Dry syndrome is a chronic inflammatory autoimmune disease mainly invading salivary and lacrimal glands, and the details noted in daily life are very important. 1.Keep a happy mood, follow the doctor’s advice and review regularly. 2, diet: eat more nourishing and clearing foods that generate heat and fluid, including loofah,, celery, yellow cauliflower, lotus root and yam, etc. Avoid spicy, fried, too salty and too acidic foods, and the usual nutrients should not be too strictly restricted. 3, as far as possible to avoid the use of drugs: can make the exocrine glands to reduce the secretion of drugs causing dry mouth include: anticholinergics; anti-hypertensives: alpha-blockers (colistin), beta-blockers (insulin, compound beta-blockers); diuretics; antidepressants: amitriptyline, norethindrone amitriptyline, etc., myasthenic drugs: aminophenyl cycloheptene, methocarbamol, urological drugs: ura choline, hydroxybutynin Cardiac drugs: diisobenzylpyrimethamine phosphate, Parkinson’s drugs: carbidopa, levodopa, decongestants: paracetamol, levoephedrine, etc. 4, pay attention to oral hygiene: dry mouth, little saliva, dental caries and tongue chap should pay attention to oral hygiene, prevent the proliferation of oral bacteria, brush teeth at least 2 times a day in the morning and evening, use soft-haired toothbrush is appropriate, rinse mouth after meals, avoid smoking and alcohol, reduce the stimulation of physical factors, secondary oral infection can be used to rinse mouth with Dobell’s liquid, have dental caries should be repaired in a timely manner, weekdays with maitake, sage and licorice and other traditional Chinese medicine to make water for tea to keep the mouth moist For those who have oral candida infection, mycobacterium can be used. Drink water or use artificial saliva, chew sugar-free chewing gum (xylitol) frequently, and there is a series of “Baiosu” products which have good effect on maintaining oral hygiene. Oral drugs are cyclopentethione (Shua Le, bile vita): 15-30mg/day, the recent new drugs are Evoxac (chemical name cevimeline, cevimeline) for dry mouth and eyes (especially dry eyes) more effective, long half-life, longer duration of efficacy, sweating and abdominal pain and other side effects are small. 5, protect the eyes: less tears make the eyes dry, defense function is reduced, foreign body feeling, can cause corneal damage, prone to bacterial infection, vision loss and other eye diseases, should pay attention to prevent eye dryness, available artificial tears such as 1% methyl cellulose, hydroxymethyl cellulose or polyvinyl alcohol eye solution point eye, but the effect is short, and slow-release artificial tears or 0.1% hyaluronic acid eye solution [domestic have wetting Shu point eye solution ( hyaluronic acid + chloramphenicol)] is more effective, serious cases with 0.5%-2.0% cortisone eye drops, can quickly relieve symptoms, but easy to relapse after discontinuation, can not be used for a long time, in order to avoid corneal thinning perforation. Those with eye irritation use 2% acetylcysteine ophthalmic solution 3-4 times/day to break down pathological mucus strips. Wear diving goggles at night to prevent tear evaporation and apply eye ointment at bedtime to protect the cornea. Also 1% cyclosporine eye drops, 2-3 times/d, can significantly increase tear secretion. For those with corneal epithelial defects use Bevosol dot eye solution (alkaline fibroblast growth factor) to promote repair and regeneration, l-2 drops each time, 4-6 times a day, for no more than 2 weeks. For concomitant blepharitis, bacterial conjunctivitis, and corneal ulcers, antimicrobial eye drops such as tetracycline ophthalmic ointment can be used. In addition, tear point closure can also be performed to reduce tear drainage in the form of temporary closure with collagen plugs or permanent laser closure. 6, hypokalemic renal tubular acidosis: pay attention to long-term supplementation of 20% potassium citrate and baking soda to adjust the water and electrolyte balance. 7, mouth ulcers: gargle or drink as tea with honeysuckle, white chrysanthemum or umeboshi licorice soup, etc. 8, dry nasal cavity: use saline nose drops, do not use oily lubricant, so as not to cause lipid-like pneumonia by inhalation. 9, vaginal dryness: use lubricant, maintain vaginal hygiene, change underwear regularly.
