An analysis is made on major issues and difficulties in the application of the performance appraisal system structure,appraisal model and appraisal outcomes.It was discovered that the performance appraisal system,if used in clinical medical technology departments in the hospital,should focus on the system itself,the appraisal process and re-improvement of the system.These three factors are key to determining whether the system is effective and efficient,and key to transforming the system into departmental and hospital performance,even into overall enhancement of hospital performance in general.

d infrastructure quality.Conclusions Raising responsiveness for special medical services will be conducive for improving the quality of non-medical services for these inpatients when they are in the hospital.

Objective To investigate the status of parenting stress in the primary care-givers of children diagnosed with autistic disorder and sum up the nursing strategies. Methods Seventy-eight primary care-givers of children diagnosed with autistic disorder were interviewed using the parenting stress index-short form (PSI-SF). Results The mean score of parenting stress was 104.08 ± 18.32, which was at a high level. The 3 subscales score from high to low:parenting anxiety(36.22 ± 8.46);disabled children (35.64 ± 6.41);parent-child interation disorder(32.01 ± 7.15). Conclusion Medical staff should pay more attertion to these care-givers in order to enhance their ability to cope with various problems in the parenting process and hence reduce the level of parenting pressure.

Medical imaging is evolving from the traditional morphologic examination to a pattern that combines morphologic and functional examinations that can reflect physiochemical changes at cellular and molecular levels. Functional imaging techniques, including CT perfusion imaging, MR diffusion weighted imaging, MR perfusion imaging and MR spectroscopy, have been drawing increasingly more attention in pathological study of the livers, pancreas, kidneys, prostates and lymph nodes, and the prospect is promising. CT & MR functional imaging combined with morphologic examination is helpful for the diagnosis and differential diagnosis of pathological lesions.

Objective To observe the effect of motor relearning program (MRP) on balance function of stroke patients.Methods Sixty stroke patients were randomly divided into the MRP group and control group with 30 cases in each group. The patients of the control group were trained with proprioceptive neuromuscular facilitation (PNF) therapy; those of the MRP group were trained with the MRP therapy. The balance function of all patients was assessed with the Fugl-Meyer Balance Function Assessment before and after training.Results After training, the scores of Fugl-Meyer Assessment of all patients increased ( P<0.05), but scores of the patients of the MRP group were significantly higher than that of the control group ( P<0.05).Conclusion The MRP training can improve the recovery of balance function of stroke patients.

ObjectiveTo establish nude mouse tumor models bearing human pancreatic adenocarcinoma SW1990 cells in multiple sites at different time-points and investigate the feasibiilty of multiple tumor-bearing in these models; then the findings and detection rate of 3.0T magnetic resonance image (MRI) in subcutaneous transplanted tumors was analyzed. Methods A total of 6 BALB/C nude mice were randomized into 3 groups (2 mice per group ).At the 1st,8th,15th day,the mice were injected subcutaneously with the suspension of SW1990 cells at left axilla and right axilla and right groin in sequence.Three weeks later,all the bearing-tumor mice were performed with MRI non-contrast enhanced scanning plus Gd-DTPA enhanced scan and the subcutaneous masses were subjected to pathological analysis.ResultsAll the 6 nude mice were alive during the study and obvious mass was observed in every injected site.The tumor size was positively associated with the grwing time.There were 9 tumors which could be de.ted by noncontrast enhanced MRI scanning and one more tumor was detected by contrast enhanced scanning.2 tumors were not detected,the 2 tumors were located at subcutaneous of right groin,with the shortest growing time,and the major axis of the 2 un-detected tumors was less than 5mm.Despite the MRI findings of the transplanted masses similar to that of human pancreatic adenocarcinoma with bleeding,necrosis,they presented the characteristics of a clear rim,with pseudocapeule sign.All the 12 masses were similar with human pancreatic adenocarcinoma under light microscope.ConclusionsIt is feasible to transplant human pancreatic adenocarcinoma cell at three different subcutaneous sites (injected at three different points of time) in the nude mouse,with a minimal survival time of three weeks.However,routine 3.0T MRI cannot detect the early tumors (growing time within 1 week,major axis ＜5 mm).

Identification of seven species of Clematis L. (C. chrysocoma Fr.,C. amendii Fr.,C. fasciculiolia Fr.,C. ranunculoides Fr.,C. rubifolia C. H. Wright,C. florida Thunb. and C. brevicaudata DC. )was studied by RAPD analysis. Results showed that the differences of RAPD between different species were significant,but nonsignificant between same species obtained from different localities

Haemophilus influenzae (Hi) is a pathogen exclusively found in humans. It causes a wide range of infections from the upper respiratory tract to serious invasive diseases. Such as pneumonia, septicemia and meningitis. Strains of Hi are usually classif ied into six serotypes a to f and nontypeable H. influenzae (NTHI) according to the antigenicities and compositions of their polysaccharide capsules. Hib was a common cause of serious infections in younger children. The polysaccharide-protein conjugate vaccines against Hib had almost eliminated H. influenzae as a cause of pediatric meningitis. However, NTHI remains an important pathogen, particularly in children and the elderly. Efforts to understand and control NTHI disease have been hampered by the diversity of these bacteria. This review introduced the study progress about pathogenic mechanism of NTHI. In order to provide the help for development of vaccine, clinic treatment and prevent the occurrence of diseases causing by NTHI.

Cantharellus Adans. ex Fr., a member of the Cantharellaceae, Cantharellales, Homobasidiomycetes, Basidiomycota, is a widely distributed macro-fungal genus with an independent evolutionary lineage. It currently includes 65 species, of which 9 were recorded in China. In this article, research history of the genus was briefly reviewed and some controversial conclusions, especially the demarcation and naming of some taxa, discrimination among similar species, problems on C. cibarius Fr. and C. tubaeformis Fr.: Fr. complex, as well as their ecological conservation and bionic cultivation, are discussed based on the authors’ findings. Proposals for further research on biodiversities and sustainable utilizations were put forward at last.

The effect of Ultraviolet (UV) rays on the activity of parasporal crystal of Bacillus thuringiensis, var. Kurstaki HD-1 strain was studied by SEM, SDS-PAGE, bioassay and other methods. It was found that the morphology and surface structure of PC were damaged ,and its solubility in alkaline solution or silkworm gut juice was decreased after being irradiated by UV, the solubility was lost completely after a long time irradiation over 5 hours, so the processed PC could not be degraded into protoxin with insecticidal activity and was denatured.
