　　Bmw 5 series

　　In terms of design, the new BMW 5 Series shows a more tough and dynamic style. Compared with the current models, the front face design of the new car is more powerful. At the same time, it is equipped with a circular grille and boomerang daytime running lights, which shows the latest design language of BMW brand. It is worth noting that the new car does not adopt the giant grille design of BMW 7 Series, but maintains relative restraint and exquisite overall shape.

　　On the side of the car body, the new car shows smooth and smooth lines. The semi-hidden door handle is flush with the door, and the flat roof antenna makes the side look more concise and generous. The "Hough Corner" of the rear door is perfectly integrated with the C-pillar, which embodies BMW’s unique design concept. In addition, the details of the embossed number "5" on the black plaque highlight the uniqueness of the new car.

　　In terms of interior, the new BMW 5 Series adopts the latest family-style design style, and the continuous screen design of 12.3-inch instrument and 14.9-inch central control panel makes the whole interior space more scientific and modern. The new style of sports steering wheel and the introduction of iDrive 8.5 system have further improved the convenience and intelligent experience of driving. In addition, the new car has also been optimized in the logic of function entry, which makes it easier for drivers to access common functions.

　　In terms of intelligent driving, the new BMW 5 Series is equipped with the third-generation BMW intelligent driving system, which realizes the full-stack software self-research, and fully adjusts the road conditions in China and the driving habits of users. The L2+ intelligent driving assistance function of the new car has been updated more than 100 times according to the features of the China market, and has been localized and debugged more than 2,000 times, showing BMW’s leading strength in the field of intelligent driving.

In terms of transmission system, the new car is matched with an 8-speed automatic manual transmission to provide drivers with a smoother and more flexible driving experience. At the same time, the new car is also equipped with the 9th generation lateral dynamics management system, which can accurately analyze and predict the dynamic parameters of the vehicle, provide stable and accurate chassis adjustment, and give consideration to handling and comfort.

　　Bmw i5

　　The new BMW i5 is based on the new generation BMW 5 Series, but it is endowed with sharper and brighter lines, creating a unique sense of future technology. Compared with the fuel version, the new car has made many innovations in details, showing strong personalized characteristics.

　　On the front face, the kidney grille is still BMW’s iconic design, but on the i5, champagne gold elements are integrated around and around the grille, adding a touch of luxury to the new car. Angel eye headlights have been simplified, which is more in line with the modern aesthetic trend, highlighting the simple and exquisite design style.

　　On the side of the car body, the smooth body lines inherit the elegant temperament of BMW 5 Series, and at the same time, the new car cleverly designs the "5" glorious logo at the corner of Hoxhorn. This unique element presents a blue breathing effect when charging, which not only enhances the recognition of the vehicle, but also brings a unique customized experience to domestic users.

　　In the rear part, the taillight design of the new car is also ingenious, and the integration of L-shaped chrome decoration further enhances the luxury of the vehicle. This exquisite treatment of details fully demonstrates BMW’s perfect pursuit of luxury and technology.

　　In terms of interior, the new BMW i5 adopts the combined screen design of 12.3-inch LCD instrument and 14.9-inch touch screen, which is full of science and technology. The combination of embracing interactive light strip and concealed air outlet of air conditioner makes the interior space more simple and modern. It is worth mentioning that the flowing gold plaque in front of the co-pilot is inspired by the elements of China, which skillfully blends the oriental charm into the luxurious atmosphere.

　　For the experience of the rear passengers, the new car has also been fully upgraded. The addition of the rear suspended giant screen provides passengers with a more shocking entertainment experience. This luxury configuration from the BMW 7 Series has become an exclusive option on the domestic long-wheelbase version of the 5 Series. In addition, the new car is also equipped with Bowers & Wilkins surround sound system, four-zone automatic independent air conditioning and other high-end configurations, which further enhances the comfort and dignity of the rear passengers.

