ObjectiveBy comparing the composition and content of volatile components in raw products, wine-washed products and wine-fried products of Ligusticum sinense cv. Chaxiong rhizome(LSCR), to investigate the influence of wine processing on the volatile components of LSCR, in order to provide a basis for the development of quality standards for LSCR and its processed products. MethodsElectronic nose was used to identify the odors of LSCR, wine-washed and wine-fried LSCR, and their volatile components were detected by headspace gas chromatography-mass spectrometry(HS-GC-MS), and the relative mass fractions of these components were determined by peak area normalization method. Principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were performed on the obtained sample data by SIMCA 14.1 software, and the differential components of LSCR, wine-washed and wine-fried LSCR were screened according to the variable importance in the projection(VIP) value>1. Pearson correlation analysis was used to explore the relationship between volatile differential flavor components and electronic nose sensors. ResultsElectronic nose detection results showed that there were significant differences in the odors of LSCR, wine-washed and wine-fried LSCR, mainly reflected in the sensors S2, S4, S5, S6, S11, S12, S13. And a total of 62 compounds were identified from LSCR and its wine-processed products, among which 46, 50 and 51 compounds were identified from LSCR, wine-fried and wine-washed LSCR, respectively. There were 21 differential components between the raw products and wine-fried products, of which 10 components were increased and 11 were decreased after processing. There were 20 differential components between the raw products and wine-washed products, of which 11 constituents increased and 9 decreased after processing. There were 17 differential components between the wine-wash products and wine-fried products. Compared with the wine-washed products, the contents of 13 components in the wine-fried products increased, and the contents of 4 components decreased. The increasing trend of the content of phthalides in the wine-washed products was more obvious than that in the wine-fried products, but the content of total volatile components was higher in the wine-fried products than the wine-washed products. Correlation analysis showed that there were different degrees of correlation between the 7 differential sensors of electronic nose and 24 differential volatile components, mainly phthalides and olefins. ConclusionThe odor and the content of volatile components in LSCR changed obviously after wine processing, and n-butylphthalide, Z-butylidenephthalide and E-ligustilide can be used as the candidate differential markers of volatile components in LSCR before and after wine processing.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most prevalent cause of chronic liver disease worldwide, and its intricate pathogenesis presents challenges in the development of new drugs. As a common way of post-translational modification, acetylation regulates protein stability, enzyme activity, and subcellular localization, occurring extensively in MASLD-associated processes such as lipid metabolism, inflammatory response, and oxidative stress. In this paper, we comprehensively review the mechanism of acetylation in MASLD, analyze the expression levels of acetylases in liver tissues of MASLD patients from the gene expression omnibus (GEO), discuss the changes in relevant enzyme expression and mechanisms in animal models, and further explore the feasibility of targeting acetylation for MASLD treatment, in the hope of offering a new perspective for advancing drug discovery in the field of MASLD.

OBJECTIVE To investigate the improvement effects of 3,5,6,7,8,3′,4′-heptamethoxyflavone (HMF) of Fructus Aurantii on rats with damp blockage of the middle energizer. METHODS The rats were randomly divided into normal group, model group, positive control group (Raceanisodamine tablet, 1 mg/kg), HMF low-dose, medium-dose and high-dose groups (0.3, 0.6, 0.9 mg/kg), with 7 rats in each group. Except for the normal group, the other groups were modeled by internal and external composite factors. After successful modeling, the rats in each group were given the corresponding drug or normal saline, once a day, for 14 days. The general behavioral states such as dietary intake, water intake and mental state of the rats were observed, and the fecal water content rate and saliva flow rate were measured. Hematoxylin-eosin (HE) staining was used to observe the pathological and morphology in gastric and small intestinal tissues of rats. The plasma content of aldosterone was detected, and the expression of aquaporins (AQP3) in the gastric tissue of rats was determined. RESULTS Compared with the normal group, the dietary intake and water intake of the model group rats were significantly decreased (P<0.01), the fecal water content rate, salivary flow rate, plasma content of aldosterone and the expression of AQP3 in gastric tissue were increased significantly (P<0.01). Gastric tissue injury invaded the mucosal muscle layer, resulting in mucosal muscle layer rupture; pathological and morphological changes such as small intestinal villous erosion and glandular structure destruction were observed in the small intestine. Compared with the model group, the dietary intake and water intake of rats were increased in HMF groups; fecal water content rate, salivary flow rate, plasma content of aldosterone, the expression of AQP3 in gastric tissue were decreased, most of the above differences were statistically significant (P<0.05 or P<0.01). The pathological and morphological changes in the gastric and small intestine tissues of rats had been improved to varying degrees. CONCLUSIONS HMF of Fructus Aurantii with dry property HMF could improve the symptoms of rats with damp blockage of middle energizer, the mechanism of which may be associated with reducing the content of plasma aldosterone and down-regulating the expression of gastric AQP3.

