Advances In Research On Pathogenicity Of Genital Mycoplasma

Medical Beauty
Mycoplasma genus (Mycoplasrnagenitali-um, Mg) belongs to the genus Mycoplasma, a prokaryote between bacteria and viruses, and the 12th mycoplasma found by humans. In 2009, the European guidelines for the treatment of non-gonococcal urethritis (NGU) have clearly identified that Mg is one of the causes of NGU. In 2010, the US CDC also emphasized the pathogenic role of Mg in the diagnosis and treatment of cervicitis. In addition, the diseases associated with Mg are also Including pelvic inflammatory disease (PID), obstetric complications, prostatitis, epididymitis and foreskin balanitis. In recent years, studies have also found that Mg infection may be related to the development of tumors and HIV. Since Tully et al. first isolated and cultured 2 strains of Mg from the urethral secretions of m...

Advances In Antibiotic Resistance Of P.acnes

Medical Beauty
Propionibacterium acnes (P. acnes) is a rod-shaped, spore-free, flagellate-free, Gram-positive anaerobic bacterium that resides mainly in the skin, gastrointestinal tract, and genitourinary tract. It is an opportunity. The pathogen is closely related to acne. P. acnes secretes a variety of substances (proteases, lipases, porphyrins, etc.) directly involved in the development of acne; it can also release IL-1, TNF-α, IL-8, IL-12 and the body through the Toll-like receptor pathway. Proinflammatory cytokines such as IFN-γ are involved in the inflammation and immune response of acne. P. acnes can effectively control and treat acne by inhibiting or killing P. acnes. However, due to the long-term and repeated use of antibiotics in acne treatment, drug resistance P. acnes is widespread worldwide

Clinical Epidemiology And Prevention Of Herpes Zoster

Medical Beauty
Herpes zoster is a viral skin disease caused by the reactivation and replication of latent varicella-zoster virus (VZV), a cluster of blister with nerves distributed in a unilateral distribution. Pain is characteristic. Herpes zoster is self-limiting, but serious cases and complications reduce the quality of life of patients and increase the economic burden of patients' families and society. It is important to understand the clinical epidemiological characteristics and prevention of herpes zoster. In recent years, a number of pooled analyses have summarized the clinical epidemiological characteristics of herpes zoster. The results are representative, but vary depending on the study data source or post-herpetic neuralgia (PHN) definition. 1. Clinical epidemiology of herpes zoster 1.1 Path...

Progress In Research On Nodular Scleroderma

Medical Beauty
Nodular scleroderma (NS), also known as keloid-like scleroderma (KS), is a rare subtype of scleroderma, which was first described by Addison in 1854. The etiology and pathogenesis are unclear, and the diagnosis mainly depends on clinical and histopathological examination. The clinical research progress of this disease is summarized as follows. 1. Etiology and pathogenesis 1.1 Cause The cause of this disease is unclear. It has been reported that hepatitis C virus (HCV) infection is closely related to certain skin diseases such as pruritus, cutaneous vasculitis and lichen planus, long-term HCV infection and others. Interactions of environmental factors lead to problems with autoimmune regulation, and can also cause nodular lesions in patients with scleroderma. In addition, acid-resistant ...

Research Progress On The Relationship Between Trauma And Melanoma

Medical Beauty
Melanoma, also known as malignant melanoma, is a highly malignant tumor that occurs mostly in the skin, accounting for the third place (6.8% to 20.0%) of skin malignant tumors, accounting for 3.0% of all tumors. The incidence rate is The average speed of 4.0% to 6.0% is increasing year by year. Among patients who die from cancer, melanoma accounts for about 1.0%. Because of the high degree of malignancy, unclear etiology, complicated pathogenesis, and lack of specific early diagnosis, studies on the etiology and pathogenesis of melanoma have attracted more and more attention from clinicians. Melanoma is derived from melanocytes, which are widely found in the basal layer of the squamous epithelium such as the skin, mouth, part of the nasal cavity and vaginal mucosa, and also in the ectoderm...

Application Of Picosecond Laser In Dermatology

Medical Beauty
The modern skin cosmetic laser works according to the theory of selective photothermal action, so that laser light of a certain intensity and specific wavelength is specifically absorbed by the target color base (such as melanin, hemoglobin, water, etc.) in the tissue, thereby destroying the target; The control of the laser emission pulse concentrates the energy on the target tissue, reduces damage to the surroundings, and reduces adverse reactions. In recent years, picosecond lasers with extremely short pulse widths have been used in dermatology clinics, providing new means of treatment. 1.Working principle The effects of laser action on skin tissue are the basis of its treatment, including biostimulation, photochemical reactions, and photothermal effects. It has been found that when th...

Advances In Research On Microcirculation Changes Of Psoriasis Skin

Medical Beauty
Psoriasis is a common chronic, relapsing, inflammatory skin disease with obvious seasonality. It recurs or aggravates in winter and relieves in summer, which seriously affects the aesthetics and quality of life of patients. The exact pathogenesis is still unclear and is currently considered to be related to genetic factors, environmental factors, and immune factors. In recent years, the role of skin microcirculation changes in the pathogenesis of psoriasis has received increasing attention. The microcirculation of the skin is divided into microvessels and microlymphatic vessels, which are mainly distributed in the dermis layer and the subcutaneous fat layer. The microvessels are composed of terminal small arteries, arteriovenous capillaries, and posterior venules. Psoriasis patients with l...

Skin And Intestinal Microecology And Probiotics

Medical Beauty
The germination of microecology at the end of the 19th century, which emerged in the 1970s, is the science of studying the interdependence and mutual constraints of human, animal and plant-dependent normal microflora. Many microbes live in the channels of the human body that communicate with the outside world. They have no harmful effects on the human body and are called normal flora. The normal flora community is in a dynamic equilibrium, which exists between different species, between the normal flora and the host, between the normal flora, the host and the environment. If there is a major change in the internal and external environment, this balance will be destroyed, and micro-ecological disorders will occur. If it cannot be adjusted in time, it will lead to various diseases in the hos...

Advances In Research On Correlation Between Epidermal Permeability Barrier And Pigment Barrier

Medical Beauty
In recent years, a large number of studies at home and abroad have shown that there is a close relationship between the epidermal permeability barrier and the pigment barrier. The epidermal pigment barrier can affect the epidermal permeability barrier function through the acidic environment of the epidermis and the pigment precursor material; while the epidermal permeability barrier regulates the epidermal pigment barrier function through lipid components and substances secreted by keratinocytes. Under normal circumstances, these two barrier functions should be in a steady state, and in some pigmented diseases (such as chloasma, vitiligo, etc.), the function of the two is abnormally changed. This paper will study the correlation between the two. The progress is reviewed. 1.Epidermal perme...
