Objective:To investigate the effect of miR-154 on the apoptosis of hepatic stellate cells (HSC-T6). Methods:Hepat-ic stellate cells (HSC-T6) were transfected with miR-154 mimics and miR-154 inhibitor, and the cells were trandfected with mimics NC and inhibitor NC as the negative control. The effects of miR-154 on the proliferation of HSC-T6 were detected at different time points by CCK-8. A flow cytometry with double staining of Annexin and PI was used to detect the cell cycle and apoptosis rate of HSC-T6. Results:The proliferation ability of the cells was increased,the apoptosis rate was decreased significantly, and the proportion of cells in G0/G1 phase were decreased, and those in G2/M phase were increased significantly after transfected with miR-154 mimics. The proliferation ability of the cells was decreased,the apoptosis rate was increased significantly, and the proportion of cells in G0/G1 phase were increased, and those in G2/M phase were decreased significantly after transfected with miR-154 inhibitor. Conclusion:MiR-154 can promote the proliferation of HSC-T6 and inhibit the apoptosis of HSC-T6.

Objective:To summarize the single nucleotide polymorphisms ( SNPs) in ABCC2 and the effect on clinical drug appli-cation. Methods:According to the related articles published in domestic and abroad, the correlation between the single nucleotide pol-ymorphisms in ABCC2 and drug responses was classified and summarized. Results:ABCC2 translocator played an important role in the transmembrane transport of many physiological compounds and exogenous compounds. Numerous studies have demonstrated that the single nucleotide polymorphisms in ABCC2 possibly affected the expression or activity of ABCC2, which leading to the variation in the absorption, distribution and excretion of certain drugs and toxicants. However, the limitation and controversy were still emerged in the results. Conclusion:The influence of ABCC2 single nucleotide polymorphisms on clinical drug application shows significantly referen-tial value for the guidance of medication and the evaluation of efficacy, however, it can not be used as the only indicator yet.

Objective To study the expression of apolipoprotein H (ApoH) in childhood primary nephrotic syndrome (PNS) and to discuss its role in PNS. Methods Immunohistochemistry staining and real-time quantitative polymerase chain reaction(RT-PCR) were performed to evaluate the expression of ApoH in renal tissues of 78 patients with PNS and 14 cases of normal controls. Serum albumin, serum lipid, proteinuria and urinary retinol binding protein (RBP) were tested before renal biopsy in all patients. Tubulointerstitial lesions were investigated. Results (l)There was positive expression of ApoH in renal tissues of PNS patients and normal controls,mainly in the proximal tubules by immunohistochemistry staining. ApoH mRNA was also shown in all renal tissues by RT-PCR. ApoH protein expression was positively correlaed with its mRNA expression(r=0.264, P 0.05) whereas these data displayed no significant difference between two groups. Above expression in mesangial proliferative glomerulonephritis (MsPGN) and focal segmental glomersclerosis (FSGS) down-regulated significantly (3.30?0.28,2.82?0.36, and 10.13?3.09,10.12?1.02, respectively), as compared to those in MCNS,MN and the controls, P

Objective: To investigate the effect of dimethyl dicarboxylate biphenyl ( DDB) on the proliferation, apoptosis and PPARγ expression of hepatic stellate cells. Methods: HSC-T6 cells were cultured in 96-well plates and 6-well plates, and after the 24-hour drug treatment, the influence of DDB on the proliferation and apoptosis of HSC-T6 were detected respectively by CCK-8 kit and flow cytometry. Quantitative real-time-PCR ( Q-PCR) and Western blotting were adopted to determine the effect of DDB on the PPARγmRNA level and the protein expression in HSC-T6 cells. Results:DDB obviously inhibited the proliferation of HSC-T6 (P<0. 05) and significantly promoted the apoptosis of HSC-T6 (P<0. 05) at the experimental concentration (8-64 μmol·L-1) when compared with the control group (0 μmol·L-1). The expression of PPARγ in drug-treated HSC-T6 was notably improved. Conclusion: DDB can inhibit the proliferation and promote the apoptosis of HSC-T6 cells by up-regulating the expression of PPARγ.

