[Abstract ] Objective Ubiquitin carboxyl hydrolase L1(UCH-L1) is a neuron cytoplasm protein and increased UCH-L1 lev-el in cerebrospinal fluid( CSF) indicates brain injury.The study aimed to indentify UCH-L1 level in CSF of patients with subarachnoid hemorrhage(SAH) and assess the prognosis value of UCH-L1. Methods Retrospective analysis was made on 40 aneurismal SAH patients hospitalized in our department from August 2014 to February 2015.In the experiment group, CSF was taken by lumbar punc-ture in day1-day3, day5-day7, and day8-day10 after subarachnoid hemorrhage.In the control group, a single CSF sample was collect-ed during spinal anesthesia before surgery in 10 patients without neurologic disease.ELISA was applied to determine the concentration of UCH-L1 in CSF followed by comparison.Analysis was also made on relationship of the changes of UCH-L1 and modified rankins scale( MRS) 6 months later. Results CSF UCH-L1 concentrations in all SAH patients were significantly increased in day1-day3 ( P<0.05) after SAH, peaked in day5-day7 (P<0.01) and elevated un-til days 8-10 ( P<0.01 ) .MRS at 6 months showed a significant correlation with CSF levels of UCH-L1 in day5-day7 ( correlation co-efficient CC=0.691, P=0.001) and day8-day10 (CC=0.583,P=0.03), but not in days1-day3 (CC=0.364,P=0.08).SAH pa-tients with a good outcome at 6 months ( MRS<4) had much lower UCH-L1 levels in day5-day7 ( P=0.001) and day8-day10 ( P=0.041) than those with a poor outcome (MRS≥4).Higher UCH-L1 level at day5-day7 was a predictive marker of poor outcome in bi-nary logistic regression analysis (P=0.003); Conclusion The study suggests that increased CSF UCH-L1 level in day5-day7 after SAH is correlated with higher MRS and predicts an adverse clinical outcome 6 months after SAH.

Cerebral vasospasm(CVS) is a common complication following aneurysmal subarachnoid hemorrhage(SAH),and is the leading cause of death and disability in SAH patients.Till now,although there is no special treatmemt for CVS,the clinical intervention of CVS has gotten a rapid progress with the development of basic research in recent years.The clinical advancement of CVS management is reviewed.

Using proliferating inhibition test, the effects of three cultivars of black mushroom on the growth of gastric carcinoma cell in vitro were observed. We have found that the extracts of all three cultivars of black mushroom had inhibiting effects on the growth of tumor cells in medium at some levels, especially Cr-02 was the most evident one.The results suggest that black mushroom has some anti-tumor effects, and it is worthwhile to study farther for verification.

Methods Primary glomerulonephritis patients receiving GC therapy were observed and bone mineral density (BMD) in the lumbar spine and the femoral neck were measured. Age, sex, body - mass - index, smoking history, the time and accumulative dose of GC treatment, and the state of osteoporosis prevention were investigated, the factors that influence the BMD were analyzed. Results A total of one hundred and twenty- three patients were included in this study. Among them, osteoporosis and os-teopenia were found in 82 patients (66.7%). Lumbar spine BMD decrease gradually with the increase of the accumulative dose of GC. There were statistical differences in the BMD of lumbar spine in patients with receving GC at the period of less than 1 month compared with other groups( 1-12 months) (P

AIM:To observe the effect of rosiglitazone (RGZ) pretreatment on the expression of peroxisome proliferator-activated receptor γ( PPARγ) , nuclear factor E2-related factor 2 ( Nrf2 ) and heme oxygenase-1 ( HO-1 ) in the microglia cells activated by thrombin.METHODS:Microglia cells were obtained from the brain tissues of the newborn rats and were primarily cultured in vitro.After cultured for 14 d, the microglia cells were used in the experiment.The iso-lated microglia cells were randomly divided into normal control group, thrombin stimulation group ( TH group) , rosiglita-zone intervention group ( RGZ +TH group ) and retinoic acid intervention group ( RA +TH group ) .The expression of PPARγ, Nrf2 and HO-1 was observed by immunocytochemistry, real-time PCR and Western blot.RESULTS:The number of positive staining cells of PPARγ, Nrf2 and HO-1 in TH group, RGZ+TH group and RA+TH group were increased re-markably as compared with control group.The significant increases in PPARγ, Nrf2 and HO-1 were observed in RGZ+TH group compared with other groups.The mRNA expression of PPARγ, Nrf2 and HO-1 in RGZ+TH group was increased significantly as compared with TH group, control group or RA+TH group (P<0.01), Besides, the mRNA expression of Nrf2 and HO-1 in RA+TH group was decreased as compared with TH group or RGZ+TH group (P<0.01).The protein levels of PPARγ, Nrf2 and HO-1 in RGZ+TH group were significantly increased as compared with TH group, control group or RA+TH group (P<0.01).The protein expression of Nrf2 and HO-1 in RA+TH group was decreased as com-pared with TH group or RGZ+TH group (P<0.01).CONCLUSION:Rosiglitazone pretreatment might increase the ex-pression of PPARγ, Nrf2 and HO-1 in the microglia cells activated by thrombin.By inhibiting the expression of Nrf2 after RA pretreatment, the expression of the downstream gene HO-1 is also influenced.The anti-oxidative stress effects of rosigli-tazone might be achieved partly by modulating Nrf2 to control the downstream gene HO-1.

