The recently published papers about donor cell-derived leukemia after umbilical cord blood transplantation and related data were reviewed, while the mechanism of leukemia and related problems of umbilical blood conservation were discussed. In view of the possibility of prenatal origin of leukemia, it is necessary to more systematically check the leukemia relapse cases after umbilical cord blood transplantation for exactly identifying the frequency of donor cell derived leukemia and to determine whether the transfer of pre-leukemic clones is indeed present.

Objective To explore the before taking finasteride on transurethral plasmakinetic resection of prostate(TUPKVP)patients about IPSS,QOL,Qmax,PVR and other indicators.Methods 180 cases with benign prostatic hyperplasia were randomly divided into observation group and control group,90 cases in each group.Observation group and control group were given conventional therapy and the observed patients took 5 mg of finasteride everyday one week before surgery,all patients were followed up for 1 month.The two groups of TUPKVP patients were compared about IPSS,QOL,Qmax and PVR,intraoperative blood loss,operation time,irrigation fluid volume indicators.Results 180 patients were given successfully TUPKVP surgery.IPSS,QOL,Qmax and PVR contrast were significantly improved after treatment(t=5.11,7.01,3.06,6.17,11.82,4.13,4.52,5.17,all P＜0.05).IPSS,Qmax,PVR of the observation group after treatment was significantly better than that of the control group(t=11.35,5.26,3.12,all P＜0.05),the QOL difference between the two groups after treatment was not statistically significant(P＞0.05).The cure rate of the observation group was 87.8％,which was significantly higher than 63.33％ in the control group(x2=14.56,P＜0.05).Intraoperative flushing fluid volume,intraoperative blood loss,duration of surgery in the observation group were significantly different compared with the control group,(t=21.15、43.12,5.33,all P＜0.05).Conclusion The preoperative taking finasteride can reduce TUPKVP blood loss and flushing fluid volume,shorten operation time and effectively improve the security of the operation.

Objective To investigate the moderator of children' s perceptions quality of parental involvement on parenting style and children' s sport expectancy-value beliefs.Methods 595 students of grade 2 to 6 from five elementary schools were chosen and analyzed.Data were analyzed by SPSS16.0 software packet using independent sample t test,One-Way ANOVA,correlation analysis and hierarchical regression statistical analysis of regulation.Results Children' s expectancy beliefs was predicted by authoritarian and behavior encouragement(β=0.076,t =2.35,P=0.019 ;β =0.111,t =3.748,P =0.000).Children' s value beliefs was predicted by affect -warmed and behavior encouragement (β =0.070,t =2.883,P =0.004 ;β =0.070,t =2.745,P =0.006).Children' s sport behavior was predicted by trust-encouragement(β=0.294,t=3.193,P=0.001).The prediction of expectancy beliefs was significant positive by the interaction between indulgence and time involvement (β=0.078,t =2.065,P =0.039).The prediction of expectancy beliefs was significant negative by the interaction between authoritarian and time involvement(β=-0.084,t =-2.454,P=0.014).The prediction of expectancy beliefs was borderline significant positive by the interaction between neglecting and equipment provision(β=0.073,t =1.94,P =0.053).Conclusion Different parenting styles are significant predicators of children sport involvement.Children' s perceptions quality of parental involvement play an important role on parenting style and children' s sport expectancy-value beliefs.

