Objective:To explore the clinical diagnosis and treatment methods for nasal septum malignancies. Methods:A retrospective study of seven cases of primary nasal septum malignancy was conducted. These cases were treated at the Tianjin First Central Hospital between February 1993 and October 2009. Results:Among the seven cases, one was reported malignant lymphoma, which underwent chemotherapy and radiation therapy;the other six malignant tumors included three cases of adenoid cystic carcinoma, one malignant melanoma, one chondrosarcoma, and one papilloma. Patients were treated by nasal endoscopy, external approach, lip midline incision, overturned facial surgery, chemotherapy, and radiation. During follow-up, which lasted for 2 years to 16 years from time of surgery, two fatalities resulting from recurrence or metastasis were recorded. One of these fatalities occurred after 2 years, and the other was recorded at 3 years and 4 months after surgery. Four patients survived without recurrence. Conclusion:The key treatment for nasal septum malignancies was one-time radical resection. Combined postoperative treatment and follow-up should be conducted.

Objective To investigate the effects of virtual reality prism adaptation on visuospatial neglect in stroke patients.Methods Thirty stroke patients with visuospatial neglect were studied.The subjects were divided into atreatment group and a control group.The subjects in the treatment group were treated with virtual reality prism adaptation and routine rehabilitation interventions for 2 weeks,while those in the control group were treated with routine rehabilitation interventions only.All the patients performed a battery of spatial attention tests including line bisection,letter cancellation,clock drawing and the Attention Network Test at the beginning and after 2 weeks of treatment.Results The virtual reality prism adaptation training had significant positive effects on all the measures of visuospatial neglect.Pair-wise comparisons confirmed significant differences between the treatment and control groups after 2 weeks of treatment with regard to all of the measures.Conclusions Virtual reality prism adaptation treatzment combined with routine rehabilitation can be more effective than conventional measures alone in improving the visuospatial performance of stroke survivors.

Objective To investigate the effect of smoking and smoking cessation on the phosphorylation of IKK-β in type 2 diabetic rats. Methods Forty-two six-week-old Wistar rats were randomly divided into 4 groups: normal control(NC, n =7), diabetes control (DC, n =7), diabetes with smoking (DS, n = 14) and diabetes with smoking cessation(SC, n = 14). Rats in DS and SC groups were further assigned randomly into 8w and 12w subgroups. DS group was given passive smoking twice a day for 8 or 12 weeks, while SC group ceased passive smoking for 4 weeks after 8 or 12 weeks of smoking . Western blot method was used to detect the level of IKK-13 phosphorylation in skeletal muscle. Results Compared with the NC group,the phosphorylation of IKK-β protein in DC group was increased (0. 16±0. 05 vs 0. 30±0. 08, P < 0. 01). There was an increasing trend with the phosphorylation level of IKK-β in the DS (8w) subgroup, but there was no statistical difference between the DC group and SC(8w) subgroup (0. 40±0. 09 vs 0. 30±0. 08,0. 36±0. 10, P >0. 05). The phosphorylation level of IKK-β in DS(12w) group increased obviously, being significantly higher than that in the DC group and SC (12w) subgroup(0. 74 ± 0. 11 vs 0.30±0.08,0.35±0.07,P < 0.01). Conclusion With the prolongation of smoking duration, the phosphorylation of IKK-β in type 2 diabetic rats increased. After smoking cessation, the phosphorylation of IKK-β decreased. The phosphorylation of IKK-β may be involved in the mechanism by which smoking causes type 2 diabetes.

Objective To explore the role of left frontoparietal pathway in controlling spatial attentional function. Methods 60 healthy, right-handed humans (30 males and 30 females) aged 18~22 years were recruited. They were divided into frontal group (n=30) and parietal group (n=30) in accordance with sex for either the left dorsolateral prefrontal cortex or the left posterior parietal cortex stimuli study, respectively. They were measured with the Attention Network Test following the continuous theta burst stimulation to the left frontoparietal pathway. Results During the Attention Network Test, the efficiencies of alerting network improved in participants after both the left dorsolateral prefrontal cortex and left posterior parietal cortex stimuli. However, the efficiency of orienting network was deficit after the left dorsolateral prefrontal cortex stimuli. Conclusion Inhibition of the left frontoparietal pathway may improve the alerting function of spatial attention network.

Pulmonary surfactant is a lipid-protein complex that lines and stabilizes the respiratory interface in the alveoli, allowing for gas exchange during the breathing cycle. ATP-binding Cassette transporters A3, is a lipid transporter in the limiting membrane of lamellar bodies in alveolar type Ⅱ cells that plays a critical role in the regulation of pulmonary surfactant homeostasis. Mutations in the ABCA3 gene cause respiratory distress syndrome in new-born and childhood interstitial lung disease. An updated view on expression of ABCA3 gene and ABCA3 mutation associated with neonatal respiratory distress syndrome,or childhood interstitial lung disease was reviewed.

