Atherosclerosis （AS） is a chronic and inflammatory vascular disease. Macrophages are common immune cells and play an important role in the development of AS. In recent years， research has found that the formation of AS plaques is closely related to pathological and physiological processes such as macrophage polarization， energy metabolism， and lipid phagocytosis. This review aims to summarize the mechanism of macrophages in the development of AS， and to explore potential therapeutic methods for delaying AS by regulating macrophages， providing new ideas for the treatment and research of AS.

Objective To explore the factors that influence major adverse cardiovascular events(MACE)in atrial fibrillation(AF)patients undergoing radiofrequency ablation(RFA),as well as to compare the prognosis of patients with advanced AF to that of the general population.Methods We prospectively recruited AF patients who underwent RFA treatment at Peking University Third Hospital between January 2021 and March 2023.General patient data were collected through the hospital's inpatient system,and MACE were tracked through outpatient visits and telephone follow-ups.Patients were categorized into three age groups:Group 1(under 65 years),Group 2(65 to 75 years),and Group 3(over 75 years).In this study,MACE was defined as include cardiovascular death,all-cause death,readmission for heart failure,acute coronary syndrome(ACS),grade 2 or higher bleeding and stroke.Results A total of 431 patients were included in this study,with an average age of(66.17±12.22)years.Among these patients,259 were male(60.09％),and the mean of CHA2DS2-VASc score was(1.79±1.30).The median follow-up period was 16.0(11.3,21.3)months,during which 28(6.50％)patients experienced MACE,with ACS and stroke being the most common events.Variables were selected using LASSO regression,and a LASSO-Cox regression model was constructed.Age(HR 1.06,95％CI 1.02-1.10,P=0.006)and hypertrophic cardiomyopathy(HR 3.70,95％CI 1.27-8.68,P=0.008)were identified as independent predictors of MACE after RFA for AF.Subgroup analysis revealed that patients under 65 had significantly better prognoses compared to older AF patients(P=0.030 compared with group 2;P=0.021 compared with group 3).Conclusions Age and hypertrophic cardiomyopathy are independent risk factors for MACE in AF patients undergoing RFA.The prognosis for younger patients is better than that for older patients,while the prognosis for advanced patients is comparable to that of patients aged 65-75 years.

Excessive fat accumulation,viral infections and sustained inflammatory responses caused by non-alcoholic and alcoholic factors can contribute to liver inflammation,fibrosis and carcinogenesis,promoting the development of chronic liver disease.Gaining an in-depth understanding of the etiologic factors and underlying mechanisms that lead to chronic liver disease can help identify potential therapeutic targets for targeted therapy.Lactate,as an important substance in hepatic metabolism,has been found to be involved in the process of chronic liver disease through various pathways,and this review will provide a useful reference for the prevention and treatment of chronic liver disease.

Objective:To investigate the effect of microRNA-204-5p (miR-204-5P) on silica (SiO 2) -induced inflammatory response in macrophages and its mechanism. Methods:In September 2023, SiO 2-induced mouse macrophage (RAW264.7) model in vitro was constructed. The experiment was divided into blank control group, SiO 2 treatment group, SiO 2+ mimic transfection control group and SiO 2+ mimic transfection group. RAW264.7 cells were evenly seeded into 6-well plates and cultured for 24 hours prior to transfection. The SiO 2+mimic control group and SiO 2+mimic group were transfected with miR-204-5P mimic control and miR-204-5P mimic, respectively. After 6 hours of transfection, except for the blank control group, the other three groups were treated with SiO 2 suspension, while the blank control group received an equal volume of PBS for 24 hours of stimulation.Cell viability was detected by CCK-8 assay. RT-qPCR was used to detect the mRNA expression levels of miR-204-5P and dishevelled 3 (DVL-3) in cells. Western blot was used to detect Wnt/β-catenin pathway related proteins DVL-3, β-catenin, T cell factor 4 (TCF4) and matrix metalloproteinase 9 (MMP-9) . JAK2/STAT3 pathway related proteins Janus kinase 2 (JAK2) , signal transducer and activator of transcription 3 (STAT3) , phosphorylated JAK2 (p-JAK2) , phosphorylated STAT3 (p-STAT3) ; Inducible nitric oxide synthase (iNOS) expression level. ELISA was used to detect the expression levels of inflammatory factors interleukin-6 (IL-6) , tumor necrosis factor-α (TNF-α) and transforming growth factor-β1 (TGF-β1) in cell supernatant. The t test was used to compare the differences between the two groups, and the one-way analysis of variance was used to compare the differences among multiple groups. Results:Compared with SiO 2+ mimic transfection control group, the cell viability of SiO 2+ mimic transfection group had no significant change. The mRNA and protein levels of DVL-3 were significantly decreased ( P<0.05) . The protein expression levels of β-catenin, TCF4 and MMP-9 were significantly decreased ( P<0.05) . The protein expression levels of p-JAK2 and p-STAT3 decreased. The levels of inflammatory factors IL-6, TNF-α, and TGF-β 1 and the expression level of protein iNOS were significantly decreased ( P<0.05) . Conclusion:miR-204-5P alleviates SiO 2- induced macrophage inflammation by regulating the wnt/β-catenin pathway and JAK2/STAT3 pathway.

