The accelerated development of modern medicine is a key force in safeguard human health， but there has also been a phenomenon of alienation. Interpreting the development of modern medicine from the perspective of Hartmut Rosa’s socially accelerated critical thought is a powerful explanatory framework for profoundly dissecting the development of medicine in the post-medical era and an entry point for diagnosing medical ailments. The development of medicine follows a “dynamic stability” model from three aspects， including technology， structure， and the pace of subjective life， entering a self-accelerating cycle system. In the infinite acceleration cycle， there are new manifestations of alienation， such as the abstraction of medical space， the subjectification of medical technology， the retreat of the humanistic spirit， the increasing poverty of life experience， and the elimination of doctor-patient identity. According to Rosa’s path of realizing the “good life”， the solution to medical alienation lies in establishing a “resonance” relationship， fostering the concept of medical humanization， constructing rational communication in medical language， and exploring new development concepts in medicine. These are effective ways to reconcile the relationship between medical development and other social factors.

OBJECTIVE To investigate the effects and mechanism of quercetin （QUE） on inflammatory response in allergic rhinitis （AR） model rats based on Toll-like receptor 4/interleukin 1 （IL-1） receptor-associated kinase/nuclear factor κB （TLR4/ IRAK4/NF-κB） signaling pathway. METHODS AR model rats were constructed by ovalbumin sensitization method. A total of 48 successfully constructed rats were randomly divided into AR group， QUE-L and QUE-H groups （i.g administration， 17.5， 35 mg/kg） and QUE-H+TLR4 activator lipopolysaccharide （LPS） group （i.g administration of 35 mg/kg QUE+intravenous administration of 0.4 mg/kg LPS via tail vein）， with 12 rats in each group. Another 12 normal healthy rats were selected as control group， once a day， for 21 consecutive days. After the last medication， rhinitis symptoms of rats in each group were scored. The serum levels of immunoglobulin E （IgE）， histamine （HIS）， and inflammatory factors were all detected. The proportions of regulatory T cells （Treg） and helper T cells 17 （Th17） cells in blood were detected， the Th17/Treg ratio was calculated， and the pathological condition of nasal mucosal tissue was observed. The expressions of TLR4/IRAK4/NF-κB pathway related protein in nasal mucosal tissue were determined. RESULTS Compared with control group， nasal mucosal tissue damage in the AR group was more severe， with partial shedding of epithelial cells， the proliferation of goblet cells， and obvious inflammatory cell infiltration. The rhinitis symptom score， the levels of IgE， HIS and IL-17， Th17 proportion， Th17/Treg ratio，p-IRAK4/IRAK4 and p-NF-κB p65/NF-κB p65 ratios as well as relative expression of TLR4 protein were increased significantly （P＜0.05）， while IL-10 level and Treg proportion were decreased significantly （P＜0.05）. Compared with AR group， the pathological injuries of nasal mucosa and the above indexes in QUE-L and QUE-H groups were all improved significantly （P＜0.05）. LPS treatment could reverse the improvement effects of high-dose QUE on histopathological damage to nasal mucosa tissue and the aforementioned indicators （P＜ 0.05）. CONCLUSIONS QUE can inhibit the inflammatory response in AR rats by inhibiting TLR4/IRAK4/NF- κB signaling pathway.

