This paper investigate the methods to detect engraftment rate of the four patients with hematological disorders who accepted nonmyeloablative allogeneic peripheral blood stem cell transplantation(NAPBSCT). To find out the best method, their engraftment rates were detected serially at different time after NAPBSCT by means of either FISH, or conventional chromosome analysis combined with R-banding analysis concurrently.The results were carefully compared with one another. All these four sex-mismatched cases were engrafted partially,and two of them changed to full engrafment. The results show no statistically significant difference in 3 groups (conventional method, FISH for hypermetaphase, FISH for interphase nuclei). But the results strongly indicate that FISH is a rapid, precise, objective,and reliable menthod for detection of the engraftment rate,and it is suitable for sex-mismatched NAPBSCT.

Objective To compare the applicability between ARF special severity scoring systems and intensive care unit (ICU) general severity scoring systems on predicting the hospital mortality of critical acute renal failure (ARF) patients. Methods The data of 29 patients with critical ARF were retrospectively analyzed. Two ARF special severity scoring models, acute tubular necrosis individual severity index (ATN-ISI) and Stuivenberg hospital acute renal failure scores (SHARF), and 3 ICU general severity scoring models, Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ), APACHE Ⅲ, Mortality Prediction Model Ⅱ (MPM Ⅱ), were used in the analysis. The receiver operating characteristic (ROC) curves were drawn up to assess the ability of these models in hospital mortality discrimination. Results All severity scores of the patients in survivor group (n=9) were lower than those of the patients in non-survivor group (n=20). There were statistical differentiations in the scores of ATN-ISI, APACHE Ⅱ, MPM Ⅱ-24h, MPM Ⅱ-72h between the survivor group and the non-survivor group (P

Objective To investigate the significance of HLA haploidentical peripheral blood stem cell transplantation for the treatment of intestinal form of acute radiation sickness. Methods Patient “A” from Shandong province suffered from a 60 Co radiation accident with a dose of 20-25Gy, and was diagnosed as intestinal form of acute radiation sickness. On the 3rd day after irradiation, total environmental protection (TEP), antibiotics treatment and emergency HLA zygosity with his elder sister were done, and HLA haploidentical peripheral blood stem cell transplantation was performed with a preconditioning regimen of “CTX+ATG+Flu”. The regimen for protecting from GVHD was “CsA/FK506+MMF+CD25+MSC”. Results WBC began to increase on the 17th day after treatment, and WBC recovered to 5.1?109/L on the 19th day, platelet to over 30?109/L, and RCT to normal. Bone marrow image showed hematopoietic recovery of the three cell lineages. Continuously detection of the implantation ratio of donor's cells by STR-PCR, sexual chromosome analysis and HLA zygosity showed stable complete donor-derived chimera. No GVHD was observed. On the 19th days after treatment, chest X-ray films and CT suggested that a mixed bacterial and fungous infection existed in the patient's lungs. The severest skin damage occurred on the 25th day which occupied 14% of whole body surface. The functions of lung, kidney and heart were damaged sequentially. The patient died of multiple organ failure (MOF) 33 days after admission. Conclusion It is the first time to report a successful HLA haploidentical peripheral blood stem cell transplantation for the treatment of intestinal form of acute radiation sickness in China. A successful transplantation might be a key for prolonging the survival period of such a patient.

Objective To report the diagnosis and treatment of an extremely severe bone marrow form of acute radiation sickness complicated with disseminated Trichosporon Asahii in Jining,Shandong province, China.Methods An extremely severe bone marrow form of acute radiation sickness was transfered to our hospital 3 days after the accident on October 24,2004.The patient was performed allogeneic stem cell transplantion from his brother and soon acquired hematogenesis recovery, however, refractory disseminated Trichosporonosis(mainly lung) then occured in the patient.after the hemato-reconstitusion,and gradually aggravate.Result Strong support treatment and high dosage combination of drug therapy were used to combat fungi ,the accumulative dose of Ampghotec (amphotericin B) was 2965mg, the accumulative dose of itraconazole was 4000mg, and the accumulative dose of Caspofungin(concidas) was 3020mg. The refractory disseminated Trichosporon Asahii was once partially controlled, but the radiation injury and infection were still becoming worse even after many kinds of antiinfection drugs, the patient then died of multiple organ failure on d75 after the accident. Conclution The combination of Ampghotec with Caspofungin and Itraconazole in the treatment of disseminated Trichosporon Asahii was effective, no related toxicity occured, which has not been reported before. However, with continuously injury of radiation, we couldn’t cure the Trichosporonosis thoroughly, and the patient finally died of multiple organs failure related with radiation and infection.According to the clinical treatment of the patient, we also acquired the experience that when we resolve the hematogenesis, to promote the immunologic reconstitution and the tissue damage repair, control the whole body radiation damage and infection will be the key point for this kind of patient to survive.

