2 . Scientists from Imperial College London have found that using virtual reality(VR)headsets can reduce sensitivity to pain, by immersing(沉浸)people in icy Arctic scenery. In a study published in Pain Reports, a team from Imperial used VR video to reduce people’s sensitivity to ongoing pain and sharp shooting pain.
According to the researchers, the findings add to the growing evidence for the potential of VR technology to help patients with long-term pain. Beyond the distracting effect, they think VR may actually cause the body’s own inbuilt pain-fighting systems to start working.
Dr Sam Hughes, the first author on the paper, said "Our work suggests that VR may be getting involved in processes in the key parts of our inbuilt pain-fighting systems and are helpful in regulating the spread of increased sensitivity to pain.
To test their theory, researchers applied a cream containing capsaicin(辣椒素)-the chemical that makes your mouth bum-to 15 healthy volunteers. The capsaicin makes the skin more sensitive to painful stimuli(刺激)like a very small electric shock.
In the first trial, participants were then asked to rate the pain caused by the capsaicin cream on a scale of 0-100 (from 'no pain' to 'worst pain possible' )while either watching a VR scene of Arctic exploration through a headset, or looking at a still image of an Arctic scene on a monitor. Under the same conditions, they were also asked to say when a stimulus applied directly to the skin area is considered as painful.
The team found that ongoing pain was reduced following VR immersion, and that sensitivity to painful stimuli was also reduced. However, the same effect was not seen in people who looked at still images of the polar environment.
They explain that while the findings made at the beginning are encouraging, the study is limited by the small number of healthy participants, without long-term pain. However, the researchers believe VR could hold a bright future to treat patients with long-term pain who have poor inbuilt pain fighting systems.

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.

9 . How to Do basic first Aid
Basic first aid refers to a temporary form of help given to someone who has been injured or has got sick due to choking, a heart attack, drugs or other medical emergencies.
Care for the person who has just gone through serious damage, including both physical treatment and emotional support.
Perform 30 chest compressions (心肺复苏) and two rescue breaths as part of CPR.
Make sure the person is warm as you wait for medical help. Remove some of your own clothing, such as your coat or jacket, and use it as a cover until medical help arrives. However, if the person has a heatstroke (中暑), do not cover him or keep him warm.
A.Instead, try to cool him |
B.Remember to stay calm |
C.Perform first aid immediately |
D.Here are some tips for first aid |
E.It is important to take the correct chest compressions |
F.In the center of the chest, put your two hands together first |
G.If a person is in a state similar to sleep, he may need checking for breath |
10 . Painkillers (止痛药) are turning out to be a real pain: according to a new study in the British Medical Journal. Taking them for just a week can increase your risk of heart attack by 50%. The research suggested that the risk related to the use of certain drugs was greatest with higher doses (服用量) and during the first month of use. The potential risk may increase by 75% for medicines like ibuprofen (布洛芬) and naproxen, and more than 100% for rofecoxib.
It all sounds bad but, your risk is very low, — say, one in a million — a 100% increase means you still only have a two in a million chance. Of course, all painkilling medication that works can have side effects — nothing is safe and effective. Paracetamol (扑热息痛) has very few unless taken too much, in which case it can cause serious liver danger, but it isn’t very effective. Drugs like opiates are strong painkillers but easy to be addicted and often have other bad effects. Maybe you find that you are in a dilemma now. But don’t despair; you can refer to a pain clinic for some professional guidance. For ongoing pain, music and exercise may be the best choices to help you reduce the feeling of it.
Scientist at Harvard have recently done a quite horrible study on mice. They made the mice experience extremes of hot and cold, applied pressure to their back legs and injected the capsaicin (辣椒素) into their feet. And then they timed how long it took them to respond to the pain. Lack of sleep increased the discomfort, while stimulants (兴奋剂) such as caffeine made them less responsive to pain. This has been widely reported that a good night’s sleep and a cup of coffee in the morning may help reduce pain.
But anyway, don’t throw the pills away because the study also shows taking small doses of drugs, such as for short periods of time can be effective and safe as long as your heart is in good condition.
