This study was aimed to observe the effect of Bai-Zhu Fu-Ling (BZFL) Decoction in different proportion-ing on VIP and VIPR1 in Crohn's disease (CD) rats with spleen deficiency syndrome, in order to further explore the immunologic mechanism of BZFL Decoction on CD. The CD rat model with spleen deficiency syndrome was estab-lished using exhaustion and hunger. The model rats were treated by BZFL Decoction with different proportioning, and immunohistochemistry (IHC) was used to detect the expression of VIP and its receptor in colon tissues. The results showed that comparing to the blank control group, the level of VIP and its receptor of the model group significantly increased (P< 0.05). Comparing to the model group, the level of VIP and its receptor in BZFL Decoction B5 group (Rhizoma A tractylodis Macrocephalae:Poria = 12:15), B6 group (Rhizoma A tractylodis Macrocephalae:Poria = 15:12) and B7 group (Rhizoma A tractylodis Macrocephalae:Poria = 18:9) was significantly decreased (P< 0.05). It was con-cluded that the effect of BZFL Decoction of B5 group, B6 group and B7 group was better than other groups in VIP and its receptor which can regulate the VIP and its receptor, inhibit the releasing of inflammatory factors and reduce intestinal inflammation injury.

Objective:
To investigate how parental divorce impacts psychological abuse and neglect among middle and high school students, so as to provide evidence for the development of family intervention strategies for mental health promotion.
Methods:
A stratified random cluster sampling method was employed to select students from 23 middle and high schools in Nanchong, Neijiang, and Luzhou. Online questionnaires utilizing the General Data Questionnaire and the Child Psychological Abuse and Neglect Scale (CPANS) were administered. Propensity score matching (PSM) was used to compare individual characteristics between parent divorce and the control groups. The χ 2 test was then employed to analyze differences in psychological abuse and neglect across variables, with Logistic regression used to treat psychological abuse and neglect as dependent variables.
Results:
After PSM, there were 1 898 cases in both parent divorce and control groups. There was no significant difference in gender composition between the two groups ( χ 2=0.03, P >0.05). Compared to the control group, after controlling for various factors including gender, phase of studying, parental education, whether to live in school, and long term caregivers of the student, the risk of experiencing psychological abuse ( OR=1.43, 95%CI =1.26-1.63) and neglect ( OR=1.53, 95%CI =1.33-1.75) was significantly higher in parentdivorce group ( P <0.05).
Conclusions
Parental divorce significantly impacts psychological abuse and neglect experienced by middle and high school students. Therefore, support and intervention efforts should be intensified for students from divorced or unstable marriage families.

s: The onset of Crohn’s disease (CD) is the interaction of environment, heredity, infection, immune and other factors. It is also closely related to abnormal immune functions. Without special treatment, CD is identified as a modern refractory disease. By syndrome differentiation and treatment, traditional Chinese medicine (TCM) can effectively relieve disease conditions, improve the quality of life and reduce side effects of modern medication. The core compatibility ofBai-Zhu andFu-Ling can reinforce spleen-qi and dispel dampness, which met the common pathogenesis of CD. Therefore, the combination is comprehensively used in the compound prescription. Our previous study found thatBai-Zhu Fu-Ling decoctioncan reduce the vasoactive intestinal peptide (VIP) of animal model of spleen-qi deficiency, downregulate VIP receptors, decrease the affinity of VIP receptors and improve animal model’s sIgA. To further clarify the effects about neurotransmitters and their correlation with the immune system in the pathogenesis of CD and the intervention mechanism treated by different proportional compatibility ofBai-Zhu Fu-Ling decoction, we studied influences of the decoction on related transmitters of nerve- immune network and functions of receptors, as well as cytokine secretion and signal transduction of TLR4-NF-κB. Our studies can provide references and foundations to further explore TCM treatment of CD.

Toll-like receptor 3 (TLR3), as an important pattern recognition receptor (PRR), dominates the innate and adaptive immunity regulating many acute and chronic inflammatory diseases. Atherosclerosis is proved as an inflammatory disease, and inflammatory events involved in the entire process of initiation and deterioration. However, the contribution of TLR3 to atherosclerosis remains unclear. Herein, we identified the clinical relevance of TLR3 upregulation and disease processes in human atherosclerosis. Besides, activation of TLR3 also directly led to significant expression of atherogenic chemokines and adhesion molecules. Conversely, silencing TLR3 inhibited the uptake of oxLDL by macrophages and significantly reduced foam cell formation. Given the aberrance in TLR3 functions on atherosclerosis progression, we hypothesized that TLR3 could serve as novel target for clinical atherosclerosis therapy. Therefore, we developed the novel ellipticine derivative SMU-CX24, which specifically inhibited TLR3 (IC50 = 18.87 ± 2.21 nmol/L). In vivo, atherosclerotic burden was alleviated in Western diet fed ApoE-/- mice in response to SMU-CX24 treatment, accompanying notable reductions in TLR3 expression and inflammation infiltration within atherosclerotic lesion. Thus, for the first time, we revealed that pharmacological downregulation of TLR3 with specific inhibitor regenerated inflammatory environment to counteract atherosclerosis progression, thereby proposing a new strategy and probe for atherosclerosis therapy.
