The ADAM17 inhibitor ZLDI-8 sensitized hepatocellular carcinoma cells to sorafenib through Notch1-integrin ß-talk.

ZLDI-8 is an A disintegrin and metalloproteinase domain 17 (ADAM17) inhibitor that suppresses the shedding of Notch1 to the Notch1 intracellular domain (NICD). In previous studies, we found that ZLDI-8 was able to sensitize HCC to sorafenib, but the mechanism of action remains unclear. The sensitizing effects of ZLDI-8 were tested both in vitro and in vivo. EMT-related factors, sorafenib sensitivity-related proteins and ECM-related gene expression were assessed using immunohistochemistry, RTPCR and Western blotting. Knockdown assays were conducted to determine the relationship between the Notch and Integrin pathways. CoIP assays, nuclear and cytoplasmic fractionation and immunofluorescence colocalization were applied to explore the interaction between the Notch and Integrin pathways. Appropriate statistical analysis methods were used to assess the significance of the experimental results and to ensure the scientific validity and reliability of the experimental design. We found that ECM- and EMT-related proteins were downregulated after ZLDI-8 treatment (P<0.05). ZLDI-8 significantly downregulated Integrinß1 and Integrinß3 in HCC in vitro and in vivo (P<0.05), possibly through Foxc2-dependent regulation. Mechanistically, interfering with the expression of both Integrin-linked kinase (ILK) and the NICD may downregulate the expression of proteins targeted by sorafenib, thereby sensitizing cells to sorafenib. The retroregulation of Integrinß by ILK may occur through the interaction between the NICD and ILK and may be the result of the translocation of the complexus. Our study indicates that blocking the Notch pathway may affect Integrinß through crosstalk between the Notch1 and Integrinß/ILK signaling pathways, thus providing a potential therapeutic strategy for HCC.

Incidence of renal cell carcinoma after solid organ transplantation: a systematic review and meta-analysis.

BACKGROUND: The incidence rate of malignant tumors after solid organ transplantation is higher than the normal population. The aim of our study is to identify the risk of renal cell carcinoma (RCC) after liver, kidney, heart and lung transplantation, respectively, and suggest that transplant patients can be screened early for tumors to avoid risk. METHODS: PubMed, Embase and the Cochrane Library from their inception until August 16,2023. Retrospective and cohort studies which focus on the statistical data of standardized incidence ratios (SIRs) of RCC after solid organ transplantation (SOT) more than one year have been included and extracted. The study was registered with PROSPERO, CRD4202022343633. RESULTS: Sixteen original studies have been included for meta-analysis. Liver transplantation could increase the risk of RCC (SIR = 0.73, 95%CI: 0.53 to 0.93) with no heterogeneity(P = 0.594, I2 = 0.0%). And kidney transplantation could increase the risk of RCC(8.54, 6.68 to 10.40; 0.000,90.0%). Besides, heart and lung transplantation also could increase the risk of RCC(SIR = 0.73, 95%CI: 0.53 to 0.93; SIR = 1.61, 95%CI:0.50 to 2.71). Moreover, significance could also be found in most subgroups, especially the European group and retrospective study group. What's more, after removing studies which have a greater impact on the overall outcome in RCC rate after kidney transplantation, heterogeneity did not solve and significant different was also observed in the European group (7.15, 5.49 to 8.81; 0.000, 78.6%). CONCLUSION: Liver, kidney, heart and lung transplantation patients have an increased risk of processing RCC compared to the general population and most subgroups, especially in geographic location of European subgroup, which suggested that patients should be screened frequently after transplantation.

An integrated multi-omics approach revealed the regulation of melatonin on age-dependent mitochondrial function impair and lipid dyshomeostasis in mice hippocampus.

