- Abstract
In this study, a specifically-designed aggregation-induced emission fluorogen (AIEgen) with nanoparticle aggregates was used to quantitatively evaluate the bioaccumulation of Hg2+and visualize Hg2+kinetics in vivowithin the rotifer Brachionus plicatilisfor the first time. Quantitative results showed that a sharp drop in Hg2+concentration occurred at the very beginning in the medium containing rotifers and Hg2+, showing a quick initial uptake of Hg2+by the rotifers, and then the concentration in the medium plateaued after 5 min. With an increase in rotifer density, the amount of bioaccumulation increased in the rotifer. However, the bioaccumulation efficiency of Hg2+decreased from 5.28 μg mg−1h−1at a low rotifer density of 0.093 mg ml−1to 2.61 μg mg−1h−1at a high rotifer density of 0.375 mg mL−1. Moreover, the fluorescence images and spectra results illustrate that the ingestion of Hg2+by the rotifer was viaits mouth surrounded by the ciliary corona to the digestive tract, and Hg2+could not permeate into the body integument through diffusion during the study period. Hg2+-induced fluorescence in rotifers dissipated in 6 h after staining, possibly through defecation and excretion. This study indicates that inorganic mercury can be quickly ingested by a rotifer viafeeding, but is unlikely deposited as methylated mercury in rotifer tissues.

Helicobacter pylori, a Gram-negative, microaerophilic bacterium found in the stomach, is assumed to be associated with carcinogenesis, invasion and metastasis in digestive diseases. Cytotoxin-associated gene A (CagA) is an oncogenic protein of H. pylori that is encoded by a Cag pathogenicity island related to the development of gastric cancer. The epithelial–mesenchymal transition (EMT) is the main biological event in invasion or metastasis of epithelial cells. H. pylori may promote EMT in human gastric cancer cell lines, but the specific mechanisms are still obscure. We explored the underlying molecular mechanism of EMT induced by H. pylori CagA in gastric cancer. In our article, we detected gastric cancer specimens and adjacent non-cancerous specimens by immunohistochemistry and found increased expression of the EMT-related regulatory protein TWIST1 and the mesenchymal marker vimentin in cancer tissues, while programmed cell death factor 4 (PDCD4) and the epithelial marker E-cadherin expression decreased in cancer specimens. These changes were associated with degree of tissue malignancy. In addition, PDCD4 and TWIST1 levels were related. In gastric cancer cells cocultured with CagA expression plasmid, CagA activated TWIST1 and vimentin expression, and inhibited E-cadherin expression by downregulating PDCD4. CagA also promoted mobility of gastric cancer cells by regulating PDCD4. Thus, H. pylori CagA induced EMT in gastric cancer cells, which reveals a new signaling pathway of EMT in gastric cancer cell lines. [ABSTRACT FROM AUTHOR]

Helicobacter pylori-infected gastric mucosa is characterized by high levels of interferon-γ (IFN-γ), but whether the high level of IFN-γ regulates the virulence of H. pylori is unclear. Here, we characterized the response of H. pylori to IFN-γ and found by indirect immunofluorescence that IFN-γ can bind to H. pylori. The binding resulted in the altered expression of 14 proteins, including the virulence factor, cytotoxin-associated gene A (CagA), whose expression was downregulated. The transcription and translation of CagA downregulated by IFN-γ was further confirmed by reverse transcriptase-PCR and Western blot analysis. We co-cultured the human gastric cancer cell line AGS with H. pylori exposed to IFN-γ; both phosphorylated CagA and nonphosphorylated CagA in AGS cells were downregulated by IFN-γ, and the proportion of cells with the 'hummingbird' phenotype was also decreased. Thus, IFN-γ can help control H. pylori infection indirectly through the virulence factor CagA. [ABSTRACT FROM AUTHOR]

- Abstract
ABSTRACTThe increase in drug resistance and invasion caused by biofilm formation brings enormous challenges to the management of Candidainfection. Aspirin's antibiofilm activity in vitrowas discovered recently. The spectrophotometric method and the XTT {2,3-bis(2-methoxy-4-nitro-5-sulfophenyl)-5-[(phenylamino)carbonyl]-2H-tetrazolium hydroxide} reduction assay used for data generation make it possible to evaluate fungal biofilm growth accurately. The combined use of the most commonly used methods, the fractional inhibitory concentration index (FICI) and a newly developed method, the ΔEmodel, which uses the concentration-effect relationship over the whole concentration range instead of using the MIC index alone, makes the interpretation of results more reliable. As an attractive tool for studying the pharmacodynamics of antimicrobial agents, time-kill curves can provide detailed information about antimicrobial efficacy as a function of both time and concentration. In the present study, in vitrointeractions between aspirin (acetylsalicylic acid [ASA]) and amphotericin B (AMB) against planktonic cells and biofilm cells of Candida albicansand C. parapsilosiswere evaluated by the checkerboard microdilution method and the time-kill test. Synergistic and indifferent effects were found for the combination of ASA and AMB against planktonic cells, while strong synergy was found against biofilm cells analyzed by FICI. The ΔEmodel gave more consistent results with FICI. The positive interactions in concentration were also confirmed by the time-kill test. Moreover, this approach also revealed the pharmacodynamics changes of ASA and synergistic action on time. Our findings suggest a potential clinical use for combination therapy with ASA and AMB to augment activity against biofilm-associated infections.

