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.

0.05) among the three groups in cell proliferation in 1~10 d cultures and in total protein content in 4~7 d cultures. At 4 and 7 days, ALP activity of MG63 cells cultivated on AD-TNZS disks was significantly higher than that of cells on the other samples(P

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 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.

ObjectiveTo observe the effect of patient controlled analgesia (PCA) of with tramadol intravenous and epidural injection after prostate operation.Methods90 patients undergoing prostatectomy were randomly divided into intravenous PCA group (PCIA), epidural PCA group (PCEA) and control group (not using easy pain drug), with 30 cases in each group. The loading dose of tramadol was 1 mg/kg. The severity of pain, incidence of nausea and vomiting, total dosage of tramadol used in 24 h ,and patient's satisfaction were assessed.ResultsThe postoperative pain scores of PCIA group were significantly lower than that of PCEA group. Between two groups, there were no significant differences in the overall satisfaction of pain relief, sedation and vomiting.ConclusionPCA with tromadol is safe and effect after prostate operation, and the effect of intravenous PCA is better than that of epidural PCA.

ObjectiveTo investigate the remote renal injury after liver ischemia-reperfusion(I/R) and the renal protection afforded by propofol.Methods 72 male SD rats were randomly divided into three groups:normol control group, I/R group and propofol group .The animals were killed after 60 minutes ischemia of liver followed by reperfusion for 4 h,2 h. Blood urea nitrogen (BUN) and creatinine (Cr) were detected,and renal histopathologic lesion were observed.ResultsIn I/R group,the serum level of BUN and Cr increased significantly compared with the baseline before liver I/R,while propofol could decrease the serum level of BUN and Cr significantly.ConclusionPropofol can reduce the renal injury during liver I/R.

Famous TCM gynecological experts in the contemporary era represent the highest level of TCM gynecology during modern age.This article studies the academic thoughts of eight famous TCM gynecologic experts according to academic schools.The purpose is to seek the commonness of these academic thoughts and research their characteristics.It is extremely significant in inheriting and developing these doctors′ academic thoughts without sectarianism,which will help to guide the clinical works.

Objective:To evaluate the effect of internal distraction osteogenesis in the treatment of complicated teeth-maxillofacial deformity.Methods:Clinical data of 1 0 cases with complicated teeth-maxillofacial deformity were analyzed retrospectively.In the first stage,the patients were operated by internal distraction osteogenesis.In the second stage,the distractor was removed after 3 to 6 months of consolidation period,followed by other operation for further occlusal reconstruction.Results:All the operations were per-formed as planned.The distraction distance was 7 -70 mm.The distraction process was smooth in all the cases.Occlusion was recon-structed and the deformity was corrected by following operation satisfactorily.Conclusion:Internal distraction osteogenesis is effective in the treatment of complicated teeth-maxillofacial deformity for further occlusal reconstruction and functional repair.

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.