Melatonin can improve mitochondrial dysfunction associated with the aging process by removing active oxygen, as well as inhibiting lipid peroxidation to maintain biofilm fluidity and resist free radical attack. However, there is poor understanding of the effect of melatonin on age-dependent mitochondrial function and lipid profile changes in brain. In this study, we investigated the energy metabolism of the whole body and brain of mice at 9 months, 13 months, and 25 months of continuous gastric administration of 3 mg/kg/d melatonin once per day morning for two months. In addition, we performed transcriptomic, proteomic and lipidomic analysis in the hippocampus of mice at different ages. Proteomics showed that melatonin regulated mitochondrial electron transport and leucine degradation in mouse hippocampus. Lipomics suggested that the long-chain unsaturated glycerol phospholipids in mouse hippocampus increased in an age-dependent manner, while ceramide and glycerol phospholipids decreased significantly in hippocampus of mouse chronically exposed to melatonin. The combined analysis of proteome and liposome demonstrated that Mpst, Ccsap, Hdhd5, Rpl5 and Flna were the key proteins of the network which involved in the regulation of numerous lipids. Furthermore, ultrastructure observation results illustrated that melatonin could improve the damaged mitochondrial and morphologies of 25-month-old mice hippocampus. In conclusion, we describe a mechanism that age-dependent up-regulation of long-chain unsaturated lipids is a driving risk factor for mitochondrial damage and this effect could be reversed by chronic supplement of low-dose melatonin.

Diagnostic accuracy and prognostic significance of osteopontin in liver cirrhosis and hepatocellular carcinoma: a Meta-analysis.

OBJECTIVE: At present, there is no definite suggestion about effective tumour biomarkers for the diagnostic accuracy and prognostic significance of hepatocellular carcinoma (HCC) and liver cirrhosis (LC). The aim of our research was to determine the value of the tumour biomarker osteopontin (OPN), which is encoded by the Spp1 gene, in the diagnosis, prognosis and development of HCC and LC through meta-analysis. METHODS: A systematic literature search was performed in the PubMed, Embase, Cochrane Library and China National Knowledge Infrastructure electronic databases up to March 2021. Studies evaluating the diagnostic and/or prognostic value of OPN in HCC and/or LC were included. RESULTS: From the systematic search, 35 studies including 9150 participants were eligible, 25 of which provided data on the diagnostic value of OPN overexpression, while 15 studies provided data on the prognostic value. OPN had high diagnostic accuracy in both HCC and LC patients compared with healthy controls, and the diagnostic efficiency was increased by the biomarker combination OPN + AFP. CONCLUSIONS: OPN may be adopted as a promising predictive tumour biomarker for the diagnosis and prognosis of HCC and LC and may be a potential therapeutic target.

Does coffee, tea and caffeine consumption reduce the risk of incident breast cancer? A systematic review and network meta-analysis.

OBJECTIVE: We aimed to evaluate the association between coffee and/or tea consumption and breast cancer (BC) risk among premenopausal and postmenopausal women and to conduct a network meta-analysis. DESIGN: Systematic review and network meta-analysis. SETTING: We conducted a systematic review of electronic publications in the last 30 years to identify case-control studies or prospective cohort studies that evaluated the effects of coffee and tea intake. RESULTS: Forty-five studies that included more than 3 323 288 participants were eligible for analysis. Network meta-analysis was performed to determine the effects of coffee and/or tea consumption on reducing BC risk in a dose-dependent manner and differences in coffee/tea type, menopause status, hormone receptor and the BMI in subgroup and meta-regression analyses. According to the first pairwise meta-analysis, low-dose coffee intake and high-dose tea intake may exhibit efficacy in preventing ER(estrogen receptor)- BC, particularly in postmenopausal women. Then, we performed another pairwise and network meta-analysis and determined that the recommended daily doses were 2-3 cups/d of coffee or ≥5 cups/d of tea, which contained a high concentration of caffeine, particularly in postmenopausal women. CONCLUSIONS: Coffee and tea consumption is not associated with a reduction in the overall BC risk in postmenopausal women and is associated with a potentially lower risk of ER- BC. And the highest recommended dose is 2-3 cups of coffee/d or ≥5 cups of tea/d. They are potentially useful dietary protectants for preventing BC.

