Objective:To explore the effect of the solution-focused brief group counseling on relieving procrastination of graduate students.Methods:Totally 33 graduate students with procrastination [the score of Pure Procrastination Scale (PPS) was more than or equal to 3.5] were selected through the Internct.They were randomly divided into two groups,17 in the ordinary counseling group (ordinary group) and 16 in the solution-focused counseling group (SF group).Samples in the SF group were given the solution-focused brief group counseling,while the ordinary group was given ordinary group counseling.The General Self-efficacy Scale (GSES),Self-control Scale (SCS) and Pure Procrastination Scale (PPS) were used to get the outcome of graduate students at baseline,the time after the group counseling (1 week follow-up,1 month follow-up).Results:The interactive effect between group and time of SCS,PPS were statistically significant (Ps ＜0.01).Separate analyses showed that there was no significant difference between two groups in all variables at baseline (Ps ＞0.05).At the end of the group counseling,the SCS scores were higher in the SF group than in the Ordinary group,and the PPS scores were lower in the SF group than in the Ordinary group.Conclusion:It suggests that solution-focused brief group counseling could improve selfcontrol and relieve procrastination.

Objective Effect of hawthorn and melanoidins on the in-vitro growth of Bifidobacterium and E.coli. Methods According to methods of the Chinese pharmacopoeia (2015),the charred hawthorn was prepared. The melanoidins in charred hawthorn were separated and purified by the macroporous resin extraction process. Ultraviolet spectrophotometry was used to detect melanoidins. The gas chromatography was used to detect the effects of hawthorn, charred hawthorn and melanoidins on the content of the acetic acid in Bifidobacterium and E.coli during growth, stable and decay period. Results In the early stage, the effects of hawthorn and charred hawthorn on bacteria were greater than melanoidins. In the middle and late stage, melanoidins inhibited the growth and metabolism of E.coli by changing the generation of acetic acid, and contributed to that of Bifidobacterium and also promoted the generation of acetic acid and regulate the intestinal flora. Conclusion Hawthorn, charred hawthorn and melanoidins all promote digestion by promoting the growth and metabolism of intestinal flora. Among them, charred hawthorn has a better effect on intestinal flora.
