'I don't know how it works'

Dr Huang Hongyun cultivates the cells of aborted
foetuses and injects them
into the brains and spines of his patients. His method
is controversial, but
his results have led hundreds of westerners to his
Beijing surgery. Jonathan
Watts was given unprecedented access to the doctor and
his patients Jonathan
Watts Wednesday December 01 2004 The Guardian


They come to him in search of miracles. The lame, the
sick and the dying;
young and old; Christians from the US, Muslims from
the Middle East,
Buddhists from Japan, agnostics from Europe. Some have
been in wheelchairs
for years and believe he can help them walk; others
are kept alive by
respirators, yet hope he can make them breathe. The
voiceless have heard he
can bring them speech. The terminally ill seek nothing
less than more life.
In many cases doctors and friends advise them to stay
at home, not to waste
their money, and warn them of potential risks. 

For they come in search of one of the most pioneering
- and controversial -
medical procedures on the planet: the injection of
cells from aborted
foetuses into the brains and spines of the sick. And
the object of their
faith is a Chinese surgeon who spent many of his
university years labouring
as a peasant and is now conducting trial-and-error
experiments on live
subjects despite his research being rejected by the
western medical
establishment.  

Dr Huang Hongyun promises nothing. He claims no
miracle cure. He admits he
cannot fully explain his results. All he knows, and
all he tells his
patients, is that his method often works, that the
results speak for
themselves. "Our results change thousands of years of
traditional concepts,"
he says.   

The conventional wisdoms that he claims to have turned
on their heads are
that chronic spinal injuries - injuries that can cause
paraplegia or
tetraplegia - can never be treated; and that it is
almost impossible to
stabilise the condition of patients with the wasting
disease amyotrophic
lateral sclerosis (ALS), also known as Lou Gehrig's
disease.  

"Our results show that is wrong. It is not a miracle,
but it is a big
change." And in this cyber age - when many people
trust the internet more
than their own doctors - this is proving to be enough,
because the word on
the web is that Huang's results are miraculous. Chat
sites for paraplegics
and ALS sufferers are buzzing with testimonies from
former patients who say
they are walking, talking and scratching their noses
for the first time in
years.  

None of these claims has been proven to western
scientific standards, but
Huang's willingness to think the unthinkable in order
to cure the incurable
is inspiring hope; so much hope that patients are
putting aside ethical
qualms, paying tens of thousands of dollars and flying
to Beijing to act as
his guinea pigs.  

Among them is Van Golden, a Christian, anti-abortion
Texan who has sold his
house so that he can travel to communist, atheist
China and have Huang
inject a million cells from the nasal area of a foetus
into his spine.
According to Golden's doctors, his spine was damaged
beyond repair in a car
crash last Christmas. The damage to his nervous system
was so bad that he
has been in a wheelchair and racked by spasms ever
since. But Golden refused
to give up, even if it meant having to compromise his
values. "This is the
only place that offered us any hope," he says.
"Everyone else offered only
to help make me sufficient in that chair. But the
chair is not my destiny.
It is not ordained."  

At first sight, the Xishan workers' sanitarium is an
unlikely destination
for a modern medical pilgrimage. Amid bamboo groves,
leafy promenades and a
rock garden, the mood is one of dilapidated
restfulness. Although this
establishment is cleaner and quieter than most Chinese
hospitals, the odd
bicycle can still be seen trundling through the
corridors.  

In the past month, something unusual has been
happening here: this clinic
has become the base for Huang's treatment of foreign
patients. The first
sign is the giant red banner strung across the
entrance, which bears the
English greeting, "Welcome to the new home." The next
is up on the third
floor, where a guard restricts access to a newly
painted ward full of
pink-uniformed nurses and patients, including Van
Golden.  

It cannot be easy for a man of his beliefs to be in
China, where the
government's one-child policy is partly responsible
for millions of
abortions each year. But instead of shunning the
system, Golden believes his
only hope is to embrace it. There is nowhere else he
could get foetal cells.
"I wish there was another way they could do it. There
are 4,000 abortions a
day in   the US. Partial-birth ones are murder on a
most terrible level.
What they are doing here is a whole lot more humane.  

