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 determine the efficacy of lifestyle interventions in adults with impaired glucose tolerance (IGT).Methods MEDLINE (Pub Med),EMBASE,Science Citation Index (SCI),and Cochrane Database were retrieved for articles about the relations of lifestyle intervention and IGT.Searches were limited to English language publications.The RCTs outcome evaluated in this study included 2 h plasma glucose level and fasting plasma glucose,meta-analysis was carried oat by Stata 11.0 among articles for the inclusion and exclusion criteria.The difference of effects was expressed as standardized mean deviation(SMD).Results A total of 10 RCTs studies met the inclusion criteria.Lifestyle interventions were associated with a decline in 2 h plasma glucose and fasting plasma glucose level (SMD =-0.67,P＜0.01 ;SMD =-0.33,P＜0.01),but high heterogeneity was identified in this meta-analysis.Conclusion Physical,dietary and both combined interventions can reduce 2-h plasma glucose and fasting plasma glucose levels in adults with impaired glucose tolerance.As high heterogeneity was identified in this meta-analysis,more high quality research is needed.

Objective To investigate the inhibitory effect of melatonin on the proliferation activity of murine foregastic carcinomac ( MFC) cells via melatonin membrane receptors MT 2 and its relationship with the signaling pathways of mitogen-activated protein kinases ( MAPKs), phosphatidylinositol 3-kinase ( PI3K)-Akt.Methods Using siRNA technology to silence MT2 expression, we examined the ability of melatonin to inhibit the proliferation activity of MFC cells and its influence on the phosphorylation of ERK 1/2 and Akt.Results We found two interesting effects of SiRNA-mediated silencing of MT2 expression.Firstly, it significantly antagonized the inhibitory effect of melatonin on the proliferation activity of MFC cells .Secondly , it partially blocked the inhibitory effect of melatonin on the phosphorylation of ERK 1/2 and Akt.Conclusion Our results suggest that melatonin can inhibit the phosphorylation of ERK 1/2 and Akt via MT2 receptors , thereby inhibiting the proliferation of gastric cancer cells .

Objective:To evaluate the effects of periodontal treatment with scaling and root planning supplemented with chlorhexidine on plasma lipids in patients with chronic periodontitis and hyperlipidemia(CPH).Methods:6 1 patients with CPH were randomly as-signed into control-treatment group(n=30)and intensive-treatment group(n=31).Patients in the control-treatment group underwent a standard cycle of supragingival mechanical scaling and polishing.Patients in the intensive-treatment group underwent the adjunctive full-mouth intensive removal of subgingival dental plaque biofilms with the use of scaling and root planning.Periodontal parameters,to-tal cholesterol(TC),triglycerides(TRG),high-density lipoprotein(HDL)and low-density lipoprotein(LDL)were measured before treatment and 2 and 6 months after treatment.Results:2 and 6 months after treatment,TRG was significantly lower in the intensive-treatment group than that in the control-treatment group(P<0.05),the levels of HDL were significantly higher(P<0.05);however, the levels of total cholesterol and LDL,in the intensive-treatment group were not significantly different from those in the control-treat-ment group 2 and 6 months after therapy.Conclusion:Intensive periodontal treatment may improve serum lipid levels in patients with hyperlipidemia and chronic periodontitis.

Objective To understand the undergraduate nursing students’ awareness of the basic situation of occupational exposure in Kunming Medical University, and to understand their knowing status of occupational exposure knowledge. Methods We used self- designed questionnaire to investigate 449 undergraduate nursing students in Kunming Medical University to obtain the status of occupational exposure and protection knowledge level of students.Results (1) 449 students were investigated, and 258 of them had been in clinical practice, and occupational exposure occurred in 48.8% of them. (2) Occupational exposure factors included grade, washing hands and wearing gloves;The results showed that:Grade was a risk factor and wearing glove and washing hands were protective factors. (3) There was relevance between accepting the occupational protection education and the occupational exposure. Conclusions A useful measure to reduce the occurrence of occupational exposure is Pre-service training for undergraduates nursing students. Operation should be in strict accordance with operating specifications. Schools and departments should implement occupational protection system, so as to strengthen the related knowledge vocational education,enhance self-protection awarenes,and reduce or minimize the occurrence of occupational exposure.
