Although hemopoietic stem cell transplant have been used in treating malignant diseases of hematological system using high-dose chemotherapy and radiotherapy before transplant or non-transplant is very important. When the dose of chemotherapy and radiotherapy exceeds the ability the tissues can bear, normal tissue can be badly damaged, which limits the therapeutic efficacy of chemotherapy and radiotherapy. Treatments of hematological malignancies are expected to achieve the best therapeutic efficacy and the least damage of normal cells and tissues. Amifostine is an inorganic thiophosphate eytoprotective agent,its chemname is S-2(3-aminopropyl) amino dihydrogen phosphate.h is a prodrug whose active constitutent is free thiol,it can clears free radicals produced from cytotoxic drugs and radiotherapy in tissues exposed to them. It is a broad-spectrum cytoprotective agent which can protect multifarious normal tissues against damage of chemotherapy and radiotherapy. Using amifostine in proconditioning of hemopoietic stem cell transplant can lessen hematological and renal toxicity, it can also lessen renal toxicity produced by chemotherapeutics as platinum,cyclophosphamide and vincristine. The main purpose of this review is to discuss the cytoprotection of amifostine in hematological malignancies.

Objective To study the genes of a carbapenem-resistant Klebsiella pneumoniae strain isolated from a patient. Methods The antibiotic sensitivity test of a multidrug-resistant Klebsiella pneumoniae strain was done according to K-B and MIC method. Metallo-β-lactamase was detected by Modified Hodge Test and EDTA-disk synergy test. Both nine genes encoding β-lactamases, including blaKPC, blaIMP , blaVIM , blaSME , blaCTX-M , blaSHV, blaDHA , blaACT, Class Ⅰ integrase and Class Ⅰ integron were detected by PCR. Positive products were sequenced. Results The Klebsiella pneumoniae was resistant to carbapenems, cephalosporins, cefoxitin, ampicillin and trimethoprim/sulfamethoxazole. Only susceptible to aztreonam, gentamicin, tobramycin, amikacin, ciprofloxacin and levofloxacin. The blaIMP-1 and Class Ⅰ integron were positive. The blaIMP gene was identified by PCR and DNA sequencing confirmed that the gene belong to IMP-1 type Metallo-β-lactamase gene. The strain also carried Class Ⅰ integron and IMP-1 was located in Class Ⅰ integron 5'. Conclusions It is the first detection of IMP-1 Metallo-β-lactamase in Klebsiella pneumoniae. The production of IMP-1 carbapenemase is the main mechanism of carbapenem-resistant in Klebsiella pneumoniae, and multidrug resistance is related to ClassⅠ integron.

Objective:To determine blood magnesium and urinary magnesium in children with asthma exacerbation and discuss the relationship between the magnesium level and children with asthma attack. Methods:The observation group include 90 children who were 0~6 years old with asthma exacerbation that admission to our hospital since May 2008 to May 2012. The control group was 100 children with the same age to the observation group to accept the health examination. Every child in two groups were taking venous blood of 2ml and 24h urine samples. Record the amount of urine at the same time. Using automatic biochemical analyzer to detect the serum magnesium concentration and urinary magnesium concentration. Results: The urinary magnesium concentration of observation group was obviously lower than control group (t=8.52, P<0.001);the serum magnesium concentration of two groups had no significant difference (t=2.21, P>0.05). Conclusion:Children with asthma in acute attack stage with magnesium deficiency. Urinary magnesium concentration determination is simple, and it is a effective method that can be used to judge whether there is magnesium deficiency. Serum magnesium concentration cannot be used as a reliable indicator of magnesium ion balance.
