Based on spleen deficiency-phlegm dampness as the core pathogenesis of obesity， and integrating recent advances in modern medicine regarding the key role of immune inflammation in obesity， this paper proposes a multidimensional pathogenic network of "obesity-spleen deficiency-phlegm dampness-immune imbalance". Various traditional Chinese medicine （TCM） herbs that strengthen the spleen， regulate qi， and resolve phlegm and dampness can treat obesity by improving spleen-stomach transport and transformation， promoting water-damp metabolism， and regulating immune homeostasis. This highlights immune inflammation as an important entry point to elucidate the TCM concepts of "spleen deficiency-phlegm dampness" and the therapeutic principle of "strengthening the spleen and eliminating dampness to treat obesity". By systematically analyzing the intrinsic connection between "spleen deficiency generating dampness， internal accumulation of phlegm dampness" and immune dysregulation in obesity， this paper aims to provide theoretical support for TCM treatment of obesity based on dampness.

Objective: To explore the effects of personality and sleep quality with psychological distress of junior and senior high school stduents, so as to provide a reference basis for precise interventions of junior and senior high school students mental health. Methods: In October 2023, a convenience sampling method was used to select 9 034 students aged 12-17 from Shiyan City as the study subjects. The Pittsburgh Sleep Quality Index (PSQI) and Kessler Psychological Distress Scale (K10) were used to collect information on sleep quality and psychological distress of junior and senior high school stduents. Between group comparison was conducted by using t-test and Chi-square test. Generalized linear models were employed to analyze the interaction and joint effects of personality and sleep quality on psychological distress. Results: The generalized linear model analysis showed that the interaction between personality and sleep quality on psychological distress was statistically significant of junior and senior high school students(effect size=0.80, P <0.01). The general linear model analysis indicated that, after adjusting for variables such as age, gender, screen time, and daily sitting time with the extroverted and good sleep quality group as the reference, the introverted and poor sleep quality group had the largest mean difference in psychological distress scores (difference=0.51, P <0.05). When stratified by sleep quality, psychological distress scores were higher in the introverted and neutral personality groups with both poor and good sleep quality compared to the extroverted group (poor sleep quality: introverted difference=3.71, neutral difference=1.14; good sleep quality: introverted difference=2.23, neutral difference=0.57, all P < 0.05). When stratified by personality, psychological distress scores were higher in the poor sleep quality groups for introverted, neutral, and extroverted individuals compared to their good sleep quality counterparts (differences=8.66, 7.83, 7.34, all P < 0.05 ). Conclusions Personality and sleep quality have interactive and joint effects on psychological distress of junior and senior high school stduents. Personalized psychological interventions should be developed based on personality and sleep quality.

Objective To investigate the effects of Xuetong capsule on blood lipids and liver lesion in hyperlipidemic model animals. Methods Sixty ICR mice were randomly divided into six groups. The normal control group was fed with normal diet, the other groups were fed with high-fat diet to induce hyperlipidemia. After four weeks feeding, the three groups were given low, middle, and high doses of Xuetong capsules （0.5, 1.0, and 2.0 g/kg） by gavage, and the positive drug control group was given atorvastatin calcium （1.5 mg/kg） by gavage. The model group was given solvent （0.5% carboxymethyl cellulose sodium）. After treatment for 8 weeks, the body weight, organ index, blood lipids, blood glucose and liver function index were measured. The liver oil red staining was used to determine the lipid droplet content, and quantitative PCR was used to detect the expression of inflammatory factors TNF-α, IL-6, and IL-1β. Results The body weight, the weight of liver and spleen were significantly increased by high-fat diet. High-fat diet increased the organ indexes of the liver and spleen, the degree of liver oil red staining, and also significantly increased the levels of glucose, triglyceride （TG）, cholesterol （CHOL）, and low-density lipoprotein cholesterol （LDL-C） in serum. Compared with the model group, the level of TG has no significant change in low, middle and high doses groups. The level of CHOL in serum was reduced by Xuetong capsule with a dose dependent manner. There were significant difference between the model group and middle, high doses groups. The results of LDL-C were similar, the level of LDL-C was significantly reduced by middle and high doses groups [middle dose (0.55±0.21) mmol/L, high dose (0.52±0.22) mmol/L vs (0.81±0.29) mmol/L in model group, P<0.05]. Compared with the normal control, there was no significant difference in HDL-C levels between the high-fat model and each drug-treated group. Liver function showed that Xuetong capsules significantly reduced the degree of liver oil red staining and decreased the level of alanine aminotransferase （ALT） induced by high-fat diet. The body weight, the weight and organ indexes of liver and spleen were significantly reduced by positive drug control group. The levels of CHOL, LDL-C, and TG, and the degree of liver oil red staining were also significantly reduced in positive drug control group. Further studies have shown that high dose of Xuetong capsules significantly reduced the expression of TNF-α and IL-6 induced by high-fat diet （P<0.05）, while the reduction of IL-1β was not so significant （P>0.05）. Conclusion Xuetong capsules significantly reduced the body weight of animals with high fat, liver size, fat deposition, inflammatory damage and also significantly reduced blood lipid CHOL and LDL-C levels and transaminase elevation. The above effects may be related to Xuetong capsules reducing the expression of inflammatory factors such as TNF-α and IL-6 in the liver.