　　On the power system, the BMW i5 long wheelbase version is equipped with the upgraded fifth-generation eDrive electric drive system. The maximum power of the rear single motor can reach 250kW, the peak torque is 430 Nm, and the cruising range under CLTC conditions is as high as 567km. The standard-axis version of the M60 xDrive is equipped with a dual-motor four-wheel drive system, with a maximum power of 380kW and a maximum torque of 795 Nm. The acceleration time of 0-100km/h is only 3.8 seconds, which brings the driver the ultimate driving experience.

　　Editor’s comment:The new generation of BMW 5 Series, with the same model and starting price for oil cars and trams, is actually the most conservative and effective way for luxury brands to enter the era of electric vehicles. The choice is left to consumers, and the flexibility of price adjustment is left to terminal agents. Anyway, users are coming for the brand, and it is the greatest success not to be robbed by others. The simultaneous launch of the two models not only highlights BMW’s firm determination to parallel fuel and electric technology, but also its deep thinking and innovative practice for future travel modes. The elegance of the new 5 Series and the sense of science and technology of the i5 complement each other, and jointly build a new era of diversified and intelligent luxury travel. At this moment, we expect these two models to set off new waves in the market, bringing consumers more yuan and more cutting-edge driving experience.

　　Looking at the excellent media works that won the 28th China Prize for Journalism, it is impressive. From these award-winning works, we can see some commonalities of excellent works: always pursuing news, attracting users to participate and interact deeply with the help of advanced technology, which are vividly reflected in the works of media integration.

　　On March 5th, a meeting of the 13th National People’s Congress opened in Beijing. The picture shows the reporter interviewing NPC deputies. Photo courtesy /CFP

　　Journalism is life.

　　The China Prize for Journalism evaluates news works, and the basic judgment to measure the quality of a news work is the strength and weakness of news. Therefore, journalism is a very important measure in the evaluation of the China News Awards.

　　Guangxi Daily’s short video news "Liuzhou Rongshui Breakthrough | Guangxi Daily reporter" lost contact "for dozens of hours, and sent back the latest picture of the disaster area after crossing 40 landslides! Being able to stand out and win the first prize is because of its outstanding news. In such a sudden disaster as flash floods, these short videos have good timeliness and sense of scene, which not only promptly refute rumors and respond to social concerns, but also vividly present the touching image of grassroots party member cadres in emergency rescue and disaster relief, which has aroused strong resonance among the audience and achieved good communication effects.

　　The short video news "online celebrity Shops Queuing Survey" selected by Shanghai Radio and Television Station is good at depth. The reporters’ team was divided into different groups, and it lasted for three months to make unannounced visits in multiple identities, such as customers, scalpers and shopkeepers, revealing the deep-seated reasons behind the chaotic queue in online celebrity stores. From this, it can be seen that no matter how the media carrier and form change, it is the eternal value pursuit of journalists to expose the truth through in-depth investigation in view of the hot spots of social concern.

　　Plug in the wings of advanced technology

　　Under the background of media integration, new technologies are constantly emerging, which brings more possibilities for news editing and production. It is refreshing to integrate the media boutique "showing off skills". Technological innovation drives the innovation of expression techniques. The Road to Public Servants, released by CCTV Audio & Video, selects the most typical scenes, images and sounds in the political experience of the Supreme Leader General Secretary, and comprehensively uses various technical means such as a mirror to the end and three-dimensional projection. In just a few minutes, the protagonist has completed a 48-year time-space roaming, which shows the political character of the Supreme Leader General Secretary "always being a public servant" and creates a sense of sight. In particular, the expression of "one mirror to the end" fits perfectly with the ideological realm of the Supreme Leader General Secretary for 48 years.

