AIM: To evaluate the diagnostic value of serum Th1-type cytokine levels and extraocular muscle-related parameters in thyroid-associated ophthalmopathy(TAO).METHODS: A retrospective study was conducted on 45 patients diagnosed with TAO in our hospital from January 2023 to December 2024, and 20 normal volunteers during the same period as controls. Venous blood samples of the patients were collected to detect the concentrations of Th1-type cytokines [interferon-γ(IFN-γ), tumor necrosis factor-α(TNF-α), interleukin-2(IL-2), and interleukin-12(IL-12)] in the serum. Additionally, the end diastolic velocity(Ved), velocity maximum(Vmax), resistance index(RI)of the central retinal artery, as well as the thickness and left-right diameter of the medial rectus muscle were measured. Logistic regression model was used to analyze the risk factors of TAO, and receiver operating characteristic curve(ROC)was adopted to evaluate the diagnostic efficacy of each index for the occurrence of TAO.RESULTS: The general information of the two groups was comparable. Compared with the normal control group, the serum concentrations of IFN-γ and TNF-α in TAO patients were significantly increased, Ved and Vmax were lower than those in the control group, and RI and the thickness of the medial rectus muscle were higher than those in the control group(all P<0.05). Logistic regression analysis showed that serum IFN-γ concentration, Ved, Vmax, and the thickness of the medial rectus muscle were all risk factors for TAO. ROC curve analysis indicated that the AUCs of serum IFN-γ concentration, Ved, Vmax, and the thickness of the medial rectus muscle for the diagnostic efficacy of TAO were 0.756, 0.769, 0.732, and 0.642, respectively. The combined detection of IFN-γ, Ved, Vmax, and the thickness of the medial rectus muscle had an AUC of 0.840 and a Youden index of 0.59, which was superior to the detection of a single indicator.CONCLUSION: The levels of serum Th1-type cytokines and extraocular muscle-related ultrasound indicators have certain value in the diagnosis of TAO. The combination of IFN-γ, Ved, Vmax, and the thickness of the medial rectus muscle has better diagnosis efficiency in TAO, which can provide a certain reference for the early diagnosis of TAO.

Coronavirus-related diseases pose a significant challenge to the global health system. Given the diversity of coronaviruses and the unpredictable nature of disease outbreaks, the traditional "one bug, one drug" paradigm struggles to address the growing number of emerging crises. Therefore, there is an urgent need for therapeutic agents with broad-spectrum anti-coronavirus activity. Here, we provide evidence that ATV006, an anti-SARS-CoV-2 nucleoside analog targeting RNA-dependent RNA polymerase (RdRp), has broad antiviral activity against human and animal coronaviruses. Using mouse hepatitis virus (MHV) and human coronavirus NL63 (HCoV-NL63) as a model, we show that ATV006 has potent prophylactic and therapeutic activity against murine coronavirus infection in vivo. Remarkably, ATV006 successfully inhibits viral replication in mice even when administered 96 h after infection. Due to its oral bioavailability and potency against multiple coronaviruses, ATV006 has the potential to become a useful antiviral agent against SARS-CoV-2 and other circulating and emerging coronaviruses in humans and animals.

The data were collated using Excel. Categorical data were described as numbers and percentages.Results:A total of 328 usable questionnaires were returned. Only 7.62% (25 people) believed that existing CRC training was sufficient and could meet actual work needs; 4.88% (16 people) responded that there was no training; 46.34% (152 people) believed that the training was insufficient to support actual work needs; 87.50% (287 people) believed that continuous CRC training was needed; 46.95% (154 people) preferred experienced CRCs for teaching, who should have at least 3 years of CRC work experience; and 46.95% (154 people) preferred a duration of 3 months for CRC training. The preferred training methods were: practice under the direction of experienced CRCs (90.85%, 298 people), step-by-step teaching of practical skills (88.41%, 290 people), case analysis and discussion (87.20%, 286 people), process simulation (83.23%, 273 people), and lecture-based teaching (76.52%, 251 people). The preferred post-training assessment methods were: case analysis (76.52%, 251 people), operation simulation (74.09%, 243 people), process simulation (73.17%, 240 people), written examination (66.16%, 217 people), and interview (63.72%, 209 people).Conclusions:The current pediatric CRC training is not enough to meet actual work needs. It is urgent to develop and promote a CRC training system that can meet work needs, laying the foundation for the construction of pediatric clinical research ecology in China.

