RESUMO

The capability to gather heterogeneous data, alongside the increasing power of artificial intelligence to examine it, leading a revolution in harnessing multimodal data in the life sciences. However, most approaches are limited to unimodal data, leaving integrated approaches across modalities relatively underdeveloped in computational pathology. Pathogenomics, as an invasive method to integrate advanced molecular diagnostics from genomic data, morphological information from histopathological imaging, and codified clinical data enable the discovery of new multimodal cancer biomarkers to propel the field of precision oncology in the coming decade. In this perspective, we offer our opinions on synthesizing complementary modalities of data with emerging multimodal artificial intelligence methods in pathogenomics. It includes correlation between the pathological and genomic profile of cancer, fusion of histology, and genomics profile of cancer. We also present challenges, opportunities, and avenues for future work.

RESUMO

Layered VS2 has been widely used as a battery anode material owing to its large specific surface area and controllable ion-transport channel. However, its semiconductor properties and poor cycling stability seriously limit its further applications. Herein, a two-dimensional BN/VS2 heterostructure (BVH) was constructed as an anode material for rechargeable metal-ion batteries (RMIBs). Demonstrated using first principles calculations, BVH exhibits a metallic property due to lattice stress between monolayer BN and VS2. BVH displays low ion diffusion energy barriers (0.13, 0.43, and 0.56 eV) and high theoretical capacities (447, 553.5, and 340.7 mA h g-1) for Li+, Na+, and Mg2+ storage. In BVH, the VS2 layer as the main redox center supports charge transfer, while the inactive BN layer enables high structural stability. This synergistic effect is expected to simultaneously achieve a high rate, high capacity, and long life. This design provides an important insight into developing new anode materials for RMIBs.

RESUMO

BACKGROUND: Heart failure (HF), a common cardiovascular condition, is characterized by significant morbidity and mortality. While traditional Chinese medicine (TCM) is often used as a complementary approach in HF management, systematic evaluations of its impact on clinical outcomes, TCM syndrome scores, and B-type natriuretic peptide (BNP) levels are lacking. This study fills this gap through a comprehensive analysis of randomized controlled trials (RCTs) focusing on TCM for HF treatment. It encompasses an assessment of methodological quality, a meta-analysis, and an evaluation of evidence quality based on established standards. The results offer crucial insights into the potential advantages and constraints of TCM in HF management. AIM: To systematically analyze the effects of TCM on the clinical comprehensive outcomes, TCM syndrome scores, and BNP levels in patients with HF and evaluated the quality of evidence for these trials. METHODS: RCTs on TCM for HF treatment published since the establishment of the database were searched in four Chinese and English databases, including China National Knowledge Infrastructure, Wanfang, VIP Information Chinese Science and Technology Journal, and PubMed. Methodological quality was assessed for the included studies with the Cochrane risk-of-bias assessment tool, and the meta-analysis and publication bias assessment was performed with the RevMan5.3 software. Finally, the quality of evidence was rated according to the GRADE criteria. RESULTS: A total of 1098 RCTs were initially retrieved. After screening, 16 RCTs were finally included in our study, which were published between 2020 and 2023. These RCTs involved 1660 HF patients, including 832 in the TCM group [TCM combined with conventional Western medicine (CMW) treatment] and 828 in the CWM group (CWM treatment). The course of treatments varied from 1 wk to 3 months. TCM syndrome differentiation was analyzed in 11 of the included RCTs. In all included RCTs, outcome indicators included comprehensive clinical outcomes, TCM syndrome scores, and BNP levels. The meta-analysis results showed significant differences between the TCM and CWM groups in terms of comprehensive clinical outcomes [risk ratio = -0.54; 95% confidence interval (CI) = -0.61, -0.47; P < 0.00001], TCM syndrome scores [weighted mean difference (WMD) = -142.07; 95%CI = -147.56, -136.57; P < 0.00001], and BNP levels (WMD = -142.07; 95%CI = -147.56, -136.57; P < 0.00001). According to the GRADE criteria, RCTs where "TCM improves clinical comprehensive outcomes" were rated as low-quality evidence, and RCTs where "TCM reduces TCM syndrome scores" or "TCM decreases BNP levels" were rated as medium-quality evidence. CONCLUSION: TCM combined with CWM treatment effectively improves comprehensive clinical outcomes and diminishes TCM syndrome scores and BNP levels in HF patients. Given the low and medium quality of the included RCTs, the application of these results should be cautious.

