The expression and clinical significance of lncRNA-uc003jsd.1 in congenital microtia / 中华整形外科杂志

Objective@#To investigate the expression of long non-coding RNA(lncRNA) uc003jsd.1 in congenital microtia and its clinical significance.@*Methods@#Real-time quantitative polymerase chain reaction (Real-time PCR) was used to detect the expression of lncRNA-NR_028308 in the residual ear cartilage and normal ear cartilage of 8 patients with microtia.@*Results@#The expression of uc003jsd.1 was significantly higher in the residual ear cartilage (P=0.015) than paired normal tissues.@*Conclusions@#LncRNA-uc003jsd.1 is up-regulated in the cartilage of the congenital microtia, suggesting a certain relationship with the development of congenital microtia.

Deep analysis of methylation profile in congenital microtia and verification of the differential genes / 中华整形外科杂志

Objectives@#To explore the differences in signal pathway and gene expression related to the pathogenesis of congenital microtia by the in-depth analysis of DNA methylation profiling of auricular chondrocytes from congenital microtia patients.@*Methods@#Genome wide methylation profile of congenital microtia was obtained by MeDIP chip technology, and analyzed by Gene ontology (GO) and Pathway analysis. The gene expression levels of Wnt1 and Wnt11 were evaluated by Real-time PCR in the auricular cartilage from the healthy side and affected side of the congenital microtia patients , and healthy controls.@*Results@#The GO and Pathway assay showed that Wnt signal pathway was enriched in differential methylated levels. The Wnt1 and Wnt11 genes were with higher methylation in the promoter region and CpG islands in healthy control group than that in microtia group, in addition the methylation level in the affected side auricular cartilage was lower than that in the healthy side. There was no difference in Wnt1 and Wnt11 gene expression in microtia patients and healthy controls. The higher Wnt11 gene expression was detected in the affected side residual cartilage tissues than in the healthy side cartilage tissues of the same congenital microtia patient.@*Conclusions@#The over expression of Wnt11 during embryonic development might be associated with the pathogenesis of congenital microtia. The mechanism of the difference in methylation levles of Wnt11 affecting pathogenesis of congenital microtia needs further research.

Correction of preauricular depression using the composite flap of microtic cartilage and soft tissue in tragus reconstruction / 中华整形外科杂志

Objective@#To summarize the clinical effect of using the composite flap of microtic cartilage and soft tissue in tragus reconstruction to correct preauricular depression.@*Methods@#From January 2015 to November 2016, we corrected preauricular depression of 523 patients with congenital microtia that were treated with tragus reconstruction by using the composite flap of residual ear cartilage and soft tissue.@*Results@#All the composite flap of residual ear cartilage and soft tissue were transplanted successfully. No blood circulation disorder and significant contracture occurred. All patients were followed up for 6-14 months with an average of 10 months. The reconstructed tragus looked projective and the preauricular depression was corrected, demonstrating a similar looking to the healthy side. The patients were satisfied with the results.@*Conclusions@#The residual ear tissue could form the composite flap of residual ear cartilage and tissue. Using the composite flap to fill the preauricular depression was effective, which was not easily absorbed. The residual ear tissue is the best resource for filling the preauricular depression. It should not be discarded in ear reconstructive surgery, but reserved for the next operation for tragus reconstruction.

The impact of elastic chest belt on chest wall deformity after costal cartilage harvesting / 中华整形外科杂志

Objective@#To evaluate whether restricted breathing movement by wearing elastic chest belt within half a year postoperatively could decrease the incidence of chest wall deformity after costal cartilage harvesting.@*Methods@#The contour of chests of the patients receiving the third-stage operation of auricular reconstruction was assessed 1 year after costal cartilage harvesting with history collection and physical examination. The incidence of costal wall deformity was summarized and compared by wearing elastic chest belt or not within half a year postoperatively. Logistic regression was used to analyze the significance of results.@*Results@#Thirty-eight eligible patients were enrolled in the study. The incidence of chest wall deformity in patients wearing chest elastic chest belt as requested for half a year was lower (64.7% vs. 95.2%), and the difference was statistically significant, OR 10.9, 95%CI[1.16, 102.60], P=0.037.@*Conclusions@#Restricted breathing movement by wearing elastic chest belt within half a year postoperatively could decrease the incidence of chest wall deformity following costal cartilage harvesting through decreasing the traction force caused by respiratory muscles and intrathoracic negative pressure.

Study on the Mechanism of Aurantii Fructus Immaturus and Its Main Active Ingredients in Promoting Gastrointestinal Motility of Model Rats with Spleen Deficiency / 中国药房

OBJECTIVE:To study the mechanism of Aurantii fructus immaturus(AFI)and its main active ingredients in pro-moting gastrointestinal motility of model rats with spleen deficiency. METHODS:170 rats were randomly divided into blank group (10 rats) and modeling group (160 rats),rats in modeling group was induced models with spleen deficiency by bitter cold diar-rhea+irregular diet. After modeling, rats were randomly divided into model group, naringin (NA) low-dose, medium-lose, high-dose groups(3.267,6.535,13.070 mg/mL),neohesperidin(NE)low-dose,medium-lose,high-dose groups(3.865,7.730, 15.460 mg/mL),synephrine(SY)low-dose,medium-lose,high-dose groups(0.252,0.504,1.008 mg/mL),compatibility groups with 3 monomer ingredients (NA-NE-SY) low-dose,medium-lose,high-dose and AFI water decoction low-dose,medium-lose, high-dose groups(0.104,0.208,0.416 g/mL,calculated by crude drug),ig,once a day,10 mL/kg,for 7 d. After the last admin-istration,gastrin (GAS) in serum,and acetylcholine (ACh),motilin (MTL),substance P (SP),vasoactive intestinal peptide (VIP)levels in plasma were detected. RESULTS:Compared with blank group,GAS level in serum and ACh,MTL,SP levels in plasma in model group were reduced(P<0.01),VIP level in plasma was increased(P<0.05). Compared with model group,ex-cept for the GAS level in serum showed no obvious change in NA high-dose group and SY doses groups,other medicine groups were obviously increased (P<0.05 or P<0.01);the ACh levels in serum were obviouly increased in NE high-dose group,SY high-dose group and AFI water decoction low-dose group(P<0.01). MTL levels in plasma were obviously increased in NE medi-um-dose,high-dose groups,SY high-dose group,compatibility low-dose,medium-dose groups and AFI water decoction medi-um-dose,high-lose groups (P<0.05);SP levels in plasma were obviously increased in NA low-dose,medium-dose groups and NE doses groups(P<0.05 or P<0.01);VIP levels were reduced in NA low-dose group,SY high-dose group and AFI water decoc-tion low-dose,medium-lose groups(P<0.05). CONCLUSIONS:AFI may promote the gastrointestinal motility of model rats with spleen deficiency by promoting the secretion of GAS,ACh,MTL,and inhibiting the secretion of VIP;there are differences be-tween AFI and the 3 monomer ingredients in regulation of gastrointestinal hormones.
