Objective:
To explore the association of vegetables and fruits intake with depressive symptoms among multi ethnic first year junior high school students in Yunnan Province, so as to provide data support for preventing and reducing depressive symptoms among first year junior high school students.
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 in Yunnan Province (Fugong County, Longling County, Longyang District, Luchun County, Mojiang County, Nanjian County, Qiaojia County, Shuangjiang County, Tengchong City, Yuanmou County, Zhenyuan County), to investigate with a questionnaire. The Dietary Frequency Questionnaire was used to collect dietary behavior datas, and the Chinese version of Depression Anxiety Stress Scale-21 (DASS-21) was used to assess depressive symptoms. The generalized linear model was used to analyze the association of vegetable and fruit intake with depressive symptoms in students, and stratified analysis was performed according to ethnicity.
Results:
The detection rate of depressive symptoms among first year junior high school students in Yunnan Province was 29.5%. The detection rates of depressive symptoms in Han and minority first year junior high school students were 26.9% and 31.6%. After controlling for demographic variables such as gender, age, family residence and other confounding factors, the generalized linear model analysis results showed that the intake of leafy vegetables ( β= -0.07 , 95%CI =-0.12 to -0.01), flat fruits ( β=-0.06, 95%CI =-0.12 to -0.00) and hot natured fruits ( β=0.11, 95%CI = 0.04- 0.17) were associated with depressive symptoms in Han first year junior high school students (all P <0.05). The intake of melon and fruit vegetables ( β=-0.06, 95%CI =-0.11 to -0.01) and hot natured fruits ( β=0.06, 95%CI =0.01-0.12) were associated with depressive symptoms in ethnic minority first year junior high school students (both P <0.05).
Conclusions
The intake of vegetables and fruits among multi ethnic first year junior high school students in Yunnan Province is related to the risk of depressive symptoms. It is suggested to strengthen the consumption guidance and education of vegetables and fruits to prevent depressive symptoms among first year junior high school students.

ObjectiveTo construct a scale for the diagnosis of chronic atrophic gastritis (CAG) with turbid toxin accumulating in the stomach. MethodsFirst, a research group was established to construct the scale framework. Relevant literature of CAG with syndrome of turbid toxin accumulating in the stomach was searched in CNKI, Wanfang Database (WF), and VIP Database (CQVIP) from April 1, 2003 to April 1, 2023, and items were preliminarily selected after standardization of terms. Through clinical investigation, the discrete trend method, correlation coefficient method, Cronbach's coefficient method, and factor analysis method were used to screen symptom items, and the frequency method was used to screen signs, tongue coating, and pulse conditions. Three rounds of Delphi expert consultation were conducted to determine the items of the scale. The weight of each item was obtained by the analytic hierarchy process. ResultsA total of 49 articles were included, and 45 items were obtained after primary screening, including 28 symptoms, 2 signs, 10 tongue coatings, and 5 pulse conditions. After clinical investigation, 15 symptoms were retained, and 8 signs and pulse conditions of tongue coating were retained. The positive coefficients of experts in three rounds of Delphi expert consultation were 100%, 96.67%, and 100%, respectively. The expert authority coefficients were 0.86, 0.87, and 0.87, respectively, and the coordination coefficients were 0.18, 0.25, and 0.30. After core group discussion, Delphi method investigation, and AHP weight assignment, the diagnostic scale items of CAG with turbid toxin accumulating in stomach syndrome were finally established, namely, dark red or purplish tongue proper with yellow greasy (or dry) coating (30 points), epigastric stuffiness and fullness or pain (15 points), sticky and unsmooth defecation (10 points), taste disturbance (sticky mouth, fetid breath, bitter taste, 7 points), heartburn or acid regurgitation (6 points), dizziness and clouding (5 points), general heaviness and fatigue (5 points), slippery, string‑slippery, or slippery‑rapid pulse (5 points), dysuria (or yellow or deep yellow urine, 4 points), poor appetite (4 points), dull complexion (3 points), sticky, greasy, and fetid secretions (3 points), and poor sleep (3 points). ConclusionBased on the establishment, screening, confirmation, and weighting of an item pool, combined with subjective and objective approaches as well as qualitative and quantitative methods, a diagnostic scale for CAG with the syndrome of turbid toxin accumulating in the stomach was successfully constructed.

