We found previously that water soluble extract of Liriope spicata Lour (SanMaiDong) possesses cardioprotective action. The paper reported that effects of total aminoacid ex- traded from Liriope spicata Lour (Tal) on experimental myocardial ischemia in rats. The results indicate that Tal (5 mg?kg-1 ,ip) obviously antagonized ischemic ECG changes induced by pituitrin in rats. In myocardial ischemic rats caused by isoprenaline (8 mg?kg-1) Tal 15 mg? kg-1ip significantly reduced ST and decreased CPK release and lowered the content of MDA. In a myocardial ischemic mode) induced by ligat-ing the left anterior descending coronary artery in rats, Tal 15 mg?kg-1ip remarkably decreased plasma CPK and FFA levels and was found todiminish the infarct size. The ratio of its infarct size (5. 80%) is similar to that of propranolol (5. 41%),but apparently smaller than that of ligated group (18.55%). The results suggest that Tal can protect ischemic myocardium and this action may relate to the prevention of my-ocardial lipid peroxication and improvement of myocardial metabolism.

Objective To explore the effect of analgesia management on the analgesic effect and the quality of delivery of labor analgesia. Methods The 80 cases were divided into two groups according to the odd number of labor analgesia, the control group without anesthesia nurse labor analgesia, only the anesthesiologist operation, given routine obstetric care. Anesthesia nursing group for labor analgesia by anesthesiologists and nurse by anesthesia on maternal perinatal period health education and pain management, pain score was compared between the two groups (at full dilatation), mode of delivery, postpartum hemorrhage, neonatal asphyxia. Results The total score of pain in the nursing group was 3.9±0.2, while that of the control group was 8.4±0.8, and the difference was statistically significant (t=-38.5872,P=0.000); anesthesia nursing group cesarean delivery, delivery, were 1 cases, 27 cases, 12 cases; the control group were 9 cases, 21 cases, 10 cases, the difference was statistically significant (χ2=7.31, P<0.05) ; the amount of bleedingof anesthesia nursing group (175.5±42.5) ml; the control group was (226.4±52.5) ml, the difference was statistically significant (t=8.621, P<0.05); the incidence of neonatal asphyxia anesthesia nursing group 1 cases (2.5%); the control group was 3 cases (7.5%), the difference was not statistically significant (χ2=0.263, P>0.05). Conclusions During the perinatal period, the labor management and nursing intervention of the parturient women with labor analgesia are significantly reduced, the cesarean section rate is significantly reduced, and the complication rate is reduced.

Objective To investigate effect of transforming growth factor β3(TGFβ3)on expression of MMP-9,MMP-2,TIMP-1 and collagen I in rats with liver fibrosis through transduction by recombinant adeno-associated virus 2(rAAV2).Methods Rats were randomly divided into 4 groups:normal control group,model group,negative control group and TGFβ3 group.Liver fibrosis model was induced by hypodermic injection of 40% CCl4.rAAV2-TGFβ3,was injected via vena caudalis of the rats one week before CCl4 Was given.All rats were sacrificed and the liver tissues were taken 8 weeks afler injection of CCl4.The histopathological changes were observed on HE sections;the expressions of MMP-9,MMP-2,TIMP-1 and collagen I were examined by histochemistry and the positive area rates were semi-quantitatively analyzed.Results Compared with the model group and negative control group,the decreases of inflammatory infiltration and collagen fibers hyperplasia were observed in the TGFβ3 group,and the expression of MMP-9 increased(q=23.664,27.746,P<0.01),the expression of collagen I(q=5.503,5.251,P<0.01)and TIMP-1(q=5.800,8.608,P<0.01)decreased,but that of MMP-2 was not changed(q=2.1 08,0.996,P>0.05).Conclusion rAAV2-TGFβ3 can reduce the histological damage and degree of liver fibrosis in rats by inhibiting expression of TIMP-1 and collagen I,and upregulating expression of MMP-9.

