Background: and Purpose Ruptured intracranial aneurysms (RIA) are associated with a mortality rate of up to 40% in the Chinese population, highlighting the critical need for targeted treatment interventions for at-risk individuals. Although the impact of aldehyde dehydrogenase 2 (ALDH2) gene mutations on susceptibility to intracranial aneurysms (IA) is well documented, the potential connection between ALDH2 rs671 single-nucleotide polymorphism (SNP) and RIA remains unexplored. Given the increased prevalence of ALDH2 gene mutations among Chinese Han individuals, it is clinically relevant to investigate the link between ALDH2 rs671 SNP and IA rupture. Methods: A prospective study was conducted on 546 patients diagnosed with IA to investigate the association between ALDH2 rs671 SNP and the risk of IA rupture. Results: The ALDH2 rs671 SNP (ALDH2*2) was significantly more prevalent in patients with unruptured IA (UIA) than in those with RIA (32.56% vs. 18.58%, P=0.004). Multivariate logistic regression analysis revealed that people with the ALDH2 mutation (ALDH2*1/*2 and ALDH2*2/*2 gene type) had a significantly reduced odds ratio (OR=0.49; 95% confidence level [CI] 0.27–0.88; P=0.018) for RIAs. Age-specific subgroup analysis indicated that the ALDH2 mutation provided a stronger protective effect in individuals aged 60 years and above with IA compared to those under 60 years old (OR=0.38 vs. OR=0.52, both P<0.05). Conclusion The incidence of RIA was significantly higher in individuals with a normal ALDH2 gene (ALDH2*1/*1) than in those with an ALDH2 rs671 SNP (ALDH2*1/*2 or ALDH2*2/*2). ALDH2 rs671 SNP may serve as a protective factor against RIA in the Chinese Han population.

AIM To establish a rapid quantitative analysis model for saponins in Paris polyphylla var.yunnanensis(PPY)by near infrared spectroscopy.METHODS The contents of polyphyllins Ⅰ,Ⅱ,Ⅶ and there total content in PPY were determined by HPLC,while spectral data within the range of 10 000 to 4 000 cm-1 were collected.A quantitative analysis model was established by combining these data with partial least squares regression(PLSR).Multivariate scatter correction(MSC)and vector normalization(SNV)were applied prior to further preprocessing the spectra with original,first-order derivative(1stD),or second-order derivative(2ndD)treatments.Lastly,the model was optimized through non-smoothing(NS),Norris Derivative filtering(Nd),and Savitzky-Golay filtering(S-G)method.Model stability was evaluated based on correlation coefficients and variance.The predicted contents of each saponin component in the validation set samples were calculated.RESULTS The contents of polyphyllins Ⅰ,Ⅱ,Ⅶ were 0.42-17.98,0.46-10.44,0.23-3.86 mg/g,respectively.The total content ranged from 2.91 to 22.1 mg/g.The optimal parameters of three saponins were achieved when selecting the MSC+2ndD+S-G pretreatment method.The corresponding ratio of line segment length to segment gap was 13∶5,15∶5,11∶5,with correlation coefficients of 0.982,0.930,0.958,respectively.The root mean square errors of calibration(RMSEC)were 0.702,0.797,0.238,and the root mean square errors of prediction(RMSEP)were 1.120,0.835,0.304,respectively.The optimal parameters for the total content were obtained when selecting the MSC+2ndD+NS pretreatment method,with a correlation coefficient of 0.970,a RMSEC of 1.090,and a RMSEP of 1.740.CONCLUSION This accurate and rapid method can be used for detection of saponin contents in P.Polyphylla.

