Emergency departments of hospitals are exposed to risks of patient complaints and disputes, and the emergency department of a stomatology hospital is no exception. Medical disputes at the emergency department of Peking University Stomatology Hospital, as registered at the department of medical affairs of the hospital in the past ten years, are analyzed with statistical processing. The results are used in studying characteristics of medical disputes frequently found in stomatology emergency cases, for references and recommendations on prevention and avoidance of such disputes in future.

It is an urgent task to transform scientific research achievements on traditional Chinese medicine (TCM) into standard for the science and technology workers of TCM. The transformation not only improves the level of TCM standard, but also promotes the scientific research achievement on TCM into productivity. The Medium and Long-Term Strategic Development Plan for TCM Standardization issued by the State Administration of TCM of the People's Republic of China put forward reinforcement of study on method for transformation of TCM scientific research achievement into standard. Thus, this paper presented seven steps for the transformation on the basis of the TCM Standardization Regulation (trial) in order to provide some references.

ObjectiveTo evaluate and compare the efficacy and adverse effects of recombinant human tumor necrosis factor receptor Ⅱ : IgG Fc protein for injection (etanercept) and methotrexate ( MTX )regimens for rheumatoid arthritis (RA). MethodsForty-six patients were randomly divided into two groups by stratified sampling method:etanercept group,22 patients were treated with 12.5 mg of etanercept,twice times per week by subcutaneous injection;and MTX group,24 patients were treated with 5-10 mg of MTX,once per week by oral administration. The course of treatment lasted 24 weeks in both groups, so as to observe their ACR20, ACR50, ACR70 and adverse effects of the drugs. ResultsAfter treated for 24 weeks,ACR50,ACR70 respectively achieved 54.5％ (12/22),31.8％ (7/22) in etanercept group,which were significantly higher than those in MTX group[16.7％(4/24),4.2％( 1/24)]. The total efficacy was 86.4％ (19/22) in etanercept group, 20.8％ (5/24) in MTX group, the difference between the two groups was significant (P ＜ 0.05 ). The incidence of adverse effects was not significant between the two groups [22.7％(5/22) vs. 50.0％ (12/24)](P ＞ 0.05). ConclusionEtanercept has a good efficacy and safety for the treatment of active RA.

Objective To investigate the effect of antisense inhibitor of telomerase on growth of tumor cells.Methods:Phosphorothioate antisense oligonucleotides (PS-ASON) with sequence TAGGGTTAGACAA which can recognize the RNA template region of telomerase and PS-random primer with 13-nucleotides were incubated with RCZ cell line derived from renal cell carcinoma (RCC).The number of cells was counted from 1 to 43 days,doubling time was calculated and inhibiting rate was determined by MTT method.Results ASON group reduced the number of cells (P<0.01), lengthened doubling time (P<0.005),and elevated the inhibiting rate (P<0.01) compared with random primer control and empty control.The efficacy depended on the dose of ASON (P<0.05) and it was of sequence-selective specificity.Conclusion The ASON targeted to the RNA template has an inhibition effect on the growth of RCZ cell and may have potential significance in tumor therapy.

Objective To explore the influence of salinomycin in the growth, apoptosis and invasion of human bladder cancer 5637 cells,and to clarify its possible mechanism.Methods The human bladder cancer 5637 cells cultured invitro at logarithmic growth phase were divided into control group and different doses of salinomycin(15, 30 and 60μmol·L-1 )groups.The inhibitory rate of the growth of 5637 cells in various groups was measured by MTT assay. Flow cytometry was used to detect the apoptotic rates of 5637 cells in various groups. The invasiveness of 5637 cells was tested by Matrigel Invasion Assay.The expression levels ofβ-catenin protein in 5637 cells in various groups were determined by Western blotting method. Results Compared with control group,the inhibitory rates of growth of human bladder cancer 5637 cells in different doses of salinomycin groups were increased significantly(P<0.05);the apoptotic rates were increased(P<0.05).the number of cells passed the Matrigel was decreased(P<0.05),and the expression level ofβ-catenin protein was decreased (P<0.05).Compared with low dose of salinomycin group,the inhibitory rate of growth of 5637 cells in high dose of salinomycin group was increased(P<0.05);the apoptotic rate was increased(P<0.05),the number of cells passed the Matrigel was decreased (P < 0.05 ), and the expression levels of β-catenin protein was decreased (P<0.05). Conclusion Salinomycin can inhibit the growth of 5637 cells significantly,increase the apoptosis,and decrease the cell invasion;the inhibitory effect may act by inhibiting the Wnt/β-catenin pathway.

