Seventy male rats were randomly divided into seven groups: Healthy controls(HC), ulcerative colitis model group(UC), UC with 7 d of moxibustion(UC-7), UC with 14 d of moxibustion(UC-14), UC with mesalazine gavage(UC-W), HC with 7 d of moxibustion(HC-7), HC with 14 d of moxibustion(HC-14). Moxibustion was applied to the bilateral Tianshu(ST25). Gut microbiome profiling was conducted by 16 S r RNA amplicon sequencing, and PCR and ELISA determined the expression of inflammatory cytokines in colon mucosa and serum, respectively. RESULTS Moxibustion treatment restored the colonic mucosa and decreased submucosal inflammatory cell infiltration in colitis rats. Rats treated with moxibustion and mesalazine had significantly lower levels of the dominant phyla Proteobacteria and the genera Saccharibacteria, Sphingomonas and Barnesiella than colitis rats, and they could restore the microbiome to levels similar to those observed in healthy rats. UC rats had reduced alpha diversity, which could be alleviated by moxibustion therapy, and UC-7 had a higher alpha diversity than UC-14. This finding suggests that short-term(7 d) but no longer term(14 d) moxibustion treatment may significantly affect the gut microbiome. The potential bacterial functions affected by moxibustion may be ascorbate and aldarate metabolism, and amino acid metabolism. Compared with HC group, the levels of the cytokines interleukin-12(IL-12)(P < 0.05) and IL-6, IL-17, IL-23, interferon-γ, lipopolysaccharide, Ig A, tumour necrosis factor-α and its receptors 1(TNFR1) and TNFR2(P < 0.01) were all increased, whereas anti-inflammatory cytokine IL-2 and IL-10(P < 0.01) and transforming growth factor-β(P < 0.05) were decreased in UC rats. These changes were reversed by moxibustion.CONCLUSION Our findings suggest that moxibustion exerts its therapeutic effect by repairing mucosal tissue damage and modulating the gut microbiome and intestinal mucosal immunity.展开更多

In the 7th week after the procedure, rats were randomly divided into a model group(MG), electroacupuncture group(EA), and sham electroacupuncture group(S-EA). After treatment, the abdominal withdrawal reflex(AWR) score was used to assess the behavioral response of visceral hyperalgesia. Immunohistochemistry(En Vision method), ELISA, and fluorescence quantitative PCR methods were applied to detect the expression of CRH protein and m RNA in the colon, spinal cord, and hypothalamus.RESULTS: The sensitivity of the rats to the colorectal distension stimulus applied at different strengths(20-80 mm Hg) increased with increasing stimulus strength, resulting in increasing AWR scores in each group. Compared with NG, the AWR score of MG was significantly increased(P < 0.01). After conducting EA, the AWR scores of the rats were decreased compared with MG rats. The relative expression of CRH m RNA in the colon, spinal cord, and hypothalamus of MG rats was significantly increased compared with NG rats(P < 0.01). CRH m RNA in the colon and spinal cord of EA and S-EA rats was decreased to varying degrees(P > 0.05) compared with normal rats(NG). However, the decrease in EA compared with MG rats was statistically significant(P < 0.01). The average optical density of CRH expression in the colon of the MG rats was significantly enhanced compared with NG(P < 0.05), while the average optical density of CRH expression in the EA and S-EA rats was significantly decreased compared with MG rats(P < 0.01, P < 0.05, respectively). Compared with MG rats, the CRH concentration in the spinal cord of EA rats was significantly reduced(P < 0.01), but there was no significant change in S-EA rats(P > 0.05).CONCLUSION: Electroacupuncture at the Shangjuxu acupoint was able to significantly reduce the visceral hypersensitivity in rats, and regulated the expression of CRH protein and m RNA in the colon, spinal cord and hypothalamus at different levels, playing a therapeutic role in this model of irritable bowel syndrome.展开更多

