Abstract Postoperative urinary retention is a common complication after mixed hemorrhoid surgery, referring to the inability of urine in the bladder to be normally expelled, leading to urine retention. This condition not only prolongs the postoperative recovery time and increases medical costs, but may also cause problems such as urinary tract infections and bladder dysfunction. The pathogenesis of urinary retention after mixed hemorrhoid surgery is complex, involving multiple factors such as the type of surgery, anesthesia method, individual differences among patients, postoperative pain management and psychological stress. Although there are various clinical treatment methods, their efficacy varies among individuals. This article reviews relevant literature from 2018 to 2024, analyzing the etiology of urinary retention after mixed hemorrhoid surgery. It summarizes the intervention measures and mechanisms of non-pharmacological treatments, such as physical therapy and analgesic techniques, as well as pharmacological treatments, including anticholinesterase drugs, selective α-receptor blockers and analgesics drugs, so as to provide the reference for the prevention and treatment of urinary retention after mixed hemorrhoid surgery.

ObjectiveTo multidimensionally analyze the clinical effects of Qianyang Yuyin granules on elderly hypertensive patients through an "energy-inflammation-aging" network. MethodsRelevant datasets were retrieved from the GEO database. Gene set enrichment analysis （GSEA） was performed on the gene expression profiles of peripheral blood cells from patients with essential hypertension in dataset GSE24752. The GSEA referenced "GO gene sets" and "KEGG gene sets" to identify significantly enriched gene sets. A clinical trial was conducted using a randomized controlled study design. A total of 40 patients meeting the inclusion criteria were enrolled. The control group received standard antihypertensive treatment with angiotensin receptor blockers （ARBs） or combined calcium channel blockers （CCBs）. In contrast，the treatment group received Qianyang Yuyin Granules in addition to the standard treatment for 12 weeks. Blood pressure levels and clinical efficacy were observed，and changes in energy metabolism indicators，DNA damage markers，and senescence-associated secretory phenotype （SASP） in blood were measured using ELISA before and after treatment. ResultsGSEA results indicated significant energy metabolism dysregulation in hypertensive patients. Clinical findings showed that both groups achieved blood pressure control without significant intergroup differences. In terms of clinical efficacy，the treatment group had a significantly higher effective rate compared to the control group （95% vs 65%，P0.05）. After treatment，the treatment group showed a significant increase in NAD⁺ levels （P0.01），with higher levels compared to the control group （P0.05）. The treatment group also exhibited a greater reduction in DNA damage marker 8-OHdG （P0.01） and cell adhesion factors ICAM-1 and VCAM-1 （P0.01） compared to the control group. Pro-inflammatory cytokines IL-1β and IL-6 were significantly reduced in the treatment group （P0.01），with greater reductions compared to the control group （P0.05，P0.01）. Anti-inflammatory cytokines IFN-α，IL-4，and IL-10 were significantly elevated in the treatment group （P0.01），with higher levels compared to the control group （P0.01）. No significant adverse reactions were reported in either group. ConclusionThe "energy- inflammation- aging" network plays an important role in the pathological mechanism of hypertension patients. Qianyang Yuyin granules may delay the aging process by increasing patients' energy metabolism levels，reducing DNA oxidative damage，and maintaining the balance of inflammatory factors.

As a unique gene in the genome,FLASH(FADD-like interleukin-1β-converting enzyme asso-ciated huge protein)/CASP8AP2 is involved in multiple cellular processes,including apoptosis,histone gene pre-mRNA processing,transcriptional regulation,and cell cycle progression.Clinical studies have shown that FLASH is a valuable prognostic marker for acute lymphoblastic leukemia,and a crucial factor for the survival of various cancer cells.Therefore,in-depth research into the function of FLASH may offer new perspectives for the treatment of related diseases.Our previous research identified FLASH as a bind-ing partner of p53,demonstrating that FLASH enhances the transcriptional activity of p53.Here we fur-ther investigate the molecular mechanisms of the interaction between FLASH and p53,revealing that the p53-K386R mutation(SUMOylation residue)attenuated its interaction with FLASH(aa 51-200)and FLASH-SIM(SUMO-interacting motif)(aa 1 534-1 806)significantly.However,SUMO can bind to FLASH-SIM directly,instead of FLASH(aa 51-200).Subsequent research shows that overexpression of FLASH in cells enhances global SUMO1 conjugation and p53-SUMO1 conjugation,therefore providing a plausible explanation for the underlying mechanism of FLASH enhancing the transcriptional activity of p53.Since promyelocytic leukemia protein nuclear body(PML NB)serves as subcellular reactors for SUMO conjugation within the cell,and the PML Ⅳ isoform can specifically enhance the SUMO modifica-tion of p53,we have investigated the interaction between FLASH and PML Ⅳ,and elucidated the struc-tural basis of their interaction:both FLASH-N3A(501-802)and FLASH-C2(1 807-1 981)bind to PML Ⅳ(aa 228-633).Further investigations reveal that they can synergistically enhance global SUMO1 modification as well as SUMO1 modification of p53.The interaction between FLASH and tumor suppres-sors p53 or PML Ⅳ enriches our understanding of its function and reveals the potential mechanism of FLASH in tumor development,therefore offering novel insights into cancer diagnosis and treatment.

