Bladder tumor within inguinal bladder hernia is rare. This article reports a case of a male patient who was admitted to hospital due to gross hematuria，accompanied by lower abdominal pain when straining to urinate for two months. Physical examination revealed a irreducible mass in the left inguinal region. Ultrasound and MRI examinations suggested an inguinal bladder hernia complicated by multiple bladder lesions. Cystoscopy revealed extensive tumors，and pathological examination indicated high-grade urothelial carcinoma with carcinoma in situ. PET-CT confirmed pelvic lymph node metastasis. The patient underwent three cycles of neoadjuvant therapy followed by laparoscopic radical cystectomy combined with hernia repair. There was no evidence of recurrence of the hernia or tumor after one year of follow-up.

[Objective]To summarize the distribution characteristics and mutual combination rules of syndrome elements through the extraction of syndrome elements from recent literature on recurrent oral ulcers,analyze the etiology and pathogenesis and provide theoretical basis for clinical diagnosis and treatment in traditional Chinese medicine.[Methods]The clinical literature related to recurrent oral ulcers in the past four years in the China National Knowledge Infrastructure and WanFang databases was searched,key information such as syndromes and syndrome elements was extracted,an information database was established,and frequency analysis was conducted.[Results]One hundred and sixty-one literatures were included,and 26 standard Chinese medicine syndromes for recurrent oral ulcers were extracted.Heart-spleen heat accumulation syndrome was the most common,followed by Yin deficiency and fire hyperactivity syndrome,dampness-heat due to spleen deficiency syndrome,phlegm and blood stasis were the least common.A total of 8 disease location syndrome elements were extracted from the spleen,heart,stomach,liver,kidney,gallbladder,lung and large intestine.The most common disease location syndrome was the spleen,followed by the heart,and the large intestine was the least frequent.Fourteen disease syndrome elements including heat,blood deficiency,and poison were extracted.The most common was heat,followed by Yin deficiency,and dryness was the least frequent.There were 10 combinations of syndrome elements,among which spleen+heat,heart+spleen+heat,heart+fire were the most frequent,and liver+blood deficiency was the least frequent.[Conclusion]The main type of recurrent oral ulcers is characterized by heart-spleen heat accumulation,which is most closely related to the spleen,the pathological factor is heat.Clinical treatment of recurrent oral ulcers often starts with the three organs of the spleen,heart and stomach,with the three most important methods of reducing fire,clearing heat and eliminating dampness.

Objective To explore the differences in neural activity between patients with anorexia nervosa(AN)and healthy controls(HC),as well as the association between these differences and symptoms in AN patients,using activation likelihood estimation(ALE)meta-analysis.Methods The literature search covered the period from 2000 to March 2025.From a pool of 588 identified studies,4 studies focusing on the neural activity differences between AN patients and HC were selected for inclusion.These studies comprised 106 participants and 21 sets of coordinates.The ALE meta-analysis method was employed,and the GingerALE software was used to systematically analyze the reported brain region changes and their peak coordinates,aiming to investigate the differences in brain functional activity between AN patients and HC.Results Compared to the HC group,AN group showed significantly enhanced activation in the left parahippocampal gyrus/amygdala(ALE value=0.39×10-2),right parahippocampal gyrus/amygdala(ALE value=0.39×10-2)and suboccipital gyrus(ALE value=0.39×10-2),along with a significant reduction in activation in Brodmann area 17(ALE value=0.61×10-2)(P<0.01,FWE corrected).Conclusion Key brain regions in AN patients including the parahippocampal gyrus,inferior occipital gyrus,and amygdala demonstrate significant functional activation abnormalities.