METHODS: A rat model of UC was established by local stimulation of the intestine with supernatant from colonic contents harvested from human UC patients. A total of 40 male Sprague-Dawley rats were randomly divided into the following groups: normal (sham), model (UC), herb-partition moxibustion (HPM-treated), and positive control sulfasalazine (SA-treated). Rats treated with HPM received HPM at acupuncture points ST25 and RN6, once a day for 15 min, for a total of 8 d. Rats in the SA group were perfused with SA twice a day for 8 d. The colonic histopathology was observed by hematoxylin-eosin. The levels of intestinal flora, including Bifidobacterium, Lactobacillus, Escherichia coli (E. coli), and Bacteroides fragilis (B. fragilis), were tested by real-time quantitative polymerase chain reaction to detect bacterial 16S rRNA/DNA in order to determine DNA copy numbers of each specific species. Immunohistochemical assays were used to observe the expression of TNF-α and IL-12 in the rat colons. RESULTS: HPM treatment inhibited immunopathology in colonic tissues of UC rats; the general morphological score and the immunopathological score were significantly decreased in the HPM and SA groups compared with the model group [3.5 (2.0-4.0), 3.0 (1.5-3.5) vs 6.0 (5.5-7.0), P < 0.05 for the general morphological score, and 3.00 (2.00-3.50), 3.00 (2.50-3.50) vs 5.00 (4.50-5.50), P < 0.01 for the immunopathological score]. As measured by DNA copy number, we found that Bifidobacterium and Lactobacillus, which are associated with a healthy colon, were significantly higher in the HPM and SA groups than in the model group (1.395 ± 1.339, 1.461 ± 1.152 vs 0.045 ± 0.036, P < 0.01 for Bifidobacterium, and 0.395 ± 0.325, 0.851 ± 0.651 vs 0.0015 ± 0.0014, P < 0.01 for Lactobacillus). On the other hand, E. coli and B. fragilis, which are associated with an inflamed colon, were significantly lower in the HPM and SA groups than in the model group (0.244 ± 0.107, 0.628 ± 0.257 vs 1.691 ± 0.683, P < 0.01 for E. coli, and 0.351 ± 0.181, 0.416 ± 0.329 vs 1.285 ± 1.039, P < 0.01 for B. fragilis). The expression of TNF-α and IL-12 was decreased after HPM and SA treatment as compared to UC model alone (4970.81 ± 959.78, 6635.45 ± 1135.16 vs 12333.81 ± 680.79, P < 0.01 for TNF-α, and 5528.75 ± 1245.72, 7477.38 ± 1259.16 vs 12550.29 ± 1973.30, P < 0.01 for IL-12). CONCLUSION: HPM treatment can regulate intestinal flora and inhibit the expression of TNF-α and IL-12 in the colon tissues of UC rats, indicating that HPM can improve colonic immune response.展开更多

文摘BackgroundIrritable bowel syndrome(IBS)is a functional bowel disease characterized by abdominal pain or discomfort associated with altered bowel habits.Several clinical studies have demonstrated the effectiveness of acupuncture and moxibustion for IBS.Many systematic reviews of acupuncture and moxibustion for IBS have been published in recent years,but their results are not entirely consistent.ObjectiveTo evaluate the methodological,reporting,and evidence quality of systematic reviews of acupuncture and moxibustion for IBS.Search strategySystematic reviews of acupuncture and moxibustion for IBS published before February 20,2023 were searched in eight databases:PubMed,Embase,Cochrane Library,Web of Science,China National Knowledge Infrastructure,Wanfang Data,VIP Database for Chinese Technical Periodicals,and China Biology Medicine.The keywords used for literature search were acupuncture,moxibustion,systematic review,meta-analysis,and irritable bowel syndrome.Inclusion criteriaSystematic reviews and meta-analyses of randomized controlled trials of acupuncture and moxibustion for IBS were included.Data extraction and analysisRelevant information was independently extracted by two investigators.The A MeaSurement Tool to Assess systematic Reviews 2(AMSTAR 2),Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA 2020),and Grading of Recommendations Assessment,Development and Evaluation(GRADE)were used to evaluate the methodological quality,reporting quality and evidence quality,respectively.ResultsA total of 342 studies were retrieved and 15 systematic reviews were