Objective To investigate the expressions of guanylyl cyclase-c(GC-C) and caudal-type homeobox transcription factor 2 (CDX2) in human gastric tissues and precursor lesions and its significance. Methods The cancerous and paracancerous (5 cm from cancer lesion )samples from 30 cases of gastric cancer and 32 samples including 23 intestinal metaplasia and 9 dysplasia were collected. The mRNA expressions of GC-C and CDX-2 were detected by reverse transcriptase-polymerase chain reaction (RT-PCR) and proteins of GC-C and CDX-2 were measured by using Western blot and immunofluorescence methods. Results The mRNA expressions of GC-C and CDX-2 were absent in paracancerous tissues, but were 66.7% and 63.3% in cancerous tissues, respectively(P=0. 000). The Western blot indicated that expressions of GC-C and CDX-2 were 19/30 and 17/30 in cancerous tissues, but absent in paracancerous tissues(P=0. 000). The immunofluorescence examination revealed that GC-C and CDX-2 expressions were 39.1% and 39.1% in intestinal metaplasia, 55.6% and 55.6% in dysplasia, and 56.7% and 60.0% in cancerous tissues, respectively, but absent in paracancerous tissues. Moreover, expressions of GC-C and CDX-2 showed a statistical difference between intestinal-type and diffuse-type of gastric cancer (P＜ 0.05) ,but had no correlation with age, sex, size of the lesion, clinical stage and lymphnode metastasis. The positive correlation was found in expressions of GC-C and CDX2 between intestinal metaplasia and cancerous tissues(r=0. 4524 and 0. 3845, P= 0. 037 and 0. 0408, respectively). Conclusions The over expressions of GC-C and CDX2 in human gastric cancer is associated with precursor lesions and may play an important role in the carcinogenesis of gastric cancer. The examination of GC-C and CDX2 expressions will be helpful in diagnosing gastric cancer and precursor lesions.

Objective To evaluate the influence of right ventricular outflow tract septal ( RVS) pacing with right ventricular apical ( RVA) pacing on left ventricular remodeling and brain natriuretic peptide ( BNP). Methods Sixty patients with indication of pacemaker implantation were randomized into two groups, RVA group and RVS group. BNP was measured with ELISA, and echocardiography was performed to measure the left ventricular end diastolic volume ( LVEDD), left ventricular end systolic volume ( LVEDV) and left ventricular ejection fraction (LVEF) at pre-operation,and after 6,12,24 months pacing. The difference of cardiac remodeling and BNP in the two groups was observed. Results Compared to BNP at pre-operation (( 60. 2 ± 15. 7 ) ng/L) , BNP increased significantly in the RVA group at the 6th,12th and 24th month after operation( ( 108. 2 ±29. 8) , ( 190. 3 ±46. 7) ,(308. 2 ±56. 5)ng/L,respectively) (P <0. 05). In the RVS group,BNP increased only at 24 months after pacing ( (75. 2 ± 15. 8) ng/L vs. (63. 9 ± 15. 1 ) ng/L) (P < 0. 05). There was significant difference on BNP between the two groups. LVEDD,LVEDV increased,LVEF declined at 12 months after pacing in the RVA group,which were not observed in the RVS group. There was significant difference on LVEDD,LVEDV and LVEF in the RVA group (P< 0. 05) between the 12th month and pre-operation,and there were no significant difference in the RVS group (P > 0. 05). Conclusions Compared to RVA pacing,RVS pacing was more beneficial to improve heart function,prevent cardiac remodeling and decline the activation of nerve-endocrine.
