Objective To explore the effects of aspirin on formation and dispersion of Pseudomonas aeruginosa (P.aeruginosa) biofilm.Methods The broth microdilution method was used to detect the minimal inhibitory concentration(MIC) of aspirin for P.aeruginosa.The anti-biofilm effects of aspirin on P.aeruginosa were determined on the microtiter plates combined with crystal violet staining.The serial dilution method for counting colony number on microtiter plate was used to explore the effects of aspirin on initial adherence of P.aeruginosa.Results The MIC values of aspirin against PAO1,PA18,PA53 and PA67 strains of Pseudomonas aeruginosa were 5,2.5,5 and 5 mg/mL respectively.Aspirin significantly inhibited the formation and dispersion of the biofilm of PAO1 and PA18 strains (t =5.65,P ＜ 0.05 and t =5.06,P ＜ 0.05 for inhibition;t =6.45,P ＜ 0.05 and t =6.26,P ＜ 0.05 for dispersion) at the concentration of 2.5 mg/mL.Similar effects were also found in the determination for PA67 and PA53 strains(t =6.45,P ＜0.05 and t =6.26,P ＜ 0.05 for inhibition;t =7.82,P ＜ 0.05;t =9.18,P ＜ 0.05 for dispersion) at aspirin concentration of 1.25 and 0.313 mg/mL respectively.Aspirin inhibited the initial adherence of P.aeruginosa at the concentration of 2.5 mg/mL(P ＜0.05).Conclusion Aspirin could significantly inhibit the initial adherence and biofilm formation of P.aeruginosa and disperse the 24 hour-formed mature bioiflm.

Objective To investigate the correlation between the transport time of preterm infants with respira-tory failure and the clinical outcome. And to determine the transit time in critically ill premature infants. Methods Premature infants in level Ⅱ neonatal ward in Hunan Province Children's Hospital from January 1 to December 31, 2013,admitted to the Neonatal Intensive Care Unit requiring respiratory support(invasive and noninvasive),were re-viewed. All the patients were classified into non - standardized transport group and regulate transport group according to respiratory support that infants in the level Ⅱ neonatal ward required. Data on general information,the time of ventilator application,the time of exposure to oxygen,morbidity of bronchopulmonary dysplasia(BPD),the cure and improvement rate,length of stay,the total length of stay(length of stay in the local hospital and our hospital),and hospitalization ex-penses were collected. Results Among the 363 infants,there were 107 cases in the non - standardized transport group, and 256 cases in the regulate transport group. The time of ventilator application in the non - standardized transport group was longer than that in regulate transport group[(19. 75 ± 19. 53)d vs(13. 02 ± 12. 64)d,t = 18. 706,P ﹤ 0. 05],the time of exposure to oxygen was longer[(30. 60 ±24. 80)d vs(19. 50 ±19. 24)d,t =6. 883,P ﹤0. 05],the morbidity of BPD was higher[57. 01%(61/ 107 cases)vs 18. 36%(47/ 256 cases),χ2 = 53. 934,P ﹤ 0. 05],but the cure and im-provement rate was lower[70. 10%(75/ 107 cases)vs 83. 20%(213/ 256 cases),χ2 = 7. 912,P ﹤ 0. 05],and the total length of stay was longer[(59. 50 ± 34. 02)d vs(34. 48 ± 23. 69)d,t = 22. 967,P ﹤ 0. 05]than that in the regulate group. But there was no significant difference between the length of stay[(43. 99 ±28. 08)d vs(32. 79 ± 23. 76)d,t =2. 012,P ﹥0. 05]in the non - standardized transport group and regulate transport group,with the hospitalization expenses [(6. 55 ±4. 30)vs(4. 99 ±4. 12)thousands yuan,t =0. 552,P ﹥0. 05]. Conclusions The non - standardized transport group has higher morbidity of BPD,but lower cure or improvement rate,and it has longer length of stay. The 2013 edition of Chinese Neonatal Ward Hierarchical Construction and Management Guide(Proposal)is reasonable,level Ⅱ neonatal ward should be in strict accordance with it to transport regional neonatal.

According to the association between liver injury and pregnancy, liver diseases during pregnancy can be classified as pregnancy-specific liver diseases and liver diseases with pregnancy. Pregnancy-specific liver diseases refer to the liver diseases that only occur during pregnancy, while liver diseases with pregnancy refer to pregnancy with previous liver diseases. Due to the particularity of maternal and fetal health during pregnancy, the diagnosis and treatment of liver diseases during pregnancy is challenging for both obstetricians and hepatologists. Rapid identification, diagnosis, and treatment of related diseases during pregnancy are very important for the prognosis of the mother and the fetus. This article summarizes and reviews the research advances in the epidemiology, pathogenesis, clinical manifestations, diagnosis, treatment, and prognosis of liver diseases during pregnancy, in order to provide a reference for more clinicians.

Objective: To investigate the relationship between PET/CT metabolic parameters and pathological features and prognosis in esophageal squamous cell carcinoma (ESCC) patients with intramural gastric metastasis (IGM). Methods: Totally 86 cases of ESCC IGM patients treated in Anhui Provincial Hospital Affiliated to Anhui Medical University from January 2008 to December 2014 were selected for this study. The patients received the imaging examination by positron emission tomography and computed tomography (PET/CT). The metabolic parameters including maximum standard uptake value (SUVmax), metabolic tumor volume (MTV), PET tumor length (PTL) and mean standard uptake value (SUVmean) were examined to calculate the total lesion glycolysis (TLG). The survival of the patients during 5-year follow-up was recorded, and the relationship between metabolic parameters and clinical pathological features and prognosis was analyzed. Results: SUVmax and SUVmean of IGM patients were related to the diameter of the primary tumor (all P<0.05); MTV was associated with the tumor diameter, lymph node metastasis, and TNM staging (all P<0.05); TLG was associated with the tumor diameter, lymph node metastasis, TNM stage, and tissue differentiation (all P<0.05). During the 5-year follow-up, 6 patients were lost to follow-up, 36 patients died and 44 patients survived; SUVmax, MTV, TLG, PTL, SUVmean, and TNM staging were predictors for patients’prognosis (all P<0.05); MTV, TLG, PTL, SUVmean, and TNM staging were risk factors for prognosis (all P< 0.05). Conclusion: The metabolic parameters including SUVmax, MTV, TLG, PTL and SUVmean in ESCC patients with IGM are related to the pathological characteristics of patients; moreover, MTV, TLG, PTL, SUVmean and TNM staging are risk factors for prognosis; so, PET/CT examination has certain clinical value for the prognosis assessment in ESCC patients with IGM.

Great achievements have been made in the treatment of liver cancer in recent years. Inflammation plays an important role in the development and progression of liver cancer, while aspirin can exert an anti-inflammatory effect. Basic and clinical studies have found that aspirin can inhibit the development and progression of liver cancer, assist in the comprehensive treatment of liver cancer, and exert an anticancer effect together with other drugs. Aspirin has low costs and is easy to access, and its potential in the adjuvant therapy for liver cancer has attracted great attention; however, there are still many problems and confusions in the application of aspirin in clinical practice. This article summarizes and reviews the recent research advances in aspirin in the prevention and treatment of liver cancer, the problems faced at present, and the future development direction, in order to improve the understanding of this field and lay a foundation for clinical application in the real world in the future.
