Objective: To explore the relationship between snack consumption and depressive symptoms in first year junior high school students with different left behind experiences in Yunnan Province, so as to provide a basis for improving depressive symptoms among first year junior high school students with different left behind experiences. Methods: From October to December 2022,a cluster random sampling method was used to select 8 500 first year junior high school students from 11 ethnic minority areas (Fugong County, Longling County, Longyang District, Luchun County, Mojiang County, Nanjian County, Qiaojia County, Shuangjiang County, Tengchong City, Yuanmou County, Zhenyuan County) in Yunnan Province for a questionnaire survey. The Chinese version of Depression Anxiety Stress Scale-21 was applied to assess depressive symptoms in first year junior high school students, and snack consumption was collected by employing food frequency questionnaire. The generalized linear model was used to analyze the association between first year junior high school students snack consumption and depressive symptoms, and the analysis was stratified according to left behind experience. Results: The detection rates of depressive symptoms among firstyear junior high school students with and without left behind experience were 36.25% and 26.91%, respectively. After controlling for confounding variables, the generalized linear model analysis showed that sweet snacks ( β=0.16, 95%CI =0.07-0.25), fast food ( β=0.14, 95%CI =0.04-0.23) and carbonated drinks ( β=0.09, 95%CI =0.01-0.17) of first year junior high school students with left behind experience (all P <0.05). Compared with those without such behavior, the risk of depressive symptoms was higher in consumption of fast food ( β=0.13, 95%CI =0.07-0.18) and carbonated drinks ( β=0.10, 95%CI =0.06-0.15)among first year junior high school students without left behind experience (both P <0.05). Conclusion Snack consumption among first year junior high school students in Yunnan may increase the risk of developing depressive symptoms, while first year junior high school students with left behind experience may have a greater risk of developing depressive symptoms.

Primary biliary cholangitis （PBC） is a cholestatic autoimmune liver disease characterized by the injury of small intrahepatic bile ducts， and at present， the pathogenesis of PBC remains unclear. Recent studies have shown that bile acid metabolism disorder and gut microbiota imbalance play a key role in the development and progression of PBC， and they form a complex and dynamic interaction network via the “gut-liver axis” and regulate core physiopathological processes such as immune response， metabolic homeostasis， and inflammatory response in a synergistic manner. This article systematically elaborates on the abnormal features of bile acid metabolism and gut microbiota in PBC， discusses their synergistic mechanisms in PBC， and then proposes a combined strategy of targeting bile acid receptors and modulating gut microbiota， in order to overcome the limitations of current treatment modalities and provide new insights and directions for the clinical management of PBC.

Objective:To explore the correlation between the total cholesterol/high-density lipoprotein cholesterol (TC/HDL-C) ratio during pregnancy and the onset of gestational metabolic syndrome (GMS), as well as its association with pregnancy outcomes.Methods:Clinical data of 153 pregnant women diagnosed with GMS in the third trimester admitted to Women′s Hospital of Nanjing Medical University from January 2020 to December 2022 (observation group) were collected, and data of 153 healthy pregnant women (control group) were randomly selected for a comparative study. Indicators of the two groups were observed and compared. Multiple linear regression and restricted cubic spline analysis were used to analyze the correlation between TC/HDL-C in the first and second trimesters and metabolic indicators in the third trimester and GMS risk, respectively. According to the pregnancy outcomes of GMS pregnant women with different TC/HDL-C ratios, the association between TC/HDL-C ratio and preterm birth subtypes was analyzed.Results:There were statistically significant differences between the two groups in age, gestational week, pre-pregnancy body mass index (BMI), weight gain during pregnancy, abdominal circumference in the third trimester, whether to deliver vaginally, history of preterm birth, history of cesarean section, history of abortion, neonatal birth weight, and neonatal length (all P<0.05). There were statistically significant differences in blood pressure and BMI between the two groups in the second and third trimesters (all P<0.01). In the first trimester (gestational week <14 weeks), there were statistically significant differences in fasting plasma glucose (FPG), HDL-C, and TC/HDL-C ratio between the two groups (all P<0.05). In the second trimester (gestational weeks 14-27) and third trimester (gestational week ≥28 weeks), the levels of FPG, fasting insulin (FINS), triglyceride (TG), TC, low-density lipoprotein cholesterol (LDL-C), and TC/HDL-C ratio in the observation group were higher than those in the control group, while HDL-C was lower (all P<0.05). There were statistically significant differences between the two groups in postpartum abnormal blood pressure, abnormal BMI, abnormal glucose metabolism, and abnormal lipid metabolism (all P<0.05). After adjusting for age, gestational week, and BMI, first-trimester TC/HDL-C ratio was correlated with third-trimester FPG, systolic blood pressure, diastolic blood pressure, TG, TC, and HDL-C (all P<0.05); second-trimester TC/HDL-C ratio was correlated with third-trimester FPG, FINS, systolic blood pressure, diastolic blood pressure, TG, TC, HDL-C, and LDL-C (all P<0.05), and both were linearly related to third-trimester GMS risk ( Pfor trend<0.01). The TC/HDL-C ratio was positively correlated with the preterm birth rate ( RR>1). Conclusions:An increased TC/HDL-C ratio is closely related to the occurrence of GMS, which is prone to cause preterm birth and affect fetal growth and development.