　　Technological innovation brings innovation in discourse system. China Daily’s short video news "British Little Brother Counting the Key Words of" Two Sessions ",through the film and television stunt keying technology, reduced the British little brother Fontaine and put it on the desk. Through the novel form of interaction between Fontaine and the items on the desk, it reviewed the hot words of the two sessions in the past few decades, concisely combed the context of China’s economic and social development, and finally led to the exposition of the Supreme Leader General Secretary on" Chinese Dream "and" People ",which profoundly clarified that" People are " Through technical innovation, this work tells the story of China in a way that overseas readers are willing to accept and easy to understand.

　　Technological innovation forces content innovation. The Paper published the H5 product "Long Interactive Comic Book | Tianqu: A 36-year Water Diversion and Drainage Repair by Huang Dafa, an old village party secretary in Zunyi", with water as the main line, and various reporting forms such as pull-down long comic book, progressive animation, 360-degree panoramic photos, atlas, audio, video, interactive experience, etc., showing the historical long scroll in which Huang Dafa led the older generation to build canals to get rid of poverty and drove the new generation to get rich. Zhejiang news client’s short video news "In a word, let the mountains and rivers be as beautiful as poetry", the main creative team lasted for more than two months, and went to mountainous areas, islands, villages and cities for on-the-spot interviews, shooting and painting, which integrated various artistic elements such as painting, calligraphy and poetry, and was innovative in content and form. The title changes through the focus of landscape painting, resulting in naked-eye 3D effect. In the transition part, the blooming effect is used to realize the switch between ink painting and real scene, so as to achieve "seamless connection". The real scenes of eight regions are more artistic with poems with vertical subtitles.

　　Interactive experience leads to "viral" spread

　　In the era of mobile internet, news communication should not only meet the information needs, viewpoint needs and emotional needs of the audience, but also fully consider participation in interaction, so as to improve the arrival rate and effectiveness of communication and win the recognition of the audience, especially young people. The most impressive interactive "explosion" in 2017 is a typical case of embedding patriotic themes into phenomenal media products-the "military photo" H5 of the People’s Daily client. The successful screening of this work tells us that we should pay attention to people’s emotional experience in the new media communication pattern. The information dissemination mode from "you talk and I listen" to "communication and interaction" is not as good as the immersion mode of "personally participating and being in it". News is no longer the so-called "objective news", but the "temperature" news that is integrated into people’s emotional identity.

　　On April 20, 2017, China’s first cargo spacecraft "Tianzhou No.1" carried out its mission at Wenchang Space Launch Site. CCTV conducted a close-range VR live broadcast of the launch. The audience can not only face the shocking visual impact of the rocket launch through the screen, but also get an all-round immersive experience in rocket hoisting and transshipment. Through the multi-screen interactive mode of TV, PC and mobile social media, it seamlessly covers 72 hours before and after the live broadcast, achieving good communication effect. This live broadcast has made the news three-dimensional and sensible, changed the audience from passive acceptance to active acquisition, and enhanced the interactivity of news dissemination. It is a successful attempt to integrate the media form into live TV broadcast.

????Looking at these award-winning works, we have an intuitive feeling: in the era of media integration, media products in news production will be further developed by leaps and bounds. No matter what changes have taken place in the form of media products, the basic news cores such as synchronizing (restoring) news scenes, pursuing the truth and promoting social progress will not be lost. On this basis, with the development of media integration technology, there is still a lot of room for imagination in the way news content is presented. Intelligent media products combining big data and artificial intelligence, multi-technology integration, multi-role expression, professional production and user participation to complete the news dissemination process together will become a new trend of media production in the new era.

　　Recently, the reporter found that Fuyang Wildlife Park in Anhui illegally exhibited and artificially bred the Northeast Tiger, a national first-class protected animal, without obtaining an artificial breeding license. Affected by the dispute over the right to operate the zoo, a large number of wild animals died, including 20 Siberian tigers, 2 African lions, 3 giraffes and other precious wild animals. On May 13th, the zoo announced that it would temporarily close the park for three days. At present, the local forestry department has been involved in the investigation.