PI3K/AKT/mTOR pathway-related long non-coding RNAs: roles and mechanisms in hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is one of the most common tumors worldwide with high prevalence and lethality. The oncogenic phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/AKT/mTOR) pathway is a classic dysregulated pathway involved in the pathogenesis of HCC. However, the underlying mechanism for how PI3K/AKT/mTOR pathway aberrantly activates HCC has not been entirely elucidated. The recognition of the functional roles of long non-coding RNAs (lncRNAs) in PI3K/AKT/mTOR signaling axis sheds light on a new dimension to our understanding of hepatocarcinogenesis. In this review, we comprehensively summarize 67 dysregulated PI3K/AKT/mTOR pathway-related lncRNAs in HCC. Many studies have indicated that the 67 dysregulated lncRNAs show oncogenic or anti-oncogenic effects in HCC by regulation on epigenetic, transcriptional and post-transcriptional levels and they play pivotal roles in the initiation of HCC in diverse biological processes like proliferation, metastasis, drug resistance, radio-resistance, energy metabolism, autophagy and so on. Besides, many of these lncRNAs are associated with clinicopathological features and clinical prognosis in HCC, which may provide a potential future application in the diagnosis and therapy of HCC.

What intervention regimen is most effective prevention for Portal venous system thrombosis after splenectomy in cirrhotics patients with Portal hypertension? Systematic review and network meta-analysis.

Portal venous system thrombosis (PVST) is a life-threatening complication after splenectomy in cirrhotics patients with portal hypertension, while the application of intervention regimen may prevent the incidence of PVST. The aim of this network meta-analysis was to determine the most appropriate intervention regimen and application time. Several electronic databases were searched up to December 2019. We estimated summary odds ratios (OR) using pairwise and network meta-analyses with random effects for the outcome of occurrence of PVST. This work was registered with PROSPERO (CRD42019161406). The analysis was based on 19 researches, which included 1853 patients. The results drawn from the data in standard meta-analysis indicated that the application of intervention was better than no intervention use, and early application of interventions was better than delayed application in preventing the occurrence of PVST. Subsequent network meta-analysis was performed to determine the most suitable intervention regimen used early post-operation. For separate mono-therapy drug, alprostadil, antithrombin III, low molecular dextran were significantly more efficacious than others. However, mono-therapy analysis was not so close to clinical application. In the follow-up network meta-analysis, low molecular dextran combined with low molecular weight heparin exhibited the largest effect on the preventing the incidence of PVST (0.12, 0.03-0.49), followed by antithrombin III (0.12, 0.04-0.41) with low molecular dextran (0.14, 0.05-0.41). We could draw the conclusion that early application of low molecular weight heparin combined with low molecular dextran seems to be the most satisfactory treatment to prevent the incidence of PVST for patients with cirrhotic portal hypertension after splenectomy.

Novel ADAM-17 inhibitor ZLDI-8 inhibits the proliferation and metastasis of chemo-resistant non-small-cell lung cancer by reversing Notch and epithelial mesenchymal transition in vitro and in vivo.

Acquired drug-resistant non-small cell lung cancer (NSCLC) has strong proliferation ability and is prone to epithelial-mesenchymal transition (EMT) and subsequent metastasis. Notch pathway mediates cell survival and EMT and is involved in the induction of multidrug resistance (MDR). ZLDI-8 is an inhibitor of Notch activating/cleaving enzyme ADAM-17 we found before. However, the effects of ZLDI-8 on resistant NSCLC was unclear. Here, we demonstrated for the first time that ZLDI-8 could induce apoptosis in lung cancer, especially in chemotherapy-resistant non-small cell lung cancer cells, and also inhibit migration, invasion and EMT phenotype of drug-resistant lung cancer. ZLDI-8 inhibits the Notch signaling pathway, thereby regulating the expression of survival/apoptosis and EMT-related proteins. Moreover, ZLDI-8 suppresses multidrug-resistant lung cancer xenograft growth in vivo and blocks metastasis in a tail vein injection mice model. Therefore, ZLDI-8 is expected to be an effective agent in the treatment of drug-resistant lung cancer.

Role of metformin in overweight and obese people without diabetes: a systematic review and network meta-analysis.

