Objective:
To identify the effective needs of college students for dietary nutrition health education content, so as to provide a scientific basis for optimizing the health education strategies in colleges.
Methods:
The literature analysis method, focus group interviews and Delphi expert consultation method were used to construct a survey questionnaire on dietary nutrition health education for college students. From January to March 2024, a total of 597 college students from six colleges in Shandong Province were selected through convenience sampling to complete the questionnaire independently by scanning the two dimensional code on questionnaire star. The Kano model was used to define the content demands of college students for dietary nutrition education, and the differences in demands were analyzed by calculating satisfied influence (SI) and dissatisfied influence (DSI).
Results:
The compiled questionnaire was divided into 7 dimensions and 25 items. The overall demand level analysis of college students included 3 essential attribute demands, namely, the recommended intake and various forms of dairy products (34.17%), the role of whole grains in health with their scientific intake forms and recommended amounts (31.99%), and the intake of beans (30.15%); 7 expected attribute demands included the introduction of recommended intensity of different activities (35.01%), how to achieve a healthy weight and the balance between diet and exercise (41.54%), the energy consumed by different exercises in a unit of time ( 38.36 %), the selection of healthy snacks (36.68%), the types of infectious diseases of the digestive system and how to prevent and control them (25.96%), the causes and judgments with manifestations of nutrition related diseases among college students ( 28.14 %), and the hotspots of attention on nutrition related diseases among college students (24.46%); 4 attractive attribute demands contained the introduction of the recommended activity levels for different periods such as daily and weekly (28.81%), the introduction of the importance of activities and the harm of prolonged sitting and ways to avoid it (28.64%), the nutritional value of animal foods and eating suggestions (23.45%), and the scientific intake suggestions for various processed animal foods (22.11%); the remaining were 11 attribute demands with no differences. In the quadrant diagram analysis, the demand items located in the maintenance zone, competitive advantage zone, improvement zone, and minor improvement zone were 5, 5, 8, and 7, respectively.
Conclusions
College students have different demands in dietary nutrition health education, and whether these demands are met affects their satisfaction in different ways. Among them, education on the intake of dairy products, whole grains, and beans has the greatest impact on satisfaction.

Myasthenia gravis is an autoimmune disorder characterized by impaired neuromuscular transmission. Thymectomy is one of the therapeutic options for acetylcholine receptor antibody-positive myasthenia gravis patients. The quality of perioperative care is directly associated with surgical safety and patient outcomes. However, there is currently a lack of specialized nursing consensus or guidelines specifically addressing the care of these patients domestically or internationally. To promote the standardization and normalization of perioperative nursing care for myasthenia gravis patients undergoing thymectomy and to ensure treatment efficacy, a panel of 57 experts from relevant fields was convened. Based on evidence-based medicine and clinical practice experience, discussions were held on various aspects including condition assessment, nutritional support, medication management, and airway care, resulting in a consensus with 18 final recommendations by using the Delphi method through two rounds of expert consultation. This consensus aims to provide a scientific reference for the perioperative nursing care of myasthenia gravis patients undergoing thymectomy.

OBJECTIVE To investigate the effects of subanesthetic dose of esketamine on postoperative anxiety and recovery in patients undergoing laparoscopic cholecystectomy. METHODS A total of 200 patients scheduled for laparoscopic cholecystectomy at Suzhou Ninth Hospital Affiliated to Soochow University from January 2023 to December 2024 were randomly assigned to control group (n=100) and observation group (n=100). One minute before the initiation of anesthesia, patients in the control group received intravenous injections of Propofol emulsion injection, Sufentanil citrate injection, and Succinylcholine chloride injection. On this basis, patients in the observation group received an intravenous injection of Esketamine hydrochloride injection. The anxiety status of patients in both groups was compared, along with their general intraoperative conditions (including sufentanil dosage, duration of pneumoperitoneum, operative time, anesthesia time, and extubation time), postoperative recovery, incidence of adverse reactions, and the need for dezocine rescue analgesia. Heart rate and mean arterial pressure, entropy index (state entropy and response entropy), inflammatory marker levels [interleukin-6 (IL-6) and C-reactive protein (CRP)], numerical rating scale (NRS) for pain intensity were compared between the two groups at different time points. RESULTS No significant differences were found between the two groups in pneumoperitoneum duration, operative time, anesthesia time,extubation time, incidence of postoperative dry mouth, entropy index or length of stay in the post-anesthesia care unit (P>0.05). Compared with the control group, the observation group showed significantly lower postoperative STAI-S scores, reduced intraoperative sufentanil consumption, decreased incidence of postoperative nausea, vomiting, and shivering, the need for dezocine rescue analgesia, as well as lower plasma IL-6 and CRP levels at 24 h after surgery, and NRS (P<0.05). The heart rate and mean arterial pressure of patients in the observation group at the start of surgery, end of surgery, and during extubation were all significantly higher than those in the control group (P<0.05). CONCLUSIONS Subanesthetic dose of esketamine can effectively alleviate postoperative anxiety, reduce intraoperative opioid consumption, suppress postoperative inflammatory response, relieve postoperative pain, and promote recovery in patients undergoing laparoscopic cholecystectomy.

