Objective:To compare the clinical effects between axillary approach, periareolar approach and inframammary fold approach in breast augmentation.Methods:Two hundred and eleven patients in our department from Jan. 2016 to Jan. 2018 were involved in this study. According to the surgical approach, the patients were divided into the axillary approach group, periareolar approach group and inframammary fold approach group. Postoperative pain, incision scar, drainage fluid and several complications were observed in three groups.Results:Postoperative VAS score of patients in inframammary fold approach and periareolar approach group was lower than that in the axillary approach group ( F=70.93, P<0.05), and postoperative drainage fluid was lower than in the axillary approach group. No diffrences were found in postoperative scar score among the three group ( P>0.05), and the nipple areola sensory disorder in the inframammary fold approach group was less. Conclusions:Breast augmentation of inframammary fold approach has the advantages of relatively hidden incision, short surgical approach, direct vision operation, mild pain, less surgical injury and low postoperative complications. It is worthy of being promoted.

Objective To investigate the effect of unfractionated heparin (UFH) on the expression of heme oxygenase-1 (HO-1) in intestinal mucosa of mice with sepsis.Methods Thirty-six male C57BL/6J mice were randomly divided into sham group,cecal ligation and puncture (CLP) group and UHF group,n =12 in each group.Model of intestinal injury in sepsis was induced by CLP.In sham group,the mice were exposed without ligation of cecum.In UFH group,the mice were treated intravenously with 8 U of UFH via the tail vein half an hour before the operation and 12 hours after the surgery respectively.Six mice in each group were randomly chosen at 4 hours and 24 hours after operation to collect inferior vena venous blood samples and terminalileum tissues.The serum levels of interleukins (IL-1 β,IL-6),and tumor necrosis factor-α (TNF-α) were determined by enzyme linked immunosorbent assay (ELISA).The serum level of D-lactate was determined by colorimetry.Pathological changes of ileum tissue and Chiu score were observed after hematoxylin eosin (HE) staining.The HO-1 expression was detected immunohistochemically.Results In sham group,no significant changes in the serum levels of IL-1 β,IL-6,TNF-α and D-lactate were observed.Twenty-four hours after the operation,the structure of intestinal mucosa was basically normal without obvious pathology change and no HO-1 positive cells were found.The serum levels of IL-1 β,IL-6,TNF-α,and D-lactate in CLP group were gradually increased,and they were significantly increased as compared with sham group [IL-1 β (ng/L):40.87±2.88 vs.22.60±2.05 at 4 hours,113.73±3.96 vs.22.07±2.74 at 24 hours;IL-6 (ng/L):63.89±3.26 vs.44.89±3.38 at 4 hours,176.56±5.45 vs.45.76±4.02 at 24 hours;TNF-α (ng/L):194.62± 14.13 vs.152.05±6.22 at 4 hours,599.62± 10.20 vs.155.90± 14.18 at 24 hours;D-lactate (mmol/L):0.24± 0.02 vs.0.19 ± 0.01 at 4 hours,0.33 ± 0.04 vs.0.20 ± 0.02 at 24 hours,all P ＜ 0.05].Twenty-four hours after the operation,edema and inflammation in ileal mucosa,intestinal villi structural damage were observed,the Chiu score was significantly higher than those in the sham group [4.5 (3.0-5.0) vs.0 (0-1.0),P ＜ 0.05],and a small amount of HO-1 positive cells were localized in the intestinal mucosa.Compared with CLP group,the serum levels of IL-1 β,IL-6,TNF-α,and D-lactate of UFH group were significantly decreased [IL-1 β (ng/L):31.53 ± 2.90 vs.40.87 ± 2.88 at 4 hours,61.13 ± 2.80 vs.113.73 ± 3.96 at 24 hours;IL-6 (ng/L):51.16 ± 5.68 vs.63.89 ± 3.26 at 4 hours,81.16 ± 4.54 vs.176.56 ± 5.45 at 24 hours;TNF-α (ng/L):171.76± 5.60 vs.194.62± 14.13 at 4 hours,328.48 ± 10.79 vs.599.62± 10.20 at 24 hours;D-lactate (mmol/L):0.21 ±0.01 vs.0.24±0.02 at 4 hours,0.24±0.02 vs.0.33±0.04 at 24 hours,all P ＜ 0.05].Twenty-four hours after the operation,intestinal injury was ameliorated,the Chiu score was significantly lower [1.5 (1.0-5.0) vs.4.5 (3.0-5.0),P ＜ 0.05],and HO-1 positive cells in the intestinal mucosa was remarkably increased.Conclusion UFH can enhance the expression of HO-1 in intestinal mucosa,reduce the release of inflammatory factors,ameliorate the intestinal inflammatory response,and thus play a protective role in intestinal tissue in mice with sepsis.

OBJECTIVETo investigate the development of the electrophysiological property of bushy cells in the anterior ventral cochlear nucleus (AVCN) of neonatal Sprague Dawley (SD) rats.

METHODSThe development of action potential and spontaneous miniature excitatory postsynaptic currents (mEPSCs) in AVCN bushy cells were investigated by whole-cell patch-clamp technique in SD rats during the postnatal days 5-21 (P5-21). The half band width of the action potential (AP), 10%-90% risetime and decay tau of the mEPSCs were analyzed.

RESULTSThe AP of the bushy cells became faster with age from P5 to P21 and stopped changing around the period of hearing onset, as evidenced by the alteration of half band width of the AP. The time accuracy of mEPSCs of the bushy cells also increased with age and stabilized around hearing onset as shown by briefer 10%-90% rise time and decay tau of mEPSCs in P14/P21 than in P7.

CONCLUSIONThe functional refinement of the bushy cells in the AVCN precedes hearing onset in neonatal rats.

Objective : To investigate the effect of isoprene cysteine carboxymethyltransferase (ICMT) gene on the migration and invasion of salivary adenoid cystic cancer cells (SACC) and the related mechanism, to provide experimental evidence for molecular targeted therapy of SACC. Methods: Adenoid cystic cancer cells SACC-LM and SACC-83 were cultured in vitro, and siRNA was transfected into human SACC-LM and SACC-83 cells (experimental group) by transient transfection of a liposome vector. A blank control group and negative control group were set up respectively (transfected NC-siRNA). qRT-PCR was peformed to measure the mRNA expression of ICMT and RhoA in each group after transfection and to determine the silencing efficiency. The expression of ICMT, membrane RhoA, total RhoA, matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9) and Rho associated with coiled helical binding protein kinase 1 (ROCK1) in each group was detected by Western blot. The proliferation abilityies of SACC cells was detected by CCK-8 assay. The migration and invasion ability of SACC cells were detected by comparing the relative healing area of cell scratch assay and the number of Transwell assay cells. Results: After transfection of ICMT-siRNA into SACC-LM and SACC-83 cells, the expression of ICMT gene and protein in the experimental group was significantly decreased compared with the negative control group and blank control group (P<0.05), but there were no significant differences in the expression of RhoA gene and total protein among all groups (P>0.05). The expression of RhoA membrane proteins, ROCK1, MMP-2, MMP-9 in the experimental group was significantly decreased compared with that in the negative control group and blank control group (P<0.05). Cell proliferation ability was significantly decreased (P<0.05). The migration and invasion abilities were significantly decreased (P<0.05). Conclusion In vitro silencing of ICMT gene can effectively inhibit the migration and invasion of human SACC-LM and SACC-83 cells, and the mechanism may be related to RhoA-ROCK signaling pathway.
