With the deepening of population aging and the rising prevalence of chronic diseases among the elderly in China， the traditional elderly care models are facing challenges. This paper proposed a community-integrated medical-nursing-rehabilitation-care service model， characterized by “integration， flexibility， community orientation， and demand orientation.” This model optimizes and combines various service resources such as healthcare， elderly care， rehabilitation， and nursing at the community level， providing more comprehensive and targeted services for the elderly with chronic diseases in the community. However， a series of challenges existed in dimensions such as the service integration， benefit distribution， resources and funds， as well as policies and systems， hindering the sustainable development of the community-integrated medical-nursing-rehabilitation-care service model. Future efforts should focus on constructing a more standardized collaborative system， clarifying standards for resource investment and benefit distribution， as well as strengthening policy guidance， financial support， and talent team development.

Objective: To explore the longitudinal associations between non-restorative sleep (NRS) and non-suicidal self-injury (NSSI) among college freshmen, so as to provide a reference framework for intervention targeting adolescent NSSI behaviors. Methods: Utilizing a combination of convenience sampling and cluster randomized sampling, a 1 year longitudinal assessment across three time points (T1, T2, and T3) was conducted from October 2023 to October 2024 among 967 college freshmen recruited from a provincial university in Guangdong. The survey was administered using the Non restorative Sleep Scale (NRSS) and the Adolescent Non suicidal Self injury Assessment Questionnaire (ANSAQ). Data analysis was performed using unconditional latent growth curve modeling (LGCM), cross lagged panel modeling (CLPM), and parallel latent growth modeling. Results: The detection rates of NSSI behaviors in college students at T1, T2, and T3 were 18.20%, 11.89%, and 7.55%, respectively. From T1 to T3, NRSS scores showed a linear increasing trend ( β =0.67), while ANSAQ scores showed a linear downward trend ( β =-0.17) (both P < 0.05 ). Cross lagged analysis showed that NRSS scores negatively predicted ANSAQ scores (T1 NRSS scores → T2 ANSAQ scores: β =-0.10; T2 NRSS scores → T3 ANSAQ scores: β =-0.09; both P <0.01). However, in the reverse pathways, the predictive effects of ANSAQ scores on subsequent NRSS scores were not statistically significant ( β =-0.02, -0.02, both P >0.05). Parallel latent growth modeling indicated that both the initial level ( β =-0.49) and the rate of change ( β =-0.29) of NRSS scores predicted the developmental trajectory of ANSAQ scores (both P <0.05). Conclusions NRS is a risk factor for NSSI behaviors among college freshmen. Early assessment of and targeted interventions for NRS could potentially help mitigate the risk of NSSI occurrence.

Objective: To explore the longitudinal relationships between sleep problems and non suicidal self injury (NSSI) behaviors in college students, so as to provide a theoretical basis for the prevention and intervention of NSSI. Methods: In October 2023 (T1), a total of 1 009 college students from two provincial colleges in Guangdong were selected by using a combination of convenience sampling and stratified cluster random sampling for a 1 year follow up survey (October 2024, T2). The students were assessed by using the Insomnia Severity Index(ISI), Non restorative Sleep Scale(NRSS), Epworth Sleepiness Scale (ESS), and Adolescent Non suicidal Self injury Assessment Questionnaire(ANSAQ). Data analysis was performed using McNemar’s test and Logistic regression. Results: The detection rate of NSSI behaviors was 18.83% at T1 and decreased to 7.73% at T2, with a statistically significant difference ( χ 2=66.24, P <0.01). The trajectories of NSSI behaviors were divided into persistent group (4.06%), new onset group (3.67%), remission group (14.77%), and resistance group (77.50%). Logistic regression analysis showed that sleep less than 7 hours per day at night, insomnia (mild, moderate to severe), non restorative sleep (moderate, severe), daytime sleepiness, and weekly nightmare frequency (1-2, ≥3 times) were associated with NSSI behaviors at T1 ( OR =5.02, 2.39, 5.51, 3.47, 9.70, 2.36, 2.63, 4.74, all P <0.01). Insomnia (mild, moderate to severe), severe non restorative sleep, daytime sleepiness, and weekly nightmares ≥3 times at T1 all increased the risk of NSSI behaviors at T2 ( OR =1.76, 4.15, 4.05, 1.88, 5.63, all P < 0.05 ). Moderate to severe insomnia, severe non restorative sleep, daytime sleepiness, and weekly nightmares ≥3 times at T1 increased the risk of belong to the new onset NSSI group ( OR =5.05, 3.37, 2.08, 5.86, all P <0.05). Conclusions Insomnia, non restorative sleep, daytime sleepiness, and frequent nightmares are important risk factors for NSSI behaviors among college students. Early assessment and intervention of sleep problems may be an important strategy for the prevention and treatment of NSSI.

