Objective To compare the hemodynamic responses to orotracheal intubation with GlideScope video laryngoscope (GSVL), Macintosh laryngoscope (MDLS) and fiberoptic bronchoscope (FOB) .Methods Sixty ASAⅠorⅡpatients (21 male, 39 female) aged 18-50 yrs weighing 45-90 kg scheduled for elective plastic surgery under general anesthesia with tracheal intubation and mechanical ventilation were randomly divided into 3 groups ( n = 20 each): GSVL group; MDLS group and FOB group. The patients were premedicated with intramuscular scopolamine 0.3 mg. Anesthesia was induced with midazolam 0.05 mg?kg-1 , fentanyl 2?g?kg-1 , propofol 2 mg?kg-1 and vecuronium 0.1 mg?kg-1 and maintained with 1% isoflurane and 60% N2O-40% O2 . Orotracheal intubation was performed at 2 min after intravenous vecuronium. Noninvasive BP and HR were recorded before and after induction of anesthesia, during tracheal intubation and at 1, 2, 3, 4, 5 min after tracheal intubation was completed. The HR and SBP product (RPP) was calculated. Results The intubation time was significantly longer in FOB group than in MDLS group (P

Abstract? AIM: Through the establishment of penetrating keratoplasty model of rats, to detect the role and its mechanism of immature dendritic cells with IL-10 gene modified.? METHODS: Allogeneic penetrating corneal transplantation in rat model was performed. SD rats were randomly divided into positive control group, GFP-DC group, 8-DC and IL-10-GFP-DC group.At 3d before keratoplasty, the rats were given tail intravenous injection with the same amount of PBS, bone marrow 8-DC ( DC had cultured for 8d ) from donor Wistar rats, GFP-DC after 48h transfection and IL-10-GFP-DC.Rats were observed under slit-lamp for corneal graft cases every day, and recorded rejection index and corneal graft survival time.At 14d after keratoplasty, pathologic and immunohistochemical examinations were performed.?RESULTS:Compared with GFP-DC group and 8-DC group, corneal graft survival time of IL-10-GFP-DC group was significantly longer ( P<0.01 ); at 14d after keratoplasty, corneal opacity, edema, neovascularization and rejection index of IL-10 -GFP-DC group were significantly lower (P<0.01).Pathological examination showed that in the three experimental groups corneal inflammation was lighter than the positive control group without significant central graft neovascularization. Immunohistochemistry showed: compared to the positive control group, GFP-DC group and 8-DC group, CD4+, CD8+, CD25+, IL-2+, NK+and NF-κB+positive cells in IL-10-GFP-DC group were lower(P<0.01).? CONCLUSION: After donor -derived immature dendritic cells pretreated, corneal graft survival was significantly prolonged, successfully induced corneal transplantation tolerance. CD4+, CD8+, CD25+, IL-2+, NK+and NF-κB+positive cells are involved in corneal allograft rejection regulation, IL-10-GFP-DC may reduce CD4+, CD8+, CD25+, IL-2+, NK+and NF-κB+positive cell infiltration, inhibit corneal transplant rejection.

ObjectiveTo observe the functional recovery of shoulder joint and the reduction of posterior dislocated humeral head in children with shoulder joint internal rotation contracture and humeral head posterior dislocation secondary to brachial plexus birth palsy treated by a modified surgical procedure through the anterior combined posterior approach of the shoulder. MethodsNinteen patients,ranging in age from 2.5 to 8.5 years (average 5 years),suffered posterior dislocation of the shoulder joint secondary to internal rotation contracture in brachial plexus birth palsy. The gleno-humeral joint deformity was confirmed by X-ray and CT examination and classified as type Ⅳ in 15 eases and typeⅤin 4 cases according to the modified water's criteria.The surgical procedure was as follows:the contracture soft tissue around the anterior of shoulder joint was released firstly through the anterior approach, and the posterior-inferior capsule of the shoulder was exposed and separated with the pseudoglenoid through the posterior approach,the humeral head was reduced by external rotation the arm,then the posterior-inferior capsule was retighten.A plaster cast was used to fix the shoulder at the neutral position of 0° for 4 weeks. ResultsAfter 12 to 36 months follow up(average of 20 months), the Mallet score of the shoulder was from 11.4 ± 1.7 (range 7-16)preoperative to 15.5 ± 1.8(range 13-19) postoperative,the difference was significantly (P < 0.05).The central relocation of humeral head was achieved in 16 patients, but the humeral head was still dislocated to posterior in 3 cases.ConclusionsThe posterior-inferior capsule was separated with the pseudo-glenoid and retighten through the posterior approach,and reduction of the humeral head by soft tissue releaseing through the anterior approach can recover the concentric relationship of gleno-humeral joint and improve the function of shoulder joint with posterior dislocation secondary to internal rotated contracture deformity in brachial plexus birth palsy.

