BACKGROUND: To predict the functional outcome basing on hospitalization data as earlier as possible has important significance for evaluating the prognosis and discharged recovery. In recent years, researches on the balance function of stroke patients has drew more and more attentions, but less related reports about the relationship between balance and discharge functional outcome are available.OBJECTIVE: To predict the discharg functional outcomes of stoke patients basing on hospitalization data, as well as the relationship between it and scores for Fugl-Meyer balance(FMB) and Berg balance scale(BBS).DESIGN: Multiple factors and multi-variable study based on patient' s clinical presentation.SETTING: Rehabilitative department in a college hospital.PARTICIPANTS: Between August 2002 and May 2003, 40 patients with stoke for the first time were hospitalized in Rehabilitative and Neurological Department of Tongji Hospital, who accorded with the enrolling standards.METHODS: The available hospitalization data and discharge functional outcomes were subjected to single factor and multiple factor analysis, and collected data includes the history of disease, physical examination, scores for FMB and BBS when hospitalization, scores for daily life ability(ADL)and functional independence measure(FIM) . Functional outcome was presented by the discharge FIM.MAIN OUTCOME MEASURES: Simple correlative analysis of BBS, FMB and FIM, regressive analysis of discharge FIM influencing factors.RESULTS: Simple liner correlative analysis indicted that scores for BBS and FMB was strongly correlated with the scores for FIM at hospitalization and discharge( P ＜ 0. 001 or P ＜ 0.05), regressive analysis revealed that scores for FIM, ADL and BBS at hospitalization could be used for predicting the discharge functional outcomes of stroke patients.CONCLUSION: Predictors for discharge functional outcomes includes scores for FIM, ADL and BBS when hospitalization, which are closely correlated with BBS.

Aim To investigate the effect of aloe-emodin on lipopolysaccharide(LPS)-induced production of nitric oxide and expression of inducible nitric oxide synthase in RAW264.7 cells.Methods RAW264.7 macrophage line in mice was induced by LPS to set up the inflammatory model.Nitric oxide(NO)production was examined by Griess reaction;the expression of iNOS mRNA was detected by RT-PCR analysis;NO radical generation was tested by sodium nitroprusside method.Results Aloe-emodin at the dose of 0.69～2.5 mg·L~(-1) exhibited the inhibitory effect on LPS-induced NO production in a dose-dependent and time-dependent manner;aloe-emodin at the dose of 0.63～5.00 mg·L~(-1) suppressed LPS-induced iNOS mRNA expression in RAW 264.7 cells.However,aloe-emodin had no scavenging effect on sodium nitroprusside-triggered NO production,and didn't affect iNOS enzyme activity.Conclusion Aloe-emodin inhibited signifi-cantly LPS-induced NO production through suppressing inducible NO synthase(iNOS)expression at mRNA level in a dose-dependent and time-dependent manner,but failed to affect sodium nitroprusside-triggered NO production and iNOS enzyme activity.

Objective To study the effect of Cistanche deserticola Y C Ma (CDPS) on lymphocyte proliferation in mice. Methods The lymphocyte proliferation with or without mitogen was assessed by MTT assay in vitro. The immunosuppressed mice were induced by cyclophosphamide,and the spleen and thymus were weighted to determine the immune organ indexes in the normal or immunosuppressed mice. Thymocyte proliferation was employed to assess the activity of IL-2. Results CDPS significantly promoted both non-activated splenic lymphocytes and lymphocytes activated by ConA or LPS,and CDPS increased the secretion of IL-2 by splenic lymphocytes. CDPS (ip) remarkably increased indexes of spleen in normal or immunosuppressed mice,and also improved the indexes of immunosuppressed mice induced by cyclophosphamide. Conclusion CDPS can significantly promote the proliferation of splenic lymphocytes,and it may be related with promotion of secretion of IL-2 by splenocytes.

