Objective:To explore the effects of different courses of Bifidobacterium combined with bismuth on the eradication rate, ulcer healing rate and adverse reactions in the initial eradication treatment of Helicobacter pylori positive gastric ulcer patients.Methods:From September 2018 to September 2021, 219 patients with gastric ulcer were selected from the outpatient department of gastroenterology department of Kailuan General Hospital Affiliated,all of whom were positive for 13C or 14C-urea breath test and were not treated with Helicobacter pylori eradication. Group A, B and C were randomly divided by Excel, Group A was the control group (73 patients): 14-day bismuth quadruple therapy (Eprazole + colloidal bismuth pectin + amoxicillin + furazolidone); group B (73 patients): 7 days Bifidobacterium tetravaccine tablets (live) was given in the second week of treatment in group A; group C (73 patients): Bifidobacterium tetravaccine tablets (live) was given 14 days on the basis of treatment in group A. 13C or 14C-urea breath test and gastroscope were reexamined after all treatments, to compare the eradication rate, ulcer healing rate and the incidence of adverse reactions.Results:The eradication rates in three groups were 90.8%(59/65), 91.2% (62/68)and 91.0%(61/67) respectively, there was no significant difference among the three groups (χ 2=0.01, P=0.997). The ulcer healing rate in three groups were 93.8%(61/65), 94.1%(64/68) and 95.5%(64/67) respectively, group B and group C were compared with group A, and the difference was not statistically significant(group B: group A P=1.000, group C: group A P=0.716).The incidence of adverse reactions in three groups was 21.4%(15/70), 7.1%(5/70) and 7.0%(5/71) respectively, the difference was statistically significant (χ 2=9.21, P=0.010). The incidence of adverse reactions in group B and C was significantly lower than that in group A (group B: group A χ 2=5.83, P=0.016; group C: groups A χ 2=5.99, P=0.014). Compare means of measurement data among the three groups use analysis of variance. Chi square test, Fisher exact probability method and split chi square test were used to compare the three groups of counting data. Conclusion:14-day Bifidobacterium tetravaccine tablets (live) and the second half of the treatment lasted for 7-day Bifidobacterium Bifidobacterium tetravaccine tablets (live), they are combined separately with bismuth quadruple therapy in the first eradication of Helicobacter pylori positive gastric ulcer patients can significantly reduce adverse reactions, but Bifidobacterium tetravaccine tablets (live) could not significantly improve the eradication rate, and had no promoting effect on the healing of gastric ulcer.

Objective:To analyze the clinical characteristics of pertussis cases diagnosed by two pathological detection methods: bacterial culture and real-time polymerase chain reaction (RT-PCR), and to explore the applicable value of two pathological detection methods in the diagnosis of pertussis.Methods:Bilateral nasopharyngeal swabs and clinical information of 165 children suspected of pertussis were collected by Hebei Children′s Hospital from April 2019 to January 2020. The bacterial culture and RT-PCR for nasopharyngeal swab specimens were performed in all cases. Chi-square test was used to analyze the cases of pertussis diagnosed by the above two methods.Results:Based on clinical diagnosis, the sensitivity of bacterial culture and RT-PCR for the diagnosis of pertussis was 61.70% (58/94) and 86.17% (81/94), and the specificity was 92.96% (66/71) and 71.83% (51/71), respectively. The positive rate of RT-PCR in children of all ages, seasons and cough courses is higher than that of bacterial culture. Children with pertussis diagnosed by bacterial culture and RT-PCR were basically similar in age, season, and cough course distribution, with the most common cases ≤3 months old, a high incidence trend in summer and autumn, and the course of coughing in children was mostly within 15-21days. The positive rate of bacterial culture in the diagnosis of pertussis in children is affected by the age of the children, and there are statistical differences between children in different age groups (χ2= 11.929, P=0.036). The positive rate of bacterial culture was the highest in children with >3 years old (51.85% [14/27]), followed by children with ≤3 months old (48.72% [19/39]), and the lowest in children with >6-12 months old (15.00% [3/20]). Moreover, the positive rate of bacterial culture in the diagnosis of pertussis in children is also affected by the cough course of the children, and there are statistical differences between children in different cough course groups (χ2=9.841, P=0.020). The positive rate of bacterial culture was the highest in children with cough course 15-21 days (49.23% [32/65]), followed by 43.59% (17/39) in children with cough course 8-14 days, and the lowest in children with cough course of less than 7 days (22.86% [8/35]). Conclusions:Compared with RT-PCR, bacterial culture has lower sensitivity and higher specificity in the detection of pertussis. These two detection methods have their own advantages and limitations. Medical institutions at all levels should comprehensively analyze different laboratory detection methods. Only by combining the two methods can the diagnostic value and level be effectively improved.

Objective: To evaluate the reliability and validity of Chinese version of the Hypertensive Intracerebral Hemorrhage Empowerment Scale-Short Form (C-HICHES-SF). Methods: A total of 207 hypertensive intracerebral hemorrhage patients treated in the Department of Neurology inpatients of a three-grade hospital in Tianjin from August 2017 to January 2018 were selected by convenient sampling method. Chinese Diabetes Empowerment Scale-Short Form (C-DES-SF) was adapted into C-HICHES-SF by expert enquiry and the patients were surveyed. SPSS 24.0 and AMOS 24.0 were used for data processing. Results: C-HICHES-SF contains 8 items. Its Cronbach α was 0.833, Sperman's half-reliability was 0.797, Guttman's half-reliability was 0.742, test-retest reliability was 0.787, content validity was 0.943. one common factor was extracted by exploratory factor analysis, and could explain 52.36% of the variance contribution.the confirmatory factor analysis revealed a good fit of the model to the date based on various fit indices (χ²/df ratio=1.172, GFI=0.997, AGFI= 0.949, NFI= 0.980, CFI=0.980, TLI=0.994, RMSEA=0.029). Conclusion C-HICHES-SF has fewer articles and easy to use. It has good reliability and validity in patients with hypertensive intracerebral hemorrhage, It can be used as an effective tool to measure empowerment ability.