Objective To investigate the correlation between sex hormone-binding globulin(SHBG)and lipid metabolism and visceral fat area(VFA)in male adults with different glucose tolerance.Methods A total of 473 male subjects were enrolled from the outpatient clinic and ward in PLA NO.903 Hospital from January 2018 to December 2020.All the subjects were divided into three groups according to OGTT results:normal glucose tolerance group(NGT,n=179),impaired glucose regulation group(IGR,n=90)and newly diagnosed type 2 diabetes mellitus group(T2DM,n=204).Serum SHBG level,abdominal visceral fat area(VFA)and biochemical indexes were compared among the three groups.Results Compared with NGT group,WC,WHR,BMI,HbA1c,FPG,2 hPG,2 hIns,TG and VFA were increased(P＜0.05),while SHBG was decreased(P＜0.05)in IGR group.WC,SBP,DBP,HbA1c,FPG,2 hPG,2 hIns,HOMA-IR,TG,FFA,VFA and VFA/SFA were increased,while HOMA-β,SHBG were decreased(P＜0.05)in T2DM group.Compared with IGR group,SBP,HbA1c,FPG,2 hPG,2 hIns and HOMA-IR were increased,HOMA-β was decreased in T2DM group(P＜0.05).Pearson correlation analysis showed that SHBG was positively correlated with HDL-C(P＜0.01),but was negatively correlated with WC,WHR,BMI,2 hIns,SUA,TG,VFA and SFA(P＜0.05 or P＜0.01).Multivariable linear regression analysis showed that HDL-C,TG and VFA were the influencing factors for SHBG.Conclusion Serum SHBG is closely related to abdominal obesity and lipid metabolism.Increasing the level of SHBG can reduce visceral fat accumulation and improve IR.

Objective:To investigate the effect of high glucose on the release of interleukin (IL)-1β and IL-18 in placental trophoblast by activating NLRP3 inflammasome.Methods:Gestational diabetes mellitus(GDM) placentas and control placentas were collected and the expression levels of NLRP3 and Caspase-1 were determined. Human placental trophoblast HTR-8/SVneo were cultured and divided into control group(5.5 mmol/L glucose), high glucose group(25 mmol/L glucose), DMSO+ high glucose group, and Ac-YVAD-cmk(NLRP3 inflammasome inhibitor)+ high glucose group. The expression levels of NLRP3 and Caspase-1 in cells as well as the contents of IL-1β and IL-18 in the medium were determined.Results:The expression levels of NLRP3 and Caspase-1 in GDM placenta were higher than those in control placenta( P<0.05) and positively correlated with homeostasis model assessment of insulin resistant index(HOMA-IR) and fasting insulin. The expression levels of NLRP3 and Caspase-1 in HTR-8/SVneo cells and the secretion levels of IL-1β and IL-18 in high glucose group were higher than those in control group( P<0.05). Ac-YVAD-cmk significantly suppressed high glucose-stimulated IL-1β and IL-18 secretion( P<0.05). Conclusion:High glucose promotes the release of IL-1β and IL-18 from placental trophoblast via activating NLRP3 inflammasome.

Objective:To observe the effect of dictyophora polysaccharide (DIP) on PINK1/Parkin pathway mediated mitophagy induced by sodium arsenite (NaAsO 2) in human hepatocytes (L-02 cells). Methods:The L-02 cells in logarithmic growth phase and in good condition were divided into control group, NaAsO 2 group (10 μmol/L), DIP group (80 μg/ml), DIP + NaAsO 2 group (80 μg/ml DIP + 10 μmol/L NaAsO 2) , N-acetylcysteine (NAC) group (5 mmol/L), and NAC + NaAsO 2 group (5 mmol/L NAC + 10 μmol/L NaAsO 2). Western blotting was used to detect the expression levels of mitophagy related proteins p62, microtubule-associated protein 1 light chain 3 (LC3)Ⅱ/LC3Ⅰ, PINK1, and Parkin. The mitochondrial stucture and autophagosomes were observed by transmission electron microscope, the fluorescent probe method was used to detect the expression level of intracellular reactive oxygen species (ROS). Results:Compared with the control group, the protein expressions of p62, LC3 Ⅱ/LC3 Ⅰ, PINK1, and Parkin in NaAsO 2 group were higher ( P < 0.05); compared with the NaAsO 2 group, the protein expressions of p62, LC3 Ⅱ/LC3 Ⅰ, PINK1 and Parkin were lower in DIP, DIP + NaAsO 2, NAC, and NAC + NaAsO 2 groups ( P <0.05). According to the transmission electron microscope, compared with the control group, the mitochondria of L-02 cells in NaAsO 2 group were significantly damaged and the number of autophagosomes increased. Compared with NaAsO 2 group, the degree of mitochondrial swelling, vacuolar degeneration and the number of autophagosomes decreased in DIP + NaAsO 2 group. Compared with the control group (33 110.00 ± 2 191.28), the intracellular ROS level in NaAsO 2 group was higher (48 000.00 ± 2 395.31, P < 0.05); the level of intracellular ROS in DIP + NaAsO 2 group (38 670.00 ± 2 620.56) was significantly lower than that in NaAsO 2 group( P < 0.05), and there was no significant change compared with the control group ( P > 0.05). Conclusions:NaAsO 2 can induce PINK1/Parkin mediated mitophagy in L-02 cells. DIP can alleviate NaAsO 2 induced mitophagy. DIP may affect PINK1/Parkin mediated mitophagy induced by NaAsO 2 through the regulation of ROS.

