Solution Overview

Problem

Current treatments for neurological diseases such as Alzheimer's, Parkinson's, and traumatic brain injury lack effective methods to evaluate treatment efficiency and address the complex mechanisms of neuronal damage and cell death, including glutamate excitotoxicity and mitochondrial dysfunction.

Innovation Solution

The method involves determining the efficiency of dextran sulfate treatment by measuring specific biomarkers in patient samples before and after administration, using a group of biomarkers to assess changes in platelet factor 4, tumor necrosis factor superfamily members, brain-derived neurotrophic factor, and other molecules to evaluate treatment efficacy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If dextran sulfate treatment is administered to patients with neurological diseases, then treatment efficiency can be evaluated through biomarker measurement, but the complexity of evaluating multiple biomarkers increases

Engineering Contradiction:
Improvetreatment efficiency evaluationVSAvoidbiomarker measurement system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The evaluation system is segmented into multiple biomarker groups (groups 1-6), each targeting specific molecular pathways. This segmentation allows systematic evaluation of different treatment mechanisms separately, making the complex multi-biomarker assessment more manageable and interpretable while maintaining comprehensive treatment monitoring.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The biomarker panel serves multiple functions simultaneously: it evaluates treatment efficiency, monitors disease progression, and identifies treatment response patterns. This multi-functionality reduces the need for separate evaluation systems and streamlines the overall assessment process despite the complexity of measuring multiple markers.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If multiple biomarkers from different groups are measured to comprehensively evaluate treatment efficiency, then evaluation accuracy improves, but measurement time and resource consumption increase

Engineering Contradiction:
Improvetreatment efficiency assessment accuracyVSAvoidbiomarker measurement time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The biomarkers are pre-categorized into six groups based on their functional relationships and treatment relevance. This preliminary organization allows clinicians to select and measure only the relevant biomarkers for each treatment scenario, reducing measurement time while maintaining comprehensive evaluation accuracy through structured approach.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system allows selective measurement of biomarker groups based on specific treatment needs and patient conditions. Clinicians can measure all six groups for comprehensive evaluation or select partial groups when certain biomarkers are sufficient for the clinical question, optimizing the balance between measurement precision and time consumption.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

The efficiency of dextran sulfate treatment is determined based on differences between the amount of biomarkers determined in a second biological sample taken from the patient following dextran sulfate administration and in a first biological sample taken from the patient prior to dextran sulfate administration.The biomarkers are selected from 6 groups consisting of PFA4and VAV3 (group 1); TNFSF15, IL-17B, TSLP and CRH(group 2); FGF1 and KITLG (group 3);BDNF, NOG and HBEGF (group 4);AFP,ATP2A3, SLC29A1,SLC40A1 and TTR(group 5);and SLC1A4, SLC7A11, SLC16A7, LDLR and ATP8A1(group 6).
