Objective To investigate the effect of alprostadil injection on serum tumor necrosis factor ( TNF-α) ,β2-microglobulin (β2-MG) and soluble interleukin 2 receptor (sIL-2R) levels in adjunctive treatment of patients of severe hepatitis with liver and kidney syndrome.Methods A total of 60 patients of severe hepatitis with liver and kidney syndrome were collected and randomly divided into experimental group and control group with 30 cases in each group.The two groups were treated by conventional therapy, patients in the control group were treated by continuous renal replacement therapy, patients in the experimental group were treated on the basis of the control group with alprostadil injection in adjuvant therapy for 3 weeks.The serum biochemistry and liver and kidney function and clinical curative effect were detected.Results Compared with the control group, the serum TNF-α, β2-MG and sIL-2R levels of the experimental group were lower (P<0.05); alanine aminotransferase (ALT), aspartate aminotransferase (AST) and total bilirnbin (TBiL) levels were lower (P<0.05), albumin (Alb) level and prothrombin time activity (PTA) were higher (P<0.05), serum creatinine (Scr), urea nitrogen (BUN), CysC and 24h urine protein were lower (P<0.05), 24h urine volume was higher (P<0.05); efficacy in experimental group was better than control group (Z=-2.321,P=0.020).Conclusion Alprostadil injection in adjunctive treatment of severe hepatitis with liver and kidney syndrome patients has significant effect and high safety, could significantly reduce the serum TNF-α, β2-MG and sIL-2R levels.

Objective To discover the vital role of Rab27B in tumor cells and its potential molecular mechanism by means of quantitative proteomics analysis of Rab27B knockdown in MHCC97H.Methods The expression of Rab27B in MHCC97H cells was knocked down by the combination of Tet-on advanced inducible expression system and RNA interference technology.Then, proteins extracted from the cells were identified by LC-MS/MS system after FASP digestion and iTRAQ 4-plex labeling. Finally, the properties of differentially expressed proteins, including the subcellular localizations, biological processes and molecular functions, were analyzed by the bioinformatics method.Results There were 448 differentially expressed proteins (|Ratio|>1.21, P<0.05) identified in MHCC97H cells after Rab27B knock-down.The expression levels of 229 or 219 proteins were positively or negatively correlated with Rab27B, respectively. These differentially expressed proteins were mainly involved in vesicle transport, macromolecule localization, cellular response to stimulus.Furthermore, there were 26 differentially expressed proteins participating in 8 tumor-related signal pathways, eleven of which were in the focal adhesion signal pathway.Conclusion The analysis of quantitative proteomics in Rab27B-knockdown MHCC97H cell line by iTRAQ suggests that Rab27B not only has an impact on the exosomal secretion of tumor cells, but also regulates master proteins in signal pathways involved in cell proliferation and migration.

Objective To study the pathological and ultramicrostructural characteristics of organ tissues in relation to the clinical course of severe acute respiratory syndrome (SARS). Methods Post-mortem tissue samples of organs (lungs, heart, liver, spleen, kidneys, pancreas, stomach ) were obtained by needle biopsy from four SARS patients who died in middle and late stages 3-5 weeks after the onset of the disease. The pathological samples were studied by light and electron microscope, immunohistochemistry, histochemistry and indirect immuno-fluorescent antibody test. Results The main pathological features were early interstitial pulmonary fibrosis or organizing pneumonia. Fibroblasts were increased in the interalveoli septa and young connective tissue was found to fill the alveoli. Diffuse alveolar damage (DAD) with alveolar pneumocytes proliferation and an increase in macrophages were found. Desquamative alveolitis also existed at the same time. Squamous metaplasia and syncytial giant cells with multinuclei could be seen. CD3 + and CD20 + lymphocytes were markedly decreased and CD68 + macrophages and S-100 + dendritic cells increased in spleen. Proliferation of bone marrow cells became restrained . Hepatocytes were vacuolated with fatty degeneration. Electron microscopy showed the presence of coronavirus-like particles 80-60nm in diameter enveloped in the cytoplasm of the type Ⅱ pneumocytes, endothelial cells and lymphocytes. Conclusions A novel coronavirus is the cause of the newly recognized severe acute respiratory syndrom (SARS). The main target organs are lung and immune system. Different pulmonary pathological features were found in patients dying from the disease in different stages. All of specimens showed positive reaction of SARS-fluorescence antibody.

Objective To investigate the significance of lactate dehydrogenase(LDH) in the diagnosis and treatment of children with refractory Mycoplasma pneumoniae pneumonia(RMPP).Methods This was a study of children with Mycoplasma pneumoniae pneumonia(MPP) admitted to hospital from June 2013 to June 2016.All patients were treated with erythromycin.Based on the definition of RMPP,subjects were divided into usual MPP group and RMPP group.The children in RMPP group were treated with erythromycin combined with methylprednisolone.The indicators including LDH,WBC counts,C-reactive protein,erythrocyte sedimentation rate(ESR),alanine aminotransferase(ALT),aspartate amino ransferase(AST) and creatine kinase were analyzed between RMPP group and usual MPP group.The differences of the above indicators between the effective and ineffective group before and after methylprednisolone treatment were also compared.Results In total,253 subjects were enrolled,including 161 in the usual MPP group and 92 in the RMPP group.The average age in RMPP group was older than that in the usual MPP group.The indicators(including LDH,AST,ALT,and ESR) of RMPP group were higher than those in the usual MPP group.Logistic regression showed that LDH and ESR were the significant factors in predicting RMPP.The odds ratio(OR) of LDH was 1.029 with 95%CI 1.020-1.037,and the OR of ESR was 1.063 with 95%CI 1.009-1.120.Receiver operating characteristic curve analysis showed that the area under the curve of LDH(400.50U/L) was the largest(0.959,95%CI 0.936-0.983).The administration of methylprednisolone to patients in the RMPP group resulted in the rapid improvement of symptoms and decrease in serum LDH and ESR levels in effective group(P＜0.05).Conclusion Serum LDH may be used as a biomarker to predict RMPP at the early stage,also may be an important marker for the evaluation of therapeutic efficacy in RMPP.

Hypermetabolism syndrome,especially in skeletal muscles,is exceedingly common in septic patients.Many studies suggest that the activity of ubiquitin-proteasome pathway is a vital procedure for hypermetabolism of skeletal muscles of septic patients and its activation can be influenced by a variety of factors,such as proinflammatory cytokine and glucocorticoid,etc.Evidences indicate that insulin has played an important role in opsonizing the activation of ubiquitin-proteasome pathway.This paper reviews the regulation effect of insulin to the hypermetabolism of the skeletal muscles of septic patients through ubiquitin-proteasome pathway.
