Objective To systematically review international research on health communication, and to provide valuable insights and reference for China's health communication research and practice. Methods This study included 693 articles published from January 2023 to April 2024 in two authoritative academic journals in the field of health communication, ^“Health Communication^” and the ^“Journal of Health Communication^”. A systematic review was conducted on the themes, theoretical foundations, research methods, and populations of international health communication research. Results The findings in this study revealed that international health communication research topics were diverse, with hotspots including social media, health information behavior, health misinformation, stigmatization, trust, and risk perception. The results showed that 34% of the articles were based on theoretical foundations, and 93.3% employed research methods, focusing on adolescents, parents, women, and other key populations. Conclusion Domestic health communication research can expand its perspective from ^“information transmission^” to ^“social interaction^”, innovate theories and methods from ^“single paradigm" to ^“multi-integration^” and shift focus from a ^“mass perspective^” to ^“targeted care^” for the health of all populations. Domestic health communication practice can delve into the localization of social media health communication practices, the comprehensive management of health misinformation, and the critical application of new technologies.

Objective To report the diagnosis of a canine distemper virus outbreak among a colony of cynomolgus monkeys at an experimental monkey farm in 2019. MethodsA total of 46 samples were collected from 21 diseased cynomolgus monkeys (exhibiting symptoms such as facial rash, skin scurf, runny nose, and diarrhea) and from one deceased monkey at an experimental monkey breeding farm in South China in late 2019, including serum, skin rash swabs, and anticoagulated whole blood, liver, lung, and skin tissues were submitted for testing. All submitted samples were tested for canine distemper virus gene fragments using real-time quantitative PCR, while immunohistochemical staining was performed to detect canine distemper virus nucleoprotein in lung tissues. The skin tissue of the deceased monkey was ground and sieved. The filtrate was inoculated into a monolayer MDCK cell line for virus isolation. Then, whole-genome sequencing was performed to identify the isolated virus. The Clustal Omega tool was used to align and analyze the homology of different Asian canine distemper virus isolates. A phylogenetic tree was constructed, followed by genetic evolutionary analysis. ResultsClinical retrospective analysis revealed that the diseased cynomolgus monkeys exhibited symptoms similar to those observed in cynomolgus monkeys infected with measles virus. Necropsy findings showed red lesions in the lungs and significant hemorrhage in the colonic mucosa. Real-time quantitative PCR detected canine distemper virus nucleic acid in the serum, skin rash swabs of the infected monkeys, and various tissue samples of the deceased monkey, all of which tested positive. Calculation based on the standard curve formula indicated the viral load was highest in the skin tissue. Immunohistochemical staining of the deceased monkey's lung tissue demonstrated aggregation of CDV nucleoprotein in alveolar epithelial cells, bronchi, and bronchioles. A CDV strain was isolated from the skin tissue of the deceased monkey. Phylogenetic analysis indicated that this strain shares the closest relationship (98.86%) with the Asian-1 type canine distemper virus strain CDV/dog/HCM/33/140816, previously identified in dogs in Vietnam. ConclusionBased on comprehensive analysis of clinical symptoms, nucleic acid detection, viral protein immunohistochemistry, and whole-genome sequencing results, the diagnosis confirms that the cynomolgus monkeys in this facility are infected with canine distemper virus. It is recommended to include canine distemper virus as a routine surveillance target in captive monkey populations. Additionally, this study provides a foundation for further research on the molecular biological characteristics of canine distemper virus.

OBJECTIVE: To investigate the therapeutic potential of octaarginine (R8)-modified essential oil from Fructus Alpiniae zerumbet (EOFAZ) lipid microspheres (EOFAZ@^R8LM) for cardiovascular therapy. METHODS: EOFAZ@^R8LM was developed by leveraging the volatilization of EOFAZ and integrating it with the oil phase of LM, followed by surface modification with cell-penetrating peptide R8 to target the site of vascular endothelial injury. The therapeutic effects of this formulation in alleviating lipopolysaccharide-induced vascular endothelial inflammation were evaluated by assessing mitochondrial membrane potential (MMP), intracellular reactive oxygen species (ROS) levels, as well as inflammatory factors interleukin-6 (IL-6) and interleukin-1β (IL-1β) levels. RESULTS: EOFAZ@^R8LM effectively delivered EOFAZ to the site of injury and specifically targeted the mitochondria in vascular endothelial cells, thereby ameliorating mitochondrial dysfunction through regulation of MMP and reduction of intracellular ROS levels. Moreover, it attenuated the expression levels of IL-6 and IL-1β, exerting protective effects on the vascular endothelium. CONCLUSION Our findings highlight the significant therapeutic potential of EOFAZ@^R8LM in cardiovascular therapy, providing valuable insights for developing novel dosage forms utilizing EOFAZ for effective treatment against cardiovascular diseases.

