Purpose To improve the comprehension of MR imaging features of hand-foot-mouth disease (HFMD).Materials and Methods The MRI findings of 5 cases of HFMD were retrospectively analyzed.Results The lesions in 4 cases were located in the junction of the pons and medulla oblongata, of which 1 lesion extended bilaterally at the same time. The lesion in the fifth case was located in dorsal pons. All lesions demonstrated patchy slight hyperintensity on T1WI and slight hypointensity on T2WI. These ill-circumscribed lesions showed hyperintensity on diffusion-weighted imaging. Conclusion HFMD possesses certain MR imaging characteristics, thus providing reliable imaging evidence for clinical diagnosis.

Objective To investigate the effect of Xingnaojing injection solution in treating severe burn patients with sepsis. Methods 41 cases of burn patients with sepsis were randomly divided into experimental group and control group. The experimental group were intravenously injected 40ml/day Xingnaojing injection solution for 7 days. The control group received routine therapy. Bacteria counts in burn wound, the survival rate of the patients and the positive rate of blood culture in the both groups were determined and compared. Results The experimental group had significantly lower bacteria counts in burn wound compared with the control group, and the negative blood culture rate and patient's survival rate in the experimental group were also obviously higher than those in the control group (P

AIM: To examine the 2′,5′-oligoadenylate synthetase activity and the peritoneal pathological changes when using commercially dialysates in order to reveal effects of the peritoneal dialysate biocompatibility on the immune function and morphological changes. METHODS: (1) CAPD animal models were made using dialysates. (2) Dynamic measurements of 2′,5′-oligoadenylate synthetase activity were made by paper chromatography. (3)The pathological changes of the peritoneal mesothelial cells were examined by light microscope. RESULTS: 2′,5′-oligoadenylate synthetase activities in both experimental (dialysis solution groups) and control group were increased and the mesothelial cell began to exfoliate and become thicker with the infiltration of inflammatory cells at different degrees in the experimental groups, while in the Baxter group, no active inflammation was observed. When the peritoneal dialysis stopped, activity of 2′,5′-oligoadenylate synthetase began to be normal in control group and continued to decline in experimental groups.CONCLUSION: Prolonged immune suppression existed with long-term peritoneal dialysis, causing pathological changes of the peritoneum at certain degrees. Different dialysis solutions resulted in different degrees of immuno-supression and peritoneal damages, which was relevant to the biological compatibility of the peritoneal dialysate.

Objective To investigate the apoptotic effect of the transmembrane form vaccine of human blood group A mimotope on malignant melanoma cell line B16. Methods B16 cells were transfected with different recombinant plasmid through Lipofectamine 2000 and incubated with different concentration of monoclonal anti-A antibody at 2.5 μg/ml, 5 μg/ml,10 μg/ml and 20 μg/ml. Apoptosis rate of cells was determined with Annexin Ⅴ/PI double staining by flow cytometry. Results Apoptosis rate to P/F-M-pIRES group B16 cells was 74.74% when anti-A monoclonal antibody concentration was 10 μg/ml; apoptosis rate of plasmids carrying peptide/Fas fusion gene such as P/F-M-pIRES group and P/F-pIRES group were significantly higher than M-pIRES group and pIRES group. The apoptosis rate was statistically significantly different between different recombinated plasmid groups (F＝669.707,P＜0.01). The apoptosis rate was statistically significantly different between different antibody groups (F＝106.596,P＜0.01). The interaction between recombinated plasmid groups and antibody groups was statistically significant (F＝34.806,P＜0.01). Conclusions The transmembrane form vaccine of human blood group A mimotope could induce B16 cell apoptosis in vitro. This vaccine may be a promising candidate for potential malignant melanoma therapy.

Objective:To investigate the effects of pregnancy and lactation nonylphenol (NP) exposure on the balance of Treg/Th17 cells in the brain of offspring mice and the related mechanisms.Methods:Thirty pregnant C57BL/6 mice were randomly divided into three groups: control group (drinking distilled water), and NP-treated groups (drinking 0.2 μg/ml or 2.0 μg/ml NP water solution). ELISA kit was used to analyze the levels of TNF-α, IFN-γ and IL-17, flow cytometry was used to analyze the frequency of Treg and Th17 cells in spleen, quantitative RT-PCR was used to analyze the RORγt, Foxp3 mRNA, Western blot was used to analyze the protein expression of RORγt, Foxp3 and PI3K/Akt/mTOR signal pathway, and immunofluorescence was used to analyze the expression of Iba1 in the brain tissue of offspring mice.Results:Compared with the control group, NP exposure increased the serum levels of IL-17 and TNF-α in male offspring mice ( P<0.05), and decreased the levels of IFN-γ( P<0.05). Flow cytometry analysis showed that the percentage of Th17 cells in the spleen of male offspring mice exposed to NP (0.2 μg/ml or 2.0 μg/ml) was significantly higher than that of the control group, while the percentage of Tregs cells was lower. Compared with the control group, the expression levels of Foxp3 proteins in the brain tissue of male offspring mice exposed to NP (0.2 μg/ml or 2.0 μg/ml) was significantly lower, accompanied by a dramatic increase in RORγt protein levels ( P<0.05). Similar mRNA expression was also observed in qRT-PCR analysis. The protein expression levels of mTOR (p-mTOR) and its upstream related regulators[PI3K, p-Akt (Ser473), p-Akt (Thr308)] in the brain of male offspring mice increased gradually during the period of exposure to NP( P<0.05). Immunofluorescence analysis showed that compared with the control group, the number of Iba1 positive cells in brain tissue of male offspring mice exposed to NP (0.2 μg/ml or 2.0 μg/ml) increased significantly ( P<0.05). Conclusions:Maternal exposure to NP during pregnancy and lactation may affect the development/function of neurons in offspring through neuroimmune axis, and increase the risk of neurodevelopmental disorders in offspring.

Objective To detect EPPB41L3 methylation frequency difference between esophageal squamous cell carcinoma (ESCC) tissues and the normal tissues and between ESCC patients′plasma and healthy volenteers′plasma, and to analyze the correlation with clinicopathological parameters. Methods We collected esophageal squamous cell carcinoma tissues (n = 42 patients) and adjacent surrounding normal tissues (n = 42 patients), and plasma from 42 patients with ESCC and from 50 healthy individuals. We used methylation specific PCR (MSP) combined with agarose gel electrophoresis to detect the methylation status of the EPB41L3. We used the SPSS 13.0 software for statistical analysis by χ2 test and Fisher′s exact test. Results EPB41L3 frequency of methylation was significantly higher in tumor tissues than in the adjacent tissues (59.5% vs. 4.8%), the difference was statistically significant (χ2 = 28.873, P < 0.001). For plasma, EPB41L3 methylation frequency was 31.0%in cancer patients, while was not detectable in the healthy volunteers. Methylation of EPB41L3 in tissues was more frequently found in patients with tumor size of ≥ 5 cm or T3 than in patients with tumor size of < 5 cm or T1-2. Conclusions The methylation frequency of EPB41L3 is higher in ESCC tissues than in control normal tissues, and higer in plasma from ESCC patients than that from the healthy volunteers. EPB41L3 methylation is more frequently found in patients with more advanced disease.
