The evidence that depressive and anxiety disorders confer a high relative risk (RR) for cardiovascular disease (CVD) development is clear and compelling. A cadre of inflammation, platelet activation and other biomarkers of endothelial dysfunction strongly suggest multiple and possibly interrelated mechanisms underlying this co-morbidity. Early detection of the vulnerability to develop CVD has become an urgent health issue. However, detection alone of vulnerability without proper therapeutic intervention aimed at reversing it, is merely of scientific interest. The evidence to date that antidepressant drugs, while highly efficacious in restoring euthymia, may not normalize the biomarkers of CVD vulnerability. Hence, there is a need to identify other pharmacologic interventions for depression. Quetiapine, due to its unique molecular structure and unique pharmacological profile, belongs to none of the known classes of antidepressants. However, quetiapine clearly has antidepressant and anti-anxiety efficacies. Now, we propose to explore whether quetiapine can reverse those pathophysiological changes occurring in mixed depression/anxiety that have been linked causally to the development of CVD. Accordingly, the primary purpose of this study is to compare C-Reactive Protein between the treatment and healthy control groups at 12 weeks post treatment.

Background: Triple-negative breast cancers (TNBCs) are characterized by poor prognosis, rapid progression to metastatic stage, and onset of resistance to chemotherapy. Neoadjuvant chemotherapy is commonly used to improve the surgical pathological complete response rate (pCR) in stage II-III triple-negative breast cancer. However, chemotherapy can lead to immune escape and drug resistance in breast cancer cells, while the toxic side effects significantly affect patients' quality of life. The combination of Chinese herbal medicine and chemotherapy can improve survival rates while alleviating chemotherapy-related adverse events. Xiaopi Granules were developed by Professor Lin Yi, a renowned Traditional Chinese Medicine doctor in the field of breast diseases. The investigators' preliminary research has confirmed that Xiaopi Granules can inhibit tumor progression by targeting TAMs/CXCL1 signaling to suppress chemotherapy-induced autophagy, as well as inhibit the formation of tumor stem cells and pre-metastatic niches. Chinese medicine granules not only have several advantages compared to decoction, such as reliable drug quality and convenient administration but also have the characteristics of individualized prescription. However, whether their efficacy is comparable to that of the decoction granules still requires exploration. The investigators aimed to compare the efficacy of xiaopi granules and decoction in improving the pathological complete response of neoadjuvant chemotherapy of triple-negative breast cancer.

Hypothesis: Xiaopi granules can improve the pathological complete response of neoadjuvant chemotherapy of triple-negative breast cancer.

Patients and methods: Ninety patients with TNBC will be enrolled in this study and randomized to xiaopi granules plus neoadjuvant chemotherapy, xiaopi decoction plus neoadjuvant chemotherapy, or placebo plus neoadjuvant chemotherapy. The primary aim is the rate of pathological complete response (pCR, defined as the absence of invasive cells in breast and lymph nodes). The secondary outcome included genomics of plasma extracellular vesicles, plasma metabolites and metabolomics, urine metabolomics, fecal intestinal flora tests, pathological tissue genomics, functional assessment of cancer Therapy-Breast(FACT-B), and safety( AE and SAE). The neoadjuvant chemotherapy is carried out based on the National Comprehensive Cancer Network (NCCN) guidelines. Different treatments and doses are set according to the standard recommendations outlined in the guidelines. In addition to receiving neoadjuvant chemotherapy, the participants will be subjected to Xiaopi granules or decoction orally at a dosage of 18g per bag, twice daily, for a total of 8 days per treatment course. The duration of the treatment course will align with that of the chemotherapy regimen. A placebo is a look-alike substance that contains no active drug.
Amiodarone (5 mg / kg EV in 30 minutes) will be the drug of choice in the Restricted group blinded to the principal investigator. If there is no reversal / control and there is no adverse event, a further dose of the same previously administered medicinal product will be performed within 30 minutes, amiodarone 3 mg / kg. After the second dose, continuous infusion of amiodarone at a dose of 900 mg in 24 hours will be initiated. Administration of the drug will be blinded within the first hour to the principal investigator.
