Objective To investigate the changes of extravaacular lung water during the perioperative period of orthotopic liver trans-plantation. Methods 24 consecutive patients with end-stage fiver disease undergoing orthotopie liver transplantation (OLT) were studied. In all patients a 5 French fiberoptic catheter with a thermistor was placed in the brachial artery and connected to the PiCCO system. Extravascular lung water (EVLW) and intrathoracic blood volume (ITBV) were monitored. After induction of anesthesia and achievement of stable hemodynamic and respiratory conditions, the baseline values of hemedynamic data, ITBV and EVLW were recorded. The patients were studied during the anhepatic stage, the Ist hour and 2nd hours after reperfusion of the graft. Final measurements of all the values were immediately determined after operation. Results EVLW remained statistically unchanged during the whole study period in all patients though all of them were increased, compared to normal values. EVWL was positively correlated with ITBV (r = 0. 822, P < 0. 05). Conclusion The changes of EVLW during perioperative period of orthotopic fiver transplantation were very little. Circulative volume overload may be perhaps the most important cause of the increase of EVLW.

OBJECTIVE: To investigate the expression of Testin gene, and analyze its possible relationship with the clinicopathological features of human nasopharyngeal carcinoma. METHOD: The expression of Testin in nasopharyngeal carcinoma tissues were detected by immunohistochemistry methods, semi-quantitative reverse transcription polymerase chain reaction and Western blot. The correlations of Testin to clinicopathologic features of nasopharyngeal carcinoma were analyzed. RESULT: The positive expression rate of Testin in NPC biopsy tissue was 37.8% (17/ 45), while it was 88.9% (40/45) in the normal tissue; The expression of Testin mRNA was significantly lower than that in the normal tissue (P < 0.01); The expression levels of Testin protein in the NPC biopsy tissue by Western blot were lower than that in the normal tissue (P < 0.01); The expression of Testin in the tumor tissue had no significant correlation with sex, age (P > 0.05); but it had significant correlation with lympho node metastasis, distant metastasis and differentiation degree. CONCLUSION The decreased expression of Testin gene may play an importmant role in the development of nasopharyngeal carcinoma. And thus Testin gene might be a novel candidate of tumor-suppressor. It may be an objective marker for prognostic factor and malignant level for nasopharyngeal carcinoma.

Objective To observe the changes in acid-base balance and the contents of electrolytes in patients during liver transplantation to explore the relationship between such changes and ASA grading, and to look for an optimal anesthetic intervention. Methods Arterial pH, PaO_2, PaCO_2, HCO~-_3, BE, K~+, Ca~ 2+ , Na~+, and glucose were monitored in 89 patients undergoing liver transplantation at four specific periods: before anesthesia (T_0), after skin incision (T1), 10 minutes before reperfusion (T_2), and 10 minutes after reperfusion (T_3). Changes in blood acid-base and electrolyte parameters of the patients with different ASA status were compared. Result The pH and BE in ASA V patients was significantly lower at T_0, T_1, T_2 and T_3, and HCO~-_3 was lower in ASA V at T_3. The PaCO_2 in ASA V patients was significantly higher at T_0, T_1 and T_2. The Na~+ content in ASA V patients was significant higher at T_2 and T_3. At T_0 and T_1, the glucose level in ASA Ⅳ and Ⅴ were significant higher than in ASAⅢ. Significant differences in pH, PaCO_2, HCO~-_3, BE and glucose level were observed at different stages of the surgical procedure. The pH, BE and HCO~-_3 were significantly lowered at T_2 and T_3. Mean glucose and HR levels were gradually increased from T_1 to T_3. Conclusion Patients with advanced ASA grades are more prone to acid-base and electrolyte disturbances during reperfusion of the liver transplant. High ASA grades contitute an increased risk for cardiovascular collapse after reperfusion, calling for proper treatment.

Objective:To analyse the causes of early implantation failure and the therapeutic measures with re-implantation after the failures.Methods:6 cases of implantation failure including early infections,loosening and non-osteointegration were reviewed and trea-ted by re-implantation therapy,and the causes of failure were discussed and the effects of re-treatment were evaluated.Results:2 cases were found to be with infection of adjacent teeth after implantation and were treated by removal of the implant,socket curettage,root ca-nal therapy(RCT)and antibiotics followed by reimplantation.Implant loosening and non-osteointegration were observed in 4 cases, which were treated by the similar methods for the implant socket.Reimplantation was successful in all 6 cases followed-up for 1 -3 years.Conclusion:Preventive measure for implantation failure should include indication selection,control of infections in adjacent teeth and periodontosis,use of GBR technic and so on.Re-implantation following proper treatment of adjacent teeth and the socket of implant is effective for the treatment of implantation failure.

