In recent years, medical imaging technology has been changing with each passing day. However, relying on the pathological diagnosis of "human eyes" is still the "gold standard" for qualitative tumors. According to statistics from the Municipal Center for Disease Control and Prevention, there are nearly 50,000 new cases of tumors each year in Shencheng City, and the number in China is as high as 1.6 million. With the increase in patients, the need for pathological diagnosis has also risen. Data show that the Cancer Hospital conducts routine pathological diagnosis more than 30,000 cases, more than 30,000 cases of pathological consultations, more than 10,000 cases of frozen section diagnosis, and more than 50,000 cases of pathological diagnosis. As a leader with a large workload, the Department of Pathology at the Cancer Hospital could have been “safe and comfortableâ€, but why should they ask for food?
The embarrassment encountered in many international cooperation is an incentive. Professor Du Xiang, the director of the department, admitted frankly, “Some two or three times, foreign well-known universities and advanced laboratories proposed cooperation with us, and asked if there is any qualification certification to provide, we suddenly got a shell.†In addition, the Department of Pathology Although There are abundant experiences, but the manual operation is not accurate and standardized, and the original model is not in line with the currently advocated individualized therapy concept of cancer.
From experience judgment to precise management, changing the concept is not easy. Within two years of applying for accreditation, the Department of Pathology has newly prepared more than 100 documents, revised more than 400 different types of operating procedures, and filled out about 50 forms each day. To regulate the precise practice, it really worked well. At present, the department's intraoperative diagnostic rate of pathological diagnosis of 98%, conventional pathological diagnosis accuracy rate of nearly 99%, pathological diagnosis of "eye-catching", can be described as not bad.
Pathological diagnosis has authoritative approval, which facilitates the patient's international referral. Ms. Sun’s father suffered from esophageal cancer and had wanted to turn to friends abroad for treatment. “With CNAS accreditation, there is no need to repeat the examination and diagnosis abroad, which can save us a lot of money.†In addition, pathological diagnosis is all scientific data and research. The cornerstone of the results, with authoritative approval, the research of Chinese medical scientists in international related fields will be more convincing and have more say. Industry sources also stated that at present, the level of pathological diagnosis at medical institutions at all levels is uneven, and the introduction of standard qualification recognition will be a way to improve quality and improve levels.
Freeze-drying powder process includes: fresh fruit selection - cleaning - cutting - blanching - cooling - drying - grinding beating - gel grinding - sterilization - pre-freezing - vacuum freeze-drying - ultra-fine grinding - weighing packaging - testing - finished product.
Firstly, fresh and mature fruits with good quality were selected in the pre-treatment area of the food lyophilizer, and the leaves were removed to remove impurities. Then, preliminary cleaning and simultaneous sterilization of fruit surface were carried out. After sterilization, the fruits were cleaned and drained again. After the drain, the fruit is sliced and treated by blanching process. After the color preservation, the fruit is treated by pulping, and then pasteurized. The pretreatment process is finished before lyophilization.
The processing core of freeze-drying powder is the equipment area of food freeze-drying machine. After pre-treatment, the fruit enters the equipment of food freeze-drying machine and crystallizes into a solid state at low temperature, and then sublimates and dries in a vacuum environment to obtain freeze-drying products with little water content. Freeze-dried products out of the warehouse into the food freeze-dried post-processing area, ultrafine grinding, and then according to the need to do weighing packaging, after testing the finished products packed into storage.
