AIM:Targeting of focal adhesion kinase (FAK) gene,we aim to construct FAK shRNA lentiviral vector and to identify its function on the growth of leukemic cells.METHODS:FAK shRNA was chemically synthesized,and inserted into a GFP-lentiviral plasmid through molecular biology methods.After packaged and concentrated,the lentiviral-FAK-shRNA-vector was transduced into a human leukemic cell line.FAK gene expression was detected by reverse transcriptional PCR and Western blotting.Cell apoptosis was measured by Annexin V labeling.RESULTS:The results showed that FAK shRNA was successfully inserted into the lentival vector,and the infection efficiency varied from 10% to 25%.Compared to the control vector (lentival vector without FAK shRNA),FAK shRNA inhibited the expression of FAK mRNA and protein by 40% and 70%,respectively.Moreover,the results of apoptosis experiment showed that the percentages of Annexin V+ cells in control vector group and FAK shRNA group were (4.19 ? 0.36) % and (8.48 ? 0.58) % respectively,the difference was statistically significant (P

OBJECTIVETo investigate the role of multidrug resistance-associated protein 2 (MRP2) in the hepatic cell membrane of rats.

METHODSThirty healthy Wistar rats were divided randomly into six groups based on time of administration (2 w, 4 w, 6 w) of 20 mg/kg of sodium arsenite, and their corresponding control groups. Animals were administered every other day. Arsenic content in blood and bile were detected by atomic absorption spectroscopy (AAS), and the expression of MRP2 in the membrane of hepatocyte by Western blotting was determined.

RESULTSTotal arsenic levels (including organic arsenic and inorganic arsenic) in blood and bile were significantly higher than control groups (P < 0.05) at all three different time points, especially in 2 w and 4 w group (16.8 and 13.8 fold greater than that in control). The expression of MRP2 increased 36.61%, 32.36%, 12.73% more respectively in 2 w, 4 w, 6 w groups than those in control groups (P < 0.05). The expression of MRP2 was correlated with total arsenic content in bile (r = 0.713, P < 0.05).

CONCLUSIONSBile is one of the major routes for the excretion of arsenite and its metabolites, and the overexpression of MRP2 may play an important role in the bile excretion of them at early stage.

OBJECTIVETo compare the immediate effect of moxibustion on Yanglingquan (GB 34) on body surface thermograph between the patients with myofascial pain syndrome (MPS) and healthy people.

METHODSThirty-five cases of MPS were selected in observation group and 15 cases of healthy people were in control group. ATIR-M301 medical infrared imaging device was used to observe the changes in body surface thermograph before and 15 min after moxibustion on Yanglingquan (GB 34) The qualitative analysis of picture pattern and the quantitative analysis of temperature were integrated to compare the differences between two groups.

RESULTSConcerning to the infrared thermograph expression on the back of MPS cases in observation group, the abnormal thermal zone presented in 88.6% of the cases, mostly distributed in the upper and secondly in the lower back. The spinal thermal line was broken or disappeared ine about 50% of cases. The location of pain complained by 71.4% of cases was coincident with the zone of infrared thermograph expression. There was statistical significant difference in the temperatures difference of the two sides in the upper abnormal thermal zone on the back in observation group as compared with control group (P < 0.001). Body surface thermograph on the back were impacted by moxibustion on Yanglingquan (GB 34) for either MPS patients or healthy people, especially in upper back and rhomboid fossa. Moxibustion on Yanglingquan (GB 34) increased much more apparently the temperature on the upper back in MPS patients as compared with healthy people (P < 0.05).

CONCLUSIONMoxibustion on Yanglingquan (GB34) brings the immediate improvements in the back thermograph for MPS patients.

