It is now well established that inflammation plays an important role in the development of numerous chronic metabolic diseases including insulin resistance (IR) and type 2 diabetes (T2DM). Skeletal muscle is responsible for 75% of total insulin-dependent glucose uptake; consequently, skeletal muscle IR is considered to be the primary defect of systemic IR development. Our pre- vious study has shown that rutaecarpine (Rut) can benefit blood lipid profile, mitigate inflammation, and improve kidney, liver, pan- creas pathology status of T2DM rats. However, the effects of Rut on inflammatory cytokines in the development of IR-skeletal muscle cells have not been studied. Thus, our objective was to investigate effects of Rut on inflammatory cytokines interleukiri (IL)-1, IL-6 and tumor necrosis factor (TNF)-α in insulin resistant primary skeletal muscle cells (IR-PSMC). Primary cultures of skeletal muscle cells were prepared from 5 neonate SD rats, and the primary rat skeletal muscle cells were identified by cell morphology, effect of ru- taecarpine on cell proliferation by MTT assay. IR-PSMC cells were induced by palmitic acid (PA), the glucose concentration was measured by glucose oxidase and peroxidase (GOD-POD) method. The effects of Rut on inflammatory cytokines IL-1, IL-6 and TNF-α in IR-PSMC cells were tested by enzyme-linked immunosorbent assay (ELISA) kit. The results show that the primary skeletal muscle cells from neonatal rat cultured for 2-4 days, parallel alignment regularly, and cultured for 7 days, cells fused and myotube formed. It was shown that Rut in concentration 0-180. 0 μmol x L(-1) possessed no cytotoxic effect towards cultured primary skeletal muscle cells. However, after 24 h exposure to 0.6 mmol x L(-1) PA, primary skeletal muscle cells were able to induce a state of insulin resistance. The results obtained indicated significant decrease (P < 0.05 to P < 0.001) IL-1, IL-6 and TNF-α production by cultured IR-PSMC cells when incubating 24 hours with Rut, beginning from 20 to 180.0 μmol x L(-1). IL-1, IL-6 and TNF-α in the Rut treated groups were dose-dependently decreased compared with that in the IR-PSMC control group. Our results demonstrated that the Rut promoted glucose consumption and improved insulin resistance possibly through suppression of inflammatory cytokines in the IR-PSMC cells.

OBJECTIVETo explore clinical effects of Ilizarov technique at stage I for repairing tibial post-traumatic osteomyelitis with bone and skin defect.

METHODSFrom June 2010 to December 2013,44 patients with tibial post-traumatic osteomyelitis with bone and skin defect were treated with Ilizarov technique at stage I . Among them, there were 35 males and 9 females aged from 18 to 70 years old with an average of 42.5 years old. Bone defect ranged from 4 to 16 cm, skin defect ranged from 3 cm x 4 cm to 5 cm x 16 cm. The operation was performed debridement thoroughly, removed inflammatory bone section, osteotomy invasively, install circular external fixator by Ilizarow technique; screw nut were rotated at 1 week after operation, and prolonged 0.5 to 1.0 mm everyday. Wound surface, new born callus and bone healing were observed to evaluate clinical effects.

RESULTSAll patients were followed up from 11 to 36 months with an average of 18.5 months. Bone defect after osteotomy was from 6 to 22 cm with an average of 11.5 cm; the time of wound healing time ranged from 21 to 79 d with an average of 38 d; bone defect healing time was from 8 to 15 months with an average of 12.5 months. All patients were cured, no recurrent infection, refracture and shorten of calf deformity were occurred.

CONCLUSIONRepairing tibial post-traumatic osteomyelitis with bone and skin defect by llizarov technique at stage I has advantages of less trauma, low inflammatory recurrence rate, could avoid multiple complex operation, and receive definite curative effect.

OBJECTIVETo determine the effects of nerve growth factor (NGF) on proliferation of hepatic stellate cells (HSCs) and investigate the related molecular mechanism.

METHODSAfter incubating cultured HSCs for 24 h with different concentrations of NGF (100, 200 or 400 ng/mL), the cell proliferation was observed by XTT colorimetric assay and cell cycle was detected by flow cytometry. Morphological changes in response to a 24 h exposure to 100 ng/mL NGF were observed by transmission electron microscopy.

RESULTSNGF significantly inhibited HSC proliferation (P less than 0.05) in a dose-independent manner. The optical densities of the XTT colorimetric assay were 0.66+/-0.03 for 100 ng/mL NGF, 0.69+/-0.03 for 200 ng/mL NGF, and 0.66+/-0.03 for 400 ng/mL NGF, all of which were significantly lower than that of the control group (0.73+/-0.01; P less than 0.05). All concentrations of NGF led to significantly higher numbers of HSCs in the G2 phase (100 ng/mL: 14.83+/-5.41%, 200 ng/mL: 14.73+/-2.50%, and 400 ng/mL: 14.87+/-2.06%), compared to that detected in the control group (7.47+/-4.39%; P less than 0.05). Twenty-four hours of exposure to 100 ng/mL NGF caused morphological changes indicative of apoptosis.

CONCLUSIONNGF inhibits the proliferation of HSCs, possibly by arresting the cells in the G2 phase of the cell cycle. NGF-inhibited cells may also undergo apoptosis.

OBJECTIVETo observe the clinical effects of prunrllae oral solution in treating hyperthyrea.

