According to Xinhua News Agency, Shanghai Electric (Reporter Zhou Lin) used artificial intelligence for early screening of cancer, big data analysis of the possibility of cancer, completely paperless "full-process medical", and even VR (virtual reality) technology can also For medical imaging consultations... The reporter found at the China International Medical Equipment Fair held recently that unlike the previous ones, this year’s “China’s largest medical device exhibitionâ€, many manufacturers brought “black technology†Cross-border and integration, not only is not cold, but also can save money and save time for patients.
Artificial Intelligence: Medical "Alpha Dog" recognizes cancer
In the booth of the joint film medical reporter, the difference image technology, the chest images of the two lungs of the same person at different times of the computer automatically overlap, the artificial intelligence automatically recognizes the nodule position, and calculates the size and density of the nodules. Equal quantitative data for direct reference by doctors.
As we all know, the early diagnosis of cancer has a direct effect on the healing effect. The sooner you notice, the higher the cure rate. Based on the above-mentioned intelligent technology platform, seven hospitals including Changzheng Hospital jointly established the “Lung Cancer Case Database†to assist experts in screening normal populations. After more than 200,000 tests, more than 7,000 high-risk groups of lung cancer were discovered.
“If there is a light spot in the medical image of the lungs, an experienced doctor is needed to determine whether it is a nodule or a tumor. The next step is needed. How many humans are needed after hundreds of millions of people have been screened?†And CEO Xue Min said that this intelligent platform has now introduced artificial intelligence. The medical industry's "Alpha Dog" can diagnose lung cancer early through imaging through deep learning of the doctor's diagnosis process. The screening results of computers and experts are currently being compared. If the similarity is high, the computer may make independent judgments in the future.
This artificial intelligence system automatically and accurately identifies small-diameter lung nodules in the image, and is also self-optimizing based on big data to provide accurate medical care. In the future, we can use the big data to develop the first early warning standard for the high-risk population of early lung cancer in China.
Out of the "island": the patient tracked the whole process before the pre-hospital
“We are committed to creating an open, all-weather digital platform for medical management and care. All data from patients before the hospital can be connected through this platform to achieve true full-course medical care.†Philips Medical Information Solutions Greater China President Chen Shengyu said.
In the past, not only the medical treatment and imaging data between hospitals were “islandsâ€, but sometimes different departments of the same hospital were also difficult to be completely interconnected. Doctors who wanted to have consultations had to spend a lot of time on data update and handover. Post-operative follow-up and return visits after discharge from the patient are “basically on their ownâ€.
The reporter saw at the Philips booth, from pre-operative diagnosis, image-guided treatment, to the occurrence and treatment of accidents during surgery, and post-operative physical signs monitoring, etc., can be achieved on a digital platform. Moreover, this platform is also open, not only Philips' data, but other inspection data can be directly accessed to achieve complete interconnection of data.
Chen Shengyu said that through the sharing of data and the opening of the platform, the early stage of chronic disease management, through advanced physical signs monitoring, can alert and track the occurrence of diseases; in the event of an emergency, improve the ability of medical staff to develop optimal treatment plans for patients. Improve inspection, diagnosis, and decision-making outcomes; in post-hospital collaborative care, wearables can be used to directly monitor the patient's postoperative recovery status. “It’s the equivalent of liberating doctors from medical records and creating a “paperless†medical treatment.â€
VR help out: "cloud" diagnosis and treatment to break the grassroots bottleneck
In the booth of the joint film medical reporter, a pair of VR glasses can achieve remote consultation. After putting on the glasses, gently click on the screen, the three-dimensional image of the heart, nerves, etc. on the screen can be dynamically adjusted, the size direction can be adjusted freely, and the lesions and cross-sections can be viewed, so that the image can be "talked" remotely. Through this screen, the old doctor can Remotely instruct the new doctor to see the "key points" in the CT image.
This is only part of the “U+ Internet Strategy†of Lian Ying Medical. The reporter saw through the propaganda film that in the Jiading District of Shanghai, where the “Regional Imaging Center†was established, the community hospital took the CT, and the first time it was transferred to the second-level central hospital, the computer carried out all the films. Automatic sorting, professional image judgement personnel to diagnose according to the pain, emergency patients can get a diagnosis report in half an hour.
"This is like all patients at the grassroots level have opened a VIP green channel. They don't need to come over to register or wait, and they can directly produce the film." Xue Min said that residents in Jiading District can enjoy image-based equipment in community hospitals. Physical examination, pregnancy test, chronic disease follow-up, cardiovascular and other common diseases, geriatrics follow-up and related imaging diagnosis services, to achieve "small illnesses do not leave the community"; in district hospitals, residents can complete early diagnosis of tumors, Early treatment, to achieve "big illness does not have to leave the district."
The most difficult thing for a basic hospital is that there are no talents, no one can be recruited, and no one can stay. In particular, community health centers in remote areas have been dubbed as “brick-making factoriesâ€. Even if there are professionals coming over, they have been “building houses†for others for two years. With the "cloud" technology, the image center is equivalent to the "brain" to provide "brain support", the community center is equivalent to "hands and feet", only need to be equipped with a technician to operate the machine.
Xue Min said that in addition to Shanghai Jiading District, Lian Ying and Huada Gene started the construction of a precision medical big data center based on medical imaging data and genetic data, and built the first batch of “County Precision Medical Centers†in Guizhou. Insufficient medical resources at the grassroots level can double the accuracy of diagnosis and treatment, achieve "treatment without disease", and drive the disease from "governance" to "defense."

Plant extraction process
1. Select plants/medicinal materials. It is nothing more than ancient prescriptions, proven prescriptions, and folk medicinal herbs. At present, common and uncommon medicinal materials have been studied. Most of the time, the amount of medicinal materials has been increased to extract low-isolated components, or medicinal plants have not been studied from Miao medicine, Tibetan medicine, Mongolian medicine, Africa, Latin America and other places.
2. Extract. Solvent petroleum ether, n-hexane, cyclohexane, benzene, chloroform, ethyl acetate, n-butanol, acetone, ethanol, methanol, water (small polarity → large polarity). Daily decoction of medicines is effective, use water and ethanol and other solvents with high polarity. Artemisinin and other boiling methods are not effective, use petroleum ether and other solvents with low polarity. The common medicinal materials, water/alcohol/ether, are presented again, and more compounds can be separated and identified.
3. Separation. This is the most important task. There are dozens of compounds in the solution extracted in the second step. Generally, column chromatography is used, which is what we often call column flushing. The workload is large, boring, and low-tech. A master's degree may do this every day for 2 years of experimentation. As shown in the figure below, the column for separating compounds is as large as 2 meters high and as small as 10 cm. Change the solvent conditions of the mobile phase, change the material of the column, and repeatedly wash the column under different conditions and separation principles to separate the monomer compound.
