Is the level of human medicine somewhat primitive relative to the complexity of the human body?

Let's start with a philosophical perspective: looking at medicine with an agnostic attitude often gives specious questions and answers. Then back to the topic, man is precise, and medicine as the object is a kind of "science" of man, and its rigor and precision are at least not inferior to other "science".

From a macroscopic perspective of the human body, modern medicine (Western medicine) is large enough to transplant allogeneic organs to restore the health of patients; It is small enough to use a catheter to swim in the most delicate human brain to eliminate blood clots and unblock blood vessels; wide enough to graft skin for 99% of burn patients, saving him from pain; Lesions the size of a grain of rice can be punctured from a blood vessel filled liver with a thin needle guided by imaging technology.

This is not just the word "technology", it is already an art, an art that allows life to continue. From a microscopic point of view, molecular medicine can enable cancer patients to receive ** targeting a certain gene, which was unimaginable in the past, but more patients died from the side effects of chemotherapy of cytotoxic drugs; Molecular medicine can screen the health of the fetus still in the mother's body to avoid tragedy for families, especially those in high positions. From the perspective of medical methodology, modern medicine has a set of sophisticated statistical testing methods to screen the best schemes, so that doctors do not need to let patients taste "herbs".

Modern medicine also has a set of tools called evidence-based medicine, which can make the diagnosis and treatment behavior logical and coherent, and there is no longer a need for "experience is king". There is no such thing as barbarism—unless you think barbarism is the holding of a knife in your hand. <>

Nowadays, the understanding of many diseases and physiological mechanisms is becoming more and more profound, and it is possible to determine what kind of signaling molecules, what pathways, what genes, and how they are expressed. However, the biggest problem of individual human beings is that there are too many influencing factors and too many variables, and it is impossible to achieve univariate analysis at the level of the entire human body. All kinds of signals affect the whole body, so it is still very difficult to achieve targeted control.

Most importantly, due to ethical limitations, the study of human beings is actually limited to debugging. If only every scientist could study people like rats. Or even cultivated at will, changing human genes. Then the development speed of human life sciences is definitely much faster.

If nothing else, now release the restrictions on human cloning. The whole world has come together to set a standard human body. Then there are mass cloning.

Soon, the corresponding ripening techniques will be developed. The trial cycle will get shorter and shorter, and then the cost of various gene knockouts, additive tests, etc., will continue to fall. The speed of development of human life sciences is absolutely faster than all other sciences.

After all, the fear and desire for death are the driving force behind human action. <>

This may be true if compared to engineering. Whether it is clinical practice or scientific research, the farther you go, the more you find your own powerlessness and the powerlessness of human existing knowledge. The surgeon knelt and licked the man's self-healing thigh like a loyal dog, trying his best to create convenient conditions for him, hoping that he would work hard to repair the damage.

Physicians are overwhelmed by the large net of body fluids, endocrine, and neurovascularity that affect the whole body.

Scientists look at the dense network of proteins, genes, and factors that are still growing in association maps, and can't help but think about what one of the tens of thousands of factors that have been cross-linked in the past ten years can be explained, and even feel that they can't fully grasp the truth of this whole map by exhausting the limits of human intelligence. Perhaps compared to an auto repair engineer, a doctor is at most a schoolboy who steals and dismantles his father's car in a garage. However, we have achieved more in 100 years than in the last 6,000 years combined, and I think we are proud enough.

More than 2,000 years is the Han Dynasty of China, how much difference can there be?