Objective:To retrospectively analyze the current status of consultation, clinical characteristics, and treatment status of patients with IgG4-related disease (IgG4-RD) in order to provide assistance and a basis for early and standardized diagnosis and treatment.Methods:IgG4-RD cases admitted to our hospital from June 2015 to October 2023 were collected. The details of patients' basic information, initial symptoms, department visits, laboratory and imaging findings, histopathological examination results, and treatment plans were recorded. A statistical descriptive analysis was performed on the data.Results:A total of 105 patients with IgG4-RD were included, with a median age of 59.0 (18.0, 78.0) years. The main departments visited were clinical immunology and gastroenterology (83.8%, 88/105). The median diagnostic duration was eight months, with a maximum of 300 months, and 33.3% (35/105) of patients needed over one year for diagnosis. 92 cases underwent histopathological examinations and IgG4 staining, with a total positivity rate of 87.0% (80/92). Among these, sixteen cases underwent pathological examination after surgery, with a positivity rate of 100%; the remaining 76 cases out of 92 underwent liver biopsy, with a positivity rate of 76.1%. Out of these, there were 22 cases from the pancreas, 21 from the submaxillary gland, nine from the labial gland, and seven each from the duodenal papilla and liver, with positivity rates of 81.8%, 81.0%, 55.6%, 85.7%, and 85.7%, respectively. Eleven cases (10.5%) with normal serum IgG4 were diagnosed based on multi-organ involvement and pathological results. 94 cases (89.5%) had elevated IgG4, with a predominance of＞2.70 g/L. The median follow-up period for the 87 cases was 14 months. Two cases had poor response, twelve patients relapsed, five cases relapsed without combined drug treatment after surgery, five cases relapsed due to drug withdrawal, and two cases relapsed while tapering off steroids.Conclusions:As a multisystem disease, IgG4-RD still faces the difficulties of time-consuming diagnosis and inappropriate treatment. Therefore, it is necessary to rely on a multidisciplinary collaboration model to improve the awareness level and promote the early and standardized diagnosis and treatment of patients with IgG4-RD.

Objective:To investigate the expression and clinical significance of long noncoding RNA (lncRNA) AP006284.1 in bladder cancer tissues, and to analyze the regulatory effect and downstream mechanism of AP006284.1 knockdown on the proliferation and migration of bladder cancer cells. Methods:The expression of AP006284.1 in bladder cancer tissues, and the relationship between AP006284.1 expression and tumor stage and disease-free survival of bladder cancer patients were analyzed in the gene expression omnibus (GEO) database. AP006284.1 gene expression in bladder cancer cell lines, including MGH-U3, T24, UMUC-3, J82 and 5637, and bladder epithelial immortalized SV-HUC-1 cell were detected by real-time reverse transcription-PCR (RT-qPCR) assay. J82 cells were divided into the control group and the transfection group, and transfected with control plasmid and AP006284.1 knockdown plasmid, respectively. The effect of AP006284.1 knockdown on the proliferation of J82 cells was detected by RT-qPCR and cell counting kit-8 (CCK-8) assay. The effect of AP006284.1 knockdown on the migration of J82 cells was determined by the scratch healing assay. The target gene of AP006284.1 was predicted by LncRNA2Target and LncRNome databases. The target fragment of wild-type AP006284.1 ( AP006284.1-Wt) or mutant AP006284.1 ( AP006284.1-Mut) was constructed into pGL3 plasmid by dual luciferase gene reporter assay. J82 cells were co-transfected with miR-205-3p or miR-negtive control (miR-NC) to validate the targeting relationship between AP006284.1 and miR-205-3p. The correlation between miR-205-3p and AP006284.1 expression in bladder cancer tissues was further analyzed by the GEO database. The effect of AP006284.1 knockdown on the expression of miR-205-3p gene in J82 cells was detected by RT-qPCR assay. The effect of AP006284.1 knockdown on the expression of phosphorylated Ras protein (p-Ras), phosphorylated Raf protein (p-Raf), phosphorylated mitogen-activated protein kinase kinase (p-MEK), and phosphorylated extracellular signal-regulated kinase (p-ERK) of the ERK pathway was detected by Western blotting in J82 cells. Results:GEO database analysis showed that the relative expression of AP006284.1 in bladder cancer tissues ( n=304) was significantly higher than that in normal tissues ( n=28, P<0.01). The relative expression of AP006284.1 was positively correlated with the tumor stage of the bladder cancer patients ( P<0.01). Compared with bladder cancer patients with low expression of AP006284.1, patients with high expression had a lower disease-free survival ( P<0.01). Compared with the SV-HUC-1 cell (1.02±0.34), the expression level of AP006284.1 gene was upregulated in MGH-U3 cell (5.77±0.37), T24 cell (3.02±0.40), UMUC-3 cell (3.62±0.59), J82 cell (7.19±0.24) and 5637 cell (5.59±0.30) (all P<0.01). The expression level of the AP006284.1 gene was the highest in J82 cells, therefore, the J82 cells were selected for the study. The expression level of AP006284.1 gene in the control group (7.20±0.26) was 6.92 times higher than that in the transfection group (1.04±0.28, t=16.16, P<0.01). Compared with the control group (0.74±0.11, 1.35±0.09, 1.63±0.14, 1.74±0.11), the absorbance ( A) values of J82 cells in the transfection group (0.49±0.06, 0.95±0.14, 1.09±0.08, 1.13±0.11) were reduced than those in the control group at the 24, 36, 48 and 60 h after AP006284.1 knockdown (all P<0.05). The migration distance of J82 cells in the control group was significantly longer than that in the transfection group. The migration rate of the control group [(65.03±6.20)%], which was 2.58 times higher than that of the transfection group [(25.22±3.45)%, t=5.61, P<0.01]. The target site of miR-205-3p containing AP006284.1 was predicted by LncRNA2Target and LncRNome databases. Compared with miR-NC group (1.00±0.11), the relative activity of dual luciferase of AP006284.1-Wt gene was significantly downregulated in the miR-205-3p group (0.31±0.07, t=5.47, P<0.01). Compared with the miR-NC group (0.97±0.14), the relative activity of dual luciferase of AP006284.1-Mut vector (0.98±0.07) was not significantly change ( t=0.09, P>0.05). The GEO database analysis showed that the expression of AP006284.1 in bladder cancer tissues was negatively correlated with the expression of miR-205-3p ( P<0.01). The expression level of miR-205-3p gene in the transfection group (5.42±0.24) was 5.21 times higher than that in the control group (1.04±0.40, t=9.40, P<0.01). Compared with the control group (3.22±0.17, 5.56±0.19, 4.38±0.17, 5.74±0.36), the expressions of p-Ras (2.33±0.12), p-Raf (1.61±0.20), p-MEK (1.57±0.25), and p-ERK (2.40±0.28) of the ERK pathway were decreased in the transfected J82 cells (all P<0.01). Conclusions:AP006284.1 is highly expressed in bladder cancer tissues. Knockdown of AP006284.1 can inhibit the proliferation and migration of bladder cancer cells by regulating the miR-205-3p and ERK pathway proteins.

