Objective To evaluate the effect of cardamonin on acute lung injury induced by hemorrhagic shock and resuscitation (HSR) in rats.Methods Thirty-two male Sprague-Dawley rats,aged 18-24 weeks,weighing 200-250 g,were divided into 4 groups (n =8 each) using a random number table:sham operation group (group Sham);group HSR;cardamonin group (group CA);cardamonin + adenosina A2A receptor antagonist ZM241385 group (group CZM).Bilateral common carotid arteries were only cannulated in group Sham.The left common carotid artery was cannulated for blood-letting until mean arterial pressure was reduced to 35-45 mmHg and maintained at this level for 30 min,and the animals were then resuscitated by infusion of shed blood and normal saline two-fold volume of shed blood to establish HSR model in HSR,CA and CZM groups.ZM241385 5 mg/kg was injected intraperitoneally at 30 min before blood-letting in group CZM,and cardamonin 75 mg/kg was injected intraperitoneally immediately after the beginning of resuscitation in CA and CZM groups.The rats were sacrificed at 2 h after completion of resuscitation,bronchoalveolar lavage fluid (BALF) was collected for determination of neutrophil count,and lungs were removed for microscopic examination of the pathological changes and for determination of wet/dry lung weight ratio (W/D ratio),contents of tumor necrosis factor-alpha (TNF-ct),interleukin-1 (IL-1β) and IL-6 (by enzyme-linked immunosorbent assay) and expression of adenosine A2A receptors in lung tissues (by Western blot).Results Compared with group Sham,the neutrophil count in BALF,W/D ratio and contents of TNF-α,IL-1β and IL-6 were significantly increased,the expression of adenosine A2A receptors was significantly down-regulated in group HSR,and the neutrophil count in BALF and contents of TNF-α and IL-6 were significantly increased (P＜0.05),and no significant changes were found in W/D ratio,content of IL-1β,and expression of adenosine A2A receptors in group CA (P＞0.05).Compared with group HSR,the neutrophil count in BALF,W/D ratio and contents of TNF-α,IL-1β and IL-6 were significantly decreased,the expression of adenosine A2A receptors was significantly up-regulated (P＜0.05),and the pathological changes were significantly attenuated in group CA,and no significant changes were found in the parameters mentioned above in group CZM (P＞0.05).Compared with group CA,the neutrophil count in BALF,W/D ratio and contents of TNF-α,IL-1β and IL-6 were significantly increased,the expression of adenosine A2A receptors was significantly down-regulated (P＜0.05),and the pathological changes were aggravated in group CZM.Conclusion Cardamonin can attenuate acute lung injury induced by HSR in rats,and activated adenosine A2A receptors and inhibited inflammatory responses are involved in the mechanism.

Objective To investigate the relative motion between the femoral component and the tibial insert through the technology of fluoroscopy and digital model.Methods Sixteen female patients (16 knees) with knee osteoarthritis were performed TKA (GENESIS Ⅱ) from July 2007 to June 2008.The mean age was 66.4 years (range from 56 to 76 years).All patients were followed up 48 months to 60 months,with the mean of 56±3 months.The postoperative clinical function was evaluated by Knee Society Score (KSS).To match the digital model to the imaging data of fluoroscopy using 2D-3D automatic registration technology and reconstruct motion of the knee after TKA.The movement of contact position between femoral medial and lateral condyle and tibial insert and tibial internal rotation during flexion were measured.The contact time and range between femoral cam and tibial post were analyzed.Results The cases were statistically improved in KSS postoperatively,knee score was 93±5 and function score 88±13.The range of movement for femoral medial condyle was 8.5±2.5 mm,and the lateral condyle was 9.5±4.8 mm,the range of tibial internal rotation was 2.5°±8.4°.The contact of cam and post was observed after 30°-40° flexion of the knee,and the range was 8.0±1.8 mm.The greater tilting angle of the tibial plateau was,the later contact between cam and post happened.Conclusion The kinematics of tibiofemoral joint after TKA is different from the kinematics of normal knee.With knee flexion within 10°-30°,femoral medial condyle moves forward.When flexion is greater than 40°,medial and lateral condyle begins rollback.The time of contact of cam and post is relative to tibial prosthesis slope.

OBJECTIVE:To establish the method for the determination of tigecycline (TGC) in human plasma. METHODS:After precipitated by acetonitrile,the plasma sample was determined by LC-MS/MS. Using d9-TGC as internal standard,Kromasil C18 column was used with mobile phase consisted of water (containing 0.05% TFA)-acetonitrile (gradient elution) at flow rate of 0.6 ml/min,column temperature of 40 ℃. The ion transitions were performed under ESI positive MRM model at m/z 586.3→513.2 and m/z 595.3→514.3 for TGC and internal standard,respectively. RESULTS:The linear range of TGC was 25-2 000 ng/ml (r=0.999 8),and lowest quantification limit was 25 ng/ml;intra-day and inter-day RSD was 3.15%-7.23%,and relative error was-4.53%-10.48%. Plasma sample kept stable after 3 times of freezing and thawing cycle,at room temperature for 24 h,in automat-ic sample injector for 24 h and freezing for 42 d (RSD<15%). Plasma concentration of TGC was 0-438.0 ng/ml in one patient with pan-drug resistant bacteria infection(0-12 h after administration). CONCLUSIONS:The developed method is accurate,sensi-tive and specific,and can be used for plasma concentration determination of TGC and pharmacokinetic study.

