4 . Many people have dreamt to find a cancer cure. Now, a pill might provide some insight into their dreams.
The medicine, AOH1996, also called the “cancer-killing pill”, explicitly targets the protein that encourages cancer cells to spread across the body. It prevents proliferating cell nuclear antigen (PCNA 细胞增殖核抗原) with a tiny molecule. Up to August 2023, it is being evaluated in Phase I clinical studies for the treatment of solid cancers.
Cancer is a condition in which abnormal cells continue to proliferate uncontrollably, causing the tissue to be destroyed. About one in six deaths were due to cancer in 2020, making it the top cause of death globally.
According to a recent study published in Cell Chemical Biology, City of Hope researchers have discovered a novel method to treat cancer using a special tablet that can get rid of solid tumors. AOH1996 differs from other targeted cancer therapies in this respect, where other approaches may cause a tumor to change and develop more resistance to treatment.
According to City of Hope Professor Linda Malkas, the research team created a medicine specifically targeting the kind of PCNA seen in cancer cells since data indicate that PCNA is distinctively changed in cancer cells. The novel cancer medicine acts like a snowstorm closing a significant airport, stopping only flights from and to aircraft carrying cancer cells.
“Results have been promising. AOH1996 can prevent tumor growth in cell and animal models. The drug is currently in Phase I clinical trial in humans at City of Hope.”
Treatment of lung, brain and skin cancers with AOH1996 has shown to be effective. It kills specific cells by stopping them from replicating (复制) typically. To assess this medicine for potential future use, more clinical studies are planned.

7 . When colds and flu hit, many people automatically turn to over-the-counter (OTC) medicines to push through and treat their symptoms. Although these medicines are easily accessible and widely used, it might come as a surprise to many people to learn that they are not risk-free. A study estimated that every year, 26,735 people went to the emergency room for adverse (不利的) events related to OTC cold and cough medicines.
When two or more drugs are used together, their interactions can sometimes produce unexpected harmful effects. Physicians are typically knowledgeable about potential drug interactions, so it is very important for patients to ask their healthcare providers which OTC medicines are safe for them to use.
It is important to read the package ingredients of OTC medicines closely to avoid duplication of doses (剂量重复). Cold medicines are typically made up of multiple ingredients. A person who takes a single-ingredient medicine paired with one of these multi-ingredient medicines can receive an unsafe dose of that ingredient.
While everyone could potentially experience adverse effects from cold and flu medicines, some groups — including older adults, children and pregnant women — may be at greater risk. Older people who are using prescribed drugs to treat multiple health conditions may have a higher risk of drug interactions because of the higher number of medicines being used at the same time to treat different conditions. The aging body is not as expert at absorbing, distributing and clearing medicines as younger bodies are. This can put older adults at higher risk for an overdose and drug-to-drug interactions with some medicines.
The Food and Drug Administration and the Centers for Disease Control and Prevention do not recommend giving cold medicines to children under age 4. Because of a variety of factors, young children have a higher risk of an accidental overdose and adverse events that could lead to death.

Since January 2022 about 460,000 people in England who suffer from atrial fibrillation(AF)- a dangerously irregular heart rate-have begun taking one of four anticoagulant(抗凝血剂) drugs that are proved to reduce stroke risk. Speedy introduction of the drugs has kept 4,000 people alive who would otherwise have died and prevented about 17,000 strokes, according to Amanda Pritchard. Strokes kill about 27,000 people a year in England and lead to about 120,000 being taken to hospital.
A drive to encourage take-up of the drugs means 90% of the 1.5 million people in England with AF are using them. That should result in fewer strokes, which are a leading cause of death and disability, given that AF causes about one in five strokes.
“The rapid introduction of these drugs is a big step forward in providing the best possible care for patients with heart disease”, Pritchard, the leader of NHS(National Health Service) England, will say in a speech today at the King’s Fund health experts’ yearly conference.
The drugs, called direct oral anticoagulants, help stop blood from clotting(凝血), therefore reducing the risk of a clot developing and causing a stroke. In 2021 the National Institute for Health and Care Excellence recommended that doctors use four anticoagulant drugs.
Dr Maeva May, the Stroke Association’s director, thought the widespread use of the drugs as “fantastic news”, because AF accounts for one in five strokes and strokes in people with AF are more likely to result in death or serious disability.
NHS England has used its spending power to cut deals with the makers of the four drugs, which has made them much more widely available. The British Heart Foundation praised the NHS’s “great progress towards its goal of reducing stroke deaths”.
