This article was aimed to study the therapeutic effects and anti-inflammatory effects of Chinese and west-ern medicine ointment on fungal infection animals. Guinea pig models which were infected with Trichophyton rubrum or Microsporum lanosum were applied to observe the effects of antifungal infections on She-Zhi Qin-Xian (SZQX) ointment by transdermal administration. The ointment is the combination of miconazole nitrate, snake oil and Sophora flavescens which is traditional Chinese medicine (TCM). Simultaneously, the models of croton oil-induced mouse ear swelling and carrageenan-induced rat paw swelling were established to observe the curative effect of SZQX ointment. The results showed that the SZQX ointment had a protective role on both guinea pig models. The microscopic scale of localized lesions in infected guinea pigs was significantly decreased (P< 0.01). The effect of SZQX ointment was better than the single using of Chinese or western medicine. The SZQX ointment was also able to significantly reduce the croton oil-induced mouse ear swelling and carrageenan-induced rat paw swelling (P< 0.05, or P< 0.01) with distinct anti-inflammatory effect. And the effect of SZQX ointment was superior to the single using of either Chinese or western medicine. It was concluded that the SZQX ointment had significant antifungal infection and anti-inflam-matory effect.

Qigui Tongfeng tablet (QLTFT) is a traditional Chinese medicine with good effect for treating gout. Here, network pharmacology method and molecular similarity analysis were utilized to study the effective substance basis and molecular mechanism of the QLTFT on the gout. The similarity to the medicinal compounds is reflected in the Tanimoto coefficient that gives the structural similarity of two compounds. Operationally, similar modifiers were described as pairs of concepts with a similarity score of 0. 500. The results of the molecular similarity analysis suggested that the flavonoids in QLTFT could be new leads for gout. Furthermore, complex biological systems may be represented and analyzed as computable networks. Two important properties of a network were degree and betweenness. Nodes with high degree or high betweenness may play important roles in the overall composition of a network. And the results of network analysis showed that dongbeinine, verticinone-N-oxide, verticine N-oxide, peimine, peiminine, isobaimonidine, dongbeirine, peimisine and simi-arenol which with high degree acted on xanthine dehydrogenase/oxidase, matrix metalloproteinase-9, an arachidonate 5-lipoxygenase-activating protein, tyrosine-protein kinase and etc. Inhibition of these targets can prevent the formation of uric acid, reduce inflammation by uric acid and regulate the body's immune response. Thus, these compounds may be the main effective substance basis. The research results not only reveals its molecular mechanism, but also provide a theoretical basis for the quality control of drugs and clinical application.

To clarify the active components in Guizhi Fuling capsule in treatment of intrinsic dysmenorrhea, pelvic inflammation and hysteromyoma, main components were gradually knocked out from the capsules, the effects of knockout capsules on uterine contraction, TNF-α secretion, murine splenocytes (SPL) and hysteromyoma cells proliferation were evaluated, respectively. The inhibition of capsules on uterine contraction was weakened by gradient knockout of paeoniflorin, paeonol, and amygdalin. The suppression of capsulte on TNF-α secretion was reduced by gradient knockout of gallic acid, cinnamaldehyde, pentagalloylglucose, and pachyman. The promotion of SPL cells proliferation was reversed by gradient knockout of gallic acid, paeoniflorin, cinnamaldehyde, quercetin, and pachyman. The depression of capsules on hysteromyoma cells proliferation was attenuated by gradient knockout of paeoniflorin, paeonol, pentagalloylglucose, and albiflorin. In conclusion, the compounds mentioned-above could be the key active basis of Guizhi Fuling capsule in treatment of intrinsic dysmenorrhea, pelvic inflammation and hysteromyoma.

The effects of Guizhi Fuling capsule and its active ingredient combination within different concentration on SPL proliferate were observed by MTT method. The ratio of CD80/86, CD3CD25 and CD3CD69 was used to evaluate cell activation effects of Guizhi Fuling capsule and its active ingredient combination by FCM. Guizhi Fuling capsule with concentration of 400 mg · L(-1)can promote spleen lymphocyte proliferation, as well as the active ingredient combination, which showed the obvious dose-effect relationship. Compared with control group, the difference has statistical significance (P≤0.01). The result of FCM showed that Guizhi Fuling capsule and its active ingredient combination can promote CD80 and CD86 expression on spleen lymphocyte, and also can increase CD25 and CD69 ratio between spleen CD3+ cells. Compared with control group, the difference has statistical significance (P≤0.01). Thus, Guizhi Fuling capsule and its active ingredient combination may have immune-modulate effects, and the mechanism may have a close relationship with the lymphocyte activation.

OBJECTIVETo investigate the therapeutic effect of IL-6 mAb on experimental autoimmune myocarditis (EAM) in rats, and search the mechanism of the role of IL-6, helper T cells 17 (Th17) and regulative T cells (Treg) in EAM pathogenesis.

