Objective To study the expression of basic fibroblast growth factor (bFGF),thrombospondin-1 (TSP-1) and the mi- crovessel density (MVD) and their relationship in esophageal squamous cell carcinoma.Methods Forty-six specimens of resected, paraffin embedded esophageal specious of squamous cell carcinoma were examined by immunohistochemical technique for the MVD and expression of bFGF and TSP-1.Results Of the 46 patients,the positive rate of bFGF and TSP-1 were 60.9% (28/46) and 37.0% (17/46),respectively.The mean value of MVD was (56.59?28.97)/mm~2.The depth of invasion had a significantly positive corre- lation with positive expression of bFGF and TSP-1.TNM stage had a significantly positive correlation with positive expression of TSP- 1.The value of MVD was closely associated with histological grade,lymph node metastasis and the expression of bFGF.Conclusion bFGF,TSP-1 and tumor microvessel play important roles in development and progression of esophageal squamous cell carcinoma. bFGF is a important regulator of tumor angiogenesis.

Objective To study the therapeutic effects of human umbilical cord mesenchymal stem cells (hUCMSCs) on acute liver failure ( ALF) induced by D-galactosamine (D-gal) and lipopolysaccharide (LPS) in rats. Methods The ALF model was obtained through intraperitoneal injection of D-gal(300 mg/kg)and LPS (20μg/kg)in Wister rats. The hUCMSCs were transplanted after intoxication. All rats were divided into four groups, and each group received either hUCMSCs or 0.9% NaCl solution through intraperitoneal or tail-intravenous injection. To evaluate the liver function of each group, the levels of alanine aminotransferase (ALT), total bilirubin (TBil) and serum albumin (Alb) were measured on the day of hUCMSCs transplantation and the following 1, 2, 3, 5 and 7 days. All rats were then sacrificed to examine the liver histology at day 7. Analyses were done by using Fisher's exact test, unpaired t test and Mann-Whitney U test. Results There were no significant differences of survival rates among four groups (Fisher's exact test, both P = 1. 00). The levels of ALT, TBil and Alb in group receiving hUCMSCs intraperitoneally were (804. 9 ± 88. 0) U/L,(17. 4±2. 7) μmol/L and (20. 9±0. 8) g/L, respectively after 2 days of injection, whereas in the corresponding control group, those were (1294. 3± 171. 4) U/L, (32. 3±5. 5) μmol/L and (16. 1±0. 9) g/L, respectively, which indicated that hUCMSCs transplantation significantly improved the liver function (t = 2. 640, P =0.020;t=2.529, P = 0. 025;t= - 3. 833, P = 0. 002). Both of hUCMSCs-transplanted groups showed no significant differences. Liver histological data showed that transplantation of hUSMSCs through either intraperitoneal or tail-intravenous injection alleviated liver damage (U=4. 500, P = 0. 005;U=4. 500, P = 0. 008) and the mitotic index also increased in hUCMSCs-transplanted groups (U=4. 000, P = 0. 005; U=5. 500, P = 0. 013). Conclusions The levels of ALT, TBil and Alb can rapidly normalize in ALF rats after injected with hUCMSCs either intraperitoneally or tail-intravenously. hUCMSCs application raises the mitotic index, enhances hepatocellular regeneration and improves histological status.

OBJECTIVETo study the factors influencing the activity of fibrinolytic enzymes from earthworm and to obtain the better way to extract fibrinolytic enzymes as well as keep its optimum activity.

METHOD75% alcohol, 0.9% NaCl and 10% saccharose was used to extract the crude fibrinolytic enzymes from earthworm, the method of urokinase gelose-fibrin plate was used to measure the activity of fibrinolytic enzymes from earthworm. and the method of 3,3'-diaminobezidine tetrahydrochloride colorimetry to was used measure the content of selenium. The method use ts of measuring the content of arsenic was silver diethyldithiocarbamate colorimetry.

RESULTThe fibrinolytin of earthworms reared with cattle soils had higher activity than that reared with garbage. The arsenic in the earthworm's body could improve the activity of earthworm's fibrinolytin. However, the selenium had litter influence on it. Among the three methods of extraction, the 75% alcohol one was the most efficient, the 0.9% NaCl was next, and the 10% saccharose was the lowest. The influence of dialysis on the activity of fibrinolytin was less than that of ultrafiltration, when the earthworm's fibrinolytin enzyme was further sublimated.

