[Objective]To analyze the prognostic factors of resectable acral melanoma patients ,then develop a novel prognostic model and examined its prognostic value.[Methods]The study retrospectively analyzed clinicopathological characteristics and inflam?matory markers of 232 acral melanoma patients who underwent radical surgical resection between 2000 and 2011 at the Sun Yat-sen University Cancer Center. Kaplan-Meier curves were plotted to estimate overall survival. Significantly predictive factors were identified by multivariate Cox regression analyses and a prognostic model based on these variables was constructed to predict survival.[Results]Cox regression analysis revealed that age,lactic dehydrogenase(LDH),stage,globulin(GLB)and C-reactive protein (CRP)were independently related to survival. After computing these scores ,patients were classified into three risk groups. The new prognostic model identified three categories of patients with different prognoses(P<0.001)and significantly stratify patient prognosis in different tumor stages. The 5-year survival rate was 42.9%,25.7%,and 3.7%in groups 1,2,and 3,respectively. The AUC of new prognostic model is 0.664(95%CI:0.599-0.724).[Conclusion]Age,LDH,stage,GLB and CRP were independently related to survival in our study population,and the prognostic model is useful to stratify patients into different risk groups and it is a useful complement to AJCC staging for Asian patients with acral melanoma.

Objective To evaluate the therapeutic effect of oral and external application of Chinese medicine combined with Ilizarov external fixator and the accordion technique for severe chronic osteomyelitis of the tibia.Methods A total of 78 patients with severe chronic osteomyelitis of the tibia were randomized into a routine treatment group and a combined treatment group, 39 in each group. All the patients in the two groups received external fixation by use of Ilizarov external fixator and the accordion technique. All the patients in the combined treatment group received oralGuyu decoction. The patients who had large wound received vacuum-sealing drainage in the routine treatment group, and vacuum-sealing drainage combined with external application ofShengji-Yuhong plaster in the combined treatment group. All the patients were treated for 8 weeks and followed up for 2 years. The time to wound healing and fracture healing, and the drainage time were compared between the two groups. Functional and radiologic findings were evaluated according to Paley's criteria. The functions of the knee joint and ankle joint were evaluated using the Hospital for Special Surgery (HSS) knee score and the scoring system of Baird and Jackson, respectively.Results The time to wound healing (17.33 ± 6.21 dvs. 22.27 ± 8.12 d;t=3.018,P=0.004) and the time to fracture healing (32.25 ± 6.02 weeks vs. 36.37 ± 7.75 weeks;t=2.623,P=0.011), and the drainage time (17.01 ± 4.66 dvs. 21.51 ± 5.23 d;t=4.012, P<0.001) in the combined treatment group were significantly shorter than those in the routine treatment group. According to Paley's criteria, the patients who achieved a score of excellent or good for fracture healing (84.6%vs. 53.8%;χ2=7.282,P=0.007) and function (92.3%vs. 66.7%;χ2=6.369,P=0.012) in the combined treatment group were significantly more than those in the routine treatment group. The scores of the HSS knee score (84.56 ± 7.42vs. 78.81 ± 5.33;t=3.391,P=0.002) and the scoring system of Baird and Jackson (85.01 ± 8.21vs. 79.21 ± 6.78;t=3.402,P=0.024) in the combined treatment group were significantly higher than those in the routine treatment group.Conclusion OralGuyu decoction and external application ofShengji-Yuhong plaster combined with Ilizarov external fixator and the accordion technique can promote recovery of the joint function, fracture healing and wound healing.

Objective To explore the protective effect in a model of nicotinamide riboside(NR)against carbonyl cyanide m-chlorophenylhydrazone(CCCP)-induced oxidative stress in R28 cells.Methods 4 μmol/L CCCP was used to induce oxidative stress in R28 cells,and 400 nmol/L NR was used to intervene.The cell viability was quantified by CCK-8 assay.The apoptosis was detected by Annexin-V/PI double staining and flow cytometry.Western blotting was used to examine the levels of Cytochrome C,Caspase-3,and Caspase-9 to evaluate the apoptosis.Tetramethylrhodamine ethyl ester was used to detect the mitochondrial membrane potential(MMP),MitoSOX was used to detect the mitochondrial reactive oxygen species(mtROS)levels,and adenosine triphosphate(ATP)assay kit was used to assess ATP generation ability to evaluate mitochondrial function.Results After CCCP treatment of R28 cells,the cell viability decreased,the apoptotic protein levels and apoptosis rates increased,the MMP decreased,and the mtROS generation increased(P<0.05).After NR pretreatment,the cell viability increased,the apoptotic protein levels and apoptosis rates decreased,the MMP increased,and the mtROS generation decreased(P<0.05).Conclusion:NR enhances the cell viability,reduces the expression of apoptotic proteins,and ultimately reduces the apoptosis of retinal ganglion cell by inhibiting oxidative stress response and protecting mitochondrial function.

Zinc levels are high in pancreatic β-cells, and zinc is involved in the synthesis, processing and secretion of insulin in these cells. However, precisely how cellular zinc homeostasis is regulated in pancreatic β-cells is poorly understood. By screening the expression of 14 Slc39a metal importer family member genes, we found that the zinc transporter Slc39a5 is significantly down-regulated in pancreatic β-cells in diabetic db/db mice, obese ob/ob mice and high-fat diet-fed mice. Moreover, β-cell-specific Slc39a5 knockout mice have impaired insulin secretion. In addition, Slc39a5-deficient pancreatic islets have reduced glucose tolerance accompanied by reduced expression of Pgc-1α and its downstream target gene Glut2. The down-regulation of Glut2 in Slc39a5-deficient islets was rescued using agonists of Sirt1, Pgc-1α and Ppar-γ. At the mechanistic level, we found that Slc39a5-mediated zinc influx induces Glut2 expression via Sirt1-mediated Pgc-1α activation. These findings suggest that Slc39a5 may serve as a possible therapeutic target for diabetes-related conditions.