OBJECTIVE: To establish a RP-HPLC method for the determination of the content of hesperidin in Yangweishu tablets.METHODS: The samples were separated on octadecyl silane bonded gel silica column(150 mm?4.6 mm,5 ?m) with the mobile phase consisted of methanol-7% acetic acid solution(32∶68) under a detection wavelength of 283nm.RESULTS: The linear range of hesperidin was 49.6～892.8 ng(r=0.999 9) with an average recovery rate of 99.02%(RSD=0.45%,n=9).CONCLUSION:The method is simple,accurate,reproducible and applicable for the quality control of Yangweishu tablets.

Objective To observe the effect of the different bore diameter membranes on technological parameters of Radix Polygoni Multiflori Granula and to optimize the process of membrane filtration.Methods Three different membranes were tested under different parameters of operation to observe the changes in membrane flux and the content of effective components by Radix Polygoni Multiflori Granula.Results The membrane(50 nm)had the great flux,the transfering rate of stilbene glucoside was the highest;The optimum conditions:the operation differential pressure was 0.8-1.2 MPa;The operation temperature was 50-60 ℃;the membrane surface flow rate was 3.0 m/s.When the volume of filtration solution was condensed to 1/10 of former,entering the same volume deionized water into it,and when the effective components transfering rate reached 80%,the filtration was finished.Using the strong acid and strong alkali to wash it in turn,the flux could revive above 90%.Conclusion It can be obtained a good result that adopts the technology of ceramic membranes microfiltration to refine Radix Polygoni Multiflori Granula.This can provide the foundation for the application of ceramic membrane microfiltration in the refinement of water extraction of other Chinese materia medica.

ObjectiveTo study the clinical features and pathogenesis of ophthalmoplegia in senile patients with diabetes, and access the possibility of its development.MethodsBesides routine ophthalmologic and ocular muscle examination, general and laboratory examinations were also done. Some patients were diagnosed also with the help of image processing.ResultsMonocular involvement happened in all 21 patients. 12 patients suffered from oculomotor nerve paralysis, 5 abducent nerve paralysis, 3 trochlearis nerve paralysis, and 1 compound nerve paralysis. Among these patients with complete oculomotor nerve panalysis, no papillary change appeared.Conclusions Microvascular pathologic change may be the pathogenetic basis of ophthalmoplegia for senile diabetic patients. Its prognosis is favorable if reasonable treatment is made.

Objective To investigate the curative effect of damage control theory in treating severe polytrauma patients combined with bone and joint injury. Methods A retrospective study was done on data including complication, death rate, fracture healing and joint function recovery of 63 patients with severe polytrauma combined with bone and joint injury( average ISS ≥27 points) admitted to our hospital from January 2006 to June 2009. Results Of all the patients, 57 shock patients were cured,three died of hemorrhagic shock within two hours after admission and one patient died of severe traumatic brain injury 11 hours after admission. One patient died of ARDS at 24 hours postoperatively and one died of multiple organ failure at day 6 after injury. Fracture healing was achieved in 52 patients, with satisfactory recovery of the limb function. Amputation was performed in two patients and three patients had mild claudication and pain walking. Conclusion Damage control strategy has great clinical significance in guidance of treatment of severe polytrauma combined with bone and joint injury.
