Objective To analyze the epidemiological characteristics and incidence trend of mumps in Nantong City from 2016 to 2023, and to provide a basis for scientific prevention and control. Methods Descriptive statistical analysis was conducted on monthly mumps incidence data in Nantong City from 2016 to 2023, and a SARIMA model was constructed to predict the incidence trend. Results A total of 3 928 mumps cases were reported in Nantong City from 2016 to 2023, with an average annual incidence rate of 6.36/100 000. Cases predominantly occurred during April–July and September–December, showing seasonal peaks. The male-to-female ratio was 1.43:1. The cases were concentrated in individuals aged ≤15 years (85.57%), primarily students, children in childcare settings, and scattered children (88.31%). The optimal model constructed by the SPSS Expert Modeler was SARIMA(1,0,0)(0,1,1)₁₂, predicting an epidemic peak of mumps in Nantong City from September to November in the second half of 2024. Conclusion From 2016 to 2023, mumps incidence in Nantong City has shown an overall downward trend with a seasonal bimodal distribution. Males had higher incidence rates than females, and cases were predominantly students, kindergartens and scattered children, highlighting the need to strengthen mumps prevention in schools and childcare institutions. The SARIMA model is suitable for short to medium term prediction of mumps in Nantong City. A minor peak is predicted to occur in the second half of 2024 (September–November). It is necessary to strengthen the epidemic surveillance of mumps and vaccination of age-eligible children.

In recent years, the rising prevalence of obesity and its associated metabolic syndromes has emerged as a critical global public health concern. Sustained weight loss exceeding 10% of total body weight has been shown to ameliorate obesity-related comorbidities, including type 2 diabetes mellitus, hypertension, and hepatic steatosis. Recently, the potential of brown adipose tissue (BAT) to improve metabolism has garnered significant attention. However, evidence regarding weight loss therapies that promote BAT activation remains limited in preclinical models and is even scarcer in clinical studies, partly due to the paucity of appropriate BAT assessment techniques. This review aims to explore the potential impact of various weight loss therapies on BAT, with the goal of providing novel insights and strategies for the treatment of obesity.

ObjectiveTo observe the effects of Dihuang Yinzi （DY） on motor dysfunction in rats with advanced Parkinson's disease （PD） and to investigate the mechanisms by which DY improves advanced PD symptoms through the "gut microbiota-short-chain fatty acids （SCFAs）-inflammation-neuroprotection pathway". MethodsAn advanced PD rat model was induced by rotenone. Rats were divided into a normal group， model group， positive drug group （levodopa， 50 mg·kg^-1）， and DY low-， medium-， and high-dose groups （5.2， 10.4， 20.8 g·kg^-1）. After 7 days of administration， motor function was evaluated using the open-field， pole-climbing， and inclined plate tests. Hematoxylin-eosin （HE） staining was used to observe pathological changes in the substantia nigra and colon， and immunohistochemistry was performed to detect α-Synuclein （α-Syn） and tyrosine hydroxylase （TH） expression in the substantia nigra. Enzyme-linked immunosorbent assay （ELISA） was used to measure levels of dopamine （DA）， 5-hydroxytryptamine （5-HT）， 3，4-dihydroxyphenylacetic acid （DOPAC）， Levodopa， homovanillic acid （HVA）， tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， and interleukin-1β （IL-1β）. Western blot analysis was used to detect the expression of zonula occludens-1 （ZO-1） and occludin. Gut microbiota diversity was analyzed by 16S rRNA sequencing， and gas chromatography （GC） was used to determine the content of SCFAs in colonic contents. ResultsCompared with the normal group， the model group showed significantly decreased movement speed and distance in the open-field test， prolonged pole-climbing time， and reduced retention angle on the inclined plate （P<0.01）， accompanied by increased α-Syn expression （P<0.01） and decreased TH expression （P<0.01） in the brain. Compared with the model group， all DY dose groups improved motor dysfunction in advanced PD rats to varying degrees （P<0.05， P<0.01） and alleviated pathological damage in the brain and colon. High-dose DY significantly reduced α-Syn aggregation in the substantia nigra （P<0.01） and increased TH expression （P<0.01）. ELISA and Western blot results showed that， compared with the normal group， the model group exhibited decreased levels of DA， 5-HT， DOPAC， Levodopa， and HVA in the striatum （P<0.01）， increased levels of TNF-α， IL-6， and IL-1β in the colon and striatum （P<0.01）， and significantly reduced expression of ZO-1 （P<0.05） and occludin in the colon （P<0.01）. Compared with the model group， all DY dose groups increased the levels of DA， 5-HT， DOPAC， Levodopa， and HVA in the striatum to varying degrees （P<0.05， P<0.01）. In the high-dose DY group， the levels of TNF-α， IL-6， and IL-1β in the colon and striatum were reduced （P<0.01）， while the expression of ZO-1 （P<0.05） and occludin in the intestine was increased. The 16S rRNA sequencing results indicated that the relative abundances of Actinobacteriota， Enterobacteriaceae， and Erysipelotrichaceae were increased in the model group， whereas the relative abundances of Bacteroidota， class Clostridia， Lachnospiraceae， and Akkermansia muciniphila were decreased. These changes were effectively reversed after high-dose DY intervention. GC analysis showed that the content of SCFAs in the colonic contents of rats in the model group was decreased （P<0.05， P<0.01）， while after high-dose DY intervention， the levels of acetate， propionate， isobutyrate， and butyrate were significantly increased （P<0.05， P<0.01）. ConclusionDY may exert therapeutic effects in advanced PD by regulating the gut microbiota-SCFAs-inflammation pathway.

