Curcumin reverses cognitive deficits through promoting neurogenesis and synapse plasticity via the upregulation of PSD95 and BDNF in mice.

Following prolonged exposure to hypoxic conditions, for example, due to ascent to high altitude, aging or stroke, cognitive deficits can develop. The exact nature and genesis of hypoxia-induced cognitive deficits remain unresolved. Curcumin has been reported to stimulate neurogenesis and reduce neuronal degeneration.

JiangyaTongluo decoction ameliorates tubulointerstitial fibrosis via regulating the SIRT1/PGC-1α/mitophagy axis in hypertensive nephropathy.

Introduction: With the increasing prevalence of hypertension, the incidence of kidney diseases is also increasing, resulting in a serious public burden. Jiangya Tongluo decoction (JYTL), a recognized prescription in traditional Chinese medicine (TCM), is commonly used to calm an overactive liver and reduce excess yang, while also promoting blood flow to alleviate obstructions in the meridians. Previous research has indicated that JYTL may help mitigate kidney damage caused by hypertension; however, the underlying mechanisms have not been thoroughly assessed.

Prediction of miRNA-disease associations based on PCA and cascade forest.

Background: As a key non-coding RNA molecule, miRNA profoundly affects gene expression regulation and connects to the pathological processes of several kinds of human diseases. However, conventional experimental methods for validating miRNA-disease associations are laborious. Consequently, the development of efficient and reliable computational prediction models is crucial for the identification and validation of these associations.

[Research progress on indirect action and mechanism of traditional Chinese medicine based on gut-gut microbiota-target organ talks].

Traditional Chinese medicine(TCM) has been treating diseases for thousands of years and still holds an irreplaceable position in modern disease treatment. The composition of TCM is complex, and its mode of action features multi-pathway and multi-target characteristics, making its pharmacological actions and mechanisms complicated. The principles and mechanisms of TCM have always been a hot topic among scholars from various fields.

Hydrogen restores central tryptophan and metabolite levels and maintains mitochondrial homeostasis to protect rats from chronic mild unpredictable stress damage.

Background And Purpose: The field of hydrogen medicine has garnered extensive attention since Professor Ohsawa established that low concentrations of hydrogen (2%-4%) exert antioxidant effects. The present study aimed to evaluate the therapeutic effect of molecular hydrogen in a CUMS rat model.

Methods: A total of 40 SD rats were randomly divided into a control group, a model group, a hydrogen group, and a positive drug group.

Rapid Identification of Chemical Constituents in New Compound Aloe Capsule Based on UPLC-Q-Orbitrap-MS.

Rationale: The chemical composition of the new compound aloe capsule (NCAC) has not been fully elucidated to date, which poses challenges for pharmacology, scientific, and rational drug use. In this study, a rapid and sensitive method was established to comprehensively study the constituents in the NCAC. The contents of the NCAC were analyzed by UPLC-Q-Orbitrap-MS and data postprocessing technology.

Spatial shifts on a hyperbolic metasurface of graphene grating/topological insulators.

We theoretically study the Goos-Hänchen (GH) and Imbert-Fedorov (IF) shifts of a reflected Gaussian beam from a hyperbolic metasurface composed of graphene grating based on topological insulators (TIs). Perturbations are generated on the surface of TIs by applying a thin magnetic film, resulting in a broken time-reversal symmetry. The GH and IF shifts are greatly enhanced as a result of the combined interaction of the graphene grating and the topological magnetoelectric effect (TME).

Transoral penetrating craniocerebral injury: a case report and literature review.

A penetrating brain injury is a rare type of neurosurgical trauma associated with extremely high mortality and disability rates. Penetrating skull base injuries caused by arrows seldom occur because injuries caused by such weapons are more likely to be accidental. However, the number of self-inflicted injuries is increasing, and these injuries have varying patterns and high mortality rates.

Ethanol extracts of Cinnamomum migao H.W. Li attenuates neuroinflammation in cerebral ischemia-reperfusion injury via regulating TLR4-PI3K-Akt-NF-κB pathways.

Ethnopharmacological Relevance: Cinnamomum migao H.W. Li, commonly known as migao (MG), is used in the Miao region of China for treating cardiovascular and cerebrovascular diseases, attributed to its detoxifying (Jiedu in Chinese), activating blood circulation (Huoxue in Chinese), and promoting Qi circulation (Tongqi in Chinese) properties.

An ultrasensitive multimodal intracranial pressure biotelemetric system enabled by exceptional point and iontronics.

The accurate monitoring of vital physiological parameters, exemplified by heart rate, respiratory rate, and intracranial pressure (ICP), is of paramount importance, particularly for managing severe cranial injuries. Despite the rapid development of implantable ICP sensing systems over the past decades, they still suffer from, for example, wire connection, low sensitivity, poor resolution, and the inability to monitor multiple variables simultaneously. Here, we propose an ultrasensitive multimodal biotelemetric system that amalgamates an iontronic pressure transducer with exceptional point (EP) operation for the monitoring of ICP signals.

Therapeutic effects of Mudan granules on diabetic retinopathy: Mitigating fibrogenesis caused by FBN2 deficiency and inflammation associated with TNF-α elevation.

Ethnopharmacological Relevance: Mudan granules (MuD), a time-honored traditional Chinese patent medicine (TCPM), are widely utilized in the clinical treatment of diabetic peripheral neuropathy (DPN). In the field of biomedical diagnostics, both diabetic retinopathy (DR) and DPN are recognized as critical microvascular complications associated with diabetes. According to the principles of traditional Chinese medicine (TCM), these conditions are primarily attributed to a deficiency in Qi and the obstruction of collaterals.

Study on medical dispute prediction model and its clinical-application effectiveness based on machine learning.

Background: Medical dispute is a global public health issue, which has been garnering increasing attention. In this study, we used machine learning (ML) method to establish a dispute prediction model and explored the clinical-application efficiency of this model in effectively reducing the occurrence of medical disputes.

Methods: Retrospective study of All disputes filed by Gansu Medical Mediation Committee from 2019 to 2021 and patients with the same hospital level as that of the dispute group and hospitalization year were randomly selected as the control group in 1:1 ratio.

Insulin-like growth factor 2 targets IGF1R signaling transduction to facilitate metastasis and imatinib resistance in gastrointestinal stromal tumors.

Background: Gastrointestinal stromal tumors (GISTs) are typical gastrointestinal tract neoplasms. Imatinib is the first-line therapy for GIST patients. Drug resistance limits the long-term effectiveness of imatinib.

High throughput mRNA sequencing reveals potential therapeutic targets of Si-Ni-San in the pons for a stress-induced depression model.

Background: An accumulating body of research indicates that the pons is related to the occurrence of depression. Si-Ni-San (SNS) is a well-known Chinese herbal formula that is used to treat depression. Chinese herbal formulae have multiple therapeutic characteristics.

Targeting hTERT Promoter G-Quadruplex DNA Structures with Small-Molecule Ligand to Downregulate hTERT Expression for Triple-Negative Breast Cancer Therapy.

Human telomerase reverse transcriptase (hTERT) may have noncanonical functions in transcriptional regulation and metabolic reprogramming in cancer cells, but it is a challenging target. We thus developed small-molecule ligands targeting hTERT promoter G-quadruplex DNA structures (hTERT G4) to downregulate hTERT expression. Ligand showed high affinity toward hTERT G4 ( = 1.
