Objective:This study aims to analyze the differences in the alternative splicing pattern of ADAR2 among glioma cell lines U87, U251, A172, and normal human astrocyte HA1800. Methods:A-to-I editing level at the Q/R-Site of GluR-2 was analyzed by RT-PCR and sequencing. Real-time PCR was performed to detect the expression level of each alternatively splicing variant using a specific primer that was confirmed to amplify only the targeted template and not other alternatively spliced variant fragments. Results:We verified that the Q/R-Site of GluR-2 is under-edited in glioma cell lines. Real-time PCR revealed that the ADAR2 pre-mRNA splic-ing pattern has no significant difference at exons 1a and 2 between glioma cell lines and normal human astrocyte. We also detected that the amount of alternative splicing variants, including exon 5a, was higher than that of alternative splicing variants not including exon 5a in human glioma cell lines. However, the expression of alternative splicing variants, including exon 5a, was lower than that of alterna-tive splicing variants not including exon 5a in human astrocyte. Conclusion:Evident differences in splicing were observed at the site of exon 5a between glioma cell lines and normal human astrocytes. The difference in the alternatively splicing pattern at exon 5a may be attributed to the decreased activity of ADAR2.

ObjectiveTo analyze the clinical characteristic of the nasal type extranodal NK/T cell lymphoma(ENKL)as well as the therapeutic effects for different treatment methods and element that would affect prognosis.MethodsReview and analyze the 27 patients with pathologically confirmed ENKL patients received radiotherapy (3 cases),chemotherapy (9 cases),combination of radiotherapy and chemotherapy (15 cases),3 of whom received auto-HSCT.Detailed B symptoms,lactate dehydrogenase (LDH),performance status(PS)scores,international prognostic index(IPI),Ann Arbor stage and therapeutic modality were included in univariate analysis.ResultsThe average overall survival time was 32 (2-42) months.The 1,2and 3 year overall survival (OS) rates were 79.5 ％,71.6 ％,53.7 ％,respectively.The 2-year overall survival of patients who was early stage (stage Ⅰ + Ⅱ ) was 83.3 ％,and those who was advanced stage(stage Ⅲ+Ⅳ) was 62.3 ％ (P =0.368).Among the patients in early stage,after radiotherapy or chemotherapy,4 cases achieved OR (overall response) which is complete remission (CR) or partial remission (PR),9/10 in combination of radiotherapy and chemotherapy achieved OR. While among those in their advantage stage,the OR in chemotherapy is 2 cases,2/5 in combination of radiotherapy and chemotherapy.In univariate analysis,age and short-term response were main factors of survival(P ＜0.05).ConclusionTo treat the nasal ENKL in the early stage,radiotherapy can achieve a better effect,while combination of radiotherapy and chemotherapy is an important method for patients in advantage stage.Age and short-term response may be.prognostic factors of nasal type ENKL.

Objective To investigate the methods of reducing radiation dose in CT coronary angiography through optimizing individualized scan dosage protocol.Methods Two hundred patients (group A)underwent coronary CTA examination which was performed with fixed 120 kV and variable mA according to their BMI.The mA was set as 150-300 mA(BMI ＜ 18.5 kg/m2),300-500 mA (18.5 kg/m2 ≤ BMI ＜ 25.0 kg/m2),and 500-800 mA(BMI ≥ 25.0 kg/m2).When all examinations were finished,a linear regression was employed to analyze the correlation between mA and BMI,body surface(Suf),image noise(SD)respectively.The results of the analysis were used to formulate a regression equation,which was further used to establish a table list for quick search on how much mA that individualized coronary CTA scan would need.Another 200 patients(group B)enrolled for the individualized scan were scanned under new protocol that previous study established.The tube voltage was 100 and 120 kV.The tube current was variable according to the data in the table list.One-way ANOVA and Kruskal-wallis H test were used for statistics.Results Regression equation between mA and BMI,Suf,SD was:mA =17.984 × BMI + 169.149 × Suf-2.282 × SD-361.039.The SD(group A:32.08 ± 5.80,group B:28.60±4.47),dose index volume(CTDIvol)[group A:(41.97 ± 11.37)mGy,group B:(33.18±10.07)mGy],effective dose(ED)[group A:(10.91 ±3.07)mSy,group B:(8.83 ±2.72)mSv]had significant differences between the two groups(F =43.45,63.71,49.07 respectively,P ＜0.01 for all).The SD and ED results obtained in group B were better than those in group A.Conclusion Better performances were obtained when BMI combined Suf was used as a new individualized protocol than when BMI was used only,which means good image quality and lower radiation dosage in coronary CTA examination.

