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.

AIM: To study the anti-cancer effects of octreotide on the proliferation of liver cancer cells. METHODS: The liver cancer cells SMMC-7721 were cultured in RPMI-1640 media with 10% fetal bovine serum, 100 U?ml -1 penicillin and streptomycin. 10 -5, 10 -4, 10 -3 and 10 -2 g?L -1 of octreotide were added and MTT colorimetric assay were used to detect the growth inhibition rate. DNA staining and cell cycle analysis were done at 0, 6, 12, 24 and 36 hours after medication when the concentration of octreotide was 10 -3 g?L -1. RESULTS: MTT colorimetric tests showed that octreotide suppressed the growth of liver cancer cells. 48 hours after medication, the cell growth inhibition rate was 9.33%, 12.70%, 19.70% and 20.93% when the octreotide concentration was 10 -5, 10 -4, 10 -3 and 10 -2 g?L -1 separately. Cell cycle analysis showed that the percentage of G 0-G 1 phase cells increased and the percentage of G 2-M phase cells decreased. CONCLUSION: Octreotide inhibits the cultured liver cancer cells proliferation in vitro, its mechanisms may be related to preventing the G 0-G 1 phase cells from going into G 2-M phase.

[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.

Objective To study the relationship between overlapping symptoms (OS) and psycho- mental factors in patients with functional dyspepsia (FD) in order to understand the possible mechanisms of OS.Methods One hundred and three FD patients diagnosed by Rome Ⅲ criteria were divided into with or without OS groups by Rome Modular Questionnaire.The emotional status,sleep status,anxiety and depression status were evaluated by Zung Anxiety and Depression Scale and quality of life was eveluated by SF-36 questionnaire.The results were compared between the two groups.Results The proportion of the patients with and without OS accounted for 62.5% and 37.5%,respectively.The patients with OS had a worse emotional status ("bad%" and "very bad%" being 39.1% and 20.2% vs.15.4% and 12.8%,P=0.018) and a worse sleep status (45.3% and 11.0% vs.19.1% and 7.7%,p=0.018)than those without OS.The proportion of the patients with anxiety (49 % ) and depression (68 % ) status in OS group was significantly higher than that in without OS group (19% and 44%,respectively,P<0.05). The quality of life of the patients with OS was worse in the dimensions of psychological health (47.9), vitality (47.1) and mental component score (32.8)than those in without OS group (57.8,57.0,37.0, respectively,P<0.05).Conclusions The psycho-mental factors are associated with overlapping symptoms in patients with FD,which suggests that abnormal psycho-mental factors may be involved in the mechanisms underlying overlapping gastrointestinal symptoms in FD.