RESUMO

Rechargeable magnesium batteries (RMBs) are considered as highly promising energy storage systems. However, the lack of cathode materials with fast Mg2+ diffusion kinetics and high energy density severely hinders the development of RMBs. Herein, a two-dimensional (2D) VO2/VS2 heterostructure as a RMB cathode material is proposed by introducing an O-V-O layer in VS2 to improve the discharge voltage and specific capacity while keeping the fast Mg2+ diffusion kinetics. Based on first principle calculations, the geometric structures, electronic characteristics of the VO2/VS2 heterostructure, and the adsorption properties and diffusion behaviors of Mg2+ in VO2/VS2 are systematically studied. The metallic properties of VO2/VS2 and a relatively low diffusion barrier of Mg2+ (0.6 eV) in VO2/VS2 enable a large potential in delivering high rate performance in actual RMBs. Compared with traditional VS2 materials (1.25 V), the average discharge platform of VO2/VS2 could be increased to 1.7 V. The theoretical capacities of the layered VS2 and VO2/VS2 are calculated as 233 and 301 mA h g-1, respectively. Thus, the VO2/VS2 heterostructure exhibits a high theoretical energy density of 511.7 W h kg-1, significantly surpassing that of VS2 (291.3 W h kg-1). This work provides important guidance for designing high-energy and high-rate 2D heterostructure cathode materials for RMBs and other multivalent ion batteries.

RESUMO

In 2021, breast cancer accounted for a substantial proportion of cancer cases and represented the second leading cause of cancer deaths among women worldwide. Although tumor cells originate from normal cells in the human body, they possess distinct biological characteristics resulting from changes in gene structure and function of cancer cells in contrast with normal cells. These distinguishing features, known as hallmarks of cancer cells, differ from those of normal cells. The hallmarks primarily include high metabolic activity, mitochondrial dysfunction, and resistance to cell death. Current evidence suggests that the fundamental hallmarks of tumor cells affect the tissue structure, function, and metabolism of tumor cells and their internal and external environment. Therefore, these fundamental hallmarks of tumor cells enable tumor cells to proliferate, invade and avoid apoptosis. Modifying these hallmarks of tumor cells represents a new and potentially promising approach to tumor treatment. The key to breast cancer treatment lies in identifying the optimal therapeutic agent with minimal toxicity to normal cells, considering the specific types of tumor cells in patients. Some herbal medicines contain active ingredients which can precisely achieve this purpose. In this review, we introduce Ginsenoside's mechanism and research significance in achieving the therapeutic effect of breast cancer by changing the functional hallmarks of tumor cells, providing a new perspective for the potential application of Ginsenoside as a therapeutic drug for breast cancer.