Objective To investigate the role of transient receptor potential melastatin 7 (TR PM7) in the protective role of sevoflurane preconditioning against hippocampal neuron injury caused by oxygen glucose deprivation (OGD).Methods Hippocampal neurons were harvested from postnatal day 1 SD rats,and randomly divided into 5 groups:control group (group C),sevoflurane group (group Sev),oxygen-glucose deprivation group (group OGD),sevoflurane+ OGD group (group SD) and sevoflurane+OGD+bradykinin group (group B).To build up the model of OGD,the neurons were cultured in a deoxygenated glucose-free medium and exposed to 95％ N2 and 5％％ CO2 in an anaerobic chamber equilibrated at 37℃ for 1.5 h,followed by replacement with glucose containing medium and return to a standard incubator for additional 24 h.The neurons in group C received no treatment.Group OGD was preconditioned with 2 ％ sevoflurane for 1 h.The neurons in group OGD were subjected to OGD.Group SD was preconditioned with 2％ sevoflurane for 1 h,followed by OGD at 24 h after the sevoflurane exposure.The neurons in group B was incubated in a medium supplemented with 200 μmol/L bradykinin (the selective agonist of TRPM7),followed sequen tially by the preconditioning of 2％ sevoflurane for 1 h and then OGD challenge.Twenty-four hours after re-oxygenation,The relative neuronal cell viability was determined by MTT assay,the neuronal apoptotic rate was analyzed by TUNEL assay,the protein expression of TRPM7 was detected by Western blot,the mRNA level of TRPM7 was estimated by real-time PCR,the neuronal release of IL-1β and TNF-α in the serum was measured by ELISA.Results Compared with group C,the mR NA and protein levels of TRPM7,the neuronal apoptotic rate,the mRNA and supernatant protein levels of IL-1β and TNFα were significantly up-regulated in group OGD (P＜0.05),whereas the cell viability was decreased (P＜0.05).Compared with group OGD,the mRNA and protein levels of TRPM7,the neuronal apoptotic rate,the mRNA and supernatant protein levels of IL1β and TNF-α were significantly down-regulated in group SD (P＜0.05),whereas the cell viability was increased (P＜0.05).Compared with group SD,the mRNA and protein levels of TRPM7,the neuronal apoptotic rate,the mRNA and supernatant protein levels of IL-1β and TNF-α were significantly up-regula ted in group B (P＜0.05),whereas the cell viability was decreased (P＜0.05).Conclusion Sevoflurane attenuates apoptosis and inflammatory responses induced by OGD via reduction of the overex pression of TRPM7 in the hippocampal neurons.

Objective To investigate the levels of oxidative stress in liver tissues of hepatocelluar carcinoma(HCC)patients after transcatheter arterial chemotherapy(TAC).Methods Immunohistochemistry streptavidin biotinylated peroxidase(S-P)method was used to detect the cellular levels of 8-hydroxy-2'-deoxyguanosine(8-OHdG),p53 and p21~(waf1/cip1).Eighty-nine HCC patients were divided into TAC group(39 cases)and Non-TAC group(50 cases).15 Non-HCC liver tissues served as controls.Result 8-OHdG level was higher in Non-TAC group than that in TAC group in tumor tissues (F=9.516,P＜0.05),with that being the lowest in control group(F=9.516,P＜0.01);8-OHdG levels in cancer tissues were significantly higher than that in tumor surrounding tissues in both TAC group (t=7.101,P＜0.001)and Non-TAC group(t=8.020,P＜0.001),there was no significant difference of 8-OHdG levels between para-tumor tissues and controls.The levels of 8-OHdG between tumor and its surrounding tissues in TAC group(r=0.651,P＜0.001)and non-TAC group(r=0.493,P＜0.01)was in positive correlation.The difference of p53 levels in cancer tissues in TAC group and Non-TAC group were not statistically significant and p53 was not detected in para-tumor tissues.The difference of p21~(waf1/cip1) levels among TAC group,Non-TAC group and controls was statistically significant,the levels of p21~(waf1/cip1) in normal group was the highest(F=13.459,P＜0.001),followed by that in TAC and Non-TAC group in cancer tissues(TAC vs.Non-TAC group,P＜0.01);p21~(waf1/cip1) expression in normal controls was significantly higher than that in both TAC and Non-TAC group in para-tumor tissues(F=16.613,P＜0.001).The correlation of p21 ~(waf1/cip1) levels between tumor and its surrounding tissues was significant in non-TAC group(r=0.872,P＜0.001).Conclusions Oxidative stress levels in HCC tumor tissues were higher than in para-tumor tissues and non-HCC liver tissues.Cancer cells probably survive chemotherapy by fortifying oxidative stress repair mechanism.
