthritis rats by regulating Kelch-like epicklorohydrin-related protein 1(Keap1)/nuclear factor E2-related fac-tor 2(Nrf2)signaling pathway.METHODS:Fifty male Sprague-Dawley rats were randomly divided into control group,model group,MTP group,Nrf2 inhibitor all-trans retinoic acid(ATRA)group and MTP+ATRA group.The 3%potassium oxonate solution(10 mL/kg)was injected intraperitoneally twice a day for 1 week,and then 0.2 mL sodium urate suspen-sion(25 g/L)was injected into the right knee joints to establish the gouty arthritis model.All rats were sacrificed 48 h af-ter modeling.Grades of swelling in the knee joints were evaluated,and HE staining was used to observe the pathological changes of knee joints.Serum levels of superoxide dismutase(SOD),malondialdehyde(MDA)and interleukin-1β(IL-1β)were detected using kits.The mRNA levels of Nrf2,Keap1,heme oxygenase-1(HO-1),IL-1β,NAD(P)H:quinone oxidoreductase 1(NQO1)in the synovial membrane of the knee joints were detected by qRT-PCR.Western blot was used to detect the expression of Nrf2,Keap1 and NQO1 in the synovial membrane of the knee joints.RESULTS:Compared with model group,MTP significantly reduced the degree of knee joint swelling,and attenuated the pathological injury of knee synovial membrane.It also inhibited the expression of MDA and IL-1β,but increased the expression of SOD.The mRNA expression of HO-1,and the mRNA and protein expression of Nrf2 and NQO1 in synovium were up-regulated,while the levels of IL-1β mRNA,Keap1 mRNA and Keap1 protein were down-regulated.CONCLUSION:Miaoyao Tongfeng prescription shows promise in the prevention and treatment of gouty arthritis through regulating Nrf2 and down-stream anti-oxidation genes.

BACKGROUND:Studies have shown that atorvastatin can up-regulate the expression of heme oxygenase-1 and enhance the anti-inflammation and anti-oxidative damage ability of cells.However,whether atorvastatin can regulate macrophage polarization,inhibit inflammation and reduce cholesterol accumulation by inducing heme oxygenase-1 expression remains unclear. OBJECTIVE:To investigate the effect of atorvastatin on polarization,inflammation and cholesterol content of oxidized low-density lipoprotein stimulated RAW264.7 macrophages by inducing heme oxygenase-1 expression and its related mechanism. METHODS:Firstly,RAW264.7 cells were randomly divided into six groups and incubated with different concentrations of atorvastatin for 24 hours.The expression of heme oxygenase-1 protein and cell activity were detected to explore the optimal dose of atorvastatin for subsequent studies.RAW264.7 cells were randomly divided into control group,atorvastatin group and heme oxygenase-1 inhibition group.Cells were preincubated with pure medium,atorvastatin 20 μmol/L and atorvastatin 20 μmol/L + zinc protoporphyrin IX 10 μmol/L for 24 hours,and then oxidized low-density lipoprotein 50 mg/L was added for 48 hours.The polarization of macrophages was detected by flow cytometry.The secretion of inflammatory factors such as transforming growth factor β,interleukin 10,interleukin 1β,and tumor necrosis factor α was detected by ELISA.The expression levels of heme oxygenase-1,LC3II,LC3I,P62,PPARγ and ABCA1 were detected by western blot assay.The intracellular cholesterol content was measured with the oxidose method and the accumulation degree of intracellular lipid droplets was evaluated by oil red O staining. RESULTS AND CONCLUSION:(1)Atorvastatin could induce the expression of heme oxygenase-1 protein in macrophages in a dose-dependent manner.(2)Oxidized low-density lipoprotein could induce macrophages to polarize towards M1,secrete proinflammatory factors,and increase the accumulation of intracellular cholesterol.(3)Compared with the control group,the heme oxygenase-1 protein expression of macrophages was increased after atorvastatin intervention,and the cells turned to M2-type polarization and mainly secreted anti-inflammatory factors such as transforming growth factor-β and interleukin-10.PPARγ,ABCA1,LC3II/I and other signal molecules reflecting cholesterol efflux and autophagy increased,and the contents of intracellular cholesterol and lipid droplets decreased significantly(P<0.05).(4)The heme oxygenase-1 inhibition group treated with zinc protoporphyrin IX significantly reversed the above changes in the atorvastatin group.(5)The results have shown that atorvastatin may promote the polarization of macrophages stimulated by oxidized low-density lipoprotein to M2 type and inhibit inflammation by up-regulating the expression of heme oxygenase-1 and by up-regulating PPARγ/ABCA1 signaling pathway and enhancing autophagy.Atorvastatin can increase the outflow of intracellular cholesterol and reduce the accumulation of intracellular lipids.

