Therapeutic effect of Shenfu Injection on secondary aplastic anemia of tumor patients after chemotherapy

Objective: To explore the effect of Shenfu Injection, SFI) on the secondary aplastic anemia (AA) of tumor patients after chemotherapy (CT).Methods: The 15 cases of SFI treated group, 10 cases of control group, 25 cases of SFI + granulocyte-macrophage colony stimulating factor (GMCSF) treated group and the group of 23 GM-CSF-treated tumor cases of secondary AA after CT were compared, with their increasing rate and the rebound speed of neutrophil, platelet, bone marrow nucleated RBC, granulocyte, and megakaryocyte all being investigated.Results: The increasing rate and rebound speed of granulocyte, platelet, and the increasing rate of bone marrow nucleated RBC, granulocyte, megakaryocyte were obviously higher than those of the control, and the clinical manifestations were also obviously improved. The increasing rate of platelet, bone marrow nucleated RBC, megakaryocyte of the SFI + GM-CSF group were higher than those of the group which used GM-CSF alone, while the increasing rate of granulocyte in blood and bone marrow in both groups was similar.Conclusion: Significant efficacy was shown in SFI for the treatment of secondary AA of tumor patients after CT.

Real-time refinement of subthalamic nucleus targeting using Bayesian decision-making on the root mean square measure.

The subthalamic nucleus (STN) is a major target for treatment of advanced Parkinson's disease patients undergoing deep brain stimulation surgery. Microelectrode recording (MER) is used in many cases to identify the target nucleus. A real-time procedure for identifying the entry and exit points of the STN would improve the outcome of this targeting procedure. We used the normalized root mean square (NRMS) of a short (5 seconds) MER sampled signal and the estimated anatomical distance to target (EDT) as the basis for this procedure. Electrode tip location was defined intraoperatively by an expert neurophysiologist to be before, within, or after the STN. Data from 46 trajectories of 27 patients were used to calculate the Bayesian posterior probability of being in each of these locations, given RMS-EDT pair values. We tested our predictions on each trajectory using a bootstrapping technique, with the rest of the trajectories serving as a training set and found the error in predicting the STN entry to be (mean +/- SD) 0.18 +/- 0.84, and 0.50 +/- 0.59 mm for STN exit point, which yields a 0.30 +/- 0.28 mm deviation from the expert's target center. The simplicity and computational ease of RMS calculation, its spike sorting-independent nature and tolerance to electrode parameters of this Bayesian predictor, can lead directly to the development of a fully automated intraoperative physiological procedure for the refinement of imaging estimates of STN borders.     

Spontaneous regression of gastric varices after iatrogenic injury to a gastrorenal shunt

We present a patient with gastric varices complicating portal hypertension caused by liver cirrhosis related to hepatitis C virus. The patient underwent balloon‐occluded retrograde transvenous obliteration. The gastric varices almost completely disappeared, without any sclerotic agent being used, after iatrogenic injury of the gastrorenal shunt at the time of the interventional procedure.     

靶控输注咪唑安定对靶控输注丙泊酚镇静催眠效应的影响

目的评价靶控输注咪唑安定对靶控输注丙泊酚镇静催眠效应的影响。方法ASAI～Ⅱ级择期手术患者40例，随机分为四组：A组为单纯丙泊酚组，B、C、D组为丙泊酚 咪唑安定组，咪唑安定靶浓度分别为10、20、30ng／mL。咪唑安定达到平衡后，血浆靶控输注丙泊酚。记录丙泊酚效应部位浓度为1、2、3、4、5μg／mL时BIS值和OAA／S评分，并记录OAA／S评分达到4、3、2、1时丙泊酚效应部位浓度和BIS值，记录BIS值为50时丙泊酚效应部位浓度。结果1．咪唑安定达到平衡后，C组和D组BIS值显著下降；D组中OAA／S评分也显著下降，并低于B组和C组；2．随丙泊酚浓度升高四组患者．BIS值和OAA／S评分逐渐下降；3．相同丙泊酚浓度时，BIS值和OAA／S评分随咪唑安定浓度增加呈降低趋势；4．B、C、D三组患者OAA／S评分达到3、2、1以及BIS值达到50时所需丙泊酚效应部位浓度均显著低于A组，达到相同OAA／S评分D组所需丙泊酚效应部位浓度显著低于B组和C组。结论效应部位浓度为10、20、30ng／mL的咪唑安定均能显著降低丙泊酚靶控浓度，以达到需要的镇静深度；随咪唑安定浓度加深，降低作用越明显。
