    Objective: To investigate the protective effect of ursolic acid (UA) on alcoholic liver damage (ALD) mice by observing the expression of bile salt export pump (BSEP) and sodium taurocholate cotransporting polypeptide (NTCP) in mice after UA intervention. Methods: Eighteen 10-week-old SPF C57BL/6J mice were randomly divided into three groups (normal control group, alcohol model group, and UA+alcohol group). The mice were treated with intragastric administration for 7 weeks. The changes of body weight were recorded. The pathological changes of liver tissue were observed by HE staining. The serum total bile acid (TBA), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were detected by microplate method. The expression of BSEP and NTCP protein in liver tissue was detected by Western blotting. Results: The average body weight of mice in the alcohol group was significantly lower than that in the normal control group (P＜0.05). The structure of hepatic lobules in the normal control group was intact and there was no inflammatory cell infiltration, while the structure of hepatic lobules in the alcohol model group was blurred, accompanied by obvious steatosis, and the NAS score was significantly increased (P＜0.05). Compared with the alcohol model group, after UA intervention, the damage of hepatic lobule structure in mice was improved, the number of fat vacuoles and inflammatory cells in hepatocytes was reduced, and the NAS score was significantly reduced (P＜0.05). In addition, compared with the normal control group, the liver index of the alcohol model group was significantly increased (P＜0.05), while the liver index of the UA+alcohol group was significantly lower than that of the alcohol model group (P＜0.05). At the same time, after UA intervention, the increase of TBA, AST and ALT induced by alcohol intake was significantly inhibited (P＜0.05). The results of Western blotting showed that compared with the normal control group, the expression levels of BSEP and NTCP in the liver tissue of the alcohol model group were significantly decreased (P＜0.05). After UA intervention, the expression levels of transporter BSEP and NTCP protein in UA+alcohol group were significantly increased (P＜0.05). Conclusion: UA supplementation can significantly improve liver damage caused by alcohol, and the mechanism may be related to the up-regulation of BSEP and NTCP protein expression, thereby regulating bile acid homeostasis.

    Objective: To explore the effect of glycopyrronium bromide on lung ischemia-reperfusion injury (LIRI) in rats, and to analyze the mechanism of HMGB1/TLR4/NF-κB signaling pathway in this process, so as to provide theoretical basis for clinical application. Methods: Thirty-two 6-week-old male SD rats were randomly divided into 4 different groups, with 8 rats in each group. Four groups were: sham operation group (Sham), ischemia reperfusion injury model group (I/R), low dose group (L) and high dose group (H). The pathological changes of lung tissue were observed and evaluated by HE staining. The ratio of wet weight to dry weight (W/D) was measured to determine the water content of lung tissue. The levels of indicators related to oxidative stress in lung tissue were detected. At the same time, the expression of HMGB1, TLR4 and p-NF-κB protein in lung tissue was analyzed by Western blotting, and the expression levels of HMGB1, TLR4 and NF-κB mRNA were detected by RT-qPCR. Results: Pathological findings showed that the lung tissue structure of the Sham group was clear and no damage was observed; while in the I/R group, pulmonary capillary congestion, interstitial edema, alveolar wall thickening, severe lung tissue damage, and a large number of inflammatory cell infiltration were observed. The above conditions in group L and group H were less than those in the I/R group, and H group was lighter. Compared with Sham group, the W/D ratio and the expression levels of HMGB1, TLR4 and NF-κB mRNA in the I/R group and L group were increased. However, compared with the I/R group, the performance of the above indicators in the L group and H group decreased, and the data in the H group were lower, the differences were statistically significant (P＜0.05). Further analysis showed that compared with Sham group, the concentration of malondialdehyde (MDA), the expression of HMGB1, TLR4 and p-NF-κB protein in the I/R group, L group and H group increased, while the activity of superoxide dismutase (SOD) decreased. Compared with the I/R group, the expression of the above indicators in the L group and H group decreased, while the SOD activity increased, and the performance of the H group was more obvious, the differences were statistically significant (P＜0.05). Conclusion: Glycopyrronium bromide can reduce the inflammatory response and oxidative stress during LIRI by inhibiting the activation of HMGB1/TLR4/NF-κB signaling pathway, thereby improving LIRI in rats.