Objective To evaluate the effect of sevoflurane anesthesia on activation of gliocytes in aged rat hippocampi.Methods One hundred and four male Wistar rats,weighing 600-650 g,were randomly divided into 2 groups (n =52 each) using a random number table:control group (group C) and sevoflurane group (group S).Group S inhaled 3.6％ sevoflurane for 2 h,and open reduction and internal fixation was performed after tibial fracture was induced.Y-maze test and fear conditioning test were carried out on days 1,3 and 7 after surgery.Six rats of each group were chosen on days 1,3 and 7 after surgery and hippocampi were removed to detect the activation of microglias and astrocytes (by immunofluorescence) and expression of interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) (by Western blot).Results Compared with group C,the number of entries into each arm was significantly reduced,the duration of N arm stay was shortened,the percentage of time spent freezing induced by condition and the percentage of time spent freezing induced by context were decreased,and the activation of microglias and astrocytes was increased,and the expression of IL-6 and TNF-α was up-regulated in S groups (P ＜ 0.05).Conclusion Sevoflurane-induced postoperative cognitive dysfunction may be related to enhanced activation of gliocytes in aged rat hippocampi.

Objective To investigate the protective effects of lentivirus mediated Bcl-2-associated athanogene 1L (BAG-1L) over-expression on human neuroblastoma cells (SH-SYSY) induced by hypoxia/re-oxygenation,and to study its effect on the phosphoinositide 3 kinase serine/threonine protein kinase (PI3K/AKT) pathway.Methods SH-SYSY cells were cultured in vitro,and the cells at logarithmic phase were collected,and they were divided into recombined lentiviral infection group [infected by lentivirus containing BAG-1L and green fluorescent protein (GFP) gene],vector control group (infected by lentivirus containing GFP without BAG-1L gene) and cell control group (non-infection).Western Blot was used to detect the expression of BAG-1L in target cells after infection for 48 hours.SH-SY5Y cells were subjected to hypoxia for 8 hours and re-oxygenation for 24 hours,then the cell counting kit-8(CCK-8) was used to detect the cell activity,and the apoptosis was detected by flow cytometry after allophycocyanin labeled annexin V/7-amino actinomycin D (Annexin V-APC/7-AAD) staining.Western Blot was used to detect the protein expressions of BAG-1L,heat shock protein 70 (HSP70),AKT and phosphorylated AKT (p-AKT).Results After infection for 48 hours,exogenous BAG-1L protein bands were observed in recombined lentiviral infection group,but not observed in cell control group and vector control group.After hypoxia/re-oxygenation treatment,the cell viability in recombined lentiviral infection group was significantly higher than that in cell control group and vector control group (A value:0.689 ± 0.036 vs.0.425 ± 0.013,0.400 ± 0.012),apoptosis was significantly decreased [apoptosis rate:(26.97 ± 1.82)％ vs.(36.60± 1.45)％,(35.77 ± 3.74)％],the protein levels of BAG-1L,HSP70 and p-AKT were significantly increased [BAG-1L protein (gray value):2.405 ± 0.167 vs.0.529 ± 0.141,0.601 ± 0.099;HSP70protein (gray value):0.997±0.123 vs.0.634±0.091,0.584±0.106;p-AKT protein (gray value):1.234±0.118 vs.0.661 ± 0.210,0.712 ± 0.199,all P ＜ 0.01],but the protein level of AKT was slightly increased (gray value:1.103 ± 0.269vs.0.646 ± 0.188,0.791 ± 0.326) without statistically significant differences (both P ＞ 0.05).There was no significant difference in all parameters between cell control group and vector control group (all P ＞ 0.05).Conclusion Lentivirus mediated BAG-1L gene over-expression can protect nerve cells against hypoxic injury and apoptosis,and the protective effect may be related to the activation increase of pathway on PI3K/AKT.

Objective To analyze the incidence and risk factors of de novo hepatitis B virus (HBV) infection from anti-HBc-positive donors in pediatric living donor liver transplantation and to explore the diagnosis and treatment.Method A retrospective analysis was conducted on 105 cases of pediatric living donor liver transplantaions (LT) perfomed during September 2006 to December 2013.HBV markers,including hepatitis B surface antigen (HBsAg) and antibody (anti-HBs),anti-HBc,hepatitis B e antigen (HBeAg) and antibody (anti-HBe) were determined in both donors and recipients before LT and in recipients after LT.HBV DNA titer was measured if the recipients were strongly suspected of de novo HBV infection.Result After 4 perioperative deaths were excluded,101 cases were studied.The median follow-up period of all the patients was 20.5 months (2.7-97.7 months).de novo HBV infection occurred in 6 of 101 recipients (5.9％) 3.5 18 months after LT.Forty-four (43.6％) of the children received HBcAb-positive allografts,and 11.4％ (5/44) of the children were had de novo hepatitis B infection.All five of the HBV-infected children received HBcAb-positive allografts without preventive treatment in 11 cases (5/11,45.5 ％),57 (56.4％) of the children received HBcAb-negtive allografts,and 1.7％ (1/57) of the children had de novo hepatitis B infection.Conclusion Anti-HBc-positive donors can significantly increase the incidence of de novo HBV infection in HBsAg-negative recipients without preventive treatment.with the appropriate treatment strategy,HBcAb allografts can safely used in pediatric recipients.
