Objective To investigate the easement degree of pain after the treatment of low back pain patients in 6 months after the operation.Methods To treat lumbar degenerative osteoarthritis (21cases),lumbar disc herniation(31 cases),Lumbar spinal stenosis assompanied with lumbar disc herniation(1 cases) with percutaneous radiofrequency-ablation,compare the JOA,VAS,Oswestry score of the patients before and at the just after operation,2 weeks,6weeks,3 months,6 months after operation.Results The JOA score of patients after operation rise obviously than that of patients before operation,and VAS and Oswestry score reduce obviously,they all have statiscal significance(P ＜ 0.05).Conclusion The pain of patients who suffered from discogenic low back pain,lumbar disc herniation is relieved by percutaneous radiofrequency-ablation,the quality of patients'life is heightened,all of above indicate that the treatment is an effective method for discogenic low back pain,lumber disc herniation.

There is great role of position treta ment in critically paediatric patient.It can not only alleviate the ol cal skin contracture opprse sion,muscle joints,but can cause the redistribution of body fluids. Even changing body position plays a crucial role in a number of specific diseases and treatment modalities. Intensive care unit common position includes seated,semi-seated,supine,semi-supine,left lateral, right lateral op sition na d prone position,anti-trendelenburg position,continuous lateral rotation therapy.The following is a brief introduction to the application of various body positions in the intensive care unit.

There is a great progress in research related to the lung stem cell which is one kind of somatic stem cells in recent years.This article reviewed systematically the lung stem cell biological characteristics,the surface markers,migration,homing,and the clinical application in the treatment of acute respiratory distress syndrome.

ObjectiveTo observe the effect of early rehabilitation on patients with acute severe brain injury.Methods180 cases with acute severe brain injury were tr eated with early rehabilitation measurements consisted of breath rehabilitation,passive activity of joints in range of joint motion, body posture change,preve ntion of the lower urinary tract infection, and rehabilitation with Traditional Chinese Medicine,etc.Results18 patients (8.3%) co mplicated infection of lungs during the acute stage, no patient died of complica tions.Conclusions The early rehabilitation can pre vent patients with severe brain injury from complications and improve the effica cy of the treatment.

Objective To find out the expression relation between TP53 and NOTCH1,and to explore their effects in head and neck squamous cell carcinoma.Methods Obtained the differentially expressed genes data of head and neck squamous cell carcinoma from 279 samples in TCGA database.Analyzed the co-expression relation between TP53 and NOTCH1 through Pearson and Spearman method.Cbioportal was used to analyze their co-expressed genes.Establish the co-expression network of TP53 and NOTCH1 with String database.The pathway and function of co-expression network was identified through KEGG and DAVID database respectively.Results Among the 279 samples,TP53 and NOTCH1 was co-expressed in head and neck squamous cell carcinoma.(Pearson score =0.45;Spearman score =0.41) There were 182 interaction pairs of TP53 and NOTCH1 related co-expressed gene according to the String database.(Pearson and Spearman score ＞ 0.3)These genes were enriched in some pathways such as T cell receptor signaling pathway,cell cycle,cell adhesion molecules and so on.These genes were enriched in some tumor related function including immune response,regulation of transposition,regulation of apoptotic process,cell cycle,regulation of GTPase activity and so on.Conclusion TP53 and NOTCH1 was co-expressed.Through establishing co-expressed network of TP53 and NOTCH1 and bioinformatics analysis,their function and signaling pathway were explored.The data generated from this study could provide a new reference in mechanism research of head and neck squamous cell carcinoma.

Objective To evaluate the outcome and safety of endoscopic submucosal dissection (ESD) versus endoscopic mucosal resection (EMR) in the management of esophageal mucosal lesion.Methods The clinical data of 70 patients with esophageal mucosal lesion were analyzed.Twenty-five patients were treated by ESD (ESD group) and 45 patients were treated by EMR (EMR group).The enbloc resection rate,tissue healing resection rate,operation time,complication and recurrence rate were compared between two groups.Results The enbloc resection rate,tissue healing resection rate in ESD group were significantly higher than those in EMR group [60.0％(15/25) vs.48.9％(22/45),48.0％(12/25) vs.40.0％ (18/45)] (P ＜0.05).The local recurrence rate in ESD group was lower than that in EMR group [4.0％ (1/25) vs.20.0％ (9/45)] (P ＜ 0.05).The severe complication such as delayed hemorrhage,perforation,stenosis between two groups had no significant difference (P ＞ 0.05).The operation time in ESD group was (64.3 ±27.1) min,and significantly longer than that in EMR group [(27.6 ± 14.1) min] (P ＜0.05).Conclusions Compare with EMR,ESD has better enbloc resection rate,tissue healing resection rate,and lower recurrence rate.It is more safe and effective in the therapy of esophageal mucosal disease.

Objective To explore the influence on cyclin and cyclin-dependent kinase inhibitor of cell cycle of Kasumi-1 cell-derived from t(8;21)/AML treated with histone deacetylase(HDAC)inhibitor valproic acid(VPA).Methods RT-PCR assay was applied to detect mRNA expression of regulation factor of cell cycle of Kasumi-1 cell with VPA at different concentration and different time. Results VPA could down-regulate mRNA expression of cyclinD1,cyclinE1 and cyclinB1,and up-regulate mRNA expression of p21 WAF1/CIP1 with no obvious variation of mRNA level of p27KIP1. Condusion VPA could regulate cell cycle through the regulation of cyclins and cyclin-dependent kinase,arresting Kasumi-1 cell at G0/G1 phase.

In this paper, we generalized the basic concept of ability health management and discussed its core connota -tion in terms of ability health measurement , ability health assessment and ability training .After defining ability health meas-urement, outlined the process of determining the measurement items and listed the main contents of measurement standardi -zation.Further, we systematically analyzed the basic components of ability health assessment , including the index system , standards, methods and process .We also discussed the function , classification and principle of ability training .Finally, we drew the conclusion that the goal of ability health management is to improve the ability health level so as to consolidate and promote the operation capability of military personnel .
