What is SLE product of blockchain

1. digital currency can be considered as a virtual currency based on node network and digital encryption algorithm. The core characteristics of digital currency are mainly reflected in three aspects: first, e to some open algorithms, digital currency has no issuing subject, so no one or institution can control its issuing; ② Because the number of algorithm solutions is fixed, the total amount of digital currency is fixed, which fundamentally eliminates the possibility of inflation caused by the overuse of virtual currency; ③ Because the transaction process needs the approval of each node in the network, the transaction process of digital currency is safe enough [3]
the emergence of bitcoin poses a great challenge to the existing monetary system. Although it belongs to the generalized virtual currency, it is essentially different from the virtual currency issued by network enterprises, so it is called digital currency. This paper compares digital currency with electronic currency and virtual currency from the aspects of issuing subject, scope of application, issuing quantity, storage form, circulation mode, credit guarantee, transaction cost and transaction security [3]

according to the relationship between digital currency and real economy and real currency, they can be divided into three categories:
one is completely closed, has nothing to do with real economy and can only be used in specific virtual communities, such as world of warcraft gold
Second, it can be purchased in real currency but not converted back to real currency, which can be used to purchase virtual goods and services, such as Facebook credit
thirdly, it can be exchanged and redeemed with real currency according to a certain ratio. It can purchase both virtual goods and services and real goods and services, such as bitcoin [2]
transaction mode
at this stage, digital currency is more like an investment proct, because of the lack of a strong guarantee agency to maintain its price stability, its role as a value measure has not yet appeared, and it can not be used as a means of payment. As an investment proct, digital currency cannot develop without trading platform, operating company and investors [4]
trading platforms act as trading agents, and some of them act as market makers. The profits of these trading platforms come from investors' transaction or withdrawal fees and premium income from holding digital currency. Bitstamp, gathub, ripple Singapore, snapswap, Japan's Mt. GOx and China's new star Ruihu are the platforms with large trading volume [4]
the process of digital currency trading through the platform is as follows:
(1) investors should first register their accounts and obtain digital currency accounts and US dollar or other foreign exchange accounts
(2) users can buy and sell digital currency with the money in their cash account, just like buying and selling stocks and futures
(3) the trading platform will sort the buy requests and sell requests according to the rules and start to match them. If they meet the requirements, the transaction will be concluded
(4) a buy or sell request may be partially executed e to the difference between the buy and sell volumes submitted by users
the transaction mode of digital currency through operating companies is as follows: take Ruibo coin as an example, Ruibo coin is operated by professional operating company opencoin, ripple protocol was originally designed based on means of payment, and the design idea is based on acquaintance network and trust chain. To use ripple network for remittance or loan, the premise is that in the network, the payee and the payer must be friends (mutual trust relationship is established), or have common friends (trust chain is formed through the transmission of friends), otherwise the trust chain cannot be established between the user and other users, and the transfer cannot be carried out [4].

2. Systemic lupus erythematosus (SLE) is a kind of autoimmune disease. Its pathogenesis is related to family heredity, ultraviolet radiation, estrogen level, some drugs, food and infection< After the onset of lupus erythematosus, we should pay attention to the following ten issues:

first, pay attention to recuperation, maintain a positive and optimistic attitude
Second, pay attention to the combination of work and rest, exercise properly, and control sexual life
Third, pay attention to the prevention of colds, and actively prevent and treat various infections
Fourth, pay attention to avoid direct skin exposure to the sun
fifth, pay attention to smoking cessation and alcohol abstinence
sixth Some western medicine can often cause or aggravate the disease, so pay attention to avoid using it.
7. Pay attention to some health procts that are not beneficial to SLE patients, but harmful to them.
8. Pay attention to avoid using drugs and foods containing estrogen.
9. Pay attention not to eat mutton, dog, horse, deer, donkey meat.
10. Pay attention to supplement high-quality protein and vitamins, and eat less high-fat, high-fat, high-fat, low-fat, low-fat, low-fat, low-fat, low-fat, low-fat, low-fat, low High cholesterol food

3. A kind of contact IC card, Siemens 4442. 1、 Main indicators: ● 32-bit protection memory; 256 byte EEPROM; 3-byte user password, password error count: 3 times; Temperature range: 0 ℃ ~ 70 ℃; At least 100000 erasures; At least 10 years of data storage. Working voltage: 5V. 2、 Security features: 1. Each byte of the write protection area (the first 32 bytes) can be written separately. After the write protection, the content cannot be changed (that is, the data can be solidified). 2. Before the password is checked correctly, all data can be read. If necessary, the data can be properly encrypted. 3. After checking the correct password, it can be written or modified. 4. The three byte user password can be changed after checking it correctly until the card is powered off. 5. If the counter value is 0, the card will be locked automatically, and the data can only be read out, and can not be changed, nor can the password be checked again; If it is not zero, once the password is checked correctly, it can be restored to the initial value. 6. Byte address 21-26 is the user code. Our company can set a unique global code here for large users, so that users can issue and use it uniformly (all cards can't be modified after leaving the factory). 7. Byte addresses 0-5, 6-7 have been written by the manufacturer before leaving the factory and cannot be changed. 3、 Note that the password area is separately addressed, which is not within 0-256 bytes.

