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 compare the therapeutic effects of 0.05% cyclosporine and 0.1% fluorometholone eye drops in patients with moderate and severe dry eye.Methods:A randomized controlled study was conducted.Fifty-two patients (52 eyes) with moderate to severe dry eye in Tianjin Medical University Eye Hospital from August 2021 to December 2022 were enrolled and randomly divided into 0.05% cyclosporine group and 0.1% fluorometholone group by random number table method, with 26 cases (26 eyes) in each group.Patients received 0.05% cyclosporine eye drops (2 times/day) and 0.1% fluorometholone eye drops (2 times/day) combined with calf blood deproteinized extract eye drops (4 times/day) according to the grouping.Before and 1, 3 and 6 months after treatment, clinical symptoms and signs were observed and Ocular Surface Disease Index (OSDI) score, corneal fluorescein staining (CFS) score, Schirmer Ⅰ test (SⅠT), non-invasive first tear film break-up time (NIBUTf), and conjunctival goblet cell (CGC) density were recorded.Before treatment and after 6 months of treatment, changes in corneal nerves and dendritic cells (DC) were observed by in vivo confocal microscopy (IVCM).This study adhered to the Declaration of Helsinki and was approved by the Medical Ethics Committee of Eye Hospital of Tianjin Medical University (No.2021KY-17).Written informed consent was obtained from each subject. Results:Compared with the 0.1% fluorometholone group, CFS score decreased after 1 month of treatment, but SⅠT, NIBUTf and CFS score increased after 3 months of treatment, and OSDI score, SⅠT and CFS score decreased after 6 months of treatment in the 0.05% cyclosporine group, showing statistically significant differences (all at P<0.05).Compared with baseline, in the 0.05% cyclosporine group, NIBUTf increased and CFS score decreased after 1 month of treatment, OSDI score and CFS score decreased, SⅠT and NIBUTf increased after 3 and 6 months of treatment, showing statistically significant differences (all at P<0.05).In the 0.1% fluorometholone group, CFS score decreased after 3 months of treatment, OSDI score and CFS score decreased, SⅠT increased after 6 months of treatment compared to baseline, showing statistically significant differences (all at P<0.05).OSDI score and CFS score decreased, SⅠT increased after 6 months of treatment compared to 3 months of treatment in the 0.05% cyclosporine group, and the differences were statistically significant (all at P<0.05).Baseline and CGC densities after 1, 3 and 6 months of treatment were (147.66±17.29), (195.44±15.46), (210.36±19.15) and (282.09±22.63)cells/mm 2 in the 0.05% cyclosporine group and (138.09±17.29), (95.67±15.46), (117.77±19.15) and (109.13±22.63)cells/mm 2 in the 0.1% fluorometholone group, respectively, with a statistically significant overall difference ( Fgroup=11.724, P<0.001; Ftime=4.837, P=0.005).Compared with the 0.1% fluorometholone group, CGC density in the 0.05% cyclosporine group increased after 1, 3 and 6 months of treatment, with statistically significant differences (all at P<0.05).Compared with baseline, the CGC density increased in the 0.05% cyclosporine group after 1, 3 and 6 months of treatment, and the differences were statistically significant (all at P<0.05).Compared with the 0.1% fluorometholone group, the corneal nerve fiber density in the 0.05% cyclosporine group increased after 6 months of treatment, and corneal DC density, area and dendrite number decreased, showing statistically significant differences (all at P<0.05). Conclusions:Cyclosporine 0.05% eye drops combined with calf blood deproteinized extract eye drops can improve symptoms and signs in patients with moderate to severe dry eye, and the long-term effect is better than that of 0.1% fluorometholone plus calf blood deproteinized extract eye drops.