Objective To approach the effect of protective mechanical ventilation on acute lung injury after orthotopic liver transplantation, by observing changes of plasma markers of lung injury and inflammatory mediators.Methods Sixty patients scheduled for liver transplantation under general anesthesia, 42 males and 18 females, aged 21-62 years, weighing 43-80 kg, ASA physical status Ⅱ-Ⅳ, were randomly divided into 2 groups: protective mechanical ventilation group (group P) and unprotective mechanical ventilation group (group U).Pulmonary artery blood for plasma markers of lung injury and inflammatory mediators were collected at the following time points: before operation (T1), 3 hours after mechanical ventilation (T2), 2 hours (T3) and 4 hours in neohepatic stage (T4).These mediators included clara cell secretory protein (CC16), surfactant proteins (SP-D), soluble receptor for advanced glycation end-products (sRAGE), TNF-α, IL-6 and IL-8.Moreover, blood gas results were recorded at these 7 time points: T1-T4, 2 hours after operation (T5), before tracheal extubation (T6) and 2 days after operation (T7).The postoperative awakening time, tracheal extubation time, ICU stay time and the incidence of ALI were recorded.Results Compared with T1, plasma level of CC16 in the two groups increased at T2 and T3 (P<0.05 or P<0.01), however, plasma level of SP-D, sRAGE, TNF-α, IL-6 and IL-8 did not increase until T3 (P<0.01).Moreover, plasma level of sRAGE, TNF-α, IL-6 and IL-8 at T4 were higher than those at T1 (P<0.05 or P<0.01).Compared with T1, OIs in the two groups increased at T2, T5 and T6 (P<0.05 or P<0.01), while decreased at T4 in group P (P<0.01) and at T3 and T4 in group U (P<0.01).In group P, patients showed a lower plasma level of CC16 at T2 and T3 (P<0.05 or P<0.01), a higher OI at T3 (P<0.05) and an earlier tracheal extubation after operation [(8.9±3.2) h vs (9.3±2.8) h, P<0.05] compared with group U.There was no significant difference of acute lung injury incidence between the two groups after operation, which was 5(16.6%) and 7 (23.3%), respectively.Conclusion Protective mechanical ventilation may promote oxygenation index, and shorten tracheal extubation time, thus protect lung function of patients in liver transplantation to some extend.

Objective To evaluate the effects of lung-protective ventilation on acute lung injury after liver transplantation.Methods Sixty patients of both sexes,aged 21-64 yr,with body mass index of 18-28 kg/m2,of American Society of Anesthesiologists physical status Ⅱ-Ⅳ,scheduled for elective orthotopic liver transplantation,were divided into 2 groups (n =30 each) using a random number table:conventional mechanical ventilation group (group CMV) and lung-protective ventilation group (group LPV).In group LPV,the patients were mechanically ventilated (tidal volume 6-8 ml/kg,respiratory rate 10-15 breaths/min,positive end-expiratory pressure 3-10 cmH2 O),and lung recruitment mnaneuver was pertormed every 2 h.Before skin incision (T1),at 3 h of preanhepatic phase (T2),at 30 min of anhepatic phase (T3) and at 2 and 4 h of neohepatic phase (T4.5),bronchoalveolar lavage fluid (BALF) was collected and blood samples from the radial artery were simultaneously collected for determination of tumor necrosis factor-alpha and interleukin-8 concentrations in BALF and serum by enzyme-linked immunosorbent assay.At 2 h after operation (T6),before tracheal extubation (T7) and at 2 days after operation (T8),blood samples from the radial artery were collected for blood gas analysis,and oxygenation index was calculated.The concentrations of serum Clara cell secretory protein 16,surfactant protein D and soluble receptor for advanced glycation end-products were determined at T1-T8 using enzyme-linked immunosorbent assay.The postoperative emergence time,extubation time,duration of intensive care unit stay and development of acute lung injury were recorded.Results Compared with group CMV,the cxtubation time was significantly shortened,serum concentrations of Clara cell secretory protein 16 at T2,T3,T6 and T7,serum surfactant protein D concentrations at T5 and serum concentrations of soluable receptor for advanced glycation endproducts at T5 and T6 were decreased (P＜0.05),and no significant change was found in tunor necrosis factor-alpha and interleukin-8 concentrations in serum and BALF at each time point or postoperative incidence of acute lung injury,oxygenation index,emergence time and duration of intensive care unit stay in group LPV (P＞0.05).Conclusion Although lung-protective ventilation dose not decrease the development of acute lung injury after liver transplantation,it attenuates lung tissue injury to some extent.