ObjectiveTo observe the efficiency of hematopoietic stem cell transplantation to the treatment of hematological malignancies and explore prevention and treatment of the complications correlated with HSCT. Methods110 patients with hematological malignancies which were treated by HSCT were recruited. 61 patients were treated with autologous peripheral blood hematopoietic stem cell transplantation (auto-PBSCT), 49 patients were treated with allogeneic hematopoietic stem cell transplantation (allo-HSCT).Among them,there were 28 patients were used by all HLA-identical sibling allo-PBSCT,20 patients were used by haploid allogeneic bone marrow and peripheral blood stem cell transplantation, one case of acute lymphoblastic leukemia in children were treated with cord blood stem cell transplantation.Results109(99.1％) patients acquired hemopoietic reconstruction. The median time of neutrophils≥0.5×109/L, and platelets≥20×109/L were 10 days and 12 days in auto-PBSCT,and were 12 days and 15 days in allo-PBSCT.The incidence of Ⅰ-Ⅲ degree of acute GVHD (aGVHD) in allogeneic transplantation was 28.6 ％(14/49),however,the incidence of chronic GVHD (cGVHD) was 32.6 ％(16/49).The median follow-up time was 36 (1～60) months.84 patients (76.4 ％) were disease-free.Among them,73.8 ％(45/61) were in auto-PBSCT group,(79.6 ％)39/49 were in allo-HSCT group.26 patients (23.6 ％) were died.There were 26.2 ％(16/61) who were in auto-PBSCT group died of disease relapse,3.3 ％(2/61) had disease relapse.There was no transplant-related deaths.18.4 ％(9/49) who were in allo-HSCT group died of disease relapse, 6.1％(3/49)had disease relapse, 2.0 ％(1/49)died of transplant-related deaths. ConclusionHematopoietic stem cell transplantation is a safe and effective way for the treatment of malignant hematopathy patients,also an important mean for treatment of blood diseases.

Objective To compare and explore the efficacy of regional citrate anticoagulation therapy and regional heparin anticoagulation therapy in continuous renal replacement therapy ( CRRT) of acute kidney injury ( AKI) patients with risk of bleeding by an retrospective study. Methods A total of 96 AKI patients with risk of bleeding were collected retrospectively and treated with CRRT. All the patients were divided into two groups:regional citrate group ( n=50) and regional heparin group ( n=46) . APTT, level of Ca2+, pH value, levels of HCO-3 and Na+, time of blood filter using and incidence of adverse events were compared between the two groups. Results Percentage of hypernatremia, metabolic alkalosis and elevation of transaminase in regional citrate group were 2.3%, 6.1%, 1.9%, respectively, those in the regional heparin group were 1.6%, 0.9%, 1.6%, respectively. The time of blood filter using in regional citrate group and regional heparin group were (70.0±5.3) h and (48.0±2.7) h, respectively (P<0.05). Incidence of bleeding event in regional citrate group and regional heparin group were 3.8% and 13.0%, respectively (P<0.05). Conclusion In patients with coagulation disorders or bleeding risk undergoing CRRT, regional citrate anticoagulation therapy is safer and more effective, and worthy of promotion.

OBJECTIVE To compare the anti-oxidative effects of "three decoctions for COVID-19" (Qingfei Paidu decoction, Huashi Baidu decoction, Xuanfei Baidu decoction) in parallel experimental models. METHODS In the cell-free system, the total antioxidant capacity was investigated by FRAP method. The scavenging effects of DPPH radicals and superoxide anions were evaluated by DPPH and NBT reduction method, respectively. The scavenging effect of hydroxyl radicals was determined by a fluorescence method based on the end-product MDA. The anti-lipid peroxidation activity was investigated using the FeSO4-induced rat liver homogenate MDA method. Based on these five antioxidant indicators, the antioxidant capabilities of the extracts of three decoctions were parallelly compared in the cell-free system. Furthermore, in lipopolysaccharide-activated RAW264.7 cells, the productions of intracellular and mitochondrial reactive oxygen species(ROS) were detected using the L-012 probe and the MitoSOX mitochondrial superoxide red fluorescence probe, respectively; and intracellular NADPH oxidase activity was measured using the lucigenin probe. These three indicators were used to parallelly compare the antioxidant capabilities of the extracts of three decoctions. RESULTS In the cell-free system, three decoctions for COVID-19 could concentration-dependently scavenge DPPH radicals, superoxide anions and hydroxyl radicals, and potently inhibit the lipid peroxidation. At the equal extract concentration, their scavenging effects on DPPH radicals and superoxide anions and the total antioxidant capacity were comparable; while Huashi Baidu decoction exhibited the strongest ability to scavenge hydroxyl radicals and inhibit lipid peroxidation. In the cell system, three decoctions could reduce lipopolysaccharide-elevated intracellular ROS level by weakening NADPH oxidase activity; meanwhile, they could decrease mitochondrial ROS productions, among which Qingfei Paidu decoction possessed the most comprehensive effection. CONCLUSION Collectively, three decoctions for COVID-19 exert diverse antioxidant effects in both cell-free and cell systems, and each of them possesses the distinct advantages. Given that oxidative stress is pivotal during the pathological process of COVID-19, the results may suggest that the antioxidant ability of three decoctions is one of the pharmacodynamic basis for their clinical use.