Cholesterol (CH) plays a crucial role in enhancing the membrane stability of drug delivery systems (DDS). However, its association with conditions such as hyperlipidemia often leads to criticism, overshadowing its influence on the biological effects of formulations. In this study, we reevaluated the delivery effect of CH using widely applied lipid microspheres (LM) as a model DDS. We conducted comprehensive investigations into the impact of CH on the distribution, cell uptake, and protein corona (PC) of LM at sites of cardiovascular inflammatory injury. The results demonstrated that moderate CH promoted the accumulation of LM at inflamed cardiac and vascular sites without exacerbating damage while partially mitigating pathological damage. Then, the slow cellular uptake rate observed for CH@LM contributed to a prolonged duration of drug efficacy. Network pharmacology and molecular docking analyses revealed that CH depended on LM and exerted its biological effects by modulating peroxisome proliferator-activated receptor gamma (PPAR-γ) expression in vascular endothelial cells and estrogen receptor alpha (ERα) protein levels in myocardial cells, thereby enhancing LM uptake at cardiovascular inflammation sites. Proteomics analysis unveiled a serum adsorption pattern for CH@LM under inflammatory conditions showing significant adsorption with CH metabolism-related apolipoprotein family members such as apolipoprotein A-V (Apoa5); this may be a major contributing factor to their prolonged circulation in vivo and explains why CH enhances the distribution of LM at cardiovascular inflammatory injury sites. It should be noted that changes in cell types and physiological environments can also influence the biological behavior of formulations. The findings enhance the conceptualization of CH and LM delivery, providing novel strategies for investigating prescription factors' bioactivity.

ObjectiveTo analyze the adverse reactions associated with the clinical use of Banxia （Rhizoma Pinelliae）- Wutou （Aconitum） in the same formula， with the aim of providing a reference for the safety of their clinical application. MethodsLiterature on the clinical application of antagonistic herbs "Banxia-Wutou" used in the same formula， published from January 1st， 2014， to June 30th， 2023， was retrieved from databases including CNKI， VIP， Wanfang， SinoMed， PubMed， Cochrane Library， and Embase. A database was established， and information related to adverse reactions was extracted， including descriptions， classifications， specific manifestations， management and outcomes， patients' primary diseases （western medicine diseases and traditional Chinese medicine diagnoses and syndromes）， and medication information （dosage， ratio， administration routes， and dosage forms）. ResultsA total of 79 researches simultaneously used antagonistic herbs Banxia-Wutou in the same formula and reported associated advers reactions. Gastrointestinal adverse reactions were the most common， with 8 studies reporting management of adverse reactions and 3 studies reporting improvement with no intervention. Among the 11 researches， the adverse reaction relieved to extant， while other 69 researches didn't report the managment of adverse reaction and its prognosis. For the primary disease in western medicine system， chronic bronchitis and chronic obstructive pulmonary disease （COPD） were most common， while gastric pain was the most common symptom in traditional Chinese medicine with spleen and kidney deficiency and spleen stomach cold deficiency being the most frequent syndromes. The most common Banxia dosage was 10 g， while for the Wutou， Fuzi （Radix Aconiti Lateralis Praeparata） was predominant with the highest dose at 15 g. The most frequent herbal combination was Banxia-fuzi， with a 1∶1 ratio. The main administration route was oral， and the primary dosage form was decoction. ConclusionGastrointestinal adverse reactions are the most common in the clinical use of Banxia-Wutou antagonistic herb combinations. Research on the safety of "Banxia-Wutou" combinations should focus on respiratory system diseases and spleen-stomach related conditions.

