Programmed cell death (PCD) is characterized as a cell death pathway governed by specific gene-encoding requirements, plays crucial roles in the homeostasis and innate immunity of organisms, and serves as both a pathogenic mechanism and a therapeutic target for a variety of human diseases. Z-DNA-binding protein 1 (ZBP1) functions as a cytosolic nucleic acid sensor, utilizing its unique Zα domains to detect endogenous or exogenous nucleic acids and its receptor-interacting protein homotypic interaction motif (RHIM) domains to sense or bind specific signaling molecules, thereby exerting regulatory effects on various forms of PCD. ZBP1 is involved in apoptosis, necroptosis, pyroptosis, and PANoptosis and interacts with molecules, such as receptor-interacting protein kinase 3 (RIPK3), to influence cell fate under various pathological conditions. It plays a crucial role in regulating PCD during infections, inflammatory and neurological diseases, cancers, and other conditions, affecting disease onset and progression. Targeting ZBP1-associated PCD may represent a viable therapeutic strategy for related pathological conditions. This review comprehensively summarizes the regulatory functions of ZBP1 in PCD and its interactions with several closely associated signaling molecules and delineates the diseases linked to ZBP1-mediated PCD, along with the potential therapeutic implications of ZBP1 in these contexts. Ongoing research on ZBP1 is being refined across various disease models, and these advancements may provide novel insights for studies focusing on PCD, potentially leading to new therapeutic options for related diseases.

Objective To analyze the interactions between different structural types of volatile oil compo-nents(VOCs)and skin lipid molecules,and investigate the mechanism of volatile oil in Chi-nese materia medica(VOCMM)as penetration enhancers. Methods In this study,210 different structural types of VOCs were selected from the VOCMM penetration enhancer database,and the molecular docking experiments were conducted with three main lipid molecules of skin:ceramide 2(CER2),cholesterol(CHL),and free fatty acid(FFA).Each VOC was docked individually with each lipid molecule.Cluster analysis was used to explore the relationship between the binding energy of VOCs and their molecular struc-tures.Nine specific pathogen-free(SPF)Sprague Dawley(SD)rats were randomly divided in-to Control,Nootkatone,and 3-Butylidenephthalide groups for in vitro percutaneous experi-ments,with three rats in each group.The donor pool solutions were 3%gastrodin,3%gas-trodin+3%nootkatone,and 3%gastrodin+3%3-butylidenephthalide,respectively.The pen-etration enhancing effects of VOCs with higher binding energy were evaluated by comparing the 12-hour cumulative percutaneous absorption of gastrodin(Q12,μg/cm2). Results(i)Most of the VOCs were non-hydrogen bonded to the hydrophobic parts of CHL and FFA,and hydrogen bonded to the head group of CER2.Among them,sesquiterpene ox-ides showed the most pronounced binding affinity to CER2.The VOCs with 2-4 rings(in-cluding carbon rings,benzene rings,and heterocycles)demonstrated stronger binding affini-ty for three skin lipid molecules compared with the VOCs without intramolecular rings(P<0.01).(ii)According to the cluster analysis,most of the VOCs that bond well to CER2 had 2-3 intramolecular rings.The non-oxygenated VOCs were bonded to CER2 in a hydrophobic manner.The oxygenated VOCs were mostly bonded to CER2 by hydrogen bonding.(iii)The results of Franz diffusion cell experiment showed that the Q12 of Control group was 260.60±25.09 μg/cm2,and the transdermal absorption of gastrodin was significantly increased in Nootkatone group(Q12=5 503.00±1 080.00 μg/cm2,P<0.01).The transdermal absorption of gastrodin was also increased in 3-Butylidenephthalide group(Q12=495.40±56.98 μg/cm2,P>0.05).(iv)The type of oxygen-containing functional groups in VOCs was also an influencing factor of binding affinity to CER2. Conclusion The interactions between different types of VOCs with different structures in the VOCMM and three skin lipid molecules in the stratum corneum were investigated at the molecular level in this paper.This research provided theoretical guidance and data support for the screening of volatile oil-based penetration enhancers,and a simple and rapid method for studying the penetration-enhancing mechanism of volatile oils.

Medical and nursing staff should attach importance to their inner needs, help them overcome stress and challenges, provide them with personalized continuous care, and promote their role adaptation and reintegration into society.