ObjectiveTo investigate the ameliorative effect of Xingpi capsules on functional dyspepsia（FD） and the potential mechanism. MethodsSixty SPF-grade male SD neonatal rats（7 days old） were randomly divided into the normal group（n=12） and the modeling group（n=48）， and the FD model was prepared by iodoacetamide gavage in the modeling group. After the model was successfully prepared， the rats in the modeling group were randomly divided into the model group， the low-dose and high-dose groups of Xingpi capsules（0.135， 0.54 g·kg^-1） and the domperidone group（3 mg·kg^-1）， with 12 rats in each group. Rats in the normal and model groups were gavaged with distilled water， and rats in the rest of the groups were gavaged with the corresponding medicinal solution， once a day for 7 d. The general survival condition of the rats was observed， and the water intake and food intake of the rats were measured， the gastric emptying rate and the small intestinal propulsion rate were measured at the end of the treatment， the pathological damage of the rat duodenum was examined by hematoxylin-eosin（HE） staining， and the expressions of colonic tight junction protein（Occludin） and zonula occludens protein-1（ZO-1） were detected by immunofluorescence. The differentially expressed genes in the duodenal tissues of the model group and the normal group， and the high-dose group of Xingpi capsules and the model group were detected by transcriptome sequencing after the final administration， and Gene Ontology（GO） and Kyoto Encyclopedia of Genes and Genomes（KEGG） enrichment analyses were carried out. The transcriptomic results were validated by Western blot， immunofluorescence， and real-time fluorescence quantitative polymerase chain reaction（Real-time PCR）， and the active ingredients of Xingpi capsules were screened for molecular docking with the key targets. ResultsCompared with the normal group， the general survival condition of rats in the model group was poorer， and the water intake， food intake， gastric emptying rate and small intestinal propulsion rate were all significantly reduced（P<0.05）， inflammatory infiltration was seen in duodenal pathology， and the fluorescence intensities of Occludin and ZO-1 in the colon were significantly reduced（P<0.01）. Compared with the model group， the general survival condition of rats in the high-dose group of Xingpi capsules improved significantly， and the water intake， food intake， gastric emptying rate and small intestinal propulsion rate were all significantly increased（P<0.05）， the duodenal pathology showed a decrease in inflammatory infiltration， and the fluorescence intensities of colonic Occludin and ZO-1 were significantly increased（P<0.01）. Transcriptomic results showed that Xingpi capsules might exert therapeutic effects by regulating the phosphatidylinositol 3-kinase（PI3K）/protein kinase B（Akt） through the key genes such as Slc5a1， Abhd6. The validation results showed that compared with the normal group， the phosphorylation levels of PI3K and Akt proteins， the protein expression level of interleukin（IL）-1β， and the fluorescence intensities of IL-6 and IL-1β were significantly increased in the model group（P<0.05， P<0.01）， and the mRNA levels of Slc5a1， Abhd6， Mgam， Atp1a1， Slc7a8， Cdr2， Chrm3， Slc5a9 and other key genes were significantly increased（P<0.01）. Compared with the model group， the phosphorylation levels of PI3K and Akt， the protein expression level of IL-1β and the fluorescence intensities of IL-6 and IL-1β in the high-dose group of Xingpi capsules were significantly reduced（P<0.05， P<0.01）， and the mRNA levels of Slc5a1， Abhd6， Mgam， Atp1a1， Slc7a8， Cdr2， Chrm3 and Slc5a9 were significantly reduced（P<0.05）. Weighted gene co-expression network analysis and molecular docking results showed that E-nerolidol and Z-nerolidol in Xingpi capsules were well bound to ABDH6 protein， and linarionoside A， valerosidatum and senkirkine were well bound to Slc5a1 protein. ConclusionXingpi capsules can effectively improve the general survival and gastrointestinal motility of FD rats， its specific mechanism may be related to the inhibition of PI3K/Akt signaling pathway to alleviate the low-grade inflammation of duodenum， and E-nerolidol， Z-nerolidol， linarionoside A， valerosidatum and senkirkine may be its key active ingredients.

ObjectiveTo explore the medical experience of caregivers of adolescent depression. MethodsIn-depth interviews were conducted with 35 caregivers of hospitalized adolescents with depression undergoing treatment， to explore their experiences and feelings during their children’s medical treatment. The Colaizzi phenomenological seven-step analysis method was employed to summarize and extract themes. ResultsA total of five themes were extracted， including the transformation of attitude towards the disease from denial to acceptance； the treatment process failing to meet expectations； complex emotional experiences featuring the coexistence of hope and disappointment； negative feedback regarding communication with medical staff； difficulties in accessing medical services， and the expectation for more assistance. ConclusionCaregivers lack sufficient knowledge about the disease during their children’s medical-seeking process， the disease treatment process fails to meet expectations， and there is negative feedback regarding communication with medical staff. Overall， medical experience is complex， and current medical services still have deficiencies. It is urgent to pay attention to the medical experiences of caregivers， enhance their disease cognition， standardize the diagnosis and treatment process， improve the effect of doctor-patient communication， expand multi-channel medical-seeking methods， and further meet the needs of patients and caregivers.

