The invention is directed to a method of monitoring or detecting treatment-resistant clones in a patient being treated for a lymphoid or myeloid neoplasm from which patient-specific correlating clonotypes have been identified. In some embodiments, such method includes the steps of obtaining a sample from the patient comprising T-cells and/or B-cells; amplifying molecules of nucleic acid from the T-cells and/or B-cells of the sample, the molecules of nucleic acid comprising recombined DNA sequences from T-cell receptor genes or immunoglobulin genes; sequencing the amplified molecules of nucleic acid to form a clonotype profile; determining from the clonotype profile a level of each correlating clonotype and clonotypes clonally evolved therefrom; and correlating a presence of a treatment-resistant clone of the neoplasm with a change in relative levels of the correlating clonotypes and clonotypes clonally evolved therefrom. In part, the invention permits one to distinguish between cases where treatment is effective but insufficiently intense and cases where a cancer clone arises that is resistant to a current treatment approach.

A high-temperature annealing treatment resistant single-component chromium-free aqueous silicon steel sheet insulated masking liquid is characterized in that the main ingredients include organic resin, inorganic water dispersion liquid, curing agent and other additives. The weight ratio of the components is as follows: 100 parts of the organic resin, 100-400 parts of inorganic matter, 5-30 parts of the curing agent, 1-20 parts of additive surface active agent and the rest of water, and the solid content of the masking liquid is 30-50 percent. The masking liquid does not contain toxic organic solvent and chromate, has excellent performances of coating appearance, adhesion, salt spray resistance, insulativity and the like, and can still keep good insulativity after going through high-temperature stress annealing process. After a high-temperature annealing experiment (nitrogen atmosphere, 750 DEG C/2h), the interface resistance retention value is more than 70 percent. The curing speed of the masking liquid is fast, the curing is thorough, and the surface of the membranous layer does not turn sticky for a long time of placement after curing. The masking liquid is in the form of single component, has convenient use and can be stored for long time.

The present invention relates to methods for prognosis, diagnosis, and treatment of malignant tumors that were treatment resistant.

The invention provides a high temperature heat treatment resistant DM code label and a manufacturing method thereof. The manufacturing method comprises the following steps: coating a uniform, compact and tightly-bound golden yellow ZrN coating on the surface of TC4 titanium alloy as a label, controlling the thickness of the ZrN coating in a range of 1 um to 10 um, and engraving a DM code on the ZrN coating with a fiber laser through a back engraving technique so as to form the high temperature heat treatment resistant DM code label. The DM code is in accord with the DM code in a part, then the label is placed on the part, a heat treatment is carried out on the label and the part, and the DM code is transferred to the part after the heat treatment. The method that the matrix surface is directly engraved in the prior art is changed by the manufacturing method provided by the invention; the manufacturing method first deposits a high temperature resistant film on a matrix surface through a physical method, then carries out a laser labeling method; the high temperature heat treatment resistant performance of the DM code label formed by the manufacturing method is largely improved; besides the manufacturing method is suitable for being used under a high temperature environment, the coating tightly binds with the matrix, the parts processed by the manufacturing method are suitable for being subjected to a stress relief treatment, an aging treatment and a tempering treatment.
