Objective To explore the effect of postasphyxial-serum in neonate on expression of serine protease Omi/HtrA2 in renal tubular cells(HK-2).Methods Human renal proximal tubular cell line HK-2 cell was used as target cell.The cultural cells in orifice were divided into control group and asphyxia-serum attacking group.Blood was cowected from asphyxia newborns by means of femoral venous puncture,then the serum was garthered,anticoagulated by liquemie,3 000 r/min centrifuged 20 min,abstracted serum,thermostatic waterbathed the serum at 56 ℃,so that to inactivate addiment,filtered germ by micropore filte,the attacking concentrtion of serum was 200 mL/L,the cells of the asphyxia-serum attacking group were attacked by asphyxia-serum,and the cells of control group were cultivated with normal nutritive medium when the cells was needed.After 24 hours,the cells were tixed,then the expression of Omi/HtrA2 in cytoplast was detected by the use of immunohistochemical method.Results Omi/HtrA2 was inaurate or yellow brown and localized to the cytoplast.The rate of the cell expressed Omi/HtrA2 was(9.0?2.5)% in control group,after stimulated with postasphyxial-serum,in asphyxia group the rate of the cell expressed Omi/HtrA2 was(25.15?3.5)%,there was significant difference between 2 groups(t=-15.322 P

Reverse transcriptase-PCR experiments suggest that the two clusters of genes potentially involved in the oxidation of reduced sulfur compounds are organized as operons in strain of the acidophilic, chemolithoautotrophic bacterium Acidithiobacillus ferrooxidans ATCC 23270, the two clusters of genes including such the ORF of putative sulfate-thiosulfate-molybdate binding proteins, the ORF of putative thiosulfate: quinone oxidoreductase and the ORF of the rhodanese-like protein (P21). Bioinformatic analyses have predicted the possible promoters sequences and the possible +1 start site of transcription for the doxDA operons.

Objective To explore the culturing strategies,curiculum provision,courses conferring methods,teaching effects as well as the associated managerial evaluations on the basis of Sino-French cooperation on medical education with the hope of summarizing helpful suggestions to Sino-Foreign cooperation on medical education. Methods The achievements of our Sino-French cooperation on medical education were analyzed and compared in the teaching models,culturing strategies along with courses conferring processes among seven-year medical students from both English-teaching and French-teaching classes. Results Our Sino-French cooperation on medical education was featured in its distinct culturing purposes and effective teaching model.Its scientifically formulated culturing strategy found its full expression in French-teaching atmosphere.The Sino-French cooperation on medical education was consistently welcomed and favorably recommended by both faculties and students. Conclusion The Sino-French cooperation on medical education has not only gained precious experience in culturing the cutting-edge medical talents with the international visions but also conduced to fulfill the goal to establish a modernized and internationalized medical school.

OBJECTIVEKawasaki disease (KD) is a febrile illness of childhood. The etiology of KD remains unknown. Multiple theories exist, including an infectious etiology and an immunological abnormality. Cardiac involvement ranges from myocarditis and pericarditis in the acute stage to the development of coronary artery aneurysms later in the course. The present study aimed to explore the effect of monocyte chemotactic protein-1 (MCP-1) in Kawasaki disease and its relationship with damage to the coronary arteries during the development of KD.

METHODSPlasma MCP-1 concentrations were measured by enzyme-linked immunosorbent assay (ELISA), and MCP-1 mRNA expression in peripheral blood mononuclear cells (PBMC) was measured by quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) in comparison of three groups: 56 patients with KD, 60 age-matched patients with non-infectious diseases, and 66 age-matched febrile patients with various diseases.

RESULTSPlasma MCP-1 concentration and MCP-1 mRNA expression in PBMC of patients with active KD [(409.55 +/- 97.42) pg/ml] and (1.97 +/- 0.77) were higher than those of control group. Plasma MCP-1 levels and MCP-1 mRNA expression of inactive KD group [(301.64 +/- 71.55) pg/ml] and (1.31 +/- 0.39) were significantly higher than those of non-infectious diseases patients. There was a marked increase in patients with inactive KD than those of non-infective patients, but there were no significant differences between inactive KD and febrile patients. Plasma MCP-1 levels and MCP-1 mRNA expression were markedly increased in KD patients with coronary artery lesions than those in patients without coronary artery lesions.

