CCTV News:In the face of the epidemic situation, Shaanxi has opened 601 special green channels for epidemic prevention materials, fresh agricultural products and production and living materials at various highway toll stations to ensure the rapid and efficient passage of vehicles carrying materials inside and outside the province, and to help prevent and control the epidemic situation and protect people’s livelihood.

At the Afanggong toll station on the Xi ‘an-Baoji Expressway, the staff is inspecting and taking photos of the vehicles carrying the people’s livelihood security materials, and releasing them free of charge after passing the inspection. Due to the proximity to a large agricultural product logistics center in Xi ‘an, the Epanggong toll station has opened two green passages to facilitate the rapid passage of vehicles carrying people’s livelihood materials, with an average of more than 140 large trucks going up and down the green passages every day.

Kou Yu, stationmaster of Afanggong Toll Station of Shaanxi Traffic Control Group:On the premise of ensuring standardized transportation, the corresponding procedures are simplified, and the average passing time of each "Green Pass" vehicle is only 2-mdash; In 3 minutes, 75% of the goods pulled by the "Green Pass" vehicle are vegetables, 9% are fruits, and the rest are meat, eggs, milk and aquatic products.

Since the outbreak of this epidemic in Shaanxi province, the expressway management department has set up 601 green passages for epidemic prevention and fresh agricultural products at the toll stations in the province, set up indication signs, increased the number of people to keep traffic smooth, improved the traffic efficiency, and disinfected the toll station area and charge cards in time.

　　"Steaming on the top and cooking on the bottom" is the hottest time of the year. It seems that only ice and cold things can last, and even meals just want to eat ice. A delicious food that has been brushed frequently recently — — Chaoshan raw pickled, have you eaten it?

　　The method of raw pickling in Chaoshan is as follows: clean live shrimp, crab and shellfish, put them on a plate, add seasonings such as onion, ginger and cooking wine, and put them in the refrigerator.Freeze for hours or a day or two.A "raw salting" that is said to be addictive is ready.

　　The combination of seafood and raw salting has to be reminiscent of "parasites", and fish, crabs, shrimps and shellfish in seawater may carry parasites — — Anisodes. In this issue, we will take a look at the knowledge about anisakis..

　　What are the symptoms of infection with anisakis?

　　The general clinical manifestations of infection caused by anisakis nematodes are as followsGastrointestinal symptoms, or allergic reactions caused by repeated infections.After eating food containing live third-stage larvae of Anisodes, clinical symptoms usually appear in 1-12 hours.It is characterized by abdominal pain, nausea, vomiting, hematemesis, general fatigue, abnormal stool and other symptoms.In severe cases, larvae can penetrate the stomach or intestinal wall and migrate to peritoneum, pleural cavity, mesentery, liver, pancreas or ovary. Generally, the disease is self-healing, and the acute symptoms will disappear within a few days, but if left untreated, it can cause chronic ulcer-like symptoms, which last for weeks or even months.

　　Insects and their secretions can also cause strong allergic reactions, and the epitopes are urticaria, rubella, edema, even respiratory disorders, anaphylactic shock and so on.

　　Up to now, 12 kinds of simple anisakis allergens (Ani s1- Ani s12) have been reported, but only the first 9 allergens have been clearly identified and classified. Seven (Ani s1, Ani s4, Ani s5, Ani s6, Ani s7, Ani s8, Ani s9) are excretory and secretory allergens, and two (Ani s1, Ani s3) are allergens of the insect itself. Ani s1, Ani s2, Ani s3 and Ani s7 are the main allergens, and Ani s4, Ani s5, Ani s6, Ani s8, Ani s9 and Ani s10 are the secondary allergens.85% of people allergic to ANODONAS contain Ani s1-specific IgE. It is generally believed that,General anisakis allergy is caused by infection with live anisakis.However, it cannot be ruled out that contact with heat-resistant antigens or dead larvae may cause allergies.

　　Easily misdiagnosed? How to diagnose?

　　For the diagnosis of suspected cases,First of all, because of asking patients whether they have eaten raw and mature seafood.According to biochemical indexes and signs, it is different from other gastrointestinal diseases (acute appendicitis, intestinal obstruction, etc.). The diagnosis was assisted by endoscope and X-ray.

　　Fiberoptic endoscope is the most effective diagnostic method for the disease of Heterotopic Nematodes in esophagus and stomach. Using fiberoptic endoscope, we can directly find worms or find pathological changes such as erosion and edema on mucous membrane, and confirm them. At the same time, we can directly take out worms for treatment.

　　The X-ray signs of gastric anisakis disease are mainly longitudinal gastric wall wrinkling and swelling, and sometimes the larvae themselves are linear shadows. For anisakis enterobiasis, the X-ray sign of intestine is segmented after barium meal, and serrated or short rod-shaped shadows can be seen in the affected part, and the intestine above the affected part has strong expansion, in which the retained barium can be seen with granular shadows.

　　Ultrasound images can also be used to assist in the diagnosis of intestinal anisakiasis.When larvae cannot be found in the stomach and small intestine, immunological diagnostic techniques can be used to assist in the diagnosis of anisakis. Detection of IgG, IgA or IgE antibodies in the serum of suspected cases with larval excretory and secretory antigens, worm antigens or Anis1 allergens can assist in the diagnosis of recent and past infections, and has the advantages of high efficiency and strong specificity.

