AIM: To investigate the effects of psychological stress on ulcerative colitis rats and to explore the mechanisms of this;meanwhile to investigate the effects of anxiolytic drug on symptoms of ulcerative colitis rats under psychological stress and the mechanisms of it.METHODS: eighty male Wistar rats were randomly divided into four groups(n=20): UC control group;UC stress group;UC+clonazepam group;UC stess+clonazepam group.After UC model was established with immunization,these rats were fightened by cat to set up psychological stress model.During establishing stress model,each groups were respectively received physiologic saline or clonazepam by intragastric administration.After 15d treatment,all rats were sacrified simultaneously.Colon mucosal inflammationand damage were assessed by measuring colon mass,morphologic damage score,colonic MPO and NO activity levels.Morphologic damage score was examined under microscope.Colonic MPO and NO was measured by spectrophotometric method.Serum hydrocortisone was determined by radioimmunoassay(RIA).RESULTS: Morphologic damage score,colonic MPO and NO,serum hydrocortisone of UC stress group were significantly increased compared with those of UC control group;morphologic damage score,colonic MPO and NO,serum hydrocortisone of UC+clonazepam group were decreased markedly vs UC stress group;Little difference was observed between UC+clonazepam group and UC control group.CONCLUSION: Psychological stress can aggravate symptoms of UC.Although benzodiazepine have no anti-inflammatory action,it relieve effects on internal organs of psychological stress and aggravation of symptoms of UC by to effect limbic system and formatio reticularis.

This study was designed to use iTRAQ technology coupled with 2D LC-MS/MS to study the comparative proteomics of different processing technology for pilose antler. 1015 proteins were identified with 2D LC combined with MOLDI TOF/TOF mass spectrometry. Comparative analysis with Protein Pilot (Version 4.5) revealed that 87 proteins were changed (P ≤ 0.05, the ratio of > 1.50 or < 0.60 as the threshold selection of difference proteins), of which 24 were up regulated and 33 were down regulated in the traditional frying process (TFP) compared with the fresh pilose antler (P ≤ 0.05). 7 significant different proteins (P ≤ 0.001), most of these significantly changed proteins were found to be involved in calcium ion binding and ATP binding associated with human healthy. Freeze drying with protective agent (FDP) (Trehalose) can improve the content of significantly different proteins (P ≤ 0.001) including Collagen alpha-1 (XII) chain (COL12A1) and Collagen alpha-1 (II) chain (COL2A1). The significant function involves in platelets activating, maintenance of spermatogonium, and disorder expression in tumor cells. The functional annotation by Hierarchical clustering and GO (gene ontology) showed that the main molecule functions of the proteins significantly changed in these processes were involved in binding (52.7%), catalytic (25.3%), structural molecule and transporter (6.6%).

This study was aimed to determine the solubility an d oil-water partition coefficient of main active com-ponents in Ge-Gen Qin-Lian (GGQL) Tablets (puerarin, baicalin and berberine hydrochloride) in phosphate buffer solution of different pH values and under the background of many components. Solubility of puerarin, baicalin and berberine hydrochloride in different medium pH, and oil-water partition coefficient of the octanol-water and oc-tanol-buffer system were determined by HPLC method. The results showed that the solubility and oil-water partition coefficient of puerarin, baicalin and berberine hydrochloride were varied with the change of pH, and varied under the background of components. At pH 7.4, the solubility was the biggest;puerarin was 7.56 mg·mL-1;baicalin was 17.07 mg·mL-1; berberine hydrochloride was 3.57 mg·mL-1. Oil-water partition coefficient P of these components at pH 1.0 was bigger;puerarin was 0.420 (lgP=-0.38);baicalin was 10.783 (lgP=1.03);berberine hydrochloride was 0.267 (lgP=-0.57). It was concluded that lipid solubility of puerarin, baicalin and berberine hydrochloride at pH 1.0 was better. It was speculated that better absorption in the stomach, and low lipid solubility under other pH. It was speculated that lipid solubility may be one of the reasons affecting the intestinal absorption.