- Abstract
Nano-sized calcium carbonate (CaCO3) was used to reinforce a semi-crystalline ethylene-propylene-diene monomer rubber (EPDM). For comparison, micron-sized CaCO3was also studied. It was found that both nano-sized CaCO3and micron-sized CaCO3improved the mechanical properties of the EPDM vulcanizates, and nano-sized CaCO3exhibited better reinforcement effect than micron-sized CaCO3. The difference in reinforcement effects of nano-sized CaCO3and micron-sized CaCO3was explained in terms of the filler particle size and the crosslink density of the vulcanizates. The nano-sized CaCO3was also modified by titanate, borate, and aluminate-titanate complex coupling agents and used to reinforce EPDM vulcanizates. The results showed that titanate coupling agent coated nano-sized CaCO3exhibited the best reinforcement ability. FE-SEM micrographs showed that stearic acid, titanate, and aluminate-titanate complex coupling agents could improve the dispersion of the CaCO3in the rubber matrix remarkably, whereas borate coupling agent could not.The effect of modified nano-sized CaCO3on the dynamical mechanical properties was also studied. Incorporation of CaCO3reduced the glass transition temperature (Tg) of the vulcanizates. In comparison with nano-sized CaCO3, micron-sized CaCO3depressed the Tg more remarkably.

- Abstract
ABSTRACTClarithromycin (CLA) is a commonly recommended drug for Helicobacter pylorieradication. However, the prevalence of CLA-resistant H. pyloriis increasing. Although point mutations in the 23S rRNA are key factors for CLA resistance, other factors, including efflux pumps and regulation genes, are also involved in the resistance of H. pylorito CLA. Guanosine 3′-diphosphate 5′-triphosphate and guanosine 3′,5′-bispyrophosphate [(p)ppGpp)], which are synthesized by the bifunctional enzyme SpoT in H. pylori, play an important role for some bacteria to adapt to antibiotic pressure. Nevertheless, no related research involving H. pylorihas been reported. In addition, transporters have been found to be related to bacterial drug resistance. Therefore, this study investigated the function of SpoT in H. pyloriresistance to CLA by examining the shifts in the expression of transporters and explored the role of transporters in the CLA resistance of H. pylori. A ΔspoTstrain was constructed in this study, and it was shown that SpoT is involved in H. pyloritolerance of CLA by upregulating the transporters HP0939, HP1017, HP0497, and HP0471. This was assessed using a series of molecular and biochemical experiments and a cDNA microarray. Additionally, the knockout of genes hp0939, hp0471, and hp0497in the resistant strains caused a reduction or loss (the latter in the Δhp0497strain) of resistance to CLA. Furthermore, the average expression levels of these four transporters in clinical CLA-resistant strains were considerably higher than those in clinical CLA-sensitive strains. Taken together, our results revealed a novel molecular mechanism of H. pyloriadaption to CLA stress.

H. pylori can survive under a nutrition-deficient environment. During infection and transmission, H. pylori is confronted with nutrient limitation and the bacterium requires rapid alteration in gene expression for survival under stress conditions. However, the mechanism underlining this regulation remains unknown. A previous study showed that σ
54 is an important regulation factor for H. pylori survival in the nutrition-deficient environment. Our results show that the expression of σ54 (rpoN) is significantly induced in the stationary phase (nutrition deficiency) and the rpoN mutant showed a significantly lower viability than wild-type H. pylori in the late stationary phase. Thus, σ54 is involved in H. pylori survival during nutrient limitation. We used comparative proteomics to analyze the protein differentiation between wild-type and rpoN mutant during the stationary phase. With depleted nutrients, σ54 can slow the process of proliferation by negatively regulating genes involved in energy metabolism and biosynthesis and enhance stress-resistant ability by positively regulating genes involved in protein fate and redox reaction. Especially, NapA positively regulated by σ54 plays an important function in H. pylori survival both in the stationary phase and in water, and the latter situation would be beneficial for bacterial in vitro transmission. Our investigations give new light on the adaptive regulation of H. pylori under stress conditions. [ABSTRACT FROM AUTHOR]- Published

