Objective:To explore the expression of nuclear factor-κB (NF-κB) and β-catenin in skin lesions of condyloma acuminatum, and analyze their relationship with clinical prognosis.Methods:A prospective study was conducted to select 96 patients with condyloma acuminatum admitted to the First Affiliated Hospital of Heilongjiang University of Traditional Chinese Medicine from December 2020 to June 2023 as the case group. Another 96 normal tissue samples from patients who underwent external genital plastic surgery or circumcision at the same time in the hospital were taken as the control group. All patients in the case group received 5-aminolevulinic acid photodynamic therapy (ALA-PDT) treatment, and the outcome was achieved at 6 months after follow-up. The case group was divided into recurrent subgroups and non- recurrent subgroups based on whether there was a recurrence. The expression of NF-κB and β-catenin in patients with different prognoses between the case group and the control group were compared. The Phi coefficient was used to analyze the correlation between NF-κB, β-catenin, and condyloma acuminatum. COX regression analysis were used to test the relationship between NF-κB, β-catenin and recurrence, and then receiver operating characteristic (ROC) curve was drawn to analyze the predictive value of NF-κB, β-catenin for recurrence in patients with condyloma acuminatum.Results:The positive rates of NF-κB and β-catenin in the lesion tissues of the case group were higher than those in the control group: 55.21%(53/96) vs. 23.96%(23/96), 56.25%(54/96) vs. 36.46%(35/96), and there were statistical differences ( P<0.05). According to the Phi coefficient test, there was a positive correlation between NF-κB and β-catenin positivity and condyloma acuminatum ( r>0, P<0.05). After 6 months of follow-up, 35 of the 96 patients relapsed, with a recurrence rate of 36.46% (35/96). The positive rates of NF-κB and β-catenin in the recurrent subgroup were significantly higher than those in the non-recurrent subgroup: 85.71%(30/35) vs. 37.70%(23/61), 85.71%(30/35) vs. 39.34%(24/61), and there were statistical differences ( P<0.05). COX regression analysis showed that the positive expression of NF-κB and β-catenin was related to the recurrence of patients with condyloma acuminatum after treatment ( HR = 4.017, 3.898, 95% CI 1.516 - 10.646, 1.470 - 10.336, P<0.05). The ROC curve showed that NF-κB, β-catenin, and their combination had moderate predictive value for recurrence in patients with condyloma acuminatum after treatment. The area under the curve (AUC) was 0.740 and 0.732, respectively. Among them, the combined predictive value was the highest, with an AUC of 0.810 ( P<0.05). Conclusions:The positive rates of NF-κB and β-catenin in the skin lesions of patients with condyloma acuminatum are relatively high, and they have certain predictive value for the recurrence of patients after treatment.

ObjectiveTo explore the effect of different drying conditions on the appearance and intrinsic quality indicators of Pinelliae Rhizoma for screening suitable drying conditions， so as to provide reference for its standardized production and quality evaluation. MethodsDifferent dried samples of Pinelliae Rhizoma were prepared by lime-assisted sweating method and intermittent drying method. Visual analysis was employed to measure the color brightness values（L^*） of the surface， cross-section and powder of the samples， texture analyzer was used to determine the hardness of the samples under different drying conditions. The total starch content was calculated by measuring the contents of amylose and amylopectin in the samples with ultraviolet-visible spectroscopy. High performance liquid chromatography（HPLC） was used to determine the contents of seven nucleoside components（uracil， hypoxanthine， uridine， inosine， guanosine， β-thymidine and adenosine） in the samples. Pearson correlation analysis was conducted to explore the correlation between the external characteristics and intrinsic indicators of the different dried samples. Principal component analysis（PCA） was used to comprehensively rank the data of various indicators， and partial least squares-discriminant analysis（PLS-DA） was used to screen differential components with variable importance in the projection（VIP） value>1. Furthermore， the difference between the optimal drying condition for Pinelliae Rhizoma and the traditional sun-drying method was explored by independent samples t-test. ResultsWith the increase of temperature， the color of the intermittently dried samples gradually deepened， while their hardness gradually decreased. Concurrently， the contents of extract， total starch， uridine and adenosine exhibited an upward trend， whereas the contents of uracil， hypoxanthine and inosine displayed a downward trajectory. Compared with the intermittent drying group， the content of extract in the samples subjected to lime-assisted sweating increased. With the increase of lime dose， the hardness and the total content of nucleoside components in the samples showed a downward trend， while the total starch content showed an upward trend. Correlation analysis showed that the comprehensive score of L^* was negatively correlated with the contents of uracil， hypoxanthine and inosine， and positively correlated with the contents of uridine， guanosine and adenosine. Hardness was negatively correlated with adenosine content， and positively correlated with the contents of inosine， uracil and hypoxanthine. Through comprehensive consideration and comprehensive score of principal components， the method of 5% lime-mixed sweating for 6 days emerged as the top-ranking approach. Except for the extract， the results of independent samples t-test showed that there was no significant difference between the 5% lime-mixed sweating for 6 days and the traditional sun-drying in terms of other content indicators. ConclusionThe whiteness and firmness of Pinelliae Rhizoma exhibit significant correlations with its chemical composition， while uridine， uracil， guanosine， adenosine and inosine are the key constituents responsible for the quality difference of Pinelliae Rhizoma under different drying conditions. The lime-assisted sweating method optimized in this study can be proposed as a viable alternative to the traditional sun-drying method. This method not only ensures the quality of the medicinal material but also effectively reduces the drying time and prevents mold contamination， which provides a valuable reference for the standardization of drying conditions and the establishment of quality evaluation criteria for Pinelliae Rhizoma.

