Objective:To study the effect of Vitamin E(VitE)and Sodium selenite on nonalcoholic fatty liver(NAFL).Methods:24 SD rats were randomly divided into 3 groups.The model group,treatment group and contrast group were respectively fed with high fat diet,interfering diet and normal diet.All animals were sacrificed at the end of the 5th week.The liver pathology was observed under the light microscope.Superoxide dismutase(SOD),malondialdehyde(MDA)were determined by biochemistry analysis.The expressions of nuclear factor kappa B(NF-kB)and tumor necrosis factor alpha(TNF-?)proteins in hepatocytes were examined by immunohistochemistry.Result:①compared with the contrast group,serum and liver SOD levels decreased in model group,while MDA were raised.The expressions of NF-kB and TNF-a proteins in liver tissue increased significantly in model group.②compared with the model group,serum and liver SOD level increased in treatment group,while MDA was lowered.The expression of NF-kB proteins in liver tissue was reduced in treatment group,and no significant changes occured in TNF-a protein expression.Conclusions:Combination of sufficient quantum of VitE and Sodium selenite can improve the SOD activities and reduce the expression of NF-kB proteins in liver tissue,which is possibly the important mechanism for VitE and Sodium selenite to prevent NAFL.

BACKGROUND: Traumatic brain injury generates a cascade of arachidonic acid metabolic events that mainly presented by the increment of prostaglandin and oxygen free radicals. Indomethacin can potently inhibit the activity of cyclooxygenase, decrease the synthesis of prostaglandins, and may decrease the production of oxygen free radical, and thus may attenuate the pathological changes of brain injury.OBJECTIVE: To observe the changes of prostaglandin in early brain injury and after indomethacin intervention, so as to explore the pharmacological mechanism of indomethacin.DESIGN: A randomized and controlled trial based on experimental animals.SETTING: Department of neurosurgery and department of cerebral surgery in a university hospital.MATERIALS: This study was carried out at the Laboratory of Neurosurgery Department, Medical College of Southeast University between March and September 2000. Thirty-six hybrid cats were randomly divided into normal control group, brain injury group and indometbacin intervention group, with 12 cats in each group.INTERVENTIONS: Brain injury was simulated according to previously reported grading mechanical traumatic animal model establishment; cats with medium brain injury were enrolled in this study. The ultimate concentrations of prostacyclin (PGI2) and thromboxane A (TXA2) to 6-keto-prostaglandin F 1 alpha(6-keto-PGF1α) and thromboxane B2(TXB2) in brain vein blood, as well as total brain superoxide dismutase(SOD) and cerebral water content were measured 6 hours after trauma.MAIN OUTCOME MEASURES: 6-keto-PGF1α, TXB2, SOD, and cerebral water content.RESULTS: Both 6-keto-PGF1α and TXB2 in brain vein blood remarkably increased in early brain injury[from(0.057±0.010) g/L to (0.264±0. 126) g/L, from(0. 060 ±0. 012) g/L to(0. 134 ±0. 048) g/L respectively], with the increment of the former higher than the latter, the ratio of TXB2/6-keto-PGF1α decreased from 1. 052 ±0. 145 to 0. 545 ±0. 184, and cerebral water content increased from(77.39 ± 0. 36)% to (78.06±0.41)% ; meanwhile, total brain SOD significantly decreased from (94. 869 ± 5. 418) μkat/g to(54. 368 ± 3. 417) μ kat/g( P ＜ 0.01) . In contrast to brain injury group, the concentrations of 6-keto-PGF1α and TXB2 in indomethacin intervention group significantly decreased, which were similar to those of control group, but the total SOD significantly increased from (54. 368 ±3. 417) pkat/g to (81. 433 ±7. 268) μkat/g (P ＜0. 01), and water content lightly decreased without statistical significance( P ＞ 0. 1 ).CONCLUSION: PGI2 and TXA2 increase in early brain injury in experimental cat model, accompanied by free radical synthesis, resulting in the exacerbation of brain injury. Indomethacin may be helpful to relieve posttraumatic secondary brain injury by regulating the imbalance of PGT2 / TXA2 and decreasing the production of free radical.

