Objective To investigate the changes of CRP in diagnosis of the acute exacerbation of COPD and its significance.Method CRP and WBC were measured both when the patients just before and after the treatment with effective antibiotics to compare their change.Results The positive rate of CRP is 85.40%.and the difference Was obvious(P＜0.01).At the same time,the CRP's difference between before and after the use of antibiotics was also obvious(P＜0.01).Conclusion CRP is a sensitive and specific index to the acute exacerbation of COPD,and is helpful to discover this acute disease early as well as a good guide to estimate the serious of pneumonia sand to respond the efficacy of antibiotics.

Objective To investigate the relationship between plasma homocysteine levels and lipids in aged patients with acute cerebral infarction(ACI).Methods Fourty-eight cases(observation group),who had been inpatients with cerebral infarction during May 2006 to May 2007,thirty healthy people(control group)contrasted and analyzed.Results The mean plasma homocysteine level and cholesterol(TC),triglycerides(TG),low density lipoprotein(LDL)of aged patients with acute cereral infarction were significantly,higher than those of the control group,but high density lipoprotein(HDL)was lower(P＜0.01).No significant correlation between Hcy level and TC,TG,HDL-C,LDL-C level in serum.Conclusion Plasma homocysteine lexrel and lipids all siginificantly increased in aged patients with acute cereral infarction,and homocysteinemia is not related with lipids,but is an independent risk factor for cerebral infarction.

Objective To observe the effects of Biejia Jian (BJ) in preventing rat hepatic fibrosis. Methods Rat models with hepatic fibrosis were established by abdominal subcutaneous injection of 45 %carbon tetrachloride (CCl4) and olive oil. Fifty Wistar rats were randomly divided into 4 groups: model group (treated with normal saline),small-dosage BJ group (6.25 g/kg BJ), moderate-dosage BJ group (12.5 g/kg BJ) and large-dosage BJ group (25.0 g/kg BJ). The treatment lasted 10 weeks. On the 11th week, rats eyes were removed to get blood sample. The biochemical parameters of blood were detected and HE staining was applied for the pathological examination of liver. Results BJ decreased the serum levels of ALT,AST,HA, LN and PC III in rats, no pseudo-lobules found in the BJ groups. Proliferation of fibrous tissue was mild and Limited and fatty degeneration of hepatocytes were slight in moderate-dosage and high-dosage BJ groups as compared with the small-dosage BJ group.Pathological changes in BJ groups were significantly improved (P

Objective This study was designed to determine the serum CA-Hb 3 level in human colorectal carcinoma and analyze its clinical significance.Methods The level of serum CA-Hb 3 was measured by ELISA in 72 patients with colorectal carcinoma and 36 normal persons as the control group.Results The level of serum CA-Hb 3 in colorectal carcinoma was significantly higher than that of normal control .The level of serum CA-Hb 3 was positively related with tumor size,clinical pathological staging.With progression of clinical pathological staging (Dukes'stage),the level of CA-Hb 3 increased significantly,but its relation to tumor size,age,and sex was not significant.Conclusion Serum CA-Hb 3 assay may be a potentially valuable marker in assessment of pathological staging and judgement of clinical prognosis of colorectal carcinoma.