Objective To investigate the expression of human epidermal growth factor receptor?2(HER?2)and Survivin protein in gastric cancer tissue,and explore its relationship with clinicopathological characteristics. Methods Immunohistochemistry assay was used for detection of HER?2 and Survivin protein expression in 70 gastric cancer biopsy samples. The relationship with the clinicoathological parameters in patients with gas?tric cancer was analyzed. Results The expression of HER?2 and Survivin protein was correlated with tumor differentiation ,TNM stage and lymph node metastasis(all P<0.05),but not with sex,age,the diameter of tumor. The correlation analysis of positive rate and the semi?quantitative pro?tein expression showed that the expression of Survivin and HER?2 was significantly positively related(all P<0.01). Conclusion The positive ex?pression of HER?2 and Survivin protein in gastric cancer correlates with tumor differentiation ,TNM stage and lymph node metastasis. HER?2 ex?pression significantly correlates with Survivin at the protein level in gastric cancer tissues.

Objective To evaluate the effectiveness of discharge planning in patients after total laryngectomy. Methods One hundred and four patients were randomly divided into the intervention group and the control group, there were 52 cases in each group. The patients in the control group were received routine nursing, while the patients in the intervention group were received discharge planning based on routine nursing. The patients'days of hospitalization, scores of the Exercise of Self-care Agency Scale (ESCA) at discharge and 4 weeks after discharge, scores of University of Washington Quality of Life Questionnaire (UW-QOL) at 4 weeks after discharge and re-admission rate were compared between the two groups. Results The ESCA scores in the intervention group at discharge (108.62 ± 11.23) and 4 weeks after discharge (116.35 ± 12.08) were significantly higher than those of the control group at discharge (96.16±10.34) and 4 weeks after discharge (105.20±10.76) respectively (t=5.886, 4.970, P<0.05), and the UW-QOL score in the intervention group (810.56±98.25) was significantly higher than that of the control group (687.32±96.74) at 4 weeks after discharge (t=6.445, P<0.05). No significant difference in the days of hospitalization was found between the intervention group (15.27 ± 3.33) and the control group (16.60 ± 3.97) (P>0.05). The re-admission rate in the intervention group (2/52,3.85%) was significantly lower than that of the control group (8/52,15.38%) (χ2=3.983, P<0.05). Conclusions Discharge planning can improve the ability of self-care and quality of life in patients after total laryngectomy, and reduce the re-admission to hospital.

Objective:To explore the effect of P-glycoprotein ( P-gp) activity on its mediated imatinib mesylate accumulation and intracellular drug membrane permeability. Methods: 1199G/wt ABCB1 and 1199A/mut recombinant plasmids were transferred into HEK293 cells, respectively, and the expression levels of mRNA in different cell models were investigated by RT-PCR. Cell Counting Kit-8(CCK-8) assay was used to detect the drug toxicity in different cell models, HPLC was applied to determine the drug concentra-tion in different cell models and evaluate the intracellular accumulation, and transmembrane resistance experiment was employed to de-tect the transmembrane permeability and evaluate the effect of P-gp activity on drug transportation. Results: Cytotoxicity test showed that the drug concentration in the transferred cells was lower than that in the control group, which proved that P-gp had the function of mediating drug out of cells. HPLC and transepithelial electrical resistance experiment showed that compared with the wild type of AB-CB1 (1199G) cells, mutation of ABCB1 1199A cells had stronger effect on P-gp mediated mesylate imatinib accumulation and drug membrane permeability. Conclusion:The experiment manifested that ABCB1 (1199G/A) site mutation can change the coding protein P-gp activity and the polymorphisms will lead to the increase of mesylate imatinib clearance rate and the decrease of effective drug con-centration in target cells. Meanwhile, the clarification of ABCB1 genetic types in clinics can guide the individualized medication of imatinib mesylate.
