Objective To explore the clinic values of early goal directed treatment (EGDT)with the target of mixed venous oxygen saturation (SvO2)and difference of mixed venous-arterial partial pressure of carbon dioxide (Pv-aCO2) in monitoring of oxygen metabolism and treatment for patients post open-heart operation. Methods A prospective study was conducted. The adult patients admitted to Third People's Hospital of Chengdu from December 2011 to March 2014 with SvO2<0.65 and blood lactic acid>2 mmol/L when admitted in intensive care unit(ICU)were selected on whom elective open-heart operation and pulmonary artery catheter examination were done. All patients received EGDT with the target of SvO2≥0.65 and Pv-aCO2<6 mmHg (1 mmHg=0.133 kPa)and were divided into three groups by the values of SvO2 and Pv-aCO2 at 6-hour after ICU admission:A group with SvO2≥0.65 and Pv-aCO2<6 mmHg,B group with SvO2≥0.65 and Pv-aCO2≥6 mmHg,and C group with SvO2<0.65. Then the changes and prognosis of the patients in different groups were observed. Results 103 cases were included,44 in A group,31 in B group and 28 in C group. The acute physiology and chronic health evaluationⅡ (APACHEⅡ)score in group A were significantly lower than that in group B or C at 6,24,48 and 72 hours (T6,T24,T48,T72)of ICU admission (T6:11.4±5.8 vs. 13.9±5.4,13.7±6.4;T24:8.8±3.7 vs. 10.8±4.8,11.8±5.4;T48:8.7±4.1 vs. 9.6 ±4.2,10.2 ±5.1;T72:7.5 ±3.4 vs. 8.6 ±2.9,9.2 ±4.2,all P<0.05),and the sequential organ failure assessment (SOFA)showed the same tendency (T6:6.5±4.3 vs. 8.0±3.8,9.1±4.5;T24:6.6±3.6 vs. 8.6±3.9, 8.5±3.3;T48:5.2±3.4 vs. 7.0±3.6,7.6±5.1;T72:4.6±2.4 vs. 5.8±2.5,6.8±3.5,all P<0.05). The values of blood lactic acid (mmol/L)in group A and B were significant lower than that in group C at T6,T24,T48 and T72 (T6:1.60 ±0.95,2.20 ±1.02 vs. 2.55 ±1.39;T24:2.26 ±1.26,2.70 ±1.36 vs. 3.34 ±2.36;T48:2.01 ±1.15, 2.17 ±1.51 vs. 2.42 ±1.63;T72:1.62 ±1.14,1.64 ±0.75 vs. 2.11 ±1.29,all P<0.05). The time of machine ventilation(days)in group A or B was significantly shorter than that in group C(2.8±2.0,3.6±2.3 vs. 5.0±3.1,both P<0.05). ICU day (days)in group A was significant shorter than that in group C (4.6±2.5 vs. 6.5±3.7,P<0.05). The 7-day mortalities after operation in three groups were significantly different. Compared with group A (2.3%),the odds ratio (OR)in group B (22.6%)was 12.5 (P<0.05),group C (25.0%)14.3 (P<0.05). The morbidity and 28-day mortality in three groups were not significantly different. Pv-aCO2 negatively correlated with cardiac index(CI, r=-0.685,P=0.000),but not correlated with blood lactic acid(r=0.187,P=0.080). Conclusions EGDT with the target of SvO2≥0.65 and Pv-aCO2<6 mmHg improved the general condition and tissue hypoxia,shortened the time of machine ventilation and duration of hospitalization in ICU,and decrease the 7-day mortality.