There are practical and cost-effective opportunities for the prevention and early intervention of periodontal disease, a common oral condition. Depression and anxiety represent major global mental health challenges, and they are characterized by high prevalence rates and an elevated suicide risk. Their clinical management is complicated by extended treatment timelines and substantial healthcare costs. Accumulating evidence demonstrates a statistically significant bidirectional association between periodontal disease and depression/anxiety disorders. However, established clinical pathways integrating these conditions remain lacking. This review presents a comprehensive analysis of current research examining the relationship between periodontal disease and mood disorders, specifically depression and anxiety. This study explored the bidirectional mechanisms within the microbiota-oral-brain axis, which includes both periodontal disease inducing neuroinflammation through pro-inflammatory factors, such as interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) activating the TLR-4/NF-κB signaling pathway, and depression and anxiety leading to “glucocorticoid resistance” through hypothalamic-pituitary-adrenal (HPA) axis dysregulation, thus causing dual immune dysfunction that exacerbates periodontal tissue destruction, as well as the mechanisms by which biological, psychological, and social factors contribute to the bidirectional association between periodontal disease and depression/anxiety. We propose implementing bidirectional referral protocols between dental and psychiatric services in clinical practice, incorporating mental health screening tools, such as Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7(GAD-7), for patients with moderate-to-severe periodontal disease, and incorporating periodontal examination into routine assessment during psychiatric services. This multidisciplinary approach aims to break the vicious circle between these conditions and provide clinicians with pragmatic intervention strategies.

Traditional Chinese medicine （TCM） therapy has unique clinical advantages in the treatment of atrial fibrillation， mainly reflected in five aspects， improving quality of life， enabling early diagnosis and treatment， promoting cardiac rehabilitation， making up for the limitations of Western medicine， and improving the success rate of catheter ablation. However， there is insufficient evidence in current clinical research. Based on the current status of TCM research in the treatment of atrial fibrillation， it is suggested that future studies should focus on standardized research on syndrome differentiation and classification. This can be achieved through clinical epidemiological surveys， expert consensus， and other methods to establish a unified syndrome differentiation and classification standard for atrial fibrillation. Clinical efficacy evaluation indicators should be standardized， and core outcome measures for clinical research on TCM treatment of atrial fibrillation should be developed through systematic reviews， patient interviews， and other methods. Additionally， clinical research design， implementation， and data management should be improved. By leveraging modern information technologies such as artificial intelligence， the scientific and standardized nature of TCM intervention research on atrial fibrillation can be enhanced， ultimately improving the quality of research.

ObjectiveTo observe the effect of Yifei Jianpi prescription on the of signal transducer and activator of transcription protein 1 （STAT1）/interferon regulatory factor 3 （IRF3） signaling pathway in a pneumonia model induced by lipopolysaccharide （LPS） and to explore the mechanism of Yifei Jianpi prescription in improving lung immune and inflammatory responses. MethodsSixty male SPF SD rats were used in this study. Ten rats were randomly assigned to the normal control group， and the remaining 50 were instilled with LPS in the trachea to establish a pneumonia model. After successful modeling， the rats were randomly divided into the model group， dexamethasone group （0.5 mg·kg^-1）， and Yifei Jianpi prescription high-dose （12 mg·kg^-1）， medium-dose （6 mg·kg^-1）， and low-dose （3 mg·kg^-1） groups， with 10 rats in each group. Treatment was administered once daily， and the normal control and model groups received the same volume of normal saline. After 14 days， flow cytometry was used to detect the classification of whole blood lymphocytes. Enzyme-linked immunosorbent assay （ELISA） was used to measure serum levels of immunoglobulin G （IgG）， immunoglobulin A （IgA）， immunoglobulin M （IgM）， and the content of tumor necrosis factor-α （TNF-α）， interleukin-8 （IL-8）， interleukin-6 （IL-6）， and interleukin-10 （IL-10） in alveolar lavage fluid （BALF）. Hematoxylin-eosin （HE） staining was used to observe lung tissue pathology and score the damage. Thymus weight， spleen weight， and wet-to-dry weight ratio （W/D） were recorded. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of STAT1， IRF3， IL-6， and interferon-alpha （IFN-α） in lung tissues， while Western blot was performed to assess the protein expression of STAT1， IRF3， IL-6， and IFN-α. ResultsCompared with the normal control group， the model group showed significantly increased proportion of B lymphocytes in peripheral blood， decreased proportions of NK cells and CD4⁺/CD8⁺ （P<0.05， P<0.01）， decreased serum levels of IgG and IgA， significantly increased IgM levels （P<0.01）， significantly elevated content of TNF-α， IL-6， and IL-8 in BALF， and significantly decreased IL-10 levels （P<0.01）. Lung tissue damage was evident， with significant increases in thymus and spleen weights and a higher W/D ratio （P<0.01）. The mRNA and protein expression of STAT1， IRF3， IFN-α， and IL-6 in lung tissues was significantly upregulated （P<0.05，P<0.01）. Compared with the model group， the Yifei Jianpi prescription groups showed significantly reduced proportions of B lymphocytes in peripheral blood， increased proportions of NK cells and CD4⁺/CD8⁺ ratios （P<0.05， P<0.01）， significantly increased serum levels of IgG and IgA， significantly decreased IgM levels （P<0.05， P<0.01）， significantly reduced levels of TNF-α， IL-6， and IL-8 in BALF， and significantly increased IL-10 levels （P<0.01）. Lung tissue damage was alleviated， thymus and spleen weights were significantly reduced， and the W/D ratio was markedly decreased （P<0.01）. The mRNA and protein expression of STAT1， IRF3， IFN-α， and IL-6 in lung tissues was significantly downregulated （P<0.05， P<0.01）. ConclusionYifei Jianpi prescription can alleviate lung tissue damage and improve immune and inflammatory responses in LPS-induced pneumonia rats. The mechanism may be related to the inhibition of STAT1/IRF3 signaling pathway activation.

