RESUMEN
ObjectiveTo investigate the effect of Ziziphi Spinosae Semen-Albiziae Flos on the nucleotide-binding oligomerization domain，NOD-like receptor thermal protein domain associated protein 1 （NLRP1）/chemokine ligand 1 （CXCL1）/chemokine receptor 2 （CXCR2） pathway in the hippocampus of the rat model of chronic unpredictable mild stress （CUMS）-induced depression. MethodA total of 120 male SD rats were randomized into blank，CUMS，CUMS + low-，medium-，and high-dose （4，8，16 g·kg-1） Ziziphi Spinosae Semen-Albiziae Flos，and CUMS + venlafaxine hydrochloride （0.008 g·kg-1） groups，with 20 rats in each group.The rat model of depression was established by solitary feeding combined with CUMS.The behaviors and spatial learning and memory abilities of rats were examined by sugar water consumption test，tail suspension test，forced swimming test，and Morris water maze test.Quantitative real-time PCR （Real-time PCR） and Western blot were employed to determine the expression of factors associated with the NLRP1/CXCL1/CXCR2 pathway in the hippocampus.Enzyme-linked immunosorbent assay was employed to determine the levels of tumor necrosis factor-α （TNF-α），interleukin （IL）-18，IL-1β，and IL-6 in the hippocampus.The immunofluorescence assay was used to measure the levels of reactive oxygen species （ROS） in the hippocampus. ResultCompared with the blank group，the CUMS group showed decreased preference to sugar water and times of crossing the platform （P<0.01），and increased immobility time of tail suspension，forced swimming floating time，and escape latency （P<0.01）.Compared with the CUMS group，the administration of Ziziphi Spinosae Semen-Albiziae Flos and venlafaxine hydrochloride alleviated the effects of CUMS on the above-mentioned behaviors and spatial learning and memory abilities of the rats （P<0.05，P<0.01）.Compared with the blank group，the CUMS group showed up-regulated protein levels of NLRP1，CXCL1，and CXCR2 （P<0.01） and elevated levels of IL-18，IL-1β，TNF-α，and IL-6 （P<0.01） in the hippocampus.The treatment with Ziziphi Spinosae Semen-Albiziae Flos and venlafaxine hydrochloride attenuated the activation of NLRP1/CXCL1/CXCR2 signaling pathway and lowered the levels of inflammatory cytokines in the hippocampus of CUMS rats （P<0.05，P<0.01）.In addition，Ziziphi Spinosae Semen-Albiziae Flos lowered the level of ROS in the hippocampus （P<0.05，P<0.01）. ConclusionZiziphi Spinosae Semen-Albiziae Flos can mitigate the depressive behaviors of the rat model of CUMS-induced depression by inhibiting the activation of NLRP1/CXCL1/CXCR2 signaling pathway.
RESUMEN
OBJECTIVE:To study the potential targets of Guizhi decoction regulating Ying and Wei based oncorrespondence between formulation and syndromerelationship and reverse molecular docking technology. METHODS:Active ingredients related to Guizhi decoction were obtained by literature retrievals,and PharmMapper Server was used for reverse molecular docking for ac-tive ingredients. The potential receptors of Guizhi decoction were found on the basis of docking scores,then AutoDock Vina was conducted for positive molecular docking test to observe the affinity between the ligand and the receptor molecule. 75 rats were ran-domly divided into normal group,model group,Guizhi decoction high-dose,medium-dose,low-dose groups(12,8,4 g/kg),15 in each group. Except for normal group,rats in other groups were induced for models with disharmony between Ying and Wei. Af-ter modeling,rats were intragastrically administrated once a day,for 5 d. After administration,11β-HSD1 expression levels in adi-pose tissue and muscle tissue of rats were detected. RESULTS:Reverse molecular docking for active ingredients of Guizhi decoc-tion found that 11β-HSD1 was the frequent receptor,and positive docking test confirmed that uralsaponin b,glycyrrhetnic acid and carbenoxolone and so on had higher affinity with 11β-HSD1. Results of animal test showed,compared with normal group,11β-HSD1 expression levels in adipose tissue and muscle tissue in model group were increased (P<0.05);and compared with model group,11β-HSD1 expression levels in adipose tissue and muscle tissue in Guizhi decoction high-dose group were decreased (P<0.05). CONCLUSIONS:Guizhi decoction regulating Ying and Wei has certain correlation with 11β-HSD1,while the reverse molec-ular docking technology can provide a feasible technical way to studycorrespondence between formulation and syndromerelation-ship.

A total of 90 SD rats were randomly divided into the normal group , model group , western medicine group ( Venlafaxine Hydrochloride 0 . 0125 g?kg-1 ) and high , middle and low dosage groups of AJFTF ( equivalent to the crude drug of 10 , 5 , 2 . 5 g?kg-1 ) . Depression model rats were induced by solitary cultiva-tion and chronic unpredictable stress . The learning and memory abilities of model rats were evaluated with the Morris water maze . And the plasma contents of 5-HT and NE were determined by enzyme-linked immunosor-bent assay ( ELISA ) . The results showed that AJFTF ( administered with high , middle and low dosage for 21 days ) significantly shortened the incubation period of the Morris water maze positioning and navigation ( P <0 . 05 or P < 0 . 01 ) , and increased the times of crossing the platform in space exploration ( P < 0 . 05 or P <0 . 01 ) . There was a certain dose-effect relationship . The AJFTF ( high , middle and low dosage ) increased the plasma contents of 5-HT and NE ( P < 0 . 05 ) . It was concluded that AJFTF can improve learning and memory abilities of depression model rats which indicates that AJFTF have potential antidepressant effects . Its action mechanism may be related to increase plasma monoamine neurotransmitter content of 5-HT and NE .
RESUMEN
This study was aimed to reveal the medication patterns of Chinese patent medicine in the treatment of breast hyperplasia based on association rules and clustering of data mining technology. Articles on Chinese patent medicine in the treatment of breast hyperplasia were retrieved from databases. External formulas or those mixed with western drugs were excluded. Terminologies in the selected formulas were standardized. Information was extracted to build excelltables. Association rules analysis and cluster analysis were used to reveal the medication patterns of Chi-nese patent medicine in the treatment of breast hyperplasia with software R2.15.2 and Cytoscape 2.8.3. The results showed that Chinese medicinals with higher frequency in 195 formulas were Radix bupleuri, Rhizoma cyperi, Chinese Angelica, Selfheal, White Peony Root, Trichosanthes kirilowii Maxim et al. Chinese medicinals with lower frequency were Chinese Alangium leaf, Rhinacanthus nasutus et al. The commonly used herbal pairs were Radix bupleuri -Chinese A ngelica, Rhizoma curcumae - Rhizoma sparganii, frankincense - myrrh et al. The strong association rules indicated that Xiaoyaosan, which takes Radix bupleuri and Chinese A ngelica as its core, is the key character of Chinese patent medicine in the treatment of breast hyperplasia. The cluster analysis revealed several Chinese medicine functional modules, such as Fructus forsythiae - Rhizoma smilacis glabrae - Evodia lepta - Chinese mahonia stem - Lignum millettiae et al. It was concluded that the herbal frequency, herbal pairs, strong associa-tion rules and cluster analysis can reveal the medication patterns of Chinese patent medicine in the treatment of breast hyperplasia in order to provide reference evidences in the optimization of clinical treatment for mula and im-provement of therapeutic efficacy.