Objective:To explore the effect of complement component C1s on the proliferation,migration and adhesion of esophageal squamous cell carcinoma(ESCC)cells and on the growth of xenograft tumors in nude mice.Methods:The C1S mRNA ex-pression of ESCC tissues and adjacent normal tissues(ANTs)were analyzed using NCBI-GEO database.The C1s expression of ESCC cell lines was analyzed with RT-qPCR and Western blot.The knockdown or overexpression of C1s in ESCC cells lines was performed using C1s small interfering RNA(siRNA),C1s short hairpin RNA(shRNA)or C1s overexpression lentivirus,and the cell prolifera-tion was detected by CCK-8 assay,cell migration was detected by cell wound healing assay,cell adhesion was detected by cell-matrix adhesion assay,the expressions of matrix metalloproteinases MMP1 and MMP13 were detected by Western blot,and the effect of C1s on the growth of xenograft tumors in nude mice was detected by subcutaneous tumorigenesis assay in nude mice.The expression of CD34 in the xenograft tumors was detected by immunohistochemistry,and the formation of tumor microvessel was analyzed.Results:The expression of C1S mRNA in ESCC tissues was significantly higher than that in ANTs.Knockdown of C1s significantly suppressed proliferation,migration and cell-matrix adhesion of ESCC cells,as well as growth of xenograft tumors in nude mice,while overexpres-sion of C1s had the opposite effects.The expressions of MMP1 and MMP13 were decreased in ESCC cells TE-1 with C1s knockdown.Compared with control group,the microvessel of the xenograft tumors in the C1s overexpression group were more abundant.Conclu-sion:C1s is significantly upregulated in ESCC tissues,and promotes proliferation,migration,cell-matrix adhesion of ESCC cells,and the growth of xenograft tumors.C1s may play an important role in the occurrence and development of ESCC.

Objective To investigate the effect of miR-130a targeting phosphase and tensin homology deleted on chromosome ten(PTEN)/phosphoinositide 3 kinase(PI3K)/protein kinase B(AKT)pathway on renal tissuecell apoptosis in diabetic kidney disease(DKD)rats.Methods The DKD rat model was constructed by feeding high-sugar and high-fat diet combined with intraperitoneal injection of streptozotocin(STZ).72 rats were divided into normal control group(NC),DKD model group(DKD),miR-130a agonist negative control group(NC agomir),and miR-130a agonist group(miR-130a agomir),miR-130a agomir+ PTEN overexpression negative control group(miR-130a agomir+pcDNA),and miR-130a agomir+ PCDNA-PTEN overexpression group(miR-130a Agomir + PCDNA-PTEN),with12 rats in each group.Urinary microalbumin kit was used to detect 24 h urine albumin(UAlb).Fasting blood glucose(FBG),serum creatinine(Scr)and blood urea nitrogen(BUN)were detected by automatic biochemical analyzer.Pathological changes of renal tissue were detected by HE staining.The levels of serum IL-6 and TNF-α were detected by ELISA.The apoptosis of renal tissue was detected by TUNEL staining.The expression of miR-130a was detected by qRT-PCR,and the expression of B-cell lymphoma-2-associated X protein(Bax),B-cell lymphoma-2(Bcl-2)and PTEN/PI3K/AKT pathway were detected by Western blot.Dual luciferase reporter gene experiment was used to verify the targeting relationship between miR-130a and PTEN.Results Compared with DKD and NC agomir groups,24 h UAlb,FPG,Scr,BUN,IL-6,TNF-α,renal cell apoptosis rate,Bax protein expression and PTEN protein expression in miR-130a agomir group were decreased(P＜0.05).The expressions of miR-130a,Bcl-2,p-Akt/AKT protein were increased(P＜0.05).Compared with miR-130a agomir group,24 h UAlb,FPG,Scr,BUN,IL-6,TNF-α,renal cell apoptosis rate,Bax protein expression and PTEN protein expression were increased in miR-130a agomir+pcDNA-PTEN group(P＜0.05).The expression of Bcl-2,p-Akt/AKT protein decreased(P＜0.05).Conclusion Overexpression of miR-130a may inhibit renal cell apoptosis in DKD rats by down-regulating PTEN to activate PI3K/AKT pathway.

Objective:To investigate the clinical efficacy and safety of ZR2 (zevalin + lenalidomide + rituximab) regimen in the treatment of elderly patients with diffuse large B-cell lymphoma (DLBCL).Methods:A retrospective case series study was conducted. The clinical data of 16 elderly (>65 years old) non-germinal center B-cell-like DLBCL patients treated with ZR2 regimen at the Taixing People's Hospital from January 2021 to March 2023 were retrospectively analyzed. The efficacy, adverse reactions and prognosis of patients were observed.Results:Of the 16 patients, 11 were male and 5 were female, with the age [ M ( Q1, Q3)] of 76 years old (70 years old, 78 years old), and 10 cases were Ann Arbor stage Ⅲ-Ⅳ. Among the 16 patients, 9 achieved complete remission, 4 patients achieved partial remission. All 16 patients experienced varying degrees of reversible bone marrow suppression, grade Ⅲ-Ⅳ hematologic adverse reactions included neutropenia (7 cases) and thrombocytopenia (2 cases), and the bone marrow hematopoiesis recovered after treatment with granulocyte colony-stimulating factor and thrombopoietin. The main ≥grade Ⅱ non-hematologic adverse reactions were gastrointestinal reactions (5 cases), liver function abnormalities (3 cases) and peripheral neuropathy (2 cases), which were improved after the appropriate treatment. Two patients discontinued the treatment of this regimen due to disease progression, and 1 patient died from complications after 2 cycles of treatment. No deep vein thrombosis, cardiac toxicity or renal toxicity occurred during the treatment process. Conclusions:The ZR2 regimen is effective in the treatment of elderly DLBCL patients with tolerable adverse reactions.