Objective:To explore the application of near-infrared spectroscopy monitoring in the diagnosis of necrotizing enterocolitis (NEC) in extremely/very low birth weight infants.Methods:Extremely/very low birth weight infants suspected of having NEC who were hospitalized in the Neonatal Intensive Care Unit of Guangzhou Women and Children′s Medical Center from September 2019 to November 2021 were selected as the research subjects. The regional intestinal oxygen saturation (rintSO 2) and regional cerebral oxygen saturation (rcSO 2) of the children within 72 hours after the onset were monitored by near-infrared spectrometer. The mean values of rintSO 2 and rcSO 2, intestinal fractional tissue oxygen extraction (intFTOE), and splanchnic-cerebral oxygenation ratio (SCOR) during the monitoring period were calculated. According to whether NEC was diagnosed or not, the patients were divided into the non-NEC group and the NEC group. The NEC group was further divided into the common NEC group and the severe NEC group. The rintSO 2, rcSO 2, intFTOE and SCOR of each group were compared. Results:A total of 78 cases were included, including 50 cases in the non-NEC group and 28 cases in the NEC group. Among them, there were 17 cases in the common NEC group and 11 cases in the severe NEC group. The rcSO 2 in the NEC group was lower than that in the non-NEC group (65.2±6.1 vs 73.2±7.0), and the SCOR was higher than that in the non-NEC group (0.88±0.05 vs 0.81±0.07), and the differences were statistically significant (all P<0.05). There was no statistically significant difference in rintSO 2 and intFTOE between the two groups (all P>0.05). Both rintSO 2 and rcSO 2 in the severe NEC group were lower than those in the common NEC group [(52.0±4.6 vs 61.2±5.0) and (60.3±3.8 vs 68.3±5.0)], and intFTOE was higher than that in the common NEC group (0.46±0.05 vs 0.36±0.06). The differences were all statistically significant (all P<0.05). There was no statistically significant difference in SCOR between the two groups (all P>0.05). Conclusions:The monitoring values of near-infrared spectroscopy are correlated with the incidence of NEC in extremely/very low birth weight infants. Lower rcSO 2 and higher SCOR are helpful for identifying NEC, while lower rintSO 2, rcSO 2 and higher intFTOE are helpful for identifying severe NEC.

Objective:To explore the implementation effectiveness of clinical faculty teaching qualification and admission assessment program based on Miller's competency model.Methods:Action research method was adopted in combination with quantitative and qualitative analysis. The assessment scores were analyzed. Semi-structured interviews were conducted with 15 clinical teachers who participated in the assessment. Interview data were analyzed and themes were extracted based on the three-level coding method of qualitative research. The statistical functions in Excel were used to analyze the scores of six teaching components such as written tests, lesson plans, and presentations. Categorical data were expressed as frequency and percentage.Results:A total of 93.07% (188/202) of teachers passed the assessment and obtained teaching qualification certificates for clinical teaching in all relevant components. Qualitative analysis identified three main themes. The first theme was that teaching qualification and admission assessment enhanced teachers' understanding of clinical teaching standards and teacher/teaching community. The second theme was that teaching qualification and admission assessment provided clinical teachers with scenario demonstration of independent learning, peer communication, and teaching feedback and reflection. The third theme was the need for further strengthening of pre-assessment training.Conclusions:Teaching qualification and admission assessment contributes to the in-depth understanding of clinical teaching standards among clinical faculty and promotes the construction of teaching communities, thereby laying a foundation for enhancing the teaching capabilities of clinical teachers.
