Pulse wave technology - prevent cardiovascular disease, more accurate in local measurement

Pulse wave  technology - prevent cardiovascular disease, more accurate in local measurement

Many people believe that only elderly people need to pay attention to vascular health. The true fact is that aging and damage of blood vessels have accelerated since the age of 30.

With the influence of age, lifestyle and other factors, there are gradually hardening artheromatous plaques on the walls of arteries. They are like stones on highways, which can lead to poor blood circulation and even blockage of blood vessels, eventually causing cardiovascular and cerebrovascular diseases and thus endangering life and health.

According to the "Cardiovascular Disease Report 2017", cardiovascular disease has become the leading cause of death among residents, with 45.01% in rural areas and 42.61% in cities.

What is the pulse wave velocity?

When the blood vessel blockage is less than 70%, the human body does not have any warning sign, and often miss the best prevention time, so the prevention of cardiovascular disease is very important, and it is necessary to carry out vascular health check regularly.

With advancement in technology, pulse wave velocity (PWV) is increasingly being applied to arterial vascular examinations. Pulse wave velocity (PWV) refers to the rate of pressure wave conduction along the wall of the aorta generated by the heart beat . It is easy to operate, fast, and repeatable. A PWV test usually takes only 1-2 minutes.

Clinical significance of pulse wave

PWV is one of the main means to assess the degree of atherosclerosis because it can reflect the elasticity and strain capacity of blood vessels. It can predict the potential pathological factors in the early stage of vascular injury and play a better role in preventing cardiovascular disease. The larger the PWV measurement, the worse the vascular elasticity and the greater the risk of cardiovascular disease.

Atherosclerosis causes vascular occlusion and affect blood circulation

Clinical Application of PWV

Rapid and objective analysis of vascular system function

• Quantify arterial stiffness and enhancement

• Helps in understanding cardiovascular health

• Promote supervision of medication, treatment, and lifestyle

• Assist in the control of disease development

Traditional PWV technology has large measurement error

The PWV obtained by the traditional pulse wave measurement technique required the average value of the whole blood vessel.It is impossible to accurately locate which blood vessel segment has lesions and plaques, thus the measurement error is large. In the early stage of atherosclerosis, plaques are often very small, and the PWV measurement for local blood vessels is more valuable.

 

PWV technology is positioned accurately.

Local measurement is more reliable.

The PWV technology is a new type of non-invasive and reproducible pulse wave velocity detection technology. It has a higher imaging frame rate than the traditional B-mode ultrasound and greatly improves the accuracy of local PWV measurement.

Through the analysis of 29 test subjects, the results show that the Vinno PWV technology overcomes the influence of the previous technology on the blood pressure fluctuation of the subject, it is able to trace the waveform of the carotid wall in multiple cycles, and observe the wall of the blood vessel in real time. Identify the situation and improve the credibility of the results.

Focusing on prevention, early diagnosis and precise intervention is a new direction for the development of health care. Vinno arterial local PWV measurement technology can effectively evaluate vascular stiffness, and provide objective detection indicators for the screening and evaluation of risk factors for arteriosclerosis. It is a great significance for the early detection, treatment and prognosis of arterial diseases

3.5 kg! Lightest and most durable , VINNO 6 on military channel !

At below 30 degrees with snow and ice closures, seeking medical treatment has become a major problem to all the officers at HeiLongJiang.

So,the hospital committee quickly organized a patrol team to travel along the boundary river. At certain path, vehicles are unable to reach, they can only walk on snow,and the footsteps are clear audible in the snow.

 

The director of the special department, Xiang Jiabing, is a member of the patrol team and is responsible for the ultrasound scan of the soldiers. Along the way, she was always concerned about one thing: to visit the house of the border defense health section, to provide a health screening to the family member with 8 months pregnancy.

 

The equipment to be used for these health-screening must not only excellent in image quality, but also light in weight as it is not easy to walk on snow.

 

In order to go without burden, the director specially brought a portable color ultrasound system VINNO 6. Unlike the other 20-pound "portable" equipment , it is compact and only 3.5 kilograms, which can be taken away with one hand.

"This device truly reflects the meaning of portable ultrasound, and its two-dimensional and blood flow images are excellent and easy to operate."

With the support of such high-end technology, right hand of the director is holding the probe, while the left hand touches the screen, and the scanning process is completed smoothly in a few minutes. The fetus is healthy and the other family members stop worrying.

In recent years, miniaturization, specialization, and intelligent portable ultrasound have brought more possibilities to clinicians. This is inseparable from the efforts of a group of ultrasound technology researchers.

Chen Yinren, the director of the operation of Vinno, said: "VINNO 6 is the lightest portable color ultrasound in the industry. It is equipped with a self-developed RF platform to restore information to the greatest extent. With 23MHz high-frequency probe and unique "Neddle guide" function. It can be said that it is already at the world's leading level

Climbing over snow-capped mountains, passing glaciers, going to the post, entering the igloo, the patrol team stepped over more than 20 rounds of patrols, and provide medical services to the northern part of the country, and VINNO 6 was accompanied by their footsteps… 

This is our common wish: let cutting-edge ultrasound technology help doctors go further and make the officers at the borders stay healthy and happy.

How far is breast cancer from us?

How far is breast cancer from us?

