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.

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.

Objective To observe blood gas analysis of internal carotid artery and internal jugular vein to calculate the cerebral extraction of oxygen, and to investigate the relationship between oxyhemoglobin in internal jugular vein, cerebral extraction of oxygen, and the prognosis of patients with head injury. Method Seventy patients with acute severe head injury in ICU of Taizhou People Hospital were studied, and another 80 patients with mild head injury were enrolled as controls. Twenty-four hours after first aid such as keeping airway open and circulatory and ventilation support, and emergency craniotomy, the blood samples from internal carotid artery and internal jugular vein were collected for blood gas analysis including SaO2, PaO2, SjvO2, PJVO2 > PaCO2, PJVCO2, SaO2-SjvO2, Pa-jvCCO2, CaO2-CjvO2 and Ca-jvO2/CaCO2 (CEO2, cerebral oxygen extraction). Results There were significant differences in SjvO2, PjvO2, Sa-jvO2, Pa-jvO2 Ca-jvO2 and CEO2 between two groups. Conclusions The SjvO2 and CEO2 represent the cerebral oxygen uptake and oxygen consumption precisely, and they can be used to predict the outcome of patients with severe craniocerebral trauma commendabiy.

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.

Objective To investigate the changes and the clinical significance of serum concentration of soluble Fas (sFas) and Fas ligand (FasL) in the elderly. Methods Fifty elderly subjects and forty-seven adults were recruited. Serum concentration of sFas and EasL were detected by enzyme-linked immunosorbent assay (ELISA) . Psychosocial stress and coping styles were also evaluated. Results The sFas level of the elderly was significantly higher than that in control group,whereas the EasL level was decreased with ageing (P<0.01). A positive correlation between sFas level and psychosocial stress, and a negative correlation between sFas level and positive coping were also found (all P<0. 05). Conclusions Age-related changes occur in serum sEas and EasL levels.The interaction of sFas/FasL system with psychosocial stress and coping styles seems to play important roles in immunosenescence. Our results also suggest that during aging a subtle balance between sFas and FasL could exist.

Objective: To compare the efifcacy between emergent and delayed stent implantation in patients with ST-elevation myocardial infarction (STEMI) after thrombus extraction.
Methods: A total of 82 STEMI patients who received thrombus extraction and intracoronary injection of tiroifban, sodium nitroprusside, nitroglycerin via thrombus extraction catheter and with recovered TIMI 3 lfow from 2012-11 to 2014-01 were retrospectively studied. The patients were randomized into 2 groups by SAS software: Emergent group, the patients received stent implantation immediately upon diagnosis and Delayed group, the patients were treated by anti-platelet and anticoagulant medication for 10-14 days, and then received stent implantation. n=41 in each group. The primary and secondary indicators were compared between 2 groups which including ST-segment resolution (STR), the occurrence rate of no-relfow/slow-relfow, myocardial blush grade (MBG) 3, parameters of stent, ventricular remodeling condition, the incidence of major adverse cardiac events (MACE).
Results: ①Delayed group had the post PCI STR at (68.2 ± 9.2)%, TIMI 3 grade at 97.5%, MBG 3 at 69.0%and corrected TIMI frame count (CTFC) at (19.5 ± 5.2), compared with Emergent group, P<0.05. The occurrence rate of no-relfow/slow-relfow in Delayed group and Emergent group were 2.5% and 31.0%, P<0.01. ②The parameters of stents in Delayed group and Emergent group were as the number at (1.21 ± 0.32) vs. (1.76 ± 0.76), the mean length at (28.3 ± 11.7) mm vs. (33.7 ± 12.9) mm, the mean diameter at (3.17 ± 0.76) mm vs. (2.82 ± 0.87) mm, all P<0.01. Delayed group had the higher dilating pressure than that in Emergent group, (18.5 ± 6.2) atm vs (13.6 ± 7.1) atm, P<0.01, and more patients in Delayed group receive high-pressure non-compliant balloon dilation 75% vs 23.8%, P<0.01. ③With 6 months of follow-up study, there were slightly declining trend for LVEF and LVSF in both groups than that at 1 week condition, P>0.05, while LVEDV and LVEDD increased than 1 week, P<0.05, the changes were more obvious in Emergent group, P<0.05. Delayed group had less MACE occurrence, P<0.05.
Conclusion: Delayed stent implantation in STEMI patients after thrombus extraction had reduced incidence of post PCI no-relfow/slow-relfow phenomenon, improved myocardial reperfusion and less MACE occurrence.