METHOD56 cases with hyperthyrea were randomized into two groups; group A1 was treated by classic method, B1 was treated by classic method combined with prunrllae oral solution. The size, vessel caliber of thyroidea, volume of blood flow and blood flow rate pre-and post-treatment were measured by color supersonic, meanwhile, 20 normal thyroidea were measured as control group.

RESULTThe size and vessel caliber of thyroidea of the two groups pre-treatment were obviously bigger than those of the control group, the volume of blood flow and blood flow rate were obviously slower than those of the control group (P < 0.001), the sizes of thyroidea of the two groups became smaller, especially the group B1 was more obvious, and there was no significant difference in the size of thyroidea between group B1 and control group.

CONCLUSIONIt is indicated that combined treatment of traditional Chinese medicine (prunrllae oral solution) and western medicine is superior to western medicine in treating hyperthyrea.

OBJECTIVE: To observe the effect of cyclosporine and simulect mono or combination therapy on cardiac allo-transplantation in rats. METHODS: Recipients with allografts were treated with different doses of cyclosporine and/or simulect after cardiac allo-transplantation. Graft survival time was observed; the histopathological examination of graft tissues was performed; and levels of serum IL-2 and IL-4 were determined. RESULTS: Mono or combination therapy with cyclosporine and/or simulect increased the survival of cardiac allografts. With the prolongation of survival time of the grafts, the rejection of grafts was moderated. The serum IL-2 level increased in acute rejected grafts; the serum IL-4 level increased evidently in long survival grafts. CONCLUSION Cyclosporine and simulect have an effect in the prolongation of cardiac allograft survival in rats, and the combination therapy shows an evident synergistic effect.

OBJECTIVE: To explore the role of allo heart and thymus transplantation by intrathymic inoculation of thymocytes. METHODS: Wistar recipients were given intrathymic injection of allo thymocytes (2 x 10(7)) 14 days before the heart and/or thymus transplantation. Graft survival, histopathology, levels and mRNA expressions of IL-2, IL-4 in serum and cardiac-grafts were investigated. RESULTS: Heart transplantation and heart-thymus composite transplantation with the treatment of CysA for 7 or 14 days prolonged graft survival. Heart transplantation and heart-thymus composite transplantation with intrathymic thymocytes injection induced the long-term survival of allo-grafts transiently immunosuppressed with CysA; IL-4 maintained at high levels but IL-2 kept at low levels in grafts in long-term survivals. CONCLUSION Intrathymic inoculation of allo thymoctyes can induce immune tolerance for both cardiac transplantation and heart-thymus combined transplantation in rats. Thymus graft may play a role in the induction and maintenance of central tolerance.

OBJECTIVE: To explore the role of combined heart-thymus transplantation for heart allograft in rats. METHODS: Vascularized heart-thymus combined transplantation was performed with microsurgical technique. Graft survival, histopathology, infiltration of CD4+, CD8+ T cells, level and mRNA expressions of IL-2 and IL-4 in the serum and cardiac grafts were investigated. RESULTS: Heart allograft in the controls had a survival time of (6.0+/-0.76) d. heart-thymus combined transplantation in non-thymectomized rats had a survival time of (6.88+/-0.64)d (P<0.05). Heart-thymus combined transplantation in thymectomized rats led to an evident survival time of (14.13+/-5.82)d (P<0.01) for cardiac graft, which further obtained long term survival after short course of treatment with cyclosporine. Pathologic lesion and infiltration of CD4+ and CD8+ T cells in cardiac grafts showed mitigated in the long term survival group. IL-2 level in the serum and cardiac grafts maintained low level in the long term survival group, whereas IL-4 maintained high level. CONCLUSION Whether thymectomized or not in recipient rats, heart-thymus combined transplantation has a positive effect to protect cardiac graft. Furthermore, in thymectomized rats heart-thymus combined transplantation may lead to evident survival prolongation of the heart grafts, which induces immune tolerance in short course of treatment with cyclosporine.

OBJECTIVE: To observe the effect of FTY720 and ICAM-1 mAb mono and combination therapy in mouse-to-rat cardiac xenotransplantation. METHODS: Cardiac xenotransplantation was performed in abdominal site with micro-surgical technique. Recipients with xenografts were treated with different doses of FTY720 and/or ICAM-1 mAb. Graft survival, histopathology, infiltration of CD4+, and CD8+ T cells and levels of serum IL-2, IFN-gamma, IL-4, and IgM were investigated. RESULTS: Survival time of xenografts was (2.75+/- 0.43)d in the controls, survival of grafts treated with ICAM-1 mAb did not significantly improve. Treatment with large dose FTY720 led to a survival of (4.25+/- 0.71)d (P<0.01). Combination therapy with large dose FTY720 and ICAM-1 mAb achieved a significant prolongation of graft survival with (10.25+/- 2.12)d (P<0.01). Levels of serum IL-2, IFN-gamma and rat-anti-mouse IgM decreased in the combined therapy group. Pathologic lesion and infiltration of T cells in xenografts showed mitigated in the large dose combined therapy group. There was a significant negative correlation between the antibody level and the graft survival time (R=-0.754, P<0.01). CONCLUSION The combined therapy of FTY720 and ICAM-1 mAb can achieve a significant effect in the prolongation of heart xenograft survival and inhibition of xenoantibodies.
