ABSTRACT
The effective treatment methods of myelodysplastic syndromes (MDS) are limited. The patient's treatment plan is mainly based on individual differences and different risk levels [by revised International Prognostic Points System (IPSS-R)], including observation, erythropoiesis stimulating agents, iron elimination, immunosuppressive agents, lenalidomide, hypomethylating agents and hematopoietic stem cell transplantation (HSCT). The limitations of the treatment strategies are important exploration directions for future clinical trials. At present, multiple clinical trials for the treatment of MDS are underway, but it is still necessary to optimize therapies through integrating molecular and genetic data and applying them to clinical practice. This article reviews the current treatment approaches of MDS and looks forward to future research directions.
ABSTRACT
Objective To translate English version of sensory-motor profile awake ( SMP-a) into Chinese version (the Chinese Version of SMP-a),and analyze the reliability and validity of the scale before and after craniotomy under awakening anesthesia. Methods Eighty-one patients whose tumors were located near or already in sensory-motor functional area were included in this study. Before and after awake cranioto-my,the Chinese version of SMP-a was used to accurately assess the sensory-motor function of each patient. Finally, the reliability and validity of the scale were analyzed by SPSS statistical software. Results Cronbach's α coefficient in the Chinese version of SMP-a was 0. 971,and Cronbach's α coefficient in the four subscales of face,hand,leg and sensation was 0. 965,0. 989,0. 981 and 0. 970,respectively. The test-retest reliability of the Chinese version of sensorimotor assessment scale was 0. 910,0. 904,0. 884,0. 898 and 0. 695 (total,face,hands,legs and sensory score respectively). The raters' consistency reliability was above 0. 949,0. 960,0. 934,0. 887 and 0. 660,respectively. The Pearson correlation coefficients of sensorimotor function score with SF-36 physiological function factors and KPS score were 0. 868 and 0. 790,respectively. Conclusion Before or after operation,the Chinese version of SMP-a has preferable reliability,internal con-sistency reliability and structural validity. It is feasible in awakening anesthesia craniotomy,and the degree of damage can be determined by repeated measurement of the sensorimotor sites that may be impaired by the patient.
ABSTRACT
Objective To investigate the clinical value of vitamin D receptor ( VDR) gene polymorphism in lung cancer screening .Methods From January 2017 to September 2017 ,2000 lung cancer screening patients in the Fifth People's Hospital of Foshan were selected in the research .The VDR gene polymorphism was determined by phenol-chloroform method .DNA was extracted from the peripheral blood of patients ,different VDR genotypes [ Bsm1 bb and Bb),Apal(aa,Aa and AA)] were analyzed by univariate analysis to determine the correlation between lung cancer and VDR gene polymorphism and lung cancer incidence by multivariate non -conditional logistic regression analysis, thus to explore the relationship between different VDR genotypes and risk factors of lung cancer . Results The level of serum vitamin D in the non -lung cancer patients was (46.5 ±2.3) ng/L,which was signifi-cantly higher than (26.5 ±1.1)ng/L in the lung cancer patients (t=49.614,P=0.000).The Bsm1bp genotype, Apal aa genotype and Apal Aa genotype were the risk factors of lung cancer .The Bsm1bp and Apal Aa genotypes were independent risk factors of lung cancer .Conclusion The Bsm1 locus and Apal locus Aa genotype in VDR receptor are high risk population of lung cancer .Therefore,we should pay more attention to the clinical screening and avoid misdiagnosis and missed diagnosis .
