Objective: Lavender is used in herbal medicine for different therapeutic purposes. Nonetheless, potential therapeutic effects of this plant in ischemic heart disease and its possible mechanisms remain to be investigated.
Materials And Methods: In this experimental study, lavender oil at doses of 200, 400 or 800 mg/kg was administered through gastric gavage for 14 days before infarct-like myocardial injury (MI). The carotid artery and left ventricle were cannulated to record arterial blood pressure (BP) and cardiac function. At the end of experiment, the heart was removed and histopathological alteration, oxidative stress biomarkers as well as tumor necrosis factor-alpha (TNF-α) level were evaluated.
Results: Induction of M.I caused cardiac dysfunction, increased levels of lipid peroxidation, TNF-α and troponin I in heart tissue (P<0.001). Pretreatment with lavender oil at doses of 200 and 400 mg/kg significantly reduced myocardial injury, troponin I and TNF-α. In addition, it improved cardiac function and antioxidant enzyme activity (P<0.01).
Conclusion: Our finding showed that lavender oil has cardioprotective effect through inhibiting oxidative stress and inflammatory pathway in the rat model with infarct-like MI. We suggest that lavender oil may be helpful in prevention or attenuation of heart injury in patients with high risk of myocardial infarction and/or ischemic heart disease.

Background: Gliomas, particularly glioblastoma (GBM), are the most common and aggressive primary brain tumors in adults, characterized by high malignancy and frequent recurrence. Despite standard treatments, including surgery, radiotherapy, and chemotherapy, the prognosis for GBM remains poor, with a median survival of less than 15 months and a five-year survival rate below 10%. Tumor heterogeneity and resistance to treatment create significant challenges in controlling glioma progression.

Background: Traditional grading systems have proven inadequate in stratifying chRCC patients based on recurrence risk. Recently, several novel grading schemes, including three-tiered, two-tiered, and four-tiered systems, have been proposed, but their prognostic value remains controversial and lacks external validation.
Materials And Methods: We included 528 patients with pathologically proven chRCC (chromophobe renal cell carcinoma) from multiple medical institutions and the Cancer Genome Atlas-Kidney Chromophobe cohort.

This report aimed to analyze the potential effects of cytokines and neutrophils-to-lymphocytes ratio (NLR) on the occurrence of febrile seizures (FS) in children during the epidemic of novel coronavirus and influenza virus. Between July 2022 and April 2023, clinical data of 422 children with FS hospitalized in the Pediatrics, Shaoxing People's Hospital and the First Affiliated Hospital of Shaoxing University, during the epidemic and non-epidemic periods of novel coronavirus and influenza virus were analyzed. By comparing the various clinical characteristics of children with FS at different periods, comparison of variations in peripheral blood cell count, neutrophils, lymphocytes, hypersensitive C-creation protein, NLR, and inflammatory cytokines.

Chemotherapy is one of the most widely used anticancer treatments worldwide. However, despite its clinical effectiveness, most chemotherapeutic agents are associated with severe side effects. To address this limitation, there is an urgent need for the development of novel anticancer agents.

Background: The submental artery island flap (SIF) is a valid option for palatal reconstruction. However, the main limitation for its application for palatal defects is the arc of rotation. A novel modification for tunneling of the antegrade design of SIF that allows a compliant easy reach to the defect is described.
