Based on the theory that "the liver governs the defensive qi"， it is believed that an imbalance in liver qi， leading to abnormalities in the generation， distribution， and circulation of defensive qi， constitutes the core pathogenesis of primary hyperhidrosis. The progression can be summarized as follows， emotional distress， leads to liver constraint， qi stagnation， and impaired liver regulation， resulting in abnormal distribution of defensive qi； qi constraint transforms into fire， leading to hyperactive liver fire， and causing the defensive qi to float upward and fail to be contained； yin-blood depletion and hidden consumption， together with， deficiency of the liver body， result in insufficient generation and upward movement of defensive qi. Treatment should align with the nature and functions of the liver. Xiaochaihu Decoction （小柴胡汤） is used to soothe the liver and regulate qi. Longdan Xiegan Decoction （龙胆泻肝汤） combined with Danzhi Xiaoyao Powder （丹栀逍遥散） is applied to clear the liver and drain fire. Suanzaoren Decoction （酸枣仁汤） combined with Yupingfeng Powder （玉屏风散） is prescribed to nourish blood， enrich the liver， tonify qi and promote the ascending movement of liver qi. In addition， verbal counseling is needed to help patients resolving emotional distress.

Objective To investigate the protective effects of remimazolam(Remi),a novel benzodiazepine sedative,on intestinal barrier function in septic mice.Methods A mouse model of sepsis was established using cecal ligation and puncture(CLP).A total of 96 SPF-grade adult male C57BL/6 mice were randomized into sham operation(Sham),sepsis(Sepsis),and sepsis with Remi intervention(Sepsis+Remi)groups.Survival rate and survival time were recorded within 72 h after modeling.Intestinal pathological alterations,barrier functional indicators,ZO-1 expression,and macrophage polarization status were observed and detected to evaluate the effects of Remi.Lipopolysaccharide(LPS)was used to treat RAW264.7 cells for 24 h to simulate in vitro sepsis model.The cells were divided into control(Control),LPS,and LPS+Remi groups.Immunofluorescence staining was performed to assess macrophage phenotype,mitochondrial morphology,and mitochondrial reactive oxygen species(MtROS),and Western blotting was applied to detect the protein expression of iNOS and CD206.Results Compared with the sepsis group,Remi intervention significantly improved the survival rate of septic mice from 12.50%to 68.75%and markedly prolonged survival duration(P<0.05).Histopathological analysis demonstrated partial restoration of intestinal villus architecture,accompanied with attenuated interstitial edema and reduced inflammatory cell infiltration after Remi intervention.Furthermore,the intervention group demonstrated significant improvement in functional indicators.Both in vivo and in vitro experiments demonstrated elevated iNOS and decreased CD206 expression in the septic mice and LPS-stimulated macrophages(P<0.05),which were partially reversed after Remi intervention.Furthermore,LPS-stimulated macrophages exhibited fragmented mitochondria and elevated MtROS level,whereas Remi intervention ameliorated these conditions(P<0.05).Conclusion Remi protects intestinal barrier function in septic mice by mitigating mitochondrial dynamics imbalance-induced oxidative damage and ameliorating inflammatory macrophage activation.

