Objective To identify appropriate subjects for public hospitals social evaluation which fit and match the public hospital social evaluation index system.Methods The methods of literature review,expert consulting and comprehensive evaluation were used.SWOT analysis,appropriateness ranking and classification were made to such six evaluation subj ects as civil servants,medical workers, professional organizations,patients and their family,the public at large and mass media representatives. Results For the support dimension,the top three appropriate evaluation subj ects are professional social organizations,the public at large and medical workers in turn.For the process dimension,the top three subj ects are social professional organizations,civil servants and the public at large.For the result dimension,the top three are professional organizations,the public at large and civil servants.Conclusions Diversified evaluation subj ects independently represented and guided by non-government third-party professional organizations seem a better solution for China′s present specifics.Such a mechanism is authorized by the government,involving patients and their family,the public and social observers,and mass media representatives,supported and coordinated by government departments and public hospitals.

0.998. The detection limits were in the range of 16-40 ng/L(S/N=3).

Objective To investigate the methods for localization of the lung segments on three-dimentional (3D) pulmonary perfusion SPECT/CT imaging.Methods Twelve healthy adults were recruited into this study.Lung segments were defined based on the anatomical criteria of CT on transaxial, sagittal and coronal images, including apical, posterior, anterior segments in right upper lobe ( RUL), lateral, medial segments in right middle lobe ( RML), superior, anterior basal, lateral basal, posterior basal segments in right lower lobe (RLL); apical posterior, anterior, superior lingual, inferior lingual segments of left upper lobe ( LUL), superior, medioanterior basal, lateral basal, posterior basal segments of left lower lobe (LLL).Results (1) Eleven typical sections were selected on transaxial SPECT pulmonary perfusion imaging:sternoclavicular joint, supra-arch vessels, aortic arch, azygous arch, right upper lobar bronchus, left upper lobar bronchus, middle lobar or lingual bronchus, basal trunk of bronchus, lower lobar vein, superior and inferior basal vein and basal vein.(2) Twelve typical sections were defined on sagittal imaging:left hilum, bifurcation of left principal bronchus, septa of left pulmonary artery, cardiac apex, the first and second sections left to cardiac apex; right hilum, bifurcation of intermite bronchus, interlobar artery, bifurcation of interlobar artery, the second and third sections right to right atrium.(3) Seven typical sections were defined on coronal imaging:sternoclavicular joint, ascending aorta, bifurcation of pulmonary artery, bifurcation of trachea, intermite bronchus, basal vein and thoracic aorta.Conclusion The developed method was able to localize lung segments on pulmonary perfusion SPECT imaging.

Objective: To obtain the 12-mer phage clones displaying the Hantaan virus mimic epitopes.Methods: HFRSV-positive sera were used as selective molecules for biopanning.A 12-mer phage peptide library was bio-panned for 5 rounds,and the result was confirmed by sandwich ELISA,competition ELISA and DNA sequencing.Results: After 5 rounds of effective screening,the results detected by sandwich ELISA and competition ELISA showed that the majority of the selected clones could react to positive sera in a dose-dependent manner,but could not bind to BSA and the control sera.Sequencing and alignment analyses indicated that amino acid sequences of 45 positive clones fell into 8 groups,and 7 of them exhibited putative motifs: LVXKR,LTXR,IXKP,LXPA,VGA,KXIR and EKXP.Four of the putative motifs had a homologous region within the structural proteins of HFRSV.Conclusion: The peptides displayed by the phage can mimic the epitopes of HFRSV antigens,which provides the potential for preparing more effective epitope-based vaccines and specific diagnostic reagents.

Objective:To study the stability of total parenteral nutrition ( TPN) solution used in our hospital .Methods:The ap-pearance and pH of the compatibility solution were observed and the content of vitamin C was determined in 8 h after the compatibility . Results:The content of vitamin C in compound amino acid solution was decreased with the time , and the solution turned yellow in 4 h and the content of vitamin C was decreased by 10%, while no notable change in pH value was shown .The solution without compound amino acid was stable in 6 h.Conclusion:Vitamin C injection mixed with TNP solution containing compound amino acid is not recom-mended, and vitamin C should be used alone .

