To investigate various microRNAs (miRNAs) expression levels in cancer associated fibroblasts (CAFs) of gastric cancer,and to explore the effects of miRNA214 in CAFs on the invasion and migration of gastric cancer cells.Methods The primary CAFs were isolated from human gastric tumor tissues,while the normal fibroblasts (NFs) were from adjacent normal gastric mucosa tissues.Real-time quantitative PCR (RT-PCR) was performed to detect the expression level of miRNAs in CAFs and NFs.The interaction model in vitro between CAFs and MGC-803 (a gastric cancer cell line) was established by Transwell chamber,and then the effects of miRNA-214 in CAFs on MGC-803 invasion and migration were analyzed.Results It was found that the expression level of 18kinds of miRNAs in CAFs was different.Moreover,the expression level of miRNA-214 in CAFs was most observably decreased compared with NFs.Further studies indicated that over-expression of miRNA-214 in CAFs could markedly inhibit the migration and invasion ability of gastric cancer cells in vitro.Conclusion The expression of miRNAs was different between CAFs and NFs,and the miRNA-214 expression in CAFs is markedly reduced compared with NFs.The over-expression of miRNA-214in CAFs could significantly inhibit the migration and invasion ability of gastric cancer cells.Therefore,miRNA-214 in CAFs might act as a tumor suppressor in gastric cancer progression.

Background The protective effects against reperfusion injury of cardioprotective drugs have recently been evaluated and found to be inadequate. Guanxinshutong (GXST), a combination of the traditional herb and Mongolian medicine, is effective and safe in treating angina pectoris in clinical trials. We assess the cardioprotective effects of GXST against myocardial ischemia and reperfusion (MI/R) injury in rats and explore its possible mechanism. Methods Forty-five male Sprague Dawley rats were randomized into three groups: non-MI/R group (Sham, n = 15), MI/R group treated with vehicle (Control, n = 15) and MI/R group treated with GXST (Drug, n = 15). MI/R was induced by ligation of the left anterior descending coronary artery (LAD) for 30 minutes, followed by 2/24 hour reperfusion in the Control and Drug groups. In the Sham group, the LAD was exposed without occlusion. GXST powder (in the Drug group) or saline (in the Control and Sham groups) were administered via direct gastric gavage from 7 day prior to surgery. Blood samples were collected from the carotid artery (10 rats each group) after 2 hours of reperfusion, to determine the levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6) and intercellular adhesion molecule-1 (ICAM-1) using enzyme-linked immunosorbent assays. The animals were then sacrificed and the hearts were harvested for histopathology and western blot analysis. Infarct size was measured in the remaining five rats in each group after 24 hours reperfusion. Results GXST significantly decreased levels of TNF-α, IL-1β, IL-6, ICAM-1, apoptosis index (AI) and infarct size. GXST also obviously inhibited nuclear factor kappa B (NF-κB) activity when compared with the Control group (all P < 0.05). Conclusions GXST is effective in protecting the myocardium against MI/R injury in rats. Its possible cardioprotective mechanism involves inhibition of the inflammatory response and apoptosis following MI/R injury.

OBJECTIVETo explore the clinical effects of lattice ultra pulse carbon dioxide laser combined with traditional Chinese medicine ( Fuchunsan ) on the treatment of postburn hyperplastic scar.
METHODSSixty-three patients with hyperplastic scar after burn injury hospitalized from February 2012 to June 2014 in our department were treated with lattice ultra pulse carbon dioxide laser combined with traditional Chinese medicine (Fuchunsan). Patients were divided into early stage group (E, n = 35), middle stage group (M, n = 25), and late stage group ( L, n = 3) according to the formation time of scar, which was respectively 3 weeks to 3 months, longer than 3 months and less than or equal to 6 months, and 3 to 15 years in groups E, M, and L. The number of times of laser treatment of patients in each group was recorded. The degree of scar pain in patients of the three groups was assessed by the Numerical Rating Scale (NRS) before treatment and after treatment for 1, 2, and 3 times. The scar condition of patients in groups E and M was assessed by the Vancouver Scar Scale (VSS) before treatment and after treatment for 1, 3, and 5 times. Patients in group L did not receive VSS assessment but were evaluated by clinical observation only. Photos of scar in treating area were taken before treatment and after treatment for 3 and 5 times to evaluate the clinical effect. Data were processed with t test.
RESULTSPatients in groups E and M were treated with laser for (4.8 ± 1.1) and (7.7 ± 2.1) times respectively. In group L, the treatment was stopped in 2 patients after laser treatment for 5 times, and 1 patient received laser treatment for 12 times. The degree of pain in patients of groups E and M was alleviated significantly after treatment for one time, and the number of patients scoring 1-4 point(s) in NRS increased from 5 cases to 38 cases. After treatment for 2 and 3 times, the increase in the number of patients scoring 1-4 point (s) in NRS was on a small scale. Before treatment and after treatment for 1 time, VSS scores of patients in groups E and M were similar (with values respectively 0.641 and 0. 082, P values above 0. 05). After treatment for 3 and 5 times, VSS scores of patients in group E were respectively (9.2 ± 0.8) and (7.0 ± 1.1) points, which were significantly lower than those in group M [ (9.7 ± 1.0) and (8.2 ± 1.0) points, with values respectively -1.993 and -4.433 , P < 0.05 or P < 0.01]. After treatment for 3 times, the rate of improvement in appearance was respectively 88.6% (31/35) and 72.0% (18/25) in groups E and M, and it was respectively 100.0% (35/35) and 96.0% (24/25) after treatment for 5 times. No significant effect in appearance was found in the 3 patients in group L.
CONCLUSIONSEarly application of lattice ultra pulse carbon dioxide laser combined with traditional Chinese medicine (Fuchunsan) for the treatment of postburn hyperplastic scar is effective.

Objective To summary and discuss the curative effect and experience of repairing serious and complicated soft tissue defects of traumatic shank by flap or musculocutaneous flap by anatomosis.MethodsFrom October 2009 to December 2011, the wounds of 59 patients suffering from serious and complicated soft tissue defects of traumatic shank were covered by VSD after repeated debridement,when the conditions of the whole bodies were stable and the local acute infection was controlled in the main. Fifty-six patients were repaired by a single flap or musculocutaneous flap attributing to the fresh granulation, three patients were repaired by compound tissue flaps because a single flap was insufficient. Five patients who had no available blood vessels at recipient site were repaired by flaps with bridge cross vascular anatomosis. The compound flaps were no more than 2 pieces, the maximum area of flap was 32 cm × 13 cm, the minimum was 15 cm × 8 cm.Results The flaps of all of 59 cases survived, fifty-seven cases were healed in one stage, two in two stage, one case had complication of infection at donate site due to the hematocele, and was cured by debridement and skin graft. Serious and complicated soft tissue defects of shanks were repaired by reconstruction,damaged limbs were salvaged,the functions of the legs were reserved. Conclusion It is the most effective and irreplaceable way that using flaps and musculocutaneous flaps,by anatomosis with the microsurgery technique, repairs the serious and complicated soft tissue defects of shank, which can shorten course and salvage the damaged limbs.
