Abstract To promote the mental health of college students and build campus based psychological support system, the study explains that current applications of digital health interventions (DHIs) include independent forms based on a single technology or platform, as well as integrated forms that combine multiple digital technologies with traditional mental health services. These interventions have positive effects on alleviating negative emotions among college students, enhancing psychological resilience, improving quality of life, and ameliorating academic performance. However, differences still exist in the stability of intervention effects. Future development requires continuous improvement in institutional construction, ethical governance and capacity building.

Colorectal inflammatory cancer transformation poses a major risk to patients with colitis. Patients with chronic intestinal inflammation have an approximately 2-3 folds increased risk of developing colorectal cancer (CRC). Unfortunately, there is currently no effective intervention available. Huangqin decoction (HQD), a well-known traditional Chinese medicine (TCM) formula, is frequently clinically prescribed for treating patients with colitis, and its active ingredients have effective antitumour efficacy. Nonetheless, the mechanism of HQD-mediated prevention of colorectal inflammatory cancer transformation remains unclear. A strategy integrating metagenomic, lipidomic, and messenger RNA (mRNA) sequencing analysis was used to investigate the regulatory effects of HQD on the gut microbiome, metabolism and potential mechanisms involved in colorectal inflammatory cancer transformation. Our study revealed that HQD suppressed colorectal inflammatory cancer transformation, which was associated with enhanced intestinal barrier function, decreased the inflammatory response, and regulation of the gut microbiome. Notably, cohousing experiments revealed that the transfer of the gut microbiome from HQD-treated mice largely inhibited the pathological transformation of colitis. Moreover, gut microbiome transfer from HQD-treated mice primarily resulted in the altered regulation of fatty acid metabolism, especially the remodeling of arachidonic acid metabolism, which was associated with the amelioration of pathological transformation. Arachidonic acid metabolism and the key metabolic enzyme arachidonic acid 12-lipoxygenase (ALOX12) were affected by HQD treatment, and no obvious protective effect of HQD was observed in Alox 12 ^-/- mice, which revealed that ALOX12 was a critical mediator of HQD protection against colorectal inflammatory cancer transformation. In summary, multiple omics analyses were applied to produce valuable data and theoretical support for the application of HQD as a promising intervention for the transformation of inflammatory CRC.

Objective:To investigate the role of the nuclear factor-kappa B (NF-κB) /nuclear factor E2 related factor 2 (Nrf2) pathway in the occurrence of lung tissue in the pulmonary alveolar proteinosis (PAP) model of rats induced by indium tin oxide nanoprticles (Nano-ITO) .Methods:In October 2019, 120 SD rats were divided into 3, 7, 14, 28, 56, and 84 day Nano ITO exposure groups and corresponding time point control groups, with 10 rats in each group; the exposure group was treated with 6 mg/kg·bw Nano-ITO via non exposed tracheal injection, twice a week. Time-course studies were performed to examine the pulmonary toxicity induced by Nano-ITO. At the end of the experiment, cytokines levels and oxidative stress were analyzed in the bronchoalveolar lavaged fluid (BALF). Rat lung tissues were also harvested for staining with HE, PAS, Masson, and Oil Red O. Ultrastructure of lung tissue cells was observed by transmission electron microscope. The localization and expression of NF-κB p65, IκB-α, IKK-β, Nrf2, NQO1, HO-1 were observed by immunohistochemistry, Western blot and real-time fluorescent quantitative PCR. The comparison between the two groups was analyzed by independent sample T test, and the comparison between the multiple groups was analyzed by one-way ANOVA.Results:Nano-ITO intratracheal instillation caused pulmonary toxicity by inducing acute inflammation, granuloma (nodule) formation, and alveolar proteinosis. ELISA analysis showed that, compared with the corresponding time points control groups, the levels of superoxide dismutase (SOD), total antioxidant capacity (T-AOC), malondialdehyde (MDA), interleukin (IL) -1β, IL-6, tumor necrosis factor alpha (TNF-α), IL-10, total protein (TP), and lactate dehydrogenase (LDH) in BALF of rats exposed to Nano ITO were all increased ( P<0.05) ; The protein expression of Nrf2 and NF-κB p65 was upregulated in rat lung tissue, while the protein expression of KK-β was increased ( P<0.01). Nrf2 and its downstream proteins NQO1 and HO-1 were highly expressed in Nano-ITO-induced PAP rat. Conclusion:NF-κB/Nrf2 signal pathway is involved in the process of Nano-ITO induced pulmonary alveolar proteinosis in rats.

Objective To construct a swallowing dynamic model for simulating dysphagia caused by reduced tongue movement am-plitude.Methods A swallowing dynamic model was established based on medical imaging data from CT and videofluoroscopic swallowing study(VFSS).The finite element method was used to simulate soft tissues,while the smoothed parti-cle hydrodynamics method(SPH)was used to simulate bolus.The model's posture at each time point was com-pared with the imaging data of VFSS from twelve patients with dysphagia,and a normalization method was used for quantitative evaluation of the model's validity.By adjusting the tongue movement amplitude under different viscosity conditions,the role of tongue movement in the swallowing process was investigated,and the swallow-ing safety and efficiency were assessed.Results The tongue posture and bolus trajectory presented by the swallowing dynamic model were consistent with the VFSS imaging.The brightness in the epiglottis area in VFSS images correlated with the equivalent brightness of SPH particles in the simulation results(r=0.97).As the tongue movement amplitude reducing by 20%,the num-ber of aspirated particles,swallowing efficiency and the average velocity of bolus particles in the oropharyngeal cavity all performed well.Pudding-like fluids exhibited favorable swallowing characteristics even when tongue movement amplitude reducing significantly.Conclusion The swallowing dynamic model can simulate the human swallowing process,providing good support for re-habilitation training of patients with dysphagia and the development of specialized medical foods,demonstrating significant potential for clinical applications.

OBJECTIVE: To analyze the diversity of Duffy blood group gene among ethnic Hui population from Henan Province using PacBio long-read sequencing technique. METHODS: Randomly select 30 individuals with three generations of Hui ancestry from Henan as the study subjects. Full-length sequences of the Duffy blood group gene were obtained through PacBio long-read sequencing. Distribution of the predicted phenotype and genotype frequency were determined, and the linkage between Duffy haplotypes and variation sites was analyzed. Genetic diversity, natural selection pressure, and population genetic characteristics were evaluated. This study was approved by the Second Affiliated Hospital of Zhengzhou University (Ethics No. 2022223). RESULTS: The predicted Duffy blood group phenotype in the Henan Hui population was predominantly Fy(a+b-). Three novel SNPs in the FY*01 allele were identified, with a total frequency of 13.33%, among which FY*01.NEW1 (c.199C>T) was the most common. A total of 32 variant sites were identified, with 28 located in intronic regions, indicating that genetic diversity was primarily concentrated in introns. The Duffy blood group gene was under negative selection pressure (dN/dS < 1, Tajima's D, Fu and Li's D* and F* significantly deviated from 0), suggesting overall conservation. The allele frequencies of Duffy blood group in the Henan Hui population was similar to that of the Xinjiang Hui, Xinjiang Kazakh, Inner Mongolia Mongolian, and Yuncheng Han populations, but significantly different from those of most Han and other ethnic groups (P < 0.05). CONCLUSION This study revealed the characteristics of the Duffy blood group gene among the Henan Hui population and demonstrated the significant advantages of PacBio long-read sequencing technique in haplotype analysis, genetic diversity study, and novel mutation identification.
