Objective To observe the therapeutic effects of stellate ganglion block (SGB) with oxycodone and acetaminophen tablets on the treatment of migraine. Methods 100 patients with migraine were divided into two groups randomly. They received SGB with oxycodone and acetaminophen tablets (experimental group) or only SGB (control group) respectively. The parameters included pain intensity before and 1 d,3 d,1 w,1 m and 3 m after the treatment, and pain relief rate of each patient. The adverse effects were also evaluated. Results The pain intensity described as numeric rating score (NRS) decreased in the two groups at each time point. In the experimental group, the value of NRS was significantly less than that in the control group at 3d,1m and 3m after the treatment. The effec-tive rate ha the experimental group and the control group were 88% and 68%. Conclusion SGB with oxycodone and acetaminophen tablets is more effective for migraine and deserves widely used in patients.

Objective To improve EP9-A2 for Bias estimation among multiple quantitative detection systems within full range of AMR.Methods 40 patients specimens were determined twice for serum total cholesterol by four detection systems(A,B,C and D).With system A served as comparative method,Bias between A and the other three was evaluated according to CLSI EP9-A2 separately.Furthermore,DD(distance from deviation to tolerable error)and its average confidence intervals between every two sys-tem were calculated and compared with zero.The confidence interval of greater than zero was served as criteria for accepting bias between every two system.Results Bias between A and the other three meet the analytical quality specification according to EP9-A2,although that of D system was positive,and those of B and C system were negative.DD between every two system obeyed nor-mality distribution.All biases between every two system wes acceptable except that between B and D,causing of their interval con-taining zero.After correcting of results from system D,Biases between every two system were all acceptable.Plots of confidence in-terval could provide a full range bias assessment within AMR.Conclusion Comparability and Bias estimation in full range of AMR for results between every two system among 3 or more systems could be evaluated by confidence intervals.

AIM: To explore the pathogenesis of aplastic anemia (AA), we identified the crucial isoform of cyclin D that determine the proliferation of the cord blood CD34~+ cells and observed effects of AA serum on the expression of crucial cyclin D isoform in umbilical cord blood CD34~+ cells. METHODS: The CD34~+ cells were isolated with MIDI-MACS system. The isoforms of cyclin D were detected by RT-PCR and Western blotting. Methylcellulose culture system was used to measure the formation of CFU-GM. The expression level of crucial cyclin D isoform was assayed by RT-PCR and Western blotting after the CD34~+ cells were incubated in AA serum. RESULTS: The crucial cyclin D isoform in CD34~+ cells was cyclin D3. The AA serum inhibited the formation of CFU-GM and down-regulated expression level of the cyclin D3 from the mRNA to protein level, respectively. CONCLUSION: The AA serum inhibits the proliferation of CD34~+ cells and down-regulates level of cyclin D3, this may be one of hematopoiesis inhibition mechanisms in AA.

BACKGROUNDThe optimal ventilated status under total intravenous or inhalation anesthesia in neurosurgical patients with a supratentorial tumor has not been ascertained. The purpose of this study was to intraoperatively compare the effects of moderate hyperventilation on the jugular bulb oxygen saturation (SjO 2 ), cerebral oxygen extraction ratio (O 2 ER), mean arterial blood pressure (MAP), and heart rate (HR) in patients with a supratentorial tumor under different anesthetic regimens.

METHODSTwenty adult patients suffered from supratentorial tumors were randomly assigned to receive a propofol infusion followed by isoflurane anesthesia after a 30-min stabilization period or isoflurane followed by propofol. The patients were randomized to one of the following two treatment sequences: hyperventilation followed by normoventilation or normoventilation followed by hyperventilation during isoflurane or propofol anesthesia, respectively. The ventilation and end-tidal CO 2 tension were maintained at a constant level for 20 min. Radial arterial and jugular bulb catheters were inserted for the blood gas sampling. At the end of each study period, we measured the change in the arterial and jugular bulb blood gases.

RESULTSThe mean value of the jugular bulb oxygen saturation (SjO 2 ) significantly decreased, and the oxygen extraction ratio (O 2 ER) significantly increased under isoflurane or propofol anesthesia during hyperventilation compared with those during normoventilation (SjO 2 : t = -2.728, P = 0.011 or t = -3.504, P = 0.001; O 2 ER: t = 2.484, P = 0.020 or t = 2.892, P = 0.009). The SjO 2 significantly decreased, and the O 2 ER significantly increased under propofol anesthesia compared with those values under isoflurane anesthesia during moderate hyperventilation (SjO 2 : t = -2.769, P = 0.012; O 2 ER: t = 2.719, P = 0.013). In the study, no significant changes in the SjO 2 and the O 2 ER were observed under propofol compared with those values under isoflurane during normoventilation.

CONCLUSIONSOur results suggest that the optimal ventilated status under propofol or isoflurane anesthesia in neurosurgical patients varies. Hyperventilation under propofol anesthesia should be cautiously performed in neurosurgery to maintain an improved balance between the cerebral oxygen supply and demand.

OBJECTIVETo demonstrate the vasodilatation activity of the coumarin-containing Angelica dahurica var. formosana and to further analyze active components in the herb extracts.

METHODS(1) The vasodilatation effects induced by different extracts (cyclohexane, ethyl acetate, acetone, methanol, 95 % ethanol and water) of Angelica dahurica var. formosana on mouse thoracic aorta pre-contracted with phenylephrine were investigated. (2) The amount of imperatorin and isoimperatorin in each extract was measured by high-performance liquid chromatography. (3) The vasodilatation effects of imperatorin and isoimperatorin on mouse thoracic aorta were compared using the same in vitro method. (4) The vasodilatation mechanism of imperatorin in the mouse thoracic aorta pre-contracted with phenylephrine was studied using the methods of denuded endothelium, NG-nitro-L-arginine methylester (L-NAME, a nitric oxide synthase inhibitor), and propranolol.

RESULTS(1) The cyclohexane and ethyl acetate extracts of Angelica dahurica var. formosana decreased the maximal response of phenylephrine-induced mouse thoracic aorta contraction dose-dependently, with 50% inhibiting concentration (IC(50)) values of 35.3+/-12.4 mg/L and 40.5+/-12.0 mg/L, respectively. The vasodilatation effect of imperatorin and isoimperatorin was dose-dependent. (2) The cyclohexane extract, showing the strongest vasodilatation effect, possessed the highest contents of imperatorin (4.09%) and isoimperatorin (0.27%, w/w). There was a correlation between the vasodilatation activity and the contents of imperatorin and isoimperatorin in the extracts. (3) The vasodilatation effect of imperatorin was about 4-fold stronger than that of isoimperatorin. (4) The vasodilatation effect of imperatorin was signifificantly attenuated to 24.88%+/-4.06% in the denuded endothelium group compared with the intact endothelium group. And 1 mmol/L L-NAME reduced the imperatorin-induced vasorelaxation by 32.18 %+/-11.29 %.

CONCLUSIONSThe principal effective component of Angelica dahurica var. Formosana was found to be imperatorin. Imperatorin-induced vasodilatation is at least partially regulated by nitric oxide, and has no correlation to beta-receptor.