4. Systemic lupus erythematosus. It is a disease of multiple system damage caused by antibody and immune complex deposition and complement fixation. It is an autoimmune disease. Its clinical manifestations are complex. It is characterized by deterioration and uncertain remission. The pathogenic immune response may be caused by the action of some sensitive genes by environmental elicitors. At present, ultraviolet rays and some impurities are more certain. The main symptoms are: facial erythema, rash, joint pain, light sensitivity, fever, dizziness, headache, fatigue and other initial symptoms.

5. Diffuse connective tissue disease (CTD), once known as collagen angiopathy, is a group of chronic inflammatory autoimmune diseases involving multiple systems, including systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), Sjogren's syndrome (SS), systemic sclerosis (SSC), polymyositis / dermatomyositis (PM / DM), vasculitis (nolar polyarteritis, Wegener granuloma, Takayasu arteritis, etc.), The main pathological changes were chronic inflammatory changes of target tissues and blood vessels and fibroid degeneration and hyperplasia of collagen tissue

6. Understanding the following points is very helpful for self judgment:
1. Under normal circumstances, if the patient is more prone to fatigue than usual and has no obvious improvement after rest, he should think of the possibility of disease activity
2. Pain and swelling of joints (such as proximal interphalangeal joint, wrist joint, knee joint, ankle joint, etc.) may be accompanied by morning stiffness or joint effusion
3. New rashes (such as buccal erythema, discoid erythema, chilblain like lesions, erythema multiforme like lesions, vasculitis skin lesions, perinail erythema, etc.) or aggravation of original rashes
4. Without upper respiratory tract infection, diarrhea, frequent urination, urgency and pain, fever of unknown origin or ESR of unknown origin increased significantly
5. New or frequent oral or nasal ulcers. New or frequent onset of plaque or diffuse alopecia
6. Pleurisy is the most common lung disease in SLE patients. Patients often complained of chest pain, aggravated by respiratory movement or postural changes. Pericarditis is the most common cardiac disease in SLE. The main manifestations are blunt pain in the posterior sternal or precordial area, or acute chest pain, which is aggravated by breathing, coughing or swallowing. Chest pain is relieved when the body leans forward. If the above situation occurs in the course of disease, should go to the doctor for examination
7. If white blood cells, platelets and hemoglobin are lower than normal level or urine protein and red blood cells appear in urine routine examination, we should consider whether there is disease activity
8. If the unexplained diarrhea, abdominal pain, nausea and vomiting are not improved after anti infection and symptomatic treatment, the presence of lupus gastrointestinal activity should be considered
9. If SLE patients have hallucination, delusion, sense of control and other thinking disorders, mental symptoms such as hypomania and depression, organic encephalopathy syndrome such as consciousness disorder, disorientation and incalculability, severe and persistent headache and convulsions, the central manifestations of SLE should be considered and early treatment should be given
in a word, it is a key link in the treatment strategy of SLE to comprehensively judge and understand the changes of one's condition, regularly go to the doctor for follow-up and cooperate with the doctor for active treatment.

7. Systemic lupus erythematosus (SLE): it is an autoimmune disease. Its pathogenesis is related to family heredity, ultraviolet radiation, estrogen level, certain drugs, food and infection.

9. Hello! Lupus erythematosus (SLE) is an autoimmune disease with unknown causes, multi system and multi organ damage; Lupus erythematosus most often involves skin, joint, kidney, brain, blood and other organs or systems. The etiology of lupus erythematosus is still unclear, which may be related to many factors, such as heredity, infection, hormone, environment, sunlight, drugs, pregnancy and so on
the clinical manifestations of lupus erythematosus include: facial butterfly erythema, joint pain, fever, alopecia, leukopenia, anemia, light sensitivity, mucosal damage, oral ulcer, etc. But not everyone has these symptoms, which vary from person to person, so it is necessary to carefully identify and quickly diagnose------ Immunology expert: Professor Zhang Dejing