Objective:To investigate the effects and possible mechanisms of targeted inhibition of Polo-like kinase 1 (PLK1) on the proliferation, mitosis and apoptosis of cervical cancer cells.Methods:Logarithmically growing human cervical cancer cell lines HeLa and C-33A were selected, and cells treated with 10 and 20 nmol/L PLK1 inhibitor GSK461364 were used as different concentrations of GSK461364 groups, while cells not treated with GSK461364 were used as the control group. CCK-8 method was used to detect cell proliferation ability (represented by absorbance values at wavelength 450 nm), flow cytometry was used to detect chromosome ploidy (propidium iodide staining), mitochondrial membrane potential detected by flow cytometry was used to evaluate cell apoptosis status (JC-1 fluorescent probe, the cells where the JC-1 monomers emitting green fluorescence were located were apoptotic cells), and Western blotting was used to detect the expression levels of cell cycle and apoptosis-related proteins.Results:The results of CCK-8 method showed that the proliferation ability of HeLa cells was lower than that of the control group after 24 hours of treatment with 10 and 20 nmol/L GSK461364 and continued culture for 24, 48 and 72 hours without GSK461364. The proliferation ability of C-33A cells was lower than that of the control group after 24 hours of treatment with 10 and 20 nmol/L GSK461364 and continued culture for 48 and 72 hours without GSK461364, and the differences were statistically significant (all P < 0.05). The results of flow cytometry analysis showed that after 24 hours of treatment with GSK461364 and continued culture for 72 hours without GSK461364, the proportions of polyploid cell subpopulations in HeLa cells of the 10 and 20 nmol/L GSK461364 groups and the control group were (13.89±3.73)%, (12.30±5.49)% and (9.86±1.15)%, respectively, with no statistically significant difference ( F = 0.82, P > 0.05); the proportions of polyploid cell subpopulations in C-33A cells of the 10 and 20 nmol/L GSK461364 groups and the control group were (8.45±2.20)%, (11.06±2.53)% and (5.42±1.36)%, respectively, with statistically significant difference ( F = 5.46, P = 0.045). Among them, the proportion of polyploid cell subpopulations in the 20 nmol/L GSK461364 group was higher than that in the control group, with statistically significant differences ( t = 3.40, P = 0.027). The results of flow cytometry detection of mitochondrial membrane potential showed that after 24 hours of treatment with GSK461364 and continued culture for 72 hours without GSK461364, the proportions of apoptotic cells in HeLa cells of the control group, 10 nmol/L GSK461364 group and 20 nmol/L GSK461364 group were (3.96±2.28)%, (24.38±4.89)%, and (46.24±4.38)%, respectively, and the difference was statistically significant ( F = 83.18, P < 0.000 1), the proportion of apoptotic cells in the 10 and 20 nmol/L GSK461364 groups was higher than that in the control group, and the difference was statistically significant (both P < 0.01), and the proportion of apoptotic cells in the 20 nmol/L group was higher than that in the 10 nmol/L group ( t = 5.76, P = 0.005); the proportions of apoptotic cells in C-33A cells of the control group, 10 nmol/L GSK461364 group and 20 nmol/L GSK461364 group were (1.81±1.59)%, (5.22±1.57)% and (15.87±5.81)%, respectively, with statistically significant differences ( F = 12.49, P = 0.007), and the proportion of apoptotic cells in the 20 nmol/L group was higher than that in the 10 nmol/L group and the control group (both P < 0.05). The results of Western blotting analysis showed that after 24 hours of treatment with GSK461364 and continued culture for 72 hours without GSK461364, the relative expression levels of cleaved Caspase-9 and cleaved polyadenosine diphosphate-ribose polymerase in HeLa and C-33A cells treated with 10 and 20 nmol/L GSK461364 were higher than those in the control group, and the relative expression levels of cdc25c and phosphorylated cdc25c (Ser216) were lower than those in the control group, and the differences were statistically significant (all P < 0.05). Conclusions:Targeted inhibition of PLK1 can inhibit the proliferation activity of cervical cancer cells in vitro, induce cell mitotic cycle arrest, and promote cell apoptosis; these may be achieved by regulating cell cycle and apoptosis-related proteins.

Objective:To investigate disease characteristics of patients with psoriatic arthritis (PsA) based on the PsA cohort in West China Hospital, so as to provide a reference for clinicians in its diagnosis, treatment, and evaluation strategy formulation.Methods:A cross-sectional study was carried out, and a descriptive analysis was conducted on clinical data from PsA patients who were treated at the Department of Dermatology, West China Hospital, Sichuan University between April 2, 2020, and January 21, 2025. Demographic characteristics, clinical manifestations, laboratory and imaging findings, and treatment modalities were analyzed.Results:A total of 530 PsA patients were included, of whom 332 (62.6%) were males and 198 (37.4%) were females, with ages of 44.1 ± 12.4 years. Skin lesions preceded joint symptoms in 452 patients (85.3%), with time intervals ( M [ Q1, Q3]) of 8.0 (3.0, 15.0) years. Overweight or obesity was observed in 319 patients (60.2%), and 188 (35.5%) had comorbid fatty liver. Peripheral joint involvement was common (485 cases, 91.5%), with the proximal interphalangeal joints being most frequently affected by tenderness (172 cases, 35.5%) and swelling (119 cases, 24.5%) ; the number of enthesitis cases identified by ultrasonography (116 cases, 23.9%) was significantly higher than that by clinical examination (82 cases, 15.5%) ; axial joint involvement was observed in 258 patients (48.7%), with the sacroiliac joints most commonly affected (201 cases, 77.9%). Regarding treatment, conventional systemic drugs were predominant in the treatment of psoriasis prior to the diagnosis of PsA; after the diagnosis of PsA, the number of patients receiving targeted therapies increased to 334 (63.0%), with interleukin-17 inhibitors being the most common (140 cases, 26.4%), followed by tumor necrosis factor-α inhibitors (106 cases, 20.0%) and Janus kinase inhibitors (39 cases, 7.4%) . Conclusions:PsA predominantly affects males over 40 years old and is characterized by preceding skin lesions, delayed diagnosis, and multiple comorbidities. High-frequency ultrasound has advantages in the early detection of peripheral enthesitis. Further attention is needed for managing comorbidities such as fatty liver and obesity-related metabolic conditions.

In the realm of oral implantology, currently, there is no unanimous consensus or authoritative guideline regarding how to conduct implant restoration for cases involving oroantral communication or oroantral fistula. In these cases, the bony plate of the maxillary sinus floor is discontinuous, the oro-sinus mucosa is in communication, and a vertical alveolar bone defect exists. This paper presents a case of a patient with two oroantral communications who successfully underwent implant restoration via simple staged surgeries. Following a 2-year clinical follow-up, the implant remains in good condition, and the patient expresses satisfaction. The objective of this paper is to offer a simple, safe, and readily-promotable new approach for such cases.
