[Effects of seedling quality on growth of Rehmannia glutinosa and oligosaccharide content].

OBJECTIVE: To study the effect of seedling quality on growth, yield and quality of Rehmannia glutinosa at harvest and build a basis for its GAP. METHOD: The seedling quality of R. glutinosa in main producing regions was surveyed to understand the current status of seedling quality. Field experiments with different varieties and seedling quality were conducted to measure dry matter accumulation with different growth of R. glutinosa and oligosaccharide content, and economic yield at harvest. RESULT: The seedling was randomly selected by farmers in R. glutinosa producing regions. Seedling quality could significantly improve on seedling emergence rate, and promote seedling growth, especially with early stage R. glutinosa, finally increase yield at harvest. At harvest, 63% and 50% of yield with A and B seedling could be improved for variety of 85-5, and 50% and 47% of yield could be increased for variety of Beijing No. 1, compared to the C seeding. CONCLUSION: In cultivation, the seedlings with the diameter > 1.5 cm should be transplanted firstly.

[Effect of early intestinal dripping of jianpi tongli Chinese herbs on serum level IL-2, sIL-2R and IL-12 in patients with gastric cancer after operation].

OBJECTIVE: To explore the regulation and clinical significance of intestinal dripping of Jianpi Tongli (JPTL) Chinese herbs on levels of serum cytokines, such as interleukin-2 (IL-2), soluble interleukin-2 receptor (sIL-2R) and interleukin-12 (IL-12) in treating patients with gastric cancer (GC) at early post-operational stage. METHODS: Sixty patients with GC were randomly divided into two groups, i. e. the studied group (n = 30), treated with JPTL Chinese herbs, and the control group (n = 30) treated with normal saline. The medication was started from the 1st day after operation by intestinal dripping daily, 7 days as one course. Levels of IL-2, sIL-2R and IL-12 were observed before and after operation. RESULTS: Significant difference was seen on the 7th day post-operation between the studied and the control group, mainly in aspects of obvious increase of IL-2 and decrease of sIL-2R (P <0.05), no significant difference in IL-12 was found (P >0.05) though there was certain improvement. Compared with pre-operation of the same group, significant difference was found in the studied group in the increased IL-2 and IL-12 and decreased sIL-2R on the 7th day post-operation, while no significant difference in these indexes was found in the control group (P >0.05), though certain improvement was shown. CONCLUSION: Early intestinal dripping of JPTL Chinese herbs to post-operational patients with GC could improve their immune function, which was of important significance in early preventing the severe complications, improving the prognosis, and elevating the survival rate.
