Objective To explore the expression of the mRNA level of Fas (CD95) ligand/FasL and Fas-associated phosphatase-1/FAP-1 in acute myeloid leukemia. Methods The expression of FasL and FAP-1 were detected in 54 patients with AML and 10 normal subjects by semi-quantitative reverse transcriptase-polymerase chain reaction (RT-PCR). β-actin used as internal reference. The changes of FasL was observed after induction chemotherapy in 16 AML patients. The expression of Fas was detected in 54 patients with AML by flow cytometry. Results The mRNA levels of FasL and in 54 patients were remarkably higher(P <0.05) than the normal controls. The rates of first complete remission(CR) were significantly higher in FasL(+) (77.78 %) than in FasL(-) cases(16.67 %) (P<0.01). The FasL level declined in 10 patients with good response to therapy (P<0.01), and high level in 6 nonresponding patients with poor response (P>0.05). The mRNA levels of FAP-1 in 54 patients was remarkly higher than that of the normal control. 8/29 cases in Fas-positive group were positive for FAP-1 mRNA expression. 19/25 cases in the Fas-refractory group didn't express FAP-1 mRNA. Conclusion The expression of FasL was high in AML. The rates of complete remission were high in FasL positive cases. The FasL level declined in patients with good response to therapy. The expression of FAP-1was partly expressed in AML. The expression of FAP-1 was less in Fas positive group.

Objective To explore the clinical characteristics of poststroke epilepsy and to discuss the association with the type of stroke,the location of focus.Methods Clinical information of 64 patients with poststroke epilepsy taken from 932 patients with stroke were analyzed retrospectively.Results In the patients with first stroke,the incidence of poststroke epilepsy was 6.9％.Among them,47 cases belong to early seizure (73.4％) and 17 cases belong to late seizure (26.6％).The incidence of poststroke epilepsy was difference between ischemic stroke and hemorrhagic stroke.There were more cases of stroke in cortical focus than subcortial one.Onset seizures type was more cases of partal seizure than generalized tonic-seizure (GTS).The treatment on early seizure could be short-range treatment and the treatment on late seizure should be long-term standardized treatment and regular.Conclusions Occurrence of poststroke epilepsy were involved in the type of stroke,the location of focus (cortex / subcortex).It is helpful for guiding the clinical therapy of patients with stroke and improving the quality of their life to analyse the clinical characteristics of poststroke epilepsy.

Objective To explore sleep quality and mental health status of chronic obstructive pulmonary disease(COPD) patients with respiratory failure.Methods From October 2015 to June 2016,COPD patients with respiratory failure hospitalized in our hospital were selected as study group.Patients without COPD hospitalized in our hospital were selected as the control group.The sleep quality and mental health were compared between the two groups.Results The age and body mass index (BMI) between the two groups showed no significant difference (t =0.753,0.693,all P ＞0.05).The forced expiratory volume in one second (FEV1％) expected value,arterial oxygen pressure (PaO2),oxygen saturation (SaO2) in the study group were (52.34 ± 12.25) ％,(9.21 ± 1.83) mmHg,(90.36 ± 3.47) ％,which were significantly lower than those in the control group,the differences were statistically significant (t =25.199,5.414,16.439,all P ＜ 0.01).The somatization,obsessive-compulsive symptoms,interpersonal sensitivity,depression,anxiety,terror between the two groups had significant differences (all P ＜ 0.05),the differences in hostility,paranoia and psychosis were not statistically significant (all P ＞ 0.05).The quality of life scale (GQOL-74) scores in cognitive function [(74.47 ± 6.13) points],psychological function [(71.28 ± 7.36) points],physical function [(73.73-± 8.85) points] and social function [(74.35 ± 7.18) points] in the study group were significantly lower than those in the control group,the differences were statistically significant (t =9.735,13.972,5.739,10.040,all P ＜ 0.01).Conclusion The sleep quality and mental health status of COPD patients with respiratory failure is poorer,we should pay more attention and intervention in clinical diagnosis and treatment.

0.05).[Conclusion]Lateral-anterior fixation with use TSRH not only has effective result in strength, rigidity and stability of the spine, but also is superior to the control group in loading-bearing ability and stability of the spine. There is no significant difference between the TSRH group and Z-plate group. But TSRH is relatively simple to operate and is cheaper than Z-plate, and has exact clinical ontcome.

In order to investigate the effect of deep brain stimulation on diseases such as epilepsy, we developed a closed-loop electrical stimulation system using LabVIEW virtual instrument environment and NI data acquisition card. The system was used to detect electrical signals of epileptic seizures automatically and to generate electrical stimuli. We designed a novel automatic detection algorithm of epileptic seizures by combining three features of field potentials: the amplitude, slope and coastline index. Experimental results of rat epileptic model in the hippocampal region showed that the system was able to detect epileptic seizures with an accuracy rate 91.3% and false rate 8.0%. Furthermore, the on-line high frequency electrical stimuli showed a suppression effect on seizures. In addition, the system was adaptive and flexible with multiple work modes, such as automatic and manual modes. Moreover, the simple time-domain algorithm of seizure detection guaranteed the real-time feature of the system and provided an easy-to-use equipment for the experiment researches of epilepsy control by electrical stimulation.
