ObjectiveTo introduce the operative technique of pedicle evolution from isolated perforator to perforator-plus-adipofascial,and investigate its clinical results in venous drainage and safety in distallybased sural flaps.MethodsAfter identifying the proper viable perforators,the whole flap was designed in an eccentric propeller shape,with the perforating vessels corresponding to the pivot point.The proximal larger blade was a fasciocutaneous flap, while the distal smaller blade was a subdermal vascular plexus flap,preserving at least a quarter area of adipofascial tissue around the perforator.From January 2008 to December 2010,we performed distally perforator-adipofascial pedicled sural fasciocutaneous propeller flap in 12 patients,with 180 degrees rotation to cover foot and ankle defects.Postoperatively,flap swelling,survival and functional recovery were evaluated. Results There were 7 posterior tibial artery perforator flaps from the posteromedial and 5 peroneal artery perforator flaps from the posterolateral sural region. The proximal fasciocutaneous flap measured 4 cm × 8 cm-6 cm × 18cm, and the distal cutaneous flaps measured 2 cm × 2cm-4 cm × 4 cm.Flap swelling was noted under grade 2 in 9 cases,grade 3 in 2 cases,and grade 4 in 1case with some distal superficial skin necrosis,which occurred in the largest flap in our series.All flaps survived eventfully.After average 13 months follow up,the wound were cured successfully,and all patients recovered walking and shoe wearing function. ConclusionPedicle evolution by keeping some adipofascial tissue around the pivot perforator, can preserve more venous return routes and relieve flap swelling. This technique should be recommended in perforator pedicled propeller flaps,as it enhances flap safety,and without increasing the difficulty of 180 degrees rotation.

OBJECTIVETo assess the clinical outcomes of balloon kyphoplasty assisted with calcium phosphate cement (CPC) in treating osteoporotic vertebral fractures (OVF).
METHODSFrom January 2009 to January 2011, 26 patients with osteoporotic vertebral fractures were treated with balloon kyphoplasty assisted with CPC, including 31 vertebrae. There were 15 males and 11 females with an average age of (71.67 +/- 4.36) years old (ranged from 60 to 89 years). Course of disease was from 0.5 to 7 days with an average of 3.2 days. Clinical outcomes were assessed by the visual analogue scale (VAS) and the oswestry disability index (ODI). Vertebral height loss and kyphotic angle were measured by X-rays.
RESULTSAll patients were followed up for 10 to 24 months with an average of 18 months. Before operation, 24 hours after operation and at final follow-up, VAS scores were 7.91 +/- 1.20, 3.22 +/- 1.12, 1.92 +/- 0.83, respectively; ODI scores were 40.00 +/- 1.15, 17.00 +/- 2.12, 13.00 +/- 1.42, respectivesly; vertebral heights were (18.21 +/- 3.21), (23.82 +/- 3.10), (21.85 +/- 3.24) mm, respectivesly; vertebral kyphosis angles were (18.21 +/- 3.21) degrees, (7.42 +/- 3.13) degrees, (10.01 +/- 3.11) degrees, respectivesly. There was significant difference between preoperation and 24 hours after operation, and between final follow-up and preoperation (P < 0.05). There was no significant difference between final follow-up and 24 hours after operation (P > 0.05).
CONCLUSIONBalloon kyphoplasty assisted with calcium phosphate cement (CPC) is effective for the treatment of osteoporotic vertebral fractures (OVF), which can expeditiously relieve pain and effectively rebuild height of vertebral body and kyphotic angle, and also has advantages of minimal trauma and good security.

AIM: To study the effect of double gene transduction mediated by lentiviral vectors on the characteristics of human embryonic stem cells (hESCs). METHODS: Using the backbone from inducibal dual and excisable transgene vector (iDuet101) , lentiviral vectors overexpressing cytotoxic T lymphocyte - associated molecule - 4 immuno-globulin (iDuet101 - CTLA4Ig) , indoleamine 2, 3 dioxygenase (iDuet101 - IDO) , and ubiquitin - C promoter - lueifer-ase - ires - puromycin ( ULIP) were constructed and packaged according to the standard recombinant techniques. Human embryonic stem cells (hESCs) were first transduced with iDuet101, iDuet101 - CTLA4Ig or iDuet101 - IDO, then, after the selection, were transduced again with ULIP. The expression and function of the exogenous genes were detected. Immu-nohistochemistry, RT - PCR and flow cytometry were applied for detection of embryoid bodies ( EB) formation in vitro and in vivo teratoma formation. RESULTS: Double - transduced hESCs showed typical shape of cell clones and positive staining of tumor rejection antigen -1 - 60 ( Tra -1 - 60 ) and octomer transcription factor - 4 ( OCT - 4 ). The formation of EB was observed, in which a - fetoprotein (AFP), paired box gene 6 ( Pax6) and Musashi 1 ( MSI1) were positively expressed. The cells formed teratomas, and the luciferase signals existed until 28 days after xeno - transplantation. CONCLUSION : Double transduction of non - transcriptional factors mediated by lentiviral vectors does not affect the cell growth rate and their differentiation ability.

Objective To investigate cholecystokinin (CCK),carbachol, and vasoactive intestinal peptide(VIP)stimulating peptide chain elongation in mouse pancreatic acini in vitro and its molecular mechanism. Methods ~3H-lecucine incorporation assay was used to measure the basal and secretagogues-stimulated pancreatic acini elongation rates. Western blot was applied to analyse the effect of phosphorylation of the elongation factor 2 (eEF2) and the eEF2 kinase. MEK inhibitor (PD98059), SAPK/p38 inhibitor (SB202190), and mTOR inhibitor (rapamycin) were used to respectively block MEK, SAPK/p38, and mTOR intracellular pathways or the phosphatase inhibitor (calyculin A) pretreatment before CCK treatment. Results All secretagogues except VIP increased the peptide chain elongation in mouse pancreatic acini in vitro. All secretagogues except VIP inhibited the phosphorylation level of eEF2 on Thr-56 and increased the phosphorylation level of eEF2K on Ser-366, which might correlate with their activation status. MEK inhibitor PD98059 partially reversed the dephosphorylation of eEF2 induced by CCK, as did treatment p38 MAPK inhibitor SB202190, mTOR inhibitor rapamycin, and the phosphatase inhibitor calyculin A.Conclusion CCK increases peptide chain elongation via inducement of dephosphorylation of eEF2 and eEF2 kinase phosphorylation in pancreatic acini in vitro. CCK-induced dephosphorylation of eEF2 in pancreatic acinar cells involves MEK, SAPK/p38, and mTOR, the three intracellular pathways.
