OBJECTIVE To investigate the effects and mechanisms of Buyang huanwu decoction （BYHWD） and its active fractions in ameliorating non-alcoholic fatty liver disease. METHODS BYHWD and its effective fractions obtained through ethanol precipitation， as well as 30% ethanol， 50% ethanol， and 75% ethanol fractions （namely， the CC effective fraction， 30YC effective fraction， 50YC effective fraction， and 75YC effective fraction）， were prepared. These preparations were administered to rats via intragastric administration to prepare corresponding drug-containing serum （blank serum and simvastatin-containing serum were prepared using the same protocol）. Human L02 hepatocytes were divided into control group， model group， simvastatin-containing serum group， BYHWD-containing serum group， CC-containing serum group， 30YC-containing serum group， 50YC-containing serum group， and 75YC-containing serum group. Except for the control group， other groups were given 0.2 mol/L oleic acid for 24 h to induce a lipid accumulation model， and then intervened with 20% drug-containing serum/blank serum for 24 h. The lipid deposition in cells was observed， and the proportion of lipid droplet area was calculated； the levels of triglycerides （TG） and indicators of oxidative stress [malondialdehyde （MDA）， superoxide dismutase （SOD）] as well as liver function [alanine amino- transferase （ALT）， aspartate amino-transferase （AST）] in cells were detected； protein and mRNA expressions of AMP-activated protein kinase （AMPK）/sterol regulatory element-binding protein-1 （SREBP-1）/glycerol-3-phosphate acyltransferase （GPAT） signaling pathway were also measured. RESULTS Compared with the control group， cells in the model group exhibited severe cellular steatosis， with a significantly increased proportion of lipid droplet area， as well as the elevated levels of TG， ALT， AST， and MDA in cells， along with significantly up-regulated mRNA and protein expression levels of SREBP-1 and GPAT （P＜0.05）. The level of SOD， mRNA expression of AMPK， as well as the protein phosphorylation level of AMPK were decreased significantly （P＜0.05）. Compared with the model group， cellular steatosis was alleviated in all drug-containing serum groups， and the levels of most of the aforementioned quantitative indicators were significantly reversed （P＜0.05）. CONCLUSIONS BYHWD and its active fractions can exert a therapeutic effect on improving non-alcoholic fatty liver disease by regulating the AMPK/SREBP-1/GPAT signaling pathway， inhibiting oxidative stress responses， and reducing lipid deposition.

Objectives:Recently,domestical developed left ventricular assist devices(LVAD)have been frequently introduced into clinical practice.This study aims to report the anesthesia protocol and perioperative outcomes in Chinese patients receiving LVAD implantation surgery.Methods:This retrospective analysis included patients who underwent LVAD implantation at our center from June 2017 to November 2024.During and after separation from cardiopulmonary bypass,we optimized right heart function through careful adjustments in heart rate,rhythm,preload,myocardial contractility,and afterload.Vasoactive agents were administered as needed,and mechanical ventilation parameters were optimized.We implemented blood conservation strategies and established strict transfusion criteria to minimize allogenic blood transfusions.Results:A total of 100 patients were included in the analysis,with 54.0%classified as Interagency Registry for Mechanically Assisted Circulatory Support(INTERMACS)I or II.Before leaving the operating room,the mean arterial pressure(MAP),mean pulmonary arterial pressure(mPAP),central venous pressure(CVP),lactic acid levels,and urinary output after cardiopulmonary bypass were recorded as(74±7)mmHg,(25±7)mmHg,(7±3)mmHg,(2.3±1.9)mmol/L,and(8.2±5.4)ml/(kg·h),respectively.The transfusion rates for red blood cells and fresh frozen plasma were 20.0%and 28.0%.The in-hospital mortality rate was 3.0%,with a low incidence of severe complications including right heart failure(12%).Left ventricular ejection fraction increased from(23.7±4.8)%preoperatively to(25.3±10.5)%prior to discharge.Conclusions:Patients who received LVAD at our center exhibited low rates of postoperative mortality and complications and significant improvement in left heart function before discharge.

Uterine arteriovenous fistula (UAVF), a relatively rare vascular anomaly, may lead to life-threatening hemorrhage and poses diagnostic and management challenges for primary hospitals during initial encounters. This article reports four cases of UAVF treated with Drospirenone and ethinyl estradiol tablets at Department of Gynaecology, Zhuji Maternal and Child Health Hospital between 2023 and 2024. Combined with literature review, we systematically analyzed the etiological mechanisms, clinical characteristics, and diagnostic-therapeutic strategies of this condition, with particular focus on evaluating the efficacy and safety of conservative pharmacological management. By summarizing case features and individualized treatment protocols, this study aims to provide clinical references for early identification, accurate diagnosis, and rational intervention of UAVF, thereby reducing risks of massive hemorrhage and long-term complications while improving patient prognosis.

