Effect of ozonized saline on signaling passway of Keap1-Nrf2-ARE in rat hepatocytes / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To study the effect of ozonized saline on the activation of the Keap1-Nrf2-ARE signaling pathway in rat liver cells.</p><p><b>METHODS</b>Twenty male Sprague-Dawley rats were randomly divided into ozonized saline (OS) group, model group, ozonized saline control (OSC) group and normal control (NC) group. The rats in OS group and model group were intravenously administered with OS or oxygen saline (5 ml/kg) respectively, once a day for 15 days, and then intraperitoneally injected with CCl4 dissolved in oliver oil. The rats in OSC group were pretreated with OS for 15 days. The rats in NC group were fed normally for 15 days. On the 16th day, the rats in OSC group and NC group were intraperitoneally injected with oliver oil (2 ml/kg) without CCl4. After 24 hours of CCl4 or olive oil intraperitoneal injection, the serum levels of alanine transaminase (ALT) and aspertate aminotransferase (AST) were measured. The liver tissues were also collected for detection of total anti-oxygen capability (TAOC), glutathione (GSH), catalase (CAT), Glutathione peroxidase (GPx). Western Blot was used to detect Nrf2 and immunofluorescence staining assay to display intracelluar distribution of Nrf2.</p><p><b>RESULTS</b>Compared with the rats in model group,the serum ALT and AST levels of rats in OS group were significantly lower (P < 0.01) ,which were (1240.4 ± 188.2) U/L and (1245.4 ± 176.9) U/L vs (539.8 ± 175.3) U/L and (546.0 ± 130.2) U/L, and the TAOC, CAT, GPx and GSH activity of rats in OS group were significantly higher, which were (0.72 ± 0.24) U/mg, (1.05 ± 0.21) mg/g, (676.9 ± 115.1) U/mg and (45.2 ± 14.3) U/mg vs (1.37 ± 0.19) U/mg, (2.23 ± 0.55) mg/g, (1024.6 ± 162.9) U/mg and (68.2 ± 9.9) U/mg, respectively. In contrast with NC group, pretreatment of OS in OSC group elevated TAOC, CAT, GPx and GSH activity (P < 0.01 or P < 0.05). Ozonized saline can strengthen the Nrf2 expression in liver cells.</p><p><b>CONCLUSION</b>Preconditioning injection of ozonized saline can reduce rat's liver injury induced by CCl4. The ozonized saline, as a novel Nrf2 activator, can reduce the oxidative damage of radical oxygen species (ROS) and the deleterious substance by activating the Keap1-Nrf2-ARE signaling pathway and its downstream genes expression.</p>

Study on the tongue manifestations for the blood-stasis and toxin syndrome in the stable patients of coronary heart disease / 中国结合医学杂志

<p><b>OBJECTIVE</b>To explore the tongue manifestations for the blood-stasis and toxin syndrome in the stable patients of coronary heart disease (CHD) according to the acute cardiovascular events (ACEs) in one-year follow-up which based on the pathogenesis hypothesis of "blood-stasis and toxin causing catastrophe".</p><p><b>METHODS</b>Totally 254 stable CHD cases were enrolled after diagnosed by coronary angiography, their tongue appearances were recorded by the digital camera of uniform type, 29 cases with ACEs during one-year follow-up were assigned in ACEs group. The non-ACEs were matched in proportion of 2:1 according to the gender, age (±2.5 years), diabetes mellitus history and previous acute coronary syndrome hospitalization history in the non-ACEs group, and 54 cases were eligibly included. The differences of tongue appearance between the ACEs and non-ACEs group were compared.</p><p><b>RESULTS</b>Fifteen cases manifested with bluish tongue (including bluish-grounding or bluish purple tongue), among which 11 cases (37.9%) in the ACEs group and four cases (7.4%) in the non-ACEs group, and there was significant difference (P<0.002). Twenty six cases showed yellow tongue coating in the non-ACEs group, which was significantly higher than that in the ACEs group (48.1 vs. 10.3%, P=0.001). The tongue of sticky greasy coating was more frequently occurred in the non-ACEs group than that in the ACEs group (66.7% vs. 41.4%, P=0.026). The proportion of purplish-red sublingual vessel was higher in the ACEs group than that in the non-ACEs group (41.4% vs. 20.4%, P=0.041). Odd ratio (OR) analysis showed that the patients with bluish tongue, purplish-red sublingual vessel, dry-greasy or dirty greasy coating were more likely to experience ACEs during one-year follow-up (OR: 11.67, 95%CI: 3.34 year 3.34-40.81, P<0.001; OR: 2.76, 95%CI: 1.02 1.02-7.44, P<0.05; OR: 3.12, 95%, CI: 0.89 0.89-10.92, P=0.066).</p><p><b>CONCLUSIONS</b>The bluish tongue (including bluish-grounding or bluish purple tongue) and purplish-red sublingual vessel were potential tongue manifestations of blood-stasis and toxin. The tongue coating changing from sticky greasy to dry greasy or dirty greasy was also probably a tongue manifestation of "transforming toxin", which need demonstration by further study.</p>