ObjectiveTo construct a standardized diagnostic scale for Qi-Yin deficiency with blood stasis syndrome in diabetic macrovascular disease. MethodsLiterature related to Qi-Yin deficiency with blood stasis syndrome in diabetic macrovascular disease was retrieved from CNKI, VIP, and Wanfang databases. Diagnostic information from four diagnostic methods was extracted and standardized, with items having a frequency of ≥15 included in the item pool. A three-round Delphi expert consultation was conducted, screening items using support degree, mean score, rank sum, and coefficient of variation. Item weights were determined using analytic hierarchy process (AHP), gactor analysis (FA), and combined weighting method (CWM). The optimal weighting method was selected by comparing the area under the receiver operating characteristic (ROC) curve (AUC). The Youden index was calculated to establish the diagnostic cutoff value, which was proportionally scaled. ResultsA total of 102 studies were included. Thirty-five items were incorporated into the item pool. The authority coefficients for the three Delphi rounds were 0.82, 0.85, and 0.86, with coordination coefficients of 0.648, 0.538, and 0.506, respectively. Fifteen items were retained after screening. ROC curve analysis showed the AUC ranking as FA > CWM > AHP. The maximum Youden index was 0.814, corresponding to a diagnostic cutoff of 8.361 (scaled to 40 points). The final scale adopted a structured diagnostic framework: the symptom dimension requires at least 2 items, and the tongue or pulse dimension requires at least 1 category. ConclusionThis study developed a standardized diagnostic scale for Qi-Yin deficiency with blood stasis syndrome in diabetic macrovascular disease. Core items were screened via the Delphi method, with factor analysis identified as the optimal weighting method through AUC comparison. The diagnostic threshold (40 points) and structured diagnostic framework provide a quantitatively clear, clinically practical tool.

ObjectiveThis study aims to explore the potential of different orders of magnitude single-nucleotide polymorphism (SNP) locus combinations for predicting distant kinship relationships. A high-density SNP locus set was constructed, and a comprehensive assessment of its inference capability was conducted. MethodsFirstly, we selected three commercial chip panels, CGA (Chinese genotyping array, Illumina), GSA (Global screening array, Illumina), Affy (23MF_V2 high-density SNP array, Affymetrix) and merged them after quality control, forming a high-density SNP locus panel(1 180 k). Secondly, we selected 161 samples and collected their peripheral blood samples by using whole-genome sequencing technology. Within this sample population, the levels of kinship relationships fully covered the range from level 1 to level 9, and the number of kinship pairs at each level was consistently maintained at over 50 pairs. From 161 samples data of whole-genome sequencing, the 1 180 k locus set was extracted, which is referred to as the high-density SNP locus set in the following text. The kinship inference was conducted using the identity-by-descent (IBD) algorithm with the selected optimal parameters. To comprehensively evaluate the performance of the high-density SNP locus set in kinship inference, we compared it with the three commercial chip panels, the intersection of these three chip loci, and the control sets constructed by randomly reducing the number of the high-density SNP locus set. Based on the changes in the IBD lengths, as well as the dynamic trends in prediction accuracy, we conducted a scientific assessment of the kinship inference capability of the high-density SNP locus set. ResultsAfter screening, a set of 1 184 334 autosomal SNPs was obtained. During the process of screening the optimal IBD length threshold, the result revealed that 0 cM, 1 cM, and 2 cM all demonstrated good applicability. However, to avoid the issue of a large amount of redundant information caused by setting a too low IBD length threshold, this study ultimately selected 2 cM as the optimal threshold. Compared with the average results of three chip panels, the high-density SNP locus set increased the total IBD length and the average IBD length across levels 1-9; the accuracy of the confidence interval for level 8 was 70.97%, which represented a 3.50% improvement; the average confidence interval accuracy for levels 1-8 was 91.39%, representing a 1.00% increase; and the false negative rates at levels 8 and 9 were reduced by 2.42% and 6.76%, respectively. The system efficacy of the high-density SNP locus set for kinship inference of first to eighth degree relationships reached 98.91%. Through random reduction of the high-density SNP locus set results, it is found that increasing the number of SNPs with the panel, the detection efficiency of IBD length showed a significant upward trend. At the same time, the overall trend in the accuracy of kinship relationship prediction as well as the confidence interval accuracy also indicated that both metrics steadily increased with the addition of more loci. ConclusionThe results show that the high-density SNPs panel significantly enhances the efficacy of distant kinship inference, accurately covering kinship degrees, with the average confidence interval accuracy for first to eighth degree relationships stably above 90%. The study finds that increasing the number of SNPs panel can improve the ability to predict distant kinship.

