Release date: 2016-06-17 Ultrasound focused therapy has benefited many patients. The future direction of medical development will have two major trends: one is personalized treatment based on gene and stem cell technology, and the other is non-invasive treatment based on ultrasound focusing technology. This is the description of Stephen Sinfer, former dean of the University of Maryland Medical Center and dean of the National Institutes of Health Magnuson Medical Center, in his book Medical Megatrends: Tomorrow's Medical. In fact, as early as 2011, Time magazine magazine in the United States listed ultrasound focusing technology as one of the 50 most important inventions in the new century. Even Professor Crum, President of the International Society of Ultrasound, made the prediction that the 20th century is the golden age of ultrasound imaging development, and the 21st century will be the golden age for the development of ultrasound therapy. Selective damage to the lesion Ultrasound focusing technology originated in the 1940s and is a therapeutic technique that uses high-intensity ultrasound beams to focus in the body and selectively damage diseased tissue in the target area. The treatment principle is that ultrasonic waves are used as an energy source to emit low-dose ultrasonic waves in vitro. After the energy is focused at the target of the lesion in the body, the temperature above 65 ° C is instantaneously generated, so that coagulation necrosis and protein denaturation occur in the target lesions in the body. The tissue of the lesion is inactivated and gradually absorbed by the normal tissues of the body to achieve therapeutic purposes. "Early ultrasound focusing technology is mainly applied to oncology, especially for gynecological solid tumors such as uterine fibroids and uterine adenomyoma." Sun Fucheng, a professor at the School of Biomedical Engineering, Shanghai Jiaotong University, said that compared with other clinical treatments. Ultrasound focusing has the characteristics of no surgery, no bleeding, no pain, no damage to normal tissues, mild stress response, and positive promotion of immunity. In addition to treatment in the field of uterine fibroids, adenomyoma, breast tumors, pelvic and abdominal recurrence and metastatic solid mass, pancreatic cancer, liver cancer, etc., ultrasound focusing technology began to develop into more detailed specialized applications, such as the brain. The treatment of neurological ablation, chronic pain, Parkinson's and other diseases has also achieved certain clinical effects. Bring hope to more patients In view of the many advantages of ultrasound focusing technology, Shenzhen Prokheren Medical Technology Co., Ltd. (hereinafter referred to as Proheyin), which is dedicated to the development of large-scale ultrasound treatment equipment, was first established as a breakthrough in the development of ultrasound focused uterine fibroids treatment system. In only two years, the products entered the clinical trial stage and were carried out at Xijing Hospital of the Fourth Military Medical University, the First Affiliated Hospital of Jilin University and the Second Affiliated Hospital of Shantou University Medical College. The entire clinical trial was divided into two phases, which lasted for 5 years. A total of 112 cases were implemented and achieved good clinical results. In 2012, Prokhrin successfully introduced large-scale ultrasound focused non-invasive treatment system equipment for non-invasive treatment of gynecology to the market, and also obtained CE certification in the European market in the same year. "Our system uses the latest generation of circular self-focusing transducers to make the focused ultrasound channel distribution more uniform and reasonable while maintaining the therapeutic dose. It can selectively adjust the dose in the treatment channel to reduce the ultrasound to normal tissue. The injury.†Zhang Hui, president of Prohuiren, said that it is the product that incorporates these new technologies that makes patients not anesthetized, painless, and can guarantee the treatment effect, and also greatly improve the safety of the treatment process. However, the joy of product success did not stop Provien from stopping the pace of research and development. Subsequently, the company's research and development of ultrasonic pain treatment equipment successfully listed, by accelerating chemical reactions, strengthening metabolism, affecting enzyme function and biological active substance content, changing tissue structure, reducing sensory nerve excitability, increasing pain threshold and other comprehensive effects, Thereby achieving an analgesic effect. Zhang Ji told reporters that ultrasound focused therapy especially hopes that those who are old and weak, heart, lung, liver and kidney and other important organs are impaired, and those who are not suitable for surgery or middle and late patients see hope. Still need to be promoted and promoted It is undeniable that after years of development and clinical research, ultrasound focused therapy has benefited many patients, which again confirms that ultrasound focusing technology can achieve safe and effective in vitro ablation and inactivation of tumors in vivo. "The development of any medical technology requires a process of gradual development, maturity, perfection and standardization. Ultrasound focusing is no exception." Yu Jianhua, an attending physician of the Department of Oncology, Wangjing Hospital, China Academy of Chinese Medical Sciences, believes that the clinical application value of ultrasound focused therapy remains to be determined. Evidence-based medical evidence is strongly supported, but it is believed that it will certainly have a place in cancer treatment. However, the coverage of ultrasound focusing treatment equipment in China is still far from enough. Currently, it is only distributed in large hospitals in some big cities. "I hope that the county can reach the county-level hospitals in the future, so that the majority of patients can get easy and efficient non-invasive treatment without going far away, and let high-tech truly achieve the ultimate goal of the general public." Zhang Ji expects that the company can promote human health. The vigorous development of the business and the development of the application of non-invasive therapeutic technologies contribute more.

The magnetic bead method nucleic acid extraction kit is a high-tech product that combines biological science and nanomaterial science. It is a major breakthrough in my country's nucleic acid extraction and purification technology. .
Magnetic bead method for nucleic acid extraction has incomparable advantages over traditional DNA extraction methods, which are mainly reflected in: 1. It can realize automatic and large-scale operation. At present, there are 96-well nucleic acid automatic extraction instruments, and the extraction time of one sample can be realized. The processing of 96 samples complies with the high-throughput operation requirements of biology, enabling rapid and timely response to infectious disease outbreaks, which makes traditional methods unmatched; â‘¡ The operation is simple and time-consuming, and the entire extraction process has only four steps , most of them can be completed within 36-40 minutes; â‘¢ Safe and non-toxic, no toxic reagents such as benzene and chloroform in traditional methods are used, and the damage to experimental operators is minimized, which fully conforms to modern environmental protection concepts; â‘£ Magnetic beads and nucleic acids The specific binding of the extracted nucleic acid results in high purity and high concentration of the extracted nucleic acid.
According to the same principle as the silica membrane spin column, the superparamagnetic silica nano-magnetic beads are prepared after the surface of the superparamagnetic nanoparticles is modified and modified by nanotechnology. The magnetic beads can specifically recognize and efficiently bind to nucleic acid molecules on a microscopic interface. Using the superparamagnetic properties of silica-coated nanomagnetic microspheres, under the action of Chaotropic salts (guanidine hydrochloride, guanidine isothiocyanate, etc.) and an external magnetic field, samples from blood, animal tissues, food, pathogenic microorganisms, etc. The isolated DNA and RNA can be used in clinical disease diagnosis, blood transfusion safety, forensic identification, environmental microbial testing, food safety testing, molecular biology research and other fields.
Magnetic bead nucleic acid extraction can generally be divided into four steps: lysis-binding-washing-elution.
Genetic testing will surely become a new symbol of the development of the biological industry. The emergence of high-throughput, automated nucleic acid extraction methods will reduce the labor cost of genetic testing, make large-scale testing a reality, and make it possible for genetic testing to reach ordinary people.
