Objective To study the influence of short hairpin RNA-mediated inhibition of APRIL gene on proliferation,invasion and metastasis of human colon carcinoma SW480 ceils in vitro. Methods After treatment with shRNA, the expression level of APRIL protein in human colon carcinoma SW480 cells was detected by western blotting. And cell adhesion, cell migration and cell invasion of SW480 cells transfected with sh637 were analyzed respectively as compared with non-transfected SW480 cells and mocktransfectant. Results The expression of APRIL protein in SW480 transfected with sh637 were significantly lower than mock-plasmid groups and untransfected ones (F=42.15, P=0.00). Cell proliferation was markedly inhibited, compared with untransfected groups and negative control ones (F=24.76, P<0.05).And the average absorption of cell adhesion in transfected groups, mock-plasmid and non-transfected ones were 0.343, 0.409, 0.412, respectively. Cell adhesion decreased 39% compared with untransfected groups. Similarly, there was significant difference for cell migration (F=65.53, P<0.01) between transfected groups (The average ceil number in exposed area to migrate was 47.89±13.16) and nontransfected (98.78±23.26) as well as mock-plasmid ones (108.01±39.11). Then, in view of the average absorption of cell invasion between transfected groups(0.58±0.10) and non-transfected (0.94±0.23) as well as mock-plasmid ones(1.11±0.21), a prominently difference for cell invasion was also found between them (F=5.771, P<0.05). Conclusion The results suggest APRIL has a proliferation-inducing effect and probably be involved in cell invasion and cell metastasis of colon carcinoma and it could enhance capacity of invasion and metastasis of SW480 cells.

Objective To explore the best vibration frequency for activating human muscles.Methods Nineteen healthy college students accepted vibration stimulation at frequencies between 10 and 50 Hz.Surface electromyograms (sEMG) were recorded.The subjects were sitting,standing,squatting (knee flexion 30°) and recumbent.Their left anterior tibial muscles and the medial heads of the gastrocnemius were targeted as test muscles.The vibration stimulation point was on the surface of the left distal tibia.The sEMG characteristics of the calf muscles were analyzed under vibration stimulation at different frequencies. ResultsThe leg muscles were activated significantly at all vibration frequencies,but the sEMG values of the anterior tibialis were significantly different at different frequencies,except for among 30 Hz,40 Hz and 50 Hz in any position.The gastrocnemius sEMG values were not significantly different at different frequencies. ConclusionVibration at 30 to 50Hz may be the normal human muscle activation frequency.

Objective To establish a method of SYBR Green Ⅰ FQ-PCR for detecting the expression of miR-202 in peripheral blood mononuclear cells ( PBMC ) and analyze the expression of miR-202 and its clinical significance in MM.Methods Reverse transcription was performed with specific stemloop primer for miR-202,and then FQ-PCR was used to detected the expression of miR-202 in 21 MM patients and 20 healthy people.Data was presented as mean ± standard deviation ( (x) ± s ).Non-parametric Mann-Whitney test was used to analyze the difference between MM group and control group.In addition,1∶ 125 dilution of one test sample was detected by repeated 5 times,and the same sample was tested one time a day for 3 days,repeated 5 each time.The assessment of repeatability of measurements was done by calculating standard deviation and variation coefficient from threshold cycle (Ct).Results FQ-PCR detection of miR-202 in PBMC was amplified by the standard S-curve,with a single melting curve peak and no complex peak,which showed good specificity.The assay showed good reproducibility (intra-assay coefficient 1.2％ and inter-assay coefficient 3.2％ ) and high sensitivity ( 12.8 pmol/μ1).The expression of miR-202 in MM was 0.014 ( 0.007 - 0.221 ) and 1.844 ( 0.162 - 3.966 ) in normal controls.The expression level of miR-202 was significantly higher in MM than in normal controls (U =48.000,P ＜0.01 ).Conclusions FQ-PCR provide us a rapid,sensitive and specific method for detection of miR-202.The expression level of miR-202 is higher in MM than in normal controls.It is possible to play a role in MM progress and may be a useful marker to evaluate the development and treatment of MM.

