Objective To evaluate the effect of pain management training to junior nurses' practice of pain assessment,to provide evidence for continuing education of pain management.Methods 60 junior nurses were randomly assigned to experimental group(30 cases) and the control group (30 cases).Nurses in control group received convention education,whereas nurses in experimental group received a pain management training for four weeks.The practice of pain assessment of two groups were compared after 4-week training.Results After training,the knowledge and attitude of pain management of nurses in experimental group scored an average of (29.20 ± 3.25),whereas the average score of nurses in control group is (16.83 ± 2.87).There was significance difference between two groups (t =-15.625,P ＜ 0.01) ; in terms of the contents of pain assessment,nurses in experimental group were more sufficient and more accurate (t =-14.726,P ＜ 0.01).Regarding the practice of pain assessment the mean score of nurses in experimental group and control group were (6.70±1.47) and (2.93 ±0.87).There was significant difference between two groups (t =12.11,P ＜0.01).For using pain assessment tool,the nurses in experimental group get 100.0％ correct rate,whereas nurses in control group get 30.0％ correct rate,which shows significant differences statistically (x2 =27.81,P ＜ 0.01).Conclusions The pain management training can improve nurses' pain knowledge,attitude,as well as promote the accuracy of nurses 'assessment practice consequently.

Objective To compare the effect of autologous bone marrow stem cells transplantation on liver function between first and second transplantation in decompensated liver cirrhosis patients.MethodsA total of 45 decompensated liver cirrhosis patients were enrolled, and 23patients in first transplantation group were transplanted with autologous bone marrow stem cells through femoral artery when condition was stable after medical treatment.In second transplantation group, 22 patients were accepted second transplantation in 4-12 month after the first transplantation.All the patients undergone routine blood test, congulation test and liver function examination at the fourth week and eighth week after transplantation.ResultsEight weeks after transplantation, the liver function was improved obviously in both first and second autologous bone marrow stem cells transplantation.The level of albumin in patients of second transplantation group increased from (37.26± 5.90) g/L before transplantation to (42.49 ± 4.80) g/L (P＜0.01), alanine aminotransferase (ALT) decreased from (57.05±45.51) U/L to (44.86±29.19) U/L (P＜0.05),aspartate aminotransferase (AST) decreased from (39.14-±-15.07) U/L to (53.73 ± 24.98) U/L(P＞0.05).Congulation parameters were also improved, prothrombin time (PT) decreased from (16.15±3.01) s to (14.63±2.32) s (P＜0.01), fibrinofen (Fib) increased from (2.44±0.61) g/L to (3.00±0.81) g/L (P＜0.01).Compared with first transplantation group, the albumin level was higher in second autologous bone marrow stem cells transplantation group, which increased from (38.00±6.33) g/L to (42.49±4.80) g/L (P＜0.05), AST and ALT also improved obviously, and there was significant difference between two groups.Meanwhile, Child-Pugh scores decreased from (7.22±0.67) to (6.67±[0.71) (P＜0.05).But there was no significant difference in bilirubin, FIB and PT.ConclusionThe second transplantation of autologous bone marrow stem cells could further improve liver function and maintain symptoms remission of liver cirrhosis.

OBJECTIVETo study effects of different interval year on Panax notoginseng plant soils middle and micro element content.

METHODThe dynamic change of Ca, Mg, Mn, Cu, Zn, B from Mabai, Matang, Gumu and Panlong were determined under different planting patterns (new soil, interval 5 years soil and continuous cropping soil).

RESULTAll the micro elements (except Ca, Mg) of interval 5 years soil and continuous cropping soil were significantly higher than those of new soil. All the middle and micro elements (except B) of interval 5 years soil were significantly higher than those of the continuous cropping soil. Planting patterns had remarkable influence on the content of Mn, Cu, B, but not Zn Ca, Mg. Cu, Ca under the 3 planting patterns, and Zn under the continuous cropping pattern did not show significant quarter changes. B content increased with the elongation of implantation time. Zn in new soil and interval 5 years also increased with prolonging of planted time. Mg, Mn and Cu content reached to peak value on April next year, and reached to minimum on the end of this experiment. Compared with new soil, the proportion of Mn, Cu in total elements increased by 29%, 114%, Mg, B decreased by 18%, 38%, Zn and Ca changed slightly of interval 5 years soils; In continuous cropping soil, Mn, Cu and B increased by 50%, 120%, 22%, respectively, but Zn, Ca, Mg had no significant change.

CONCLUSIONContinuous cropping pattern could not induce the deficient of soil middle and micro elements, and thereafter might not result in continuous cropping obstacles. But the imbalance proportional of soil middle and micro elements in P. notoginseng plant soils may be one of the main reasons for continuous cropping obstacles.