 

When it comes to breast cancer, I will first think of Xiulan-Deng Boer. In 1972, she had breast cancer and underwent a mastectomy. At that time, most women felt that they were suffering from this disease and did not dare to disclose it. She became the first celebrity to show her story to the public and advocate for breast cancer prevention. In 1993, Audrey Hepburn, known as the "human angel", died of breast cancer. Then, Yao Beina, who is well known to us, failed to overcome the unfortunate death of breast cancer. How terrible is breast cancer? How far is it from us? This article can answer your doubts.

Why do people get breast cancer? Human have breasts, and the troubles arise along with them. This trouble is known as breast cancer. The ancient Egyptian medical literature first documented breast cancer, calling it "the tumor on the breast," and the author wrote, "There is nothing can be done."

 

 

Because the location of breast cancer is very eye-catching,the evil shadow of breast cancer appeared in many of the paintings. Rafael's "Fornarina" is considered to be the first artwork to show signs of breast cancer, with obvious lumps and orange peel-like changes under the left chest.

According to NBCF (nation breast cancer foundation): no one knows the exact cause of breast cancer. Doctors also rarely know why some women have breast cancer, while others do not have breast cancer, and most women with breast cancer fail to accurately identify the cause of the disease. What we can know is that breast cancer is caused by the destruction of cellular DNA.

Q ： Breast cancer survival rate?

According to the American Cancer Society's data analysis, the 5-year survival rate of stage 0 and stage 1 breast cancer is 100%, and the five-year survival rate of stage 2 is as high as 93%. Professor Li Menghuan, director of the Department of Breast Surgery, the First Affiliated Hospital of Zhengzhou University, also believes that the sooner breast cancer is detected, the better the breast-conserving effect of patients. Most patients have a survival period of more than 5 years, and some patients can survive for up to 30 years. If the diagnosis is in the middle and late stage, the opportunity to preserve the breast will be lost, and the five years survival rate will be greatly reduced.

Q : Can breast fibroma becomes cancerous?

A large proportion of women will have breast fibroma during physical examination, causing a great panic. However, breast fibroma has a very low chance of developing cancer. Ordinary fibroma, about 3cm, grows slowly, relatively isolated. The larger size of the fibroma the greater likelihood of becoming cancerous. If the pathological result says "complex fibroma", the risk of developing this type of breast cancer will be higher than normal. If nodules or masses are found, they need to be treated in a regular hospital as soon as possible.

 

Q : How to prevent breast cancer?

Experts recommend a monthly breast self-examination, a clinical examination and ultrasound scan every 4 to 6 months. Above the age of 40, breast screening is performed once every 1-2 years. Patients with high-risk suspicious lesions can prevent breast tissue resection. In addition, [reducing the intake of high-fat, high-calorie, high-salt content foods], [regular long-term exercise]can reduce the risk. Athletes have the lowest incidence of breast cancer. [Avoid drinking] The risk of breast cancer in drinking is higher than in those who drink less. [Less coffee] Coffee, cocoa, and chocolate. These foods contain a lot of caffeine, which can promote breast hyperplasia. [eat more cabbage and soy products and fish], late pregnancy after the age of 30, it is likely to increase the risk of breast cancer.

 

Q : What are the methods of breast cancer screening?

Breast cancer is not an incurable disease. Early screening is particularly important for long survival and high quality of life. In addition to the simplest self-examination, the early screening of breast cancer requires three major weapons to work together. They are ultrasound, magnetic resonance and genetic testing. The three are indispensable. . In current medical practice, almost any type of scanning examination has alternatives, such as ultrasound or magnetic resonance imaging. Regarding the roadmap for breast cancer screening, we also follow the "no radiation" approach: breast ultrasound - magnetic resonance - genetic testing.

Breast ultrasound can detect occult microscopic lesions of 3 to 5mm, which can effectively identify early breast cancer. In addition, it can be identified whether the mass is cystic or solid, and its diagnostic accuracy for breast cysts is as high as 95%, which can avoid unnecessary biopsy. In addition, color Doppler can identify the benign and malignant breast lumps through blood flow signals.

 

The professional ultra-wide diameter breast transducer provides better sensitivity to the detection of lesions and provides a more effective and comprehensive method of breast examination.

Breast magnetic resonance

Magnetic resonance imaging is excellent in breast cancer screening, especially for invasive breast cancer, which is difficult to detect clinically. And the most important thing is that magnetic resonance can be done in multi-plane imaging and image reconstruction. For existing lesions, the size, shape, extent of invasion and lesion metastasis can be well displayed.

Breast cancer genetic screening 

In May 2013, when Angelina Jolie published "My Medical Choice" in The New York Times, the world was in turmoil. Because she found herself a carrier of the BRCA1 mutation gene and had a 87% chance of developing breast cancer, she immediately chose to undergo a preventive mastectomy. She is known as the hero of the era of personalized medicine. In the three months after Julie's article was published, Meliad Genes announced that its revenue reached $202 million, a 52% increase over the previous fiscal quarter, and the company attributed this to the Angelina effect. Based on this data, we can also see the unique advantages of genetic testing for breast cancer prevention.

When we use color Doppler ultrasound or magnetic resonance to detect benign lesions, we can also do a genetic test to further understand the specific situation and avoid unnecessary biopsy. For example, BRCA1, BRCA2 and other genes can be screened for breast cancer. If they have any of these genes and can cause mutations, there is a 40-70% chance of getting breast cancer, and the probability of developing ovarian cancer will also increase.

Early screening of breast cancer can be done by color doppler ultrasound, magnetic resonance, genetic testing, any of the results, in fact, there may be errors. Only when the three are combined to detect breast cancer from different angles can a comprehensive
