Background and purpose:Runt-related transcription factor 3 (RUNX3) has a signiifcant relation with gastric cancer. Many researches have confirmed that rs760805 AA can increase the risk of gastric cancer. The purpose of the study was to investigate the relationship between the rs760805 polymorphism of the RUNX3 gene and gastric cancer. Methods: The rs760805 genotypes were determined by PCR-based DNA sequence measuring analysis and direct DNA sequencing in 310 incident cases with gastric cancer and 327 controls recruited in Shandong. Results:The frequency of TT genotype was 15.16%in gastric cancer patients and 20.49%in normal controls, and the corresponding percentages for AT and AA genotypes were 48.39%and 36.45%, and 52.60%and 26.91%, respectively. Compared to TT genotype, AT genotypes were associated with an increased risk of gastric cancer (OR=1.24, 95%CI`:0.81-1.92;OR=1.83, 95%CI:1.15-2.92). Conclusion:The rs760805 polymorphism of the RUNX3 gene is associated with increased susceptibility to gastric cancer.

AIM: To investigate 1) the role of transforming growth factor-?_1(TGF-?_1) and macrophage infiltration during the development of myocardial fibrosis(MF) in rats after myocardial infarction(MI);and 2) mechanisms of MF post-MI and the inhibitory effect of angelica.METHODS: Sprague-Dawley(SD) rats were subjected to MI by ligating the left anterior descending coronary artery.The animals were randomly divided into three groups: sham,MI and MI+angelica.After 24 hours of ligation,rats received angelica(20 mL?kg~(-1)?d~(-1),ip) or saline.Left ventricular hemodynamics were measured and rats were killed at week 1,week 2 and week 4, respectively.Collagen content,macrophage infiltration and TGF-?_1 expression were examined in the non-infarcted area.RESULTS: ① In MI group,the numbers of macrophage and TGF-?_1 expression were significantly upregulated compared to sham at week 1 post-MI and remained elevated at week 4(P

Objective To investigate the effect of curcumol on apoptosis of human gastric carcinoma cell line BGC823 and the molecular nechanisms.Methods BGC823 cells were cultured and treated with different curcumol concentration (12.5,25,50 and 100 mg/L) for 24 h and 48 h,and the growth inhibition were tested by thiazolyl blue terazolium bromide (MTF) assay.Flow cytometry (FCM) were used to measure the cell apoptosis rate and cell cycle of BGC823 cells.Caspase-3 activity was assessed by colorimetric assay.Cells treated with 100 mg/L curcunol for 48 h were collected and subjected to RTPCR and Western blot assays for the expression of Caspase-3,Bcl-2,Bax and Survivin.Results There was a time-and dose-dependent inhibition of cell proliferation of BGC823 cells by curcumol.Tbe cells in G0/G1 phase increased,and in S phase decreased on exposure to curcumol for 24 h.FCM analysis also indicated that the apoptosis rate of BGC823 cells increased in dose-dependent manner (P ＜ 0.05).Curcumol increased the activity of Caspase-3 dose-dependently (P ＜ 0.05).RT-PCR and Western blot indicated that curcumol decreased Bcl-2 and Survivin expression as well as increased Caspase-3 and Bax expression (P ＜ 0.05).Conclusions Curcumol inhibits BGC823 cell growth,arresting cells in G0/G1 phase and inducing cell apoptosis.The mechanism may be related with increasing the activity of Caspase-3,down-regulating the expression of Bcl-2 and Survivin,and up-regulating the expression of Caspase-3 and Bax.

