Abstract
AIM To assess the value of measurement of the gradient and ratio of ascites-serum tumor markers in the differential diagnosis of tuberculous ascites and malignancy-related ascites.
METHODS Sixty patients with ascites were divided into two groups, namely, 31 cases of malignant ascites and 31 cases of tuberculous ascites. Tumor markers in serum and ascites were simultaneously detected to calculate and compare the gradient and ratio of serum-ascites tumor markers between the two groups.
RESULTS The positive rates of CEA and CA199 in the malignant group were significantly higher than those of the tuberculosis group (P < 0.01). The positive rates of CA125 and α-fetoprotein (AFP) showed no significant difference between the two groups (P > 0.05). Ratio analysis of tumor markers in ascites and serum revealed that CA125, CA199, and CEA ratios were statistically significant between the two groups, with CA125 ratio having the most significant difference (P < 0.01). Ascites-serum gradient analysis showed that CA125, CEA, and CA199 gradients were significantly different between the two groups (P < 0.01). The ratio and gradient of AFP were not significantly different between the two groups (P > 0.05).
CONCLUSION At the cutoff values of CA125 ratio > 2.16, CA125 gradient > 264.05 ng/mL, CEA ratio > 4.8, CEA gradient > 23.05 ng/mL, CA199 ratio > 0.96, and CEA gradient > -0.20 ng/mL, the diagnostic value of combining the gradients and ratios of the three tumor markers are more helpful to distinguish tuberculous ascites and non-liver cancer ascites than any of the three markers alone.

Abstract
Endoscopic ultrasound (EUS) has significantly improved our understanding of the complex vascular structural changes in patients with portal hypertension. At present, EUS is a useful diagnostic tool for the evaluation of esophagogastric varices (EGVs) and guidance of endoscopic therapy. Several studies have employed this new technique for the diagnosis and management of esophageal and gastric varices, respectively. In the present review, we have summarized the current status of EUS for the diagnosis and management of EGVs and clarified the clinical feasibility of this procedure. New indications for EUS can be developed in the future after adequate validation.

Abstract
OBJECTIVES We evaluate the efficacy of concomitant therapy for Helicobacter pylori infection and the associated factors that influence it in China, where it has not previously been investigated. METHODS In this prospective study, 374 consecutive patients with H. pylori infection were randomly assigned to 10 day regimens of concomitant therapy with different proton pump inhibitors: esomeprazole (20 mg)/omeprazole (20 mg), amoxicillin (1000 mg), clarithromycin (500 mg) and metronidazole (400 mg). All drugs were administered twice daily. A [(13)C]urea breath test was performed at least 4 weeks after the completion of treatment. Gene polymorphisms and antimicrobial susceptibility were determined. RESULTS A total of 374 patients with active, uncomplicated duodenal ulcer disease were enrolled in the study (187 cases in each group). The overall eradication rate resulting from concomitant therapy was 90.7% (PP) and 86.1% (ITT) and the eradication rate was significantly higher in the group that received an esomeprazole-based regimen compared with the group that received an omeprazole-based regimen [95.4% versus 86.0%, respectively, P = 0.003 (PP) and 89.8% versus 82.4%, P = 0.036 (ITT), respectively]. Moreover, the omeprazole-based regimen was an independent risk factor for treatment failure (P = 0.039), as were CYP2C19 extensive metabolizer (P = 0.005), clarithromycin (P = 0.000) and metronidazole resistance (P = 0.000). In addition, CYP2C19 polymorphisms and antibiotic resistance had a synergistic effect on eradication rates. The majority of side effects were mild and none was serious. CONCLUSIONS The 10 day concomitant therapy yielded an eradication rate of nearly 90%. Antibiotic resistance, CYP2C19 polymorphisms and their interactions were closely associated with regimen efficacy.

