Résumé
In order to study the effect and its potential mechanism of metformin combined with cisplatin treatment on human osteosarcoma MG-63 cells, MG-63 cells were treated with metformin and cisplatin and the cell proliferation and apoptosis were detected using CCK8 and flow cytometry; Cell clone formation experiment was performed to detect clone formation rate in each group; Trans well experiment was used to detect the migration and invasion ability of osteosarcoma MG-63 cells, and qPCR and Western blot were used to detect the expression of RNA and protein of apoptosis-related genes. The results showed that metformin combined with cisplatin inhibited the proliferation of human osteosarcoma MG-63 cells and promoted their apoptosis significantly (P < 0. 01); Metformin combined with cisplatin inhibited the clone formation (P < 0. 01), and the migration and invasion of human osteosarcoma MG-63 cells (P < 0. 01); Furthermore, metformin combined with cisplatin down-regulated the expression of apoptosis-related genes MCl ̄1and XIAP (P <0. 01), but up-regulated the expression of apoptosis-related genes CASPASE ̄3 and Cyto C (P <0. 01) and migration and invasion related genes MMP ̄2 and MMP ̄9 (P <0. 01). Our study indicated that metformin combined with cisplatin inhibited proliferation, promoted cell apoptosis through MCl ̄1 and XIAP, and inhibited cell migration and invasion by regulating the MMP ̄2 and MMP ̄9 pathways in human osteosarcoma MG-63 cells.

OBJECTIVE@#To observe the effects of electroacupuncture (EA) pretreatment on the cardiac ejection fraction (EF), the number of macrophages in spleen and heart, and the expression of nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) and interleukin-1β (IL-1β) in myocardium in mice with acute myocardial ischemia, and to explore the possible mechanism of EA pretreatment on promoting myocardial protection.@*METHODS@#A total of 30 male C57BL/6J mice were randomly divided into a control group, a model group and an EA pretreatment group, 10 rats in each group. The acute myocardial ischemia model was established by ligating the left anterior descending branch of the coronary artery in the model group and EA pretreatment group, while threading but no ligating at left anterior descending branch of the coronary artery was applied in the control group. In the EA pretreatment group, mice were intervented with EA at bilateral "Neiguan" (PC 6), disperse-dense wave, frequency of 2 Hz/15 Hz, intensity of 2 mA; each EA treatment last for 20 min, once a day, and 3-day treatment was given before model establishment. The EF value was evaluated by ultrasonic cardiogram; the number of macrophages in spleen and heart was measured by flow cytometry; the expression level of NLRP3 and IL-1β in myocardium was measured by Western blot.@*RESULTS@#Compared with the control group, the EF value was decreased in the model group (<0.001), the number of macrophages in the heart and spleen was increased (<0.001), and the expression level of NLRP3 and IL-1β in the myocardium was increased (<0.001, <0.01). Compared with the model group, the EF value was increased in the EA pretreatment group (<0.01), the number of macrophages in the heart and spleen was decreased (<0.01), and the expression level of NLRP3 and IL-1β in the myocardium was decreased (<0.01, <0.05).@*CONCLUSION@#EA pretreatment could reduce the number of macrophages in spleen and heart, down-regulate the expression of NLRP3 and IL-1β in myocardial tissue in mice with acute myocardial ischemia, which could relieve the local inflammatory response and achieve the myocardial protective effect.

OBJECTIVE@#To observe the effects of moxibustion at "Guanyuan" (CV 4) and "Sanyinjiao" (SP 6) on bone morphology, metabolism and ERα of bone marrow mesenchymal stem cells (MSCs) in the ovariectomized rats and explore the underlying mechanism of moxibustion at Guanyuan (CV 4) and Sanyinjiao (SP 6) on the regulation of bone metabolism.@*METHODS@#A total of 60 SD rats were randomized into a normal group (20 rats) and an ovariectomy group (40 rats). In the normal group, no any treatment was provided. In the ovariectomy group, the classical ovariectomy was adopted to set up the osteoporosis model. In the 13th week after ovariectomy, 10 rats were collected from each of the normal group and the ovariectomy group for model identification. After model identification, the ovariectomy group was subdivided into a model group, an estradiol group and a moxibustion group, 10 rats in each one. In the normal group and the model group, the gavage was provided with 2 mL 0.9% sodium chloride solution, once a day. In the estradiol group, the gavage was provided with 17β-estradiol 100 μg/(kg•d), once a day. In the moxibustion group, moxibustion was applied at "Guanyuan" (CV 4) and "Sanyinjiao" (SP 6), 15 min at each acupoint, once a day. The 6 treatments were as one course, with 1 day of interval, 12 courses were required. After 12-week intervention, the dual-energy X-ray was adopted to determine the bone mineral density (BMD) and bone mineral content of the whole body in living condition. After sacrificed, HE staining was adopted to observe femur structure, the enzyme-linked immunosorbent assay was to determine the absorbance of estradiol (E) and alkaline phosphatase (ALP) in serum and the real-time quantitative PCR method was to determine the mRNA expressions of ERα of MSCs in tibia and femur.@*RESULTS@#Compared with the model group, BMD was increased obviously in the pelvis and spine in the moxibustion group and the estradiol group (0.05). Compared with the model group, the bone trabeculas were stronger and well connected in the moxibustion group, indicated by HE staining. Compared with the model group, the concentrations of E in serum were increased obviously in the estradiol group and the moxibusiton group (both <0.01), and ALP concentrations reduced obviously in the estradiol group and the moxibustion group (both <0.001), the mRNA expressions of ERα in MSCs increased in the estradiol group and the moxibustion group (both <0.001).@*CONCLUSION@#Moxibustion at "Guanyuan" (CV 4) and "Sanyinjiao" (SP 6) effectively increases BMD and bone strength in the ovariectomized rats and the mechanism may be related to the improvement of serum E concentration, the decrease of serum ALP concentration and the up-regulation of mRNA expression of ERα in MSCs.

Résumé
Since neurotrophic factor is easy to degrade and aggregate, it usually has a short half-life in vitro. To overcome this shortage, neurotrophic factor has been combined with the silk fibroin (SF) membrane to realize less degradation, optimal loading efficiency, sustained release, and good adsorption. By optimizing its binding conditions, main parameters were investigated and its optimal loading efficiency was obtained. bFGF was combined to SF membrane by layer by layer (LbL) static adsorption technique. The natural and nontoxic chondroitin sulfate (CS) was used as a crosslinking agent. Optimization was carried out in three aspects: the concentration of bFGF, the concentration of CS, and the reaction time. This experiment provides a better environment for the growth of cells and offers a new kind material of absorbing neurotrophic factor to meet increasing demand for biological materials.