ObjectiveTo investigate the effect of interfering with long noncoding RNA (LncRNA) small nucleolar RNA host gene16 (SNHG16) on improving angiogenesis of ectopic endometrial stromal cells (EScs) in adenomyosis (AM) by targeting upregulation of miRNA (miR)-141-3p and inhibition of high mobility group box-1 protein (HMGB1). MethodsThe expression levels of SNHG16, miR-141-3p and HMGB1 mRNA in endometrial tissues of 52 patients with adenomyosis (AM group) and 52 patients who needed hysterectomy due to cervical cancer or ovarian cancer (control group) were detected by quantitative reverse transcription polymerase chain reaction (qRT-PCR). Y14 cells were divided into small hairpin RNA (shRNA) NC group, shRNA SNHG16 group, shRNA SNHG16+miR-141-3p inhibitor (inhibitor) group, shRNA SNHG16+inhibitor NC group and blank group. The targeting relationship between miR-141-3p and SNHG16 as well as HMGB1 was verified. The expression levels of SNHG16, miR-141-3p and HMGB1 mRNA in Y14 cells were detected by qRT-PCR. CCK-8 and Transwell assay were used to detect cell proliferation, invasion and migration. Microvascular density (MVD) was determined by immunofluorescence. The expressions of hypoxia-inducing factor α (HIF-1α), cyclooxygenase-2 (Cox-2), vascular endothelial growth factor (VEGF) and HMGB1 were detected by Western blot. ResultsThe expression of SNHG16 and HMGB1 mRNA in AM group was higher than that in control group, but the expression of miR-141-3p was lower than that in control group (P0.05). The expression of SNHG16, HMGB1 mRNA, proliferation rate, migration, invasion number, MVD, expression of VEGF, HIF-1 α, Cox-2, and HMGB1 proteins in the shRNA SNHG16 group were lower than those in the blank group and shRNA NC group, while the expression of miR-141-3p was higher than that in the blank group and shRNA NC group (P0.05). Inhibition of miR-141-3p reversed the improvement of EScs angiogenesis by interfering with SNHG16. ConclusionInterference with LncRNA SNHG16 improves EScs angiogenesis and inhibits proliferation, migration, and invasion of EScs by targeting upregulation of miR-141-3p and inhibition of HMGB1.

Pneumoconiosis is a chronic interstitial lung disease caused by occupational exposure to mineral dust, characterized by persistent inflammation and progressive pulmonary fibrosis. Effective therapeutic options, however, remain limited. Recent multi-omics studies have revealed that glucose metabolic reprogramming, particularly the abnormal activation of glycolysis, plays a critical role in the pathogenesis of fibrotic diseases. This review summarized the key components involved in glycolytic reprogramming, including rate-limiting enzymes such as hexokinase, phosphofructokinase, pyruvate kinase, and lactate dehydrogenase, as well as regulatory factors such as hypoxia-inducible factor-1α (HIF-1α) and AMP-activated protein kinase (AMPK). Their roles in metabolic regulation and fibrogenesis were elaborated. Special emphasis was placed on alveolar macrophages and fibroblasts, in which enhanced glycolysis and lactate accumulation drive inflammatory responses and collagen deposition, contributing to disease progression. Advances on pharmacological agents such as nintedanib, 2-deoxyglucose, quercetin, metformin, and resveratrol were reviewed, highlighting their antifibrotic potential through modulation of glycolytic enzymes or related signaling pathways. Additionally, the interactions between glycolysis and fatty acid metabolism, amino acid metabolism, and oxidative phosphorylation were discussed, underscoring the significance of multi-pathway coupling in pneumoconiosis. Metabolic abnormalities in pneumoconiosis result from multi-level interactions across cells, molecules, and tissues. Consequently, future therapeutic strategies should shift from single-target interventions toward coordinated regulation of multiple pathways, integrating tissue-targeted drug delivery, metabolism-based stratified interventions, and multi-target combination therapies to achieve precision and personalized treatment.