Abstract
AIM: To evaluate the safety, efficacy and value of endoscopic intestinal stent placement in the treatment of colorectal cancer complicated with acute intestinal obstruction.
METHODS: A total of 263 patients with colorectal cancer complicated with intestinal obstruction treated at our hospital from January 2010 to December 2014 were included. Stenting treatment was performed under endoscopy and (or) X-ray. The rate of success, the incidence of postoperative complications, the rate of symptom remission, the rate of surgical excision and other indicators were evaluated.
RESULTS: Stent implantation was successful in 258 (98.1%) cases. The rates of adverse events were: perforation, 1.1% (3 cases); hemorrhage, 3.8% (10 cases); fever, 4.6% (12 cases), and others such as stent dislocation and migration, 3.0% (8 cases). The rates of symptom remission were: abdominal pain, 97.3% (256 cases); abdominal distension, 97.3% (258 cases); and anal dysfunction, 98.1% (258 cases). The rates of surgical resection were: 60 cases for palliative treatment, 198 cases for surgical resection 5-13 d after stent implantation after intestinal preparation, and 143 cases for removal of the tumor by one-stage operation.
CONCLUSION: The symptoms of intestinal obstruction can be relieved by endoscopic intestinal stenting. Emergency endoscopic stenting can be used as a bridge treatment before operation, and it can turn emergency operation to elective surgery, turn two-stage operation to one-stage operation, reduce the difficulty and risk of operation for clinicians, reduce the incidence of postoperative complications, relieve pain, and improve survival quality.

Propensity score-based survival benefit of simultaneous liver-kidney transplant over liver transplant alone for recipients with pretransplant renal dysfunction. Liver Transpl 2016; 22:71-9.

Abstract
The survival benefit of simultaneous liver-kidney transplantation (SLKT) over liver transplantation alone (LTA) is unclear from the current literature. Additionally, the role of donor kidney quality, measured by the kidney donor risk index (KDRI), in survival benefit of SLKT is not studied. We compared survival benefit after SLKT and LTA among recipients with similar pretransplant renal dysfunction using novel methodology, specifically with respect to survival probability and area under the survival curve by dialysis status and KDRI. Data were obtained from the Scientific Registry of Transplant Recipients. The study cohort included patients with pre-liver transplantation (LT) renal dysfunction who were wait-listed and received either a SLKT (n = 1326) or a LTA (n = 4283) between March 1, 2002 and December 31, 2009. Inverse Probability of Treatment Weighting-SLKT and LTA survival curves, along with the 5-year area under the survival curve, were computed by dialysis status at transplant. The difference in the area under the curve represents the average additional survival time gained via SLKT over LTA. For patients not on dialysis, SLKT resulted in a significant 3.7-month gain in 5-year mean posttransplant survival time. The decrease in mortality rate differs significantly by KDRI, and an estimated 76% of SLKT recipients received a kidney with KDRI sufficiently low for mortality. The mortality decrease for SLKT was concentrated in the first year after transplant. The difference between SLKT and LTA 5-year mean posttransplant survival time was 1.4 months and was nonsignificant for patients on dialysis. In conclusion, the propensity score-adjusted survival among SLKT and LTA recipients was similar for those who were on dialysis at LT. Although statistically significant, the survival advantage of SLKT over LTA was of marginal clinical significance among patients not on dialysis and occurred only if the donor kidney was of sufficient quality. These results should be considered in the ongoing debate regarding the allocation of kidneys to extra-renal transplant candidates.

Abstract
Background: In contrast to the consistent evidence for obesity and colorectal cancer (CRC) risk, the impact of obesity in CRC patients is less clear. In a well-characterised cohort of CRC patients, we prospectively evaluated class I and class II obesity with survival outcomes. Methods: The CRC patients (N=634) were followed from the date of diagnosis until disease progression/first recurrence (progression-free survival (PFS)) or death (overall survival (OS)). Body mass index (BMI) was calculated from reported usual weight prior to diagnosis. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated in models adjusted for clinicopathologic, treatment, and lifestyle factors. Results: Over a median follow-up of 4 years, 208 (33%) patients died and 235 (37%) recurred or progressed. Class II obesity, as compared with either overweight or normal weight, was associated with an increased risk of death (HR and 95% CI: 1.55 (0.97–2.48) and 1.65 (1.02–2.68), respectively), but no clear association was observed with PFS. In analyses restricted to patients who presented as stages I–III, who reported stable weight, or who were aged <50 years, obesity was associated with a significant two- to five-fold increased risk of death. Conclusions: In CRC patients evaluated at a large cancer centre, severely obese patients experienced worse survival outcomes independent of many other factors.

