RESUMEN
BACKGROUND: Salivary Adenoid Cystic Carcinoma (ACC) is characterized by a highly invasive and slow-growing pattern, and its etiology remains unidentified. Triptonide (TN) has demonstrated efficacy as a pharmacotherapeutic agent against ACC. Nonetheless, the specific targets and mechanism of molecular action underlying the effectiveness of TN in treating ACC have not been elucidated. OBJECTIVES: By integrating network pharmacology with in-laboratory experiments, this research delves into the prospective targets and molecular mechanisms associated with the application of TN in treating ACC. METHODS: Initially, pertinent targets associated with TN against ACC were acquired from public databases. Subsequently, a combination of network pharmacology and bioinformatics analysis was utilized to screen the top 10 hub targets and key signal pathways of TN-treating ACC. Finally, in vitro experiments involving various molecular assays were conducted to evaluate the biological phenotypes of cells following TN treatment, encompassing assessments of apoptosis levels, plate migration, and other parameters, thereby validating pivotal genes and pathways. RESULTS: A total of 23 pertinent targets for TN in relation to ACC were identified, with the top 10 hub genes being MAPK8, PTGS2, RELA, MAPK14, NR3C1, HDAC1, PPARG, NFKBIA, AR, and PGR. There was a significant correlation between the TNF signaling pathway and the treatment of ACC with TN. In vitro experiments demonstrated that TN treatment elevated RELA phosphorylation while concurrently reducing MAPK14 phosphorylation and inducing G2/M arrest. TN exhibited the ability to enhance the apoptosis rate through increased caspase-3 activity, elevated levels of Reactive Oxygen Species (ROS), mitochondrial dysfunction, and inhibition of cell migration. CONCLUSION: There is a potential therapeutic role for TN in the treatment of ACC through the activation of the TNF signaling pathway. Among the identified candidates, MAPK8, HDAC1, PTGS2, RELA, NR3C1, PPARG, NFKBIA, AR, and PGR emerge as the most pertinent therapeutic targets for TN in the context of ACC treatment.
RESUMEN
Tribbles pseudokinase 3 (TRIB3) has been identified recently as a novel oncogene in several cancers. Still, further extensive research is imperative to elucidate its function and the molecular mechanisms underlying its involvement in the progression of head and neck squamous cell carcinoma (HNSCC). In our study, we found that TRIB3 silencing significantly promoted cell death by inducing ferroptosis. The interaction of TRIB3 with Transcription Factor 4 (TCF4) and ß-catenin created a heterotrimeric complex, which directly interacts with the ALOXE3 promoter, detrimentally impacting its activation. The consequential partial neutralization of ferroptosis induced by TRIB3 deficiency is observed through the implementation of ALOXE3 knockdown. Furthermore, the study demonstrated that the molecular inhibitor hesperidin, targeting TRIB3, not only reduced cell malignancy but also induced ferroptosis, thereby suppressing tumor growth. Overall, our findings unequivocally validate the proposition that TRIB3 deficiency precipitates the iron death mechanism, thereby indicating that the strategic targeting of TRIB3 could emerge as an innovative therapeutic strategy for HNSCC.