Objective:To explore the mechanism of apoptosis induced by sodium arsenite (NaAsO 2) in human hepatic cells (L-02) through reactive oxygen species (ROS) accumulation and mitochondrial dysfunction, and provide experimental evidence for the mechanism of arsenic poisoning. Methods:L-02 cells were divided into control group, NaAsO 2 group (10 μmol/L NaAsO 2), N-acetylcysteine (NAC) group (5 mmol/L NAC), and NaAsO 2 + NAC group (10 μmol/L NaAsO 2, 5 mmol/L NAC), and were cultured in vitro for 24 h. The intracellular ROS level, mitochondrial membrane potential depolarization ratio and cell apoptosis rate were measured by dichlorodihydrofluorescein diacetate (DCFH-DA) fluorescence probe, JC-1 staining and Annexin V-FITC/PI double staining, respectively; the mRNA and the protein of Caspase 3, cytochrome C (Cyt-C) and cytochrome C oxidaseⅣ (COXⅣ) were detected by real time fluorescence quantitative PCR (qRT-PCR) and Western blotting, respectively. Results:There were statistically significant differences in intracellular ROS levels (3 857 392.33 ± 44 928.39, 4 515 288.00 ± 32 660.64, 3 670 150.67 ± 101 987.69, 4 035 235.67 ± 99 995.30), mitochondrial membrane potential depolarization ratios (2.16 ± 0.54, 7.95 ± 0.52, 2.70 ± 0.29, 1.01 ± 0.23) and total apoptosis rates (1.45 ± 0.03, 4.27 ± 0.17, 1.87 ± 0.12, 2.52 ± 0.35) between groups ( F = 62.62, 159.81, 112.70, P < 0.05). There were statistically significant differences in Caspase 3, Cyt-C, COXⅣ mRNA expression levels ( F = 9.20, 7.33, 14.87, P < 0.05) and in cleaved-Caspase 3, Cyt-C, COXⅣ protein expression levels( F = 31.42, 8.01, 83.30, P < 0.05) between groups. Compared with the control group, the intracellular ROS level, mitochondrial membrane potential depolarization ratio and total apoptosis rate were significantly increased ( P < 0.05); Caspase3, Cyt-C mRNA and protein expression levels were significantly increased ( P < 0.05), and COXⅣ mRNA and cleaved-Caspase 3, Cyt-C protein expression levels were significantly decreased ( P < 0.05) in NaAsO 2 group. Compared with the NaAsO 2 group, the intracellular ROS level, mitochondrial membrane potential depolarization ratio and total apoptosis rate of NaAsO 2 + NAC group were significantly decreased ( P < 0.05); the Caspase3, Cyt-C mRNA and cleaved-Caspase 3, Cyt-C protein expression levels were significantly decreased ( P < 0.05), the COX Ⅳ mRNA and protein expression levels were significantly increased ( P < 0.05). Conclusions:NaAsO 2 stimulates L-02 cells to produce excessive ROS, which induces mitochondrial depolarization and further triggers mitochondrial damage, resulting in increased release of Cyt-C and activation of the mitochondrial apoptosis pathway that Caspase 3 protein induces apoptosis in L-02 cells, which may be one of the main mechanisms of arsenic-induced liver injury.