In 2024, a total of 27 309 cases of medication error (ME) from 484 hospitals in 27 provincial administrative regions were collected in the National Monitoring Network for Clinical Safe Medication. Among them, 279 (1.02%) were classified as grade A, 22 081 (80.86%) as grade B, 4 268 (15.63%) as grade C, 472 (1.73%) as grade D, 96 (0.35%) as grade E, 105 (0.38%) as grade F, 6 (0.02%) as grade H, and 2 (<0.01%) as grade I; no MEs of grade G occurred. Among the 27 030 patients involved in MEs of grade B to I, 15 124 (55.95%) were male and 11 906 (44.05%) were female; their ages were from 1 day to 104 years; 3 369 (12.46%) were children (<18 years old), 12 113 (44.81%) were young and middle-aged adults (≥18 to <60 years old), and 11 548 (42.72%) were elderly (≥60 years old). The top 3 contents of ME were wrong drug class (5 347 cases, 19.13%), wrong dosage (4 913 cases, 17.58%), and wrong administration frequency (3 429 cases, 12.27%). Among the 27 030 grade B-I MEs, the main person who triggered the event were physicians (18 703 cases, 69.19%) and pharmacists (6 343 cases, 23.47%). These MEs mainly occurred in clinics (11 009 cases, 40.73%), in hospital wards (7 393 cases, 27.35%), and in pharmacies (6 219 cases, 23.27%). The main persons who discovered the MEs were pharmacists (21 021 cases, 74.14%). The top 3 factors causing ME were lack of related pharmacologic knowledge (8 716 cases, 26.49%), tiredness (5 755 cases, 17.49%), and inexperienced skills (4 505 cases, 13.69%). A total of 209 patients were involved in severe MEs (grade E-I), including 133 (63.64%) males and 76 (36.36%) females, aged from 21 months to 94 years, of which 42 (20.10%) were children, 75 (35.88%) were young and middle-aged adults, and 92 (44.02%) were elderly. The top 3 diseases diagnosed in severe MEs were drug poisoning (41 cases, 19.62%), diabetes (34 cases, 16.27%), and hypertension (14 cases, 6.70%); the main person who triggered the MEs were patients and their families (135 cases, 64.59%); the MEs occurred mainly in patients′ houses (116 cases, 55.50%). Drug poisoning was mainly related to accidental ingestion by children, and MEs in patients with diabetes and hypertension were often related to issues on patient compliance. Based on the data of MEs in 2024, it was proposed to establish a better medication safety culture and improve the ME reporting situation in China, pay attention to the risks of misusing external drugs for internal use, children′s accidental ingestion and insulin-related MEs, strengthen the prevention of MEs related to look-alike sound-alike drugs, pay attention to the post administration management and the compliance education of home care for patients with chronic diseases, so as to improve the medication safety of patients in China.

