METHODS: 45 patients with essential hypertension undergoing general anesthesia were divided randomly into control (C, without depressor, n=15), urapidil (U, 0.5 mg?kg -1 , n=15), and nitroglycerine (N, 1 ?g?kg -1 , n=15) groups. The SBP, DBP, MAP, HR and RPP were measured during intubation and extubation and at the induction of anesthesia and the end of operation respectively. RESULTS: The SBP, DBP, MAP, HR and RPP increased markedly (P

Objective To investigate the changes in severe burn patients with acute renal failure by using continuous blood purification(CBP). Methods Twelve severe bum patients underwent early CBP were included in this study. The levels of creatinine、blood urea nitrogen and interleukin-6(IL-6) in plasma were determined. The termperature and heart were also observed. Results After the treatment of CBP,the clinical symptoms were improved obviously ( P ＜ 0. 05 ). The levels of creatinine[( 376. 2 ± 24. 5 ) μ mol/L vs ( 145.2 ± 57. 1 ) μmol/L] 、sodium concentration [( 5.3 ± 1.6 ) mmol/L vs ( 4. 0 ± 0. 7 ) mmol/L] and potassium concentration [( 153. 4 ± 13.0 ) mmol/L vs( 140. 1 ±8.6)mmol/L]in plasma were all decreased evidently after the treatment of CBP. There were significant differences ( t = 2. 79,3.06,3. 01, P ＜ 0. 05 ). The levels of IL-6 and APACHE Ⅱ score were ( 264. 31 ± 122.42 ) ng/Land( 15.2 ±5.8) scores before treatment. While after treatment,their levels were(94. 18 ±63. 82) ng/L and(5.4 ±3. 6) scores. The difference was also significant ( t = 4. 17,3. 67, P ＜ 0. 05 ). In this study, 8 patients cured and 4 patients died. Conclusion CBP could eliminate inflammation factors effectively in severe burn patients with acute renal failure. It could afford a useful assist treatment to these patients.

BACKGROUND:Forceful fixation and enough blood supply in fracture site are the fundament for treating bone nonunion. OBJECTIVE:To investigate the outcome of autologous lilac bone-grafting and plate fixation in treatment of the ununited distal ulnar fracture with osseous defects. DESIGN,TIME AND SETTING:The own control study was performed at the Department of Orthopaedics,Sixth People's Hospital,Shanghai Jiao Tong University from August 2002 to May 2006. PARTICIPANTS:Of 21 cases of the ununited distal ulnar fracture with osseous defects,13 cases were induced by ulnar and radial fracture,and 8 cases were induced by ulnar fracture. There were 15 cases of open fracture and 6 cases of closed fracture of first onset. Bone defects were 1.5 cm-5.0 cm,averagely 3.1 cm. METHODS:Bone defects were filled with intercalary lilac grafts. Length and axial ray of ulna were controlled. Ulna was fixed utilizing 5-8 wells 1/3 tubular plate,reconstruction plate or locking compression plate. At least two screws were used at the distal end,and 3 or 4 screws were fixed in the proximal end,FoUow-up was conducted once per month to observe clinical appearances and radiograph in each patient. MAIN OUTCOME MEASURES:Fracture nonunion,dorsal extension and palmer flexion of wrist joint,pronation and supination of the forearm were measured. RESULTS:All 21 cases were followed up for a mean time of 14.7 months. All the patients obtained bony union,and a mean time of 4.6 months (ranged 3 to 7 months). The distal ulnar healed with < 10° of angular deformity in a coronal plane in one patient and with 15° of angulation in a sagittal plane in another one,while others (19 patients) obtained satisfactory alignment. The excellent and good rate was 90.5％. CONCLUSION:Intercalary bone-grafting with autologous lilac and secure fixation for treating the ununited distal ulnar fracture with osseous defects can reconstruct ulnar length,correct deformities,and obtain good bone healing and functional recovery.

AIM: To observe the effects of hypertriglyceridemia and fenofibrate on CD40L expression in platelets in vitro and in vivo. METHODS: In vivo experiments, according to its own strict standards, 20 patients were respectively selected for hypertriglyceridemia group and control group, before and after treatment of fenofibrate for hypertriglyceridemia patients. The CD40 ligand positive rates of platelets by flow cytometry and plasma soluble CD40 ligand by ELISA were examined under the same conditions as control group. The CD40L and sCD40L in each group were compared. In in vitro experiments, all 6 objects plasma was chosen in the same condition except for triglyceridemia, after the co-incubation of these plasma with the same healthy platelets was performed and the interference with wy14643, the CD40 ligand positive rate of platelets by flow cytometry and total platelets CD40 ligand protein content by Western blotting were examined under the same conditions in all objects. The CD40L positive rate and total CD40L content in each group were compared, respectively. RESULTS: The platelet CD40L positive rate and plasma sCD40L concentration in hypertriglyceridemia group were significant higher than those in control group (P<0.01). Followed the TG concentration decreased, the platelet CD40L positive rate and plasma sCD40L concentration decreased after the treatment of fenofibrate, the same as the total platelets CD40L content which was significant higher in hypertriglyceridemia group than that in control group in vitro (P<0.05). No effect of wy14643 on the total CD40L content expression was observed in vitro. CONCLUSION: Hypertriglyceridemia plasma stimulates immune-activation of platelets both in vitro and in vivo. sCD40L may mainly come from CD40L on platelet membrane. PPARα activator of fenofibrate may inhibit the immune-activation of platelets by reducing the concentration of plasma TG, but PPARα activator WY14643 cant inhibit the expression of CD40L and CD40L in vitro.

Aqueous extract of Dracocephalum tanguticum Maxim. (DtM ),when given ig or ip to experimental hypoxia mice,markedly increased their tolerance to normobaric and hypobaric hypoxia. Erythrocyte superoxide dismutasc (SOD ) activity of mice or rats determined at high altitude (animaquing mountain 4700 m above sea level ) showed an elevated dismutation activity of peroxide anions. At an experimentally simulatcd altitude of 6000 m above sea level,determunation of MDA, Hb and Hct showed an obvious reduction of all the abnormally elevated criteria. It is suggested that the antihypoxia activity of DTM may be partly due to its free radical scavenging activity