　　Behind the tragedy of the abnormal death of 20 Siberian tigers, there are a series of problems such as unlicensed breeding and chaotic management in private wildlife parks. In the face of doubts, the staff of the garden said that it is normal to be born and die, and the death of the Siberian tiger is not a human factor. "Because the garden needs profit, if the animals die, it will have a great impact on the garden, so they will be taken care of." Another garden staff member said that the tiger who died abnormally on the net "was not from our zoo, but from another boss. We don’t know what happened, and we are learning about the specific situation". The above statement is not only lacking in responsibility and unconvincing, but also suspected of forcing sophistry and even confusing right and wrong.

　　It is true that birth, aging, illness and death in nature are inevitable, but in an environment with high human intervention, the health and well-being of animals depend on careful management and scientific maintenance of human beings. If we only blame the death of a large number of wild animals on the "laws of nature" and ignore the possible dereliction of duty and illegal behavior in wildlife parks, I am afraid it is hard to convince people.

　　Did the Siberian tiger die of old age or illness? Is there any connection between the death of a large number of wild animals and illegal inbreeding? What adverse effects have been brought to the living environment of animals by issues such as equity disputes? This series of question marks needs to be straightened by relevant departments. No matter what the truth of the incident is, we can’t ignore a social consensus: human faults can’t make animals pay the bill, zoos can’t become "animal purgatory", and the basic ethics of animals can’t be ignored.

　　This incident is also a microcosm of the survival crisis of China’s private wildlife parks: blindly following the trend, lacking long-term planning and professional management, many private wildlife parks have buried hidden dangers since their birth, and few zoos can achieve profitability due to poor management and weak supervision. Under this circumstance, abnormal animal deaths are increasing. Under the background of market-oriented operation, how to break through the innovation and get out of the predicament in the operation mode of private wildlife parks is still a difficult problem.

　　No matter how innovative the garden is in management, it must respect the life of the animals in the park. It is illegal and criminal to kill wild animals illegally in the wild. Then, do animals need to be held responsible for dying and starving in the zoo? Who should bear the responsibility and what responsibility? Who should supervise and intervene when the enterprise is in poor management and in trouble? These problems still need to be further clarified by laws and regulations. The alarm bell is ringing, and wildlife parks in other places should also take the warning, be kind to wild animals, and stop simply treating them as "cash cows". (Chen Guangjiang)

Speaking of Tengshi, there should be many people who must know each other. This high-end new energy brand with BYD and Mercedes-Benz as endorsements released a notice on April 1st and started its brand-new course. Coincidentally, Lantu Auto also took a fancy to the "cake" of luxury MPV market, both of which are new forces and luxury MPV. Lantu’s dreamer and Tengshi D9 should be regarded as the most direct competitors. Then, who is more qualified to sit on the top spot of domestic luxury MPV? Let’s compare it!

Appearance contrast

Dreamer and Tengshi D9′ s exterior design are all high-end executive MPV shapes, so they have square and wide body lines and a more atmospheric and stable image like traditional MPV.

Compared with the Lan Tu FREE, which locates the SUV, the straight waterfall air intake grille of the Dreamer’s car head has become larger in area, and a lot of chrome decoration has been used.

Viewed from the side, the front of the Dreamer is longer than the traditional MPV, and the 20-inch multi-spoke wheel hub conforms to its image of taking care of both business and home. In terms of vehicle size, it also completely surpasses the Buick GL8, which is almost equal to the V-class long wheelbase model.

At first glance, Tengshi D9′ s tall and plump front and the grille design with inverted trapezoid structure look a bit like Erffa. On the side of the car body, a prominent through waistline is added to the standard shape of high-end commercial MPV. In addition, as a medium and large MPV, Tengshi D9 also surpasses Buick GL8 and Erffa in size, but it is slightly different from the dreamer.

If we must compare the face value, Tengshi D9 is more in line with the author’s aesthetic standards for a high-end MPV.