Objective:
To explore the relationship between processed food consumption and blood pressure level of students in a university in Yunnan Province, so as to provide the reference for preventing hypertension in university students.
Methods:
In October 2021, a cluster sampling method was used to select 4 781 freshmen from a university in Kunming, Yunnan Province. The frequency of processed food consumption of university students was assessed by using the dietary frequency questionnaire, and height, weight and blood pressure were measured. Mann-Whitney test and Kruskal-Wallis test were used to compare the differences in blood pressure level of university students with different demographic variables, and the association between processed food consumption and blood pressure level was analyzed with a generalized linear model.
Results:
Among the students of a university in Yunnan Province, the detection rates of systolic prehypertension and hypertension were 33.86% and 1.23%, and the detection rates of diastolic prehypertension were 32.13% and hypertension 7.22%. The results of generalized linear model analysis showed that after controlling for demographic variables and other variables that might affect the blood pressure level of university students, the consumption of processed food (bread and cake: β =0.15, 95% CI =0.01-0.29) and ultra processed food (coffee beverage: β =-0.29, 95% CI =-0.54--0.03) were associated with systolic blood pressure level( P <0.05). The consumption of processed food (salted duck egg: β =0.21, 95% CI =0.01-0.41) was correlated with the diastolic blood pressure of college students ( P <0.05).
Conclusions
Processed food consumption in university students may increase the risk of high blood pressure.The education of healthy eating among college students should be strengthened to reduce the consumption of processed foods.

The presence of replication-competent HBV DNA in the liver and/or serum of HBsAg-negative individuals is a sufficient and necessary condition for the diagnosis of occult hepatitis B virus infection (OBI). In recent years, Chinese scholars have proposed what is considered a more "rigorous" definition, i.e., on this basis, HBV window period (WP) infection is excluded, which corresponds to a serum HBV DNA level of below the lower limit of detection or a low positive value (< 200 IU/mL). As the definition of WP for HBV infection remains unclear and its duration is highly variable, "HBV DNA < 200 IU/mL" is not the only criterion in OBI patients. Therefore, it is believed that there is still a lack of sufficient basis and operability for the definition of OBI based on "the exclusion of HBV WP infection" and "HBV DNA < 200 IU/mL" as "rigorous" conditions for the diagnosis of OBI.

Alzheimer's disease (AD) is associated with the impairment of white matter (WM) tracts. The current study aimed to verify the utility of WM as the neuroimaging marker of AD with multisite diffusion tensor imaging datasets [321 patients with AD, 265 patients with mild cognitive impairment (MCI), 279 normal controls (NC)], a unified pipeline, and independent site cross-validation. Automated fiber quantification was used to extract diffusion profiles along tracts. Random-effects meta-analyses showed a reproducible degeneration pattern in which fractional anisotropy significantly decreased in the AD and MCI groups compared with NC. Machine learning models using tract-based features showed good generalizability among independent site cross-validation. The diffusion metrics of the altered regions and the AD probability predicted by the models were highly correlated with cognitive ability in the AD and MCI groups. We highlighted the reproducibility and generalizability of the degeneration pattern of WM tracts in AD.

BACKGROUND:
LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer.
METHODS:
We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels.
RESULTS:
On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]).
CONCLUSION:
LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile.

10.School Feeding Programs in the United States during 1853-2010
Chinese Journal of School Health 2023;44(2):173-175
Abstract
The Children s Aid Society of New York has been providing free food to students at local vocational schools since 1853. It wasn t until 1975 that the school lunch program was permanently mandated by Congress. The National School Lunch Program in America has gone through a historic process from its inception and establishment to its development. The continued interest and oversight of the American people, public opinion guidance by progressive people like nutrition reformers, home economics and other are external factors in the continued development of this program. The timely enactment of the bill by the federal government and the high concern of senior leaders on this project is an important prerequisite for continued development. Integrating this program into the national agricultural development strategy and realizing the overall development philosophy is the key to the sustainability of this program. Paying attention to children s physical health is the core reason why American School Feeding Programs focus on children s diet quantity to children s nutritional quality. All of these factors contribute to the development of this project.