INTRODUCTION: The therapy of rheumatoid arthritis (RA) was advanced by biological agents, yet costly. This study aims to identify the effective threshold dose of etanercept (ENT) and cost-effectiveness in methotrexate (MTX)-resistant RA in real world. METHODS: Eligible patients had an inadequate response (DAS28-ESR > 3.2) to initial MTX monotherapy, and subsequently received etanercept. The effective cut-off value of cumulative dose was identified to maintain remission response (DAS28-ESR < 2.6) at month 24 by using restricted cubic splines. Remission rate, low disease activity (LDA) rate, glucocorticoid exposure, safety, and cost-effectiveness were compared between the saturated and non-saturated dose groups divided by the cut-off dose. RESULTS: Seventy-eight (14.2%) of 549 enrolled patients were eligible, and 72 patients completed follow-up. The 2-year cumulative cut-off dose that maintained remission response at 24 months was 1975 mg. And the recommended threshold dosing strategy of etanercept was twice weekly (BIW) for the first 6 months, every week (QW) for the next 6 months, and every 2 weeks (Q2W) and every month (QM) for the second year. Greater net changes in DAS28-ESR score were observed in the ENT saturated dose group than in the non-saturated dose group (average change 0.569, 95%CI 0.236-0.901, p = 0.001). The proportion of patients achieving remission (27.8% vs 72.2%, p < 0.001) and LDA (58.3% vs 83.3%, p = 0.020) in the non-saturated group was both significantly lower than that in the saturated group at 24 months. The incremental cost-effectiveness ratio of the saturated group referred to the non-saturated group was 5791.2 $/QALY. CONCLUSIONS: In refractory RA patients, the effective cumulative cut-off dose of etanercept for sustained remission at 24 months was calculated as 1975 mg, and receiving saturated dose was more effective and cost-effective than with non-saturated dose. Key Points ⢠The effective cumulative cut-off dose of etanercept for sustained remission at 24 months in RA patients is calculated as 1975 mg. ⢠Receiving saturated dose of etanercept is more effective and cost-effective than with non-saturated dose in refractory RA patients.

The recently described role of RNA methylation in regulating immune cell infiltration into tumors has attracted interest, given its potential impact on immunotherapy response. YTHDF1 is a versatile and powerful m6A reader, but the understanding of its impact on immune evasion is limited. Here, we reveal that tumor-intrinsic YTHDF1 drives immune evasion and immune checkpoint inhibitor (ICI) resistance. Additionally, YTHDF1 deficiency converts cold tumors into responsive hot tumors, which improves ICI efficacy. Mechanistically, YTHDF1 deficiency inhibits the translation of lysosomal genes and limits lysosomal proteolysis of the major histocompatibility complex class I (MHC-I) and antigens, ultimately restoring tumor immune surveillance. In addition, we design a system for exosome-mediated CRISPR/Cas9 delivery to target YTHDF1 in vivo, resulting in YTHDF1 depletion and antitumor activity. Our findings elucidate the role of tumor-intrinsic YTHDF1 in driving immune evasion and its underlying mechanism.

OBJECTIVE: To evaluate the risk of major infections and the relationship between major infections and mortality in patients with newly diagnosed SLE. METHODS: A newly diagnosed (<3 months) hospitalised Systemic Lupus Inception Cohort (hSLIC) in our centre during 1 January 2013 and 1 November 2020 was established. All patients were followed up for at least 1 year or until death. Patient baseline characteristics were collected. Major infection events were recorded during follow-up, which were defined as microbiological/clinical-based diagnosis treated with intravenous antimicrobials. The cohort was further divided into a training set and a testing set. Independent predictors of major infections were identified using multivariable logistic regression analysis. Kaplan-Meier survival analyses were conducted. RESULTS: Among the 494 patients enrolled in the hSLIC cohort, there were 69 documented episodes of major infections during the first year of follow-up in 67 (14%) patients. The major infection events predominantly occurred within the first 4 months since enrolment (94%, 65/69) and were associated with all-cause mortality. After adjustments for glucocorticoid and immunosuppressant exposure, a prediction model based on SLE Disease Activity Index >10, peripheral lymphocyte count <0.8×109/L and serum creatinine >104 µmol/L was established to identify patients at low risk (3%-5%) or high risk (37%-39%) of major infections within the first 4 months. CONCLUSIONS: Newly onset active SLE is susceptible to major infections, which is probably due to underlying profound immune disturbance. Identifying high-risk patients using an appropriate prediction tool might lead to better tailored management and better outcome.