Methods: GEPIA database was used to analyze the expression of COL10A1 in breast cancer patients. The expression of COL10A1 in the serum of 30 breast cancer patients was detected by PCR, and its relationship with the clinical data of patients was analyzed. ROC curve was used to analyze the clinical diagnostic value of COL10A1 in breast cancer. The potential targets of COL10A1-mediated breast cancer were obtained through the Genecards database and OMIM database, and they were input into the STRING database to obtain the TSV file of the protein-protein interaction (PPI) network. GO enrichment analysis and KEGG enrichment analysis were used to explore different functional categories and related signal transduction pathways. Results: Bioinformatics analysis and PCR results showed that COL10A1 was highly expressed in breast cancer, which was closely related to histological grade, TNM stage, distant lymph node metastasis and Her2. ROC curve showed that the area under the curve of COL10A1 was 0.690 0 (95%CI: 0.5567-0.8233). When the optimal cut-off value was 1.1026, the sensitivity and specificity of COL10A1 in the diagnosis of breast cancer were 60.0% and 68.9%, respectively. A total of 14 potential targets of COL10A1-mediated breast cancer were obtained by combining the Genecards database with the OMIM database. A total of 241 GO terms were enriched by GO analysis, including 9 cellular components, 48 biological processes, and 12 molecular functions. KEGG enrichment analysis enriched a total of 12 signal transduction pathways. Conclusion: The high expression of serum COL10A1 in breast cancer patients is closely related to clinicopathological indicators, and has certain clinical value for breast cancer risk assessment.

    Objective: To analyze the correlation between the levels of serum transcription activator factor 3 (ATF3), tumor necrosis factor receptor 1 (TNFR1), angiopoietin-like protein 4 (ANGPTL4) and the renal function, prognosis of patients with diabetic nephropathy. Methods: A total of 152 patients with diabetic nephropathy who were treated in the Second People's Hospital of Jiaozuo City from April 2022 to January 2024 were selected as the study group, and 152 patients with simple diabetes who were treated in the same period were selected as the control group. The levels of serum ATF3, TNFR1, ANGPTL4 and renal function indexes such as serum calcium, serum phosphorus, serum creatinine and glomerular filtration rate (eGFR) were compared between the two groups at admission, and their correlation was analyzed. The levels of serum ATF3, TNFR1 and ANGPTL4 in patients with different prognosis were compared at admission, and their correlation with prognosis and predictive value for prognosis were analyzed by partial regression. Results: Compared with the control group, the levels of ATF3, TNFR1, and ANGPTL4 in the study group were significantly higher at admission (P＜0.05). The levels of blood calcium and creatinine in the study group were higher than those in the control group, while the levels of blood phosphorus and eGFR were lower than those in the control group (P＜0.05). Serum ATF3, ANGPTL4, and TNFR1 were negatively correlated with blood phosphorus and eGFR, and positively correlated with blood calcium and creatinine levels (P＜0.05). In the study group, patients with poor prognosis had higher levels of ATF3, ANGPTL4, and TNFR1 on admission than patients with good prognosis (P＜0.05). Logistic regression analysis showed that serum ATF3, ANGPTL4 and TNFR1 were risk factors for poor prognosis of patients (P＜0.05). The efficacy of combined prediction of serum ATF3, TNFR1 and ANGPTL4 levels on admission in predicting poor prognosis of patients was 0.807, which was higher than that of each index alone (P＜0.05). Conclusion: The increase in serum levels of ATF3, TNFR1, and ANGPTL4 in patients with diabetic nephropathy is associated with their renal function. Clinical detection of these levels can help predict the prognosis of patients and provide effective reference for clinical diagnosis and treatment.

Results: The total effective rate of clinical efficacy in the experimental group was higher than that in the control group (P＜0.05). There were no statistically significant differences in PaO2, PaCO2, and SaO2 levels between the two groups before treatment and at 12, 24, and 48 hours after treatment (P＞0.05). There was no significant difference in PaO2, PaCO2 and SaO2 levels between the two groups before treatment and 12,24 and 48 hours after treatment (P＞0.05). There was no difference in CRP and PCT levels between the two groups before treatment (P＞0.05). After 3 days of treatment, CRP and PCT in the experimental group were lower than those in the control group (P＜0.05). There was no significant difference in sputum traits between the two groups before treatment (P＞0.05). After 12, 24 and 48 hours of treatment, the sputum traits I of the experimental group were better than those of the control group (P＜0.05). The sequential treatment time and total hospitalization time of the experimental group were lower than those of the control group (P＜0.05). Conclusion: High-flow nasal cannula oxygen therapy can improve the clinical efficacy of patients with pneumonia complicated with type I respiratory failure after mechanical ventilation weaning, dilute sputum, improve oxygenation, reduce inflammation, improve patient tolerance, reduce the risk of re-intubation mechanical ventilation due to intolerance, shorten the treatment time, and promote its rehabilitation. It is worthy of application.

