Objective　To study the clinical manifestation of small bowel tumors and the prognostic factors. Methods　Retrospective analysis of the clinical data were made on 42 cases of primary small bowel tumors (except periampullary tumors) admitted to our hospital from 1974 to 1999. Results　In this series, there were 6 cases of benign small bowel tumors, 5 of them were leiomyoma and 1 adenoma. Of the 36 cases of malignant 　tumors, there were malignant lyphoma in 17 cases (47.2%), adenocarcinoma in 11 (30.6%),　 leiomyosarcoma in 6(16.7%), carcinoid tumor in 1 (2.8%) and neurofibrosarcoma in 1 (2.8%). There was no characteristic clinical sign in small bowel tumors; endoscopy and barium series were the main diagnostic methods. About 50 per cent of patients with malignancy had metastasis, and only 18 cases (50%) received radical resection. Follow-up were available on 36 cases. The overall 5-year survival rate in the patients with malignant small bowel tumors was 47.3%. Multivariate analysis showed that metastasis and diameter of tumors were the main prognostic factors of the 5-year survival. Conclusions　Early diagnosis and early treatment play the key roles in improving the prognosis of malignant small bowel tumors. Radical resection should be taken if no metastasis is found.

0.05).② On diagnosing ACS,the area under ROC curve of sCD40L was 0.773,the sensitivity,specificity and validity are 82.8%,61.9% and 85.7%,respectively,which were all highest among so much indexes.Conclusion High serum sCD40L levels may suggest vulnerable plaque,and it's somewhat valuable in diagnosing ACS.

Objective To study the clinical role of the variation of serum matrix metalloproteinase-8 (MMP-8)concentration in patients with acute coronary syndrome (ACS). Methods ELISA method was adopted to detect serum MMP-8 concentration and to observe concentration's differences and features among 80 selected ACS cases (43 acute myocardial infarction and 37 unstable angina pectoris), 43 stable angina pectoris (SAP) cases and 37 control cases.And meanwhile the atherosclerosis risk factors of each case, such as age, sex, hypertension, body mass index, smoking,family history, diabetes, and hyperlipidemia were collected and analyzed as a whole. Results First, serum MMP-8 concentration reached the highest point in ACS, and there was significant difference between SAP and control groups (P<0.01). Second, sermn MMP-8 in AMI was much higher than that in UAP with significant difference (P<0.01). There was no difference between UAP and SAP groups (P>0.05). Third, Logistic regression analysis revealed that serum MMP-8 concentration might be the indicator of ACS (B=4.493, P=0.000), particularly, that of AMI (B=9.961,P=0.000). Fourth, linear correlation and linear regression analysis found that only neutrophil was likely to influence serum MMP-8 concentration (r=0.274, P=0.001). Fifth, in the diagnosis of ACS, the area under ROC curve of MMP-8 was 0.785, the sensitivity and specificity were 68.6% and 76.5%, respectively. Conclusion ① Serum MMP-8 concentration has close relationship with the occurrence of ACS, particularly with AMI;② Serum MMP-8 concentration may be one of the predicting indicators of ACS and particularly of AMI;③ Neutrophil may be correlated with serum MMP-8 concentration;④ MMP-8 is of somewhat valuable in diagnosing ACS.

Objectives:To study the value of fructose-1,6-diphosphate-supplemented parenteral nutrition in elder abdominal surgical patients.Methods:thirty-two patients were randomly allocated into study group and control group,receiving isocaloric(83.6 kJ/kg?d~(-1)) and isonitrogenous(0.2 g/kg?d~(-1)) PN from post-operation day 1 to post-operation day 6.The study group received 10g of FDP every day and did not receive Glycophos.Plasma albumin,pre-albumin and phosphate lever were measured and EKG was examined before surgery and days 1 and 7 after surgery.The level of 3-methylhistidine(3-MH) in urine was measured and nitrogen balances were calculated postoperatively on day 1,3,5 and 7.Results:The blood phosphate levels were normal in two groups before and after surgery.Compared with preoperation,plasma albumin and pre-albumin levels were both decreased in two groups and pre-albumin level was markedly decreased in the control group(P

Objective To explore the MRI features of pelvic endometriosis outside the ovary.Methods 13 patients with pelvic endometriosis outside the ovary were imaged.Their clinical and imaging data were reviewed retrospectively.All cases were con-firmed by pathology.An enhanced MR using T1 WI sequence both in sagittal and transverse position was performed after T2 WI fat-suppression sequence and T1 WI sequence.Our MRI study was focused on the distribution of lesions locating in the deep pelvic cavity and abdominal wall,and the features of MRI signals .Results 13 lesions were found,in which 4 lesions located in the rectouterine pouch of Douglas,2 cases the bladder wall,2 cases the unilateral cystic inlet of ureter,1 case the anal canal wall,and 4 cases the ab-dominal wall.10(10/13)lesions were shown as solid nodules while 3(3/13)lesions as cyst-solid ones.All lesions showed moderate-ly heterogeneous enhancement.Conclusion Pelvic endometriosis outside the ovary mainly shows solid or cyst-solid lesions that lo-cates in the urinary,uterus,rectal wall and spaces around them.MR images show a higher value for the detection of the lesions out-side the ovary.
