Objective:This work presents the therapeutic advantage of induction therapy in patients withⅢA-N2 non-small cell lung cancer (ⅢA-N2 NSCLC). Methods:ⅢA-N2 NSCLC patients with ipsilateral mediastinal lymph node metastasis (>1 cm as shown by CT scan) who were admitted in our hospital between January 2008 and July 2013 were retrospectively analyzed. The response rates and survival outcomes of patients were presented and the prognostic factors were analyzed. Results:The 3-and 5-year overall survival (OS) rates were 57.7%and 34.2%, respectively, and the 3-and 5-year disease-free survival (DFS) rates were 37.9%and 30.5%, respec-tively. No significant differences in OS and DFS were observed between R0 and R1 resections (P=0.118; P=0.369), between groups who received neo-adjuvant chemo-radiotherapy and chemotherapy (P=0.771; P=0.953), between cases with and without clinical re-sponse (P=0.865;P=0.862), and among groups of different histological subtypes (P=0.685;P=0.208). However, patients with standard lobectomy or pathological nodal downstaging exhibited better OS (P=0.023 and P=0.024, respectively) and DFS (P=0.036 and P=0.025, respectively) than those who had extensive resections or persistent N2. Univariate analysis predicted better OS and DFS for both standard lobectomy and pathological nodal donwstaging. In addition, Cox multivariate analysis revealed that only pathological nodal downstaging could be considered as a favorable prognostic factor for DFS, while non-smoking and standard lobectomy are the corre-sponding variables for OS. Conclusion:Neo-adjuvant therapy with platinum-based doublet is feasible and useful in tumor and patho-logical nodal downstaging, which potentially improved resectability and survival rates in patients withⅢA-N2 NSCLC. Performing lo-bectomy or pathological nodal downstaging following induction therapy improved the patients' survival rate.

Objective To evaluate the changes in the expression of DJ-1 protein during myocardial ischemia-reperfusion (I/R) in diabetic rats.Methods Fifty male Sprague-Dawley rats,weighing 220-280 g,were used in this study.Type 1 diabetes mellitus was induced by intraperitoneal streptozotocin 65 mg/kg and confirmed by fasting blood glucose > 16.7 mmol/L.Forty animals with type 1 diabetes mellitus were randomly divided into 3 groups:diabetes group (group D,n =10),diabetic sham operation group (group DS,n =15) and diabetic I/R group (group DIR,n =15).Another 10 non-diabetic rats in which citrate buffer 6 ml/kg was injected intraperitoneally were served as control group (group C).Myocardial I/R was produced by occlusion of the anterior descending branch of left coronary artery for 30 min followed by 120 min reperfusion in group I/R.At 120 min of reperfusion,5 rats were sacrificed and myocardial specimens were c(on)tained for determination of infarct size in groups DS and DIR,and 10 rats were sacrificed and myocardial specimens were obtained for microscopic examination and for determination of cell apoptosis,malondialdehyde (MDA) content,superoxide dismutase (SOD) activity and expression of DJ-1 and phosphatase and tensin homologue (PTEN) protein.Apoptotic index (AI) was calculated.Linear correlation between the expression of DJ-1 protein and MDA content,SOD activity,AI and expression of PTEN protein was analyzed.Results Compared with group DS,the myocardial infract size was significantly increased in group DIR (P < 0.05).Compared with group C,MDA content and AI were significantly increased,SOD activity was decreased,the expression of DJ-1 was down-regulated,and the expression of PTEN protein was up-regulated in groups D,DS and DIR (P < 0.05).Compared with groups D and DS,MDA content and AI were significantly increased,SOD activity was decreased,the expression of DJ-1 was down-regulated,and the expression of PTEN protein was up-regulated in group DIR (P < 0.05).There was no significant difference in the parameters mentioned above between groups D and DS (P > 0.05).There was linear correlation between the expression of DJ-1 protein and MDA content,SOD activity,AI and expression of PTEN protein and the correlation coefficients (r) were-0.734,0.593,-0.818,and-0.812 in turn.Conclusion Down-regulation of DJ-1 protein expression is involved in myocardial I/R injury in diabetic rats via decreasing anti-oxidative stress responses and upregulating PTEN protein expression.