Background Polycyclic aromatic hydrocarbons (PAHs) are widely known atmospheric pollutants, which can cause serious harm to human body and ecological environment. Objective To analyze the concentrations and sources of PAHs in atmospheric PM_2.5 in Zhifu District and Longkou City during the heating period in Yantai. Methods Two monitoring sites in Zhifu District and Longkou City of Yantai were selected, and PM_2.5 sample collection was carried out from April 2023 to March 2024. Gas chromatography-mass spectrometry was applied to analyze the concentrations of PAHs in atmospheric PM_2.5 during the heating period (from November 2023 to March 2024) and the non-heating period (from April to October 2023). The concentrations of PAHs in the two periods were compared and the sources of PAHs during the heating period were analyzed by characteristic ratio method. Results During the heating period, the total concentration ranges of PAHs in atmospheric PM_2.5 at the monitoring sites in Zhifu District and Longkou City of Yantai were (1.59-23.70) ng·m⁻³ and (2.08-149.72) ng·m⁻³ respectively, and the medians (M) and the 25th and 75th percentiles (P₂₅, P₇₅) were 4.99 (2.61, 8.09) ng·m⁻³ and 15.46 (8.15, 29.05) ng·m⁻³ respectively. The PAHs concentrations in Longkou City were significantly higher than those in Zhifu District in all months (P<0.05). The highest median total concentrations of PAHs in both sites were reported in January (8.14 ng·m⁻³ and 81.56 ng·m⁻³ respectively). In the non-heating period, the M (P₂₅, P₇₅) of the total PAHs concentrations at the two sites were 1.59 (1.59, 2.78) ng·m⁻³ and 4.11 (2.94, 7.97) ng·m⁻³ respectively, much lower than those in the heating period (P<0.01). The order of composition of PAHs by ring number in PM_2.5 at both sites was 4-ring> 5-ring> 6-ring, with the 4-ring contributing the largest proportion (65.33% and 46.39% respectively). Fluoranthene had the highest concentration among PAHs at both sites, with concentrations M (P₂₅, P₇₅) of 1.29 (0.51, 1.78) ng·m⁻³ and 2.32 (1.30, 3.82) ng·m⁻³ respectively. The characteristic ratios of fluoranthene/(fluoranthene + pyrene), fluoranthene/pyrene, benzo[a]anthracene/(benzo[a]anthracene + chrysene), pyrene/benzo[a]pyrene, benzo[a]pyrene/(benzo[a]pyrene + chrysene), benzo[a]pyrene/benzo[g,h,i]pyrene, and indeno[1,2,3-c,d]pyrene/(indeno[1,2,3-c,d]pyrene + benzo[g,h,i]pyrene) in Zhifu District were 0.62, 1.65, 0.41, 4.48, 0.50, 0.93 and 0.47 respectively, and those in Longkou were 0.57, 1.35, 0.40, 2.89, 0.29, 0.79 and 0.47 respectively. The results showed that PAHs pollutants were generated by combination of coal combustion, vehicle exhaust emissions and gasoline combustion. Conclusion During the heating period in Yantai area, the total concentration of PAHs in atmospheric PM_2.5 is significantly higher than that in the non-heating period. Among them, during the heating period, the pollution level in Longkou City is significantly higher than that in Zhifu District. The local PAHs may be sourced from mixed pollution, and the main sources include gasoline, and coal combustion and vehicle exhaust emissions.

ObjectiveTo investigate the effects of Dihuang Yinzi on the cognitive function in the mouse model of learning and memory impairments induced by scopolamine （SCOP） and explore the treatment mechanism. MethodsA mouse model of learning and memory impairment was induced by intraperitoneal injection of SCOP. Sixty male C57BL/6J mice were randomized into six groups： control （0.9% NaCl， n=10）， model （SCOP 1 mg·kg^-1·d^-1， n=10）， low-， medium-， and high-dose Dihuang Yinzi （SCOP 1 mg·kg^-1·d^-1 + Dihuang Yinzi 5.5， 11.0， and 22.0 g·kg^-1·d^-1， n=10）， and donepezil （SCOP 1 mg·kg^-1·d^-1 + donepezil 0.84 mg·kg^-1·d^-1， n=10）. Mice were administrated with corresponding drugs for 6 weeks. Modeling started in the 4th week， and mice in other groups except the control group were injected with SCOP intraperitoneally 40 min after daily gavage. Behavioral testing began in the 5th week， 30 min after modeling each day. The Morris water maze and novel object recognition tests were carried out to evaluate the spatial learning and memory function of mice. Nissl staining was employed to observe the survival of neurons and Nissl bodies in the hippocampal CA1 region. Western blot was employed to determine the protein levels of silent information regulator 2 （SIRT2）， α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid （AMPA） receptor 1 （GluA1）， protein kinase A （PKA）， cAMP response element-binding protein （CREB）， phosphorylated-CREB （p-CREB）， postsynaptic density protein 95 （PSD95）， growth-associated protein-43 （GAP-43）， and synaptophysin （SYN） in the hippocampus. Immunofluorescence was used to detect the expression of doublecortin （DCX） in the hippocampal dentate gyrus （DG） region. ResultsCompared with the control group， the model group showed impaired learning and memory （P<0.01）， obvious neuronal damage in the hippocampal CA1 region， a reduction in neuron survival （P<0.01）， a decrease in DCX expression in the hippocampal DG region （P<0.01）， down-regulated proteins levels of GluA1， PKA， p-CREB/CREB， PSD95， SYN， and GAP-43 in the hippocampal tissue （P<0.05， P<0.01）， and an up-regulated protein level of SIRT2 （P<0.01）. Compared with the model group， the medium- and high-dose Dihuang Yinzi groups and the donepezil group showed improvements in learning and memory （P<0.05， P<0.01）， while the low-， medium-， and high-dose Dihuang Yinzi groups and the donepezil group had increased neuron survival （P<0.05， P<0.01）. The medium-dose Dihuang Yinzi group and the donepezil group showed increased DCX expression （P<0.05， P<0.01）. The medium- and high-dose Dihuang Yinzi groups and the donepezil group showed up-regulation in the protein levels of GluA1， PKA， p-CREB/CREB， PSD95， SYN， and GAP-43 （P<0.05， P<0.01） and down-regulation in the protein level of SIRT2 （P<0.01）. ConclusionDihuang Yinzi can improve the cognitive function in the mouse model of learning and memory impairments induced by SCOP by inhibiting the upregulation of SIRT2， activating the PKA/CREB signaling pathway， improving synaptic plasticity， and reducing hippocampal neuronal damage.

