Objective To evaluate the efficacy of ultrasound?guided transversus abdominis plane ( TAP) block with different concentrations of ropivacaine for analgesia after cesarean section. Methods A total of 120 parturients, aged 24-31 yr, of American Society of Anesthesiologists physical statusⅠ or Ⅱ, weighing 64-73 kg, at 35 to 41 week gestation, scheduled for elective cesarean section, were randomly di?vided into 3 groups ( n= 40 each) using a random number table: 0?25% ropivacaine group ( group Ⅰ) , 0?20% ropivacaine group ( groupⅡ) , and 0?15% ropivacaine group ( groupⅢ) . A patient?controlled an?algesia pump was connected at the end of surgery, and the corresponding concentration of ropivacaine 1?5 mg∕kg was injected into the bilateral TAP under the guidance of ultrasound in each group. Visual analogue scale score was maintained ≤3. The number of attempt and the number of patients requiring rescue analge?sic were recorded at 48 h after surgery. The occurrence of TAP block?related complications was observed and recorded. Results Compared with groupⅢ, the number of attempt and the number of patients requi?ring rescue analgesic were significantly decreased in Ⅰ and Ⅱ groups ( P<0?05 ) . Compared with groupⅡ, the number of attempt and the number of patients requiring rescue analgesic were significantly de?creased in group Ⅰ (P<0?05). No TAP block?related complications were detected in the three groups. Conclusion Ultrasound?guided TAP block with 0?25% ropivacaine is helpful in improving the analgesic efficacy after cesarean section without serious complications.

Objective To investigate the protective effect of indole-3-carbinol (I3C) on radiation-induced mouse bone marrow hematopoietic cell injury and the involved mechanisms. Methods (1) The bone marrow nuclear cells (BMNCs) from CD45.1 subtype of C57BL/6J mice were collected by a density gradient centrifugation method. The BMNCs were pretreated with a series doses of I3C (0 mol/L, 10-8 mol/L-10-3 mol/L) and then exposed with radiation of 137Csγ-ray (doses of irradiation were 0 Gy, 1 Gy and 4 Gy). After 18-hour culturing, the bioluminescence method was used to detect the cell viability. (2) These cells were divided into control group and 10-6 mol/L I3C group. Both groups were received the irradiation (0 Gy, 1 Gy and 4 Gy) and inoculated into the methylcellulose semi-solid culture medium to incubate 7 days, the colony forming unit-granulocyte monocytes (CFU-GM) were observed. (3) Twenty-four CD45.2 subtype mice used as the receptor were exposed with 8 Gy radiation. The CD45.1 BMNCs were divided into control group, 4 Gy irradiation group, 4 Gy irradiation and 10-6 mol/L I3C group. Donor cells were harvested from C57BL/6J (CD45.1) mice after they received various treatments, and were then mixed with competitive BMNCs from C57BL/6J (CD45.2) mice. The mixed cells were transplanted into recipient mice (8 mice/group). Flow cytometry was used to analyze the proportion of donor cells in peripheral blood of receptor. (4) The cells were divided into control group, 10-6 mol/L I3C group, 1 Gy irradiation group, 1 Gy irradiation with 10-6 mol/L I3C group. After 24-hour culturing, Western blot assay was used to detect the expression levels of nuclear factor erythroid 2-related factor 2 (Nrf2) and hemeoxygenase-1 (HO-1). Results (1) I3C showed a significant cytotoxic effect on the BMNCs when its concentration was above 10-4 mol/L. 10-7-10-6 mol/L I3C could reduce the radiation injury of BMNCs under the same dose of irradiation. Therefore, 10-6 mol/L I3C was chosen for subsequent experiments. (2) The CFU-GM was significantly higher in 10-6 mol/L I3C group than that of control group (P<0.05). (3) Results of flow cytometry showed that the proportion of donor cells in receptor was significantly higher in 4 Gy irradiation group than that of control group, which decreased the engraftment capability of irradiated HSCs (P<0.05), although the engraftment capability of irradiated HSCs improved after 10-6 mol/L I3C treatment. (4) I3C significantly enhanced the increased protein expression of Nrf2 and HO-1 caused by radiation (P<0.05). Conclusion I3C has a protective effect on hematopoietic cells following radiation-induced injury, which may be related with activating the Nrf2/HO-1 signal pathway.

