Taking G University as an example, through empirical research, this study finds out that the motivation of teachers on medical education research is insufficient; the support and incentive for young and middle-aged teachers to participate in higher education research is insufficient; and universities lack of an efficient higher education research organization system; the social influence of medical research and education is not enough, etc. We call on independent medical universities to further improve the higher education research organization system, change the current situation and increase the support and incentives for young and middle-aged teachers to participate in higher education research, guide teachers to summarize the characteristics of medical education teaching, improve the quality of medical personnel training, and expand the influence of medical education research.

Mitochondrial autophagy is a process to clear dysfunctional mitochondria in the cytoplasm to maintain the integrity of mitochondrial function and cell homeostasis. Mitochondrial autophagy is a complex physiological process， which can maintain the balance of mitochondrial quality and quantity， cell survival under starvation and harsh conditions， and the stability of the intracellular environment. Its molecular mechanism involves a variety of proteins. Many factors can induce mitochondrial autophagy， such as starvation， oxidative stress， hypoxia， depolarization， and other stresses. The accumulation of unfolded proteins can also induce mitochondrial autophagy. In recent years， as a research hotspot， the abnormality of mitochondrial morphology and function is closely related to the occurrence of a variety of diseases. The research on mitochondrial autophagy and the pathogenesis of clinical diseases has attracted more attention， such as tumors， cardiovascular diseases， liver diseases， nervous system diseases， and glucose metabolism disorders. It has been found that regulating mitochondrial autophagy may inspire the treatment of some diseases. Meanwhile， clinical researchers have paid more attention to traditional Chinese medicine （TCM）. As revealed by in-depth research， Chinese medicine has a certain value in regulating mitochondrial autophagy. The research on the pathogenesis of mitochondrial autophagy in related diseases and the intervention of Chinese medicine has found that there are many reports on the regulation of mitochondrial autophagy by Chinese medicine in tumors， cardiovascular diseases， and nervous system diseases. However， the mechanism of mitochondrial autophagy， the balance of mitochondrial autophagy， and the difference in the activation or inhibition of mitochondrial autophagy by Chinese medicine remain unclear. The regulation of mitochondrial autophagy has become a new research target strategy of Chinese medicine in the prevention and treatment of diseases. This paper reviewed the available literature in recent years to provide reference materials for the regulation of mitochondrial autophagy by Chinese medicine and ideas for the follow-up research of Chinese medicine in mitochondrial autophagy.

AIM:This study examined the inhibitory effect of peiminine on the human colonic adenocarcino-ma cell line SW480 and explored the underlying mechanisms.METHODS:SW480 and human normal colonic epithelial CCD-841CoN cells were treated with different concentrations of peiminine and subjected to the CCK-8 assay to select the optimal treatment time and concentration of the compound.SW480 cell migration and invasion were evaluated by the wound-healing and Transwell assays.Cell cycle progression was analyzed by flow cytometry.The expression levels of cell cycle-related proteins were examined by Western blot.SW480 xenograft tumor model was established in nude mice to ex-amine the effect of peiminine on tumor growth and the expression of cell cycle-related proteins in vivo.RESULTS:Peimi-nine(110 mg/L)significantly inhibited the proliferation of SW480 cells compared with the control group(P<0.01),caused cell cycle arrest at G1 phase,and significantly downregulated the expression of cyclin dependent kinase 2(CDK2),CDK4,CDK6,cyclin D1,p-Rb/Rb,E2F1,E2F3,and E2F4(P<0.05).Peiminine inhibited SW480 xenograft tumor growth,prolonged the survival of model mice,and affected the expression of CDK2,CDK4,CDK6,and cyclin D1 in tu-mor tissues.CONCLUSION:Peiminine promotes G1 phase arrest by down-regulating the expression of CDK2,CDK4,CDK6,and cyclin D1,thereby inhibiting the proliferation of SW480 cells.

ObjectiveTo observe the effects of modified Shenqiwan on renal function and fibrosis in diabetic nephropathy mice and explore the underlying mechanism based on the glycogen synthase kinase-3β （GSK-3β）/cyclic adenosine monophosphate （cAMP） response element-binding protein （CREB） signaling pathway. MethodFifty male db/db mice and 10 db/m mice were used in this study. The fifty db/db mice were randomly divided into model group， irbesartan group， and low-， medium-， and high-dose modified Shenqiwan groups. The 10 db/m mice were assigned to the normal group. The mice in the low-， medium-， and high-dose modified Shenqiwan groups were administered with modified Shenqiwan in the dosage form of suspension of Chinese medicinal granules by gavage， those in the irbesartan group were given irbesartan suspension by gavage， and those in the normal and model groups were given distilled water of equal volume by gavage. The intervention lasted for 12 weeks. The blood glucose levels， urine albumin-to-creatinine ratio （UACR）， and the protein expression levels of GSK-3β， CREB， transforming growth factor-β₁ （TGF-β₁）， E-cadherin， Vimentin， fibronectin （FN）， plasminogen activator inhibitor-1 （PAI-1）， and Collagen type Ⅳ （Coll Ⅳ） in the mouse kidneys were recorded before and after treatment. The extent of renal pathological damage was also observed. ResultCompared with the normal group， the model group showed significant increases in blood glucose levels， UACR levels， and the protein expression levels of GSK-3β， TGF-β₁， E-cadherin， Vimentin， FN， PAI-1， and Coll Ⅳ in the kidneys （P<0.05）， decreased protein expression level of CREB （P<0.05）， and severe renal pathological damage. Compared with the model group， the low-， medium-， and high-dose modified Shenqiwan groups and the irbesartan group showed varying degrees of decreases in blood glucose levels， UACR levels， and the protein expression levels of GSK-3β， TGF-β₁， E-cadherin， Vimentin， FN， PAI-1， and Coll Ⅳ in the kidneys （P<0.05）， increased expression level of CREB protein （P<0.05）， and improved renal pathological damage. ConclusionModified Shenqiwan can effectively reduce blood glucose levels， improve renal function， and alleviate fibrosis， and the mechanism of action is related to the inhibition of the GSK-3β/CREB signaling pathway.