Vasculogenic mimicry (VM) is a kind of tumor vasculature providing blood supply for tumor growth, and the formation of VM is independent of vascular endothelial cells. Instead, VM structures are formed by differentiated tumor cells such as nasopharyngeal carcinoma cells. Recently, studies have shown that anti-angiogenic therapy failed to improve the overall survival for patients, namely, nasopharyngeal carcinoma patients. The existence of VM structure is probably one of the reasons for resistance for anti-angiogenic therapy. Therefore, it is important to study the mechanism for VM formation in nasopharyngeal carcinoma. In this study, the bioinformatic analysis revealed that microRNA-125a-3p (miR-125a) was highly expressed in normal nasopharyngeal epithelial tissue than in nasopharyngeal carcinoma. An in vitro study demonstrated that miR-125a plays an inhibitory role in nasopharyngeal carcinoma cell migration and VM formation, and further studies confirmed that TAZ is a direct downstream target for miR-125a. On this basis, we artificially engineered human mesenchymal stem cells (MSCs) to generate exosomes with high miR-125a expression. Treatment with these miR-125a-over-expressing exosomes attenuated the migration and VM formation in nasopharyngeal carcinoma cells. In addition, the inhibitory role of these exosomes on VM formation and migration in nasopharyngeal carcinoma was also confirmed in vivo. Overall, the current study shows that MSCs can be utilized to generate exosomes with high miR-125a level, which could be therapeutic nanoparticles targeting VM formation in nasopharyngeal carcinoma and used as a complement to anti-angiogenic therapy in the future.
RESUMEN
OBJECTIVES: Low disease activity status and remission are crucial treat-to-target (T2T) endpoints in systemic lupus erythematosus (SLE). To evaluate the efficacy of metformin add-on in attaining T2T among Chinese patients with mild-to-moderate lupus, a post-hoc analysis combining our previous two randomised trials was carried out. METHODS: Data from the open-labeled proof-of-concept trial (ChiCTR-TRC-12002419) and placebo-controlled trial (NCT02741960) were integrated together. Disease flares were compared between patients attaining T2T or not at baseline. The efficacy of metformin versus placebo/nil add-on to standard therapy in SLE patients who did not meet the T2T criteria at baseline was evaluated in terms of attaining T2T at 12-month follow-up. RESULTS: Of 253 SLE patients, 43.8% (n=89) attained T2T at baseline. During the 12 months, 15 patients flared in the T2T group, which was significantly lower than that in the non-T2T group (16.9% vs. 36.0%, p=0.001). For 164 patients who did not meet the T2T criteria at entry, 59.0% and 43.6% of the 78 patients taking metformin in this population attained the lupus low disease activity status (LLDAS) and remission endpoints at last visit, respectively, as compared to 37.2% and 24.4% of the 86 patients in the placebo/nil group (LLDAS p=0.008; remission p=0.013). Over time, metformin helped patients achieving T2T earlier and maintain longer T2T duration over placebo/nil (LLDAS duration: 44.9% vs. 26.4%, p=0.002; remission duration:19.1% vs. 10.7%, p=0.014). CONCLUSIONS: This post-hoc analysis suggested that metformin might be an adjuvant therapy in achieving treat-to-target in SLE patients.

