BACKGROUND:It is an important and complex issue for the incidence of bacterial infection and complications after transplantation. The monitoring and care after transplantation can improve the success rate of transplantation. OBJECTIVE:To search the database of China National Knowledge Infrastructure, North American Clinical Trial Register and Thomson Reuters Web of Science database, and to perform literature metrological analysis and clinical trials registration project analysis on the published literatures of the monitoring and care after transplantation. METHODS:A total of 138 literatures were searched with the key words of“intensive care, transplantation”in the database of China National Knowledge Infrastructure on the intensive care after transplantation. 23 literatures were used for further analysis by reading titles and abstracts and 115 papers were excluded; the Thomson Reuters Web of Science database was searched with the key words of“intensive care, transplantation”for the literatures on the intensive care after transplantation published from 2008 to 2013;the North American Clinical Trial Register was searched with the key words of“intensive care, transplantation”for the related clinical trials, and a total of 50 registered projects were obtained, only 10 interventional studies. RESUTLS AND CONCLUSION:In recent years, the literatures on the intensive care after transplantation show a gradual increase trend. Compared with international research, fewer researches in this field emerge in China, literature quantity and quality need to be improved. There have been 1 693 papers published in the Thomson Reuters Web of Science database regarding the intensive care after transplantation. United States published the most literatures than other countries, total 532 papers, accounting for the largest proportion, 31.424%of total literatures. Transplantation Proceeding published the most literatures, total 144 papers, accounting for 8.506%of total literatures. There are 50 clinical trial registration projects related to the intensive care after transplantation in the North American Clinical Trial Register, 10 of them were interventional study, accounting for the majority, fol owed by observational study. Diagnostic study had no related registration projects. The surgery of transplantation was complex with trauma. The early monitoring and care post-transplantation are directly related to the success of surgery. Strengthening the monitoring and care of patients’ vital signs, rejection, bacterial infections and other aspects can reduce the complications and improve patients survival rate and quality of life.

Positron emission tomography-computed tomography (PET-CT) plays an important role in the diagnosis and treatment of liver cancer.18F-FDG PET-CT imaging-positive rate is low due to a variety of factors affecting the hepatoma cells.But the joint imaging can significantly improve the diagnostic positive rate and provide the basic information for treatment selection and prognosis.PET-CT is better than conventional imaging techniques in the diagnosis and therapy monitoring for metastatic liver cancer.

AIM: To observe the effect of adrenocorticotropic hormone(ACTH) on the levels of brain-derived neurotrophic factor (BDNF), trkB and corticotropin-releasing hormone(CRH) in the hippocampus of arthritic rats.METHODS: The BDNF immunoreactivity (IR) and CRH-positive neurons were stained with immunohistochemistry and in situ hybridization methods, respectively.RESULTS: The BDNF-IR, CRH mRNA-positive neurons in the contralateral hippocampus of the arthritic rats were increased significantly, which was decreased markedly by intraperitoneal injection of ACTH. However, the effect of ACTH was attenuated after adrenalectomy (ADX).CONCLUSION: These results suggest that BDNF and CRH in the hippocampus of arthritic rats were involved in the modulation of chronic pain, ACTH produced its analgesic effect by inhibiting the increase in BDNF and CRF level. Adrenal is critical to the analgesic action of ACTH.

Objective To study the signification of p57kip2 immunostaining to distinguish molar gestations from hydropic abortions.Methods To observe the p57kip2 immunohistochemical expression in 58 cases of histological hydropic villi which were divided into complete mole(18 cases) ,partial mole(19 cases),hydropic abortion(11 cases)and undetermined hydropic abortion or molar gestations(10 cases) and in 3 normal placentas.Results Normal villi,partial mole and hydropic abortions show positive staining for p57kip2, which expressed in the nuclei of cytotrophoblast and villous mesenchyme,and complete moles show complete absence of staining in the cytotrophoblast and villous mesenchyme.According to the comparison of the diagnosis based on morphology and the one based on p57kip2 stai-ning,the later whose sensitivity is 96% (46/48) confirmed the earlier diagnosis in 58 cases studied and the later conformed to the earlier very well.Conclusion The immunohistochemical staining for p57kip2 is a valuable diagnostic mean to distinguish molar gestations from hydropic abortions and is a sensitive and specific marker for the diagnosis of complete mole.

