The gold content of a New York medical degree is high. A bachelor of medicine belongs to a science student, but it has a higher gold content than an average science student, because a bachelor of medicine studies in school for five years, and after graduation, he also does three years of training, which is often referred to as the 5 3 system. The learning difficulty is more difficult than that of ordinary colleges and universities in science. In addition, the medical bachelor’s degree usually goes to a hospital after graduation, and the development prospects in hospitals are also much better than that of ordinary colleges and universities. Therefore, the medical bachelor’s degree has a high gold content.

Who is the father of cardiac surgery?

Clarence Walton Li Lahai. Clarence Walton “Walter” Lillehei (ClarenceWaltonWaltLillehei, October 23, 1918 – July 5, 1999) was an American surgeon, one of the pioneers of open heart surgery, known as “the father of open heart surgery” and “the king of the heart”. He also created many technologies, devices and prostheses related to thoracic surgery. Clarence Lillehei (often referred to as “Walter”) was born in Minneapolis, Minnesota, USA. His father, Clarence Lillehei, was a dentist, and his mother, Elizabeth Lillehei. He received five degrees from the University of Minnesota, including a Bachelor of Science with honors in 1939, a Doctor of Medicine in 1942 and AlphaOmegaAlpha, the highest honor for medical students in the United States, a Master of Science in Physiology in 1951, and a Doctor of Philosophy in Surgery in the same year. Li Lahai was a professor in the Department of Surgery at the University of Minnesota from 1951 to 1967, during which he participated in the world’s first open-heart surgery using hypothermia. In 1944, Alfred Blelock of Johns Hopkins University successfully performed surgery on the large blood vessels around the heart, effectively relieving the symptoms of tetralogy of Fallot. This also marked the possibility of cardiac surgery that had previously been considered off-limits. Then on September 2, 1952, Dr. Floyd John Lewis successfully performed the first open-heart surgery using hypothermia, which became the world’s first successful cardiac surgical repair. Li Lahai, who was only 35 years old at the time, was a long-time friend and colleague of Lewis and also participated in the operation. However, the hypothermia method requires the operation time to not exceed 10 minutes, so it is very limited and does not apply to complex congenital heart defects. Li Lahai then developed the operation using the cross-circulation method to complete the operation. During the operation, the blood circulation of the patient’s heart is cut off, and a healthy person acts as a donor to provide the patient with normal blood circulation and tissue oxygen from his healthy heart next to the surgical patient. On March 26, 1954, he used this method to successfully perform surgery on a 13-month-old baby, Gregory Glidden, using the child’s father as a donor to successfully repair the patient’s ventricular diaphragm defect. The surgical repair itself was very successful, but the child died of a lung infection 11 days after surgery. The following year, Li Lahai and his team continued to use cross-circulation methods to perform open-heart surgery on more than 40 patients, most of whom were infants under the age of 2. A total of 32 patients survived. These surgeries included the first atrioventricular canal repair and the first tetralogy of Fallot repair. In 1958, Li Lahai also facilitated the clinical use of the world’s first small, external portable battery-powered pacemaker. This pacemaker was invented by Earl Bakken at Li Lahai’s will, just after Bakken and his partner co-founded the then small Medtronic Corporation, which was responsible for designing and repairing medical instruments for the University of Minnesota Hospital. In 1961, Albert Starr (Albert Starr) and Lowell Edwards (Lowell Edwards) jointly invented the Starr-Edwards artificial heart valve into the market, becoming the first replaceable artificial valve in history, and then Lilahai developed a number of design improvements for this invention, including Lilahai – Najib annular disc (theLillehei-Nakibtoroidaldisc, 1966), Lilahai – Custer rotating disc (theLillehei-Kasterpivotingdisc, 1967), Kalk – Lilahai rigid bilobular prosthesis (theKalke-Lilleheirigidbileafletprosthesis, 1968). Leerahai also dedicated himself to medical education, training more than 150 cardiac surgeons in 40 countries, including two of the four pioneers of heart transplantation: Norman Shumway and Christian Barnard (the others were Richard Lower and Adrian Kantrowitz). From 1966 to 1967, Leerahai served as dean of the American College of Cardiology (AmericanCollegeofCardiology). From 1967 to 1974, he also served as dean of the Cornell University School of Medicine in New York. In 1975, Leerahai returned to St. Paul, Minnesota, and became St. Jude Medical Company. Director of Medical Affairs at JudeMedical and also served as a Clinical Professor in the Department of Surgery at the University of Minnesota. The Heart Institute at the University of Minnesota is also named the “Lilahai Heart Institute” (LilleheiHeartInstitute) after him. Lilahai was awarded the Bronze Star Medal of the U.S. Army for his service in Italy during World War II. He also received the Lasker Prize for Clinical Medical Research in 1955 and the Hektoen Gold Medal from the American Medical Association in 1957. In 1963, Lilahai was awarded the Canadian Gairdner International Prize, and later in 1986 he was nominated for the Nobel Prize in Physiology or Medicine. He was inducted into the Minnesota Inventors Hall of Fame (MinnesotaInventorsHallofFame) in 1993. He also received the Harvey Prize for Science and Technology in 1996.
