4 . The measurement of blood pressure goes back almost three centuries, leading to the procedure that we all know and that our family doctor performs when we have checkups: A cuff (袖口) goes around our arm, which is first inflated (膨胀), and then deflated (放气), in a controlled manner, to determine our maximum and minimum blood pressure.
But the use of inflatable-cuff blood pressure monitors has some disadvantages. For one thing, unless people have home monitors, they must go to a chemistry shop, doctor’s office or health center to learn what their blood pressure is. Another barrier is that repeated inflation and deflation of the cuff can cause difficulties when, for example, a patient is in the hospital and needs frequent blood pressure monitoring. And the last one is that since cuffs don’t allow continuous measurement of blood pressure, they’re only providing a measurement at a specific moment.
Today, a new generation of blood pressure devices have been developed and their aim is to make it easier to judge high blood pressure. Unlike traditional devices, they do without the arm cuff and offer blood pressure values on demand. Users just press their finger on a sensor on a watch and ring.
The various cuffless measuring devices are based on methods that, instead of directly determining blood pressure, use sensors to capture various indirect signals. These signals are processed by different sets of mathematical procedures to obtain the blood pressure values. It is like inferring fever by measuring an increase in heart beat and sweating instead of using a thermometer (体温表), or divining the result of a soccer match from outside the stadium by listening to the screams of the soccer fans.
The development of devices for measuring blood pressure without a blood pressure cuff is progressing rapidly, but that doesn’t mean they are ready used to make diagnostic and treatment decisions. “The road to clinical application may be some day in the near future, but not now,” Avolio says.

7 . Deveza’s mother was on the waiting list for a kidney transplant (肾移植). Deveza wanted to donate one of her own kidneys, but she was turned down because she might develop the same health problems as her mother in later life.
Deveza came up with a different plan. In 2017, she started the world’s first paired exchange of different organs between living donors, exchanging half her liver (肝) for someone else’s kidney. A case study of the organ exchange has now been published. And the surgeons who were involved are calling for more exchanges like this. “You can imagine the enormous impact for mixed organ extended chains,” says John Roberts, a surgeon at University of California, San Francisco.
Most organ transplants come from people who have died, but there are never enough organs. As most people can manage with just one of their kidneys, people with kidney failure are increasingly receiving donated organs from relatives or friends. If someone wants to donate but their immune (免疫的) system is unsuited, doctors may be able to find pairs of would-be donors who can each give a kidney to the other’s relative.
When Deveza was looking into such chains, she came across research describing the idea of trading a kidney with the only other organ generally taken from a living donor—the liver. She suggested the idea to many hospitals before she finally contacted Roberts, who saw the idea’s potential.
Deveza was assessed to be in good enough health to donate part of her liver. It then took 18 months to find Annie Simmons, in Idaho, whose liver was unsuitable to use as a transplant for her sister with severe liver disease. They drew up a plan: Simmons would donate a kidney to Deveza’s mother, and in return, Deveza would give half her liver to Simmons’ sister. The hospital gave the go-ahead and the four operations took place on the same day successfully.
The team hopes that the ground-breaking case will inspire more people to consider doing the same. Roberts says that direct exchanges involving two donors could enable up to thirty extra living donor liver transplants a year—a ten per cent increase.
