Micro-check

On the way Fan Dong returned to Q City, although he was in a heavy heart, he was not confused. He at least had a bottom line in his heart. He was grateful to Zhou Ning and Zhou Xun for their sincerity in treating him, especially Zhou Xun. His professionalism made Fan Dong feel that he had He found a backer, and he even thought that even if he was really infected with HIV, it would not be a big deal. Anyway, people must die. Compared with those people who were hit by a car when they went out and died immediately after getting cancer, they were at least lucky. .

When he returned to Q City, he sent Zhou Ning two boxes of Cordyceps, two boxes of sea cucumber, two bags of dried abalone, and two boxes of dried truffle.

Zhou Ning picked him up and went to pick up the courier at the gate of the yard.

The courier brother often delivers to his home, and Zhou Ning also sends a lot of couriers, and the two have become familiar with each other for a long time. Zhou Ning asked doubtfully, "I haven't bought anything recently, so why do I have couriers?"

The courier boy said: "It's still very heavy, a big box."

Zhou Ning glanced at it, and saw that the sender's name was Fan Dong. He was even more surprised, "It was sent by Brother Fan. He didn't just go back this morning. What is it?"

After signing for the receipt, Zhou Xun came over to carry the express box for him, "What's inside, it must weigh more than ten catties."

"I don't know, let's take it into the house and have a look."

Zhou Ning closed the gate of the courtyard. It was already seven o'clock. Looking up at the sky, it was already dusk, and the sound of cars speeding past could be heard in the distance. It was people who got off work and were rushing home, while his lover was walking on the road. In front of him, walking into the warm light of the house, this made him feel the tenderness of the years, the eternal warmth at this moment.

Zhou Ning went into the kitchen to see the stewed bone soup. Zhou Xun put the delivery box on the long table in the kitchen, took a knife to open the box, Tao Tao jumped from the ground to the chair, jumped onto the table, and squatted on the box. Staring from the side, eyes focused, like staring at his cat food.

As soon as Zhou Xun lifted the lid of the box, he smelled the seafood inside, raised his head and said to Zhou Ning, "It's dried seafood."

He took out the contents one by one, and when he found that they were all valuables, he said in surprise: "Brother Fan is really expensive, he sent us a lot of high-end ingredients."

Taotao was fascinated by the taste of sea cucumber and abalone, and kept patting the box of sea cucumber and the bag of abalone with her paws. Zhou Ning came over and rubbed Taotao's head, looked at the things on the table, and said, "He Don't be so polite."

Zhou Xun said: "It's not good to accept this, just keep it. After I read it, I will give him some skin care products that protect the liver and kidney as a gift in return."

Zhou Ning also had the same opinion.

Zhou Ning called Fan Dong with a headset while cooking, while Zhou Xun went upstairs to tidy up the room and bathroom that Fan Dong had used.

He wiped the bedroom and bathroom with alcohol, and put away Fan Dong's used toiletries and put them in double-layer bags, preparing to take them to the laboratory for sterilization the next day.

Fan Dong said on the other end of the phone: "I sorted out my mood for a day today, and I will return to work normally tomorrow. You can tell Zhou Xun that I have taken my medicine on time, and there is no major reaction."

Zhou Ning said while serving the dishes: "Well, okay, then you should take care of yourself. Next time you come to City C for inspection, give me a call first, and I will pick you up at the station."

"it is good."

Zhou Xun entered the kitchen and saw that Zhou Ning was carrying the dish, so he hurried over to take it in his hand and put it on the table.

Tao Tao is usually very selfish and doesn't particularly like to cling to the two shit shovelers, but at this time he has been turning around Zhou Ning's legs. Zhou Ning took a step back and almost stepped on his tail. He had to squat down and hold Tao Tao Tao picked him up and put him on the chair, "I know you miss abalone and sea cucumber, but those are not for you. Be good, don't pester me again."

Taotao squatted obediently on the chair, but as soon as Zhou Ning turned around, he immediately jumped off the ground and continued to spin around Zhou Ning's legs. Zhou Ning: "..."

Zhou Ning was afraid of stepping on him, so she had to pick him up and prepare extra meals for him, and let Zhou Xun serve the soup and rice.

One tomato stewed beef brisket, one corn bone soup, one stir-fried vegetables, and one purple potato crisp.

Taotao squatted on the side eating cat food, and the two shit shovelers could have a good dinner.

"Since Brother Fan sent so many things, I will make black truffle egg rolls for you tomorrow morning, and you can stew soft-shelled turtles with caterpillar fungus in the evening." Zhou Ning said.

