Methods One hundred and twenty patients with UA were randomized into the trimetazidine group (n =60) and the control group (n =60), the trimetazidine group was subjected to treatment with 60 mg trimetazidine everyday for six months plus conventional treatment, and the clinical symptoms, changes in electrocardiogram, changes in the number of plasma circulating endothelial cells (CEC) and endothelin-1 level of the two groups were observed after treatment for four weeks; and the incidence rates of cardiac arrhythmias, cardiac failure, hospitalization due to angina, myocardial infarction and sudden death were also observed after treatment for six months. Results 1) The total effective rate of integrative clinical therapeutic effects in the trimetazidine group and the control group after treatment for four weeks were 86.7% and 68.3%,respectively (P<0.05), and the excellence rates were 36.7% and 15% (P<0.01)respectively; the total effective rates for the therapeutic effects in electrocardiogram were 66.7% and 46.7%,respectively (P<0.05), and the excellence rates were 30.0% and 11.7%, respectively (P<0.01 ). 2) The number of plasma CEC and endothelin-1 level of the two groups after treatment for four weeks significantly decreased (P<0.05), but the decreases in the trimetazidine group were even significant (P<0.01). 3) The incidence rates for cardiac arrhythmia in the trimetazidine group and the control group after treatment for six months were 10% and 20% (P<0.05), respectively, and the incidence rates for cardiac failure were 8.3% and 18.3%, respectively (P<0.05), and the incidence rates for hospitalization due to angina were 10% and 15%, and the incident rates for myocardial infarction were 3.3% and 13.3% respectively (P<0.05). Conclusion Trimetazidine can significantly improve the symptoms of UA and myocardial ischemia, reduce the damages to blood vessel endothelium and complications, and improve the prognosis.

Objective To investigate the effect of Simoyinzi Decoction on serum 5-HT and inflammatory factors in the treatment of perimenopausal women with early onset of severe depression.Methods 82 cases of perimenopausal women with primary severe depression were selected and randomly divided into 2 groups, 41 cases of each group.Control group received basic medicine treatment, the research group received Simoyinzi Decoction treatment,serum neurotransmitter, inflammatory factor and sex hormone levels were detected before and after the treatment, and clinical symptom score and clinical curative effect were compared after the treatment.Results Compared with before treatment, levels of noradrenaline norepinephrine(NE), 5 serotonin(5-HT), dopamine(DA), glutamate(Glu) and N-methyl-D-aspartate(Asp) increased in 2 groups after treatment, levels of gamma amino acid (GABA) and glycine(Gly) decreased, levels of follicle stimulating hormone(FSH) and luteinizing hormone(LH) decreased, levels of estradiol(E2) increased, levels of IL-1β, IL-6, TNF-αand CRP decreased, scores of HAMD and Kupperman decreased, the differences were statistically significant (P<0.05), compared with the control group, levels of NE, 5-HT, Glu and Asp in the research group after treatment were higher, levels of GABA and Gly were lower, levels of FSH and LH were lower, levels of E2 were higher, levels of IL-1β, IL-6, TNF-αand CRP were lower, and scores of HAMD and Kupperman were lower, the differences were statistically significant(P<0.05), and the effective rate in the control group(70.73%) was lower than the research group ( 90.24%) ( P <0.05 ) .Conclusion Simoyinzi Decoction in the treatment of perimenopausal women with early onset of severe depression was curative effective, and it can improve the 5-HT and reduce the levels of inflammatory factors.

The formation of Staphylococcus epidermidis biofilm on the surface of medical biomaterials may resist the antibiotics treatment and cause chronic infection,which has become a research focus in recent years.Multiple genes constitute complex regulatory network which affect the biofilm formation,and play different roles in the different stages of biofilm formation.Accessory gene regulator (agr) is one of the most important genes in the process of biofilm formation.The process of bacterial biofilm formation,research status of regulation mechanism of agr system and its related genes in the formation of biofilm are reviewed,to provide reference of using agr as a target for the treatment of staphylococcus epidermidis biofilm related infections.

Objective To understand the antimicrobial resistance of common clinical pathogens to antimicrobial disks containing different ratios of cefoperazone/sulbactam,so as to provide basis for rational application of cefoper-azone/sulbactam in clinic.Methods 1 141 pathogens isolated from clinical specimens in a hospital in the first half year of 2014 were collected,disk diffusion method was adopted to detect antimicrobial activity of two kinds of cef-operazone/sulbactam disks (70/35 μg and 75/75 μg).Results Of 1 141 pathogenic strains,675 (59.16%)were En-terobacteriaceae,447 (39.18%)were non-fermentative bacteria,and 19 (1 .66%)were other gram-negative bacilli. Resistance rates of pathogens to 70/35μg and 75/75 μg cefoperazone/sulbactam antimicrobial disks were as follows:extended-spectrumβ-lactamases(ESBLs)-producing Escherichia coli (n=221)were 7.69% and 2.26% respective-ly,ESBLs-producing Klebsiella pneumoniae (n=92)10.87% and 3.26% respectively,imipenem-resistant Acineto-bacter baumannii (IRAB,n=295)54.92% and 11 .19%respectively;there were significant differences in antimicrobial activity between two ratios of antimicrobial disks(P <0.05).While antimicrobial resistance rates of ESBLs-negative Enterobacteriaceae (Escherichia coli ,n = 135;Klebsiella pneumoniae ,n =98),imipenem-sensitive Acinetobacter baumannii (ISAB,n=51),Pseudomonas aeruginosa (n=48 ),and Stenotrophomonas maltophilia (n=22)were not significantly different (all P >0.05).Conclusion Antimicrobial activity of two different ratios of cefoperazone/sulbactam antimicrobial disks to ESBLs-producing Enterobacteriaceae and IRAB is different,attention should be paid to ratios of cefoperazone/sulbactam during the treatment ,so as to achieve the desired therapeutic effect.