RESUMO

PURPOSE: Triple-negative breast cancer (TNBC) is a highly heterogeneous and aggressive breast malignancy. Glucocorticoid (GC)-glucocorticoid receptor (GR) pathway plays a pivotal role in the cellular responses to various stresses including chemotherapy. Serum- and glucocorticoid-induced kinase-1 (SGK1) is known as an important downstream effector molecule in the GR signaling pathway, we attempted to explore its clinicopathological and functional significance in TNBC in which GR is expressed. METHODS: We first immunolocalized GR and SGK1 and correlated the results with clinicopathological variables and clinical outcome in 131 TNBC patients. We also evaluated the effects of SGK1 on the cell proliferation and migration in TNBC cell lines with administration of dexamethasone (DEX) to further clarify the significance of SGK1. RESULTS: The status of SGK1 in carcinoma cells was significantly associated with adverse clinical outcome in TNBC patients examined and was significantly associated with lymph node metastasis, pathological stage, and lymphatic invasion of the patients. In particular, SGK1 immunoreactivity was significantly associated with an increased risk of recurrence in GR-positive TNBC patients. Subsequent in vitro studies also demonstrated that DEX promoted TNBC cell migration and the silencing of gene expression did inhibit the cell proliferation and migration of TNBC cells under DEX treatment. CONCLUSIONS: To the best of our knowledge, this is the first study to explore an association between SGK1 and clinicopathological variables and clinical outcome of TNBC patients. SGK1 status was significantly positively correlated with adverse clinical outcome of TNBC patients and promoted carcinoma cell proliferation and migration of carcinoma cells.

RESUMO

OBJECTIVES: This study aimed to comprehensively investigate the potential active components and therapeutic mechanisms of Shen-Kui-Tong-Mai granule (SKTMG) in the treatment of heart failure. METHODS: Network pharmacology combined with ultra-high performance liquid chromatography coupled with tandem mass spectrometry (UHPLC-MS/MS), molecular docking, and in vivo validation was performed to identify the active components and the potential targets for SKTMG to improve chronic heart failure (CHF). KEY FINDINGS: The network pharmacology identified 192 active compounds and 307 potential consensus targets for SKTMG. On the other hand, network analysis discovered 10 core target genes related to the MAPK signal pathway. These genes include AKT1, STAT3, MAPK1, P53, SRC, JUN, TNF, APP, MAPK8 and IL6. The molecular docking results revealed that the SKTMG components were luteolin, quercetin, astragaloside IV and kaempferol, which could bind AKT1, MAPK1, P53, JUN, TNF and MAPK8. Additionally, SKTMG inhibited phosphorylation of AKT, P38, P53 and c-JUN, and reduced TNF-α expression in CHF rats. CONCLUSIONS: The present results demonstrated that network pharmacology combined with UHPLC-MS/MS, molecular docking and in vivo validation can facilitate the identification of active components and the potential targets for SKTMG to improve CHF.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Qian Yang Yu Yin granules (QYYYG) have a long history in the treatment of hypertensive renal damage (HRD) in China. Clinical studies have found that QYYYG stabilizes blood pressure and prevents early renal damage. However, the exact mechanism is not entirely clear. AIM OF THE STUDY: To evaluate the therapeutic effect and further explore the therapeutic mechanism of QYYYG against HRD. MATERIALS AND METHODS: The efficacy of QYYYG in treating HRD was assessed in spontaneous hypertension rats (SHR). Renal autophagy and the TRPC6-CaMKKß-AMPK pathway in rats were evaluated. The regulatory role of QYYYG in angiotensin II (Ang II) induced abnormal autophagy in rat podocytes was determined by detecting autophagy-related proteins, intracellular Ca2+ content, and the TRPC6-CaMKKß-AMPK-mTOR pathway expressions. Finally, we established a stable rat podocyte cell line overexpressing TRPC6 and used the cells to verify the regulatory effects of QYYYG. RESULTS: QYYYG alleviated HRD and reversed the abnormal expression of autophagy-related genes in the SHR. In vitro, QYYYG protected against Ang II-induced podocyte damage. Furthermore, treatment of podocytes with QYYYG reversed Ang II-induced autophagy and inhibited Ang II-stimulated TRPC6 activation, Ca2+ influx and activation CaMKKß-AMPK pathway. Overexpression of TRPC6 resulted in pronounced activation of CaMKKß, AMPK, and autophagy induction in rat podocytes, which were significantly attenuated by QYYYG. CONCLUSIONS: The present study suggested that QYYYG may exert its HRD protective effects in part by regulating the abnormal autophagy of podocytes through the TRPC6-CaMKKß-AMPK-mTOR pathway.

