ObjectiveTo investigate the mechanisms by which Renshentang treats atherosclerosis （AS） in mice， focusing on the regulation of endothelial inflammatory responses mediated by transient receptor potential vanilloid subtype 1 （TRPV1）. MethodsAn AS model was established in apolipoprotein E knockout （ApoE^-/-） mice fed a high-fat diet. The mice were randomly divided into a simvastatin group （0.02 g·kg^-1·d^-1） and low-， medium-， and high-dose Renshentang groups （1.77， 3.54， 7.08 g·kg^-1·d^-1）， with 12 mice in each group. ApoE^-/- mice were fed a high-fat diet and treated simultaneously. C57BL/6J mice fed a normal diet served as the normal group （n=9）. After continuous administration for 12 weeks， mice were anesthetized and the aortas were collected. Oil Red O staining was used to observe lipid plaque formation in the aorta. Hematoxylin-eosin （HE） staining was performed to examine pathological changes in the aortic root. Immunohistochemistry was used to analyze the levels of pro-inflammatory factors tumor necrosis factor-α （TNF-α） and interleukin-1β （IL-1β）， as well as the expression of TRPV1， phosphorylated phosphoinositide 3-kinase （p-PI3K）， and phosphorylated protein kinase B （p-Akt） in the aortic root. Real-time quantitative polymerase chain reaction （Real-time PCR） was used to detect endothelial nitric oxide synthase （eNOS） mRNA expression in the aorta， and Western blot was used to detect TRPV1 protein expression. ResultsCompared with the normal group， the model group showed a significant increase in aortic plaque formation （P<0.01） and significantly elevated levels of TNF-α and IL-1β in the aortic root （P<0.01）. The expression levels of TRPV1， p-PI3K， and p-Akt were decreased （P<0.05， P<0.01）， and eNOS mRNA expression was reduced （P<0.05， P<0.01）. Compared with the model group， all Renshentang groups significantly reduced aortic plaque formation （P<0.01）， significantly decreased TNF-α and IL-1β levels （P<0.01）， and markedly increased the expression levels of TRPV1， p-PI3K， p-Akt， and eNOS mRNA （P<0.05， P<0.01）. ConclusionRenshentang may inhibit endothelial inflammation and suppress the formation of AS by increasing TRPV1 protein expression and up-regulating the PI3K/Akt/eNOS signaling pathway， which may be one of the molecular mechanisms underlying its therapeutic effect against AS.

Metabolic associated fatty liver disease （MAFLD） is the main type of chronic liver disease in the world， with an increasingly higher incidence rate and a younger age of onset. At present， the treatment of MAFLD mainly depends on lifestyle intervention and comorbidity management， and there is still a lack of effective drugs for MAFLD itself. As a classic nonsteroidal anti-inflammatory drug of the salicylic acid family， aspirin can intervene in the pathological process of MAFLD by regulating lipid metabolism， relieving insulin resistance， reducing liver inflammation and oxidative stress response， exerting an anti-liver fibrosis effect， and inhibiting hepatocellular carcinoma， and therefore， it has the value of preventing disease onset， delaying disease progression， and reversing disease condition. This article systematically reviews the mechanism of action and safety of aspirin in the treatment of MAFLD， in order to provide more drug treatment options for MAFLD patients.

Uveal melanoma(UM)is the most common primary intraocular malignancy in adults and arises predominantly from the choroid. Mitochondria, as essential organelles, not only fuel energy metabolism, but also orchestrate signal transduction and apoptosis. Recent studies have progressively uncovered the multifaceted roles of mitochondria in UM, including mitochondrial DNA copy-number alterations, reprogramming of mitochondria-related metabolic genes, and mitochondria-dependent autophagy. Moreover, mitochondria modulate UM progression partly through the PI3K/AKT axis. Natural compounds and small-molecule drugs that impair mitochondrial function have also shown promising activity in inducing UM cell dysfunction. These findings provide new insights into UM pathogenesis and highlight mitochondria as potential therapeutic targets.

Informed consent constitutes a fundamental ethical principle in medical practice. With the in-depth integration of generative artificial intelligence （AI） represented by Chat Generative Pre-trained Transformer （ChatGPT） with medicine， it has brought revolutionary development to traditional informed consent while also introducing new ethical challenges. ChatGPT offers features such as improving the readability of informed consent content， enhancing its comprehensiveness and accuracy， and increasing the convenience of obtaining informed consent. However， as the application of ChatGPT in informed consent is still in the exploratory stage， it is imperative to proactively and fully consider the accompanying ethical issues， such as information security， liability determination， transparency， and fairness. This paper conducted an ethical analysis on the challenges faced by generative AI， represented by ChatGPT， in the application of informed consent and proposed countermeasures， such as upholding free and fully informed consent， strengthening the balance of rights and obligations in informed consent， and establishing a transparent and fair supervision mechanism. The aim was to promote the ethically compliant， orderly， and controllable development of generative AI in the field of medical informed consent.

