1.Apolipoprotein E genetic polymorphism and plasma lipids
Chinese Journal of Pathophysiology 1986;0(03):-
A rapid thin flat gel isoelectric focusing method followed by ultrasensitive silver staining was developed for the determination of apo E phenotypes. Using this method, apo E phenotypes and allele frequencies in 63 normal individuals, 70 patients with hyperlipidemia and 11 patients with familial hypereholesterolemia (FH) in Nanjing were examined. TC, TG, HDL-C, LDL-C, VLDL-C, VLDL-TG in these cases were also measured. The relative frequency of the ?4 allele is significantly lower while the relative frequency of the ?3 allele is higher in this group than in the Caucasian group. Plasma TG, VLDL-TG, VLDL-C and VLDL-C/VLDL-TG are higher in the apo E3/2 phenotype, and lower in the apo E4/3 phenotype, wherea splasma TC, LDL-C levels are lower in the apo-E3/2 and higher in the apo E4/3 phenotype. It implies that the ?2 allele has the action of increasing TG-rich lipoprotein particles and reducing ch-rich lipoproteins in plasma, while the ?4 allele has an effect opposite to that of the ?2 allele. The highest prevalence of the ?4 allele was associated with type Ⅱb hyperlipoproteinemia (HLP), while that of the ?2 allele was associated with type Ⅲ-HLP. The frequency of ?2, ?4 are higher in FH patients as compared with normal subjects.

Objective To investigate the protective effects of FUZHENGJIEDU,a kind of Chinese herb on rats exposed to radon and it's daughter.Methods Twelve male SD rats were exposed with concentration of 40 000 Bq/m3 radon and the exposed dose was 120 work level month (120 WLM),and then all the rats were randomly divided into 2 groups.One group was 120 WLM group (positive control,n=6 ),the other group was FUZHENGJIEDU treatment group (120 WLM exposed rats were given FUZHENGJIEDU 5.0 g every day,n =6),meanwhile 6 rats which lived in the normal environment ( the concentration of radon and it's daughter was lower than 50 Bq/m3 ) as control group.The levels of tumor markers induding carcinoembryonic antigen ( CEA),neuron-specific enolase (NSE),CYFRA21-1 and p53 antibody were tested by ELISA.The rate of p16 gene methylation was measured by methylation-specific PCR (MSP).Results The levels of CEA and NSE in 120 WLM group were (396.62 ± 148.74) and (9.09 ±0.90) μg/L,respectively,significantly higher than those of control group (t =2.583,2.463,P < 0.05).The levels of CEA and NSE in treatment group were (70.89 ±44.71) and (4.31 ±1.37) μg/L,respectively,remarkably lower than those of 120 WLM group (t =2.921,2.526,P <0.05 ).The concentrations of CYFRA21-1 and p53 antibody were not significantly different among the three groups (t =1.713,1.963,P > 0.05 ).The rate of p16 gene methylation in BALF cells in 120 WLM group was 16.67%,but in control group and treatment group did not arise p16 gene methylation in BALF cells.Conclusions FUZHENGJIDU would decrease the levels of CEA and NSE and the rate of p16 gene methylation,and could exert it's protective effect on rats exposed to high concentration of radon.

Objective To investigate the related factors of nursing dependence in bladder cancer patients with urinary diversion and abdominal wall stoma.Methods The clinical data of 120 patients with bladder cancer undergoing abdominal ostomy with urinary diversion in the hospital from June 2020 to June 2022 were retrospectively analyzed.The self-esteem scale,the civilian version of the Post-traumatic Stress Disorder Scale,the Personal Sense of Control Scale,and the Nursing Care Dependence Scale were used to evaluate the self-esteem level,post-traumatic stress disorder level,personal sense of control level and nursing dependence degree of patients,and carry out univariate and multivariate regression analysis on the influencing factors of nursing dependence in patients with bladder cancer urinary diversion and abdominal stoma.Results The total score of nursing dependence in 120 bladder cancer patients with urinary diversion and abdominal wall stoma was 56.95±7.94.The lowest score was activity,followed by excretion and cleanliness.Univariate analysis showed that there were statistically significant differences in the nursing dependence scores of patients with different age,marital status,educational level,work status,per capita monthly income,and comorbidities(P<0.05);the patients'self-esteem,the civilian version of the Traumatic Stress Disorder Scale,and the Personal Sense of Control Scale scores were 25.08±2.59,46.04±5.72,24.18±2.95,respectively;after multi-factor a-nalysis,it can be seen that age,education level,comorbidities,self-esteem level,post-traumatic stress obstacles and personal control finally entered the regression equation as factors influencing dependence on care for pa-tients with urinary diversion abdominal wall stoma for bladder cancer(P<0.05).Conclusion Bladder cancer patients with urinary diversion abdominal wall stoma have the highest degree of dependence on nursing care for mobility,excretion and cleaning.Age,education level,complications,self-esteem,post-traumatic stress dis-order,and personal sense of control are related factors that affect the degree of dependence on nursing care.

Objective:
To investigate the prognostic impact of alterations of epidermal growth factor receptor(EGFR) and MGMT in glioblastoma.
Methods:
The retrospective study included 161 supratentorial glioblastomas diagnosed in the Department of Pathology, Xuanwu Hospital, Capital Medical University from 2009 to 2015. EGFR and EGFRvⅢ protein expression was detected by immunohistochemistry; EGFR amplification was detected by fluorescence in situ hybridization; MGMT promoter methylation was detected by pyrosequencing. The change of molecular genetics EGFR and MGMT and outcome were assessed statistically.
Results:
There were 161 patients, including 85 (52.8%) males and 76 (47.2%) females. The mean age was 53 years, and the median overall survival was 13 months. The integrated classification of glioblastoma included 16 IDH-mutant, 134 wild type, and 11 NOS. The rate of overexpression of EGFR protein was 32.9%(53/161), and that of EGFR amplification was 37.5%(18/48). There was high concordance between immunohistochemistry and FISH(85.4%, Kappa=0.475,
