Objective:To investigate the relation of antiradiation effect of LJP and lymphocyte apoptosis. Methods:36 Wistar rats were randomly divided into 6 groups (n=6): control, model,and LJP given i.g.at 4 doses(100,200,300,400 mg/ kg bw) for 10d before whole-body irradiation with 9.0 Gy Co?-ray. 18h later,the effects of LJP on the indices of immune function of the irradiated rats 60 were measured. TUNEL and flow cytometry were used to study the effects of LJP on splenic lymphocyte apoptosis and immunohistochemical technique was used to detect the expression of Bcl-2 and the Bax protein. Results:LJP significantly modulated immune function in irradiated rats. The apoptosis ratio of splenic lymphocyte of the model group was higher than those of other groups. LJP could markedly inhibit the effects of irradiation on apoptosis and increase the ratio of bcl-2/bax protein in dose-effect manner. Conclusion:LJP could inhibit splenic lymphocyte apoptosis induced by irradiation, and its mechanism is associated with regulating the expression of bcl-2 and bax protein of splenic lymphocyte. Key word:laminaria japonica polysaccharides; irradiation; lymphocyte; apoptosis apoptosis-related genes

Objective To assess the effects of MRI-positive and interictal epileptic charges(IEDs) dominance on the memory of the patients with drug-resistant medial temporal lobe epilepsy (MTLE). Methods Fifty right-handed patients(age ranging from 16 to 60 years old)diagnosed as drug-resistant MTLE in our hospital with normal intelligence between September 2006 and April 2007 were investigated. All patients were classified as left MRI-positive(MRI(+)),right MRI(+),MRI(-),bilateral MR[ (+)by high-quality MR[protocol.The EEG was defined as dominant IEDs if≥75%independent IEDs was confined to one temporal lobe in all EEG recordings.Clinical memory scale was administered as memory assessment of MTLE.ANOVA and non-parametric statistics were used to analyze the data in SPSS 12.0. Results The distribution of age,sex,education,occupation,living condition,course,seizure and treat among left MRI(+),right MRI(+),MRI(-),bilateral MRI(+)groups was similar.All scores in the patients with MTLE was significantly lower than normal(P＜0.05).Right MRI(+)MTLE patients had deftcits in nonsense graphics recognition(9.42±7.46)compared to left MRI(+)and MRI(-) groups((16.26±4.43)and(18.26±5.49),F=4.281,P＜0.05).Among MRI(-)patients,left IEDs,right IEDs and bilateral IEDs groups displayed not significantly different impairment in memory. Conclusion Right MRI(+)MTLE has more severe impairment in non-verbal memory,and nonsense graphics recognition can be used to detect the deficit.

Objective: To investigate the prevalence of hyponatremia and the relationship between hyponatremia and prognosis of dilated cardiomyopathy (DCM) for in-hospital patients. Methods: A total of 515 consecutive in-hospital DCM patients treated in HF center of Fu Wai Hospifal from 2008-10 to 2013-10 were retrospectively studied. Hyponatremia was deifned as the serum level of sodium < 135 mmol/L at ifrst admission. The prevalence of hyponatremia and the relationship between hyponatremia and DCM prognosis were studied including the risk of in-hospital time and mortality, the rates of all cause death and HF worsening death after discharge. Surviving patients were followed-up by clinical or telephone visit until 2014-11 or until the death. Results: There were 134/515 (26.0%) patients suffered from hyponatremia at admission, the serum level of sodium was related to HF symptom duration, NYHA functional classiifcation, systolic blood pressure (SBP), left atrial diameter and total bilirubin level, allP<0.01. Compared with non-hyponatremia, the patients with hyponatremia presented longer in-hospital time(14.8±11.1) days vs (11.2±5.8) days and higher in-hospital mortality (18.7% vs 1.8%), bothP< 0.01. There were 483 survivors discharged and were followed-up for (30.7 ± 19.5) months, during that period, the rates of all cause death and HF worsening death were 26.5% and 21.9% respectively. The patients with hyponatremia had the higher rates of all cause death (47.7% vs 20.3%) and HF worsening death (44.0% vs 15.5%), bothP<0.01. Multiple Cox regression analysis showed that with adjusted HF history (> 6 months vs≤ months ), NYHA functional classiifcation (Ⅱ-Ⅳ), SBP (per 10 mmHg elevation), total bilirubin level (per 1 mg/dl change) and LVEDD (per 5 mm change), the hyponatremia at admission is still one of the important independent predictors for all cause death (HR=1.836, 95% CI (1.248-2.702),P<0.01 and HF worsening death HR=2.139, 95% CI (1.406-3.253),P<0.01 in DCM patients after discharge. Conclusion: Hyponatremia is a common electrolyte disorder for in-hospital DCM patients, it is related to longer in-hospital time and higher mortality; higher rates of all cause death and HF worsening death after discharge in DCM patients.

Objective: To analyze the prevalence and predictor for left ventricular reverse remodeling (LVRR) in patients of primary hypertension combining left ventricular systolic dysfunction (LVSD) with tailored medication.
Methods: A total of 118 consecutive patients admitted in our unit from 2010-08 to 2012-10 with the base line left ventricular ejection fraction (LVEF)≤40%were enrolled. The demographic and clinical information with the findings of echocardiography at admission were collected. The patients were followed-up until 2013-12 or until the all cause death/cardiac transplantation. According to echocardiography, LVRR was deifned by 2 criteria at the same time:①the absolute elevation of
LVEF≥10%than base line and the follow-up LVEF≥50%,②the relative reduction of left ventricular end-diastolic diameter (LVEDD) index≥10%than base line and the follow-up LVEDD index≤27 mm/m2. LVRR prevalence with its base line predictor was investigated.
Results: The overall mean follow-up time was (23 ± 15) months, and 39/118 (33.1%) patients acquired LVRR as LVEF from the base line level (30.6 ± 6.8)%increased to the follow-up level (57.0 ± 4.9)%;LVEDD index from the base line level (31.6 ± 3.9) mm/m2 decreased to the follow-up level (24.4 ± 1.9) mm/m2, all P<0.01. The average time length for reaching LVRR was (11 ± 9) months, and 27/39 (69.2%) patients reached LVRR within 12 months. There were 79 patients not reached to LVRR, while their LVEF also from the base line level (28.6 ± 6.1)%increased to the follow-up level (39.0 ± 13.2)%;LVEDD index from the base line level (38.1 ± 5.6) mm/m2 decreased to the follow-up level (36.1 ± 6.9) mm/m2. Multivariable logistic regression analysis indicated that the patients with the shorter duration of heart failure (HF) as>6 months vs≤6 months (OR=0.244, P<0.01), shorter QRS interval as≥120ms vs<120ms (OR=0.276, P<0.05) and the higher quartile of systolic blood pressure (SBP)/LVEDD index (OR=2.724, P<0.01) at admission were the independent predictors for LVRR.
Conclusion:With tailored medication, about 1/3 of patients with hypertension combining LVSD could acquire LVRR, the patients with shorter duration of HF, shorter QRS interval and higher ratio of SBP/LVEDD index had more possibilities.
