[Objective]This study was designed to investigate the effects of 5-aminoimidasole-4-carboxamide ribonucleoside (AICAR)on activity of transcription factor Forkhead O 3a(FOXO3a)and expression of ubiquitin ligase muscle atrophy F-box (MAFbx),and to explore the role of adenosine monophosphate-activated protein kinase(AMPK)on proteolysis pathways in eardiomyocytes.[Methods]The effect of AICAR on activation of AMPK was observed.Cultured neonatal rat cardiomyocytes was treated with AICAR in different concentration.Cultured cardiomyocytes were then divided into three groups:control group,AICAR group,AICAR+Compound C group.Effects of AMPK activation on phosphorylation of FOXO3a and expression of MAFbx in cardiomyocytes were detected using Western blot.[Results]①Compared with control group,activity of AMPK in cultured cardiomyocytes was increased after treatment with 0.25 mmol/L or 0.5 mmol/L AICAR for 6 h(P＜0.05),and the activity of AMPK was further enhanced after treatment with 1.0 mmol/L or 2.0 mmol/L AICAR for 6 h(P＜0.01).②Activation of AMPK by AICAR significantly increased the transcriptional activity of FOXO3a(P＜0.01),and enhanced MAFbx protein expression in cardiomyocytes when comparing with control group(P＜0.01),however,specific AMPK antagonist Compound C markedly reversed these effects induced by AICAR.[Conclusion]AMPK may regulate cardiomyocytes proteolysis by activation of FOXO3a transcription factor,and up-regulation of MAFbx protein expression.

BACKGROUND: Several studies have demonstrated that bone marrow mcscnchymal stem cells (MSCs) can differentiate into osteoblasts after induction of bone morphogenetic protein (BMP).OBJECTIVE: This study was designed to compare the osteogenetic effects between MSCs, bBMP, and fibrin gel alone and their composite.DESIGN: A controlled observation experiment.SETTING: Second People's Hospital of Guangdong Province and Second Hospital Affiliated to Sun Yat-sen University.MATERIALS: This study was performed at the Second Hospital Affiliated to Sun Yat-sen University between January 2004 and June 2006. Healthy New Zealand rabbits were provided by the Laboratory Animal Center, Sun Yat-sen University.METHODS: Bone marrow was taken from the lilac bone. By density gradient centrifugation, autologous MSCs were in vitro cultured and amplified. A composite was made of fibrin gel and bovine bone morphogenetic protein (bBMP). After adding MSCs, another composite was made. Twelve rabbits underwent lumbar L3/4, LA/5, and LS/6 discectomy and interbody fusion via an anterior retroperitoneal approach. Three fusion sites in each animal were randomly assigned into three of four treatments: composite of MSCs and hBMP and fibrin gel (group A), composite of MSCs and fibrin gel (group B), composite of bBMP and fibrin gel (group C) and fibrin gel alone (group D). The interbodies were observed radiologically and histologically 3 months after surgery.MAIN OUTCOME MEASURES: Bone formation in the spinal interveRebral space of rabbits.RESULTS: Twelve weeks after surgery, bone formation was appasenfly greater in the Group A than in the other groups.Histological findings revealed continuous bone formation. The groups B and C showed equivalent radiological and histological changes. Bone formation was intermittent. Group D had fibrous union, but no bone formation. No residual fibrin gel was found in all groups, but a small amount of residual nucleus gelatinosus with a little cartilaginous tissue was visible in the intervertebral disc.X-ray examination results did not reveal vertebral posterior hyperplasia or spinal stenosis. There was significant difference in range of lumbar motion between the group B and the groups C and D (P ＜ 0.05). No pronounced difference in vertebral posterior height loss existed among the groups.CONCLUSION: The composite of MSCs, fibrin gel and bBMP can promote bone regeneration and achieve osseous spinal fusion.

The aim of the present study was to investigate the effects and possible mechanism of tetramethylpyrazine(TMP)on morphine-induced microglia activation and tolerance. The antinociception and morphine tolerance were assessed in mice using hot-water tail flick test. IBA-1(ionized calcium binding adapter molecule 1), the marker of microglia, was detected by immumofluorescence method. The expression of p-p38 MAPK and total p38 MAPK(mitogen-activated protein kinase, MAPK)was analyzed by Western blot; real-time polymerase chain reaction(RT-PCR)was used to detect the expression level of tumor necrosis factor-α(TNF-α)and interleukin-1β(IL-1β). Results showed that TMP(15, 30, 60 mg/kg, ip)inhibited morphine-induced up-regulation of IBA-1, p-p38, TNF-α and IL-1β in a dose-dependent manner, yet with no effect on the expression of total p38 MAPK. In conclusion, TMP significantly inhibited the activation of microglia evoked by morphine via p38 MAPK signaling pathway, thus attenuating morphine antinociception tolerance.

ObjectiveTo compare the differences in color， odor， coumarin content and microbial community composition of Angelicae Dahuricae Radix（ADR） during different drying processes， and to explore the correlation between changes in microbial community composition and changes in quality indexes of ADR. MethodsThe fresh ADR was processed at three drying temperatures（50， 70， 100 ℃） by drying and steaming cutting， semi-fresh cutting and drying， fresh cutting and drying， and sulfur fumigation methods. The color values of samples were extracted by Adobe Photoshop 2022 software and subjected to principal component analysis（PCA）， electronic nose was used to identify the odor information of medicinal powders and subjected to loadings analysis， PCA， and linear discriminant analysis（LDA）， and high performance liquid chromatography（HPLC） was used to determine the contents of five coumarins（bergapten， oxypeucedanin， imperatorin， phellopterin， isoimperatorin）. The samples for microbial detection were taken from fresh dried samples， 50 ℃（dried and steamed cut， sulfur fumigated） samples， and 100 ℃（dried and steamed cut） samples when the water content was 50% and 14%， respectively. And the changes of microbial community composition during processing were determined by high-throughput sequencing method. The relationship between the changes of microbial community composition and the changes of odor， color and active component content of ADR during drying process was analyzed by Pearson correlation analysis. ResultsThe color quantification results showed that an increase in drying temperature led to the decrease of brightness value（L）， and the increases of red-green value（a） and yellow-blue value（b）， and the change of processing method had no obvious effect on the color of medicinal materials. The results of odor quantification showed that W1S， W2S， W5S， W2W and W1W sensor were sensitive to the odor changes of ADR and could be used to distinguish ADR decoction pieces from different processing methods. The results of HPLC showed that the coumarin content of ADR decreased with the increase of drying temperature and the delay of processing time， the optimal processing method was drying and steaming cutting method， and the optimal temperature was 50 ℃. High-throughput sequencing results showed that the dominant bacteria in ADR during processing were Achromobacter， Agrobacterium， Nocardioides， Mycobacterium and Enterobacter， the dominant fungi were Coprinopsis， Meyerozyma and Apiotrichum. The results of correlation analysis showed that the quality indexes of ADR were positively correlated with Agrobacterium， Mycobacterium in bacteria， Candida in fungi， and negatively correlated with Bacillus in bacteria. ConclusionThere are significant differences in the color， odor， coumarin content and microbial community composition of ADR in different drying processes， and the best drying method is drying and steaming cutting at 50 ℃. The relative abundance changes of 9 bacterial genera and 4 fungal genera are closely related to the quality formation of ADR during the drying process.
