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 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 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 analyze the requirement of pharmaceutical care among physicians, nurses and patients and to explore work mode of clinical pharmacists. METHODS: The requirement of pharmaceutical care in concrete cases was summarized by combining with experience of author as clinical pharmacist in cardiology department. RESULTS: The advantage of clinical pharmacist and convenient consultation for selection of drugs contribute to complementary with physicians’ work. CONCLUSION: Clinical pharmacist provides various pharmaceutical care according to the requirement of doctors, nurses and patients.

Objective To investigate whether unfolded protein response (UPR) plays a role in the pathogenesis of spondyloarthritis (SpA),and to assess UPR-related gene expression in SpA and other arthritis patients.Methods Eighteen patients with SpA,12 with rheumatoid arthritis (RA) and 6 with osteoarthritis (OA) were recruited.Macrophages were isolated from synovial fluid samples by immunomagnetic separation.The expression of UPR-regulated genes,including binding immunoglobulin protein (BiP),glucose-regulated protein 94 (GRP94),C/EBP homologous protein (CHOP),growth arrested and DNA damage-inducible 34 (GADD34),X-box binding protein 1 (XBP-1) and endoplasmic reticulum DnaJ homolog 4 (ERdj4),was tested by real time polymerase chain reaction (PCR).Results Compared with macrophages in OA patients,the expression of BiP and GRP94 mRNA [(6.06 ± 2.08) × 10-2 vs (1.11 ±0.72) × 10-2 for BiP mRNA,11.80(7.30-38.40) × 10-3 vs 1.27(1.02-4.18) × 10-3 for GRP94 mRNA,both P values ＜0.01] was significantly increased in macrophages in SpA patients.XBP1 mRNA was up-regulated [(12.70 ± 5.20) × 10-3 vs (4.14 ± 2.56) × 10-3,p ＜ 0.01] in SpA group as well.UPR-regulated gene expression in SpA patients with HLA-B27 positive or HLA-B27 negative was similar.However,none of UPR-regulated genes showed different expression between the SpA group and RA group except for GADD34 mRNA [7.30 (5.56-15.40) × 10-3 vs 21.30 (12.20-27.60) × 10-3,P =0.009].Conclusions Our data suggest that UPR possibly participates in the pathogenesis of SpA,although the relationship between HLA-B27 and UPR still needs further investigation.

Conclusion Emergency early mechanical ventilation and bronchoalveolar lavage and drug intervention to severe asthma had better clinical efficacy ,which can significantly improve the clinical symptoms of the patient .

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.
