Objective:To evaluate the teaching effect of moral education materials implied in scientific research cases in the teaching of "Experimental Traditional Chinese Medicine (TCM)".Methods:The moral education materials implied in scientific research cases of "Experimental TCM" were extracted and skillfully integrated into the teaching of professional knowledge. A questionnaire survey was conducted with questions as "whether it is good to demonstrate the potential humanistic spirit by case teaching, whether this helps improve your interest in science and whether this teaching form affects your study, life and work attitude in the future" "Ten specific items from scientists' moving deeds that touch students and their recognitions" to assess the teaching effect.Results:95.8 percent of students affirmed this teaching form and thought it helped improve their interest in scientific exploration. 87.5 percent of students considered the humanistic spirit would affect their study, life and work in the future. 77.1-89.6 percent of students held a positive attitude to the ten items derived from the scientists' moving stories. Among these items, the percentages of the two items, "the spirit of being able to endure loneliness, work hard to make contributions selflessly without seeking for rewards or reputations" and "having respect forpeople and their scientific research achievements with courage to challenge the authorities of scientific research" are the lowest and highest, respectively.Conclusion:It is good to apply the moral education materials implied in the scientific research cases in the teaching of "Experimental TCM", which basically achieves the teaching goal, but there is still room for improvement.

Experimental Traditional Chinese Medicine is an emerging discipline that plays an important role in cultivating innovative talents of traditional Chinese medicine (TCM). In recent years, with the rapid development of TCM and the new requirements of positioning, and also combined with the college students' cognitive characteristics, we have revised and republished the "Experimental TCM" (Third Edition) textbook, which focuses on introducing knowledge by adopting relevant scientific research cases. This test book was used in the teaching of undergraduates of batch 2013 in the eight-year program in Shanghai University of Traditional Chinese Medicine. After-class questionnaires showed that this teaching mode, guided by scientific research case, is not only helpful for students to develop their quality and ability of adopting modern experimental methods initially in the study and development of TCM, but also able to spread the great achievements of TCM researches. The teaching mode is also conducive to enhancing students' sense of responsibility for the modernization of TCM. Therefore, it is suggested that the course of Experimental TCM should be promoted in the colleges and universities of TCM.

Objective:To explore the role of nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome in non-alcoholic steatohepatitis (NASH).Methods:The liver tissue samples of 24 patients admitted the Second Affiliated Hospital of Fujian Medical University were selected, including 12 NASH samples from liver biopsy and 12 normal liver tissues from the margin of hepatic hemangioma. The expression of NLRP3, apoptosis-associated speck-like protein (ASC), caspase-1, interleukin (IL)-1β and the content of triglyceride (TG) were detected. Wild-type and NLRP3 -/- C57BL/6 mice were fed with normal diet or methionine-choline deficient diet (MCD) for 8 weeks. The wild-type mice were divided into MCC950 NASH, 0.9% sodium chloride (NaCl) NASH, MCC950 and 0.9% NaCl group, 8 mice in each group, and were fed with MCD diet and treated with MCC950, fed with MCD diet and treated with 0.9% NaCl, fed with normal diet and treated with MCC950, and fed with normal diet and treated with 0.9% NaCl respectively for eight weeks. After eight weeks, the pathologic changes of liver tissues were observed with hematoxylin-eosin staining and immunohistochemistry. The levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), free fatty acid (FFA), IL-1β and TG in serum were determined by enzyme linked immunosorbent assay. The expression levels of NLRP3, ASC, caspase-1 and IL-1β in liver tissues were examined by Western blotting and real-time quantitative polymerase chain reaction. Primary Kupffer cells were isolated and cultured from the livers of wild-type and NLRP3 -/- mice and divided into control group and palmitic acid group. The expression levels of related proteins in the supernatant of cells culture were detected by Western blotting. Independent sample t test and one-way ANOVA were used for statistical analysis. Results:The expression levels of NLRP3, ASC, caspase-1, IL-1β and the content of TG of the liver tissues of the NASH patients were all higher than those of healthy control group (all P<0.05). The formation of steatohepatitis in hepatocyte of MCD-fed mice was more obvious than that of nomal diet-fed mice, with more hepatocyte ballooning and inflammatory cell infiltration. The expression of NLRP3, ASC, caspase-1, IL-1β, caspase-1 activity and the content of TG in liver tissue of NASH mice were all higher than those of normal diet-fed group (all P<0.05); and serum levels of ALT, AST, IL-1β, and the content of FAA were all higher than those of normal diet-fed group (all P<0.05). The serum levels of ALT, AST, IL-1β and IL-18 of NLRP3 -/- NASH mice were all lower than those of wild-type NASH mice (all P<0.05). The serum level of ALT, the expression of ASC, caspase-1 and IL-1β in liver tissues, and the degrees of liver fibrosis of wild-type MCC950 NASH group were all lower than those of 0.9% NaCl NASH group (all P<0.05). The expression of NLRP3, ASC, caspase-1, caspase-1 activity, and secretion of IL-1β and IL-18 in Kupffer cells from wild-type mouse treated with palmitic acid were all higher than those of the negative control group (all P<0.05). However, the changes of the above indicators in Kupffer cells from NLRP3 -/- mouse were not affected by palmitic acid treatment. Conclusion:NLRP3 blockade can significantly alleviate the liver injury and fibrosis in NASH mice and prevent the development of NASH.

