Hepatolenticular degeneration， also known as Wilson disease （WD）， is a hereditary disease caused by mutations in the ATP7B gene， leading to copper metabolism disorders. Gene mutations result in impaired synthesis of copper-binding protein， and abnormal excretion of copper through bile leads to pathological deposition of copper in various organs， ultimately causing multi-organ damage. The insidious onset and low specificity of symptoms make it difficult to diagnose this disease. On the basis of existing studies and the theory of latent toxin， this paper proposes that latent toxin in kidney collaterals is the main pathogenesis of renal injury in WD. It is pointed out that health Qi deficiency and latent pathogen are the premises for the occurrence of this disease， and the transformation of latent pathogen into toxin is the ley pathological process. Toxin damaging kidney collaterals is the ultimate result. According to the pathogenesis， this paper proposes the treatment principle of reinforcing healthy Qi and resolving toxin and treatment based on syndrome differentiation. This review provides new ideas for the diagnosis and treatment of renal injury in WD with traditional Chinese medicine.

As the third-level diagnosis of migraine， recurrent gastrointestinal disturbance is a group of disorders with recurrent episodic attacks of abdominal pain and/or discomfort and nausea and/or vomiting that may be associated with migraine， and it is a clinical syndrome with the core symptom of abdominal pain， with the presence of clinical and neurobiological associations. This article reviews the similarities of the two diseases from the aspects of epidemiological characteristics， gender distribution tendency， clinical course， auxiliary examination， and treatment response， as well as three potential mechanisms in pathophysiology. This strong association between functional recurrent abdominal pain and migraine suggests that although there is no definitive evidence， adult functional recurrent abdominal pain， or at least its specific subsets， may belong to the spectrum of migraine. In other words， functional recurrent abdominal pain itself without headache may be a “migraine phenomenon”. In the future， it is necessary to conduct more rigorously designed observational studies on the association between the two diseases to clarify such possibility， in order to provide strong supporting evidence for the diagnosis and treatment of patients with functional recurrent abdominal pain and migraine and relieve pain as soon as possible.

Glucagon-like peptide-1 ( GLP-1 ) is secreted by gut enteroendocrine cells. GLP-1 receptor agonists ( GLP-1 RAs) control glucose-related augmentation of insulin and suppress glu-cagon secretion. GLP-lRAs also inhibit gastric emptying, food intake and limit weight gain. In the past decade, significant progresses have been made in the investigation on the effects of GLP-1 RAs on cardiovascular system. The potential advantages of oral small-molecule GLP-1 RAs could improve the application of this class of drugs. This review highlights the multiple cardiovascular profiles of GLP-1 RAs in the treatment of cardiovascular diseases to provide new insights into cardiovascular benefits of GLP-1 RAs.

Objective To explore the clinical significance of nucleolar antinuclear antibodies(ANA)in re-lated diseases.Methods This study was a retrospective study.Clinical samples of 71780 patients who visited the hospital from January 2017 to May 2022 were collected.Indirect immunofluorescence was used to detect ANA in clinical samples.Statistical analysis was conducted on the positivity rate of nucleolar ANA in clinical patients,as well as the relevant clinical information and laboratory characteristics of patients with autoimmune diseases(AID)with nucleolar ANA positivity.Results Among 71780 patients who underwent routine ANA testing,16778 were positive for ANA,with a positive rate of 23.37％.Among them,there were 1 708 cases of nucleolar type,accounting for 2.38％of all routine ANA tests,and the proportion of ANA positive cases was 10.18％.There was a statistically significant difference in the positive rate of nucleolar ANA between patients of different genders in the＞20-＜50 year old group and the ≥ 50 year old group(P＜0.05),while there was no statistically significant difference in the positive rate of nucleolar ANA between patients of different genders in the ≤ 20 year old group(P＞0.05).There was a statistically significant difference in the positivity rate of nucleolar ANA among women of different age groups(P＜0.05),among them,the highest positive rate of nucleolar ANA was found in women aged between 20 and 50 years old.There was no statistically significant difference in the positive rate of nucleolar ANA among males of different age groups(P＞0.05).The positivi-ty rate of ANA was the highest among patients in the Department of Rheumatology and Immunology(70.35％),but nucleolar ANA positivity was mainly seen in departments such as Reproductive Medicine Cen-ter(12.90％),Respiratory Medicine(12.40％),and Neurology(11.29％),and the difference in positivity rates between departments was statistically significant(P＜0.05).Out of 1 708 nucleolar ANA positive indi-viduals,420 underwent ANA titers,including 34 AID patients and 386 non AID patients.There was no statis-tically significant difference in nucleolus positive titers between non AID patients and AID patients(P＞0.05).Conclusion The nucleolus type is a common fluorescence pattern in ANA positive individuals,and there are gender and age differences in ANA positive individuals.The positive rate and titer of nucleolar ANA vary among different AID diseases.Combined with other immune function indicators,and it is helpful for early differential diagnosis of AID.

