OBJECTIVE:To study the apoptosis of human leukemic cells induced by Dihydroartemisinin and its molecular mechanism.METHODS:Human leukemia K562 cells were treated by Dihydroartemisinin.The inhibitory effect on cell proliferation was assayed by MTT.Fluorescence microscopy was applied to observe the presence of apoptosis.The expression of caspase-3 was assayed with reverse transcription-polymerase chain reaction(RT-PCR).Levels of mitochondrial and cytoplasmic cytochrome C were determined using Western blot.RESULTS:After treatment with Dihydroartemisinin for 48 hours,the IC50 values of human leukemia K562 cells were 8? 10-5mol? L-1 detected at a wavelength of 570nm by MTT.Distinct morphology changes of cell apoptosis such as karyopyknosis and conglomeration were observed by Hoechst33342/PI staining.RT-PCR assay showed the expression of Caspase-3.Western-blot detection showed the decrease of mitochondrial cytochrome C concentration but the positive expression of cytoplasmic cytochrome C concentration.CONCLUSION:Dihydroartemisinin could inhibit proliferation and induce apoptosis of human leakemic K562 cells,this may partially attributed to the promotion of the delivery of cyt-c and the activation of caspase-3.

Objective To explore the effect of omni-directional health education on self-management level and blood glucose control in patients with type 2 diabetes mellitus. Methods A total of 100 diabetic patients admitted to the department of neurology of Taizhou Central Hospital from January to December 2016 were randomly divided into an observation group and a control group, 50 cases in each group. All patients were given conventional medication according to their systemic conditions, the control group used conventional nursing care, while the observation group was supplemented with omni-directional health education (including diet control therapy, exercise therapy, blood glucose control, hypoglycemic drug use and observation, foot care, blood glucose self monitoring) on the basis of routine nursing;the course of treatment was 2 weeks in the two groups. The differences in self-management level and the effect of blood glucose control were compared between the two groups. Results On the return visits, the self-management scores were significantly higher in both groups than those before education (the control group was 35.2±9.2 vs. 30.1±5.2, the observation group was 78.6±11.5 vs. 29.8±5.4, all P < 0.05), fasting blood glucose [FBG (mmol/L): the control group was 8.8±2.5 vs. 14.8±2.9, the observation group was 6.1±1.6 vs. 15.1±2.7, both P < 0.05) and 2 hours postprandial blood glucose [2 h PBG (mmol/L): the control group was 12.5±3.4 vs. 22.5±3.8, the observation group was 9.1±2.2 vs. 21.9±3.6) were obviously lower than those before education (all P < 0.05), the degrees of improvement of the observation group were more significant than those of the control group [self management score: 78.6±11.5 vs. 35.2±9.2, FBG (mmol/L): 6.1±1.6 vs. 8.8±2.5, 2 hours PBG (mmol/L): 9.1±2.2 vs. 12.5±3.4, all P < 0.05]. Conclusion Omni-directional health education can improve the self-management level of diabetic patients, and the patient's blood glucose control is relatively better.

Skeletal muscle is the largest tissue in the human body, and it plays a major role in exerting force and maintaining metabolism homeostasis. The role of muscle transcription factors in the regulation of metabolism is not fully understood. MondoA is a glucose-sensing transcription factor that is highly expressed in skeletal muscle. Previous studies suggest that MondoA can influence systemic metabolism homeostasis. However, the function of MondoA in the skeletal muscle remains unclear. We generated muscle-specific MondoA knockout (MAKO) mice and analyzed the skeletal muscle morphology and glycogen content. Along with skeletal muscle from MAKO mice, C2C12 myocytes transfected with small interfering RNA against MondoA were also used to investigate the role and potential mechanism of MondoA in the development and glycogen metabolism of skeletal muscle. MAKO caused muscle fiber atrophy, reduced the proportion of type II fibers compared to type I fibers, and increased the muscle glycogen level. MondoA knockdown inhibited myoblast proliferation, migration, and differentiation by inhibiting the phosphatase and tensin homolog (PTEN)/phosphoinositide 3-kinase (PI3K)/Akt pathway. Further mechanistic experiments revealed that the increased muscle glycogen in MAKO mice was caused by thioredoxin-interacting protein (TXNIP) downregulation, which led to upregulation of glucose transporter 4 (GLUT4), potentially increasing glucose uptake. MondoA appears to mediate mouse myofiber development, and MondoA decreases the muscle glycogen level. The findings indicate the potential function of MondoA in skeletal muscle, linking the glucose-related transcription factor to myogenesis and skeletal myofiber glycogen metabolism.
