Objective To observe the protecting effect of Tongluoningxinfang decoction on human umbilical vein endothelial cells. Methods To cultivate endothelial cells and prepare serum with Tongluoningxinfang decoction and Fufangdanshenwan,cells were randomly separated into 8 groups,normal group,model group,treat group (high dose,medium dose,low dose),control group (high dose,medium dose,low dose). Except normal group,add 30% H2O2 to the other groups,and make endothelial cells damaged models. Add serum with drugs to treat groups and control groups,and test NO,ET-1 and P-selection (Ps) respectively. Result NO of model group was significantly lower than normal group,all treat groups and all control groups. ET-1 of model group was significantly higher than all treat groups and all control groups. Ps of model group was significantly higher than normal group,treat groups (smedium dose,low dose) and control groups (high dose,medium dose). It had no significant difference compared with model group,treat group (high dose) and control group (low dose). Conclusion Tongluoningxinfang decoction has the same influence as Fufangdanshenwan on secretion of vein endothelial cells. Tongluoningxinfang decoction and Fufangdanshenwan all can prevent vein endothelial cells from damage induced by H2O2.

ObjectiveTo investigate the protective effect of tanshinoneⅡA on the expression of S100A1 protein after acute myocardial ischemia injury in rats.Methods Sixty Wistar rats were randomly divided into sham operation group, acute myocardial ischemia model group and tanshinoneⅡA pretreatment group by random number table. The acute myocardial ischemia model was established by thoracotomy and penetration of a thread and occlusion around the root part of the left anterior descending coronary artery, while the sham operation group was established only by thoracotomy and penetration of a thread around the root part of that artery but without occlusion; 3 days before the operation, in the tanshinoneⅡA pretreatment group, intraperitoneal injection of tanshinoneⅡA solution(at a dose of 1.5 mg/kg) was applied, while in the sham and acute myocardial ischemia groups, intraperitoneal injection of an equal volume of saline was given. Myocardial cell apoptosis was detected by the terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling(TUNEL), the levels of serum superoxide dismutase (SOD), malondialdehyde(MDA), creatine kinase(CK), lactate dehydrogenase(LDH) and S100A1 protein were examined and the level of expression of S100A1 protein in myocardial tissue was assayed by immunohistochemical staining and Western Blot.Results Compared with the sham operation group, the myocardial cell apoptosis rate, the contents of MDA, CK, LDH, S100A1 and the level of S100A1 expression in myocardial ischemia group and tanshinoneⅡA pretreated group were significantly increased, while SOD activity was decreased obviously; compared with the myocardial ischemia model group, the myocardial cell apoptosis rate, the contents of MDA, CK, LDH, S100A1 and the level of S100A1 protein expression were significantly reduced〔apoptosis rate:(32.1±4.2)% vs.(72.4±5.4)%, MDA(μmol/L): 9.1±2.2 vs. 17.3±5.2, CK(U/L): 83.3±12.2 vs. 107.5±12.4, LDH (μmol·s-1·L-1): 84.0±16.4 vs. 114.4±16.0, S100A1(μg/L): 37.6±6.0 vs. 78.4±8.6,P<0.05 orP<0.01〕, while the activity of SOD was increased markedly in tanshinoneⅡA pretreated group(kU/L:72.8±10.2 vs. 49.6±8.8,P<0.01). TUNEL staining showed that in the myocardial ischemia model group and tanshinoneⅡA pretreated group, the myocardial cells represented positive staining(brown-yellow in color), irregular in shape with nuclear pyknosis, cell detachment from the surrounding tissue and other characteristics. And in sham operation group,the staining of majority of cells was negative. The results of immunohistochemistry showed that S100A1 protein staining was relatively deep in the myocardial ischemia model group and tanshinoneⅡA pretreated group, and in the latter group, the color of S100A1 protein positive staining was not as deep as that in the former group. Western Blot showed that the S100A1 protein expression in myocardial ischemia model group was 2.8 folds of that of the sham operation group, while the S100A1 protein expression in tanshinoneⅡA pretreated group was significantly decreased compared with that of myocardial ischemia model group(bothP<0.05),which was 1.5 folds of that of the sham operation group.ConclusionTanshinoneⅡA may play a role in inhibiting the expression of S100A1 protein to protect against acute myocardial ischemia injury, suggesting that this agent have a potential effect for treatment of myocardial ischemia.

