OBJECTIVE: To observe the effects of Huayu Tongluo (transforming stasis and unblocking collaterals) moxibustion on learning-memory ability and hippocampal mammalian sterile 20-like kinase 1 (Mst1)/nuclear factor κB (NF-κB) p65 pathway related to inflammatory response in rats with vascular dementia (VD). METHODS: A total of 60 male Wistar rats of SPF grade were randomly divided into a sham operation group (12 rats) and a modeling group (48 rats). VD model was established by the method of modified bilateral common carotid artery permanent ligation in the modeling group. Thirty-six rats with successful modeling were randomly divided into a model group, a moxibustion group and a western medication group, with 12 rats in each group. Huayu Tongluo moxibustion was applied at "Dazhui" (GV14), "Baihui" (GV20) and "Shenting" (GV24) in the moxibustion group, 20 min each time, once a day, 7 day-intervention was as one course, and 1 day-interval was taken between two courses, for a total of 3 courses. In the western medication group, piracetam was given 0.72 mg/kg by intragastric administration, twice a day, the course of intervention was same as that of the moxibustion group. The learning-memory ability was detected by Morris water maze test; the morphology of hippocampal CA1 region was observed by HE staining; the mRNA expression of Mst1, M1 microglia markers CD86, interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) was detected by real-time PCR; the levels of IL-6 and TNF-α in hippocampus were detected by ELISA; and the protein expression of Mst1 and NF-κB p65 in hippocampus was detected by Western blot in rats of each group. RESULTS: Compared with the sham operation group, the escape latency was prolonged in the model group (P<0.05); compared with the model group, the escape latency was shortened in the moxibustion group and the western medication group (P<0.05). The cells in the CA1 region of hippocampus were disordered, cell collapse and irregular nuclei could be observed in the model group; compared with the model group, the cell arrangement in the CA1 region of hippocampus was more regular, and the damage was improved in the moxibustion group and the western medication group. Compared with the sham operation group, the mRNA expression of Mst1, CD86, IL-6 and TNF-α, as well as the protein expression of Mst1, NF-κB p65 in hippocampus were increased in the model group (P<0.05). Compared with the model group, the mRNA expression of Mst1, CD86, IL-6 and TNF-α, as well as the protein expression of Mst1, NF-κB p65 in hippocampus were decreased in the moxibustion group and the western medication group (P<0.05). Compared with the sham operation group, the levels of IL-6 and TNF-α in hippocampus were increased in the model group (P<0.05). Compared with the model group, the levels of IL-6 and TNF-α in hippocampus were decreased in the moxibustion group and the western medication group (P<0.05). CONCLUSION Huayu Tongluo moxibustion can improve the learning-memory ability of VD rats, the mechanism may be related to regulating the activation of microglia through Mst1/NF-κB p65 pathway, reducing the release of pro-inflammatory factors i.e. IL-6 and TNF-α, so as to alleviating the damage of inflammatory factors in the hippocampus of VD rats.

Objective:To explore the predictive value of non-high-density lipoprotein cholesterol (non-HDL-C) combined with left ventricular ejection fraction (LVEF) for in-stent restenosis (ISR) in patients with coronary heart disease (CHD).Methods:Clinical data of 476 CHD patients who underwent percutaneous coronary intervention (PCI) at the Affiliated Hospital of Jining Medical University from January 2021 to December 2022 were retrospectively analyzed. All patients underwent postoperative coronary angiography reexamination, and were divided into the ISR group (257 cases) and non-ISR group (219 cases) according to the reexamination results. Baseline data were compared between the two groups. Multivariate logistic regression analysis was used to identify the influencing factors of ISR, and receiver operating characteristic (ROC) curve was applied to analyze the predictive value of non-HDL-C, LVEF, and their combination for ISR.Results:The proportion of complicated hypertension, levels of low-density lipoprotein cholesterol (LDL-C) and non-HDL-C in the ISR group were higher than those in the non-ISR group (all P<0.05), while LVEF and stent diameter were smaller than those in the non-ISR group (all P<0.05). Multivariate logistic regression analysis showed that after adjusting for confounding factors, non-HDL-C and LVEF were independent risk factors for ISR in CHD patients after PCI (all P<0.05). ROC curve analysis indicated that the area under the curve (AUC) of non-HDL-C for predicting ISR in CHD patients was 0.648(95% CI: 0.597-0.698, P<0.05), with a sensitivity of 0.461 and specificity of 0.794; the AUC of LVEF for predicting ISR was 0.628(95% CI: 0.577-0.680, P<0.05), with a sensitivity of 0.452 and specificity of 0.863; the AUC of their combination for predicting ISR was 0.701(95% CI: 0.662-0.781, P<0.05), with a sensitivity of 0.782 and specificity of 0.588. Conclusions:Non-HDL-C, LVEF, and stent diameter are independent risk factors for ISR in CHD patients after PCI. Single detection of non-HDL-C or LVEF has predictive value for ISR, and their combination can improve the predictive efficiency, which has higher clinical application value.

Heat shock factor 1(HSF1)is a core transcription factor in cellular stress response and protein homeostasis maintenance,and is widely involved in biological processes such as cell growth,differentiation,and metabolism.This study aims to design antigenic peptides of the sheep HSF1 protein and prepare polyclonal antibodies through bioinformatics analysis and immunologi-cal techniques,and verify their application effects in sheep lung and testis tissues.Firstly,the se-quence,structure,and evolution of the sheep HSF1 gene were analyzed using bioinformatics meth-ods,and key antigenic epitopes were predicted.Then,suitable peptide fragments were selected for synthesis,emulsified with Freund's complete adjuvant or incomplete adjuvant,and used to immu-nize New Zealand rabbits.The specificity and effectiveness of the antibodies were verified by indi-rect ELISA,Western blot,and immunohistochemistry(IHC)experiments.The results showed that the HSF1 protein is 564 amino acids(aa)in length,with a molecular weight of 60.76 kDa,a theo-retical isoelectric point(pI)of 5.32,and is hydrophilic and unstable.Phylogenetic tree analysis revealed that HSF1 is highly conserved among most members of the Bovidae family,as well as in humans,mice,rats,and other species,but with local site differences.Sheep HSF1 is most closely related to goat HSF1,followed by Canadian bighorn sheep and goral.The phosphorylation sites of sheep HSF1 are predominantly concentrated in the middle and C-terminal regions,which is largely consistent with the predicted results for human HSF1,though some local differences exist.The prepared polyclonal antibodies exhibited a titer of over 1:8000 in recognizing the sheep HSF1 pro-tein,and Western blot experiments confirmed clear bands with consistent molecular weight,indica-ting high specificity of the antibodies.Furthermore,the expression and specific distribution of HSF1 were detected in sheep lung and testis tissues.This study successfully prepared polyclonal antibodies based on the sheep HSF1 antigen peptide and,for the first time,detected the immuno-histochemical distribution of HSF1 in the testis and lung tissues of Argali hybrid sheep.This pro-vides an important tool for further exploring the physiological role of HSF1 in Argali hybrid sheep and its potential applications in stress response,disease prevention,and treatment.