PROGRANULIN , *WOUNDS & injuries , *DIABETIC nephropathies - Abstract
Podocyte injury is considered a major contributor to the development of diabetic nephropathy (DN). Therefore, identification of potential therapeutic targets for preventing podocyte injury has clinical importance. Recent studies have indicated that autophagy is a key homeostatic mechanism to maintaining podocyte integrity and function. This study was to elucidate the role of progranulin (PGRN), a secreted glycoprotein, in the modulation of podocyte autophagic process and podocyte injury under a diabetic condition. PGRN was downregulated in the kidney from diabetic mice and podocytes under a high-glucose (HG) condition. PGRN deficiency exacerbated the renal dysfunction and glomerular structural alterations. In vitro, treatment with recombinant human PGRN (rPGRN) attenuated HG-induced podocyte injury accompanied by enhanced autophagy. Inhibition of autophagy disturbed the protective effects of PGRN in HG-induced podocytotoxicity. Furthermore, PGRN induced autophagy via the PGRN-CAMKK-AMPK pathway. Collectively, our data identified the protective role of PGRN in podocyte injury via restoring autophagy and activating the CAMKK-AMPK pathway, which may pave the road to new therapeutic modalities for the treatment of diabetic nephropathy. Key messages: • PGRN level is reduced in kidney of diabetic mice and high-glucose–treated podocytes. • PGRN deficiency exacerbates renal injury in diabetic mice. • PGRN protects against high-glucose–induced podocyte injury. • PGRN restores high-glucose–inhibited autophagy in podocytes. • CAMKK-AMPK pathway is required for the protective role of PGRN in podocyte injury.

Abstract Rapamycin (sirolimus) is employed as an immunosuppressant following liver transplant, to inhibit the re-growth of cancer cells following liver resection for hepatocellular carcinoma (HCC), and for the treatment of advanced HCC. Rapamycin also induces the expression of antioxidant enzymes in the liver, suggesting that pretreatment with the drug could provide a potential strategy to reduce ischemia reperfusion injury following liver surgery. The aim of this study was to further investigate the actions of rapamycin in inducing expression of the antioxidant enzymes heme oxygenase-1 (HO-1) and peroxiredoxin-1 (Prx-1) in normal liver and in tumorigenic liver cells. A rat model of segmental hepatic ischemia and reperfusion, cultured freshly-isolated rat hepatocytes, and tumorigenic H4IIE rat liver cells in culture were employed. Expression of HO-1 and Prx-1 was measured using quantitative PCR and western blot. Rapamycin pre-treatment of normal liver in vivo or normal hepatocytes in vitro led to a substantial induction of mRNA encoding HO-1 and Prx-1. The dose-response curve for the action of rapamycin on mRNA expression was biphasic, showing an increase in expression at 0 - 0.1 μM rapamycin but a decrease from maximum at concentrations greater than 0.1 μM. By contrast, in H4IIE cells, rapamycin inhibited the expression of HO-1 and Prx-1 mRNA. Oltipraz, an established activator of transcription factor Nrf2, caused a large induction of HO-1 and Prx-1 mRNA. The dose response curve for the inhibition by rapamycin of HO-1 and Prx-4 mRNA expression, determined in the presence of oltipraz, was monophasic with half maximal inhibition at about 0.01 μM. It is concluded that, at concentrations comparable to those used clinically, pre-treatment of the liver with rapamycin induces the expression of HO-1 and Prx-1. However, the actions of rapamycin on the expression of these two antioxidant enzymes in normal hepatocytes are complex and, in tumorigenic liver cells, differ from those in normal hepatocytes. Further studies are warranted to evaluate preconditioning the livers of patients subject to liver resection or liver transplant with rapamycin as a viable strategy to reduce IR injury following liver surgery. Highlights • Rapamycin induces expression of heme oxygenase-1 and peroxiredoxin-1 in hepatocytes. • Biphasic dose-response curve for antioxidant enzyme induction in normal hepatocytes. • Rapamycin inhibits expression of the antioxidant enzymes in tumorigenic liver cells. • Rapamycin pre-treatment may provide strategy to reduce liver ischemia reperfusion injury.

Abstract Rapamycin is employed as an immunosuppressant following organ transplant and, in patients with hepatocellular carcinoma, to inhibit cancer cell regrowth following liver surgery. Preconditioning the liver with rapamycin to induce the expression of antioxidant enzymes is a potential strategy to reduce ischemia reperfusion (IR) injury. However, pre-treatment with rapamycin inhibits bile flow, especially following ischemia. The aim was to investigate the mechanisms involved in this inhibition. In a rat model of segmental hepatic ischemia and reperfusion, acute administration of rapamycin by intravenous injection did not inhibit the basal rate of bile flow. Pre-treatment of rats with rapamycin for 24 h by intraperitoneal injection inhibited the expression of mRNA encoding the sinusoidal influx transporters Ntcp, Oatp1 and 2 and the canalicular efflux transporter Bsep, and increased expression of canalicular Mrp2. Dose-response curves for the actions of rapamycin on the expression of Bsep and Ntcp in cultured rat hepatocytes were biphasic, and monophasic for effects on Oatp1. In cultured tumorigenic H4IIE liver cells, several bile acid transporters were not expressed, or were expressed at very low levels compared to hepatocytes. In H4IIE cells, rapamycin increased expression of Ntcp, Oatp1 and Mrp2, but decreased expression of Oatp2. It is concluded that the inhibition of bile flow recovery following ischemia observed in rapamycin-treated livers is principally due to inhibition of the expression of sinusoidal bile acid transporters. Moreover, in tumorigenic liver tissue the contribution of tumorigenic hepatocytes to total liver bile flow is likely to be small and is unlikely to be greatly affected by rapamycin.

