Objective To evaluate the efficacy and safety of compound azintamide enteric-coated tablet in the treatment of patients with post-cholecystectomy dyspepsia.Methods A multicentre,randomized,double-blinded,placebo-controlled trail was conducted.A total of 120 patients with post-cholecystectomy dyspepsia were divided into azintamide group (n=60) and placebo group (n＝60),taking compound azintamide enteric-coated tablet or placebo 100 mg each time,three times per day for 28 days.The score of each dyspeptic symptom (abdominal distension,loss of appetite,early satiety,belching,nausea,abdominal pain or abdominal discomfort) and total score of dyspepsia were evaluated prior to study and on the 7th,14th,21st and 28th day after treatment.The efficacy of the improvement of dyspeptic symptoms was compared between the two groups on the 28th day after treatment and the safety was evaluated.The score of the quality-of-life was compared between the two groups prior to study and on the 28th day after treatment.The t-test or chi-square test was performed for statistical analysis.Results The scores of abdominal distension,belching,nausea,abdominal pain or abdominal discomfort and the total score of azintamide group on the 7th day after treatment (5.7±3.1,3.5±2.1,0.3±0.1,3.3±1.7 and 17.9±9.6) were significantly lower than those prior to study (8.9±5.3,5.3±2.5,0.9±0.4,4.5±3.7,24.3±14.5;t=3.758,3.976,10.494,2.125 and 2.654,allP＜0.05).On the14th,21st and28thday after treatment in azintamide group,the score of each dyspeptic symptom and the total score were lower than those prior to study.The symptom of abdominal distension significantly improved on the 7th,14th,21st and 28th day after treatment in placebo group,and the score of early satiety and total score of dyspepsia were significantly lower on the 28th day after treatment compared with those before treatment.In azintamide group,the total efficacy rate was 66.7％ (40/60),which was higher than that of placebo group (38.3％,23/60) and the difference was statistically significant (x2 =9.653,P ＜ 0.01).On the 28th day after treatment,SF-NDI of azintamide group was 4.4±3.4,which was significantly lower than that of placebo group (9.6±6.0) and the difference was statistically significant (t=5.450,P＜0.01).In azintamide group there was one patient with rash on the 7th day after treatment,and in placebo group there was one patient with headache on the 14th day after treatment.The symptoms disappeared seven days after medicine withdrawal.Conclusion Compound azintamide enteric-coated tablet effectively improves dyspeptic symptoms and quality of life in patients with post-cholecysteetomy dyspepsia and has good safety.

0.05).The score of GMFM-66(55.24?11.68)after treatment had obviously improved as compared with that before treatment(39.81?13.17)in the observation group(P=0),and the score of GMFM-66(48.76?11.96)after treatment had obviously improved as compared with that before treatment(40.25?12.89)in the control group(P=0.010 3),and the effect of the observation group was significantly superior to that of control group(P=0.038 0).Conclusion ESFN combined with TOT can effectively improve the motor function in children with cerebral palsy.

Transforming growth factor-?(TGF-?) is a kind of multifunctional cytokine that regulates cell growth,differentiation,cellular senescence,apoptosis,wound healing and embryo development.As a tumor suppressor,deregulated or aberrant TGF-? signaling has been strongly implicated in human solid tumors,as well as in normal and malignant hematopoiesis.TGF? exerts an inhibitory role during the whole procedure of hematopoiesis.As a cell cycle inhibitor,it maintains cells in a quiescent state and can downregulate expression of hematopoiesis activators and oncoproteins.In malignant hematopoiesis,altered expression of coactivators or corepressors involve in TGF-?-induced transcriptional responses and loss/disruption of TGF-? target gene expression.Then malignant cells grow and differentiate abnormally.In acute promyelocytic leukemia,PML-RAR? may inhibit TGF-? signaling through inhibition of cPML and nPML.Degradation of PML-RAR? by ATRA restores this signaling pathway.

