Objective To study the diagnosis and treatment of the severe pulmonary infection in the patients after kidney transplantation. Methods The clinical data of 26 patients with severe pulmonary infection following kidney transplantation were analyzed retrospectively. Results Microorganisms were isolated and identified in 22 patients out of 26 kidney transplantation patients with severe pulmonary infection. The main etiological pathogens according to their frequency and type were: bacteria (15 cases, including Escherichia coli, Aerobacter cloacae, Klebsiella fredlanderi, Enterococcus faecalis, Staphylococcus epidermidis, etc.), fungi (12 cases, Fermentum, Blastomyces albicans, Candida tropicalis, Aspergillus, etc.), and cytomegalovirus (10 cases). 46.15% (12/26) of patients were infected with one kind of microorganism, and 53.85% (14/26) of patients were mixed infection. In 73.1% (19/26) of patients the pulmonary infection occurred during 1-6 months after renal transplantation. Among 26 patients, 12 developed ARDS, and 4 patients gave up therapies due to high expenses. With energetic treatment, 18 patients (81.82%) were cured and 4 died. Conclusions Intensive care and active measures should be given in the treatment of severe pulmonary infection after kidney transplantation. Early diagnosis, administration of broad-spectrum and combined use of antibiotics, the early identification of pathogens, enforcement in systemic support, including correction of immunosuppression, the timely use of mechanical ventilation to correct hypoxia, are the key treatment strategies for a successful result.

To investigate the change in renal CD11a and myeloperoxidase (MPO) contents and renal function during ischemia-reperfusion injury (IRI) of rat kidney, as well as the role of lymphocyte function associated antigen-1 (LFA-1) played in renal IRI, we utilized a rat model of renal IRI to detect the renal tissue contents of CDlla and MPO and renal functioa The results showed that the levels of CD11a and MPO were very low in normal renal tissue, but increased significantly in ischemia reperfusion. Renal failure was presented in rats with IRI. The levels in the ischemia-60min-reperfusion group were higher than those in the ischemia-30min-reperfusion group in the same time points. Our conclusion is the levels of CD11a and MPO in rat renal tissue increase significantly during renal IRI. LFA-1-mediated leukocyte adherence plays an important role in renal IRI. Up-regulation of CDlla further elucidates the mechanism of relation between IRI and acute rejection: more heavier IRI is, more possible acute rejection would be.

AIM: To determine the role of the glycocalyx in microvascular permeability. METHODS: Dextran was intravenously injected and quatitatively examined in the rat transient cerebral ischemic model. At the same time, endothelial glycocalyx (anionic sites) was labelled with the probe cationic gold colloid (CGC) using post-embedding technique and examined with electron microscope. RESULTS: The labeling of CGC decreased significantly following ischemia, meanwhile, microvascular permeability to dextran increased. CONCLUSION:Endothelial glycocalyx is very sensitive to ischemia or anoxia. Its disruption may be the initiator of the dysfunction of endothelium and the determinant of increased permeability.

Objective To compare the CT findings of different phases in pediatric hepatoblastoma (HB) based on PRETEXT system in order to optimize pediatric HB CT scan protocol. Methods A total of 58 HB patients who were surgical and pathological diagnosed from January 2015 to December 2016 were analyzed. Pre-operation CT exams were analyzed respectively. Observing items included tumor size, intra-abdominal invasion, bleeding, intrahepatic metastasis, lymphatic metastasis, metastasis (except lymphatic in abdomen) main portal vein, three main hepatic vein, inferior vena cava (IVC) invasion, para-tumor hepatic arteries, and its branches. All image findings were compared to pathological and surgical findings to calculate the agreement rate. Exact Fisher test and R × C χ2 test were used. Results According to the surgery and pathological results, the agreement rate of tumor size was n=40 (68.9%) at non-contrast phase, n=43 (74.1%) at artery phase and n=52 (91.2%) at venous phase. Venous phase was adaptive for observing tumor size (χ2=8.16,P=0.018). For main portal vein, three main hepatic vein, and IVC invasion, none was found at both non-contrast and artery phase. N=12 (20.7%, P<0.001) was found at venous phase. For para-tumor hepatic arteries, and its branches, none was found at non-contrast phase. N=46 (79.3%) was found at artery phase. N=17 (29.3%) was found at venous phase. Artery phase was adaptive for observing (P<0.001). There was no statistical significant difference in intrahepatic metastasis, lymphatic metastasis and metastasis. Conclusions Suspected pediatric HB, artery and venous phase CT scan would meet the clinical requirement, there was no need for non-contrast pahse. Follow up cases, a single venous phase was enough. Venous phase contributed much more information on tumor size and high risk prognosis evaluation.