Cervical cancer is one of the most common gynecological tumors in the world, and human papillomavirus (HPV) infection is its causative agent. However, the molecular mechanisms involved in the carcinogenesis of cervical cancer still require clarification. Here we found that knockdown of Non-SMC (Structural Maintenance of Chromosomes) condensin I complex subunit H (NCAPH) gene expression significantly inhibited the proliferation, migration, invasion and epithelial–mesenchymal transition (EMT) of cervical cancer cells in vitro, and restrained xenograft tumor formation in vivo. Intriguingly, HPV E7 could form a positive feedback loop with NCAPH. E7 upregulated NCAPH gene expression via E2F1 which initiated NCAPH transcription by binding to its promoter directly. Silencing of NCAPH reduced E7 transcription via promoting the transition of AP-1 heterodimer from c-Fos/c-Jun to Fra-1/c-Jun. Moreover, the E7-mediated NCAPH overexpression was involved in the activation of the PI3K/AKT/SGK signaling pathway. In vivo, NCAPH expression in cervical cancer tissues was significantly higher than which in normal cervix and high-grade squamous intraepithelial lesion (HSIL) tissues, and its expression was significantly correlated with tumor size, depth of invasion and lymph node metastasis. Patients with high NCAPH expression had a significantly better survival outcomes than those with low-expression, suggesting that NCAPH-induced cell proliferation might sensitize cancer cells to adjuvant therapy. In conclusion, our results revealed the role of NCAPH in the carcinogenesis of cervical cancer in vitro and in vivo. The interaction between E7 and NCAPH expands the mechanism of HPV induced tumorigenesis and that of host genes regulating HPV E7.

H. pylori can survive under a nutrition-deficient environment. During infection and transmission, H. pylori is confronted with nutrient limitation and the bacterium requires rapid alteration in gene expression for survival under stress conditions. However, the mechanism underlining this regulation remains unknown. A previous study showed that σ54 is an important regulation factor for H. pylori survival in the nutrition-deficient environment. Our results show that the expression of σ54 (rpoN) is significantly induced in the stationary phase (nutrition deficiency) and the rpoN mutant showed a significantly lower viability than wild-type H. pylori in the late stationary phase. Thus, σ54 is involved in H. pylori survival during nutrient limitation. We used comparative proteomics to analyze the protein differentiation between wild-type and rpoN mutant during the stationary phase. With depleted nutrients, σ54 can slow the process of proliferation by negatively regulating genes involved in energy metabolism and biosynthesis and enhance stress-resistant ability by positively regulating genes involved in protein fate and redox reaction. Especially, NapA positively regulated by σ54 plays an important function in H. pylori survival both in the stationary phase and in water, and the latter situation would be beneficial for bacterial in vitro transmission. Our investigations give new light on the adaptive regulation of H. pylori under stress conditions. [ABSTRACT FROM AUTHOR]

- Abstract
Doxorubicin (DOX) is a chemotherapy drug widely used in clinical settings, acting as a first-line treatment for various malignant tumors. However, its use is greatly limited by the cardiotoxicity it induces, including doxorubicin-induced cardiomyopathy (DIC). The mechanisms behind DIC are not fully understood, but its potential biological mechanisms are thought to include oxidative stress, inflammation, energy metabolism disorders, mitochondrial damage, autophagy, apoptosis, and ferroptosis. Recent studies have shown that cardiac injury induced by DOX is closely related to ferroptosis. Due to their high efficacy, availability, and low side effects, natural medicine treatments hold strong clinical potential. Currently, natural medicines have been shown to mitigate DOX-induced ferroptosis and ease DIC through various functions such as antioxidation, iron ion homeostasis correction, lipid metabolism regulation, and mitochondrial function improvement. Therefore, this review summarizes the mechanisms of ferroptosis in DIC and the regulation by natural plant products, with the expectation of providing a reference for future research and development of inhibitors targeting ferroptosis in DIC. This review explores the mechanisms of ferroptosis in doxorubicin-induced cardiomyopathy (DIC) and summarizes how natural plant products can alleviate DIC by inhibiting ferroptosis through reducing oxidative stress, correcting iron ion homeostasis, regulating lipid metabolism, and improving mitochondrial function., (© 2024 John Wiley & Sons Ltd.)