ObjectiveTo investigate the factors that influence the first CD4+T lymphocyte counts in newly reported HIV-infected cases aged 50 and above in Dehong Prefecture of Yunnan Province during 2016 to 2021， and to understand the patient immune status and disease progression so as to provide scientific basis for HIV prevention and control strategies in the future. MethodsData was collected from the national HIV/AIDS information system. Multivariate logistic regression was used for the analysis of factors affecting the first CD4+T lymphocyte counts. ResultsA total of 642 cases of HIV infection were newly reported， among them， 571 cases had CD4+T lymphocyte counts and 200 cases （35.03%） had CD4+T lymphocyte counts <200 cells·μL^-1. Patients who were in the 50-59 age group， male， divorced or widowed， and less educated were more likely to have CD4+T lymphocyte counts <200 cells·μL^-1. Compared with active testing consultants， forced reeducation through labor or drug rehabilitation cases were less likely to have CD4+T lymphocyte counts <200 cells·μL^-1. ConclusionThere is no obvious upward trend in newly reported HIV infected persons aged 50 years and above in Dehong Prefecture during 2016 to 2021. However， the situation of CD4+T lymphocyte counts <200 cells·μL^-1 is still serious. Attention should be paid to the key groups： male， Chinese nationality， farmers， Han nationality， married or divorced， junior high school education or below， and heterosexual transmission. It is necessary to strengthen the intervention in people aged 50 and above and improve the detection efficiency.

ObjectiveTo understand the epidemiological characteristics and trends of sexually transmitted diseases （STDs） in Dehong Prefecture， Yunnan Province from 2010 to 2022， so as to provide a basis for the prevention and control of STDs in Dehong Prefecture. MethodsThe 2010‒2022 epidemic cards of STD cases in Dehong Prefecture were downloaded from the China Disease Control and Prevention Information System， and descriptive analysis of the incidence rate and demographic characteristics by disease type was conducted. The syphilis screening data of various populations in Dehong Prefecture between 2014 and 2022 were obtained from the National STD Control and Management Information System， and the syphilis positivity rates of key populations were calculated. ResultsA total of 18 225 STD cases were reported in Dehong Prefecture from 2010 to 2022， and the reported incidence rate increased from 17.1/10⁵ in 2010 to 172.0/10⁵ in 2022， showing an increasing trend （χ²_trend=42.9， P<0.001）. The number of reported cases of gonorrhea， syphilis， condyloma acuminatum， genital chlamydia infection， and genital herpes were 7 801 （42.8%）， 4 563 （25.0%）， 3 462 （18.8%）， 1 660 （9.1%）， and 775 （4.3%）， respectively. The majority of the reported STD cases were males （12 336 cases， 67.7%）， young adults aged 15 to <45 years （15 839 cases， 87.2%）， and farmers （9 230 cases， 50.7%）. The elderly group aged 65 years and over accounted for 10.5% of syphilis cases. Among different types of key populations， the highest syphilis positivity rate was found among men who have sex with men （10.1%）， followed by STD clinic attendees （8.1%）， and the syphilis positivity rates among clandestine prostitutes， voluntary counseling and testing population， drug addicts， and drug rehabilitation center/re-education through labor center population were 2.2%， 1.6%， 1.4%， and 1.3%， respectively. ConclusionFrom 2010 to 2022， the STD epidemic in Dehong Prefecture showed a rapidly increasing trend， with a higher incidence of gonorrhea and syphilis， and a higher syphilis positivity rate among men who have sex with men， drug addicts， clandestine prostitutes， and STD clinic patients. In the future， publicity， education and behavioral interventions for these groups should be strengthened to reduce the prevalence and transmission of STDs.

