Objective To analyze the distribution and evolution of the risk factors for coronary heart disease (CHD) in middle-aging males, and provide the evidence for the prevention and treatment of male patients with CHD. Methods 1639 male people over 45 years old were enrolled in the study. They were divided into non- senile group (45-59 years old) and senile group (60-93 years old).The subjects over 60 years old were further divided into three groups:60-69 years old group, 70-79 years old group, 80-93 years old group. The interrelation between the risk factors of CHD and aging was analyzed. Results The prevalence rates of drinking, smoking, diastolic hypertension and low HDL-C in non-senile group were much higher than those in senile group (x2=28.80,18.35,15.72,17.84,P<0.01). In contrast, the prevalence rates of overweight, systolic hypertension, fasting hyperglycemia,postprandial hyperglycemia in senile group were significantly higher than those in non senile group. The prevalence rates of high triglyceride in non- senile group and senile group were 18.0% and 16.2% respectively(P>0.05). The prevalence rates of high cholesterol in non- senile group and senile group were 36.9% and 31.5% respectively(P>0.05). There was a significant decrease in the prevalence rates of overweight, postprandial hyperglycemia (P<0.05) and drinking,smoking, diastolic hypertension, high triglyeeride (P<0.01) in over 70-year+old males. And the prevalence rates of overweight, postprandial hyperglycemia, high triglyceride of over 80-year-old males were higher than those of over 70-year-old males (x2=10.05,4.16,5.97,P＜0.01). However,the prevalence rates of systolic hypertension of over 80-year-old males were lower than those of over 70-year-old males (X2=21.25,P＜0.01). There was no significant change in other risk factors of CHD at different ages of senile group. Conclusions For non-senile males, the important measures to treat the risk factors of CHD should include stopping smoking, restricting alcohol, eating low fat diet, changing bad life habits, controlling diastolic hypertension and modifying lipid. In contrast, for senile males, more attention should he paid to limiting total energy intake, increasing sports, losing weight, controlling systolic hypertension, hyperglycemia and modifying lipid.

Objective To investigate the association between the genetic polymorphisms of vitamin D receptor(VDR)and bone mineral density (BMD) in elderly male patients with chronic obstructive pulmonary diseases. Methods Pulmonary function, body mass index(BMI), serum calcium, serum phosphorus and bone glaprotein were determined respectively in COPD group and control group. In the two groups the VDR gene polymorphisms were analyzed by polymerase chain reaction and restriction fragment length polymorphism (PCR RFLP) and BMD were investigated by dual energy X ray bone mineral density. Results There were differences in BMD, BMI and bone glaprotein between the two groups. The BMI, bone glaprotein and BMD of femur neck in COPD group were(22 65?3 18)kg/m 2 ,(2 50?0 57) ?g/L and(0 75?0 13)g/cm 2 respectively, which were more decreased than those in control group: BMI (24 86?3 68)kg/m 2 , bone glaprotein (2 87?0 61) ?g/L and BMD of femur neck (0 86?0 12) g/cm 2 ( P

Objective To explore the quadriceps muscles function in patients with unilateral knee injury.Methods 23 unilateral knee injured patients with joint dysfuntion were assessed with isometric EMG activity of vastus lateralis (VL), vastus medialis obliques (VMO) and rectus femoris(RF) of both thighs during three 5-s maximal isometric voluntary contractions at a knee joint angle of 30° (0° - full knee extension), and the torque were recorded at same time. Results The average amplitude (AEMG), mean power frequency (MPF), and median frequency (MF) of VL, VMO and RF in affected knees were significantly lower than those in unaffected knees（P＜0.01）, as well as the torque（P＜0.01）. In the unaffected side, the AEMG, MPF of VL were higher than VMO and RF（P＜0.05）, and RF than VMO（P＜0.05）. In the affected side, the AEMG, MPF of RF are higher than VMO and VL（P＜0.05）, and VL than VMO（P＜0.05）. Conclusion sEMG can provide quantitative measurements of muscle function. The isometric strength and neuromuscular activation lever are lower in affected limb, RF may be affected less than VL and VMO in knee injured patients with knee dysfunction.