Neurofibromatosis type 2 (NF2) is a dominantly inherited genetic condition. Bilateral vestibular schwannoma, which are benign tumors, composed of neoplastic Schwann cells that arise from the eighth cranial nerve, are the hallmark of NF2. Standard approaches for treatment of growing vestibular schwannoma include observation, surgical removal and radiation therapy. Molecular targeted therapies also present great prosperity in recent years. In this review, we summarize the latest progresses on the treatment of NF2-associated vestibular schwannoma.

?AIM:To study the changes of ocular surface in cataract patients with Meibomian gland dysfunction ( MGD) who treated with Meibomian gland massage before surgery.?METHODS: Totally 90 patients ( 93 eyes ) with cataract and MGD were randomly divided into two groups. Patients in experimental group were treated with hot compress and Meibomian gland massage every day before surgery, while the patients in the control group were not taken. Two groups of patients received phacoemulsification combined with intraocular lens implantation. Lid margin abnormalities, secretion characteristics, Schimer I test ( SⅠt) and tear film break-up time ( BUT ) were recorded and compared between two groups using slit lamp microscope inspection preoperatively and postoperatively 1wk.?RESULTS:In the control group, the postoperative score of eyelid margin and Meibomian gland secretion was increased significantly than preoperative, while the value of BUT and SⅠt was down significantly. Compared with control group, the postoperative score of eyelid margin shape and Meibomian gland secretion in the experimental group was decreased significantly, while the value of BUT and SIT improved significantly (P<0. 05).?CONCLUSION: Phacoemulsification can aggravate the Meibomian gland dysfunction and have some extent of effects on the ocular surface. Meibomian gland massage before surgery can significantly improve the function of Meibomian gland and the state of ocular surface in patients with MDG.

Objective:To observe the effect of calcitonin gene-related peptide (CGRP) on the expression of osteoprotegerin (OPG) and receptor activator of nuclear factor-kappaB ligand (RANKL) in osteoblast cells through an in vitro breast cancer cell and osteoblast cell co-culture system. Methods:The metastatic breast cancer MDA-MB-231 or MDA-MB-435 cells were co-cultured with osteoblast MG63 cells to establish an in vitro microenvironment of bone metastasis of breast cancer. After treated with CGRP(1?108 mol/L),OPG and RANKL mRNA and protein expressions in osteoblast MG63 cells were examined by RT-PCR and Western blotting. Results:Expression of RANKL in osteoblast MG63 cells was up-regulated at both mRNA and protein levels when osteoblast MG63 cells were co-cultured with breast cancer MDA-MB-231 or MDA-MB-435 cells,while those of OPG in osteoblast MG63 cells were both down-regulated (P

Objective To explore the autobiographical memory characteristics of chronic pain patients and its correlators.Methods Autobiographical memory,pain and emotion of 106 chronic pain patients and 106healthy controls were assessed with the Autobiographical Memory Test (AMT), the Short-form McGill Pain Questionnaire (SF-MPQ), the Pain Self-efficacy Questionaire (PSEQ), Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI).Results Compared to the control group, the clinical group had less specific memory (3.63 ± 1.53, 2.63 ± 1.68, F (1.416) = 7.233, P < 0.01 ) and more overgeneral memory (2.37 ± 1.53,3.37 ±1.68, F (1.416) =7.069, P<0.01 ),but the latency to response was not statistically significantly different between the groups.Duration of pain,frequence of pain and pain self-efficacy were the significant predictors of overgeneral memory,and the regression coefficients were significant (P<0.05 ) ,the multiple regression equation was statistically significant( R = 0.427, R2 = 0.183, F= 2.385, P< 0.05 ).Conclusion The autobiographical memory of chronic pain patients was overgeneralized because of the influence of duration, frequence and self-efficacy of pain.