PURPOSE: Our aim was to assess the efficacy of metformin for weight loss in overweight and obese people through a systematic review and network meta-analysis and to identify the most suitable dosage and intervention period for using metformin in adolescents and adults. METHODS: We searched databases for studies published by April 2018. A total of 34 trials (44 analyses) involving 8461 participants and 16 intervention arms were eligible. The study was registered with PROSPERO International prospective register of systematic reviews (CRD42017081053). RESULTS: Metformin was found to significantly decrease body mass index percentile (BMI) and had a tendency to decrease BMI (kg/m2) and weight (kg). Significant efficacy was observed in many subgroups. The metaregression may have identified the causes of heterogeneity as metformin dosage, control type, and intervention period. Network meta-analysis revealed that in adolescents, intervention with 2000 mg/day metformin ranked better than other interventions; however, 1000 mg/day metformin for 3 months may be most suitable for adolescents. For adults, metformin at doses of 3000 and 1000 mg/day ranked the highest, other than minimeal and lifestyle interventions; moreover, intervention with 3000 mg/day for 6 months and 1000 mg/day for 0.5 months may be suitable for adults. CONCLUSION: When considering the efficacy of interventions for losing weight, metformin offers clear advantages for overweight and obese populations.

Which is the best combination of TACE and Sorafenib for advanced hepatocellular carcinoma treatment? A systematic review and network meta-analysis.

The aim of this study was to assess the comparative efficacy and safety of combination therapy with transarterial chemoembolization (TACE) and Sorafenib for patients with advanced hepatocellular carcinoma (HCC) through a systematic review and network meta-analysis and identify the best combination of TACE and Sorafenib. We searched databases for publications prior to May 2018. The prespecified efficacy outcomes were the objective response rate, overall survival rate, and time to progression. adverse effects included dermatologic, gastrointestinal, and general disorders. Subgroup analyses, meta-regression, and a network meta-analysis regarding two types of outcomes by different chemotherapy agents in TACE (5-fluorouracil, Adriamycin, Platinum, mitomycin C, hydroxycamptothecin) were included. The study is registered with PROSPERO (CRD42018098541). For efficacy outcomes, subgroups which included 5-fluorouracil and hydroxycamptothecin ranked higher than other chemotherapy agents, while mitomycin C ranked the lowest. For advanced effects, the use of mitomycin C or 5-fluorouracil as the chemotherapy agent ranked higher, while hydroxycamptothecin ranked the lowest. Therefore, we excluded 5-Fu and Mitomycin C in subsequent studies. Additionally, in the evaluation of primary adverse effects by the network meta-analysis, Platinum ranked the highest while hydroxycamptothecin ranked the lowest. Therefore, we excluded Platinum this time. Furthermore, all types of Adriamycin are not same, and some studies included two types of Adriamycin. The network meta-analysis results showed that the TACE (hydroxycamptothecin + pirarubicin) +Sorafenib arm and TACE (hydroxycamptothecin + epirubicin) +Sorafenib arm had significant efficacy differences. In conclusion, for patients with advanced HCC, combination therapy with HCPT plus THP/EPI in TACE and Sorfenib may be used as a first-line treatment.

ETS-1 induces Sorafenib-resistance in hepatocellular carcinoma cells via regulating transcription factor activity of PXR.

Transcription factor E26 transformation specific sequence 1 (ETS-1) is a primary regulator in the metastasis of human cancer cells, especially hepatocellular carcinoma (HCC) cells; and it would affect the prognosis of HCC patients who received chemotherapies. However, the regulatory role of ETS-1 in the resistance of HCC cells to molecular-targeting agent remains poorly understood. In the present work, we demonstrate that high ETS-1 expression correlates with poor prognosis of advanced HCC patients received Sorafenib treatment. Mechanistically, ETS-1 binds to nuclear Pregnane X receptor (PXR) directly and enhances PXR's transcription factor activity, which further leads to the induction of the PXR's downstream multi-drug resistance related genes. Overexpression of ETS-1 accelerates the metabolic clearance of Sorafenib in HCC cells and leads to the better survival and faster migration of those cells. The therapeutic studies show that ETS-1 promotes the Sorafenib-resistance of HCC tumor models and ETS-1 blockade enhances the anti-tumor capacity of Sorafenib by decreasing PXR activation. Thus, our study suggests that ETS-1 could enhance the activation of PXR and be a potential therapeutic target for overcoming Sorafenib resistance in HCC treatment.

