Deep and fierce investigation

Text/photo reporter Song Wangqun

Camellia oil, also known as camellia seed oil, is commonly called "Yuezi oil" by citizens. With the implementation of the "two-child" policy, camellia oil is becoming more and more popular. However, the reporter’s investigation found that the quality of camellia oil currently on sale in the market is mixed, and even some brands still have "adulteration" behavior. A citizen of Shenzhen recently bought six pure camellia oils and sent them to Shenzhen Institute of Metrology and Quality Inspection for inspection. The inspection results showed that none of the six pure camellia oils met the national standards. The person in charge of Shenzhen Consumers Association said that related products are suspected of false propaganda, and consumers can ask for ten times compensation.

Customer complaint: online shopping for camellia oil actually detected "adulteration"

Mr. Zheng is in charge of purchasing in a company in Shenzhen. "The Spring Festival is approaching. According to the company’s arrangement, he bought a batch of camellia oil through the Tmall flagship store of six brands of camellia oil and gave it to the company’s customers." Mr. Zheng said, "The six brands of camellia oil are all 5L specifications, and the price ranges from more than 200 yuan to more than 600 yuan per bottle. The sellers all claim that their products are pure camellia oil, and the quality grade is the first grade. You can buy them without adding any other edible oil ingredients."

"But some familiar customers told me that the camellia oil received was not pure enough and had no natural fragrance of camellia oil." Mr. Zheng said, "The camellia oil I purchased is purchased through Tmall flagship store, unless there is something wrong with the product itself." In order to find out, Mr. Zheng sent one of the camellia oils to a testing institution for testing.

"The test results surprised us. Other vegetable oils were detected, which did not meet the national standards. It was not pure camellia oil. Isn’t this adulteration?" Mr. Zheng said.

Recently, the reporter checked the Taobao Tmall purchase records and invoices of Mr. Zheng’s purchase of camellia oil, as well as the unopened camellia oil products. In the column of quality grade, all six products are marked as "first class", "international first class" or "squeezing first class", the product standard number is "GB11765", and the ingredients are "camellia seed oil".

According to the national standard GB11765 issued by the General Administration of Quality Supervision, Inspection and Quarantine, all products marked with "Camellia oleifera seed oil" should meet the standard, which requires that "Camellia oleifera seed oil should not be mixed with other edible oils and non-edible oils, and should not be added with any flavors and fragrances".

On the afternoon of January 8, the reporter accompanied Mr. Zheng to send six kinds of camellia oil to Longhua experimental base of Shenzhen Institute of Metrology and Quality Inspection for inspection. On January 17th, the inspection report was released. The inspection report showed that none of the "Rapeseed Oil Purity Test" of six brands of camellia oil met the requirements of the first-class standard for crushing, and other vegetable oils existed in the measured values (see the above figure). In addition, two of the camellia oils are not up to standard in terms of refractive index, iodine value, oleic acid and linoleic acid.

Insiders: The cost per catty is about 80 yuan.

On January 22 nd and 23 rd, the reporter called six camellia oil manufacturers to verify the situation. Among them, the service calls of three manufacturers were not answered. The manufacturer of Jinx responded that all the products submitted by the company were up to standard, and said that the same batch of products submitted by Mr. Zheng had been sampled for inspection. A person in charge of X township factory who claimed to be Vice President Zhou said that the report submitted by consumers for inspection has no legal effect. The manufacturer of Green X responded to the reporter that the company sent tea oil for inspection many times, all of which met the national standards.

Zhang Gong, who has been engaged in the camellia oil industry for more than ten years, said that at present, the price of purchasing a kilo of camellia oil by the people is generally around 80 yuan, and the weight of a 5L bottle of camellia oil is 9-10 kilos. The most expensive camellia oil purchased by Mr. Zheng is more than 600 yuan, and the average price is only more than 60 yuan a kilo, which is far lower than the private purchase price.

Zhang Gong said that if the mixed ingredients are controlled within 10%, it is basically difficult to detect. If even the indexes such as refractive index, iodine value, oleic acid and linoleic acid are not up to standard, it can only show that more other edible oil ingredients are mixed.

Shenzhen Consumers Association: Related manufacturers are suspected of false propaganda.