Objective:To describe the prevalence of anxiety disorders and its distribution in Inner Mongolia Autonomous Region,and to explore the relevant factors of anxiety disorders.Methods:From June 2019 to Decem-ber 2019,representative multi-stage disproportionate stratified sampling procedure was used to sample in residents aged 18 and over in the Inner Mongolia Autonomous Region.All respondents were face-to-face interviewed by trained interviewers.Composite International Diagnostic Interview-3.0(CIDI-3.0)was used to diagnose anxiety disorders according to the criteria and definition of the Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition(DSM-Ⅳ).Chi-square test and multivariate logistic regression analysis were used for statistical anal-ysis.Results:Totally 12 315 people were interviewed in the survey.The weighted 12-mouth prevalence rate of any anxiety disorder was 4.64％,and the lifetime prevalence rate was 6.25％.The weighted 12-month prevalence rate of anxiety disorders was higher in female than that in male(5.38％vs.3.92％).The rate was higher in rural resi-dents than that in urban residents(5.67％vs.3.95％).The rate was higher in people with chronic diseases than that in people without chronic diseases(6.81％vs.2.29％).Logistic regression analysis showed that unmarried(OR=2.32,95％CI:1.31-4.10),separated/divorced(OR=2.49,95％CI:1.33-4.67),in debt(OR=1.55,95％CI:1.04-2.32),chronic disease(OR=2.22,95％CI:1.39-3.53),family history of anxiety disorders(OR=12.05,95％CI:8.78-16.53),poor sleep(OR=2.64,95％CI:1.97-3.54)were risk factors of occurrence of anxiety disorders,while junior high school(OR=0.65,95％CI:0.44-0.96)was protective factor of anxiety disor-ders.Conclusion:Adults with chronic diseases,poor sleep,unmarried or separated/divorced,family history of anxi-ety disorders,and financial debt are at higher risk groups of anxiety disorder in Inner Mongolia Autonomous Re-gion.

OBJECTIVE: To investigate the protective effects of stir-fried Semen Armeniacae Amarum (SAA) against aristolochic acid I (AAI)-induced nephrotoxicity and DNA adducts and elucidate the underlying mechanism involved for ensuring the safe use of Asari Radix et Rhizoma. METHODS: In vitro, HEK293T cells overexpressing Flag-tagged multidrug resistance-associated protein 3 (MRP3) were constructed by Lentiviral transduction, and inhibitory effect of top 10 common pairs of medicinal herbs with Asari Radix et Rhizoma in clinic on MRP3 activity was verified using a self-constructed fluorescence screening system. The mRNA, protein expressions, and enzyme activity levels of NAD(P)H quinone dehydrogenase 1 (NQO1) and cytochrome P450 1A2 (CYP1A2) were measured in differentiated HepaRG cells. Hepatocyte toxicity after inhibition of AAI metabolite transport was detected using cell counting kit-8 assay. In vivo, C57BL/6 mice were randomly divided into 5 groups according to a random number table, including: control (1% sodium bicarbonate), AAI (10 mg/kg), stir-fried SAA (1.75 g/kg) and AAI + stir-fried SAA (1.75 and 8.75 g/kg) groups, 6 mice in each group. After 7 days of continuous gavage administration, liver and kidney damages were assessed, and the protein expressions and enzyme activity of liver metabolic enzymes NQO1 and CYP1A2 were determined simultaneously. RESULTS: In vivo, combination of 1.75 g/kg SAA and 10 mg/kg AAI suppressed AAI-induced nephrotoxicity and reduced dA-ALI formation by 26.7%, and these detoxification effects in a dose-dependent manner (P<0.01). Mechanistically, SAA inhibited MRP3 transport in vitro, downregulated NQO1 expression in vivo, increased CYP1A2 expression and enzymatic activity in vitro and in vivo, respectively (P<0.05 or P<0.01). Notably, SAA also reduced AAI-induced hepatotoxicity throughout the detoxification process, as indicated by a 41.3% reduction in the number of liver adducts (P<0.01). CONCLUSIONS Stir-fried SAA is a novel drug candidate for the suppression of AAI-induced liver and kidney damages. The protective mechanism may be closely related to the regulation of transporters and metabolic enzymes.

