Chinese Journal of Medical Imaging 2015;(6):453-457
Purpose To assess the initial and follow-up CT findings of proven pulmonary invasive fungal disease (IFD) in patients after hematopoietic stem cell transplantation (HSCT), and to look for the signs for the prognosis. Materials and Methods A retrospective investigation of the CT features and the evolution process was carried out in 13 patients with proven pulmonary IFD diagnosed by histological examination. Results The first abnormal CT finding showed single nodule or mass in 5 cases, two nodules or masses in 2 cases, multiple nodules or masses in 2 cases, patchy consolidation in 1 case, patchy ground glass opacity (GGO) in 1 case, multiple stripes and GGOs in 1 case, and multiple consolidations in peribronchial distribution in 1 case; the presence of reversed halo sign (RHS) was found in 7 cases, not including 4 cases with aspergillosis. The median initial diameter was 32.0 mm, and the median maximum diameter was 51.5 mm. 9 of them reached partial remission after drug treatment, and 9 accepted operation resection. In the end, there were 5 cases cured, 1 keeping stable, 2 suspected recurrent on imaging, and 5 dead. In summary, it showed less than 2 nodules or masses in 7 patients (group 1) and other imaging patterns in 6 patients (group 2), the former group had smaller max diameter (t=4.397, P<0.01), the effective rate within 12 weeks, operation resection rate and final cure rate of group 1 were 85.7%, 100.0% and 71.4%, and those of group 2 were 16.7%, 33.3% and 0, respectively, with group 1 all higher than group 2 (P<0.05). Conclusion Nodule or mass is the most common CT finding of pulmonary IFD in HSCT recipients, with high incidence of reversed halo sign, less than 2 nodules or masses on the first CT imaging may be associated with better prognosis.

Objective To investigate the feature and the safety of birth process of induced labor by Propess.Methods The 380 cases of vaginal delivery women in our hospital between Sep.2006 to Dec.2007 who, were primigravida,term delivery,singleton gestation,vertex presentations and no standing contraindication, was considered as study group. The other 380 cases of women of labor spontaneous or intravenous oxyvenous in the same condition was considered as control group.The birth process,the amount of bleeding,the number of urine retention,and the prognosis of neonate were compared between the two group.Results The active phase and the second stage was abbreviated in the study group,(P0.05).Conclusion Propess was more effective and safe in shortening the active phase, the secona stage and reducing complications.

Objective To identify the changes of anti-HBs titers of patients with hepatitis B virus (HBV)-related diseases in the early stage (within the first week) post-liver transplantation (LT) and analyze their influencing factors.Method A total of 26 patients were enrolled in this study.They were all positive for HBsAg pre-LT and received the prophylaxis of lamivudine in combination with intravenous hepatitis B immunoglobulin (HBIG) in the first week post-LT.The titers of anti-HBs were detected daily in blood and drainage fluid every day in the first week post-LT.If the anti-HBs titers were greater than 1000 IU/L,blood and drainage were diluted,then detected again.Result The titers of anti-HBs in HBV-DNA negative groups,low HBsAg groups,and HBeAg negative groups were higher than those in the HBV-DNA positive groups,high HBsAg groups and HBeAg positive groups in the first five days post-LT.The median titer of anti-HBs in drainage fluid was 181.60 IU/L (0.00-968.50 IU/L).And the titer of anti-HBs in drainage fluid was correlated with anti-HBs titers in blood at the same time (r =0.927,P =0.000).The amount of anit-HBs calculated in drainage fluid was very high,but it fluctuated in a wide range (0.00-908.55 IU).Conclusion In the early stage post-LT,patients in high risk groups should receive higher doses of HBIG to maintain safe levels of anti-HBs,while the lower doses of HBIG are enough to the patients in low risk groups.Furthermore,the anti-HBs titers in blood aren't affected by the anti-HBs loss in drainage fluid.