Machine learning to predict the early recurrence of intrahepatic cholangiocarcinoma: A systematic review and meta­analysis.

The prediction of early recurrent of intrahepatic cholangiocarcinoma (ICC) has been widely investigated; however, the predictive value is currently insufficient. To determine the effectiveness of machine learning (ML) for the diagnosis of early recurrent intrahepatic cholangiocarcinoma (ICC), particularly in comparison with clinical models, the present study aimed to determine which ML model had the best diagnostic performance for inpatients with recurrent ICC. In order to search for studies which could be included, three electronic databases were screened from inception to November 2023. A pairwise meta-analysis was performed to evaluate the diagnostic accuracy of the random effects model. A network meta-analysis was performed to identify the most effective ML-based diagnostic model based on the surface under the cumulative ranking curve score. A total of 5 studies of acceptable quality containing 1,247 patients with ICC were included in the present study. Following pairwise meta-analysis, it was found that the ML-based diagnostic accuracy was greater than that of clinical models (surface under the cumulative ranking curve score closer to 1, with significant differences), which initially proved that the ML-based diagnostic power was more optimal than that of clinical models. According to the network meta-analysis, the nomogram performed the best, indicating that this ML model achieved the best diagnostic accuracy for patients with recurrent ICC. In conclusion, the application of ML-based diagnostic models for patients with recurrent ICC was more optimal than the application of the clinical model. The nomogram model ranked first among the models and is therefore recommended for patients with recurrent ICC.

Which is the best TACE agent for patients with different NLR hepatocellular carcinomas? A systematic review and network meta-analysis.

Background: Transarterial chemoembolization (TACE) is a common treatment for hepatocellular carcinoma (HCC), but the best therapeutic agent for TACE treatment has not been determined. The neutrophil/lymphocyte ratio (NLR) is a systemic immune system marker; however, the ability of the NLR to predict the prognosis of patients with HCC is unknown, and no studies have been conducted to determine the most appropriate TACE regimen for HCC patients with different NLRs. Methods: The PubMed, Embase, Web of Science, and CNKI databases were searched through May 28, 2023. Comparisons of overall survival (OS) among cohort studies with different NLRs and different TACE treatment regimens were performed with a random effects model. Findings: Thirty-five studies involving 9210 patients were included in this meta-analysis. The results showed that Group 3-4 (NLR<2.5) patients had a significantly longer OS than Group 1-2 (NLR 2.5-5.0). Among the patients, Group 1-3 (NLR 2.0-5.0) patients had the best survival after treatment with adriamycin (lnHR (95 % CI = 0.48 [0.31, 0.75] and lnHR (95 % CI = 0.41 [0.19, 0.91]). Among the Group 4 patients (NLR<2.0), the best outcome was obtained with platinum + adriamycin (lnHR (95 % CI = 0.59 [0.45, 0.78]), followed by adriamycin. A subgroup analysis of TACE combined with other treatments showed that adriamycin combined with sorafenib was the most effective and superior to the other treatment agents. Interpretation: The NLR can be used to predict the prognosis of HCC patients treated with TACE; the higher the NLR is, the worse the prognosis. Adriamycin may be the best therapeutic agent for HCC patients treated with TACE.

Is tumor necrosis factor-α monoclonal therapy with proactive therapeutic drug monitoring optimized for inflammatory bowel disease? Network meta-analysis.

