Objective To explore the intrinsic link between neuro-endocrine-immune (NEI) network and the viscera-state.Methods Using three databases namely TCM database, Chinese pharmacy database and combination of TCM and WM database in China Academic Journals Database, the authors searched and collected NEI-related indicators published on journals for the viscera-state researches. Then a related database was established for data mining. Through analysis of association rules, analysis of the relationship among diseases, syndromes, therapeutic principles, combination of disease and syndrome, and NEI network related indicators were performed for association rules and directional network diagrams.Results Through the association analysis, the authors drew 44 directional network diagrams of high-frequency disease positions, syndromes, therapeutic principles and NEI network related indicators, and obtained 19 association rules. Kidney and liver essence research focused on HPG axis, HPA axis, and HPT axis. Spleen essence research focused on brain-gut peptide related indicators. Heart essence research focused on vascular endothelium function indicators. Pulmonary essence research focused on humeral immunity, ET and TNF-α.Conclusion It was feasible to explore the intrinsic link between NEI network and the viscera-state by using data mining. Differences among study on NEI network of five-organs systems were found, which is of great significance for researches on the essence of the viscera-state.

This study was aimed to observe the effect ofZi-Bu Pi-Yin Recipe (ZBPYR) on the mRNA expressions of NMDA receptor subunits NR1, NR2A, NR2B in different brain regions of spleen-yin deficiency Alzheimer's Disease (AD) model rats. The levels of NR1, NR2A, NR2B mRNA expressions were detected by using RT-PCR method. The results showed that the levels of NR1, NR2A, NR2B mRNA expressions of AD group and spleen-yin deficiency AD group decreased significantly (P < 0.05). The levels of NR1, NR2A, NR2B mRNA expressions of ZBPYR treatment group increased significantly (P < 0.05). It was concluded that the expression levels of NMDAR mRNA in different brain regions of the ZBPYR treatment group increased significantly, which indicated that ZBPYR may up-regulate the protein expressions of NMDAR by increasing the expression levels of NMDAR mRNA, thereby to play the anti-dementia effect.

This study was aimed to explore the mechanism ofZi-Bu Pi-Yin Recipe (ZBPYR) on autophagy and endoplasmic reticulum stress (ERS) to improve spleen-yin deficiency diabetes-associated cognitive decline (DACD). Rats were randomly divided into the control (cont) group, the diabetes (DM) group, the spleen-yin deficiency (pi) group, the spleen-yin deficiency diabetes (piDM) group, and the spleen-yin deficiency diabetes + ZBPYR treatment (ZBPYR) group. The expression of microtubule-associated protein 1A/1B-light chain 3 (LC3Ⅱ), inositol-requiring enzymeα (IRE1α), c-Jun N-terminal kinase (JNK) were observed by western blot. The results showed that the expression of LC3Ⅱ in the DM group, pi group and piDM group decreased compared with the cont group (P < 0.05); and the expression of LC3Ⅱ of the ZBPYR group increased compared with the DM group and piDM group (P < 0.05). Compared with the cont group, the p-IRE1α of the DM group and piDM group, as well as p-JNK1 in the pi group and piDM group were increased (P < 0.05). The p-IRE1α and p-JNK1 of the ZBPYR group were decreased compared with the DM group and piDM group (P < 0.05). It was concluded that ZBPYR improved spleen-yin deficiency DACD by regulating autophagy and ERS.

OBJECTIVE: To determine the protective effects of nourishing spleen yin recipe (Zibu Piyin Recipe, ZBPYR), a compound traditional Chinese herbal medicine, on endoplasmic reticulum (ER) in neuronal cells responding to the stress by using sero-pharmacological method. METHODS: The mouse neuroblastoma cell line Neuro2a cells were treated with tunicamycin (Tm, an inhibitor of N-glycosylation). The ZBPYR-treated cell group was established by incubating cells with ZBPYR serum for one hour and treated with Tm. Reverse transcriptase PCR (RT-PCR) was utilized to detect the mRNA expressions from two genes after treatments, ER molecular chaperone glucose regulated protein 78 (GRP78) and transcriptional factor CCAAT/ enhancer-binding protein-homologous protein (CHOP). Lactate dehydrogenase (LDH) assay was also carried out to determine the LDH leakage from Neuro2a cells after treated with Tm and staurosporine (STS). RESULTS: The ZBPYR-treated cell group at all tested ZBPYR dosages showed significantly reduced expressions of both genes compared with Tm (5 microg/ml) treated control group (P<0.05). Therefore, ZBPYR serum inhibited the expressions of GRP78 and CHOP in mRNA level under ER stress induced by Tm. Different concentrations of ZBPYR serum pretreatment reduced the LDH leakage compared with the Tm and STS groups (P<0.05). Therefore, ZBPYR serum may inhibit the LDH leakage induced by Tm and STS. CONCLUSION: ZBPYR has neuroprotective effects. The mechanisms may be associated with inhibition of ER stress and mitochondrial dysfunction.