Objective To explore the potential role of monocyte chemotactic protein-1 ( MCP-1 ) gene in the pathogenesis of acute lung injury (ALI) in early acute necrotizing pancreatitis (ANP). Methods Forty SD rats were randomly divided into control group, ANP 3, 6, 12 h group with 10 rats in each group according to a number table. ANP was induced by intraperitoneal injection of 15% L-arginine solution at a dose of 2.0 mg/g body weight. Pathological changes of pancreases and lungs were observed. Lung wet/dry weight ratio was measured. Intrapulmonary expression of MCP-1 mRNA was evaluated by RT-PCR. Results After intraperitoneal injection of 15% L-arginine solution, the rat's pancreas presented with bleeding, necrosis comparable with pathological changes of ANP. Pulmonary tissue edema was obvious. At ANP 3, 6, 12 h group, the pathological scores of the lung were 3.75±0.58,5.50 ±0.63,5.86 ±0.54, the wet/dry weight ratios were 4.85 ±0.38,4.97 ± 0.47,5.03 ± 0. 46, the MCP-1 mRNA expressions were 0.36 ± 0.08, 0. 56 ± 0. 15, 0. 72 ± 0.21,which were significantly higher than those in the control group (0.12 ±0.05,4.32 ±0.33,0.21 ±0.05, P＜0.05 or ＜0.01 ). The MCP-1 mRNA expression in lungs was significantly correlated with the degree of lung damage and wet/dry weight ratio of lungs (r=0.75,r=0.89,P＜0.05).Conclusions MCP-1 mRNA expression was up-regulated in the early phase of ANP in the lungs, and it may play an important role in ALI during ANP.

Objective Analyzing the regional distribution discrepancy of medical and health resources in China,with the purpose of providing the government with policy making evidences for optimizing medical and health resource allocation.Results Dividing China into three regions based on regional economic development and geographic setting,and selecting 6 indicators for medical and health resources.On the basis of the statistics of 31 provinces released by the state in 2009,analyzing the interprovincial disparities of the distribution of these six resources,by means of the coefficient of variation,Gini coefficient and Theil index.Methods The largest inter-regional allocation disparity is found in the number of biopharmaceutical manufacturing companies per ten thousand population.And the smallest discrepancy is found in the number of hospital beds among these regions.The top two extreme differences of resource possession per ten thousand population between the maximum and the minmum region are the number of biopharmaceutical manufacturing companies and tertiary hospitals.The eastern region is the largest contributor to the discrepancy of allocation for the six resources within and between regions.The less developed regions contribute the most inter-regional discrepancy for the allocation of medical practitioners(their assistants included),hospital beds,tertiary hospitals and pharmaceutical companies.And the developed regions contribute the most inter-regional discrepancy of medical finance support from local governments and the most of the allocation of biopharmaceutical manufacturing companies.In general,regions of higher development enjoy greater possession of the SIX resources per population in such regions. But these two are not always in direct proportion. Condnsion Regional distribution disparity of the six resources is not yetreasonable in China.To better meet the health needs of the population in various regions,the government is expected to increase its financial support for building biopharmaceutical manufacturing companies and tertiary hospitals in the less developed western regions,to better use resources of developed regions,and to keep off investments at low level and repetition.The government is also recommended to pay attention to the proportion of government health finance output and the quality and quantity of medical practitioners.

