OBJECTIVE To study the effects of enteral immune microecological nutrition combined with ω-3 fish oil fat emulsion on postoperative recovery， immune function， liver function and inflammation level in patients with hepatocellular carcinoma resection， as well as the safety of the medication. METHODS A total of 106 patients with hepatocellular carcinoma admitted to our Hospital from June 2020 to December 2023 were selected and divided into control group and study group according to the random number table method， with 53 cases in each group. After undergoing hepatocellular carcinoma resection， control group was given Intacted protein enteral nutrition solution+Enhanced enteral immune microecological nutrition， and the study group was given ω-3 fish oil fat emulsion injection based on the control group. The clinical indicators （postoperative exhaust time， defecation time， postoperative ambulation， and hospital stay）， liver function indicators [alanine transaminase （ALT）， lactate dehydrogenase （LDH）， aspartate transaminase （AST）]， immune function indexes （CD3+ ， CD4+ ， CD8+ ， CD4+/CD8+）， inflammatory factor indexes [tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， IL-6， IL-8]， and indicators of intestinal mucosal barrier [D-lactic acid， intestinal fatty acid binding protein （I-FABP）] were compared between 2 groups， and the occurrence of ADR was recorded. RESULTS Compared with the control group， the postoperative exhaust time， postoperative defecation time， and hospital stay of the study group were shortened significantly， and postoperative ambulation increased significantly （P＜0.05）. After treatment， ALT， LDH， AST， CD8+， inflammatory factors， D-lactic acid and I-FABP of 2 groups were significantly lower than before treatment， and the study group was significantly lower than the control group （P＜0.05）； CD4+， CD3+， and CD4+/CD8+ of two groups were significantly higher than before treatment， and the study group was significantly higher than the control group （P＜0.05）. There was no significant difference in the incidence of ADR between 2 groups （P＞0.05）. CONCLUSIONS Enteral immune microecological nutrition combined with ω-3 fish oil fat emulsion injection can shorten the recovery time of patients after hepatocellular carcinoma resection， improve immune function， reduce inflammatory response， and improve liver function with good safety.

Myocardial fibrosis is a serious cause of heart failure and even sudden cardiac death. However, the mechanisms underlying myocardial ischemia-induced cardiac fibrosis remain unclear. Here, we identified that the expression of sterile alpha and TIR motif containing 1 (SARM1), was increased significantly in the ischemic cardiomyopathy patients, dilated cardiomyopathy patients (GSE116250) and fibrotic heart tissues of mice. Additionally, inhibition or knockdown of SARM1 can improve myocardial fibrosis and cardiac function of myocardial infarction (MI) mice. Moreover, SARM1 fibroblasts-specific knock-in mice had increased deposition of extracellular matrix and impaired cardiac function. Mechanically, elevated expression of SARM1 promotes the deposition of extracellular matrix by directly modulating P4HA1. Notably, by using the Click-iT reaction, we identified that the increased expression of ZDHHC17 promotes the palmitoylation levels of SARM1, thereby accelerating the fibrosis process. Based on the fibrosis-promoting effect of SARM1, we screened several drugs with anti-myocardial fibrosis activity. In conclusion, we have unveiled that palmitoylated SARM1 targeting P4HA1 promotes collagen deposition and myocardial fibrosis. Inhibition of SARM1 is a potential strategy for the treatment of myocardial fibrosis. The sites where SARM1 interacts with P4HA1 and the palmitoylation modification sites of SARM1 may be the active targets for anti-fibrosis drugs.

Osteoporosis is a prevalent skeletal condition characterized by reduced bone mass and strength, leading to increased fragility. Buqi-Tongluo (BQTL) decoction, a traditional Chinese medicine (TCM) prescription, has yet to be fully evaluated for its potential in treating bone diseases such as osteoporosis. To investigate the mechanism by which BQTL decoction inhibits osteoclast differentiation in vitro and validate these findings through in vivo experiments. We employed MTS assays to assess the potential proliferative or toxic effects of BQTL on bone marrow macrophages (BMMs) at various concentrations. TRAcP experiments were conducted to examine BQTL's impact on osteoclast differentiation. RT-PCR and Western blot analyses were utilized to evaluate the relative expression levels of osteoclast-specific genes and proteins under BQTL stimulation. Finally, in vivo experiments were performed using an osteoporosis model to further validate the in vitro findings. This study revealed that BQTL suppressed receptor activator of NF-κB ligand (RANKL)-induced osteoclastogenesis and osteoclast resorption activity in vitro in a dose-dependent manner without observable cytotoxicity. The inhibitory effects of BQTL on osteoclast formation and function were attributed to the downregulation of NFATc1 and c-fos activity, primarily through attenuation of the MAPK, NF-κB, and Calcineurin signaling pathways. BQTL's inhibitory capacity was further examined in vivo using an ovariectomized (OVX) rat model, demonstrating a strong protective effect against bone loss. BQTL may serve as an effective therapeutic TCM for the treatment of postmenopausal osteoporosis and the alleviation of bone loss induced by estrogen deficiency and related conditions.

