ObjectiveTo evaluate the impact of video-assisted thoracoscopic surgery (VATS) esophagectomy and routine operation on the short-term quality of life in patients with esophageal cancer. MethodsFrom January 2012 through January 2014, 157 esophageal cancer patients were classified into a VATS group (n=42) and a routine operation group (n=115) in our hospital. All patients in the two groups completed the Chinese versions of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (QLQ)-C30 and QLQ-OES18 at one, six and 12 months after operation separately. ResultsAt the end of 6, 12 months after operation, the evaluation on global health status was higher in the VATS group(68.8±12.3 vs. 62.7±13.7, P<0.05; 76.2±10.4 vs. 68.6±8.8, P<0.05). At the end of 1, 6, 12 months after operation, the scores of symptom pain were less significantly in the VATS group than those in the routine operation group (P<0.05). One month after operation, the score of active ability in the VATS group was higher (P<0.05). At the end of 6, 12 months after operation, the score of emotional function and social role in the VATS group was higher (P<0.05). At the end of 12 months after operation, the score of role function and cognitive function in the VATS group was also higher (P<0.05). ConclusionVATS is of better effect on improving short-term quality of life of esophageal cancer patients compared with routine operation.

Methods Literatures were retrieved from CBM, VIP, CNKI, Wanfang databases by computer. Literatures were enrolled according to inclusion and exclusion criteria, and the quality of studies was evaluated according to the Cochrane Library handbook. The period duration of searching was between the establishment of the databases and March, 2011. Meta-analysis was conducted by RevMan 5.0 software. Results The meta-analysis of 6 included RCT, all ranked C, which involved 388 patients. The Meta-analysis showed that the total effective rate in mannatide plus cisplatin group significantly differed from that in cisplatin group (P＜0.05). There were no significant difference in the adverse reaction of digestive tract between the two intervention groups (P=0.05). The adverse reaction of marrow depression inmannatide plus cisplatin group was much lower than that in cisplatin group (P＜0.05). The increase of KPS in mannatide plus cisplatin group was higher than that in cisplatin group (P＜0.05). Conclusions The analysis indicates mannatide plus cisplatin has a better effect on malignant pleural effusion than single cisplatin. However, the reliability of this review is affected by poor quality of included studies, and large-scale randomized controlled trials of high quality are needed to confirm the conclusions above.

Objective To investigate the expression of aquaporin-1（AQP-1） on pleura in rats with carrageenan-induced pleural effusion and explore the role of AQP-1 in effusion formation.Methods Fifty-six healthy Wistar rats were randomly divided into a normal control group and 6 pleuritis groups（6，12，24，36，48 and 72 h groups respectively）.The rat model of inflammatory pleurisy was induced by injecting l-Carrageenan into the pleural cavity.The expression of AQP-1 on pleura was detected with immunohistochemistry.The mRNA and protein expression of AQP-1 on visceral pleura and parietal pleura were measured by RT-PCR and Western blot assay respectively.The volume of pleural effusions were measured.Results The volume of pleural effusion was 2.10±0.22，4.10±0.15，4.40±0.36，3.20±0.27，2.60±0.18，0.12±0.02 mL in the 6，12，24，36，48 and 72 h pleuritis groups respectively.AQP-1 were mainly expressed on visceral and parietal pleural mesothelial cells and capillary endothelial cells，and significantly increased in all pleuritic rats The mRNA and protein expression of AQP-1 on parietal pleura increased after 6 h and reached peak level at 24 h in pleuritic groups.The mRNA and protein expression of AQP-1 on visceral pleura increased after 12 h and reached peak level at 24 h in pleuritic groups.The expression of AQP-1 on parietal pleura at 12 h and 24 h in pleuritic groups was correlated positively with the volume of pleural effusion（r=0.857，r=0.846，all Plt;0.01）.The expression of AQP-1 on visceral pleura at 24 h in pleuritic groups was positively correlated with the volume of pleural effusion（r=0.725，Plt;0.05）.Conclusion The expression of AQP-1 on pleura were increased in rats with e carrageenan-induced pleural effusion.AQP-1 may play a role in pleural fluid transportation in pleural effusion.
