The oral and maxillofacial region is a highly complex area composed of multiple tissue types and bears various critical functions of the human body. Diseases in this region pose significant diagnostic and management challenges; therefore, exploring new strategies for early diagnosis, targeted treatment, and tissue reconstruction is key to improving patient prognosis and quality of life. Extracellular vesicles are a group of heterogeneous lipid-bilayer membrane structures secreted by most cell types, including exosomes, microvesicles, and apoptotic bodies. Present in various body fluids and tissues, they act as messengers via the transfer of nucleic acids, proteins, and metabolites to recipient cells. To date, studies have revealed the different roles of extracellular vesicles in physiological or pathological processes, as well as applications in disease diagnosis, prognosis, and treatment. The importance and tissue specificity of the dental and maxillofacial tissues indicate that extracellular vesicles derived from this region are promising for further research. This paper reviews the published data on extracellular vesicles derived from cells, body fluids, and tissues in oral and maxillofacial regions, summarizes the latest advances in extracellular vesicles from extensive sources, and concludes with a focus on the current research progress and application prospects of engineered exosomes in oral science.

Nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3) is a cytosolic pattern recognition receptor that recognizes multiple pathogen-associated molecular patterns and damage-associated molecular patterns. It is a cytoplasmic immune factor that responds to cellular stress signals, and it is usually activated after infection or inflammation, forming an NLRP3 inflammasome to protect the body. Aberrant NLRP3 inflammasome activation is reportedly associated with some inflammatory diseases and metabolic diseases. Recently, there have been mounting indications that NLRP3 inflammasomes play an important role in liver injuries caused by a variety of diseases, specifically hepatic ischemia/reperfusion injury, hepatitis, and liver failure. Herein, we summarize new research pertaining to NLRP3 inflammasomes in hepatic injury, hepatitis, and liver failure. The review addresses the potential mechanisms of action of the NLRP3 inflammasome, and its regulation in these liver diseases.

Objective:To investigate the effect of mindfulness-based cognitive therapy on the sense of personal control and illness perception of young and middle-aged patients after percutaneous coronary intervention (PCI), so as to provide theoretical and practical guidance for the psychological care of patients after PCI.Methods:A randomized controlled trial was conducted. From January 2022 to December 2023, young and middle-aged patients after PCI admitted to the Department of Cardiology, Qinhuai Medical District, Eastern Theater Command General Hospital of the Chinese People′s Liberation Army were selected as the research subjects by convenient sampling method, patients were divided into the experimental group and the control group by the random number table method. The control group was given routine nursing, and the experimental group was given mindfulness-based cognitive therapy on the basis of routine nursing. The Personal Mastery Scale (PMS), Cardiac Self-Efficacy Questionnaire (CSEQ), and Brief Illness Perception Questionnaire (BIPQ) were used to evaluate personal sense of control, self-efficacy, and illness perception before and after the intervention respectively.Results:A total of 80 young and middle-aged patients after PCI were included. There were 40 cases in the control group, including 25 males and 15 females, aged (49.43 ± 5.55) years old. There were 40 cases in the experimental group, including 19 males and 21 females, aged (49.03 ± 4.19) years old. Before the intervention, there was no statistically significant difference in the PMS, CSEQ and BIPQ scores between the two groups of patients (all P>0.05). After the intervention, the PMS, CSEQ scores of the patients in the experimental group were (23.03 ± 2.54), (45.85 ± 8.16) points respectively, which were higher than (21.95 ± 2.28), (39.05 ± 8.78) points in the control group, the BIPQ score of the patients in the experimental group was(39.63 ± 8.12) points, which was lower the (45.45 ± 8.64) points in the control group, the differences were statistically significant ( t=-2.00, -3.59, 3.11, all P<0.05). Conclusions:Mindfulness-based cognitive therapy can effectively improve the sense of personal control and self-efficacy of young and middle-aged patients after PCI, reduce the sense of threat to the disease.