included.The results of AMSTAR 2 showed low methodological quality in 2 studies and very low methodological quality in the remaining 13 studies,with main issues being failure to register a protocol,incomplete search strategy,not providing a list of excluded studies,incomplete consideration of the risk of bias in the included studies,and a failure to assess the publication bias.The results of PRISMA 2020 showed seriously deficient reporting quality of 2 studies,somewhat deficient reporting quality of 12 studies,and relatively complete reporting quality of 1 study,with the main problems being lack of a complete search strategy,non-availability of a list of excluded studies with justification for their exclusion,not conducting heterogeneity and sensitivity analyses,not evaluating the credibility of the evidence,and not registering the protocol.The results of GRADE showed that the quality of the evidence is low or very low.ConclusionMost included systematic reviews interpreted findings to suggest that acupuncture and moxibustion have benefits for IBS.However,there is a need to improve the methodological,reporting and evidence quality of the systematic reviews.Larger,multicenter,rigorously designed randomized controlled trials and high-quality systematic reviews are required to obtain more robust evidence.

文摘BACKGROUND About one-third of refractory irritable bowel syndrome(IBS)cases are caused by gastrointestinal(GI)infection/inflammation,known as post-infectious/postinflammatory IBS(PI-IBS).Although it is known that intestinal microbiota and host NOD-like receptor family pyrin domain containing 6(NLRP6)inflammsome signaling are closely related to PI-IBS and moxibustion has a therapeutic effect on PI-IBS,whether moxibustion regulates the intestinal flora and host NLRP6 events in PI-IBS remains unclear.AIM To examine the regulatory effect of moxibustion on intestinal microbiota and host NLRP6 inflammatory signaling in PI-IBS.METHODS Sprague-Dawley rats were divided into a normal control group,a model control group,a mild moxibustion group,and a sham mild moxibustion group.PI-IBS rats in the mild moxibustion group were treated with moxibusiton at bilateral Tianshu(ST 25)and Zusanli(ST36)for 7 consecutive days for 10 min each time.The sham group rats were given the same treatment as the mild moxibustion group except the moxa stick was not ignited.Abdominal withdrawal reflex(AWR)score was measured to assess the visceral sensitivity,and colon histopathology and ultrastructure,colonic myeloperoxidase(MPO)activity,and serum C-reactive protein(CRP)level were measured to evaluate low-grade colonic inflammation in rats.The relative abundance of selected intestinal bacteria in rat feces was detected by 16S rDNA PCR and the NLRP6 inflammsome signaling in the colon was detected by immunofluorescence,qRTPCR,and Western blot.RESULTS The AWR score was significantly decreased and the low-grade intestinal inflammation reflected by serum CRP and colonic MPO levels was inhibited in the mild moxibustion group compared with the sham group.Mild moxibustion remarkably increased the relative DNA abundances of Lactobacillus,Bifidobacterium,and Faecalibacterium prausnitzii but decreased that of Escherichia coli in the gut of PI-IBS rats.Additionally,mild moxibustion induced mRNA and protein expression of intestine lectin 1 but inhibited the expression of IL-1β,IL-18,and resistance-like moleculeβby promoting the NLRP6 and reducing the mRNA and protein expression of apoptosis-associated speck-like protein containing CARD(ASC)and cysteinyl-aspartate-specific proteinase 1(Caspase-1).The relative DNA abundances of Lactobacillus,Bifidobacteria,Faecalibacterium prausnitzii,and Escherichia coli in each group were correlated with the mRNA and protein expression of NLRP6,ASC,and Caspase-1 in the colon.CONCLUSION These findings indicated that mild moxibustion can relieve low-grade GI inflammation and alleviate visceral hypersensitivity in PI-IBS by regulating intestinal microbes and controlling NLRP6 inflammasome signaling.