BACKGROUND: The efficacy and safety of anti-tumor necrosis factor-α (TNF-α) monoclonal antibody therapy [adalimumab (ADA) and infliximab (IFX)] with therapeutic drug monitoring (TDM), which has been proposed for inflammatory bowel disease (IBD) patients, are still controversial. AIM: To determine the efficacy and safety of anti-TNF-α monoclonal antibody therapy with proactive TDM in patients with IBD and to determine which subtype of IBD patients is most suitable for proactive TDM interventions. METHODS: As of July 2023, we searched for randomized controlled trials (RCTs) and observational studies in PubMed, Embase, and the Cochrane Library to compare anti-TNF-α monoclonal antibody therapy with proactive TDM with therapy with reactive TDM or empiric therapy. Pairwise and network meta-analyses were used to determine the IBD patient subtype that achieved clinical remission and to determine the need for surgery. RESULTS: This systematic review and meta-analysis yielded 13 studies after exclusion, and the baseline indicators were balanced. We found a significant increase in the number of patients who achieved clinical remission in the ADA [odds ratio (OR) = 1.416, 95% confidence interval (CI): 1.196-1.676] and RCT (OR = 1.393, 95%CI: 1.182-1.641) subgroups and a significant decrease in the number of patients who needed surgery in the proactive vs reactive (OR = 0.237, 95%CI: 0.101-0.558) and IFX + ADA (OR = 0.137, 95%CI: 0.032-0.588) subgroups, and the overall risk of adverse events was reduced (OR = 0.579, 95%CI: 0.391-0.858) according to the pairwise meta-analysis. Moreover, the network meta-analysis results suggested that patients with IBD treated with ADA (OR = 1.39, 95%CI: 1.19-1.63) were more likely to undergo TDM, especially in comparison with patients with reactive TDM (OR = 1.38, 95%CI: 1.07-1.77). CONCLUSION: Proactive TDM is more suitable for IBD patients treated with ADA and has obvious advantages over reactive TDM. We recommend proactive TDM in IBD patients who are treated with ADA.

Comparative efficacy and safety of glucagon-like peptide 1 receptor agonists for the treatment of type 2 diabetes: A network meta-analysis.

INTRODUCTION: This study aimed to evaluate the clinical efficacy and safety of 4 weekly formulations of glucagon-like peptide 1 receptor agonists (GLP-1RAs) on glycemic control, including glycemic control, by using a network meta-analysis (NMA). METHODS: PubMed, EMBASE, and Cochrane Library Central Register of Controlled Trials were searched from inception until June 10, 2022. Randomized clinical trials (RCTs) enrolling participants with diabetes mellitus type 2 and a follow-up of at least 12 weeks were included, for which 4 eligible GLP-1RAs Exenatide, Dulaglutide, Semaglutide, Loxenatide were compared with either each other or placebo. The primary outcome is the change of hemoglobin A1c level. Secondary outcomes including additional glycemic control indicators and adverse events (AE). Frequentist random-effect NMA were conducted for effect comparison. This meta-analysis was registered on PROSPERO, CRD42022342241. RESULTS: The NMA synthesized evidence from 12 studies covering 6213 patients and 10 GLP-1RA regimens. A pairwise comparison of glycosylated hemoglobin type A1C (HbA1c) lowering effects showed that once-weekly GLP-1 receptor agonists were significantly better than placebo, and their glucose-lowering intensity was Semaglutide 2.0mg, Semaglutide 1.0mg, Dulaglutide 4.5mg, and Semaglutide 0.5mg, Dulaglutide 3.0mg, PEX168 200ug, Dulaglutide 1.5mg, PEX168 100ug and Dulaglutide 0.75mg. The GLP-1RA regimen has a comparable safety profile for hypoglycemia. And with the exception of PEX168, all other long-acting GLP-1RA drugs had lower rates of diarrhea, nausea and vomiting than placebo. CONCLUSION: Regimens of GLP-1RAs had differential glycemic control. The efficacy and safety of Semaglutide 2.0mg in comprehensively lowering blood sugar showed the best performance.

Efficacy and safety of donepezil for mild cognitive impairment: A systematic review and meta-analysis.

