持续性植物状态患者脑脊液中氨基酸类神经递质的检测

OBJECTIVE: To detect the amino acid neurotransmitters in cerebrospinal fluid of patients in persistent vegetative state (PVS) to define their relation to the clinical manifestations of the patients. METHODS: The cerebrospinal fluid from 46 patients in PVS and 20 control patients were collected for detection of glutamic acid, aspartic acid, alanine and glycine by high-performance liquid chromatography. RESULTS: All the four amino acids were separated by chromatography within 25 min. The contents of all the 4 neurotransmitters in PVS group were higher than those in the control group, and their contents were inversely correlated to PVS score of the patients. The differences in the concentration of glycine and alanine were significant between PVS patients and the control patients (P<0.05). CONCLUSION: The patient's clinical manifestations are related to the contents of amino acid neurotransmitters in the cerebrospinal fluid of PVS patients.     

被覆自体微粒皮的辐照氟银猪皮移植治疗深度烧伤15例报告

OBJECTIVE: To study the feasibility of using irradiated porcine skin impregnated with fluorine and silver covered by autogenous skin granule graft in the treatment of severe burn injury. METHODS: Autogenous split-thick skin grafts were cut into small pieces (<1 mm3), which were transferred onto the sheet of porcine skin mounted with a layer of Xinnaxing ointment (2 mm in thickness). After eschar removal, the burn wound was covered with the prepared porcine skin, sutured and fixed with small holes at the lower site for drainage. The growth of autogenous granule skin was then observed and the criteria for therapeutic effect evaluation drafted. RESULTS: The layer of Xinnaxing ointment on the the porcine skin improved the adhesion of the autogenous small skin grafts, therefore full use could be made of the donor skin source. In the 15 patients receiving this treatment, the graft-covered area was (12.3+/-3.5) % that of the wound, with the donor-recipient area ratio of 1: (11.0+/-2.7) and subsequent healing time of 27.5+/-5.5 d. Primary healing was achieved in 9 cases, and secondary healing in 6, demonstrating similar clinical effect to that of allo-skin grafting. CONCLUSION: The method is easy and economic, which saves autogenous skin source and produces satisfactory clinical effect.     

脾切除贲门周围血管离断术后肝脏血流动力学和储备功能的变化

Objective To observe changes of hepatic hemodynamics and hepatic functional reserve after splenectomy and periesophagogastric devascularization. Methods From July 2006 to August 2007, thirty patients with portal hypertension caused by hepatitis B cirrhosis underwent splenectomy and periesophagogastric devascuiarization. The PVPG (portal venous pressure gradient) was measured by inductor continually during operation. The HAF (hepatic artery flow), PVF (portal venours flow) and hepatic arterial RI(resistant index) were measured with Doppler sonography. The EHBF(effective hepatic blood flow) and ICGR15 (indocyaninegreen retention rate at 15 minutes) were obtained respectively by indocyaninegreen clearance test before and after the operation. Results PVPG after laparotomy (19±4) mm Hg, ligating the splenic artery(14±4) mm Hg, splenectomy(14±3)mm Hg and periesophagogastric devascularization (12±4) mm Hg showed a tendency to decrease progressively. The PVF decreased [from (42±14) ml/s to (16±8) ml/s] and HAF increased in compensation after operation. The EHBF increased [from (0.48±0.10) L/min to (0.56±0.10) L/min], and the ICGR15 decreased (from 23%±8% to 18%±4%) postoperatively. Conclusion After splenectomy and periesophagogastric devascularization, the hepatic functional reserve improves at least in a short term notwithstanding the decrease of PVPG and PVF.

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.
