Let（Ω , E, P） be a probability space, F a sub-σ-algebra of E, L^p（E）（1 p ＋∞） the classical function space and LF^p（E） the L^0（F）-module generated by L^p（E）, which can be made into a random normed module in a natural way. Up to the present time, there are three kinds of conditional risk measures, whose model spaces are L^∞（E）, L^p（E）（1 p ＋∞） and LF^p（E）（1 p ＋∞） respectively, and a conditional convex dual representation theorem has been established for each kind. The purpose of this paper is to study the relations among the three kinds of conditional risk measures together with their representation theorems. We first establish the relation between L^p（E） and LF^p（E）, namely LF^p（E） = Hcc（L^p（E））, which shows that LF^p（E）is exactly the countable concatenation hull of L^p（E）. Based on the precise relation, we then prove that every L^0（F）-convex L^p（E）-conditional risk measure（1 p ＋∞） can be uniquely extended to an L^0（F）-convex LF^p（E）-conditional risk measure and that the dual representation theorem of the former can also be regarded as a special case of that of the latter, which shows that the study of L^p-conditional risk measures can be incorporated into that of LF^p（E）-conditional risk measures. In particular, in the process we find that combining the countable concatenation hull of a set and the local property of conditional risk measures is a very useful analytic skill that may considerably simplify and improve the study of L^0-convex conditional risk measures.

To investigate the histological change and the expressions of epidermal growth factor (EGF) and epidermal growth factor receptor (EGFR) in atrophic gastric mucosa in rats so as to appraise the effect of these regulators on the formation of atrophic gastritis, to study the expressions of EGF and EGFR in rats with chronic atrophic gastritis (CAG) after the irradiation of He-Ne laser, and to investigate the relations of He-Ne laser and precancerous lesion or apoptosis. The rats were divided into normal group, model group and laser group. The models of CAG rats were established with enema which was the mixed liquor consisted of sodium salicylate and alcohol, combined with irregular fasting and compulsive sporting as pathogenic factors. He-Ne laser(3.36 J/cm2 ) was used to irradiate CAG rats, once a day for 7 min, 20 days as a course of treatment; the expressions of EGF and EGFR were detected with immunohistochemical method. During the process of antral atrophy, the expressions of EGF and EGFR increased, they were higher in model group than those in normal group (P<0.05). After the irradiation of He-Ne laser, the expressions of EGF and EGFR were obviously lower than those in model group (P<0.05). We draw the conclusion as follows: gastric mucosa of model rat is in a hyper-proliferation status, with high protein expressions of apoptosis suppressor EGF and EGFR. CAG has some correlation with the imbalance between cell proliferation and apoptosis. He-Ne laser (3.36 J/cm2 ) can reduce the expressions of EGF and EGFR, which is an effective physiostimulator to stimulate the gastric mucosa of rat. The appropriate secretions of EGF and EGFR are propitious to the repair and regeneration for the gastric mucosa tissues, thus preventing CAG to canceration.