On January 23rd, the reporter reported the situation to Shenzhen Municipal Market Supervision Administration and Shenzhen Consumers Association. According to the Shenzhen Municipal Market Supervision Administration, since it is an online shopping product, consumers should report it to the industrial and commercial administration department where the product trademark is located.

The Shenzhen Consumers Association said, "The product is advertised as 100% pure tea oil, but the result of the consumer’s inspection is that it is mixed with other edible oil, which is suspected of false propaganda. According to the rule of’ one fake and ten penalties’, consumers can ask for 10 times compensation, and the market supervision department will investigate it." The staff of Shenzhen Consumers Association said that the laws and regulations on online shopping supervision are still not perfect, and it is difficult for consumers to protect their rights. At present, Mr. Zheng can only complain to the industrial and commercial departments where the trademarks of the purchased products are located.

　　Xinhua News Agency, Changchun, January 29th Since the winter vacation, many places in Changchun and Shenyang have opened ice and snow custodians. Schools have built ice rinks and snow fields on campus, hired professional coaches, and provided all kinds of ice and snow sports courses for primary and secondary school students, so that students can enjoy ice and snow on campus during the winter vacation and welcome the Winter Olympics.

　　In the cold winter, in the 2,400-square-meter ice rink of Pingquan Primary School in Nanguan District, Changchun City, the students learned from the skating coach in full swing.

　　Song Haoxuan, a student in Class Two, Grade Five, Changchun No.104 Middle School, is learning skating for the first time. After three days, he has mastered the basic movements and can stand and walk on the ice. "Before the holiday, the class teacher said that there was ice and snow custody during the holiday, so I signed up. In the past, I could only do my homework at home during the holidays. It is so interesting to learn skating this time. " Song Yuxuan said.

　　At the scene, the reporter saw that a shoe changing room was built around the skating rink, in which all the skating equipment was prepared for students, and each school was accompanied by leading teachers to ensure the safety of students.

　　Sun Jingru, director of the Department of Physical Education, Sports, Arts and Health, Nanguan District Education Bureau, Changchun City, said that in order to create conditions for students to participate in ice and snow sports, Nanguan District Education Bureau poured an ice rink in Pingquan Primary School. Students in grades 4-8 of primary and secondary schools in the whole district took advantage of the winter vacation to participate in ice and snow custody for a total of 30 days, with about 600 participants every day. The total number of participants in the winter vacation is expected to be 18,000. The Education Bureau also hired seven professional coaches to guide students’ ice skills, so that students can master the basic skating movements and experience the fun of skating in a short period of time.

　　In addition, other counties and cities in Changchun also provide various forms of ice and snow amusement activities for primary and secondary schools. Yushu city City, Jilin Province has poured 26 outdoor ice rinks in primary and secondary schools in towns and villages, and equipped students with PE teachers and skating equipment. Up to now, more than 10,000 people have participated in ice and snow custody.

　　In the ninth primary school in Hunnan District, Shenyang City, Liaoning Province, ice and snow activities are another lively scene. The school’s snow machine makes snowflakes fly, and it is fun to have snowball fights, make snowmen and snowball. Two large indoor ski machines allow students to ski at zero distance, and more than 700 students who participate in the trusteeship can enjoy the fun of flying in the snow.

　　Hou Mingfei, principal of the Ninth Primary School in Hunnan District, Shenyang, said that compared with summer classes, the school’s winter vacation trusteeship has increased the single and double snowboarding projects, and students can take skiing classes on campus.

　　On the 120-square-meter indoor simulated ice rink of Heping Street No.1 Primary School in Heping District, Shenyang, the children were dressed in ice hockey equipment, and the teacher explained the technical points and basic sliding movements for the students. The slightly childish movements of the students added vitality and vitality to the winter campus.

　　The school organized a winter vacation hosting service with the theme of "Harmony, Colorful Winter Holidays", and 80 students from different grades signed up to participate. The trusteeship classes were named "Bingdundun" class and "Snow Rongrong" class, and activities such as learning to sing winter Olympic songs and ice hockey experience were also carried out to cultivate students’ interest and skills in ice and snow sports.

　　This school is a characteristic school of ice and snow sports on the national youth campus. Lin Yuheng, the director of teaching, said that ice hockey training in schools usually involves members of the school team, and not all students can master skills such as ice hockey and speed skating. There is plenty of hosting time in winter vacation, and for more than 80 students who participate, they can do no less than two hours of sports every day.

