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.

Urinary incontinence is a common complication following robot-assisted radical prostatectomy (RARP). Urethral length has been identified as a factor affecting postoperative continence recovery. In this meta-analysis, we examined the association between use of the maximal urethral length preservation (MULP) technique and postoperative urinary continence in patients undergoing RARP. We conducted a comprehensive search of PubMed, Web of Science, Embase, and the Cochrane Library up to December 31, 2023. The quality of the literature was assessed using the Newcastle-Ottawa Scale. A random-effects meta-analysis was performed to synthesize data and calculate the odds ratio (OR) from eligible studies on continence and MULP. Six studies involving 1869 patients met the eligibility criteria. MULP was positively associated with both early continence (1 month after RARP; Z = 3.62, P = 0.003, OR = 3.10, 95% confidence interval [CI]: 1.68-5.73) and late continence (12 months after RARP; Z = 2.34, P = 0.019, OR = 2.10, 95% CI: 1.13-3.90). Oncological outcomes indicated that MULP did not increase the overall positive surgical margin rate or the positive surgical margin status at the prostate apex (both P > 0.05). In conclusion, the use of the MULP technique in RARP significantly improved both early and late postoperative continence outcomes without compromising oncological outcomes.

Accurate prediction of drug-target interactions (DTIs) plays a pivotal role in drug discovery, facilitating optimization of lead compounds, drug repurposing and elucidation of drug side effects. However, traditional DTI prediction methods are often limited by incomplete biological data and insufficient representation of protein features. In this study, we proposed KG-CNNDTI, a novel knowledge graph-enhanced framework for DTI prediction, which integrates heterogeneous biological information to improve model generalizability and predictive performance. The proposed model utilized protein embeddings derived from a biomedical knowledge graph via the Node2Vec algorithm, which were further enriched with contextualized sequence representations obtained from ProteinBERT. For compound representation, multiple molecular fingerprint schemes alongside the Uni-Mol pre-trained model were evaluated. The fused representations served as inputs to both classical machine learning models and a convolutional neural network-based predictor. Experimental evaluations across benchmark datasets demonstrated that KG-CNNDTI achieved superior performance compared to state-of-the-art methods, particularly in terms of Precision, Recall, F1-Score and area under the precision-recall curve (AUPR). Ablation analysis highlighted the substantial contribution of knowledge graph-derived features. Moreover, KG-CNNDTI was employed for virtual screening of natural products against Alzheimer's disease, resulting in 40 candidate compounds. 5 were supported by literature evidence, among which 3 were further validated in vitro assays.

Objective To explore the application effect of recombinant human granulocyte colony stimulating factor(rhG-CSF)in the treatment of chemotherapy-induced oral mucositis in children.Methods Totally 60 children with chemotherapy-induced oral mucositis who underwent chemotherapy in the tumor surgery of our hospital from January 2020 to June 2022 were randomly divided into two groups,30 cases each.The control group was given physiological saline oral care,and the experimental group was given rhG-CSF oral care.Compare the intervention effect,oral mucositis grading,quality of life[short form of health survey(SF-36)]and nursing satisfaction of parents of the two groups.Results The total effective rate of the experimental group was higher than that of the control group(P<0.05).After 5 days of intervention,the score of oral mucositis in the experimental group was better than that in the control group(P<0.05).After 5 days of intervention,the SF-36 score of children in the two groups was higher than that before intervention,and that in the experimental group was higher than that in the control group(P<0.05).The parents'satisfaction in the experimental group was higher than that in the control group(P<0.05).Conclusion rhG-CSF oral care can effectively improve the intervention effect of chemotherapy-induced oral mucositis in children,reduce the grade of oral mucositis,improve the quality of life of children,and improve the nursing satisfaction of parents of children.