"Four thousand a day. That's a waste. Something good
should come out of
something bad. The people who don't believe that
aren't in a wheelchair."
The day after we meet him, Golden takes his turn in
the operating room,
where Laura Fairrie, a film-maker with Guardianfilms,
has been given a rare
chance to film the controversial procedure.  

The scene is a familiar one: Huang and four other
doctors gloved and masked,
the patient knocked out with a general anaesthetic and
rigged up to a
respirator, electrocardiograph. A surreal touch comes
from the background
music: the melody on Huang's mobile phone, which rings
incessantly
throughout the five-hour surgery. Most of the time is
spent exposing the
area of the spine where the cells are to be injected,
which involves cutting
through muscles, then working around the bone to gain
access to the sections
of the spinal cord immediately above and below the
injury. Huang does not
decompress the spinal fluid or decouple the vertebrae,
which, some critics
have speculated, may be the reason for the temporary
improvement in patients
after surgery.  

Once the desired area adjacent to the damaged segment
is located, Huang,
looking through the keyhole incision with a
microscope, inserts the cells
using an ultra-fine needle to minimise the risk of
damaging nerve fibres.
The cells, harvested from the olfactory bulbs inside
the noses of foetuses,
seem to have unusual properties, which may include the
ability to stimulate
change in the nervous system. Ideally, says Huang, the
foetuses should be 16
weeks old to achieve the best results. He says the
mothers all give their
consent for the embryos to be used in this way and do
not receive payment.
The Guardian asked to be shown where they come from,
but was told this
information was too sensitive.  

Once harvested, these olfactory ensheathing cells
(OECs) are cultivated for
10-14 days using a medium that the doctor says he has
developed himself. He
is reluctant to go into the contents of this liquid,
but says it plays an
important role. In the process of culturing, the
number of cells multiplies
ten- or twentyfold, meaning that a single foetus is
enough to produce the 1m
cells used in Golden's operation - half a million
above and below the
damaged area.  

In the case of patients with ALS, the method is more
direct - and appears to
produce even more remarkable results. Huang simply
opens up the skull and
injects the cells - more than two million in this case
- into the atrophied
area of the frontal lobes. We were not allowed to see
this operation, but
one patient was able to describe it, because - to his
surprise - the
surgery was carried out under local anaesthetic.  

"I didn't know I'd be wide awake and feel everything,"
says Michael Thomas,
who has come here from Florida. "They didn't tell me
what to expect. They
just stuck a needle in my head, which hurt like hell.
I was wide awake, so I
could see and feel the drill going through my skull.
It looked like one of
those Black & Decker drills you use at home. The
drill got stuck so they
had to reverse it. It didn't hurt much, until the last
bit, when it popped
through." Then the surgeon injected the cells into his
brain. "I could hear
them inside my head: squish, squish. 'Is that the
cells going in?' I asked
Dr Huang."  

Although Huang is one of the first in the world to use
foetal OECs on
humans, research on cell implants goes back more than
two decades. In
western animal laboratories, researchers are testing
the possible benefits
of stem cells on neurological disorders, but Huang
dismisses such studies.
He says Chinese doctors have already attempted
stem-cell transplants on
humans with poor results. "In clinical trials in
China, stem cells have
failed to meet expectations. I believe that in two or
three years' time, US
doctors will realise this."  

The boast that China leads the world in this area of
medical science would
have been unbelievable a few years ago, but lower
ethical barriers have
allowed doctors here to conduct experiments not
permitted elsewhere.
"Chinese doctors have mixed many kinds of cells," says
Huang. "Some things
are legal in China that are not legal in the US."  

OEC cells do not replace damaged cells, says Huang,
but act as a catalyst,
which is beneficial to spinal-cord injuries, ALS,
multiple sclerosis,
Parkinson's disease and conditions caused by strokes.
"OEC cells are very
special. They show manykinds of growth factors. They
can change the local
environment, which helps nerve fibres and neurons
recover," he surmises.  