Objective To activate the microglia cells by using thrombin,and then to observe the effect of precondition of rosiglitazone (RGZ)-pretreated on the expression change of peroxisome proliferator-activated receptor-γ (PPARγ),nicotinamide adenine dinucleotide phosphate:quinone oxidoreductase (NQO1) and γ-glutamylcysteine synthetase (γ-GCS).Methods Microglia cells were obtained from the brain tissues of the newborn rats and were primary cultured in vitro.The microglia cells were isolated in 14 days.The isolated microglia cells were randomly devided into normal control group (control group),thrombin stimulation group (stimulation group) and rosiglitazone intervention group (RGZ + TH group).The PPARγ,NQO1 and γ-GCS were observed by immunocytochemistry and real-time polymerase chain reaction (RT-PCR) methods.Results The immunocytochemistry showed that the number of stained cells of PPARγ,NQO1 and γ-GCS in stimulation group and RGZ + TH group were increased remarkably as compared with the control group.A significant increase of the PPARγ,NQO1 and γ-GCS was observed in the RGZ + TH group compared to the others.The RT-PCR method demonstrated that the expressions of PPARγ mRNA(211.88 ± 58.75),NQO1 mRNA(182.67 ± 62.09) and γ-GCS mRNA (188.17 ± 57.06) in RGZ + TH group were increased significantly as compared with the stimulation group (119.19 ± 44.58,101.73±32.19,108.81 ±19.71) or the control group (0.34±0.21,0.73±0.46,0.30±0.13;F=181.50,286.63,614.43,all P ＜ 0.01).Conclusion Medium-dose rosiglitazone-pretreated might increase the expression of PPARγ,NQO1 and γ-GCS in microglia cells activated by thrombin.Rosiglitazone might activate the PPARγso that increase its downstream gene to achieve its anti-oxidative stress effects.

ObjectiveTo investigate the effect of dexmedetomidine on the median effectivetarget effectsite concentration (EC50) of remifentanil required for preventing body movement in response to skin incision made under propofol sedation.MethodsForty ASA Ⅰ or Ⅱ patients aged 20-50 yr weighing 45-58 kg scheduled for elective breast tumor excision were randomly allocated into 2 groups ( n =20 each):group remifentanil (group R) and group remifentanil + demedetomidine ( group RD).Sedation was induced with propofol TCI at target plasma concentration of 3.0 mg/L in both groups.In group RD dexmedetomidine 1.0 μg/kg was infused iv over 10 min before start of propofol TCI,while in group R equal volume of normal saline was infused instead of dexmedetomidine.Remifentanil TCI was started with target effect-site concentration set at 3.0 and 2.5 μg/L in groups R and RD respective at 13 min after beginning of propofol TCI.Skin incision (3 cm in length) was made when the target concentrations of propofol and remifentanil TCI were reached.Body movement was assessed by a nurse not involved in this study.EC50 and 95％ confidence interval (CI) of remifentanil were determined by up-and-down technique.The target effect-site concentration was increased or decreased by 20％ depending on the response of the previous patient to skin-incision.ResultsThe EC50 of remifentanil for preventing body movement in response to skin incision performed under propofol sedation was 1.7 μg/L (95％ CI 1.5-1.9 μg/L) and 2.5 μg/L (95％ CI 2.2-2.7μg/L) in groups RD and R respectively.The EC50 of remifentanil was significantly lower in group RD than in group R.ConclusionDexmedetomidine 1.0 μg/kg can decrease EC50 of remifentanil for preventing body movement in response to skin incision made under propofol sedation.
