AIMTo study the mechanisms of sodium ferulate (SF) on inhibition of collagen synthesis in hepatic stellate cells.

METHODSCollagen synthesis was analyzed by measuring 3H-proline incorporation. ELISA method was used to study the effect of SF on transforming growth factor beta1 (TGFbeta1) level in cultured HSC-T6 cell. The effect of SFon the TGFbeta1 activity in the supernatant of culture was analyzed by mink lung epithelial cell (Mv1Lu) proliferation inhibition by MTT assay.

RESULTSSF inhibited collagen synthesis in hepatic stellate cells stimulated with TGFbeta1. SF was shown to decrease TGFbeta1 level in the supernatant of HSC-T6 increased by oxidative stress. TGFbeta1 activity was intervened by SF.

CONCLUSIONSF could decrease collagen synthesis, with mechanism may be associated with that SF intervened TGFbeta1 activity, and reduced the level of TGFbeta1 increased by oxidative stress.

The depositions of immunoglobulins on the retina of diabetic rat were studied with immunohistochemistry,immunofluorecence and computer analysing system.In comparison with control group, depositions of IgG,IgA and IgM on the retina of diabetic rat induced by streptozotocin were significantly increased (all P＜0.05 ).So the immunoglobulin depositions may contribute to the pathogenesis of diabetic retinopathy.

Objective To observe the clinical curative effect of Gubenzhike granule on cough variant asthma (CVA), and explore its mechanism. Methods A total of 140 cases of CVA were randomly divided into two groups, 70 cases for each group. The treatment group took Gubenzhike granule orally, and the control group inhaled Budesonide Powder for Inhalation and Salbutamol Sulphate Aerosol, respectively for 8 weeks, with 8 weeks follow-up after treatment. The same nursing intervention was implemented in two groups. Cough symptom scores of the two groups were observed after treatment and at the end of follow-up, the number of eosnophils (EOS) and content of immunoglobulin E (IgE) in peripheral blood were also observed. Results The treatment group completed 67 cases and the control group completed 66 cases. After treatment, the cough symptom scores, EOS and IgE in two groups were significantly reduced (P<0.01, P<0.05), and the cough symptom score of treatment group decreased more significantly than that of control group (P<0.01). The total effective rate and recurrence rate were 91.04%and 9.84%in treatment group, and 83.33% and 30.91% in control group. The total effective rate of treatment group was better than the control group (P<0.01), and the recurrence rate was lower than the control group (P<0.01). Conclusion Gubenzhike granule showed significant effect and low recurrence rate on CVA. Good anti-inflammatory and antianaphylaxis effects may be one of its mechanisms.

To establish neonatal rat cardiac fibroblast inflammatory secretion model by using LPS 100 microg x L(-1) combined with ATP 5 mmol x L(-1), in order to study the inhibitory effect of quercetin on the secretion of inflammatory factors TNF-alpha, IL-1beta and IL-6 of cardiac fibroblasts, further investigate the effect of quercetin on the protein expression of p-NF-kappaB p65 (S276) and p-Akt (S473) by western blot, and discuss the inhibitory effect of quercetin on the inflammatory secretion of cardiac fibroblasts. According to the findings, quercetin with the concentrations between 51.74 micromol x L(-1) and 827.81 micromol x L(-1) had no significant effect on the activity of cardiac fibroblasts. Quercetin with the concentrations of 82.78, 41.39, 20.70 micromol x L(-1) could notably inhibit the increase of TNF-alpha and IL-1beta induced by LPS 100 microg x L(-1) for 3 h and then ATP 5 mmol x L(-1) for 36 h (P < 0.01 or P < 0.05). Quercetin with the concentrations of 82.78, 41.39 micromol x L(-1) could notably inhibit the increase of IL-6 induced LPS 100 microg x L(-1) for 3 h and then ATP 5 mmol x L(-1) for 36 h (P < 0.05), without any notable effect of quercetin with the concentration of 20.70 micromol x L(-1). Quercetin with the concentrations of 82.78, 41.39, 20. 70 micromol x L(-1) could notably inhibit the NF-kappaB p65 (S276) activation induced by LPS 100 microg x L(-1) for 3 h and then ATP 5 mmol x L(-1) for 15 min, with the most significant effect in 20.70 micromol x L(-1). Quercetin with the concentrations of 82.78, 41.39, 20.70 micromol x L(-1) could notably inhibit the increase of p-Akt(473) expression induced by LPS 100 microg x L(-1) for 3 h and then ATP 5 mmol x L(-1) for 240 min (P < 0.05). Therefore, this study believes that quercetin could attenuate the secretion of inflammatory factors TNF-alpha, IL-1beta and IL-6 of cardiac fibroblasts by inhibiting the activation of NF-kappaB p65 (S276) and Akt (473).