Objective To clarify the anti-inflammatory effect of chlorogenic acid on lipopolysaccharide(LPS)-induced inflamma-tion in macrophage RAW264.7,and to reveal its possible molecular mechanism.Methods The cellular activity of RAW264.7 after the intervention of different concentrations of chlorogenic acid was detected by CCK-8 method;the macrophage RAW264.7 was stimulated by LPS to preset cellular inflammatory state.The blank control group(K group,n=3),the model control group(L group,n=3),and the experimental group(S group,n=3)were administered separately,and the cell morphology was dynamically observed;cell precipita-tion and supernatants were obtained at 24 h and 48h,respectively.The concentrations of inflammatory cytokine interleukin(IL)-1β,monocyte chemoattractant protein-1(MCP-1),and arginase-1(Arg-1)in the cell supernatants were detected by enzyme-linked immunosorbent assay(ELISA);the mRNA expression of prostaglandin endoperoxide synthase 2(PTGS2),transforming growth factor-β1(TGF-β1),high mobility histone 1(HMGB1),and nuclear transcription factor-κB(NF-κB)were detected by quantitative real-time PCR(RT-qPCR).Results RAW264.7 cellular inflammatory state was successfully preset with 1 μg/ml LPS;12.5～200.0μg/ml chlorogenic acid had no distinct toxicity on RAW264.7.Chlorogenic acid at 50μg/ml and 200μg/ml had obvious proliferation effects on RAW264.7 cells(P＜0.05).Compared with the model control group,the content of IL-1 β protein in the supernatant of the experimental group was significantly decreased,while the content of Arg-1 was significantly increased(P＜0.05).Compared with the model control group,50μg/ml of chlorogenic acid significantly decreased the mRNA expressions of NF-κB,TGF-β1,PTGS2,and HMGB1 in LPS-induced inflammatory cells(P＜0.05).Conclusion Chlorogenic acid has a distinct inhibitory effect on LPS-induced RAW264.7 inflammatory response,which may be achieved by regulating molecular expression of the HMGB1-mediated NF-κB pathway.

