已知实数a,b,有下列结论:(1)a=1,b=1,则根号ab≤1; (2)a=2分之1,b=5分之2,则根号ab≤9分之20(3)a=2,b=3,则根号ab≤2分之5;(4)a=1,b=5,则根号ab≤3.根据以上计算提供的信息,请猜想a,b与根号ab的关
a+b>=2根号下ab
因为a^2+b^2>=2ab
a=9,b=10时,根号下ab

猜想 (a+b )/2 >= 根号(ab)
根号(ab) <= (9+10)/2 = 19/2

The treatment of gastroesophageal reflux disease overview


Now that is mainly due to the esophagus and gastrointestinal motility disorder, because the esophagus to the stomach and duodenal contents reflux and reflux down the defense mechanisms of the esophageal mucosa matter the result of the attacks increased, which is the next most important esophageal sphincter (LES) pressure drop. Therefore, its treatment principles include ① reduce or eliminate symptoms; ② prevention of recurrence; ③ prevention and treatment of serious complications. I general treatment, including lifestyle and eating habits change, raise the bed to reduce nighttime reflux, low fat, low sugar diet, quit smoking wine, to avoid satiation, limit spicy food and so on. 2 acid-suppressing drugs, including H, receptor antagonists and proton pump inhibitors, the former through a competitive H2 receptor on the parietal cells to inhibit acid secretion, reducing gastric acid secretion, thereby reducing the acid on the esophageal mucosa injury, drugs, including West for D, ranitidine and so on. Proton pump inhibitors for the wall membrane of a proton pump H a K ATP inhibitor, can effectively inhibit gastric acid secretion lasting. H2 blocker maintenance therapy as effective as proton pump inhibitors. Author: 054001 Hebei Province, soldiers honor 3 prokinetic drug rehabilitation hospital of these drugs increase the esophageal motility, esophageal mucus secretion. ① metoclopramide include: dopamine receptor antagonists, the LES pressure increases, preventing the stomach, duodenum fluid reflux, but it is through blood-brain barrier, causing the central nervous system side effects. Such as insomnia, tremor, movement disorders. Not long-term use; ② domperidone: Peripheral dopamine receptor antagonist, increased LES can promote esophageal motility,Links of London Charms, nausea and vomiting symptoms are particularly effective, side effects can cause high lactation hyperlipidemia cable, such as galactorrhea, breast enlargement, etc. ; ③ 5 a HT4 receptor agonists, cisapride, mosapride, acting on the myenteric plexus to ask the release of acetylcholine, the increase in lower esophageal sphincter pressure, esophageal peristalsis strengthened, accelerated gastric emptying, attention is not with large ring lactone antibiotics, antifungal agents combined, and the other can cause QT interval prolongation, heart disease patients with caution. 4 mucosal protective agent mucosal protective agent for patients with esophagitis, may consider the application. Including sucralfate, cover the stomach flat, well close up, bismuth preparations, sucralfate which can reduce the symptoms and treatment of reflux esophagitis may be sucralfate and ulcer, erosive surface positively charged protein binding, Live + charge in forming a barrier to prevent mucous membrane is digested, can cover the stomach and saliva levels, gastric juice works, forming a layer floating in the viscous glue tour. 5 Surgical treatment Surgical treatment of reflux esophagitis on esophageal stenosis when combined,timberland shoes, can be considered for endoscopic dilation. Tips for endoscopy in patients with Barrett's esophagus, endoscopic suturing can be used or added anti-reflux fundoplication surgery. Currently,vibram five fingers singapore, the majority of gastroesophageal reflux disease need medical treatment. Application mainly mucosal protective agent, acid-suppressing agents and prokinetic drugs, of which the best efficacy of proton pump. Elbow joint nerve disease in 1 case Liubao Xun Xie Hongfeng Han Fusheng Yang Qijun Xiegang Long patient,GHD gl?tteisen, female, 55 years old. Due cervical syringomyelia 1O years, a fall two weeks left elbow swelling with fever 1 day hospitalization. Physical examination: T39 ℃, no abnormal cardiopulmonary abdomen, right convex thoracic spine, thoracic asymmetry. His hands were claw deformity, left elbow was swollen, red skin, skin temperature high, no tenderness, palpable sense of volatility,belstaff outlet, the left elbow against Zhang, both upper limbs was significantly decreased pain and temperature sensation of skin to the ulnar to the double upper limbs Ⅳ, increased muscle tone, brachial two triceps hyperreflexia, Hoffman's sign (+), trunk from the nipple pain and temperature sensation below the level of decline. Lower limb muscle strength grade Ⅳ, increased muscle tone, knee tendon reflex and Achilles tendon hyperreflexia, ankle clonus patellar (+), bilateral Babinski'S sign (+). X ray showed dislocation of the elbow joint, bone-side frosted glass-like changes in intra-articular loose bodies, soft tissue swelling. Diagnosis: cervical syringomyelia, left Author: 065,300 Dachang Hui Autonomous County, Hebei Province People's Hospital, Case Report elbow joint nerve disease complicated by infection. Line elbow puncture, pus out about 400ml of liquid, bad taste. The E. coli bacterial culture on Cyprus oxime cephalosporin sodium sensitive, the anti-infection and improved and discharged after the joint incision and drainage. Discussion of joint disease, also known as Chareot nerve or neuropathic joint arthritis, 25% of the relevant section of the spinal cord lesions of patients with syringomyelia 【l0J. The disease is characterized by pain, joint dysfunction and damage is not proportional. Treatment to remove the cause of treatment mainly due to disease in patients with syringomyelia to conservative therapy.