Retinopathy caused by myopia is the first cause of irreversible blinding eye disease in China.The TCM methods to prevent and control myopia mainly include Chinese materia medica and TCM appropriate techniques,which have the advantages of good efficacy,simple operation,and few adverse reactions.This paper believed that internal and external pathogenic factors act on the brain and eyes,breaking their homeostasis,leading to rhythmic disorders,and imbalance of essence,qi and blood is the main pathogenesis of myopia.Based on the idea of"nature and human in the same rhythm"and"the same treatment for common diseases",targeting the above pathogenesis,the method of"brain-eye synchronization"was proposed to restore the homeostasis of the brain and eyes to prevent and control myopia in children and adolescents,and the treatment rules were to regulate the rhythms of the time,harmonize the qi and blood,nourish the blood to soften the tendons,and replenish the essence and blood,so as to achieve the effect of brain-eye synchronization and the treatment of the spirit and the body together.This article summarized the theoretical basis of"brain-eye synchronization"and its clinical application in traditional Chinese and Western medicine,with a view to providing new ideas for the prevention and control of myopia in children and adolescents.

Traditional Chinese medicine upholds the unity of nature and humanity as its fundamental principle,asserting that man is in harmony with heaven and earth and corresponds to the sun and moon.Human life processes align with the circadian rhythms of nature,exhibiting periodic temporal changes-concepts that Western medicine defines as biological rhythms.The"opening-closing-pivot"of the three yin and three yang meridians represents the primary mode of interaction between nature and humanity.This mechanism regulates the transformation of yin and yang to qi within the body,ensuring synchronization with the circadian rhythm.Building upon this foundation,the concept of"the harmony of rhythms and states"was proposed to explain human growth and aging."Rhythms"encompass not only circadian cycles but also the movement of qi and blood,as well as the contraction rhythm of muscle fascia,among other physiological processes."States"refer to the dynamic evolution and transformation of qi during the"opening-closing-pivot"stages in both time and space."Harmony"pertains not only to the individual physiological balance of"rhythms"or"states"but also to their coherent interaction.The fundamental cause of myopia is"the disharmony of rhythms and states",considering that rhythm disorders,qi and blood disorders,and fascia imbalances contribute to this disease.Based on this understanding,myopia prevention and treatment should center on"regulating rhythms and states",with adjusting the pivot to brighten the eyes as the core therapeutic principle throughout the entire cycle of myopia.Treatment should be tailored to different disease stages and supplemented with methods such as time-based regulation,qi and blood harmonization,tendon relaxation and collateral dredging,and essence and blood nourishment to prevent and manage myopia effectively.

Cholesterol is a crucial lipid in the human body.Elevated levels of cholesterol can result in condi-tions such as hypercholesterolemia.3-hydroxy-3-methylglutaryl coenzyme A reductase(HMGCR)serves as a pivotal en-zyme in the synthesis of cholesterol,acting as a rate-limiting factor.As a result,HMGCR plays a critical role in maintain-ing cholesterol balance,with the regulatory processes being intricate in vivo.This review outlines the advancements in un-derstanding the regulatory mechanisms of HMGCR,encompassing transcriptional control,degradation pathways,and en-zyme activity.

Objective:To explore the relationship between mindfulness, optimism, and subjective well-being in post-lung transplantation patients, so as to provide a basis for nursing staff to improve patients' subjective well-being.Methods:This study was a cross-sectional survey. Convenience sampling was used to select 205 post-lung transplantation patients admitted to the First Affiliated Hospital of Guangzhou Medical University from October 2022 to November 2023 for the study. General Information Questionnaire, World Health Organization-Five Well-Being Scale, Mindful Attention Awareness Scale (MAAS) and Life Orientation Test-R (LOT-R) were used to investigate the study participants. Pearson correlation was used to analyze the correlation between subjective well-being and mindfulness and optimism in patients after lung transplantation. AMOS 24.0 software was used to construct a mediating model to analyze the path relationship between mindfulness, optimism and subjective well-being.Results:A total of 205 questionnaires were distributed and 202 valid questionnaires were recovered, with an effective recovery rate of 98.54% (202/205). In 202 patients after lung transplantation, the WHO-5 Well-Being Scale total score, MAAS total score, and LOT-R score were (16.31±4.73), (56.75±9.44), and (18.49±3.85), respectively. Lung transplantation patients' subjective well-being was positively correlated with mindfulness and optimism ( r=0.570, 0.600, both P<0.01). Optimism partially mediated the relationship between mindfulness and subjective well-being, with an effect value of 0.290 and an effect proportion of 52.35% (0.290/0.554) . Conclusions:Mindfulness and optimism are both positively correlated with subjective well-being in post-lung transplantation patients, and mindfulness could also influence subjective well-being through the mediating effect of optimism. Healthcare professionals should fully explore and cultivate positive psychological resources, such as mindfulness, in lung transplant patients, by increasing optimism as the target of intervention, which in turn improves patients' subjective well-being.
