A research of the cultivation treatments of the commonly used compost fermentations on Volvariella Volvacea production was made in this paper by comparison with the cultivation of raw ingredients. They are zymotechnics of water-logged compost, twice regular zymotechnics and simple twice zymotechnics. The result shows that the cultivation effects of above three are better than that of the cultivation of raw ingredients, among which the simple twice zymotechnics is the best.

Itamin D from the skin and diet is metabolized in the lier to 25-hydroxyitamin D (Figure 1), which is used to determine a patient's itamin D status1,2,3,4; 25-hydroxyitamin D is metabolized in the kidneys by the enzyme 25-hydroxyitamin D-1-hydroxylase (CYP27B1) to its actie form, 1,25-dihydroxyitamin D.1,2,3,4 The renal production of 1,25-dihydroxyitamin D is tightly regulated by plasma parathyroid hormone leels and serum calcium and phosphorus leels.1,2,3,4 Fibroblast growth factor 23, secreted from the bone, causes the sodium–phosphate cotransporter to be internalized by the cells of the kidney and small intestine and also suppresses 1,25-dihydroxyitamin D synthesis.5 The efficiency of the absorption of renal calcium and of intestinal calcium and phosphorus is increased in the presence of 1,25-dihydroxyitamin D (Figure 1).2,3,6 It also induces the expression of the enzyme 25-hydroxyitamin D-24-hydroxylase (CYP24), which catabolizes both 25-hydroxyitamin D and 1,25-dihydroxyitamin D into biologically inactie, water-soluble calcitroic acid.2,3,4

从皮肤和食物来的维生素D在肝中代谢为25-羟基维生素D（图1），被用来决定病人体内维生素D情况的1，2，3，4；25-羟基维生素D在肾中被25-羟基维生素D1羟化酶（CYP27B1）转变为有活性的1，25-二羟基维生素D 。1，2，3，4由肾产生1，25-二羟基维生素D是被血浆甲状旁腺激素和血清钙，磷水平紧密调节。1，2，3，4由骨分泌的成纤维细胞生长因子23使钠磷协同转运蛋白被肾和小肠细胞内化及抑制1，25-二羟维生素D合成。5 在1，25-二羟基维生素D作用下肾和小肠吸收钙及磷的效率增高(图1)。2，3，6 它也包括25-羟四- 24 -羟化酶的表达(CYP24)，且将1，25二羟基维生素D和25羟基维生素D异化成无生物活性，水溶性的维生素D3-23羧酸。2，3，4

When diaryl ketones were treated in DMF promoted by samarium metal with TMSCl as activator, diaryl ketones react with DMF followed by a carbene rearrangement to afford benzoins unexpectedly, with benzils were obtained as byproducts, the formation of which may be explained as a result arising from the auto-oxidation of benzoins. Further investigation found the reaction could also proceed smoothly when I〓 was used as an activator. The reaction could occur as well in SmI〓/THF, though benzoins were obtained in relatively low yields.

发现当有活化剂TMSCl存在时，金属钐能有效的促进二芳酮和DMF的发生反应，偶联后发生卡宾重排，意外地得到苯偶姻类化合物，同时伴随着少量的二芳基二酮副产物生成，我们推测二芳基二酮的生成可能从苯偶姻的自氧化而来；进一步的研究表明，用一定量的I〓活化金属钐，该反应也可以顺利的进行，并且可以得到相对更好的实验结果。
