Methods EPS was obtained from 75 out patients with chronic prostatitis,pH and WBC per high power microscopic field being studied.Transabdominal prostatic ultrasonography was performed. Results Mean pH of the EPS was 6.9?0.4.pH of the EPS and the frequency of ultrasound abnomalities were significanly correlated to the leukocyte count in EPS.There was no correlation between age of symptom duration and the pH of EPS, frequency of ultrasound abnormalities or white blood cell counts in EPS. Conclusions In chronic prostatitis,the leukocyte count in EPS was positively correlated with the ultrasound abnomalities and the pH elevation of EPS.There was no correlation between age or symptom duration and pH of the EPS,frequency of ultrasound abnormalities or leukocyte count in the EPS.

Objective To study the influence of finasteride on the expression of hypoxia-inducible factor 1 α(HIF-1 α) and vascular endothelial growth factor (VEGF) with prostate cancer (Pca).Methods The patients diagnosed of Pca were selected,and which treated with finasteride for up to six months were finasteride group and untreated with finasteride were control group.The expression of HIF-1 α,VEGF and microvessel density(MVD) was examined.Results The positive expression of HIF-1α,VEGF and MVD in the finasteride group were 55.0％,57.5％,(56.9 ± 13.8),respectively,and were lower than those of the control group [87.5 ％,97.5 ％,(64.2 ± 13.3)] (x2 =10.313,18.122,all P ＜ 0.01 ; t =2.391,P ＜ 0.05).In the pathological grade,advanced grade of the finasteride group was in 15 cases(37.5％),and 10 cases(25.0％) was in the control group,and the difference was statistically significant between the two groups(x2 =1.455,P ＞ 0.05).Conclusion Long-term treatment with finasteride can reduce expression of HIF-1α and VEGF with Pca,thus inhibit angiogenesis and tumor growth and metastasis.

A high sensitive and selective imprinted electrochemical sensor based on cobalt nanoparticles/gra-phene modified carbon electrode was prepared by electropolymerization technqiue with p-tert-octylphenol as the template and pyrrole as the functional monomer. The electrochemical behaviors of the imprinted sensor were evaluated with cyclic voltammetry and differential pulse voltammetry. The response currents of the imprinted electrochemical sensor exhibited a linear relationship toward the negative logarithm of p-tert-octylphenol concentrations ranged from 1. 0í10-13 mol/L to 1. 0í10-7 mol/L (R2=0. 994) with the detection limit of 3 . 7í10-14 mol/L ( S/N=3 ) . The imprinted electrochemical sensor was respectively applied to the determina-tion of p-tert-octylphenol in rain water, lake water and drink with the recoveries of 92. 4%-102. 0%.

To investigate the protective effects of OLA-PENa on experimental hepatic injury in rats and compare it with OLA in the dose-response relationships. METHODS: Biochemical indexes and histopathological examination of hepatic injury in rats caused by toxicant chemicals ［D-galactosamine (D-Galn) and CCl4］ were determined. RESULTS: OLA-PENa obviously inhibited the rising of serum alanine transaminase (ALT) caused by D-Galn and CCl4 and dramatically decreased liver fat storage as well in a dose-dependent manner. Histopathological examination showed that OLA-PENa can evidently alleviate the condition of the degeneration of hepatic cells and that of necrosis. CONCLUSION: The protective effects of OLA-PENa on experimental liver injury in rats, all the mentioned effects, are more powerful than those of OLA with the same dosage.

Purpose:To analyze the clinical manifestations, so the diagnosis of hepatoid adenocarcinoma of the stomach (HAS) may be made and treatment instituted as early as possible. Methods:A total of 65 cases of HAS reported in the literature in recent ten years reviewed.Results:①Clinical symptoms and signs: The incidence of HAS in male was higher than that in female (6.2:1).Upper abdominal discomfort and physical signs of mass bclow the sternum were most commonly seen.②Diagnosis: The serum content of AFP were discombfort high level with a positive rate of 66.7%(22/33). The positive rate of AFP expression with immunohistochemical method was 94.5%(52/55).The percentage of liver metastasis detected by US B or CT was 20.5%(9/44) preoperation, and mostly seen at the gastric sinus was ahout 63.3%(19/30). The final diagnosis of HAS depends on gastrocopy and pathology. ③Treatment and Prognosis: The possibility of radical operation(D 2 ) is only 17.9%(5/28). The death ratio within one year was 56.3%(18/32).Conclusions: HAS is primarily a gastric carcinoma. The serum AFP levels are help fulin the diagnosis and differential diagnosis of HAS. The diagnostic evidence of HAS is dependant on its specific forms. The prognosis is often poor because of frequent liver metastasis.