文摘AIM To investigate the effect and mechanism of moxibustion in rats with ulcerative colitis.METHODS A rat colitis model was established by administering 4% dextran sulphate sodium solution. Seventy male rats were randomly divided into seven groups: Healthy controls(HC), ulcerative colitis model group(UC), UC with 7 d of moxibustion(UC-7), UC with 14 d of moxibustion(UC-14), UC with mesalazine gavage(UC-W), HC with 7 d of moxibustion(HC-7), HC with 14 d of moxibustion(HC-14). Moxibustion was applied to the bilateral Tianshu(ST25). Gut microbiome profiling was conducted by 16 S r RNA amplicon sequencing, and PCR and ELISA determined the expression of inflammatory cytokines in colon mucosa and serum, respectively. RESULTS Moxibustion treatment restored the colonic mucosa and decreased submucosal inflammatory cell infiltration in colitis rats. Rats treated with moxibustion and mesalazine had significantly lower levels of the dominant phyla Proteobacteria and the genera Saccharibacteria, Sphingomonas and Barnesiella than colitis rats, and they could restore the microbiome to levels similar to those observed in healthy rats. UC rats had reduced alpha diversity, which could be alleviated by moxibustion therapy, and UC-7 had a higher alpha diversity than UC-14. This finding suggests that short-term(7 d) but no longer term(14 d) moxibustion treatment may significantly affect the gut microbiome. The potential bacterial functions affected by moxibustion may be ascorbate and aldarate metabolism, and amino acid metabolism. Compared with HC group, the levels of the cytokines interleukin-12(IL-12)(P < 0.05) and IL-6, IL-17, IL-23, interferon-γ, lipopolysaccharide, Ig A, tumour necrosis factor-α and its receptors 1(TNFR1) and TNFR2(P < 0.01) were all increased, whereas anti-inflammatory cytokine IL-2 and IL-10(P < 0.01) and transforming growth factor-β(P < 0.05) were decreased in UC rats. These changes were reversed by moxibustion.CONCLUSION Our findings suggest that moxibustion exerts its therapeutic effect by repairing mucosal tissue damage and modulating the gut microbiome and intestinal mucosal immunity.

文摘AIM: To investigate the effect of electroacupuncture on corticotropin-releasing hormone(CRH) in the colon, spinal cord, and hypothalamus of rats with chronic visceral hypersensitivity.METHODS: A rat model of chronic visceral hypersensitivity was generated according to the internationally accepted method of colorectal balloon dilatation. In the 7th week after the procedure, rats were randomly divided into a model group(MG), electroacupuncture group(EA), and sham electroacupuncture group(S-EA). After treatment, the abdominal withdrawal reflex(AWR) score was used to assess the behavioral response of visceral hyperalgesia. Immunohistochemistry(En Vision method), ELISA, and fluorescence quantitative PCR methods were applied to detect the expression of CRH protein and m RNA in the colon, spinal cord, and hypothalamus.RESULTS: The sensitivity of the rats to the colorectal distension stimulus applied at different strengths(20-80 mm Hg) increased with increasing stimulus strength, resulting in increasing AWR scores in each group. Compared with NG, the AWR score of MG was significantly increased(P < 0.01). After conducting EA, the AWR scores of the rats were decreased compared with MG rats. The relative expression of CRH m RNA in the colon, spinal cord, and hypothalamus of MG rats was significantly increased compared with NG rats(P < 0.01). CRH m RNA in the colon and spinal cord of EA and S-EA rats was decreased to varying degrees(P > 0.05) compared with normal rats(NG). However, the decrease in EA compared with MG rats was statistically significant(P < 0.01). The average optical density of CRH expression in the colon of the MG rats was significantly enhanced compared with NG(P < 0.05), while the average optical density of CRH expression in the EA and S-EA rats was significantly decreased compared with MG rats(P < 0.01, P < 0.05, respectively). Compared with MG rats, the CRH concentration in the spinal cord of EA rats was significantly reduced(P < 0.01), but there was no significant change in S-EA rats(P > 0.05).CONCLUSION: Electroacupuncture at the Shangjuxu acupoint was able to significantly reduce the visceral hypersensitivity in rats, and regulated the expression of CRH protein and m RNA in the colon, spinal cord and hypothalamus at different levels, playing a therapeutic role in this model of irritable bowel syndrome.

