ObjectiveTo investigate the age distribution of serum prostate specific antigen (PSA) and explore its correlation with fasting blood glucose(FBG)and lipid in the male elderly.MethodsThe levels of FBG,triglyceride (TG),low-density lipoprotein (LDL-C),high density lipoprotein (HDL-C) and PSA were reviewed in 2903 elderly men (aged ≥ 60 years) in our hospital.The subjects were classified into 6 groups by age,and PSA levels were compared among groups.The correlations of FBG,TG,LDL-C,HDL-C with PSA were analyzed using multiple linear regression analysis.Results The level of PSA had the trend to increase with age.Positive association of TG,LDL with serum PSA level,but negative correlation between HDL and serum PSA level were noted in the group aged 60-64 years (r=0.10,0.15,0.12,P＜0.05).In the group aged 66-69 years,there was negative relationship between FBG and serum PSA(r= 0.10,P＜0.05).No relationship could be found in other groups (P＞0.05).ConclusionsPSA level may increase with age,but without relation with FBG,TG,LDL-C and HDL-C.

Objective To evaluate the clinical efficacy of acupoint injection with BCG-polysaccharide nucleic acid (BCG-PSN) in treating bronchial asthma. Method Seventy-two patients with bronchial asthma were randomized into an acupoint injection group and a muscular injection group, 36 cases in each group. The acupoint injection group was intervened by acupoint injection with BCG-PSN to Zusanli (ST36) and Dingchuan (EX-B1) alternately, 1 mL for two points in total each time; the muscular injection group was intervened by muscular injection at the same dose and frequency, twice a week, for successive 3 months. The pulmonary function and asthma control test (ACT) were estimated before and after intervention and during March of the next year. Result After intervention, the FEV1 values were (80.97±2.31)% and (80.78±2.56)% respectively in the acupoint injection group and muscular injection group, and PEF values were (6.50±0.21)L/s and (6.48±0.25)L/s, and the between-group differences were statistically insignificant (P>0.05). The ACT score was (23.02±1.03) in the acupoint injection group, significantly better than (22.40±2.04) in the muscular injection group (P<0.05). The follow-up study showed that the ACT score in the acupoint injection group was superior to that in the muscular injection group (P<0.05). Conclusion Acupoint injection and muscular injection with BCG-PSN can equally improve the pulmonary function in bronchial asthma, while the acupoint injection can produce a more significant effect than muscular injection in improving ACT.

BACKGROUND: It is now know that the clinical presentations of subcortical arterioselerotic encephalopathy(SAE) could be mainly manifested by hypertension,stroke and chronic developed dementia,but there are very a few explorations on its definite pathogenesis and earlier assessment.OBJECTIVE: To investigate the correlation of CT classification of SAE with intellectual and neuropsycholohical disturbance,so as to explore the significance of CT classification of SAE to the assessment of SAE.DESIGN: Clinical case analysis based on patients.SETTING: A department of internal medicine in a military general hospital of Chinese PLA.PARTICIPANTS: From January 1999 to December 2002,totally 68 elders Guangzhou Military Area Command of Chinese PLA,included 65 males and 3 females,aged from 64 to 93 years old with the average age of(75. 8 ± 8. 1 )years old took part in the study.METHODS: Low-density focus around ventricle were observed with skull CT scanning and classified according to GOTO classification. Meanwhile the intellectual test and neuropsycholohical test were carried out,and the correlative analysis was conducted.MAIN OUTCOME MEASURES: Intellectual test,neuropsycholohical test,skull CT scanning,and analysis of correlation of CT classification with scores of intellectual test and neuropsycholohical test.RESULTS: Of 68 patients,91% (62/68) was proved to have different degree intellectual obstacle,100% was found to be vascular dementia; and low-density focus around ventricle were proved to be existed in all patients with skull CT scanning,GOTO classification indicated that type Ⅰ was found in 22 patients,type Ⅱ in 32 patients and type Ⅲ in 14 patients; skull CT classification was negatively correlated with the scores of intellectual test and positively correlated with scores of neuropsychiological test,with the correlative coefficient of -0. 83 and 0.75 respectively( P ＜ 0.01 ).CONCLUSION: GOTO classification of skull CT of SAE is related to intellectual obstacle and neuropsychiological disturbance in elder SAE.