CONCLUSIONThe activity of the earthworm's fibrinolytin will be increased earthworm is reared with the fitting baits and when appropriate methods, of extraction and purification are used.

Objective To evaluate the early appearance of SARS on chest CT scan and its role in the early diagnosis Methods Forty cases of SARS in keeping with the criteria of the Ministry of Health had chest CT scans within 7 days of onset of symptoms, and CR chest X-ray films were available as well These chest X-rays and CT images were retrospectively reviewed to determine if there were any abnormalities on the images The lesions on the chest CT images were then further analyzed in terms of the number, location, size, and density Results Positive abnormalities on chest CT scans were revealed in all 40 SARS cases Positive findings on CR chest films were showed in only 25 cases, equivocal in 6, and normal in 9 cases The main abnormalities seen on CT and X-rays were pulmonary infiltrations varied markedly in severity 70% cases had 1 or 2 lesions on chest CT scan, 30% cases had 3 or more lesions The lesions seen on chest CT scan tended to be ground-glass opacification, sometimes with consolidation which was very faint and inhomogeneous, easily missed on chest X-rays Typically the lesions were located in the periphery of the lung, or both central and peripheral lung, but very rare in a pure central location They were commonly in the shape of patch or ball Conclusions Chest CT scan is much more sensitive in detecting the lesions of the lung in SARS The early appearance of SARS on chest CT scan is characteristic but non-specific, indicating that chest CT scan plays a very important role in the early diagnosis and differential diagnosis of SARS

Objective To analyze the imaging findings of osteosarcomatosis, and to explore the value of imaging in the diagnosis of osteosarcomatosis.Methods Clinical data and imaging findings in 15 cases of osteosarcomatosis were reviewed.All of them had conventional X-ray films, 13 cases had CT scanning, 11 cases had ECT scanning, 5 cases had MR scanning, and 4 cases with DSA.Results Eight primary lesions were located in the distal femur, 5 in the proximal tibia, 1 in humerus, and 1 in clavicle.Secondary lesions were scattered in proximal tibia in 8, distal femur in 6, spine in 6, pelvis in 2, and other sites.The primary lesion showed typical X-ray finding of osteosarcoma, but lesions at other position showed mainly high density of osteogenesis in all 15 cases.In 13 cases, CT played an important role in defining the extent of the tumor and soft tissue masses.CT scanning was sensitive in detecting osteosclerotic lesions in the bone marrow.In 5 cases, MRI was useful in delineating the extent of tumor and soft tissues mass, as well as the extent of tumor in bone marrow.ECT had the capacity of showing the radionuclide concentration of tumor focus in the whole body in a single scan in 11 patients.Conclusion Osteosarcomatosis has multiple lesions all over the body.Imaging modalities including X-ray plain film, CT, MRI, and ECT are all important in finding the lesions and in diagnosing osteosarcomatosis.

Objective To compare complications of ureteroneocystostomy and end-to-end ureteroureterostomy after kidney transplantation. Methods Eighty allograft renal transplantation patients between January 2005 and October 2008 were divided into two groups according to urinary tract reconstruction approach: ureteroneocystostomy group (40 cases) and ureteroureterostomy group (40 cases). Complications including leakage of urine,vesicoureteral reflux,obstruction of ureter and urinary tract infection were recorded.Results In ureteroneocystostomy group and ureteroureterostomy group,the patients were followed up for 13 - 46 (24.5 ± 8.9), 13 - 46 (26.0 ± 7.2) months postoperatively, urinary complications were recorded for 10 eases (25.0%, 10/40) and 4 cases (10.0%, 4/40)(P > 0.05), incidence of leakage of urine were 2.5%(1/40)and 5.0%(2/40) (P > 0.05), vesicoureteral reflux were 10.0% (4/40) and 0 (P ＜ 0.05), obstruction of ureter were 0 and 5.0% (2/40) (P > 0.05), and urinary tract infection were 12.5% (5/40) and 0 (P < 0.05).Conclusions Compared with ureteroneoc ystostomy, ureteroureterostomy can reduce the incidence of vesicoureteral reflux and urinary tract infection,it can be regarded as the first choice for urinary tract reconstruction after kidney transplant recipients.