Objective:To explore the correlation between serum nidogen-2 (NID-2) and thoracic aortic calcification in patients with chronic kidney disease (CKD), and construct a risk prediction model based on NID-2 to evaluate its value in predicting the risk of the severe thoracic aortic calcification and cardiovascular and cerebrovascular events in CKD patients.Methods:It was a prospective cohort study. Patients with CKD at stage 3 to 5D in the Zhongda Hospital Affiliated to Southeast University from January 2022 to January 2023 were enrolled. Syngo.via software was used to evaluate the volume of thoracic aortic calcification, and enzyme-linked immunosorbent assay was employed to determine the level of serum NID-2. According to the volume of thoracic aortic calcification, the patients were divided into three groups: no calcification group, mild calcification group and severe calcification group. The top 25% of the patients were defined as no or mild calcification group, and the latter 75% were defined as severe calcification group. The follow-up period was one year. During the follow-up period, cardiovascular and cerebrovascular events, as well as all-cause death among the enrolled patients were recorded. Logistic regression analysis was used to screen the influencing factors of thoracic aortic calcification. Based on the results of logistic regression analysis, a nomogram prediction model was constructed. The receiver operating characteristic curve (ROC curve), calibration curve, and decision curve were employed to evaluate the discrimination, calibration and clinical practicality of the nomogram model.Results:A total of 132 patients were included, with 91 males (68.94%) and age of (56.51±16.37) years. There were 60 CKD 3-5 stage patients (non-dialysis, 45.45%) and 72 CKD 5D patients (dialysis, 54.55%). Serum ND-2 levels differed significantly among healthy individuals, dialysis patients and non-dialysis patients ( H=70.651, P<0.001). There was no statistically significant difference in serum NID-2 level between the no or mild calcification group and the severe calcification group in dialysis patients ( Z=350.00, P=0.426). The serum NID-2 level in the severe calcification group was significantly higher than that in the no or mild calcification group in non-dialysis patients ( Z=242.00, P=0.019). In non-dialysis patients, there was a statistically significant correlation between serum NID-2 level and volume of thoracic aortic calcification ( r=0.40, P<0.001). In dialysis patients, there was no statistically significant correlation between serum NID-2 level and volume of each segment of thoracic aortic calcification (all P>0.05). The univariate logistic regression analysis showed that, age, hemoglobin, serum albumin, estimated glomerular filtration rate, NID-2, hypertension, type 2 diabetes mellitus and cerebral infarction were correlated factors of thoracic aortic calcification in non-dialysis patients (all P<0.05). Multivariate logistic regression analysis showed that age ( OR=1.22, 95% CI 1.08-1.50, P=0.010) was an independent correlated factor of thoracic aortic calcification in non-dialysis patients. The above related variables of univariate logistic regression analysis were incorporated into a nomogram to construct a predictive model for severe vascular calcification in non-dialysis patients, yielding an AUC of 0.94 (95% CI 0.89-0.99) in ROC curve, with a sensitivity of 83% and a specificity of 95%. A nomogram model based on above variables for predicting cardiovascular and cerebrovascular events in non-dialysis patients demonstrated an AUC of 0.95 (95% CI 0.90-1.00) in ROC curve, with a sensitivity of 95% and a specificity of 87%. Conclusions:In non-dialysis patients, serum NID-2 level in the severe calcification group is significantly higher than that in the no or mild calcification group. The serum NID-2 is a related factor of thoracic aortic calcification and cardiovascular and cerebrovascular events in non-dialysis patients. The nomogram prediction model constructed by combining NID-2 with age, hemoglobin, serum albumin, estimated glomerular filtration rate, hypertension, type 2 diabetes mellitus and cerebral infarction has a high predictive value for the risk of thoracic aortic calcification as well as cardiovascular and cerebrovascular events in non-dialysis patients.

On plateaus,the low-oxygen and low-pressure environment is likely to lead to cognitive impairments,negatively impacting individuals newly exposed to high altitudes.This paper reviews how high-altitude environments impair cognitive functions and explores protective strategies in terms of oxygen-enriched and pressurization technologies,neuroregulation techniques,and approaches to endogenous protection.It is recommended that future research focus on personalized cognitive protection and training,the construction of integrated protection systems based on multi-technology convergence,and the investigation of long-term effectiveness and sustainability.These efforts are expected to result in more comprehensive strategies for cognitive protection and enhancement in high-altitude operations.