Objective To investigate the influence of Cordyceps polysaceharide (Cp) on epithelial-to-mesenchymal transition (EMT) induced by transforming growth factor-β1 (TGF-β1)in proximal tubular epithelial cells (PTEC). Methods HK-2 cell proliferation was determined by MTT assay. After incubation of HK2 cells with increasing concentrations of TGF-β1 (0, 0.1, 0.5, 1, 5, 10 μg/L) at 48 h and with TGF-β1 (5 μ/L) at different time points, E-cadherin, α-SMA, FN expression at transcriptional and protein levels were detected by real-time PCR and Western blotting respectively. The cells were pretreated with 1,5, 10 g/L Cp respectively for 24 h before adding TGF-β1 (5μg/L), then the cells were incubated for additional 48 h, mRNA and proteinexpression of above 3 cytokines was examined by real-time PCR and Western blotting as well. Results CP alone (0.01, 0.1, 1,5, 10 g/L) induced HK-2 cell proliferation in a dose-dependent manner. TGF-β1 enhanced α-SMA, FN expression while inhibited E-cedherin expression at both transcriptional and" protein level in HK-2 cell. At transcriptional level, compared to single TGF-β1 (5 μg/L) stimulating group, after Cp (1,5, 10 g/L) pretreatment for 24 h, the inhibition rate of a-SMA mRNA was 37.98%, 68.08% and 84.36%, respectively; FN mRNA was 46.97%, 63.82% and 81.85%, respectively; E-cadherin was up-regulated by 0.67 fold, 2.69 folds and 5.43 folds, respectively (P＜0.05). At protein level, the inhibition rate of α-SMA was 33.40%, 47.75% and 68.50%, respectively; FN was 16.26%, 65.92% and 80.30%, respectively; E-cadherin was up-regulated by 1.33 folds, 3.19 folds and 4.29 folds, respectively (all P＜0.05). Under Light microscopy, the Cp reversed cell shape from spindle-shape induced by TGF-β1 to nearly normal shape. Conclusion Cp may exert its inhibitive effects on TGF-β1-induced EMT.

Objective To investigate the influence of albumin on the expression of angiotensin-eonverting enzyme (ACE) in cultured human proximal tubular ceils (HK-2). Methods HK-2 cells were exposed to 2.5, 5, 10 g/L bovine serum albumin (BSA) for 6 h and 12 h respectively. The expression of ACE in HK-2 cells was detected by real-time RT-PCR and Western blot. Results Compared to the control group, the expression of HK-2 cells ACE mRNA treated for 12 h with different concentrations of BSA (2.5, 5, 10 g/L) significantly increased (P

Nutritional studies were made on eleven elderly male hospitalized patients (60-83 years old) receiving nasogastric feeding for from several months to as long as 10 years duration.The major nutrients intake obtained was listed in table 1. According to the physical examination, biochemical parameter of the blood and nitrogen balance, the average intake 1722 kcal of enegy (1175-2700 kcal) and 82.4 g of protein (52.6-117.3g) probably met the need of the patients. Vitamin status (B1 B2 C) by blood and urine examination was rather good because of taking additional vitamin preparation regularly daily besides meal sources. Blood cholesterol concentration was moderately higher (339.3mg/dl) than the normal value possibly due to excessive daily intake. It suggested that the intake of cholesterol should be restricted.A better nasogastric feeding regimen was presented and discussed.

