Journal of Interventional Radiology 1994;0(04):-
Objective To evaluate the clinical value of selective salpingography (SSG) and fallopian tube recanalization (FTR) by home made coaxial catheter. Methods 116 cases of tube obstruction were diagnosed by hysterosalpingogram (HSG). SSG was performed with home made coaxial catheter. If proximal tube complete obstruction was still present, then followed by FTR. Results 116 cases of follow up showed 55 intrauterine pregnancies (IUPS) and 6 ectopic pregnancies. IUP rate was 47.4%. 28 of 116 cases were performed by HSG again, 25 of 28 cases were improved, effective rate was 89.3%.Conclusions SSG and FTR were a safe and effective procedure for the diagnosis and treatment of tube obstruction with home made coaxial catheter.

Objective To investigate the immune protection of dendritic cells(DCs) harboring kinase domain-containing receptor(KDR) fusion gene on mice carrying B16 melanoma.Methods The bone marrow precursor-derived dendritic cells(BMDCs) were induced from bone marrow progenitors of mice by GM-CSF.The KDR fusion gene mRNA was transfected into DCs in vitro.Mice were immunized with the same amount of DCs at 7-day interval and then each mouse was injected with 5?10~5 B16 cells.The mice without tumors were injected with B16 cells again 20 days later.Mice were randomly divided into 4 groups: group A(n=7),group B(n=8),group C(n=8) and group D(n=7).The mice were immunized with DCs one time in group A,2 times in group B,3 times in group C and as controls in group D.Results After one week,all mice in group D had tumors with average survival 15 days.All mice in group A,B and C had no tumors after 20 days later.After the second injection of B16 cells,2 mice in group A and 2 mice in group B had tumors.The mice in group C had no tumor.The average survival periods were calculated from first injection of B16 cells to the study end.The average survival period of group A was 50 days and that of group B was 72 days.Conclusions The dendritic cells vaccine harboring KDR fusion gene has immune protection against melanoma in mice.

Objective:To screen and identify differentially expressed long non-coding RNA (lncRNAs) in peripheral blood of children with sepsis, and to explore the role of lncRNAs in the pathogenesis of sepsis in children.Methods:The peripheral blood samples of 3 children with sepsis admitted to the ICU of Children′s Hospital of Capital Institute of Pediatrics from January to December 2016 and 3 healthy children who underwent physical examination in our hospital during the same period were selected, and the differential expression profiles of lncRNAs and mRNAs were screened by lncRNAs sequencing technology.The target genes of differentially expressed lncRNAs were predicted and the relationship pairs of lncRNA-mRNA related to F 1F O-ATPase activity were constructed according to the results of GO analysis.Further increasing the sample size, we verified the expression of some F 1F O-ATPase activity-related mRNAs and lncRNAs which were differentially expressed in the screening results by real-time fluorescent quantitative polymerase chain reaction(qRT-PCR). Results:Sequencing results showed that there were 252 lncRNAs with significant differential expression in peripheral blood of children with sepsis compared with healthy children, of which 86 were up-regulated and 166 were down-regulated; meanwhile, there were 2 652 mRNAs with significant differential expression, of which 955 were up-regulated and 1 697 were down-regulated.The results of qRT-PCR showed that the expression of lncRNA ENST00000621933.1, ENST00000616950.1 and ENST00000595748.1 in peripheral blood of children with sepsis increased( P<0.05), while the expression of MT-ATP8, ATP5E and ENST00000624705.1, ENST00000615535.1 in peripheral blood of children with sepsis decreased( P<0.05), which was consistent with the sequencing results. Conclusion:lncRNAs are differentially expressed in peripheral blood of children with sepsis compared with healthy children.The expression levels of lncRNA ENST00000621933.1, ENST00000616950.1, ENST00000595748.1, ENST00000624705.1 and ENST00000615535.1 which their target genes are MT-ATP8 and ATP5E may be related to the development of sepsis in children.

Objective:
To study the clinical characteristics of children with adenovirus pneumonia and provide evidence for clinical diagnosis and treatment timely.
Method:
This retrospective study included 89 children who were confirmed to have adenovirus pneumonia in hospital from January 2015 to December 2016. All the immunofluorescence test result of the 89 children showed that the exfoliated nasopharyngeal cells from the 89 children were all adenovirus antigen positive. All the severe type children reached the diagnostic criteria of severe pneumonia by the respiratory group in the society of pediatrics, Chinese Medical Association. The children were divided into 2 groups (severe type group and common type group). Different factors such as epidemiologic feature, clinical manifestation, laboratory examination and imaging data were analyzed.
Results:
Among the 89 pediatric patients, the male to female ratio was 1.5∶1. The ages ranged from 1 month to 14 years. Children under 5 years of age accounted for 96.6%(86/89). The incidence was 37.1%(33/89)in winter and 30.3%(27/89)in spring. The lengths of hospital stay were 3-48 days and the median length of stay was 8.25±4.75 days. All of these 89 cases had fever and cough. The proportion of severe adenovirus pneumonia was high among male, under 2 years of age, those with dyspnea, hepatosplenomegaly, tachycardia, leukocytosis, elevated C-reactive protein (CRP), PCT, myocardial enzymes, electrocardiogram abnormality and cluster shadow in chest CT. Differences were statistically significant (

OBJECTIVETo investigate the infection status and virulent genes of Aeromonas in patients with acute diarrhea in Pudong New Area, Shanghai.
METHODSIn 2012, stool samples were collected from diarrhea patients in 12 sentinel hospitals in Pudong for the detections of 13 pathogens causing diarrhea, and the detections of 5 diarrhea related virulent genes were conducted for Aeromonas isolates.
RESULTSA total of 101 patients were infected with Aeromonas in 2533 patients (4.0%). A total of 101 Aeromonas strains were isolated, including 17 Aeromonas hydrophila strains (18.8%), 44 Aeromonas veronii biovar sobria strains (52.5%) and 12 Aeromonas caviae strains (29.7%). And 44 coinfections with other pathogens were detected. Aeromonas infection mainly occurred in summer and in people aged ≥20 years. Among the patients infected with Aeromonas, 71 (70.3%) had watery diarrhea, 20 (19.8%) had vomiting and 11 (10.9%) had fever. Virulent genes detection showed that 95.0% of the Aeromonas. strains carried virulent genes, and the detection rates of hlyA, aerA, act, alt, and ast genes were 5.9%, 6.9%, 67.3%, 42.6% and 13.9%, respectively.
CONCLUSIONSHigh incidence of Aeromonas infection was found in the patients with acute diarrhea in Pudong, and a high proportion of coinfections with other pathogens was detected too. Most Aeromonas strains carried virulent genes, and the distribution varied.