Dynamic changes in the physiochemical, structural, and flavor characteristics of ginger-juice milk curd were explored by texture analysis, scanning electron microscopy, rheometry, electronic tongue, and gas chromatography-mass spectrometry (GC-MS). Protein electrophoresis showed that ginger juice could hydrolyze α_s-, β-, and κ-casein. Curd formation was initiated at 90 s, marked by significant changes in intensity detected via intrinsic fluorescence. The contents of soluble protein and calcium decreased rapidly during coagulation, while the caseinolytic activity, storage moduli, loss moduli, hardness, adhesiveness, and water-holding capacity increased, resulting in a denser gel structure with smaller pores and fewer cavitations as observed by scanning electron microscopy. Electronic tongue analysis indicated that milk could neutralize the astringency and saltiness of ginger juice, rendering the taste of ginger-juice milk curd more akin to that of milk. Approximately 70 volatile components were detected in ginger-juice milk curd. α‍-Zingiberene, α‍-curcumene, β‍-sesquiphellandrene, and β‍-bisabolene were the predominant volatile flavor compounds, exhibiting an initial decrease in content followed by stability after 90 s. Decanoic acid, γ-elemene, and caryophyllene were identified as unique volatile compounds after mixing of milk and ginger juice. Understanding the dynamic changes in these characteristics during coagulation holds significant importance for the production of ginger-juice milk curd.

OBJECTIVE To investigate the impact of Tongxinluo capsules on the pharmacokinetics of rivaroxaban in rats. METHODS Rats were randomly divided into rivaroxaban alone group （2.70 mg/kg）， low-dose Tongxinluo capsules combined with rivaroxaban group （Tongxinluo capsules 0.28 g/kg+rivaroxaban 2.70 mg/kg）， and high-dose Tongxinluo capsules combined with rivaroxaban group （Tongxinluo capsules 0.84 g/kg+rivaroxaban 2.70 mg/kg）， with five rats in each group. Following seven consecutive days of gavage with normal saline or the corresponding doses of Tongxinluo capsules， the rats were subjected to a final gavage administration of rivaroxaban. Blood samples were collected at 0 h prior to the final administration and at 0.16， 0.33， 0.50， 0.75， 1， 1.5， 2， 4， 8， 12 and 24 h post-final administration. The plasma concentration of rivaroxaban in rats was determined by high-performance liquid chromatography-tandem mass spectrometry. The pharmacokinetic parameters [peak concentration （cmax）， half-life （t1/2）， area under the drug concentration time curve （AUC）， mean residence time （MRT）， clearance （CL）， apparent volume of distribution （Vd） and peak time （tmax）] of each group were calculated using a non-compartmental model of MonolixSuite 2023R1 pharmacokinetic software. RESULTS Compared with rivaroxaban alone group， AUC₀₋ₜ and AUC0-∞ of rivaroxaban in rats were increased significantly in high-dose Tongxinluo capsules+rivaroxaban group （P＜0.05）， while CL was decreased significantly （P＜0.05）； t1/2 and MRT were shortened， tmax was extended， cmax was increased， while Vd was decreased， but there was no statistical significance （P＞0.05）. CONCLUSIONS Rivaroxaban combined with Tongxinluo capsules significantly increases the plasma exposure of rivaroxaban in rats. Potential drug-drug interactions should be considered in clinical practice based on the co-administration conditions.
