1Sirolimus inhibits growth of human hepatoma cells alone or combined with tacrolimus, while tacrolimus promotes cell growth显示文摘AIM: Standard immunosuppression after organ transplantation stimulates tumor growth. Sirolimus has a strong antiproliferative and a tumor inhibiting effect. The purpose is to assess the effect on tumor growth of the immunosuppressive compounds sirolimus and tacrolimus alone and in combination on cells of human hepatocellular carcinoma.METHODS: We used the human cell lines SK-Hep 1 and Hep 3B derived from hepatocellular carcinoma. Proliferation analyses after treatment with sirolimus, tacrolimus, or the combination of both were performed. FACS analyses were done to reveal cell cycle changes and apoptotic cell death. The expression of apoptosis-related proteins was estimated by Western blots.RESULTS: Sirolimus alone or combined with tacrolimus inhibited the growth of both cell lines after 5 d by up to 35% in SK-Hep 1 cells, and by up to 68% in Hep 3B cells at 25 ng/mL. Tacrolimus alone stimulated the growth by 12% after 5 ng/mL and by 25% after 25 ng/mL in Hep 3B cells. We found an increase of apoptotic Hep 3B cells from 6 to 16%, and a G1-arrest in SK-Hep 1 cells with an increase of cells from 61 to 82%, when sirolimus and tacrolimus were combined. Bcl-2 was down-regulated in Hep 3B, but not in SK-Hep 1 cells after combined treatment.CONCLUSION: Sirolimus appears to inhibit the growth of hepatocellular carcinoma cells alone and in combination with tacrolimus. Sirolimus seems to inhibit the growth stimulation of tacrolimus.Guido Schumacher Marijke Oidtmann Anne Rueggeberg Dietmar Jacob Sven Jonas Jan M.

3Matched-pair analysis of postoperative morbidity and mortality for pancreaticogastrostomy and pancreaticojejunostomy using mattress sutures in soft pancreatic tissue remnants显示文摘BACKGROUND:After pancreaticoduodenectomy,the incidence of postoperative pancreatic fistula remains high,especially in patients with 'soft' pancreatic tissue remnants.No 'gold standard' surgical technique for pancreaticoenteric anastomosis has been established.This study aimed to compare the postoperative morbidity and mortality of pancreaticogastrostomy and pancreaticojejunostomy for 'soft' pancreatic tissue remnants using modified mattress sutures.METHODS:Seventy-five patients who had undergone pancreaticogastrostomy and 75 who had undergone pancreaticojejunostomy after pancreaticoduodenectomy between 2002 and 2008 were retrospectively compared using matched-pair analysis.A modified mattress suture technique was used for the pancreaticoenteric anastomosis.Patients with an underlying 'hard' pancreatic tissue remnant,as in chronic pancreatitis,were excluded.Both groups were homogeneous for age,gender,and underlying disease.Postoperative morbidity,mortality,and preoperative and operative data were analyzed.RESULTS:There were no significant differences between the groups for the incidence of postoperative pancreatic fistula (10.7% in both).Postoperative morbidity and mortality,median operation time,median length of hospital stay,intraoperative blood loss,and the amount of intraoperatively transfused erythrocyte concentrates also did not significantly differ between the groups.Patient age >65 years (P=0.017),operation time >350minutes (P=0.001),and intraoperative transfusion of erythrocyte concentrates (P=0.038) were identified as risk factors for postoperative morbidity.CONCLUSIONS:Our results showed no significant differences between the groups in the pancreaticogastrostomy and pancreaticojejunostomy anastomosis techniques using mattress sutures for 'soft' pancreatic tissue remnants.In our experience,the mattress sutures are safe and simple to use,and pancreaticogastrostomy in particular is feasible and easy to learn,with good endoscopic accessibility to the anastomosis region.However,the location of the anastomosis and the surgical technique need to be individually evaluated to further reduce the incidence of postoperative pancreatic fistula.Fritz Klein Marcus Bahra Matthias Glanemann Wladimir Faber Peter Warnick Andreas Andreou Safak Gül Dietmar Jacob 2012Hepatobiliary & Pancreatic Diseases International2012,11,1:9
4病原学和血清学检验方法在大山区血吸虫病流行区的应用显示文摘目的了解血吸虫病病原学及血清学检测方法在大山区流行区应用的效果,为制定防治对策提供科学依据。方法采用随机抽样法在大山区血吸虫病未控制县抽取流行程度轻、中、重的1个自然村,每村抽取35户作为调查对象。采用孵化法及Kato-Katz法进行病原学检查,同时采用检测抗体的ELISA和DDIA法对受试者进行血清学检查。结果总感染率为8.26%(29/351),孵化法三送三检与Kato-Katz法三送十二检2种病原学检查方法差异无统计学意义(χ2=1.831,P>0.05),孵化法一送一检与Kato-Katz法一送四检差异也无统计学意义(χ2=0.313,P>0.05)。不同流行程度村的查病结果Kato-Katz法差异无统计学意义(χ2=2.188,P>0.05),孵化法差异有统计学意义(χ2=7.203,P<0.05),DDIA和ELISA法在不同流行程度村的查病结果间差异均有统计学意义(χ2=22.36、36.282,P均<0.01)。ELISA、DDIA2种血清学筛检方法的敏感性、特异性和约登指数分别为65.52%、59.35%、0.25和44.83%、69.79%、0.15。ELISA法优于DDIA法(χ2=19.253,P<0.01)。ELISA结果与粪检有关联,但一致性较差(χ2=5.772,P<0.05,Kappa=0.076762),DDIA结果与粪检无关联(χ2=2.019,P>0.05)。结论防治实际工作中采用收集一次粪便孵化或制作三张Kato-Katz片,分别有62.07%、72.41%的感染者漏检,必将严重低估病情现状。检测血吸虫抗体的ELISA和DDIA2种血清学筛查方法将漏检34.48%、55.17%感染者,成为血吸虫病病情反弹的原因之一。陈绍荣 陈凤 周晓农 李宏军 Peter Jacob Steinmann 杨忠 李远林 2007寄生虫病与感染性疾病2007,5,1:7

10A Relocation-based Initialization Scheme to Improve Track-forecasting of Tropical Cyclones显示文摘A relocation procedure to initialize tropical cyclones was developed to improve the representation of the initial conditions and the track forecast for Panasonic Weather Solutions Tropical Operational Forecasts. This scheme separates the vortex perturbation and environment field from the first guess, then relocates the initial vortex perturbations to the observed position by merging them with the environment field. The relationships of wind vector components with stream function and velocity potential are used for separating the vortex disturbance from first guess. For the separation of scalars, a low-pass Barnes filter is employed. The irregular-shaped relocation area corresponding to the specific initial conditions is determined by mapping the edge of the vortex radius in 36 directions.Then, the non-vortex perturbations in the relocation area are removed by a two-pass Barnes filter to retain the vortex perturbations, while the variable fields outside the perimeter of the modified vortex are kept identical to the original first guess. The potential impacts of this scheme on track forecasts were examined for three hurricane cases in the 2011–12 hurricane season. The experimental results demonstrate that the initialization scheme is able to effectively separate the vortex field from the environment field and maintain a relatively balanced and accurate relocated first guess. As the initial track error is reduced, the following track forecasts are considerably improved. The 72-h average track forecast error was reduced by 32.6% for the cold-start cases, and by 38.4% when using the full-cycling data assimilation because of the accumulated improvements from the initialization scheme.GAO Feng Peter P.
