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 evaluate the safety and efficacy of percutaneous balloon pulmonary valvuloplasty (PBPV)in the treatment of the children with pulmonary stenosis (PS),and to observe the long - term prognosis and analyze the influencing factors. Methods The total of 230 children were collected,who had been diagnosed with pul-monary valve stenosis and had undergone percutaneous balloon pulmonary valvuloplasty between November 1987 and November 2015 in Shandong Provincial Hospital Affiliated to Shandong University. Their ages ranged from 4 months to 17 years,and the follow - up duration lasted from 1 month to 29 years. The data included clinical data and long - term follow - up data of hospitalized children,and the echocardiography data from the healthy peers in the same period. Then the data were analyzed statistically. Results In this study,228 cases of children were successfully performed PBPV, and the success rate was 99％(228 / 230 cases). The pulmonary transvalvular gradient (△P)of preoperation,24 hours postoperatively,half a year postoperatively,2 years postoperatively,5 years postoperatively,and 10 years postope-ratively was (63. 5 ± 23. 8)mmHg (1 mmHg = 0. 133 kPa),(26. 2 ± 11. 1)mmHg,(24. 8 ± 9. 8)mmHg,(20. 9 ± 8. 9)mmHg,(18. 1 ± 8. 7)mmHg,(15. 3 ± 7. 3)mmHg and (15. 3 ± 7. 3)mmHg,respectively. The immediate post-operative △P was significantly lower than that of preoperation (P < 0. 01),and the △P of the most children decreased in the long - term follow - up. The results of Logistic regression analysis showed that valve dysplasia with right ventricu-lar outflow tract stenosis and the immediate postoperative residual transvalvular gradient degree were the risk factors for long term curative effect of PBPV in children who could not reach the best standard. The restenosis rate was 4. 6％(3 /65 cases)with children followed up for more than 10 years. The incidence of long - term follow - up pulmonary valve regurgitation (83％)was significantly higher than that before operation (58％)and short term (68％)after operation, and the degree of regurgitation also increased (P < 0. 05),while the degree of regurgitation of the tricuspid regurgitation decreased gradually during the follow - up (P < 0. 05);the right ventricular diastolic diameter of the patients at 10 years or more after the operation was measured as (19. 27 ± 3. 03)mm,which was significantly higher than that (15. 24 ± 2. 89)mm of the healthy children of at the same term healthy age (P < 0. 05). Conclusions The PBPV has a high success rate in the treatment of children with PS,and it has good medium - long - term curative effect,less com-plications and lower restenosis rate. Therefore,PBPV can be used as the first choice for PS. However,the incidence and degree of pulmonary regurgitation has an increasing trend after PBPV and the right ventricular diastolic diameter is still larger than that of the healthy children. Therefore,the long - term follow - up is necessary out of the hospital.

Objective:To compare the long-term oncological outcomes between laparoscopic and abdominal surgery in stage Ⅰa1 （lymph-vascular space invasion-positive, LVSI +）- Ⅰb1 cervical cancer patients with different tumor sizes. Methods:Based on the Big Database of Clinical Diagnosis and Treatment of Cervical Cancer in China (1538 project database), patients with stage Ⅰa1 （LVSI +）-Ⅰb1 cervical cancer who treated by laparoscopic or abdominal surgery were included. The 5-year overall survival (OS) and 5-year disease-free survival (DFS) between the two surgical approaches were compared under 1∶1 propensity score matching (PSM) in different tumor diameter stratification. Results:(1) A total of 4 891 patients with stage Ⅰa1 （LVSI +）-Ⅰb1 cervical cancer who underwent laparoscopy or laparotomy from January 1, 2009 to December 31, 2016 were included in the 1538 project database. Among them, 1 926 cases in the laparoscopic group and 2 965 cases in the abdominal group. There were no difference in 5-year OS and 5-year DFS between the two groups before matching. Cox multivariate analysis suggested that laparoscopic surgery was associated with lower 5-year DFS ( HR=1.367, 95% CI: 1.105-1.690, P=0.004). After 1∶1 PSM matching, 1 864 patients were included in each group, and there was no difference in 5-year OS between the two groups （94.1% vs 95.4%, P=0.151）. While, the inferior 5-year DFS was observed in the laparoscopic group (89.0% vs 92.3%, P=0.004). And the laparoscopic surgery was associated with lower 5-year DFS ( HR=1.420, 95% CI: 1.109-1.818, P=0.006). (2) In stratification analysis of different tumor sizes, and there were no difference in 5-year OS and 5-year DFS between the laparoscopic group and abdominal group in tumor size ≤1 cm, >1-2 cm and >2-3 cm stratification (all P>0.05). Cox multivariate analysis showed that laparoscopic surgery were not related to 5-year OS and 5-year DFS ( P>0.05). In the stratification of tumor size >3-4 cm, there was no difference in 5-year OS between the two groups ( P>0.05). The 5-year DFS in the laparoscopic group was worse than that in the abdominal group (75.7% vs 85.8%, P=0.025). Cox multivariate analysis suggested that laparoscopic surgery was associated with lower 5-year DFS ( HR=1.705, 95% CI: 1.088-2.674, P=0.020). Conclusions:For patients with stage Ⅰa1 （LVSI +）-Ⅰb1 cervical cancer, laparoscopic surgery is associated with lower 5-year DFS, and the adverse effect of laparoscopic surgery on oncology prognosis is mainly reflected in patients with tumor size >3-4 cm. For patients with tumor sizes ≤1 cm, >1-2 cm and >2-3 cm, there are no difference in oncological prognosis between the two surgical approaches.
