1 . People have different ways of dealing with a common cold. Some take over the counter medicines such as aspirin while others try popular home remedies(治疗) like herbal tea or chicken soup. Yet here is the tough truth about the common cold: nothing really cures it.
So why do people sometimes believe that their remedies work? According to James Taylor, professor at the University of Washington, colds usually go away on their own in about a week, improving a little each day after symptoms peak, so it's easy to believe it's medicine rather than time that deserves the credit, USA Today reported.
It still seems hard to believe that we can deal with more serious diseases yet are powerless against something so common as a cold. Recently, scientists came closer to figure out why. To understand it, you first need to know how antiviral drugs work. They attack the virus by attaching to and changing the surface structures of the virus. To do that, the drug must fit and lock into the virus like the right piece of a jigsaw(拼图), which means scientists have to identify the virus and build a 3D model to study its surface before they can design an antiviral drug that is effective enough.
The two cold viruses that scientists had long known about were rhinovirus(鼻病毒) A and B. But they didn't find out about the existence of a third virus, rhinovirus C, until 2006. All three of them contribute to the common cold, but drugs that work well against rhinovirus A and B have little effect when used against rhinovirus C.
''This explains most of the previous failures of drug trials against rhinoviruses,'' study leader Professor Ann C. Palmenberg at the University of Wiscons in Madison, US, told Science Daily.
Now, more than 10 years after the discovery of rhinovirus C, scientists have finally built a highly detailed 3D model of the virus, showing that the surface of the virus is, as expected, different from that of other cold viruses.
With the model in hand, hopefully a real cure for a common cold is on its way. Soon, we may no longer have to waste our money on medicines that don't really work.

2 . Sam is a fourth-year student at Harvard Medical School，but poetry is still a big part of his life，now with a new teacher，Rafael Campo，who believes poetry can benefit every doctor’s education and work. Rafael is a physician，professor and a highly respected poet.
“Poetry is in every encounter(邂逅)with my patients. I think healing is really in a very great way about poetry. And if we do anything when we’re with our patients，we’re really immersing(使沉浸于)ourselves in their stories，really hearing their voices. And，certainly，that’s what a poem does，”he said.
Rafael worries that something important has been lost in medicine and medical education today：humanity，which he finds in poetry. To end that，he leads a weekly reading and writing workshop for medical students and residents(住院医生).
He thinks medical training focuses too much on distancing the doctor from his or her patients，and poems can help close that gap.
Third-year resident Andrea Schwartz was one of the workshop regulars. She said. “I think there’s no other profession other than medicine that produces as many writers as it does. And I think that is because there’s just so much power in doctors and patients interacting when patients are at their saddest. ”Not everyone believes that’s what doctors should do，though.
Rafael said，“I was afraid of how people might judge me，actually. In the medical profession，as many people know，we must always put the emergency first. But，you know，that kind of treatment，if it’s happening in the hospital，very regrettably，sadly，results in a bad outcome. The family is sitting by the bedside. The patient hasn’t survived the cancer. Don’t we still have a role as healers there?”
In a poem titled“Health”，Rafael writes of the wish to live forever in a world made painless by our incurable joy. He says he will continue teaching students，helping patients and writing poems，his own brand of medicine.