文摘BACKGROUND Autophagy is an evolutionarily conserved biological process in eukaryotic cells that involves lysosomal-mediated degradation and recycling of related cellular components.Recent studies have shown that autophagy plays an important role in the pathogenesis of Crohn’s disease(CD).Herbal cake-partitioned moxibustion(HM)has been historically practiced to treat CD.However,the mechanism by which HM regulates colonic autophagy in CD remains unclear.AIM To observe whether HM can alleviate CD by regulating colonic autophagy and to elucidate the underlying mechanism.METHODS Rats were randomly divided into a normal control(NC)group,a CD group,an HM group,an insulin+CD(I+CD)group,an insulin+HM(I+HM)group,a rapamycin+CD(RA+CD)group,and a rapamycin+HM(RA+HM)group.2,4,6-trinitrobenzenesulfonic acid was administered to establish a CD model.The morphology of the colonic mucosa was observed by hematoxylin-eosin staining,and the formation of autophagosomes was observed by electron microscopy.The expression of autophagy marker microtubule-associated protein 1 light chain 3 beta(LC3B)was observed by immunofluorescence staining.Insulin and rapamycin were used to inhibit and activate colonic autophagy,respectively.The mRNA expression levels of phosphatidylinositol 3-kinase class I(PI3KC1),Akt1,LC3B,sequestosome 1(p62),and mammalian target of rapamycin(mTOR)were evaluated by RT-qPCR.The protein expression levels of interleukin 18(IL-18),tumor necrosis factor-α(TNF-α),nuclear factorκB/p65(NF-κB p65),LC3B,p62,coiled-coil myosin-like BCL2-interacting protein(Beclin-1),p-mTOR,PI3KC1,class III phosphatidylinositol 3-kinase(PI3KC3/Vps34),and p-Akt were evaluated by Western blot analysis.RESULTS Compared with the NC group,the CD group showed severe damage to colon tissues and higher expression levels of IL-18 and NF-κB p65 in colon tissues(P<0.01 for both).Compared with the CD group,the HM group showed significantly lower levels of these proteins(PIL-18<0.01 and Pp65<0.05).There were no significant differences in the expression of TNF-αprotein in colon tissue among the rat groups.Typical autophagic vesicles were found in both the CD and HM groups.The expression of the autophagy proteins LC3B and Beclin-1 was upregulated(P<0.01 for both)in the colon tissues of rats in the CD group compared with the NC group,while the protein expression of p62 and p-mTOR was downregulated(P<0.01 for both).However,these expression trends were significantly reversed in the HM group compared with the CD group(PLC3B<0.01,PBeclin-1<0.05,Pp62<0.05,and Pm-TOR<0.05).Compared with those in the RA+CD group,the mRNA expression levels of PI3KC1,Akt1,mTOR,and p62 in the RA+HM group were significantly higher(PPI3KC1<0.01 and PAkt1,mTOR,and p62<0.05),while those of LC3B were significantly lower(P<0.05).Compared with the RA+CD group,the RA+HM group exhibited significantly higher PI3KC1,p-Akt1,and pmTOR protein levels(PPI3KC1<0.01,Pp-Akt1<0.05,and Pp-mTOR<0.01),a higher p62 protein level(P=0.057),and significantly lower LC3B and Vps34 protein levels(P<0.01 for both)in colon tissue.CONCLUSION HM can activate PI3KC1/Akt1/mTOR signaling while inhibiting the PI3KC3(Vps34)-Beclin-1 protein complex in the colon tissues of CD rats,thereby inhibiting overactivated autophagy and thus exerting a therapeutic effect.