Interior contrast

Dreamer’s interior adopts the multi-screen design of Lantu FREE. Although the screen lifting function is cancelled, it still looks very scientific and technological, and the interior materials and workmanship still maintain a high level.

Although the appearance of Tengshi D9 is basically divorced from BYD’s existing design framework, the interior is still full of "Diwei". The suspended central control panel and the dual-spoke steering wheel are familiar smells. Similar central control design is common in BYD’s 100,000-300,000 models, and now Tengshi, which is positioned at a higher end, is directly copied. Fortunately, Tengshi D9 uses better materials in leather and decorative boards, so the overall texture should be much higher than BYD’s.

Comparison of space comfort

In terms of comfort, the dreamer has an oversized and flexible space layout, a wheelbase of 3 meters 2, 2+2+3 seats and a central passage layout. The second row of seats also provides electric leg rest, lumbar support, seat massage, heating and ventilation functions, which can bring more comfortable feelings when riding. In addition, the second row also provides a small table board, the switch button of the electric sliding door, the air conditioning control panel, the cup holder, the USB charging port and the small drawer, which can be described as meticulous care.

The second row of Tengshi D9 is also full of materials. First of all, the function control area is placed on the armrest of the seat, in the form of a small LCD screen; In addition, the second row provides two large LCD screens for passengers to enjoy audio-visual entertainment. Not only that, the second row also provides a car refrigerator that can hold 8 bottles of water. As for the unexposed configurations such as small tables, Zhao Changjiang also said that "there is a solution".

Dynamic contrast

Dreamer will launch a pure electric version and a plug-in hybrid version. The plug-in hybrid vehicle is equipped with a dual-drive motor with front 130 kW/rear 160 kW, and the total power of the power system reaches 290 kW. At the same time, the vehicle is equipped with a 1.5T engine, and the total peak torque of the system reaches 610 Nm. The cruising range of pure electric mode (CLTC standard) is 82km, and the comprehensive cruising range (WLTC standard) is 720km.

The pure electric version is equipped with ternary lithium battery, with a maximum power of 320 kW and a peak torque of 620 Nm. Depending on the configuration, 82kWh and 108.7kWh batteries are provided, and the cruising range (CLTC standard) is 475km and 605km respectively.

The power of Tengshi D9 has not been announced yet, but it will provide two power forms of DM super hybrid EV, and Tengshi also promises that the comprehensive cruising range of vehicles equipped with DM super hybrid technology will exceed 1000 kilometers. With BYD’s new energy technology as an endorsement, the author is confident about Tengshi D9′ s battery life.

Write it at the end

Comparatively speaking, the internal and external designs of Dreamer and Tengshi D9 have reached the level of high-end MPV. In terms of performance, Tengshi D9 has BYD’s technical endorsement, so it will be more recognized in the market; However, in terms of selling price, Lantu Dreamer is 369,900-689,900 yuan, and the starting price of Tengshi D9 may be around 450,000 yuan. Therefore, on the whole, the competitiveness of the two models is quite equal. Which model do you think has a brighter future? Welcome to leave a message below to discuss with Xiaobian!

Original Shanghai No.10 Hospital Pharmaceutical Service Shanghai No.10 Hospital Pharmaceutical Service

China’s population aging process is accelerating. In 2020, China’s population aged 60 and over has reached 18.70%. The elderly are at higher risk of malnutrition, especially those with multiple diseases or serious diseases. Once the elderly patients are diagnosed with malnutrition, comprehensive and detailed nutritional assessment should be made within 48 hours, and personalized nutritional intervention strategies should be formulated for patients to ensure adequate dietary intake and improve nutritional status. Oral nutritional supplements (ONS), enteral nutrition (EN) and parenteral nutrition (PN) are commonly used ways to supplement nutrition in clinic.

Our previous popular science article "Rumoured Enteral Nutrition" has introduced the relevant knowledge of enteral nutrition. Today, I will take you to understand what parenteral nutrition is.

one

What is parenteral nutrition?