Relationship between Chinese medicine syndrome and serum level of high-sensitivity C-reactive protein in patients with stable coronary heart disease / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To study the relationship between Chinese medicine syndrome and serum level of high-sensitivity C-reactive protein (hs-CRP) in patients with stable coronary heart disease (CHD).</p><p><b>METHODS</b>Serum hs-CRP level was determined in 346 patients with stable CHD, whose diagnoses were confirmed by coronary angiography, and the correlation between patients' syndrome and serum hs-CRP level was analyzed.</p><p><b>RESULTS</b>In all the CHD patients enrolled, the most commonly encountered Chinese medicine complex syndromes were the qi deficiency and blood-stasis syndrome, the yang deficiency and blood-stasis syndrome, and the qi deficiency with blood-stasis and turbid phlegm syndrome; the dominant syndrome types were blood-stasis, qi deficiency and phlegm-turbidity, which revealed in 324 patients (93.6%), 189 patients (54.6%) and 140 patients (40.5%), respectively. Comparisons of hs-CRP level between different complex syndromes and syndrome elements showed no significant difference (P > 0.05). However, for patients with phlegm-turbidity syndrome, the hs-CRP level was much higher in patients tended to heat than in those tended to cold (2.23 +/- 2.12 mg/L vs 1.59 +/- 1.27 mg/L, P < 0.05). Besides, the score of blood-stasis syndrome showed no correlation with hs-CRP level (Person correlation coefficient: 0.069, P = 0.203).</p><p><b>CONCLUSION</b>The elevation of hs-CRP level is closely cor related with phlegm-heat syndrome in stable CHD patients. As an inflammatory biomarker, hs-CRP may be regarded as one of the microcosmic indices of toxin in Chinese medicine, which provides an objective evidence for the pathogenesis hinge of accumulated heat to transform toxin, so it is worthy of further study.</p>

Osteoblastic differentiation and gene expression profile change in rat bone marrow mesenchymal stem cells after a single period of mechanical strain / 华西口腔医学杂志

<p><b>OBJECTIVE</b>To evaluate the osteoblastic differentiation and compare the difference in the gene expression of rat bone marrow mesenchymal stem cells (MSCs) affected by a single period of mechanical strain.</p><p><b>METHODS</b>Bone marrow MSCs were harvested from the femurs and tibiae of SD rats and cultured in vitro. A four-point bending apparatus were used to perform a single 40-minute period of 2,000 microepsilon mechanical strain on these MSCs. The proliferation of the MSCs was tested by MTT on scheduled date, and the osteoblastic differentiation of the MSCs was measured by testing the expression of osteocalcin and alkaline phosphate (ALP) activity of these cells. In addition, we have investigated the possible mechanisms underlying the action of the single 40-minute period of 2,000 microepsilon mechanical strain on these MSCs, after profile blotted and handled by bioinformation, the gene expressions of these two periods of MSCs were examined.</p><p><b>RESULTS</b>The MSCs have grown well in vitro. Our experiment showed that mechanical environment did not weaken the proliferation of the MSCs. However, the ALP activity and the expression of osteocalcin were significantly up-regulated by the 2,000 microepsilon mechanical strain. Using the 27 K Rat Genome Array, 416 different expressions were found. The rate of different genes was 2.8%, of which the expressions of 247 genes increased (61 genes remarkably increased) and 169 genes decreased (74 genes remarkably decreased) in these two periods of MSCs.</p><p><b>CONCLUSION</b>Mechanical strain induced the osteoblastic differentiation of the MSCs, which may be attributed to the different gene levels.</p>
