OBJECTIVE: To compare the eradication rate, adverse reactions and compliance of the two 14-day bismuth-containing quadruple therapies in Liaoning Province as the first-line Helicobacter pylori(HP) eradication programs. METHODS: We collected222 eligible HP-infected patients who were admitted to the First Affiliated Hospital of China Medical University from March 2017 to October 2018 and treated with either of the following two programs:(1) EBLA group: esomeprazole(20 mg, twice a day), bismuth(200 mg, twice a day), levofloxacin(200 mg, twice a day) and amoxicillin(1 g, twice a day), 111 cases in total;(2) EBCA group:esomeprazole(20 mg, twice a day), bismuth(200 mg, twice a day), clarithromycin(500 mg, twice a day) and amoxicillin(1 g, twice a day), 111 cases in total. The patients in both groups were given medicines for 14 days, and the 13 C breath test was performed after4 weeks of withdrawal. RESULTS: The eradication rate of EBLA group was 87.34%(95%CI 80.9%-93.9%), and that of EBCA group was 83.33%(95%CI 76%-90.7%).There was no significant difference between the two groups(P=0.413). The incidence of adverse reactions was 10.8% in EBLA group and 26.13% in EBCA group. The difference was statistically significant(P=0.003). The compliance of patients in EBLA group was 99.10%, and that of EBCA group was 98.20%. The difference was not statistically significant(P=0.561).CONCLUSION: Both EBLA program and EBCA program can achieve good eradication rate and compliance in Liaoning province. The incidence of adverse reactions in EBLA group is lower than that in EBCA group, which is the preferred first-line HP eradication program.

Objective To evaluate the injuries in Jiangyou Field Hospital first week after Wenchuan earthquake,and accumulate experience for better medical services and better-built field hospitals to meet the demands of the earthquake-stricken areas.Methods Classification was performed in 1 905 patients with emergency treatment.The medical records of those with hospital stay were retrospectively analysed,including geographical distribution,trauma type,diagnosis,initial treatment and outcomes.Results Six hundred and twenty-nine(33%)patients were hospitalized,with an average of 2 to 100 years old(median,41.2).Three hundred and eighty-four patients(61%)were admitted within the first three days after earthquake.The patients were mainly from Jiangyou City(245,39%),Beichuan County(194,31%)and Pingwu County (158,25%).The most common types of injuries were superficial lacerations(326,51.8%),fractures(202,32.1%) and soft tissue contusions/sprains(87,13.9%),among whom 15 experienced severe squeeze.There were 318 injuries to pelvis and extremities(50.6%),117 to head(18.6%)and 43 to back(6.8%),and 73 cases had multiple injuries (11.6%).Of 376 patients(59.8%)with operation,326 received debridement,21 external fixation,19 internal fixation, 11 amputation,4 laparotomy,4 fasciotomy and 2 craniotomy.The incidence of postoperative infections was 11.8%.Death occurred in 39 patients due to cerebral trauma,pelvic fracture,abdominal hemorrhage and multiple injuries.Conclusion When the earthquake has destroyed the major medical facilities,rapid organization of medical rescue teams,making full use of remaining medical resources and recovering electricity play an important role in the rescue of victims and reduction of mortality.Orthopaedic surgeons must dominate the medical teams as most of the earthquake victims suffer from injuries to the extremities.
