China donation after Citizen's death (CDCD) has been organized since 2010,and now has been synchronized with the international organ transplantation.At present,liver transplantation has become the only safe and curative treatment for the end-stage liver diseases.Nevertheless,there is much restriction over further exploration of this technique.This article will mainly focus on donation after brain death (DBD),and summarize the four dominating injuries of donor liver,including the donor's primary injury,cut and perfusion injury,graft preservation injury,and ischemia-reperfusion injury.

Objective To investigate the effect of the continuing quality improvement on PICC-related phlebitis in breast cancer patients undergoing chemotherapy. Methods Eighty breast cancer patients undergoing PICC for chemotherapy in our hospital from September to December 2014 were selected as control group, receiving routine nursing care. Another eighty patients undergoing PICC for chemotherapy from January to March in 2015 were selected as experiment group and the quality control cycle was used, the measures including investigating the present situation aiming to theme, goal setting and analyzing, working out and using countermeasures and effect comfirming. Result After applying continuing quality improvement in the experiment group the incidence rate of phlebitis in the continuing quality improvement group was significantly lower than those before continuing quality improvement and in the control group (P<0.05). Conclusion The implementation of continuing quality improvement activities can reduce the incidence of pzce-related phlebitis in patients with breast cancer during chemotherapy. It can improve the safety of PICC catheter and therefore, it is worthy of popularization.

Objective To study the role of emergency nursing professional team in the pre-hospital care.Methods Two hundred patients from October 2011 to March 2012 were set as the control group and another 200 patients from April 2012 to September 2012 were selected as the experiment group.The control group was managed by routine emergency mode and the experiment group by the emergency nursing professional team.The two groups were compared in terms of satisfaction degree,the time for the team to start and the rate of adverse nursing events.Results After establishing the emergency nursing professional team,the satisfaction degree was significantly increased,the time for the team to start was significantly shortened and the rate of adverse nursing events was significantly decreased(all P<0.05).Conclusion The management mode of emergency nursing professional team in pre-hospital medical care can effectively improve the quality of nursing care.

BACKGROUND: Many animal and clinical studies have reported that the safe and effective usage of umbilical cord blood-derived mesenchymal stem cells (UCB-MSCs) transplantation for treatment of neurological genetic diseases.OBJECTIVE: To investigate the feasibility and effect of UCB-MSCs transplantation in the treatment of spinal muscular atrophy (SMA).METHODS: A child admitted at January 2010 had been confirmed as having SMA, and drug and rehabilitation therapies were invalid. Then, the child received UCB-MSCs transplantation via the first intravenous infusion and three times of subarachnoid injection, once a week, (4-6)×107 cells once and four times as a course. Neurological physical examination, biochemical test, muscle enzymes detection, FIM scoring and electromyography (EMG) examination were conducted. RESULTS AND CONCLUSION: Compared with prior to transplantation, the level of muscle enzymes decreased, FIM scores were increased from 68 to 93 points, EMG results showed that the motor units with re-contraction in each 10.0 ms were increased that the motor function was improved, the lower extremity muscle strength elevated, and the self-care ability was improved in the SMA child at 6 months after transplantation. During the 10-month follow-up, the child had no adverse effects. It is indicated that UCB-MSCs transplantation is effective to treat SMA, and the neurological function has a remarkable restoration.

Objective: To provide references for quality evaluation of Lonicerea Japonicae Flos (LJF) through exploring correlation between color and contents of active ingredients of LJF in different development periods. Methods: The colorimeter was used to measure the color of LJF in different development periods; HPLC was applied to determine the contents of phenolic acids, flavonoids and iridoids. SPSS 17.0 software was used to analyze the correlation between color and chemical composition of LJF. Results: With the development of flower buds, the contents of phenolic acids, flavonoids compounds achieved the highest in two white stages and the contents of iridoids came to the highest in big white stage and silver flower stage. Therefore, only taking the consideration of the content of active ingredient, the best harvest time of LJF might be the big white stage. There was a significant positive correlation among contents of phenolic acids, flavonoids and brightness (L*) of LJF in different development periods, and there was a very significant negative correlation among contents of phenolic acids, flavonoids, iridoids, and browning index (BI). Conclusion: The color of LJF is closely related to the content of active ingredients, L* and BI can better link appearance and inner quality of LJF.

AIM: To evaluate the effects induced by topical antiglaucomatous drugs, Travoprost eyedrops on tear film.
METHODS: Eighteen patients ( 32 eyes ) with primary open-angle glaucoma or ocular hypertension were all treated with Travoprost eyedrops once every night. The symptom score, Schirmer's test ( S Ⅰ t ) , corneal fluorescein staining ( FL ) , tear film break - up time (BUT), were observed before the treatment and 1, 2 and 3mo after the treatment.
RESULTS: The average symptom score, FL of all patients were 1. 34 ± 1. 56 and 0. 44 ± 0. 73 before the treatment, and 2. 75±1. 63, 1. 08±0. 84; 5. 10±1. 68, 1. 53±0-67;6. 33±1. 40, 1. 98±0. 50 respectively after 1, 2 and 3mo of the treatment. There was significant increase in symptom score and FL after the treatment for 1, 2 and 3mo (P=0. 00). The average BUT, SⅠt of all patients were (7. 76±0. 92s), (8. 47±2. 73mm/5min) before the treatment, and (7. 08±1. 15s), (7. 73±3. 44mm/5min);(5-59±1. 33s), (6. 82±3. 05mm/5min); (4. 29±1. 87s), (6-04±3. 15mm/5min) respectively after 1, 2 and 3mo of the treatment. There was significant decrease in BUT and ST after the treatment for 1, 2 and 3mo (P=0. 00).
CONCLUSION: Travoprost eyedrops can obviously aggravate patients’ corneal irritation after treatment. Our results show abnormal decreased tear secretion and stability of tear film induced by Travoprost eyedrops over the short term.