文摘Objective:This study was conducted to explore the mechanism of intestinal inflammation and barrier repair in Crohn’s disease(CD)regulated by moxibustion through bile acid(BA)enterohepatic circulation and intestinal farnesoid X receptor(FXR).Methods:Sprague-Dawley rats were randomly divided into control group,CD model group,mild moxibustion group and herb-partitioned moxibustion group.CD model rats induced by 2,4,6-trinitrobenzene sulfonic acid were treated with mild moxibustion or herb-partitioned moxibustion at Tianshu(ST25)and Qihai(CV6).The changes in CD symptoms were rated according to the disease activity index score,the serum and colon tissues of rats were collected,and the pathological changes in colon tissues were observed via histopathology.Western blot,immunohistochemistry(IHC)and immunofluorescence were used to evaluate the improvement of moxibustion on intestinal inflammation and mucosal barrier in CD by the BA-FXR pathway.Results:Mild moxibustion and herb-partitioned moxibustion improved the symptoms of CD,inhibited inflammation and repaired mucosal damage to the colon in CD rats.Meanwhile,moxibustion could improve the abnormal expression of BA in the colon,liver and serum,downregulate the expression of interferon-γand upregulate the expression of FXR mRNA,and inhibit Toll-like receptor 4(TLR4)and myeloid differentiation factor 88(MyD88)mRNA.The IHC results showed that moxibustion could upregulate the expression of FXR and mucin2 and inhibit TLR4 expression.Western blot showed that moxibustion inhibited the protein expression of TLR4 and MyD88 and upregulated the expression of FXR.Immunofluorescence image analysis showed that moxibustion increased the colocalization sites and intensity of FXR with TLR4 or nuclear factor-κB p65.In particular,herb-partitioned moxibustion has more advantages in improving BA and upregulating FXR and TLR4 in the colon.Conclusion:Mild moxibustion and herb-partitioned moxibustion can improve CD by regulating the enterohepatic circulation stability of BA,activating colonic FXR,regulating the TLR4/MyD88 pathway,inhibiting intestinal inflammation and repairing the intestinal mucosal barrier.Herb-partitioned moxibustion seems to have more advantages in regulating BA enterohepatic circulation and FXR activation.Please cite this article as:Shen JC,Qi Q,Han D,Lu Y,Huang R,Zhu Y,Zhang LS,Qin XD,Zhang F,Wu HG,Liu HR.Moxibustion improves experimental colitis in rats with Crohn’s disease by regulating bile acid enterohepatic circulation and intestinal farnesoid X receptor.J Integr Med.2023;21(2):194–204.

文摘AIM: To investigate the effect of moxibustion on intestinal flora and release of interleukin-12 (IL-12) and tumor necrosis factor-α (TNF-α) from the colon in rat with ulcerative colitis (UC). METHODS: A rat model of UC was established by local stimulation of the intestine with supernatant from colonic contents harvested from human UC patients. A total of 40 male Sprague-Dawley rats were randomly divided into the following groups: normal (sham), model (UC), herb-partition moxibustion (HPM-treated), and positive control sulfasalazine (SA-treated). Rats treated with HPM received HPM at acupuncture points ST25 and RN6, once a day for 15 min, for a total of 8 d. Rats in the SA group were perfused with SA twice a day for 8 d. The colonic histopathology was observed by hematoxylin-eosin. The levels of intestinal flora, including Bifidobacterium, Lactobacillus, Escherichia coli (E. coli), and Bacteroides fragilis (B. fragilis), were tested by real-time quantitative polymerase chain reaction to detect bacterial 16S rRNA/DNA in order to determine DNA copy numbers of each specific species. Immunohistochemical assays were used to observe the expression of TNF-α and IL-12 in the rat colons. RESULTS: