Objective To observe the initial therapy outcomes of Valproic acid for childhood absence epilepsy (CAE),and to assess its therapeutic reaction and short-term prognosis,and to investigate the risk factors for initial therapy failure.Methods From January 2010 to December 2015,absence seizures as key words were used to search CAE in the video-electroencephalogram(VEEG) database of Children's Hospital Affiliated to Nanjing Medical University.Sixty-seven children fulfilled the CAE diagnosis criteria of International League Against Epilepsy in 1989.These patients were separated into 2 groups based on the therapy outcome after 6 months,including seizure control failure group and seizure control group.The patients' clinical characteristics and VEEG characteristics were reviewed.The gender,age of seizure onset,a family history of epilepsy or febrile seizures (FS),consistent with 2005 Panayiotopoulos diagnostic criteria,and VEEG findings were analyzed to evaluate the predictive ability of independent variables and the relationship between these features and treatment outcomes by using a stepwise multivariate Logistic regression model.Results The age at seizure onset was (5.89 ± 2.91) years old,and follow up duration was 6 months.Approximately 23 cases (34.3％) of CAE patients had poor response.No statistical correlation was made for gender,age at onset,the occurrence of generalized tonic clonic seizures,and family history of FS or epilepsy between 2 groups (all P ＞0.05).Compared with seizure control group,patients of the seizure control failure group had significantly higher rates of focal epileptic discharge (87.0％ vs.6.8％),higher rates of intermittent photic stimulation (IPS) induced seizures (52.2％ vs.6.8 ％),fewer rates of occipital intermittent delta activity (8.7 ％ vs.77.3 ％),and fewer rates of patients met the new diagnostic criteria proposed by Panayiotopoulos in 2005 (8.7％ vs.88.6％) (all P ＜ 0.001).The presence of occipital intermittent rhythmic delta activity during wake stage and the interictal focal epileptiform discharges on VEEG during sleep stage were significantly associated with the therapy outcomes in a multivariable Logistic regression analysis (OR =133.714,P ＜ 0.05;OR =0.068,P ＜ 0.05).Conclusions The presence of focal epileptiform discharges,and a typical absence induced by IPS are important factors for first-drug treatment failures with CAE,and conversely the occipital intermittent rhythmic delta activities have a good efficacy.There is no statistical correlation between clinical characteristics and treatment outcomes.

Objective:To evaluate the value of ultrasound-guided transperineal systematic prostate biopsy(SPB)and cognitive fusion multi-parameter magnetic resonance imaging(mpMRI) suspicious transperineal targeted biopsy(CFTB) in the prostate cancer with different serum prostate specific antigen(PSA) levels.Methods:A retrospective analyses were performed in 527 patients with suspected prostate cancer who underwent ultrasound-guided SPB from January 2018 to December 2019 in Shanghai Jiaotong University Affiliated 6th People′s Hospital. According to the PSA levels, they were divided into group A(PSA 4-10 μg/L) and group B(PSA>10 μg/L). All the patients underwent ultrasound-guided SPB, 376 patients with suspicious mpMRI had two additional targeted biopsies. The detection rates of ultrasound-guided SPB and CFTB in prostate cancer were tested by χ 2 test. Compared with pathological results, the sensitivity, specificity, accuracy of two methods were calculated and tested by χ 2 test, and a P<0.05 was defined as statistically significant difference. Results:Prostate cancer was detected in 319 of 527 patients(60.5%). One hundred and three cases of 198 patients in group A were diagnosed as prostate cancer, with an overall detection rate was 52.0%. Among them, ultrasound-guided SPB detected 72 cases of prostate cancer, the detection rate was 36.4%, sensitivity was 67.9%, specificity was 17.7%, accuracy was 26.5%, the detection rate, sensitivity, specificity and accuracy of CFTB were 39.9%, 75.6%, 91.6% and 88.8%, respectively. In this group, there were no statistically significant differences in the detection rate and sensitivity of the two methods in the diagnosis of prostate cancer (χ 2=0.525, 0.005, both P>0.05), and the differences in specificity and accuracy were statistically significant (χ 2=108.340, 79.829, respectively, both P<0.05). Two hundred and sixteen cases of 329 patients in group B were diagnosed as prostate cancer, with an overall detection rate was 65.7%. Among them, 160 cases of perineal prostate cancer were detected by ultrasound-guided SPB, with the detection rate was 48.6%, sensitivity was 78.2%, specificity was 37.6% and accuracy was 49.5%. A total of 189 cases of prostate cancer detected by CFTB, the detection rate was 57.4%, the sensitivity was 89.3%, the specificity was 90.6%, and the accuracy was 90.2%. All the differences were statistically significant in group B(χ 2=5.131, 4.391, 61.339, 38.982, all P<0.05). Conclusions:When PSA is greater than 10 μg/L, CFTB has a higher diagnostic efficiency than SPB.When PSA is 4-10 μg/L, there are no significant differences between the two methods in the detection rate and sensitivity of prostate cancer.

Objective To explore the value of strain rate and dobutamine stress echocardiography(DSE) in the diagnosis of coronary heart disease. Methods High-dose DSE was performed in 18 patients with coronary heart disease and 10 healthy persons, proved by selected coronary angiography. Ten patients had single coronary lesion, and the other 8 patients had more. By strain rate technology, systolic peak strain rate(SR_ SYS ) was measured in 12 segments of healthy persons and ischemic segments of patients. Results SR_ SYS of healthy subjects enhanced by the increasement of dose of DSE. In patients with single coronary lesion, SR_ SYS enhanced on the first states of baseline, 10 and 20 ?g?kg -1 ?min -1 ,while SR_ SYS changed non-significantly on 30 ?g?kg -1 ?min -1 , and began to decrease on 40 ?g?kg -1 ?min -1 . However in patients with more than one coronary lesions, SR_ SYS of 10 ?g?kg -1 ?min -1 became larger than that of baseline, while SR_ SYS didn't increase any longer on 20 ?g?kg -1 ?min -1 , and fell significantly on 40 ?g?kg -1 ?min -1 . Conclusions Combining stain rate and DSE to quantify local myocardial motion is valuable to offer many important clinic messages, and improves the diagnosis of coronary heart disease.

Objective To evaluate the changes of the left atrial function in patients with old myocardial infarction(OMI) by strain rate imaging(SRI). Methods The velocity of the left atrial lateral wall and atrial septum was measured by SRI in 30 patients with OMI(OMI group) and 25 normal subjects (control group). Left atrium passive eject volume index(LAPEVl) and left atium active eject volume index (LAAEVI) were measured using Simpson method. Results ①Compared with the control group, the velocity of the left atrium was reduced obviously in ventricular systole and early ventricular diastole in OMI group(P<0.05) ,but was increased in late ventricular diastole(P<0.05). ②Compared with the controls, LAAEVI was increased significantly in OMI group, but LAPEVI was decreased signicantly(P <0.001). Conclusions SRI could be used to evaluate the left atrial function accurately in patiens with OMI.