BACKGROUND:Laser therapy is a non-invasive and painless treatment that is considered to be an effective method suitable for the treatment of osteoarthritis due to its simplicity and non-invasive nature.Currently,the mechanism of action of laser therapy is unclear and the results of studies on its clinical application are controversial. OBJECTIVE:To review and summarize the latest research progress of laser therapy on chondrocytes,animal experiments and clinical efficacy,and to explore the possible mechanism of laser-mediated multi-pathway biological effects,so as to provide a theoretical basis for further research on the laser treatment of osteoarthritis of the knee joint. METHODS:A literature search was performed in CNKI,WanFang Data,VIP and PubMed databases for relevant literature published from 2018 to 2023,with"laser therapy,low level laser therapy,high level laser therapy,photobiomodulation,knee osteoarthritis,chondrocytes"as the search terms in Chinese and English,respectively.Together with 14 articles searched manually,70 articles were finally included for review. RESULTS AND CONCLUSION:Laser therapy in the treatment of knee osteoarthritis is mainly categorized into two types:low-level laser therapy and high-level laser therapy.Differences in laser parameters and treatment protocols have a direct impact on laser efficacy.When appropriate parameters are used,low-level lasers show positive effects in cellular experiments,animal models,and clinical efficacy.High-level lasers have been less studied in the treatment of knee osteoarthritis,but some preliminary clinical studies have shown positive results.Cell experiments have shown that low-level laser promotes chondrocyte proliferation and cartilage matrix synthesis,thereby reducing inflammatory response.Animal experiments have shown that low-level laser can reduce the release of pro-inflammatory factors,promote cartilage matrix synthesis,inhibit matrix degradation,and effectively improve the repair process of cartilage tissue.Low-level laser is also able to reduce oxidative stress damage and relieve pain in knee osteoarthritis.In clinical trials,both low-and high-level laser can reduce patients'pain and improve functional activities.The combination of laser therapy and exercise therapy modalities may improve the therapeutic effect.Lasers may affect intracellular signaling and cellular functions through photobiological or thermodynamic effects.This provides direct evidence that laser promotes articular cartilage regeneration.

OBJECTIVE To evaluate the cost-effectiveness of omalizumab in the treatment of severe allergic asthma from the perspective of healthcare providers in China. METHODS Based on the data from an international multicenter study of omalizumab in the treatment of severe allergic asthma， the Markov model was constructed according to the progression of severe allergic asthma， with a cycle of 4 weeks. Long-term health outcomes and costs of omalizumab combined with standard of care（SoC） regimen versus SoC regimen in the treatment of severe allergic asthma were simulated by using quality-adjusted life years （QALYs） and incremental cost-effectiveness ratio（ICER） as output indexes. One-way sensitivity analysis， probabilistic sensitivity analysis， and scenario analysis were performed to test the robustness of the results. RESULTS Compared with the SoC regimen， ICER for the omalizumab combined with SoC regimen was 107 723.05 yuan/QALY， which was less than the willingness-to-pay（WTP） threshold （268 074 yuan/QALY） calculated by three times per capita gross domestic product（GDP） in China in 2023. The one-way sensitivity analysis showed that the baseline serum level of immunoglobulin E had the greatest impact on the robustness of the model. The probabilistic sensitivity analysis showed that the omalizumab+SoC regimen had a 93.00% probability of being cost- effective. The scenario analysis showed that in the real world， the billing method of omalizumab based on specifications rather than actual usage may increase ICER. CONCLUSIONS Compared with the SoC regimen， the combination of omalizumab and SoC regimen for treating severe allergic asthma is cost-effective， with a WTP threshold of three times China’s per capita GDP