Objective To explore the protective effect of L-carnitine on myocardial systolic dysfunction in sepsis and its underlying mechanism.Methods A mouse sepsis model was established by cecal ligation and puncture(CLP).Ten-week-old male SPF-grade C57BL/6 mice(body weight 20～30 g)were randomly divided into 5 groups via random number table:Sham group,Sepsis group,L-carnitine group,L-carnitine+Etomoxir(Eto)group,and Eto group.Echocardiography assessed cardiac function,ELISA measured serum creatine kinase isoenzyme MB(CK-MB)levels,and 72-hour survival rates were recorded to evaluate L-carnitine's effects on cardiac function.Cardiomyocytes were isolated,and a cell microtensiometer was used to detect cardiomyocyte contractile function and calcium transients.Myocardial tissues were collected from each group,and ELISA was used to determine the contents of triglyceride(TG),free fatty acid(FFA),and adenosine triphosphate(ATP).An in vitro sepsis model was constructed by stimulating HL-1 cardiomyocytes with lipopolysaccharide(LPS)for 12 hours,which was divided into 5 groups:control(CTRL)group,LPS group,L-carnitine group,L-carnitine+Eto group,and Eto group.ELISA was used to detect the contents of TG,FFA,and ATP as well as the activity of carnitine palmitoyltransferase 1A(CPT1A)in cardiomyocytes.A cellular energy metabolism analysis system was employed to measure fatty acid oxidation capacity,and Western blot was used to detect the protein expression of CPT1A in cardiomyocytes.BODIPY-FL-C16(green fluorescently labeled palmitic acid)was utilized to detect the distribution of fatty acids in the cytoplasm and mitochondria via immunofluorescence technology,thereby observing the ability of cells to transport fatty acids into mitochondria.Results Compared with the Sham group,cardiac function was significantly impaired in the Sepsis group,as evidenced by decreased ejection fraction and mean arterial pressure(P<0.05),along with elevated levels of the cardiac injury marker CK-MB(P<0.05).Treatment with L-carnitine significantly improved myocardial function,restored blood pressure in septic mice,and increased their survival rate from 12.50%to 81.25%(P<0.05).Compared with the Sham group,the contractile function and calcium transients of acutely isolated single cardiomyocytes were significantly reduced in the Sepsis group(P<0.05),while L-carnitine treatment remarkably restored the contractile function and calcium release capacity of septic cardiomyocytes(P<0.05).Both in vivo and in vitro experiments showed that TG and FFA levels were significantly increased(P<0.05),and ATP levels was significantly decreased(P<0.05)in the Sepsis and LPS groups—effects significantly reversed by L-carnitine treatment.Compared with the CTRL group,the basal oxidation rate and maximum oxidation capacity of fatty acids in cardiomyocytes of the LPS group were significantly reduced(P<0.05),and L-carnitine treatment notably improved these indicators.Compared with the CTRL group,the expression and activity of CPT1A in cardiomyocytes of the LPS group were significantly decreased(P<0.05),while L-carnitine treatment significantly increased the expression and activity of CPT1A(P<0.05).In LPS group cardiomyocytes,green fluorescently labeled palmitic acid primarily formed numerous granular/clumpy aggregates in the cytoplasm with minimal mitochondrial colocalization.In the L-carnitine group,the green fluorescent granules in the cytoplasm of cardiomyocytes were smaller,and colocalization with mitochondria was increased.However,the L-carnitine+Eto group exhibited similar phenomena to the LPS group.In addition,both in vivo and in vitro experiments demonstrated that treatment with the CPT1A inhibitor Eto reversed the effect of L-carnitine.Compared with the L-carnitine group,the ATP content in the L-carnitine+Eto group was significantly decreased(P<0.05),while the FFA content was significantly increased(P<0.05).Conclusion L-carnitine facilitates fatty acid entry into mitochondria for β-oxidation via a CPT1A-dependent mechanism,thereby ameliorating fatty acid oxidation dysfunction in septic cardiomyocytes and improving myocardial contractile function.

