Objective To explore the measures for nursing patients with acute hepatic graft versus host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation. Method The clinical data of 54 patients with aGVHD after hematopoietic stem cell transplantation during January 2010 and December 2013 were reviewed for summing up the nursing measures. Results In the study, 160 patients underwent allogeneic-hematopoietic stem cell transplantation and 53 of them contracted with acute hepatic-versus-host disease. Among them, 2 cases were at degreeⅣ, 10 at degreeⅢ, 23 at degreeⅡand 19 at degreeⅠ. Forty-seven cases(87.01%) were cured after careful treatment and care , 3 ( 5 . 56%) developed into cGVHD and 4 ( 7 . 41%) died . Conclusion Enhanced observation and postoperative nursing of liver, intestine and skin together with performance of mental care and dietary nursing are effective in achieving satisfactory outcomes of GVHD.

Journal of International Pharmaceutical Research 2010;37(4):302-309
Objective: To establish the high-throughput screening system for β-secretase (β-site amyloid precursor protein cleaving enzyme 1, BACE1) inhibitors in vitro. Methods: Using the homogeneous time-resolved fluorescence (HTRF) technique to establish a high-throughput screening system for BACE1 inhibitors according to the extent that test compounds inhibited BACE1 activity by optimizing the incubation time, enzyme concentration and the detector. Results: A high-throughput screening system for BACE1 inhibitors based on HTRF methods was established. The incubation time was 6 h, the BACE1 concentration is 670 U/L. According to the detector of VICTOR3, the signal-to-noise (S/N) ratio reached 649.6, while the signal-to-background (S/B) ratio and Z′ factor were 44.6 and 0.91, respectively. The coefficient of variation (CV) was much lower than 10%. Using this method, the inhibitors with IC50<106mol/L could be screened out. Conclusion: The high-throughput screening system based on HTRF Could assure a high sensitivity, specificity and stability, which could be used to high-through put screening for the BACE1 inhibitors.

Objective To improve treatment success rate and prognosis for patients with bifrontal contusions by intracranial pressure monitoring.Methods A retrospective analysis was conducted on 79 cases of bifrontal contusions admitted between October 2004 and April 2012.The patients were divided into intracranial pressure monitoring group (n =40) and group without intracranial pressure monitoring (n =39),according to the treatments.Significance of high coronary craniotomy timing,surgical strategy and intracranial pressure monitoring in the diagnosis,treatment and prognosis was analyzed.Results The intracranial pressure monitoring group showed a significantly shorter period concerning osmotic dehydration [(14.24 ± 7.93) days vs (21.61 ± 11.97)days,P<0.01],ICU stay [(14.38 ±7.56)days vs (24.71-± 17.94)days,P<0.01] and total hospital stay [(17.20 ±8.09)days vs (33.92 ± 21.70)days,P<0.01] as well as a better GOS [(4.15 ± 1.22) points vs (3.69 ± 1.56) points,P < 0.05],as compared with group without intracranial pressure monitoring.Conclusions Craniotomy,especially decompressive craniectomy,is one of the most important treatment means to control cranial pressure and ensure cerebral perfusion pressure in patients with bifrontal contusions (in particular the moderate and severe ones).Besides,intracranial pressure monitoring is conducive to selection of surgery timing and is instructive to combined treatment,such as osmotherapy,intracranial pressure controlling and assurance of cerebral perfusion pressure.

Objective To analyze the suspicious results of serum HBV DNA by fluorescence quantitative PCR and develop appropriate countermeasures in order to improve the quality of detection of HBV DNA.Methods Blood samples of patients from the First Affiliated Hospital of Wenzhou Medical College from 2008 to 2011 were analyzed for HBV DNA by fluorescence quantitative PCR.1969 cases of suspicious results,judged by the rule of review the results of serum HBV DNA combined with the historical results,PCR amplification curve,HBV serum markers and clinical diagnosis,were analyzed and redetected by using of two different reagents,careHBV PCR Kit and careHBV PCR Kit V2,at the same time.The consistency and inconsistency ratio of the results were evaluated.Both the reasons of inconsistent and the undetected rates of careHBV PCR Kit were analyzed.The two reasons for the inconsistent results included the reagent related factors,e.g,showing no amplification curve caused by the false negative and abnormal low efficiency of amplification curve,and the non reagent related factors such as operating pollution and other sample factors.Results There were 115 154 blood samples were detected for HBV from 2008 to 2011 and 1969 samples (1.71%) with suspicious results were redetected.The consistency and inconsistency results were 1588 (80.65%) and 381 (19.35%),respectively.Every year from 2008 to 2011,the percentage of the inconsistent results caused by the reagent related factors were 18.87%,20.23%,51.33% and 59.57% respectively,which showed an increasing trend,and the percentage of inconsistent results caused by the nonreagent related factors were 81.13%,79.77%,48.67% and 40.43% respectively,which showed a declining trend year by year.The undetected rates of careHBV PCR Kit were 2.49%,4.08%,10.09% and 14.47% respectively,showing an increasing trend.Conclusions The redetection for the specimens with the suspicious results by using of different reagents can avoid the blind detection of HBV DNA and reduce the experimental error.All the clinical samples for quantitative HBV DNA including the mutations of HBV gene can be measured accurately and effectively,which is helpful to hepatitis B patients for antiviral therapy.

Objective To explore a new training method of nursing skills under 24 hours shift system in the practical training base in the college. Methods The practical training base in the college was rebuilt into a simulated hospital. 120 three-year-course nursing students in grade 2007 were divided into the control class and the experimental class with 60 students in each class. The control class adopted routine teaching method, including teacher demonstration, single project training, concentrated training before clinical practice. The experimental class participated in the tutoring mode of nursing skills under 24 hours shift system in simulated hospital. The cases were pre-designed and students acted as patients by tums. One teacher led 4 students into nursing skill training by day shift, evening shift and mid-night shift. The teaching effect was compared between two classes. Results There was significant difference between the two groups in comprehensive technique test and graduation theoretical test score. Clinical nursing teachers thought the skill training in simulated hospital under 24 hours shift system can help students prepare for the nursing work in hospital ahead of time and improve their comprehensive capability. Conclusions Training mode of nursing skills in simulated hospital under 24 hours shift system is feasible for enhancing nursing skills.

DNA repair processes play a role in the development of drug resistance which represents a huge obstacle to leukemia chemotherapy.Histone H2AX phosphorylation (ser139) (γH2AX) occurs rapidly at the onset of DNA double strand break (DSB) and is critical to the regulation of DSB repair.If DNA repair is successful,cells exposed to anti-neoplastic drugs will keep entering the cycle and develop resistance to the drugs.In this study,we investigated whether γH2AX can be used as an indicator of tumor chemosensitivity and a potential target for enhancing chemotherapy.K562 and multi-drug resistant cell line K562/A02 were exposed to adriamycin (ADR) and γH2AX formed.Flow cytometry revealed that percentage of cells expressing γH2AX was increased in a dose-dependent manner and the percentage of K562/A02 cells was lower than that of K562 cells when treated with the same concentration of ADR.In order to test the potential of γH2AX to reverse drug resistance,K562/A02 cells were treated with PI3K inhibitor LY294002.It was found that LY249002 decreased ADR-induced γH2AX expression and increased the sensitivity of K562/A02 cells to ADR.Additionally,the single-cell gel electrophoresis assay and the Western blotting showed that LY249002 enhanced DSBs and decreased the expression of repair factor BRCAl.These results illustrate chemosensitivity can partly be measured by detecting γH2AX and drug resistance can be reversed by inhibiting γH2AX.