Cholangiocarcinoma (CCA) is a malignant tumor originating from cholangiocytes. However, it remains unclear about the pathogenesis of this carcinoma, which may be related to multiple factors. Currently, CCA is mainly treated by surgery, chemotherapy, and radiotherapy. Among them, surgery is the only potentially curative option for CCA. Nevertheless, the high malignancy and asymptomatic nature of CCA may lead to poor treatment outcomes. It has been demonstrated that Chinese medicine (CM) plays a significant role in various antitumor applications. Meanwhile, CM exhibits fewer side effects and high availability. Moreover, the in vitro application of CM monomers has been explored in many domestic and foreign studies. This article mainly reviews the signaling pathways and molecular mechanisms of CM monomers in the treatment of CCA in recent years. These findings are expected to provide new insights into the treatment of CCA.

OBJECTIVE: To investigate the effects of acupuncture on the neurotransmitter levels and gut microbiota in a mouse model of Tourette syndrome (TS). METHODS: Thirty-six male C57/BL6 mice were randomly divided into 4 groups using a random number table method: 3,3'-iminodipropionitrile (IDPN) group, control group, acupuncture group, and tiapride group, with 9 mice in each group. In the IDPN group, acupuncture group, and tiapride group, mice received daily intraperitoneal injections of IDPN (300 mg/kg body weight) for 7 consecutive days to induce stereotyped behaviors. Subsequently, in the acupuncture intervention group, standardized acupuncture treatment was administered for 14 consecutive days to IDPN-induced TS model mice. The selected acupoints included Baihui (DU 20), Yintang (DU 29), Waiguan (SJ 5), and Zulinqi (GB 41). In the tiapride group, mice were administered tiapride (50 mg/kg body weight) via oral gavage daily for 14 consecutive days. The control group, IDPN group, and acupuncture group received the same volume of saline orally for 14 consecutive days. Stereotypic behaviors were quantified through behavioral assessments. Neurotransmitter levels, including dopamine (DA), glutamate (Glu), and aspartate (ASP) in striatal tissue were measured using enzyme-linked immunosorbent assay. Dopamine transporter (DAT) expression levels were additionally quantified through quantitative polymerase chain reaction (qPCR). Gut microbial composition was analyzed through 16S ribosomal RNA gene sequencing, while metabolic profiling was conducted using liquid chromatography-mass spectrometry (LC-MS). RESULTS: Acupuncture administration significantly attenuated stereotypic behaviors, concurrently reducing striatal levels of DA, Glu and ASP concentrations while upregulating DAT expression compared with untreated TS controls (P<0.05 or P<0.01). Comparative analysis identified significant differences in Muribaculaceae (P=0.001), Oscillospiraceae (P=0.049), Desulfovibrionaceae (P=0.001), and Marinifilaceae (P=0.014) following acupuncture intervention. Metabolomic profiling revealed alterations in 7 metabolites and 18 metabolic pathways when compared to the TS mice, which involved various amino acid metabolisms associated with DA, Glu, and ASP. CONCLUSIONS Acupuncture demonstrates significant modulatory effects on both central neurotransmitter systems and gut microbial ecology, thereby highlighting its dual therapeutic potential for TS management through gut-brain axis regulation.

The prevalence of Class III malocclusion varies among different countries and regions. The populations from Southeast Asian countries (Chinese and Malaysian) showed the highest prevalence rate of 15.8%, which can seriously affect oral function, facial appearance, and mental health. As anterior crossbite tends to worsen with growth, early orthodontic treatment can harness growth potential to normalize maxillofacial development or reduce skeletal malformation severity, thereby reducing the difficulty and shortening the treatment cycle of later-stage treatment. This is beneficial for the physical and mental growth of children. Therefore, early orthodontic treatment for Class III malocclusion is particularly important. Determining the optimal timing for early orthodontic treatment requires a comprehensive assessment of clinical manifestations, dental age, and skeletal age, and can lead to better results with less effort. Currently, standardized treatment guidelines for early orthodontic treatment of Class III malocclusion are lacking. This review provides a comprehensive summary of the etiology, clinical manifestations, classification, and early orthodontic techniques for Class III malocclusion, along with systematic discussions on selecting early treatment plans. The purpose of this expert consensus is to standardize clinical practices and improve the treatment outcomes of Class III malocclusion through early orthodontic treatment.