AIM:This study aims to investigate the effects of aerobic exercise on hypothalamic autophagy and central leptin resistance in obese mice,and to explore the potential mechanisms.METHODS:Forty male C57BL/6J mice,aged 7 to 8 weeks,were randomly assigned to 5 groups:normal control(CON)group,high-fat diet(HFD)group,HFD+exercise(HFD+Exe)group,HFD+phosphate-buffered saline(PBS)group,and HFD+rilmenidine(autophagy ago-nist)group,with 8 mice in each group.Additionally,twelve fibronectin type Ⅲ domain-containing protein 5(Fndc5)gene(encoding irisin precursor protein)knockout(Fndc5 KO)mice were randomly allocated to Fndc5 KO+HFD group and Fndc5 KO+HFD+Exe group,with 6 mice in each group.All mice were fed for 28 weeks.The mice in CON group re-ceived a normal diet,while those in the remaining groups were provided with an HFD.The mice in HFD+Exe and Fndc5 KO+HFD+Exe groups engaged in aerobic treadmill exercise while continuing an HFD from weeks 17 to 28.The mice in HFD+PBS group received intraperitoneal injections of PBS as a control,while those in HFD+rilmenidine group received in-traperitoneal injections of rilmenidine(10 mg?kg-1?d-1),4 times a week over a total duration of 12 weeks(weeks 17 to 28).Following the intervention,serum metabolite levels,as well as concentrations of leptin and irisin,were quantified by ELISA.Morphological alterations in the liver and white adipose tissues were evaluated through oil red O staining and he-matoxylin-eosin(HE)staining.Western blot was utilized to assess the hypothalamic protein levels of autophagy markers,autophagy-related protein 7(ATG7),beclin-1,microtubule-associated protein 1 light chain 3(LC3)and p62,and leptin resistance markers,suppressor of cytokine signaling 3(SOCS3)and protein tyrosine phosphatase 1B(PTP1B).RE-SULTS:Observations of mouse phenotypes indicated that HFD feeding significantly increased body weight,blood lipid content and serum leptin level(P<0.05).The results of HE and oil red O staining demonstrated that HFD feeding marked-ly promoted lipid accumulation in the liver and caused ballooning of white adipocytes.Western blot analyses revealed that HFD feeding significantly down-regulated the protein levels of ATG7,beclin-1 and LC3-Ⅱ/LC3-I,but up-regulated the pro-tein level of p62(P<0.05),thus reducing cellular autophagy capacity.Furthermore,HFD feeding elevated the protein levels of leptin resistance markers SOCS3 and PTP1B(P<0.05).Aerobic exercise and autophagy agonist were found to partially reverse these changes,enhancing cellular autophagy capacity and alleviating leptin resistance.However,these effects were diminished after knockout of Fndc5 gene,further substantiating the role of irisin in exercise-mediated en-hancement of cellular autophagy and attenuation of leptin resistance.CONCLUSION:Aerobic exercise alleviates hypo-thalamic autophagy defect and central leptin resistance in obese mice,which may be associated with exercise-induced irisin.

Aimed to find a safe and effective drug to replace nitroimidazole drugs in aquaculture pro-duction for the prevention and treatment of Trichomoniasis in pigeons,which can improve the eco-nomic benefits of meat pigeon breeding and ensure food safety.Firstly,Trichomonas was isolated and cultured from the crop of diseased pigeons and identified.After stable passage,a quantitative method for in vitro detection of Trichomonas was established by combining an automated cell counter and quantitative real-time PCR technology.To prepared the drug,powders of Sophora fla-vescent and Philodendron were made into herbal water extracts(SFPA)and mixed with copper sulfate(CS)solution.Then added the drug to the culture medium of Trichomonas to determine the effective concentration of it.A total of 135 pairs each of Silver King and Mimas breeding pigeons in the same laying period were selected and randomly divided into three groups,with 6 replicates in each group and 15 pairs of breeding pigeons in each replicate.Four days before brooding,the three groups were fed with 200 mL of pure water,0.5 g/L metronidazole(MDZ)solution,and a mixed solution of 30 g/L SFPA and 0.5 g/L CS,respectively.The feeding experiment lasted for 26 d.Results showed that the mixed solution of SFPA and CS had a significant killing effect on Trichomonas in vitro(P＜0.05).Feeding the drug to breeding pigeons significantly reduced the in-fection rate of breeding pigeons by Trichomonas(P＜0.05).The drug had no significant effect on the serum biochemical indexes,antioxidant properties,immunoglobulin levels of breeding pigeons,the average cage weight,immune organ indexes,meat quality and slaughter performance of squabs(P＞0.05).The results suggested that adding SFPA and CS to pigeons can effectively prevent and treat Trichomoniasis and improve production performance.It can replace nitroimidazole drugs without affecting the immune level of breeding pigeons and the weight,immune level,slaughter performance and meat quality of squabs,thereby reduce drug residues in poultry products and en-hance the food safety.

