BACKGROUND: As a new-type and effective restoration means of dentition defect and edentulous,implant denture is a restoration method most closely related to natural teeth,and is accepted by more and more patients.OBJECTIVE: To investigate the clinical effects of non-submerged dental implants with sandblasted and acid-etched surface preparation(Straumann implants system).METHODS: Patients who visited Oral Implantology Center of the Affiliated Hospital of Qingdao University Medical College from June 2007 to June 2009 were selected as study subjects.Systemic and local contraindications were excluded.A total of 124patients who had 218 Straumann implants implanted were followed up for 3 to 24 months.According to various patients' conditions,conventional approach,immediately implanted,GBR technique and flapless operation were adopted respectively.Clinical effects were evaluated with the Albrektsson's criteria.RESULTS AND CONCLUSION: There was no implant loosen,shedding or X-ray transmission in 218 implants.Both the survival rate and successful rate of implants were 100%.High degree of satisfaction from patients was achieved.Straumann implants system could be considered as a manageable and satisfactory non-submerged implant system.

ObjectiveTo summarize the application of pressure support ventilation (PSV) on cervical spinal cord injured patients with respiratory dysfunction.MethodSixteen patients were studied.Respiratory rate (RR),tidal volume (VT), minute ventilation (VE),peak inspiration pressure (PIP), dynamic lung conpliance (Cdyn), blood pH value, PaO2 and PaCO2 were measured under the different pressure levels of PSV. ResultAll parameters correlated with the level of PSV. Conclusion Appropriate PSV levels can make the respiratory parameters close to the reasonable level and respiratory functional status for the cervical cord injured patients with respiratory dysfunction.

ObjectiveTo observe the difference between pressure support ventilation(PSV) and synchronized intermittent mandatory ventilation(SIMV) in cervical spinal cord injury patients with respiratory failure.MethodsThe blood gas analysis,respiratory rate,heart rate,blood pressure and subjective feelings were observed in the same patient under different ventilation(PSV or SIMV).ResultsThere was no significant difference in blood pressure when patients underwent PSV and SIMV.Otherwise,There was significant difference in respiratory rate,heart rate,pH,PaO2,PaCO2 and subjective feelings when patients underwent PSV and SIMV,which showed that of PSV were better.ConclusionThe effect of PSV was better than that of SIMV on respiratory failure after cervical spinal cord injury.

Objective] The mechanism of astragalus polysaccharides treatment of asthma was discussed. [Methods]Through the domestic and foreign about traditional Chinese medicine monomer astragalus polysaccharide on IL-4, IL-10 and other cytokines and inflammatory infiltrates aspects such as the Th1/Th2 balance, smooth muscle actin and airway mucus in the airway remodeling and asthma related gene research literature summary. [Results] Improve airway inflammation astragalus polysaccharides from activation and inhibition EOS EOS infiltration reduction, regulating Th1/Th2 imbalance, so Th0 cells to Th1 cell differentiation, and inhibiting the release of inflammatory cytokines and other aspects, APS can reduce airway hyper-responsiveness mitigate aspects peribronchial infiltration of eosinophils and airway smooth muscle cells induced byα-SMA expression and other high alleviate airway remodeling. [Conclusion] The influence of astragalus polysaccharide on asthma gene research will lay the basis for study of the mechanism of treatment of asthma, monomer research provides new ideas for traditional Chinese medicine.

Objective To investigate the effect of different doses of dexmedetomidine on myocardial injury (in perioperative peri‐od) on cardiopulmonary bypass (CPB) in patients with rheumatic heart valve replacement surgery .Methods Patients undertook rheumatic heart valve replacement surgery with mitral stenosis were divided into three groups (n=20) in randomized and double‐blind method :control group (group C) ,dexmedetomidine 0 .3 μg/kg group (DEX1 group) ,dexmedetomidine 0 .6 μg/kg group (DEX2 group) .Central venous blood was drawn respectively before anesthesia induction (T0 ) ,2h after CPB (T1 ) ,24 h after CPB (T2 ) ,48 h after CPB (T3 ) ,72 h after CPB (T4 ) .Plasma muscle calcium protein I (cTnI) and creatine kinase (CreatineKinase MB , CK‐MB) were measured and mean arterial pressure and heart rate were recorded at each time point .Furthermore ,extubation time , ICU stay ,postoperative inotropic score 24 h after operation ,drainage 24 h after operation ,cardio auto‐resuscitation rates and ad‐verse cardiovascular events were recorded .Results Compared with T0 ,HR was significantly lower in the T1 time point in DEX2 group .Compared with group C ,HR ,plasma CK‐MB ,inotropic score 24 h after operation and cardiovascular adverse events was sig‐nificantly reduced in the T1 time points in DEX1 group (P<0 .05) ,but the heart auto‐resuscitation rate did not significantly im‐proved .HR at T1 ,plasma CK‐MB values at T1 and T2 ,and plasma cTnI values at T2 -T4 were significantly reduced ;the heart re‐suscitation significantly increased ,myocardial contraction power ratings 24 h after operation and the incidence of cardiovascular e‐vents was significantly lower in DEX2 group (P<0 .05) .The extubation time ,ICU stay time and drainage 24 h after operation did not change significantly in both groups .Conclusion Dexmedetomidine has a protective effect on perioperative myocardial injury in patients with rheumatic heart valve replacement surgery ,and the effect would be better when the dexmedetomidine was infused at 0 .6 μg · kg -1 · h-1 after a loading dose of 0 .6 μg/Kg continuously .

Objective To construct a new gene delivery system based on atelocollagen (ATE),and explore that modified aptamer (APT),and APT-ATE/miRNA (miRNA-15a and miRNA-16-1) were successfully synthesized to treat bone-metastatic prostatic cancers.Methods Flow cytometry (FCM) analysis was used to characterize APT-ATE complex.The diameter and zeta potential of complexes were measured by Zetasizer Nano-ZS9.The prostatic cancer (PCa) distribution experiments were used to explore its biological characteristics and targeting ability of PCa cells (PC3 and LNCaP).The inhibition of APT-ATE complex on LNCaP cell was determined with the cholecystokinin (CCK)-8 assay.Results FCM results demonstrated the successful synthesis of ATE-APT complex.The cellular uptake of vectors was concentration-dependent.The gene expression in vitro indicated that the modification of APT could increase the efficiency of gene expression and PCa targeting ability of ATE vectors to LNCaP [prostate specific membrane antigen (PSMA) over-expressing prostate cancer cells].The result of biodistribution showed that the bone uptake of APT-ATE was higher than ATE-APT.Conclusions APT-ATE/miRNA might be useful for preclinical and clinical studies on the treatment of bone-metastatic PCa.
