ALM To study the effects of ginkgo biloba extract (GbE) on expressions of neuron specific enolase (NSE) and S 100 protein(S 100) mRNA in newborn rat brain after hypoxic ischemic brain damage (HIBD) and the mechanism of GbE against HIBD. METHODS The dynamic changes of expressions of NSE S 100 mRNA in brain tissue and effects of GbE were studied using 7 d SD rat hypoxic ischemic brain damage model and RT PCR techniques. RESULTS The peak expressions of mRNA for NSE and S 100 occurred 24 and 48 hours after HIBD respectively, and their expressions decreased gradually. The expressions of mRNA for NSE S 100 in 24, 48, 72 hours were increased after treatment with GbE ( P

OBJECTIVEThe association of metabolic syndrome (MetS) with cardiovascular diseases (CVD) has not been adequately explored in middle-aged and elderly Chinese. This study aimed to investigate MetS' prevalence and its impact on the CVD incidence in this specific population group.
METHODSA data set of a community-based prospective cohort study was analyzed. A total of 2300 subjects aged 40-94 years were followed up for the CVD events. MetS defined according to the JCDCG criteria was assessed at baseline, and the middle-aged and elderly groups were classified by the WHO definition.
RESULTSAs compared with the middle-aged group, the prevalence of MetS increased by 0.6 times (34.6% vs. 21.3%) and the incidence density of CVD increased by 4.9 times in the elderly group (52.3/1000 person-year vs. 8.9/1000 person-year). Furthermore, the multivariate Cox regression revealed that the risk to CVD incidence was independently related to increased waist circumference in the middle-aged group (HR=2.23, P<0.01) and to elevated blood glucose in the elderly group (HR=1.39, P<0.01).
CONCLUSIONMetS was highly prevalent in middle-aged and elderly Chinese. MetS significantly increased the risk to CVD incidence in the elderly. All individuals with metabolic disorders should receive active clinical care to reduce the incidence of CVD.

OBJECTIVETo summarize the clinical characteristics and outcome of patients with long-QT syndrome (LQTs) accompanied with torsade de pointes.
METHODSThirty-two eligible patients were included in this study. Clinical and electrocardiographic data were analyzed and telephone or out-patient follow-up were made in all patients.
RESULTSThere were 15 patients with inherited LQTs (h-LQTs) and 17 patients with acquired LQTs (a-LQTs). There are more women (n = 24) than men (n = 8). β blockers, potassium and magnesium supplement were the basic therapy for h-LQTs patients, bivent pacemaker was implanted in 2 patients and implantable cardioverter defibrillator was implanted in 5 patients. Ventricular tachyarrhythmias and syncope occurred in 4 patients during (39.4 ± 25.1) months follow-up. In 17 a-LQTs patients, one patient with dilated cardiomyopathy died suddenly and another patient with implanted cardioverter defibrillator experienced one ventricular tachycardia during (30.9 ± 13.3) months follow-up.
CONCLUSIONSThe prognosis in h-LQTs and a-LQTs patients with structure heart disease is poor. ICD or CRT-D therapy is suggestive for a-LQTs patients with structure heart disease.

Objective To establish a discriminant model and to provide a relatively accurate scientific basis for the early diagnosis of tuberculosis (TB) and detection of the close contacts. Methods Through logistic regression analysis, key factors were selected according to Bayes theory and key factors of TB incidence of the close contacts were screened as well as a discriminant model was established. Results The non-TB incidence discriminant function of the close contacts was described as: Y1= -39.831 (constant) + 1.927 X, (sputum-frequency) + 3.528 X2 (education) + 0.309 X3 (contact time) + 5.893 X4 (evade) + 2.140 X5 (ventilation) + 8.706 X6 (cough) + 30.970 X7 (fever). The discriminant function of non-TB incidence of the close contacts was as: Y2 =-57.875 (constant) + 2.343 X1 (sputum-frequency) + 3.965 X2 (education) + 0.361 X3 (contact time) + 6.296 X4 (evade) + 1.348 X5 (ventilation) + 12.984 X6 (cough) + 36.555 X7 (fever). Conduslon The diseriminant model night be used to contribute to the early diagnosis, early intervention and timely treatment on those close contacts of tuberculosis cases.

Objective To summarize the clinical characteristics and treatment experience of patients with non-myxomas primary cardiac tumors accompanied with refractory ventricular tachycardia (VT).Methods Clinical and imaging data as well as therapy efficacy and outcome were analyzed in 10 patients with non-myxomas primary cardiac tumors accompanied with refractory VT.Results There were 5 male and 5 female patients in this cohort [ mean age ( 37.6 ± 18.2 ) years ].Palpitation was presented in all 10patients,7 patients experienced syncope,and 2 patients suffered from amaurosis.The diagnosis was made by combined use of transthoracic echocardiogTams,MRI,and CT scan.The time from symptom to diagnosis was (33.2 ± 36.7 ) months.Symptom-related VT was documented by ECG or Holter monitoring.MRI suggested lipoma in 7 patients,lymphoma in 1 patient and fibroma in another patient.Seven tumors were located in the left ventricle,1 in right atria,1 at peri-aortic root and 1 near right ventrieular outflow tract.Nine out of 10 patients received anti-arrhythmic drug therapy.The ventricular tachyarrhythmia disappeared after surgical tumor resection in 4 patients.All other patients who were treated with antiarrhythmic drugs,radiofrequency ablation or subtotal excision showed only suboptimal efficacy during (39.4 ± 25.1 ) months follow-up.Conclusion Surgical tumor removal is the best treatment strategy for the treatment of refractory ventricular tachycardia in patients with primary cardiac benign tumors.

Purpose:
Biomarkers predicting clinically significant prostate cancer (sPC) before biopsy are currently lacking. This study aimed to develop a non-invasive urine test to predict sPC in at-risk men using urinary metabolomic profiles.
Materials and Methods:
Urine samples from 934 at-risk subjects and 268 treatment-naïve PC patients were subjected to liquid chromatography/mass spectrophotometry (LC-MS)-based metabolomics profiling using both C18 and hydrophilic interaction liquid chromatography (HILIC) column analyses. Four models were constructed (training cohort [n=647]) and validated (validation cohort [n=344]) for different purposes. Model I differentiates PC from benign cases. Models II, III, and a Gleason score model (model GS) predict sPC that is defined as National Comprehensive Cancer Network (NCCN)-categorized favorable-intermediate risk group or higher (Model II), unfavorable-intermediate risk group or higher (Model III), and GS ≥7 PC (model GS), respectively. The metabolomic panels and predicting models were constructed using logistic regression and Akaike information criterion.
Results:
The best metabolomic panels from the HILIC column include 25, 27, 28 and 26 metabolites in Models I, II, III, and GS, respectively, with area under the curve (AUC) values ranging between 0.82 and 0.91 in the training cohort and between 0.77 and 0.86 in the validation cohort. The combination of the metabolomic panels and five baseline clinical factors that include serum prostate-specific antigen, age, family history of PC, previously negative biopsy, and abnormal digital rectal examination results significantly increased AUCs (range 0.88–0.91). At 90% sensitivity (validation cohort), 33%, 34%, 41%, and 36% of unnecessary biopsies were avoided in Models I, II, III, and GS, respectively. The above results were successfully validated using LC-MS with the C18 column.
Conclusions
Urinary metabolomic profiles with baseline clinical factors may accurately predict sPC in men with elevated risk before biopsy.