With the advancement of science and technology and the rapid rise of artificial intelligence （AI） in recent years， intelligent and digitalized lifestyles have become the norm. AI-generated content （AIGC） has entered people’s lives and shown a blowout development trend. As a major output of AIGC， virtual digital humans have evolved from being “unbearable to look at” to being “indistinguishable” from real humans， exerting multiple impacts on people’s lives to a certain extent. AIGC and virtual digital humans can bring spiritual comfort to users， drive technological progress， and promote social stability. Meanwhile， they also face a series of risks， such as infringement behaviors of portraits， data privacy risks， and the alienation of human nature. This paper proposed solutions from various aspects， such as legal and technical supervision， embedding ethical standards into technology development， raising the market thresholds， and strengthening public publicity， striving to guide science and technology towards good.

Pharmacotherapy is the primary treatment method for hyperthyroidism. Antithyroid drugs can induce liver injury， and the diagnosis of drug-induced liver injury is mostly exclusive based on medical history collection， clinical symptoms， serum biochemistry， radiological examination， and histology. According to the severity of liver injury， drug-induced liver injury can be classified into mild， moderate， severe， and fatal degrees. Drug withdrawal may not be necessary for patients with mild liver injury， but regular monitoring of liver function is required； in severe cases， patients may develop liver failure， which may lead to a mortality rate， and early identification， timely drug withdrawal， and reasonable pharmacotherapy can help to avoid fatal consequences. The treatment principles of liver injury induced by antithyroid drugs include promoting the recovery of liver injury， preventing the severe exacerbation and chronicity of liver injury， and reducing the risk of death. Standardized medication， timely monitoring， early identification， and early treatment are important measures for the prevention and treatment of liver injury induced by antithyroid drugs.

Objective To construct a universal influenza mRNA vaccine and evaluate its immunogenicity.Methods The antigen sequence of hemagglutinin(HA),nucleoprotein(NP)and matrix protein 2 ectodomain(M2e)in influenza A/California/04/2009 was optimized.HA,NP and 3 tandem M2e(3M2e)were cloned into pcDNA3.1 vector,respectively.Then the mRNAs were synthesized by linearization,in vitro transcription,enzymatic capping and enzymatic tailing,and named as mRNA-HA,mRNA-NP and mRNA-3M2e,respectively.The protein expression of the 3 kinds of mRNAs in 293T cells was detected by immunofluorescence assay.Comb-mRNA vaccine was prepared by enveloped mRNA-HA,mRNA-NP and mRNA-3M2e with lipid nanoparticles,respectively,and the particle size and potential were identified.Twenty-eight 6-week-old female BALB/c mice(18～22 g)were randomly divided into LNP group(n=14)and Comb-mRNA group(n=14).Hemagglutination inhibition(HI)method and microneutralization(MN)test were used to evaluate the serum antibody titer induced by Comb-mRNA vaccines.The mice were infected by 5LD50 wild-type H1 N1 influenza virus to evaluate the protective efficacy.Results The mRNA-HA,mRNA-NP and mRNA-3M2e were successfully constructed,and the 3 mRNAs could be expressed in 293T cells.The average size of mRNA encapsulated by lipid nanoparticles was 119.53±6.5 nm,and the average potential was-8.23±1.3 mV.The geometric mean titer(GMT)of HI and MN in the Comb-mRNA group were 179.6 and 201.6,compared with the LNP group.The ratio of IFN-γ+CD4+/CD8+Tcells was increased.The Comb-mRNA group could provide protection against 5LD50 wild type influenza H1 N1 virus after 2 weeks of booster immunization.Conclusion Comb-mRNA,an influenza vaccine candidate,can induce immune responses and protect mice from influenza virus challenge.