RESUMO

Background: The aim of the study was to establish and validate a novel prognostic nomogram of cancer-specific survival (CSS) in resected hilar cholangiocarcinoma (HCCA) patients. Methods: A training cohort of 536 patients and an internal validation cohort of 270 patients were included in this study. The demographic and clinicopathological variables were extracted from the Surveillance, Epidemiology and End Results (SEER) database. Univariate and multivariate Cox regression analysis were performed in the training cohort, followed by the construction of nomogram for CSS. The performance of the nomogram was assessed by concordance index (C-index) and calibration plots and compared with the American Joint Committee on Cancer (AJCC) staging systems. Decision curve analysis (DCA) was applied to measure the predictive power and clinical value of the nomogram. Results: The nomogram incorporating age, tumor size, tumor grade, lymph node ratio (LNR) and T stage parameters was with a C-index of 0.655 in the training cohort, 0.626 in the validation cohort, compared with corresponding 0.631, 0.626 for the AJCC 8th staging system. The calibration curves exhibited excellent agreement between CSS probabilities predicted by nomogram and actual observation in the training cohort and validation cohort. DCA indicated that this nomogram generated substantial clinical value. Conclusions: The proposed nomogram provided a more accurate prognostic prediction of CSS for individual patients with resected HCCA than the AJCC 8th staging system, which might be served as an effective tool to stratify resected HCCA patients with high risk and facilitate optimizing therapeutic benefit.

RESUMO

BACKGROUND: Metastasis and endocrine therapy resistance are clinical challenges in the treatment of estrogen receptor (ER) -positive breast tumors. Therefore, mechanistic exploration of tamoxifen (TAM) resistance is considered pivotal to improve the prognosis of ER positive breast cancer patients. We previously demonstrated the correlation between FE65 and ER, and subsequently explored the effects of FE65 on TAM and potential interaction between FE65 and Osteopontin (OPN) in ER-positive breast cancer. METHODS: We immunolocalized FE65 and OPN in ER-positive breast cancers and correlated the results with their clinicopathological variables. We then performed proximity ligation and proliferation assays to correlate TAM resistance with FE65 expression. The RT2 Profiler Human PCR Array Human Estrogen Receptor Signaling was also used to profile 96 ER related genes. Hoechst 33342 Staining was used to evaluate apoptosis. RESULTS: FE65 immunoreactivity was significantly associated with higher pathological N factor of the cases examined, and a potential correlation with tamoxifen resistance of the ER-positive patients. FE65 knockdown significantly increased the proportion of apoptotic carcinoma cells. The statistically significant positive correlation between FE65 and OPN was detected in this study. Subsequent immunohistochemical analyses revealed that OPN status was significantly associated with cancer metastasis and overall survival of 142 patients and FE65 status. CONCLUSIONS: We firstly demonstrated the clinicopathological significance of FE65 in ER-positive breast cancer patients and results indicated that the effects of FE65 on ER-positive breast cancer patients were mediated through OPN expression. In addition, results suggested the clinical value of FE65 as potential prognostic factor and surrogate marker of TAM therapy in ER-positive breast cancer patients.

RESUMO

BACKGROUND: Transcription coregulator adapter protein FE65 is well known to play pivotal roles in pathogenesis of Alzheimer's disease by regulating amyloid precursor protein (APP) expression and processing. APP was recently reported to be also involved in development of human malignancies. Therefore, in this study, we studied FE65 status in different subtypes of human breast cancer and correlated the results with cell proliferation and migration of carcinoma cells and clinicopathological features of breast cancer patients to explore its biological and clinical significance in breast cancer. METHODS: We first immunolocalized FE65 and APP in 138 breast cancer patients and correlated the results with their tumor grade. Then, we did further exploration by proximity ligation assay, WST-8, and wound-healing assay. RESULTS: FE65 immunoreactivity in carcinoma cells was significantly associated with lymph-node metastasis, ERα, and high pathological N factor. APP immunoreactivity was significantly positively correlated with high pathological N factor. FE65, APP, and p-APP were all significantly correlated with shorter disease-free survival of breast cancer patients. In addition, the status of FE65 was significantly associated with overall survival. Results of in vitro analysis revealed that FE65 promoted the migration and proliferation of T-47D and ZR-75-1 breast carcinoma cells. In situ proximity ligation assay revealed that FE65 could bind to APP in the cytoplasm. FE65 was also associated with APP and ERα in carcinoma cells, suggesting their cooperativity in promoting carcinoma cell proliferation and migration. APP was also significantly associated with adverse clinical outcome of the patients. CONCLUSIONS: This is the first study to explore the clinical significance of FE65 in human breast cancer. The significant positive correlation of FE65 with poor clinical outcome, direct binding to APP, and promotion of carcinoma cell proliferation and migration indicated that FE65-APP pathway could serve as the potential candidate of therapeutic intervention in breast cancer patients.

