Extramedullary infiltration is one of the reasons of relapse and death for leukemia patients.Reaearches increasingly show that extramedullary microenvironment plays a pivotal role on progress and relapse of leukemia.Extramedullary infiltration of leukemia is the result of interactions among many factors and many steps,involving liver,spleen,central nervous system,thymus and other tissues and organs.

Objective:To observe therapeutic effect of Fufang Cangzhu Decoction on senile obesity or overweight with impaired glucose tolerance(IGT).Methods:32 cases of senile obesity or overweight with IGT were treated by Fufang Cangzhu Decoction and 32 cases by dimethyldiguanide as controls.Changes of body weight,waist circumference,hip circumference,waist hip circumference ratio(WHR),glucose tolerance,fast serum insulin and blood lipid before and after treatment were compared.Results:After treatment,body weight,waist circumfereince,hip circumference and WHR,glucose tolerance,blood glucose and fast serum insulin ,blood lipids in the Fufang Cangzhu Decoction treatment group decreased significantly(P0.05).Conclusion:Fufang Cangzhu Decoction can obviously decrease body weight,waist circumference,hip circumference and WHR,blood glucose,fast serum insulin,blood lipids in the senile patient of obesity or overweight with abnormal glucose tolerance.

Objective To find out some ways to solve the problems which are dealing with the clinical application of intrafix.Methods From February to May 2013,324 patients with back blood using intrafix in emergency department were randomly assigned to the experimental group A and the control group A,with 162 patients in each group.The experimental group A used the method of pressing pipe while pulling out the needles when transfusion was over,while the control group A used traditional ways.206 patients who occurred bubbles in the intrafix among the above two groups were divided into the experimental group B and the control group B.The experimental group B got rid of the bubbles using top-down method,the control group B used traditional ways.The effect of withdrawing the needles and exhaustion of bubbles were compared.The least flushing time of remaining liquid using transfusion pipe flushing method was calculated.Results The experimental group A and the experimental group B were better in withdrawing the needles and exhaustion of bubbles compared with those of the control group A and the control group B.Using the method of drop coefficient to calculate the least flushing time can ensure the drug to be transfused into the body thoroughly.Conclusions When transfusion is over,pressing intrafix pipe will have a better result than the traditional way when pulling out the pipe.Top-down method can clearly settle the problem of intrafix pipe,which can not get rid of bubble via traditional way.Flushing pipe and press pipe method can apparently decrease drug waste.

OBJECTIVE To investigate the generation of beta-lactamases from Klebsiella pneumoniae(KPN) which is only susceptible to imipenem.METHODS Sixteen kinds of beta-lactamase genes were detected in a KPN strain by PCR.The genes included TEM,SHV,LEN,OKP, CTX-M-1 group,CTX-M-2 group,CTX-M-9 group,OXA-1 group,OXA-2 group,OXA-10 group,PER,GES,VEB,CARB,DHA,and ACT-1.RESULTS The assay showed six positive genes including TEM,SHV,CTX-M-1 group,CTX-M-9 group,OXA-1 group,and DHA.CONCLUSIONS The KPN strain carries six kinds of beta-lactamase genes simultaneously.

Objective To investigate the relationship between the changes of serum total bilirubin(TBil) and hybrid muscle crea-tine kinase isozyme(CK-MB),and its clinical implication in neonates with hypoxic-ischemic encephalopathy (HIE). Methods The levels of TBil and CK - MB were measured in 49 neonates with HIE (15 mild cases, 20 moderate cases and 14 serious cases), and 31 normal neonates on the first day and the fourth day after birth. Results The levels of TBil on the first day after birth were significantly higher than those in normal neonates;the levels of TBil were correlated with the severity of HIE(P

This paper introduces the principles of an Environmental Temperature Supervising Network System, explain its hardware and software structure and the function of network system. The whole system is proved stable and reliable by experiment. It may have some profit in the market and great future in the application.

Objective To study the clinical significance of end-tidal carbon dioxide partial pressure (PetCO2 ) during cardiopulmonary resuscitation (CPR) and seek the fixed value according which to decide if we should and when to give up.Methods This was a prospective,observational study.A total of 124 patients with cardiac arrest in or out-of-hospital from may 2003 to March 2009 in emergency department of our hospital were selected.All of them had definite etiological factors.Changes of PetCO2 in 124 cardiac arrest patients during CPR were tracked.Results The gender,age,rescue time in seventy-one patients with the return of spontaneous circulation (ROSC) after endotracheal intubation have a significant difference with that in fifty-three patients without ROSC (P ＜0.01 ).The PetCO2 of the survival were higher than that of patients without ROSC or with ROSC,but finally died (P ＜0.01 ).A fixed point 14.4 mmHg of PetCO2 after 20 minutes' CPR can be used as a reference value to guide CPR or predict prognosis.Conclusions Monitoring PetCO2 during CPR has a predictive value on the success of resuscitation.

BACKGROUND:The treatment of infected nonunion is a difficult problem in orthopedic trauma, which needs to completely eliminate foci of osteomyelitis to control infection, repair soft tissue defect and close the wound, repairs bone defects to promote healing and protect limb function as much as possible. Autogenous micromorselized bone can be easily obtained and recombinant human bone morphogenetic protein-2 has variety of sources. Their mixed grafting mode is safe and reliable in repairing of bone defects, which are suitable for repair of infected nonunion. ＜br> OBJECTIVE:To study the operating method and clinical results of repairing infected nonunion using autogenous micromorselized bone grafting mixed with bone morphogenetic protein-2. ＜br> METHODS:Twenty-three cases underwent infected nonunion repair with autogenous micromorselized bone (l ium, long bone metaphyseal cancellous bone) mixed with bone morphogenetic protein-2, including 7 cases of femoral bone defect caused by osteomyelitis after debridement and external fixation and 16 cases of tibial bone infected nonunion. Eleven of 23 cases continued to use the external fixation because of scar contraction or poor conditions of soft tissue, and the other 12 cases switched to use internal fixation. X-tray was taken to evaluate the bone healing at the 1st, 3rd, 6th and 12th months after operation. The function of the affected extremity was assessed by Johner-Wruhs grade. ＜br> RESULTS AND CONCLUSION:Al of the cases were averagely fol owed up for 13.4 months. The bone defects and bone fracture healed in al cases without infection, and the wounds were al sealed. The excellent and good rate according to Johner-Wruhs grade was 95%. These findings indicate that the bone grafting mode of autogenous micromorselized bone mixed with bone morphogenetic protein-2 is characterized as variety of sources, high safety and reliable osteogenic ability in repair of bone defects.