This study aimed to investigate halofuginone's inhibitory effect and mechanism on the activity of hepatocellular carcinoma cells. HepG2 cells were used to detect the effects of halofuginone. After treatment, cell activity, cell migration, cell cycle, and cell apoptosis were detected by CCK-8, transwell, and flow cytometry, respectively. The expression levels of growth and metabolism-related factors such as citrate synthase (CS), ketoglutarate dehydrogenase (OGDH), and isocitrate deoxygenase (IDH) were detected by real-time quantitative PCR and Western blot. Compared with the control group, the activity of HepG2 cells was significantly inhibited by halofuginone (P < 0.01), the migration rate of HepG2 cells was decreased (P < 0.01), the apoptosis of HepG2 cells was induced (P < 0.01), and the cell cycle was arrested in S phase (P < 0.01). The expression levels of tricarboxylic acid key enzymes CS, IDH3, and OGDH were up-regulated, the expression level of isocitrate dehydrogenase isoenzymes IDH1 and IDH2 were down-regulation. In conclusion, halofuginone can inhibit the proliferation and migration of HepG2 cells and promote apoptosis in a dose-dependent manner, which may be due to the promotion of the aerobic metabolism of cells.

Adequate inflammation can effectively eliminate harmful substances and prevent disease as a self-protective measure to prevent further damage to the body,while abnormally activated inflammation is detrimental to the body.Nucleotide binding and oligomerization domain-like receptor protein 3(NLRP3)inflammasome that participates in inflammatory responses are closely related to many physiological and pathological processes and play an important role in the occurrence and development of pulmonary diseases.This article mainly reviewed the activation mechanism and hypothesis of NLRP3 inflammasome,as well as the research on treating respiratory diseases by interfering with NLRP3 inflammasome.

To develop a caregiver parenting behavior scale for children aged 2 to 6 years, and to verify its reliability and validity. This study recruited 1 350 caregivers of children aged 2 to 6 years. The item discrimination analysis and exploratory factor analysis were used to analyze the structure, dimensions and items of the scale. Homogeneity reliability, split-half reliability and test-retest reliability were used to analyze the reliability of the scale. Content validity and construct validity were used to analyze the validity of the scale. The results showed that the final scale contained 7 dimensions and 45 items. Cronbach's α coefficient of the total scale was 0.945; the coefficient of split half was 0.899; the test-retest reliability analysis showed that the correlation coefficients between the two tests were 0.893 (total score), 0.854 (social), 0.832 (language), 0.871 (gross motor), 0.893 (fine motor), 0.862 (cognitive), 0.832 (self-care), and 0.872 (sensory). The content validity analysis was carried out by two rounds of expert argumentation using Delphi expert consultation method. The Kendall coefficient of the items score in two rounds of Delphi expert consultation was 0.813 (P<0.01). The structure validity analysis showed that there were significant correlations between each dimension and the total scale, also between each dimension of the scale, and the extracted average variance values of each dimension was greater than the correlation coefficients between this dimension and other dimensions. In conclusion, the reliability and validity of the scale are qualified. It can be used as a tool to evaluate and guide the parenting behavior of caregivers of children aged 2 to 6 years.