The hypoxia inducible factor-1 (HIF-1) transcription factor is an important regulator of the cellular response to hypoxia. The activity of HIF-1 is regulated by the level of the HIF-1α subunit, HIF-1α, which is rapidly degraded under normoxic conditions by the ubiquitin-proteasome pathway. HIF-1α levels increase under hypoxic conditions. Many human cancers also show constitutively increased HIF-1α levels. PX-478 or S-2-amino-3-[4′-N,N,-bis(2-chloroethyl)amino]phenyl propionic acid N-oxide dihydrochloride, is a novel anticancer agent, and is capably of decreasing both constitutive and hypoxia induced HIF-1α protein levels and HIF-1 transactivation in vitro and in vivo. In method embodiments, the administration of PX-478 is independent of the pathways of HIF-1α regulation involving the von Hippel-Lindau protein and p53. PX-478 causes an increase in polyubiquitinated HIF-1α levels due to inhibition of HIF-1α deubiquitination. The levels of other proteins whose proteasomal breakdown is mediated by ubiquitination are not affected by PX-478. Deubiquitination is a novel pathway for the regulation of cellular HIF-1α levels and PX-478 is a specific inhibitor of the pathway. Therapeutic compounds for regulating cellular HIF-1α levels and methods of regulating cellular HIF-1α levels are herein provided.

PURPOSE:To obtain an antitumor substance, by extracting yeast of Kluyveromyces genus with a basic aqueous solution, adjusting the pH of the extract to a specific level with an acid and extracting the objective substance from the resultant precipitate with a lipid-dissolving organic solvent. CONSTITUTION:A yeast belonging to Kluyveromyces genus (e.g. Kluyveromyces lactis, Kluyveromyces fragilis, etc.) is extracted with a basic aqueous solution and the extracted liquid is adjusted to 3.0-6.5pH with an acid such as hydrochloric acid. The obtained precipitate is collected by filtration or centrifugal separation, optionally dried and extracted with a lipid-dissolving organic solvent (e.g. methanol, ethanol, propanol, acetone, benzene, chloroform, etc.) to obtain the objective antitumor substance. The substance contains lipid as a main constituent component. 2/3 of the lipid component is simple lipid such as cholesterol, neutral fat, fatty acid, carotinoid, etc., and the remaining 1/3 is composite lipid such as glycerophospholipid.
This group has no intervention. Evaluations were only made at the start and at the end of 3-week long.
Patients receive aprepitant 125 mg orally once daily on day 1 and 80 mg orally once daily on days 2 and 3. Beginning 1 hour after receiving aprepitant, patients receive an infusion of cyclophosphamide on day 1. During course 2, patients crossover and receive treatment as in arm II.
Patients received salmeterol 50 μg delivered via the salmeterol proprietary dry powder inhalation device bis in die (bid, twice daily), once in the morning (between 07:00 and 11:00 AM) and once in the evening (between 7:00 and 11:00 PM). In addition to salmeterol 50 μg, patients received 2 indacaterol placebo inhalations in the morning. Daily inhaled corticosteroid treatment (if applicable) was to remain stable throughout the study. The short-acting β2-agonist salbutamol/albuterol was available for rescue use throughout the study.
Venovenous bypass (VVB) use during liver transplantation (LT) is notably variable among the centres and it is actually restricted to surgically complex cases, severely unstable recipients or grafts from high-risk donors. Historically, VVB was associated with the classical LT with caval cross clamping, while not much is known about the safety of this technique applied to piggyback LT. This retrospective observational study evaluated the effects of VVB applied to piggyback LT on mortality, hospital outcomes, postoperative graft and other organ dysfunction. We retrospectively collected data about recipient status, surgical complexity and graft quality of all the piggyback LTs performed at the Transplant Unit of IRCCS Azienda Ospedaliero-Universitaria di Bologna, Italy, from January 2012 to December 2022. A propensity score (PS) was built taking into account the variables possibly associated with either VVB choice and the investigated outcomes with the average treatment overlap method. PS-weighted general linear models (GLMs) were developed to investigate the adjusted effect of VVB use on the selected outcomes. The final analysis included 874 LT cases, of whom 74 (8.5%) underwent VVB. The effective sample sizes after PS-weighting were 280.2 and 64.3 patients in the no-VVB and VVB groups, respectively. PS-weighted GLMs did not show any differences regarding hospital and graft-related outcomes. However, significantly higher odds ratios for serum creatinine > 2 mg/dL and AKIN stage 2 or 3 during the first 24 h after ICU admission together with a higher renal replacement therapy need during ICU stay were reported for VVB exposure in the weighted analyses. This study suggests similar mortality and length of stay but a higher risk for postoperative acute kidney injury in patients undergoing piggyback LT with VVB.
BACKGROUND AND PURPOSE: This study analyses whether first-line antihypertensive drugs ameliorate the dysbiosis state in hypertension, and to test if this modification contributes to their blood pressure (BP) lowering properties in a genetic model of neurogenic hypertension.
