OBJECTIVE: To analyze the incidence, clinical characteristics and prognosis of sepsis-related liver injury(SELI). METHODS: The data of septic patients in the department of Critical Care Medicine of the First Affiliated Hospital of China Medical University from January 2013 to December 2014 were collected and the basic information, infection site, emergency operation and residence were recorded. Also, the duration of ICU, the first 24 h APACHE II and SOFA score, mechanical ventilation, MODS, nutritional support, serum total bilirubin and aminotransferase, the duration of liver dysfunction and the duration of liver dysfunction during ICU stay were recorded. Rank sum test was used to compare age, APACHE II score, SOFA score, length of stay in ICU, duration of mechanical ventilation; Chi square test was used to compare the patient's source, type of operation, whether MODS, and nutritional support; The logistic regression analysis was used to analyze the related factors of death. RESULTS: A total of 341 septic patients with sepsis were included in the study, including 96 patients with septis-related liver dysfunction. The main manifestations were elevated transaminase in 17 cases(17.71%), elevated bilirubin in 31 cases(32.29%), elevated bilirubin and transaminase in 48 cases(50%) and liver injury in 66 cases(68.75%) of sepsic patients occurred within 1-3 days of ICU 3.22 days(1-40 days). The morbidity and mortality of MODS in sepsis-related liver injury patients were 70.83% and 33.33%. Statistically differences in APACHE II scores, SOFA scores, mechanical ventilation duration, and MODS in patients with different prognosis were revealed. Further logistic regression analysis showed that sepsis with MODS was an independent risk factor for death. There were statistical difference in duration of symptoms, duration of ICU stay and prognosis. CONCLUSION: The morbidity of SELI is high, mostly in the early stage of sepsis, men are more prone to the disease. The abdominal cavity is the most common site of infection. High APACHEII score, prolonged mechanical ventilation and MODS are independent risk factors for SELI.

Objective To study the molecular mechanism of interleukin 25 (IL-25)expression in the lung of asthmatic rats.Methods The expressions of IL-25 mRNA and protein in the lungs were detected by Real-time PCR and ELISA,respectively.The levels of IL-25 mRNA and protein were detected by ovalbumin (OVA)in human bronchial epithelial cells.And the transcription factors that regulate IL-2 5 expression were explored through site prediction.Results The expressions of IL-25 mRNA and protein in the lung of OVA-induced asthma rats were significantly increased during animal experiments.Cell experiments showed that OVA could increase the expression of IL-2 5 in human bronchial epithelial cells in a dose-dependent manner,and OVA could upregulate the expression of transcription factor AP1.AP1 was found in the promoter region of IL-25 by site prediction.The AP1 inhibitor (T5224)significantly reduced the expression of IL-25 in OVA-induced human bronchial epithelial cells. Conclusion The molecular mechanism of IL-25 expression induced by OVA in asthma is related to the increase of transcription factor AP1 .

OBJECTIVETo find out association mapping of loci related to schizophrenia on chromosome 1 with microsatellite markers in DNA pooling samples from schizophrenic cases and normal controls in Shandong peninsula.

METHODSA total of 31 microsatellite markers on chromosome 1 spaced at approximately 10 cM were scanned to two separated DNA pooling samples consisting of 119 schizophrenic cases and 119 normal controls respectively. Statistic analysis was performed by Chi-square test method to compare the difference between the ratio of each allele between the two pooling samples.

RESULTSSignificant statistic difference was found at D1S2878 between cases and controls, and P< 0.01 at this loci.

CONCLUSIOND1S2878 locus on chromosome 1 associates with schizophrenia in Shandong peninsula. Fine mapping and searching for candidate genes are warranted in this region.

The biological characterization, differentiation and regeneration of hepatic stem/progenitor cells are the one of very active and interested fields. In this report, intravenous injection of human umbilical cord blood (HUCB) cells into the BALB/c-nu and SCID mice, an animal model for transplantation and liver injury, was reported. Using of flow cytometry and tissue typing (HLA), it was found that the HUCB cells were survived in mouse liver for 9 weeks. After separation from perfused liver, HUCB cells were detected by hematopoietic colonies (CFU-GEM M) in hepatocyte culture. It was concluded that the transplanted HUCB hematopoietic stem/progenitor cells can be survived in the liver over a long period of time.

Objective To investigate the clinical features of patients with acute ST-segment elevation myocardial infarction (STEMI) comorbid with diabetes mellitus (DM) and to analyze the prognosis within 12 months after primary percutaneous coronary intervention (pre-PCI). Methods A total of 375 STEMI patients were divided into the diabetes group (n=140) and the normal blood glucose group(n=235) according to whether they met the diagnostic criteria of DH. The clinical data,characteristics of coronary artery lesions,type of stent implant,rate of coronary slow flow or no-reflow after pre-PCI, and the prognosis within 12 months after PCI of the two groups were investigated.Results Patient in the diabetes group presented with higher mean age ,higher comorbid rates of hypertension , hyperlipidemia and heart function of Killip class Ш and above than patients in the normal blood glucose group (all P<0.05). patients in the diabetes group had higher rates of slow reflow /no-reflow after PCI(12.9% vs.5.5%,P=0.013),higher percentages of 3-ressel disease(40.7% vs. 28.9%,P=0.019)and lef t main lesions(13.6% vs. 7.2%,P=0.044). The in-hospital mortality rates(6.4% vs.1.7%,P=0.020),revascularization rates within 12 months(7.9% vs.0.9%,P=0.001)and incidence of heart failure(7.9% vs. 2.6%,P=0.017)were all higher in the diabetes group. Conclusions STEMI patients comorbid with DM were relatively older, had higher comorbidities of hypertension,hyperlipidemia, three-vessel disease, left main coronary lesions and higher mortality during hospitalization. No significant increase in cardiac death and recurrent myocardial infarction were deserved during the follow-up period. These patients may benefit more from early intervention.