ObjectiveThis paper aims to evaluate the intervention effect of Gandou Fumu Decoction (GDFMD) in treating hepatolenticular degeneration with liver fibrosis of liver-kidney deficiency and phlegm-blood stasis syndrome, thereby providing evidence-based medical evidence for the treatment of Wilson's disease (WD)-related liver fibrosis with traditional Chinese medicine through clinical efficacy analysis. MethodsA total of 70 patients with WD-related liver fibrosis of liver-kidney deficiency and phlegm-blood stasis syndrome meeting the inclusion criteria were enrolled from Anhui Provincial Hospital of TCM from October 1, 2023, to October 1, 2024. Participants were divided into a control group and an observation group, with 35 cases in each group. The control group received conventional copper chelation therapy with sodium dimercaptopropanesulfonate (DMPS). On this basis, the observation group was additionally administered GDFMD orally. Each treatment course lasted eight days, for a total of four treatment courses. Efficacy evaluations were performed before treatment and after the second and fourth treatment courses, respectively. The clinical efficacy and safety of GDFMD in the treatment of WD-related liver fibrosis were assessed by comparing the changes in liver stiffness measurement (LSM), liver serological markers [alanine aminotransferase (ALT), aspartate aminotransferase (AST), type Ⅳ collagen (C-Ⅳ), laminin (LN), N-terminal propeptide of type Ⅲ procollagen (PⅢNP), and hyaluronic acid (HA)], fibrosis index based on 4 factors (FIB-4), AST to platelet ratio index (APRI), unified Wilson's disease rating scale part Ⅱ (UWDRS-Ⅱ), traditional Chinese medicine (TCM) syndrome score, 24-hour urinary copper, and safety indicators between the two groups before and after treatment. ResultsCompared with those before treatment, LSM levels decreased in both groups after two and four treatment courses (P<0.05). Compared with those after treatment, there was no statistically significant difference in the improvement of LSM levels in the observation group after two treatment courses, and the improvement of LSM levels in the observation group was more obvious after four treatment courses (P<0.05). Compared with those before treatment, the levels of HA, LN, PⅢNP, and C-Ⅳ decreased in both groups after two and four treatment courses (P<0.05). Compared with those after treatment, there was no statistically significant difference in the improvement of the C-Ⅳ levels in the observation group after two treatment courses, and the levels of HA, LN, and PⅢNP were more obvious (P<0.05). After four treatment courses in the observation group, the levels of HA, LN, PⅢNP, and C-Ⅳ were improved more significantly (P<0.05). Compared with those before treatment, ALT and AST levels decreased in both groups after two and four treatment courses (P<0.05). Compared with the control group after treatment, there was no statistically significant difference in the improvement of ALT and AST levels in the observation group after two treatment courses, and the improvement of ALT and AST levels in the observation group was more obvious after four treatment courses (P<0.05). Compared with those before treatment, APRI score and FIB-4 index level decreased in both groups after two and four treatment courses (P<0.05). Compared with those in control group after treatment, there was no statistically significant difference in the improvement of APRI score and FIB-4 index level in the observation group after two treatment courses, and the APRI score in the observation group was more obvious after four treatment courses (P<0.05), with no statistically significant improvement in the FIB-4 index difference. Compared with those before treatment, the levels of TCM syndrome scores decreased in both groups after two and four treatment courses (P<0.05). Compared with that of the control group after treatment, there was no statistically significant difference in the improvement of the level of TCM syndrome scores in the observation group after two treatment courses, and the improvement of the level of TCM syndrome scores in the observation group was more obvious after four treatment courses (P<0.05). Compared with those before treatment, the UWDRS-Ⅱ scores in both groups after two treatment courses were not improved obviously, and the UWDRS-Ⅱ scores in both groups decreased after four treatment courses (P<0.05). Compared with those of the control group after treatment, there was no statistically