ObjectiveTo investigate the effect of linalool against acute liver injury induced by aflatoxin B1(AFB1) in rats and explore its protective mechanism. MethodTwenty male SPF SD rats were randomly divided into three groups: Control (n=6), AFB1 (n=7), and linalool (n=7) groups. Linalool solution (200 mg·kg-1) was administered preventatively for 14 days, while the control and AFB1 groups intragastrically received an equivalent volume of double distilled water. After preventative administration of linalool, AFB1 solution (1 mg·kg-1, dissolved in saline) was intraperitoneally injected for two consecutive days to induce acute liver injury in rats. Samples were collected and processed 14 days after model establishment. Pathological changes in liver tissue of rats were observed using Hematoxylin-eosin(HE) staining and Masson staining. Biochemical detection was performed to measure the levels of alanine transaminase(ALT), aspartate transaminase(AST), γ-glutamyl transferase(GGT), lactate dehydrogenase(LDH), alkaline phosphatase(ALP), total bilirubin(TBil), direct bilirubin(DBil), indirect bilirubin(IBil), malondialdehyde(MDA), superoxidedismutase(SOD), catalase(CAT) , glutathione(GSH), Fe3+, and Fe2+ in the liver tissue. Western blot was adopted to assess protein expression levels of nuclear factor-erythroid 2-related factor 2(Nrf2) and heme oxygenase-1(HO-1). Molecular docking was performed to verify the binding between linalool and key proteins of the Nrf2/HO-1 signaling pathway. Molecular dynamics techniques were used to confirm the stability and affinity of linalool binding with key proteins of the Nrf2/HO-1 signaling pathway. ResultPathological results showed that compared to that in the AFB1 group, the liver structure in the linalool group tended to be normal, with a significant decrease in blue collagen fibers. The linalool group exhibited significantly reduced levels of ALT, AST, GGT, LDH, ALP, TBil, DBil, and IBil (P<0.01), Fe3+ and Fe2+ content, and oxidative stress marker MDA (P<0.01). The levels of antioxidants SOD, CAT, and GSH significantly increased (P<0.01). Molecular docking showed a molecular docking energy between linalool and Nrf2 and HO-1 targets of -5.495 6 and -5.199 4 kcal·mol-1(1 cal≈4.186 J), respectively. Molecular dynamics results indicated strong affinity in the binding of linalool with Nrf2 and HO-1. Western blot revealed a significant increase in Nrf2 protein expression (P<0.05) and a decrease in HO-1 protein expression (P<0.01) in the linalool group. ConclusionLinalool may protect against AFB1-induced acute liver injury by modulating the Nrf2/HO-1 ferroptosis signaling pathway to inhibit liver cell ferroptosis and regulate hepatic oxidative stress levels.

