ObjectiveTo review the current application status， practical challenges， and ethical issues of artificial intelligence （AI） in the field of hospice care， and to conduct a critical evaluation， with a view to offering a reference for promoting the deep integration of AI into clinical hospice care practice in China. MethodsRelevant domestic and international literature was retrieved to comprehensively analyze the application scenarios of AI in hospice care， the practical barriers encountered， and the ethical controversies， and to explore clinical optimization pathways. ResultsAI is gradually transforming the traditional service model of hospice care， with its applications primarily focusing on patient monitoring， symptom management， predictive analytics， clinical decision support， and other aspects. However， its development faced significant practical constraints and complex ethical challenges. ConclusionWhile AI holds immense potential to enhance the quality of hospice care， its application must be grounded in a core ethical framework centered on dignity， empathy， and patient autonomy. Relevant international explorations have been relatively extensive， whereas domestic studies remain in their infancy. Future research urgently warrants an in-depth exploration of the ethical and practical challenges to find localized integration pathways suited to China’s national context.

Objective To explore the clinical efficacy of Liuwei Dihuang Capsules for type 2 diabetes mellitus(T2DM)with yin deficiency syndrome and the effects on intestinal flora and inflammatory factors.Methods Totally 60 patients of T2DM with yin deficiency syndrome in Dongzhimen Hospital of Beijing University of Chinese Medicine from September 2022 to June 2023 were selected as the study objects,and were divided into control group and observation group according to the method of block randomization,with 30 cases in each group.Both groups received basic treatment.The control group was given a simulated agent of Liuwei Dihuang Capsules,while the observation group was given Liuwei Dihuang Capsules.The treatment course for both groups was 4 weeks.Clinical efficacy,blood glucose levels[fasting plasma glucose(FPG),2-hour postprandial plasma glucose(2 hPG),glycated albumin(GA)],serum insulin levels[fasting insulin(FINS)and insulin resistance index(HOMA-IR)],changes in gut microbiota,and serum inflammatory cytokine levels[interleukin(IL)-6,tumor necrosis factor(TNF)-α]of both groups were compared.Results The total effective rate of the observation group(76.67%)was better than that of the control group(50.00%)(P<0.05).Compared with before treatment,the FPG,2 hPG,GA,FINS and HOMA-IR decreased in the observation group,while the FPG,2 hPG and FINS decreased in the control group(P<0.05);after treatment,the Shannon index of the observation group increased after treatment(P<0.05),and the diversity of the microbiota increased;the abundance of the microbial communities such as Coprococcus 3,Cutibacterium,Pseudomonas,Faecalibaculum,Dubosiella and Mucispirillum significantly increased(P<0.05);the abundance of Sphingomonas,Corynebacterium 1,Ileibacterium,Ruminiclostridium and other microbiota communities significantly decreased(P<0.05).Compared with before treatment,the levels of IL-6 and TNF-α in both groups were significantly reduced after treatment(P<0.01,P<0.05).After treatment,the levels of IL-6 and TNF-α in the observation group were significantly lower than those in the control group(P<0.05).Conclusion Liuwei Dihuang Capsules can effectively reduce blood glucose levels in patients of T2DM with yin deficiency syndrome,improve insulin resistance,increase gut microbiota diversity,increase beneficial bacterial abundance,reduce harmful bacterial abundance,and alleviate inflammatory cytokine levels.

The theory of blood stasis originated from"The Yellow Emperor's Inner Canon(huang Di Nei Jing)",and the drugs used for promoting blood stasis originated from"Shennong's Classic of Materia Medica(Shen Nong Ben Cao Jing)".Finally,the medical sage Zhang Zhong-jing first put forward the name of"blood stasis"in"Synopsis of the Golden Chamber(Jin Gui Yao Lue)",and used the method of promoting blood stasis to treat various diseases,which provided ideas for the future study on the mechanism and treatment of blood stasis syndrome.Therefore,Zhang Zhong-jing was the founder of the theory of blood stasis.Moreover,the principles,methods,prescriptions and medicines which he put forward were still appropriate effectively in the clinic.On the basis of comprehensively combing the research achievements of Zhongjing's blood stasis theory,with combination with the current research hotspots,the review gives a novel understanding of the theory,method,prescription and medicine of Zhongjing's blood stasis theory from new aspects,including etiology,pathogenesis,treatment of blood stasis theory,and the active ingredients of anti-blood stasis Chinese medicines.We intend to promote the research progress of the scientific connotation of blood stasis theory,and improve the diagnosis and treatment level of clinicians in preventing and treating difficult diseases related to blood stasis syndrome through integrated summary and novel interpretation.

