The effect of inducers on leukemia cell line K562 was studied in liquid culture system in vitro. Our experimental results showed that hemin induced cells only to produce hemoglobin without suppressing the growth of cells; Butyric sodium inhibited only the growth of cells without induction of hemoglobin; Cytosine arabinoside and harring-tonine could induce the hemoglobin of cells in their toxicant quantification.The results suggest that hemin and butyric sodium may have not be a therapeutic effect on leukemia patient; The effect of induced differentiation and cell toxicity of cytosine arabin- oside and harringtonine may be closely interconnected. Clinically, there is still the possibility of cell toxicity in treatment of leukemia patients with small dosage of those drugs, and the effect of those drugs may be the combination of cell toxicity, induced differentiation and cell sensitivity.

Penicillin Acylase from B. megaterium was immobilized on the porous bead carriers based on methacrylate, N,N-methelene-bis-methacrymide, glycidyl methacrylate, Allyl ether copolymers (Eupergit-c) either directly or after chemical modification with 1.6-deaminohexane and L-Lysine. Directly binding with oxirane groups, the most efficient immobilization results were achieved. The immobilization yield was markedly influenced by the ratio of amount of free enzyme to the weight of the carrier. The specific activities of 89 up to 475IU/g (wet) and binding protein of 6.9 to 112 mg/g (dry) were obtained when the free enzyme added to the immobilization solution was from 323IU/g (dry) up to 6250IU/g (dry). The residual activity of immobilized PGA in a recycling system at the 20th was about 92.5% of the initial value.

Objective To evaluate the risk factors for surgical site infection(SSI)following limb fracture surgery, and provide basis for making prevention and control measures.Methods Clinical data of 1 453 patients undergoing limb fracture surgery in 16 hospitals between January 1,2014 and June 30,2014 were collected,risk factors for SSI were analyzed by univariate and multivariate logistic regression analysis.Results Among 1 453 patients undergoing limb fracture surgery,12 developed SSI(0.83%).Univariate analysis showed that risk factors for SSI following limb fracture surgery were infection at the other sites 7 days before operation,time from injury to operation,opera-tion opportunity, duration of operation,open fracture, wound type, and anesthesia type ( all P < 0.05 ). Multivariate logistic regression analysis showed that independent risk factors were wound type,anesthesia type, open fracture,time from injury to operation,and duration of operation,OR(95% CI)were 12.47(2.78-15.88), 11.55(2.84 - 17.02),10.79 (2.72 - 11.13 ),2.35 (2.12 - 6.81 ),and 3.07 (1.88 - 4.13 )respectively. Conclusion Risk factors for SSI following limb fracture surgery are multiple,the key to the prevention and control of SSI are identifying risk factors and strengthening the management of key points.

Objective To explore the changes and clinical significance of iron metabolism indexes such as serum ferritin (sFn),serum transferritin (sTf),serum transferritin receptor (sTfR) in patients with hematologic malignant disease before and after treatment.Methods Fifty-nine patients with hematologic malignant disease were enrolled.We measured the blood routine,bone marrow routine and iron bound of bone marrow cells and sFn、sTf、sTfR before and after treatment.The control group was 43 healthy Volunteers.Result Before treatment the level of patients sFn increased obviously,which was higher than that of control significantly (P ＜ 0.05).After chemotherapy,the level of sFn in remission group decreased obviously,which was still higher than that of normal control.sFn expression in non-remission group was not different from that before therapy or normal control (P ＞ 0.05).The level of sTf was lower than that of control significantly pretreatment and aftertreatment (P ＜ 0.05).While there was no different between remission group and nonremission group after chemotherapy (P ＞ 0.05).The level of sTfR in non-remission group after chemotherapy was higher than that of control.Correlation analysis showed that there was positive correlation between the serum level of sFn and the original and naive bone marrow cells (r =0.347).And there was negative correlation between sFn and hemoglobin (r =-0.207).But there was no significant correlation between sFn and bone marrow iron.Conclusions It is possible to predict treatment response and prognosis in hematologic malignant disease by the decrease of sFn after chemotherapy.But sTf and sTfR are not good indexes to predict treatment response in a short time.Prevalence of anemia among patients with tumor was not only because of iron deficiency.So iron supplementation should be cautious.