Objective: To evaluate oral health status and knowledge, attitude and practice (KAP) among third grade primary school students after the implementation of the Comprehensive Intervention Project for Childhood Oral Diseases in Guizhou Province, so as to provide evidence for program optimization. Methods: Using a multistage cluster sampling method, oral examinations and questionnaire surveys were conducted among third grade primary school students in schools covered by the Comprehensive Intervention Project for Childhood Oral Diseases in Guizhou Province (intervention group, n =1 030) and schools not covered by the program (control group， n =1 130) in November 2023. A follow up survey was conducted one year after the project s implementation (December 2024) to evaluate the differences in oral health status and KAP between the two groups. The t-test and χ 2 test were used to compare means and rates, respectively. Results: One year after implementation, the permanent caries prevalence, caries filling ratio, mean dmft/DMFT, and mean simplified debris index in the intervention group were 33.3%, 22.3 %, 3.44±3.10, 0.77±0.56, which were all better than those in the control group (39.8%, 17.3%, 3.89±2.85, and 0.87± 0.63 ) ( χ 2/ t =9.87, 8.78, -2.59, -3.91,all P <0.05). After intervention, the levels of oral health knowledge, attitude and behaviors in the intervention group were better than those in the control group ( Z =7.69, 2.35, 2.10, all P <0.05). Except for the item "fluoride has no protective effect on teeth", the correct response rates of other oral health knowledge items in the intervention group were higher than those in the control group ( χ 2=3.92-163.94, all P <0.05). The reported rates of tooth brushing related behaviors and sugary beverage consumption were higher in the intervention group than in the control group ( χ 2=4.02-11.42，all P <0.05). Conclusions The Comprehensive Intervention Project for Childhood Oral Diseases improves children s oral health status, oral health knowledge, and some oral health behaviors, but has limited effects on some behaviors and oral health attitudes. Future efforts should focus on the factors influencing the transformation of children s oral health attitudes and behaviors, along with strengthening long term follow up evaluations.

AIM: To investigate the decentration of the treatment zone(TZ)and the early impact on corneal higher-order aberrations(HOAs)induced by orthokeratology(OK)lenses fitted with digital corneal topography.METHODS: A retrospective longitudinal clinical study was conducted on 28 patients(28 right eyes)who were digitally fitted with OK lenses at the Laser Vision Center of Xi'an No.1 Hospital since 2023. Longitudinal measurements were taken at baseline, 1 wk, 1 and 3 mo post-treatment to assess changes in TZ diameter, decentration magnitude and direction. Furthermore, changes in corneal HOAs were observed, and correlations of decentration with each HOAs were also analyzed.RESULTS: The mean age of patients was 10.29±2.00 years, with 15 males and 13 females, and the average baseline spherical equivalent was -2.92±0.94 D. The average TZ diameters at 1 wk, 1, and 3 mo were 3.64±0.58, 3.83±0.57, and 3.69±0.55 mm, respectively, with no statistically significant differences between 1 wk and 3 mo. Horizontal decentration values were -0.43±0.28, -0.38±0.33, and -0.31±0.37 mm after wearing lenses for 1 wk, 1 and 3 mo, respectively, while vertical decentration values were -0.33±0.20, -0.33±0.23, and -0.36±0.23 mm across the same time points. The TZ consistently decentered inferotemporally, and changes in both horizontal and vertical decentration over time were not statistically significant(Fhorizontal=1.416, Phorizontal=0.252; Fvertical=0.126, Pvertical=0.882). Significant increases in total corneal HOAs, coma, and spherical aberration were observed at 5 mm optical zone post-wear(F=45.695, 33.401, and 45.091, all P<0.001). Vertical decentration at 1 wk and 1 mo was negatively correlated with total HOAs and coma(all P<0.05), while horizontal decentration at 3 mo showed a weak negative correlation with spherical aberration(P=0.037).CONCLUSION: Digitally-fitted OK lenses achieved stable TZ diameter by 1 wk post-wear, with minor inferotemporal decentration. Early post-wear corneal total HOAs, coma and sphercal aberration increased significantly, and vertical downward decentration was associated with elevated total HOAs and coma. However, correlations between decentration and HOAs weakened by 3 mo.

