6. Ankylosing spondylitis (ankylosing
spondylitis; AS It is a kind of chronic progressive inflammatory disease which mainly invades the spine and can involve sacroiliac joint and peripheral joint in varying degrees. The disease is also known as Marie str ü Mpell's disease, von
Bechterew's disease, rheumatoid spondylitis, deformed spondylitis, rheumatoid central type, etc. are now called as. As is characterized by inflammation and ossification of the lumbar, cervical, thoracic spinal joints and ligaments as well as sacroiliac joints. The hip joint is often involved, and other peripheral joints may also have inflammation. This disease is generally negative for rheumatoid factor, so it belongs to seronegative spondylosis with Reiter syndrome, psoriasis arthritis, enteropathic arthritis, etc
ankylosing spondylitis is actually a very old disease. Evidence of ankylosing spondylitis was found in the bones of ancient Egyptians thousands of years ago. Two thousand years ago, Hippocrates, a famous Greek doctor, described a disease in which patients had pain in the sacrum, spine and cervical spine
in 1893, the disease was first described in detail by Russian btchterev. In 1897 and 1898, strumpell and Marie reported the disease in detail respectively, so they named it as berteleev's disease and Ma Shi Er's disease. In the Yellow Emperor's Canon of internal medicine (Suwen · Bi Lun Pian) more than 2000 years ago, it was recorded that "those with kidney Bi are good at distension, Jiji takes the place of heel, and Jiji takes the place of head", describing the pathogenesis and symptoms of the disease. This disease has been called rheumatoid spondylitis or central rheumatoid arthritis in China since 1950s. In recent years, with the development of medicine, the understanding of this disease has been deepened. It is found that this disease is different from rheumatoid arthritis in terms of age, sex, location, pathological characteristics and various laboratory tests, There is no rheumatoid factor in the serum of patients with ankylosing spondylitis, but the positive rate of HLA-B27 is very high, which indicates that the disease is completely different from rheumatoid arthritis. So in 1963, the international anti rheumatism alliance named the disease as ankylosing spondylitis
in 1982, the first Chinese rheumatism Symposium affirmed the international unified nomenclature of ankylosing spondylitis. The diagnostic names of rheumatoid spondylitis and central rheumatoid arthritis have been discontinued. In the latest classification of rheumatism, it has been classified as seronegative spondyloarthropathy. But at present, some domestic experts believe that this name is not very accurate, because the involved tissues and organs are not limited to the spine, hip, knee, ankle, wrist, shoulder and other limb joints can be involved, and the eyes, heart, lung, kidney and other organs are often involved, which should be a systemic disease, but this diagnostic name is still commonly used at home and abroad.

7. We've got people pushing potent drugs. It can save cement and cost

in my opinion, there are quite a lot of advertisements in the instry. It was also in an instry meeting. The video they played was a little interesting. I left a business card. Unexpectedly, I sent two bottles of samples to me and tried them. It was not bad. It saved 20kg of cement. The strength in 7 days was almost the same as the benchmark, but the later strength soon caught up with it, which was 3-4mpa higher. It has good workability, and the data of slump loss are ideal

I've also tried CTF's procts. If the effect does not last forever, the most hateful thing is that the quotation is confusing. If you don't bargain with them, they will certainly pit you
BTC seems to be a functional additive. Now its main business has been transferred to water recer. I don't know the effect of the proct. We haven't heard of anyone selling it here.