- Abstract
Objectives: Tinea capitis remains a common fungal infection in children worldwide. Species identification is critical for determining the source of infection and reducing transmission. In conventional methods, macro- and microscopic analysis is time-consuming and results in slow fungal growth or low specificity. We propose a rapid real-time diagnostic PCR method that allows species-specific identification of dermatophytes, including the Microsporum canis complex, Trichophyton mentagrophytes complex, Trichophyton rubrum complex and Trichophyton tonsurans, in patients with tinea capitis., Methods: Hair and scrapings samples were collected from 231 patients with tinea capitis who were positive for fungal elements via direct microscopy with potassium hydroxide. Each sample was subjected to a two-step real-time PCR (RT-PCR) assay, which was designed on the basis of differences in the DNA fragments of the internal transcribed spacer (ITS) and β-tubulin covering the Microsporum canis complex, T. mentagrophyte complex, T. rubrum complex, T. tonsurans, T. verrucosum, T. schoenleinii and N. gypseum., Results: In total, 186/231 samples (80.52%) were positive for fungal culture. The two-step RT-PCR was positive in 215/231 samples (93.07%), among which 179 were culture positive. The combined efficacy was 96.81%, which was significantly different when the RT-PCR assays were performed in parallel with fungal culture. A total of 126 samples (54.55%) were identified as Microsporum canis by fungal culture, among which the positive rate of M. canis complex RT-PCR was 97.62% (123/126). A total of 45 samples were negative for fungal culture, of which 80.0% (36/45) were positive by RT-PCR, and the percentage of M. canis complex-positive samples was 53.33% (24/45). The RT-PCR assays were negative for 16/231 samples, among which 7 were culture positive, including M. canis (n = 3), T. violaceum (n = 3) and N. gypseum (n = 1)., Conclusion: We developed a new diagnostic assay system using a rapid real-time TaqMan PCR assay with specific primers that can be applied in routine laboratory practice for hair and skin samples of tinea capitis to detect dermatophytes and increase diagnostic efficiency., (© 2024 Wiley‐VCH GmbH.

- Abstract
Background: The ratio of non-high-density lipoprotein cholesterol to high-density lipoprotein cholesterol (NHHR) index is a relatively new composite lipid index, the relationship between NHHR and depression is unclear from the current study. The primary aim of our study was to examine the association between the prevalence of depression and NHHR in a US population., Methods: The National Health and Nutrition Examination Survey (NHANES) provided the data for our investigation from 2005 to 2018. and primarily included participants who contained complete data on NHHR and depression in U.S. adults (age ≥20 years). Associations between NHHR and depression were assessed using multifactorial logistic regression analysis, subgroup analysis, and smoothed curve fitting., Results: In our study, 29,561 subjects in total showed a mean NHHR index of 3.12± 1.58,A noteworthy positive correlation was observed between NHHR and depression in multifactorial logistic regression analysis. Subgroup analyses and tests of interaction showed that gender, age, ethnicity, PIR, smoking, alcohol consumption, coronary heart disease, diabetes mellitus, hypertension, and stroke did not influence the NHHR and the association between depression (P for interaction > 0.05), whereas two stratification factors, BMI and sleep disturbance, may be potential factors in the association between NHHR and depression (P for interaction < 0.05)., Conclusion: According to our present study, if the level of NHHR rises in American adults, their likelihood of developing depression also increases., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Yan, Wang, Liu, Fu and Zhou.)

- Abstract
Acute myocardial infarction (AMI) remains a leading cause of death among patients with cardiovascular diseases. Percutaneous coronary intervention (PCI) has been the preferred clinical treatment for AMI due to its safety and efficiency. However, research indicates that the rapid restoration of myocardial oxygen supply following PCI can lead to secondary myocardial injury, termed myocardial ischemia-reperfusion injury (MIRI), posing a grave threat to patient survival. Despite ongoing efforts, the mechanisms underlying MIRI are not yet fully elucidated. Among them, oxidative stress and inflammation stand out as critical pathophysiological mechanisms, playing significant roles in MIRI. Natural compounds have shown strong clinical therapeutic potential due to their high efficacy, availability, and low side effects. Many current studies indicate that natural compounds can mitigate MIRI by reducing oxidative stress and inflammatory responses. Therefore, this paper reviews the mechanisms of oxidative stress and inflammation during MIRI and the role of natural compounds in intervening in these processes, aiming to provide a basis and reference for future research and development of drugs for treating MIRI., (© 2024 John Wiley & Sons Ltd.)