Objective To investigate the correlation between apathy and imaging markers in pa-tients with aCSVD.Methods A total of 143 patients diagnosed with aCSVD and hospitalized in the Department of Neurology of the First Affiliated Hospital of Baotou Medical College,Inner Mongolia University of Science and Technology from August 2023 to August 2024 were continu-ously included as the study objects.According to MAES,they were divided into an apathetic group(MAES score＞14,68 cases)and a non-apathetic group(MAES score ≤14,75 cases).The clinical data and imaging markers were compared between the two groups.Results The apathetic group had significantly older age and larger ratio of hypertension,but shorter years of education and lower MAES score than the non-apathetic group(P＜0.05,P＜0.01).The apathetic group also had notably higher Fazekas score of white matter hyperintensity(WMH),larger recent small sub-cortical infarct(RSSI),lacunar infarct(LI),and perivascular space(PVS)in the basal ganglia and the centrum semiovale,more obvious cerebral atrophy and cerebral microbleed(CMB),and high-er total imaging burden score when compared with the non-apathetic group(P＜0.01).In the aCSVD patients,the MAES score was positively correlated with WMH Fazekas score,RSSI,LI,basal ganglia PVS,centrum semiovale PVS,cerebral atrophy,CMB,and total imaging burden score(P＜0.01).WMH Fazekas score was an independent risk factor for apathy in the aCSVD patients(OR=2.218,95％CI:1.343-3.664,P=0.002).Conclusion The higher the score of ima-ging markers in patients with aCSVD,the more severe the apathy.

Prescription sequence symmetry analysis (PSSA) is one of the important methods for post-marketing pharmacovigilance based on the real-world medical prescription databases. It can be used to detect prescription cascades and mine adverse drug reaction (ADR) signals, which has been verified by many studies. PSSA shows high specificity and medium sensitivity in identifying ADR. It can quantify the correlation or risks of ADR. It is easy to use and simple in algorithm, and it has good robustness to some non time-dependent confounding factors. However, the results may be affected by some human confounding factors and data quality. This paper reviews the principle, calculation method, application scope, and precaution of PSSA by reviewing related literature on PSSA domestically and abroad, in order to provide reference for pharmacovigilance in China.

Objective:To understand the application situation and role of prescription sequence symmetry analysis (PSSA) in pharmacovigilance.Methods:The relevant databases at home and abroad were searched (up to April 30, 2024), and the original articles using PSSA as the research method were collected. The basic information of the literature (first author, publication year, country, etc.), the purpose and main content of the study, the index drugs as well as the marker drugs or medical diagnoses involved in the adverse drug reactions (ADRs) were extracted. Descriptive statistical analysis was carried out.Results:A total of 66 articles were included in the analysis. The first article was published in 1996, the number of articles published in recent years has increased significantly, and those published after 2016 accounted for 68.2% (45/66). The top 3 countries in terms of published literature quantity were the United States, Denmark, and Japan. The index drugs most commonly studied were those for the cardiovascular system and the neuropsychiatric system, in 18 and 14 articles respectively. The drugs studied in 3 or more papers were hypolipidemic drugs, antihypertensive drugs, antipsychotics, antiepileptics, proton pump inhibitors, hypoglycemic drugs and anticoagulants. The targeted ADRs/diseases most studied were those about the neuropsychiatric system (in 13 studies), followed by those about the endocrine and metabolic system (in 12 studies). The research objective in 47 articles was to explore the association between index drugs and ADRs/diseases through PSSA. Finally, the associations between 21 ADRs and index drugs were identified in 24 articles, of which 9 were new ADRs not recorded in drug instructions; benefits or potential preventive and therapeutic effects of index drugs on certain diseases were found in 7 studies. Ten studies were conducted to explore ADR information of specific drugs or detect suspicious drugs that cause specific ADRs, and some correlation signals between drugs and ADRs that previously unknown were detected. Nine studies evaluated the prescribing cascades, including the use of antitussive drugs after ACEI, the prescribing cascades related to drug-induced lower urinary tract symptoms and edema, the prescription cascades of statins, and the prescribing cascade relic.Conclusion:PSSA is a useful method for identifying potential prescribing cascades and mining ADR signals using medical prescription databases, especially suitable for the safety monitoring of long-term medication for chronic diseases and the signal detection of ADR that causal relationships are difficult to determine.

The current classification methods for traditional Chinese medicine （TCM） visceral syndrome differentiation suffer from excessive generalization， which hinders their clinical application. Based on the analysis of the pattern of "one syndrome corresponding to multiple formulas"， this paper focused on the principle of syndrome-formula correspondence， and proposed that formula-syndromes are the smallest units for refining visceral syndromes. By establishing the correspondence between formula-syndromes and visceral syndromes， this study aims to further clarify the refined categories of syndromes and their treatment patterns， providing a new perspective for the standardization and objectification of TCM syndromes.
