Objectives: To investigate the effect of the addition of glutamine to WMO solution on the small bowel preservation. Methods:According to preservation solutions, the rats were divided randomly into three groups: University of Wisconsin solution(UW group), WMO solution (WMO group) and WMO solution with the addition of glutamine(WMO G group). And each group was redivided into two subgroups in terms of preservation time of 8 h or 12 h. The intestine was perfused by intubation via abdomial aorta, then the gut was flushed with metronidazole solution(4℃,5%). The proliferation of small intestine was observed through tissue culture. The histology, immunohistochemistry (TUNEL, PCNA) of intestinal mucosa and determination of ATP were used to evaluate the results. Results: Compared with UW group and WMO group, ATP contents of WMO G group were significantly higher, particularly in 12 h subgroup. Apoptosis in WMO G group was slighter than those in UW group and in WMO group. The difference in the two latter was not obviously, although pathological change in UW group was slighter than that in WMO group. The number of positive PCNA cells in WMO G group was more than that in other groups. Conclusions: The addition of glutamine to WMO solution could decrease injury of small bowel induced by cold ischemia, provide energy for the small bowel,and promote the proliferation of small bowel mocosal cell.

Journal of China Medical University 2009;(10):781-782,789
Objective To investigate the expression and localization of S100B protein in the placenta and umbilical cord tissue of the pregnant women at different gestational ages. Methods The placenta and umbilical cord tissues were obtained from 60 healthy pregnant women at different gestational ages:13~27 weeks (a = 20),28~36 weeks (n = 20),37~41 weeks (n = 20). The localization and expres-sion of S100B protein was detected by S-P immunochemical method and Western blotting. Results In the placenta,the S100B protein lo-cated in the trophoblast.myofibroblasts.macrophages and smooth muscle cells. The intensity of immunostaining and protein concentration in-creased with advancing gestation. In the umbilical cord,the S100B protein was found in the smooth muscle cells,myofibmblasts,amnion ep-ithelium, macrophages and monocytes. S100B piotein expression showed no significant difference in the different cells of the umbilical cord. Conclusion S100B protein expression in the placenta and umbilical cord tissues is throughout the gestation and increases with advancing gestation in the placenta.

8.Hyperlactatemia and metabolic acidosis in critically ill patient
Chinese Journal of Clinical Nutrition 2011;19(3):183-187
The relationship between hyperlactatemia and metabolic acidosis, which may involve shock resuscitation,homoiostasis, and nutritional support, remains a hot topic. On one hand, increased production of lac-tate due to anaerobic glycolysis during tissue hypoperfusion can aggravate metabolic acidosis; on the other hand,the utilization of lactate at organ and cell levels may lower blood lactate level, and thus alleviate metabolic acidosis.The ultimate blood lactate level depends on the balance of these two action mechanisms.
