OBJECTIVE: To study the mechanism of Qushi Huayu Decoction (QHD), a compound of traditional Chinese herbal medicine, in prevention and treatment of non-alcoholic steatohepatitis (NASH). METHODS: Thirty-five Wistar male rats were randomly divided into normal group, untreated group, QHD group and Ganle (diisopropylamine dichloroacetate) group. The rats except those in normal group were subcutaneously injected with carbon tetrachloride (CCl(4)) for 4 weeks (twice per week) and simultaneously fed with high-fat and low-protein diet for 2 weeks to induce NASH. Then, the rats were administrated with QHD, Ganle, or distilled water for 2 weeks, respectively. After harvest, alanine aminotransferase (ALT) activity and tumor necrosis factor-alpha (TNF-alpha) content in serum as well as triglyceride (TG) and free fatty acid (FFA) in liver tissue were evaluated, and relativity analysis among these parameters was performed. Cathepsin B (Ctsb), phospho-inhibitor kappa B (P-IkappaB), TNF-alpha protein expressions in liver tissue were assayed with western-blot. The expression and distribution of ctsb in liver tissue were observed with immunohistochemical method. RESULTS: The contents of TG, FFA and activity of ALT were significantly decreased in QHD group. While in the Ganle group, only the activity of ALT in serum was decreased significantly. Expressions of Ctsb, P-IkappaB and TNF-alpha proteins in liver tissues and serum TNF-alpha level were all enhanced in untreated group which, however, were significantly inhibited in the QHD group. And as expected, there were significant relativities among contents of TG in liver tissues and the content of FFA in liver tissue and activity of ALT in serum, content of TNF-alpha in serum and content of FFA in liver tissue and activity of ALT in serum. CONCLUSION: The inhibiting effects of QHD on fat deposition and inflammation in liver are related with its inhibition on the "FFA-Ctsb-TNF-alpha" pathway of lipo-toxicity.

Objective To explore mRNA and protein expression of PAl-1 in kidney tissue of mice with IgA nephropathy (IgAN) and the effects of YiShen Decoction. Methods The IgAN model was built by the method of oral intake of bovine serum albumin(BSA)together with the injection of staphylococcus enterotoxin B(SEB)through caudal vein. The mRNA expression of PAI-1 was measured by fluorescent quantitative polymerase chain reaction (FQ-PER)and the expression of PAI-1 protein was measured by immunohistochemistry. Results No significant difference of mRNA and protein expression of PAI-1 was found between the low concentration and high concentration Yishen Decoction group. But the secretion and mRNA expression of PAI-1 in the low and hiigh concentration Yishen Decoction group was decreased more than that in the IgAN model group. Conclusion The abnormal expression of PAI-1 mRNA and protein played an important role in the onset and development of IgAN. The TCM Yishen Decoction could reduce the abnormal expression of the mRNA and protein of PAI-1 in kidney tissue of mice with IgA nephropathy.

Objective:To evaluate the safety and efficacy of antiplatelet therapy of ticagrelor on patients suffering from acute ST segment elevation myocardial infarction undergoing primary percutaneous coronary in-tervention. Methods:In the study, 96 patients suffering from acute ST segment elevation myocardial infarction onset within 12 h undergoing primary percutaneous coronary intervention from May to October in 2013 were randomly divided into ticagrelor group (n=48) and clopidogrel group (n=48) by using the method of random number table. Ticagrelor and clopidogrel antiplatelet treatment were used before and after operation. Their baseline data, coronary artery disease characteristics, platelet count, adenosine diphosphate(ADP)-induced platelet inhibition rate by thrombelastograph after 5 days of treatment, the major adverse cardiovascular events of the follow up for 6 months and bleeding complications were observed and compared in the two groups. Re-sults:The differences between the two groups of patients with their baseline data, the features of coronary ar-tery lesions, platelet count before and after 5 days of treatment had no statistical significance (P>0. 05). ADP induced platelet inhibition rate [(80. 2 ± 10. 7)%] after 5 days of treatment in ticagrelor group was sig-nificantly higher than that in clopidogrel group [(75. 3 ± 12. 1)%, P<0. 05]. The two groups of patients were followed up for 6 months, 8 cases of major adverse cardiovascular events occurred in clopidogrel group, 2 ca-ses of major adverse cardiovascular events occurred in ticagrelor group, and there was significant difference between the two groups (P<0. 05). The two groups (7 cases of 48 patients in ticagrelor group vs. 3 cases of 48 patients in clopidogrel group ) had no statistically significant difference in bleeding complications ( P>0. 05). Conclusion: Antiplatelet therapy of ticagrelor on patients suffering from acute ST segment elevation myocardial infarction undergoing emergency PCI has good efficacy and safety.

To explore the effects of Qushi Huayu Decoction (QSHYD), a compound traditional Chinese herbal medicine, in prevention and treatment of non-alcoholic fatty liver disease (NAFLD) in rats.