    Objective: To investigate the value of serum and gingival crevicular fluid myeloid cell-associated protein-8/14 (MRP-8/14), Toll-like receptor 4 (TLR4), Toll-like receptor 9 (TLR9) in evaluating periodontal-orthodontic efficacy in periodontitis patients with malocclusion. Methods: A total of 72 periodontitis patients with malocclusion admitted to Yongcheng People's Hospital from January 2022 to July 2023 were selected as the observation group, and 72 healthy subjects in the same period were selected as the control group. The levels of MRP-8/14, TLR4 and TLR9 in serum and gingival crevicular fluid were compared between the two groups before treatment. The indexes of serum and gingival crevicular fluid, inflammatory response indexes [high-sensitivity C-reactive protein (hs-CRP), soluble intercellular adhesion molecule (sICAM-1), monocyte chemoattractant protein-1 (MCP-1)] and periodontal indexes [plaque index (PLI), bleeding index (SBI), probing depth (PD)] were compared between the two groups before treatment and 3 months after treatment. The relationship between the indexes of serum and gingival crevicular fluid and the indexes of inflammatory response and periodontal indexes and the evaluation value were analyzed. Results: Before treatment, the levels of MRP-8/14, TLR4 and TLR9 in serum and gingival crevicular fluid in the observation group were higher than those in the control group(P＜0.05). The levels of MRP-8/14, TLR4 and TLR9 in serum and gingival crevicular fluid of patients with good efficacy and poor efficacy were significantly lower than those before treatment after 3 months of treatment (P＜0.05). The levels of MRP-8/14, TLR4 and TLR9 in serum and gingival crevicular fluid of patients with good efficacy were significantly lower than those of patients with poor efficacy before treatment and after 3 months of treatment (P＜0.05). The levels of SBI, PLI, PD, serum hs-CRP, sICAM-1 and MCP-1 in patients with good efficacy before treatment in the observation group were lower than those in patients with poor efficacy. MRP-8/14, TLR4 and TLR9 in serum and gingival crevicular fluid were positively correlated with hs-CRP, PLI, sICAM-1, SBI, MCP-1 and PD (P＜0.05). The AUC of combined evaluation of serum and gingival crevicular fluid indexes before treatment and 3 months after treatment was the largest (P＜0.05). Conclusion: The high expression of MRP-8/14, TLR4 and TLR9 in serum and gingival crevicular fluid of periodontitis patients with malocclusion is related to inflammatory response, periodontal index and periodontal-orthodontic efficacy. The combined prediction of periodontal-orthodontic efficacy has a high reference value.

    Objective: To investigate the effects of oral nutrition supplementation 10 days before surgery on preoperative nutritional status, immune function and postoperative infectious complications in patients with oral cancer. Methods: A total of 40 elderly patients with preoperative oral cancer who were screened by Nutritional Risk Screening 2002 (NRS-2002) score were divided into observation group and control group according to random number table method, with 20 patients in each group. The two groups were given dynamic nutritional support according to the target demand of energy and protein after operation. The control group was given routine nutritional education before operation. The observation group was given Nengquansu combined with whey protein powder oral nutrition supplement on the basis of the control group. The changes of nutritional status indexes, immune function indexes and postoperative infectious complications before and after intervention were compared between the two groups. Results: After intervention, the levels of albumin and prealbumin in the observation group were significantly higher than those in the control group, and the differences were statistically significant (P＜0.05), while there was no significant difference in RBC, HB between the observation group and the control group (P＞0.05). After intervention, IgA, CD4 and CD4/CD8 of the observation group were significantly higher than those of the control group, while C-reactive protein of the observation group was significantly lower than that of the control group, the differences were statistically significant (P＜0.05). After intervention, there was no significant difference in IgG, IgM, CD3, CD8 and NK cells between the observation group and the control group (P＞0.05). After intervention, the proportion of the total number of complications in the observation group was significantly lower than that in the control group, and the difference was statistically significant (P＜0.05). Conclusion: The preoperative oral nutritional supplement of Nengquansu combined with whey protein powder can improve the preoperative nutritional status and immune function of patients with oral cancer, and reduce the incidence of postoperative infectious complications.
