Objective To investigate the effects of seven halothane and propofol anesthesia on heart rate and myocardial enzymes in elderly patients with coronary heart disease (CHD), and to analyze the safety of clinical application of the two kinds of anesthetic drugs.MethodsA total of 70 cases of elderly patients with coronary heart disease treatment January 2012 to December 2014 general anesthesia surgery as the research object, randomly divided into A group and B group were 35 patients in.A group were treated with seven sevoflurane anesthesia, group B patients were given propofol anesthesia, observe the change of the two groups of patients before and after anesthesia hemodynamic index and myocardial enzyme etc.index.ResultsA group of patients with HR 5min after induction and 10min were significantly lower than before the surgery, and the difference was statistically significant (P<0.05);HR stabilized after the induction of 15min and 20min, and compared with before surgery had no significant difference;patients in group B HR and 10min 5min after induction there was no obvious change compared with that before operation, no statistical significance;and after the induction of 15min and 20min HR increased, the difference was statistically significant (P<0.05).A group and B group in patients with systolic and diastolic blood pressure were lower than before anesthesia in varying degrees, and group B more significantly, the difference was statistically significant (P<0.05).A group and B group of patients after 6 h, cTnl and CK-MB in 12h and 24h than 15min before surgery has increased significantly, and A group cTnl and CK-MB were lower than B group, the difference was statistically significant (P<0.05).ConclusionThe clinical application of seven sevoflurane anesthesia for elderly patients with coronary heart disease during propofol is feasible, but seven halothane on blood pressure and heart rate of patients affected with propofol, improve the myocardial enzyme level, and better reduce the damage of perioperative myocardial, more suitable for anesthesia in elderly coronary heart disease.

Objective:To explore the effect of TSPG (total saponins of panax ginseng) on gene expression of IL-3 which is one of the important hematopoietic growth factor at early stage of hematopoiesis.Methods:Techniques of RT-PCR and in situ hybridization were used.Results:A band corresponding to IL-3 was observed after RNA extraction from TSPG stimulated Jurkat cells were subjected to RT-PCR,while such band was not observed after RNA extraction from unstimulated Jurkat cells were subjected to RT-PCR.Comparing with the control group,both quantity and intensity of IL-3mRNA expression in fetus thymocytes and splenocytes induced by TSPG were obviously promoted.Conclusion:TSPG can induce human lymphocytes to express IL-3 mRNA,thus promote human hematopoiesis at early stage.

Objective:To establish a stable and effective system of mouse embryonic fibroblasts(MEFs) feeder layer in order to separate and culture mouse embryonic stem cells(ESC) in vitro.Methods:the MEFs were isolated from the mouse embryos at 13.5~14.5dpc(days post-coitus) through primary tissue digestion and tissue piece culture.The optional planting density of cell was determined according to the cellular growth curve detected by MTT and the morphology in the culture dish under inverted microscope.The optional concentration of mitomycin C and the time treating with mitomycin on MEFs were determined by MTT assay.Murine blastcysts(3.5dpc) were cultured on the feeder layer treated by mitomycin C and ESC growth was observed.Result:The method of tissue digestion and tissue piece culture is an efficient way to obtain primary MEFs;1?105~2?105/ml cells is an optional planting density;MEFs proliferation could be effeciently repressed after being treated with mitomycin C 10?g/ml for 3.5 hours or 20?g/ml for 2.5 hours,and the quantity of MEFs could maintain at least for 7 days.ES clone could be obtained from the mouse blastcysts(3.5dpc) after being cultured on the feeder layer.Conclusion:MEFs feeder layer could effectively support mouse embryonic stem cells to grow.

Objective Panax ginseng is a well-known Chinese traditional medicine functional in “invigorating qi”,and saponins are one of its main effective fractions.Our study investigates the effect of total saponins of panax ginseng(TSPG)on human hematopoiesis at early stage and its possible regulative mechanism to clarify the hematonic mechanism of Panax ginseng. Methods The techniques of culturing hematopoietic progenitor cells in vitro,bioassay of hematopoietic growth factor(HGF),immunocytochemistry and nucleic acid in situ hybridization were used to study the effect of TSPG on IL-3’s expression in hematopoietic stromal cell and its possible mechanism. Results TSPG directly added into culture system in vitro can markedly increase the colony forming yields of CFU-Mix;the different conditioned culture media prepared with TSPG can promote the proliferation and differentiation of CFU-Mix;the protein and mRNA expression of IL-3 in BMSC and cells of EcV304,THP induced by TSPG has been much intensified.Conclusion TSPG may regulate hematopoiesis at early stage by activating IL-3's gene expression in hematopoietic stromal cell,which is the most important element in hematopietic inductive microenvironment(HIM).

The experimental teaching innovation of Histology and Embryology is summarized in this article, which turned induction, practice and examination, the three stages of experimental teaching into" Problem-Based learning", thus making the teaching effect much better.

To solve the complex interaction problems of hepatitis disease classification, we proposed a lasso method (least absolute shrinkage and selection operator method) with feature interaction. First, lasso penalized function and hierarchical convex constraint were added to the interactive model which is newly defined. Then the model was solved with the convex optimal method combining Karush-Kuhn-Tucker (KKT) condition with generalized gradient descent. Finally, the sparse solution of the main effect features and interactive features were derived, and the classification model was implemented. The experiments were performed on two liver data sets and proved that features interaction contributed to the classification of liver diseases. The experimental results showed that the feature interaction lasso method was of strong explanatory ability, and its effectiveness and efficiency were superior to those of lasso, of all pair-wise lasso, support vector machine (SVM) method, K nearest neighbor (KNN) method, linear discriminant analysis (LDA) classification method, etc.

Progressive assessment is one of the methods adopted by colleges and universities to evaluate the comprehensive quality of undergraduates.It can provide objective references for various awards and selections.Most colleges used static and transverse methods; based on these methods,advantages and disadvantages of individual undergraduates were compared with general groups,but feedback and forecast functions of assessment can not be realized.Therefore it is necessary to transform our conceptions and practice progressive assessment on comprehensive quality of undergraduates.We can learn from the relevant conceptions and methods in enterprise management and use data envelopment analysis to exclude the influence of different basic conditions of undergraduates.These undertakings are of great importance to truly reflect undergraduates' effective progress degree,guide them to test and evaluate themselves correctly and to advance comprehensive quality continuously.

Congenital cystic lung lesions are a group of congenital lung diseases with low incidence. These include congenital cystic adenomatoid malformation,bronchogenic cyst,congenital lobar emphysema and pulmonary sequestration. These malformations occur during the period of lung development stimulated by various factors. Manifestations of the diseases are very similar,but the pathogenesis and pathology are very different. Congenital cystic adenomatoid malformations are thought to be the results of the cessation of bronchiolar maturation with overgrowth of mesenchymal elements and without development of alveoli. There are 5 pathological types of congenital cystic adenomatoid malformations. Bronchogenic cysts are the results of abnormal budding from a segment of the tracheobronchial tree during embryo development,and the buds with no communication with normal tracheobronchial tree. Congenital lobar emphysema is a term reserved for hyperinflation of alveoli from idiopathic reasons or extrinsic compression,as well as pathological changes of the bronchial wall. Pulmonary sequestrations account for parts of nonfunctioning lung tissue that mostly do not communicate with normal bronchoalveolar tree and vascularized by a systemic artery,two types(intralobar and extralobar sequestration)are described.
