The patient doctor relationship has a favorable turn through preventing ard treating SARS.People have begun to recognize the main factor is ethics problem to the patient doctor relationship.

"medical dispute profiteer" a deterioration of the doctor-patient relationship and sign an inevitable result,it not only undermined the hospital's reputation,disrupting the normal order of medical,but also to build a harmonious society will have an extremely negative impact.The spread of "medical dispute profiteer",attracted academics and the industry's attention.To make medical conduct a comprehensive study of the medical guarantee the normal order and promote health care in a sustained,rapid and healthy development of the broad masses of people to enjoy the harmony of health services is of great significance.

The regulation how to deal with unskillful and faulty medical treatment is a policy and legal document.It is a implement to the measure how to deal with unskillful and faulty medical treatment. It will make doctor and patients on an equal basis.

Objective To study the changes in parameters of blood flow and frequency-spectrum appearance in superior mesenteric artery (SMA)and inferior mesenteric artery(IMA) in the patients with ulcerative colitis(UC). Methods The parameters of blood flow and frequency-spectrum of SMA and IMA in 16 cases of patients with UC were observed before and after treatment, and 10 healthy volunteers served as control. Results The parameters of blood flow of IMA in patients with left half colon UC (9 cases) and all colon UC (7 cases) significantly changed after treatment(P

Objective To develop a method for the determination to organochlorine pesticides by gas chromatography-mass spectra-mass spectra.Methods The temperature of inlet was 250 ℃,the injection volume was 1 ?l,without split injection.The temperature of EI source was 300 ℃,the ionization energy was 70 eV,solvent delay time was 3.75 min,transfer line temperature was 280 ℃.181,235,246(m/z)were selected as parent ion,and 145,165,176(m/z)were sub ion.Results In the range of 0-50 ?g/L,every component had a good linearity,r≥0.99,the limit of detection≤0.01 ?g/L.Its average rate of recovery was in the range of 86.1%-101.8%,and the relative standard deviations(RSDs) were between 4.41%-8.07%.Conclusion Gas chromatography-mass spectra-mass spectra is more precise for the qualitative and quantitative determination of trace organochlorine pesticides residues in drinking water.

Objective To investigate the effect of thalidomide and As_2O_3 to the secretion of VEGF of the cell of ANLL and study if there is coorperation in thalidomide and As_2O_3.Methods From October 2001 to February 2003,23 patients with ANLL were analyzed.Heparinized marrow was taken,then it was putt into Ficoll-isopaque solution to be purified for MNC,which was cultured in the RPMI 1 640 medium,placed in 5% CO_2 saturation and 37℃ to proliferation.Choosing the cells in logarithm growth phase,adding cultural solution to abstaining the cellular density of 2?10~9/L and then putting it into 24-well plates.There are 4 groups :contrast group,thalidomide(300 ?g?mL~ -1 )group,As_2O_3(25 ?mol/L)group,and thalidomide(300 ?g?mL~ -1 )andAs_2O_3(25 ?mol/L)group,cultured for 72 hours.Examine the concentration of VEGF in upper liquid with ELISA method.Results The concentration of VEGF in upper liquid of 4 groups were respectively(1 582.67?281.51)ng/L、(1 206.29?264.87)ng/L、(941.72?236.34)ng/L、(639.12?211.98)ng/L.There were statisticd difference(P

Objective To determine in vitro susceptibility of itroconazole,voriconazole,caspofungi,and amphotericin B against 82 clinical strains of filamentous fungi.Methods Etest method was used to test the in vitro susceptibilities of itroconazole,voriconazole,caspofungi,and amphoteriin B against aspergillus fumigatus,A.flavus,A.niger,A.terreus,A.nidulans,et al.Results The MIC range of 4 antifungal agents were 0.03~2.00 mg/L and 0.01~32.00 mg/L against A.fumigatus and A.flavus,respectively.But amphotericin B had higher MIC90 value which was 16mg/L against A.flavus than A.terreus(MIC90 3.00 mg/L),A.fumigatus(MIC90 0.75 mg/L),and A.niger(MIC90 0.25 mg/L).Conclusion Itroconazole,voriconazole,caspofungi,and amphotericin B have different susceptibility patterns against various types of filamentous fungi.It's necessary to identify fungi to level of species and perform antifungal susceptibility test in serious patients.

Objective The aim of this study was to evaluate the in vitro activity of Ciprofloxacin(CIP)or Amikacin(AK)combined with four clinically-used antipseudomonas ?-lactams against multidrug-resistant Pseudomonas aeruginosa strains.Methods Determining the MICs of six antibiotics to 35 clinically isolated Pseudomonas aeruginosa strains which have different resistance patterns by 2-fold broth dilution method;determining the in vitro activity of Ciprofloxacin or Amikacin combined with Ceftazidime(CAZ),Imipenem(IMP),Meropenem(MEM)and Piperacillin/Tazobactam(TZP)by broth checkerboard method.Results The combinations of Ciprofloxacin or Amikacin with four ?-lactams have mainly synergistic or additive effect,the synergistic rate of AK-group(AK+CAZ:71.43%;AK+IMP:42.86%;AK+MEM:54.29%;AK+TZP:85.71%)was higher than that of CIP-group(CIP+CAZ:20%;CIP+IMP:25.71%;CIP+MEM:14.29%;CIP+TZP:31.43%).The combination of CIP+TZP has the highest synergistic rate in CIP-group;the combination of AK+TZP has the highest synergistic rate in AK-group.None of the combinations had an antagonistic effect.Conclusion the combination of ciprofloxacin or amikacin with ?-lactams have good in vitro activity to multidrug-resistant Pseudomonas aeruginosa strains.

Objective:To find out the situation of the use of the nutrition support drugs in Peking University Shenzhen Hospital.Method:The method of the use of the nutrition support drugs was adopted to analyze its situation in the hospital during 2005-2006 with respect to the sum of money,frequency of use,increase of charge for medicine and kinds of drugs.Results:The sum of money has been descent 70 000 yuan in 2006 than in 2005,and the frequeacy of use also has been descent 60 000.Conclusion:Parenteral nutrition(PN)drugs were more frequently used than enteral nutrition(EN) drugs.EN was advocated to be used as early as possible so as to maintain the intestinal tract mucosal barrier and recover the intestinal tract function.EN was fit to the physiological need and more scientific than PN.

Objective: To examine the temperament of childhood epilepsy. Methods:Subjects were 84 children with epilepsy diagnosed by criteria of ILAE (international league of anti-epilepsy) 1981 and 168 normal children. Their temperament was assessed with Carey's temperament questionnaires (for parents).Results:Children with epilepsy had higher scores on activity level (3.4?0.6/3.1?0.7,t=5.38,P
