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.

Translational medicine has become the current focus in the field of medicine and health.To promote the development of translational medicine,the government should play multiple roles as planner,investor,coordinator,and supervisor,and to take its due responsibilities.

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 evaluate the preventive effect of combination of low-dose HBIg and Nucleoside analogues on recurrence of hepatitis B after liver transplantation. Methods Retrospectively analyzed HBV status and recurrence in patients accepting Nucleoside analogues plus low-dose HBIg as prophylaxis treatment after liver transplantation for HBV-related end-stage liver disease from December 1998 to Octomber 2009 in our center. Results In all the 1506 patients whose survival time >30 d after liver transplantation, 37 patients showed HBV recurrence, the HBV cumulative-recurrence rate of 1, 2, 3, 4, 5 and 6y was 1.3%,2. 4%,2. 7%,2. 9%,3. 7% and 4.6% respectively. The time of recurrence varied from 0. 3 to 66. 6 months (median 12. 8 months) after transplantation. Virus mutation could be tested in 9 cases of the 37 recurrence patients, including 4 YMDD cases, 2 YMDD + YIDD cases, 1 YMDD+YVDD cases, 1 YVDD case,and 1 YIDD case. Conclusions Liver transplantation is the principal therapeutic method for the patient with end-stage liver diseases related to HBV, with the effectively prophylaxis treatment to aim directly at HBV recurrence. If the patients who got HBV recurrence received targeted treatments, the situation can be controlled satisfactorily.

Objective To investigate the prognosis of liver retransplantation in patients with transplanted liver function failure caused by viral hepatitis recurrence.Methods From January 20th 2003 to November 20th 2012,the clinical data of 215 patients with liver retransplantation were retrospectively analyzed.The survival of transplanted liver of 18 cases with liver retransplantation because of hepatitis recurrence (eight cases of hepatitis C and 10 cases of hepatitis B) was compared with that of 115 cases with liver retransplantation for biliary complications.The dysfunction of transplanted liver after first transplantation and the survival after second liver retransplantation of patients with hepatitis C recurrence were compared with those of patients with hepatitis B recurrence.The prognosis analysis was compared by survival curves made by Kaplan-Meier method.Results Biliary complications were the most common reason in 215 patients with second liver retransplantation and which accounted for 115 cases (53.5 ％).Eighteen cases were hepatitis recurrence (8.4 ％).There was no significant difference in survival rate of the second transplanted liver between patients with hepatitis recurrence and biliary complication (P =0.543).The dysfunction of transplanted liver occurred at early stage (in three months) after first liver transplantation in part of patients with hepatitis C recurrence.The dysfunction of transplanted liver almost all occurred two years after first liver transplantation in patients with hepatitis B recurrence.Among eight patients with hepatitis C recurrence,the second transplanted liver of five cases survived more than one year.All the second transplanted liver of 10 patients with hepatitis B recurrence survived more than one year.There was no significant difference between them (P =0.060).Conclusions The prognosis of liver retransplantation in patients with hepatitis recurrence is similar with that of patients with biliary complications.The prognosis of liver retransplantation in patients with hepatitis B recurrence is good.

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 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.