Objective To observe the changes of serum high-sensitivity C-reactive protein (hs-CRP) in 2 patients diagnosed as acute radiation sickness, and to evaluate its clinical significance. Methods Two victims from Shandong province, China were accidentally received a 60 Co irradiation from a dropped 60 Co source in 2004. They were exposed to more than 20Gy (patient A) and 9Gy (patient B) of X-ray irradiation respectively. The patient A was diagnosed as extremely severe bone marrow form of acute radiation sickness (ARS), and patient B was diagnosed as having developed intestinal form of ARS. The two patients successfully got HLA-haploidentical (patient A) and HLA-identical (patient B) peripheral blood stem cell transplantation, and their hematopoiesis recovered, but they cached serious bacterial infection in whole clinical course. Hs-CRP was quantitatively detected by automatically immunoturbidimetric assay. Result The serum level of hs-CRP in the two patients elevated quickly when they suffered from serious bacterial infection, and declined markedly when the infection was controlled effectively. The serum level of hs-CRP also increased slightly when the patients suffered from severe damage on organs or skin function. There existed 3 peak values of hs-CRP level in patient A when kept in the hospital, with a highest value of 188.8mg/L; there existed 4 peak values of hs-CRP level in patient B when kept in the hospital, with the highest value of 377.2mg/L. Conclusion The present results suggested that hs-CRP may be a good indicator to acute radiation sickness complicated with serious bacterial infection, for the hs-CRP levels may fluctuate following the bacterial infection and effectively controlling.

Objective To summarize the experimence of nonmyeloablative allogeneic peripheral blood cell transplantation in the treatment of chronic leukemia. Methods Seven patients, including 6 cases of chronic myeloid leukemia (in chronic phase), one of chronic lymphoid leukemia (in third stage), with HLA-identical siblings donor received allogeneic peripheral blood stem cell transplantation after a nonmyeloablative conditioning. Results All of them were engrafted with donor cells (4 with full of donor cells grafted, 3 with mixed chimerism) and recovered hematopoiesis (WBC recovered to more than 0.5 ?10 9/L during postoperative 9 day to 21 day and platelet recovered to more than 30?10 9/L during postoperative 11 day to 28 day). One of them developed a GVHD of degree IV. One of them developed aGVHD of degree I. Conclusion This procedure is much safe, effective and of less complications than the myeloablative condioning regimens and may represent another new approach in the management of patients with chronic leukemia.

Objective To observe the changes of the content of ATP,lactate and the activity of phosphofructokinase(PFK) in perihemotoma region in rabbit brain after intracerebral hemorrhage. Methods(The rabbits) were divided into 3 groups: normal group(N),hemorrhage group (H) and the sham group(S). The H and S groups were subdivided into 1 h, 6 h, 12 h, 24 h, 48 h and 72 h groups. A model of cerebral hemorrhage in rabbit with autologous blood infusion was set. The contents of ATP, lactate and water in perihemotoma region were measured and the metabolite concentration in edematous brain regions were corrected for dilution. The activity of phosphofructokinase was also determined.Results There was obvious edema in perihemotoma region at 1 hour postinfusion and getting more serious at 72 hours. ATP was moderately decreased at 1 hour, and remained in a similar level until 12 hours. There appeared another evident decrease in 24 hours [(13.29?2.92) ?g/g, about 58% of N group], and no obvious changes from 24 to 72 hours. The content of lactate increased in 1 hour and reached the peak at 12 hours [(21.01?0.18) ?mol/g]. Until 72 hours , the level of lactate [(12.89?0.25) ?mol/g] in hemorrhage group reach higher than in the normal and sham group. The activity of phosphofructokinase was decreased at 1 hour [(3.98?0.02) U/mg] and remained in a decreasing tendency to 72 hours. Conclusion The failure of energy metabolism occurs in 24 hours postinfusion,coming late somewhat to the brain edema. The result might be related to the changes of some enzymes, maybe a key role in energy metabolism.
