In university research institutions,when in charge of several projects at the same time,the project leader will inevitably pay not enough attention to every project.In order to ensure the progress and quality of each research project,the study designs and builds project managercentered management mechanisms,redesigns the research and development structure from the system perspective,establishes the crossbar management model,and further analyzes the internal communication mechanism,the power-and-responsibility division mechanism,and oversight mechanism.

Objective To analyze the clinical feature,pathogenesis and treatment of autoimmune hemolytic anemia (AIHA) in patients after orthotopic liver transplantation.Method A retrospective analysis was conducted on 7 patients who developed AHA after orthotopic liver transplantation.The clinical feature,pathogenesis and treatment of AIHA were reviewed.Result The incidence of AIHA was 0.98％ (7/713).AIHA occurred (7.9-± 4.0) (3-14) days after transplantation.All patients were characterized by progressive anemia and jaundice.Laboratory examination showed lower hemoglobin and platelet count,higher lactate dehydrogenase,higher indirect bilirubin and higher reticuloeyte count.The causes of AIHA included ABO-incompatible liver transplantation,infection and repeated transfusion.Conclusion AIHA is a rare and serious complication after liver transplantation.The most cause is ABO-incompatible liver transplantation.The patients can be successfully cured if the diagnosis is clarified and the treatment is definitive.

Objective: To evaluate the clinical efficacy and safety of ticagrelor in the patients with acute coronary syndrome ( ACS) . Methods:A retrospective study was applied to investigate the ACS patients treated with ticagrelor in our hospital from July to December in 2015. The basic information of patients, drug administration, platelet aggregation induced by ADP, major adverse cardio-vascular events ( cardiac death,nonfatal myocardial infarction,target vessel revascularization and stent thrombosis) , and adverse drug reactions ( ADR) were recorded. The incidence of end point events was calculated and the change of platelet aggregation induced by ADP before and after the drug administration was analyzed by SPSS statistical software. Results:A total of 161 patients were collected. The incidence of cardiovascular adverse events was 1. 2%, while the incidence of adverse drug reactions was 30. 4% including bleeding (15. 5%) without severe bleeding events and dyspnea (10. 6%) with 3 severe ones. The platelet aggregation rate before and after the ticagrelor treatment respectively was (54. 96 ± 14. 654)%and(24. 37 ± 13. 183)% in 122 patients with low reaction to clopidogrel( P<0. 01). Conclusion:Ticagrelor at the recommended dose can further reduce the platelet aggregation induced by ADP. In spite of high incidence of ADR, ticagrelor has slight ADR with good tolerance.

The respiratory tract is constantly exposed to environmental elements so that pathogens invade the lung easily and induce infectious disease.Most microbes could be eliminated by innate immunity and adaptive immunity.In healthy host,but in immunocompromised hosts such as HIV infection,transplant recipients,cancer,collagen vascular disease and critical illness,the lungs are more susceptible to bacteria,fungal and virus.

Objective To investigate the effect of histone deacetylases-1(HDAC-1)siRNA on the HDAC-1 protein expression,cell growth and apoptosis in HeLa cells.Methods The HDAC-1 protein was knocked down by HDAC-1 siRNA.HDAC-1 protein was detected by Western blot.The cell growth inhibition was assesses by MTT and clone forming assay.Apoptosis was measured by flow cytometry.Results Forty-eight h after transfection of HDAC-1 siRNA,HDAC-1 protein expression in HeLa cells was down-regulated obviously.The down-regulation of HDAC-1 significantly reduced the colony formation rate,inhibited cell proliferation and induced apoptosis in HeLa cells.Conclusion HDAC-1 siRNA may play an anti-proliferation role in HeLa cells by inducing apoptosis.

Objective To compare clinical prognosis between intermittent high-volume predilution on-line hemofiltration (HF) and standard intermittent hemodialysis (HD) in critically ill patients with acute kidney injury (AKI).Methods This was a prospective,randomized,controlled single-centre clinical study.The mortality and recovery rate of kidney function were compared in critically ill adult patients with AKI between HF group (using intermittent high-volume predilution on-line HF,50 cases) and HD group (standard intermittent HD,45 cases).The prognosis of 60 d was followed up,including 60-day all-cause mortality,in-hospital all-cause mortality and recovery of kidney function.Results There were no statistical differences in basic clinical characteristics between 2 groups (P ＞ 0.05).The results of 60-day' follow-up showed,the mortality in HF group was 68.0％ (34/50),and in HD group was 82.2％ (37/45).There was statistical difference (risk ratio 0.75,95％ CI 0.80-1.28,P =0.036).There were no statistical differences in the in-hospital mortality and recovery rate of kidney function (P ＞ 0.05).There was no statistical difference in complication rate between 2 groups (P＞ 0.05).Conclusion The mortality is significantly lower in critically ill patients with AKI treated with intermittent high-volume predilution on-line HF,compared those treated with standard intermittent HD.

Objective To compare the effect of two different dialysis modalities, hemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD) on insulin resistance in patients with adult end-stage renal disease (ESRD), and to identify the possible predictive factors for insulin resistance. Methods Fifteen non-diabetic patients with ESRD (ESRD group) were selected. Eight patients were treated with HD (HD group), and 7 patients were treated with CAPD (CAPD group). The insulin inhibition was examined by hyper insulin-euglycemic glucose clamp technique before and after dialysis treatment, and the glucose disposal rate (GDR) was used as an index of insulin sensitivity during the clamp technique. Meanwhile, 8 healthy controls were selected as control group. The biochemical parameters which might be associated with insulin resistance were determined by multiple linear regression. Results The GDR in control group was (9.93 ± 1.33) mg/(kg · min), in ESRD group was (6.44 ± 1.76) mg/(kg·min), and there was statistical difference (P<0.05). The GDR in HD group after treatment was increased from (6.53 ± 1.84) mg/(kg · min) to (9.74 ± 2.88) mg/(kg · min), and there was statistical difference (P<0.01). The GDR in CAPD group after treatment was increased from (6.35 ± 1.65) mg/(kg·min) to (8.18 ± 1.76) mg/(kg·min), and there was statistical difference (P<0.05). Multiple linear regression result showed that the levels of urea nitrogen, hematocrit and bicarbonate were significant predictive factors in insulin resistance (P<0.05). Conclusions CAPD and HD therapy can improve insulin resistance in adult patients with ESRD.
