Background:Due to absence of visible endobronchial target,the diagnostic yield of flexible bronchoscopy for peribronchial lesions has been unsatisfactory.Convex probe endobronchial ultrasound (CP-EBUS) has allowed for performing real-time transbronchial needle aspiration (TBNA) of enlarged hilar and mediastinal lymph nodes and therefore could also be used as a means of diagnosing proximal peribronchial lesions.Methods:We retrospectively analyzed the results related to 72 patients who underwent CP-EBUS for peribronchial lesions without endobronchial involvement and adjacent to three-grade bronchi based on chest computed tomography (CT) scan.We recorded the images during EBUS as well as the diagnostic results of TBNA and conventional-transbronchial lung biopsy/brush (C-TBLB/b),and final diagnoses were based on pathologic analysis and follow-up.Results:In all cases,the mass was able to be identified using EBUS in 97.2％ patients (70/72) who were performed with EBUS-TBNA + C-TBLB/b.Sixty-six patients had a final diagnosis,80.0％ patients (56/70) had malignancies,and 14.3％ patients (10/70) had benign disease.In malignancies,the diagnostic yield of C-TBLB/b was 57.1％ (32/56) and in EBUS-TBNA was 85.7％ (48/56),whereas pathologic diagnosis reached 94.6％ when EBUS-TBNA was combined with C-TBLB/b.C-TBLB/b + EBUS-TBNA also exhibited stronger potency ofhistolytic diagnosis for malignancies than either EBUS-TBNA or C-TBLB/b alone.Furthermore,there are data supporting the value of EBUS-TBNA for the diagnosis of benign lung disease.Conclusion:The combined endoscopic approach with EBUS-TBNA and C-TBLB/b is an accurate and effective method for the evaluation of peribronchial lesions,with better results than using each technique alone.

OBJECTIVEThe study was to reveal the vascular changes in three different supercharging flap models. From this study, we want to investigate which vessel, the artery or the vein is more important in elongating perforator flap survival and why.

METHODSTwelve rats were divided into three experimental groups. The left side flaps in all groups were pedicle using xiphoid perforator as control group. The right side flaps were supercharging experimental group. Group I, flap supercharged based on artery and vein of pubis perforator. Group II, flaps supercharged based on artery of pubis perforator. Group III, flaps supercharged based on vein of pubis perforator. Near-infrared fluorescent angiography was performed using SPY imaging system pre-and-aft operation and all angiography videos were compared and analyzed.

RESULTSShowed in angiography video of SPY, in control group and vein supercharging group, blood supply could be observed the immediately reducing, and almost be disappeared the amount of perfusion to distal area. It shows relatively constant necrosis in the distal side of control group and vein supercharging group, and the necrosis of vein supercharging group smaller than these of control group. In artery, vein supercharging group and artery supercharging group, blood perfusion could be observed separately perfusion in the upper and low area of flap. There are complete survival showed on the artery supercharging group and artery and vein supercharging group.

CONCLUSIONSThese findings indicated that congestive flap necrosis attribute to insufficiency of arterial blood. Arterial inflow was demonstrated more important for improved survival of distal flap than venous outflow.

OBJECTIVETo investigate the effect of autologous dermal-fat strip grafting in penile augmentation and elongation.

METHODSFrom May 2004 to December 2010, 24 patients underwent penile enhancement with free dermal-fat strip grafting. Through suprapubic incision, the superior suspensory ligament and part deep suspensory ligament are cutted off to lengthen the penis. The resulted dead space is filled with the autologous dermal-fat strip (6.0-9.5 cm in length, 1.2-1.5 cm in width and 0.6-0.8 cm in depth) to enhance the penis.

RESULTSPrimary healing was achieved in 23 cases. Incisional fat liquefaction happened in one case which healed after dressing change. The penile appearance was satisfactory both at rest or erection. The penile length and circumference increased by 2.5-4.8 cm (average, 3.2 cm) and 1.8-3.0 cm (average, 2.4 cm), respectively. 18 patients were followed up for 3 months to 5 years. All the patients were satisfactory on the cosmetic and functional results. No complication happened.

CONCLUSIONSIt is safe and effective for penile augmention and elongation with autologous dermal-fat strip grafting and disconnection of penile suspensory ligament.

INTRODUCTIONThe role of soluble OX40 ligand (sOX40L) in adult bronchial asthma is unclear. This study aims to determine the serum concentrations of sOX40L in adult patients with bronchial asthma, and discussed its relationship with pulmonary function.

MATERIALS AND METHODSWe measured the pulmonary function using the spirometer and detected the serum concentrations of sOX40L by enzyme linked immunosorbent assay (ELISA) in 19 healthy persons in the control group, 58 acute asthmatic adult patients who were grouped according to their disease severity: 18 mild grade, 24 moderate grade, 16 severe grade, and 24 persons in a stable asthmatic group.