Objective To explore the effect of home-based pharmaceutical care for patients with stable chronic obstruc-tive pulmonary diseases(COPD)based on a digital remote management applet.Methods A total of 237 patients with stable COPD from a hospital pharmaceutical outpatient service from March 2022 to March 2023 were divided into a control group,a home visit group,and a remote management group according to the random number table method.Patients in the home visit and re-mote management groups received home-based pharmaceutical interventions such as health science popularization,medication con-sultation,medication guidance,effect evaluation of pharmacotherapy,prescription simplification,and reorganization.Such interven-tions were not provided in the control group.Regular follow-up was performed for 12 months.Results After a pharmaceutical intervention,the operating scores of the inhalation device and medication compliance scores of the home visit and remote manage-ment groups were significantly better than the control group(P＜0.05).The improvement in medication compliance was greater in the remote management group than in the home visit group(54.3％ vs.44.6％).In the three groups between enrollment and 12 months follow-up,CAT scores decreased by 0.78,6.16,and 7.30 points in the control group,home visit group,and remote manage-ment group,respectively.The mean scores of SGRQ symptom decreased by 1.19,4.24,and 6.10 points,the mean activity scores decreased by 1.65,3.56,4.80 points,the impact mean score decreased by 1.08,4.19,5.16 points,and the mean score of the total score decreased by 1.29,4.00,4.80 points in the control group,home visit group,and remote management group,respectively.The remote management group showed dia better decline in CAT score and SGRQ score than the home visit group,and there were sig-nificant differences between the two groups compared with the control group after intervention(P＜0.05).Conclusions Digital remote management of home-based pharmaceutical care mode can effectively improve medication compliance,operation accuracy of inhalation devices,clinical symptoms,and the patient quality of life.This is an effective and efficient pharmaceutical care mode for the long-term home medication management of stable COPD patients.

Objective:To explore the efficacy and safety of intravascular lithotripsy (IVL) for the treatment of calcified lesions in lower limb peripheral artery disease (PAD).Methods:A literature search was conducted on PubMed, Web of Science, Cochrane Library, and Embase, including studies related to IVL for calcified lesions in PAD published from January 2016 to December 2024. Data on patient baseline characteristics, lesion information, IVL procedural parameters, changes in vascular stenosis, and complication occurrence were extracted and included. The Methodological Index for Non-Randomized Studies (MINORS) was used to assess the quality of the included studies. The meta-analysis was performed using STATA 15.1 software. The heterogeneity of different studies was evaluated using Cochran′s Q test. The publication bias was assessed through funnel plots and Egger test.Results:A total of nine studies were included (1 983 patients, 2 387 lesions). The meta-analysis demonstrated that regarding efficacy, after IVL treatment, the average reduction in vascular stenosis was 52.1% (95% CI 45.3%-58.9%). Regarding safety, the incidence of flow-limiting dissection was only 0.6% (95% CI 0.1%-1.4%), and the perforation rate was 0.4%-0.5%, with no events of severe amputation or death. In combined treatments, the usage rate of drug-coated balloons reached 51.2%, and the stent implantation rate was 20.4%. Conclusions:IVL can effectively reduce the degree of vascular stenosis in calcified lesions and has a high safety profile. Combined treatment with drug-coated balloons can reduce the dependence on stents.

Objective To explore the time-varying pattern of potential symptoms in breast cancer patient before and after chemotherapy,and further analyze its influencing factors,aims to provide reference for clinical nursing practice.Methods 233 cases of breast cancer in a tertiary A hospital in Ningxia from June to October,2023 were selected as the research subjects.By the general information questionnaire and the Chinese version of Anderson Symptom Assessment Scale,the potential change of symptoms of breast cancer patients undergoing chemotherapy 1-3 days before the first chemotherapy(T1,233 cases)and 7-14 days after the third or fourth chemotherapy(T2,225 cases)was analyzed.Results 225 cases of breast cancer patients completed 2 surveys,and their symptom characteristics before and after chemotherapy can be divided into 2 categories:a high symptom troubled group and a low symptom troubled group.The high-symptom troubled group has strong stability,and the probability of maintaining the original group is 85.20％,while the low-symptom troubled group is more inclined to change to the high-symptom troubled group,and the transition probability is 26.60％.Logistic regression analysis showed that the mass was located on the left side,and the patients who obtained disease knowledge mainly through the Internet were more likely to change from the high symptom troubled group to the low symptom troubled group,while the patients who were employed,with unsatisfactory sleep at night,and never exercised were more likely to change from the low symptom troubled group to the high symptom troubled group.Conclusion The symptoms of breast cancer patients before and after chemotherapy are heterogeneous.Patients who are on the job,have unsatisfied sleep at night and never exercise are more likely to change from the low-symptom troubled group to the high-symptom troubled group,which suggests that medical staff should identify potential high-risk groups at an early stage,and make full use of the predictive function of symptom characteristics to carry out individualized management based on the dynamic monitoring of symptoms according to different types of population characteristics,so as to reduce the burden of symptoms and improve their quality of life.

In recent years,the incidence of childhood cancer has shown a steady upward trend.Due to the unique nature of this disease,the issue of affiliate stigma among primary caregivers of children with cancer has gradually drawn attention.Affiliate stigma not only directly affects caregivers' mental health and quality of life,but also leads to reduced social support and lower self-efficacy,thereby impacting their engagement in the caregiving process and affecting the treatment adherence and prognosis of children with cancer indirectly.This article provides a review covering 5 main areas:the conceptual definition of affiliate stigma,measurement tools,influencing factors,intervention strategies,and insights and recommendations,to provide a theoretical basis and guidance for subsequent research and the development of interventions.