OBJECTIVETo summary the recent advances in molecular research of glioblastoma (GBM) and current trends in personalized therapy of this disease.

DATA SOURCESData cited in this review were obtained mainly from PubMed in English up to 2015, with keywords "molecular", "genetics", "GBM", "isocitrate dehydrogenase", "telomerase reverse transcriptase", "epidermal growth factor receptor", "PTPRZ1-MET", and "clinical treatment".

STUDY SELECTIONArticles regarding the morphological pathology of GBM, the epidemiology of GBM, genetic alteration of GBM, and the development of treatment for GBM patients were identified, retrieved, and reviewed.

RESULTSThere is a large amount of data supporting the view that these recurrent genetic aberrations occur in a specific context of cellular origin, co-oncogenic hits and are present in distinct patient populations. Primary and secondary GBMs are distinct disease entities that affect different age groups of patients and develop through distinct genetic aberrations. These differences are important, especially because they may affect sensitivity to radio- and chemo-therapy and should thus be considered in the identification of targets for novel therapeutic approaches.

CONCLUSIONThis review highlights the molecular and genetic alterations of GBM, indicating that they are of potential value in the diagnosis and treatment for patients with GBM.

OBJECTIVETo investigate the autoimmune injuries of diabetic macrovascular disease (aorta) and the protective effects of immunosuppressive agent (cyclosporine A, CsA) on aortic injuries in streptozotocin (STZ)-induced diabetic rats.

METHODSSTZ-induced diabetic rats were assigned randomly to 6 groups which received low (BML or AML, 1 mgxkg(-1)xd(-1)), middle (BMM or AMM, 4 mgxkg(-1)xd(-1)) or high (BMH or AMH, 8 mgxkg(-1)xd(-1)) dose of CsA from 1 week before or after STZ for 8 weeks. Diabetic rats without any treatment, insulin-treated diabetic rats and normal rats were also monitored simultaneously and served as control groups. The pathologic abnormalities of the aorta were verified by HE, Masson staining and electronmicroscopy. The depositions of immunoglobulins (IgG, IgM and IgA) were determined by immunohistochemistry and immunofluorescence methods.

RESULTSAt the end of study, lymphocytes infiltration and collagen content (26 582 +/- 6901) were significantly higher in diabetic aorta than those in non-diabetic aorta (Collagen: 7482 +/- 3491, P < 0.01). The deposited IgG and IgA were also significantly increased in diabetic aorta compared with non-diabetic aorta (IgG: 11 789 +/- 2491 vs. 2518 +/- 1066, P < 0.01; IgA: 17 430 +/- 3159 vs. 1135 +/- 758, P < 0.01). These changes were not affected by insulin while CsA intervention significantly reduced aortic collagen content (BMH: 13 518 +/- 5440, P < 0.01 vs. STZ) and immunoglobulin deposition (BMH: IgG: 7584 +/- 4462; IgA: 6176 +/- 1900, all P < 0.01 vs. STZ). These immunoglobulin deposition changes were confirmed by results of immunofluorescence. Aortic collagen accumulation was positively correlated to aortic immunoglobulin deposition (IgG, r = 0.556, P < 0.01; IgA, r = 0.661, P < 0.01).

CONCLUSIONSOur data suggest that the autoimmune injuries might be a promoting factor in the pathogenesis of the diabetic macrovascular disease which could lead to the development of macrovascular disease. Immunosuppressive agent, such as CsA, could inhibit the abnormal deposition of immunoglobulins and therefore, delay the development of diabetic macrovascular disease in this model.
