Objective To study the expression of LI-cadherin in gastric cancer, gastric stromal tumor, chronic gastritis and intestinal metaplasia. Methods Two hundred and forty four specimens were collected, including normal epithelia (n=28), chronic superficial gastritis (n=30), chronic atrophic gastritis(n=42), intestinal metaplasia (n=58), gastric adenocarcinoma (n=46), paracancerous gastric tissues (n=30), gastric stromal tumor (n=10). The expression of LI-cadherin was detected by S-P immunohischemistry with purified goat polyclonal antibody. Results The expression of LI-cadherin in normal epithelia and chronic gastritis are all negative, the positive rates of LI-cadherin expression in intestinal metaplasia and gastric adenocarcinoma is 83% (48/58) and 65% (30/46) respectively. By Laurien classification, the positive rate of LI-cadherin expression in intestinal type was higher(78% ) than those in the diffuse type (35%) (P<0.05). LI-cadherin was in positive correlation with lymph node metastasis and staging. Paracancerous tissues and gastric stromal tumor did not express LI-cadherin. Conclusions The abnormal expression of LI-cadherin was correlated with intestinal metaplasia and gastric adenocarcinoma. GCs with high LI-cadherin index have more lymph node metastasis. High expression rate of LI-cadherin in gastric cancer tissues may predict poor prognosis.

Objective To discuss the nursing resources allocation status in Xinjiang production and construction corps so that reasonable allocation,utilization and management of the nursing work-forces can be strengthened for ensuring the nursing qualities and adapting to the needs of continuous development of the profession.Methods Information such as the quantity,age,education and the title of technical post of tbe nurses in the year of 2005 was collected and analyzed.Results The results showed shortage of nurses,the average doctor-nurse ratio was 1:1.20;the age structure of the objects investigated was suitable,small at beth ends and big in the middle.while more well educated and well technical post titled nurses were needed.Conclusions The quantity of nurses should be increased properly and the present nursing labors should be made use of scientifically,what's more,the training of the bilingual skill of the nurses should be given according to the multinational region features.
