Metabolic dysfunction-associated steatotic liver disease(MASLD)has become the most prevalent chronic liver disease worldwide,and China is facing a severe challenge of rapidly increasing MASLD burden.Beverages,as an important modifiable factor,have become a research focus for primary prevention and lifestyle management of MASLD.This article reviews beverage consumption trends,provides an in-depth analysis of the mechanisms and health effects of sugar-sweetened beverages,alcoholic drinks,coffee,and tea on MASLD,summarizes their potential pathogenic and protective pathways,and explores comprehensive strategies including beverage intervention,lifestyle coordination,functional beverage development,psychological and behavioral mechanism regulation,and targeted population prevention.The aim is to provide theoretical basis and practical guidance for the localized and precise prevention and control of MASLD.

Objective:Taking emergency department (ED) as a starting point, to analyze the epidemiological characteristics and mortality risk factors of sepsis, and to provide evidences for ED to carry out the strategy of "three early and two lower" for sepsis.Methods:Based on the ED and inpatient medical record management information platform of Tianjin Medical University Gernal Hospital, adult ED patients with sepsis from January 1, 2017 to December 31, 2020 were included according to the third international consensus definitions for sepsis and septic shock in 2016 and the consensus of Chinese experts on early prevention and blocking of sepsis in 2020. The epidemiological characteristics of patients were retrospectively analyzed. Chi-square test was used to compare the difference of age, sex, hospitalization times, length of stay, hospitalization cost and infection location between dead patients and survival patients, and a stepwise logistic regression model was used to analyze the influencing factors of mortality in hospitalized patients with ED sepsis.Results:A total of 7 494 patients with sepsis in ED were included in this study, and the annual and monthly component ratios varied from 3.8‰ to 6.1‰ and 2.0‰ to 9.0‰, respectively. The main characteristics of patients with sepsis in ED were as follows: 40-69 years old (46.0%), male (59.0%), mostly diagnosed with sepsis (96.8%), mainly treated with urban health insurance (59.6%), and ED diagnosis and treatment fees of 2 000-8 000 Yuan (51.1%). The mortality of hospitalized patients with ED sepsis was 24.4% and that of hospitalized patients with septic shock was 28.8%. The main characteristics of hospitalized patients with ED sepsis were as follows: most of them were male (56.2%) patients over 70 years old (56.0%), most of them were diagnosed with sepsis (94.0%) and hospitalized for the first time (76.0%), the median hospitalization time was 15 d, most of them were hospitalized under urban health insurance (65.2%), and the median hospitalization fees was 47 000 Yuan. The risk factors of death were influenced by age and length of stay. Patients aged 70 years or older had a higher risk of death than those aged from 18 to 39 years, and patients with a length of stay of more than 7 d had a lower risk of death than those with a length of stay of shorter than 7 d. The primary infection focus were mainly respiratory and urinary systems, while the death rate of patients with hematological and abdominal infections was relatively high, and the difference was statistically significant ( P<0.01). Respiratory and abdominal infections were risk factors for death in patients with ED sepsis. Conclusions:The composition ratio of sepsis in ED patients is not regular in time, so vigilance of sepsis in elderly men and patients with respiratory system, blood system, urinary system and abdominal infections should be constantly raised. Patients with sepsis who are older, hospitalized more frequently, hospitalized for a shorter time, and infected in the respiratory system or abdomen have a higher risk of death.

OBJECTIVETo investigate the effects of β-elemene in suppressing the proliferation and apoptosis of SGC7901 gastric cancer cells in vitro and explore the underlying mechanisms.

METHODSUsing MTT assay, flow cytometry, and clonogenic survival assay, we assessed the effects of β-elemene on the viability, apoptosis, cell cycle distribution, and clonogenic survival of gastric cancer SGC7901 cells and gastric mucosal epithelial GES-1 cells. Western blotting was employed to determine the changes in the protein expression profiles in SGC7901 cells in response to β-elemene treatment.

RESULTSβ-elemene significantly suppressed the cell viability and increased the apoptosis of SGC7901 cells, and these effects were less obvious in GES-1 cells. β-elemene decreased clonogenic survival of SGC7901 cells, increased the proportion of G2/M phase cells, decreased the expression of Bcl-2, and increased the expression of Bax and cleaved caspase-3. β-elemene did not obviously affect the expression of total p21-activated protein kinase 1 (Pak1) but decreased the level of phospho-Pak1 (Thr423) and phospho-ERK1/2 (Thr202/Tyr204) in SGC7901 cells.

CONCLUSIONβ-elemene inhibits the proliferation and induces apoptosis of gastric cancer cells possibly by inhibiting Pak1/ERK signaling and regulating apoptosis-associated proteins such as Bcl-2 and Bax.

OBJECTIVETo observe the effects of Fructus Corni polysaccharides (FCP) on sexual function of hemicastrated rats.

METHOD70 male SD rats are randomly divided into 7 groups with their right testis extirpated except for normal control group. Normal control group and negative control group are given saline (ig) while positive control group are injected hypodermically testosterone propionate at dose of 2 mg x kg(-1) x d(-1). FCP control groups are given FCP separately at dose of 10, 50, 100, 150 mg x kg(-1) x d(-1) (ig). Mating test and erective test are observed. The levels of serum sex hormone T, LSH, FSH, E2 are detected with the Radioimmunoassay (RIA).

RESULTIncubation period of penis erection and mounting are shortened in FCP control groups and positive control group, and the percentage of mounting rats is increased. The level of serum sex hormone T is increased, but estradiol level is reduced. The organ coefficient of foreskin gland and seminal vesicle-prostate gland as well as sperm count and vigor are increased significantly (P < 0.01 or P < 0.05).

CONCLUSIONFCP can increase the sexual function of hemicastrated rats. The mechanism is probably through adjustment of the hypothalamus-pituitary-gonadal axis.