Objective To explore a quick and feasible method of screening malaria parasite by using a Sysmex XE-2100 hematology analyzer though alarm information on high eosinophil count and atypical eosinophil distributions in the WBC scattergram. Methods Sysmex XE-2100 hematology analyzer was used for complete blood cell analysis. Microscopic review was used when high eosinophil count and atypicaleosinophil distributions in the WBC scattergram were found. If the review showed normal eosinophil cells, wecontinued to focus on red cell for searching malaria parasite. Results Among 1 501 specimens showing higheosinophil counts and atypical eosinophil distributions, nine cases with normal eosinophil cells were indisaccordance with the hematology analyzer, six of them showed high eosinophil count in the Sysmex XE-2100 hematology analyzer, whose distribution was located close to neutrophil clusters in scattergram. The otherthree had an abnormal WBC scattergram. There was no gap between eosinophil clusters and neutrophilclusters, which brought no classified results. But all the nine specimens had been found the trophozoite,schizont and merozoite in blood smears. Conclusions There were great possibility of the existence of themalaria parasite in specimens when hematology analysis showed high eosinophil count and atypical eosinophildistributions in the WBC scattergram in a Sysmex XE-2100 hematology analyzer, although these alarm wasnot comfirmed by microscopic review. This method provides not only a simple and reliable way for quickscreening malaria parasite but also has a great value in preventing the undetected ratio on malaria parasite.

BACKGROUND: The principal deterrent to the success for hematopoietic stem cell transplantation (HSCT) is the complications after transplantation. The complications are associates with the conditioning regimens in the early stage. The highly-effective preparative regimens of proper dose and low-toxicity are the key to the successful HSCT.OBJECTIVE: To evaluate the curative effects and regimen related toxicity (RRT) of high-dose alkylating-agent-based chemotherapy as conditioning regimens for HSCT in the patients with hematological malignancies.DESIGN: Controlled study with observation.SETTING: Department of Hematology, Affiliated Hospital of Xuzhou Medical College.PARTICIPANTS: A total of 45 patients with leukemia and lymphoma hospitalized at Affiliated Hospital of Xuzhou Medical College from July 1997 to February 2006 were enrolled, including 31 males and 14 females. The median age was 31 years (from 7 to 52 years). The median course was 8 months (from 5 to 17 months) until transplantation.METHODS: Totally 45 patients with leukemia and lymphoma approached or got complete remission were treated by bone marrow transplantation and peripheral blood stem cell transplantation with preparative regimens of high-dose alkylating-agent-based chemotherapy. RRT was graded according to Bearman proposal, from grade 0 (no toxicity) to grade Ⅳ (fatal toxicity). The period of hematopoietic reconstitution, the rates of complete remission and relapse and disease-free survival were statistically observed in transplant recipients.MAIN OUTCOME MEASURES: Occurrence of RRT as conditioning regimens.RESULTS: ①Five patients did not show any toxicity. The greatest toxicity of grade Ⅲ was uncommon (13%, 6/45). Most of the cases with RRT were in grade Ⅰ - Ⅱ and severe oases in grade Ⅲ were rare. In grade Ⅰ - Ⅱ, stomatocace and gastrointestinal toxicity were common respectively of 73% (33/45) and 51% (23/45) which were recovered in short time after treatment; Heart toxicity was rare and only in grade Ⅰ, most of which were tachyoardia and changes of ST-T shape. The increase of transaminase was common in the clinical manifestations of liver RRT except two cases of HVOD.There were four oases of HC, in which one was delayed. RRT on kidney, lungs and CNS was uncommon. ②Totally 43 patients engrafted gained hematopoietic reconstitution, 2 patients died of implant failure (4%). Within the median follow-up period of 37 (8-102) months, 10 patients relapsed, 5 patients died of transplantation-related complications and 28 patients were alive in a disease-free situation (62.2%). The cause of death within 100 days after transplantation was ordinal as acute graft-versus-host disease (GVHD), cytomegalovirus (CMV) interstitial pneumonia, disseminated infections,multiple organ failure and early relapses.CONCLUSION: Alkylating-agent-based conditioning regimens may be well tolerated with low toxicities for HSCT in leukemia and lymphoma.