Objective To investigate the effect of music electroacupuncture on perifocal ferric ions and neuronal apoptosis and the brain water content in rats with acute cerebral hemorrhage and explore the mechanism of its action on acute cerebral hemorrhage.Methods One hundred and twenty-eight healthy adult male Wister rats were randomized to normal, model, electroacupuncture and music electroacupuncture groups. In each group, four time points of 6 hrs, 24 hrs, 3 days and 7 days were set up, eight rats each time point. A rat model of acute cerebral hemorrhage was made using collagenase. In the electroacupuncture and music electroacupuncture groups, point Baihui was connected to the anode and point Taiyang to the cathode, 2 voltage was used as a selection parameter and electroacupuncture lasted 30 min. Intracerebral perifocal ferric ions and neuronal apoptosis and the brain water content were measured at four time points of 6 hrs, 24 hrs, 3 days and 7 days after model making.Results Intracerebral ferric ion content was higher in the model, electroacupuncture and music electroacupuncture groups of rats than in the normal group at 6 hrsafter model making (P<0.05), lower in the electroacupuncture and music electroacupuncture groups than in the model group at 24 hrs, 3 and 7 days after model making (P<0.05) and lower in the music electroacupuncture group than in the electroacupuncture group at 3 and 7 days after model making (P<0.05). Intracerebral neuronal apoptosis was higher in the model, electroacupuncture and music electroacupuncture groups of rats than in the normal group at 6 hrs after model making (P<0.05) and lower in the music electroacupuncture group than in the electro- acupuncture group at 7 days after model making (P<0.05). The brain water content was higher in the model, electro- cupuncture and music electroacupuncture groups of rats than in the normal group at 6 and 24 hrs after model making (P<0.05), lower in the electroacupuncture and music electroacupuncture groups than in the model group at 3 days after model making (P<0.05) and lower in the music electroacupuncture group than in the electroacupuncture group at 7 days after model making (P<0.05).Conclusions Music electroacupuncture has a benign regulating effect on intracerebral perifocal ferric ions, inhibits neuronal apoptosis around hematoma in the early stage and reduces cerebral edema in rats with acute cerebral hemorrhage. Its therapeutic effect is superior to that of electroacupuncture.

Objective To evaluate the clinical value of pre-operative double embolization for nasopharyngeal angiofibroma. Methods Digital subtraction angiography(DSA) was carried out in 7 cases of nasopharyngeal angiofibroma. In six cases,the supplying arteries originated from the maxillary artery and the branches arising from internal carotid artery underwent double embolization-direct percutaneous puncture embolization and selective embolization of blood supplying arteries. In another case,the supplying artery originated from maxillary artery was only undertaken selective embolization for the feeding arteries. Results All the tumor masses reduced in vonlume obviously or even disappeared on the angiography after embolization. Conclusions Pre-operative double embolization for nasopharyngeal angiofibroma could be a necessary additional treatment method. (J Intervent Radiol,2006,15: 342-344)

Objective To evaluate the effects of different doses of epidural capsaicin on pain threshold, neurological function and spinal neurons.Methods Thirty-six male New Zealand white rabbits weighing 2.5-3.0 kg were randomly divided into 4 groups (n = 9 each): control group and 3 capsaicin groups (Cap 1, 2, 3). The animals were anesthetized with 10% chloral hydrate 50-75 mg?kg-1 i.v. . An intrathecal catheter was inserted at L6,7 interspace and correct placement was confirmed by outflow of CSF. 1 ml of 0.1 % ( Cap1) , 0.25 % ( Cap2 ) or 0.5% (Cap3 ) capsaicin was injected intrathecally 24 h after IT catheter was placed. Threshold to noxious thermal stimuli was measured and gait of the hind limbs were assessed using Johnson score (5 = normal, 0 = completely paralyzed), before and 1, 3, 7, 10, 15, 20, 25, 30 days after IT injection. On the 2nd day after IT injection 3 animals were killed in each group and the lumbar segment of spinal cord (L6,7) was immediately removed for light and electron microscopic examination. Results The threshold to noxious thermal stimuli was significantly higher in the 3 capsaicin groups than in control group ( P
