The plasma levels of inflammatory cytokine interleukin-6 (IL-6) and anti-inflammatory cytokine interleukin-10 (IL-10) in the patients with unstable angina or stable angina were determined and compared. In 30 patients with unstable angina and 22 patients with stable angina, plasma levels of IL-10 and IL-6 were detected by ELISA and plasma lipid parameters by lipid research clinical methods respectively. The results showed plasma levels of IL-10 were significantly lower in unstable angina group than in stable angina group (P = 0.005), while those of IL-6 were significantly increased in unstable angina group as compared with those in stable angina group (P = 0.039). There was a significantly negative correlation between IL-10 and IL-6 in patients with unstable angina (r = -0.41, P = 0.003). In the unstable angina group, IL-6 levels were obviously positively correlated with TC (r = 0.314, P = 0.023), but not with TG and HDL. There were no significant correlations between IL-10 and plasma lipid parameters. It was suggested that the decreased IL-10 and increased IL-6 might be associated with the atheromatous plaque stability and progression of coronary heart diseases. IL-10 may play an important role in preventing coronary vascular lesions.

OBJECTIVETo observe the effects of low-dose exogenous estrogen nonylphenol (NP) on the proliferation of human prostate cancer cell lines DU-145 and the expression of the membrane estrogen receptor GPR30 in the DU-145 cells.

METHODSWe exposed DU-145 cells to different concentrations of NP for 24 hours, followed by measurement of the half maximal inhibitory concentration (IC50) of the cells by cell proliferation assay and determination of the concentration of exposure to low-dose NP. We also observed the expressions of 3 estrogen receptors (ER), including ER-alpha, ER-beta and membrane estrogen receptor GPR30, in the DU-145 cells exposed to low-dose NP by RT-PCR.

RESULTSCell proliferation assay showed that within a certain range of doses, NP inhibited the proliferation of the DU-145 cells with an IC50 of 46 micromol/L, a much lower dose of NP than IC50, 0.01, 0.1.1 micromol/l NP, that can promote the proliferation of DU-145 cells. The results of RT-PCR indicated that the expressions of the three ERs in the DU-145 cells were similar to those in prostate epithelial cells, and that low-dose NP promoted the expression of GPR30.

CONCLUSIONMembrane estrogen receptor GPR30 may play a role in low-dose NP promoting the proliferation of DU-145 cells.

This study examined the changes of activities of vitamin K-dependent clotting factors (VKDCF) under various pathological conditions and explored the relationship between acquired deficiency of VKDCFs and hemorrhage. Clinical data of 35 patients who were diagnosed as having acquired deficiency of VKDCF were retrospectively analyzed. Coagulation factors involved in the intrinsic and extrinsic pathways were detected in these patients and 41 control subjects. The results showed that the average activities of VKDCFs were decreased in the patients in comparison to the control subjects and significantly increased after treatment of these patients with vitamin K and blood products. Multivariate regression analysis indicated that decreased activity of VKDCF was not an independent risk factor for bleeding disorders owing to deficiency or metabolic disturbance of vitamin K. It was concluded that acquired deficiency of VKDCF occurs under a variety of pathologic conditions and is closely associated with hemorrhagic events. Administration of vitamin K and transfusion of blood products containing high concentrations of VKDCFs helps alleviate the hemorrhagic diseases.

Objective To investigate the clinical and molecular pathological features of dysferlinopathy in China.Methods Four patients with limb-girdle muscular dystrophy2B(LGMD2B)and 4 patients with Miyoshi-type distal muscular dystrophy(MMD)were clinically analyzed, their skeletal muscle were biopsied and immunohistochemical stained.Four cases of each Duchenne-Aran muscular atrophy and myotis were served as controls.Results The clinical situation of dysferlinopathy was characterized by progressive muscle weakness and atrophy, consistent with progressive muscular dystrophy.Histochemical staining revealed muscle fibers degenerating, regenerating and necrosis in a varying degree.Connective tissue was seen proliferated and inflammatory cells infiltrated in the majority of cases.Immunohistochemical staining with anti-dysferlin monoclonal antibody identified the deficiency of dysferlin on the sarcolemma and in the sarcoplasm of 8 cases with dysferlinopathy.Conclusions(1)The clinical and pathological characters of dysferlinopathy are consistent with progressive muscular dystrophy;(2)Anti-dysferlin monoclonal antibody immunohistochemical staining is a reliable method to diagnose dysferlinopathy, which is worth of wide application in clinic.

The metabonomics method was used to study the intervention effect of Psoraleae Fructus and Myristicae Semen in "Ershen pill" on the changes in serum endogenous metabolites in spleen-kidney Yang deficiency diarrhea rats before and after processing, screen out differentiated metabolites related to spleen-kidney Yang deficiency diarrhea and explore the metabolic patterns related to spleen-kidney Yang deficiency diarrhea and the processing synergy mechanism of Psoraleae Fructus and Myristicae Semen in "Ershen pill". Efforts were made to detect SOD and MDA of each group, test rat serum metabolic fingerprints in different stages by using GC-MS, analyze by PCA and PLS-DA methods and screen out potential biomarks through VIP and t test. The results revealed that "Ershen pill" could enhance the level of SOD and decrease the level of MDA and identified 10 differentiated metabolites related to spleen-kidney Yang deficiency diarrhea. Compared with the model group, all of metabolites recovered to varying levels after being intervened with "Ershen pill", with the best effect shown in the "Ershen pill" IV group (salt-processed Psoraleae Fructus + bran-roasted Myristicae Semen). It is speculated that that Psoraleae Fructus and Semen Myristicae in "Ershen pill" show a synergistic effect by inhibiting peroxide, improving aglucolipid, amino acids and energy metabolism, with multiple target sites.

AIM AND METHODSUsing double immunohistochemical method for Fos and tyrosine hydroxylase(TH) to examine the effects of intracerebroventricular (icv) administration of adrenomedullin (AM) on catecholaminergic neurons and the expression of c-fos gene in rat brain nuclei involved in cardiovascular regulation in order to define whether the effects of central administration of adrenomedullin (AM) were induced by activating the catecholaminergic neurons.

RESULTS(1) Following icy administration of AM (3 nmol/kg), Fos-like immunoreactivity neurons were markedly increased in several brain areas of the rat, including the brainstem, the hypothalamus and the forebrain. (2) Following icy administration of AM (3 nmol/kg), double-labeled neurons for Fos and TH increased significantly in the area postrema (AP), the nucleus of the solitary tract (NTS), the nucleus paragigantocellularis lateralis (PGL) and the locus coeruleus (LC). (3) Pretreatment with calcitonin gene-related peptide receptor antagonism CGRP (8-37) (30 nmol/kg) significantly reduced the action of AM (3 nmol/kg) in the brain.

CONCLUSIONAM activates the nuclei involved in cardiovascular regulation in the forebrain, the hypothalamus and the brainstem, and that the central actions of AM are induced by activating the catecholaminergic neurons of brainstem nuclei involved in cardiovascular regulation. CGRP receptor can mediate the effects of AM in brain.
