Herpes Zoster (HZ), also known as Acute Herpes Zoster (AHZ), is an acute herpetic disease involving nerves and skin caused by varicella-zoster virus (VZV) infection, and is one of the common and frequent diseases in dermatology. It can occur at any age, but is prevalent in the elderly and frail. Herpes zoster can occur on any part of the body, but is more common on the lateral chest and abdomen, and is mostly unilateral. It is characterized by clusters of small blisters on one side of the body, arranged in bands along the peripheral nerves, and accompanied by severe local pain. The rash occurs in the distribution areas of the intercostal nerve (53%), cervical nerve (20%), trigeminal nerve (15%) and lumbosacral nerve (11%). After a few days, the blisters dry up, crust and fall off, often accompanied by local lymph node enlargement. The onset of the disease is rapid, and the general course of the disease is about 2 to 3 weeks in children and young people, and about 3 to 4 weeks in the elderly. The disease can develop throughout the year, especially in spring and autumn, and rarely recurs after recovery, with a recurrence rate of 0.2% or less. The rash is often named according to its distribution characteristics, such as herpes zoster, herpes zoster, herpes zoster, herpes zoster, herpes zoster, herpes zoster, herpes zoster, herpes zoster, herpes zoster, herpes zoster, herpes zoster, etc. According to the degree of lesion, it can be divided into general, strophic, herpetic, hemorrhagic, gangrenous and generalized herpes zoster types. The name of the disease varies because of the different perspectives on the disease. The disease is called “snake sore” or “snake sore” because it “looks like a snake walking”; It is also known as “waist-wrapping fire-dan”, “waist-wrapping snake”, “waist-wrapping dragon”, “waist-wrapping dragon”, and “waist-wrapping dragon”. It is also known as “waist-wrapping sores”, “waist-wrapping snakes”, “waist-wrapping dragons”, “waist-wrapping dragons”, “waist-wrapping sores”, “waist-wrapping sores”, “jade belt sores”, and “cauldron sores”. The sores are called “white snake sores”, “snake sores”, “snake sores”, “spider sores” or “It is also known as “bottle belt sore” or “fire belt sore” because it is “like a bottle belt”. At present, it is commonly known in the north as waist-wrapping dragon and in the south as waist-wrapping snake dan. This disease has been discussed in medical literature throughout the ages, and a large number of treatment prescriptions have been recorded. The most representative of these is the book “The Golden Guide to Surgery”, which states: “This evidence is commonly known as snake sores, with dry and wet differences, red and yellow differences, all like tired beads. The dry ones are red and red in color, shaped like clouds, with wind and corn on them, making itchy and hot, and this belongs to the wind and fire of the liver and heart, and the treatment is appropriate for gentian diarrhea of the liver soup; the wet ones are yellow and white in color, with blisters of different sizes, making rotten water and more pain than the dry ones, and this belongs to the damp heat of the spleen and lung, and the treatment is appropriate for removing dampness and stomach lingering soup. If the waist and ribs are born, it is the liver fire delusions, it is appropriate to use Chai Hu Qing Liver Tang to treat the small blisters in between, pierced with a thread needle, the external use of cypress leaf powder.” The discussion is concise and concise, and the treatment formula is still in clinical use today. The clinical manifestations of the disease are described in detail in the “Dacheng of Surgery”, which states that the disease is “born on the waist, commonly known as snake bunches, and the sores are different in wet and dry, red and white, all like tired pearls. The dry ones are red in color, shaped like clouds, with wind corn on them, making itchy and hot. The wet ones are white like bubbles, varying in size, making rotten water, and more painful than the dry ones. Spider sores are born on the skin, shaped like water nests, with a light red and painful color, and are gathered in groups of three or two, just like spiders.” The disease is caused by varicella-zoster virus (VZV), which belongs to the alpha herpesvirus subfamily of the DNA herpesvirus (Herpes virus) family and has pro-neural and cutaneous properties. No pathogenicity has been found in animals other than humans. It proliferates in human or monkey fibroblasts and slowly produces cytopathic lesions, forming multinucleated giant cells with eosinophilic inclusion bodies visible in the nuclei of infected cells. It is weakly resistant in the outside world, heat- and acid-intolerant, sensitive to ether, and does not survive in the scab. Varicella-zoster virus (VZV) can cause two diseases: chickenpox and herpes zoster. Herpes zoster is a recurrent VZV infection that is latent in the body. Because VZV is neurophilic, after infection with VZV during childhood, the virus enters the sensory nerve endings of the skin, moves along the nerve fibers in the spinal column toward the center, and lurks in the nerve cells of the posterior root ganglion of the spinal cord or the infected ganglion of the brain for a long period of time, and normally does not cause disease, but when the body is exposed to certain triggering factors, such as fever, cold, mechanical pressure, excessive fatigue, mental trauma, bacterial infection, use of immunosuppressive agents, X-ray exposure, leukemia, and other diseases, it can cause herpes zoster. However, when the body is exposed to certain triggering factors, such as heat, cold, mechanical stress, overexertion, mental trauma, bacterial infection, use of immunosuppressive agents, X-ray irradiation, leukemia and malignant tumors, and organic disease attacks, resulting in impaired or low immune function of human cells, the latent virus activates and replicates, and proliferates in the skin cells innervated by the sensory nerve from one or several ganglia down the axon of the nerve, causing recurrent infection and a series of band-like blisters along the pathway of the sensory nerve on the skin, and the virus can cause The virus causes inflammation and necrosis in the affected ganglia, stimulating the sensory nerve centers in the cerebral cortex and producing severe neuralgia with localized nociceptive sensitivity within 1 to 4 weeks. In addition, the virus can also invade the visceral nerve fibers of the autonomic nerves from the posterior spinal roots and produce the corresponding symptoms.