Objective To investigate the relationship between vertebrobasilar artery tortuosity and vasogenic dizziness/vertigo-related cerebral infarction in the elderly.Methods A total of 160 elderly patients with vasogenic dizziness/vertigo-related cerebral infarction admitted to the Department of Neurology of Taiyuan Xishan Hospital from January 2022 to October 2023 were selected.The patients were divided into tortuous group and non-tortuous group,80 cases in each group,according to the presence of vertebrobasilar artery abnormality by magnetic resonance angiography.The general clinical data,vascular disease risk factors,and the expanded-National Institutes of Health stroke scale(e-NIHSS)score of two groups were compared.The tortuous group was divided into simple abnormality group and mixed abnormality group according to vertebrobasilar artery morphology,and the degree of influence on related cerebral infarction was analyzed.Results The proportion of hypertension,vertebral artery dominance,smoking history and e-NIHSS score in ortuous group were significantly higher than those in non-tortuous group(P＜0.05).Multivariate Logistic regression analysis showed that history of hypertension,vertebral artery dominance,and smoking history were independent risk factors for elderly patients with vasogenic dizziness/vertigo-related cerebral infarction with vertebrobasilar artery abnormality(P＜0.05).54.3％of patients in simple abnormality group were moderate to severe stroke patients,and 58.8％of patients in mixed abnormality group were moderate to severe stroke patients,and there was no statistical significance between two groups(x2=0.029,P=0.864).Conclusion History of hypertension,vertebral artery dominance,and smoking history were independent risk factors for vasogenic dizziness/vertigo-related cerebral infarction in elderly patients with vertebrobasilar artery tortuosity,and these patients had higher neurological deficit scores.

Background/Aims: The shortage of donor liver hinders the development of liver transplantation. This study aimed to clarify the poor outcomes of functionally marginal liver grafts (FMLs) and provide evidence for the improvement of ischemia-free liver transplantation (IFLT) after FML transplantation. Methods: Propensity score matching was used to control for confounding factors. The outcomes of the control group and FML group were compared to demonstrate the negative impact of FMLs on liver transplantation patients. We compared the clinical improvements of the different surgical types. To elucidate the underlying mechanism, we conducted bioinformatic analysis based on transcriptome and single-cell profiles. Results: FMLs had a significantly greater hazard ratio (HR: 1.969, P=0.018) than did other marginal livers. A worse 90-day survival (Mortality: 12.3% vs. 5.0%, P=0.007) was observed in patients who underwent FML transplantation. Patients who received FMLs had a significant improvement in overall survival after IFLT (Mortality: 10.4% vs 31.3%, P=0.006). Pyroptosis and inflammation were inhibited in patients who underwent IFLT. The infiltration of natural killer cells was lower in liver grafts from these patients. Bulk transcriptome profiles revealed a positive relationship between IL-32 and Caspase 1 (R=0.73, P=0.01) and between IL-32 and Gasdermin D (R=0.84, P=0.0012). Conclusions FML is a more important negative prognostic parameter than other marginal liver parameters. IFLT might ameliorate liver injury in FMLs by inhibiting the infiltration of NK cells, consequently leading to the abortion of IL-32, which drives pyroptosis in monocytes and macrophages.

Objective:To analyze the influencing factors of the public hospital′s WeChat official accountcommunication effect, for references for improving the public hospital′s WeChat official account′s public opinion guidance in health dissemination field.Methods:The communication data of all the tweets on the official account of a tertiary hospital from 2018 to 2021 were obtained, taking the tweets reading times as the evaluation index of the communication effect of the WeChat official account. The number of sharing times, the number of title words, punctuation points, the first launch platform and content type were took as factors that may affect comounication effectiveness for single factor analysis and multiple linear regression analysis.Results:A total of 1 102 tweets were included, with an average reading times of 10 670, and an average sharing times of 411. The top 10 tweets in terms of reading times were mainly about the treatment of major diseases, emergencies, common misconceptions and health popular science. The sharing times and the hand-painted entries were positively correlated with the reading times( P<0.05), while the number of title words and punctuation was negatively correlated with the reading times( P<0.05). The reading times of tweets varied with different title sentence structures, initial platforms, source departments, and content types, and the differenceswere statistically significant( P<0.05). The sharing times, hand-painted entries, title sentence structures and content typeswere the influencing factors of the public hospital′s WeChat official account communication effect( P<0.05). Conclusions:The tweets of a public hospital′s WeChat official account with high reading times focused on the hot issues that people pay attention to, and there were many factors influencing the communication effect. The author suggested that the WeChat official account of public hospitals should focus on the needs of the people, promote the construction of high-quality content, and further strengthen the design level of copywriting to improve its audience and communication power.
