Media correspondents asked whether, in recent times, many people felt that they had a large number of friends and friends on their own. Please ask whether this year’s influenza pandemic is more severe than in previous years? How should the public have a scientific response?

Researcher on HIV/AIDS at the China Center for Disease Control and Control, presented, according to data from the national influenza monitoring data, the prevalence of this influenza pandemic is type A H1N1 and H3N2, dominated by type A H1N1a. Overall, the level of influenza activity increased in early February, with a marked upward trend towards the end of February, reaching peaks by mid-March, followed by a resurgence of abductions. Abductions in the northern provinces took place in mid-March and in the southern provinces in early April. There is a downward trend in influenza in all provinces of the country.

Chen presented two features of this shifting season: one that was approximately two months late in the normal winter season and that the influenza level of activity showed a trend towards a gradual north-to-south transition to the popular season; and the second that the mobility of this shift was slightly higher than the year of the natural influenza pandemic that preceded the new coronary outbreak, during which the converging epidemic was significantly increased, mainly in schools.

Chen stated that, in response to seasonal influenza, it was recommended that the general public should receive timely influenza vaccinations, pay attention to personal protection, particularly in the areas of handicrafts, ventilation, discipline and good mindset. In addition, the existing tetra heterosexual anti-retrovirus drugs are effective for the current strain.

He told reporters: “I live alone. I’m old and can’t take good care of them. I have to give them up and donate them with the feeling of marrying my daughter.”

“My bonsai is different from others. Many people tie the tree head with iron wire, which will be distorted. My bonsai has not been tied with wire. The bonsai comes from nature and is higher than nature.” Chen chukang believes that art is priceless. He rejected all those who bought bonsai from him at a high price and donated it to the staff service center of the Municipal Federation of trade unions free of charge. “I chose this place because I regard the staff service center as my home. I hope to build a staff bonsai garden here in the future, so that bonsai lovers can visit, study and exchange. I can also come to see them often. At the same time, I hope the center can hold bonsai lectures or training.”

Guo Xiaoping, director of the staff service center of the Municipal Federation of trade unions, thanked Chen very much. “These bonsai have added style to the central courtyard”.

The team said: “We have cooperated with the French Dreem company. Dreem has developed the flexible self adhered hydrogel as the wearable flexible brain computer interface for its new generation of electroencephalogram and electroencephalogram bioelectricity sensors. Compared with commercial electrodes such as wet electrode Ag/ AgCl and silane dry electrode, the EEG signals recorded by super soft water gel almost have no artifact. Now, it shows good stability and accuracy. “

The researchers said that the brain computer interface has established a direct communication bridge between the brain and external artificial devices, which can be used to monitor the function of the brain and is of great significance in the diagnosis and treatment of neurological diseases. We hope that this hydrogel can be used as a long-term implantable brain computer interface for monitoring EEG signals in patients with neurological diseases such as Alzheimer’s disease, Parkinson’s disease and traumatic brain injury.

In addition, after fast Fourier transform of EEG in resting state detected by the material, obvious features can be found at about 10 Hz α Wave is expected to be used to track human sleep, so as to provide a new drug free way to effectively improve sleep conditions and alleviate the symptoms of neurasthenia of modern people

It is understood that the preparation of hydrogel as the conductive interface and the integration of flexible brain computer interface can achieve seamless connection between rigid microcircuit and soft brain tissue, providing a design idea for stable and accurate monitoring of EEG long-term implantation of BCI materials. Related papers are published on the topic of “Bioadhesive and conductive hydrogel-integrated brain-machine interfaces for conformal and immune-evasive contact immune-evasive” with “brain adhesion and conductive hydrogel integrated brain computer interface” which is seamless with brain tissue and immune escape ability.

According to the paper, this study mainly adopts the “double bond dopamine limited domain polymerization 3, 4 ethylene two oxygen thiophene (EDOT)” to prepare hydrophilic ultra-small conductive polymer nanoparticles (dPEDOT NPs) and introduce it into the “carrageenan polydopamine polyacrylamide” network, and by introducing catechol functional groups into the hydrogel. Preparation of conductive and transparent hydrogel to avoid rejection.

The researchers said that the research focused on the design of material system and made a preliminary attempt as a brain computer interface. Later, the team will continue to do more systematic and in-depth research on this topic, and will try to solve the biodegradation problem of hydrogel brain computer interface, and avoid the tissue damage caused by the two removal after implantation.