Objective To evaluate the effect of isoflurane or sevoflurane inhalation before and after gestation on the N-methyl-D-aspartate (NMDA) receptor expression in offspring rat hippocampus.Methods Thirty female adult Sprague-Dawley rats,aged 3 months,weighing 250-300 g,were randomly assigned into 5 groups (n =6 each):control group (group C),exposure to isoflurane before gestation group (group BI),exposure to isoflurane during gestation period group (group PI),exposure to sevoflurane before gestation group (group BS),exposure to sevoflurane during gestation period group (group PS).The rats inhaled 1.6% isoflurane for 6 h at 1 day before gestation in group BI.The rats inhaled 1.6% isoflurane for 6 h at 6,10,14 and 18 day gestation in group PI.The rats were exposed to 2.4% sevoflurane for 6 h before gestation in group BS.The rats were exposed to 2.4% sevoflurane for 6 h at 6,10,14 and 18 day gestation in group PS.Twelve offspring rats from pregnant rats in each group were chosen on the day of birth (T1),and 7th,14th and 28th days after birth (T2-4) and sacrificed,and the hippocampi were then isolated for determination of the expression NMDA receptor (NR1,NR2A and NR2B).Results Compared with group C,no significant change was found in NMDA receptor expression in off spring rat hippocampus in groups BI and BS (P > 0.05),and the expression of NR1 and NR2A protein and mRNA was significantly up-regulated,and the expression of NR2B protein and mRNA was down-regulated at T1-3 (P <0.05),and no significant change was found in NMDA receptor expression at T4 in groups PI and PS (P > 0.05).Compared with group PI,the expression of NRI and NR2A protein and mRNA was significantly up-regulated,and the expression of NR2B protein and mRNA was down-regulated at T1 3 (P < 0.05 or 0.01),and no significant change was found in N MDA receptor expression at T4 in group PS (P > 0.05).Conclusion Isoflurane or sevoflurane inhalation before gestation does not affect the NMDA receptor expression in offspring rat hippocampus,while isoflurane or sevoflurane inhalation after gestation can induce abnormal expression of the NMDA receptor in offspring rat hippocampus,which may result in apoptosis in hippocampal cells and abnormality in the development of nervous system and cognitive function.

Objective To investigate effects of xeroderma pigmentosum B(XPB) gene on IL-6 induced proliferation and apoptosis in human vascular smooth muscle cells (VSMC).Methods Recombinant plasmid pcDNA3.1-XPB and vacant vector plasmid pcDNA3.1 were transfected stably into VSMC by liposome,and these cells were incubated with IL-6 at a 100 U/ml for 48 hours.The experiments were divided into six groups:blank control group; pcDNA3.1 group; pcDNA3.1-XPB group;IL-6 group; IL-6 + pcDNA3.1 group; IL-6 + pcDNA3.1-XPB group.The expression levels of XPB,Bcl-2,Bax and wild type p53 (wt-p53) were detected through reverse transcription polymerase chain reaction (RT-PCR) and Western blotting.The cell survival,cell cycle and apoptosis were examined with 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and flow cytometry,respectively.Results The transfection of pcDNA3.1-XPB increased the expression of XPB,Bax and wt-p53 (P<0.05 or P<0.01),decreased the expression of Bcl-2 (P<0.05 or P<0.01),and reduced the IL-6 induced effects on decreasing the expression of Bax and wt-p53 and increasing the expression of Bcl-2(P<0.05 or P<0.01).The over expression of XPB inhibited the cell growth(q=2.95,P< 0.05),and reduced the positive effects of IL-6 on VSMC growth ( 102.6 +6.2) % vs.(124.5 + 7.9) %,q=3.49,P<0.05.The over expression of XPB increased the apoptosis rate of VSMC(P<0.01 ) and the cell amounts of G0/G1 phase (q=2.99,P< 0.05),decreased the cell amounts of S phase(q=3.05,P<0.05),and reduced the IL-6 induced effects on decreasing the apoptosis rate of VSMC(5.9±2.1)% vs.(0.3±0.1)%,q=7.53,P<0.01; the cell amounts of G0/G1 phase(70.9±6.7) % vs.(54.8±2.9) %,q=6.91,P<0.01 ;and on increasing the cell amounts of Sphase(20.2+3.6)% vs.(36.4+7.2)%,q=8.54,P<0.01.Conclusions XPB gene could inhibit VSMC proliferation,promote VSMC apoptosis,and reduce the effects that IL-6 promotes VSMC proliferation and inhibits VSMC apoptosis.Therefore,XPB gene is likely to be potential molecular target for treatment of atherosclerosis.