HPM treatment inhibited immunopathology in colonic tissues of UC rats; the general morphological score and the immunopathological score were significantly decreased in the HPM and SA groups compared with the model group [3.5 (2.0-4.0), 3.0 (1.5-3.5) vs 6.0 (5.5-7.0), P < 0.05 for the general morphological score, and 3.00 (2.00-3.50), 3.00 (2.50-3.50) vs 5.00 (4.50-5.50), P < 0.01 for the immunopathological score]. As measured by DNA copy number, we found that Bifidobacterium and Lactobacillus, which are associated with a healthy colon, were significantly higher in the HPM and SA groups than in the model group (1.395 ± 1.339, 1.461 ± 1.152 vs 0.045 ± 0.036, P < 0.01 for Bifidobacterium, and 0.395 ± 0.325, 0.851 ± 0.651 vs 0.0015 ± 0.0014, P < 0.01 for Lactobacillus). On the other hand, E. coli and B. fragilis, which are associated with an inflamed colon, were significantly lower in the HPM and SA groups than in the model group (0.244 ± 0.107, 0.628 ± 0.257 vs 1.691 ± 0.683, P < 0.01 for E. coli, and 0.351 ± 0.181, 0.416 ± 0.329 vs 1.285 ± 1.039, P < 0.01 for B. fragilis). The expression of TNF-α and IL-12 was decreased after HPM and SA treatment as compared to UC model alone (4970.81 ± 959.78, 6635.45 ± 1135.16 vs 12333.81 ± 680.79, P < 0.01 for TNF-α, and 5528.75 ± 1245.72, 7477.38 ± 1259.16 vs 12550.29 ± 1973.30, P < 0.01 for IL-12). CONCLUSION: HPM treatment can regulate intestinal flora and inhibit the expression of TNF-α and IL-12 in the colon tissues of UC rats, indicating that HPM can improve colonic immune response.

文摘In sulfide-based all-solid-state lithium batteries(ASLBs),the development of high-capacity anode materials with stable interfaces to sulfide solid-state electrolytes(SSEs)is critical.Here,In_(2)O_(3)is explored as an anode material for ASLBs for the first time,demonstrating exceptional interfacial stability and electrochemical performance.The In_(2)O_(3)anode,with a substantial mass loading of 7.64 mg cm^(-2),sustains a charge-specific capacity of528.0 mAh g^(-1)(4.03 mAh cm^(-2))at a current density of0.76 mA cm^(-2)over 500 cycles,with a capacity retention of 81.2%.Additionally,it exhibits remarkable long-term cycling stability(2900 cycles)under a high current density of 3.82 mA cm^(-2),with an exceptionally low decay rate of0.016%per cycle.The charge-discharge mechanism of the In_(2)O_(3)anode is elucidated in detail,revealing that the electrochemical evolution of In_(2)O_(3)in ASLBs involves notonly the alloying/dealloying process of indium(In)but also a conversion reaction between In and Li_(2)O.Notably,as cycling progresses,the conversion reaction of In and Li_(2)O diminishes,with the reversible alloy ing/dealloy ing process becoming predominant.This work offers valuable insights for advancing oxide anode materials in sulfide-based ASLBs.

文摘The clinical efficacy of acupuncture-moxibustion(AM)mainly depends on acupoints,but the relationship between the acupoints and AM remains unclear.Improving clinical efficacy and clarifying the mechanisms of AM is critical.We found that the specificity and sensitivity of acupoints,the skill of operation,and reasonable amount of stimulation can significantly improve the efficacy of AM.In addition,some studies have shown that Neural-Endocrine-Immune network and metabolites are involved in this process,clarifying the therapeutic mechanism of acupoints.Therefore,how to effectively use acupoints to improve the clinical efficacy of AM is one of the key issues in need of an urgent solution.In summary,this article reviewed the Chinese and English databases on the clinical efficacy and underlying mechanisms of acupoints to clarify the relationship between acupoints and AM efficacy and ultimately improve clinical efficacy through effective and rational use of acupoints.
