Aim To study the effect of forskolin on cor-ticosterone secretion in mouse adrenocortical tumor cells. Methods Y1 cells were treated with 1μmol· L-1 or 10μmol·L-1 forskolin for 15 min to 24 h. Y1 cells growth morphology was observed, cell culture su-pernatants were collected and corticosterone was tested by ELISA kit. The cells total RNA was extracted using TRIzol kit and was reversely transcribed to obtain the cDNA, then was amplificated by real time quantitative PCR. The cells were lysed with RIPA lysis buffer and protein expressions were carried out by Western blot. Results Y1 cells morphology changed from flat adher-ent to shrink and spherical growth after 1μmol · L-1 forskolin treatment for 3 h. Compared with the control group, corticosterone levels were increased significantly by 1μmol · L-1 forskolin treatment for 24 h ( P <0. 01), then, forskolin significantly enhanced steroid ogenic acute regulatory protein ( Star) mRNA and pro-tein expression ( P <0. 01 ) , moreover, the steroido-genic enzymes such as Cyp11 a1 and Cyp11 b1 mRNA expressions were also up-regulated significantly by fors-kolin ( P <0. 01 ) . Additionally, Star mRNA expres-sion was increased significantly in a time-dependent re-sponse after 10μmol·L-1 forskolin treatment from 1 h to 12 h (P<0. 01). Furthermore, Nr4a1 and Nr4a2 mRNA expressions were up-regulated significantly after 10μmol · L-1 forskolin treatment from 15 min and reached the top at 1 h ( P<0. 01 ) . However, forsko-lin showed no effect on Mc2 r and Nr5 a1 mRNA expres-sions. Conclusion Y1 mouse adrenocortical tumor cells have a strong response to adenylate cyclase ago-nists, then, forskolin can be used to glucocorticoid se-cretion inducer reagent.

[Objective] To investigate and discuss if there are special syndromes,same disease but different syndromes and same syndrome but different diseases in the different gastric ulcer rat models.[Methods] Based on reports,we select fourmethods-stress,antifani,apoplon,and alcohol to make gastric ulcer model simultaneously,and set up the normal and control groups.Then we use the standardized and quantified four diagnostics and differentiation methods for mice,which are established to examine and appraise the above models in an objective,dynamic and quantified way.[Result] First,different mice models have different syndromes,such as in the water immersion model,damage to Qi blood Yin and Yang was slight and recovered quickly.The anti-fani model,with typical syndromes of cold in the stomach,is a compound model of Qi,blood,Yin and Yang deficiency;second,there exists syndrome evolution in the disease diversity stage in the same rat;moreover,significant syndrome difference exists for the same disease in different rat.For example,on the second day after the alcohol was given to the rats,there was Yin deficiency,or abundance of Qi,or deficiency in both Yin and Yang to the different individual.Thirdly,as for same syndrome but different disease,similar syndromes appear on the same stage in different diseases,as well as the similar syndrome appear on the different stage in different diseases.For instance,the anti-fani model and the apoplon model have similar syndromes of cold in the stomach,Qi deficiency,Yin and Yang deficiency.[Conclusion] There exist respective syndromes in different gastric ulcer mice models.We can infer that to put into practice"treating the same disease with different methods"and"treating different diseases with same method"will help improve the curative effect.

It is a brief review of our research on the role of metallothioneins (MTs) in the occurrence and development of hepatocellular carcinoma (Hcc) in more than a decade,and the mechanism of prevention and treatment for Hcc in the field of TCM.It was found that MTs were required for the malignant proliferation of Hcc cells and their expressions significantly increased under different levels of stress.MTs may exert their effects on promoting proliferation via increasing ribosomal protein gene or other gene expressions.The over-expressions of MTs directly altered the balance of ions in the cell nucleus,and interacted on the genes promoting malignant proliferation.Hepatotoxicity and hepatic damage caused by DEN were reduced and relieved to different extents by the representative formula or constitute,which under the common therapeutic principle,by which MTs expressions were down-regulated as well.In conclusion,both effects above are important in the liver protection,inhibition of hyperplasia and carcinogenesis.

Objective On the issues of students' lack of representative collection of literature in problem-based learning (PBL) courses of TCM integrated experiments, to try to explore the litera-ture studying and reading route. Method Totally 41 full-time seven-year medical postgraduate of Shanghai University of TCM were randomly divided into two PBL classes, that are class A (n=20) an class B (n=21). Three PBL units were carried out in class A and class B by parallel; the oriented literatures were provided by tutors alternately, and after PBL courses, the appraisal were performed by students and tutors independently, using SPSS 19.0 for data analysis, t test to compare between groups. Results First, the students' assessment indicated that the 75% (15/20) students of Class A and 80.9%(17/21) students of Class B of class gave a good evaluation of the teaching method. Two classes had more than 80% of the students who thought the literature teachers provided was representative and instructive and over 60.0% students of both classes thought that the teaching measures could improve the classroom efficiency and after-school learning efficiency. The tutors' assessment revealed that there were no significantly differences between the quantity of these references in PPT (P>0.05) made by students in A class and B class in PBL unit 2 and unit 3; but an increasing trend did exist after the leading literatures were provided and the discussions among students were focusing and rele-vant and the teaching goal was achieved . Conclusion The route of providing a small amount of oriented literatures by tutor is positive in PBL courses of TCM integrated experiments, while the design of teaching experiment, the specific way of providing oriented literatures, the quantity and quality of literatures, and even the internal connection between them, all needs further optimization.