RESULTSThe serum concentrations of sOX40L in asthmatic adult patients (6.80 ± 4.95 ng/L) were distinctly higher than those in the control group (3.98 ± 2.83 ng/L, P <0.05), and they were negatively correlated with pulmonary function indexes (FEV1%, FVC%, FEV1/FVC) (r = -0.754, P <0.01, r = -0.557, P <0.01, r = -0.457, P <0.01, respectively). Moreover, the serum concentrations of sOX40L showed obvious differences among control, mild, moderate, and severe groups (3.98 ± 2.83, 4.87 ± 1.89, 6.97 ± 5.91, 8.71 ± 5.18 ng/L, respectively; P <0.01). The concentrations of sOX40L decreased to the same extent as the control group after therapeutic treatments were provided to the asthmatic adult patients.

CONCLUSIONThe concentrations of sOX40L were found to be high in adult asthmatic patients and were associated with the severity of the disease. Therefore, sOX40L could be a potential inflammatory mediator in the pathogenesis of asthma.

Objective To compare the effects of intracoronary infusion of mononuclear stem cells (MNCs) or mesenchymal stem cells (MSCs) in patients with dilated cardiomyopathy (DCM).Methods DCM patients with left ventricular ejection fraction ( LVEF ) ＜ 40％ were randomized to intracoronary infusion of MNCs [ (5.1 ± 2.0) × 108,n =16] or MSCs [ (4.9 ± 1.7 ) × 108,n =17 ] or equal volume normal saline ( n =20 ) through the guiding catheter. Changes of left ventricular end-diastolic diameter (LVEDd),LVEF and myocardium perfusion defects were assessed before and at (30 ±3) days and (90 ± 7) days after the procedure.Malignant cardiovascular events were also recorded.Results ( 1 ) One month after the procedure,LVEF in transplantation groups significantly increased compared to before procedure ( all P ＜0.05),and significant increase of LVEF was observed only in MSCs transplantation group compared to control group ( P ＜ 0.05 ).However,absolute changes of LVEDd and perfusion defects of myocardium were similar among and within groups (P ＞ 0.05 ).(2)Gomparing with before procedure and control group,LVEF in transplantation groups increased significantly in three months after the procedure (P ＜ 0.05 ),but there were no significant differences between transplantation groups ( P ＞ 0.05 ).LVEDd and myocardium perfusion defects in transplantation groups improved significantly compared with that of before procedure (P ＜0.05 ),while significant decrease of myocardium perfusion defects was only observed in patients treated with MSCs compared with control group at three months after procedure ( P ＜ 0.05 ). ( 3 ) There were no significant differences in major cardiovascular events between transplantation group and control during followup ( P ＞ 0.05).Conclusions Intracoronary bone marrow stem cells transplantation is safe and effective for DCM patients while the efficacy of MSCs and MNCs transplantation is comparable.

Objective:To study the expression of the Homeobox C6(HOXC6)gene in the homeobox family in PCa,its effect on the biological behavior of PCa cells and its action mechanism.Methods:Based on the studies of HOXC6 retrieved from the data-base of Gene Expression Profiling Interactive Analysis(GEPIA),we analyzed the expression of HOXC6 in PCa and the relationship of its expression level with the survival prognosis of the patients.We detected the expression of the HOXC6 protein in PCa tissues and cells by Western blot,stably interfered with the expression of the HOXC6 gene in human PCa DU145 and PC-3 cells and normal prosta-tic epithelial RWPE-1 cells using the siRNA plasmid,and determined the effects of HOXC6 on the proliferation,migration and inva-siveness of PCa cells by CCK8,plate cloning and scratch healing and Transwell invasion assays.Using the GEPIA database,we ana-lyzed the correlation of the Wnt tumor inhibitory factor-secreted frizzled-related protein 1(SFRP1)gene with HOXC6,and detected the expressions of HOXC6,SFRP1,Wnt and β-catenin in PC-3 cells after siRNA-HOXC6 transfection by Western blot.Results:The expression of HOXC6 was dramatically higher in the PCa than in the normal prostate tissue(P<0.01),and in the PCa cells than in the normal prostatic epithelial cells(P<0.01).Bioinformatics analysis indicated a lower survival rate of the PCa patients with a high than those with a low HOXC6 expression(P=0.011).The relative expression of the HOXC6 protein,absorbance value,number of clones formed and number of invaded cells were significantly lower in the siRNA group than in the negative controls(P<0.05).Ac-cording to the GEPIA database,highly expressed SFRP1 was associated with a good prognosis of PCa,and the protein expressions of Wnt and β-catenin were markedly increased while that of SFRP1 decreased in the PCa PC-3 cell line(P<0.05).The expressions of the Wnt and β-catenin proteins were decreased and that of SFRP1 increased significantly in the siRNA-HOXC6 transfection group com-pared with those in the siRNA negative control and PCa PC-3 groups(P<0.05).Conclusion:HOXC6 is highly expressed in PCa tissues and related to the proliferation,migration and invasiveness of PCa cells.HOXC6 promotes the growth of DU145 and PC-3 cells in PCa by inhibiting the SFRP1/Wnt/β-catenin signaling pathway,and may be a potential target for clinical treatment of PCa.
