What are the main contents of the rejection reaction of the corneas?
Corneal transplant rejection mainly included the following: ** I. Relationship between the type of corneal-transplant and rejection ** 1. ** Transplantation Type Description ** - There were three types of organ transplants: autotransplantation, allotransplantation, and xenogeneic transplantation. Among them, there would be no immune rejection in an autotransplant because the transplant was taken from the recipient. Allogeneic transplantation was a transplant between individuals with different genes within the same species. Generally, there would be a transplant immune rejection reaction. Xenogeneic transplantation was a transplantation between different species. Due to the huge genetic background differences between xenogeneic animals, serious immune rejection would occur. Corneal transplantation was a type of allotransplantation. Allogeneic organ transplantation was common, but there were side effects of rejection, which limited the long-term survival of organ transplantation. 2. ** The Speciality of Corneal Transplantation ** - Among all the organ transplants, corneas were considered to have the highest success rate. Compared with other tissues, the corneas had the characteristic of being relatively immune to foreign transplanted tissues or other antigen-stimulated tissues. It was called an immune privileged tissue. However, in recent years, studies have found that the corneas have a complex immune system. In clinical cases, the state of the corneas is often destroyed by high-risk factors, resulting in an increased rate of rejection. ** II. The influencing factors of corneal-transplant rejection ** 1. ** Donor and recipient factors ** - One of the factors that led to rejection was the difference in tissue compatibility between the donor and the recipient. For example, the Human Leucoid Antigen Class I will stimulate the body to produce a series of toxic cells, which will attack the target cells and cause rejection. 2. ** Corneal condition related factors ** - The formation of new blood vessels would lead to rejection. The rejection rate of lamella keratotransplantation for keratopathic diseases without neovessels was generally only 4% to 5%, and the rejection rate of penetrating keratotransplantation was less than 10%, while the rejection rate of keratopathic diseases with severe neovessels could be as high as 20% to 50%, or even 75%. Corneal chemical injury, explosive injury combined surgery, and corneas with active inflammation had a significantly higher chance of rejection after the surgery. This was related to the increased number of new blood vessels in the corneas, the increase in the inflammation mediator in the front segment of the eye, and other complications after the surgery. The failure of multiple corneas transplantations was also an important factor leading to rejection. Multiple transplantations increased the number and types of transplant hormones, increased the degree of vasodification of the transplant bed, and further destroyed the normal physiological mechanism in the eye, thus significantly increasing the incidence of rejection. Corneal blindness was closely related to the occurrence of immune rejection after keratotransplantation. For example, chemical injury, explosive injury combined with surgery, active inflammation of the corneas, and other reasons caused the blindness of the corneas. The probability of rejection after the surgery increased. ** III. Corneal transplant rejection symptoms ** 1. ** Vision and Corneal Appearance ** - The patient may experience discomfort such as decreased vision and turbid corneas. Corneal transplantation may have oedema that does not subside for a long time. Grayish-white deposits may also appear after the transplantation. Because of the turbid corneas, the patient felt as if there was a layer of fog in front of his eyes when he saw something. 2. ** Different types of rejection symptoms ** - If it was a rejection of the corneas, it would be presented as edema of the corneas, if it was a rejection of the stroma, it would be presented as edema of the stroma, and if it was a rejection of the capillaries, it would be presented as edema of the capillaries. There may also be sudden tears, redness, foreign body sensation in the eye, blurred vision, obvious edema of the corneas, and other symptoms. ** IV. Ways to avoid rejection of corneas ** - Miech's artificial corneas are made of man-made materials It can help alleviate the scarcity of corneas in China, avoid rejection reactions, and improve the success rate of surgery. It has been approved for patients with corneas in both eyes who are difficult to succeed in corneas transplantation surgery, including corneas that have failed, chemical injuries, thermal burns, explosive injuries, and other serious corneas and collaterals, and eyelid atresia. severe autoimmunity diseases (such as Stevens-Johnson syndrome and cicatristic pemphigoid), end-stage dry eye, and so on.

How to calculate the duration of the career establishment to be a civil servant?
After the career establishment personnel were transferred to civil servants, their promotion would be calculated according to the number of years of service after the civil servant examination.