OBJECTIVE: This study intends to systematically evaluate the efficacy and safety of donepezil for improving cognitive function in patients with mild cognitive impairment (MCI), and to provide evidence-based foundation for donepezil in MCI treatment. METHODS: We searched in PubMed, Embase, Cochrane Library, Clinical trials.gov, Web of Science, CQVIP, and CNKI databases, and then we summarized the interventional and observational studies on the use of donepezil for improving the cognitive function of MCI patients. The literature was collected according to the inclusion criteria for data extraction. We evaluated the quality of the selected literature and used Stata 15.0 for meta-analysis. RESULTS: A total of 12 randomized controlled trials (RCTs) and 5 non-randomized concurrent controlled trials (CCTs) were included, and a total of 2847 patients were included. In terms of efficacy, meta-analysis showed that donepezil could significantly improve the MMSE (SMD: 0.85, 95%CI: 0.40-1.31) and MoCA (SMD: 1.88, 95%CI: 0.32-3.45) scores of MCI patients. Donepezil could not significantly reduce ADAS-cog score, nor could it significantly delay disease progression. The quality of the evidence was low overall. In terms of safety, donepezil could significantly increase the risk of adverse reactions such as nausea, vomiting, diarrhea in patients with MCI. CONCLUSION: Donepezil can improve the cognitive function of MCI patients to a certain extent. However, there is no trend of significantly delaying the progression of the disease, and it is easy to lead to the occurrence of adverse reactions.

Systematic review and meta-analysis of calcineurin inhibitors on long-term prognosis of renal transplant patients.

BACKGROUND: Existing guidelines recommend a triple immunosuppressive regimen with calcineurin inhibitors, antimetabolites, and corticosteroids for postoperative immunosuppression in renal transplant patients. However, few studies have compared cyclosporine and tacrolimus for long-term outcomes. In this study, the meta-analysis was used to compare long-term outcomes in renal transplant patients to evaluate the use of cyclosporine vs. tacrolimus. The pros and cons of suppression programs have been analyzed. METHODS: Cyclosporine, tacrolimus, and kidney transplantation, were used as search terms to retrieve relevant publications in PubMed, Embase, and The Cochrane library. Two independent researchers screened and evaluated the relevant results of each search using the RevMan5.4 program to make relevant charts for the meta-analysis. Odds ratios (OR) and 95% confidence intervals (CI) were used to report dichotomous variables, while mean differences (MD) and 95% confidence intervals (CI) were used to report continuous variables. The study took tacrolimus- and cyclosporine-based maintenance immunosuppression as experimental and control groups, respectively. The graft and patient survival outcomes were followed for 5 or more years. RESULTS: Overall, thirteen studies were included in the meta-analysis, including nine randomized controlled trials and four non-randomized controlled trials. Compared with the cyclosporine group, the incidence of rejection, drug conversion, and dyslipidemia were significantly lower in the tacrolimus group. Furthermore, there was higher glomerular filtration rates and graft survival rates in the tacrolimus group than in the cyclosporine group. In contrast, there were no significant differences between the two groups in terms of patient survival, incidence of infection, hypertension and new tumors. However, the use of tacrolimus was associated with a high risk of a new onset of diabetes. CONCLUSION: The meta-analysis showed that, compared with cyclosporine, tacrolimus increases the risk of a new-onset diabetes. However, tacrolimus had higher graft survival rate and better creatinine clearance than cyclosporine.

What Is the Most Suitable Agent Combined With Apatinib for Transarterial Chemoembolization Treatment in Advanced Hepatocellular Carcinoma Patients? A Systematic Review and Network Meta-analysis.

Purpose: Combined therapy with transarterial chemoembolization (TACE) and apatinib is superior in therapeutic effect compared with TACE alone in patients with hepatocellular carcinoma (HCC). To determine the most suitable agent combined with apatinib for TACE treatment, we did a systematic review and network meta-analysis. Methods: Four electronic databases were searched from inception until November 2021. Randomized controlled trials (RCTs) and retrospective studies that combined therapy of TACE and apatinib (TACE+A) compared with TACE alone were included. We performed random-effect pairwise and network meta-analyses to summarize the outcomes about efficacy and safety. Results: Forty-five original studies including 3,876 patients were included. In terms of efficacy, we evaluated treatment response, 6 months overall survival (OS), 1 year OS, 6 months progression-free survival (PFS), 1 year PFS, alphafetoprotein (AFP), matrix metalloproteinase 9 (MMP9), and vascular endothelial growth factor (VEGF). Significant differences always appear in TACE agent subgroups of adriamycin, platinum, and fluorouracil from both pairwise and network meta-analysis, while significant differences could also be found in apatinib dosage of 500 and >500 mg/day subgroups and in both RCT and retrospective study subgroups. From second time network analysis, compared with TACE alone, subgroups with TACE agents of oxaliplatin, cisplatin, pirarubicin, epirubicin, and 5-fluorouracil ranked front. In addition, the safety of adriamycin, platinum, and fluorouracil subgroups is acceptable. Conclusions: In conclusion, the most suitable agents in TACE combined with apatinib were adriamycin+platinum ± fluorouracil combination therapy. Systematic Review Registration: The study was registered with https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=311650, PROSPERO, CRD4202022311650.

