Objective To study the clinical and genetic features of Huntington's disease (HD). Methods The data of clinical information and heredity in 28 patients with HD from 6 Chinese families were analyzed retrospectively. Results There were 28 patients in 6 pedigrees, including 15 males and 13 females. The onset age of all patients was 26～72 years old and the course of disease was variable from 6 years to more than 20 years, and there were 6 gene carriers, including 2 males and 4 females. These patients mainly appeared progressively chorea movement, with mental abnormalities (3 cases), dementia (1 case),ataxia (3 cases), dysarthria and dysphay in late stag (10 cases). Brain MRS of one gene carrier demonstrated significant Lac inversion hump in bilateral lenticular nucleus. Six pedigrees showed autosomal dominant inheritance. HD patients and gene carriers had an abnormal expansion of CAG (n≥37). Moreover, in 4 pedigrees, the onset age was earlier in the subsequent generations. Conclusions HD is an autosomal dominant neurodegenerative disorder with genetic anticipation and diversified clinical presentations. The (CAG)n expansion at the IT15 gene is the disease-causing mutation in the six pedigrees.

Objective To explore the effect of high quality nursing care performing in the operating room and reasonable approach for assessment. Methods Stratified random sampling was used to select 93 nurses from two tertiary hospitals. The task performance and contextual performance was assessed before and after implementing a range of high quality nursing care program. Results The task performance scores and patient care, nursing information, nurse skills dimension scores respectively were 58.59 ±1.77, 19.27±1.16, 19.50±1.11, 19.80±0.70 after the operating room junior high quality nursing service project, which were 37.21 ± 1.92, 5.55 ± 0.86, 13.78 ± 1.12, 17.87 ± 0.98 before the implementation, the differences were statistically significant (t=-82.48--15.15, P<0.01). The performance scores and mutual support between colleagues, work out the extra burden, organizational support dimension scores were respectively 70.43 ± 2.94, 28.23 ± 1.21, 18.52 ± 1.29, 23.67 ± 1.86 after the operating room junior high quality nursing service project, which were 36.20 ± 1.79, 15.52 ± 1.94, 7.33 ± 1.11, 13.34 ± 0.87 before the implementation, the differences were statistically significant (t=-91.99--46.68, P<0.01). Conclusions The high quality nursing care program is a range of nursing service which can advance task performance and contextual performance of nurses in the operating room. Task performance and contextual performance are effective approaches by which high quality nursing care in operating room could be reasonably assessed.

Objective To discuss the influence of psychological education on the resourcefulness of perioperative breast cancer patients. Methods Two hundred breast cancer patients from a first-class hospital in Fujian province were randomly assigned to the control group, in which routine care was done, and an intervention group, in which psychological education curriculum was employed at three stages on the basis of routine care. The resourcefulness scale was used in both two groups before and after the intervention to evaluate the score of individual and social resourcefulness and the total score of resourcefulness in these two groups. Results As to the control group, the score on individual resourcefulness and the total score on resourcefulness before and after the intervention had no significant differences (P>0.05), but the difference in the social resourcefulness scores before and after the intervention was statistically significant (P<0.05). The differences in the scores on the individual resourcefulness, social resourcefulness and the total score on resourcefulness in the intervention group before and after the intervention were all statistically different (P<0.001). What′s more, the scores of individual resourcefulness, social resourcefulness and the total score of resourcefulness between these two groups after the intervention were statistically different (P<0.001) as well. The scores of the intervention group were significantly higher than those of the control one. Conclusion The psychological education can significantly improve the resourcefulness level of perioperative breast cancer patients, which can help individuals to manage stress effectively.

Objective To investigate the inclusion of ginsenoside Rg_3 with hydroxylpropyl-?-cyclodextrin (HP-?-CD) in aqueous solutions, inclusion molar ratio of host and guest molecules, and change of thermodynamic parameters during the inclusion process. Methods The measurements of the inclusion mechanism, inclusion molar of the host and guest molecules, and change of thermodynamic parameters were carried out by the following methods: phase solubility, IR, NMR, and TLC methods, respectively. Results The results indicated that the inclusion compound of ginsenoside Rg_3-HP-?-CD was formed. The content analysis of the inclusion compound showed that the inclusion ratio of ginsenoside Rg_3-HP-?-CD was 1∶1. The change in the thermodynamic parameters suggested that the inclusion could proceed (△G

Objective To identify the inclusion compound of ginsenoside Rh2 with hydroxylpropyl-?-cyclodextrin (HP-?-CD) in aqueous solution, and to investigate the change of thermodynamic parameters during the inclusion process. Methods The measurements of the inclusion mechanism, inclusion molar ratio of the host and guest molecules, and change of thermodynamic parameters were carried out by the following methods separately; thin layer chromatography (TLC), differential scanning calorimetry (OSC), infrared (IR) spectrometry, phase solubility method, and thermodynamic method, respectively. Results That all the phase solubility diagrams showed a typical AL-type in various temperatures and suggested the formation of a soluble complex of 1∶1 molar ratio. TLC and IR Spectroscopy confirmed that the significant interaction between the host and guest molecules was probably due to the inclusion of aglycone of Rh2 molecule into the hydrophobic cavity of HP-?-CD molecule. The change in the thermodynamic parameters suggested that the inclusion could proceed spontaneously (?G
