With the improvement of the living standards, people have higher demands for the public medical care, but the medical care has difficult to meet the need of the social development because of the lack of trust-honesty. The article points out the dangers of the lack of trust-honesty, analyses the reasons to this phenomenon, and also probes into the countermeasures to solving this problem from the point of supervision of the government, self-discipline of hospitals, social environment, and so on.

Objective To study the changes of nitric oxide synthase in placenta during fetal cardiac bypass. Methods Eight pregnant ewes (gestation 120～140 d)were divided equally into control group and bypass group. Bypass group underwent fetal cardiac bypass with centrifugal pump and placenta. Fetal hemodynamic date and blood gas value were recorded before and after bypass. Placenta vascular resistance was calculated. Fetal serum nitric oxide (NO), serum endothlin-1(ET-1) and nitric oxide synthase (NOS) of placenta tissue were assayed. Transcriptions of endothelial NOSmRNA in placental tissue were assayed with RT-PCR technique. Results Acidosis and pressure of oxygen decreased after bypass appeared in fetal lamb of bypass group. Placenta vascular resistance of bypass group elevated significantly (P

OBJECTIVE:To provide reference for development of hospital pharmacy and clinical pharmacy in south Sichuan. METHODS:Questionnaire was used to investigate the general situation of secondary and tertiary hospitals in 4 cities of south Sich-uan in aspects of partition layout,staffing situation and job content. The results were statistically analyzed. RESULTS:A total of 40 questionnaires was sent out,35 were effectively received with the effective rate of 87.50%. The partition layout was unreasonable in most surveyed hospitals,and the rate of reaching the standard about the area of drug dispensing sector and warehouse was below 85%. There were 1042 pharmacists in 35 hospitals,which were mainly female of younger than 45 years old. In secondary and ter-tiary hospitals,the rate of pharmaceutical professional and technical personnel of health technology,full-time undergraduate and vice-high above title accounted for 4.78% and 3.67%,17.37% and 31.27%,3.15% and 10.73%,respectively. The number of full-time clinical pharmacists was 24 and 69 in secondary or tertiary hospitals,mainly primary title,middle title and undergradu-ate,of whom 26(27.96%)passed job training of National Health and Family Planning Commission,4(4.30%)passed teaching qualifications training. The rate of pharmacists mainly engaged in drug dispensing and clinical pharmacy was 6.32% and 11.03% in secondary and tertiary hospitals,respectively. CONCLUSIONS:The research shows irrationality of partition layout,the shortage of highly educated and highly titles personnel,especially the clinical pharmacy professionals. The large differences exist in hospitals of different levels in several aspects,and the main body of hospital pharmacy should turn to clinical pharmacy.

Objective In order to understand the mechanisms beyond lipid regulation of 3 hydroxy 3 methyl glutaryl coenzyme A(HMG CoA) reductase inhibitors in anti atherosclerosis, we observed the influence of pravastatin on the pathogenesis of atherosclerotic lesions and the expression of intercellular adhesion molecule (ICAM) 1 in aortic wall of the apoE deficient mice. Methods Pravastatin(10 mg?kg?d -1 ) was fed to 10 , 20 , and 30 week old male apoE deficient mice respectively for 4 weeks. The atherosclerotic plaque size and the ratio of plaque area to aortic luminal area (PA/LA) were determined by histochemical staining and analyzed quantitatively. The expression of ICAM 1 in aortic wall of apoE deficient mice was detected by immunohistochemistry and Western blotting. Results Compared with controls, pravastatin delayed the plaque formation in apoE deficient mice 〔(161 786 1?38 041 2) ?m 2 vs (99 127 9?13 600 3) ?m 2, P

Objective To investigate the way of fear conditioning memory model evoked and erased by foot-shock in tree shrew. Methods First, detect the tree shrew activities regularly in light/dark box. Second, test a suitable voltage degree of foot shock on tree shrew. Third, investigate the memory formation and erasing of fear conditioning on tree shrew of trial group. Results The duration of tree shrew (n=4) stay in the dark-box was significantly lon-ger than that of in the light box (P<0. 01) in normal condition. In the same environment of two light boxes, given different voltage degrees, the durations of tree shrew (n=6) stay in the stimulating chamber gradually reduced and the durations of tree shrew stay had significant difference between stimulatus chamber and no stimulatus chamber when the stimulus voltage up to 12 V ( P<0. 05 ) , 16 V ( P<0. 01 ) and 20 V ( P<0. 01 ) . The animal of trial group ( n=4 ) could build up the fear conditioning memory of the dark box with the stimulus of 16 V foot-shock in the dark box ( P<0. 001 ) . After formation of the fear conditioning memory, the same stimulus in light box ap-peared for 4 days. The durations of tree shrew stay in trial group (n=4) decreased in light box, and there was no significant difference between the trial group and the control group. Conclusion Tree shrew prefers to stay in the dark box. The suitable voltage for foot-shock on tree shrew is 16 V. The fear conditioning memory can be evoked and erased by foot-shock.

Synovial sarcoma is a malignant soft tissue with unknown origin. Although head and neck region is the second common site of involvement, rare cases have been reported in Para nasal sinus and larynx. We presented two cases of synovial sarcoma, one of which arised from maxillary sinus and the other from laryx, and re- view the literature to sum up the diagnosis and treatment strategies. The conclusion is that synovial sarcoma in the head and neck still raises diagnostic and therapeutic issues. Surgical excision with wide margins is essential and necessary, usually associated radiotherapy. The effect of chemotherapy remains to explored.

Objective To investigate the distribution and drug resistance of Pseudomonas aeruginosa(PAE) in the hospital ,so as to provide the reference for the rational drug use and the infection control in clinical .Methods The infection distribution and drug resistance of 822 isolates of PAE were analyzed .The drug sensitivity test was proceeded by dilution method ,and the results were judged according to the relevant documents of the CLSI .The data was analyzed by WHONET 5 .6 software .Results 822 isolates of PAE were mainly distributed in intensive care unit ward ,general surgical department and respiration department .The sample was 82 .1% from sputum .The infection rate was the highest in autumn(30 .0% ) .The drug resistance rate of PAE to cefperazone/sul-bactam was the lowest(7 .6% ) ,and which to amikacin was 19 .1% .The resistance rates of PAE to other drugs were all higher than 20 .0% .Conclusion PAE is a common pathogen of respiratory tract infection ,which has a high resistance rate to the current clini-cal antibacterial agents ,and doctors should pay attention to the infection caused by PAE .

Objective To study the clearance of high risk human papillomavirus(HPV)infection among the women with normal cervical pathologic diagnosis.Methods One hundred and seventy.two HPV-positive cases with normal cervical pathologic diagnosis were enrolled in the study.The infection status of HPV was monitored during follow-up from Aug 2006 to Aug 2008.The time of HPV infection spontaneous clearance,as well as effect factors,were analyzed.Results During follow-up,there were 62.2%(107 cases,107/172) of the HPV infection cleared.The medium clearance time was 11.3 months(95% CI:10.6-16.6 months).The medium clearance time of aged<30 years,30-39 years,40-49 years and>49 years were 11.3,12.0,10.9 and 8.5 months.respectively.There were not significant difference among aged intervals (P=0.384).The virus copies of HPV-clearance cases and persistent-infection were 22.6 and 95.0,respectively.There was not significant difference between groups(P=0.061).Conclusions Most of the high risk HPV infection with normal cervical pathologic diagnosis would spontaneously cleared.Age and HPV copies may play little role in the HPV clearance.
