Objective To analyse the difference of effects of different tidal volume mechanical ventilation strategies in infants with severe congenital heart disease after curative.Methods Sixty-eight cases were chosen from CICU of Anhui Provincial Children's Hospital during Oct 2010 to Jan 2012.Thirty-two cases in A group were used in ventilation strategy by lower tidal volumes (6 ～ 10 ml/kg),36 cases in B group were used in ventilation strategy by larger tidal volumes (10 ～ 15 ml/kg).The time of mechanical ventilation,duration of ICU stay and postoperative complications were compared between the two groups.Results The time of mechanical ventilation of B group was shorter than that of A group [(8.6 ± 2.5) d vs (11.7 ± 3.2) d],duration of ICU stay of B group was shorter than that of A group [(11.4 ± 4.8) d vs (15.6 ± 5.7) d],there were statistical differences between two groups(P ＜ 0.0l).The incidence rate of ventilator associated pneumonia and pneumothorax were 6.3％ and 3.1％ in A group,which were 5.6％ and 5.6％ in B group,there were no statistical differences between two groups (P ＞ 0.05).Conclusion The effects of mechanical ventilation with larger tidal volumes is better than that with lower tidal volumes in infants with congenital heart disease postoperative therapy.

Aim To investigate the effect that catalpol intervenes macrophage polarization mediated by mouse mesangial cells(MMCs) stimulated by advanced glycation end products(AGEs).Methods RAW264.7 macrophages and MMCs were co-cultured in vitro and divided into model group(100 mg·L-1 AGEs), control group(100 mg·L-1 BSA), catalpol(0.1, 1.0, 10.0 μmol·L-1) group, and aminoguanidine(1.0 μmol·L-1) group which was set as positive control.After being incubated with catalpol for 1 h, MMCs were stimulated by AGEs for 23 h.The proliferation-inhibition rate of MMCs was measured by MTT assay.MCP-1 in supernatant liquid of MMCs was detected by ELISA method.The expression of iNOS, CD16/32, TNF-α, COX-2, CD206 and Arg-1 was detected by Western blot.Simultaneously, the percentage of iNOS and CD206 was also measured by flow cytometry.Results AGEs could increase the level of MCP-1 secreted by MMCs.The expression of iNOS, TNF-α, CD16/32 and COX-2 protein of macrophage was up-regulated after MMCs stimulated by AGEs, while the expression of CD206 and Arg-1 was down-regulated.After being intervened by catalpol, these effects could be reversed.All the changes were concentration-related.Conclusions Catalpol can inhibit macrophages M1-type polarization process and promote M2-type polarization, which may be mediated through MCP-1 secreted by MMCs after AGEs stimulation.Catalpol can ameliorate inflammation and relieve diabetic kidney injury.

Objective To study the value of image-guided radiotherapy (IGRT) in lung cancer. Methods From Mar. 2007 to Dec. 2007,58 patients with lung cancer were treated with IGRT. Set-up er-rors in each axial direction was calculated based on IGRT images of each patient. The change of GTV was e-valuated on both cone-beam CT and CT simulator images. Results Twenty-two patients with left lung cane-er,30 with right lung cancer,5 with mediastinal lymphanode metastasis and one with vertebra metastasis were included. The set-up error in x,y and z axes was (0.02±0.26) cm, (0.14±0.49) cm and ( -0. 13± 0.27) cm, respectively,while the rotary set-up error in each axis was -0.15°± 1.59°, -0.01°± 1.50° and 0.12°±1.08°, respectively. The set-up errors were siguifieantly decreased by using of IGRT. GTV movement was observed in 15 patients (25.9%) ,including 5 with left upper lung cancer. GTV moving to the anterior direction was observed in 9 patients,including 4 with]eft upper lung cancer. GTV reduced in 23 (44.2%) patients during treatment. Asymmetric GTV reduction of 22 lesions was observed,with a mean re-ductive volume of 4.9 cm3. When GTV began to shrink,the irradiation dose was 4 -46 Gy,with 20 -30 Gy in 9 patients. Conclusions The use of IGRT can significantly reduce set-up errors. GTV movement and reduction are observed in some cases. The time to modify the target volume needs to be further studied.