　　In recent years, Shenyang has incorporated ice and snow projects into the teaching content of primary and secondary schools, and carried out ice and snow sports through physical education courses and comprehensive practical activities courses, and achieved remarkable results. Twenty-seven schools in the city were rated as "National Youth Campus Ice and Snow Sports Characteristic Schools" by the Ministry of Education, and 55 schools were named as municipal ice and snow characteristic schools. At present, more than 30% primary and middle school students in the city have mastered the basic skills of ice and snow. (Reporter: Li Shuangxi, dorri, Wang Ying, Wu Jiangmin)

Renal artery denervation (RDN) is a hot topic in the field of hypertension in recent years. Although it has not been widely used in clinic, with the release of various clinical data, more and more industries focus on RDN.

RDN targets the sympathetic nervous system, which does play a role in raising blood pressure. Therefore, RDN selectively reverses a mechanism of hypertension. But hypertension is a multifactorial disease. Is it really enough to target a single pathogenic mechanism to produce effective and sustained blood pressure reduction in a large number of hypertensive patients? Yixin specially interviewed the vice president of Hebei Provincial People’s Hospital.Professor Guo Yifang, shared his views on the future prospects of RDN.

　 One more proof of RDN’s long-term effect 　

Recently, the three-year research results of RADIANCE-HTN SOLO test were published, which confirmed that the safety and effectiveness of ultrasonic RDN lasted for 36 months.

Patients with ambulatory blood pressure ≥135/85 mmHg and < 170/105 mmHg after 4 weeks of stopping antihypertensive drugs were randomly divided into ultrasound RDN group or sham operation group. The results of 36-month follow-up showed that the systolic blood pressure and diastolic blood pressure in RDN group decreased by 17.7 mmHg and 11.3 mmHg respectively compared with baseline. In terms of safety, there were no adverse events related to equipment or operation during the follow-up period.

In response to this research result, Professor Guo Yifang pointed out that in recent years, the effectiveness and safety of RDN has been an important topic in the field of hypertension treatment, which has attracted extensive attention from scholars at home and abroad.Radiation-HTN solo research provides valuable new evidence for the instrument treatment of hypertension. However, Professor Guo is cautiously optimistic about the results of this study, considering the differences in the conclusions of several RDN studies published in recent years and the limitations of this study itself..

　 The evidence-based road of RDN 　

The basic principle of RDN is to block the afferent and efferent activities of sympathetic nerve around renal artery by radio frequency energy, ultrasonic energy or injecting heat into perivascular space, and reduce the influence of sympathetic nervous system on renal vascular resistance, renin release and sodium reabsorption. RDN blocks the signal conduction between the brain and sympathetic nerve to a certain extent, thus reducing the sympathetic nerve excitability of patients with hypertension. Theoretically, it can achieve long-term antihypertensive effect through a minimally invasive operation.

As early as 2009 and 2010, RDN completed two early clinical trials in Europe and Australia, namely Symplicity HTN-1 and HTN-2. The results of 3-year follow-up showed that the average systolic blood pressure and diastolic blood pressure of refractory hypertensive patients receiving RDN decreased by about 30 mmHg and 14 mmHg respectively, and there were no obvious adverse reactions and complications. More importantly, after three years of follow-up, these patients found no obvious signs of blood pressure rebound.

Because this is the first minimally invasive surgical technique that has been proved in history and can definitely lower patients’ blood pressure, RDN shines brilliantly after the above exploratory experiment, but the well-known sham-operated control experiment-Symplicity HTN-3 did not get positive results, which weakened people’s enthusiasm for RDN: although the research proved its safety, it did not significantly lower blood pressure compared with the control group.

On the basis of summarizing the research experience and lessons of SYMPLICITY HTN-3, the researchers subsequently carried out a new generation of randomized controlled trials, such as SPYRAL HTN-OFF MED, SPYRAL HTN-ON MED, SPYRAL HTN-OFF, etc. These studies used different techniques and methods to ablate the renal artery sympathetic nerve. The results showed that the ambulatory blood pressure and clinic blood pressure in RDN group decreased clinically regardless of whether antihypertensive drugs were used or not.

Clinical research course of RDN

In different studies, compared with sham operation group, systolic blood pressure in RDN group decreased.

