ObjectiveTo investigate the features of pulmonary function and influencing factors in patients with cervical spinal cord injury (SCI).MethodsThe pulmonary function data of 48 patients with cervical SCI were analyzed. The correlations between the percent predicted values of vital capacity (VC), maximal voluntary ventilation (MVV), forced expiratory volume of 1st second (FEV1) and V75 (expressed as VC%, MVV%, FEV1%, V75%) and ASIA motor/sensory scores were analyzed. Then, four multiple linear regressions were run to use VC, MVV, FEV1, V75 as an independent variable respectively.ResultsThe percent predicted values of the pulmonary function (VC%, MVV%, FEV1%, V75%) in patients with cervical SCI obviously decreased, which suggested that these patients had a restrictive ventilation disorder. There were significant positive correlations between VC%、FEV1%、V75% and ASIA motor scores (by bivariate correlation tests), no significant correlations between any of pulmonary function parameters and the ASIA sensory scores. Of four linear regression models, the height showed as a protecting factor in 3 linear regression models and weight did in the other one respectively. Of parameters associated with SCI, just ASIA motor scores showed as a protecting factor in 3 linear regression models, no sensory scores or duration appeared in any linear regression models.ConclusionBesides the height and weight, the ASIA motor score is a main factor influencing the pulmonary function.

Objective To explore the protective effect of Salvianolic acid B on isolated lung in rats.Method Twenty-four SD rats were randomly divided into 2 groups:control group and experimental group (n =12 each).The isolated lung in control group was perfused with raffinose-low potassium dextran (R-LPD),and that in experimental group was perfused with R-LPD and 800 mg/L of Salvianolic acid B.The model of isolated lung was established in all these rats.Wet/dry weight ratio (W/D),myeloperoxidase (MPO),malondialdehyde (MDA) and superoxide dismutase (SOD) were measured,and the pulmonary structures were observed by HE staining at different preservative periods of 6,9,12 and 24 h after infusion.Result Intragroup comparison was made in both groups:all parameters had no statistically significant difference before 12 h.However,W/D,MPO,MDA,and SOD at 24 h were higher than those at 12 h (P＜0.01).The result of interclass comparison showed that after 6,9 and 12 h preservation,all parameters of these two groups showed no significant difference.However,W/D,MDA and MPO were lower,and SOD was higher after 24 h preservation in control group (P＜0.05).Moreover,before 12 h preservation,the two groups did not show inflammatory injury,only manifested slight inflammatory reaction histologically.Destructive pulmonary structure,alveolar interstitial edema and inflammatory damage were seen more clearly in control group than in experimental group.Conclusion The perfusion with Salvianolic acid B had no apparent superiority before 12 h.However,after 12 h,it could ensure the quality and prolong the preservation time of the donor lungs more effectively.Salvianolic acid B might play an important role in donor lungs protection.

The progressive attrition of teeth is a normal process by aging. However, excessive tooth wear with decreased vertical dimension of occlusion and collapse of occlusal plane may cause pathologic pulpal condition, occlusal disharmony, functional disorders and esthetic problems. The change of vertical dimension is required in case that there is no sufficient clearance for restoration or in case that the occlusal relationship is modified. For gaining the vertical dimension, a careful diagnosis is essential prior to starting the restoration treatment. After evaluating adaptation of neuromuscular system of patient during provisional phase, the final restorations can be fabricated. In this case, a 78 year old male with severely worn down dentition was treated. To improve the esthetic appearance and to achieve the ideal occlusal relationship, the full mouth rehabilitation with minimal increase of vertical dimension is planned and diagnostic wax-up was performed at the increased vertical dimension. After evaluation of provisional restorations for 12 weeks, final restorations were fabricated and routine clinical assessments were made. After 1 year, the restorations with newly established occlusal scheme are well maintained without significant complications and esthetically and functionally satisfactory results were obtained.

PURPOSE: Asthma is an inflammatory disease of the airways that is induced by Th2 cytokines and inhibited by Th1 cytokines. Oligodeoxynucleotides containing a CpG motif(CpG ODN), as potent inducers of Th1 immunity, are considered promising candidates for immune modulation in asthma. In this study we wanted to investigate the effect of CpG ODN on eosinophilia and cytokines of BALF in a mouse model established airway inflammation and the optimal route(systemic vs mucosal) of CpG ODN. We examined the difference of immunologic responses between CpG ODN and corticosteroids. METHODS: Female BALB/c mice, induced pulmonary allergic inflammation, were treated intranasally or intraperitoneally with CpG ODN and Dexamethasone. Allergen-specific antibody responses, cytokines(IL-4, IL-5, IL-12), and eosinophilic inflammation of the airways were investigated on BALF and splenocyte. RESULTS: CpG ODN effectively induced IL-12 and inhibited IL-4 and IL-5 as well as eosinophilic inflammation when CpG ODN was administered intranasally or intraperitoneally with allergen challenge. Therapy with corticosteroides, while effective inhibiting IL-5 generation, did not induced IL-12 in BALF. CONCLUSION: Systemic or mucosal administration of CpG ODN effectively stimulated the production of Th1 cytokines and suppressed eosinophilic airway inflammation in contrast of corticosteroids and control ODN. Thus, CpG ODN vaccination is a potentially useful approach for immunomodulation of established airway inflammation in a mouse model of asthma.
