Objective To study the correlation between cystatin C and degree of renal function damage in patients with liver cirrhosis .Methods 160 cases patients of liver cirrhosis combined with renal damage were selected as the observation group and 45 cases patients of normal renal function as the control group .Then renal function inde-xes and cystatin C levels were observed.Results Compared with control group,Scr[(62.31 ±8.85)μmol/L, (63.58 ±8.01)μmol/L],Urea[(4.66 ±0.77)μmol/L,(4.71 ±0.82)μmol/L] level of renal functionⅠ,Ⅱsub-groups in the observation group had no significant differences .Cys C level was significantly lower than that of the con-trol group and showed renal function Ⅰsubgroup[(1.03 ±0.21)mg/L]

Objective To explore the correlation of ABO blood group and serum cystatin C level and decompensated hepatitis B cirrhosis.Methods Retrospectively analysed the clinical data of 472 patients with decompensated hepatitis B cirrhosis,and compared with 681 healthy control volunteers.All the informations such as gender,age,family history of liver disease,hepatitis B virus infection,hepatic function classification,complications of portal hypertension and the distribution of ABO blood group were observed.Results The highest incidence of decompensated hepatitis B cirrhosis was found in A blood group.There was no significant difference in the distribution of ABO blood group for patients with different age (P ＞ 0.05).Significant correlations were observed between AB blood group and family history of hepatitis B patients,expansion of the portal veines ＞ 1.5 cm,esophageal varices,cirrhosis complications,hepatic function classification (P ＜ 0.01).C ystatin C expression was increased with hepatic function classification (P ＜ 0.05).Conclusions The risk of liver cirrhosis is increased in patients with A blood group.Compare with other blood group,patients with AB blood group has a serious progression.The level of nitrogen,creatinine,cystatin C in decompensated cirrhosis are significantly higher than healthy controls.The level of cystatin C expression is increased with hepatic function classification.Cystatin C may be a potential marker in the classification of hepatic function.

Objective To evaluate the etiology and clinical features of jejunoileum bleeding.Methods Seventy-two patients admitted in 7 hospitals of Shangdong province for jejunoileum bleeding from January 1998 to December 2008 were enrolled in the study. There were 46 males and 26 females with mean age of 47 years (ranged 13-85 years). The jejunoileum bleeding was confirmed by means of endoscopy, images or surgery. The causes, diagnostic methods and major clinical manifestations were retrospectively analyzed. Results The most frequent cause of jejunoileum bleeding was tumor (42/72,58.3 %), followed by enteritis (9/72, 12.5 %), diverticulum ( 7/72, 9. 7%), angiopathy (7/72,9.7%), Crohn's disease (3/72,4.2%). Differences were significant in constituent ratio of cause of jejunoileum hemorrhage between male and female and between jejunum and ileum (P＜0.05).Hematochezia or hematochezia with abdominal pain was the first presentation. The jejunoileum bleeding in 54. 2% patients was diagnosed by laparotomy, 23. 6% by capsule endoscopy, 9.7% by selective angiography, 6.9% by small bowel series and enteroclysis, 2.8% by colonoscopy and 2.8% by push enteroscopy. The complications of jejunoileum bleeding were anemia, intestinal obstruction,peritoneal metastasis, shock, ankylenteron and intestinal perforation. Conclusions Intestinal tumor is the most common cause in jejunoileum bleeding, especially in jejunum. Whereas the enteritis,diverticulum and angiopathy were often found in ileum. The capsule endoscopy and push enteroscopy are recommended in diagnosis of jejunoileum bleeding.
