Objective: To explore the clinical efficacy of a new drug for acute coronary syndrome (ACS), ticagrelor in treating the patients with acute ST-segment elevation myocardial infarction (STEMI), and to compare the effect between ticagrelor and clopidogrel in order to obtain the prospective information of ticagrelor in clinical practice.
Methods: A total of 307 STEMI patients were divided into 2 groups, Treatment group, the patients received ticagrelor with aspirin, n=157 and Control group, the patients received clopidogrel with aspirin, n=150. With a period of treatment, the major adverse cardiac events (MACE), rate of thrombosis re-formation and routine blood test result were compared between 2 groups.
Results: Treatment group presented the better LVDD, LVEF, platelet level and ST-segment recovery than those in Control group, P<0.05 or P<0.01. Treatment group showed slightly higher rate of side effect such as dififcult breathing and bleeding, while those reaction did not affect the treatment or special management for the patients.
Conclusion: The clinical effect of ticagrelor is similar to clopidogre for improving the platelet level and cardiac function in STEMI patients, while the clinical advantage reported in abroad should be further studied.

Objective To explore the clinical diagnosis and treatment of cyclic vomiting syndrome in children.Methods Thirty children proved with cyclic vomiting syndrome admitted from January,1998 to January,2003 were analyzed retrospectively.Results Cyclic vomiting syndrome was most likely to occur in 3-12 years old.The male to female ratio was 3∶2.The clinical manifestations were recurrent vomiting.Twenty-one cases had inducements,while 9 cases had not inducements.It was safe and efficient that curing cyclic vomiting syndrome with cyprohetadine and amitriptyline.Conclusions If these children with cyclic vomiting syndrome are inefficient to treatment,excluding metabolizable diseases,gastrointestinal,neurological diseases,they may be diagnosed cyclic vomiting syndrome,and cured with cyprohetadine and amitriptyline.

Objective To discuss the pathogenesis,diagnosis and treatment of delayed traumatic intracerebral hematoma.Methods The clinic data of traumatic delayed intracranial hematoma patients in this hospital were retro- spectively analyzed.According to clinic observation and CT re-examination,47 cases were diagnosed as delayed trau- matic intracranial hematoma(45 cases by operative treatment,and the other 2 by conservative treatment).Results There were 21 cases of recovery,10 cases of slight disability,8 cases of severe disability,8 cases of death.The total mortality rate was 17 %.Conclusion Brain contusion,subarachnoid hemorrhage and skull base fracture were impor- tant factors of DTICH.Fine-observation and prompt CT re-examination offered excellent results for DTICH.

Objective To investigate the effects of aggressive dosing of atorvastatin on the expression of SOCS1 in CD4 + Tlymphocytes from patients with unstable angina pectoris during peri-operative period of PCI.Methods A cohort of 50 patients with unstable angina pectoris were randomized (random number) to give pretreatment with either an aggressive dose (80 mg/d,n =25) or a routine dose (20 mg/d,n =25)of atorvastatin.Circulating CD4 +T cells were subsequently obtained prior to PCI,and also 18 h to 24 hours after PCI,using a magnetic cell sorting system (MACS).Fluorescence-based quantitative real-time polymerase chain reaction (qRT-PCR) was used to measure expressions of SOCSI mRNA in the isolated CD4 + Tlymphocytes,and western blot analysis was used to detect levels of SOCS1 protein.Serum levels of IFN-γwere quantified using enzyme-linked immunosorbent assays (ELISAs).Results Compared with routine dose group,the expressions of SOCS1 mRNA and protein levels were dramatically increased and those were higher in aggressive dose group following PCI (P ＜ 0.05).In contrast,serum levels of IFN-γsignificantly increased following PCI in both groups,but it was higher in routine dose group than in aggressive dose group (P ＜ 0.05).Conclusions Treatment with aggressive dosing of atorvastatin reduced the post-PCI myocardial inflammatory response in patients with unstable angina pectoris,possibly modulating by up-regulating SOCS1 expression in CD4 + Tlymphocytes.

To discover novel fluoroquinolone lead compounds as possible anti-infective or/and antitumor chemotherapies, combination principle of pharmacophore-based drug design, a series of novel tricyclic fluoroquinolone title compounds, [1,2,4]triazino[3,4-h][1,8]naphthyridine-8-one-7-carboxylic acid derivatives ( 5a-5p), were designed and synthesized with a fused [1,2,4]-triazine ring unit. Their structures were characterized by spectral data and elemental analysis and the in vitro antibacterial and anti-cell proliferation activities were also evaluated. The results showed that the titled compounds exhibited more significant inhibitory activities against drug-resistant bacteria (Methicillin-resistant Staphylococcus aureus and multi drug-resistant Escherichia coli strains) and three tested cancer cell lines (human hepatoma SMMC-7721, murine leukemia L1210 and human murine leukemia HL60 cells). Interestingly, SAR showed that compounds with electron-donating groups attached to benzene ring had stronger antibacterial activity than antitumor activity, but electron-withdrawing compounds displayed more potential antitumor activity than antibacterial activity, especially antitumor activity of nitro compounds was comparable to comparison doxorubicin. Thus, novel triazine-fused tricyclic fluoroquinolones as potent anti-infective or/and antitumor lead compounds are valuable to pay attention and for further development.
