Objective To observe and evaluate the clinical effect of Dentium planting system by once procedure.Methods A total of 45 patients who had 55 Dentium implants implanted were followed up for one year. Permanent restorations were finished 12 weeks after once procedure.Clinical effects were evaluated through clinical and imaging examination.Results Through the 55 Dentium implants of 45 patients,the success rate was 100%.All patients were satisfied with aesthetics and occlusal function.Conclusion Dentium implant completed by once procedure is safe and reliable with once procedure on clinical application.Both the survival rate and successful rate of implants were 100%.High degree of satisfaction from patients was achieved.Both bone tissue and soft tissue are well preserved.This system can obviously reduce bone resorption and improve aesthetic effect.

Objective It describes procedures for designing an analyzing a method comparison experiment for serum albumin(ALB) assay and determining the relative bias between two methods using split patient samples.Method According to the procedure described by the NCCL approved guideline: method comparison and bias estimation using patient samples; 40 patient samples were analyzed in 5 operating days, analyze each patient sample in duplicate using both BCG and BCP method. The duplicates were assessed for each method within the same run. The coefficient of correlation was calculated as well as the bia between the methods.Results In the patient′s serum sample, the bias between BCG and BCP methods were 1.8% at 50g/L or 5.5% at 40 g/L or 11.6% at 30 g/L for albumin. In the commercial quality control serum products, the bias between the two methods varied up to 36%.Conclusion In determination of the patient′s ALB, the bias between BCG and BCP goes up when the concentration of ALB is decreased. But the bias between the two methods varies up to 36% when the quality control serum is determined.

Objective The aim of this study was to investigate the radiation dose caused by 18 F-fluorodeoxyglucose (FDG) in PET/CT examination and to optimize the concerned radiation protection. Methods Thirty patients from our conventional PET/CT examination were simple randomly selected, and they all underwent whole body PET/CT imaging. The radioactive dose of injected 18F-FDG was recorded. The internal radiation dose was calculated and the external radiation dose from patients was measured with the 451P-DE-SI ion chamber survey meter. The staff's dose was recorded with thermoluminescent detector (TLD). All dosimetry data were processed and analyzed statistically with Excel 2003. Results The injected radioactive dose of 18F-FDG was (432.9±51.8) MBq, and effective dose equivalent received per patient was (8.23±0.99) roSy. The correlation coefficient (r) of the dose equivalent rate and distance was-0.994 by power function curve fitting, and that of dose equivalent rate and time was - 0.988 by exponential curve fitting. The staff's dose was lower than the annual dose limit. Conclusions The patient's internal radiation dose caused by 18F-FDG in PET/CT examination is low, nonetheless, the clinician should always consider optimizing and minimizing the necessary radiation received by the patients. The patients having been injected with 18F-FDG should stay in one place to decrease their radiation to the public. From the medical point of view in optimizing radiation exposure, there may still be a potential to lower the injected 18F-FDG activity.

Objective To investigate clinicopathologic characteristics of obsolete Bennett fractures and their surgical treatment and prognosis. Methods From August 2008 to April 2010,13 patients with obsolete Bennett fracture were admitted to our department.They were 12 men and one woman,with an average age of 34.3 years (from 17 to 42 years).They had a fracture history of over 4 weeks to as long as 12 weeks (average,7.9 weeks).In all patients,after X-ray examinations,the radio-dorsal ligament complex of the first carpometacarpal joint was properly released,fracture gaps were cleared up,fracture fragments were anatomically reduced and fixed with a Kirschner wire,and at last the first metacarpal joint was fixed with the Kirschner wire crossing the joint Postoperatively all patients were immobilized with cast plaster for 4 weeks before the Kirschner wires acrross the joint were removed.Gradual rehabilitation was conducted.The X-rays were taken every month. Results The patients were followed for 6 to 24 months(average,14 months).The fractures healed in all the patients,with an average healing time of 3 months.No dislocation of the joints occurred.Injury to articular cartilage of the trapezium bone occurred in one patient,and no apparent pain was experienced in the other 12 patients.According to the Total Active Motion assessment,the thumb function was rated as excellent in 9 cases,good in 2,moderate in one and poor in one,with a good to excellent rate of 84.6％.Conclusions In obsolete Bennett fractures,the radio-dorsal ligament complex of the first carpometacarpal joint will have cicatricial contracture,preventing reduction of the fragments of the radio-dorsal joint.Therefore it is important to properly release the radio-dorsal ligament complex to achieve anatomical reduction of the radio-dorsal joint.An injury history of over 3 months and complicated injury to the trapezium bone cartilage may be significant factors affecting the prognosis of obsolete Bennett factures.

It has been 4 years since Natural Health Products Regulations(NHPRs)was enforced by Health Canada in January of 2004.In the past time,how will it affect the marketed Traditional Chinese Medicines(TCM) in Canadian market? Recently,The two TCM products Carditionic Pill (Fufang Danshen Diwan)and Chaihu Pill from Tasly have been newly certificated by Health Canada recently.Taking them as examples,this article introduces the current status.opportunities and challenges for the regulation of TCM in Canada.and suggests that the domestic TCM corporations push the product registration as soon as possible.

Ramie and kenaf were traditional fiber crops in China, but their stalk after decorticating has not been used effectively. The stalk contains a lot of cellulose, and can therefore be used for the production of bioethanol. We studied the effects of different chemical pretreatment on enzymatic digestibility of ramie stalk and kenaf stalk. Ramie and kenaf stalks pretreated with alkali were chosen to produce ethanol using quasi-simultaneous saccharification and fermentation (Q-SSF) process. The results show that for the stalks pretreated with 4% NaOH and 0.02% anthraquinone-2-sulfonic acid sodium salt (AQSS) as catalyzer at 170 degrees C for 1 h, the ethanol concentration could reach 51 g/L after fermentation for 168 h at 18% of solid substrate concentration. By fed-batch to 20% of solid substrate concentration, the ethanol concentration could reach 63 g/L, 77% and 79% of the cellulose conversion could get for ramie stalk and kenaf stalk, respectively. For kenaf stalk pretreated with 5.2% NaHSO3 and 0.2% H2SO4 at 170 degrees C for 1 h, the ethanol concentration and cellulose conversion could reach to 65 g/L and 72%, respectively.