The doctors sent my mother home to die. As a fifteen-year survivor of breast cancer, she had suffered two heart attacks when advanced cancer was found in her lung. The doctor told me sadly, "She has a few days, maybe a week. Her heart is weak and unstable. "Mom had struggled to raise three daughters while holding a full-time job, yet worked hard to maintain a warm home for her family. My plan for Mom’s final days was simple: she would live with love, and die with grace.
I took mother to my home, small but comfortable, which was a heaven to four cats and a dog. The animals had the run of my house. We equipped the bedroom with an electric hospital bed and an oxygen machine, which frightened the cats. I’d moved their furniture and the cats were annoyed. The dog, on the other hand, an immature dog with bad habits, was excited by all the changes in the house. He jumped up, barking. He is Otto who was not afraid of the hospital bed, the oxygen machine or the medical smells. Nor was he afraid of the weak woman who had scolded him. Otto jumped onto the foot of Mom's hospital bed, and stayed. With the exception of eating and using the litter box, Otto never left Mom's room.
Days passed and Mom started to rally. “Not unusual,” I was told, “a rally is often a sign of imminent death(回光返照)” I was heart-broken. But Otto would not give her up so easily. He used her improved condition to reposition himself from the foot of her bed to her side. Her thin fingers found his soft coat. He leaned into her body, as if holding tight the strings of her will to live. Though weak, she petted the dog and would not allowed me to take him. Days turned into weeks and Mom continued to fight.
Paragraph 1
Once, after the nurses had gone for the day, I heard the sound of Mom’s voice coming from her room. __________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Paragraph 2
Three years later, Mom together with Otto is still here, medicines and nurses long gone. __ __________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
4 . In a major medical breakthrough, Tel Aviv University researchers have “printed” the world's first 3D vascularized (有血管的）engineered heart using a patient’s own cells and biological materials. Their findings were published on April IS in a study in Advanced Science.
“This is the first time anyone anywhere has successfully engineered and printed an entire heart,” says Prof. Tal Dvir of Department of Materials Science and Engineering, who led the research for the study. “This heart is made from human cells and patient-specific biological materials. In our process, these materials serve as the bioinks, something made of sugars and proteins that can be used for 3D printing of complex tissue models，” Prof, Dvir says. “People managed to 3D print the structure of a heart in the past, but not with cells or with blood vessels (血管).Our results demonstrate the potential of our approach for engineering personalized tissue and organ replacement in the future.”
According to Prof. Dvir，the use of “ native ” patient-specific materials is important to successfully engineering tissues and organs.
The researchers are now planning on culturing the printed hearts in the lab and “ teaching them to behave” like hearts, Prof. Dvir says. They then plan to transplant the 3D-printed heart in animal models.
“We need to develop the printed heart further，” he concludes. “The cells need to form a pumping ability ； they can currently contract (收缩），but we need them to work together. Our hope is that we will succeed and prove our method’s efficacy (功效)and usefulness. “Maybe, in ten years, there will be organ printers in the finest hospitals around the world，and these procedures will be conducted routinely. ”

5 . China is one of the first countries to breed a medical culture. In comparison with Western methods, traditional Chinese medicine (TCM) adopts a vastly different approach. For thousands of years, Chinese people have accumulated rich experience in fighting all sorts of diseases, therefore forming a unique medical theory under the guidance of ancient Chinese philosophies (哲学).
The core behind TCM is that the human body's life is the consequence (结果) of the balance between Yin and Yang. Yang functions to safeguard us against outer harm, and Yin is the inner base to store and provide energy. When the balance between the two aspects is disturbed, people fall ill.
One of the traditional techniques of TCM, acupuncture (针刺疗法) means insertion of needles into superficial (表面的) structures of the body—usually at acupoints (穴位)—to restore the Yin Yang balance. It is often accompanied by moxibustion (艾灸疗法), which involves burning mugwort on or near the skin at an acupoint.
The first known text that clearly talks about something like acupuncture and moxibustion as it is practiced today is The Yellow Emperor's Inner Canon. It is the earliest and most important written work of TCM and is considered the fundamental and most representative medical text in China.
Acupuncture and moxibustion have aroused the interest of international medical science circles. And TCM is gradually gaining worldwide recognition. The WHO issued a document in 2002 that appealed to more than 180 countries to adopt TCM as an alternative in their medical policies. In 2010, acupuncture and moxibustion of traditional Chinese medicine were added to the Representative List of the Intangible Cultural Heritage of Humanity by the UNESCO. Presently, TCM has been back in the news for its effectiveness in improving the cure rate of the COVID-19 since its outbreak in January 2020.

