ABSTRACT
Objective To summarize the effect of the timing of lung transplantation and related treatment measures on clinical prognosis of patients with paraquat poisoning. Methods Clinical data of a patient with paraquat poisoning undergoing bilateral lung transplantation were retrospectively analyzed. Clinical manifestations, auxiliary examination, diagnosis and treatment of this patient were summarized and analyzed. Results A 17-year-old adolescent was admitted to hospital due to nausea, vomiting, cough and systemic fatigue after oral intake of 20-30 mL of 25% paraquat. After symptomatic support treatment, the oxygen saturation was not improved, and pulmonary fibrosis continued to progress. Therefore, sequential bilateral lung transplantation was performed under extracorporeal membrane oxygenation (ECMO). After postoperative rehabilitation and active prevention and treatment for postoperative complications, the patient was discharged at postoperative 50 d. Conclusions The timing of lung transplantation after paraquat poisoning may be selected when the liver and kidney function start to recover. Active and targeted prevention of potential pathogen infection in perioperative period and early rehabilitation training contribute to improving clinical prognosis of lung transplant recipients.
ABSTRACT
Objective@#To analyze the impact of Pringle’s maneuver on postoperative serum inflammatory mediator levels and prognosis in hepatitis B virus-related hepatocellular carcinoma (HBV related HCC) patients.@*Methods@#A retrospective study was conducted on 157 HBV related HCC patients who underwent treatment at the Chinese PLA General Hospital from January 2016 to December 2017. There were 128 males and 29 females. The mean age was (54.5±12.1) years. These patients were divided into 106 patients who underwent Pringle’s maneuver (the Pringle’s maneuver group). The remaining patients were in the Occlusion-free group. All patients were detected inflammatory mediator levels including the various interleukins (IL) and were regularly followed up. The recurrence-free survival was evaluated by the Kaplan-Meier method, and compared with the log-rank test. The relationship between the Pringle’s maneuver and risks of postoperative tumor recurrence of these patient were estimated by the univariate and multivariate Cox regression models.@*Results@#On postoperation day 1 and day 3, the serum IL-1 and IL-6 levels of the Pringle’s maneuver group were significantly higher than the Occlusion-free group [5.0(5.0, 12.0)ng/L vs. 5.0(5.0, 5.0)ng/L], [122.0(74.5, 173.8)ng/L vs. 80.0(40.0, 120.0)ng/L]; [5.0(5.0, 10.0)ng/L vs. 5.0(5.0, 5.0)ng/L], [78.3(42.8, 138.5)ng/L vs. 48.1(30.1, 75.0)ng/L]. On day 5, the serum IL-1 and IL-8 levels were also significantly higher than the Occlusion-free group [5.0(5.0, 5.3)ng/L vs. 5.0(5.0, 5.0)ng/L], [100.6 (44.2, 186.5)g/L vs. 68.0(36.3, 112.0)ng/L] (all P<0.05). There were 42 and 27 patients who did not develop recurrence in the Pringle’s Maneuver group and the Occlusion-free group, respectively. The recurrence-free survival rates of the Pringle maneuver group and the Occlusion-free group were 40.0% and 52.9%, respectively. There were no significant differences between the two groups (P>0.05). The multivariate Cox regression model suggested that there was no significant correlation between Pringle’s maneuver and recurrence free survival of these patients with HBV related HCC.@*Conclusions@#Pringle’s maneuver could significantly elevate the postoperative serum IL-1, IL-6, IL-8 levels, but it was not related with an increased risk of postoperative tumor recurrence.
ABSTRACT
Objective To analyze the clinical features of intrahepatic biliary cystadenoma and cystadenocarcinoma.Methods Sixteen patients from Dec.2008 to Dec.2013 were retrospectively reviewed to investigate their clinical manifestations,image features,treatment and prognosis.Results Intrahepatic biliary systadenoma and occured occurred primarily in middle-aged women with no typical clinical manifestations.Image examination is the key method in diagnosis.Surgery is the only method to cure the disease.The procedure depends on its location,and its prognosis is related to complete surgical resection.Conclusion Intrahepatic biliary cystadenoma and cystadeno-carcinoma is a rare tumor occuring mostly in middle-aged women.Image examination is the key method in diagnosis.Complete surgical resection contributes to its better prognosis.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the influence of three primers on the shear bond strength between cast titanium (Ti) and composite resin.</p><p><b>METHODS</b>The disks (n = 40) were cast by commercially pure (CP) Ti, which diameter were 8 mm and thick were 3 mm. The titanium surfaces were polished with silicon carbide sand papers under running water and then treated by sandblasting and acid (4%HF) etching. They were divided into four groups: control group (group A), treated with KH-570 (group B), treated with Alloy Primer (group C), treated with Metal photo primer (group D). After treatment, the specimens were evaluated for their shear bond strengths by universal testing machine. The values were statistically analyzed. The fractured surfaces were observed by scanning electron microscope (SEM).</p><p><b>RESULTS</b>The shear bond strengths of group A, B, C, D were (9.773 +/- 0.67), (11.463 +/- 0.82), (14.224 +/- 0.75), (13.157 +/- 0.73) MPa. There were significant differences in bond strength between A and B, C, D (P < 0.01). B and C, D had significant differences (P < 0.01). C and D had no significant differences (P>0.05).</p><p><b>CONCLUSION</b>KH-570, Alloy Primer, Metal photo primer significantly improve the bond strength of ceramage composite resin to cast titanium. KH-570 group bonding strength is lower than the the Alloy Primer group and Metal photo primer group.</p>

<p><b>OBJECTIVE</b>This study aims to investigate the effects of post-cure heat treatment (PCHT) on the bond strength of Ceramage composite resins for titanium casting using different surface treatments.</p><p><b>METHODS</b>Metal specimens (n=30) were randomly divided into following five groups: polishing (group A), sandblasting (group B), acid etching after sandblasting (group C), PCHT after sandblasting (group D), and PCHT after sandblasting and acid etching (group E). The specimens were then processed and coated with Ceramage composite resins according to the grouping. After treatment, the shear bond strengths and microhardness of the specimens were evaluated. The fracture surface morphology of the titanium-Ceramage composite resin was observed using a scanning electron microscope.</p><p><b>RESULTS</b>The shear bond strengths of groups A to E were (5.92 +/- 0.54), (10.25 +/- 0.55), (14.97 +/- 0.88), (14.41 +/- 0.63), and (19.95 +/- 0.52) MPa, respectively. No statistical difference was found between groups C and D, whereas the rest of the groups showed statistically significant differences (P < 0.01). Visible polymerization residues were found on titanium porcelain metal surface of groups B to E. The microhardness values of groups D and E were higher than those of groups B and C (P < 0.05).</p><p><b>CONCLUSION</b>PCHT significantly improves the bond strength and surface microhardness of Ceramage composite resins for titanium casting.</p>
