ObjectiveTo evaluate regional myocardial systolic function in patients with hypertrophic cardiomyopathy(HCM) by strain and strain rate imaging.Methods38 patients with HCM(observe group) and 36 healthy volunteers(control group) were involved in this study.All subjects were received conventional 2D-Color Doppler echocardiography and Color Doppler myocardial image(CDMI) ,then analyzed the regional myocardial function by strain and strain rate imaging.ResultsComparwed with the control group, left atrial diameters (LAD), left ventricular diameters (LVD), left ventricular end-systolic dimension (LVDs), interventricular ventricular septal (IVS) and left ventricular posterior wall(LVPW) were significantly increased in patients of observe group (all P < 0.05), but left ventricular ejection fraction(LVEF) was decreased(P <0.05).Patients with HCM showed regional longitudinal peak systolic myocardial deformation properties lower than those of counterparts at inferior, lateral, posterior, frontal and septum waLl of left ventricular(all P < 0.05).ConclusionHypertrophic cardiomyopathy was associated with significant reduction in systolic function of left ventricle and strain and strain rote imaging was useful in evaluating the change.

The effects of Amrinone (AMR)on left ventricular function in 30 cases of congestive heart failure patients was assessed by M-mode and pulsed Doppler echocardiography. AMR improves the systolic and diastolic function of left ventricle during and after 10 min (AMR lmg ? kg-1, infusion ). The mean stroke volume increased 20% and 18% ; cardiac output increased 23% , 19% ; cardiac index increased 23% and 23% ; ejection fraction increased 32% , 30%; mVcf increased 50% and 48% ; filling velocity in early diastole increased 30% and 21 %; respectively. There were no significant differently between during and after AMR infusion, but there were signifcantly difference a-mong before, during and after AMR infusion. The heart rate changed slightly without statistic significance. The results suggest that AMR could improve the systolic and diastolic function of left ventricle in congestive heart failure patients.

AIM: To discover specific neural stem cell (NSC) proliferation-promoting factor, which will contribute to study on development of nervous system and treatment of nervous system diseases. METHODS: The extracts of forebrain, midbrain,afterbrain and cerebellum of neonatal mice were prepared, and the NSCs of newborn mice were cultured in vitro. Neurospheres were observed, immunocytochemical staining of characteristic protein, nestin, and MTT assay were performed to identify NSCs and their proliferative properties. RESULTS: A great deal of neurospheres were formed in the presence of the extracts of afterbrain and cerebellum, which were positive for characteristic protein (Nestin) of NSC showed by immunocytochemical staining. CONCLUSION: The afterbrain and cerebellum extracts can increase the total number of NSCs isolated from newborn mice in vitro in a dose-dependent manner.

OBJECTIVE To explore the safe and effective dose of sirolimus (Rapamycin,Sir) and its effect on seizure comorbidities. METHODS Immature C57BL/6 mice at postnatal 10 d of age were administered with kainic acid(KA) 12.0 mg · kg-1 intraperitoneally by a single injection to induce acute seizure. Sir 0.3, 1.0 and 3.0 mg · kg-1 was injected 24 h after seizure every other day until 3 d, 1 week, 3 weeks, 5 weeks and 6 weeks. Western blotting analysis was used to detect the expression and phos?phorylation level of S6 protein and to determine the minimum effective dose of Sir. Effect of the mini?mum effective dose of Sir on cognitive function and body growth was observed by several evaluations. Immunofluorescent intensity of Doublecortin (DCX) immunofluorescent staining was conducted to evaluate the development of neurons in the hippocampus. Morris water maze was used to assess the cognitive function. Tail suspension test, O maze and new object recognition test were used to study the anxiety-like behaviors of mice. RESULTS The result of Western blotting showed that Sir 0.3 mg · kg-1 had no significant effect on the phosphorylation of S6 protein in normal mice or KA mice, whereas 1.0 and 3.0 mg · kg- 1 could significantly inhibit the phosphorylation of S6 protein in KA mice (P<0.05). Sir 1.0 mg·kg-1 had no obvious effect on DCX-positive cells or body wass. Morris water maze showed that KA-induced seizure resulted in prolonged escape latency and swimming length (P<0.05), and a decreased crossing number of target quadrant (P<0.05). Sir 1.0 mg·kg-1 significantly reversed the deficit of cognitive function of KA-induced seizure mice (P<0.05), whereas no significant difference was found between Sir group and normal control group. Compared with normal control group, model group showed increased freezing time in tail suspension test (P<0.05), decreased migration length and reten?tion time in open arms in O maze (P<0.05), decreased retention time and touch frequency with new objects, migration length and average speed in new object recognition test (P<0.05). Sir 1.0 mg · kg-1 significantly reversed the above anxiety and depression status, whereas no significant difference was found between sirolimus group and normal control group. CONCLUSION Sir 1.0 mg · kg-1 inhibits the abnormal activation of mTOR pathway and the formation of epilepsy comorbidity in immature mice. Along with its mild side effect in development, Sir 1.0 mg · kg-1 will be an ideal dose to be used in the treatment of seizure in immature mice.

Background and purpose:Hepatocellular carcinoma (HCC) is one of the most common malignant tumors. Intrahepatic recurrence is the main factor affecting its medium-term survival rate. Therefore, the search for the markers of metastasis is essential. This study aimed to evaluate the relationship of expression of tyrosine kinase phosphorylation Tyr416 of sarcoma (SRC pY416) in HCC with clinical parameters and prognosis. Methods:Immunohistochemical method and Western blot were used to detect the expression of non-receptor tyrosine kinase (SRC pY416) in 112 cases of HCC tissues and 40 cases of corresponding cancer adjacent normal liver tissues. Hepatitis B virus (HBV) DNA and alpha fetoprotein (AFP) in patients were detected with chemiluminescence. In the 12 months Follow-up of the study,the association between SRC pY416 expression and clinical parameters was analyzed. Results:SRC pY416 expressions in HCC (65.40±15.69) were higher than those in cancer adjacent normal liver tissues (11.25±2.73,P<0.001). The expressions of SRC pY416 were all associated with the age, the liver cirrhosis, the complete capsule, the tumor differentiation, the HBV DNA and the AFP value of the patients (P<0.01). 12 months after operation, single factor analysis showed that the recurrence was associated with the tumor differentiation, the HBV DNA, the AFP value and the expression of SRC pY416 of the patient (P<0.01). Multivariate analysis showed that the expression of SRC pY416 was an independent prognostic factor for recurrence and metastasis in patients with HCC in 12 months. Conclusion:SRC pY416 may play an important role in the metastasis of HCC. The expression of SRC pY416 may be the marker for HCC liver metastasis.
