Women must take a special posture, called cystolithotomy position, and doctors use a special gadget to expose the cervix. Use a small brush to rotate around the cervix for 5 times to obtain cervical epithelial cells from the brush.
There are many methods of laboratory examination. There are PCR gene amplification technology and HC2 technology. Some check DNA, some check RNA. There are qualitative and quantitative inspections. This non-invasive brushing cervical sampling method is no matter what kind of inspection sampling method. Qualitative examination can determine what type of human papillomavirus infection it is.
? The spread of human papillomavirus is mainly through direct contact with infected parts or indirect contact with articles contaminated by the virus. The transmission of human papillomavirus infection in newborns passing through the birth canal is mainly through direct contact with infected parts or indirect contact with articles contaminated by the virus, which mainly infringes on human skin and mucosa and causes proliferative lesions in different degrees. Different types of human papillomavirus invade different sites and cause different diseases, among which condyloma acuminatum and cervical cancer are the most harmful.
Condyloma acuminatum is transmitted through sexual contact, which accounts for the second place of sexually transmitted diseases in China, mainly through male penis, anus and surrounding skin, female vulva and vagina. Pink soft lumps are produced in the lesions, which protrude from the epidermis and have a rough surface, such as cauliflower-like protrusions. Clinicians usually make a diagnosis based on medical history and typical clinical manifestations.
? Clinicians aseptically collect pathological tissues of patients' skin and mucosa, and send pathological specimens to the laboratory. Clinicians aseptically collect pathological tissues of patients' skin and mucosa, send pathological specimens to the laboratory to check whether there are cancer cells and diseased cells, or directly draw blood for examination. At present, it is impossible to isolate and culture in vitro, and the laboratory mostly uses PCR technology to detect human papillomavirus for diagnosis.
Cervical cancer does great harm to women's health and is one of the main causes of female death in the world. Among the incidence of female malignant tumors, cervical cancer ranks fourth. With the continuous development of medical technology, the incidence of cervical cancer in developed countries has obviously decreased in recent years, but the incidence and mortality of cervical cancer in developing countries are still high.
? China mainly adopts the three-step screening model for cervical cancer. The first step is thin-layer liquid-based cytology? +Three-step screening mode for cervical cancer is mainly adopted in China for detection of human papillomavirus. The first step is thin-layer liquid-based cytology? +human papillomavirus test, if there is any problem, the patient should be examined in the second step, that is, colposcopy. If there is still a problem, we should continue to carry out the third step of examination, that is, histopathological examination, and conduct cervical biopsy on the patient, and finally give a more accurate diagnosis.
Human papillomavirus (HPV) is an epitheliophilic and myxovirus-philic virus, which is widely distributed in humans and animals. Non-carcinogenic human papillomavirus skin infection can be asymptomatic, but also can cause anal and external genital warts, which are vegetable-like, flat, papules or keratinized; Anal pruritus, burning, pain and other symptoms are common.
? Women's knowledge of cervical cancer can effectively improve the screening rate of female human papillomavirus, improve the screening rate of female human papillomavirus and reduce the occurrence of cervical cancer. Before screening women for intervention, 48% people knew about human papillomavirus, while only 23% people knew about the relationship between human papillomavirus and cervical cancer. Cervical cancer is a common cancer in women, which is closely related to human papillomavirus.
You can do a white acetate test in the genital area, and the white part indicates that it is white acetate positive and accompanied by genital human papillomavirus infection; For patients who are difficult to judge whether they are infected with human papillomavirus, exfoliated epithelial cells can be scraped from the body surface for human papillomavirus gene detection and genotyping. This can confirm whether someone is infected with HPV.