Objective　To investigate the expression of LPS receptor-CD14(CD14) on the membrane of Kupffer′s cells (KCs) induced by Lipopolysaccharide (LPS )and its role in activation of KCs and production of cytokines. Methods　KCs were isolated by collagenase perfused Wistar rats and routinely cultured in 24-well dishes for 12 h. Cells were harvested and adjusted to a concentration of 1×106/ml/well and were devided into two groups. Group of LPS: KCs were induced with different concentration of LPS (0, 100 ng/ml, 1 μg/ml and 100 μg/ml). Group of PI-PLC: KCs were pre-incubated for 30 min with one unit of phophatidy linositol specific phospholipase C (PI-PLC) before different concentrations of LPS were added. KCs were cultured for 30 and 60 min respectively. Supernatants were then collected for measuring the level of TNFα and IL-6. Cells were stained by indirect immunofluorescent method ( rabbit anti-CD14 antibody and goat anti-rabbit IgG conjugated with FITC ) and analyzed with flow cytometer (FCM). The percentage and mean fluorescence intensity (FI) of CD14-positive cells were taken as the indexes. Results　In LPS group, after incubation of cells with increasing concentration of LPS, a significant increase in the percentage of CD14 positive KCs were found and the mean FI was stronger when compared with the control points or the group of PI-PLC. The levels of TNFα and IL-6 in supernatant also increased (P<0.01). In group of PI-PLC, decreased percentage of CD14 positive KCs and weakened mean FI were found when compared with group of LPS. The increasing production of TNFα and IL-6 slowed down in the group of PI-PLC. Conclusion　CD14 expression of KCs might be up-regulated by LPS with increase of some cytokines. The production of cytokines in KCs induced by LPS is partially inhibited by PI-PLC.

ObjectiveTo investigate the protective effects of p38MAPK inhibitor SB203580 on acute necrotizing pancreatitis associated lung injuries in rats.Methods Fifty-four SD male rates were randomly divided into 3 groups,including control group,ANP group,SB203580 group with 18 rats in each group.ANP was induced by intraperitoneal injection of L-arginine solution. Rats in control group were intraperitoneally injected with same amount of saline.Before ANP induction,the rats in SB203580 group received 10 μmol/L SB203580 dissolved by dimethyl sulfoxide at a dose of 5mg/kg weight via intraperitoneal injection.The rats were sacrificed at 3,6,and 12 h after operation,the serum levels of amylase,TNF-α,IL-6 was determined.Pathological changes of pancreas and lung were observed.The wet/dry (W/D) weight ratio of lung and MPO were measured.CINC mRNA of lungs was determined by RT PCR. Expression of phosphated-p38MAPK (p-p38MAPK) protein was evaluated by Western blotting.ResultsThe serum levels of amylase,TNF-α,IL-6and wet/dry (W/D) weight ratio of lung,MPO activity,CINC mRNA and p-p38MAPK protein expression of lungs were (1035 ±73)U/L,(0.94 ±0.16)μg/L,(4.77 ±0.86) μg/L,3.92 ±0.29,(0.39 ±0.02)U/g,0.28 ±0.04,0.09 ±0.04 in control group at 6 h after operation,and the corresponding values were (5848 ±656) U/L,(3.84 ±0.32)μg/L,(103.54 ± 15.32)μg/L,4.97 ±0.47,(1.03 ±0.08) U/g,0.62 ±0.06,0.52 ±0.14 in ANP group,while they were (4259 ±286) U/L,( 1.64 ±0.21 ) μg/L,(76.56 ± 11.46) μg/L,4.32 ±0.34,(0.78 ±0.05)U/g,0.37 ±0.04,0.27 ±0.08 in SB203580 group.The values in ANP group were significantly higher than those in control group,and the values in SB203580 group were significantly lower than those in ANP group,but they were still significantly higher than those in control group ( P ＜ 0.01 ).ConclusionsSB203580 may attenuate injury of lung and pancreas in ANP by blocking p38MAPK signal transduction pathway,and decreasing the production of inflammatory cytokines.