PURPOSE: To compare the efficacy, safety, and cost-effectiveness of methotrexate (MTX) plus hydroxychloroquine (HCQ) vs MTX plus leflunomide (LEF) in established rheumatoid arthritis (RA) with inadequate response to MTX monotherapy in a real-world Chinese cohort. PATIENTS AND METHODS: A prospective RA cohort (n=549) was screened with eligible patients who had inadequate response (disease activity score in 28 joints using erythrocyte sedimentation rate, DAS28-ESR>3.2) to initial MTX monotherapy and subsequently received either MTX+HCQ or MTX+LEF. Propensity score matching (PSM) was applied to adjust the possible baseline confounders between two groups. The primary outcome was the proportion of patients achieving first remission (DAS28-ESR<2.6) during follow-up by log rank test. Secondary outcomes were changes of DAS28, glucocorticoids (GCs) exposure, safety, cost-effectiveness, sustained remission, and low disease activity (LDA) rate after 24-month follow-up. RESULTS: Overall, 222 eligible patients were subjected to the aforementioned two treatment protocols (MTX+HCQ, n=102; MTX+LEF, n=120). After PSM adjustment, 97 patients in each group were analyzed. A higher remission rate was observed in the MTX+HCQ group than in the MTX+LEF group (70.1% vs 56.7%, P=0.048). The median time to remission was 11 and 16 months in the two groups, respectively. At the endpoint, more patients achieved remission (46.8% vs 32.5%, P=0.063) and maintained sustained LDA in the HCQ group (53.2% vs 38.6%, P=0.062) and also more patients withdrew GCs in this group (32% vs 16.7%, P=0.053) than those in the LEF group. Safety profiles were non-alarming, with no significant difference between the two groups. The incremental cost-effectiveness ratio yielded by MTX+HCQ over MTX+LEF was $1,111.8 per quality-adjusted life-year (QALY), within the cost-effective threshold set as the per capita gross domestic product (GDP) of China. CONCLUSION: The MTX+HCQ combination was seemingly superior to MTX+LEF in a real-world cohort of Chinese RA patients with inadequate response to methotrexate monotherapy in respect of the efficacy and cost-effectiveness.
RESUMEN
OBJECTIVE: To confirm that metformin prevents flares in patients with SLE with low disease activity, we performed a post hoc analysis combining our previous two randomised trials. METHODS: Post hoc analyses were performed on data from the open-labelled proof-of-concept trial (n=113, ChiCTR-TRC-12002419) and placebo-controlled 'Met Lupus' trial (n=140, NCT02741960) comparing the efficacy of metformin versus placebo/nil add-on to standard therapy in patients with SLE with low disease activity (SELENA-SLEDAI ≤4). The primary endpoint was defined by the SELENA-SLEDAI Flare Index at 12-month follow-up. A subgroup analysis was performed. RESULTS: Overall, 201 eligible patients were included, with 99 allocated to metformin group and 102 allocated to the placebo/nil group. By 12 months of follow-up, 21 patients (21.2%) flared in the metformin group, as compared with 36 (35.3%) in the placebo/nil group (p=0.027, risk ratio=0.68, 95% CI 0.46 to 0.96). Subgroup analysis showed that patients with negative anti-dsDNA antibody and normal complement at baseline, and a disease duration <5 years with concomitant use of hydroxychloroquine had a better response to metformin. CONCLUSION: Post hoc pooled analyses suggested that metformin reduced subsequent disease flares in patients with SLE with low disease activity, especially for serologically quiescent patients.

Immune thrombocytopenia (ITP) is a common complication of connective tissue diseases (CTD). However, refractory and recurrent cases are frequent, who often need intensive immunotherapy. In the real world to compare the efficacy and safety of two common options, rituximab (RTX) and cyclosporine (CsA), in patients with refractory CTD-ITP, we conducted this retrospective study. Inpatients diagnosed with CTD-ITP who experienced treatment failure with initial prednisone or other immunosuppressants and who subsequently received either RTX or CsA between 2013 and 2018 were identified. All the patients were followed up for at least 6 months. Remission was defined as sustained platelet count ≥ 50 × 10^9/L, where ≥ 100 × 10^9/L was considered complete remission and 50-100 × 10^9/L was considered partial remission. Propensity score weighting analysis was performed to balance the confounders as indication. A total of 83 patients with CTD-ITP were identified, of whom 43 had systemic lupus erythematosus, 24 had undifferentiated CTD, and 16 had primary Sjogren syndrome. The RTX group (n = 53) had a much higher remission rate than the CsA group (n = 30) after 3 months and throughout the following 3 months (3 m, 86.8% vs 63.6%, p = 0.025; 6 m, 81.8% vs 53.5%, p = 0.011). Binary logistic regression analysis confirmed that treatment with RTX predicted better outcome (OR 4.09, 1.42 ~ 11.79), while age > 50 (OR 0.31, 0.11 ~ 0.93) was a risk factor. Furthermore, we reinforced the conclusions by propensity score weighting analysis (RTX OR 4.89, 1.64 ~ 14.58; age > 50 OR 0.31, 0.12 ~ 0.83). In our real-world retrospective study, for patients with refractory CTD-ITP, RTX was superior to CsA in terms of the durable remission rate. Key Points: ⢠Refractory cases are common in patients with immune thrombocytopenia secondary to connective tissue diseases (CTD-ITP), requiring intensive immunotherapy. ⢠Randomized controlled trials comparing rituximab and a traditional immunosuppressive agents (IS), such as cyclosporin, are lacking in these patients. ⢠Our real-word retrospective study indicated that rituximab was superior to cyclosporin in patients with refractory CTD-ITP.