Abstract
Times between successive events (i.e., gap times) are of great importance in survival analysis. Although many methods exist for estimating covariate effects on gap times, very few existing methods allow for comparisons between gap times themselves. Motivated by the comparison of primary and repeat transplantation, our interest is specifically in contrasting the gap time survival functions and their integration (restricted mean gap time). Two major challenges in gap time analysis are non-identifiability of the marginal distributions and the existence of dependent censoring (for all but the first gap time). We use Cox regression to estimate the (conditional) survival distributions of each gap time (given the previous gap times). Combining fitted survival functions based on those models, along with multiple imputation applied to censored gap times, we then contrast the first and second gap times with respect to average survival and restricted mean lifetime. Large-sample properties are derived, with simulation studies carried out to evaluate finite-sample performance. We apply the proposed methods to kidney transplant data obtained from a national organ transplant registry. Mean 10-year graft survival of the primary transplant is significantly greater than that of the repeat transplant, by 3.9 months (p=0.023), a result that may lack clinical importance.

Abstract
BACKGROUND Respiratory syncytial virus (RSV) is a common community-acquired pathogen responsible for a substantial disease burden in adults. We investigated the outcomes after RSV infection in hospitalized adults over a 3-year period. METHODS This single-center, retrospective study identified 174 patients hospitalized with RSV upper or lower respiratory tract infection (LRTI) between January 1, 2009 and June 30, 2012. Clinical data were extracted from medical records. The primary outcome analyzed was all-cause mortality, defined as death during the index hospital admission. Subjects were divided into 3 groups for comparison: hematopoietic stem cell transplant (HSCT) patients, solid organ transplant (SOT) patients, and non-transplant patients. RESULTS In our study, 41/174 (23.6%) were HSCT recipients and 28/174 (16.1%) were SOT recipients. Twelve of 174 (6.9%) died. Death occurred in 2/41 (4.9%) HSCT and 3/28 (10.7%) SOT recipients, compared to 7/106 (6.6%) non-transplant patients. When compared to the non-transplant cohort, HSCT and SOT were not found to be significant risk factors for mortality (P = 0.685 and 0.645, respectively). In multivariate logistic regression, age >60 was associated with mortality (P = 0.019), while lymphopenia on admission trended toward an association with death (P = 0.054). HSCT patients were less likely to be admitted to an intensive care unit (odds ratio [OR] 0.26, P = 0.04), but were significantly more likely to receive ribavirin therapy (OR 11.62, P < 0.0001). CONCLUSION Adults hospitalized with RSV LRTI are at significant risk of mortality, and this risk may be increased in patients age >60 or with lymphopenia on admission. This study did not identify any significant increased mortality or morbidity associated with RSV infection in immune suppressed transplant recipients vs. patients who had not received a transplant.

Abstract
AIM: To explore the relationship between the change of reactive oxygen species (ROS) and DNA damage caused by Helicobacter pylori (H. pylori) infection in gastric epithelial cells.
METHODS: H. pylori ACTC43504 (CagA+, VacA+) infected GES-1 cells were used in this study. Live cell imaging system was used to observe the change of intracellular ROS, and a microplate reader was used to detect intracellular ROS level. Single cell gel electrophoresis comet assay was used to detect DNA damage.
RESULTS: ROS level was proportional to H. pylori concentration, and the ROS level was the highest when the MOI of H. pylori was 300:1. Various concentrations of N-acety-L-cysteine (NAC) could significantly inhibit the generation of ROS caused by H. pylori infection. H. pylori could cause DNA damage. After NAC pretreatment, the values of tail length, comet length, tail moment, and Olive tail moment had a clear downward trend compared with the H. pylori group.
CONCLUSION: H. pylori infection in GES-1 cells increases intracellular ROS level and results in DNA damage. Inhibition of the generation of ROS could reduce DNA damage.

