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.

Objective To explore the correlation of traditional Chinese medicine(TCM)syndrome elements with language function and activities of daily living(ADL)in patients suffering post-stroke aphasia(PSA).Methods Ninety-eight PSA patients hospitalized at the College of Rehabilitation Medicine,Fujian University of Traditional Chinese Medicine from April 2023 to April 2024 were selected.The language function,TCM syndrome elements,and their correlations were analyzed.Results(1)Among PSA patients,males outnumbered females.PSA patients exhibited different performances on various aphasia-related scales,with language impairments mainly concentrated in naming and spontaneous speech.(2)The distribution of TCM syndrome elements varied in PSA patients with different age groups.In the age group＜50 years old,qi obstruction(100.00%),phlegm syndrome(100.00%),and dampness syndrome(100.00%)were predominant.In the age group of 50-59 years old,phlegm syndrome(100.00%)and yang hyperactivity syndrome(96.30%)were predominant.In the age group of 60-69 years old,phlegm syndrome(100.00%)and yang hyperactivity syndrome(96.15%)were also predominant.In the age group of 70-79 years old,qi deficiency syndrome(100.00%)was predominant.In the age group of 80-89 years old,syndromes such as qi insecurity,qi obstruction,qi deficiency,phlegm,yang hyperactivity,blood stasis,wind stirring,and blood cold were concentrated(all 100.00%).However,there were no statistically significant differences in the distribution of TCM syndrome elements among various age groups(P＞0.05).(3)The distribution of deficiency and excess syndrome elements varied in PSA patients with different genders.Among deficiency syndrome elements,yang hyperactivity,qi deficiency,and yin deficiency were predominant in males,while yang hyperactivity,qi deficiency,and blood deficiency were predominant in females.Among excess syndrome elements,phlegm syndrome,qi obstruction,and dampness syndrome were predominant in males,while phlegm syndrome,qi obstruction,and qi stagnation syndrome were predominant in females.However,there were no statistically significant differences in the distribution of deficiency and excess syndrome elements between genders(P＞0.05).(4)After controlling the factors of age group and gender,partial correlation analysis of syndrome elements and language function showed that among the disease-location syndrome elements,spontaneous naming(r=-0.588,P=0.027)and sematic cued naming(r=-0.558,P=0.038)in the Boston Naming Test(BNT)were negatively correlated with the large intestine;among the disease-nature syndrome elements,BNT sematic cued naming(r=0.821,P＜0.001)was positively correlated with qi sinking,while BNT spontaneous naming was negatively correlated with blood heat(r=-0.544,P=0.044)and was positively correlated with fluid depletion(r=0.860,P=0.028);BNT recognitive naming was positively correlated with external wind(r=0.966,P=0.034);errors in BNT sematic cued naming were negatively correlated with qi sinking(r=-0.540,P=0.005);the Modified Barthel Index(MBI)was positively correlated with essence deficiency(r=0.572,P=0.021).Conclusion The TCM syndrome elements of phlegm,qi block,yang hyperactivity,and qi deficiency are commonly seen in PSA patients.There is a certain correlation of language function and ADL with TCM syndrome elements in PSA patients.

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.

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.

Objective To prepare the liposomes of total flavonoids from Lonicerae Japonicae flos(LJFTF)and evaluate their inhibitory effect on methicillin-resistant Staphylococcus aureus(MRSA).Methods LJFTF liposomes were prepared by ethanol injection.Then the preparation process was optimized by star point design-effect surface method,with the concentrations of phospholipid,mass ratio of phospholipid to cholesterol and mass concentration of LJFTF as the influencing factors,and the encapsulation rate and drug-loading rate as evaluation indicators.The obtained liposomes were characterized by observing their properties,measuring particle size,polymer dispersity index(PDI)and Zeta potential through laser particle size analyzer.High performance liquid chromatography(HPLC)was used to determine the release rate of the liposomes.The antibacterial activity of the liposomes against MRSA was observed by plate method and live/dead staining,and the inhibitory effect of the liposomes on MRSA biofilm was observed by crystal violet staining.Results After optimization and verification,the best preparation process was as follows:phospholipid concentration 35.0 mg/mL,phospholipid to cholesterol mass ratio 15.0,and LJFTF concentration 5.7 mg/mL.The prepared liposomes were light yellow emulsion,with an average encapsulation rate of 86.37％(RSD=0.37％,n=3),and an average drug-loading rate of 11.69％(RSD=0.09％,n=3),a particle size of 173.60±1.07 nm,a PDI value of 0.15±0.05,and a Zeta potential of-4.86±0.60 mV.The free LJFTF was completely released within 4 h from the dialysis bag,and the in vitro cumulative release of LJFTF was(59.44±3.58)％at 12 h and(63.58±5.78)％at 30 h.Plate and live/dead staining showed that the prepared liposomes significantly inhibited the growth and promoted the death of MRSA strain.Crystal violet staining displayed that the liposomes significantly inhibited the formation of MRSA biofilm(P＜0.001),with significant difference in comparison with same dose of LJFTF(P＜0.001).Conclusion LJFTF liposomes are successfully prepared,and the formulation process has been optimized.The liposomes show significant anti-MRSA activity in vitro.

