Objective To explore the diagnosis, treatment and prognosis of acute perforation of gnstric cancer. Methods The clinical data of 24 patients with acute perforation of gastric cancer who had been admitted to Guangzhou General Hospital of PLA from July 1996 to December 2008 were retrospectively analyzed. Results Of all patients, 4 were treated by perforation repair, 2 by perforation repair combined with gastrojejunostomy, 11 by palliative subtotal gastrectomy, 2 by radical gastrectomy, and 5 by radical gastrectomy after perforation repair. The mean survival time of patients treated by perforation repair, perforation repair combined with gastro-jejunostomy, partial gastrectomy and radical gastrectomy were (4±5), (6±9), (12±7), and (25±9) months, respectively. Conclusions Early diagnosis and reasonable operation are the keys to decrease the morality and increase life quality for patients who suffered from acute perforation of gastric cancer. Different pathologic stages maybe an important factor in deciding the prognosis.

Objective To study the effect of acute lymphoblastic leukemia (ALL) children bone marrow mesenchymal stem cells (MSCs) on the resistance of K562cell atd mechanism in vitro.Method MSCs were obtained from AL children bone marrow after derivation, cultivation and identification.The coculture of MSCs and K562 and K562 suspension were established.Effects of MSCs on the growth of K562 cells were investigated in vivo.The two kinds of cells treated with different concentration of adriamycin (ADM) and the rate of apoptosis was evaluated by flow cytometry.Cell cycle was determined by flow cytometry.RT-PCR was used to detect Bcl-2 and Bax in K562 cells.Result Compared with the cell growth curve of K562 alone, the K562 cell co-cultured with MSCs grew slower and the exponential phase of growth was not obvious.The apoptosis index of the K562 cells co- clutured with MSCs was (9.19 ±0.53)% examined by flow cytometry, and that of the K562 cells alone was 4.00 ± 0.37% respectively( P ＜ 0.05 ).The percentage of cells at G0/G1 phase was (50.2 ± 2.26) % and that at S phase was (37.03 ± 3.50) % in the group of K562 alone, but those of the K562 cells co - cultured with MSCs were (80.95 ± 3.83) % and ( 17.40 ± 1.50)% respectively( P ＜0.05).The result of RT-PCR suggested expression of Bcl-2/Bax of the K562 cell co-cultured with MSCs was higher than K562 alone.Conclusion ALL children MSCs suppressed the growth of K562 cell in vitro.Adhesion made K562 depress sensitive to ADM.The mechanism was perhaps caused by adhesion with MSCs, K562 cell cycle was changed and related to Bcl-2 gene high level expression.

Objective To knock down angiopoietin-1 expression in human gastric cancer cell line BGC-823 and to observe its effect of reversing tumor invasion. Methods siRNA sequence fragments was designed to target angiopoietin-1 and transferred into human gastric cancer cell line BGC-823. RT-PCR was used to assess the transcription level of angio-poietin-1 mRNA, then western blot and immunofluorescence were used to examine the expression level of three invasion-as-sociated proteins include integrinβ1, CD44V6 and Ang-1. Cell adhesion ability was evaluated by cell adhesion assay and cell invation was determined by matrigel and transwell plastic dual-chamber culture system. Results Ang-1 mRNA was knocked down by siRNA showed by RT-PCR. The expression of integrinβ1, CD44V6 and Ang-1 were significantly lower than control group(P<0.05), so did the cellular adhesion and invasion abilities(P<0.05). Conclusion Knocking down angiopoietin-1 by siRNA can reverse invasion of human gastric cancer cell line BGC-823 and may provide new ideas and reference for gene therapy of gastric cancer in the future.

Objective To study the emmetropization in guinea pig eyes during the normal development from birth in order to provide theoretical basis to use guinea pigs as model for research on near-sightedness.Methods Sixty-four guinea pigs were assigned to 8 groups (n=8,4 male/4 female).Each group underwent a series of ocular examinations at one of the 8 time-points (0,1,2,3,5,7,9 and 11 weeks),including refraction(R),radius of corneal curvature (RCC),depth of anterior segment(AS),thickness of crystalline lens (CL),length of vitreous chamber (VC)and axial length (AL).Pooled results from both eyes of the same animals with mixed sexes can be used for further assessment of the emmetropization with the associated biometrical changes of the eye.Correlations were made between RCC,AS,CL,VC,AL and R. Results There were no significant differences between the right eye and left eye or between male and female in results of all the examinations. The refraction at birth was (+5.25?0.22 )D in guinea pigs.This value rapidly decreased during the first 3 weeks,approaching(+1.34?0.61) D by 11 weeks.There was no significant difference in refraction between 9 and 11 weeks (P= 0.215). The RCC was (3.23?0.01) mm at birth,AS was (1.20?0.00) mm at birth,CL was (2.72?0.02) mm at birth and VC was (3.27?0.01) mm at birth,they increased within the first 3 weeks despite a transient decrease in the RCC within the first week.Such an increase continued except the AS which became constant after 3 weeks.The VC was more correlated to the emmetropization (r=-0.818,P