Objective To investigate the characteristics of blood glucose fluctuation of continuous ambulatory peritoneal dialysis (CAPD) patients with end stage diabetic nephropathy(ESDN) attaining glycated hemoglobin standard. Methods The study recruited 17 patients with type 2 diabetes attaining glycated hemoglobin standard, and used continuous glucose monitoring system (CGMS) to monitor glycemic variation for 72 h. General information was collected and biochemical indexes were determined. Results The mean amplitude glycemic excur-sions (MAGE), standard deviation ,mean blood glucose levels, maximum of blood sugar, and the proportion of greater than 13.9 mmol/L in peritoneal dialysis patients were (8.36 ± 4.44) mmol/L, (3.38±1.08) mmol/L, (9.88±1.92) mmol/L, (17.95±13.11)%, which were significantly higher than those in normal. The mean amplitude glycemic excur-sions (MAGE), standard deviation ,mean blood glucose levels, maximum of blood sugar, and the proportion of greater than 13. 9 mmol/L in daytime were (8.25± 3.71) mmol/L, (2.83±0.89) mmol/L, (11.32±2.54) mmol/L, (16.61±3.86) mmol/L, (28.45±19.56)%, which were significantly higher than those in nighttime: (4.20±2.67) mmol/L, (1.34±0.89) mmol/L, (7.02±1.92) mmol/L, (9.61±2.77) mmol/L, (5.31±1.28)%, all P<0.05. The minimum and the proportion of less than 3.9 mmol/L between the two groups had no significant difference ( P>0.05). Besides, biochemical glycosylated hemoglobin was less than the calculated from CGMS: (5.88± 0.73)%vs. (7.85±1.20)%, t=4.76, P<0.01. Conclusions Peritoneal dialysis patients with ESDN have an increased glycemic fluctuation and a unsatisfied glycemic control, which is worse in daytime. Glycosylated hemoglobin is undervalued. Glycosylated hemoglobin should not be simply used on hemodialysis patients with ESDN to evaluate whether they have a good glycemic control. CGMS can better describe their blood sugar condition.

Objective:To investigate the effect of metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) in modulat-ing the effects of oral squamous cell carcinoma (OSCC) invasion. Methods:Real-time polymerase chain reaction was employed to de-tect the expression of MALAT1 in samples of OSCC post-radical resection, normal oral mucosa samples, and oral squamous cell lines. MALAT1-siRNA was transfected into TSCCa human tongue squamous cell carcinoma cell lines. Cell proliferation was determined by methyl-thiazolyl-tetrazolium reduction assay. Cell migration and invasive ability were evaluated by scratch test and transwell assay. The expression of proteins that regulated invasion and apoptosis were examined using Western blot assay. Immunofluorescence assay was used to detect changes in epithelial-mesenchymal transition (EMT)-associated proteins in the cells. Tumor-bearing nude mouse models were established by subcutaneous implantation of TSCCa cells. Immunohistochemistry was used to detect up-regulation of proliferating cell nuclear antigen (PCNA) and matrix metalloproteinase-2/9 (MMP-2/9). Results:MALAT1 expression was significantly higher in OSCC than in normal tissues (P<0.05). MALAT1 expression was inhibited by transfecting MALAT1-siRNA. After MALAT1 expres-sion was down-regulated in TSCCa cells, proliferation was inhibited and invasion was attenuated, showing significant differences com-pared with the cells transfected with scrambled siRNA and control cells (P<0.05). Expression of N-cadherin and MMP-2/9 were down-regulated in the cells after MALAT1 was knocked down. Tumor growth was significantly slower in the MALAT1-siRNA group than in the control groups. IHC indicated that PCNA and MMP-2/9 expression of tumor tissues were significantly inhibited in MALAT1-siR-NA group. Conclusion:MALAT1 is over-expressed in human OSCC. MALAT1 reduction can inhibit the proliferation and invasion of OSCC cells. Furthermore, MALAT1 may promote OSCC invasion and metastasis by modulating EMT.

ObjectiveTo investigated the effect of post-operative primary site radiotherapy on stage Ⅳ neuroblastoma.Methods From Jan 2003 to Dem 2010,47 newly diagnosed stage Ⅳ neuroblastoma treated in Sun Yet-sen university cancer center.The treatment protocol for these patients were induction chemotherapy 4- 12 cycles,followed by surgery if possible,then 4-6 cycles consolidation chemotherapy and/or primary site radiotherapy and maintenance immunotherapy.The median age was 4 years old,the median induction chemotherapy cycles was 5.37 patients received resection of the primary tumor (total resection and nearly gross resection).24 out of 37 received primary site radiotherapy.ResultsThe followup rate was 89％.34 cases were followed up more than 36 months.For patients with or without postoperative primary site radiotherapy,the local recurrence rate were 13％ ( 3/24 ) and 54％ ( 7/13 ),respectively ( P =0.016),the 3-year local control rate were 84％ and 47％,respectively ( χ2 =7.95,P =0.005 ).The 3-year overall survival rate were 56％ and 28％,respectively ( χ2 =5.44,P =0.020 ). There was no severe radiation side effect. Conclusions This study indicated that postoperative primary site after induction chemotherapy and surgery could reduce the local recurrence rate and possibly improve the overall survival rate of stage Ⅳ neuroblastoma.