EXPERIMENTAL APPROACH: Twenty-week-old male Wistar Kyoto rats (WKY) and spontaneously hypertensive rats (SHR) were untreated or treated with captopril, amlodipine or hydrochlorothiazide. A faecal microbiota transplantation (FMT) experiment was also performed by gavage of faecal content from donor SHR-treated groups to SHR recipients for 3 weeks.
KEY RESULTS: Faeces from SHR showed gut dysbiosis, characterized by lower acetate- and higher lactate-producing bacteria and lower strict anaerobic bacteria. All three drugs increased the anaerobic bacteria proportion, captopril and amlodipine restored the proportion of acetate-producing bacterial populations to WKY levels, whereas hydrochlorothiazide decreased butyrate-producing bacteria. Captopril and amlodipine decreased gut pathology and permeability and attenuated sympathetic drive in the gut. Both drugs decreased neuroinflammation and oxidative stress in the hypothalamic paraventricular nuclei. Hydrochlorothiazide was unable to reduce neuroinflammation, gut sympathetic tone and gut integrity. FMT from SHR-amlodipine to SHR decreased BP, ameliorated aortic endothelium-dependent relaxation to acetylcholine, lowered NADPH oxidase activity, aortic Th17 infiltration and reduced neuroinflammation, whereas FMT from SHR-hydrochlorothiazide did not have these effects.
CONCLUSIONS AND IMPLICATIONS: First-line antihypertensive drugs induced different modifications of gut integrity and gut dysbiosis in SHR, which result in no contribution of microbiota in the BP lowering effects of hydrochlorothiazide, whereas the vasculo-protective effect induced by amlodipine involves gut microbiota reshaping and gut-immune system communication.
Obesity (OB) is a prevalent metabolic disorder. With the advancement of the economy, the prevention and treatment of obesity is a big problem for the global community. The methods to lose weight include exercise, diet, medicine, and surgery. Compared with other methods, diet regulation is safer and more effective. Hawthorn fruit has the effect of reducing weight, but the mechanism of effectiveness are not clear. In this study, obesity model rats are used to conduct scientific pharmacological research on hawthorn flavonoids. Hawthorn flavonoids can effectively improve the body weight, lipid accumulation, and lipid levels of obese rats. The contents of the colon of rats are analyzed using 16S rDNA sequencing technology. The intestinal microflora in obese rats changed significantly after flavonoids treatment, and they tended to be the control group. Based on liquid chromatography-mass spectrometry, serum metabolomics showed that the metabolites in the serum changed significantly, after hawthorn flavonoids treatment. Hawthorn flavonoids are especially involved in the biological processes of grade bile acid biosynthesis, histidine metabolism, and lipid metabolism. Pearson correlation analysis showed that the disorder of intestinal microorganisms is connected to changes in serum metabolites. These findings give a new idea about how hawthorn flavonoids help with obesity.

GRK5 holds a pivotal role in cellular signaling pathways, with its overexpression in cardiomyocytes, neuronal cells, and tumor cells strongly associated with various chronic degenerative diseases, which highlights the urgent need for potential inhibitors. In this study, multiclass classification-based QSAR models were developed using diverse machine learning algorithms. These models were built from curated compounds with experimentally derived GRK5 inhibitory activity. Additionally, a pharmacophore model was constructed using active compounds from the dataset. Among the models, the SVM-based approach proved most effective and was initially used to screen DrugBank compounds within the applicability domain. Compounds showing significant GRK5 inhibitory potential underwent evaluation for key pharmacophoric features. Prospective compounds were subjected to molecular docking to assess binding affinity towards GRK5's key active site amino acid residues. Stability at the binding site was analyzed through 200 ns molecular dynamics simulations. MM-GBSA analysis quantified individual free energy components contributing to the total binding energy with respect to binding site residues. Metadynamics analysis, including PCA, FEL, and PDF, provided crucial insights into conformational changes of both apo and holo forms of GRK5 at defined energy states. The study identifies DB02844 (S-Adenosyl-1,8-Diamino-3-Thiooctane) and DB13155 (Esculin) as promising GRK5 inhibitors, warranting further in vitro and in vivo validation studies.
