ABSTRACT

In this study, the underlying mechanism of Qiwei Guibao Granules(QWGB) in the treatment of premature ovarian fai-lure(POF) was explored by the proteomics technique. Firstly, the POF model was induced in mice by intragastric administration of Tripterygium wilfordii glycosides solution at 50 mg·kg~(-1) for 14 days. Ten days prior to the end of the modeling, the estrous cycle of mice was observed every day to evaluate the success of modeling. From the 1st day after modeling, the POF model mice were treated with QWGB by gavage every day and the treatment lasted four weeks. On the 2nd day after the end of the experiment, blood was collected from the eyeballs and the serum was separated by centrifugation. The ovaries and uterus were collected and the adipose tissues were carefully stripped. The organ indexes of the ovaries and uterus of each group were calculated. The serum estrogen(E_2) level of mice in each group was detected by ELISA. Protein samples were extracted from ovarian tissues of mice, and the differential proteins before and after QWGB intervention and before and after modeling were analyzed by quantitative proteomics using tandem mass tags(TMT). As revealed by the analysis of differential proteins, QWGB could regulate 26 differentially expressed proteins related to the POF model induced by T. wilfordii glycosides, including S100A4, STAR, adrenodoxin oxidoreductase, XAF1, and PBXIP1. GO enrichment results showed that the 26 differential proteins were mainly enriched in biological processes and cellular components. The results of KEGG enrichment showed that those differential proteins were involved in signaling pathways such as completion and coalescence cascades, focal adhesion, arginine biosynthesis, and terpenoid backbone biosynthesis. The complement and coalescence cascades signaling pathway was presumably the target pathway of QWGB in the treatment of POF. In this study, the proteomics technique was used to screen the differential proteins of QWGB in the treatment of POF in mice induced by T. wilfordii glycosides, and they were mainly involved in immune regulation, apoptosis regulation, complement and coagulation cascade reactions, cholesterol metabolism, and steroid hormone production, which may be the main mechanisms of QWGB in the treatment of POF.

ABSTRACT

BACKGROUND: Vitamin A deficiency (VAD) has been hypothesized to play a role in the pathophysiology of atopic dermatitis (AD). OBJECTIVE: We sought to verify whether VAD can exacerbate AD development, and explore the possible pathophysiologic mechanism. METHODS: We detected serum vitamin A (VA) concentration in different phenotypes of AD infants (intrinsic AD, iAD and extrinsic AD, eAD), and established ovalbumin (OVA) percutaneous sensitized AD model and passive cutaneous anaphylaxis (PCA) model on VAD and vitamin A supplementation (VAS) model in wild-type mice (C57BL/6) and established AD model on both normal VA (VAN) and VAD feeding mast cell deficiency mice (ckitw-sh/w-sh ). RESULTS: The average serum VA concentration of eAD was significantly lower than that of iAD, as well as healthy controls. In OVA-induced C57BL/6 mouse AD model, compared with VAN group, VAD mice manifested significantly more mast cells accumulation in the skin lesions, more severe Th2-mediated inflammation, including higher serum IgG1 and IgE levels, more IL-4, IL-13 mRNA expression in OVA-sensitized skin, and lower Th1 immune response, including lower serum IgG2a and IFN-γ mRNA expression in the skin. But there was no significant difference in the expression of IL-17 mRNA between OVA-treated skin of VAN and VAD mice. However, in OVA-induced ckitw-sh/w-sh mouse AD model, we did not find any significant differences in the above measurements between VAD and VAN group. In PCA model, VAD mice showed remarkable more blue dye leakage than that in VAN mice. Compared with VAD group, the above-mentioned inflammatory measurements in VAS group and VAN group were similar in OVA-induced AD model mice. CONCLUSIONS AND CLINICAL RELEVANCE: VAD can exacerbate extrinsic AD by augmenting Th2-mediated inflammation and mast cell activation. Therapeutic VAS can rescue VAD-aggravated eAD. It may provide a new strategy for future prevention or treatment of atopic dermatitis.

ABSTRACT

<p><b>OBJECTIVE</b>To search for an effective needling method for treatment of piriformis injury syndrome.</p><p><b>METHODS</b>Eighty-two cases were randomly divided into a three needling group and a routine needling group, 41 cases in each group. The three needling group were treated by acupuncture at Huantiao (GB 30), Yanglingquan (GB 34) and Shenmai (BL 62), with needling shallow, middle and deep layers for Huantiao, Yanglingquan, and after acupuncture massage was given at the Foot-Taiyang Channel and the Foot-Shaoyang Channel on lumbosacral region and the affected foot. The routine needling group were treated by routine needling at Huantiao (GB 30), Juliao (GB 29), Chengfu (BL 36), Yanglingquan (GB 34), massage was given also. Their therapeutic effects were compared.</p><p><b>RESULTS</b>The cured rate was 87.8% in the three needling group and 63.4% in the routine needling group, with a significant difference between the two groups (P < 0.05).</p><p><b>CONCLUSION</b>The therapeutic effect of three needling method on piriformis injury syndrome is better than that of routine needling.</p>

ABSTRACT

<p><b>AIM</b>To investigate the pharmacokinetic course of intranasal powders of Panax notoginseng Saponins (PNS) in a rat model and its protective effects against cardio-cerebrovascular diseases administrated in the form of its suspension.</p><p><b>METHODS</b>After administration, Rgl concentration in the serum was analyzed by HPLC and the absolute bioavailability was calculated. The protective effects against cardia-cerebrovascular diseases were studied on actue myocardial infarction model in rats built by occlusion of left coronary artery and cerebral ischemia-reperfusion model in gerbils built by occlusion of bilateral common carotid artery (CCA).</p><p><b>RESULTS</b>The in vivo course of Rgl in rats conformed to two-compartment model after intranasal administration of PNS suspension and the absolute bioavailability was 103.56%. The suspension significantly reduced myocardial infarct size induced by occlusion of the left coronary artery, alleviated cerebral edema and the stroke symptoms induced by occlusion of bilateral common carotid artery (CCA). And the effects were dose-dependent, the higher dose, the better effects.</p><p><b>CONCLUSION</b>The results of pharmacokinetics and pharmacodynamics demonstrated that PNS intranasal preparation has a pretty prospect to develop.</p>
