Objective To optimize the processing conditions of Manchuiran Dutchmanspipe Stem with alkali. Methods The combination of radial basis function ( RBF) and response surface methodology ( RSM) was used to investigate the influence of NaHCO3 , concentration, duration and cycles of processing on the content of aristolochic acid. Results The optimal process was achieved when Manchuiran Dutchmanspipe Stem was soaked for 3 cycles in 0. 05 mol·L-1 NaHCO3 solution, for 24 hours in each cycle. The removal rate of total aristolochic acid approached to 83. 74%. Conclusion The combination of RBF and RSM provided a new method and good guidance for further toxicity attenuation for Manchuiran Dutchmanspipe Stem.

Objective To investigate the effect of systematic training on the enhancement of knowledge and behavior on tumor-free technology among newly-employed nurses in operation room.Methods Fifteen nurses newly-employed for the operating room of the Affiliated Hospital of Luzhou Medical College were trained with theory teaching,techniques training and nursing rounds. The test on non-tumor knowledge and questionnaire on beliefs and behaviors were used to assess the post-training effects.Result The scores on tumor-free knowledge,beliefs and tumor-free behaviors were all significantly improved compared with pre-training (P<0.01). Conclusion Systematic training of tumor-free technology may improve the mastery of tumor-free knowledge and skills and thus form a good tumor-free concept so that they can keep tumor-free techonology in practice.

Objective To investigate the effect of full-dose and half-dose aprotinin on perioperative inflammatory response in patients undergoing off-pump coronary artery bypass grafting (CABG) .Methods Thirty-nine patients aged 50-65 yrs undergoing off-pump CABG were randomly divided into 3 groups (n = 13 each):Ⅰcontrol group (C);Ⅱfull-dose aprotinin group (A-full) andⅢhalf-dose aprotinin group (A-half) . In groupⅡ( A-full) aprotinin 2?106 KIU in 100 ml normal saline (NS) was infused over 30 min after induction of anesthesia followed by aprotinin infusion at 0.5?106 KIU?h-1 until the end of surgery. In group A-half, half the amount of aprotinin administered in group A-full was given. In control group only NS was administered. Blood samples were taken before operation (T1,baseline) , 0.5 h after completion of vascular anastomosis (T2) and 2, 6, 18 h after operation (T3-5), for determination of plasma concentrations of IL-10, IL-6 and troponin (TnI) .Results The 3 groups were comparable with respect to age, M/F ratio, duration of operation and the number of bypass grafts. Plasma concentrations of IL-10, IL-6 and TnI were significantly increased after operation as compared to the baseline values (T0) in all 3 groups. The plasma concentrations of IL-10, IL-6 and TnI were significantly lower and postoperative blood loss smaller in the 2 aprotinin groups than in the control group; but they were not significantly different between the two aprotinin groups. Conclusion Both full-dose and half-dose aprotinin can inhibit the inflammatory response to CABG, reduce myocardial injury and postoperative blood loss. Half-dose aprotinin is recommended in patients undergoing off-pump CABG.

AIM To investigate protective effects and mechanism of tanshinones on ischemia-like injury models. METHODS Six ischemia models including hypoxia, hypoglucose, oxidant injury, caffeine injury, nitric oxide neurotoxicity and excitatory amino acid injury were used to assay the anti-ischemic roles of tanshinones in cultured primary cortex neurons. The changes of injuried cortex neurons were observed by the way of morphological examination, and live neurons of crystal violet staining were measured according to absorbent index. RESULTS it was found that tanshinones possessed obvious protective effects on primary neurons in injury models by the way of morphological e~nation. Crystal violet staining also indicated that tanshinones increased number of live neurons in injury models significantly. The protective effects of tanshinones on models of oxidant injury, caffeine injury and NMDA injury were superior to other injury models. CONCLUSIONS 83.0 ?mol? L- 1 tanshinones protected rat cortex cells fm all injury models effectively in vitro.

BACKGROUND: Hydroxyapatite/β-tricalcium phosphate biphasic ceramic bone has good cel compatibility, but its mechanical properties are poor. OBJECTIVE: To construct chitosan/ or calcium alginate/biphasic ceramic bone scaffolds and to detect their mechanical properties and cytocompatibility. METHODS: Different concentrations of chitosan (2%, 4%, 7%, 10%) or calcium alginate (3%, 4%, 5%, 7%) were mixed with biphasic ceramic bone to prepare chitosan/biphasic ceramic bone scaffold and calcium alginate/biphasic ceramic bone scaffold. Their morphology and structure, coagulation time, anti-dissolution properties, shear force, compressive strength and cel compatibility were detected. RESULTS AND CONCLUSION: (1) Coagulation time: with the concentration increase, the initial and final setting time of these two kinds of composite scaffolds were prolonged to some extent. (2) Scanning electron microscopy: these two kinds of composite scaffolds showed porous microstructures with different pore sizes. (3) Anti-dissolution properties: the calcium alginate/biphasic ceramic bone scaffold (3%, 4%, 5%, 7%) and chitosan/biphasic ceramic bone scaffold (7%, 10%) had good anti-dissolution properties in the liquid. (4) Mechanical strength: with the concentration increase, the shear force and compressive strength of the calcium alginate/biphasic ceramic bone scaffold were reduced. (5) Cel compatibility: the cytotoxicity of chitosan/ or calcium alginate/biphasic ceramic bone scaffolds was graded as 0-1 or 2-3, respectively. These results show that the chitosan/biphasic ceramic bone scaffold has better mechanical properties and cel compatibility than the calcium alginate/biphasic ceramic bone scaffold.