Objective:To understand the vancomycin dose, therapeutic drug monitoring(TDM) situation and therapeutic effect of children after liver transplantation.Methods:A retrospective analysis of the data of 98 children who received intravenous vancomycin treatment after liver transplantation were conducted in the Department of Critical Care Medicine of Beijing Friendship Hospital from January 2017 to June 2019, including demographic data, vancomycin dose, serum trough concentration, drug-related adverse reactions and clinical outcome data.Results:A total of 98 children received intravenous vancomycin treatment and at least one steady-state TDM blood sample was collected.Among them, 53 cases (54.1%) were male, and the median age was 9 months(5 months to 14 years old). The median first daily dose of vancomycin treatment was 50(30-60)mg/(kg·d), and the median duration of treatment was 14(3-54)days.Only 27.5%(27/98)of the children′s initial trough concentration reached the target concentration (10-20 mg/L), while 26 cases(26.5%) did not reach the target after adjusting the treatment.Six children(6.1%)had renal toxicity caused by vancomycin, and two children had skin rash.The effective treatment rate accounted for 51.7%(15/29). The initial trough concentrations of vancomycin in the effective and ineffective groups were(5.92±3.82)mg/L and(10.43±5.37)mg/L, respectively.The difference was statistically significant ( P=0.041). Conclusion:The rate of intravenous vancomycin in children after liver transplantation is low, and the dose needs to be adjusted individually.

Inhalation of crystalline silicon dioxide particles can induce silicosis, and the development of silicosis is closely related to the occurrence and development of pulmonary inflammation and pulmonary fibrosis. NOD-like receptor thermal protein domain associated protein 3 (NLRP3) inflammasome has been established as a major proinflammatory receptor for sensing environmental danger signals. Activation of NLRP3 inflammasomes after phagocytosis of silicon dioxide particles by pulmonary macrophages may be an important mechanism to induce oxidative stress and sustained inflammatory response in the lung. This article summarizes the role of NLRP3 inflammasome in the inflammatory response and pulmonary fibrosis in silicosis, and analyzes it as a potential target for silicosis treatment.

Objective:To analyze the phenotypic and genomic characteristics of Salmonella isolates recovered from meat products in Beijing wholesale markets. Methods:A total of 336 Salmonella strains from meat products collected from wholesale markets in Beijing were tested for antimicrobial resistance to 25 antimicrobial compounds by micro-broth dilution method; whole genome data were sequenced, followed by the serotype and ST type prediction by Seqsero2 and SISTR software, and the drug resistance genes and virulence factors were also predicted with CARD and VFDB databases of Abricate software; Salmonella serotyping assay kit and serum agglutination method were used for serotype confirmation of some isolates with different genome prediction results. Results:The resistance rates to Nalidixic acid and Ampicillin were 62.5% (210/336) and 55.1% (185/336), respectively, and all isolates were susceptible to Tigecyclin, Cefoxitin and Carbapenem antimicrobial compounds; 207 isolates (61.6%, 207/336) were multi-drug resistant, some could even be resistant to ten categories of drugs at the same time, and the most common antimicrobial resistance spectrum was NAL-AMP-SAM. A total of 24 serotypes were detected with predominant serotypes of Enteritidis (34.5%, 116/336), Derby (17.3%, 58/336) and Indiana (10.4%, 35/336). A total of 27 ST types were detected, the dominant type was ST11; ST types were in good consistency with serotypes; The detection rates of resistant genes referred to aminoglycosides, fluoroquinolones, β-lactams, sulfonamides and tetracyclines are more than 48%, and the first two reached 100%. The prediction of drug resistance genes was consistent with the results of antimicrobial resistance phenotype. A total of 122 virulence genes were predicted, 74 of which existing among all isolates.Conclusion:Salmonella in meat from the wholesale markets of Beijing has a high proportion of multiple drug resistance, a complex drug resistance spectrum, a variety of serotypes and ST types, and a high carrying rate of drug resistance gene and virulence gene; drug resistance phenotype and genotype are relatively consistent.
