Compared with proinflammatory processes in the development of type 2 diabetes,our knowledge on anti-inflammatory cytokines is rather limited.Anti-inflammatory cytokines such as adiponectin,interleukin 1 receptor antagonist(IL-1RA),transforming growth factor-β1 (TGF-β1),growth differentiation factor-15 (GDF-15),omentin,and secreted frizzled-related protein 5 (SFRP5) are strongly associated with increased risk of type 2 diabetes:Adiponectin and omentin levels decreased before type 2 diabetes,in contrast,concentrations of IL-1RA,TGF-β1,GDF-15 are increased.Change of SFRP5 levels in impaired glucose tolerance and type 2 diabetes remains controversial.This paper will summarize and recommend studies that investigated associations between circulating levels of anti-inflammatory cytokines and type 2 diabetes.

BACKGROUND:Osteofascial compartment syndrome is usual y due to application of external fixation for fracture treatment. Vaseline gauze is used to cover and compress the wound. Frequent dressing change induces infection and is harmful to wound drainage and tissue granulation, final y causing prolonged time of hospitalization and bad results. <br> OBJECTIVE:To investigate the clinical efficacy of Ilizarov external fixation combined with vacuum sealing drainage treatment for limb fractures with osteofascial compartment syndrome. <br> METHODS:A total of 32 patients with limb fractures with osteofascial compartment syndrome were randomly divided into two groups. Al patients adopted the same fasciotomy and drug treatment. In treatment group, the fracture was fixed with Ilizarov external fixation and the wound was covered with the vacuum sealing drainage dressing. In control group, the fractures were treated by unilateral external fixation and the wound was covered with the vaseline gauze. The fracture healing, clinical effects, hospitalization duration and costs between two groups were compared. <br> RESULTS AND CONCLUSION:In the treatment group, there were 10 cases of healing wel , 4 cases of muscle contracture and 2 cases of amputation. In the control group, there were 7 cases of healing wel , 6 cases of muscle contracture and 3 cases of amputation. No significant difference in clinical outcome measures was detected between the two groups. Fracture healing rate and costs were higher in the treatment group than in the control group (P<0.05), but hospitalization duration, skin grafts and the incidence of infection were lower in the treatment group than in the control group (P<0.05). Results suggested that on the basis of timely fasciotomy and decompression, Ilizarov external fixation combined with vacuum sealing drainage treatment for limb fractures with osteofascial compartment syndrome has a high limb salvage rate, which can effectively treat fractures, elevate the healing rate of fractures, reduce infection rate and skin grafting rate, shorten hospital stays. However, the hospitalization expense is higher.

BACKGROUND: Thyroid cancer stem cells are essential to the recurrence and metastasis of thyroid carcinoma. Leukemia inhibitory factor receptor (LIFR) shows a downward trend in a variety of malignant tumors, and its overexpression can inhibit the recurrence and metastasis of malignant tumors. OBJECTIVE:To explore the effect of LIFR on the stemness maintenance and lung metastasis of thyroid cancer stem cells in vivo. METHODS: Primary thyroid cancer cells TCLM were isolated from the lung metastases of a metastatic thyroid cancer patient. Serum-free suspension culture was used to form tumor cell balls. Flow cytometry was used to screen CD133+phenotype of metastatic thyroid cancer stem cell subpopulation TCLM-S. The overexpressed recombinant lentiviral plasmid containing LIFR and its negative control containing the empty plasmid were infected into thyroid cancer stem cells TCLM-S at the ratio of virus/cell number=20, and screened with 2.0 mg/L puromycin to construct TCLM-SLIFRand TCLM-Scontrolstem cells which stably expressed LIFR and its control. Real-time quantitative PCR (qRT-PCR) was used to detect the expression of LIFR in TCLM-SLIFRand TCLM-Scontrolstem cells. Flow cytometry was used to detect the percentage of CD133+phenotype cell subsets, western blot assay was used to detect the expression of tumor stemness related factors SOX2, Oct4, Nanog and tumor invasion and metastasis related proteins E-cadherin, matrix metalloproteinase (MMP)-2, MMP-7 in TCLM-SLIFRand TCLM-Scontrol stem cells. TCLM-SLIFRand TCLM-Scontrolstem cells were respectively injected into BALB/c nude mice by tail vein, and the lung metastasis model of thyroid cancer stem cells was constructed. The effect of LIFR overexpression on lung metastasis was observed. RESULTS AND CONCLUSION: Compared with TCLM-Scontrolcells, the expression of LIFR in TCLM-SLIFRcells was significantly increased, the proportion of CD133+phenotype stem cell subsets was significantly decreased, the expression of SOX2, Oct4 and Nanog were significantly decreased, the expression of E-cadherin was significantly increased, and the expression of MMP-2 and MMP-7 was significantly decreased. Moreover, the number of lung metastasis in nude mice given TCLM-SLIFRcells was significantly decreased as compared with those given TCLM-Scontrol cells.To conclude,LIFR overexpression can decrease the stemness and ability of lung metastasis in vivo.
