Everyone can make slides
PowerPoint has played an important role in shaping the way information communication is carried out in modern society, and has become synonymous with the workplace world, and is an inseparable tool for almost every professional.
In 1987, PowerPoint was released as the digital successor to the projector, by software company Forethought. Previously, making slides was a labor-intensive task, often assigned to the design department or outsourced. PowerPoint allows anyone with computer access to make slideshows with just mouse clicks and rearranging information. As a software engineer, Austin worked with Robert Gaskins, the Forethought executive who conceived the software, to design PowerPoint to be easy to use. A few months after PowerPoint launched, Microsoft acquired Forethought for $14 million. Microsoft founder Bill Gates was skeptical at first, but eventually changed his mind. The project was so huge that Microsoft created a new business unit. Microsoft eventually added PowerPoint to the Office suite of programs, which was released on the Windows operating system in 1990. By 1993, PowerPoint had more than $100 million in sales. Today, users worldwide use PowerPoint to create more than 30 million presentations every day. For post-90s netizens, many people only know today that PPT is invented by Austin, and at the same time said that PPT makes people in the workplace love and hate ↓", "You can not like PPT, but I have to say that it is a great scientific and technological invention", "May there be no PPT in heaven";
Lung cancer is difficult to detect in the early stage of these 5 conditions in the body, be careful that early lung cancer basically has no obvious symptoms. When the tumor grows to a certain extent, that is, it has entered the middle and advanced stages, it will show obvious symptoms. At this time, the tumor compresses the lungs, trachea and other organs, and the patient will have clinical reactions such as cough, sputum, chest tightness, shortness of breath, and even difficulty breathing, which is the reason why lung cancer is found in the middle and advanced stages. Although lung cancer is difficult to detect early, it is not untraceable. Common symptoms of lung cancer include cough (8%~75%), blood in sputum, hemoptysis (6%~35%), chest tightness and shortness of breath (3%~60%), chest pain (20%~49%), hoarseness (0~2%), unexplained weight loss (0~68%), etc. If the patient has the following symptoms, attention should be paid to vigilance at this time. 1. Cough cough is the first symptom of lung cancer, as the tumor gradually enlarges to stimulate the bronchial mucosa, resulting in irritating cough, showing paroxysmal, even if cough suppressants, the effect is not great. 2. Blood in sputumSome lung cancer patients have blood in their sputum and sometimes cough up blood. This is because tumor tissues have a rich blood supply, and severe coughing is prone to blood vessel rupture and bleeding. If there is always blood in the sputum or a small amount of coughing up blood recently, you need to go to the hospital in time for relevant examinations. 3. Hoarseness Many lung cancer patients may have mild or heavy hoarseness, hoarseness is sudden, and the development speed is fast, so that the voice disappears completely in a short time, and there is no effect through conventional treatment. 4. Chest and back pain When the tumor grows relatively large, compresses blood vessels, nerves, and invades the pleura, pain will occur, and it is worth noting that the location of the pain is uncertain but will show persistence. 5. Edema appears in the area above the lungs, and tumor compression of the superior vena cava may lead to superior vena cava syndrome. Superior vena cava syndrome is characterized by edema of the face, head and neck, and edema of both upper extremities. "Early detection, early diagnosis, early treatment". Surgery is currently the only radical treatment that is recognized, and the earlier it is detected, the higher the chance of radical surgical resection.