Objective To evaluate the impact of sequence on the quality of bowel preparation in patients with anesthesia for same-day sequential bidirectional endoscopy and propose the optimal procedural sequence.Methods Single center blinded randomized observational study.Sixty-five patients were randomized to either the gastroscopy-first group or the colonoscopy-first group.Bowel cleanliness according to Boston bowel preparation scale (BBPS) scores were evaluated,also done the propofol dosage,caecal intubation time,procedure duration and complications.Results The BBPS score of entire colon showed no difference (6.72 ± 1.34 vs.6.89 ± 1.50,P =0.638),but the BBPS of ileal-cecum portion was higher in the colonoscopy-first group (1.21 ±0.54 vs.1.55 ±0.73,P =0.035).The total procedure time,propofol dosage and complications were similar between the two groups.Conclusion The bowel cleanliness of ileal-cecum portion in colonoscopy-first group is better than that of gastroscopy-first group during sequential bidirectional endoscopy in patients with propofol sedation.We propose colonoscopy first in patients with suspicious ileal-cecum lesion.

Objective To investigate the subtype distribution and changing trend of human immunodeficiency virus (HIV)-1 strains among men who have sex with men (MSM) during 2005-2011 in Beijing.Methods Five serial cross-sectional surveys of MSM were conducted in the year of 2005-2006,2007,2008,2009,and 2010-2011 in Chaoyang district of Beijing.Whole blood samples were collected and then RNA was extracted.HIV-1 gag gene was characterized by reverse transcriptase and nested polymerase chain reaction (RT-PCR) amplification,DNA sequencing,and phylogenetic analysis of viral sequences to determine the HIV-1 subtypes.Results Phylogenetic analysis of the sequences revealed that the predominant subtypes of HIV-1 gag gene included subtype B,CRF01_AE and CRF07_BC.And CRF15_01B was detected from the year of 2008.In addition,significant changes of the distributions of subtypes and CRFs occurred from 2005 to 2011 in HIV+ MSM.Subtype B showed a significant decreased trend,while the proportions of CRF01 _AE and CRF07_BC significantly increased in the 7-year period,particularly that of CRF01_AE.Conclusions The substantial changes are observed in the diversity of HIV-1 strains circulating among MSM in Beijing during a 7-year period.

Objective To investigate the correlation between serum bone metabolism biomarkers and bone mineral density (BMD) in chronic kidney disease (CKD) patients with different stages. Methods Seventy-eight CKD patients were enrolled in this study and were assigned to different groups according to their ereatinine clearance (Cer). Patients with Cer ≥ 15 ml/min were divided into 4 groups based on clinical CKD 1-4 stage standard, and those with Ccr<15 ml/min were divided into two groups of hemodialysis (HD) and non-HD. Their levels of serum calcium, phosphorus, alkalinity phosphatase (ALP), urea, Ser, osteocalein (gla-protein, OC), calcitonin (CT), intact parathyroid hormone (iPTH), osteoprotegerin (OPG) and BMD were detected respectively. Results (1) The serum levels of OPG, iPTH and phosphorus increased significantly in stage 3, 4, 5, respectively (P<0.01), and serum OPG level was elevated to (5.1±1.34) ng/L after HD, which was significantly higher than (3.35±0.76) ng/L before HD (P<0.05). The levels of serum OC, CT, calcium, ALP were not significantly different among patients with different CKD stages, while the level of OC was elevated in HD patients (P<0.05). The femoral WARDS triangle BMD of CKD stage 4 patients decreased to 0.77±0.09, which was less than the value of CKD stage 1 patients (P<0.01), with litde influence from hemodialysis treatment. (2) The level of serum OPG was positively correlated with the levels of serum phosphorus, iPTH, OC (r = 0.51, 0.39, 0.36,all P<0.01), and it was negatively correlated with the level of Ccr (r =-0.70, P<0.01). The femoral WARDS triangle BMD was negatively correlated with the levels of iPTH, OC, phosphorus and OPG (r =-0.59,-0.51,-0.45,-0.48, all P<0.05). Conclusions Most of serum bone metabolism biomarkers change according to the declined level of Cer. Compared with serum phosphorus, the levels of iPTH, BGP and femoral WARDS triangle BMD, serum OPG may be early diagnosticmarkers of renal osteodystrophy in CKD patients.
