Objective To investigate changes of brainstem auditory evoked potential (BAEP)and somatosensory evoked potential (SEP) in patients with acute cerebral infarction,and discuss their relation with prognosis of the patients.Methods The study involved 60 patients with acute cerebral infarction.Changes of BAEP and SEP in each patient were detected and recorded continuously.Prognosis evaluation was performed by using GCS.Another 60 age-matched and gender-matched healthy human beings were enrolled as controls.Results Incubation period of BAEP wave Ⅰ had no significant difference between the cerebral infarction and control groups (P ＞ 0.05).However,interspike intervals of other BAEP waves in cerebral infarction group were different from those in control group (P ＜ 0.05).A series of waves of SEP (P14-N60) were all significantly prolonged in cerebral infarction group (P ＜0.05).Conclusion BAEP and SEP can effectively reflect function of brain stem in patients with acute cerebral infarction and have some values in determining their prognosis.

BACKGROUND:There is little attention focused on the effect of isokinetic testing about the variation of angular velocity on pain and muscle strength in the evaluation of curative effect of McConnel taping. OBJECTIVE: To evaluate the changes of quadriceps muscle strength and perceived pain levels in patients with patelofemoral pain syndrome before and after corrective McConnel taping in isokinetic testing. METHODS:A total of 34 patients with patelofemoral pain syndrome were evaluated in isokinetic testing for concentric contraction muscular strength, including the maximum torque, the total work, and the average work in 60 (°)/s and 180 (°)/s angular velocity, before and after the interventions of McConnel taping. The visual analogue scale scores were recorded. RESULTS AND CONCLUSION: The visual analogue scale scores were slightly decreased in angular velocity of 60 (°)/s after obturation when compared to before obturation (P > 0.05), while the scores were significantly decreased in angular velocity of 180 (°)/s (P < 0.05). The maximum torque, the total work, and the average work were slightly increased after obturation, but showed no significant difference in angular velocity of 60 (°)/s (P > 0.05), while significantly increased in 180 (°)/s angular velocity (P < 0.05). McConnel taping significantly improves the curative effect in patients with patelofemoral pain syndrome under low load joint movement.

Objective To evaluate the effect of cytokine-induced killer cells (CIKs) as an adoptive immunotherapy option for treatment of leukemia relapse after allo-hematopoietic stem cell transplantation (allo-HSCT).Methods Two cases of infusion of donor CIKs in patients with leukemia relapse after allo-HSCT were retrospectively analyzed.Patient one relapsed 986 days (+986d) after HLA-matched unrelated donor allo-HSCT.Applications of chemotherapy only resulted in short term remission,but allo-CIKs were successfully expanded from the patient's peripheral blood mononuclear cells of donor origin.Totally five cycles of CIKs infusion were infused as an alternative of adoptive immunotherapy.Patient two had recurrent in the + 158d after HLA-matched sibling alloHSCT.At + 204d and + 294d,two cycles of CIKs which were expanded from donor peripheral blood mononuclear cells were infused.Results One cycle of CIKs was given to patient one after the application of chemotherapy to reduce the tumor burden,and the patient successively achieved complete remission.Again after additional four cycles of CIKs infusion,consistent remission was maintained during the following seven months.Patient two who had relapsed disease posttransplantation,achieved cytological complete remission after withdrawal of immunosuppressants and undergoing chemotherapy combined with G-CSF mobilized stem cell infusion.However,at + 187d,the patient suffered from side-effect of acute graft versus host disease and extramedullary infiltration.The symptoms were alleviated markedly after one cycle of CIKs infusion at + 204d.Moreover,the pain disappeared after an additional infusion at + 294d.And up to the present,the bone marrow aspiration showed complete remission while the extramedullary disease vanished.Conclusion The use of CIKs in the treatment of leukemia relapse after allogeneic bone marrow transplantation can be feasible and well tolerated.

BACKGROUND: BuCy2 composed of large-dose oral busulfanum and cyclophosphamide has been one of the main conditioning regimens before transplantation, but oral busulfanum can result in many side effects.OBJECTIVE: To evaluate the efficacy and safety of the conditioning regimen with intravenous busulfanum (Ⅳ Bu) in hematopoietic stem cell transplantation (HSCT) for malignant hematopathy.DESIGN: Case observation.SETTING: Department of Hematology, Union Hospital,Tongji Medical College, Huazhong University of Science and Technology.PARTICIPANTS: A total of 13 patients with chronic myelogenous leukemia (CML) and 6 patients with acute leukemia,who received allogeneic HSCT with the conditioning therapy of modified BuCy2, were enrolled at Institute of Hematopathy, Union Hospital, Huazhong University of Science and Technology from May to December 2006. There were 12 males and 7 females aged 14-50 years with an average of 33 years, and there were 9 cases of related transplantation and 10 cases of unrelated transplantation. Hematopoietic stem cells (HSCs) were harvested from peripheral blood of 18 subjects and bone marrow of 1 subject. All patients and their family members signed the informed consent.METHODS: All patients were treated with allogeneic HSCT with the conditioning therapy of intravenous BuCy2.All patients received the modified combination of busulfanum and cyclophosphamide that was commonly utilized currently.Hydroxycarbamide 40 mg/kg was orally taken ten days before transplantation. Arabinosylcytosin (Ara-C) 2 g/m2 was injected via vein nine days before transplantation. Busulfanum ampule 0.8 mg/kg (equal to 1 mg/kg oral administration)was given by central venous cannula eight, seven and six days before transplantation. The injection was performed over 2 hours controlled by infusion pump, once every 6 hours, totally 12 times. Busulfanum was diluted by saline or 5% glucose to about 0.5 g/L (about 10 times) before Ⅳ Bu. Cyclophosphamide 1.8 g/m2 was intravenously injected every day from five and four days before transplantation. Methyl-CCNU 250 mg/m2 was taken orally three days before transplantation. Occurrence of hepatic vano-occlusive disease (HVOD) and its side effects were determined. Follow-up was performed at month 6.5 after operation to observe disease recurrence and patient survival.MAIN OUTCOME MEASURES: Occurrence and side effects of HVOD 100 days after transplantation, and results of follow-up.RESULTS: Totally 19 patients were involved in the result analysis. In 13 days after transplantation, blood conversion,chromosome karyotype and DNA polymorphism tests verified that reconstruction of hematopoietic function was obtained and two patients got recurrence, of which one patient got complete remission after receiving fludarabine plus cytarabine plus granulocyte colony-stimulating factor (G-CSF) and HSCs from peripheral blood. DNA polymorhism test verified that re-engraftment was obtained. Another patient received chemotherapy. Other patients lived well.