CONCLUSIONPlasma MCP-1 concentration and MCP-1 mRNA expression in PBMC were significantly increased in patients with KD, and they were higher in KD with coronary artery lesions. It indicates that MCP-1 may be a useful parameter for monitoring disease activity in patients with KD.

OBJECTIVEThis study examined the expressions of plasma stromal cell derived factor-1 (SDF-1) and CXCR4 mRNA in peripheral blood mononuclear cells (PBMC) of children with Kawasaki disease (KD) and aimed to explore the significance of SDF-1 and CXCR4 mRNA in KD.

METHODSFifty-six children with KD (12 cases complicated by coronary artery lesions) and 60 age and gender-matched healthy children (normal controls) were enrolled in this study. Plasma SDF-1 levels and CXCR4 mRNA expression in PBMC were measured using ELISA and real-time quantitative PCR at the acute and convalescence stages of KD.

RESULTSPlasma SDF-1 levels (1833 +/- 395 ng/L vs 1126 +/- 408 ng/L; P < 0.05) and the CXCR4 mRNA expression in PBMC (6.57 +/- 2.81 vs 2.58 +/- 1.01; P < 0.01) in KD patients were significantly higher than those in normal controls at the acute stage. Both plasma SDF-1 levels and CXCR4 mRNA expression in KD patients decreased significantly at the convalescence stage, but nevertheless remained higher than those in the normal controls. The patients with concomitant coronary artery lesions showed higher CXCR4 mRNA levels than without at the acute stage (8.19 +/- 2.39 vs 6.13 +/- 2.77; P < 0.05).

CONCLUSIONSPlasma SDF-1 concentration and CXCR4 mRNA expression in PBMC increased in KD patients. CXCR4 mRNA might be involved in the development of coronary artery lesions in KD.

Objective To explore the clinical characteristics, pathological features and prognostic factors of patients with acquired immune deficiency syndrome (AIDS) related lymphoma (ARL).Methods The clinical characteristics, treatment regimen and survival status were retrospectively analyzed.At a ratio of 1∶2, 106 general non-Hodgkin lymphoma (NHL) cases were included after matching for demography and clinical characteristics with 53 ARL patients.Chi-square test was used for statistical analysis.Overall survival was analyzed using Kaplan-Meier curves.Cox regression was used for multivariant analysis.Results The predominant pathologic type of ARL was diffuse large B cell lymphoma (60.4%, 32/53).B cell lymphoma accounted for 88.7% (47/53) and T cell lymphoma accounted for 11.3% (6/53).Patients in ARL group (62.3%, 33/53) had lower proportion of receiving radiotherapy or chemotherapy compared with patients in general NHL group (94.3%, 100/106) (χ2=26.58, P<0.05).ARL group had lower hepatitis B surface antigen (HBsAg) positivity rate compared with general NHL group (1.9% vs 26.4%, χ2=14.26, P<0.05).No other characteristic was found significantly different between these two groups.The survival time of ARL and general NHL patients was (6.0±1.3) months and (48.0±10.0) months, respectively (t=8.13, P<0.01).The 1-year, 2-year, 3-year and 5-year survival rates of ARL patients were 39.6%, 32.7%, 27.7% and 20.1%, respectively, while those of general NHL patients were 79.2%, 56.8%, 42.4% and 25.0%, respectively.Of the 33 ARL patients and 100 general NHL patients who received anti-NHL treatment, the 1-year survival rates were 60.6% and 83.0%, respectively (χ2=4.040, P=0.043), the 2-year survival rates were 53.5% and 60.5%, respectively (χ2=0.003, P=0.096), the 3-year survival rates were 48.1% and 45.9%, respectively (χ2=0.288, P=0.59), the 5-year survival rates were 39.1% and 27.5%, respectively (χ2=0.798, P=0.372).Multivariate analysis revealed that anti-NHL therapy and international prognostic index score were independent predictors for prognosis (both P<0.05).Conclusions Diffuse large B cell lymphoma is the predominant pathologic type of ARL.ARL patients has significantly lower survival rate compared with general NHL patients.Combination of anti-HIV therapy and anti-lymphoma therapy in individuals with ARL can prolong their survival time.
