Commercialization of the doctors sector and lawyers sector, and that of medical services, sharp rise of medical disputes and its impact on healthcare services have grown into major challenges for the healthcare system in the United States where litigation is the legal way out of medical disputes at large.Anglo-American law system depends heavily on precedence as the criteria and the majority of such disputes trials are held in state courts, there is also a complete system of laws and decrees on medical disputes on the federation level.In an effort to handle medical disputes that are rising sharply in a piling-up amount, American lawyers, social organizations of arbitration and medicine, and many state courts are seeking alternative dispute resolution as a better way out for medical dispute mediation and resolution.Given the gaps between China and USA in social systems, legal systems, ,economic development, cultural background, healthcare systems and heahhcare security systems, these experiences will prove their value of reference for medical disputes resolution in China.

Objective: To realize cycle management early warning function of measuring instruments. Methods: The software will visit the existing access log files of measuring instruments for the next test date. They are compared with the system date. Software will alarm when measurement instruments test cycle is about to expire. Results: By setting the parameters, the software can easily access the measuring equipment log files. It can effectively implement early warning function. Conclusion:Visual Basic6.0 achieved the development of this software conveniently, took up less system resources, powerful, effectively preventing the verification of measuring instruments and missed period expired to happen.

Objective To describe the anxiety of caregivers and condition management of preschool asthma children ,and analyze the relation?ship between anxiety and disease management. Methods A total of 208 caregivers of asthma children from two hospitals in Shanghai were select?ed using convenient sampling,and surveyed by self?rating anxiety scale(SAS),condition management ability scale and condition management diffi?culty scale. Results The score of SAS were negatively correlated with the condition management ability and positively correlated with the condi?tion management difficulty. Hierarchical regression analysis showed that the model explained 26.6%amount and 35.1%amount of variation respec?tively. Conclusion The anxiety of caregiver of children with asthma may affect the disease management. Future interventions should be strength?ened on the caregivers'psychological problems,so as to improve disease management and control asthma more effectively.

Objective To determine the changes in phosphorylation of conventional protein kinase C?(cPKC?)-interacting extracellular signal regulated kinase 1/2(ERK1/2) in the hippocampus of hypoxic preconditioned(HPC) mice.Methods Healthy male BalB/c mice were used to develop "auto-hypoxia"-induced HPC mice and randomly divided into 3 groups as follows: normoxic control(H0),early(H3) and delayed hypoxic preconditioned groups(H6).Co-immunoprecipitation and Western blot were applied to quantitatively analyze the phosphorylation level of cPKC?-interacting ERK1/2 in cytosolic and particulate fractions of hippocampus of HPC mice.ResultsERK1/2 was co-immunoprecipitated by cPKC? in hippocampus of mice.The phosphorylation level of cPKC? interacting ERK1/2 at tyrosine 204 decreased significantly in the hippocampus of H3 and H6 groups as compared with that of the H0 group(P

Objective The olecranon is likely to become shorter following the treatment of its comminuted fractures, which will lead to the compromise of the function of elbow joint. So through the cadaver experiment, introduce the method of making different thickness and direction in osteotomy so as to intimate the shape change of the olecranon after the comminuted fractures, and explore its effect on the flexion-extension function of the elbow joint. Methods Through three cadaver(six arms), osteotomy at 25 mm below the olecranon process was made horizontally and fixed with two screws temporarily, furthermore, the bone fragment of 1 mm, 3 mm and 5 mm in length was resected in order, then specimens were divided into two groups: In the first group, osteotomy was made up to 7 mm and 8 mm continually, and the changes of the range of the elbow joint movement were measured; in the second group, the additional wedge osteotomy of 5 mm and 7 mm was performed respectively, then the outcomes between the two groups were compared. Results If the osteotomized bone was within 3 mm, shortening internal fixation was satisfactory for the reconstruction of the elbow joint function. However, in cases of osteotomized bone of 5 mm, the extension function would be limited as the loss of the trochlear notch is too much. In order to keep the normal range motion of the elbow, the dorsal cortex distal to osteotomy should be scarified about 3 mm for the wedge osteotomy. When the shortage attained to 7 mm, the elbow instability would occur, even if advanced wedge osteotomy was accomplished. Conclusion In cases of the comminuted olecranon fractures, if the osteotomy is made within 3 mm, the shortening fixation is appropriate; if it has not exceeded 5 mm, the fracture should be treated with advanced wedge osteotomy tilting back to keep the radian of the trochlea; and if it has reached 7 mm, bone grafting is necessary for recovering of the flexion-extension of the elbow joint.

OBJECTIVE:To establish a method for the simultaneous determination of chlorogenic acid,hesperidin and baicalin in Shubiaoling granule. METHODS:HPLC was performed on the column of SAGA Tri-Sal C18 with mobile phase of acetonitrile-0.5%phosphoric acid(gradient elution)at a flow rate of 1.0 ml/min,detection wavelength was 320 nm,column temperature was 30℃,in-jection volume was 10μl. RESULTS:The linear range was 2.463-240.5μg/ml for chlorogenic acid(r=0.999 9),6.577-642.3μg/ml for hesperidin(r=0.999 8)and 1.708-166.8 μg/ml for baicalin(r=0.999 8);RSDs of precision,stability and reproducibility tests were no more than 1.8%;recoveries were 97.02%-102.40%(RSD=1.9%,n=6),96.55%-100.20%(RSD=1.6%,n=6) and 97.51%-100.70%(RSD=1.2%,n=6),respectively. CONCLUSIONS:The method is simple,accurate with high sensitivity and good reprosucibility,and can be used for the simultaneous determination of chlorogenic acid,hesperidin and baicalin in Shubiaoling granule.

Peroxisome proliferators -activated receptors γ(PPARγ)agonist is a kind of drugs that is widely used in the treatment of type 2 diabetes,also shows effects on hypertensive disease,regulating blood lipid metabolism, anti -atherosclerosis and inhibiting inflammatory response.In recent years,good effects of PPARγagonist have been found on different animal models of asthma,and production of proinflammatory cytokines can significantly be reduced. Airway remodeling can be reduced,and airway hyper responsiveness can be inhibited by PPARγagonist that provide theoretical basis on new drugs for asthma.The mechanism of bronchial asthma cured by PPARγagonists are reviewed briefly.

Objective:To explore the relation of the expression among C-erbB-2,p16 and nm23-H 1 protein in tissues of nasopharyngeal carcinoma(NPC)and its clinical significance.Methods:SP TMimmunohistochemical technique was used to detect the positive expression rate of C-erbB-2,p16 and nm23-H 1 protein in NPC tissues.Rusults:①The positive rates of C-erbB-2,p16 and nm23-H 1 in low differentiated squamous cell carcinoma were 58.75%,47.5% and 35%,while in undifferentiated squamous cell carcinoma, they were 86.67%,31.11% and 60% respectively. ②Their expression rate were significantly correlated with the clinical staging(P