ObjectiveTo study the mechanism of compound Xishu granules (CXG) in inhibiting the proliferation of hepatocellular carcinoma cells by regulating ferroptosis. MethodsThe transplanted tumor model of human Huh7 was established with nude mice and the successfully modeled mice were randomized into model, Fufang Banmao (0.21 g·kg-1), low-dose (1.87 g·kg-1) CXG, medium-dose (3.74 g·kg-1) CXG, and high-dose (7.49 g·kg-1) CXG groups. Mice were administrated with drinking water or CXG for 28 days, and the body weight and tumor volume were measured every 4 days. Hematoxylin-eosin staining was employed to observe the histopathological changes of tumors. The cell-counting kit-8 (CCK-8) was used to examine the survival rate of Huh7 cells treated with different concentrations (0, 31.25, 62.5, 125, 250, 500, 1 000 mg·L-1) of CXG for 24 h and 48 h. CA-AM, DCFH-DA, and C11-BODIPY581/591 fluorescent probes were used to determine the intracellular levels of ferrous ion (Fe2+), reactive oxygen species (ROS), and lipid peroxide (LPO), respectively. The colorimetric method was employed to measure the levels of glutathione (GSH) and superoxide dismutase (SOD). Western blot was employed to determine the protein levels of glutathione peroxidase 4 (GPX4), transferrin receptor 1 (TFR1), and ferritin heavy chain 1 (FTH1), respectively. ResultsIn the animal experiment, compared with the model group, the drug treatment groups showed reductions in the tumor volume from day 12 (P<0.01). After treatment, the Fufang Banmao and low-, medium-, and high-dose CXG groups had lower tumor volume, relative tumor volume, and tumor weight than the model group (P<0.05), with tumor inhibition rates of 48.99%, 79.93%, 91.38%, and 97.36%, respectively. Moreover, the CXG groups had lower tumor volume and relative tumor volume (P<0.05 in all the three dose groups) and lower tumor weight (P<0.05 in medium-dose and high-dose groups) than the Fufang Banmao group. Compared with the model group, the drug treatment groups showed reduced number of tumor cells, necrotic foci with karyopyknosis, nuclear fragmentation, and nucleolysis, and the high-dose CXG group showed an increase in the proportion of interstitial fibroblasts. In the cell experiment, compared with the blank group, CXG reduced the survival rate of Huh7 cells in a dose-dependent manner after incubation for 24 h and 48 h (P<0.05). Compared with the blank group, the RSL3 group and the low-, medium-, and high-dose CXG groups showed a decrease in the relative fluorescence intensity of CA-AM and increases in the fluorescence intensity of DCFH-DA and fluorescence ratio of C11-BODIPY581/591, which indicated elevations in the levels of Fe2+ (P<0.01), ROS (P<0.05), and LPO (P<0.01), respectively. Compared with the blank group, the RSL3 and low-, medium-, and high-dose CXG groups showed lowered levels of GSH and SOD (P<0.05). In addition, the RSL3 group and the medium- and high-dose CXG groups showed down-regulated expression of GPX4 and FTH1 (P<0.05), and the low- and high-dose CXG groups presented up-regulated expression of TFR1 (P<0.05). ConclusionCXG suppresses the proliferation of hepatocellular carcinoma cells by inducing ferroptosis via downregulating the GSH-GPX4 signaling axis and increasing intracellular Fe2+and LPO levels.