ObjectiveMetabolomics was utilized to investigate the preventive effect of notoginseng total saponins(NTS) on aspirin(acetyl salicylic acid, ASA)-induced small bowel injury in rats. MethodFifty male SD rats were randomly divided into normal and model groups, NTS high-dose and low-dose groups(62.5, 31.25 mg·kg-1), and positive drug group(omeprazole 2.08 mg·kg-1+rebamipide 31.25 mg·kg-1), with 10 rats in each group. Except for the normal group, rats in other groups were given ASA enteric-coated pellets 10.41 mg·kg-1 daily to establish a small intestine injury model. On this basis, each medication group was gavaged daily with the corresponding dose of drug, and the normal group and the model group were gavaged with an equal amount of drinking water. Changes in body mass and fecal characteristics of rats were recorded and scored during the period. After 14 weeks of administration, small intestinal tissues of each group were taken for hematoxylin-eosin(HE) staining, scanning electron microscopy to observe the damage, and the apparent damage of small intestine was scored. Serum from rats in the normal group, the model group, and the NTS high-dose group was taken and analyzed for metabolomics by ultra-performance liquid chromatography-quadrupole-electrostatic field orbitrap high-resolution mass spectrometry(UPLC-Q-Exactive Orbitrap MS), and the data were processed by multivariate statistical analysis, the potential biomarkers were screened by variable importance in the projection(VIP) value≥1.0, fold change(FC)≥1.5 or ≤0.6 and t-test P<0.05, and pathway enrichment analysis of differential metabolites was performed in conjunction with Human Metabolome Database(HMDB) and Kyoto Encyclopedia of Genes and Genomes(KEGG). ResultAfter 14 weeks of administration, the average body mass gain of the model group was lower than that of the normal group, and the NTS high-dose group was close to that of the normal group. Compared with the normal group, the fecal character score of rats in the model group was significantly increased(P<0.05), and compared with the model group, the scores of the positive drug group and the NTS high-dose group were reduced, but the difference was not statistically significant. HE staining and scanning electron microscopy results showed that NTS could significantly improve ASA-induced small intestinal injury, compared with the normal group, the small bowel injury score of the model group was significantly increased(P<0.01), compared with the model group, the small bowel injury scores of the NTS low and high dose groups were significantly reduced(P<0.05, P<0.01). Serum metabolomics screened a total of 75 differential metabolites between the normal group and the model group, of which 55 were up-regulated and 20 were down-regulated, 76 differential metabolites between the model group and the NTS groups, of which 14 were up-regulated and 62 were down-regulated. NTS could modulate three differential metabolites(salicylic acid, 3-hydroxybenzoic acid and 4-hydroxybenzoic acid), which were involved in 3 metabolic pathways, namely, the bile secretion, the biosynthesis of folic acid, and the biosynthesis of phenylalanine, tyrosine and tryptophan. ConclusionNTS can prevent ASA-induced small bowel injury, and the underlying mechanism may be related to the regulation of bile secretion and amino acid metabolic pathways in rats.

Objective:To investigate the clinical efficacy of single-port and mini-three-port laparoscopic sleeve gastrectomy (MTP-SG) for obesity.Methods:The propensity score matching and retrospective cohort study was conducted. The clinical data of 364 obesity patients in the Chinese Obesity and Metabolic Surgery Database who were admitted to The First Affiliated Hospital of Jinan University from July 2016 to December 2023 were collected. There were 79 males and 285 females, aged (31±9)years. Of 364 patients, 67 cases undergoing single-port laparoscopic sleeve gastrectomy (SP-SG) were divided into the SP group, and 297 cases undergoing MTP-SG were divided into the MTP group. Propensity score matching was done by the 1∶1 nearest neighbor matching method. The clamp value was set as 0.1. Measurement data with normal distribution were expressed as Mean± SD, and t test was used for comparison between groups. Measurement data with skewed distribution were expressed as M( Q1, Q1), and