AIM: To explore the efficacy of internal limiting membrane(ILM)flap technique and simple ILM peeling in the treatment of idiopathic macular hole(IMH)and related influencing factors.METHODS: A retrospective cohort study was conducted on totally 32 patients(35 eyes)with IMH who received surgery at our department from January 2023 to November 2024. All the patients simultaneously received phacoemulsification combined with intraocular lens implantation, and they were divided into study group(19 eyes)and control group(16 eyes), with ILM flap technique and simple ILM peeling received in the two groups, respectively. The closure situation of macular hole, best corrected vision acuity(BCVA), and macular structure were observed in the two groups of patients. Furthermore, the correlation of BCVA and healing type of macular hole at the last time of follow-up with each parameter was analyzed.RESULTS: There was no statistical difference between the two groups of patients in preoperative general characteristics(all P>0.05). At the last time of follow-up, the macular hole was heeled in both groups, with 7 eyes of U-shaped heeling, 6 eyes of V-shaped heeling, and 6 eyes of irregular heeling in the study group, and with 13 eyes of U-shaped of heeling, 1 eye of V-shaped heeling and 2 eyes of irregular heeling in the control group(χ2=7.167, P=0.028). The postoperative BCVA was better than preoperative level(all P<0.05), there were no statistical significant differences between the two groups of patients in macular choroidal thickness before and after surgery(P>0.05), but the macular retinal thickness of the study group was thinner than that of the control group(168.11±92.11 vs 235.56±92.18 μm, P=0.03). Pearson correlation analysis indicated that BCVA at the last time of follow-up was positively correlated with the preoperative minimum diameter(r=0.476, P<0.05)and the diameter hole index(r=0.361, P<0.05), and negatively correlated with traction hole index(r=-0.364, P=0.031); Keendall correlation analysis showed that the postoperative closure types positively correlated with the basal diameter(τ=0.296, P=0.029), minimum diameter(τ=0.366, P=0.007), and visual acuity at the last time of follow-up(τ=0.412, P=0.003), while negatively correlated with macular hole index(τ=-0.415, P=0.002)and traction hole index(τ=-0.511, P<0.01). During the follow-up period, neither group of patients experienced postoperative complications.CONCLUSION: Both ILM flap technique and simple ILM peeling are safe and effective in treating IMH. As the smaller the basal diameter and minimum diameter of the macular hole, the larger the macular hole index and traction hole index, the probability of U-shaped heeling after surgery is greater and the visual acuity is better.

Cancer is a serious global health problem and a major cause of human death. Conventional cancer treatments often run the risk of impairing vital organ functions. Anticancer peptides (ACPs) are considered to be one of the most promising therapeutic agents against common human cancers due to their small sizes, high specificity, and low toxicity. Since ACP recognition is highly limited to the laboratory, expensive, and time-consuming, we proposed pLM4ACP, a model for predicting ACPs based on machine learning and protein language models. In this model, the protein language model ProtT5 was used to extract the features of ACPs, and the extracted features were input into the support vector machine (SVM) classification algorithm for optimization and performance evaluation. The model showcased significantly higher accuracy than other methods, with the overall accuracy of 0.763, F1-score of 0.767, Matthews correlation coefficient of 0.527, and area under the curve of 0.827 on the independent test set. This study constructs an efficient anticancer peptide prediction model based on protein language models, further advancing the application of artificial intelligence in the biomedical field and promoting the development of precision medicine and computational biology.

