Chinese Journal of Practical Nursing 2012;(36):66-69
Objective To test the reliability and validity of international physical activity questionnaire (IPAQ) in patients with hypertension.Methods It used international physical activity questionnaire and PA diary to evaluate the physical activity of patients with hypertension.Results The two re-test coefficients of IPAQ were related in hypertensive patients with different blood pressure level and physical activity.The energy consuming of different level of physical activity and total physical activity was correlated to each dimension of IPAQ.The first Spearman coefficient was 0.27~0.61,0.28~0.58 for the second time.Conclusions IPAQ had better reliability and validity,and could be used in hypertensive patients.

This study was aimed to analyze the similarities of characteristics between members of“metal family” in the five elements. Wittgenstein’s family resemblance theory was used in the analysis of members assigned to the category of“metal family”, which included metal, autumn, west, white, pungent and lung. The results showed that there was family resemblance between members of“metal family”. It was concluded that members were classified into the category of“metal family” through analogical reasoning of family resemblance. Any member to be classified as a member of“metal family” showed similarity with at least one of other family members. Certain member in the“metal family” had similarities in different aspects with multiple members in the family. Any two members of“metal family” may not always have any similarities. It can be deduced that certain physiological functions of lung were not owned by the lung itself, but by the characteristics of“metal family”. The range of“metal family” can be expanded and multiplied. The“metal family” can build new members in different areas.

Objective To evaluate the treatment of interapleural talc on the patients with malignant pleural effusion.Method There were 44 patients with malignant pleural effusion in the study.Every cases was inserted a chest drain to release the effusion with the rate of 200 ml per 2 hours.When there was no evidence of fluid in the pleural space as assessed by plain chest roentgenography,the talc slurry containing 4 g talc、40 ml of saline solution (0.9%) and 5 ml of 2% lidocaine was injected via the intercostal drain into the pleural space.An additional 20 ml of saline solution was used to flush the drain.Then,the drain was clamped,and the patient was asked to change position to allow adequate distribution of talc.After 2 hours,the drain was opened again.When the drainage decreased to less than 150 ml per 24 hours,the chest drain was removed.Result complete success was observed in 36 cases (81.8%),partial success in 6 cases (13.7%),and ineffective success in 2 cases (4.5%).There were 21 (47.7%) and 24 (54.4%) cases experienced pleuritic pain and fever after talc pleurodesis respectively,1 cases suffered from respiratory insufficiency which controled by using glucocorticoid later.Conclusion The talc pleurodesis is an effective treatment for the patients with malignant pleural effusion.It is safe and easily performed,and should be used extensively in clinic.

Protein-protein interactions and recognition are the focal and hot themes of the life science field in the 21st century. Molecular docking approach is the effective computer modeling technology in the study of this topic. Generally, the protein-protein docking procedure is composed of four stages: searching of the binding modes of the receptor and the ligand, filtering of docked modes to eliminate the irrational docked structures, optimizing the structures, evaluating the docked modes with the refined scoring function and ranking them to obtain the near-native structures. Combining the research group's works, in terms of the international and national progress of protein-protein docking approaches, the detailed review was made about the four stages mentioned above. Additionally, the existing major questions are analyzed and the prospects of the future study are made.

Objective To establish a method of gas chromatography with head-space sampling for determination of five residual solvents ( acetone, ethyl acetate, isopropanol, dichloromethane, acetonitrile ) in raw material drug of cefotiam hexetil hydrochloride. Methods Agilent DB-624 capillary column(30 m×0.53 mm,3.0 μm)was used,with FID served as detector and DMF as the solvent. Results Linear relationships were obtained for the 5 residual solvents in their respective concentration ranges ( r=0.999 6-0.999 9,n=5) ,and the detection range was from 0.071 to 0.847μg. The stabilities measured as relative standard deviations ( RSD) for the 5 residual solvents were from 0.40% to 2.12% ( n=3) . The average recovery rates were 99.03% to 103.33%,and RSD were 0.54% to 3.41% ( n=3) . Conclusion The method is simple,sensitive and accurate for the residual solvent analysis in raw material drug of cefotiam hexetil hydrochloride.

Objective To investigate the level of illness uncertainty and coping styles of parents of children with diabetes mellitus and their relationship, and provide theoretical basis of clinical intervention. Methods Totally 155 patients of children with diabetes mellitus were investigated with General Information Questionnaire, Parents′ Perception of Uncertainty Scale (PPUS) and Coping Health Inventory for Parents (CHIP) to analyze the correlation between illness uncertainty of parents and its influencing factors and coping styles. Results The total score of illness uncertainty was 80.15±10.38 in parents of children with diabetes mellitus. There was significant difference in total uncertainty score in parents with different number of children, parent′s age, education degree, profession, economic conditions and locations (P < 0.05). Coping style, education and Parent′s age entered into the multiple linear regression equation of illness uncertainty, predicting 23.2% of total variation in illness uncertainty. The level of illness uncertainty was negatively associated with coping styles (P < 0.01). Conclusions The illness uncertainty was at higher levels in parents of children with diabetes mellitus. Clinical nurses should measure illness uncertainty of parents of children with diabetes mellitus and improve their coping capacity to reduce illness uncertainty, so as to provide better services of family and promote the quality of life for children .