Objective To investigate the clinical value of circulating miR-125b-5p in coronary atherosclerotic heart disease.Methods With case-control study,80 cases of coronary atherosclerotic heart disease were recruited in Affiliated Hospital of Nantong University from February 2014 to august 2015.According to coronary angiography result they were divided into two groups: there are coronary artery stenosis group(n=49)and control group(n=31).All patients were also divided into non-ST-segment elevation myocardial infarction and ST-segment elevation myocardial infarction group(n=35),unstable angina group group(n=25),stable angina group(n=20).The level of miR-125b-5p before coronary angiograph was detected.By independent sample t test and variance analysis,the levels of miR-125b-5p were compared between the groups of coronary artery stenosis and the group with no stenosis of the coronary artery,the coronary artery lesions in each group,and between the various types of coronary atherosclerotic heart disease respectively.Results MiR-125b-5p expression level of Coronary artery stenosis group(0.35±0.10)was lower than that in group coronary artery with no stenosis(0.95±0.12),the difference was statistically significant(t=24.179,P<0.000 1).With the increase in the number of diseased coronary arteries,miR-125b-5p expression level decreased gradually.There is also statistical significance(t=8.399,P<0.000 1; t=13.067,P<0.000 1)in miR-125b-5p expression among NSTEMI+STEMI,UA and SAP groups.miR-125b-5p expression level was negatively correlated with Gensini score(R2=0.822,P<0.05).The area under the ROC curve(AUC)of miR-125b-5p was 0.86(95％CI 0.67-0.90),and 0.66 was the optimal cut-off value with sensitivity of 81.22％and specificity of 78.62％.Conclusions With the increase of the number of stenosis,plasma miR-125b-5p expression level decreased gradually.The expression level of miR-125b-5p was negatively correlated with the Gensini score of coronary artery,which indicated that the expression level of miR-125b-5p may be a potential biomarker that can reflect the lesion degree of coronary artery.

Objective To investigate the action and mechanism of NF-κB pathway in up-regulating B cell-activating factor receptor (BAFF-R) expression in multiple myeloma cells induced by IFN-γ.Methods Activated NF-κB were detected with Western blot, while the expression of BAFF-R were measured with RT-PCR and ELISA, and investigated the effect of BAY11-7082 on transcription of BAFF-R mRNA and translation of protein in multiple myeloma cells stimulated by IFN-γ. Results IFN-γ can induce the degradation of IκB-α in time-dependent and dosage-dependent manner, and up-regulated BAFF-R expression in multiple myeloma cells. BAY11-7082, an NF-κB inhibitor, inhibited not only the transcription of BAFF-R mRNA but also the protein of regulated by IFN-γin dosage-dependent manner. Conclusion NFκB may play an important role in high expression of BAFF-R in multiple myeloma cells induced by IFN-γ.

OBJECTIVE: To study the change of endogenous hydrogen sulfide (hydrogen sulfide, H2S) and its rate-limiting enzyme Cystathionine-gamma-lyase (CSE) in allergic rhinitis through guinea pigs with intervention treatment. METHOD: Twenty-four guinea pigs were divide into 4 groups at random, one group were models of allergic rhinitis (AR) which were established by using ovalbumin, the second group were treated with NaHS after sensitized, the third group were treated with Propargylglycine (PPG) which was suppression of CSE after sensitized, and the last group were treated with saline for control. The concentration of eotaxin of nasal lavage and H2S in plasma were recorded, and then the expression of CSE in nasal mucosa was determined by real-time fluorescence RT-PCR. RESULT: The concentration of eotaxin in nasal lavage of sensitized group were higher than those of control (P < 0.01), and concentration of H2S in plasma and expression of CSE in nasal mucosa were lower than control (P < 0.05). The concentration of eotaxin decreased when treated with NaHS and increased when treated with PGG (P < 0.05). Level of H2S in plasma and expression of CSE increased when treated with NaHS and decreased when treated with PGG (P < 0.05), and the level of H2S was positive linear correlate with the expression of CSE. CONCLUSION Endogenous H2S perhaps plays a significant role in the pathogenesis of allergic rhinitis, and it was mainly regulated by CSE.
