Through learning philosophy,human beings can overcome the fear of death and gain the wisdom of life.With the rapid development of modem high-tech,some people advocate to pursue the immortality of individual life using science and technology.This is the most restless thoughts,originating from the false belief of dogmatic rationalism:with the development of science and technology,human beings are possible to fully grasp the mysteries of the nature (including human body).In fact,nature as well as human body is always hidden in infinite mystery.The pursuit of immortality is from the pursuit of meaning.Setting up morality,making contribution,and achieving glory by writing are the legitimate ways for human beings to pursuit immortality as cultural animals.One just can pursue immortality in the cultural sense,but cannot pursue the immortality of individual life.

Objective To study the correlation between human leukocyte antigen (HLA)-DRB1 alleles and anti neutrophil cytoplasmatic antibodies (ANCA) in Han and Uygur ulcerative colitis (UC)patients in Xinjiang region.Methods The serum ANCA was determined by indirect immunofluorescence assay in 62 Uygur UC patients,58 Han UC patients,188 Uygur and 184 Han healthy control individuals.HLA-DRB1 typing was performed by polymerase chain reaction-sequence based typing (PCR-SBT).The allele frequency of HLA-DRB1 was compared in ANCA positive and negative Han and Uygur patients as well as healthy controls.Stratified analysis was performed according to UC clinical type,severity and involvement.SPSS 17.0 software was applied for x2 test.Once P＜0.05,the odds ratio (OR) and 95％ confidence intervals (95％CI) was calculated.Results The positive rate of ANCA in Uygur UC patients (53.2％,33/62) was significantly higher than that of Han patients (34.5％,20/58) and the difference was statistically significant (x2=4.269,P =0.045).In Uygur,the gene frequency of HLA-DRB1 * 13 in ANCA positive UC patients (0.202)was significantly higher than that of ANCA negative patients (0.017) (x2 =10.092,P=0.016,OR=16.000,95％CI:2.892 to 88.524) and healthy controls (0.075) (x2=9.351,P＝0.040,OR=3.407,95％CI:1.666 to 6.971).The gene frequency of HLA-DRB1 * 13 in ANCA positive pancolitis type UC patients (9/15) was significantly higher than that of ANCA negative pancolitis type UC patients (1/14) and the difference was statistically significant (x2=8.955,P =0.040,OR =19.500,95％CI:2.787 to 136.461).However,in Han patients,there were no significant differences of HLA-DRB1 alleles frequencies among ANCA positive patients,ANCA negative patients and healthy controls (all P＞0.05),and the results of stratified analysis were same.Conclusions In Uygur UC patients of Xinjiang region,HLA-DRB1 * 13 may correlated with ANCA and with ANCA of pancolitis type UC patients.There is no such correlation in Han patients of Xinjiang region.

Objective: To explore health resource allocation and optimization and evaluate the clinical departments efficiency in hospital. Methods: Taking a three level of first-class hospital in Beijing for example, the method of data envelopment analysis (DEA) was used for building a DEA model of clinical departments efficiency in hospital. Results: Based on the results of the DEA model, we drawn the technical efficiency and scale efficiency of the target clinical departments, obtained input redundancy rates and output deficiency rates of the non-effective decision-making units. Conclusion:By DEA evaluation results, the input redundancy and output deficiency of the target clinical departments are found. From the perspective of optimizing hospital resource allocation, measures to improve the hospital operational performance are proposed. There is important significance to improve the comprehensive competitiveness of the hospital.

Clinical tutors' personality manifesting during the process of clinical practice and daily communication with medical interns has a series of influences on medical ethics formation of medical interns,including influences of direction,demonstration,contraction,and halo effect.Thus,clinical tutors should pay attention to cultivating a decent moral personality,and hospitals should value the proper combination of moral evaluation and supervision for medical staff in order to achieve the unity of heteronomous morality and self discipline,and effectively promote the formation of decent morality and personality of clinical tutors.

Objective The aim of this paper is to develop a holistic mathematical model to quantify the correlation between skin thermal sensation and noxious stimuli,since skin thermal pain is one of the most common problems in everyday life and the understanding of the underlying physical mechanisms is still not clear.Methods The model is developed by considering the biothermomechanical behaviour of skin tissue and by incorporating the current understanding of biophysical and neurophysiological mechanisms of pain sensation.Results The proposed model consisted of three interconnected sub-models: peripheral modulation of noxious stimuli,which converts the energy from a noxious thermal stimulus into electrical energy via nerve impulses;transmission,which transports these neural signals from the site of transduction in the skin to the spinal cord and brain;and modulation and perception in the spinal cord and brain.The model predictions agree well with existing experimental data.Conclusion With this model,a direct relationship has been built between the level of thermal pain sensation and the character of noxious stimuli.

Objective To investigate the factors related to negative conversion of HBsAg in patients with acute hepatitis B (AHB).Meth-ods A total of 106 AHB patients who were admitted to the Department of Infectious Diseases,Zhoukou Central Hospital from February 2007 to February 2013 were recruited.Liver function,five serological markers of HBV infection (HBsAg,HBeAg,anti-HBs,anti-HBe,and anti-HBc),and HBV-DNA were measured every three months.All patients were followed up for 12 months.The major HBV genotypes (A through D)were determined by type-specific primer nested PCR.Categorical data were expressed as rates and compared with χ2 test;continuous data were expressed as mean ±SD and analyzed by t-test.Results When just admitted to our hospital,compared with the pa-tients with negative conversion of HBsAg,AHB patients with HBsAg persisting for more than 6 or 12 months had a significantly lower peak level of alanine aminotransferase (ALT)(718 ±696 vs 1282 ±913 U/L,622 ±514 vs 1203 ±924 U/L,P<0.05)and a significantly high-er level of HBV-DNA (6.8 ±1.4 vs 5.2 ±1.5 log10 copies/ml,7.3 ±1.6 vs 5.4 ±1.5 log10 copies/ml,P<0.05).The HBsAg clear-ance rate in patients with HBV genotype A was significantly lower than that in patients with HBV genotype B or D (75.0% vs 89.5% or 100%,83.3% vs 97.4% or 100%,P<0.05).Conclusion The HBsAg clearance rate in AHB patients may be associated with HBV genotypes,peak level of ALT,and HBV-DNA.

Recently,there had been many researches about the effects of brain nat-riuretic peptide(BNP)and N-terminal pro-brain natriuretic peptide(NT-proBNP)on diagnosis and differential diagnosis of cadiovascular disease,risk classification,assessment of the treatment,prognosis and screening.Some results had been applied to clinical.This article reviews the progress of BNP and NT-proBNP on pe-rioperative monitoring for congenital heart defect.
