Objective To study the effects of low-frequency transcranial magnetic stimulation (TMS) on rats with seizures induced by lithium-pilocarpine. Methods Rats were randomly divided into five groups and pre-treated with TMS at 75% of the stimulator's maximum output, but at 0 Hz (the sham group), 0.3 Hz, 0.5 Hz, 0.8 Hz and 1.0 Hz, respectively. After stimulation every day for 2 weeks, a model of acute epilepsy was induced u-sing iithium-pilocarpine. Subsequent behavior and the latencies of seizures were observed, and the severity of the sei- zures was quantitatively evaluated for 90 rain. Results The seizure latencies were significantly prolonged in all the other groups relative to the sham group (P<0.05). The prolongation in the 0.5 Hz and 0.8 Hz groups was signifi-cantly greater than in the 0.3 Hz and 1.0 Hz groups. The severity of seizures in the 0.3 Hz and 1.0 Hz groups was not significantly different from that in the sham group, but most of the rats in the 0.5 Hz group and the 0.8 Hz group experienced much lighter seizures, with seizure severity scores significantly lower than those in the other 3 groups. Conclusions Pretreatment with TMS at 0.3 to 1.0 Hz led to a longer latency of seizure onset. 0.5 Hz and 0.8 Hz gave the longest latencies and showed conspicuous antiepileptie effects.

Objective To analyze the clinical characteristics of dengue fever (DF) in Guangzhou Higher Education Mega Center (HEMC) in the year of 2014. Methods A retrospective analysis was carried out in the clinical data of 487 cases of DF patients. Results The incidence of DF accounted for 27.18% ( 527/1939) of the total emergeney fever cases. In 487 DF cases with detailed data, 261 were male, and 226 were female; 312 were young aged, 88 were middle aged, and 87 were old aged. For the systemic symptoms, fever accounted for 87.5%, headache 48.3%, and muscular soreness 47.6%. Cough ( 16.6%) , pharynx pain ( 16.8%) and running nose ( 10.9%) were common in respiratory symptoms; poor appetite ( 14.4%) and nausea ( 10.3%) were common in gastrointestinal symptoms. The abnormal laboratory parameters were mainly shown as WBC count ( 48.25%) and PLT count ( 41.68%) , following by creatine kinase ( CK, 39.49%) , aspartate aminotransferase ( AST, 34.12%) , and lactate dehydrogenase ( LDH, 31.96%) . Less cases had abnormal renal function. The distribution of Chinese medical syndrome types was shown as damp-heat blockage (65.7%), syndrome involving Weifen and Qifen simultaneously (23.6%), and Qi-yin deficiency (10.7%). Conclusion In the year of 2014, DF in Guangzhou HEMC occurred mainly among the youth people, the incidence of male DF was similar to that of the female DF, and DF cases usually have the primary symptoms of fever, aversion to cold, headache and muscular soreness. Bleeding is seldom seen in the DF patients, a few cases are complicated with the damage in the blood, liver and myocardium, and most of them have good prognosis.

Objective To observe the influence of triglyceride(TG),hemoglobin(HGB),total bilirubin(TBIL)and rheumatoid factor(RF)on the results of two kinds of D-dimer detection reagent assay.Methods Five samples were prepared into series with 2,4,6,8 and 10 mmol/L triglyceride by adding fat emulsion.Five samples were prepared into series with 1,2,3,4 and 5 g/L of hemolysis degree by adding hemoglobin solution.Five samples were prepared into series with 20,40,60,80 and 100μmol/L total bilirubin by adding bilirubin standard preparation.Ten samples were prepared into rheumatoid factor levels be-tween 0~150 IU/L by adding rheumatoid factor standard solution.Simultaneously with D-dimer detection reagent and D-di-mer HS detection reagent for testing,each sample was measured two times and the results averaged.Results When TG≤2 mmol/L,the D-dimer reagents without interference,and TG≥4 mmol/L,the D-dimer reagents due to “SD baseline data out of range”couldn’t be detected.TG≤10 mmol/L,for D-dimer HS reagents was without interference.When HGB≥1 g/L, the D-dimer reagents due to“SD baseline data out of range”couldn’t be detected.HGB≤4 g/L,for D-dimer HS reagents was without interference.When hemoglobin levels was equal to 5 g/L,the D-dimer HS reagents test results false increased about 30.4%.With total bilirubin concentration increases,D-dimer and D-dimer HS reagents test results were false increase, showed amplitude by a power law,and the two reagents increased consistency.Preparation a series of pooled plasma of rheu-matoid factor levels in 0~150 IU/L,D-dimer test results reagent falsely elevated levels of rheumatoid factor with a linear correlation (Y=59.31X+50.43,R2=0.998).When RF≤150 IU/L,the D-dimer HS reagents was without interference. Conclusion Triglyceride,hemoglobin,total bilirubin and rheumatoid factor may interfere D-dimer testing process,icterus and severe hemolysis will interfere D-dimer HS testing process.D-dimer HS reagents against interfere exceed D-dimer rea-gents.When D-dimer test results does not match with clinicians determine,the influence ofinterfering substances should be considered.

Objective:To compare the efficacy and safety of Changsulin ? with Lantus ? in treating patients with type 2 diabetes mellitus (T2DM). Methods:This was a phase Ⅲ, multicenter, randomized, open-label, parallel-group, active-controlled clinical trial. A total of 578 participants with T2DM inadequately controlled on oral hypoglycemic agents were randomized 3∶1 to Changsulin ? or Lantus ? treatment for 24 weeks. The efficacy measures included changes in glycosylated hemoglobin (HbA1c), fasting plasma glucose (FPG), 2h postprandial plasma glucose (2hPG), 8-point self-monitoring of blood glucose (SMBG) profiles from baseline, and proportions of subjects achieving targets of HbA1c and FPG. The safety outcomes included rates of hypoglycemia, adverse events (AEs) and anti-insulin glargine antibody. Results:After 24 weeks of treatment, mean HbAlc decreased 1.16% and 1.25%, FPG decreased 3.05 mmol/L and 2.90 mmol/L, 2hPG decreased 2.49 mmol/L and 2.38 mmol/L in Changsulin ? and in Lantus ?, respectively. No significant differences could be viewed in above parameters between the two groups (all P>0.05). There were also no significant differences between Changsulin ? and Lantus ? in 8-point SMBG profiles from baseline and proportions of subjects achieving the targets of HbA1c and FPG (all P>0.05). The rates of total hypoglycemia (38.00% and 39.01% for Changsulin ? and Lantus ?, respectively) and nocturnal hypoglycemia (17.25% and 16.31% for Changsulin ? and Lantus ?, respectively) were similar between the two groups (all P>0.05). Most of the hypoglycemia events were asymptomatic, and no severe hypoglycemia were found in both groups. No differences were observed in rates of AEs (61.77% vs.52.48%) and anti-insulin glargine antibody (after 24 weeks of treatment, 6.91% vs.3.65%) between the two groups (all P>0.05). Conclusions:Changsulin ? shows similar efficacy and safety profiles compared with Lantus ? and Changsulin ? treatment was well tolerated in patients with T2DM.