Objective To investigate changes ane clinical significance of renal pathomorphology ane transforming growth factor-β1(TGF-β1 ),connective tissue growth factor(CTGF)of rats with eifferent stages of eiabetes mellitus(DM). Methods Thirty-six SD rats were raneomly eivieee into control ane DM group. Rats in DM group were given streptozotocin(STZ)at a eose of 65 mg/ kg boey weight ane rats in control group were given same amount citric acie/ soeium citrate buffer solution. Rats were killee at 4th,12th ane 24th weeks after DM moeels establishment. The renal hyeroxyproline concentration(HPC)was measuree. Masson′s trichrome was performee to observe perivascular collagen area(PVCA). Glomerular collagen eeposition score(GCDS),tubular interstitial eisease score(TIDS)in kieney interstitial tissue were measuree. Immunohistochemical staining were usee to measure the expression of type Ⅰ ane Ⅲ collagen,TGF-β1 ,CTGF. Renal path morphology change were observee with light microscope ane transmission electron microscope. Results (1)HPC levels of rats in DM group at 4th,12th,24th weeks were(216. 50 ± 10. 05)μg/ g,(267. 67 ± 11. 29)μg/ g,(340. 67 ± 39. 22)μg/ g,higher than that of control group((123. 00 ± 6. 00)μg/ g,(158. 50 ± 8. 89)μg/ g,(201. 00 ± 7. 69)μg/ g). The PVCA score in DM group were higher than that of control group( 4 weeks:(0. 45 ± 0. 07)vs (0. 96 ± 0. 11);12 weeks:(0. 60 ± 0. 06)vs(1. 65 ± 0. 18);24 weeks:(0. 72 ± 0. 07)vs(2. 63 ± 0. 0. 40);P< 0. 05). Meanwhile the scores of GCDS ane TILS in DM group)at 4th,12th,24th weeks increasee comparee with control group(4 weeks:((0. 34 ± 0. 03)vs(0. 14 ± 0. 01))× 103 / μm2 );12 weeks:((0. 49 ± 0. 03)vs (0. 26 ± 0. 04))× 103 / μm2;24 weeks:((0. 62 ± 0. 06)vs(0. 33 ± 0. 03))× 103 / μm2 )). The expression of CollagenⅠane Collagen Ⅲ in DM group were higher than that of control at 4,12,24 weeks after DM moeel establishment(Collagen Ⅰ:4 weeks:((4. 56 ± 0. 75)vs(1. 34 ± 0. 34))× 103 / μm2;12 weeks:((6. 07 ± 0. 74)vs(2. 17 ± 0. 12))× 103 / μm2;24 weeks:((7. 22 ± 0. 19)vs(3. 00 ± 0. 33))× 103 / μm2;CollagenⅢ:4 weeks:((3. 44 ± 1. 41)vs(1. 58 ± 0. 24))× 103 / μm2;12 weeks:((5. 60 ± 1. 34)vs(2. 95 ± 0. 41)) × 103 / μm2;24 weeks:((6. 22 ± 0. 18)vs(3. 27 ± 0. 27))× 103 / μm2 )),ane the eifferences between the groups all significant(P < 0. 05). Diffuse thickening of glomerular capillary basement membrane ane interstitial collagen hyperplasia in eiabetic rats were observee by electron microscope.(2)TGF-β1 expression in DM group were(2. 16 ± 0. 50)× 103 / μm2 ,(5. 31 ± 0. 25)× 103 / μm2 ,(6. 44 ± 0. 74)× 103 / μm2 respectively at 4th, 12th,24th weeks after DM moeel establishment,higher than that of control group((1. 18 ± 0. 15)× 103 / μm2 , (2. 99 ± 0. 25)× 103 / μm2 ,(3. 28 ± 0. 66)× 103 / μm2 )ane the eifferences were significant(P < 0. 05). The same trene was also seen in terms of CTGF expression((6. 02 ± 1. 39)vs(2. 32 ± 0. 87))× 103 / μm2 ,((6. 51 ± 0. 51)vs(3. 96 ± 0. 92))× 103 / μm2 ,((7. 89 ± 1. 46)vs(4. 58 ± 1. 02))× 103 / μm2;P < 0. 05) Conclusion Early eiabetic rats show renal fibrosis ane it may be relatee with overexpression of CTGF ane TGF-β1.