RESUMO

Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide. SET and MYND domain-containing protein 3 (SMYD3) has been shown to promote the progression of various types of human cancers, including liver cancer; however, the detailed molecular mechanism is still largely unknown. Here, we report that SMYD3 expression in HCC is an independent prognostic factor for survival and promotes the proliferation and migration of HCC cells. We observed that SMYD3 upregulated sphingosine-1-phosphate receptor 1 (S1PR1) promoter activity by methylating histone 3 (H3K4me3). S1PR1 was expressed at high levels in HCC samples, and high S1PR1 expression was associated with shorter survival. S1PR1 expression was also positively correlated with SMYD3 expression in HCC samples. We confirmed that SMYD3 promotes HCC cell growth and migration in vitro and in vivo by upregulating S1PR1 expression. Further investigations revealed that SMYD3 affects critical signaling pathways associated with the progression of HCC through S1PR1. These findings strongly suggest that SMYD3 has a crucial function in HCC progression that is partially mediated by histone methylation at the downstream gene S1PR1, which affects key signaling pathways associated with carcinogenesis and the progression of HCC.

RESUMO

BACKGROUND: In recent years, the incidence rate of hypertensive nephropathy has been increasing quickly, which has been a major threat to people's health. Renin-angiotensin-aldosterone system blockers have certain curative effects. However, there are some patients having serious adverse reactions, and the benefit population is limited, so the treatment of hypertensive renal damage is necessary to have beneficial supplement. More and more clinical studies have shown that ginkgo leaf extract and dipyridamole injection (GDI) combined with antihypertensive drugs has achieved good results in the treatment of hypertensive renal damage. It is supposed to be a supplementary treatment in hypertensive nephropathy. OBJECTIVES: To systematically assess the efficacy and safety of GDI combined with antihypertensive drugs on hypertensive renal injury. METHODS: Seven databases including PubMed, Cochrane Library, Embase, Wanfang database, China biomedical literature service system (Sino Med), VIP Chinese Sci-tech journal database (VIP), and China national knowledge internet (CNKI) were retrieved to collect randomized controlled trials (RCTs) in the experimental group containing combined therapy of hypertensive nephropathy with GDI and antihypertensive drugs. The retrieval time was from the establishment of database to July 8, 2020. Two researchers independently selected literature, extracted data, and evaluated the risk of bias in the study. The methodological quality was evaluated with Cochrane handbook and meta-analysis was performed with Stata 14.0 software. RESULTS: Eight studies were included in this study which involved 556 patients. The meta-analyses indicated that, compared with using antihypertensive drugs alone, combined treatment of GDI with antihypertensive drugs can decrease 24-hour urinary total protein (weighted mean difference [WMD] -0.61, 95% confidence interval [CI]: -0.82, -0.39; k = 6, P ≤ .001), blood urea nitrogen (WMD -1.27, 95% CI: -2.45, -0.10; k = 6, P = .033, serum creatinine (WMD -29.50, 95% CI: -56.44, -2.56; number of estimates [k] = 6, P = .032). CONCLUSIONS: Our meta-analyses showed that GDI combined with antihypertensive drugs can improve the renal function of hypertensive patients with renal injury.

