Objective To identify the key factors triggering medical disputes induced by differences in cognition between doctors and patients in order to control the occurrence and development of medical disputes. Methods From 2002 to 2006,the outpatients,inpatients and medical staff of 3 hospitals in Shanghai(class 3 first level general hospital,n=2;class 3 first level special hospital,n=1) were investigated,and random sampling method was employed for the research analysis. Results There were significant differences between doctors and patients in cognition of influential factors triggering medical disputes such as health law,medical services,rights and obligations. Conclusion The differences in cognition between doctors and patients are important causes for medical disputes,and effective prevention and intervention measures must be taken.

To study the in situ intestinal absorption kinetics and compatibility influence of peimine and peiminine in rats, the absorption of peimine and peiminine in small intestine (duodenum, jejunum and ileum) and colon of rats was investigated using in situ single-pass perfusion method and the drug content was measured by HPLC-ELSD. Perfusion rate, pH, concentration of drug, gender and bile duct ligation can significantly affect the absorption of peimine and peiminine, the Ka, and Papp values in the condition of pH 6.8 and pH 7.4 had significant difference (P<0.01), as drug concentration irlcreased, the absorption parameters of peimine and peiminine decreased, Ka and Papp between low concentrations and middle concentrations was significant difference (P<0.01). Verapamil can not affect Ka and Papp of peimine and peiminine which are in the extract (P> 0.05). Bitter almonds and licorice can significantly reduce the absorption of peimine and peiminine with the usual dose (P<0.01), extracted separately and together had no significant difference on Ka and Papp (P> 0.05). Experimental results show that the absorption features of peimine and peiminine are basically the same, both of them could be absorbed at all segments of the intestine in rats and had no special absorption window, and with significant differences between male and female individuals. The absorption of peimine and peiminine complies with the active transport and facilitated diffusion in the general intestinal segments. Bitter almond and licorice can reduce the intestinal absorption rate ofpeimine and peiminine.

Objective To study the mutations of outer-membrane porin gerte (oprD) in imipenem-resistant Pseudomonas aeruginosa.Methods The PCR was applied to detect the oprD gene from the 34 clinical imipenem-resistant Pseudomonas aeruginosa.DNA sequence was proceeded to analysis the nuclentide sequence of the oprD gene and the deduced amino acid sequence.To analysis the mutation and the function of the oprD domain,those mutations were compaired with the standard Pseudomonas aeruginosa ATCC27853 and 2 clinical imipenem-susceptibility isolates.Results oprD gene mutation was wide and diverse.The rate of the mutation was 92.3% (12/13),mutations were concluded dot mutation,deletion mutation and insert mutation,those result in the amino sequence change and frame shift in L2 and L3 loops of outer membrane protein D,hampering the combine of oprD and imipenem.Some new mutations were found.They were 1 079,1 114,1 196,1 206,1 288,1 300,1 301 bases and 115,127,154,158,185,189 aminos.All above mutations were not deteced in ATCC 27853 and 2 clinical imipenem-susoeptibility isolates.Conclusions The wide and diverse mutations in oprD gene result in amino acid change and/or frame shift L2 and L3 loops,hampering the binding of IMP and oprD.Those may result in resistance to imipenem in Pseudomonas aeruginosa.

AIMTo find the cause of abnormal NMR spectra of lomerizine dihydrochloride, cetirizine dihydrochloride and flenfluramine camphoramide.

METHODSHypothesizing, in given conditions, there are changes of stereoisomeric conformation and configuration in structure of N-containing compounds, it results in abnormality of NMR spectra. By using the method of NMR, it is confirmed credibily.

RESULTS AND CONCLUSIONThe moving balance exists between two chair conformations in lomerizine dihydrochloride and cetirizine dihydrochloride. It causes that spin-nuclei of whole molecule are placed in two chemical circumstance. In solution of DMSO-d6, the speed of conformation reversal equals to the NMR time scale, so that chemical shift of spin-nuclei can not be definitely determined, peaks are broadened and even collapsed. After dropping D2O or increasing the temperature, the viscosity of the solution is decreased, the speed of reversal is quicker than NMR time scale, then normal spectra are obtained. Owing to the reversal of the three bonds of nitrogen in flenfluramine camphoramide is limited, other pair of diastereoisomer resulted from the asymmetric nitrogen can be detected by NMR. Multiplication of the peaks of 13CNMR is reasonably explained.
