Chest tightness and difficulty in whistling are the most common symptoms of pulmonary fibrosis and one of the most difficult for the human body to accept. People learn to whistle with their lungs from the moment they are born, but pulmonary fibrosis seriously affects the whistling function of the lungs, which makes it unbearable no matter what. Pulmonary fibrosis mostly develops between the ages of 40 and 50, more in men than in women, and more in smokers than in non-smokers. This pulmonary fibrosis should be considered a disease of the middle-aged and elderly, because it is prevalent mainly in the middle-aged and elderly groups. We not only ask why this pulmonary fibrosis favors the middle and old age group so much? In fact, when it comes to the reason, it is also very simple, the middle-aged and elderly group is older, poorer, more problems! We can briefly summarize. First, because of the middle-aged and elderly groups of their own immunity is low, vulnerable to the influence of the external adverse environment. With the growth of age, the various organs of the human body will slowly appear the phenomenon of failure, in this process, organ function is greatly affected, so the ability to resist disease will be greatly reduced, then naturally there will be a higher incidence of some diseases than the age of people, including this pulmonary fibrosis. Second, the main cause of pulmonary fibrosis is smoking, and middle-aged and older men are the main group of smoking, even if they do not smoke, then the time affected by second-hand smoke environment will be significantly higher than young people. This is determined by the age factor, they are exposed to tobacco, longer than young people, but also longer than women of the same age. The kidneys are located deeper and are well protected by the psoas muscle, vertebrae, ribs and abdominal organs and are generally not easily injured. Only when the violence directly injured the kidney area or the kidney itself has a lesion is prone to injury. Kidney injuries are mostly seen in adult males. Treatment of kidney injury generally includes the following aspects: 1, to prevent shock: for severe kidney injury, serious blood loss, should be closely observed changes in the condition, early transfusion and rehydration to maintain water, electrolyte balance, pain relief, warmth, maintain adequate urine volume, etc., to prevent the occurrence of shock. 2, non-surgical treatment: suitable for closed mild kidney injury, bleeding is not serious, no shock symptoms, about 80% of patients can be cured through non-surgical treatment. Treatment includes: (1) absolute bed rest for at least 2 weeks, closely monitor blood pressure, pulse, inspiration, body temperature, etc. (2) Replenish blood loss and give hemostatic drugs. (3) Analgesics may be applied after the diagnosis is clear and other organ injuries such as chest and abdomen are excluded to avoid masking symptoms and changes in condition. (4) Give antibacterial agents to prevent secondary infection. (5) Urine colorimetric measurement: take a part of the specimen for each urination and place it in a transparent tube for colorimetric comparison, and pay attention to the changes of hemoglobin until the bleeding stops and the condition is stable. 3.Surgical treatment: Suitable for open and severe kidney injury, with other visceral organ injury or by non-surgical treatment continues to deteriorate and shock is not easily corrected, often need emergency surgery. Pre-operative understanding of the contralateral kidney function, surgery to maximize the preservation of kidney tissue. Surgical methods include: (1) lumbar incision and perinephric drainage: suitable for severe urinary extravasation or complicated perinephric infection. Removal of hematoma and foreign body, control of bleeding, repair of injured kidney and perirenal drainage. (2) Renal repair and partial nephrectomy: renal laceration can be repaired with sutures or a part of the kidney can be removed with severe injury. (3) Nephrectomy: if the kidney bleeding is uncontrollable, the kidney is severely fragmented or the nephron is broken beyond repair, and the contralateral kidney is functioning well, nephrectomy can be performed. (4) In the case of isolated kidney or severely impaired contralateral kidney function, when the ruptured kidney needs to be preserved, absorbable thread mesh bag is applied to wrap the kidney. Third, the middle-aged and elderly groups suffering from chronic bronchitis and other lung diseases are also significantly higher than young people, it is important to know that these chronic bronchial and other lung diseases are the main cause of pulmonary fibrosis is the main cause. Some middle-aged and elderly people may have had bronchitis for many years, and it is not uncommon for pulmonary fibrosis to occur at this age. Fourth, the middle-aged and elderly, due to the age factor, they are exposed to adverse environmental influences for a much longer period of time than young people, while the body’s ability to resist disease, but significantly less than young people, then naturally more prone to disease.
