The ethical problems had directly affected the applying and development of organ transplantation.The serious shortage of donors restricted this technique deeply.The analysis on the ethical and moral problem about organ transplantation had been performed from ethical angel.It was proposed that implementation of brain-death legislation,setting up the newly ethical conception and prohibiting the organ business.Voluntary contribution was the first ethical principle in the source of the donor.Medical principles and social standards should be taken into account on the problem of acceptor selection.

Objective To clarify the role of hypothalamic IL-6 in gastric mucosal blood flow, gastric juice pH value and gastric mucosal injury. Method Model of gastric stress ulcer was established by fluid percussion to make craniocerebral trauma. Twenty male SD rats fed for one week in the experiment room were randomly(random number) divided into control group, one hour group, six hours group and 12 hours group after injury. The levels and distribution of IL-6 in hypothalamus were detected by using immunohistochemistry and Western blot. Simultaneously, gastric pH value, gastric mucosal blood flow and gastric mucosal injury index of rats in each group were measured, and the histology of gastric mucosa was observed. Results IL-6 immunoreactive cells were widely distributed in neuronal cells of hypothalamus of the stressed rats especially in the para-ventricular nucleus (PVN).One hour after injury, the pH value rapidly declined, and the lowest point appeared 6 hours later. One hour after injury, the injury of gastric mucosa was found, and the injury became worse and worse as time got longer and longer. The ulcer index (UI) was increased. One hour after injury, there was a brief increase in blood flow to the peak in gastric mucosa, and then the blood flow declined until 6 hours elapsed and got stable. The experiment prompted the gastric stress ulcer appeared. Conclusions In the SD rats with gastric stress ulcer induced by craniocerebral injury incurred by hydraulic percussion, the hypothalamic IL-6 may activate neuronendocrine metabolism mediated through the activation of PVN, inducing gastric mucosal injury.

Objective To observe the safety and efficacy of enteral nutrition (EN) in patients with hepatic dysfunction in early postoperative period. Methods A total of 52 patients with hepatic dysfunction were divided randomly into EN ( n =26) and PN ( n =26) groups. Patients in the two groups received EN and PN at 6 h after operation, respectively. The changes of hepatic function and conditions of nutrition were measured. The complications and the changes of gastrointestinal function were observed. The time of hospitalization after operation and cost of nutrition were also recorded. Results The level of bilirubin descended faster in EN than that in PN. Both EN and PN could improve the nitrogen balance. The recovery of gastrointestinal function in EN was much earlier than that in PN ( P

BACKGROUND: von Willebrand factor (vWF) is only released from endothelial cells and platelets and is an in vivo and in vitro marker of endothelial injury in septic patients with acute lung injury (ALI). Interleukin-8 (IL-8), as a proinflammatory mediator causing recruitment of inflammatory cells, induces an increase in oxidant stress mediators and makes it as a key parameter for localized inflammation. However, it has not been well established whether the level of serum IL-8 is associated with the severity of lung injury and whether it is a prognosis marker for severe lung contusion. This study was to investigate the expression of plasma vWF and IL-8 and their association with the severity and outcomes of severe pulmonary contusion. METHODS: A total of 63 patients were divided into a severe pulmonary contusion with acute respiratory distress syndrome (ARDS) group and a non-ARDS group, or a survivor group and a non-survivor group, or an injury severity score (ISS) <20 group and an ISS ≥20 group. Another 20 healthy volunteers served as controls. The levels of plasma vWF and serum IL-8 were measured by enzyme-linked immunosorbent assay (ELISA) at 1, 3, 5 and 7 days after injury. The expression patterns of the plasma vWF and serum IL-8 were compared between different groups. RESULTS: The concentrations of plasma vWF and serum IL-8 were significantly increased in all severe pulmonary contusion patients at all time points in comparison with the control group. The concentrations of plasma vWF in patients with ARDS increased during the whole study period, but vWF in patients with non-ARDS increased gradually until day 5 and then decreased at day 7. The concentration of serum IL-8 showed a similar expression pattern in both groups, but the expression increased more significantly in the ARDS group than in the non-ARDS group. Interestingly, both plasma vWF and serum IL-8 levels steadily increased in the non-survivor group. Furthermore, the level of plasma vWF was higher in the ISS≥20 group than in the ISS<20 group. The level of serum IL-8 in the ISS≥20 group was consistently high, while that in the ISS<20 group peaked at day 3 and decreased at day 5. In addition, the level of plasma vWF was positively correlated with platelet count, but negatively correlated with oxygen index. The level of serum IL-8 was positively correlated with white blood cell count and ISS score, and inversely correlated with oxygen index. CONCLUSION: The elevated levels of plasma vWF and serum IL-8 in severe pulmonary contusion patients reflect the severity of pulmonary injury and patients outcomes, suggesting that the plasma vWF and serum IL-8 are sensitive markers for clinical evaluation of the severity of pulmonary injury and predication of patient prognosis.