ObjectiveTo observe the clinical efficacy of Tongfu Xiezhuo enema in treating stage 3-4 chronic kidney disease （CKD） and the effect of the therapy on the neutrophil-to-lymphocyte ratio （NLR） as an inflammation marker. MethodSixty patients diagnosed with stage 3-4 CKD who visited the Nephrology Department of the First Affiliated Hospital of Heilongjiang University of Chinese Medicine from December 2022 to June 2023 were included and randomly assigned into observation and control groups in a ratio of 1∶1. The control group received conventional therapy plus Shenkang suppositories， while the observation group received conventional therapy plus Tongfu Xiezhuo enema. After 8 weeks of treatment， the clinical efficacy was assessed based on the changes in traditional Chinese medicine （TCM） symptom scores， renal function indicators， and NLR. Result① Both groups showed decreases in TCM symptom scores after treatment （P<0.01）， and the decreases were more significant in the observation group than in the control group （P<0.05）. The total response rate of TCM symptoms in the observation group was 79.31% （23/29）， which was higher than that （62.96%， 17/27） in the control group （Z=0.604，P<0.05）. ② After treatment， the observation group showed declined serum levels of creatinine （SCr）， blood urea nitrogen （BUN）， and cystatin C （Cys C） and increased glomerular filtration rate （GFR） （P<0.01）， and the control group showed lowered SCr level and increased GFR （P<0.05）. The observation group had lower SCr level and higher GFR than the control group after treatment （P<0.05）. The total response rate of renal function in the observation group was 79.31% （23/29）， which was higher than that （55.56%， 15/27） in the control group （Z=1.127，P<0.01）. ③ The NLR in the observation group decreased after treatment （P<0.05）， and it was lower than that in the control group （P<0.05）. ④ There were no significant differences in safety indicators between the two groups before and after treatment. ConclusionTongfu Xiezhuo enema ameliorated symptoms and improved renal function indicators in the patients with stage 3-4 CKD by reducing the NLR and inhibiting inflammation.

The toad, known for its various medicinal properties including parotid gland secretion (toad venom), dried skin, and gallbladder (toad bile), holds considerable medicinal applications as a valuable traditional Chinese animal medicine. Currently, in-depth attentions have been paid to the chemical composition and pharmacological properties of toad venom and skin; however, a lesser number of detailed analyses were concentrated on the toad bile. This review provides an overview of the chemical constituents in the bile of the Bufo genus, with a special focus on the cholestane and bufadienolides, and highlights the progress in their biosynthetic pathway and pharmacological activities. The analysis uncovers a distinct category of unsaturated Δ²² or Δ²³-C₂₇/C₂₈ bile acids in the toad gallbladder, potentially acting as key intermediaries in forming C-17 α-pyrone of bufadienolides. Furthermore, the high presence of 3α-OH configured bufadienolides in toad bile, in contrast to the common 3β-OH configured found in toad venom or skin, indicates a possible link between their minimal toxicity and the toad's self-defensive or physiological control. This review provides scientific basis for the development and utilization of toad bile resources, and provides useful reference for the discovery of lead compounds, analysis of the biosynthetic pathway of bufadienolides, and research on toad physiology.

ObjectiveTo observe the clinical efficacy and safety of Chaihu Shugansan combined with Xuanfu Daizhetang （CHSG-XFDZ） in the management of Barrett's esophagus （BE） with liver-stomach disharmony. MethodA randomized， parallel， controlled， double-blind clinical trial was conducted. BE patients who met the inclusion criteria were randomized into an observation group and a control group， with 34 patients in each group. The observation group was treated with CHSG-XFDZ combined with omeprazole capsules， and the control group was treated with CHSG-XFDZ mimetic combined with omeprazole capsules. Both groups were treated for 12 weeks. The traditional Chinese medicine （TCM） symptom scores， response rate， BE lesion area， BE pathological changes， and bile acid profile were taken as the indicators to jointly evaluate the clinical efficacy and safety of the two groups. ResultA total of 62 patients who completed the trial were included for statistical analysis， including 32 in the observation group and 30 in the control group. There were no statistically significant differences in baseline demographics or disease characteristics between two groups， which suggested that the two groups were comparable. The total response rate in the observation group was 93.7% （30/32）， which was higher than that （60.0%， 18/30） in the control group （χ²=24.766， P<0.05）. After treatment， the response rate regarding the pathological changes in the observation group was 62.5% （20/32）， which was higher than that （23.3%， 7/30） in the control group （χ²=10.270， P<0.05）. The response rate regarding the BE lesion area change in the observation group was 21.9% （7/32）， which had no statistically significant difference from that （6.7%， 2/30） in the control group， which indicated that the advantages of the two regimens were not obvious in terms of reducing the area of BE lesions. Compared with the control group after treatment， the observation group regulated the bile acid profile， which pointed out the direction for further exploring the mechanism of CHSG-XFDZ in treating BE. Neither group showcased adverse reactions with clinical significance during the treatment period. ConclusionCHSG-XFDZ outperformed the control group in terms of alleviating TCM symptoms， ameliorating pathological changes， and improving the bile acid profile in the BE patients with liver-stomach disharmony. It demonstrates certain potential in reducing the lesion area. This formula is safe and effective in treating BE patients with liver-stomach disharmony and deserves further clinical research and widespread application.