Objective:To observe effect of immunosuppressant cyclophosphamide on"extrapulmonary transmission"of mouse model of influenza virus pneumonia.Methods:BALB/c mice were randomly divided into normal group,virus group,cyclophospha-mide group,virus+cyclophosphamide group.Cyclophosphamide group and virus+cyclophosphamide group were intraperitoneally injected with cyclophosphamide once,24 h afterwards,virus group and virus+cyclophosphamide group were administered nasal influ-enza virus to establish influenza virus infection model,and 3,5,7 days after nasal instillation,lung index,heart index,liver index,spleen index and kidney index were measured by conventional methods;pathological changes of lung tissue,heart tissue,liver tissue,spleen tissue and kidney tissue were observed by HE staining;ELISA was used to detect levels of serum inflammatory cytokines IL-1β,IL-6,TNF-α;RT-qPCR was used to detect influenza virus load and expressions of inflammatory factors IL-1β,IL-6,TNF-α in each tissue.Results:Compared with normal group and virus group,lung index and heart index of mice in virus+cyclophosphamide group were significantly increased(P<0.05 or P<0.01);spleen index was significantly decreased(P<0.05 or P<0.01);lung tissue,heart tissue,liver tissue and spleen tissue showed different degrees of pathological damage;serum inflammatory factor IL-6 level was increased significantly(P<0.05 or P<0.01);lung tissue,heart tissue,liver tissue,spleen tissue and mRNA levels of IAV NP in kidney tissue were significantly increased(P<0.05 or P<0.01);mRNA levels of IL-1β,IL-6 and TNF-α in lung and heart tissues were significantly increased(P<0.05 or P<0.01).Conclusion:Immunosuppressant cyclophosphamide can cause damage to extrapul-monary tissues and organs in a mouse model of influenza virus pneumonia,among which heart damage is the most serious.Cyclophos-phamide is beneficial to establish model of"extrapulmonary transmission"of influenza virus pneumonia.

Objective: To analyze the trends in new diagnosis rates of HIV/AIDS cases in Huzhou City, Zhejiang Province from 2009 to 2023, so as to provide the basis for improving HIV/AIDS prevention and control strategies. Methods: Data of newly reported HIV/AIDS cases in Huzhou City from 2009 to 2023 were collected through the Chinese Disease Prevention and Control Information System. The new diagnosis rate was calculated as the ratio of newly reported HIV/AIDS cases within one year to the permanent resident population during the same period. The gender, age, and regional distribution characteristics of new diagnosis rates of HIV/AIDS cases were described. The trends were analyzed using average annual percent change (AAPC) and annual percent change (APC). Results: A total of 2 088 new HIV/AIDS cases were reported in Huzhou City from 2009 to 2023, with an average annual new diagnosis rate of 4.53/105. The new diagnosis rates showed an overall increasing trend from 2009 to 2023 (AAPC=12.745%, P<0.05), with rapid growth during 2009 to 2015 (APC=32.734%, P<0.05) but no significant trend during 2015 to 2023 (P>0.05). The average annual new diagnosis rate was significantly higher in males than in females (7.54/100 000 vs. 1.40/100 000, P<0.05). Male new diagnosis rate trend closely mirrored the overall population pattern, while females showed a continuous upward trend without clear inflection point (AAPC=12.575%, P<0.05). Age-specific analysis revealed average annual new diagnosis rates of 2.75/100 000, 6.16/100 000 and 3.83/100 000 for AIDS/HIV cases aged <25, 25-<50 and ≥50 years, respectively. The cases aged <25 years showed no significant trend (P>0.05), while the cases aged 25-<50 and ≥50 years followed patterns similar to the overall population. The average annual new diagnosis rates of HIV/AIDS cases in Wuxing District, Nanxun District, Deqing County, Changxing County and Anji County were 6.54/100 000, 3.43/100 000, 3.45/100 000, 3.56/100 000 and 4.94/100 000, respectively, showing overall upward trends (AAPC=9.672%, 27.599%, 11.800%, 18.896% and 10.254%, all P<0.05). Conclusions The new diagnosis rate of HIV/AIDS cases showed an overall upward trend in Huzhou City from 2009 to 2023. Cases are mainly concentrated among males, people aged 25-<50 years and Wuxing District, making them key targets for HIV/AIDS prevention and control.
