Vitamin E succinate (VES) has been recently recognized as a neotype tumor suppressor.However, the molecular mechanisms that VES induces apoptosis in breast cancer cells have not been validated. Current studies have indicated that VES induces breast cancer cell apoptosis through TGF-β signaling transduction pathways, Fas signaling transduction pathways, and JNK signaling transduction pathways.Other signaling transduction pathways still need to be investigated further.

Objective To explore the relationship between asymptomatic lacunar cerebral infarction and blood pressure variability (BPV) in senile patients with essential hypertension.Methods According to the results of the cranial magnetic resonance imaging (MRI),160 patients were divided into two groups:96 cases of hypertension combined with lacunar cerebral infarction group and 64 cases of simple hypertension group.Their levels and variability blood pressure were investigated by 24 hours ambulatory blood pressure monitoring.All markers included 24 h average systolic blood pressure variation (24 h SBPV),24 h average diastolic blood pressure variation (24 h DBPV),the day average systolic blood pressure variation (dSBPV),the night average systolic blood pressure variation (nSBPV),the day average diastolic blood pressure variation (dDBPV),the night average diastolic blood pressure variation (nDBPV),the standard deviation (SD)and variable coefficient (CV) of morning peak systolic blood pressure and diastolic blood pressure.Results 24 h SBPV,dSBPV,nSBPV,24 h DBPV,dDBPV,nDBPV was increased significantly in hypertension combined with lacunar cerebral infarction group compared with those in simple hypertension group (0.15±0.03 vs.0.11 ± 0.02,0.14 ± 0.02 vs.0.10 ± 0.03,0.14 ± 0.03 vs.0.10 ± 0.08,0.13 ± 0.08 vs.0.11 ±0.04,0.14 ±0.02 vs.0.11 ±0.07,0.14 ±0.05 vs.0.09 ±0.02),and there was significant difference (P ＜ 0.05).SD and CV of morning peak systolic blood pressure and diastolic blood pressure in hypertension combined with lacunar cerebral infarction group was higher than that in simple hypertension group [(15.37 ±4.55) mmHg (1 mmHg =0.133 kPa) vs.(13.53 ±2.26) mmHg,(13.64 ±4.95) mmHg vs.(9.80 ± 3.46) mmHg,0.141 ± 0.048 vs.0.113 ± 0.037,0.145 ± 0.056 vs.0.105 ± 0.036],and there was significant difference(P ＜ 0.05).Conclusion The BPV,especially morning blood pressure surge BPV are increased significantly in the hypertension combined with lacunar cerebral infarction group compared with that simple hypertension group,BPV increase is one of the important risk factors of cerebral infarction.

Objective To evaluate the accuracy of the index of consciousness (IoC) in monitoring the depth of anesthesia with sevoflurane inhalation in children,by comparing it with the bispectral index (BIS).Methods Forty-two ASA physical status Ⅰ or Ⅱ children,aged 8-12 yr,scheduled for elective abdominal surgery under general anesthesia,were studied.Anesthesia was induced with sevoflurane inhalation.The patients were endotracheally intubated.The concentration of sevoflurane was then adjusted to maintain the end-tidal concentration of sevoflurane (CETSev) at 1.6％,2.1％,2.6％,3.1％,3.6％,4.1％ and 4.6％ for5 min.The IoC and BIS values were recorded simultaneously.Results When CETSev ＜ 3.1％,CETSev was negatively correlated with IoC and BIS values,and the correlation coefficients between CETSev and IoC and BIS values were-0.927 (r1) and -0.869 (r2),respectively (P ＜ 0.01).When 3.1％ ≤ CETSev ≤ 4.6 ％,CET Sev was negatively correlated with IoC and BIS values,and the correlation coefficients between CETSev and IoC and BIS values were-0.808 (r3,P＜ 0.01) and-0.430 (r4,P ＜ 0.05),respectively.Comparison of the absolute value of correlation coefficients:there was no significant difference between r1,r2 and r3 (P ＞ 0.05) ; r1,r2 and r3 were significantly larger than r4 (P ＜ 0.01).Conclusion IoC can accurately reflect the depth of anesthesia with sevoflurane inhalation in children and when 3.1％ ≤ CET Sev ≤ 4.6 ％,the accuracy of IoC in monitoring the depth of anesthesia is superior to that of BIS.