Objective To compare the effects of heparin versus urokinase injection intrapleurally in the management of pleural thickening and adhesion due to tuberculous exudative pleurisy. Methods Sixty patients with tuberculous pleurisy were allocated into three groups randomly. Sodium heparin ( heparin group) , urokinase ( urokinase group) , and 0. 9% saline ( control group) were intrapleurally injected respectively. The concentrations of fibrinogen and D-dimer in pleural effusion were measured before and after the injection. The duration of absorption and the total drainage volume of pleural effusion were recorded. The pleural thickness and adhesion were observed two months after the injection. Results In 72 hours after the intrapleural injection, the concentration of fibrinogen( g/L) in the pleural effusion was significantly increased in the heparin group( 1. 13 ±0. 44 vs 0. 34 ±0. 19, P lt; 0. 001) , and significantly decreased in the urokinase group( 0. 25 ±0. 16 vs 0. 38 ±0. 15, P lt; 0. 05) when compared with baseline. Concentrations of D-dimer in the pleural effusions were significantly higher than those at baseline in both the heparin group and the urokinase group( 57. 0 ±17. 6 vs 40. 0 ±15. 4, P lt; 0. 05; 74. 5 ±16. 4 vs 43. 8 ±14. 9, P lt; 0. 001) . There were no significant differences in the absorption duration of pleural effusion among the three groups( P gt;0. 05) . The total drainage volume of pleural effusion was higher in the heparin group and the urokinase group compared to the control group( P lt;0. 01) . And the total volume of pleural effusion was significantly higher in the heparin group and the urokinase group than that in the control group( 2863 mL and 2465 mL vs 1828 mL,P lt;0. 01) . Two months after the intervention, the pleura were thinner[ ( 1. 37 ±0. 82) mm and ( 1. 33 ±0. 85) mmvs ( 3. 06 ±1. 20) mm, P lt; 0. 01] and the incidence of pleural adhesion was significantly lower[ 15% and 20% vs 50% , P lt; 0. 05] in the heparin and the urokinase groups than those in the control group.Conclusion Intrapleural heparin has similar effects with urokinase for prevention pleural thickness andadhesion in tuberculous pleurisy with good availability and safety.
Objective To investigate the expression of aquaporin-1( AQP1 ) in visceral and parietal pleura in SD rats and to examine the effect of AQP1 on pleural fluid turnover. Methods Five groups( n = 24 ) of SD rats were randomly assigned to received intrapleural injection of dexamethasone,lipopolysaccharide, erythromycin, hypertonic saline and normal saline, respectively. The AQP1 protein in pleural was detected with immunohistochemistry. The mRNA expression of AQP1 under stimulations at different time points was measured by real time RT-PCR. Results AQP1 was immunolocalized predominantly to the microvessels and mesothelial cells of visceral and parietal pleura. The extent of AQP1expression in parietal pleura was less than that in visceral pleura[ ( 4. 14 ±1. 12) ×104 copy /μg vs ( 7. 43 ±2. 02) ×104 copy / μg, P lt;0. 05] . AQP1 expression increased at all phases in the dexamethasone group andthe hypertonic saline group, whereas decreased in the erythromycin group and the lipopolysaccharide group.Conclusion The stimulations of dexamethasone, lipopolysaccharide, erythromycin and hypertonic saline can significantly change the AQP1 expression in pleura, which indicate that AQP1 may contribute to the accumulation and clearance of pleuritic fluids.
【Abstract】Objective To explore the differential diagnostic value of major fibrinolytic parameters in pleural fluid. Methods Tissue-type plasminogen activator( t-PA) and plasminogen activator inhibitor-1( PAI-1) in pleural fluid at the first thoracentesis were measured with ELISA and D-dimer was measured with immunoturbidimetry. Results Eighty-four patients with pleural effusion were enrolled, among which 40 with malignant effusion, 33 with infectious effusion and 11 with transudative effusion. t-PA level was higher in malignant and transudative pleural fluid than that in infectious pleural fluid[ ( 52. 49 ±31. 46) ng /mL and ( 58. 12 ±23. 14) ng /mL vs ( 37. 39 ±22. 44) ng /mL, P lt; 0. 05] , but was not statistically different between malignant pleural fluid and transudative ( P gt; 0. 05) . PAI-1 level was higher in malignant and infectious pleural fluid than that in transudative [ ( 164. 86 ±150. 22) ng/mL and ( 232. 42 ±175. 77) ng/mL vs ( 46. 38 ±16. 13) ng/mL, P lt; 0. 01] , but was not statistically different between malignant and infectious pleural fluid( P gt;0. 05) . D-dimer levels in the three types of pleural fluid were significantly different, which was ( 23. 66 ±25. 18) mg/L, ( 6. 36 ±10. 87) mg/L and ( 66. 90 ±42. 17) mg/L in malignant, transudative and infectious pleural fluid, respectively. As single-item detection for malignant pleural fluid, the cutoff of t-PA was gt; 38. 7 ng/mL( area under ROC curve was 64. 0 ) , with sensitivity of 60. 0% , specificity of 63. 6%, positive predictive value of 66. 7%, negative predictive value of 56. 8% and accuracy of 61. 6% .The cutoff of D-dimer was lt; 27. 0 mg/L( area under ROC curve was 85. 5) , with sensitivity of 84. 8% ,specificity of 72. 5% , positive predictive value of 85. 3% , negative predictive value of 71. 8% and accuracy of78.1%. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of combined examination( t-PA + D-dimer) were 92. 5% , 60. 6% , 74. 0% , 87. 0% , 78. 1% , respectively.Conclusions The t-PA, PAI-1 and D-dimer levels are significantly different in the three types of pleural fluid. The detection of fibrinolytic parameters in pleural fluid, especially the value of D-dimer,may be helpful in the differential diagnosis of pleural effusion.