ObjectiveTo investigate the mechanism of liver injury induced by tripterygium glycosides tablets (TG) and the molecular mechanism of compound glycyrrhizin tablets (CG) in alleviating the abnormalities of cholesterol metabolism caused by TG via cholesterol metabolism. MethodsAccording to the body weights, male Sprague-Dawley (SD) rats were randomly grouped as follows: control (pure water), low-dose TG (TG-L, 189.0 mg·kg-1·d-1), high-dose TG (TG-H, 472.5 mg·kg-1·d-1), TG-L+CG (189.0 mg·kg-1·d-1 TG + 20.25 mg·kg-1·d-1 CG), and TG-H+CG (472.5 mg·kg-1·d-1 TG + 20.25 mg·kg-1·d-1 CG), with 6 rats in each group. Rats were administrated with corresponding drugs once daily for 3 weeks. At the end of the last administration, the mRNA and protein levels of liver X receptor-alpha (LXR-α), low-density lipoprotein receptor (LDLR), adenosine triphosphate-binding cassette transporter A1 (ABCA1), adenosine triphosphate-binding cassette transporter G1 (ABCG1), 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR), cholesterol 7α-hydroxylase (CYP7A1), cholesterol 12α-hydroxylase (CYP8B1), and sterol 27-hydroxylase (CYP27A1) in the liver tissue were determined by Real-time PCR and Western blotting, respectively. The level of 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMG-CoAR), a regulatory enzyme of cholesterol synthesis, was measured by enzyme-linked immunosorbent assay (ELISA). HepG2 cells were used to observe the effect of TG on the cell proliferation in vitro. Specifically, HepG2 cells were grouped as follows: Low-dose TG (TG-l, 15 mg·L-1), medium-dose TG (TG-m, 45 mg·L-1), high-dose TG (TG-h, 135 mg·L-1), fenofibrate (FB, 10 μmol·L-1), CG extract, TG-h+FB (135 mg·L-1 TG + 10 μmol·L-1 FB), TG-m+FB (45 mg·L-1 TG + 10 μmol·L-1 FB), TG-l+FB (15 mg·L-1 TG + 10 μmol·L-1 FB), TG-h+CG (135 mg·L-1 TG + 60 μmol·L-1 CG), TG-m+CG (45 mg·L-1 TG + 60 μmol·L-1 CG), and TG-l+CG (15 mg·L-1 TG + 60 μmol·L-1 CG). The mRNA and protein levels of LXR-α, ABCG1, LDLR, CYP7A1, CYP8B1, and CYP27A1 in HepG2 cells were determined by Real-time PCR and Western blotting, respectively. ResultsThe rat experiment showed that compared with the control group, the TG-H group showed down-regulated mRNA levels of CYP7A1, CYP8B1, and CYP27A1 in the liver tissue (P<0.05, P<0.01), which were up-regulated by the application of CG (P<0.05, P<0.01), and the TG-H+CG group showed up-regulated mRNA level of LDLR (P<0.01). Compared with the control group, the TG-L and TG-H groups showed down-regulated protein levels of LDLR, CYP7A1, and CYP8B1 in the liver tissue (P<0.05, P<0.01). In addition, the protein levels of ABCG1 and LXR-α were down-regulated in the TG-H and TG-L groups, respectively (P<0.05). Compared with TG alone, TG+CG up-regulated the protein levels of ABCG1 and LDLR (P<0.05, P<0.01), and the protein levels of CYP7A1 and CYP8B1 in the TG-H+CG group were up-regulated (P<0.05, P<0.01). The cell experiment showed that compared with the control group, the TG-h group presented up-regulated mRNA level of LXR-α (P<0.01), and the TG-m and TG-h groups showcased down-regulated mRNA levels of LDLR and CYP7A1 (P<0.01) and up-regulated mRNA level of CYP27A1 (P<0.01) in HepG2 cells. The combination of CG with TG restored the above changes (P<0.01). Western blotting results showed that compared with the control group, the TG-m and TG-h groups showed down-regulated protein levels of LXR-α, ABCG1, LDLR, CYP7A1, CYP8B1, and CYP27A1 in HepG2 cells (P<0.01). Compared with the TG-h group, the TG-h+CG group showed up-regulated protein level of LDLR (P<0.05). Compared with the TG-m group, the TG-m+CG group showcased up-regulated protein levels of LDLR, ABCG1, CYP7A1, and CYP27A1 (P<0.05, P<0.01). ConclusionThe administration of TG at 189.0, 472.5 mg·kg-1 for 3 weeks could modulate the signaling pathways associated with cholesterol efflux, endocytosis, and cholesterol biotransformation in hepatocytes, leading to the accumulation of cholesterol and subsequent liver injury in rats. CG could ameliorate the liver injury induced by lipid metabolism disorders caused by TG by up-regulating the expression of LXR-α, LDLR, ABCG1, CYP7A1, CYP8B1, and CYP27A1 to promote cholesterol biotransformation.
