Objective To evaluate the expression of Survivin,PTEN in tongue squamous cell carcinoma (TSCC) and the correlation with vascular endothelial growth factor (VEGF) and its clinical significance.Methods The expression of Survivin,PTEN and VEGF of 72 TSCC samples and 15 normal tongue mucosa (NTM) samples were detected by immunohistochemical method.Results The positive expression rate of Survivin,PTEN and VEGF in TSCC were 66.7％(48/72),61.1％(44/72),70.8％(51/72)respectively,while the positive expression rate in NTM were 0,100.0％ (15/15),0.There were statistical significance between the rate in TSCC and NTM respectively (P ＜0.01 ).The expression of Survivin and VEGF in TSCC were positively correlated with TNM stage,histological grade and lymph node metastasis (P＜ 0.05 or ＜ 0.01 ),while the expression of PTEN had negative correlation with them (P＜ 0.05 or ＜ 0.01 ).The expression of Survivin was positively correlated with VEGF expression in TSCC (r=0.6482,P＜0.01),while the expression of PTEN was negatively correleted with VEGF expression (r =-0.4027,P ＜0.01).Conclusions The expression of Survivin and PTEN in TSCC are associated with tumor occurrence and development closely,and are both significantly correlated with VEGF.Joint detection of Survivin,PTEN and VEGF have important reference value in clinical diagnosis,metastasis and prognosis of TSCC.

Objective To investigate the characteristics of stem cells marked with bromode oxyuridine (Brdu) and telomerase reverse transcriptase (TERT) in lung tissue, as well as its effects on pulmonary development and injury-repair. Methods A model of hyperoxia in neonatal rats was established by exposed to 95% O2 for 7 days. Before executing rats, Brdu was injected peritoneally, then Brdu and TERT positive cells were detected by immunohistochemistry. Results (1)The positive staining cells of Brdu with large nuclear located in septa and submucose of series bronchia, scattering in epithelium of bronchia, and the number of positive cells were less. The positive staining cells of TERT located in the septa and alveolar walls of peripulmonary tissue and the number of which was less than that of Brdu. (2)The positive cells of SPC located in septa and alveolar walls. Staining with Brdu and TERT, small number of positive cells was observed. (3) In hyperoxia and normal oxygen group, integral of expression of Brdu, TRET and SPC had no differences. But integral of expression of Brdu in whatever hyperoxia (1. 61?0. 83) or normal oxygen group (1. 43?0. 85) were higher than TRET and SPC (P

Objective To study the effect of dexamethasone on KGF expression in lungs of neonatal rats after hyperoxic exposure. Methods A randomized controlled study was designed in 48 Sprague-Dawley neonatal rats of 3 days old and divided into hyperoxia group, hyperoxia + dexamethasone and control groups for 7days. Histologic examination of the lung tissues were studied and radical alveoli count (RAC) were determined after HE staining. KGF expression was detected by immunohistochemistry. Results (1)The lungs of the rats in the hyperoxia group showed thinner walls of alveoli, simple alveolar structure, fewer and larger alveoli, expanded and shrinked alveoli. While those rats in the dexamethasone group showed more severe changes and some destroyed septa and walls of alveoli which lead to structure turbulence of the pulmonary tissue. The RAC in the hyperoxia and dexamethasone group was siginificanly lower than that in the control group (9.50?1.05, 10.03?3.26 vs 13.00?1.79, P

BACKGROUND:Common therapies for damage to the central tendon of finger extensor tendon include Matev, Carrol, Fowler methods as wel as residual central tendon flipping repair, but the therapeutic effects are no satisfied with bloated appearance, tendon adhesions, limited joint function. OBJECTIVE:To investigate the clinical effects of dorsal longitudinal driling and segmental tendon graft to repair old central tendon injury. METHODS:Eighty patients with old central tendon injury were randomized into treatment group and control group, with 40 cases in each group. In the treatment group, dorsal longitudinal driling and segmental tendon transplantation were given; while in the control group, Carrol, Matev, Fowler methods were chosen according to the individual conditions. Then, the therapeutic outcomes were compared between two groups. RESULTS AND CONCLUSION:The excelent and good rate was 85% in the treatment group and 65% in the control group, and there was a significant difference between the two groups (P < 0.05). Results from Valpar Component Work Samples showed that the number of cases adapting to the original work was 30 cases (75%) in the treatment group and 16 (40%) in the control group, and there was also a significant difference between the two groups (P < 0.05). The degree of proximal interphalangeal joint flexion was increased gradualy in the two groups at admission, at 15 days after hospitalization, at 1 day before discharge and at 4 months after discharge, and meanwhile, the degree of proximal interphalangeal joint dorsiflexion was reduced gradualy (P < 0.05). There were significant differences in the degree of proximal interphalangeal joint flexion and degree of proximal interphalangeal joint dorsiflexion between the two groups at 15 days after hospitalization, 1 day before discharge, and 4 months after discharge (P < 0.05). These findings indicate that the dorsal longitudinal driling and segmental tendon graft for repair of old central tendon injury can play an effective role in the recovery of articular flexion and extension function.