Objective: To explore the intra class transmission pattern of acute hemorrhagic conjunctivitis (AHC) among students, so as to provide a basis for formulating precise prevention and control strategies. Methods: The data of AHC students in 2023 was obtained from the teacher-student health information module of the "Xiamen i-Education" platform. Taking the onset date from January 1st to December 31st, 2023 as the search criteria, the epidemiological data of confirmed AHC cases among students in the whole city in 2023 was collected. And the Knox test method was employed to quantify cluster risk at the class level. Subgroup comparisons were conducted to examine differences in cluster risk between academic stages and gender combinations. Cross analysis was performed to investigate the interactive effects of two characteristics on cluster risk. Results: In 2023, 708 cases of AHC students were reported in Xiamen, among which 54 class clustered outbreaks were identified. These outbreaks accounted for 40.54% of total cases. Among them, the incidence of class clustered outbreaks with male first onset cases was higher than that with female first onset cases ( χ 2=4.55, P <0.05). The class cluster risk was at a relatively high level within the incubation period (0-2 d) after AHC onset ( RR =4.61-6.43, P <0.05). Subgroup analysis revealed that female-female case pairs had a higher class cluster risk ( RR = 4.81- 10.29) compared to other gender combinations ( P <0.05). Primary school case pairs showed a higher risk ( RR =4.60-6.77) than middle school case pairs ( RR =3.85-4.57) (both P <0.05). Cross analysis indicated that primary school and female-female combinations had a higher risk ( RR =4.70-11.24) than other combinations, while middle school and male-female combinations showed a positive interaction ( RR =3.68-6.68)(both P <0.05). Conclusions AHC infection among students is primarily transmitted within classes. Gender and educational stage are key demographic factors influencing class cluster transmission risks. Transmission risks should be assessed by analyzing population characteristics and contact patterns, and targeted interventions should be implemented.

Objective:To discuss the differential expression of microRNA(miR)-125a-5p in peripheral blood mononuclear cells(PBMCs)of the patients with mycobacterium tuberculosis(MTB)infection and its effect on macrophage polarization,and to clarify its clinical significance.Methods:A total of 40 patients with active tuberculosis(ATB)(ATB group),35 patients with latent tuberculosis infection(LTBI)(LTBI group),and 40 healthy physical examinees(control group)clinically diagnosed from July 2022 to June 2023 were selected.The fasting blood samples of the subjects in three groups were collected next morning after 12 h of fasting,and then serum was separated.Enzyme-linked immunosorbent assay(ELISA)method was used to detect the levels of inflammatory factors in the serum of the subjects in various groups.Simultaneously,the PBMCs were extracted from the subjects in various groups;flow cytometry was used to detect the expression levels of CD80 and CD206 proteins in the PBMCs of the subjects in various groups;real-time fluorescence quantitative PCR(RT-qPCR)method was used to detect the expression levels of microRNA(miR)-125a-5p and interleukin-6(IL-6)mRNA in PBMCs of the subjects in various groups.Results:There were no statistically significant differences in the general information of the subjects among three groups(P>0.05).Compared with control group,the erythrocyte sedimentation rate(ESR),percentages of monocytes(MONO),tumor necrosis factor-α(TNF-α)levels,and interleukin-10(IL-10)levels in serum of the patients in ATB group and LTBI group were significantly increased(P<0.05),and the percentages of lymphocytes(LY)were significantly decreased(P<0.05);compared with ATB group,the ESR and level of IL-10 in serum of the patients in LTBI group were significantly decreased(P<0.05),and the percentage of LY was significantly increased(P<0.05);there were statistically significant differences in the counts of white blood cell(WBC)of the subjects among various groups(P>0.05).The flow cytometry results showed that compared with control group,the expression levels of CD80 and CD206 proteins in PBMCs of the patients in ATB group and LTBI group were significantly increased(P<0.05).Compared with ATB group,the expression level of CD206 protein in the PBMCs of the patients in LTBI group was significantly increased(P<0.05),and the expression level of CD80 protein was significantly decreased(P<0.05).The RT-qPCR results showed that compared with control group,the expression levels of miR-125a-5p and IL-6 mRNA in the PBMCs of the patients in ATB group and LTBI group were significantly increased(P<0.05);compared with ATB group,the expression levels of miR-125a-5p and IL-6 mRNA in PBMCs of the patients in LTBI group were significantly increased(P<0.05).The correlation analysis results showed that the miR-125a-5p expression level was positively correlated with the TNF-α level and IL-6 mRNA expression level(r=0.406,P<0.05;r=0.351,P<0.05),and negatively correlated with the IL-10 level(r=-0.368,P<0.05).The area under the receiver operating characteristic(ROC)curve(AUC)value of miR-125a-5p expression level for diagnosing LTBI patients was 0.89(P<0.01),with a sensitivity of 0.85 and a specificity of 0.88.Conclusion:The expression level of miR-125a-5p in PBMCs of the patients in LTBI group is significantly increased,and it can affect the macrophage polarization to M1,promote the inflammatory response process of macrophages and participate in the occurrence and development of pulmonary tuberculosis.
