This paper analyzed the necessity of training of interdisciplinary and innovative think-ing for medical postgraduates and proposed many specific programs for interdisciplinary training con-struction including the building of interdisciplinary curriculum system,comprehensive experiment and communication platform,construction of interdisciplinary innovative tutor team,double or multi-tutorial system,interdisciplinary projects,et al.

Objective To study the inhibitory effect of curcumin on the proliferation,migration and invasion of non-small cell lung cancer cell A549,and to discuss further if it is closely related to the expression of c-Jun N-terminal kinase (JNK) and relative protein p38.Methods A549 cells were cultured by conventional method,and then treated with different concentration of curcumin (10,20,40,80 μmol · L-1).The proliferation,migration and invasion of A549 cells were measured by real-time cellular analysis (RTCA).The expression levels of JNK,p-JNK,p38 and P-p38 were detected by real-time PCR and Western blotting.Results Curcumin showed an antiproliferation effect against A549 cells with IC50 =40 μmol · L-1,and curcumin exhibited obviously inhibitory effect on the migration and invasion of A549 cells.Additionally,compared with control group,curcumin suppressed the expression of JNK and p38 at the gene level,and significantly inhibited the expression of JNK,P-JNK,p38 and p38 (P＜0.05) at the protein level.Conclusion These results demonstrated that curcumin can inhibit the proliferation,migration and invasion of A549 cells via reducing the level of JNK,p38 phosphorylation,and blocking JNK signal transduction pathway.

Objective To investigate the influence of curcumin and its analogue H8 on glucose and lipid metabolism disorder in db/db mice. Methods The type 2 diabetes mouse model (db/db mice) was intragastrically administrated with curcumin and analogue H8 for 8 weeks.The blood biochemical indexes were measured.The expression of PEPCK and G6Pase mRNA was detected by real-time PCR in liver tissues.The expression of PEPCK and G6Pase protein was detected by Western blotting. Results Curcumin analogue H8 reduced blood glucose and lipids in db/db mice (P<0.01) and improved liver function related enzymes significantly.The levels of PEPCK and G6Pase mRNA in db/db mice were significantly decreased (P<0.01) and the expression levels of PEPCK and G6Pase protein were significantly decreased(P<0.01). Conclusion Curcumin analogue H8 improves the glucose and lipid metabolism disorder in db/db mice,and it is related to inhibiting the expression of PEPCK and G6Pase gene and protein.

The incidence rate of drug-induced liver injury (DILI) is increasing year by year, and DILI has become one of the common liver diseases in clinical practice and has attracted the attention of the whole world. It is known that a variety of drugs, including Chinese herbal medicine and dietary supplements, can cause various types of acute or chronic liver injury, and acute liver failure may occur in severe cases, leading to death or liver transplantation. This article elaborates on the global prevalence of DILI and the distribution of common suspected drugs.

With the increasingly wide application of herbal medicines and dietary supplements worldwide， herb-induced liver injury （HILI） has become an important etiology of drug-induced liver injury. Due to the diverse manifestations of HILI， the difficulty in medical history collection， and the lack of specific biomarkers， how to identify suspected patients and make a correct diagnosis has become a major challenge in practice. Causality assessment is commonly used in the diagnosis of HILI， but there is still a lack of prospective cohort studies with a large sample size. In addition， further studies are needed to search for the specific biomarkers for the diagnosis of HILI. The diagnosis and differential diagnosis of HILI are challenging， and currently there is still no universally accepted uniform and standard method for the diagnosis of all-cause HILI.
