Aim To evaluate the bioequivalence of two preparations of gliclazide in healthy volunteers.Methods The concentration of gliclazide was measured by high performance liquid chromatography(HPLC) after a single or multiple dosage of gliclazide sustained released tablet in healthy volunteers.The pharmacokinetic parameters of the two preparations were calculated by 3P97 program.LnAUC0~∞,lnAUC0~72 and lnAUC0~? were used to evaluate the bioequivalence of the two preparations with analysis of variance and two one-side t-test.Results Both the gliclazide extended action tablet were best fitted to one-compartment model.The main parameters of the tested and reference gliclazide after a single dose were as follows:Cmax(2.07?0.61) and(2.26?0.61)mg?L-1;Tmax(5.10?0.55)h and(5.05?0.51)h;T12Ka(1.50?0.26)h and(1.52?0.27)h;T12Ke(8.89?1.56)h and(8.68?1.72)h;MRT(22.63?1.01)h and(22.38?0.93)h;AUC0~72(39.19?8.03)mg?h-1?L-1 and(39.26?8.37)mg?h-1?L-1;AUC0~∞:(45.80?9.51)mg?h-1?L-1 and(45.57?9.76)mg?h-1?L-1;F0~72 and F0~∞(100.19?6.22)% and(100.85?5.88)%,respectively.The main parameters of the tested and reference gliclazide after multiple dose were as follows:Cmax(4.83?0.86)mg?L-1 and(4.69?0.64)mg?L-1;Cmin(0.68?0.14) mg?L-1 and(0.66?0.12)mg?L-1;Tmax:(4.10?0.45) h and(4.10?0.55)h;T12Ka:(2.03?0.53)h and(2.04?0.40)h;T12Ke:(7.24?0.87)h and(7.09?1.14)h;MRT(9.17?0.30)h and(9.19?0.37)h;AUCSS:(41.62?6.48) mg?h-1?L-1 and(42.18?6.03)mg?h-1?L-1;Cav:(1.73?0.27)mg?L-1 and(1.76?0.25)mg?L-1;DF(240.85%?34.07)and(230.23%?24.80%) respectively.The relative bioavailability was(98.60?4.60)%.The AUC0~T,AUC0~∞ or AUCSS,Cmax and Tmax were bioequivalent between the two preparations.Conclusion The tested and reference gliclazide sustained released tablet are bioequivalent.

Objective To analyze the clinical factors for pathologic complete response ( pCR) after preoperative neoadjuvant chemoradiotherapy ( neo?CRT) for locally advanced rectal cancer. Methods From 2005 to 2012, 297 patients with locally advanced rectal cancer and complete clinical data were enrolled as subjects. Those patients were diagnosed with biopsy and treated with neo?CRT ( radiotherapy by 3?dimonsional conformal radiotherapy or volumetric?modulated arc therapy) followed by radical surgery. The logistic regression model was used for the multivariate analyses of the correlation of pCR with age, gender, distance between tumor and the anal verge, serum level of carcinoembryonic antigen ( CEA ) before treatment, hemoglobin level before treatment, cT staging, and cN staging. Results In all patients, 78 ( 26?7%) patients had pCR after treatment. The numbers of patients with pCR were 42( 34?4%) in patients with stage T1?T3 disease and 37(21?1%) in patients with stage T4 disease. In the patients with serum CEA levels no higher than 5?33 ng/ml, 55(36?4%) had pCR after treatment, while in the patients with serum CEA levels higher than 5?33 ng/ml, only 24( 16?4%) had pCR. The univariate analysis revealed that age, gender, distance between tumor and the anal verge, anemia before treatment, or cN staging were not related to pCR. The multivariate analysis showed that stage cT1?T3 and a serum CEA level no higher than 5?33 ng/ml before treatment were influencing factors for pCR after neo?CRT for locally advanced rectal cancer ( P=0?031,P=0?000) . Conclusions The clinical staging and the serum CEA level before treatment are influencing factors for pCR after neo?CRT for locally advanced rectal cancer. The serum CEA level before treatment can be considered as a predictor of pCR after neo?CRT for locally advanced rectal cancer.

Objective To investigate the role of long noncoding RNA-AJ227913 in the pathogenesis of primary gout arthritis (GA). Methods The subjects were divided into three groups:30 acute gout patients (AGA), 30 non-acute gout patients (NAGA), 30 healthy controlsand 30 hyperuricemia patients (HUA). Real-time quantitative polymerase chain reaction (RT-qPCR) was employed to examine the expression of AJ227913 in peripheral blood mononuclear cells(PBMCs) from four groups. 100 μg/ml monosodium urate (MSU) was used to stimulate the peripheral blood of NAGA and healthy controls patients. Then the expression ofAJ227913 was detected by RT-qPCR. Kruskal-Wallis test, Mann-Whitney test, Spearman correlations were used for statistical analysis. Results The expression level of AJ227913 in the AGA group (0.0557 ±0.0156) was higher than that in the NAGA group (0.0223±0.018) and healthy controls group (0.0038±0.0013). There was significant difference between the NAGA group and healthy controls group (P>0.05). Compared with the control group, the expression of AJ227913 in NAGA group which were stimulated by MSU was significantly increased. The Spearman correlation analysis found that the AJ227913 expression levels in GA groups were correlated with UREA (r=0.608, P<0.01), CREA (r=0.337, P<0.05), CYSC (r=0.422, P<0.01). Conclusion Altered expression of AJ227913 may be involved in the inflammatory process of GA and the balance of uricacid.

UNLABELLEDObjective To compare the impact of right ventricular apical (RVA) versus right ventricular outflow tract (RVOT) pacing on left ventricular systolic synchronization.

METHODSSixty patients were prospectively recruited and randomized into RVA group (n=30) with the right ventricle leads placed in the RVA and RVOT group (n=30) with right ventricle leads placed in the septum of the RVOT. Speckle tracking imaging was performed with 100% ventricle pacing to measure the differences in the time to maximum left ventricle (LV) radial strain.

RESULTSIn RVA group, the difference in the time to 6-segment maximum LV radial strain after pacing was 105.27 ± 19.74 ms, significantly greater than that in RVOT group (41.65 ± 12.17 ms, P<0.001). The standard difference of time to 6-segment maximum LV radial strain was also significantly greater in RVA group than in RVOT group (42.71 ± 17.63 vs 17.63 ± 5.62 ms, P<0.001).

CONCLUSIONLeft ventricle systolic synchronizaition after RVOT pacing is superior to RVA pacing.
