ObjectiveThe clinical features, bacteria distribution and antibiotic resistance proifle of blood stream infection(BSI) were investigated in the patients with decompensated liver cirrhosis for better management of such infections.MethodsThe clinical data of BSI were collected in the patients with decompensated liver cirrhosis between January, 2012 and December, 2014, and reviewed retrospectively in terms of risk factors, diagnosis and treatment, pathogen distribution and prognosis.ResultsOf the 1 071 patients with decompensated liver cirrhosis and suspected bacterial infection, 154 (14.4%) were diagnosed as BSI evidenced by blood culture. Of these patients, the leukocyte count in the peripheral blood was higher than 10×109/L in only 48 (31.2%) patients; neutrophil proportion>0.75 in 133 patients (86.4%); serum procalcitonin level>0.5 ng/mL in 74 patients (68.5%). A total of 155 bacterial strains were isolated, including 115 strains of gram-negative bacilli and 40 strains of gram-positive cocci. Most patients (68.8%) recovered and 31.2% died or discharged from hospital voluntarily. All these BSI patients had Child-Pugh grade C liver function. Some patients also had other serious systemic diseases or repeated hospitalization.ConclusionThe prevalence of BSI is high in the decompensated liver cirrhosis patients with poor prognosis. Gram-negative bacilli are the major pathogens of such septicemia. Early diagnosis and proper use of antibiotics based on antimicrobial susceptibility testing are important to improve patient outcome.

Objective To investigate the drug-resistance of Staphylococcus aureus induced by erythromycin in vitro and its changes in growth and susceptibility of antibiotics.Methods Erythromycin in vitro induction was conducted with the S.au-reus reference strain ATCC25923 on the serial of erythromycin agar plates.The growth of S.aureus,and the susceptibility a-gainst other antibiotics was compared after induced to the parent strain.Results Resistance to erythromycin was successful-ly,and themaximum MIC was over 256 mg/L.The Erythromycin-resistant S.aureus grew much slower than the susceptible parent,and the strains didn’t have cross-resistance to other antibiotics.Conclusion S.aureus could be induced resistance in vitro by erythromycin,and this resistance inherited stably.Some phenotype and biochemical characteristic features of the strain were changed after induced.

AIM: To study the effect of cholecystokinin octapeptide(CCK-8) on lipopolysaccharide (LPS)-stimulated pulmonary interstitial macrophage(IM) in vitro. METHODS: Pulmonary IM were isolated and cultured in the presence of LPS, CCK-8, proglumide(the antagonist of CCK receptors) and vehicle alone or together. The expression of mCD14 protein was assayed by flow cytometry, and sCD14 in the supernatant was analyzed semi-quantitatively by Western blot, and TNF-? in the supernatant was detected with ELISA. RESULTS: CCK-8, at concentrations from 10 -7 mol/L to 10 -6 mol/L inhibited significantly the expression of mCD14, the release of sCD14 and TNF-? to the supernatant up-regulated by LPS(1 mg/L). The effect of CCK-8 was inhibited by proglumide. CONCLUSION: CCK-8 modulated negatively several functions of LPS-stimulated pulmonary IM through CCK receptors, which may be one of the mechanisms for CCK-8 to alleviate the inflammation in lung tissues during endotoxemia.

Objective: To study the expression and distribution of filaggrin (FLG) in oral submucous fibrosis (OSF) and to explore the significance of FLG in the occurrence and development of OSF. Methods : Ten cases with a normal oral mucosa (normal buccal mucosa group) and 30 cases of tissues with OSF lesions, including 10 cases each in the early (early OSF group), moderate (middle OSF group) and advanced stages (late OSF group), were selected. FLG was analyzed by immunohistochemistry. The FLG-positive cells were counted to calculate the percentages of cells with FLG-positive expression in each group. Results: FLG expression was negative in most of the normal buccal mucosa group specimens and was positive in the OSF buccal mucosal epithelial specimens. With aggravation of the OSF lesion, the number of FLG-positive cells increased. In the early OSF group, FLG-positive expression was mainly concentrated in the granular and keratinized epithelial layers. In the middle OSF group, the number of FLG-positive epithelial cells increased gradually. In the late OSF group, almost all epithelial cells were FLG-positive in the cytoplasmic nucleus. The percentages of FLG-positive cells in the early, middle and late OSF groups were (24.63 ± 9.06)%, (54.23 ± 10.63)% and (83.97 ± 8.72)%, respectively. The percentage of FLG-positive cells was significantly higher in the OSF group than in the normal mucosa group (P < 0.05). Conclusion FLG was expressed at a higher level in the OSF epithelium than in the normal oral mucosal epithelium and was upregulated in the OSF epithelium with aggravation of the OSF lesions. Abnormal FLG expression may be related to the terminal differentiation disorder of OSF epithelial keratinocytes.
