Objective To investigate the influence of age on liver histopathological feature of patients infected with chronic hepatitis B. Methods Liver biopsies were performed on 114 patients with chronic hepatitis B. The biochemical tests were measured by routine automated techniques. Serum hepatitis markers including HBsAg, anti-HBs, HBeAg, anti-HBe, and anti-HBc were assayed by using a microparticle enzyme linked immunosorbent assay. HBV-DNA was measured with quantitative polymerase chain reaction assay. The grades of liver necrosis/inflammation and fibrosis were compared between four groups with different age: younger than 20years, 20 ～ 30, 31 ～40, and older than 40 years. Results All 114 patients had liver histological changes with different degree. 75.4 percent (89/114) of cases had 2/over 2 grades of liver necrosis/inflammation, and 47.4 percent (54/114) of cases had 2/over 2 stages of liver fibrosis.There was no significant relation between the level of ALT and age or between the level of ALT and the grades of liver necrosis/inflammation and fibrosis( P ＞0. 05 ). The significant difference in degrees of liver inflammation and fibrosis was found among three age groups ( x2 = 30. 86, P ＜ 0. 01; x2 = 21.17; P ＜0.05 ). The grades of 1 iver inflammation and fibrosis increased with the increased age of the patients. Conclusion These results suggested that age was an independent factor for the disease progression. It was very important to undertake liver biopsy for patients with CHB more than 30 years to reveal the liver histopathological characteristics and guide the treatment.

Objective To investigate the changes of clinical and laboratory manifestations of rheumatic fever (RF) in recent ten years by reviewing the medical data of 315 patients with RF. Methods Three hundred and fifteen in-patients and out-patients with RF during 1985-1995 (group A) and 1997-2007(group B) were selected. Their manifestations were compared. Results Male/female ratio was about 1:2. Carditis and polyarthritis were common manifestations. Compared with group A, the rate of low-grade fever and carditis increased and the rate of heart failure, positive rate of C reaction protein and antistreptolysin O decreased in group B. In group B, 61.4% patients fulfilled the updated Jones diagnostic criteria. 76.2% fulfilled the 2002-2003 WHO criteria. The sensitivity and specificity of peripheral blood lymphocyte procoagulant activity (PCA) for the diagnosis of rheumatic carditis was 79.1% and 71.4% respectively. That of the anti-streptococcal group A polysaccharide (ASP) antibodies was 70.3% and 70% respectively. Five to ten years follow-up clinical data were available for 35 cases since Dec. 1997. The recurrent rate of RF was 62.8%. Only 1/3 cases received regular secondary prevention. Recurrence rate of patients with regular secondary prevention was significantly lower than that of patients without regular secondary prevention. Conclusion Mild earditis has been increasing during last ten years. PCA and ASP are valuable tests for diagnosing rheumatic carditis. More emphasis should be paid to atypical cases, early diagnosis and regular secondary prevention in order to improve prognosis.

Objective To determine the urine parameters,body temperature and main organ coefficient of Fujian rabbits.Methods In this experiment,we selected twenty healthy Fujian rabbits with weight of about 2.5kg.Both male and female rabbits were ten.Before experiment,the rabbits drunk water freely.We collected fresh urine before breeding in the morning,and then determined the ten items urine parameters soon.Under the room temperature,we used electricity thermometer into the rabbits' rectum to determine the body temperature.Being fasting for 12h,the rabbits were anesthetized by 3% pentobarbital sodium,and then were put to death after bloodletting.The dissection took various internal organs immediately.The clean organs were weighed by electronic analytical balance.Results The results showed that the majority of the urine was yellow opacity,and the ten items urine parameters between male and female had no significant difference.The average body temperature of Fujian rabbits was 39.67℃ above other ones.There was no significant difference in main organ coefficient between male and female expect the lung and spleen.Conclusion In a word,it was objective to determine the body temperature,urine parameters,mainly organ coefficient of Fujian rabbits which were fed in conventional environment.It is valuable for the appliation of Fujian rabbits in life science sphere.

Objective To investigate the effects of chondroitin sulfate proteoglycans (CSPGs) degradation induced by chondroitinase ABC (ChABC) on the rat flash visual evoked potential (F-VEP) around the end of the critical period of visual development.Methods A total of 30 Long Evans rats were randomly divided into 3 groups according to their age of 14,21 and 35 d.Then in each group,5 animals served as CSPGs degradation model induced by ChABC microinjection into 5 sites of the rat cortex [750 nL (48 U/ml) for 1 site,for 2 times at a 3-day interval],and the other 5 rats served as normal control and received normal saline microinjection.Immunofluorescence microscopy and laser scanning confocal microscopy were used to determine the establishment of animal model.F-VEPs were evaluated in 7 d after first microinjection.Results In the normal rats,the latency of F-VEP main wave became shorter with the increase of their age,the number was [(63.5?10.1),(50.8?6.4),(44.9?6.3) ms,P