[Objective] To evaluate the value of Fulcrum-bending radiograph and new treatment strategy to the scoliosis with Chiari malformation and/or syringomyelia,and to analyze the effect of operation.[Methods]Eighteen cases suffering from scoliosis with Chiari malformation and/or syringomyelia were divided into 2 groups for surgical treatment.(1)Group 1:six cases had scoliosis with Chiari malformation and/or syringomyelia without obvious neurological impairment.Their scoliosis was corrected with anteroposterior instrumentation afer one week of Halo's traction.(2)Group 2:another 12 patients having similar scoliosis underwent posterior orthopedic operation according to the result of preoperative suboccipital Fulcrum-bending radiograph.[Results]In 6 patients who underwent opration after traction,the average frontal correction rate was 61%.In another 6 cases having soft scoliosis with only posterior operation,the average frontal correction rate was 60%,and the result of opration came close to the Fulcrum-bending radiograph's.But in 6 cases having rigid scoliosis with only posterior operation,the average frontal correction rate was 52%.One patient had nervous lesion and gradually recovered.There existed excessive rectification.[Conclusion]Patients with soft scoliosis with Chiari malformation and/or syringomyelia without obvious neurological impairment can be operated on according to Fulcrum-bending radiograph without preoperative traction,and the therapeutic effect is similar to classic operative result.

OBJECTIVE: To investigate the possible beneficial effects of administration of Naoluo Xintong Recipe (NLXT) on the expression of HSP70 and bFGF in rats subjected to ischemia-reperfusion with qi deficiency and blood stasis syndrome. METHODS: We blindly randomized 40 male Wistar rats into 5 groups which were categorized as follows: (1); sham-operated group; (2) rats subjected to transient middle cerebral artery (MCA) occlusion with qi deficiency and blood stasis syndrome (control group); (3) NLXT-treated group; (4) NLXT-pretreated group; (5) Nao'an Capsule-treated group. Focal brain ischemia was induced by the intraluminal suture MCA occlusion method after qi deficiency and blood stasis syndrome had been made. The rats' brains were harvested at the 24h of reperfusion after 2h of MCA occlusion. The expression of HSP70 and bFGF was measured by by immunohistochemical staining. RESULTS: Strong HSP70 immunoreactivity in neurons was observed in NLXT-treated and NLXT-pretreated groups as compared to control group, and increased bFGF immunoreactivity in neurons was observed in the ischemic hemisphere in NLXT-pretreated group in comparison with the ischemic hemisphere in the control group (P<0.01). NLXT has stronger effects on HSP70 and bFGF than Nao'an Capsule. CONCLUSION: The neuroprotective effects of Naoluo Xintong Recipe may be related to its up-regulation of HSP70 and bFGF in the rat brain after focal cerebral ischemia.

In critically ill patients,evoked potential(EP) testing is an important tool for measuring neurologic function,signal transmission,and secondary processing of sensory information in real time.EP potential measures conduction along the peripheral and central sensory pathways with longer-latency potentials representing more complex thalamocortical and intracortical processing.In critically ill patients with limited neurologic exams,EP provides a window into brain function and the potential for recovery of consciousness.Brainstem auditory EP and cortical event-related potentials are most commonly used in ICU.The primary indications for EP in critically ill patients are prognostication in anoxic-ischemic or traumatic coma,monitoring for neurologic improvement or decline,and confirmation of brain death.Historically,EP has been regarded as a negative prognostic test,that is,the absence of cortical potentials are associated with poor outcomes while the presence cortical potentials are prognostically indeterminate.In recent studies,the presence of middle-latency and long-latency potentials as well as the amplitude of cortical potentials is more specific for good outcomes.Event-related potentials,particularly mismatch negativity of complex auditory patterns,is emerging as an important positive prognostic test in patients under comatose.In infants,other than anoxic-ischemic or traumatic brain injury,brainstem auditory is also widely used in premature baby,bilirubin encephalopathy and detection of possible hearing loss.

OBJECTIVE: To evaluate the utilization and its trend of narcotic analgetics in this hospital.METHODS: The use of narcotic analgetics during the period 2005-2007 in our hospital was analyzed retrospectively.RESULTS: The consumption quantity of narcotic analgetics in our hospital increased year-on-year,much as in the consumption of morphine preparations,with oral morphine preparations dominating the 3 first places over the 3 years,however,the increase of pethidine was slowed down in consumption quantity.CONCLUSION: The use of narcotic analgetics in our hospital is rational on the whole,but measures should be taken to tighten the control on the use of narcotic analgetics.