The invention provides a camptothecin medical lipidosome composition. The camptothecin medical lipidosome composition is prepared from the following raw materials and supplementary materials in parts by weight: 5 to 25 parts of camptothecin medicine, 40 to 100 parts of phospholipid, 6 to 50 parts of cholesterol, 1 to 8 parts of vitamin E, and 10 to 100 parts of amino compound. According to a preparation method of the camptothecin medical lipidosome composition, the camptothecin medical lipidosome composition is prepared in a multi-emulsion way and an inverted evaporation way. The aqueous solution of the amino compound has a solubilizing effect respect to the camptothecin medicine, and can generate a water-soluble compound under the effect of intermolecular interaction or ionic bond effect. The compound is stable in physiological pH (Potential of Hydrogen) and higher in solution concentration, and can be wrapped in the inner cavity of lipidosome, therefore, the amount of the medicine in transfer can be increased, and the problem that the lactonic-ring type camptothecin medicine is subjected to high ring opening to result in leakage due to the influence of the pH and the plasma proteins can be avoided. The compound is stably wrapped in the lipidosome, and can reach the tumor part under the targeting effect of the lipidosome and then act in form of lactonic ring under the acidic condition of the tumor cells; and the compound has the advantages of increasing effect and reducing toxicity.
NAFLD is the most prevalent of all liver disorders and is the most common cause of chronic aminotransferase elevations in the U.S. With the availability of highly effective ART, chronic liver disease has become a leading cause of non-AIDS related morbidity and mortality in PLWH. NAFLD is projected to become the leading cause of liver disease in the aging HIV population. While there is evidence that both Hepatitis B and Hepatitis C infection follow an accelerated course in PLWH, it is unknown if NAFLD is also accelerated in PLWH. Unlike NAFLD in the general population, there is a significant lack of characterization of the natural history of NAFLD in PLWH. This prospective observational study of PLWH with NAFLD will examine the natural history of HIV-associated NAFLD. It will also test the accuracy of non-invasive assessments of advanced fibrosis in detecting histologically confirmed advanced fibrosis in PLWH, and establish a robust biospecimen bank (plasma, serum, genomic DNA, and urine; peripheral blood mononuclear cells (PBMCs) and stool at select sites).
Wound infection is an inflammatory response of the host to pathogenic microorganisms. It is a complex pathological process that may manifest either as a rapid onset acute wound infection, or as a prolonged chronic wound infection. Infectious wounds refer to acute or chronic wounds where infection has occurred, and their diagnosis and treatment involve many links, any loopholes in any aspect can lead to treatment failure. How to improve the diagnosis and treatment level of infectious wounds? This article proposed and discussed several issues, such as biofilm and drug resistance of bacteria, new materials and new-type dressings, special types of infectious wounds, and the combined application of various treatment techniques that need attention, and intended to attract the attention of peers. At the same time, it advocated for full attention to research results in the relevant fields and continuously emerging new technologies, concepts, materials, and methods, and applying them to the diagnosis and treatment of infectious wounds to benefit the majority of patients.

Patients in sham-EA group receive sham-EA at sham-Shuigou and sham-Yintang.Acupuncture needles are inserted into the adhesive pads but do not pierce the skin. Paired electrodes from the EA apparatus via sham connecting cords are clipped to the needle handles at sham-Shuigou and sham-Yintang. The sham connecting cords are similar in appearance to the normal ones, but the inner wires in sham connecting cords are cut off and cannot conduct electricity. All patients receive sham-EA at 9 am for 30 minutes once a day for consecutive 14 days.
Adult mammalian cardiomyocytes have minimal cell cycle capacity, which leads to poor regeneration after cardiac injury such as myocardial infarction. Many positive regulators of cardiomyocyte cell cycle and cardioprotective signals have been identified, but extracellular signals that suppress cardiomyocyte proliferation are poorly understood. We profiled receptors enriched in postnatal cardiomyocytes, and found that very-low-density-lipoprotein receptor (Vldlr) inhibits neonatal cardiomyocyte cell cycle. Paradoxically, Reelin, the well-known Vldlr ligand, expressed in cardiac Schwann cells and lymphatic endothelial cells, promotes neonatal cardiomyocyte proliferation. Thrombospondin1 (TSP-1), another ligand of Vldlr highly expressed in adult heart, was then found to inhibit cardiomyocyte proliferation through Vldlr, and may contribute to Vldlr's overall repression on proliferation. Mechanistically, Rac1 and subsequent Yap phosphorylation and nucleus translocation mediate the regulation of the cardiomyocyte cell cycle by TSP-1/Reelin-Vldlr signaling. Importantly, Reln mutant neonatal mice displayed impaired cardiomyocyte proliferation and cardiac regeneration after apical resection, while cardiac-specific Thbs1 deletion and cardiomyocyte-specific Vldlr deletion promote cardiomyocyte proliferation and are cardioprotective after myocardial infarction. Our results identified a novel role of Vldlr in consolidating extracellular signals to regulate cardiomyocyte cell cycle activity and survival, and the overall suppressive TSP-1-Vldlr signal may contribute to the poor cardiac repair capacity of adult mammals.