OBJECTIVE: To observe the effects of moxibustion at "Baihui" (GV 20) and "Dazhui" (GV 14) at different time points on the serum level of β-endorphin (β-EP), substance P (SP) and expression of interleukin-1β (IL-1β) and cyclooxygenase-2 (COX-2) protein in brainstem in rats with migraine, and to explore the effect and mechanism of moxibustion in preventing and treating migraine. METHODS: Forty male SD rats were randomly divided into a blank group, a model group, a prevention+treatment (PT) group and a treatment group, 10 rats in each group. Except the blank group, the rats in the remaining groups were injected with nitroglycerin subcutaneously to prepare migraine model. The rats in the PT group were treated with moxibustion 7 days before modeling (once a day) and 30 min after modeling, while the rats in the treatment group were treated with moxibustion 30 min after modeling. The "Baihui" (GV 20) and "Dazhui" (GV 14) were taken for 30 minutes each time. The behavioral scores in each group were observed before and after modeling. After intervention, ELISA method was used to detect the serum level of β-EP and SP; the immunohistochemistry method was used to detect the number of positive cells of IL-1β in brainstem; the Western blot method was used to detect the expression of COX-2 protein in brainstem. RESULTS: Compared with the blank group, the behavioral scores in the model group were increased 0-30 min, 60-90 min and 90-120 min after modeling (P<0.01); compared with the model group, in the treatment group and the PT group, the behavioral scores were decreased 60-90 min and 90-120 min after modeling (P<0.01). Compared with the blank group, in the model group, the serum level of β-EP was decreased (P<0.01), while the serum level of SP, the number of positive cells of IL-1β in brainstem and the expression of COX-2 protein were increased (P<0.01). Compared with the model group, in the PT group and and the treatment group, the serum level of β-EP was increased (P<0.01), while the serum level of SP, the number of positive cells of IL-1β and the expression of COX-2 protein in brainstem were decreased (P<0.01, P<0.05). Compared with the treatment group, in the PT group, the serum level of β-EP was increased and COX-2 protein expression was decreased (P<0.05). CONCLUSION Moxibustion could effectively relieve migraine. The mechanism may be related to reduce the serum level of SP, IL-1β and COX-2 protein expression in brainstem, and increase the serum level of β-EP, and the optimal effect is observed in the PT group.

Objective:To study the characteristics and clinical significance of mitochondrial injury of T lymphocyte subsets in patients with autoimmune hepatitis (AIH).Methods:The clinical data of 57 patients with AIH (AIH group) from June to December 2021 in Hangzhou Xixi Hospital were retrospectively analyzed, while 60 healthy physical examiners were included as healthy group. The peripheral blood T lymphocyte subsets (CD 8+ T lymphocyte count and CD 4+ T lymphocyte count) were detected by flow cytometry, and matched mitochondrial staining value according to certain algorithm was used to determine the mitochondrial damage of helper T lymphocyte (Th cell) and suppressor T lymphocyte (Ts cell). The levels of IgG, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured using a Roche E170 automatic electrochemiluminescence immunoassay. Anti-nuclear antibody (ANA) titer was measured by immunofluorescence. Multivariate Logistic regression was used to analyze the independent risk factors of mitochondrial damage of Th cell and Ts cell in patients with AIH. Results:The ALT, AST, IgG, positive rate of ANA titer, CD 4+ T lymphocyte count, CD 8+ T lymphocyte count, rate of Th cell mitochondrial injury and rate of Ts cell mitochondrial injury in AIH group were significantly higher than those in healthy group: (118.90 ± 37.61) U/L vs. (30.96 ± 14.37) U/L, (102.40 ± 36.51) U/L vs. (31.12 ± 14.06) U/L, (18.40 ± 3.71) g/L vs. (13.89 ± 1.98) g/L, 96.49% (55/57) vs. 16.67% (10/60), 438 (323, 637) × 10 6/L vs. 398 (272, 469) × 10 6/L, 296 (211, 296) × 10 6/L vs. 270 (193, 322) × 10 6/L, 61.40% (35/57) vs. 8.33% (5/60) and 82.46% (47/57) vs. 11.67% (7/60), and there were statistical differences ( P<0.01 or <0.05). Multivariate Logistic regression analysis result showed that the AST elevated and CD 8+ T lymphocyte count reduced were the independent risk factors of Ts cell mitochondrial injury in patients with AIH ( OR = 1.06 and 0.99, 95% CI 1.01 to 1.10 and 0.99 to 1.00, P<0.05); the ALT elevated and IgG elevated were the independent risk factors of Th cell mitochondrial injury in patients with AIH ( OR = 1.08 and 1.66, 95% CI 1.02 to 1.14 and 1.11 to 2.48, P<0.05). Conclusions:It is of positive clinical significance to measure the T lymphocyte subtype mitochondrial injury in patients with AIH. The probability of mitochondrial injury of T lymphocyte subtype can be predicted by biochemical indexes such as ALT, AST and IgG, so as to indirectly evaluate the liver cell necrosis.