This study was aimed to observe changes of key molecular in insulin signaling pathway in the hypothala-mus of rats to explore the mechanism of spleen yin deficiency diabetes-associated cognitive decline (DACD) and Zibu Piyin Recipe (ZBPYR) in order to provide new ideas and new clues for treatment of DACD. Rats were randomly divided into five groups, which were the control (Cont) group, diabetes (DM) group, spleen yin deficiency (pi) group, spleen yin deficiency diabetes (piDM) group and the ZBPYR group. Insulin receptor substrate 1 (IRS-1) serine phos-phorylation levels and protein kinase B (PKB/Akt) serine phosphorylation levels which were involved in the insulin signaling were observed by western blotting in the hypothalamus to determine whether there were insulin signaling obstacles in the hypothalamus of rats. The results showed that the expression of p-IRS-1ser in the DM group, pi group and piDM group was increased compared with the Cont group (P< 0.05); while the p-Akt expression of the DM group and piDM group was decreased (P< 0.05). The expression of p-IRS-1ser in the ZBPYR group decreased compared with the DM group and piDM group (P< 0.05); while the level of p-Akt increased compared with the DM group and piDM group (P < 0.05). It was concluded that insulin signaling was not transduced normally in the hy-pothalamus of the DM group, pi group and piDM group. Insulin resistance may occur in the hypothalamus. And ZBPYR can correct insulin signaling transduction disorder.

This study was aimed to observe different forms of β-amyloid peptide (Aβ) and insulin degrading enzyme (IDE) in the hippocampus and cortex in order to further explore the role of Aβ and IDE on spleen yin deficiency di-abetes-associated cognitive decline (DACD), and the effect of Zi-Bu Pi-Y in method. The rats were randomly divided into five groups, which were the blank control (Cont) group, diabetes (DM) group, spleen yin deficiency (pi) group, spleen yin deficiency diabetes (piDM) group and Zi-Bu Pi-Y in recipe (ZBPYR) group. Soluble and insoluble Aβ in the hippocampus and cortex of rats were extracted by gradient centrifugation, and then measured by ELISA. The ex-pression of IDE was observed by western blot. The results showed that the content of soluble and insoluble Aβ1-42 in the hippocampus and cortex of the DM group and piDM group were higher than the Cont group. The soluble and in-soluble Aβ1-42 content in the hippocampus and cortex of the ZBPYR group were reduced compared with the DM group and the piDM group. The soluble Aβ1-40 in the cortex of the DM group, pi group and piDM group were in-creased compared with the Cont group (P < 0.05). The soluble Aβ1-40 content of the ZBPYR group was decreased compared with the DM group and the piDM group (P < 0.05). The expression of IDE protein was decreased in the hippocampus of the DM group and the piDM group compared with the Cont group (P< 0.05), and the IDE protein level in the hippocampus of the ZBPYR group was increased compared with the DM group and the piDM group (P<0.05). The expression of IDE protein in the cortex of the DM group, pi group and piDM group was lower than the Cont group (P< 0.05). The IDE protein level in the cortex of the ZBPYR group was reduced compared to the DM group (P< 0.05). It was concluded that the increased Aβ1-42 in brain may be a major pathological change of DACD and spleen yin deficiency DACD. The decreased IDE expression may be one of the reasons to induce increasing of Aβ1-42 level. The Zi-Bu Pi-Y in method may decrease the Aβ1-42 content by upregulating IDE protein expression.
