AIM:To evaluate the regulatory effect of microRNA-132 ( miR - 132 ) in human umbilical vein endothelial cell ( HUVEC) .
●METHODS: ln vitro cultured human umbilical vein endothelia cells in hypoxic environment for 6h, then maintained under normal oxygen condition for 3h, 6h, 12h, 24h. miR-132 and peroxisome-proliferator-activated receptor-γ coactivator-1α ( PGC-1α) expression was detected by quantitative Real - time polymerase chain reaction and Western blot analysis. Human umbilical vein endothelial cells transfected miR-132 mimic and miR-132 inhibitor( anti-miR-132 ) were measured by quantitative Real-time polymerase chain reaction and Western blot.
●RESULTS: miR - 132 and PGC - 1α expression was significantly ( P < 0. 01 ) upregulated in the hypoxic environment of cells at 3h compared with the normal oxygen condition. After cells transfection, the hypoxic environment the miR-132 and PGC-1α expression were markedly increased compared with the normal oxygen condition. The cells transfected miR- 132- mimic, the expression of the miR-132 and PGC-1α were higher than that of transfected anti-miR-132 and contrast group ( P<0. 01).
●CONCLUSION:miR-132 level is highly expressed in the HUVEC under hypoxia and may be an effect of regulation for PGC-1α.

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.

Objective To observe the changes of serum calcium, phosphorus, calcium-phosphorus product and para-thyroid hormone(PTH)levels after treatment with different concentrations of calcium dialysate in combination with calcitri-ol. Methods Thirty-six patients on maintenance hemodialysis were randomly divided into Dca1.25 group and Dca1.5 group, 18 cases in each group. Patients took different doses of calcitriol on the different values of PTH basis. Changes of se-rum calcium, phosphorus, calcium-phosphorus product,PTH and bone alkaline phosphatase (BAP) levels were recorded re-spectively on four time points from prior treatment and 1, 3 and 6 months of therapy. The levels of systolic blood pressure (SBP) and diastolic blood pressure (DBP) were also observed. Results There was an interaction between treatment effects and time effects in serum calcium, phosphorus, calcium-phosphorus product levels in two groups (P＜0.05). With the dura-tion of treatment, there was a trended to decrease and increase respectively in DCa 1.25 group and DCa 1.5 group, and trend-ed to stabilize for therapy 3 to 6 months. There was no interaction between serum PTH and BAP levels and time effects in two groups. There was no statistical difference in simple treatment effects and time effects. The serum PTH level showed a trend of increase gradually in DCa1.5 group with the duration of treatment. In DCa 1.25 group, the serum PTH level trended to stabilize after 3-month therapy and showed a trend of decrease gradually. There was an interaction between treatment effects and time effects in SBP in two groups, but no interaction in DBP. There was a significant difference in SBP before and after treatment in two groups. The level of SBP reduced tardily with time of treatment and reduced significantly after 3 and 6-month therapy. Conclusion The application of DCa1.25 dialysate in combination with calcitriol decreased serum calci-um effectively and kept the lower limit of normal value, which increased tolerability of active vitamin D and calcium carbon-ate therapy, and decreased SBP in maintenance hemodialysis patients.

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.

Objective To test the reliability and validity of ICF Core Sets for Chinese COPD patients.Methods Fifty-two COPD patients were measured with ICF Core Sets for COPD patients and SF-36. For reliability test, the internal consistency was analyzed and expressed by Cronbach α coefficients and split-half reliability. For va-lidity test, the content validity and criterion validity were analyzed and expressed with Spearman rank correlation coef-ficients. Results For body function, body structure and activity and participation, there were good internal consis-tency (Cronbach α coefficients 0. 698～0.957). For environmental factors Crnnbach α coefficient and split-half reli-ability did not exist. Most items of body function, activity and participation and body structure possessed good content validity. There was concurrent validity for ICF components of body function, body structure and activity and participa-tion with SF-36, FEV1/FVC, COPD grade and health self-assessment. The environmental factors demonstrated poor reliability and validity. Conclusion The ICF Core Sets for COPD patients showed good reliability and validity. It is a good comprehensive functional measurement scale for COPD patients, but it is necessary to test the generality of this result, and some items need to be adjusted.

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.
