【摘要】:研究目的本課題旨在利用16SrDNA分析鼻腔菌群結(jié)構(gòu),探討鼻淵舒口服液作為清膽泄熱法的代表方在治療膽腑郁熱證慢性鼻-鼻竇炎方面的作用機(jī)制。研究方法將符合標(biāo)準(zhǔn)的12例膽腑郁熱型慢性鼻-鼻竇炎患者及9例健康正常人納入組取其中鼻道分泌物,并予以慢性鼻-鼻竇炎病人組華神集團(tuán)生產(chǎn)的鼻淵舒口服液,每日3次,每次1支,2周治療結(jié)束后再次取同側(cè)中鼻道分泌物。利用16SrDNA克隆文庫(kù)測(cè)序分析法檢測(cè)各組鼻腔細(xì)菌菌群結(jié)構(gòu)表達(dá)情況。最后經(jīng)統(tǒng)計(jì)學(xué)分析,得出結(jié)論。研究結(jié)果慢性鼻-鼻竇炎病人組中樣品最大shannon指數(shù)為1.406,Simpson指數(shù)最小為0.213,服用鼻淵舒口服液后的鼻竇炎患者組中最大shannon指數(shù)為0.453,simpson指數(shù)最小為0.103,健康正常人的shannon指數(shù)最大為0.952,Simpson指數(shù)最小為0.15。慢性鼻-鼻竇炎患者組的鼻腔菌群多樣性較健康正常人高,服用鼻淵舒口服液治療后的慢性鼻-鼻竇炎患者鼻腔菌群多樣性有所降低,較健康正常人低。鼻竇炎病人組的菌群結(jié)構(gòu)為Staphylococcaceae占67.53%, Enterobacteriaceae占22.34%,Streptococcaceae占5.87%,Pseudomonadaceae占0.91%,Oxalobacteraceae占0.28%,Xanthomonadaceae占0.21%。服用鼻淵舒治療后的鼻竇炎病人組菌群比例為Enterobacteriaceae占95.28%,Staphylococcaceae占3.24%、Streptococcaceae占0.93%,其余細(xì)菌均未達(dá)到0.1%。健康正常人組菌群比例為Staphylococcaceae占96.12%,Enterobacteriaceae 占 0.85%, Streptococcaceae占0.51%,其余細(xì)菌均未達(dá)到0.1%。結(jié)論①慢性鼻-鼻竇炎患者較正常健康人鼻腔菌群多樣性高,二者菌群比例有所不同,但優(yōu)勢(shì)菌都為Staphylococcaceae,推測(cè)慢性鼻-鼻竇炎發(fā)病是條件致病菌引起的。②服用鼻淵舒口服液治療后的慢性鼻-鼻竇炎患者的菌群多樣性減少,優(yōu)勢(shì)菌群的科屬發(fā)生改變,推測(cè)鼻淵舒口服液治療慢性鼻-鼻竇炎的作用機(jī)制在于改變鼻腔內(nèi)環(huán)境,調(diào)整鼻腔菌群結(jié)構(gòu),抑制條件致病菌生長(zhǎng)。
[Abstract]:Objective to investigate the mechanism of Biyuanshu oral liquid in treating chronic rhinosinusitis with chronic rhinosinusitis by 16SrDNA. Methods 12 patients with chronic rhinosinusitis and 9 healthy controls were included in the study group. The nasal secretions were collected from the patients with chronic rhinosinusitis and were treated with Biyuanshu oral liquid produced by Huaxin Group, a group of patients with chronic rhinosinusitis. After 2 weeks of treatment, the secretion of middle nasal canal was collected again 3 times a day. The expression of bacterial flora in nasal cavity was detected by sequencing analysis of 16SrDNA clone library. Finally, by statistical analysis, draw a conclusion. Results the maximum shannon index of samples in patients with chronic rhinosinusitis was 1.406 and the minimum was 0.213. The maximum shannon index of sinusitis patients after taking Biyuanshu oral liquid was 0.453 and the minimum was 0.103. The shannon index of healthy people was the highest. Dawei 0.952 Simpson index minimum 0.15. The diversity of nasal microflora in patients with chronic rhinosinusitis was higher than that in healthy subjects, and the diversity of nasal flora in patients with chronic rhinosinusitis was lower than that in healthy subjects after treatment with Biyuanshu oral liquid. In sinusitis group, the microflora structure was Staphylococcaceae (67.53), Enterobacteriaceae (22.34) and Streptococcaceae (5.87). Pseudomonadaceae was 0.91% and Oxalobacteraceae was 0.280.28%, Xanthomonadaceae was 0.21%. The proportion of bacteria in patients with sinusitis treated with Biyuanshu was 95.2828. Staphylococcaceae was 3.24 and Streptococcaceae was 0.93.The other bacteria did not reach 0.1. In healthy people, the proportion of bacteria in Staphylococcaceae was 96.12, 0.85 in Enterobacteriaceae, 0.51in Streptococcaceae, none of the other bacteria had reached 0.1. Conclusion (1) the diversity of nasal flora in patients with chronic rhinosinusitis is higher than that in normal controls. But the dominant bacteria were Staphylococcaceae. it was speculated that the incidence of chronic rhinosinusitis was caused by opportunistic bacteria. 2. The diversity of bacteria in patients with chronic rhinosinusitis treated with Biyuanshu oral solution was decreased, and the family and genus of dominant bacteria were changed. It is inferred that the mechanism of Biyuanshu oral liquid in treating chronic rhinosinusitis lies in changing the intranasal environment, adjusting the structure of nasal flora and inhibiting the growth of conditioned pathogens.