Objective To investigate whether low density lipoprotein receptor (LDLr) pathway involves in the progression of vascular calcification (VC) in hemodialysis patients under microinflammation.Methods Twenty-eight hemodialysis patients were divided into control and inflammation group according to plasma C-reactive protein level.Surgically removed tissues from radial artery of patients receiving arteriovenostomy were used in experiments.Foam cell formation and calcification deposition were observed by hematoxylin-eosin (HE) and alizarin red S staining respectively.VC-related protein expression,such as bone morphogenetic proteins-2 (BMP-2),collagen Ⅰ,alkaline phosphatase (ALP),and LDLr and its related nuclear factor of transcriptional regulation,such as sterol regulatory element binding protein-2 (SREBP-2) and SREBP cleavage-activating protein (SCAP),were detected by immunohistochemistry and immunofluorescence staining.Results HE and alizarin red S staining showed that there were parallel increased foam cell formation and calcium deposit in continuous cross-sections of radial arteries in inflammation group compared to control group,which were closely correlated with increased protein expressions of LDLr,SREBP-2,BMP-2,and collagen Ⅰ as shown by immunohistochemical and immunofluorescent staining.Confocal microscopy confirmed that inflammation enhanced the translocation of SCAP/SREBP-2 complex from endoplasmic reticulum to Golgi,thereby activating LDLr gene transcription.Inflammation increased protein expression of ALP and reduced protein expression of alpha-smooth muscle actin,contributing to the phenotype conversion of vascular smooth muscle cells in calcified vessels from the fibroblastic to the osteogenic,which were the main cell components in VC.Further analysis showed that the disruption of LDLr pathway induced by inflammation was positively correlated with the enhanced expression of BMP-2 and collagen Ⅰ (r=0.782,P＜0.01; r=0.644,P＜0.05).Conclusion Inflammation accelerates the progression of VC in hemodialysis patients through the disruption of LDLr feedback regulation.

Objective: To summarize the characteristics of arrhythmia with the relevant factors affecting its prognosis in patients of apical hypertrophic cardiomyopathy (AHCM). Methods: A total 283 AHCM patients with echocardiography or cardiac magnetic resonance (CMR) conifrmed diagnosis in our hospital from 2005-01 to 2012-08 were summarized. The patients were divided into 2 groups: With arrhythmia group, n=103 and Without arrhythmia group,n=180. The endpoint event was followed-up by clinical and telephone visits in both groups and the relevant risk factors affecting AHCM prognosis were investigated by Cox regression analysis. Results: There were 269 patients ifnished the follow-up investigation, 98 in With arrhythmia group, 171 in Without arrhythmia group, and the death rate was 4.08% vs 1.17%, the occurrence of endpoint event was 18.37% vs 5.58%respectively. Cox regression analysis indicated that age (HR=23.051, 95% CI 1.08-1.068,P<0.005), left atrial diameter (HR=4.113, 95%CI 1.002-1.119,P=0.043) and NT-proBNP (HR= 18.653, 95% CI 3.433-26.650,P<0.005) were the independent risk factors affecting prognosis in AHCM patients. Conclusion: Arrhythmia is one of the common presentations of AHCM, it does not have much impact on survival, while it may cause ventricular ifbrillation and increase the occurrence of cardiovascular events.

Objective:To investigate the expression and prognostic significance of CD19 in patients with Acute myelogenous leukemia with AML1-ETO positive. Methods: Clinical data of 66 patients AML with AML1-ETO positive who were newly diagnosed from Jan 2010 to Dec 2015 were collected. To retrospectively analyze the relationship between clinical characteristics and expression of CD19,so dose the prognosis. Results:The positive rate of CD19 expressing in AML with AML1-ETO positive was 50. 0%. There were no statistically significant differences in terms of age,gender,hemoglobin,platelet,percentage of bone marrow blasts,accompanied with chromosome ,gene mutations between patients with and without CD19 expression(P>0. 05). The white blood cell count(WBC) of the CD19 negative group was higher than CD19 positive group,while showed significant difference(P=0. 027). Although the relapse-free survival (RFS) of patients with CD19 expression was higher than those without,no significant difference was calculated (P=0. 105). Patients with CD19 expression had superior overall survival ( OS ) compared to those without CD19 expression ( P = 0. 030 ) . Multivariable analysis for OS identified CD19 positivity as an independent predictor associated with better prognosis. Conclusion: The expression of CD19 in AML with AML1-ETO positive may be an indicator associated with better prognosis.
