Errors and flaws of clinical nursing practice can be fully exposed to voluntary reporting system of nursing errors, and then dramatically improving patient safety. This paper aims at exploring the theoretical basis, the characteristic of the system and essentiality for establishing voluntary reporting system of nursing errors, introducing the methods practicing both in abroad and in domestic, explaining its precondition and put forward a suggestion that the voluntary reporting system would be established in our own country.

Objective To explore the effect of endoscopic sinus surgery on inverted papilloma of nasal cavity and paranasal sinuses in 30 cases.Methods 30 patients with inverted papilloma of nasal cavity and paranasal sinuses were operated on by endoscopic sinus surgery.Results During a follow-up of 2～3 years,only four cases recurred, Conclusion Endoscopic sinus surgery had advantsges of clear field and little injury,and therefore it was effective for inverted papilloma of nasal cavity and paranasal sinuses.

Zymonomas mobilis was transformed with a polyhydroxybutyrate synthesis operon phbCAB equipped with a pdc promoter from Z. mobilis. For the first time,PHB was produced in recombinant Z.mobilis. Shake flask studies indicated that accumulation of PHB in Zymomonas mobilis increased approximately 10% ethanol productivity for the first 48h of anaerobic fermentation. After that,the PHB effect was observed as insignificant probably due to the exhaustion of the sugar.

This paper analyzes the present situation and focuses of medical image fusion and especially places emphasis on the developing trend of intelligent image fusion and comachine image fusion technologies.

The quality control method and standard were established to control the quality of Pteris multifida in this paper. The tests of water content, total ash, acid-unsoluble ash and ethanol-soluble extractives of P. multifida were carried out according to the methods recorded in appendix of Chinese Pharmacopeia (2010 edition, volume 1) . The TLC method was established by using rhoifolin as references, and a mixture of CHCl3 -MeOH-HAc (6: 1: 1) as the developing solvent system on GF254 thin layer plate. The contents of rhoifolin was determined by HPLC on a Diamonsil C18 (4.6 mm x 250 mm, 5 μm) column, using acetonitrile-water (containing 0.15% formic acid) (16: 84) as mobile phase at a flow rate of 1.0 mL x min(-1). The column temperature was 30 degrees C and the detection wave-length was 350 nm. As a result, pterosin C 3-O-β-D-glucosidede and the other constituents were well separated on TLC detected under the UV light at 254 nm . The methodology validation for the assay of rhoifolin presented that it was in good linear correlation in the ranges of 0.025 5-5.1 μg with the regression equations of Y = 1 092.4X + 9.503 5 (r = 0.999 8), and the average recoveries were 100.3% (RSD 1.3%). The content range of rhoifolin from 16 different batches of Pteris multifida was 0.08-5.06 mg x g(-1). The water content, total ash, acid-unsoluble ash and ethanol-soluble extractives of 16 samples varied in the ranges of 7.35% - 12.96%, 6.90% - 16.33%, 2.07% -11.38% and 13.29% -23.87%, respectively. The suggesting limes in the quality standard for water content, total ash, acid-unsoluble ash, ethanol-soluble extractives and rhoifolin content were ≤ 12% , ≤ 15% , ≤ 8.5% , ≥ 14% and ≥ 0.040%, respectively. The result proved that the established quality of control method was specific and accurate, which can be used for the quality control of P. multifida.

Objective To investigate the status and influential factors of mental health of Pakistani and Bangladeshi peacekeeping forces in Liberia.Methods By random sampling,300peacekeeping officers and soldiers dispatched from Pakistan and Bangladesh(150 each)in Liberia were investigated with Chinese Military Mental Health Scale(CMMHS),Military Mental Maladjustment Scale(MMMS) and Social Support Rating Scale(SSRS),and they were carried out for two times on the 7th day and the 120th day after arrival in peacekeeping mission area.Results The total score and each factor score of CMMHS(except for obsessive-compulsive,anxiety and interpersonal sensitivity)and the total score of MMMS of the peacekeepers at the 7th day after their arrival in mission area were significantly higher than those at the 120th day(P

· AlM: To explore the correlation of center retinal thickness and axial length in non-proliferative diabetic retinopathy ( DR) .
· METHODS:A total of 80 cases ( 155 eyes ) of non-proliferative DR patients were divided into three groups according to the axial length, 22~24mm of 27 cases (51 eyes) were normal group, 24 ~26mm of 28 cases ( 55 eyes) were long axis group, >26mm of 25 cases ( 49 eyes) were super long axis group.The center retinal thickness and ocular axial length of three groups were measured and the correlation of center retinal thickness and axial length were analyzed.
· RESULTS:Among the inner ring and outer ring, the center retinal thickness of upper and lower, bitamporal and nasal side of super long axis group was thicker than that in normal group, with statistically significant difference ( P<0.05 ); Among the inner ring and outer ring, the center retinal thickness of upper and lower, bitamporal and nasal side of super long axis group was thicker than that in long axis group, with statistically significant difference ( P<0.05); The DR central macular of retinal thickness was no correlation of the axial length ( P >0.05 ), but retinal thickness get thinning with increased of axial length on the inner ring and outer ring area, showed a negative correlation ( rinner ring =-0.63, router ring=-0.67, P<0.05).
·CONCLUSlON:Center retinal thickness and ocular axial length in non -proliferative DR patients, and center retinal thickness of super long axis patients are thinning obviously.
