Objective To investigate the inhibitory effect and the mechanism of endostatin on human gastric carcinoma model in nude mice. Methods Athymic mice were injected by in vitro-cultured SGC-7901 human carcinoma cell strain to observe the inhibitory effect of endostatin. Real time fluorescent quantitative PCR and immunohistochemistry stain were used to quantify the expression levels of Bcl-2 and Bax genes both on mRNA and protein levels. Results The average tumor volume in endostatin group was statistically smaller than control group (P<0.05). The inhibitory rate on the 7~(th), 10~(th), 13~(th), 16~(th) and 19th day was 26.2%, 47.7%, 38.9%, 45.8% and 51.7%, respectively. The results of real time fluorescent quantitative PCR demonstrated that mRNA expression of Bcl-2 in endostatin group was obviously lower than it in control group (P<0.05), however, the expression level of Bax had no statistical difference between these two groups (P>0.05). The results of immonohistochemistry were consistent with PCR. Conclusions Endostatin can inhibit the proliferation of SGC-7901 human gastric carcinoma in athymic mouse model, and the mechanism involves the suppression of Bcl-2 expression.

Objective To explore effect of Simotang on gastrointestinal motility and expression of vasoactive intestinal peptide(VIP) in the hypothalamus, spinal cord and duodenum of chronical stressed mice. Methods Mice were randomly divided into normal, stress and Simotang group( n= 10 in each group), and given a variety of unpredictable chronic mild stress. After 21 days gastric emptying and intestinal propulsion function were measured,the expression of VIP was detected by immunohistochemistry and RT-PCR. Results Compared with mice in normal group( (49.81 ± 8.56)%; (51.02 ± 5.11 )% ), chronic stress increased gastric residual rate( (61.53 ±8.71 ) %; P < 0.05 ) and reduced small intestine propulsion rate ( ( 31.79 ± 2.38 ) %; P < 0. 05 ). There were differences in expressions of VIP positive cells and mRNA in duodenum( (8.8 ± 1.1 )/mm2 and(0. 58 ±0.03) ),hypothalamus ( ( 12.9 ± 1.5 )/mm2 and (0.81 ± 0. 07 ) ) and spinal cord ( ( 12.1 ± 1. 2)/mm2 and (0.76 ± 0.02) )in chronic stress group compared with normal group( (6.5 ± 0. 9)/mm2 and (0.43 ± 0. 04);( 10.8 ± 1.3 )/mm2and (0.57 ± 0.03 ); (9.3 ± 1.5 )/mm2 and (0.53 ± 0. 02 ) respectively). There was not difference in gastric residual rate (52.93 ± 9.15 )%, small intestine rate(48.98 ± 4.38 )% and expressions of VIP positive cells and mRNA in duodenum ( (6.7 ± 0.9)/mm2 and (0.48 ± 0. 05 ) ), hypothalamus ( ( 10. 6 ± 1.4 )/mm2 and ( 0. 61 ± 0. 05 ) )and spinal cord ( (9. 1 ± 1.3)/mm2 and(0.55 ± 0.05 ) ) in Simotang group compared with those in normal group (P > 0.05 ), but there were decreased compared with those in chronic stress group (P < 0.05 ). Conclusion Simotang can regulate expressions of VIP in duodenum, hypothalamusand spinal cord in chronically stressed mice.

Objective To explore the situation of return-to-work (RTW) and its related factors in female injured works. Methods The da-ta of the basic information, counseling record and follow-up record after discharge were collected from social rehabilitation department in our center. The main influencing factors were analyzed by single factor analysis and two classification Logistic regression. Results 232 ob-jects were collected, among which, 149(64.2%) subjects had returned to work, and the median of absence time was 206.5 days. Single factor analysis indicated that their age, marriage, absence time and educational level were not correlated with the outcome of women injured work-ers' employment (P>0.05). However, place of social insurance, household register and injury severity correlated with the outcome (P<0.05). Conclusion Most of the female injured workers can return to work. The severity of injury, along with some system factors influence the RTW of them.