Objective By simulating a high-glucose condition of peritoneal dialysis (PD)fluid,to explore the effect of high glucose on the expression of leptin and its relationship with peritoneal angiogenesis.Methods Adipocytes differentiated from 3T3-L1 were divided into high glucose group (139 mmol/l glucose) and high mannitol group.Leptin levels in supernatant collected at 0 h,12 h,24 h and 48 h were measured by ELISA.Endothelial cells (ECs) were respectively cultured with normal glouse,high glucose,high mannitol condition,supernatants of adipocyte induced by normal glouse,high glucose and high mannitol,high glucose supernatants+leptin antibody,and high mannitol supernatants + leptin antibody.Tubular structure formation and migration of ECs were detected.Results Adipocytes exposed to high glucose for 48 h produced more leptin as compared with control group,high mannitol group,12 h-high glucose group and 24 h-high glucose group (all P ＜ 0.05).Compared with ECs in normal group,ECs in high glucose had less tubular structure formation and increased migration (all P ＜ 0.01).Compared with those of ECs in high glucose,the tubular structure formation and the migration of ECs in adipocyte supernatants induced by high glucose had increased (all P ＜ 0.01),and these effects were reduced by leptin antibody (all P ＜ 0.01).Conclusion There is an up-regulation of leptin in adipocytes exposed to high glucose,which may be an alternative way to prevent peritoneal angiogenesis.

Objective To assess the CT image quality of the pure ground glass nodule(pGGN)in chest phantom by using different field of view(FOV)and matrix.Methods CT(Philips Brilliance 128 spiral CT)scans were performed on chest phantom containing 9 artificial pGGNs(diameter≥5 mm)in 3 different FOV (50 mm,150 mm,300 mm ),and were reconstructed in 2 different matrix(512×512, 1 024×1 024),standard kernel.Recorded the CT values and standard deviations (SD)of the nodules and surrounding regions in different FOV and matrix,and calculated the mean standard deviation(MSD),contrast noise ratio (CNR)and signal noise ratio (SNR),then compared the difference among them.Two radiologists assessed the image quality of the pGGNs in blind method respectively,then evaluated the coherence between them using Kappa testing.Results The coherence of 2 observers was substantial or almost perfect.No significant differences were found on MSD,CNR and SNR in different FOV (P value>0.05)when matrix was kept,whereas the visibility of the nodules improved with the FOV changing smaller.And there were significant differences all on MSD,CNR and SNR by using different matrix when FOV was kept.The MSD increased and the CNR,SNR decreased in high-resolution group.The visibility of the pGGNs was not improved obviously in high-resolution group.Conclusion The image quality of the pGGN(diameter≥5 mm)won’t be changed by using smaller FOV when matrix is kept ,but the visibility will be improved with the FOV changing smaller.When FOV is kept,the MSD increased and the CNR,SNR reduced in high-resolution group,but the visibility will not be improved obviously compare to the standard resolution group.

Objective To analyze the effect of eukaryotic plasmids containing wild (sense) or anti- sense methylenetetrahydrofolate reductase (MTHFR) gene on cell viability and transcription level of tumor related genes in human gastric cancer cell line.Methods Human gastric cancer cell line MKN-45 was cultured.Recombinant plasmids containing wild MTHFR (W) or antisense MTHFR (A) gene, pCMV-W and pCMV-A,were constructed.Then pCMV-W,pCMV-A and pCMV blank plasmid were transfected into MKN45 cells respectively by using lipofect.Cell viability was analyzed by 3-(4,5-bime- thylthiazolyl-2)-2,5-diphenyhetrazolium dromide(MTT).The transcription levels of Dnmt 1,c-myc, p21~(WAF1) and hMLH1 genes were detected by real-time polymerase chain reaction(PCR).Results Cell vi- ability remarkably increased in those transfected with wild MTHFR (P＜0.01),which was contrary to those transfected with antisense MTHFR(P＜0.01).The expression of those tumor related genes mRNAs were all remarkably decreased in the MKN45-W cells in comparison with those in the MKN45-pCMV cells.No significant difference in the expressions of those tumor related genes mRNAs were found between the MKN45 cells transfected with pCMV-A and blank pCMV.Conclusion MTHFR influences cell viability and the expres- sion level of tumor related genes in human gastric cancer cell line MKN45.