significant difference in the improvement of the UWDRS-Ⅱ scores in the observation group after two treatment courses, and the improvement of the UWDRS-Ⅱ scores in the observation group after four treatment courses was more obvious (P<0.05). Compared with those before treatment, the 24-h urine copper levels were significantly higher in both groups after two and four treatment courses (P<0.05). Compared with those in the control group after treatment, the 24-h urine copper levels in the observation group were significantly higher after two and four treatment courses (P<0.01). After two treatment courses, the 24-h urine copper level in the observation group showed a gradual decreasing trend, although it was higher than that before treatment. After four treatment courses, the control group had an improvement rate of 91.43%, an effective rate of 34.29%, and an apparent rate of 2.86%. The observation group had an improvement rate of 94.29%, an effective rate of 71.43%, and an apparent rate of 8.57%. The efficacy of the observation group was better than that of the control group (P<0.05). Conclusion① The efficacy of GDFMD combined with DMPS therapy in patients with WD-related liver fibrosis of liver-kidney deficiency and phlegm-blood stasis syndrome is significantly better than that of single DMPS therapy, and the advantages of the combined therapy are more obvious with the prolongation of the treatment cycle. ② GDFMD combined with the DMPS therapy program in the long-term application exhibits no obvious adverse reactions with good safety, which is worthy of clinical popularization and application.

ObjectiveThis paper aims to explore the risk factors for chronic atrophic gastritis (CAG) with turbidity toxin accumulation syndrome and establish a prediction model. MethodsClinical data of 180 patients with CAG who participated in the "clinical study of Xianglian Huazhuo Particles blocking CAG cancer transformation" of Hebei Sheng Zhong Yi Yuan from July 2021 to March 2022 were collected. After confounding factors were controlled by propensity score matching, patients were divided into a training set (namely dev) and a validation set (namely vad) in a seven to three ratio. The risk factors for CAG with turbidity toxin accumulation syndrome in the training set were investigated by using univariate Logistic regression analysis and least absolute shrinkage and selection operator (namely Lasso) regression algorithms. Subsequently, a model, named model 1se, was developed by using the training set data to predict the risk factors for CAG with turbidity toxin accumulation syndrome. The accuracy of the prediction model was assessed by using various methods, including the receiver operating characteristic (ROC) curve, Hosmer-Lemeshow test (H-L), calibration plot, and decision curve analysis (DCA). ResultsAge, body mass index (BMI), family history of cancer, job and life satisfaction, yellow and greasy fur with slippery pulse, and heavy body sensation were independent risk factors of the model. The prediction model showed excellent predictive value for both the training and validation sets. ConclusionThe established prediction model for CAG with turbidity toxin accumulation syndrome has high discrimination and excellent calibration, which could provide an excellent clinical basis for disease diagnosis and individualized treatment of patients.

Objective To investigate the distribution characteristics of Oncomelania hupensis snails in Yunnan Province fol-lowing interruption of schistosomiasis transmission, so as to provide the evidence for assessing the risk of schistosomiasis transmission and scientifically formulating the schistosomiasis surveillance program. Methods According to the requirements of the National Schistosomiasis Surveillance Scheme (2020 Edition), O. hupensis snail surveillance data were collected from 18 schistosomiasis-endemic counties (cities, districts) in Yunnan Province from 2020 to 2024, including area of snail survey, area of snail habitats, area of re-emerging snail habitats, number of frames surveyed, number of frames with O. hupensis snails, number of O. hupensis snails captured, and number of living snails, and the occurrence of frames with snails and mean density of living snails were calculated. Changes in snail status over the 5-year period from 2020 to 2024 and the differences in snail distributions specified by epidemic intensity, environmental type, and vegetation type were analyzed. Results The areas of snail survey