The REQUIRE study aims to evaluate the effectiveness and safety of ultrasound renal artery ablation system in controlling blood pressure in patients with refractory hypertension. 143 patients with refractory hypertension (office blood pressure ≥150/90 mmHg and 24-hour SBP≥140 mmHg) were randomly assigned to RDN or sham operation group. Three months after operation, there was no significant difference in the 24-hour ambulatory systolic blood pressure between the RDN group (-6.6 mmHg) and the sham operation group (-6.5 mmHg) (P=0.971). The difference of SBP between family self-measured blood pressure and clinic blood pressure was -1.8 mmHg(P=0.488) and -2.0 mmHg(P=0.511) respectively, and there was no difference. There was no significant difference in drug load between the two groups. No major adverse events related to the operation were found.

At the EuroPCR annual meeting in 2022, a number of research data of RDN were published: Global Symplicity Registry, SPYRAL HTN-ON MED, Radiation HTN Solo & Trio, which further confirmed the potential of RDN as an adjuvant therapy for hypertension, supplemented the existing first-line therapy, and thus changed the lifestyle and drug treatment.

　 Professor Guo Yifang: RDN can be expected in the future 　

The occurrence of hypertension is a complex process, involving many mechanisms, and it is not expected to solve all patients’ problems through one drug or technology. RDN only blocks renal sympathetic innervation, and may have no therapeutic effect on other mechanisms that cause and maintain hypertension. Moreover, the antihypertensive effect of RDN is moderate, which is only equivalent to taking an antihypertensive drug.

Professor Guo Yifang talked about the future prospect of RDN. He pointed out that RDN is still in the stage of research and exploration, and it can not be used as a mature treatment technology in clinical practice. From the pathophysiological mechanism, the sympathetic nervous system plays an important role in the occurrence and maintenance of hypertension, so in theory, RDN will definitely have an ideal effect on some hypertensive patients. butThe pathophysiological mechanism of hypertension in different patients is inconsistent, the renal artery structure in different patients is obviously inconsistent, the principle of different types of RDN technology and equipment is inconsistent, and the experience and technical level of different operators are inconsistent. These four "inconsistencies" will inevitably affect the effectiveness and safety of RDN treatment and its application value and clinical status in antihypertensive treatment..

On the whole,For patients whose blood pressure can’t be satisfactorily controlled after lifestyle intervention and adequate treatment with various antihypertensive drugs, patients with obvious sympathetic hyperactivity, or patients who can’t tolerate antihypertensive drugs, it is reasonable to carry out RDN treatment in mature medical centers.. It is believed that RDN will play a more important role in the field of hypertension treatment in the future with the progress of related technologies and the continuous improvement of treatment equipment.

Guangdong, a place easy to get angry.

For Cantonese people,

If you have a nosebleed

Nine times out of ten, it is getting angry.

Especially now when the weather is dry and things are dry.

Cantonese will remind you to drink herbal tea at once.

If there is a long-term nosebleed,

And it’s when there’s blood in the tears

We are about to start to be vigilant.

This could beGuangdong cancer!

nasal pharyngeal cancerIt is a malignant tumor located in the nasopharynx, also known asGuangdong cancerAccording to the statistics of the World Health Organization, there are80%Nasopharyngeal carcinoma (NPC) occurred in China, especially in Guangdong. The cancer detection data of our province released by Guangdong Provincial Center for Disease Control and Prevention in 2019 shows that at present, nasopharyngeal carcinoma ranks eighth among residents in Guangdong Province, with an incidence rate of 14.84/100,000.Far higher than the national average.

Speaking of nasopharyngeal carcinoma,

I have to mention

Epstein-Barr virus closely related to nasopharyngeal carcinoma

"Reasonable Inspection" Series No.twenty-eightperiod

Let’s have a chat.

Nasopharyngeal carcinoma and EB virus

epstein barr virus

"Good friend" of nasopharyngeal carcinoma, EB virus

Epstein-Barr virus is considered to be the strongest pathogenic factor of nasopharyngeal carcinoma at present. Epstein-Barr virus (EB virus) is one of the most widely infected herpes viruses. It is highly contagious and can be spread through droplets, kissing, sharing tableware and other behaviors, as well as through blood and semen during sexual contact, blood transfusion and organ transplantation. Epstein-Barr virus infection is very common in normal people. It is reported that more than 90% people have been infected with Epstein-Barr virus, and once infected, the antibody of Epstein-Barr virus will be carried for life.