Objective To explore the effect of associated deficiency of selenium,protein and vitamin E(VE)on the thyroid iniury and thyroid hormone metabolism of the rats in a long-term.Methods The Wistar rats were randomly divided into four groups:Group A with selenium deficiency and low protein and VE;Group B with selenium deficiency,low protein but adequate VE;Group C,adequate selenium and protein but low VE;Group D,adequate selenium.protein and VE.The rats were killed at the end of 26th week.Glutathione peroxidase(GSH-Px)activity in the rat blood and type I 5'-deiodinase activity of the rat liver were determined.The content of triiodothyronine(T3),tetraiodothyronine(T4),thyrotropic-stimulating hormone(TSH),activated oxygen(ROS)and malonaldehyde(MDA)were detected in serum. The changes of thyroid histopathology were observed under light microscope.Results ①The interactive effect of selenium+protein and VE was not significant on GSH-Px and ID I activity(F=0.003,0.871,P＞0.05),but it was significant on MDA and ROS content(F=13.057,6.706,P＜0.05 or＜0.01). ②Selenium+protein and VE could influence T3 and T4 content(F=431.977,28.271,6.570,41.419,P＜0.05).The interactive effect of selenium±protein and VE was not significant on T3 and T4 content(F=0.871,0.136,P＞0.05).Whether in the condition of low selenium and protein or supplementary,T4 contents of supplementary VE group[(79.095±12.199),(64.392±6.261)μg/L]were respectively higher than the low VE group[(61.068±6.648),(44.176±7.090)μg/L],the difference being statistically significant(t = 3.670,6.045, P ＜ 0.01). In the condition of low VE, T3[(0.718 ± 0.079)μg/L] and T4[(44.176 ±7.090)μg/L] content of supplementary selenium and protein group was lower than that in the low selenium and protein group[ (0.966 ± 0.156), (61.068 ± 6.648)μg/L], the difference being statistically significant (t = 4.568,4.916, P ＜0.01 ). With supplementary VE, T4 content of supplementary selenium and protein group[ (64.392 ± 6.261 )μg/L] was lower than that in the low selenium and protein group [(79.095 ± 12.199)μg/L], the difference being statistically significant (t = 3.033, P ＜ 0.01 ). ③Degeneration and necrosis of follicular epithelial cell were induced by diet of low selenium, protein and VE, which could be relieved by supplymentary VE. The sparseness of intracavitary glue was observed occationally in the supplementary selenium and protein but low VE group. Conclusions Long-term deficiency of selenium, protein and VE results in the decrease of the selenoenzymes of rats, which causes accumulation of the oxidative products, as well as thyroid pathological injury and thyroid hormone metabolism disorder, but supplement of adequate VE can reduce the oxidative damage in rats having low selenium and protein diet.

AIM:To explore the expression level of long non-coding RNA(lncRNA)myocardial infarction-as-sociated transcript(MIAT)in the tissues and cells of non-small-cell lung carcinoma(NSCLC), and to investigate the effect of MIAT on the function of NSCLC cell line.METHODS:Bioinformatic data in microarray dataset GSE19804 from Gene Expression Omnibus(GEO)were collected for analyzing the difference expression of MIAT between NSCLC tissues and normal lung tissues.Clinical and prognostic data in microarray dataset GSE 30219 from GEO were also collected for an-alyzing the correlation between the expression level of MIAT and the survival time of NSCLC patients.qPCR was applied to detect the expression of MIAT in 25 paired tumor tissues and corresponding adjacent normal tissues,normal lung epithelial HBE cell line and NSCLC A549,NCI-H266 and NCI-H1299 cell lines.The specific small interfering RNA for MIAT(si-MIAT group)or negative control sequence(si-NC group)was transfected into A549 cells,and flow cytometry,colony for-mation experiment and CCK-8 assay were employed to detect the proliferation of the cells in the 2 groups.The expression levels of cyclin D1 and cyclin-dependent kinase inhibitor 1A(CDKN1A)in the 2 groups were determined by qPCR and Western blot.RESULTS:In the GEO dataset GSE19804,the expression of MIAT in NSCLC tissues was significantly ele-vated compared with normal lung tissues(P<0.05).In the GEO dataset GSE30219,the overall survival time was signifi-cantly shorter in the patients with high expression of MIAT than the patients with low expression of MIAT(P<0.05).Fur-thermore,the levels of MIAT in both NSCLC tissues and cells were higher than those in adjacent normal tissues and normal cells(P<0.05).Compared with si-NC group,lower MIAT level,cell viability and cell colony number in si-MIAT group with statistical significance were observed(P<0.05).Meanwhile, compared with si-NC group, the expression of cyclin D1 in si-MIAT group was significantly decreased(P<0.05),and inversely,the expression of CDKN1A in si-MIAT group was significantly increased(P<0.05).CONCLUSION:There is high expression of MIAT in NSCLC tissues and NSCLC cells,and knockdown of MIAT expression inhibits NSCLC cell proliferation, which provides a potential target of targeted therapy for NSCLC.