Objective To explore the value of constructing a model to predict the number of positive cores in systematic biopsy in prostate cancer(PCa)using a combination of radiomics features based on magnetic resonance imaging and clinical indicators.Methods Retrospectively collected magnetic resonance imaging and clinical data from two medical institutions(Gansu Provincial Hospital from January 2018 to February 2023,Zhangye People's Hospital Affiliated to Hexi College from April 2020 to February 2023).The 155 patients from Gansu Provincial Hospital were randomly divided into a training set(n=109;80 cases with positive needle count≥6 and 29 cases with positive needle count<6)and an internal validation set(n=46;34 cases with positive needle count≥6 and 12 cases with positive needle count<6)in a 7:3 ratio.The 43 patients from Zhangye People's Hospital Affiliated to Hexi College were used as external validation set.Small field of view high-resolution T2-weighted imaging(sFOV HR-T2WI)and contrast-enhanced delayed-phase images were selected to extract radiomic features from the three-dimensional region of interest of the entire prostate,and radiomics model was constructed and Radscores calculated after dimensionality reduction and feature selection.Univariate and multivariate logistic regressions were used to screen for independent risk factors for positive cores in systematic biopsy.Nomogram was constructed using Radscore and clinical independent risk factors to predict the number of positive cores in systematic biopsy in PCa patients,which was then externally validated.Results Age,alkaline phosphatase(ALP),free prostate specific antigen(FPSA),total prostate specific antigen(TPSA),FPSA/TPSA ratio,and prostate specific antigen density(PSAD)were not statistically significantly different between the training,internal validation,and external validation sets(P>0.05).FPSA,TPSA,FPSA/TPSA ratio,and PSAD were significantly different between the positive cores<6 and positive cores≥6 groups(P<0.001).Univariate logistic regression analysis showed that FPSA(P<0.001),TPSA(P<0.001),FPSA/TPSA ratio(P=0.001),PSAD(P<0.001),and Radscore(P<0.001)were risk factors for positive cores in systematic biopsy in PCa.Multivariate logistic regression analysis showed that PSAD(OR=0.251,95%CI 0.063-0.996,P=0.049)and Radscore(OR=1.990,95%CI 1.409-2.812,P<0.001)were independent risk factors for positive cores in systematic biopsy in PCa.The clinical models achieved AUCs of 0.849(95%CI 0.774-0.924),0.817(95%CI 0.693-0.941),and 0.631(95%CI 0.439-0.822);the 12 features for radiomics models are derived solely from sFOV HR-T2WI,the radiomics models achieved AUCs of 0.868(95%CI 0.791-0.945),0.846(95%CI 0.695-0.996),and 0.815(95%CI 0.660-0.970);the nomogram achieved AUCs of 0.921(95%CI 0.869-0.973),0.868(95%CI 0.743-0.992),and 0.840(95%CI 0.702-0.978)in the training set,internal validation set,and external validation set,respectively.Conclusions The combination of radiomic features extracted from sFOV HR-T2WI and PSAD can preoperatively be used as a noninvasive manner to predict the number of positive cores of the PCa patients.This approach has a certain value in risk stratification of PCa patients and guiding personalized clinical management.

Abstract: Objective To analyze the epidemic characteristics and influencing factors of school influenza-like cases in 2011-2022 in Nanchang, so as to provide reference for the prevention and control of school influenza outbreaks. 　　　Methods The epidemiological relevant data of school influenza-like cases from 2011 to 2022 in Nanchang and the pathogen test results of respiratory tract samples were collected for epidemiological and etiology analysis. Results　From 2011 to 2022, a total of 142 influenza-like cases were reported in schools in Nanchang, with a cumulative morbidity of 2 880 cases and a morbidity rate of 1.89%. A total of 1 263 samples were collected, with an overall positive influenza nucleic acid detection rate of 58.91%. The highest proportion of outbreaks occurred in 2017-2019, while the lowest incidence was in 2011-2013. Outbreaks mainly occurred from November to March of the following year (accounting for 79.58%), presenting obvious seasonal characteristics. The distribution was mainly in primary schools, accounting for 70.42% (100/142) of all outbreaks. From 2011 to 2022, all types of influenza viruses were tested, and more than 2 types of influenza viruses were prevalent each year. The dominant strains alternated between influenza A H1N1, influenza A H3N2 and Victoria lineages of type B influenza viruses. From 2011 to 2019, the influenza epidemic in schools in Nanchang showed a continuous upward trend. During COVID-19 in 2020-2022, Nanchang adopted a variety of non-drug prevention and control measures for COVID-19, and both the number of influenza epidemics in various schools and the number of influenza virus nucleic acid positive cases decreased. The average number of classes involved in the epidemic was (3±2), and the average duration of the epidemic was (8±4) days. 　Conclusions The outbreaks of influenza-like illness in Nanchang schools is highly prevalent in winter and spring, , with urban primary schools being the high incidence locations. Non-drug prevention and control measures for COVID-19 have an impact on the epidemic trend of influenza, so the continuous monitoring of the school influenza virus activities and improving the timeliness of the report will be conducive to the rapid control of the epidemic.