Objective:To investigate the clinical efficacy of two-point localized injection of the depressor anguli oris (DAO) muscle combined with pan-platysma microbotox injection of botulinum toxin type A for improving the aesthetic of mouth corner.Methods:A retrospective analysis was conducted on clinical data from patients who received concomitant DAO localized injection and pan-platysma microbotox of botulinum toxin type A for improving drooping mouth corners at the Facial and Neck Plastic Surgery Center and the Limb and Scar Center of Plastic Surgery Hospital, Chinese Academy of Medical Sciences, between December 2022 and June 2025. Botulinum toxin type A was reconstituted to two concentrations: 40 U/ml and 20 U/ml for the combined injection. Patients were instructed to repeatedly perform upward puckering motions to identify the trapezoidal outline of the DAO muscle. Two injection points were uniformly marked slightly medial to the midline of the DAO muscle for dual-target injection (1.5 U each at the middle one-third and lower one-third of the muscle belly). The pan-platysma microbotox for the platysma muscle extended superiorly to a line parallel and 3-4 cm above the mandibular border, innerly to 1 cm beyond the lateral edge of the DAO muscle, inferiorly to the submental area and the anterior neck region above the clavicle, and laterally to the anterior border of the sternocleidomastoid muscle. The injection dose was 0.6 U per point, with 1 cm spacing between points, administered at the superficial subcutaneous layer. Complications were recorded. At 1-month postoperatively, efficacy was evaluated using the global aesthetic improvement scale (GAIS, scores ranging from 5 to 1, representing "much worse" to "very much improved" ) and subjective patient satisfaction (categorized as very satisfied, satisfied, dissatisfied, or very dissatisfied; satisfaction rate was calculated as the percentage of patients reporting very satisfied or satisfied among the total). Patients’ willingness to receive the same treatment in the future was also surveyed. Descriptive statistics were used for analysis.Results:A total of 21 patients were included (1 male, 20 females), with a mean age of (37.1±3.2) years (range: 34-45 years). The treatment procedures were successful. Post-treatment, 4 cases experienced pain and swelling, 8 had neck ecchymosis, and 1 had temporary asymmetry in mouth corner movement, all of which resolved within 2 weeks. The follow-up period ranged from 1 to 6 months (mean: 1.4 months). At short-term follow-up (4-6 weeks after treatment), patients reported a skin "tightening" sensation in the lower face and neck region, noting significant improvement in lower facial and neck contour, sharper bilateral jawlines, and reduced neck wrinkles. Drooping mouth corners were improved. The satisfaction survey showed that 17 patients were "very satisfied" and 5 were "satisfied", resultsing in a subjective satisfaction rate of 100%. Nineteen patients (90.5%) expressed willingness to undergo repeat treatment. The mean GAIS score was 1.45±0.69, with 14 patients achieving "very much improved", 5 patients "much improved", and 2 patients "improved" .Conclusion:The combination of two-point localized injection of the DAO muscle and pan-platysma microbotox injection of botulinum toxin into the platysma muscle effectively improve the aesthetic of mouth corners and lower facial contour through synergistic middle and superficial layer treatment. This approach aligns with anatomical and physiological merits and offers advantages such as minimal invasiveness and rapid recovery, making it applicable for patients with early signs of lower facial aging.

