Fasting serum samples of all the subjects were collected. After removal of high-abundance protein, followed by proteolysis, peptide labeling and fractionating, the samples were then processed by mass spectrometry. The protein with TMT data of three groups was obtained and protein with TMT value 0 were removed. Heat map of protein was constructed. The differential protein was defined as the protein fold change over 1.5 or less than 0.67. The Reactome database was used to cluster the pathways of differential proteins among groups. Statistical methods included t test, hypergeometry test and corrected by BH multiple test. \u0000 \u0000 \u0000Results \u0000A total of 357 serum proteins were identified by proteomic profiling. There were 27 differential proteins between the IC group and the NC group, including six up-regulated proteins and 21 down-regulated proteins. There were 228 differential proteins between the UC group and the NC group, including 75 up-regulated proteins and 153 down-regulated proteins. There were 49 differential proteins between UC group and IC group, including 22 up-regulated proteins and 27 down-regulated proteins. In the comparison of differential proteins between the NC group, IC group and UC group, only the expression of fibrin 3 was statistically significant (the fold change between UC and NC, between UC and IC, between IC and NC were 0.24, 0.46 and 0.53, respectively; t=-5.089, -7.298 and -3.919, all P<0.01). The results of pathway cluster analysis showed that in the comparison of differential proteins between IC group and NC group, only the platelet degranulation pathway was enriched, and 10 proteins were involved in this pathway (P<0.01). In the comparison of differential proteins between UC group and NC group, there were 58 pathways enriched, of which 38 proteins were involved in the platelet degranulation pathway, 16 proteins were involved in the initial complement trigger pathway, 13 proteins were involved in the complement cascade pathway, and 11 proteins were involved in antibody-mediated complement activation pathway (all P<0.01). In the comparison of differential proteins between UC group and IC group, three different pathways were obtained. Among them, nine proteins were involved in the platelet degranulation pathway, seven proteins were involved in the initial complement trigger pathway, and five proteins were involved in the complement cascade pathway (all P<0.01). \u0000 \u0000 \u0000Conclusions \u0000The difference in serum proteome between I","PeriodicalId":10009,"journal":{"name":"中华消化杂志","volume":"91 1","pages":"840-845"},"PeriodicalIF":0.0,"publicationDate":"2019-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82301687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to the results of colonoscopy, 3 895 patients with colorectal adenoma and 11 232 healthy controls were enrolled. Multivariate logistic regression was used to analyze the correlation between overweight (body mass index (BMI) 24.0 to 27.9 kg/m2), obesity (BMI≥28.0 kg/m2) and the risk of colorectal adenoma. \u0000 \u0000 \u0000Results \u0000After adjusting for gender and age, compared with that of individuals with normal weight (BMI 18.5 to 23.9 kg/m2), the risk of colorectal adenoma of obese patients increased by 36% (odds ratio (OR)=1.36, 95% confidence interval (CI) 1.18 to 1.56). After stratifing by gender, compared with that of individuals with normal weight, the risk of colorectal adenoma of obese males increased by 30% (OR=1.30, 95%CI 1.07 to 1.59), the risk of colorectal adenoma of overweight females and obese females increased by 15% (OR=1.15, 95%CI 1.01 to 1.31) and 40% (OR=1.40, 95%CI 1.14 to 1.71), respectively.

The duration of treatment were both 10 days. Liver and renal functions were examined within three days after therapy. 13C or 14C-urease breath test was performed one month after the medication withdrawal. The patients were followed up once every two weeks during the treatment period. The medication and adverse reactions were recorded in detail. The compliance and rates of adverse events in two groups were compared and analyzed. The eradication rates of the two groups and subgroups were compared by intention-to-treat (ITT) and per-protocol (PP) analyses. The cost-effectiveness of the two groups was evaluated with cost effectiveness analysis (CEA). The cost/effectiveness (C/E) ratio was calculated by PP.

The samples including ascites, sputum and blood were collected and cultured. Distribution and drug resistance of pathogens were analyzed. Chi-square test and logistic regression analysis were used for analyzing the risk factors related to SAP complicated with infection. \u0000 \u0000 \u0000Results \u0000The total infection rate of SAP was 49.09% (215/438), of which the bacterial infection rate was 44.29% (194/438) and the fungal infection rate was 22.60% (99/438). A total of 625 pathogens were cultured, including 333 (53.28%) strains of Gram-negative bacteria, 171 (27.36%) strains of Gram-positive bacteria and 121 (19.36%) strains of fungi. Gram-negative bacteria were extremely resistant to β-lactams antibiotics, among them Acinetobacter baumannii was the highest (63.93% to 100.00%), and resistance rate to enzyme inhibitors was slightly lower (11.54% to 48.15%). The resistance rates of Gram-positive bacteria to penicillin and erythromycin were both high, which were 92.86% to 100.00% and 81.25% to 95.00%, respectively, and Gram-positive bacteria resistant to vancomycin, linezolid, and tigecycline were not found. The resistance rate of fungi was generally low (0 to 28.57%).

The varices were classified according to the endoscopic morphology and the etiology treatment, therapeutic efficacy and prognosis were also analyzed.

Etiological analysis showed that the primary disease of 34 cases (63.0%) were hepatogenic, 11 cases (20.4%) were pancreatic origin, and nine cases (16.7%) were from other diseases. As to treatment, three cases (5.6%) were treated with adhesive, two cases (3.7%) were treated with sclerotherapy, and 49 cases (90.7%) were treated with combination of adhesive and sclerotherapy. Therapeutic efficacy evaluation showed that 46 cases (85.2%) were significantly effective, eight cases were effective, 0 case was ineffective, and all the 54 cases (100.0%) were improved. The prognostic analysis showed that 35 cases (64.8%) had no bleeding in five years and eight cases (14.8%) had no bleeding in 10 years.

The patients were divided into gastric cancer (GC) group, atrophic gastritis (AG) group and non-atrophic gastritis (NAG) group. The positive expression rate of plasma circulating mSEPT9 of the three groups were detected by polymerase chain reaction (PCR) fluorescence probe method, its correlation with clinicopathological characteristics of gastric cancer were analyzed and also compared with the positive rate of carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9).

The positive rate of plasma mSEPT9 of GC group was higher than those of AG group and NAG group (46.9%, 69/147 vs. 4.8%, 4/83 and 3.9%, 5/127), and the differences were statistically significant (χ2=43.438 and 63.912, both P<0.016). The sensitivity and specificity of plasma mSEPT9 in patients with gastric cancers were 46.9%(69/147) and 95.7%(201/210), respectively. The positive rate of mSEPT9 was higher in gastric cancer patients with tumor maximum diameter over 5.0 cm, intestinal-type gastric cancer in Lauren classification, lymphatic metastasis, vascular and neurological invasion, middle-late stage (stage Ⅲ and Ⅳ) in clinical classification, which were 57.6% (38/66) vs. 35.6% (26/73), 52.6%(51/97) vs. 31.0% (13/42), 53.0% (61/115) vs. 25.0% (8/32), 55.6% (65/117) vs. 13.3% (4/30), 50.8% (65/128) vs. 4/19 and 53.5% (61/114) vs. 24.2% (8/33), respectively; and the differences were statistically significant (χ2=6.728, 5.517, 7.905, 17.091, 5.871 and 8.998, all P<0.05).