ObjectiveThis study aimed to investigate the HIV genotypic subtypes and molecular transmission clusters among men who have sex with men （MSM） with newly reported HIV infections in Dehong Dai and Jingpo Autonomous Prefecture （Dehong Prefecture）， Yunnan Province， China， between 2010 and 2019. The study aimed to identify potential high-risk transmitters and provide reference data for screening， management， and intervention of infection sources. MethodsPlasma samples from newly reported HIV-positive MSM individuals in Dehong Prefecture between 2010 and 2019 were collected. The viral pol gene fragments were amplified， sequenced， and genotyped. Genetic distances （GD） between pairwise sequences were analyzed and calculated. MEGA 7.0 and Gephi were used for phylogenetic and molecular transmission network analysis. ResultsA total of 159 newly reported HIV infections among MSM were included in the study， with successful genotyping of 100 cases. Nine HIV-1 subtypes were identified， with the most prevalent being CRF01_AE subtype （52%）， followed by CRF07_BC subtype （31%）， CRF55_01B subtype （10%）， and others （7%）. Cluster analysis revealed a total network access rate of 67%， forming three transmission clusters. CRF01_AE subtype formed two transmission clusters with 38 and 3 infected individuals， while CRF07_BC subtypes formed one transmission cluster with 26 infected individuals. The transmission network within the CRF01_AE clusters exhibited a more complex relationship. Significant differences in educational level were observed between the two main transmission clusters. ConclusionThe predominant HIV subtypes among newly reported MSM cases in Dehong Prefecture between 2010 and 2019 were CRF01_AE and CRF07_BC. Significant cultural differences are observed between the main transmission clusters. Continued monitoring of genotypic subtypes and targeted interventions within transmission clusters are warranted.

ObjectiveTo determine the characteristics， viral load and immunological status of HIV-infected persons and their spouses who became HIV-positive， and the reasons for HIV seroconversion in 55 HIV discordant couples in Dehong Dai and Jingpo Autonomous Prefecture （Dehong Prefecture）， Yunan Province. MethodsData on the 55 couples meeting the criteria of having a previously positive spouse were retrieved from the AIDS Integrated Prevention and Control Data Information System of the China Disease Control and Prevention Information System during 2015-2021. General socio-demographic information， age at diagnosis， exposure history， CD4⁺T lymphocyte count， and antiviral treatment were collected. Descriptive analysis and chi-square test were used to compare the distribution of pre-HIV-positive spouses and their HIV seroconverted spouses. ResultsA total of 55 spouses from HIV discordant couples had HIV seroconversion. Of them， 72.7% （40/55） of pre-HIV-positive spouses were husbands. The most recent CD4⁺T lymphocyte count in the pre-HIV-positive spouses was （328.31±246.27） cells·μL^-1 at the time of diagnosis of their seroconverted spouses， of which 36.3% （20/55） had a CD4⁺T lymphocyte count of less than 200 cells·μL^-1. Furthermore， of those pre-HIV-positive spouses with low CD4⁺T lymphocyte count， 45.0% （9/20） had an undetectable viral load， 15.0% （3/20） <400 copies·mL^-1， and 25.0%（5/20） ≥400 copies·mL^-1. Additionally， 16.4% （9/55） of the pre-HIV-positive spouses did not have a viral load test. The main reasons for HIV seroconversion among HIV-negative spouses in the discordant couples were poor condom use， poor compliance with antiviral therapy， and treatment discontinuation. ConclusionThe follow-up management of HIV discordant couples should be strengthened in Dehong Prefecture， especially the monitoring of viral load levels and immunological status of pre-HIV-positive spouses， to improve their compliance with antiviral therapy and reduce treatment discontinuation， which would effectively prevent and control HIV transmission between spouses.

A large spontaneous mass on the dorsal abdomen near the hip joint was found in an aged female Tupaia belangeri subsp. yaoshanensis after 5 years of routine feeding. The tumor in the diseased tree shrew was huge, with an intact surface and no ulceration; however, it caused inconvenience in movement while maintaining a good mental state. After inhalation anesthesia with isoflurane (2%-4%), the tree shrew was euthanized after the tree shrew entered deep anesthesia. Anatomical dissection of the tumor, the tumor boundary was unclear and infiltrated into surrounding tissues. HE staining showed that small focal pleomorphism and large areas of adipocytes were seen in the tumor tissue. The pleomorphic sarcoma area was mainly composed of atypical epithelioid cells with easily visible nuclear divisions. The size of the adipocytes was significantly different, and more pleomorphic adipocytes were seen. The cell volume was large, the nucleus was deeply stained and deformed, the edge was impressed, and the cytoplasm was seen with multiple vesicular lipid droplets. Immunohistochemical results showed that the tumor cells were positive for Vimentin, the small focal polymorphic adipocyte nucleus was positive for S-100, and Ki-67 exhibited a higher proportion of positivity. Combined with HE staining and immunohistochemical results, the spontaneous tumor in this tree shrew was comprehensively diagnosed as pleomorphic liposarcoma.