Objective To explore the mechanism of Angong Niuhuang pill on the neurological function of rats with spontaneous intracerebral hemorrhage based on the tumor necrosis factor-α/nuclear factor-κB(TNF-α/NF-κB)signaling pathway combined with network pharmacology.Methods The targets for treatment of intracerebral hemorrhage with Angong Niuhuang pill were obtained using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP),High-Throughput Experiment and Refeence-guided Database of Traditional Chinese Medicine(HERB).Key targets were screened for Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analysis and molecular docking.Then,rats were randomly divided into normal control group,model group,Angong Niuhuang pill group(administered by gavage at 270 mg·kg-1·d-1),and the Western medicine group(intraperitoneal injection of 4 500 mg·kg-1·d-1+furosemide 1.8 mg·kg-1·d-1),the dosage administered was the equivalent dose ratio calculated based on the body surface area for humans and animals.The intracerebral hemorrhage model was replicated by the autologous heart blood caudate nucleus injection method.After modeling,the neurological function behavior scores,brain tissue water content,pathological changes of brain tissue,blood-brain barrier permeability,and protein expression levels of NF-κB p65,tumor necrosis factor receptor 1(TNFR1),inhibitor NF-κBα(IκBα)and TNF-α in brain tissue of each group were observed.Results A total of 216 intersection genes were selected.The results of GO enrichment analysis and KEGG pathway annotation analysis predicted that the TNF-α/NF-κB inflammatory signaling pathway was one of the main regulatory pathways.The animal experiment results showed that at 72 hours after modeling,compared with the model group,the neurological function score,brain tissue water content,and blood-brain barrier permeability index evans blue(EB)content of the Angong Niuhuang pill group were significantly decreased[neurological function score:1.62±0.62 vs.2.23±0.58,brain water content:(77.7±0.49)%vs.(79.9±0.04)%,EB content(μg/L):490.50±100.79 vs.1 966.20±94.81,all P<0.05];the pathological observation of brain tissue showed that Angong Niuhuang pill could reduce the pathological damage of brain tissue around the hematoma,repair the blood-brain barrier,and alleviate brain edema;the Western blotting results showed that Angong Niuhuang pill could inhibit the protein expression of TNF-α,TNFR1,and NF-κB p65 in brain tissue[NF-κB p65 protein expresion(NF-κB p65/β-actin):2.27±0.52 vs.5.40±0.26;TNFR1 protein expression(TNFR1/β-actin):1.49±0.33 vs.2.52±0.04,TNF-α protein expression(TNF-α/β-actin):1.40±0.13 vs.2.29±0.18,all P<0.05],promote the protein expression of IκB-α(IκB-α/β-actin):0.78±0.02 vs.0.32±0.00,P<0.05).Conclusion Angong Niuhuang pill may regulate the TNF-α/NF-κB signaling pathway by inhibiting the expression of TNFR1 and promoting the expression of IκB-α,exerting neuroprotective effects.