Lipopolysaccharide (LPS) was used to induce mouse mononuclear macrophages (RAW 264.7 cells) to establish the inflammation model for investigating the effect and mechanism of Mailuoning oral liquid on arteriosclerosis occlusion (ASO) in vitro. RAW264.7 cells viability was measured by MTT assay. NO concentration was determined by Griess. mRNA levels and protein expressions of NFAT5/NLRP3 signaling pathway were detected by Q-PCR and Western blot. The relationship between NFAT5 and NLRP3 was explored by cellular transfection of NFAT5-siRNA combined with Western blot. Nuclear translocation of NFAT5 was detected by immunofluorescence. The results showed that Mailuoning oral liquid decreased the NO release induced by LPS in RAW264.7 cells. The mRNA levels of NFAT5, NLRP3, caspase1, IL-18 and MMP9, the protein expressions of NFAT5, NLRP3, cleaved-caspase1 (p20) and the phosphorylation of NF-κB-P65 were decreased after administration of Mailuoning oral liquid. NFAT5-siRNA significantly reversed the increase in protein expressions of NLRP3 induced by LPS in RAW264.7 cells. Both Mailuoning oral liquid and KRN2 (NFAT5 inhibitor) could inhibit the expressions and nuclear translocation of NFAT5. In conclusion, Mailuoning oral liquid exert significant anti-inflammatory effects in vitro by inhibiting the NFAT5/NLRP3 signaling pathway, and NFAT5 might be involved in regulating the expressions of NLRP3.

Vascular cognitive impairment (VCI), caused by cerebrovascular dysfunction, severely impacts the quality of life in the elderly population, yet effective therapeutic approaches remain limited. Mitophagy, a selective mitochondrial quality-control mechanism, has emerged as a critical focus in neurological disease research. Accumulating evidence indicates that mitophagy modulates oxidative stress, neuroinflammation, and neuronal apoptosis. Key signaling pathways associated with mitophagy—including PINK1/Parkin, BNIP3/Nix, FUNDC1, PI3K/Akt/mTOR, and AMPK—have been identified as potential therapeutic targets for VCI. This review summarizes the mechanistic roles of mitophagy in VCI pathogenesis and explores emerging therapeutic strategies targeting these pathways, aiming to provide novel insights for clinical intervention and advance the development of effective treatments for VCI.

Objective:To study the genetic polymorphisms of short-tandem repeats (STR) for the D13S317 locus among an ethnic Han Chinese population and verify a novel tri-allelic pattern identified for the locus. Methods:A total of 378 paternity test cases from Guangdong Forensic Authentication Institute from October 17, 2017 to December 28, 2017 were selected as the study subjects. A GlobalFiler? Express kit was used for the STR genotyping. Samples suspected for having a novel tri-allelic pattern were verified with a PowerPlex ? 21 kit. Potential variant of the primer-binding region and flanking sequences underlying the tri-allelic pattern was excluded by molecular cloning and sequencing. Results:Six alleles were detected for the D13S317 locus, with the characteristic distribution frequencies being 8 (29.1%), 9 (13.1%), 10 (15.21%), 11 (24.21%), 12 (13.89%) and 13 (3.44%), respectively. In one of the families, the D13S317 locus of the proband was suspected to harbor a triband allele (8, 9, 10). A re-test has confirmed the result of initial test. Molecular cloning and sequencing analysis of the D13S317 locus in the proband and his daughter has failed to find allelic variants in the primer-binding region and flanking sequence, which has confirmed the novel tri-allelic pattern for the locus. Conclusion:A novel type 2 tri-allelic pattern (8, 9, 10) at the D13S317 locus has been identified among the ethnic Han Chinese population. The pattern has not been transmitted to the female offspring, and has been included in the international STRBase database for the first time.
