Discussion of difficult cases in the Department of Respiratory and Critical Care Medicine.
For detection of pulmonary nodules.
The question of how to deal with the situation on a case-by-case basis.
Zhong Nanshan shared his latest research.
- Lung knotsSection Artificial Intelligence Diagnostic System
In the examination population,About 30% of people have a nodule on CT。However, not all pulmonary nodules have typical radiographic findings, soThere is a risk of being misdiagnosed。We found through our surveysThe rate of false resection of pulmonary nodules in general hospitals is close to 20%.。Nowadays, weThrough the artificial intelligence diagnosis system of pulmonary nodules, the false cut rate can be reduced to 8%.
It is reported that the artificial intelligence diagnosis system for pulmonary nodules has the functions of intelligent identification of lesions, judgment of benign and malignant lesions, gene mutations**, automatic reporting, etc., to help the accurate diagnosis and treatment of pulmonary nodules and lung tumors, and reduce the probability of misdiagnosis and missed diagnosis.
Regarding the recent significant increase in patients with respiratory diseases, Zhong Nanshan believes that there are two main reasons why respiratory diseases have entered a high incidence periodGeneral causes, that is, after the weather is cold, the immune function of the nasal mucosa is reduced, so the virus can easily enter the respiratory tract. The second isBecause wearing a mask for a long time can also make the autoimmune system unable to function normally, weakening the ability to resist diseases
Zhong Nanshan said, "Unless there is a time of the virus pandemic, or go to a place where people gatherLong-term wearing of a mask is not particularly advocated
Guidelines on Wearing Masks for the Prevention of Respiratory Infectious Diseases.
(2023 edition).
Wear masks scientifically.
It is an effective measure to prevent respiratory infections.
So. What should I pay attention to when wearing a mask?
1.

2.If you have symptoms of respiratory infections such as fever, cough, runny nose, sore throat, muscle aches, and fatigue, and go to indoor public places or have close contact with others.
3.When going to a medical institution for medical treatment, escort, escort, or visit.
4.During the period of high incidence of respiratory infectious diseases, when outsiders enter places where vulnerable groups such as elderly care institutions, social welfare institutions, and childcare institutions are concentrated.
5.During the period of high incidence of respiratory infectious diseases, public service personnel such as medical care, catering, cleaning, and security in key institutions such as elderly care institutions, social welfare institutions, childcare institutions, and schools work.
2. Situations or scenarios in which it is recommended to wear a mask1.When using public transportation such as airplanes, trains, coaches, ships, subways, and buses during periods of high incidence of respiratory infections.
2.During the period of high incidence of respiratory infectious diseases, when entering supermarkets, theaters, passenger terminals, van elevators and other places with closed environments and dense crowds.
3.During the period of high incidence of respiratory infections, the elderly, people with chronic underlying diseases, pregnant women, etc., go to indoor public places.
4.During studying, living, or working with a person with symptoms of a respiratory infectious disease.
3. Common situations or scenarios where it is recommended not to wear a mask1.When doing physical activity.
2.When you are in an outdoor place such as an open-air plaza or park.
3.Infants and toddlers aged 3 years and under.
Fourth, the choice of masks1.Patients with respiratory infections or those with symptoms of respiratory infections are recommended to wear protective masks with particulate matter such as N95 or KN95 (without breathing valves) or medical protective masks, and other personnel are recommended to wear disposable medical masks or medical surgical masks.
2.Children with respiratory infections or symptoms of respiratory infections are recommended to use children's protective masks, and other children are recommended to use children's sanitary masks.
3.Mask products should comply with relevant national standards or industry standards.
5. Other precautions1.Individuals can choose whether to wear masks according to their own health conditions and needs, and pay attention to changing them in time.
2.Patients with cardiopulmonary dysfunction should wear masks under the guidance of a doctor.
3.Local disease control departments should promptly and dynamically release the epidemic situation of local respiratory infectious diseases, and remind the public to wear masks scientifically.