the rank sum test was used for comparison between groups. Count data were expressed as absolute numbers, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Results:(1) Propensity score matching and comparison of general data of patients between the two groups after matching. Of 364 patients, 126 cases were successfully matched, including 63 cases in the SP group and 63 cases in the MTP group. After propensity score matching, the confounding bias of gender, body mass, body mass index (BMI), waist circumference, waist hip ratio were eliminated between the two groups. (2) Intraoperative and post-operative conditions. Both groups of patients successfully completed laparoscopic sleeve gastrectomy. After propensity score matching, the operation time, volume of intraoperative blood loss, number of postoperative painkillers used, number of postoperative antiemetics used, duration of postoperative hospital stay, duration of total hospital stay, surgical cost, and total hospitalization cost of the 63 pati-ents in SP group were 101(90,120)minutes, 10(10,10)mL, 1.0(1.0,2.5)times, 3.0(1.0,5.0)times, 4(3,5)days, 7(5,8)days, 4.1(3.5,4.3) ten thousand yuan, and (6.4±0.8) ten thousand yuan, respectively. The above indicators of the 27 patients in MTP group were 100(90,120)minutes, 10(10,15)mL, 2.0(1.0,4.0)times, 4.0(3.0,5.0)times, 3(3,4)days, 5(5,6)days, 3.2(2.8,4.2) ten thousand yuan, and (5.8±0.8) ten thousand yuan, respectively. There were significant differences in number of postoperative antiemetics used, duration of postoperative hospital stay, duration of total hospital stay and total hospitalization cost between the two groups ( Z=-2.39, -3.93, -3.03, t=4.04, P<0.05), and there was no significant difference in operation time, volume of intraoperative blood loss, number of post-operative painkillers used and surgical cost between the two groups ( Z=-0.49, -1.00, -1.23, -1.47, P>0.05). (3) Follow-up. One hundred and ninety five of the 364 patients conducted postoperative 1 month follow-up, including 25 patients in the SP group and 170 patients in the MTP group, and no patient experienced complications such as gastric leakage, infection, or incisional hernia. Both groups of patients had good surgical incisions. After propensity score matching, the change in BMI (ΔBMI), percentage of total weight loss (%TWL), and percentage of excess weight loss (%EWL) of 24 patients in the SP group were (3.7±1.4)kg/m 2, 11.0%±3.0%, 52.6%±30.0%, respectively. The above indicators of 40 patients in the MTP group were (4.1±1.3)kg/m 2, 11.1%±2.8%, 41.8%±19.1%, respectively. Patients who conducted the postoperative 12 month follow-up were 21 and 131 in the SP group and the MTP group, respectively. After propensity score matching, the ΔBMI, %TWL and %EWL of 15 patients in the SP group were (8.7±4.1)kg/m 2, 26.2%±9.8%, 130.0%±45.1%, respectively. The above indicators of 36 patients in the MTP group were (9.8±4.0)kg/m 2, 27.2%± 8.7%, 107.1%±40.7%, respectively. Conclusion:Both SP-SG and MTP-SG can be used to treat obesity patients and achieve satisfactory short-term results.

There is increasing evidence that the activation of glucagon-like peptide-1 receptor(GLP-1R)can be used as a therapeutic intervention for cognitive disorders.Here,we have screened GLP-1 R targeted com-pounds from Scutellaria baicalensis,which revealed baicalein is a potential GLP-1 R small-molecule agonist.Mitophagy,a selective autophagy pathway for mitochondrial quality control,plays a neuro-protective role in multiple cognitive impairment diseases.We noticed that Glp1r knock-out(KO)mice present cognitive impairment symptoms and appear worse in spatial learning memory and learning capacity in Morris water maze(MWM)test than their wide-type(WT)counterparts.Our mechanistic studies revealed that mitophagy is impaired in hippocampus tissue of diabetic mice and Glp1r KO mice.Finally,we verified that the cognitive improvement effects of baicalein on diabetic cognitive dysfunction occur through the enhancement of mitophagy in a GLP-1 R-dependent manner.Our findings shed light on the importance of GLP-1 R for cognitive function maintenance,and revealed the vital significance of GLP-1R for maintaining mitochondrial homeostasis.Furthermore,we identified the therapeutic potential of baicalein in the treatment of cognitive disorder associated with diabetes.