Diagnostic accuracy and prognostic significance of Glypican-3 in hepatocellular carcinoma: A systematic review and meta-analysis.

Purpose: Glypican-3 (GPC-3) expression is abnormal in the occurrence and development of hepatocellular carcinoma (HCC). To explore whether GPC-3 has diagnostic accuracy and prognostic significance of HCC, we did a systematic review and meta-analysis. Method: PubMed, Embase, Cochrane Library, and China National Knowledge Infrastructure were searched with keywords "GPC-3" and "HCC" and their MeSH terms from inception to July 2022. We applied the hierarchical summary receiver operating characteristic model and evaluated the diagnostic value of GPC-3 alone and combination, and the correlation between high and low GPC-3 expression on clinicopathological features and survival data in prognosis. Results: Forty-one original publications with 6,305 participants were included, with 25 of them providing data for diagnostic value and 18 records were eligible for providing prognostic value of GPC-3. GPC-3 alone got good diagnostic value in patients with HCC when compared with healthy control and moderate diagnostic value when compared with patients with cirrhosis. In addition, combination of GPC-3 + AFP and GPC-3 + GP73 got great diagnostic value in HCC versus cirrhosis groups; the combination of GPC-3 can also improve the diagnostic accuracy of biomarkers. Moreover, we discovered that overexpression of GPC-3 was more likely found in HBV infection, late tumor stage, and microvascular invasion groups and causes shorter overall survival and disease free survival, which means poor prognosis. Conclusion: GCP-3 could be used as a biomarker in HCC diagnosis and prognosis, especially in evaluated diagnostic value in combination with AFP or GP73, and in forecasting worse survival data of overexpression GPC-3.

miR-140-3p enhances the sensitivity of LUAD cells to antitumor agents by targeting the ADAM10/Notch pathway.

Background: The Notch pathway, which is related to the drug-resistance of lung adenocarcinoma (LUAD) type of non-small cell lung cancer (NSCLC) cells, is activated by cleavage of Notch proteins mediated by ADAMs, ADAM10 or ADAM17. Methods: In the present study, our results demonstrated that of these two ADAMs, the expression of ADAM10 in clinical samples of the LUAD type of NSCLC was much higher than that of ADAM17, while miR-140-3p - an miRNA that could target ADAM10 - was identified by an online tool: miRDB (miRNA database). The detail function and mechanism of miR-140-3p in regulating the sensitivity of NSCLC cells to antitumor drugs was systematically explored in vitro and in vivo. Results: In A549, a typical NSCLC LUAD cell line, miR-140-3p decreased ADAM10 expression and repressed activation of the Notch pathway by repressing cleavage of Notch proteins. The expression of miR-140-3p was negatively related to ADAM10 in clinical specimens. Nucleocytoplasmic separation/subfraction assays showed that miR-140-3p was able to inhibit the cleavage of Notch protein, and led to the accumulation of Notch intracellular domains (NICD) in the nucleus. Overexpression of miR-140-3p enhanced the sensitivity of A549 cells to antitumor agents by targeting the 3'UTR region of ADAM10 mRNA in both cultured cells and in vivo models. Conclusion: ADAM10 plays a major role in LUAD, and miR-140-3p acts on ADAM10 and inhibits its expression and the cleavage of Notch protein, leading to the inhibition the activity of the Notch pathway, and ultimately upregulating LUAD cell sensitivity to anti- tumor drugs.