Objective To investigate the pathogenic bacteria and drug resistance in orthopedics patients, so as to guide the clinical use of antibiotics.Method708 secretions and pus samples from orthopedic outpatients and inpatients were cultured aerobically.The detectable bacteria were subjected to drug sensitivity test in vitro by the K-B assay.Result259 pathogenic strains were detected, and 47.9% of them were Gram-positive (Staphylococcus aureus, 33.0%: coagulase-negative staphylococci, 14.9%),and the remaining 52.1% were Gram-negative (Pseudomonas, 7.3%; Acinetobacter, 6.1%). The drug-resistant rate of Gram-positive cocci to penicillin and oxcillin tended to raise over the three years : however, all the detected Gram-positive cocci were sensitive to vancomycin (100%).Most Gram-negative bacilli were sensitive to imipenem (95.8%) in the past three years and the sensitivity to ceftazidime was also high; however, the sensitivity tended to fall over the past three years. The drug-resistant rates of Gram-negative bacilli to CiprofIoxacin. amikacin and piperacillin were 46.0%. 47.0% and 51.2% respectively.ConclusionGram-negative bacilli dominate the pathogenic bacteria in orthopaedic patients and they tend to increase. The incidence of infections by Gram-positive cocci is lower than that of infections by Gram-negative bacilli. In terms of individual bacteria ,staphylococcus aureus leads among all of these pathogenic bacteria, Vancomycin, Oxacillin and Norfloxacin are preferred drugs against Gram-positive cocci, while imipenem and ceftazidime are preferred for Gram-negative bacilli.The incidence of infections by Gram-negative bacilli tend to raise and drug resistance of Gram-negative bacilli becomes serious:hence, it is crucialOto emphasize the detection of infectious bacteria and drug sensitive test and to use antibiotics rationally.

Objective:To study the stability of thiamine nitrate ( VB1 ) and pyridoxine hydrochloride ( VB6 ) in total parenteral nu-trition ( TPN) solution containing multi-trace elements injection (Ⅱ) . Methods:HPLC was used to determine the contents of VB1 and VB6 in different prescriptions in 0, 2, 4, 6, 8 and 24 h. Meanwhile, the pH value was determined and the appearance of the solution was observed. Results:The contents of VB1 and VB6 in 5% glucose solution containing multi-trace elements injection (Ⅱ) were changed mithin the range of 10%. In the TPN solution, containing multi-trace elements injection (Ⅱ) , the content of VB1 decreased by 12% in 8 h, and the content of VB6 was changed within the range of 10%. The solutions containing multi-trace elements injection (Ⅱ) were all light yellow, while the solutions without multi-trace elements injection (Ⅱ) were colorless and transparent. The pH val-ue showed no significant change in each group. Conclusion: The TPN solution containing multi-trace elements injection (Ⅱ) and compound trivitamin B for injection (Ⅱ) is recommended to be used in 8 hours.

Objective:To establish an HPLC method for the determination of related substances in enalapril maleate dispersible tablets.Methods:AKromasil100-SC8(250mm×4.6mm,5μm)columnwasused. ThemobilephaseAwas0.01mol·L-1potassi-um dihydrogen phosphate (adjusting pH to 2. 2 with phosphoric acid) and mobile phase B was acetonitrile with gradient elution,and the flow rate was 1. 0 ml· min-1 . The detection wavelength was 215nm,the column temperature was 40℃,and the injection volume was 20 μl.

Enalaprilat was not detec-ted out and enalapril diketone was 0. 2% using the method described in Chinese pharmacopeia, and the content of enalaprilat was 0. 1% and that of enalapril diketone was 0. 2% using the gradient elution. The related substances and enalapril maleate could be sepa-rated well. Conclusion:The method is sensitive, accurate and highly specific in the quality evaluation and control.