This, he believes, is why so many patients show a
sudden improvement after
surgery, long before the growth of the cells might be
expected to regenerate
the damaged nervous system. But when I ask him how it
works, he replies:
"Actually, I don't know. The mechanism is not clear.
But we must face the
facts. Any scientist who comes and sees the patients
will see the same
results as me."  

The patients appear to have no doubts. We spent a week
at the foreigners'
ward at Xishan   and then visited another institution
in central Beijing,
where Chinese nationals undergo similar operations.
All of the dozen
patients we spoke to reported improvements after
surgery - some small,
others dramatic. "Since I arrived here, I've seen so
many miracles," says
Laura Jackson, an American 15-year-old who was nearly
killed after she fell
in a cheerleading accident. The damage to her upper
spine was so bad that
doctors told her father that she would never breathe
by herself again and
asked if he wanted to switch off her life-support
system. But he and his
daughter refused to give up.  

Laura now uses a wheelchair and breathes with a
respirator, but she says she
has made progress under Huang. For the first time
since her accident, she
says, she can feel a muscle in her arm that gives her
hope she may one day
be able to brush her own hair. She also came off the
respirator for 15
minutes - during which she called the experts who
doubted Huang. "I don't
know why people deny it," she says.  

Even more dramatic changes were observed among the ALS
patients, many of
whom visibly picked up in posture and speech within
hours of the operation.
ALS is a progressive and ultimately fatal
neuromuscular disease that causes
nerve cells to degenerate and muscles to weaken.
Because the senses remain
unimpaired and the intellect is often unaffected, it
has been described as
like "living in a glass coffin". The Xishan ward
includes people who have
gone from muscle-bound weightlifters to scrawny
invalids barely able to lift
their heads.  

When we first see Roger Beirnaert, a builder from
Belgium, he looks as
though his pride has been crushed as badly as his body
by ALS. It is hours
before surgery and his head lolls forward on an
apparently useless neck as
drool escapes from his mouth. The next day he appears
to be a man
transformed: he lifts his head with an almost haughty
air and walks with
confident steps. His son Tony says his father can also
sleep without waking
every hour and having to be turned over because he
worries he is choking.
"He's laughing again and smiling," says Tony. "There
is an improvement. It
is difficult to say what more we expect. This is just
a beginning. Let's
hope for more."  

Another Belgian, Patrick Six, a former policeman with
ALS, was grumbling a
day after his operation that he was not experiencing
the rapid gains he had
expected. Two days later, he, his wife and his sister
Caroline are joining
the chorus of praise for Huang. They all say he can
talk more clearly,
though he still has to spell out many words that his
tongue is not strong
enough to form. For the first time in six months, a
beaming Six says, he can
flatten out his hand. "We know that stabilisation is a
big step," says
Caroline. "Anything on top of that is a victory."  

I ask Six whether he might be imagining the
improvements. "It is
impossible," he says. "Dr Huang is proving something
is happening here. My
Belgian doctor should come here for a month. I'd
recommend it to others with
my disease. It shows there is an alternative."  

Two days after his operation, Golden too has noticed a
change. "I can feel
more muscles firing again. The feeling is back in my
finger. My feet aren't
nearly as sensitive as before, my spasms have
slackened up and there is a
little more movement in my feet ... It is these little
things that build up
to big things. It's the hope."  

It is hard not to be swept away with the exultant mood
on this ward of very
driven, very desperate people. They expect so much
from Huang that they are
inclined to play down many of the risks and hardships
involved. It takes
some time before Golden acknowledges that the recovery
of sensation in his
fingers has actually brought pain - like needles being
inserted, he says.  

Others pay a bigger penalty. Two foreign patients have
died in Huang's care
in the past month. In both cases, the patients were so
sick that they might
well have died anyway, but the long flight and
rudimentary aftercare in
Xishan will not have helped their recovery.  