BACKGROUND: Immunometabolism is involved in the pathogenesis of systemic lupus erythematosus (SLE). The aim of this study was to repurpose metformin, an anti-diabetic drug that regulates systemic and cellular metabolism, and assess its effects in Chinese patients with SLE without diabetes. METHODS: We did a multicentre, randomised, double-blind, placebo-controlled trial in three hospitals in Shanghai, China. We enrolled adult patients with SLE, without diabetes, who had Safety of Estrogens in Lupus Erythematosus National Assessment-Systemic Lupus Erythematosus Disease Activity Index (SELENA-SLEDAI) scores no higher than 6; with no A score or no more than one B score on the British Isles Lupus Assessment Group (BILAG) scale at screening; who had had at least one lupus flare; and were treated with prednisone (≥20 mg per day) within the preceding 12 months. Patients were randomly assigned (1:1) in blocks of four by a computer algorithm to add metformin tablets (250 mg per tablet with a target dose of 0·5 g three times per day; metformin group) or placebo tablets (placebo group) to their standard therapy, for a maximum of 12 months. Patients, assessment staff, and statisticians were masked to group assignment. The primary endpoint was a composite index of major or mild-to-moderate disease flares (SELENA-SLEDAI Flare Index) at 12 months. The full analyses were done in all patients who received at least one dose of the study drug using the χ2 test. Adverse events were recorded during the 12-month follow-up. This study is registered with ClinicalTrials.gov, NCT02741960. FINDINGS: Between May 24, 2016, and Dec 13, 2017, 180 patients were screened, of whom 140 (78%) of them were enrolled. 31 (17%) did not meet the inclusion criteria and nine (5%) withdrew informed consent without treatment after randomisation. 67 patients were assigned to the metformin group and 73 to the placebo group. By 12 months of follow-up, there was no significant difference in the incidence of lupus flares, which occurred in 14 (21%) patients in the metformin group versus 25 (34%) in the placebo group (relative risk 0·68, 0·42-1·04, p=0·078). Patients receiving metformin experienced more gastrointestinal adverse events (three [4%] discontinued for this reason vs one [1%] for placebo; overall 26 [39%] vs 11 [15%], p=0·0015), but the incidence of non-flare serious adverse events was similar between groups (one [1%] vs three [4%], p=0·35). The frequency of infection events was significantly lower in patients in the metformin group than in the placebo group (17 [25%] vs 32 [44%], p=0·022). No patients died as a result of treatment. INTERPRETATION: This trial was underpowered to draw a sound conclusion on the efficacy of metformin to reduce disease flares as an add-on treatment to standard care in patients with SLE. Nonetheless, metformin had a favourable safety profile and our data present a basis for larger trials to investigate its potential effect on reducing the frequency of flares for patients with SLE with low-grade disease activity who are at risk of relapse.

