This blog posts starts with a 2018 paper that shows us that “External Qi” can kill lung cancer cells, but that lacks an explanation on what it exactly is. Going back in time trying to detangle a hairball of references, we end up in 2004 with a paper in Brain Research that explains how a Chinese Qigong master famous in the 1980’s and 1990’s can kill cancer cells and make other cells grow by using a special Qigong technique.
Let’s start with the most recent paper of this set that I could find.
Here it is:
“YXQ-EQ Induces Apoptosis and Inhibits Signaling Pathways Important for Metastasis in Non-Small Cell Lung Carcinoma Cells“
It is about “YXQ-EQ” that can inhibit lung cancer cells.
At first glance that sounds amazing.
So, what is this magical compound “YXQ-EQ”, you might ask. Excellent question. Let’s look at the abstract.
“This study was aimed to investigate cytotoxic effect of external qi of Yan Xin Qigong (YXQ-EQ) toward human lung adenocarcinoma A549 cells”.
Mmm, that sounds a bit vague. What is it, exactly?
The introduction text does not help a lot, either.
I want to stress here that it is not my intention to make fun of traditional Chinese Medicine. There are some medical therapies based on TCM. Here, I am specifically questioning the “YXQ-EQ” method.
Let’s take a look at the Methods section. Surely, we will learn more about how the researchers treated the cells with “YXQ-EQ”. After all, the Methods section of a scientific paper should have enough detail so that other researchers can reproduce the study.
There is nothing in the methods about the “YXQ-EQ” treatment.
No “Briefly, this involved…”. No reference. Only that it lasted 5 minutes.
A good reviewer should have asked for a detailed description of the magical treatment. If authors do not want to disclose the way they did something incredible, that could be a reason to reject. That is the strength of #PeerReview.
Apparently, none of the reviewers/editors asked this question.
Yet, this elusive method has great powers. It magically kills cancer cells, so how does it work?
Let’s look at the references about the “YXQ-EQ” method. There is a lot of self-citation going on here.
Let’s take a look at some of the other references about the mysterious “YXQ-EQ” treatment.
The name “Yan Xin Qigong” refers to the name of the first author. It is his method, and it appears that only the first author can perform this method.
There is another paper (same journal, 2013) with the Qigong master as first author, in which “YXQ-EQ” inhibits colon cancer cells.
“External Qi of Yan Xin Qigong Inhibits Activation of Akt, Erk1/2 and NF-kB and Induces Cell Cycle Arrest and Apoptosis in Colorectal Cancer Cells“
In a third paper, from 2012, “YXQ-EQ” inhibits growth of another cell line of lung cancer. It appears to work with many cancer cell lines.
And surely enough, the “YXQ-EQ” method can also kill off breast cancer cells, according to this 2010 paper.
None of these papers actually describes what “YXQ-EQ” entails. Here are some Methods section screenshots.
In none of these papers, reviewers or editors asked the right questions.
At least, we now have a reference to go to, from 2004.
After following a hairball of references, we are finally in the year 2004, at this paper published in Brain Research, by researchers from @Harvard, @UofOklahoma and @NIH. There are also some affiliations with alternative medicine institutes that appear to be hard to find online.
In this paper, the Qigong master will surely reveal to us how the method works. Here is the Methods section from the 2004 paper.
Here is a translation of the scientific language. Here is how YXL-EQ works:
The Qigong master will take the cancer cells to a private room, and will do something secret. So secret that he can only do it in a locked room. Then he will give the cells back. And voila – they are dead.
Maybe the master had brought a UV lamp? Or a bottle of bleach? Or a flame torch? Any of these methods could have killed the cells, but the door was locked, so it was not clear what happened in that room. I am open to other suggestions too. Or was the ‘miracle doctor’ not even in the room with the cells? The description is not very clear.
It is also not clear if the cells assigned to the control group were taken out of the incubator. If not, that by itself could have created crucial differences between the two groups.
Again, I want to say that I do not want to make fun of traditional Chinese medicine, or about anyone’s belief in Qi as an invisible force of life, or of anyone who enjoys practicing Qigong. You can read more about Qi here:
But if one single researcher claims that he – and only he – can use Qi to kill off cancer cells, he should be willing to share how they do that. If it happens behind closed doors, scientists have every reason to be suspicious.
But what is most bewildering is that there are at least 7 peer reviewed, Pubmed-indexed papers based on this mysterious technique.
Seven sets of peer-reviewers and editors who were not paying attention to the methods and reproducibility.
Also note that this work was funded by the @NIH .
This set of papers was brought to me in private by a concerned reader – I did not find them by myself. Not everyone is in a position to call out bad science, so thank you, concerned reader, for raising this issue.
Be like this concerned reader.