　　In the process of diagnosis and treatment,Anisodomy is easily misdiagnosed as acute appendicitis, intestinal tumor, localized enteritis, intestinal diverticulitis, etc.　It is difficult to get worms from the intestine, and the diagnosis is made by X-ray fluoroscopy and immunological blood clearing. Generally, albendazole conservative treatment combined with anti-inflammatory drugs is adopted.

　　There is no specific therapeutic drug for anisakis, and prevention is the key.

　　There is no specific treatment for anisakis, and the most effective treatment is to take out the worm as soon as possible.If the worm can’t be taken out, conservative treatment should be adopted, and observation should be strengthened while resisting infection and allergy. When the condition is serious, surgery should be performed to remove the worm in time to avoid local blockage.

　　We should adhere to the principle of giving priority to prevention for anisakis,Strengthen publicity and education for consumers and inform them of the dangers of eating immature processed seafood.Processing this kind of food should be cooked thoroughly to reduce raw seafood and fresh water products.Reduce food safety risks. It is advocated that related food enterprises and restaurants should freeze seafood before processing and selling it. Freezing can not only kill parasites in seafood, but also kill pathogenic Vibrio. The European Union stipulates that raw seafood must be frozen at -20℃ for at least 24 hours, and the US FDA requires that seafood eaten without being heated above 60℃ must be frozen at-35℃ for 15 hours or stored at -23℃ for at least 168 hours (7 days).

　　Focus on:Avoiding eating raw or half-baked marine fish is the primary preventive method, and the fish should be heated and cooked before eating. Anisodes can all die after being frozen at -20℃ for 24 hours.(Article source: "Jiangbin Hospital, Affiliated Hospital of Jiangsu University" WeChat WeChat official account)

Similar to fuel vehicles, electric vehicles also need energy-saving driving. Energy-saving driving is a complex system engineering related to people, vehicles, roads, etc. The technical level of the driver’s control of the vehicle is the key link that affects the energy consumption of the vehicle.

The last energy-saving driving tutorial explained how to realize energy-saving driving at different driving speeds, and the second content will explain: kinetic energy recovery operation tutorial.

Energy recovery is the main feature that distinguishes fuel vehicles from electric vehicles. The driving process of the motor is the process of discharging the power battery and the power consumption of the vehicle, while the braking process of the motor and the deceleration braking process of the vehicle are the process of charging the power battery by the motor. Therefore, it is the key to energy-saving operation to recover braking energy well.

There are two kinds of electric vehicle energy recovery operations: braking energy recovery and electric slow energy recovery.

Braking energy recovery

During the braking process, the motor charges the battery and mechanical braking occurs at the same time. Mechanical braking mainly relies on brake pad friction and tire friction to brake the vehicle, which will produce heat dissipation.

The shorter the braking time, the shorter the working time of the motor, the less energy recovery, and the greater the heat dissipation loss. Under the condition of ensuring safety, try to avoid sudden braking and sudden deceleration, and light braking can maximize the recharge of electricity.

When ordinary vehicles are running in urban areas, the braking energy dissipation accounts for 40%~50% of the total driving energy, and the braking energy dissipation is higher in short distance. Effectively controlling the braking energy recovery can generally extend the driving time of vehicles by 15%~20%.

Electric slow energy recovery

The electric retarder is similar to the liquid retarder of a fuel vehicle. It mainly uses the motor to reverse drag to convert the power or potential energy into electric energy, and then stores it in the battery (internal energy). There are two forms of electric retarder energy recovery, namely, the handle control and the cruise button control according to different vehicle types.

Control energy recovery by holding handle.

The operating lever for multi-stage energy recovery is shown in Figure 1, and the energy recovery level of the instrument is shown in Figure 2, which currently shows level 1. Only when the vehicle is in the Ready state and the speed is greater than 5km/h can the grade be adjusted. The default grade of taxi energy recovery depends on the current position of the fender.

Push the lever upward, and the energy recovery level will be improved, with the highest level being 5; pull the lever downward, and the energy recovery level will be reduced, with the lowest level being 0.

Cruise button control energy recovery

The SET+/- function button on the right side of the steering wheel is shown in Figure 1, and the energy recovery level of the instrument is shown in Figure 2. At present, energy recovery level 2 is displayed.

When the vehicle is in the Ready state and the cruise control function is not turned on (there are no gray and green icons for cruise control), the level can only be adjusted when the vehicle speed is above 5Km/h, and the default level of taxi energy recovery is level 2.

When braking is not needed in taxiing conditions, the cruise can be slowed down to level 0 by level modulation, and a longer taxiing mileage can be obtained.

Pull up the silver wheel (SET+) to increase the intensity level of energy recovery, and the highest level is 9, at which time the energy recovery is the largest.

Pulling down the silver wheel (SET-) can reduce the intensity level of energy recovery. The lowest level is 0, and there is no energy recovery at this time. After stepping on the accelerator or restarting the vehicle, the energy recovery level will jump to the default level 2.
