OBJECTIVETo explore the differentially expressed genes and related signaling pathways in MC3T3-E1 osteo- blasts in response to suitable fluid shear stress values and action time with cDNA microarrays.

METHODSMC3T3-E1 cells cultured on a cover slip were subjected to fluid shear stress using a parallel plate flow chamber. The harvested RNA was used for microarray hybridization comprising approximately 44 170 genes, as well as for the subsequent real-time quantitative polymerase chain reaction validation of expression levels for selected genes. Microarray results were analyzed by using both GO and Pathway analysis.

RESULTSMicroarray analysis indicated that 884 differentially expressed genes were found. Among these genes, 444 were upregulated, whereas 440 were downregulated. The Notch signal and RIG- I -like receptor signaling pathways were involved in the Pathway analysis. GO analysis mainly involved different functional classifications, such as prostaglandin biosynthesis, nitric oxide-mediated signal transduction, calcium mediated signal, and cellular immune response, among others.

CONCLUSIONThe mechanism underlying the protective effect of fluid shear stress on MC3T3-E1 cells might be related to promoting cell survival- and inhibiting cell apoptosis-related signaling pathways and biological processes.

Objective: To evaluate the intervention effect of clinical pharmacists in hypertension chronic disease management. Methods:All the patients with hypertensive chronic diseases from Ziyang community, Xingan Street, Beilun district were involved in the study. Combined with community doctors, clinical pharmacists provided pharmaceutical care for the patients, such as regular face-to-face medication guide, telephone communication, home follow-up, special lectures on health and so on. The cognitive level, blood pressure control level and medication compliance were statistically analyzed and compared before and after the pharmacy intervention. Results:After the intervention of clinical pharmacists, the level of hypertension cognition and the level of antihypertensive drug under-standingof the patients was improved significantly (P<0. 05 or 0. 01), the level of blood pressure control and medication compliance of the patients were improved significantly (P<0. 01), and unscheduled outpatient rate, emergency rate, hospitalization rate and fre-quency were decreased (P<0. 05 or 0. 01).

OBJECTIVETo investigate the role of N-cadherin and fibronectin during chondrogenesis.

METHODSImmunohistochemical method and autibody induced changes of aggregation of cells were used to assay the expressions of N-cadherin and fibronectin during cell differentiation.

RESULTSThe N-cadherin was present in the area of the cell nodular area in the 24 hours group after adding chondrogenic revulsant, then there was a down-regulating trend. Fibronectin was expressed in 48 and 72 hours groups after adding chondrogenic revulsant, and showed to be negative afterward. The antibody against fibronectin or N-cadherin could inhibit the formation of cellular nodule markedly.

CONCLUSIONSCell adhesion factors play an important role during cell differentiation. TGF-beta(1) stimulates chondrogenesis via transition from an initial N-cadherin-contributing stage to a succedent fibronectin-contributing stage during the process of chondrogenesis in MSCs. Further study is needed to evaluate whether or not it can promote chondrogenesis by transfecting cDNA of CAMs to MSCs.

ObjectiveTo investigate the association of KCNJ11 rs5210 single nucleotide polymorphism with nonalcoholic fatty liver disease (NAFLD) and coronary artery disease (CAD) in the Chinese Han population in Qingdao, China. MethodsA total of 246 patients with NAFLD who attended Qingdao Municipal Hospital from December 2018 to September 2019 were enrolled as NAFLD group, 201 patients with CAD were enrolled as CAD group, and 116 patients with NAFLD and CAD were enrolled as NAFLD+CAD group; 342 healthy individuals were enrolled as control group. Fasting venous blood samples were collected for biochemical analysis. Whole blood genomic DNA was extracted, and PCR was used to determine KCNJ11 rs5210 genotype. The chi-square test was used to analyze whether the distribution of KCNJ11 rs5210 gene frequencies met the Hardy-Weinberg equilibrium, in order to determine whether the tested samples could represent the population. The chi-square test was used to analyze the differences in sex and genotype/allele frequency between groups. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups; the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups, and the Bonferroni method was used for further comparison between two groups. The unconditional logistic regression model was used to calculate odds ratio (OR) and 95% confidence interval. ResultsThree genotypes (AA, GA, and GG) of KCNJ11 rs5210 were found by gene sequencing. There were no significant differences in rs5210 allele frequency and genotype distribution between the control group, the NAFLD group, the CAD group, and the NAFLD+CAD group (all P＞0.05), and there were still no significant differences after adjustment for sex, age, and body mass index (BMI) (all P＞0.05). For all subjects, the subjects with AA genotype had a higher level of alkaline phosphatase than those with GA genotype (P=0.048); in the NAFLD group, the patients with GA genotype had significantly higher BMI and total bilirubin than those with AA genotype (P=0.042 and 0.002). The unconditional logistic regression analysis showed that elevated BMI was associated with the risk of NAFLD (OR=1.35, P＜0.01), while decreased high-density lipoprotein (HDL) might indicate an increase in the risk of NAFLD (OR=0.33, P＜0.01); elevated fasting plasma glucose and decreased HDL might indicate an increase in the risk of CAD (OR=1.51 and 0.11, both P＜0.01) and NAFLD with CAD (OR=1.46 and 0.06, both P＜0.01). ConclusionThere is no significant association between KCNJ11 rs5210 polymorphism and the risk of NAFLD and CAD in the Chinese Han population in Qingdao.
