The prevalence in China is increasing year by year, which can affect the quality of life of patients and also increase the economic burden on families and society. The pathogenesis of GERD is still unclear, and some studies suggest that intestinal microecology may be closely related to the development of GERD. Rifaximin is not readily absorbed orally and acts locally in the intestine, so it has mild adverse effects and good safety, and can be used to treat gastrointestinal diseases such as irritable bowel syndrome, traveler’s diarrhea, small intestinal bacterial overgrowth, diverticulosis, inflammatory bowel disease and hepatic encephalopathy. Therefore, this paper focuses on intestinal microecology as a possible pathogenesis of GERD and further explores the feasibility of rifaximin for the treatment of GERD.展开更多

The vaginal flora is in a state of balance, and the microorganisms coexist and are interdependent to maintain the vaginal micro-ecological balance, which is a kind of dynamic balance influenced by endogenous and exogenous factors. Vaginal infections are traditionally treated by killing microbes in the vagina. Given the extensive study of the internal vaginal environment, people become gradually aware of the significance of maintaining the vaginal micro-ecological balance rather than blindly using antimicrobial agents. The balance in the vaginal internal environment is disrupted during the gestation period as the secretion of progesterone increases. The imbalanced vaginal micro-ecological environment may lead to vaginal infectious diseases. This paper provides a review of the relationship between the vaginal microecology and infectious diseases during gestation period.展开更多

Methods: Female patients in the outpatient department and inpatient department of gynecology of our hospital from April 1, 2018 to August 23, 2021 were selected as the research objects. The reproductive tract secretions of all patients were examined by microecological examination, morphological examination, chemical analysis and microscopic examination, and the results of various indicators were statistically analyzed to draw relevant conclusions. Results: Among the 1498 women with vaginal micro- ecological imbalances, cleanliness was determined to be 534 cases of degree II, 868 cases of degree III, and 96 cases of degree IV;Nugent scores were 9 - 10 in 9 cases, 8 in 122 cases, 7 in 30 cases, 6 in 18 cases, 5 in 8 cases, 4 in 717 cases, 3 in 248 cases, 2 in 209 cases, 1 in 118 cases, and 0 in 19 cases. AV scores were 8 in 1 case, 7 in 1 case, 6 in 2 cases, 5 in 9 cases, 4 in 84 cases, 3 in 207 cases, 2 in 850 cases, 1 in 284 cases, and 0 in 60 cases. Among the pathogen infections, 99 cases were mycoplasma, 361 cases were candida, 199 cases were bacterial and 8 cases were trichomonas;In chemical analysis, there were 138 cases with pH 5.1, 326 cases with pH 4.8, 775 cases with pH 4.6, 217 cases with pH 4.4, and 42 cases with pH 4.1;meanwhile, 1390 cases were positive for hydrogen peroxide, 505 cases were positive for glucosidase, 487 cases were positive for acetylglucosaminidase, 184 cases were positive for sialidase, 290 cases were positive for proline amino-peptidase, 501 cases were positive for coagulase, and 1064 cases were positive for leukocyte esterase. Conclusion: Female reproductive tract microecology is more complex, and the pathogens of infection are also diverse. A systematic examination can clarify the occurrence and development of the disease, and then provide reliable laboratory data for clinical treatment and guide clinical medication.展开更多

Methods: Sixteen p SS patients were enrolled in the present study, who received 3-month treatment of YYHR, 200 mL orally twice daily. Their pre-and post-test ESSDAI scores, erythrocyte sedimentation rate(ESR) and serum immunoglobulin G(IgG) levels were measured respectively. The 16 Sr DNA metagenomic sequencing was used to detect and analyze the abundance and diversity of intestinal bacteria flora and the proportion of bacteria at the levels of phylum, family, and genus, in comparision with those of 6 healthy subjects in the control group. Results: The abundance and diversity of intestinal bacteria flora in pSS patients were lower than those of healthy subjects(P<0.05). After the treatment with YYHD, patients’ ESSDAI score and levels of IgG and ESR have decreased significantly(P<0.05). At the phylum level, the proportions of Actinobacteria, Firmicutes, Fusobacteria and Proteobacteria have reduced sharply, while the proportions of Bacteroidetes, Teneriquetes and Candidate-division-TM7 have increased significantly by treatment(all P<0.05). At the classification level, such treatment has caused a significant decrease in the proportions of Bacteroidaceae, Ruminococcaceae, Veillonellaceae, and Enterobacteriacea(all P<0.05), but a significant increase in the proportion of Lachnospiraceae(P<0.05). At the genus level, the treatment has significantly decreased the proportions of Bifidobacterium, Bacteroides, Escherichia-Shigella, Faecalibacterium and Prevotella(all P<0.05), but significantly increased the proportion of Clostridia(P<0.05), close to the levels of healthy subjects(P>0.05). Conclusions: There exists an imbalance of intestinal microecology in p SS patients, which can be improved through the treatment with YYHD. Besides, such treatment can also improve the disease activity and adjust the diversity of intestinal bacteria flora, the composition and the abundance of intestinal flora.展开更多

[Method]Basal diets in four test groups were added with 0. 015% oxytetracycline,0. 01% microecological preparation,0. 2% fulvic acid,and 0. 1% Chinese herbal medicine extract respectively,and laying hens in control group were fed with basal diets. Effect of four different additives on performance and egg quality were studied under the temperature of 28. 6℃. [Result]The average egg-laying rate and feed-egg ratio in groups 2,3 and 4 were significantly better than those in control group and group 1( P < 0. 05). The contents of fat and cholesterol in eggs in groups 2,3 and 4 were lower than those in control group and group 1. And the fat content of eggs in group 4 was 13. 42% lower than that in control group,the difference was significant( P < 0. 05). The protein contents in groups 2,3 and 4 were significantly higher than those in control group and group 1( P < 0. 05). [Conclusion] Microecological preparation,fulvic acid and Chinese herbal medicine extract could replace antibiotics to be applied in the production of laying hens.展开更多

Moreover, specially to set up double-control, including a thyroideum medicament and an empty test group, for the comparison and analysis. Our results show that the intestinal microecologics of eel, for increasing growth and rejuvenation to ossified eels, that are botth achieve striking effect. But looked the thyroideum for increasing growth to ossified eels were be very effective. Nevertheless, which for rejuvenation was failed to take effect.Furthermore, we inc-lined to believe that the could be possible still significance of effect, if again added intestinal obligate anserobes of adult eels, and the cerebiogen into this microecologics.展开更多