6 . LONDON—A smart toilet could offer a mini health check every time you take a seat, scientists said recently, but privacy campaigners and potential users said the idea sat uncomfortably with them.
The device would identify users through an anal(肛门) scan using a camera fitted under the seat before checking their waste for disease markers, including early signs of cancer, says the US-led team who developed the prototype(原型).
“We know it seems strange, but as it turns out, your anal print is unique,” said Sanjiv Gambhir, a radiology professor at Stanford University, who led work on the project. “The smart toilet is the perfect way to make use of a source of data that’s typically ignored,” Gambhir said. “Everyone uses the bathroom—there’s really no avoiding it—and that enhances its value as a disease-detecting device.”
A set of devices fitted inside the toilet bowl identifies the users and monitors their waste for signs of ill health which could be shared with their doctors, researchers said in the scientific journal Nature Biomedical Engineering. Such devices could become common place in homes, said Gambhir, as consumers accept health monitoring tools like smartwatches and internet-connected home devices. But many were concerned about releasing their privacy, the researchers found following a 300-person survey to assess acceptance. Three in ten respondents said they would not want to use a smart toilet, with only about half reporting they would be “somewhat” or “very” comfortable with it. The most commonly reported concerns were over privacy and data security, found researchers, who said information gathered would be stored in a secure, cloud-based system.
Despite those assurances, privacy campaigners expressed fears about security problems. “Health data contains the most sensitive and revealing information about anyone,” said Edin Omanovic, advocacy director at London-based charity Privacy International. “Linking it to someone’s biometric ID risks exposing private details to third parties, either through data sharing or security drawbacks which leave back doors exposed.”

7 . Gene therapy (基因治疗) is a revolutionary new technique for treating people with health problems. Up until very recently, the most commonly available methods for treating patients were either through drugs or operations. Gene therapy provides a third option for treatment by transforming or replacing cells with new genetic materials and instructions. Scientists can be very precise in the kinds of changes they make in patients.
Gene therapy works by using a delivery system, such as a virus, to enter a patient's body. Once inside the body, the virus combines with a host cell and delivers the new DNA. The proteins then begin to repair the affected cells. New techniques have focused on removing cells from the patients and transforming them outside the body before reintroducing them to the patients.
The two types of gene therapy are called somatic and germline. Somatic therapy refers to changing or replacing a body cell. In this case, the treatment is restricted to the patient only. This will not affect the patient's future children because the patient's germ (生殖) cells are unaffected. In germline therapy, the patient germ cells are treated, which may affect the patient's future generation.This is highly controversial (有争议的) because it is not clear exactly how this might affect them and further generations. For this reason, many countries have passed laws that prohibit this kind of treatment.
Despite the promise of gene therapy, there are still many barriers that need to be overcome before it comes into widespread use. One of the issues is that the use of viruses to deliver DNA may actually cause unexpected problems in patients if the virus grows and attacks the body. Another problem is the nature of many diseases is very complex and spread throughout multiple genes. The use of gene therapy to change a single gene in the body would probably not be sufficient as a cure. Finally, the costs of gene therapy are high. Some gene therapy procedures may cost over$1 million to undertake and require specialized doctors and equipment.

8 . Tell a child they need to experience another painful medical procedure, and you’ll probably have a kid filled with fear and anxiety. Tell that same child they’ll have a chance to strike flying cheeseburgers in outer space while their doctor works on them, and they might feel a little different.
That night-and-day difference in how kids respond to the treatment of their doctors is the reason for Lucile Packard Children’s Hospital Stanford’s innovative use of virtual reality technology. Packard Children’s lets kids participate in experiences that can significantly reduce their anxiety — and even their pain.
This isn’t the first time Packard Children’s has introduced those innovative methods. In 2015, Thomas Caruso, M.D., the founder of Packard Children’s Childhood Anxiety Reduction through Innovation and Technology (CHARIOT) program, introduced the Bedside Entertainment and Relaxation Theater (BERT). The system projects videos on a large screen attached to patients’ gurneys(装有轮子的床) so they can watch movies and music videos all the way to the operating room. And in early 2017, CHARIOT launched an interactive video game called Sevo the Dragon, which projects on the BERT screen, so the tiniest patients have something fun to do while breathing medicine through a mask.
“Children shouldn’t grow up being afraid to go to the doctor to have a shot, but certain experiences can cause strong unreasonable fear that last into adulthood. Needle phobia(晕针) is a common example of that, and it is the primary reason adults avoid important immunizations(免疫) like flu shots.” Caruso told Stanford Medicine News Center.
VR distraction therapy is being used for kids at Packard Children’s as young as age 6 in specific areas like the emergency department, and the tool will be widely used in all of the Children’s Health’s surgery clinics by the end of 2020.