- Abstract
Background: The Platelet to High-Density Lipoprotein cholesterol Ratio (PHR) is a novel indicator of inflammatory response and metabolic disorders, linked to various chronic diseases. This study aims to investigate the relationship between PHR and hypertension., Methods: Data from the National Health and Nutrition Examination Survey (NHANES), collected across seven consecutive cycles from 2005 to 2018, were analyzed. The dataset included participants' hypertension status as reported by a doctor, their use of antihypertensive medications, and the average of three blood pressure measurements to identify hypertensive adults, along with complete information for PHR calculation. PHR was calculated based on Platelet (PLT) count and High-Density Lipoprotein cholesterol (HDL-C) using the following formula: PHR = [PLT (1000 cells/µL) / HDL-C (mmol/L)]. A multivariable logistic regression model was employed to assess the association between PHR and hypertension, and subgroup analyses were conducted to explore potential influencing factors. Additionally, Restricted Cubic Spline (RCS) curves were applied for threshold effect analysis to describe nonlinear relationships., Results: Higher PHR was associated with an increased prevalence of hypertension. After adjusting for various covariates, including race, education level, Family Poverty Income Ratio (PIR), smoking, alcohol consumption, sleep disturbances, waist circumference, diabetes, coronary heart disease, angina, heart attack, and stroke, the results remained significant (OR = 1.36; 95% CI, 1.32, 1.41, P < 0.001). Participants with the highest PHR levels had a 104% higher risk of hypertension compared to those with the lowest PHR levels (OR = 2.04; 95% CI, 1.89, 2.21, P < 0.001)., Conclusion: Elevated PHR levels are strongly associated with an increased risk of hypertension. Specifically, when PHR is below 280, the risk of hypertension increases in proportion to PHR. This suggests that regular monitoring of PHR may help identify patients at risk of hypertension early, allowing for timely interventions to slow disease progression. Larger cohort studies are necessary to confirm these findings., (© 2024. The Author(s).)

- Abstract
Purpose: To evaluate the efficacy and safety of Shenmai injection for the treatment of viral myocarditis (VMS) through systematic evaluation and meta-analysis., Methods: Seven databases were searched to identify randomized controlled trials that examined the use of Shenmai injection for the treatment of VMS. The databases were searched from inception to 20 January 2024. The quality of the included studies was evaluated via the Cochrane risk of bias tool (RoB 2) version 2. Data analysis was performed using Review Manager 5.4 and Stata 16., Results: In total, 18 randomized controlled trials were included. The trials were conducted in 2006-2024 and included 1,661 patients with VMS. The results reveal that Shenmai injection combined with conventional treatment was superior to conventional treatment alone in terms of the following outcomes: total effective rate [RR = 1.22, 95% CI (1.16, 1.28)], CKMB [SMD = -3.33, 95% CI (-4.85, -1.81)], electrocardiogram (ECG) efficacy [RR = 1.30, 95% CI (1.20, 1.40)], AST [SMD = -0.70, 95% CI (-1.28, -0.11)], LDH [SMD = -1.17, 95% CI (-1.37, -0.97], p < 0.00001], CK [SMD = -1.74, 95% CI (-2.34, -1.13)], TNF-α [SMD = -1.35, 95% CI (-1.85, -0.84)], and IL-6 [SMD = -1.40, 95% CI (-1.76, -1.05)]. There were no significant differences in the incidence of adverse reactions [RR = 1.56, 95% CI (0.73, 3.33), p = 0.25] or cTnI levels [SMD = -3.35, 95% CI (-6.81, 0.11)] between the groups., Conclusion: Shenmai injection with conventional treatment can reduce the degree of myocardial injury in patients with VMS, weaken the inflammatory response and improve the clinical efficacy of the conventional treatment. This approach was found to be safe. However, additional high-quality studies are necessary to confirm the reliability of this treatment method., Systematic Review Registration: https://www.crd.york.ac.uk/PROSPERO/logout.php, identifier PROSPERO (CRD42024518665)., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Yang, Qin, Li, He and Zhou.)

- Abstract
Background: Coronary artery disease (CAD) has been a dominating reason of mortality globally due to its complexity of etiology. A variety of gastrointestinal disorders (GDs) have been accounted to be related to CAD. Thus, this study aims to determine their causal relationship by two-sample Mendelian randomization (MR) analysis., Methods: Single-nucleotide polymorphisms (SNPs) relevant to 22 GDs were employed as instrumental variables from the genome-wide association summary (GWAS) datasets. Genetic associations with CAD and HF were acquired from UK Biobank, FinnGen, and other GWAS studies. We conducted a univariable MR (UVMR) analysis followed by a meta-analysis. A multivariable MR (MVMR) analysis was then performed with smoking and body mass index (BMI) as justifications. Also, a bi-directional MR analysis was leveraged to verify the reverse causal correlations., Results: Generally, UVMR analyses separately observed the causal effects of GDs on CAD and HF. Genetic liability to gastroesophageal reflux disease displayed a positive association with both CAD (OR=1.19; 95%CI: 1.01-1.41) and HF (OR=1.22; 95%CI: 1.00-1.49) risk; genetic liability to celiac disease separately attributed to CAD (OR=1.02; 95%CI: 1.01-1.03) and HF (OR=1.01; 95%CI: 1.00-1.02), which also maintained after MVMR analysis. Besides, we observed mutually causal associations between CAD and celiac disease., Conclusion: Our work suggested that genetic susceptibility to some GDs might causally increase the risk of CAD and HF, emphasizing the importance of preventing CAD in patients with GDs., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Wang, Ban, Zhou and Qie.)