AIM: To investigate the expression of aquaporins-1 (AQP-1)in cultured bovine corneal endothelial cells and to explore the role of AQP-1 in corneal endothelial fluid transport.METHODS:The bovine corneal cells were cultured in DMEM containing 200mL/L neonate bovine serum. AQP-1 expression in the bovine corneal endothelial cells was detected with immunohistochemistry method before and after treatment of the cells with aquaporin inhibitor, p-chloromercuribenzene sulfonate. The osmotic water permeability was determined bymonitoring volume changes of cultured bovine corneal endothelial cells.RESULTS: AQP-1 expression in the membrane of cultured bovine corneal endothelial cells was revealed by positive staining (in brown color). The reading of osmotic water permeability of the cultured bovine corneal endothelial cells before treatment with p-chloromercuribenzene sulfonate was 0.044±0.005cm/s, which significantly decreased to 0.017 0.003 cm/s(n= 15) after treatment.CONCLUSION: AQP-1 expressed in the membrane of cultured bovine corneal endothelial cells may play an important role in fluid transport of corneal endothelial cells. Alteration of the AQP-1 expression may cause abnormal corneal function and corneal edema.

Objective To observe the correlation between active vitamin D3 level and sarcopenia development in elderly patients in plateau regions and the changes in the correlation factors for sarcopenia under the invention of active vitamin D3 (Calcitriol,Cal),and to observe whether Cal could improve the muscle function.Methods 90 patients were assigned to the normal control (Con) arm,and 120 patients with sarcopenia were assigned to the sarcopenia (Sar) arm to receive different oral doses of Cal as intervention (0.25 ug/d for low dose group including 60 patients and 0.25ug bid for high dose group including 60 patients) Before and after the intervention,levels of 1,25-(OH)2D3 and the inflammatory factors TNF-α,IL-6,IL-10,and hs-CRP were detected using ELISA;HOMA-IR,BMI,and ASMI were calculated;and walking speed and grip strength were measured to observe the correlation between 1,25-(OH) 2D3 level and sarcopenia,the changes in these indicators from before to after intervention,and the efficacy and safety of oral Cal for sarcopenia.Results Prior to intervention,compared with the Con arm,1,25-(OH)2D3 level,IL-10 level,ASMI,walking speed and grip strength were significantly reduced (P＜0.01),and HOMA-IR,IL-6,TNF-α and hs-CRP were significantly elevated (P＜0.01) in both dose groups;intervention with Cal produced significant increases in 1,25-(OH)2D3 and IL-10 levels,significantly improved walking speed and grip strength (P ＜0.05),significant decreases in HOMA-IR,IL-6,TNF-α,and hs-CRP (P＜0.05),which were more marked with higher dose,but no significant changes in ASMI.From before to after intervention,there were no significant changes in BMI or hepatic/renal function,blood calcium,or blood phosphorus in either group.Conclusions The development of sarcopenia is associated with reduced 1,25-(OH)2D3 level.Cal can lower the inflammatory factors IL-6,TNF-α,and hs-CRP,and elevate IL-10,providing anti-inflammatory and immunoregulatory actions;improve muscle function and strength;and improve insulin resistance.BMI is irrelevant to the management of sarcopenia.Cal is safe at the oral dose up to 0.5 tμg/d.

Kawasaki disease, also known as infantile skin mucous membrane lymph node syndrome, is an acute vasculitis syndrome in pediatricdepartment. The lesion mainly involves medium and small arteries, particularly the coronary artery, being a major cause of pediatric coronary lesion and also a potential risk factor of coronary heart disease during later adulthood. Here the clinical data and treatment of one case of Kawasaki disease complicated with coronary aneurysm and 4 years later the occurrence of cardiocerebrovascular lesion (CCVL) were retrospectively analyzed, and the related literatures were reviewed and analyzed to approach the clinical characteristics of this disease complications. It is suggested that at early stage regular treatment should be applied and afterwards periodical follow-up should be performed; long-term monitoring coronary changes ought to be carried out to decrease the occurrence of CCVL accident.

Background Atrial fibrillation (AF) is one of the most prevalent arrthythmias. Hypertension independently accounts for more AF cases than any other risk factors. Therefore,prevention of risk factors in patients with essential hypertensives(EH) is important for early prevention and diagnosis of AF. However,only a few data are available regarding left ventricle remodeling in essential hypertensive patients with atrial fibrillation(EH+AF). Objective To study the characteristics of left heart remodeling and function and its clinical significance in EH+AF,and predict some risk factors of AF. Methods All 561 patients were recruited which included EH+AF(n=224),EH alone(n=171),AF alone(n=166) with normal subjects as control(n=157). Interventricula septal thickness at end-diastole(IVSTd),posterior left ventricular wall thickness at end-diastole(LVPWTd),left ventricular end-diastolic dimension(LVEDD),left ventricular end-systolic dimension(LVESD),left atrial dimension (LAD),left ventricular ejection fraction stroke volume(LVEF),stroke volume(SV)cardiac output(CO)were measured with echocardiography. Left ventricular mass(LVM),left ventricular mass index(LVMI)and relative wall thickness(RWT)were calculated. Results LVM,LVMI,IVSTd,LVPWTd,LVESD,LVEDD,LAD,RWT in the EH+AF group were significantly greater than those in the AF alone or EH alone patients(P
