[Effect of Biyanning Granules on local symptoms and immune function of chronic rhinosinusitis].

This study discusses the effect of Biyanning Granules on local symptoms and systemic immune function of patients with chronic rhinosinusitis with nasal polyps(CRSwNP) within the 6 months of treatment by glucocorticoid nasal spray after surgical treatment. To be specific, a total of 237 CRSwNP patients, treated in Otorhinolaryngology Head and Neck Surgery in Shanxi Bethune Hospital, were enrolled. All patients were treated by nasal endoscopy and classified into hormone group(Budesonide Nasal Spray after surgery), Chinese medicine group(Biyanning Granules after surgery), and combination group(Budesonide Nasal Spray+Biyanning Granules after surgery) with random number table method, 79 cases in each group, and the treatment lasted 3 months. The follow-up was performed from the day of discharge to 12 months after the surgery. The clinical effect was observed. The visual analogue scale(VAS) scores and sino-nasal outcome test-20(SNOT-20) scale scores were used to assess patient's subjective symptoms and quality of life. Lund-Kennedy endoscopic score(LKES), Japanese T&T olfactometry, and standard olfactory test were used to evaluate the objective curative effect on patients. The levels of interleukin(IL)-21, CD4~+CD25~+Foxp3~+Treg, and CD4~+Th17 in peripheral blood were analyzed. The incidence of complications, recurrence rate, and adverse reactions during treatment were also recorded. The total effective rate after treatment in the combination group was higher than that in the hormone group and Chinese medicine group(P<0.05). VAS scores and SNOT-20 scale scores were lower in the three groups after treatment than before treatment and lower in the combination group than in the other two groups(P<0.05). The improvement in LKES and T&T standard olfactometry test was better in the combination group than in the other two groups(P<0.05). Serum levels of IL-21 and CD4~+Th17 in the three groups were lower than before treatment. The levels in the combination group were lower than those in the other two groups and lower in the hormone group than in the Chinese medicine group(P<0.05). Serum CD4~+CD25~+Foxp3~+Treg level was higher in the three groups after treatment than before, higher in the combination group than in the other two groups, and higher in the Chinese medicine group than in the hormone group(P<0.05). During the treatment, no serious adverse reactions were observed. After treatment, the combination group showed no significant difference in the incidence and recurrence rate of complications from the hormone group and Chinese medicine group. In the treatment of CRSwNP with glucocorticoid, Biyanning Granules reduced the side effects of glucocorticoid and assisted glucocorticoid in alleviating the symptoms of patients. It significantly improved the curative effect, regulated immune imbalance, accele-rated the recovery of immune function, reduced the recurrence rate of inflammatory reaction, and improved the quality of life. The combination of Chinese and western treatment is more effective than glucocorticoid alone and warrants further clinical study in large sample size.

[Detection of diarrheagenic escherichia coil harboring genomic O island 28 isolated from children diarrhea in Taiyuan].

OBJECTIVE: To investigate the etiologic value of diarrheagenic E. coil harboring genomic O island 28(OI-28) containing five putative virulence genes (Z0608, Z0609, Z0615, Z0634 and Z0635), which were related to RTX (Repeat in toxin) toxin family isolated from children with diarrheal disease in Taiyuan. METHODS: In the study, 257 fecal samples from children with diarrheal disease collected in Shanxi Children's Hospital. Diarrheagenic E. coli and enteropathogenic bacteria were isolated and identified by conventional bacterial culture and typing specific diarrheagenic E. coli (EPEC, EIEC, ETEC and EHEC) diagnostic serum, while diarrheagenic E. coli harboring genomic 01-28 containing five putative virulence genes (Z0608, Z0609, Z0615, Z0634 and Z0635) were detected by PCR and DNA southern blot hybridization. RESULTS: 206 strains (80.16%) of enteropathogenic bacteria were detected from 257 children with diarrhea disease, containing 149 strains (57.98%) of diarrheagenic E. coli and 57 strains(22.18%) of other entero-pathogenic bacteria. Among 3 strains (2.01%) of EPEC, 2 strains (1.34%) of ETEC, 2 strains (1.34%) EHEC were detected by typing specific serum, while all of the 142 strains (95.30%) isolated were suspected to be diarrheagenic E. coli. 21 strains (14.09%) of diarrheagenic E. coil harboring genomic O1-28 containing five putative virulence genes (Z0608, Z0609, Z0615, Z0634 and Z0635) were detected by polymerase chain reaction and DNA southen blot hybridization, 8 strains (5.37%) of diarrheagenic E. coli containing only one genomic OI-28 virulence gene, 2 strains (1.34%) of diarrheagenic E. coli containing two genomic OI-28 virulence gene. 21 children with diarrhea diseases caused OI-28-harboring E. coli containing five important putative virulence genes were among 0 to 3 years old (80.95%). These children correlating with OI-28-harboring E. coli did not present special clinical symptoms or signs. CONCLUSION: The diarrheagenic E. coil harboring genomic OI-28 was one of the important etiology for children with diarrheal disease in summer season.