ObjectiveTo investigate the molecular mechanism by which Si Junzitang in intervening in the development of hepatocellular carcinoma （HCC） by regulating the O-linked β-N-acetylglucosamine modification （O-GlcNAcylation） of nuclear factor kappa-B （NF-κB） p65 in the paracancerous tissues. MethodThe orthotopic liver cancer mouse model was established. Twenty-four C57BL/6 mice were randomly divided into four groups： Normal group， model group， Si Junzitang low-dose group （10 g·kg^-1）， and Si Junzitang high-dose group （25 g·kg^-1）， with 6 mice in each group. The O-GlcNAcylation level and phosphorylation modification level of p65 in the paracancerous tissues were detected using Western blot. The O-GlcNAcylation of p65 was assessed using immunoprecipitation （IP）. The mRNA expression of interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α）， transforming growth factor-β₁ （TGF-β₁）， vascular endothelial growth factor A （VEGFA）， matrix metalloproteinase-2 （MMP-2）， matrix metalloproteinase-9 （MMP-9） in the paracancerous tissues was detected using real-time quantitative polymerase chain reaction （Real-time PCR）. The tumor number， liver weight， locomotor activity， grip strength， and Qi status of the mice were observed and analyzed. ResultCompared with the normal group， the model group showed a significant decrease in O-GlcNAcylation in the paracancerous tissues （P<0.01）， a significant decrease in p65 O-GlcNAcylation （P<0.01）， a significant increase in p65 phosphorylation （P<0.01）， significantly elevated mRNA levels of cytokines IL-6， TNF-α， TGF-β₁， VEGFA， MMP-2， and MMP-9 （P<0.01）， significantly increased liver weight （P<0.01）， significantly declined grip strength， number of grid crossings， and number of vertical stand-ups （P<0.01）， and significantly dwindled Qi status （P<0.01）. Compared with model group， the Si Junzitang low-dose and high-dose groups showed significantly increased levels of O-GlcNAcylation in the paracancerous tissues （P<0.05， P<0.01）， significantly upregulated p65 O-GlcNAcylation levels （P<0.05， P<0.01）， and significantly decreased p65 phosphorylation levels （P<0.01）. In the Si Junzitang low-dose group， the mRNA levels of IL-6， TGF-β₁， and VEGFA significantly decreased （P<0.05， P<0.01）. In the Si Junzitang high-dose group， the mRNA levels of IL-6， TNF-α， TGF-β₁， VEGFA， MMP-2， and MMP-9 significantly decreased （P<0.01）， the number of tumors larger than 3 mm in diameter significantly decreased （P<0.01）， and liver weight significantly decreased （P<0.05）. Additionally， grip strength， number of grid crossings， and number of vertical stand-ups significantly increased （P<0.05， P<0.01）， along with a significant increase in qi status （P<0.01）. ConclusionSi Junzitang can inhibit the progression of orthotopic HCC in mice， which may be achieved by increasing the O-GlcNAcylation level in the paracancerous tissues， enhancing the O-GlcNAcylation of p65， inhibiting the phosphorylation modification of p65， and ultimately suppressing the expression of downstream IL-6， TNF-α， TGF-β₁， VEGFA， MMP-2， and MMP-9.

[Abstract] Objective: To investigate the mechanisms of carnitine palmitoyltransferase 1c (CPT1c) expression to affect the proliferation and apoptosis of human thyroid papillary cancer B-CPAP cells through the AMP-dependent/activated protein kinase (AMPK) pathway in the low glucose and hypoxic conditions. Methods: Firstly,humanthyroidpapillarycarcinomaB-CPAP cells were cultured under normal condition or low glucose and hypoxic condition respectively, followed with the treatment of AMPK inhibitor compound C. Western blotting was used to detect the expressions of AMPK, p-AMPK, peroxisome proliferator-activated receptor α (PPARα) and CPT1c; the proliferation and apoptosis were detected by CCK-8 and Flow cytometry, respectively. Then PPARα-siRNA was synthesized and transfected into B-CPAP cells to knock down PPARα, and then the cells were cultured under normal or low glucose and hypoxic condition respectively.Above indicators were also detected to verify the regulation of PPARα on CPT1c. Finally, the human luciferase reporter plasmid containing CPT1c gene promoter was constructed, and the effect of PPARα on the activity of CPT1c promoter luciferase activity was observed by immunofluorescence. Results: The expressions ofAMPK, p-AMPK, PPARα and CPT1c were significantly increased in B-CPAP cells under low glucose and hypoxia condition (P<0.05 or P<0.01), while cell proliferation and apoptosis rate did not change significantly (P>0.05). After the treatment of AMPK inhibitor compound C, the expressions of p-AMPK, PPARα and CPT1c in low glucose and hypoxia group were significantly decreased (P<0.05 or P<0.01), the inhibitory rate on cell proliferation and apoptosis rate were significantly increased (P<0.05). However, the change range was smaller than that in the normal culture + compound C group (P<0.05).After PPARα knockdown, the expressions ofAMPK, p-AMPK, PPARα and CPT1c in cancer cells cultured under normal conditions were significantly decreased (P<0.05 or P<0.01), and the inhibitory rate on cell proliferation and apoptosis rate were significantly increased (P<0.05). While under low glucose and hypoxia condition, the expression of CPT1c in cells after transfection was significantly decreased (P<0.05), and the inhibition rate on cell proliferation and the apoptosis rate were significantly increased (P<0.05); However, the change range was still lower than that of normal condition group after transfection (P<0.05).After PPARα overexpression, the ratio of fluorescence in the empty vector group was not significantly different from that of the blank group (P>0.05), and the ratio of fluorescence was significantly increased in PPARα over-expression group (P<0.05). Conclusions: AMPK can increase the expression of PPARα to promote the expression of CPT1c in thyroid cancer B-CPAP cells under low glucose and hypoxia conditions, thereby inhibiting cell apoptosis and maintaining cell proliferation ability.