Abstract
AIM: To evaluate the efficacy of furazolidone-based triple and quadruple therapy in eradicating Helicobacter pylori (H. pylori) in a multi-center randomized controlled trial.
METHODS: A total of 720 H. pylori positive patients with duodenal ulcer disease were enrolled at 10 different hospitals in Jiangxi province in China. The patients were randomly assigned to four treatment groups as follows: patients in Groups 1 and 3 received rabeprazole (10 mg), amoxicillin (1000 mg) and furazolidone (100 mg) twice daily for 7 and 10 d, respectively; patients in Groups 2 and 4 received rabeprazole (10 mg), bismuth (220 mg), amoxicillin (1000 mg) and furazolidone (100 mg) twice daily for 7 and 10 d, respectively. The primary outcome measure was H. pylori eradication rate 4 wk after treatment by intention-to-treat and per protocol analysis, while the secondary outcome measures were symptom and sign changes at the end of treatment and 4 wk after the end of treatment, as well as the proportion of patients who developed adverse events.
RESULTS: The demographic data of the four groups were not significantly different. Overall, 666 patients completed the scheme and were re-assessed with the 13C-urea breath test. The intention-to-treat analysis of the H. pylori eradication rates in Groups 1, 2, 3 and 4 were 74.44%, 82.78%, 78.89% and 86.11%, respectively. The H. pylori eradication rate in Group 4 was significantly higher than that in Group 1. According to the per protocol analysis, the H. pylori eradication rates in Groups 1, 2, 3 and 4 were 81.21%, 89.22%, 85.54% and 92.26%, respectively. The H. pylori eradication rate in Group 4 was significantly higher than that in Group 1. The number of adverse events was 15 (8.3%), 16 (8.9%), 15 (8.3%) and 17 (9.4%) in Groups 1, 2, 3 and 4, respectively, including dizziness, vomiting, diarrhea, nausea, skin rash, itchy skin, and malaise. The symptoms were relieved without special treatment in all of the patients.
CONCLUSION: Both 7- and 10-d quadruple furazolidone-based therapies achieve satisfactory H. pylori eradication rates.

Abstract
Dermatomyositis (DM) and polymyosits (PM) are systemic autoimmune diseases whose pathogeneses remain unclear. Neutrophil extracellular traps (NETs) are reputed to play an important role in the pathogenesis of autoimmune diseases. This study tests the hypothesis that NETs may be pathogenic in DM/PM. Plasma samples from 97 DM/PM patients (72 DM, 25 PM) and 54 healthy controls were tested for the capacities to induce and degrade NETs. Plasma DNase I activity was tested to further explore possible reasons for the incomplete degradation of NETs. Results from 35 DM patients and seven PM patients with interstitial lung disease (ILD) were compared with results from DM/PM patients without ILD. Compared with control subjects, DM/PM patients exhibited a significantly enhanced capacity for inducing NETs, which was supported by elevated levels of plasma LL-37 and circulating cell-free DNA (cfDNA) in DM/PM. NETs degradation and DNase I activity were also decreased significantly in DM/PM patients and were correlated positively. Moreover, DM/PM patients with ILD exhibited the lowest NETs degradation in vitro due to the decrease in DNase I activity. DNase I activity in patients with anti-Jo-1 antibodies was significantly lower than in patients without. Glucocorticoid therapy seems to improve DNase I activity. Our findings demonstrate that excessively formed NETs cannot be degraded completely because of decreased DNase I activity in DM/PM patients, especially in patients with ILD, suggesting that abnormal regulation of NETs may be involved in the pathogenesis of DM/PM and could be one of the factors that initiate and aggravate ILD.