RESUMO

AIMS: The association of strictly defined metabolic healthy obese (MHO) with subclinical cardiac function was unclear. Our study aims to examine the role of MHO in subclinical cardiac dysfunction in a Chinese population. METHODS AND RESULTS: The study subjects were recruited from Danyang from 2017 to 2019. Obesity was defined by body mass index (BMI) categories (normal weight, overweight and obesity). Metabolic health was strictly defined as having neither any of the guidelines recommended metabolic syndrome components nor insulin resistance. Thus, subjects were grouped by BMI categories and metabolic health status as six groups. Preclinical systolic (global longitudinal strain [GLS]) and diastolic function were assessed by 2D speckle tracking, and transmitral and tissue Doppler imaging, respectively. The 2757 participants (mean age ± standard deviation, 52.7 ± 11.7 years) included 1613 (58.5%) women, 999 (36.2%) obese, 2080 (75.4%) metabolically unhealthy and 93 (3.4%) MHO participants. After adjustment for covariates, the trend was similar for left ventricular (LV) ejection fraction (Ptrend  ≥ 0.07) but significantly worse for GLS, e' and E/e' (Ptrend  ≤ 0.02) across the six groups or passing from normal weight to obese individuals irrespective of metabolic status. MHO participants had lower GLS (20.4 vs. 21.4%) and e' (9.6 vs. 10.6 cm/s) compared with controls (P < 0.0001) but had similar GLS (P = 0.47) compared with metabolically unhealthy obese (MUO). Regardless of obesity status, metabolically unhealthy participants had worse diastolic function compared with their metabolically healthy counterparts (P ≤ 0.0004). Compared with controls, MHO individuals were at higher risk of subclinical LV systolic dysfunction (OR = 3.44, 95% CI = 1.25-9.49, P = 0.02). These results were robust to sensitivity analysis. CONCLUSIONS: MHO was substantially associated with worse subclinical systolic function although early diastolic dysfunction seemed to be more accentuated in MUO.

RESUMO

Iron oxide nanomaterials with mimic enzymes activity have been paid more attention in the clinical diagnosis field. The modified surface molecules would influence the catalytic activity of nanozyme, which is worth studying. Furthermore, the traditional detection strategy is based on colorimetric change of substrates, however, the optical signal is easy to be interfered in complex biological applications. In our research, an efficient and facile preparation strategy was developed to obtain functional artificial nanozymes. Herein, three kinds of surfactants, including citrate acid, poly(ethylene glycol) bis (carboxymethyl) ether and tannic acid have been applied to modify these nanomaterials that showed uniform size, high soluble dispersity and stability. Furthermore, these nanozymes exhibited different peroxidase-like activity to catalyze the hydrogen peroxide and 3,3',5,5'-tetramethylbenzidine. More importantly, magnetic relaxation effect of iron oxide nanozymes was found to be changed during the catalytic reaction. In addition, the relationship between the magnetic signal of nanozymes and the substrate concentration showed a good linear dependence. Combined with the natural enzymes, the magnetic detection of iron oxide nanozymes also exhibited excellent substrate specificity. On these bases, a dual-function specific assay was constructed and further used for glucose detection. In conclusion, this study demonstrated an efficient iron oxide nanozymes preparation method and constructed a new synergistically colorimetric-magnetic diagnosis strategy.

RESUMO

BACKGROUND: Paradoxical embolism (PDE) presented with concomitant pulmonary embolism (PE) and renal artery embolism (RAE) which occurred to breast cancer patient after breast-conserving therapy, has never been reported. CASE PRESENTATION: A 55-year-old female with breast cancer exhibited unexplained hypoxemia, followed with vomiting, diarrhea, unilateral flank pain and abdominal pain after lumpectomy 12 h. The urgent multi-detector row computed tomography (MDCT) confirmed the diagnosis of PE and RAE. Confusingly, the patient had no history of intracardiac defect, cardiac valvular diseases, atrial fibrillation or other cardiovascular disease and the definite cause was still unclear. However, after 10 days of prompt anticoagulant therapy in ICU, she was discharged in good condition. CONCLUSION: Breast cancer patients after surgery suffering from unexplained hypoxemia, abdominal pain, vomiting and diarrhea should be highly suspicious of PE or RAE, even PDE. Any clinical presentation on these postoperative patients should be given much more attention to make accurate diagnosis and appropriate interventions.