OBJECTIVE To explore the renal protective mechanism of Shenbining granules on IgA nephropathy （IgAN） rats based on mitochondrial quality control system. METHODS IgAN rat model was established by the method of “bovine serum albumin+carbon tetrachloride+lipopolysaccharide”. The model rats were randomly divided into model group， prednisone acetate group （6.25 mg/kg）， Shenbining equal-dose group （4.1 g/kg） and Shenbining high-dose group （20.5 g/kg）. The normal rats were taken as the normal control group， with 12 rats in each group. Rats were given corresponding drugs or distilled water intragastrically in each group， once a day， for 4 consecutive weeks. After the last medication， the 24 h total urinary protein （24 h- UTP） and erythrocyte count in urine were determined， and the levels of serum creatinine （Scr）， blood urea nitrogen （BUN）， albumin （ALB） and alanine transaminase （ALT） were also detected. The histopathological changes in the kidneys and changes in IgA deposition in the mesangial area of the kidney were observed. mRNA and protein expression levels of PTEN-induced putative kinase 1 （PINK1）， E3 ubiquitin ligase（Parkin）， microtubule-associated protein 1 light chain-3 （LC3）， dynamin-related protein 1 （Drp1） and mitofusin 2 （Mfn2） were detected in the kidney tissues of rats. RESULTS Compared with model group， 24 h-UTP， urinary erythrocyte count， ALT， BUN and Scr levels， LC3-Ⅱ/LC3-Ⅰ mRNA ratio， mRNA and protein expressions of Drp1 were reduced significantly in prednisone acetate group， Shenbining equal-dose group and Shenbining high-dose group （P＜0.05）； ALB level， LC3-Ⅱ/LC3-Ⅰ protein ratio， mRNA and protein expressions of PINK1， Parkin and Mfn2 were increased significantly （P＜0.05）； the pathological morphology of kidney tissue in rats was significantly improved， and IgA deposition was significantly reduced. CONCLUSIONS Shenbining granule may reduce renal pathological injury in IgAN rats and protect renal function by activating the PINK1/Parkin pathway， enhancing mitochondrial autophagy， and correcting mitochondrial kinetic disorders.

Objective: To analyze the effects of 12week highintensity fitness exercise on body composition,lipid metabolism and gut microbiota in obese adolescents, so as to provide references for improving the health levels of obese adolescents. Methods: From January to June 2023, 20 obese adolescents from Huaifeng Vocational and Technical School in Huaian City were recruited for the study. Participants were assigned to an exercise group (n=10) and a control group (n=10) for a 12week exercise intervention by random number table method, and both groups had the same diet during the intervention period. The exercise group engaged in three exercises every week, mainly consisting of moderate to highintensity aerobic exercise combined with highintensity intervals. In the first week, there was a 30 minutes of aerobic exercise, followed by 10 minutes of highintensity interval training in the total intervention time each week, and the rest of the time was aerobic exercise with a total intervention time of 60 minutes to maintain; the control group did not receive specific interventions. Body composition was measured using bioelectrical impedance analysis, and lipid levels were determined using an automatic biochemical analyzer. The expression levels of serum inflammatory factors were measured at baseline and after 12 weeks of intervention, and gut microbiota was analyzed using 16S rRNA gene sequencing. Statistical analysis was performed using t test and Chisquare test. Results: After 12 weeks of intervention, the levels of triglycerides (TG), and lowdensity lipoprotein cholesterol (LDL-C) in obese adolescents in the exercise group decreased from (1.7±0.6, 3.5±0.8) mmol/L to (0.9±0.3, 2.6±0.4) mmol/L, while highdensity lipoprotein cholesterol (HDL-C) increased from (1.1±0.2) mmol/L to (1.4±0.2) mmol/L; and serum interleukin-1 receptor antagonist(IL-1Rn) decreased from (8.4±1.6) to (4.5±0.4) ng/mL in the exercise group (t=7.34,2.49,-3.05,2.56, P<0.05). The α-diversity results showed that the Chao index (268.00±22.67) and Ace index (243.98±38.64) in the exercise group were higher than those in the control group (184.52±19.28, 171.43±23.33), and the differences were statistically significant (t=2.48, 2.53, P<0.05). The Shannon index (5.36±1.41) in the exercise group was higher than that in the control group (4.73±1.12), and the Simpson index (0.78±0.10) was lower than that in the control group (0.89±0.10), but the differences were not statistically significant (t=1.83, -2.10, P>0.05). The β-diversity results showed that the intergroup differences in gut microbiota structure between the exercise group and the control group were greater than the intragroup differences, and the differences in gut microbiota structure between the exercise group and the control group were statistically significant (R2=0.083，P<0.05). After intervention, there were significant differences in the relative abundances at the levels of phylum, class, genus, and species in gut microbiota among obese adolescents between the exercise group and the control group (P<0.05). Conclusion The 12week highintensity fitness exercise can alleviate obesity symptoms in obese adolescents through the gut microbiota-lipid metabolism pathway and improve mild chronic inflammatory status.
