3 . Scientists have transfused (输血) lab-made red blood cells into a human volunteer in a world-first trial that experts say has major potential for people with hard-to-match blood types or conditions such as sickle cell disease. The research could someday mean an end to long searches for compatible donors (匹配的捐赠者) or dangerous transfusion reactions.
The experimental transfusion was done at Addenbrooke’s Hospital in Cambridge, England, as part of a joint effort among UK scientists to understand how lab-made blood transfusions could work.
The scientists took whole blood from donors in a UK database and separated out the stem cells. These are the body’s raw materials — the cells from which all specialized cells,like a red blood cell, can generate.Researchers grew red blood cells from those stem cells and transfused them into two healthy volunteers.
The transfusions involved only a tiny amount of blood: about one or two teaspoons. A standard blood transfusion would involve many hundred times that amount. This stage of the trial involves two mini transfusions at least four months apart, one with a standard donation of red cells and the other with lab-made cells from the same donor.
The researchers are closely monitoring the volunteers to determine whether the process was safe. They say there have been with“no unexpected side effects” so far. They’re also watching how long the lab-grown cells last compared with an infusion of standard red blood cells. Red blood cells typically last about 120 days, but a transfusion from a standard donation contains cells that are a variety of ages because the bone marrow (骨髓) continuously makes these cells.
Previous tests have shown that manufactured cells function like normal cells and that these lab-made cells are likely to survive longer overall while in circulation. This study will determine for the first time whether that’s true.
Further trials will be necessary to determine whether there could be a clinical use of this lab-grown product.
The research could eventually make a difference for people with sickle cell disease, those who. develop antibodies against most donor blood types, or those with genetic disorders in which their bod can’t make red blood cells or the blood cells they make don’t work well.

4 . Cognitive Processing Therapy(CPT), a long-term psychological therapy, is a specific type of cognitive behavioral therapy which reduces post-traumatic stress disorder (创伤后应激障碍) symptoms after natural disasters. Typically, CPT is delivered over 12 sessions to help patients learn how to modify negative attitudes and practices related to their trauma. The goal is that the patient then creates a new, more positive view and understanding of the traumatic event, which reduces on-going negative effects on the patient’s current life. It specifically focuses on the core trauma themes of safety, trust, power and control, etc.
Delivered both individually and in structured group sessions, it allows for multiple different paths to receive effective treatments. In some studies, it has shown to be helpful in cases where medicine alone has not worked. Because CPT focuses on retraining thoughts and behaviors to form practical strategies that can be applied to everyday life. Compared to other talk-therapies, it has been especially successful, because it can be completed in a brief period of time, allowing for a lower patient dropout rate. It also enhances brain connectivity, which lessens long-term impacts of trauma. This increased connectivity is why cognitive behavioral therapy is often argued to be more effective than medicine.
On the other hand, there are also multiple disadvantages to CPT. Due to its structured nature, it may not be suitable for people with more complex mental health needs or learning difficulties. Additionally, since it involves facing up to emotions and fears, patients may experience initial periods of additional anxiety or discomfort. Some therapists also argue that because it only addresses current problems and specific issues it does not address possible fundamental causes of mental health conditions, and because it focuses on the individual’s capacity to change themselves it does not address wider system problems that have a significant impact on a patient’s health and well-being.
However, focusing mainly on post-natural disasters, regardless of pre-disaster health, CPT has been repeatedly proven to be a rather successful treatment approach. Although there have not been studies generalizing CPT for children, it is an effective treatment for adults. The clear effectiveness of CPT demonstrates the importance of patient-specific therapies that are unique to the experiences of individual patients.

9 . As the coronavirus pandemic spread out, the demand for smell training therapy (疗法) stepped up, as potentially millions of those who had COVID-19 experienced losing their sense of smell.
Unlike some other viruses that can cause the loss of smell by directly infecting cells involved in detecting smell, the virus that causes COVID-19 spares them. Instead, the coronavirus infects surrounding support cells. To defend the body against the virus, immune cells rush to this site of infection and generate antiviral proteins, which then lead to the loss.
Approximately 80% of COVID-19 patients who had lost their sense of smell regained it without any treatment within one to four weeks. But as three months went by, patient Chris Rogers’ situation barely improved, so he started to seek out smell training therapy.
Twice a day for 10 weeks, Rogers sniffed four kinds of essential oils—rose, lemon, eucalyptus, and clove—to potentially strengthen the survival of newly formed smell-detecting cells or speed up their production and rebuild the connection between his nose and brain. To assess whether this smell therapy was effective, the doctor asked Rogers to distinguish between a number of additional smells before and after the smell training. Rogers did the therapy for 10 weeks and started noticing improvements at week six. At least five months since the smell training ended, the improvements can be more like 75%.
While scientists have recorded improvements in some individuals’ ability to smell, it has been difficult to show how much of that improvement comes from the therapy itself or natural recovery occurring over time, said Eric Holbrook, a doctor at Massachusetts Eye and Ear Hospital. “But I continue to recommend the therapy because such training could speed up the healing process. Also, it’s one of very few and often the only therapeutic options that’s available to millions of COVID-19 patients who haven’t been able to regain their sense of smell for months,” Eric Holbrook added.
Although the benefits of smell training can vary considerably among patients, depending on their starting point, “it is generally not considered harmful,” says Bradley Goldstein, a specialist studying at Duke University. “But we still need to find specific, more effective drug therapies. It’s really an unmet need.”

10 . Hundreds of millions have rolled up their sleeves for the COVID-19 vaccine, but why haven’t they rolled up their pants instead? What’s the science behind why we get most vaccines in our arm?
Most vaccines are given in the muscle—this is known as an intramuscular injection (肌肉注射). Some vaccines, are given orally. Others are given just beneath the skin.
But why is the muscle so important, and does location matter?
Muscles make an excellent vaccine administration (药物的施用) site because muscle tissue contains important immune cells. These immune cells recognize the antigen(抗原), a tiny piece of a virus or bacteria introduced by the vaccine that stimulates an immune response. In the case of the COVID-19 vaccine the immune cells in the muscle tissue pick up these antigens and present them to the lymph nodes(淋巴结). Injecting the vaccine into muscle tissue keeps the vaccine localized, allowing immune cells to sound the alarm to other immune cells and get to work. Once a vaccine is recognized by the immune cells in the muscle, these cells carry the antigen to lymph vessels, which transport the antigen-carrying immune cells into the lymph nodes. Lymph nodes, important parts of our immune system, contain more immune cells that recognize the antigens in vaccines and start the immune process of creating antibodies.
Muscle tissue also tends to keep vaccine reactions localized. Injecting a vaccine into the deltoid (三角肌) muscle may result in local inflammation(发炎) or soreness at the injection site. If certain vaccines are injected into fat issue, the chance of painful redness or swelling increases because fat tissue has poor blood supply, leading to poor absorption of some vaccine components.
Yet another deciding factor in vaccine administration location is the size of the muscle. Adults and children aged three and older tend to receive vaccines in their upper arm in the deltoid. Younger children receive their vaccines mid-thigh(大腿) because their arm muscles are smaller and less developed.
Another consideration during vaccine administration is convenience and patient acceptability. Can you imagine taking down your pants at a clinic with strangers around? Rolling up your sleeve is much easier and more preferred.