RESUMO

Triple-negative breast cancer shows resistance to conventional radiotherapies and chemotherapies, and few molecular targeted therapies are currently available for this malignancy in clinical settings. In this work, a theranostic nanosystem with a core-shell structure was synthesized through self-assembly of amphiphilic macromolecules, which can be used in effective catalysis therapy and phototherapy. Herein, we report that superparamagnetic iron oxide nanocrystals and IR780 dye were effectively loaded into the hydrophobic core of the nanosystem, which enabled dual-modality magnetic resonance imaging and near-infrared fluorescence imaging. Furthermore, on the hydrophilic crown, the neighboring carboxylic acid-based amide linkage showed charge conversion properties in the tumor acidic microenvironment and endowed the system with targeted diagnosis and delivery. Upon light excitation, this theranostic system exerted synergistic anti-cancer activity through the nano-enzyme catalysis effect enhanced phototherapy in a triple-negative 4T1 breast cancer model. Furthermore, there were no obvious side-effects. The results of our study demonstrate the great potential of this theranostic nanosystem in cancer diagnosis and therapy.

RESUMO

Background: Sodium tanshinone IIA sulfonate (STS) injection, the extractive of traditional Chinese medicine Danshen, is supposed to be a supplementary treatment in hypertensive nephropathy. Objectives: To evaluate the efficacy and safety of STS in treatment of hypertensive nephropathy. Methods: We systematically searched China National Knowledge Infrastructure (CNKI), Chinese Scientific Journals Database (VIP), Wan-fang database, Chinese Biomedicine Database (CBM), PubMed, Embase, Web of Science, and Cochrane Library from their inception to December 2018. All studies were screened by two reviewers according to the inclusion and exclusion criteria independently. The Cochrane Collaboration's risk tool was used to assess the methodological quality of the included studies. Reviewer Manager 5.3 was employed for statistical analysis. Results: Sixteen trials involving 1,696 patients were included. The meta-analysis results indicated a combination of STS and angiotensin receptor blockers (ARBs) was more effective than ARB monotherapy in modulating hypertensive nephropathy, as represented by improved estimated glomerular filtration rate (eGFR) [mean difference (MD) = 6.87, 95% CI (4.47, 9.28), P < 0.00001] and reduced 24 h urinary protein [MD = -0.23, 95% CI (-0.27, -0.19), P < 0.00001], serum creatinine (SCr) [MD = -21.74, 95% CI (-24.11, -19.38), P < 0.00001], cystatin-C [MD = -0.16, 95% CI (-0.24, -0.07), P = 0.0003], urinary immunoglobulin G (IgG) [MD = -0.85, 95% CI (-1.11, -0.59), P < 0.00001], and urinary transferrin [MD = -0.61, 95% CI (-1.04, -0.17), P = 0.007]. In addition, the combination therapy had better control in systolic blood pressure (SBP) [MD = -6.53, 95% CI (-8.19, -4.87), P < 0.00001] and diastolic blood pressure (DBP) [MD = -4.14, 95% CI (-5.69, -2.59), P < 0.00001]. Only three trials reported adverse events, and no adverse drug reactions were observed. Conclusions: STS combined with ARBs had a stronger effect on improving renal function in patients with primary hypertensive nephropathy than ARB monotherapy. The combination therapy also provided auxiliary hypotensive effects. Further large-scale, multicenter, and rigorously designed randomized controlled trials (RCTs) should be conducted to confirm our findings.
