Objective To investigate the clinical features and the correlated reason of upper gastrointestinal bleeding (UGIB) induced by non-steroidal anti-inflammatory drugs (NSAIDs). Methods Five hundred and twenty-eight patients were divided into two groups according to consumption of NSAIDs in the week previous to the onset of bleeding, 116 cases were in NSAIDs group and 412 cases were in non-NSAIDs group. The clinical data was analysed and compared between two groups. Results There was no significant difference in sex, smoking history, and ulcer history between two groups (P> 0.05). The average age was (57.4 ± 12.1) years old and the infection of Hp was 65.5% (76/116) in NSAIDs group, and they were higher than those in non-NSA1Ds group [(44.6 ± 11.9) years old and 25.0% (103/412)](P < 0.01). More gastric ulcer and complex ulcer was seen in NSAIDs group (P <0.01 or <0.05). Conclusion Recognition about the clinical characteristics of NSAIDs relevance UGIB should be strengthened, and side effect of NSAIDs should be reduced as far as possible.

Objective:To culture canine dental pulp stem cells(cDPSCs)in vitro.Methods:Canine pulp cells were isolated and cultured by enzyme digestion and explanted tissue culture respectively.Cell morphology was observed under phase-contrast micro-scope.The clone forming unit(CFU)of the cells was examined by plate clone formation assay.Cell markers and protein-expression were examined by flow cytometry(FC)and immunofluorescence.Odontogenic and adipogenic potential were evaluated by alizarin red staining and oil red O staining.Results:Short spindle fibroblast-like and steadily growing cells were obtained by both methods.The clone assay showed that CFU was 1 5.1 7% ±2.79%.FC observasion showed that the CD90,STRO-1 and CD24 positive cells were 24.43% ±7.1 0%,20.67% ±1 .42% and 2.03% ±0.06% respectively,but CD34 was negative.Immunofluorescence analysis showed positive expression of Nestin,Vimentin,weak expression of ALP and negative expression of DSP of the cells.Differentiation ex-periment confirmed the odontogenic and adipogenic differentiation potential of the cells.Conclusion:cDPSCs can be cultured in vitro.

This article is based on the searching from the United States Library of Congress Web Search science 2005 for the literature on the birth femoral fractures,reviewing its incidence,pathogenesis and treatment of such fractures of the latest developments,for the purpose of the provision of orthopedic and obstetric physician reference.Literature showed that neonatal birth femoral fractures might occur whether deli-veries were through the birth canal or by cesarean section.Whenever faced with fetal asphyxia,intracranial hemorrhage,such as critical state,it is critical to save the life of fetal babies,regardless of treatment.The prognosis of neonatal femoral shaft fractures is normally good without deformity left.

Objective To analyze the cause of delayed hemorrhage after minimally invasive percu- taneous nephrolithotomy(MPCNL),and to summarize the experience in the interventional treatment of severe bleeding after MPCNL by superselective arteriolar embolization.Methods The clinical data of 3812 cases of MPCNL from June 1998 to July 2004 were reviewed.Of them,12 patients(11 men and 1 woman;mean age,45 years)who developed severe hemorrhage after MPCNL were identified.The cause of hemorrhage and the treatment results were analyzed.Results The rate of delayed hemorrhage after MPCNL was 0.31% (12/3812).The mean time to onset of severe bleeding was 10 d after MPCNL.Renal arteriography was per- formed in all 12 patients,showing 5 arteriovenous fistulas and 7 false aneurysms.Superselective arteriolar em- bolization for hemostasis was performed in all 12 cases.All these vascular abnormalities were successfully treated by superselective embolization.Follow-up showed that the hematuria disappeared and renal function recovered well.Conclusions Severe hemorrhage following MPCNL is a rare complication,the incidence of which is significantly lower than that of conventional PCNL.The cause is mainly the arteriolar injury of re- nal puncture passage.Superselective embolization provides effective control of bleeding and currently consti- tutes the treatment of choice based on our experience.

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.
