This paper is to report the study of the metabolism of lidamycin in vitro including in plasma and microsomes to guide clinical therapy. Lidamycin was quantified by detecting its active ingredient using HPLC-MS/MS. The metabolic stability of lidamycin in rat, Beagle dog, monkey and human plasma and liver microsomes, and its inhibition to cytochrome P450 isoforms in human liver microsomes were studied. Results showed that lidamycin was metabolized in the four species of plasma, and the sequence of metabolic rates in plasma were in rat > in dog > in human > in monkey. But among the four species of liver microsomes, lidamycin was metabolized only in monkey liver microsomes. There was almost no inhibition to cytochrome P450 isoforms at the concentrations of between 0.0005 and 10 ng x mL(-1). Therefore, the property of lidamycin metabolism in human is similar with that in dog, and metabolism of other drugs would not be decreased by cytochrome P450 as used along with lidamycin in clinic.

This paper is to report the study of the metabolism of forscolin in plasma and liver microsomes for guiding clinical therapy. Forscolin was quantified by HPLC-MS/MS. The metabolic stability of forscolin in rat, Beagle dog, monkey and human plasma and liver microsomes, mediated enzymes of forscolin and its inhibition on cytochrome P450 isoforms in human liver microsomes were studied. Results showed that forscolin was not metabolized in plasma of the four species but metabolized in liver microsomes of the four species. The t1/2 of forscolin in rat, Beagle dog, monkey and human liver microsomes were (52.0 +/- 15.0), (51.2 +/- 5.9), (6.0 +/- 0.2) and (11.9 +/- 1.8) min; CL(int) were (75.6 +/- 18.7), (60.9 +/- 6.8), (513.8 +/- 14.3) and (176.2 +/- 25.6) mL x min(-1) x kg(-1); CL were (34.8 +/- 4.5), (23.3 +/- 1.0), (40.3 +/- 0.5) and (17.9 +/- 0.3) mL x min(-1) x kg(-1), respectively. Forscolin was metabolized by CYP3A4 in human liver microsomes. There was definite inhibition on CYP3A4 at the concentrations of forscolin between 0.1 ng x mL(-1) and 5 microg x mL(-1). Therefore, forscolin is rapidly excreted from liver microsomes. Attention should be paid to the drug interaction when forscolin was used along with other drugs metabolized by CYP3A4 in clinics.

Objective To investigate the prognostic effects of continuous renal replacement therapy on multiple organ dysfunction complicated with acute kidney injury.Methods Fifty nine patients who were diagnosed with multiple organ dysfunction syndrome (MODS) complicated with acute kidney injury (AKI) and underwent continuous renal replacement therapy (CRRT) were selected and grouped according to the Kidney Disease Improving Global Outcomes (KDIGO) staging.Their clinical data before CRRT were collected.The patients were grouped according to the Intensive Care Unit (ICU) prognosis,namely death and survival.The differences between two groups were analyzed.The multinomial logistic regression analysis was performed to explore the prognostic factors.Results With the increase of KDIGO stage,the Acute Physiology And Chronic Health Evaluation Ⅱ (APACHEII) score,Sequential Organ Failure Assessment (SOFA) score,the need for vasoactive drugs,and the number of cases with oliguria and ICU mortality rates showed an increasing trend,and those differences were statistically significant (P < 0.05).After multivariate analysis,KDIGO Ⅲ stage,the number of failed organs,oliguria,and the mean daily fluid balance were independent risk factors of death in patients who were diagnosed with MODS complicated with AKI and underwent CRRT.Conclusions The KDIGO classification plays an important role in predicting the prognosis of patients with MODS complicated with AKI in need of CRRT.The number of failed organs,oliguria,and the mean daily fluid balance are also the risk factors for prognosis.

Objective To detect the levels of high mobility group box 1 protein HMGB1),tumor necrosis factor-α (TNF-α),interleukin-6 (IL-6),C-reactive protein (CRP) in order to explore the clinical significance of HMGB1 in patients with severely traumatic brain injury.Methods A total of 75 patients composed of 40 male and 35 female with severely traumatic brain injury were hospitalized from March 2011 through March 2012.The scores of Glasgow Coma Scale (GCS) were 5-8 within 12 hours after brain injury.Casualties with history of hypertension,diabetes,severe diseases of heart,liver and kidney,and with concurrent trauma of other parts of body were excluded.Another 50 healthy subjects were enrolled as controls.Serum samples were taken from both patients and controls at admission.The levels of HMGB1,TNF-α and IL-6 were measured by using enzyme-linked immunosorbent assay (ELISA).The level of CRP was measured by using automatic biochemistry analyzer.Comparisons of the levels of HMGB1,TNF-α,IL-6and CRP between casuahies and healthy controls were carried out.The correlations of HMGB1 with TNF-α,IL-6,CRP in patients with severe traumatic brain injury were analyzed.Thereafter,75 patients were divided into two groups post hoc:the death group and the survival group.On the 1st day,the 3rd day and the 7th day after trauma,serum HMGB1 was detected.The comparison of HMGB1 was made between death group and survival group by using t-test.Results Serum HMGB1 level in the traumatic patients was higher than that of healthy controls (P < 0.01).Correlative analysis showed that there was a positive correlation between HMGB1 and TNF-α (r =0.365,P<0.05),IL-6 (r=0.530,P<0.05),CRP (r=0.661,P<0.05) in patients with severe traumatic brain injury.Serum HMGB1 level in the death group was higher than the survival group (P < 0.01).Conclusions Increased serum HMGB1 level was found after severe traumatic brain injury.There were positive correlations between HMGB1 and three inflammatory factors,TNF-α,IL-6and CRP.Serum HMGB1 should be used as reliable hiomarker to judge the prognosis of patients with severe traumatic brain injury.

AIM: To generate the angiopoietin-1 recombinant adenovirus for the further studies about adenoviral mediated angiopoietin-1 gene transfer in ischemic myocardium and its effect on the development of neoangiogenesis.METHODS: Angiopoietin-1-PAxCAwt cosmid DNA and adenoviral DNA-TPC were cotransfected to 293 cells by the use of calcium phosphate precipitation method. All recombinant adenoviruses were propagated and titrated in 293 cells, purified by cesium chloride density purification, dialyzed, and stored at-70 ℃. RESULTS: The result shows that the direction of the insert in the cosmid is correct and the replication-deficient angiopoietin-1 recombinant adenovirus was generated efficiently by COS/TPC homologous recombination, with the titers of 5.6?10 11 pfu/L. The viral stocks were demonstrated to be free of replication-competent wild type adenoviruses. The virus stocks in high titer were harvested in our experiment. CONCLUSION: The COS/TPC is an efficient method to prepare recombinant adenovirus and the angiopoietin-1 recombinant adenovirus could be further used in gene therapy.