RESUMEN
BACKGROUND: To explore the inadequacies of health service and its impact on clinical outcomes of patients with systemic lupus erythematosus (SLE) in China. METHODS: A total of 210 SLE patients were randomly recruited between January 2017 and January 2018. Each patient received self-report questionnaires to assess medication adherence [Compliance Questionnaire for Rheumatology (CQR)], beliefs about medicines [Beliefs about Medicines Questionnaire (BMQ)] and satisfaction about medicine information [the Satisfaction with Information about Medicines Scale (SIMS)]. Associations between SLE disease activity index (SLEDAI-2 K) and observed factors were analyzed by multiple logistic regression. RESULTS: Based on CQR, only 28.10% patients were adherent. The score of BMQ was 2.85 ± 5.42, and merely 32.38% patients were satisfied with the information about their prescribed medicines. Disease activity was associated with SIMS, EuroQol five-dimensions [EQ5D], Systemic Lupus International Collaborating Clinics (SLICC), depression, use of NSAID (P ≤ 0.05). Remission of disease was positively correlated with SIMS (OR = 0.16, 95% CI: [0.06, 0.40]), and BMQ (OR = 0.64, 95%CI: [0.43, 0.94]). CONCLUSION: In this study, the scores of BMQ and SIMS were low, implying defects in the patient education of health service system, which led to disease flare in Chinese SLE patients. TRIAL REGISTRATION: ClinicalTrials.gov ID: NCT03024307 . Registered January 18, 2017.

Background For the large number of systemic lupus erythematosus (SLE) patients in China, it is critical to carry out effective disease management to improve the treatment effect and reduce disease burden. A pharmacist-led multidisciplinary care model has not been reported in Chinese SLE patients before. Objective To assess the effect of patient-centered, pharmacist-led, multidisciplinary care on clinical outcomes and satisfaction with health care in Chinese SLE patients. Setting: The South Campus, Renji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China. Method Participants were 143 systemic lupus erythematosus patients randomly assigned to either the intervention group (multidisciplinary care: physician, pharmacist and nurse) or the control group (usual care only). Main outcome measures The primary outcome was scores on the systemic lupus erythematosus disease activity index-2000, the satisfaction with information about medicines scale, and the EuroQol five-dimension questionnaire, assessed at baseline and 12 months. Results Between October 1, 2017 and October 1, 2018, 42 participants were included in the intervention group and 40 in the control group. At 12 months, results for the systemic lupus erythematosus disease activity index-2000 differed significantly between the intervention group and the control group (0 vs. 2, P = 0.027). Patient satisfaction with health care was also significantly greater in the intervention group than in the control group (92.9 vs. 0%, P = 0.000). According to the EuroQol five-dimension questionnaire, health quality was also improved (0.94 vs. 0.85, P = 0.006). Conclusion Our multidisciplinary care team significantly improved clinical outcomes and satisfaction with drug information in Chinese systemic lupus erythematosus patients.

PURPOSE: The aim of this study was to develop and internally validate a medication nonadherence risk nomogram in a Chinese population of patients with inflammatory rheumatic diseases. PATIENTS AND METHODS: We developed a prediction model based on a training dataset of 244 IRD patients, and data were collected from March 2016 to May 2016. Adherence was evaluated using 19-item Compliance Questionnaire Rheumatology. The least absolute shrinkage and selection operator regression model was used to optimize feature selection for the medication nonadherence risk model. Multivariable logistic regression analysis was applied to build a predicting model incorporating the feature selected in the least absolute shrinkage and selection operator regression model. Discrimination, calibration, and clinical usefulness of the predicting model were assessed using the C-index, calibration plot, and decision curve analysis. Internal validation was assessed using the bootstrapping validation. RESULTS: Predictors contained in the prediction nomogram included use of glucocorticoid (GC), use of nonsteroidal anti-inflammatory drugs, number of medicine-related questions, education level, and the distance to hospital. The model displayed good discrimination with a C-index of 0.857 (95% confidence interval: 0.807-0.907) and good calibration. High C-index value of 0.847 could still be reached in the interval validation. Decision curve analysis showed that the nonadherence nomogram was clinically useful when intervention was decided at the nonadherence possibility threshold of 14%. CONCLUSION: This novel nonadherence nomogram incorporating the use of GC, the use of nonsteroidal anti-inflammatory drugs, the number of medicine-related questions, education level, and distance to hospital could be conveniently used to facilitate the individual medication nonadherence risk prediction in IRD patients.
