Solution Overview

Problem

The relationship between blood adiponectin concentration and illness in obese patients is not sufficiently demonstrated, and there is a need for an effective anti-tumor agent that can inhibit carcinogenesis, particularly in the liver.

Innovation Solution

An anti-tumor agent containing adiponectin as an active ingredient, administered via injection, which inhibits carcinogenesis in various organs including the liver, with dosages ranging from 1 to 100 mg/kg/day, and can be used prophylactically or therapeutically.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If adiponectin is used as an anti-tumor agent, then carcinogenesis inhibition is achieved, but the relationship between blood adiponectin concentration and illness in obese patients remains insufficiently demonstrated

Engineering Contradiction:
Improveanti-tumor efficacyVSAvoidrelationship between adiponectin concentration and illness
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent performs preliminary research and investigation to establish the relationship between blood adiponectin concentration and carcinogenesis risk before clinical application. This preliminary action includes identifying obese patients with low adiponectin levels as high-risk groups and conducting foundational studies to demonstrate the correlation between reduced adiponectin and tumor development, thereby providing the scientific basis for subsequent anti-tumor treatments.

Inventive Principle:
Principle #10Preliminary action

2Object-affected harmful factors

If adiponectin concentration is reduced in blood, then carcinogenesis is promoted, but there is no sufficient demonstration of the relationship between concentration and illness

Engineering Contradiction:
Improvecarcinogenesis promotionVSAvoiddemonstration of concentration-illness relationship
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent implements a feedback mechanism by continuously monitoring blood adiponectin concentrations in obese patients and correlating these levels with illness outcomes and carcinogenesis risk. This feedback approach allows for the establishment of quantitative relationships between adiponectin concentration ranges and disease states, enabling risk stratification and personalized treatment decisions based on measured concentration levels.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces traditional mechanical observation methods with biochemical measurement techniques to accurately quantify blood adiponectin concentrations. By using specific biochemical assays and analytical methods, the patent substitutes subjective or indirect indicators with precise quantitative measurements, thereby reliably demonstrating the relationship between adiponectin concentration and carcinogenesis risk.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If conventional anti-tumor treatments are used, then tumor treatment is attempted, but they do not specifically address the role of adiponectin in carcinogenesis inhibition

Engineering Contradiction:
Improvetumor treatment effectivenessVSAvoidaddressing adiponectin-specific mechanism
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by targeting the specific adiponectin pathway and mechanism in anti-tumor treatment rather than using general non-specific chemotherapy or radiation. This involves developing treatments that specifically address adiponectin deficiency or dysfunction, such as adiponectin replacement therapy or agents that enhance adiponectin signaling, thereby providing tailored treatment that addresses the unique mechanistic role of adiponectin in carcinogenesis inhibition.

Inventive Principle:
Principle #3Local quality

AI summary

The present invention provides a new anti-tumor agent containing adiponectin as an active ingredient, particularly, an anti-tumor agent capable of inhibiting carcinogenesis in the liver, use of adiponectin as an anti-tumor agent, and a prophylactic or therapeutic method against a tumor using adiponectin. The administration form may be either oral administration, e.g., by tablets or parenteral administration, e.g., by injection; in the case of intravenous injection for inhibiting carcinogenesis in the liver, the dosage is 1 to 100 mg/kg/day per adult patient.