OBJECTIVE To investigate the infection episode and related risk factors in continuous hemodialysis patients. METHODS The relationship among infection and etiologies of infection,nutritional status,pathogens and causes of chronic renal failure(CRF) were retrospectively analyzed in 180 continuous hemodialysis patients. RESULTS Totally 113 times infections were observed among the 86 inpatients under continuous hemodialysis.The main infectious site in hemodialysis patients was lungs.Thirty eight times were positive in 50 times of etiologic detection,Gram-negative germ was the most common(60.3%).Hemoglobin and serum albumin decreased obviously in infectious patients.Diabetes and systemic lupus erythematosus patients were more susceptible to infection.The hepatitis virus infections rate in hemodialysis patients was relatively high. CONCLUSIONS There is higher infections rate in continuous hemodialysis patients.Diabetes and systemic lupus erythematosus patients are more susceptible to infection.Anemia,lower serum albumin,old age and bad compliance are the susceptible factors.

Objective:To investigate the effects of Resolvin D1 (RvD1) on the inflammatory response and the expression of Nod-like receptor protein 3(NLRP3) inflammasomes in mice with acute lung injury.Methods:The 30 male BALB/c mice weighing 25-30 g were divided into 3 groups(each group with 10 mice). Mice in the normal control group were given normal saline by tail vein injection.Mice in the lipopolysaccharide (LPS) group were given the same volume of LPS (10 mg/kg) via tail vein injection.Mice in the RvD1 group were injected with RvD1 (5 μg/kg) through the tail vein 30 minutes prior to LPS administration.Mice were humanely sacrificed after 6 hours.Histopatholo-gical changes of lung tissue, the levels of pro-inflammatory cytokines interleukin(IL)-18 and IL-1β, and the expression of NLRP3 inflammasomes in lung tissue were measured.Results:After LPS administration, the lung of mice showed pathological damage.The levels of pro-inflammatory factors IL-18 and IL-1β as well as the expression of NLRP3, apoptosis-associated speck-like protein containing a card(ASC)and Caspase-1 in the LPS group were significantly higher than those in the normal control group (all P<0.05). After pretreatment with RvD1, the pathological damage of lung tissue was alleviated.The levels of pro-inflammatory factors IL-18 and IL-1β as well as the expression of NLRP3, ASC and Caspase-1 in the RvD1 group were significantly lower than those in the LPS group (all P<0.05). Conclusions:RvD1 can attenuate the pulmonary inflammation in acute lung injury and inhibit the release of pro-inflammatory factors, which is possibly related to the suppression of NLRP3.

OBJECTIVETo study the efficiency and effect mechanism of Herba Artemisiae Scoporiae inhibits the hepatic lipotoxicity model in vitro.

METHODPreparation rat regular serum and medicine serum. Under the safty of medicine thickness by toxicity testing, normal and model groups were added 10% normal rat serum, Herba Artemisiae Scoporiae group was added 10% medicine serum incubation for 24 h, FFA was added to all the groups but the normal incubation for 24 h. The indices were tested below: the content of serum tumor necrosis factor alpha (TNF-alpha) by ELISA, cellular triglyceride content (TG), Oil Red Staining; protein expression of cellular Bcl-2 Assaciated X protein (Bax), phospho-IKB (P-IkappaB) and Cathepsin B (ctsb) by Western Blotting; gene expression of cellular TNF-alpha, Bax and ctsb by real-time PCR; the expression and distribution of ctsb observed by immunofluorescence.

RESULTAfter being incubated with FFA for 24 hours, TG deposition of HepG2 in the model group increased markedly. Compared with normal group, not only the content of serum TNF-alpha, but also the protein expression of cellular ctsb, P-IkappaB and mRNA expression of ctsb, TNF-a increased significantly. Contrast to model group, TG deposition decreased markedly in the Herba Artemisiae Scoporiae group. The Herba Artemisiae Scoporiae inhibited TNF-alpha content, the protein expression of cellular ctsb, P-IkappaB and mRNA expression of TNF-alpha significantly.

CONCLUSIONHerba Artemisiae Scoporiae has a direct inhibition on HepG2 steatosis and TNF-alpha secretion induced by long-chain FFA. The effect mechanism of Herba Artemisiae Scoporiae inhibits the hepatic lipotoxicity has close relationship with inhibition on the protein expression and mRNA expression of ctsb.

OBJECTIVETo explore the association between the ABO blood group and the risk of myocardial infarction in Chinese people.

METHODSWe retrospectively recruited 1 988 consecutive patients with acute myocardial infarction (AMI) and 1 856 non-coronary artery disease (non-CAD) subjects who hospitalized in our hospital between January 2013 and December 2013. The clinical features and ABO blood group were analyzed.

RESULTSBlood group distribution was A (27.1%, 539/1 988), B (34.4%, 684/1 988), AB (10.8%, 215/1 988), O (27.7%, 551/1 988) in patients with AMI and A (26.7%, 496/1 856), B(32.2%, 598/1 856), AB(10.8%, 200/1 856), O (30.4%, 564/1 856) in non-CAD group. The single factor analysis showed that blood group O tended to be more common in the non-CAD group than in AMI group (P = 0.06). After adjustment for common cardiovascular risk factors such as age, gender, hypertension, diabetes, smoking and serum cholesterol level, the A, B, and AB blood groups were associated with increased risk of AMI compared with O blood group, and the difference was significant with A blood group (OR = 1.229, 95% CI 1.019-1.482, P = 0.031) and B blood groups (OR = 1.214, 95% CI 1.017-1.449, P = 0.032). In addition, non-O blood group remained significantly associated with the increased risk of AMI than O blood group after logistic regression analysis (OR = 1.223, 95% CI 1.048-1.426, P = 0.01).

CONCLUSIONOur results suggest that non-O blood group is associated with the increased risk of AMI.