AIM:To study the protective effect of transient receptor potential vanilic acid subtype 1(TRPV1)agonist capsaicin(CAP)on traumatic blood loss shock rats,and to further explore its possible mechanism by network pharmacology.METHODS:Forty-five SD rats were divided into 5 groups by random number table method:normal group,shock group,lactated Ringer's solution(LR)group,CAP pretreatment(single administration before shock)group,CAP pre-final administration(twice administration before and after shock)group,with 9 rats in each group for survival observation.Then 32 SD rats were divided into 4 groups according to the results of survival experiment:normal group,shock group,LR group,CAP pre-final administration group,with 8 rats in each group for blood pressure,hemodynamics,arterial blood gas,vascular reactivi-ty and hepaticand renal blood flow.At the same time,the potential mechanism of CAP in the treat-ment of traumatic hemorrhagic shock was investi-gated by network pharmacology.Furthermore,ap-ply the dataset to validate and analyse the diagnos-tic value of the hub genes.RESULTS:Rats in shock group died within hours of the completion of the shock model,and the mean survival time was 1.25(0.42,6.21)h.LR resuscitation could improve the survival of rats to some extent.The survival rate and survival time of rats in the CAP pretreatment group were slightly increased as compared with the LR group,while twice administration of CAP be-fore and after shock(CAP pre-final administration)resulted in better outcomes than LR resuscitation alone.Further results indicated that CAP pre-final administration significantly reduced the blood lac-tic acid level,improved the vasoconstrictive and di-astolic reactivity,and increased the liver and kidney blood flow of shock rats as compared with LR group.The improvement of hemodynamics and blood gas indexes in CAP group was slightly higher than LR group,but there was no statistical signifi-cance.A total of 37 genes related to CAP anti-trau-matic hemorrhage shock were obtained by net-work pharmacology.KEGG enrichment analysis showed that the Ca ion signaling pathway and Ras signaling pathway were significantly enriched.Vali-dation of the dataset showed that the expression levels of CXCR4,NF-kB1,GFPA and NTF3 hub gene were significantly different in the normal and shock groups,and that CXCR4 has a high diagnostic value for traumatic haemorrhagic shock.CONCLUSIONS:CAP,the TRPV1 agonist,significantly improved vas-cular function,increased organ blood flow,and cor-rected the lactic acidosis in rats with traumatic hemorrhagic shock,thus markedly improved the survival outcomes.The mechanism may be related to Ca ion signal pathway and Ras signal pathway.CXCR4,NF-kB1,GFPA and NTF3 may be having an important role in it.

Objective To establish a multi-state Markov model of systemic lupus erythematosus(SLE)for patients in China and to explore the transition rule of organ damage accumulation and possible factors affecting the transition between states.Methods A retrospective cohort study was conducted using the data from CSTAR.The Systemic Lu-pus International Collaborating Clinics/American College of Rheumatology Damage Index(SDI)was divided into five irreversible disease states(SDI=0,1,2,≥3,and death,marked as S0,S1,S2,S3,Death).The R"mstate"package was used for statistical analysis.Results This study included 23 926 cases of SLE patients with cumulative follow-up of 12 030 visits.Among these patients,21 070 patients had no any organ damage at baseline.At the follow-up period,the transition probabilities of organ damage of S0→S1,S1→S2,S2→S3,S3→Death were 7.01％,12.58％,10.64％,and 12.19％,respectively.The multi-state Markov model showed that age,gender,disease dura-tion,SLEDAI score,corticosteroid dosage,and involvement of major organs were associated with the transition of or-gan damage status,each 1 year increased was associated with a 2％～3％increase in risk of damage accumulation risk(P＜0.01).Also,neurological(S0→S 1:HR=1.34;S1 →S2:HR=1.53;S2→S3:HR=1.73),cardiopulmonary(S0→S1:HR=3.66;S 1→S2:HR=1.51;S2→S3:HR=1.52),renal(S0→S 1:HR=1.24)and hematological involvement(S0→S1:HR=1.24)might be the risk factors.Conclusions The probability of organ damage accumulation in SLE pa-tients increases over time.Therefore,in the early stage of the disease,the involvement of important organs needs to be minimized and the treatment strategy should be dynamically adjusted at different stages of treatment.
