To study the significance of the levels of plasma inflammatory cytokines (IL-6,IL-8,IL-10 and TNF-?) in patients with acute deep venous thrombosis (DVT) of lower extremity. Methods Forty untreated DVT cases were selected as the subjects in the DVT group, while thirty healthy subjects, whose ages and genders showed no significant difference with the DVT patients, were collected as the control group. The plasma levels of IL-6, IL-8 and TNF-? were detected by radioimmunoassay (RIA), and the plasma level of IL-10 was measured by enzyme-linked immunosorbent assay (ELISA). Correlation analysis was used to investigate the relationships between the levels of different inflammatory cytokines within DVT group. Results The levels of plasma cytokines in the DVT group were all significantly higher than those in control group (P

Objective:To seek the possibility of using internally installed curved mandibular distractor to repair the partial mandibular curved defect.Methods:A curved mandibular defect was sectioned in each of 3 adult dogs.The distractor designed by our own group based on the steel ball conducted force was implanted.After 7 days of latency,the distraction was performed at the rate of 0.5 mm × 2 times per day,followed by 3 months consolidation period.The osteogenesis was evaluated by general observation,X-ray examination and HE staining.Results:No complication was observed after operation and during distraction.The new bone healed well into a curved shape.The X-ray examination revealed that the transport disc moved along with the predesigned rail curve.HE staining clearly showed neo bone formulation zone between the mature trabecular and connective tissue.Conclusion:The internal distractor based on the steel ball conducted force can realize the curved distraction osteogenesis of posteriormandibular.

Objective To explore the advantages and disadvantages between the RapidArc plans and fixed-field IMRT plan (IMRT).Methods Ten cases of cervical cancer,aged 55 (36-70),who were to receive post-operative radiotherapy were selected randomly.Single arc (Arc 1),two arcs (Arc 2),and three arc (Arc 3) RapidArc plans and fixed-field IMRT plan were designed respectively in the Eclipse 8.6 planning system.The designing,treatment time,target area,and dose distribution of organs at risk by these 4 planning techniques were compared.Results The values of average planned treatment time by the Arc 1,Arc 2,and Arc 3 ten cases was 98,155,185,and 46 min,respectively.The values of average treatment time in the Varian IX accelerator were 2.15,3.32,4.48,and 6.95 min,respectively.The average mean doses were (48.99±1.08),(49.40±0.51) ,(49.51±0.62) ,and (48.65±0.92) Gy,respectively.The values of homogeneity index (HI) of target were 1.11±0.07,1.07±0.02,1.06±0.02,and 1.12±0.05,respectively.The values of eonformal index (CI) of target were 0.73±0.13,0.87±0.06,0.87±0.06,and 0.79±0.06,respectively.The doses at rectum,bladder,and small intestine calculated by IMRT plan were the lowest,and the doses at the femoral neck calculated by these 4 plans were similar.Conclusions The RapidArc plan is superior in dose distribution at target,HI,CI,and treatment time to IMRT,but IMRT plan is superior to RapidArc in planned dose calculation time and protection of organs at risk.However,in general,the RapidArc plan is better in clinical application than IMRT plan.

Diabetic vascular disease is a major complication of diabetes, which is characterized by the formation of collateral vessels of serious damage to systemic disease. Substantial evidence have shown that timpaired endothelial progenitor cell function, non-enzymatic glycation end products accumulate, and Wnt signaling pathway dysfunction may be an important mechanism of impaired angiogenesis after the diabeticlimb ischemic. This paper is to make a study of its mechanism, and to provides a new strategy for diabetes therapeutic angiogenesis.

Aim To measure the methylation rate of bone marrow mesenchymal stem cells (BMMSCs) using ultra-performance liquid chromatography-tandem mass spectrometry, and determine the methylation rate in the process of senescence.Methods The DNA extracted from BMMSCs would be digested into individual deoxynucleosides using enzymatic hydrolysis.To quantify the global genomic DNA methylation rate,we developed a method using ultra-performance liquid chromatography-tandem mass spectrometry with multiple reaction monitoring to simultaneously measure the levels of 5-methyl deoxycytidine and deoxyguanosine in digested genomic DNA.Results The DNA methylation rate could be analyzed within two minutes after hydrolyzing 1μg DNA for an hour.The detection limit of DNA methylation rate was 5.00×10-4.The coefficient of variance of the intra-day and inter-day precision was within 7.12×10-2 and 0.119, respectively.With the subculture of BMMSCs, the methylation rate gradually decreased.The methylation rate of stem cells was the lowest in 4~6 generation, and gradually increased with the subculture.Conclusions Using this method, the preliminary data on DNA methylation of BMMSCs in the process of senescence are obtained.The method is simple and convenient for sample preprocessing, and the method is fast and accurate with good sensitivity and repeatability.

Objective:To investigate the expression and the significance of inflammatory cytokine IL-6 through regulating Gli1 in acute pancreatitis.Methods: In this study,C57 mice were randomly divided into three groups:control group,model group,inhibitor group.caerulein intraperitoneal injection induce acute pancreatitis model.Use HE staining and amylase to testify the model successfully.Use RT-qPCR,Western blot to detect the expression of Gli1 in the pancreas,liver,lung,kidney and intestine and ELISA method to detect inflammatory cytokines IL-6.Results: Compared with control group,the expression of Gli1 is higher in model group,then the expression of IL-6 increases in inhibitor group which uses Gant61 to suppress Gli1 compared with model group.Conclusion: Gli1 may involved in the process of the distant tissue injury and repair in acute pancreatitis and through regulate its downstream cytokines like IL-6 to play a protective role in acute pancreatitis.

At 24 h, the expressions of phosphorylated Akt (p-Akt) in 5, 10 and 20 mg/L fluoride groups (0.27 ± 0.01, 0.30 ± 0.03, 0.27 ± 0.03) were higher than that in the control group (0.20 ± 0.02, P < 0.05); at 48 h, the expressions of p-Akt in 5 and 10 mg/L fluoride groups (0.42 ± 0.04, 0.60 ± 0.02) were higher than that in the control group (0.27 ± 0.01, P < 0.05), and that in the 40 mg/L fluoride group (0.18 ± 0.02) was lower than that in the control group ( P < 0.05). The expressions of FoxO1 in 10, 20 and 40 mg/L fluoride groups at 24 h (0.38 ± 0.07, 0.41 ± 0.06, 0.47 ± 0.08) were higher than that in the control group (0.34 ± 0.04, P < 0.05). At 48 h, the expressions of FoxO1 in 5, 10, 20 and 40 mg/L fluoride groups (0.36 ± 0.08, 0.37 ± 0.10, 0.54 ± 0.04, 0.73 ± 0.04) were higher than that in the control group (0.28 ± 0.04, P < 0.05).
