Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Jiawei Buzhong Yiqi Decoction (JWBZYQ), from records of FuqingzhuNvke, is a classical formula for treating obese women related infertility. JWBZYQ has been shown to be effective in treating polycystic ovary syndrome (PCOS) in both clinical studies and practical practice, with the pharmacological mechanism remaining unknown. AIM OF THE STUDY To explore the potential therapeutic effects and mechanistic insights of JWBZYQ in PCOS. MATERIALS AND METHODS An overweight PCOS rat model was established via testosterone propionate (TP) injection and 45% high-fat diet (HFD). Then they were categorized into five distinct groups: Control group, Model group, low-dose of JWBZYQ (JWBZYQ1) group, high-dose of JWBZYQ (JWBZYQ2) group, and metformin (Met) group. Body weight, estrous cycle, and sex hormone levels were observed. Hematoxylin-Eosin staining was employed to investigate the histological characteristics of the ovaries. To identify the pathways that changed significantly, transcriptome analysis was performed. The protein and mRNA levels of key molecules in ovarian zona pellucida (ZP) organization, transzonal projections (TZPs) assembly, steroid hormone receptors, and steroidogenesis were assessed using phalloidin staining, immunohistochemistry, Western blot, and polymerase chain reaction. RESULTS RNA-seq analysis demonstrated that regulation of hormone secretion, cilium assembly, cell projection assembly, and ZP production may all have crucial impact on the etiology of PCOS and therapeutic effect of JWBZYQ. In particular, PCOS rats exhibited elevated expressions of ZP1-3, which can be reversed by JWBZYQ2 particularly. Simultaneously, TZPs assembly was totally disrupted in PCOS rats, evidenced by the phalloidin staining, upregulated calcium-/calmodulin-dependent protein kinase II beta (CaMKIIβ), and deficient p-CaMKIIβ, myosin X (MYO10), proline-rich tyrosine kinase 2 (PTK2), and Fascin. Nonetheless, JWBZYQ or metformin treatment revived the disturbance, repairing the oocyte-granulosa cell communication, regulating steroidogenesis in PCOS rats. In this way, JWBZYQ and metformin exerted remarkable effects in alleviating altered ovarian morphology and function in PCOS rats, with JWBZYQ2 revealing the best effect. CONCLUSIONS JWBZYQ restored the altered ovarian morphology and function by regulating the oocyte-granulosa cell communication, which was related with ZP organization and TZPs assembly in the ovary.

Abstract
Pathophysiological process of ethanol physical dependence and its withdrawal syndrome is supposed to result from adaptive changes in a number of neurotransmission systems, and several reports have demonstrated functional relationship between behavioral responses and neurotransmission systems in ethanol-dependent and -withdrawn animals. However, the molecular mechanisms underlying behavioral responses observed in these animals are still controversial at present. Alterations of beta-adrenergic receptor (beta-AR) function in the brains of mice physically dependent on ethanol were examined because of few available data on functional changes of beta-ARs and its significance in ethanol withdrawal signs. The protein level of beta-ARs also significantly increased in the frontal cortex of mouse with ethanol physical dependence and conditions withdrawn from ethanol after chronic treatment with ethanol vapor for 9 days. Intracerebroventricular administration of nadolol, a non-selective antagonist for beta-ARs, immediately after discontinuation of ethanol inhalation clearly attenuated the expression of withdrawal signs. These findings suggests that ethanol physical dependence induces beta-AR up-regulation, that is their increased number and facilitation of beta-AR signaling, which may at least in part participates in expression of tonic-clonic convulsion as one of ethanol withdrawal signs. We further investigated relationship between actin of cytoskeleton and relapse of alcohol dependence after withdrawal from alcohol vapor inhalation for 9 days. After 3 days of withdrawal from alcohol vapor alcohol-induced place preference was enhanced, which was blocked by the treatment with an actin polymerization inhibitor, cytochalasin D, and anactin depolymerization inhibitor, phalloidin, during 3 days after ethanol withdrawal. These findings suggest that changes in actin turnover on withdrawal from alcohol vapor involve in sensitization of alcohol-induced place preference.

Abstract
Acid aspiration leads to pulmonary endothelial and epithelial cell (EC/EpC) injury characterized by increased permeability and polymorphonuclear (PMN) leukocyte diapedesis. Actin in the EC/EpC cytoskeleton has been shown to play a significant role in maintenance of the microvascular junction barrier. This study tests indirectly whether the development of permeability and diapedesis following acid aspiration is via disruption of the pulmonary cytoskeleton. Manipulation was achieved by the actin microfilament assembler phalloidin. Anesthetized rats (n = 88) underwent segmental lung installation of 0.1 ml saline or phalloidin (2 x 10(-6) M). Twenty minutes later 0.1 N HCl, saline, or phalloidin was introduced. After 3 h there was an increase in wet-to-dry weight (W/D) ratio of 6.6 and 5.1 in the HCl-injected and noninjected sides, protein concentration, 3,970 and 2,530 micrograms/ml, and accumulation of 93 PMN/ml (x 10(4] in bronchoalveolar lavage (BAL) of the HCl-injected lung. These values were higher than control animals. Local pretreatment with phalloidin attenuated acid-induced localized but not generalized permeability with reduction in W/D ratio, BAL protein concentration, and diapedesis (P less than 0.05). Acid injection into airways also led to elevated thromboxane B2 and leukotriene B4 levels in plasma and BAL (P less than 0.05) and generalized lung leukosequestration, events not affected by phalloidin. Taken together, these data suggest that acid aspiration lung injury is determined largely by loss of integrity of the pulmonary EC/EpC cytoskeleton with resultant loss of barrier function.
