Objective: To compare the efficacy of traditionary fusiform-shape excision, micro incision curettage and radiofrequency ablation in the treatment of osmidrosis. Methods: One hundred and eighty-six patients with osmidrosis were treated by traditionary fusiform shape excision method （20 cases）, micro incision curettage （116 cases）, and radiofrequency ablation （50 cases）. The therapeutic effects and complications were retrospectively analyzed. Results: The patients were followed up for 3 months to 1 year. The cure rate was 100%, 97.7% and 68.4%, respectively. Conclusion: All three methods are effective for the treatment of osmidrosis. The odor symptom could be improved a lot with traditionary fusiform shape excision method, which however would cost lots on complication, aesthetic improvement and convalescent period. The radiofrequency ablation was with smallest injuries and high relapse rate. Micro incision curettage was efficacy and aesthetic.
The empirical study of tourist bar culture sensation in Dali Old Town indicates that tourists hold approval attitude toward the sensation of spiritual experience and the sensation of cultural communication. For the sensation meets the tourists' need for relaxation and cultural exchange. The degree of approval is not high for experiencing foreign styles or understanding the local customs of the destination. The bars seldom embody the local style or local culture.

The nursing fee refers to the compensation for the losses incurred by nursing service to a victim who has got injury physically. The corresponding losses include the payment for employing nurse(s) and the reduced income due to missing working time of non-nurse (the victim's family member who took care of him). Nursing fee compensation shall not be subject to hospital's approval or demand. As a genuine economic loss, the reduced income of victim's family member due to missing working time shall also be compensated. As to the relevant judicial interpretation in China, there is room for improvement. In particular, in the criteria for nursing fee compensation there should be distinction between nurse and non-nurse, rather than distinction between non-nurse with fixed salary and non-nurse without fixed salary. Where non-nurse is in charge of taking care of victim, he shall have the right to claim compensation.
Objective: To determine the total alkaloids content in Senecio scandens Buch.-Ham. Methods: Using the oxymatrine as standard, acid dye colorimetry was used to determine the total alkaloids content in S. scandens at the wavelength of 422 nm. Results:The concentration of oxymatrine showed good linearity in the range of 6.75-135 μg （r=0.999 2）, the average recovery was 100.0%（RSD=1.54%）. Conclusion: The method is simple, reliable and can be used for determination of the total alkaloids in S. scandens.
Objective: To understand the polyphenols and vitamin C content changes in different teas after storage. Methods: Ferrous tartrate colorimetric method and fluorescence method were applied to detect the content of tea polyphenols and vitamin C in black and green tea before and after 6-month-stored. Results: Data showed no statistical significances in tea polyphenols content（P>0.05）but different vitamin C contents（P<0.05）before and after 6 months storage in both black and green tea. Compared to the black tea, green tea exhibited higher tea polyphenols content（P<0.05）, and same vitamin C content（P>0.05）. Conclusion: The content of tea polyphenol could not be easily lost by sealing after opening in dark. vitamin C could be oxidated and reduce.
In this paper, the half-wave loss of reflection of mechanical wave was proved using Euler's formula, under the nonisolated and non-slip boundary conditions. It takes the relationship between vibration and fluctuations as a starting point. The phases of incident waves and reflected waves were also calculated when taking "fixed -end" and "free -end" boundary conditions,respectively.
Objective: To study the effect of QCC in reducing the incidence rates of the falling of inpatients. Methods: QCC was founded by volunteers. The theme of the activity was made and the plane was settled. Sixteen falling cases happened in the internal medicine department at a hospital in Dali from January 2013 to January 2014 were analyzed. The correlates of incidence were mainly studied and the countermeasures were proposed. Then the incidence rates before and after the activity were compared to evaluate the effect and establish a standardized management. Results: After the activity, the incidence rates of falling of inpatients decreased from 0.009% to 0.005%. Conclusion: The application of QCC can reduce the incidence rates of falling of inpatients and play a remarkable positive role in promoting the group cohesiveness and abilities of QCC members in solving problems.