Hepatocellular carcinoma(HCC)is one of common cancer that seriously endangers human health.Designing methods for early,rapid,and accurate diagnosis of HCC has become the key point.Golgi protein 73(GP73),a novel potential biomarker for HCC,is crucial for diagnosis and treatment of HCC.In this study,a colorimetric sensor with rapidity,smplicity and high specificity was established for detection of GP73 based on peroxidase-like activity of hemin-reduced graphene oxide-manganese dioxide(H-rGO-MnO2).The H-rGO-MnO2-GP73Apt1 signal probe was synthesized by carboxyl of H-rGO-MnO2 nanozyme and amination of GP73 aptamer(GP73Apt1)though amide reaction.In the presence of GP73,the sulfhydryl-modifed GP73 aptamer(GP73Apt2),as the capture probe,and the signal probe both specifically recognized GP73,forming a sandwich structure(GP73Apt2-GP73-H-rGO-MnO2-GP73Apt1).This structure could catalyze the oxidation of H2O2 to produce hydroxyl radical(·OH),thereby oxidizing the colorless phthalenediamine(OPD)into the yellow 2,3-diaminophenazine(DPA).The quantitative detection of GP73 was achieved by measuring the characteristic absorbance of DPA at 450 nm.In the GP73 concentration range of 10-150 ng/mL,there was a good linear relationship between the DPA absorbance at 450 nm(A450 nm)and the GP73 concentration under optimal conditions.The linear equation was A450 nm=0.00321CGP73+0.8988,with the correlation coefficient(R2)of 0.9960 and the detection limit(LOD)of 5.38 ng/mL.The colorimetric sensor was applied to detection of GP73 in human serum samples,with recoveries of 88.4%?98.8%.This sensor showed high specificity,sensitivity,and stability,and had potential for clinical detection of GP73,providing a new approach for the early diagnosis of HCC.

Cholangiocarcinoma (CCA) is a malignant tumor originating from cholangiocytes. However, it remains unclear about the pathogenesis of this carcinoma, which may be related to multiple factors. Currently, CCA is mainly treated by surgery, chemotherapy, and radiotherapy. Among them, surgery is the only potentially curative option for CCA. Nevertheless, the high malignancy and asymptomatic nature of CCA may lead to poor treatment outcomes. It has been demonstrated that Chinese medicine (CM) plays a significant role in various antitumor applications. Meanwhile, CM exhibits fewer side effects and high availability. Moreover, the in vitro application of CM monomers has been explored in many domestic and foreign studies. This article mainly reviews the signaling pathways and molecular mechanisms of CM monomers in the treatment of CCA in recent years. These findings are expected to provide new insights into the treatment of CCA.