METHODSThirty-four Lewis rats were divided into three groups randomly, i.e. control group (n = 6), EAM group (n = 12), and IL-6 mAb intervention group (n = 16). Rats in EAM group and IL-6 mAb intervention group were injected intracutaneously with myosin to establish EAM model. Rats in IL-6 mAb intervention group were injected intraperitoneally with 1 mg IL-6 mAb on 1st, 7th to 20th day after cardiac myosin immune injection. Myocardial inflammation was examined by HE stain, Masson stain, and TdT assay (TUNEL reaction) on 21st and 84th day after IL-6 mAb therapy in order to assess the therapeutic role. Spleen cells were analyzed by flow cytometry to illustrate Th17 and Treg cells? number and function. The serum concentration of IL-6, IL-10, IL-17, and TGF-beta in each group was measured by ELISA, concentration of STAT3, RORgammat, and Foxp3 mRNA in each group was determined with RT-PCR. Spleen cells derived from EAM were stimulated by IL-6 mAb in vitro, and the concentration of IL-10, IL-17 and TGF-beta was measured by ELISA.

RESULTSInflammation score, fibrosis score, and apoptosis index in IL-6 mAb intervention group were significantly decreased as compared with those in EAM group (P < 0.01). The number of Th17 and Treg cells in EAM group on the 21st day (experimental acute peak stage) were increased, and those in intervention group on the 21st day were significantly inhibited (P < 0.01). The concentration of serum IL-6, IL-10, IL-17 and TGF-beta in intervention group on the 21st day was decreased dramatically in comparison with that in EAM group on the same day (P < 0.01). The levels of peripheral blood STAT3, RORgammat, Foxp3 mRNA in intervention group on the 21st day was decreased significantly as compared with that in EAM group (P < 0.01). The expression of IL-10, IL-17 and TGF-beta was increased significantly (P < 0.01) by stimulation of IL-6 mAb on spleen cells derived from EAM in vitro.

CONCLUSIONSIL-6 mAb could neutralize IL-6, and ameliorate myocarditis and reduce heart autoimmune responses. IL-6 mAb has significantly protective effects on EAM by suppressing Th17 and Treg cells.

This study was aimed to investigate the effects of high-dose strictosamide injection on cardiovascular sys-tem of anesthetized beagle dogs and to examine the inhibition of strictosamide on ion channels in vitro. Indexes such as changes of systolic blood pressure (Sys), diastolic blood pressure (Dia), mean blood pressure (MBP), heart rate (HR), PR, QRS, QT, QTcb and QTcv at different time points before and after strictosamide injection in dogs were monitored by the polygraph system. The inhibition of strictosamide at different concentrations on hERG potassium channel in CHO-hERG cells and Nav1.5 sodium channel in HEK-293-Nav1.5 cells were measured by whole-cell patch-clamp method. The results showed that compared with the blank control group, Sys, Dia, MBP and HR were obviously declined 15 min after medication in the strictosamide (60, 18 mg·kg-1) group and the vehicle-control group (containing tween-80) (P < 0.05). After medication, all indexes were recovered. Compared to the vehicle-control group, there were no significant differences at different time points in each medication groups. Compared with the blank control group and before medication, the QT interval, QTcb and QTcv were significantly prolonged 15 min af-ter medication in the strictosamide (60, 18, 6 mg·kg-1) group and the vehicle-control group (P< 0.05). When medi-cation stopped, indexes were recovered at certain level. Compared with the vehicle-control group, there were no sig-nificant differences of QT interval, QTcb and QTcv of each medication group at different time points (P> 0.05). The inhibition of strictosamide on hERG potassium channel and Nav1.5 sodium channel were weak with IC50 values of 560.8 μM and > 900 μM, respectively, which were far greater than the positive controls. It was concluded that sin-gle, high-dose intravenous injection of strictosamide may lead to a lower blood pressure, a slower heart rate and a prolongation on the QT interval in beagle dogs, which returned to basal levels when medication stopped. It was spec-ulated that the reduction of blood pressure and the slowing of heart rate were related to tween-80 contained in the vehicle control group. No significant inhibitory effects were detected on hERG potassium channel and Nav1.5 sodium channel in vitro, which suggested that other mechanisms may be involved in strictosamide-induced QT interval pro-longation in animals.

This study was aimed to observe the effects ofTian-ShuDripping Pills (TSDP) on cerebral hemodynamics among anesthetized dogs, in order to demonstrate its clinical treatment functional correlation on angioneurotic headache. A total of 25 hybrid dogs were randomly divided into the normal saline (NS) group, TS capsule (positive control: 0.4 g·kg-1 crude medicine) group, low-dose TSDP (0.2 g·kg-1 crude medicine) group, middle-dose TSDP (0.4 g·kg-1 crude medicine) group, and high-dose TSDP (0.8 g·kg-1 crude medicine) group.Intraduodenal administration was given once under anesthesia. Changes of mean arterial blood pressure, blood flow of vertebral artery and internal carotid artery blood flow were detected and the cerebral blood flow and cerebral vascular resistance were calculated. The results showed that TSDP of low-dose, middle-dose and high-dose group can significantly reduce the cerebral vascular resistance and increase the cerebral blood flow within 180 min after medication. It was concluded that TSDP can improve the cerebral blood circulation of anesthetized dogs. Its mechanism may be through the reduction on cerebral vascular resistance and increasing of cerebral blood flow.
