Objective Optimizing the preparation technology of Red buttock ointment,by exploring the best extraction conditions of the alkannin,radix arnebiae seu lithospermi polysaccharides and so on.Methods Selecting radix arnebiae seu lithospermi 1kg and using orthogonal experiment to explore the best extraction conditions.Naphtho-quinone pigment chemicals were extracted by reflux extraction method;ethanol and paraffin wax were chosen as the composite solvent.Radix arnebiae seu lithospermi polysaccharide was extracted by water decocting,which to observe the rationality of process.Results The best extraction condition is A3 B2 C1 D1 , including section A:ethanol was 20 times the quality of medicinal materials (select radix arnebiae seu lithospermi 1kg and ethanol 20kg),section B:the amount of paraffin was 5% of ethanol(select radix arnebiae seu lithospermi 1kg and paraffin 1 kg),section C:Boiling water was 20 times the quality of medicinal materials,section D:the boiling time was 2h.Conclusion The more practical production process conditions:Ethanol was 10 times the quality of medicinal materials,and the amount of paraffin was 5%of ethanol.Boiling water was 10 times the quality of medicinal materials,and the boiling time was 1 h.This method is economic, simple, reasonable, stable, reproducible and easy to operation.Red buttock ointment obtained by this method possesses of excellent quality,good performance and superior effect.

Objective To explore the application effect of clinical pathway in clinical teaching for on -the-job training nursing staff in neurosurgery department .Methods Thirty-six nurses who accepted on-the-job training from March 2009 to December 2010 were selected as control group , and thirty-six nurses who accepted on-the-job training from March 2011 to December 2012 were selected as observation group .The traditional teaching method was used in the control group , and the teaching method of clinical pathway was used in the observation group .All nurses were trained for three months , who took the relevant exams on theory and operation at the end of each month , in order to evaluate their learning quality at each stage of learning .Nurse ’ s satisfaction with teaching was evaluated at the end of the on-the-job training .Results The score of theoretical knowledge, nursing operations and comprehensive quality ability was (93.51 ±4.61), (93.46 ±2.94) and (91.57 ±3.71) in the observation group, respectively, and (91.07 ±3.88), (91.29 ±2.87) and (88.44 ± 4.28) in the control group, respectively, and the differences were statistically significant (t=2.435, 3.173, 3.319, respectively;P<0.05).Nurse’s satisfaction with teaching was 100.00%(36/36) in the observation group and 83.33%( 30/36 ) in the control group, with statistically significant difference ( P <0.05 ). Conclusions Application of clinical pathway in clinical teaching for on-the-job training nursing staff can improve the quality of clinical teaching , mobilize the initiative and enthusiasm of teachers and nurses , and improve nurse ’ s satisfaction with teaching .
