With the rapid development of internet and multimedia technology,the training of visual literacy has gained much more attention.In the teaching of Biochemistry,when confronting numerous visual tools in various ways for biological molecules research and rapid development of subject,teachers and students are required to have higher level of visual literacy.However,it is slighting and retarded to develop visual literacy education in China.Therefore,it is very important to emphasize the improvement of visual literacy in the teaching of Biochemistry,which can improve the ability in teaching design and learning method in this era of graphical interpretation.

Objective:To investigate the neuro psychological characteristics and their change in leukoaraiosis(LA).M ethods:29 asymotamatic LA sub jects and 25 normal controls were compared on a comprehensive neuropsychological test battery,which included Revised Visual Retention Test(VRT),Wechsler Adult I n telligence Scale-Revised in China(WAIS-RC),and Zung's Self-rated Depression Scal e (SDS).Both groups were matched for sex,age and education.Results:The LA group s cored lower on the VRT than did the control group ,and the mean standard score o f the Memory and/or Freedom From Distractibility factor(MFSs)of the WAIS-RC in t he LA group was lower than that of the control group.There were no significant d ifferences o f the Full Scale IQ of the WAIS-RC and the score of the SDS between the two grou ps. Conclusion:LA may contribute to cogniti ve impairment in the neurologically healthy elderly,especially involving deficits of visuospatial ability ,disfunct ion of memory and attention,as well as slowing of mental processing.

Objective: To investigate the effect of miR-144-3p modulating proliferation, migration and apoptosis of liver cancer Huh-7 cells through blocking frizzled class receptor 4 (FZD4)/Wnt/β-catenin pathway and the possible mechanism. Methods: A total of 18 pairs of cancer tissues and corresponding para-cancerous tissues from liver cancer patients, who underwent surgery in Workers' Hospital of Liuzhou City from March 2012 to July 2017, were collected for this study; in addition, hepatic cancer cell lines (Huh-7, SMMC7721 and MHCC97) and human normal liver epithelial cell line THLE-3 were also collected. The expression of miR-144-3p in liver cancer tissues and cell lines was detected by qPCR. MiR-144-3p mimics/inhibitor and FZD4 siRNA were transfected into liver cancer Huh-7 cells; the proliferation, migration and apoptosis of Huh-7 cells were evaluated by CCK-8 assay, Transwell assay, wound healing assay and Annexin V-FITC/PI double staining flow cytometry assay, respectively. The interaction between miR-144-3p and FZD4 was verified by dual-luciferase reporter gene assay. Results: The expression of miR-144-3p was down-regulated in liver cancer tissues and cell lines (P<0.05 or P<0.01). Over-expression of miR-144-3p significantly inhibited cell proliferation viability, migration but induced apoptosis of Huh-7 cells (all P<0.01). Moreover, dual-luciferase reporter gene assay showed that miR-144-3p directly interacted with FZD4 and suppressed its expression. Furthermore, in vitro experiments verified that miR-144-3p targeted FZD4 to suppress the proliferation, migration and promote apoptosis of Huh-7 cells via blocking Wnt/β-catenin pathway (all P<0.01). Conclusion: miR-144-3p inhibits malignant biological behaviors of liver cancer Huh-7 cells via blocking Wnt/FZD4/β-catenin signaling pathway, which may provide potential molecular targets for early diagnosis or treatment of liver cancer.

Objective To investigate the unusual CT features of pulmonary sclerosing hemangioma (SH). Methods Clinical and CT features of 25 patients of pulmonary SH proved with pathology were reviewed, among which 15 patients underwent plain and enhanced CT scan, 10 underwent only plain CT scan. Results Solitary nodules (20/25, 80.00%) and solitary mass (5/25, 20.00%) were found with CT. CT features included slight lobulation (6/25, 24.00%), calcification (6/25, 24.00%), ground glass opacity (2/25, 8.00%), emphysema (1/25, 4.00%), endobrochial variant (1/25, 4.00%), short speculation (1/25, 4.00%) and vascular bundle (2/25, 8.00%). Slight or remarkable enhancement was noticed in all 15 patients underwent contrast enhanced CT. Conclusion CT can reveal features and unusual manifestations of pulmonary SH, and is helpful to the diagnosis of pulmonary SH.

Objective To detect the apoptosis and the intensity of proliferation in different types of renal pathology in children with lupus nephritis (LN), analyzed the relationship between apoptosis and proliferation in LN. Methods Twenty - seven children (aged 7-16 years old, 21 type IV and 6 type V ) with biopsy- proven LN and nine as controls were included in the study. Apoptosis was detected by in situ nick- end labeling techniques (TUNEL) in renal biopsy samples. Immunohistochemistry was employed to detect the proliferating cells identified by proliferating cell nuclear antigen (PCNA) and detect the expressions of proteins of apoptosis associated gene PDCD5 and Caspase - 3 in these patients. Results 1. Compared to type V LN, the patients with type IV LN had more apoptolic cells,more PCNA positive cells and higher ratios of PCNA/apoptosis (P/A) in glomeruli. 2. There were no difference in expression of PDCD5 in glomeruli in type IV LN compared with those in type V LN. Numbers of apoptotic cells were observed in glomeruli. The expression of Caspase- 3 in type IV LN increased in glomeruli compared with that in type V LN. Conclusions The up- regulation of mechanism of apoptosis in type IV LN was less than that of type V LN. Caspase- 3 participated in the apoptosis of glomeruli of LN, but PDCD5 did not play a role during apoptosis of glomeruli of LN or the effect of PDCD5 promoting apoptosis was depressed.

In this article a new principle of geometric design for blade's surface of an impeller is provided. This is an optimal control problem for the boundary geometric shape of flow and the control variable is the surface of the blade. We give a minimal functional depending on the geometry of the blade's surface and such that the flow's loss achieves minimum. The existence of the solution of the optimal control problem is proved and the Euler-Lagrange equations for the surface of the blade are derived. In addition, under a new curvilinear coordinate system, the flow domain between the two blades becomes a fixed hexahedron, and the surface as a mapping from a bounded domain in R2 into R3, is explicitly appearing in the objective functional. The Navier-Stokes equations, which include the mapping in their coefficients, can be computed by using operator splitting algorithm. Furthermore, derivatives of the solution of Navier-Stokes equations with respect to the mapping satisfy linearized Navier-Stokes equations which can be solved by using operator splitting algorithms too. Hence, a conjugate gradient method can be used to solve the optimal control problem.

Methods 80 patients with chronic obstructive pulmonary disease in stable period from June 2014-2016 year in May in our hospital were randomly divided into control group and experimental group, 40 cases in each group. The control group of patients with the use of simple Symbicort treatment and routine nursing care to patients, patients in the experimental group using Symbicort combined with Bailing Capsule for treatment, and the implementation of targeted nursing intervention measures, compare the effect of two groups of patients and nursing satisfaction. Results the clinical treatment of patients in the experimental group the total efficiency 95.0%, nursing satisfaction was 97.5%, the control of clinical patients in the treatment group the total effective rate was 80.0%, nursing satisfaction was 87.5%, the experimental group was significantly higher than the control group, the difference was statistically significant (P<0.05). Conclusion Chronic In the stable period of obstructive pulmonary disease, the combination of Xin Yi capsule combined with Bailing capsule can effectively improve the pulmonary function of patients and improve the clinical therapeutic effect, and is worthy of popularization and application in clinic.