Objective:
To investigate the antimicrobial resistance in and multilocus sequence typing (MLST) of Campylobacter jejuni in meat and meat products in Liaoning Province, so as to provide insights into the management of C. jejuni infection.
Methods:
Nine C. jejuni isolates from meat and meat products in 2020 were subjected to whole genome sequencing, and the minimum inhibitory concentration was measured with the agar dilution method. MLST of C. jejuni isolates was performed with the microbial resistance mechanism traceability reference database and analysis system.
Results:
Six drug-resistant C. jejuni isolates were detected, and there were four multidrug-resistant isolates. There were six C. jejuni isolates resistant to tetracycline, five isolates resistant to nalidixic acid, four isolates resistant to ciprofloxacin, two isolates resistant to florfenicol, one isolate resistant to gentamicin and one isolate resistant to streptomycin. Nine C. jejuni isolates showed sensitive to azithromycin, chloramphenicol and clindamycin. MLST identified six ST types in nine C. jejuni isolates, with ST45 and ST2274 as the predominant type, and detected one isolate with unclassified ST type. Phylogenetic analysis showed that KW028 and KW029 of ST45 type were closely related and had high homology, and KW040 and KW042 of ST2274 type were closely related with high homology, while KW007 of ST6701 type was closely related to KW040 and KW042 of ST2274 type, with only one pgm housekeeper gene in difference.
Conclusions
High resistance to tetracycline, nalidixic acid and ciprofloxacin was detected in nine C. jejuni isolates from meat and meat products, and ST45 and ST2274 were predominant ST types of C. jejuni.

This study was aimed to determine effect of Bu-Shen Kang-Shuai (BSKS) Tablet on HO-1 mRNA and its associated oxidative stress levels among atherosclerotic rabbits. A total of 56 rabbits were randomly divided into the normal group (8 rabbits) and the experimental group (48 rabbits). Normal diet was given to the normal group. Atherosclerotic rabbits models were established in the experimental group. At the eighth week, rabblits in the experi-mental group were randomly divided into the model group, BSKS Tablet group and simvastatin group. Blood samples were collected before medication, 8-, 12-, 16-week after medication from rabbits of each group. Rabbits were sacri-ficed under aseptic conditions at the last blood collection. Expressions of aortic HO-1 mRNA and PPARα mRNA were measured by Q-PCR method. The level of MMP-9 was measured by immunohistochemical assay. Serum HbCO, COX-2 activity and cGMP level were measured by ELISA assay. The results showed that after the intervention of BSKS Tablet, serum HbCO level decreasd, cGMP was obviously increased. However, there was no obvious change on the COX-2 activity. The immunohistochemical assay showed that BSKS Tablet obviously reduced MMP-9 level of rabbits. There was only small amount of aortic HO-1 mRNA expression in the normal group. However, the expres-sion of aortic HO-1 mRNA in the atherosclerosis group was increased. After intervention of BSKS Tablet, the ex-pression of HO-1 mRNA was increased with statistical significance (P < 0.05). Simvastatin had similar antioxidant effect. It was concluded that the compound preparation of traditional Chinese medicine (TCM) BSKS Tablets had an important antioxidant effect in treatment of atherosclerosis. Its protective mechanism may be through the regulation of HO-1 mRNA gene expression and effects of HO-1/CO-cGMP pathway activities of related enzymes while peroxida-tion stability of atherosclerotic plaque.
