Chinese Journal of Medical Education Research 2015;(1):30-33
In the new economic situation for the new requirements for traditional Chinese medicine innovation talents cultivation, in view of the relevant medical education at home and abroad experience and many years of exploration in our school, we suggest that in the curriculum construction and development of the national institutions of higher learning of Chinese medicine, the experiment teaching of traditional Chinese medicine should be extended by popularizing college students' exploring experiment and innovative experiment and establishing the combined mechanism between the excel-lent students and excellent teachers. We also put emphasis on developing five abilities, which include the ability of structuring own knowledge system, the ability of acquiring useful knowledge and aban-doning other, the ability of logical reasoning and critical thinking skills, the ability of professional in-terest and innovation, and the ability of expressing themselves and communication skills.

[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.

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.

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 To study the expression features of hydrolase genes related to the secretion of thyroid hormone of H22 hepatoma mice with different symptoms in early stage. Methods Firstly, The quantitative diagnosis and syndrome differentiation methods were used in H22 tumor-bearing mice in early stage, the expression profile of Tg and related hydrolase genes in poisonous pathogenic factors syndrome group (PPFS) and qi-deficiency syndromes (QDS) were got, and the major differential expression were selected. Secondly, the experiment was repeated and ELISA were used to detect T3 and T4 in serum, RT-PCR were applied to detect gene transcription level of genes including Tg, Ctsb, Ctsd, Ctsl, Napsa and Tpp1. Results ① Based on gene chip, the expression of Tg, Ctsb, Ctsd, Ctsl, Napsa and Tpp1were decreased in the first batch of experiment, the exactly ratio was Tg(0.77 in PPFS;0.84 in QDS), Ctsb(0.83 in PPFS, 0.91 in QDS), Ctsd(0.79 in PPFS;no notable change in QDS), Ctsl(no notable change in PPFS; 0.65 in QDS), Napsa(0.78 in PPFS; no notable change in QDS), and Tpp1 (0.75 in PPFS; no notable change in QDS), respectively. ② T3 and T4 downregulated in PPFS (the T3 value was 1.519±0.162ng/ml, T4 value was 2.194±0.305mg/dl) and in QDS (the T4 value is 4.366±0.727μg/dl) in early stage (P<0.01), especially in PPFS, which was in accordance with the change of Tg in both batches. ③the same trend happened in the validation of Tg(0.22 in PPFS;0.38 in QDS), Ctsb(0.31 in PPFS;0.55 in QDS), Ctsd(0.36 in PPFS;0.78 in QDS) and Napsa(0.24 in PPFS;0.59 in QDS) ,while ctsl(1.24 in PPFS;2.11 in QDS) and Tpp1 (2.85 in PPFS;0.85 in QDS)werethe opposite;even this, the total trend of the expression in QDS was still higher than that in PPFS. Conclusion All the results showed that the thyroid function of H22 hepatoma mice was inhibited in early stage especially in PPFS.