Western doctors are divided about Huang's work. His
critics say he is
exploiting desperate people to hone a technique that
has not yet undergone
rigorous testing and lacks any long-term follow-up.
"The general scientific
opinion is that this isn't properly controlled work. I
don't know anyone who
doesn't have an interest in what he's doing - and I
don't know anyone who
approves," says Professor Geoffrey Raisman at the
National Institute of
Medical Research, who is pioneering research on OECs
in Britain.  

But Huang also has prominent supporters, including
Paul Cooper, who runs the
spinal neurosurgery programme at New York University
medical centre. "Huang
isn't a charlatan," says Cooper. "What he is doing is
very impressive. I
don't understand it, but I've seen the results. He's
not raising people from
the dead, but people who have had no movement in legs
could move them,
people who couldn't sit up sat up, people who couldn't
hold a cup held a
cup."  

Huang's former teacher, Professor Wise Young, the
director of neurosurgery
research laboratories at New York University &
Bellevue medical centre,
is equally supportive - and perplexed. "I've seen it
with my own eyes;
there's no doubt that it happens. The problem is, the
results are too fast
for regeneration, therefore the mechanism for early
recovery is not known.
So we are now working hard to try to understand the
process in animals."  

Complicating the debate is Huang's lack of statistical
data and and his
refusal to carry out the double-blind trials
considered necessary in western
circles to rule out the placebo effect. The Chinese
neurosurgeon says such
tests are unethical because they involve cutting
someone open and only
pretending to treat them. "This would not be legal in
China," he says. "Even
if it was, I wouldn't do it. Double-blind trials only
harm the patient."  

Huang says he simply wants to cure as many people as
possible. Money, he
says, doesn't come into it. He still treats Chinese
patients who pay less
than half of the $20,000 fee levied on foreigners.
Although he is earning
his hospitals a small fortune, he says he gets only
$500 a month regardless
of how many operations he performs.  

His patients - foreign and Chinese - and their
families appear to adore him,
and to accept what he does with foetuses. Huang has
already operated on 500
people. Every month, at least a dozen more fly in. He
gets hundreds of new
inquiries a week and his waiting list for foreigners
now stretches until
next December. So many Chinese patients have asked for
treatment that he
says he could be busy for 10 years, even though he has
trained at least five
other doctors in the procedure.  

"We need 100 more Dr Huangs," says Laura Jackson's
father Daryl. "And we
need more cells. It's a different government over
here. They have to trim
the population. There are 15 to 20 million abortions
in China a year. If
everyone who was aborted could save a life, there
would be no sick people
left in the world." Golden's Christian wife, Debbie,
also sees Huang as an
idealist - particularly in comparison to the US
doctors who charged her
husband almost $1m, but were able only to make him
more comfortable in his
wheelchair.  

"In the US it's totally about money, but China is more
ethical," she says.
"They work harder. I'm American, so that is very hard
to say.  

"I don't agree with abortion, but it will happen
anyway. In the US, we do
abortions but don't use the cells. In China, they
don't just take life and
destroy it - they give something back. It's like
lemonade out of lemons. You
take something bad and you make it good." Such
reasoning requires a moral
somersault, but it is one that can be done easily in
China. That is enough
to generate hope.  

In the west, the debate about using cells from
foetuses looks set to
continue for decades. In China, it is a non-issue. As
a result, people who
are maimed or dying no longer have to wait for the
politicians and the
scientists to scrutinise the ethnical and medical
risks. There is a choice.
It is an uncertain one.  

The long-term impact of the surgery remains unknown,
but that does not
bother patients who would otherwise have only a few
years to live, nor does
it bother those like Golden who are willing to try
anything to get out of a
wheelchair. "People like me and the others in this
hospital are willing to
risk everything, even our lives. I'll be a guinea pig.
Some hope is better
than none."  

Four days after his operation, Golden and a couple of
other patients visit
the Great Wall of China, conveyed there by bus and
then wheelchair. The
sight of the world's biggest and oldest barrier
appears to inspire rather
than daunt the Texan, who now believes in the miracles
of a Chinese doctor.
"I want to come back here next year and walk the wall
for myself," he says.
