ABSTRACT
Lactic acid is the main substance produced by Lactobacillus and plays an important role in maintaining a healthy vaginal microecology. Recent studies indicates that both L- and D-chiral isomers of lactic acid can be protonated and destroy the cell membranes of pathogens, thereby inhibiting bacterial vagi-nosis- and aerobic vaginitis-related pathogens. Lactic acid also can inhibit the pathogens of sexually transmit-ted diseases such as Chlamydia trachomatis and human immunodeficiency virus. Moreover, lactic acid acts as an immunomodulator to inhibit the inflammatory responses caused by pathogenic microorganisms and as an epigenetic regulator regulating gene expression in vaginal epithelial cells. In this paper, we reviewed the pro-gress in lactic acid-mediated maintenance of a healthy vaginal microbiology in recent years for providing ref-erence for further research.
ABSTRACT
Objective To analyze the value of vaginal microecological detection in evaluating therapeutic effect of simple vulvovaginal candidiasis(VVC), and explore microecological factors which can affect the cure rate of simple VVC.Methods 75 patients with simple VVC in Tianjin Medical University General Hospital from January 2016 to June 2017 were enrolled.Vaginal secretion was collected and applied for vaginal microecological detection.The patients were treated with clotrimazole based monotherapy later. The relationship between vaginal microecological characters and therapeutic effects was analyzed.Results PH values,leukocyte counts,flora density,flora diversity,small bacilli and cocci counts had no influence on therapeutic effects(P>0.05).The cure rate of patients with lactobacillary gradesⅠ-Ⅱa was higher than that with lactobacillary gradesⅡb-Ⅲ(83.33% vs 53.33%,P=0.033), while lower with lactobacilli≤22.8/hpf than that with lactobacilli >22.8/hpf(59.26% vs 87.50%,P=0.007), which indicate that lactobacilli counts was the main factor that affects therapeutic effects.Conclusions Vaginal microecological detection plays an important role in predicting the therapeutic effect of simple VVC.For the patients with lower lactobacillus counts,the follow-up after treatment should be strengthened.(Chin J Lab Med,2018, 41:292-295)
ABSTRACT
The evaluation of vaginal microecology has certain advantages in the accurate and rapid diagnosis of single vaginitis and mixed vaginal infections,which can reduce the rates of missed diagnosis and misdiagnosis.Moreover, this evaluation can guide the application of vaginalmicroeclogial modulators after treatment for vaginitis.At present, the currentevaluation of vaginal microecology is mainly based on morphology mainly, and supplemented by functional testing.However, functional testing needs regulation and quality control,and further clinical research is needed for the diagnosis of vaginal infections based on microbial metabolites alone.(Chin J Lab Med,2018,41:256-258)
ABSTRACT
Objective: To study the curative effect of adhesive intestinal obstruction with integrated traditional Chinese and western medicine. Methods: A total of 128 patients with adhesive intestinal obstruction were randomly divided into 2 groups ( 64 patients in each) . The western medicine group was treated with conventional therapies. Traditional Chinese and western medicine group received acupuncture and moxibustion on the basis of western medicine treatment. After 3 days, abdominal X?ray plain film examination was done. The recovery of gastrointestinal function, cure rate, hospitalization days and cost was compared. Results: The symptom alle?viation rate of abdominal pain and distension, nausea and vomitting, and exhaust and defecation in Chinese and Western medicine group were higher than those in western medicine group ( P<0?05) . The cure rate was higher than that in western medicine group ( P<0?05). Hospitalization days and cost were lower than those in western medicine group (P<0?01). Conclusion: Compared with treatment with western medicine, it has quick effect, high cure rate, short treatment course, low cost in the treatment of adhesive intestinal obstruction with integrated traditional Chinese and western medicine and acupuncture.