increased from 1 727.96 hm2 in 2020 to 3 894.45 hm2 in 2024 (peak) across 18 schistosomiasis-endemic counties (cities, districts) in Yunnan Province during the period from 2020 through 2024. The areas of snail habitats increased from 70.36 hm2 in 2020 to a peak in 2023 (172.04 hm2), followed by a reduction to 132.36 hm2 in 2024, and the areas of re-emerging snail habitats increased from 42.71 hm2 in 2020 to a peak in 2022 (78.43 hm2), followed by a reduction to 40.21 hm2 in 2024. The occurrence of frames with snails and mean density of living snails increased from 1.24% (3 025/244 404) and (0.033 2 ± 0.038 7) snails/0.1 m2 in 2020 to peaks at 2.03% (6 231/307 563) and (0.066 9 ± 0.068 4) snails/0.1 m2 in 2023, followed by reductions to 1.04% (5 829/559 941) and (0.032 6 ± 0.057 7) snails/0.1 m2 in 2024, respectively. There was a significant difference in the occurrence of frames with snails over the 5-year study period (χ2 = 1 962.95, P < 0.05), and the occurrence of frames with snails reduced by 48.71% in 2024 relative to in 2023 (χ2 = 1 411.05, P < 0.005); however, there was no significant difference in the mean density of living snails over the 5 years (H = 5.310, P > 0.05). There were significant differences in the occurrence of frames with snails (χ2 = 481.27, P < 0.05) and mean density of living snails (H = 6.872, P < 0.05) in schistosomiasis-endemic areas with different epidemic intensities. The occurrence of frames with snails (χ2 = 25.32 and 38.70, both P values < 0.017) and mean density of living snails (Z = 28.55 and 49.96, both P values < 0.017) were higher in schistosomiasis transmission-interrupted and eliminated areas with snails than in schistosomiasis-eliminated areas without snails, and the occurrence of frames with snails (χ2 = 453.54, P < 0.017) and mean density of living snails (Z = −56.97, P < 0.017) were higher in schistosomiasis-eliminated areas with snails than in schistosomiasis transmission-interrupted areas with snails. O. hupensis snails were mainly distributed in paddy fields, dry farmlands and ditches; however, the occurrence of frames with snails (13.40%, 424/3 164) and mean density of living snails [(0.252 8 ± 0.158 7) snails/0.1 m2] were higher in ponds/weirs than in other types of environments (both P values < 0.05). Rice, dry farmland crops and weeds were main vegetations in which O. hupensis snails were distributed, and the occurrence of frames with snails (2.29%, 7 111/310 140) and mean density of living snails [(0.072 3 ± 0.018 9) snails/0.1 m2] were higher in weeds than in other types of environments (both P values < 0.05). Conclusions O. hupensis snails have been effectively controlled in Yunnan Province following implementation of integrated schistosomiasis control measures; however, there are still risk factors for schistosomiasis transmission, including reduced attention to schistosomiasis control and snail re-emergence. Improved control efforts and surveillance system construction and timely identification of risk factors of snail status and timely management are recommended to ensure the achievement of the target of schistosomiasis elimination as scheduled.

Objective:
To define the mechanism by which swine TRIM25 restricts vesicular stomatitis virus replication.
Methods:
Porcine 3D4/21 cells with TRIM25 overexpression or knockdown were infected with vesicular stomatitis virus. Viral replication was quantified by immunoblotting, quantitative reverse transcription polymerase chain reaction, and 50% tissue culture infectious dose assays. Type I interferon signaling was assessed by transcript quantification, interferon-beta and interferon-stimulated response element reporter assays, and co-immunoprecipitation.Viral RNA binding was tested by RNA immunoprecipitation.
Results:
TRIM25 overexpression reduced viral RNA and infectious titers, whereas TRIM25 knockdown increased replication (p < 0.01). TRIM25 increased interferon-beta and interferon-stimulated gene expression and enhanced interferon-beta and interferonstimulated response element promoter activity (p < 0.01). Mechanistically, TRIM25 promoted Lys63-linked ubiquitination of RIG-I and increased phosphorylation of TANK-binding kinase 1 and interferon regulatory factor 3. TRIM25 also bound vesicular stomatitis virus genomic RNA, and binding required the C-terminal region.
Conclusions
and Relevance: Porcine TRIM25 restricts vesicular stomatitis virus replication by amplifying type I interferon signaling and directly binding viral RNA.