Objective To establish the scoring system for early prediction of multiple organ dysfunction syndrome (MODSE) induced by pulmonary infection in the elderly. Methods A total of 393 inpatients with pulmonary infection, aged 60 years and over, were enrolled in this study and the data of them from January 2001 to December 2006 were analyzed retrospectively. All patients were divided into MODSE group and non-MODSE group. The effects of age, chronic disease and blood test items of healthy examination on the pathogenesis of MODSE were explored. The early prediction indexes which were selected from age, 21 chronic diseases and 15 blood test items of healthy examination were scored to establish the scoring system for early predicting MODSE. Results The age, chronic obstructive pulmonary disease, chronic respiratory failure, pulmonary fibrosis, chronic cardiac insufficiency, cerebrovascular disease, diabetes, chronic renal failure, hemoglobin, albumin,urea nitrogen and fasting blood glucose were selected to establish the scoring system for early predicting MODSE. Conclusions The scoreing system for early predicting MODSE may be used to screen the high risk population of MODSE induced by pulmonary infection, which is valuable in early prediction of MODSE.

OBJECTIVE:To observe therapeutic efficacy and safety of Leonurus artemisia injection combined with carboprost tromethamine for preventing postpartum hemorrhage (PPH) of pregnant women after cesarean section. METHODS:177 pregnant women undergoing cesarean section were randomly divided into control group(87 cases)and observation group(90 cases). Preg-nant women of both groups received cesarean section. Control group was given intramuscular injection of oxytocin 20 U in uterine muscle wall above the incision after the foetus parturition,and given intravenous dripping of oxytocin 20 U added into 0.9% sodi-um chloride 250 mL;4 h after the operation,the pregnant women received intramuscular injection of oxytocin 10 U,every 12 hours,for 3 days. Observation group was given intramuscular injection of L. artemisia injection 2 mL and Carboprost tromethamine injection 1 mL in uterine incision after the foetus parturition;4 h after the operation,the pregnant women received intramuscular in-jection of L. artemisia injection 2 mL and Carboprost tromethamine injection 1 mL,and then give L. artemisia injectien 2 mL,ev-ery 12 hours,for 3 days. Clinical efficacies of 2 groups were observed as well as blood loss during operation,2 h after operation and 24 h after operation,the amount of hemoglobin(Hb)before operation and 24 h after operation,height of uterine fundus 3,7 d after operation,the occurrence of ADR. RESULTS:The total response rate of observation group was significantly higher than that of control group;blood loss during operation,2 h after operation and 24 h after operation,height of uterine fundus 3,7 d af-ter operation were also significantly than control group,with statistical significance(P<0.05). There was no statistical significance in Hb of pregnant women between 2 groups before operation(P>0.05). 24 h after operation,Hb of pregnant women in control group was significantly lower than before operation and observation group,with statistical significance(P<0.05);there was no sta-tistical significance in Hb of observation group between before operation and 24 h after operation(P>0.05). There was no statisti-cal significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:L. artemisia injection combined with car-boprost tromethamine shows significant therapeutic efficacy for PPH of pregnant women underwent cesarean section,can signifi-cantly reduce intraoperative and postoperative blood loss,accelerates the recovery of uterus without increasing the rate of ADR.

Aging or senescence is a process in which individuals undergo an exponential decline in vitality, leading to death. Recent years,much progress on the molecular mechanisms underlying senescence have been made. (1) Some senescence-related gene such as SEN6A,hic-5,din1 and MORF 4 have been clarified; (2) In 1997, through a set of experiments sponsered by scientists of Department of Biology Massachusetts Institute of Technology, it was found that the accommulation of extrachromosomal rDNA circles (ERC) in budding yeasts nucleolus is responsible for cell-senescence and the researchers propose that when enough of these circles accumulate, they clog the nucleus and prevent the cell from reading or replicating its genome, causing it to stop dividing and ultimately to die; (3) In another work finished by National Institute on Aging and the Geron biotech company of Melo, it was proved that a cells biological clock,which tells the cell how and how many times to divide, lies in its telomeres, little bits of DNA that coat the tips of the chromosome and it was clarified that a powerful enzyme,telomerase, with the potential to rejuvenate the human bodys aging tissues could effectively extend the shortened telomere . Although there is a long way to go, scientists still believe that it will be made reality in the future to greatly extend the life-span of human.