- Abstract
Background: Hair loss is common in hypothyroidism patients. However, the link with alopecia areata (AA) and androgenetic alopecia (AGA) is unclear. Previous observational studies have presented completely opposite results. This study aims to causally link hypothyroidism with AA and AGA., Methods: A two-sample Mendelian Randomization (MR) study, utilizing data from FinnGen Consortium, investigated the causal link between hypothyroidism and AA and AGA. We employed Inverse Variance Weighted (IVW), MR-Egger, Weighted Median, Simple Mode, and Weighted Mode to assess the risk association., Results: The discovery samples included 13,429 hypothyroidism cases (94,436 controls), 767 alopecia areata cases (394,105 controls), and 220 androgenetic alopecia cases (219,249 controls). MR analysis showed a causal link between hypothyroidism and AA, with significant results from IVW (OR, 1.34; CI, 1.16-1.56; P = 0.0001), MR-Egger (OR, 1.56; CI, 1.09-2.23; P = 0.0240), and weighted median (OR, 1.34; CI, 1.06-1.69; P = 0.0140). However, no clear causal relationship was found between genetically predicted hypothyroidism and AGA risk (p > 0.05)., Conclusion: The results show hypothyroidism causally associated with AA onset, but not AGA. These findings address contentious issues in observational studies. Comprehensive thyroid function assessments are crucial for AA patients, emphasizing thorough clinical examinations' importance., Competing Interests: The authors have no conflicts of interest to declare in this work., (© 2024 Zhang et al.)

Qin J, Yang Q, Wang Y, Shi M, Zhao X, and Zhou Y
- Abstract
Pyroptosis is a type of programmed cell death that is mediated by both typical and atypical pathways and ultimately leads to the lysis and rupture of cell membranes and the release of proinflammatory factors, triggering an intense inflammatory response. Heart failure (HF) is a serious and terminal stage of various heart diseases. Myocardial hypertrophy, myocardial fibrosis, ventricular remodeling, oxidative stress, the inflammatory response and cardiomyocyte ionic disorders caused by various cardiac diseases are all risk factors for and aggravate HF. Numerous studies have shown that pyroptosis can induce and exacerbate these reactions, causing progression to HF. Therefore, targeting pyroptosis is a promising strategy to treat HF. This paper summarizes the role of pyroptosis in the development of HF and the underlying mechanism involved. Recent research progress on the ability of traditional Chinese medicine (TCM) extracts and formulas to inhibit pyroptosis and treat HF was summarized, and some traditional Chinese medicine extracts and formulas can alleviate different types of HF, including heart failure with preserved ejection fraction (HFpEF), heart failure with reduced ejection fraction (HFrEF), and heart failure with midrange ejection fraction (HFmrEF), by targeting pyroptosis. These findings may provide new ideas and evidence for the treatment or adjuvant treatment of HF by targeting pyroptosis., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Qin, Yang, Wang, Shi, Zhao and Zhou.)

- Abstract
Heart failure is a complex syndrome characterized by progressive circulatory dysfunction, manifesting clinically as pulmonary and systemic venous congestion, alongside inadequate tissue perfusion. The early identification of HF, particularly at the mild and moderate stages (stages B and C), presents a clinical challenge due to the overlap of signs, symptoms, and natriuretic peptide levels with other cardiorespiratory pathologies. Nonetheless, early detection coupled with timely pharmacological intervention is imperative for enhancing patient outcomes. Advances in high-throughput omics technologies have enabled researchers to analyze patient-derived biofluids and tissues, discovering biomarkers that are sensitive and specific for HF diagnosis. Due to the diversity of HF etiology, it is insufficient to study the diagnostic data of early HF using a single omics technology. This study reviewed the latest progress in genomics, transcriptomics, proteomics, and metabolomics for the identification of HF biomarkers, offering novel insights into the early clinical diagnosis of HF. However, the validity of biomarkers depends on the disease status, intervention time, genetic diversity and comorbidities of the subjects. Moreover, biomarkers lack generalizability in different clinical settings. Hence, it is imperative to conduct multi-center, large-scale and standardized clinical trials to enhance the diagnostic accuracy and utility of HF biomarkers.

