Composite layer with nitrocarbonide and sulfide was made on the surface of CrMoCu alloy cast iron by combined treatment of ion nitrocarburizing and sulphurizing. The composite layer is composed of sulfide layer, nitrocarbonide hypo-surface layer and its diffusing layer, the size of sulfide globular grains distributing equably on the surface is in nano-micron-scale, and the phase structure of the composite layer is composed of FeS, FeS1-x, Fe2C and Fe3N. Under oil lubrication, sulphurized surface shows good scuffing-resistance only under low velocity, and nitrocarburized and sulphurized surface greatly improves the scuffing-resistance and wear-resistance of CrMoCu alloy cast iron, its integrated friction and wear properties are better than those of the plain and sulphurized surfaces under all the velocities.

Objective: PTPRD and PTPRT are phosphatases of the JAK-STAT pathway related to ***, the role and mechanism of PTPRD and PTPRT mutations in multiple cancers remains ***: Clinical data and PTPRD/PTPRT mutation information from 12 cohorts were collected and classified as a discovery cohort and three validation cohorts. The association between PTPRD/PTPRT mutations and immunotherapeutic efficacy was analyzed. Then, the association between PTPRD/PTPRT mutation and immune profiles was analyzed using The Cancer Genome Atlas(TCGA) ***: A total of 2,392 patients across 20 cancer types were included in this study. Our results showed that patients harboring PTPRD/PTPRT mutation, especially co-mutations, had a significantly elevated response rate to immunotherapy in multiple cancers. Patients with PTPRD/PTPRT mutation had a higher objective response rate(ORR)(P=0.002), longer overall survival(OS)(P=0.005) and progression-free survival(PFS)(P=0.038).Importantly, the above findings were further verified in validation cohorts. In addition, we found that the PTPRD/PTPRT co-mutations(co-mut) subgroup exhibited an immune-activated phenotype, the wild-type subgroup tended to have an immune-desert phenotype, and the uni-mutation(uni-mut) subgroup might have an immune-mixed phenotype. Our further analyses suggested that combining programmed cell death ligand 1(PDL1) expression and PTPRD/PTPRT mutation can be used to screen patients who may benefit from ***: PTPRD/PTPRT mutation could serve as a potential predictive biomarker for cancer immunotherapy.

We report a case of a 62-year old woman admitted to our hospital for multiple nodular metastatic liver lesions found by ultrasonography in a regular medical examination. Routine laboratory tests were normal. PET-CT showed multiple bone lesions and nodular liver lesions. Liver biopsy revealed nodular infiltration of multiple myeloma with positive staining of kappa light chain. Further investigation of bone marrow aspiration, immunofixation and immunoelectrophoresis of serum protein, urine test for Bence-Jones protein, 132-microglobulin in serum and urine confirmed the diagnosis. The patient also coinfected with hepatitis C virus （HCV）. With six cycles of chemotherapy with VAD schedule, she achieved complete remission. In this report, a literature review of liver lesions involving multiple myeloma is also provided.

The time series data of silicon content in hot metal were identified to have the chaotic feature because of the positive maximum Lyapunov exponent, and then the time scales to predict future were estimated. Finally a chaotic local-region model was constructed to predict silicon content in hot metal with good performance due to high hitting rate.

Using a volume-limited sample of Main Galaxies from SDSS Data Release 5, we investigate the dependence of galaxy properties on local environment. For each galaxy, a local three-dimensional density is calculated. We find that the galaxy morphological type depends strongly on the local environment; galaxies in dense environments have predominantly early type morphologies. Galaxy colors have only a weak dependence on the environment. This puts an important constraint on the process of galaxy formation.