Note: Autumn is the high incidence period of EB virus infection, so try to avoid going to crowded places to avoid cross-infection. Wear a mask when going out and take protective measures.

Then the problem is coming.

EB virus positive = nasopharyngeal carcinoma?

Epstein-Barr virus detection usually includes early antigen IgA antibody detection of Epstein-Barr virus, Rta-IgG detection of Epstein-Barr virus, and qualitative detection of Epstein-Barr virus DNA.

When EB virus antibody is positive, nasopharyngeal carcinoma can not be diagnosed. More than 90% of adults have been infected with EB virus, and only about 3%-10% of people with EB virus antibody positive will turn into nasopharyngeal carcinoma patients, indicating that the occurrence of tumors is not caused by EB virus alone, but by genetic and environmental factors.

Don’t panic when you find EB virus positive in physical examination. Consult your doctor as soon as possible. The doctor can judge whether you are a high-risk patient by asking about your place of origin, family history, living habits and whether you have symptoms. According to the doctor’s advice, you may have an imaging examination for further confirmation. The 5-year survival rate of early nasopharyngeal carcinoma can reach 97%, so early detection is very important!

Epstein-Barr virus is indeed closely related to nasopharyngeal carcinoma. Accurately speaking, Epstein-Barr virus is a related substance of nasopharyngeal carcinoma, not a marker of nasopharyngeal carcinoma.

epstein barr virus

If you have the following symptoms, you should be alert to nasopharyngeal carcinoma.

VCA-lgA titer ≥ 1: 80;

All the EB virus indexes were positive;

Check the EB virus index, any one continues to rise.

When EB virus is positive, nasal congestion occurs; Reflux nasal discharge with blood; Vision loss and ghosting; Cervical lymph node enlargement; Ear buzzing and hearing loss; Headache; Facial numbness, etc., need more attention.

What are the high risk factors for nasopharyngeal carcinoma?

At present, the pathogenic factors of nasopharyngeal carcinoma are not clear, except EB virus infection, which may be related to genetic factors, environmental factors, dietary factors and other factors.

01

Gender:

Nasopharyngeal carcinoma is more common in male population, which is 2~3 times higher than that in female.

02

Race:

Nasopharyngeal carcinoma is common in China, Southeast Asia and parts of North Africa. Inuit people also have a higher risk of nasopharyngeal carcinoma than other ethnic groups.

03

Region:

Guangdong, Guangxi, Fujian, Hunan, Jiangxi and other places in South China and East China belong to areas with high incidence of nasopharyngeal carcinoma, among whichPearl River DeltaThe area is particularly obvious.

04

Age:

May occur in any age group, butMostly in 30~50 years old..

05

Diet:

Love foodPreserved foodSome people will also increase the incidence of nasopharyngeal carcinoma. Pickled food contains a lot ofAmmonium nitrite compoundLong-term intake can increase the incidence of nasopharyngeal carcinoma by 2~7 times.

06

Alcohol and tobacco:

manysmokeanddrink wine/alcoholIt will also increase the risk.

07

History of sinusitis and family history:

If someone in the family suffers from nasopharyngeal carcinoma, especiallydirect relativeThe risk of illness will also increase.

People who meet one or more of the above conditions are at high risk of nasopharyngeal carcinoma, so it is necessary to screen nasopharyngeal carcinoma.

epstein barr virus

Prevention: early detection+self-discipline is the key!

How to prevent nasopharyngeal carcinoma?

● Quit smoking and drinking, eat less pickled food;

● Epstein-Barr virus is mainly transmitted through saliva, and infants should not be fed mouth to mouth;

● Maintain good hygiene habits: wash your hands before meals, do not spit everywhere, and advocate the use of public chopsticks;

● If you get up every day and find that you often have a runny nose and are accompanied by bloodshot or bleeding symptoms, you must be vigilant;

(Source: Healthy Guangdong)

● In areas with high incidence of nasopharyngeal carcinoma, people with family history of nasopharyngeal carcinoma, and middle-aged and elderly people, EB virus detection should be taken as a necessary item for physical examination.