ObjectiveTo predict the in-hospital mortality risk among patients with ischemic stroke combined by dysphagia using interpretable machine learning methods, so as to provide more evidence-based support for the prognosis prediction of patients with ischemic stroke combined by dysphagia. MethodsMedical record of 308 patients diagnosed with ischemic stroke combined by dysphagia in the Medical Information Mart for Intensive Care Ⅳ (MIMIC-Ⅳ) (2.0) in the United States were retrospectively analyzed. Features of the research data were screened based on the least absolute shrinkage and selection operator, and which were randomly divided into a training set and a test set at a ratio of 7∶3. Then ten models, including logistic regression, random forest, K-nearest neighbor, linear discriminant analysis, naive bayes (NB), neural network, quadratic discriminant analysis, recursive partitioning tree, extreme gradient boosting tree, and support vector machine, etc. were constructed. The predictive effect was measured by calculating the area under the curve (AUC) of receiver operating characteristics. In addition, the calibration curve and Brier score were used to evaluate the calibration degree of the model, and the decision curve was drawn to reflect the clinical net benefit. The Shapley additive explanation method was used to analyze the interpretability of the black box model and explore the important decision-making factors. ResultsThe NB model in the test set showed better predictive ability compared with other models (AUC=0.85, 95%CI: 0.83‒0.88). After interpretability analysis, it was found that blood urea nitrogen (BUN), age, sequential organ failure assessment, bicarbonate, chloride, and hypertension were important risk factors for in-hospital mortality in patients with ischemic stroke combined by dysphagia. ConclusionThe comprehensive performance of the NB model is better than that of the other nine models in predicting the risk of in-hospital mortality in patients with ischemic stroke combined by dysphagia. The interpretability of the model can help clinicians better understand the reasons behind the results and take further reasonable intervention measures for risk factors to improve the survival probability of patients.

Baihuasheshecao(Hedyotis diffusa) is a commonly used traditional Chinese medicine derived from the whole herb of H. diffusa and has been widely utilized in folk medicine. It possesses anti-tumor, antibacterial, and anti-inflammatory properties, making it one of the frequently used herbs in TCM clinical practice. However, Shuixiancao(H. corymbosa) and Xianhuaercao(H. tenelliflora), species of the same genus, are often used as substitutes for Baihuasheshecao. To substantiate the medicinal basis of Baihuasheshecao, this study systematically reviewed classical herbal texts and modern literature, examining its nomenclature, botanical origin, harvesting, processing, properties, meridian tropism, pharmacological effects, and clinical applications. The results indicate that Baihuasheshecao was initially recorded as "Shuixiancao" in Preface to the Indexes to the Great Chinese Botany(Zhi Wu Ming Shi Tu Kao). Based on its morphological characteristics and habitat description, it was identified as H. diffusa in the Rubiaceae family. Subsequent records predominantly refer to it as Baihuasheshecao as its official name. In most regions, Baihuasheshecao is recognized as the authentic medicinal material, distinct from Shuixiancao and Xianhuaercao. Baihuasheshecao is harvested in late summer and early autumn, and the dried whole plant, including its roots, is used medicinally. The standard processing method involves cutting. It is known for its effects in clearing heat, removing toxins, reducing swelling and pain, and promoting diuresis to resolve abscesses. Initially, it was mainly used for treating appendicitis, intestinal abscesses, and venomous snake bites, and later, it became a treatment for cancer. The excavation of its clinical value followed a process in which overseas Chinese introduced the herb from Chinese folk medicine to other countries. After its unique anti-cancer effects were recognized abroad, it was reintroduced to China and gradually became a crucial TCM for cancer treatment. The findings of this study help clarify the historical and contemporary uses of Baihuasheshecao, providing literature support and a scientific basis for its rational development and precise clinical application.

OBJECTIVE: To investigate the association between long-term glycemic control and cerebral infarction risk in patients with diabetes through a large-scale cohort study. METHODS: This prospective, community-based cohort study included 12,054 patients with diabetes. From 2006 to 2012, 38,272 fasting blood glucose (FBG) measurements were obtained from these participants. FBG trajectory patterns were generated using latent mixture modelling. Cox proportional hazards models were applied to assess the subsequent risk of cerebral infarction associated with different FBG trajectory patterns. RESULTS: At baseline, the mean age of the participants was 55.2 years. Four distinct FBG trajectories were identified based on FBG concentrations and their changes over the 6-year follow-up period. After a median follow-up of 6.9 years, 786 cerebral infarction events were recorded. Different trajectory patterns were associated with significantly varied outcome risks (Log-Rank P < 0.001). Compared with the low-stability group, Hazard Ratio ( HR) adjusted for potential confounders were 1.37 for the moderate-increasing group, 1.23 for the elevated-decreasing group, and 2.08 for the elevated-stable group. CONCLUSION Sustained high FBG levels were found to play a critical role in the development of ischemic stroke among patients with diabetes. Controlling FBG levels may reduce the risk of cerebral infarction.