Parenteral nutrition (PN) refers to a way of intravenous infusion of nutrients such as amino acids, glucose, lipids, electrolytes, vitamins and trace elements, so that patients can maintain their nutritional status even if they can’t eat, and improve their clinical outcomes.

For elderly patients who need nutritional support treatment, when EN intake is lower than 60% of the body’s energy and protein’s target requirement, it is suggested to give supplementary parenteral nutrition. When the gastrointestinal function of elderly patients is seriously impaired or EN cannot be used, total parenteral nutrition is recommended.

2

Is single bottle infusion better or "all in one" (total nutrient mixture)

Infusion is good?

"All-in-one" infusion means that various nutrients such as carbohydrates, fat emulsion, amino acids, vitamins, electrolytes and trace elements are fully mixed in an infusion bag according to a certain reasonable ratio (sugar-fat ratio, hot-nitrogen ratio, electrolyte concentration, etc.) and then infused.

Compared with single-bottle infusion, "all-in-one" infusion is more in line with the physiological metabolic process of the body, which can make the nutrients input into the body better metabolized and utilized: (1) It can reduce the occurrence of metabolic complications, and avoid increasing the metabolic load due to more glucose or fatty acids entering the body in a unit time when a single-bottle infusion of hypertonic glucose or fat emulsion is used, and even complicated with related metabolic complications, such as hyperglycemia or hyperlipidemia; (2) The nutrients can be diluted with each other, so as to reduce the overall osmotic pressure and reduce the stimulation to veins; (3) It can avoid the need to change the infusion bottle many times during single bottle infusion, simplify the infusion process, save nursing time, reduce the chance of pollution and reduce the risk of related infection.

three

Classification and characteristics of total nutrient mixture

At present, the total nutrient mixture is mainly divided into two forms: industrial multi-cavity bag (including three-cavity bag and double-cavity bag) and hospital preparation (commonly known as "three-liter bag"). So what’s the difference between the two?

Industrialized multi-cavity bag is to divide a special preparation bag into several relatively independent cavities, and fill them with nutritional ingredients such as fat milk, amino acids and glucose respectively. When in use, just squeeze to open the inner cavity partition belt and mix several liquids fully and evenly. Multi-cavity bag has many specifications, and has the characteristics of reasonable prescription, stable quality and ready-to-use, which can reduce prescription and configuration errors, reduce microbial contamination and bloodstream infection, and meet the needs of parenteral nutrition for most patients.

However, for patients who need to strictly limit the amount of liquid and electrolyte intake, have serious metabolic disorders and have special nutritional needs, it is still necessary to prepare individualized parenteral total nutrition mixture in the hospital.

four

How to prepare parenteral total nutrient solution in hospital?

The parenteral total nutrition mixed solution prepared in the hospital was prepared by PIVAS according to the personalized prescription prescribed by doctors and audited by pharmacists, and was mixed and mixed by pharmaceutical professionals in strict accordance with the operation sequence of parenteral nutrition mixed preparation under the clean environment of horizontal laminar flow table.

The prepared parenteral nutrient solution should be used now to avoid direct sunlight; If it needs to be stored, it should be placed in a refrigerator at 4℃ to avoid light and refrigerated, and it should be rewarming before infusion; Even in cold storage, the time from the end of infusion must be limited to 48 hours to ensure safety and effectiveness.

five

Can other drugs be added to parenteral total nutrient solution?

In order to reduce the volume load of patients, parenteral nutrition mixture may be used as the infusion carrier of drugs in clinic. Strictly speaking, neither industrial three-cavity bags nor hospital preparations can be used as infusion carriers for other drugs.

The mixed total nutrient solution is a relatively stable system. If other drugs must be added, it is necessary to carefully evaluate the stability of the system and the effectiveness of each component, and closely monitor the adverse reactions and pharmacological activities of the drugs during the medication.