Abstract:Alcoholic liver disease (ALD) is one of the most common liver diseases in the world. Long-term alcoholism causes a series of pathological changes in the liver, which eventually leads to the occurrence of liver diseases with an increasing incidence. At present, significant progress has been made in the pathogenesis and pathological development of alcoholic liver disease, but the relevant mechanism of ALD has not been thoroughly studied. It is necessary to improve the existing animal model or establish a new, more comprehensive animal ALD model to simulate human ALD. Experimental animal models of ALD, especially rodents, are often used to simulate human ALD, and the ideal rodent ALD model can effectively simulate all aspects of alcohol in human liver. But so far, the commonly used animal models all have certain defects, and there is no complete animal model that can simulate human ALD. This paper reviewed the pathogenesis of ALD, related methods and influencing factors of ALD model, and provided a theoretical basis for relevant researchers to establish the ALD rodent model.

BACKGROUND: Vitamin D receptor (VDR) gene shows restriction fragment length polymorphism with incision enzyme Bsm Ⅰ ,Apa Ⅰ ,Taq Ⅰ ,which is related to bone mineral density (BMD).However, it is unclear that the relationship between VDR gene (Bsm Ⅰ ) polymorphisms and BMD,osteoporosis.OBJECTIVE: To analyze the distribution regularity of vitamin D receptor gene polymorphism related to BMD in postmenopausal women of Han,Uygur, Kazak and Mongoloid nationality in China. DESIGN: controlled observation.SETTING: Institute of Gerontology,General Hospital of Chinese PLA.PARTICIPANTS: Totally 179 women of Han,who were taking physical examination in General Hospital of Chinese PLA from January 2002 to December 2003, at the average age of (59±3) years,were selected. A total number of 122 women of Uygur with average age of 56.49 years; 63 women of Kazak with average age of (55±3) years; and 112 women of Mongoloid with average age of (57±3) years,who were all taking physical examination in department of geriatrics, Urumqi General Hospital of Lanzhou Military Area Command of Chinese PLA from January 2001 to December 2003.All of them were informed consent.METHODS: VDR genotypes(Bsm Ⅰ ) were defined with polymerase chain reaction-restriction fragment length polymorphism,so as to analyze distribution of Vitamin-D receptor gene (Bsm Ⅰ )polymorphisms of postmenopausal women in Han,Uygur, Kazak,Mongoloid nationality,and compared with the data of USA,Australia,France,Japan,Korea. Enumeration data were compared with Chi-square test.MAIN OUTCOME MEASURES: VDR (Bsm Ⅰ ) polymorphisms in healthy postmenopausal women from Han, Uygur, Kazak, Mongoloid populations in China, which were compared with the data of USA, Australia,France, Japan, Korea.RESULTS: For women of Han, Uygur, Kazak and Mongoloid nationality,the BB genotypes accounted for 0, 4.1%, 6.35% and 4.46%, the bb genotypes accounted for 90.5%, 69.67%, 38.1% and 50% respectively. There was a significant difference between women of Han, Uygur, Kazak, and Mongoloid nationality(P ＜ 0.01). There was insignificant difference in comparation of distribtuion of VDR genotype between Kazak nationality and the west races, but it was significantly different to that in Japan,Korea races.CONCLUSION:VDR genotype polymorphisms is characterized by obvious racial diversify in postmenopausal women of Han,Uygur, Kazak,Mongoloid populations in China;Distribution of VDR gene frequency of Kazak population is similar with the west race ,but is different to Japanese and Korea's race.

OBJECTIVETo explore the diagnostic value of the measurement of serum Golgi protein 73 (GP73) in the diagnosis of hepatocellular carcinoma (HCC).

METHODSEnzyme-linked immunosorbent assay (ELISA) was used to detect the serum GP73 in the 81 cases of HCC, 71 cases of chronic hepatitis or cirrhosis (CH/LC) and 65 cases of healthy blood donors, and to evaluate the sensitivity and specificity in the diagnosis of HCC through the ROC curves.

RESULTSThe average levels of serum GP73 in HCC, CH/LC and Normal groups were (152.67 +/- 33.59) ng/ml, (93.15 +/- 20.02) ng/ml and (58.95 +/- 17.29) ng/ml(o) After calculating through the ROC curves, 120 ng/ml was set as the optimal cut-off point, GP73 has a sensitivity of 77.80% and a specificity of 78.00%.

CONCLUSIONSGP73 as a serum marker in the diagnosis of HCC had a higher sensitivity than AFP, and the combined detection of GP73 and AFP could improve HCC diagnosis.