Objective To study the clinical curative effect of Tongqiao Huoxue decoction combined with edaravone and hyperbaric oxygen for treatment of delayed encephalopathy after carbon monoxide poisoning (DEACMP). Methods A prospective study was conducted. Forty-six patients with DEACMP admitted into Yidu Central Hospital of Weifang Medical College from January 2012 to January 2014 were randomly divided into observation group (23 cases) and control group (23 cases). The basic treatments of two groups were identical. Based on the basic treatments including hyperbaric oxygen and citicoline sodium injection etc, the observation group was treated with our-self made Tongqiao Huoxue decoction which could be modified in accord to the individual differentiation of syndromes in traditional Chinese medicine (the composition of decoction included Paeoniae Radix Rubra 15 g, Chuanxiong Rhizoma 15 g, Persicae Semen 15 g, Carthami Flos 15 g, Zingiberis Rhizoma Recens 3 pieces, Jujubae Fructus 2 pieces, Moschus 0.5 g, Allium Fistulosum 1 segment). The decoction was administered orally or by nasogastric gavage, one dosage everyday for 1 month, and in the mean time, edaravone intravenously drip 30 mg was given to the observation group twice a day for 14 days. The control group was given hyperbaric oxygen and other conventional treatment for 30 days. The clinical therapeutic effect and adverse reaction were observed after treatment for 30 days. The changes of intelligent level were detected by Hasegawa dementia scale (HDS), and the changes of latency of P300 were measured by electromyologram/evoked potential instrument in two groups before and after treatment. Results The total effective rate in observation group was significantly higher than that in control group [91.3% (21/23) vs. 65.2% (15/23), P < 0.01]. Elevation of creatinine occurred in 1 case, moderate increase in alanine aminotransferase (ALT) appeared in 1 case, and both of them were reduced to normal after treatment in observation group; no adverse reaction occurred in control group. The HDS scores were significantly higher 30 days after treatment than those before treatment in the two groups [control group:13.4±2.8 vs. 6.8±2.3, observation group:20.8±3.4 vs. 6.6±2.5, both P<0.05]. The latency of P300 after treatment was significantly lower in two groups than that before treatment [control group (ms): 355.7±25.7 vs. 385.5±27.8, observation group (ms): 337.3±24.6 vs. 386.8±25.4, both P < 0.05], the change in observation group being more significant [the HDS score: 20.8±3.4 vs. 13.4±2.8, the latency of P300 (ms): 337.3±24.6 vs. 355.7±25.7, both P<0.05]. Conclusion Tongqiao Huoxue decoction combined with edaravone and hyperbaric oxygen has favorable cognitive effect on patients with DEACMP, thus, it can be used extensively in clinic.

BACKGROUND: The primary qualification of peripheral blood stem cell transplantation (PBSCT) is the effective mobilization and harvesting of hematopoietic stem cells. The mobilization efficacy is closely related to the selection of high-efficacy low-toxicity regimen, the timing of mobilization and harvesting as well.OBJECTIVE: To investigate the efficacy of mitoxantone (MIT) combined with high-dose arabinosylcytosin (Ara-C),followed by granulocyte colony-stimulating factor (G-CSF) alone or combination of G-CSF and granulocyte-macrophage colony-stimulating factor (GM-CSF) on mobilizing PBSCs in patients with hematological malignancies and solid tumors.DESIGN: Controlled study with observation.SETTTNG: Department of Hematology, the Affiliated Hospital of Xuzhou Medical College.PARTICIPANTS: Forty-two patients with hematological malignancies and solid tumors admitted to Department of Hematology, Xuzhou Medical College from September 1998 to December 2006 were involved in this study. They were diagnosed according to FAB classification criteria and new WHO proposals. The involved patients, 25 male and 17 female, averaged 29 years ranging from 7 to 54 years and weighted (52±18) kg. Among them, 12 were patients with acute myeloblastic leukemia, 6 were patients with acute lymphoblastic leukemia (ALL), 1 was patient with chronic granulocytic leukemia (CGL) at chronic phase, 15 were patients with non-Hodgkin lymphoma (NHL), 4 were patients with Hodgkin lymphoma (HL), 2 was patient with multiple myeloma (MM), 2 were patients