- Abstract
Introduction: Diabetes is a significant risk factor for cognitive impairment. Therefore, early identification of cognitive impairment in diabetic patients is particularly important. The aim of this study was to assess the relationship between Cardiometabolic index (CMI) and cognitive function in a diabetic population., Methods: A cross-sectional study was conducted by collecting information from the National Health and Nutrition Examination Survey (NHANES) 2011-2014. Multiple linear regression models were used to investigate the correlation between CMI and low cognitive function in a diabetic population. Threshold effects analysis and fitted smoothing curves were used to describe the nonlinear links. Interaction tests and subgroup analyses were also performed., Results: A total of 1,050 people participated in this study, including 561 men and 489 women. In the fully corrected model, CMI was positively associated with low cognitive performance as assessed by CERAD Word List Learning Test (CERAD W-L), Animal Fluency Test (AFT), and Digit Symbol Substitution Test (DSST) (OR = 1.37 [1.14, 1.72], p = 7.4 × 10-3), (OR = 1.21 [1.04, 1.51], p = 1.26 × 10-2), and (OR = 1.27 [1.08, 1.63], p = 2.53 × 10-2). Our study found that diabetic patients with higher CMI were at greater risk of developing low cognitive function. The effect of the subgroups on the positive association of CMI with cognitive impairment was not significant. A non-linear association between low cognitive performance and CMI was determined by CERAD W-L, AFT, and DSST (log-likelihood ratio <5 × 10-2). In addition, our also study found that CMI was a better predictor of cognitive impairment in diabetes than weight-adjusted waist index (WWI)., Conclusion: Increased CMI is associated with an increased risk of cognitive impairment in people with diabetes. CMI can be used as a new anthropometric measure for predicting cognitive impairment in diabetes, with stronger predictive power than WWI., (© 2024 S. Karger AG, Basel.)

- Abstract
Introduction: This systematic review examines the efficacy of a combination of Qi benefiting and blood circulation promoting herbs with Dapagliflozin in treating type 2 diabetes mellitus (T2DM) combined with heart failure (HF)., Methods: Randomized controlled trials (RCTs) assessing the combination of Qi benefiting and blood circulation promoting herbs with Dapagliflozin for T2DM and CHF was conducted. The search, spanning from the database's establishment to June 2023, included seven databases: China Knowledge Network (CNKI), Wanfang Database, VIP Database, PubMed, Embase, Cochrane Library, and the Chinese Biomedical Literature Database. Two researchers screened and extracted data based on inclusion and exclusion criteria. The Cochrane Handbook version 5.1 guided the quality assessment of studies, and the meta-analysis was performed using RevMan 5.4 software., Results: Eleven articles, encompassing a sample size of 1,192 cases, were included. Meta-analysis results indicated that combining Qi benefiting and blood circulation promoting herbs with Dapagliflozin improved the clinical efficacy rate (OR = 4.35, 95% confidence interval [CI; 2.98, 6.35], p < 0.00001). It reduced blood glucose levels, evidenced by decreased fasting blood glucose (FBG) (mean difference [MD] = -1.19, 95% CI [-1.30, -1.09], p < 0.00001), 2-h postprandial blood glucose (2hPG) (MD = -1.95, 95% CI [-2.09, -1.80], p < 0.00001), and glycosylated hemoglobin (HbA1c) (MD = -1.40, 95% CI [-1.49, -1.31], p < 0.00001). Inflammatory factors also reduced, including C-reactive protein (CRP) (MD = -4.93, 95% CI [-5.38, -4.48], p < 0.00001), tumor necrosis factor (TNF-α) (MD = -2.91, 95% CI [-3.32, -2.49], p < 0.00001), and interleukin-6 (IL-6) (MD = -11.10, 95% CI [-12.43, -9.43], p < 0.00001). Additionally, left ventricular end-diastolic diameter (LVEDD) (standardized mean difference [SMD] = -1.25, 95% CI [-1.45, -1.05], p < 0.00001), left ventricular end-systolic diameter (LVESD) (SMD = -1.34, 95% CI [-1.51, -1.13], p < 0.00001), and improved left ventricular ejection fraction (LVEF) (SMD = 2.92, 95% CI [2.65, 3.19], p < 0.00001), 6-min walk test (6MWT) (MD = 35.59, 95% CI [29.72, 41.47], p < 0.00001), and Minnesota Living with Heart Failure Questionnaire (MLHFQ) scores (MD = 35.59, 95% CI [29.72, 41.47], p < 0.00001) were observed. The incidence of adverse events also decreased (RR = 0.25, 95% CI [0.11, 0.56], p = 0.0007)., Conclusion: The combination of Qi benefiting and blood circulation promoting herbs with Dapagliflozin shows potential in treating patients with T2DM and HF, suggesting its use as adjunctive therapy in clinical practice. However, the limited number and quality of the included studies necessitate further high-quality research to confirm these findings., (© 2024 S. Karger AG, Basel.)