Zhou Xun was very satisfied with stewed beef brisket with tomatoes. The tomatoes had been stewed into juice. The sweet and sour taste of the tomatoes had entered into the beef brisket, and the rich meaty flavor of the beef was mixed in the juice. It was enough to eat three bowls of rice.

Zhou Xun nodded contentedly, "Cordyceps stewed soft-shelled turtle, will it be too nourishing, what should I do if my nose bleeds."

"Eat once a month, no problem. And I only put one." Zhou Ning said, put a big stick bone on the plate in front of Zhou Xun for him to eat, thought for a while and said: "Brother Fan You gave us two boxes, you can take the other box to your parents. Anyway, we can eat one box for a year, and the other box is too long, it’s not good.”

Zhou Ning likes to cook, but she doesn't eat much. Zhou Xun eats [-]% full every time, so although Zhou Ning cooks a lot of dishes, the portion of each dish is small.

In front of Zhou Xun was the big stick bone that Zhou Ning gave him, and it was the only stick bone in the soup. While picking off the meat and putting it into Zhou Ning's bowl, he lowered his head and said, "Then again Buy two boxes and give each of your parents a box, that's just right."

Zhou Ning's parents divorced when he was four or five years old. The two started their own families, and the new family had new children. Zhou Ning was raised by his grandmother. After his grandmother passed away a few years ago, Zhou Ning Ning never went back to his hometown, and hardly contacted his parents.Zhou Ning had told Zhou Xun all these things, so Zhou Xun knew.

Zhou Ning ate the meat that Zhou Xun gave him, and said calmly, "No, they never thought of me, should I still think about them?"

Zhou Xun wanted to say that it was the parents who gave birth to him after all, but seeing Zhou Ning's unhesitating expression, he shut up.

Zhou Ning said, "Then I'll send that Cordyceps to your parents tomorrow."

In the past, Zhou Xun sent things to his parents from the hospital by himself, but later Zhou Ning said that he sent more things, not to mention the price in his store, even if the family sent SF Express, the express delivery was cheaper for him every time. A lot, just to save a few dollars, Zhou Xun asked Zhou Ning to send it on his behalf.

Zhou Xun smiled at Zhou Ning and said, "Thank you."

作者有话要说：我懒得自己打字解释，就找了一篇论文里的一部分给大家看：HIV病毒耐冷不耐热,一般来说,HIV在4摄氏度条件下可存活7~10天，-20摄氏度下生存数周,在超低温状态下(-70摄氏度和-196摄氏度)可保持其传染性长达数月至数年,病毒存活表现出随温度升高而下降的规律。本研究发现,在冷藏(4摄氏度)和自然温度(25摄氏度)条件下,液体环境中的HIV可存活24h以上,仍具有感染人T淋巴细胞的活性,37摄氏度下随着时间的延长,HIV滴度的下降程度明显高于4摄氏度和25摄氏度,存活时间少于24h,这提示,尽管HIV病毒十分脆弱,离开人体后很难长时间存活,使得HIV在自然环境中传播的可能性非常小,但在适宜条件下,如湿润、适宜温度时,一段时间内HIV仍存在感染性。因此,实验室工作人员应重视冷藏和室温下HIV病毒污染物品的消毒,避免实验室HIV感染事故的发生。

In this study, HIV virus infectivity was lost after 37 hours at 24 degrees Celsius, which was less than the survival period of 7-14 days in related studies by Fan Weiping and others. This may be related to the difference in virus strains and target cells used, but both The conclusion that the virus titer decreases with the increase of temperature is clear, and it is basically consistent with the results of foreign related research.

病毒的结构不同,对各种理化因子的敏感性会有差异,有包膜的亲脂性病毒对化学因子,如某些表面活性剂的敏感性高于无包膜的病毒,但是,它们对热则都有较高的敏感性。HIV病毒是带有包膜的RNA逆转录病毒,正如本研究结果显示,随着温度的升高,病毒悬液中HIV滴度的下降速率明显加快,37摄氏度条件下放置24h,病毒感染性丧失,56摄氏度下10min或70摄氏度下2minHIV病毒可被完全灭活,与国内外相关研究结果基本一致,说明HIV病毒对温度非常敏感,加热是灭活HIV的最简便有效的手段。

However, the above are all laboratory conditions. In a general environment, it depends on the content of the virus and the characteristics of the virus itself to determine its infectivity.
