Herpes zoster is a neuropathic disease which induce by the varicella-herpes virus reactivation.and postherpetic neuralgia (PHN) is the most common complication. Currently,the mechanism of herpes zoster still unclearly even though there had much study about it .Vitamin D is an essential vitamin for human body, which has the function of maintaining calcium and phosphorus homeostasis and immune regulation. Vitamin D is a natural antiviral substance, and vitamin D deficiency can affect the body's antiviral ability, thereby promoting varicella-zoster virus(VZV) reactivation, and may promote the development of PHN through continuous neuroinflammation. Therefore, vitamin D level may be related to the occurrence and progression of HZ. this study intends to use an observational cohort study design to investigate the correlation of serum vitamin D level and osteoporosis degree with the severity of the herpes zoster disease, Although we plan to further explore the role of inflammatory state in this process.
1,287 studies on the registry are indexed under Neuralgia; 256 are open to participants now.

Time frame: Day 2 in the hospital
Blood glucose
The production and utilization of blood sugar in normal people are in a state of dynamic balance, maintaining a relatively stable level, which is because the source and route of blood sugar are roughly the same result.Fasting blood-glucose(FBG):4.4\~6.1mmol/L。
Time frame: Day 2 in the hospital
diastolic blood pressure,
An indicator in blood pressure measurement that indicates the pressure of the heart's arterial blood against the vessel walls during diastole. It is usually measured in millimeters of mercury (mmHg).
Time frame: Day 2 in the hospital
systolic blood pressure
A type of blood pressure that refers to the pressure of blood against the artery walls when the heart contracts. It is often used as a measure of cardiovascular health(mmHg).
Time frame: Day 2 in the hospital
total cholesterol
The sum of all cholesterol in the blood, including LDL cholesterol and HDL cholesterol. High levels of total cholesterol may increase the risk of cardiovascular disease.normal range：\<5.18mmol/L（\<200mg/dl）
Time frame: Day 2 in the hospital

Triglyceride (TG) is a constituent of lipids, which is formed by glycerol and three fatty acids. normal range\<1.70mmol/L.
Time frame: Day 2 in the hospital
serum Ca2+ level
Ionic calcium refers to the concentration of calcium ions in the blood, also known as serum calcium. Normal levels of ionic calcium maintain a stable range in the blood, generally 2.1-2.6 mmol/L(or 8.5-10.5 mg/dL).

Cellular immune indexes C3
Complement C3 can promote phagocytic cells to move to promote phagocytosis, promote B cell proliferation, and have a solubilization effect on soluble immune complex.
Time frame: Day 2 in the hospital
Cellular immune indexes C4
Complement C4 is an important component of the classical activation pathway of complement, which is divided into C4a and C4b. The release of C4a can induce mast cells to release histamine, increase the permeability of blood vessels and cause local exudative inflammation. C4b mainly plays a role in mediating the complement cascade, promoting phagocytosis, participating in preventing the deposition of immune complexes, and neutralizing viruses.