Objective:To investigate the mechanism of benzyl isothiocyanate(BITC) in the treatment of anaplastic thyroid cancer(ATC).Methods:Using network pharmacological analysis, key targets of BITC and ATC were screened, followed by GO and KEGG enrichment analysis. In order to validate the findings, AutoDock software was used to dock BITC and ATC key targets. BITC was applied to two ATC cell lines(8505C and CAL-62). Flow cytometry was used to analyze cell apoptosis. Autophagy inhibitors hydroxychloroquine sulfate(HCQ) and 3-methyladenine(3MA) were used in combination with BITC. Real-time quantitative PCR was conducted to detect the gene level of LC3B, while Western blotting was utilized to examine the expression of NF-κB, LC3B Ⅱ, Beclin-1, and Bcl-2. In animal experiments, a mouse tumor model was constructed using CAL-62 cells, treated with intraperitoneal injections of BITC(100 mg/kg) and normal saline respectively, administered every other day for a total of 21 days. Immunoblotting of tumor tissue was performed to detect the expression of LC3B Ⅱ, Bcl-2, Beclin-1, and NF-κB.Results:A total of 10 key targets with binding energies≤-4.0 kcal/mol were identified. KEGG analysis showed that these genes are mainly involved in NF-κB signaling pathway and apoptosis. BITC inhibited ATC cells with IC50 values of 27.56 μmol/L for 8505C and 28.30 μmol/L for CAL-62. The expression levels of NF-κB, Beclin-1, and Bcl-2 decreased, while LC3B Ⅱ and LC3B gene expression increased. Combining 3MA with BITC enhanced cell inhibition LC3B Ⅱ expression. HCQ increased LC3B Ⅱ expression without enhancing cell and viability inhibition. In the mouse tumor model, compared to the control group, the treatment group had higher LC3B Ⅱ and lower Bcl-2, Beclin-1, and NF-κB levels.Conclusion:BITC could inhibit the growth of ATC cells in vitro and in vivo, disrupt the autophagy degradation, and inhibit the NF-κB pathway.

Objective:To investigate the value of serum miR-145 and matrixmetallo proteinase-2 (MMP-2) levels in predicting pathologic complete response (pCR) after neoadjuvant chemotherapy in triple-negative breast cancer.Methods:125 patients with triple-negative breast cancer who received neoadjuvant chemotherapy in the Hospital from Jan. 2022 to Dec. 2023 were prospectively included as the study objects, and 130 healthy people matching the age of the case group who underwent physical examination in our hospital during the same period were included as the healthy control group. Real-time fluorescence quantitative polymerase chain reaction was used to detect the serum miR-145 level of all subjects. Serum MMP-2 levels were determined by enzyme-linked immunosorbent assay (ELISA). After neoadjuvant chemotherapy, patients were evaluated according to Miller-Payne (MP) grading criteria and divided into pCR group and non-PCR group.Results:The serum miR-145 level in patients with tertiary breast cancer was 1.49±0.27, which was significantly lower than that in healthy control group (2.79±0.49), with statistical significance ( t=20.33, P<0.001). The serum MMP-2 level in triple negative breast cancer patients was (153.07±38.36) ng/mL, which was significantly higher than that in healthy control group (84.38±12.63) ng/mL, and the difference was statistically significant ( t=26.13, P<0.001). After neoadjuvant chemotherapy, the serum miR-145 level in non-PCR patients before treatment was 1.36±0.21, which was significantly lower than that in pCR group (1.74±0.20), with statistical significance ( t=9.93, P<0.001). After neoadjuvant chemotherapy, the serum MMP-2 level in non-PCR patients before treatment was (169.57±30.45) ng/mL, which was significantly higher than that in pCR group (121.61±31.79) ng/mL, and the difference was statistically significant ( t=8.24, P<0.001). Pearson correlation analysis showed that there was a significant negative correlation between serum miR-145 and MMP-2 levels in patients with triple-negative breast cancer before treatment ( r=-0.47, P<0.001). ROC curve analysis results showed that serum miR-145 and MMP-2 levels before treatment predicted the sensitivity and specificity of pCR after neoadjuvant chemotherapy for triple-negative breast cancer were 82.9% and 74.4%, 45.1% and 99.8%, respectively. The sensitivity and specificity of pCR after neoadjuvant chemotherapy for triple-negative breast cancer were 84.1% and 88.4%, respectively. Conclusion:Serum miR-145 and MMP-2 levels are related to the efficacy of neoadjuvant chemotherapy in patients with triple-negative breast cancer, and the combined application of the two has certain predictive value.