Background and purpose: L-asparaginase (L-Asp) is an important drug in the treatment of childhood lymphoid neoplasms at present, but a lot of adverse reactions of L-Asp were observed. Pegasparaginase (PEG-Asp) is available in China in recent years. This study aimed to explore efifcacy and side-effect of PEG-Asp as ifrst-line treatment in childhood acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL). Methods:A total number of 211 ALL or LBL patients were treated with CCLG 2008 or BFM-90 protocol with PEG-Asp or L-Asp between Apr. 2008 and Mar. 2013;42 patients, among whom, were 35 ALL patients and 7 LBL patients, were treated with PEG-Asp as ifrst-line treatment;169 patients were treated with L-Asp as ifrst-line treatment (including 53 patients treated with L-Asp during induction protocol; with PEG-Asp during consolidate protocol). The clinical outcome and adverse reaction of PEG-Asp with L-Asp were observe and compared. Results: There were 35 ALL patients in PEG-Asp ifrst-line treatment group and the complete remission rate after 1 course of PEG-Asp was 97.1%,however, which was 83.3%of high risk ALL patients. The complete remission rate of 7 LBL patients of PEG-Asp ifrst-line treatment group was 57.1%. There was no signiifcant difference between 2 groups (P>0.05). Thirty-four patients relapsed including 5 patients of PEG-Asp ifrst-line treatment group, 16 patients of L-Asp ifrst-line treatment group and 13 patients treated with L-Asp during induction protocol and with PEG-Asp during consolidate protocol. Thirty-one patients died including 3, 18, 10 patients in 3 groups respectively. Twenty-two patients died of relapse, 4 died without remission, 5 died of complications. There was also no signiifcant difference between 2 groups (P>0.05). The incidence rates of adverse reactions were 47.6% and 63.3% respectively. Anaphylaxis, liver functions abnormalities, blood coagulation abnormalities, gastrointestinal reaction, hyperglycemia and pancreatitis were common in our patients. The incidence rate of anaphylaxis in PEG-Asp as ifrst-line treatment group was lower than other groups (P=0.03). But there was no signiifcant difference been observed in the incidence of other adverse reaction. Conclusion: The short-term efifcacy of PEG-Asp as the ifrst-line treatment in childhood leukemia and lymphoma was satisfactory and the incidence rate of anaphylaxis was lower. However, we will still pay much attention to adverse reaction monitoring of PEG-Asp.

To explore a sensitive , stable and handleable method for evaluating phagocytosis of mouse peritoneal macrophages by flow cytometry , and get a set of optimized solutions.Methods: The peritoneal macrophages obtained from ICR mice were divided into two part.One part was used directly ,and another part was 1∶1 diluted.Three fluorescent microsphere concentrations were used (5×106/well,1×107/well and 1.5×107/well).Incubation time were respective 1 h,1.5 h and 2 h.The adherent cells were digested by enzyme or cell scraper.The percentage of phagocytic cells ( PP) and the phagocytic index ( PI) were determined by flow cy-tometry.To verify and confirm the reliability of experiment conditions , effect of JKS on phagocytosis of mouse macrophages were evaluated with flow cytometric assays and chicken red blood-cell method.Results:The higher concentration of fluorescent microspheres meant PP and PI were higher.When cell concentration was 1×105-2×105 ml-1 ,incubation time was 1.5 h,concentration of fluorescent microspheres was 1.5 ×107/well,the PP and PI were the highest (89.87%,1.54).When incubation time was 2 h,the PP and PI declined(57.71%,1.51).Effect of cell concentration on the PP and PI were negatively correlated with fluorescent microspheres .After adherent macrophages were digested by trypsin+EDTA,the PP and PI were 44.51%,0.68.The PP and PI were 37.92%,0.57 after di-gestion by EDTA.The results were lower than using cell scraper.The PP(1 485 mg/kg group) of JKS were higher than control group that were evaluated with flow cytometric assays and chicken red blood-cell method.The difference was statistically significant ( P<0.05 ).Conclusion: These are the optimized solutions for the experiment such as the concentration of peritoneal macrophaes is (1-2)×105,the incubation time is 1 h and the concentration of fluorescent microspheres is 1×107/well.

AIM:To observe the effect of buyanghuanwu decoction,a Chinese medicine,on the expression of AMPA receptor GluR1 subunit in mRNA and protein levels in rat hippocampus with vascular dementia (VD). METH-ODS:One hundred and forty -four rats were randomly divided into 4 groups:shamoperation group,VD model group,nimodipine group and buyanghuanwu decoction treatment group. The rat model of VD was built up by the method of 4 vessel occlusion. The VD rats were intragastrically treated with buyanghuanwu decoction suspension (pharmacognostic 50 g. kg -1.d -1) and nimodipine suspension (20 mg?kg -1.d-1) for 30 d. The learning and memory abilities were evaluated by Morris water maze testing. The change of GluR1 protein in hippocampal neurons in each group of rats was measured with immunohistochemistry and Western blotting techniques. The expression of GluR1 mRNA in hippocampus was determined by real -time fluorescence quantitative PCR. RESULTS:Compared to sham -operation group,the average escaping latency period (s) of Water maze tests in VD rats prolonged significantly and crossplatform time (numbers/min) shortened distinctly (P 0. 05). Compared to the rats in shamoperation group,the mRNA and protein levels of GluR1 were apparent-ly decreased in VD rats (P 0. 05). CONCLUSION:Buyanghuanwu decoction improves the learning and memory abilities in VD rats. The therapeutic mechanism is associated with lessening the neuron injury on CA1 field in hippocampus and restoring the mRNA and protein ex-pression of GluR1.