with advanced breast cancer. All the patients apprcached to or got complete remission after conventional chemotherapy. No tumor cell infiltration was observed in bone marrow cytological examination. The functions of the main organs such as heart, lung, liver and kidney,and so on, were normal. The patients underwent an average of 8-course chemotherapy before the mobilization. Informed consents of all the patients were obtained.METHODS: MIT was intravenously injected at 10 mg/(m2·d)for 2 to 3 days, then Ara-C was also intravenously injected at 2 g/m2 every 12 hours for 1 to 2 days. When white blood cell (WBC) count recovered from the lowest value, 5 to 7.5 μg/ (kg·d)G-CSF was applied in 20 patients for 3 to 5 days successively. And 5 to 7.5 μg/ (kg·d)G-CSF and 5 to 7 μ g/(kg·d)GM-CSF were applied in another 22 patients at 6:00 in the morning and in the evening, respectively. PBSCs harvesting started when WBC > 2.5×109 L-1, especially when CD34+ cells≥ 1%,WBC was doubly increased. Autologous peripheral blood mononuclear cells (MNCs) were collected with CS3000 plus blood cell separator for detecting the level of CD34+ cells and T lymphocyte subsets. CFU-GM assays were performed in a methyl-cellulose-based clonogenic assay.① MNCs mixed with FITC-labeled CD34+, CD3 and CD8 monoclonal antibodies as well as CD4 PE-labeled CD monoclonal antibody at 4 ℃ for 30 minutes. 5×105 cells were determined, and CD3 and CD34+ levels, CD4/CD8 were determined by flow cytometer.Colony forming unit-granulocyte macrophage (CFU-GM) was determined with methyl cellulose. ② Related adverse reactions were observed after operation. ③ Aiming to different types of diseases,autologous PBSCs were back infused 36 to 48 hours after pre-disposal treatment. MNCs count and trypan-blue drying were done. Levels of CFU-GM and CD34+ cells were determined after unfreezing.MATN OUTCOME MEASURES: ① Changes in CD34+ cells and T lymphocyte subsets before and after mobilization. ② Postoperative related adverse reactions. ③ Back perfusion volume of autologous PBSCs (MNCs count, the number of CFU-GM and CD34+ cells).RESULTS: Forty-two involved patients participated in the final analysis. ① Changes in CD34+ cells and T lymphocyte subsets before and after mobilization: Without using hematopoietic growth factors (HGF), the percentage of CD34+ cells in peripheral blood of the patients was (0.054±0.032)%. After using G-CSF/GM-CSF treatment, it was (1.82±0.76)%,which was obviously increased compared with that of without using HGF (P < 0.001). The CD34+ cells and CFU-GM yields of 22 patients in C-CSF plus GM-CSF combination group [(8.76±3.39)×106/kg, (3.52±1.33)×105/kg, respectively]were significantly higher than those of 20 patients in G-CSF alone group [(6.12±2.11)×106/kg, (2.03±1.07)×105/kg,respectively (P < 0.05)]. There were no obvious changes of T lymphocyte subsets in the patients when using G-CSF/GM-CSF for some days except that CD34+ cells increased gradually (P > 0.05). ② Postoperative related adverse reactions: Ⅱ to Ⅲ degree hair-loss was seen in all the patients. Blood platelets dropped to (54.43±26.14)×109 L-1 at different degrees. Infective fevers (37.8 ℃ to 41.0 ℃) occurred in 21 patients. But they were controlled in short term after antibiotics treatment. All the side effects of G-CSF and GM-CSF were mild and reversible, easily controlled with paracetamol or steroids. Bone pain (mainly in lumbosacral region) occurred in 13 patients when WBC went up quickly. ③ Back perfusion volume of autologous PBSCs: PBSCs were cryopreserved at -80 ℃ without program control for 2.0 to 6.5 months. The cell recovery rate was (88.7±7.4) %. Trypan blue exclusion rate was (92.1±5.5) %. The back perfusion volume of MNCs, CD34+ cells and CFU-GM yields were (5.21±2.44)×108/kg, (6.89±3.55)×106/kg, (2.58±2.33)×105/kg,respectively. ④Circulation blood volume were 10 to 16 L (end-point separation blood volume were all above trebling TBV). Hematopoiesis was well reconstituted in 40 patients received autologous PBSCT.CONCLUSTON: MIT and high-dose Ara-C chemotherapy combined with both G-CSF alone and G-CSF plus GM-CSF can safely and effectively mobilize autologous PBSCs, while G-CSF plus GM-CSF is superior to G-CSF alone.Large-volume leukapheresis is an important method to enhance the productive rate of stem cells and decrease the times of harvesting.
