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.

Study the serum level of HGF, Cys C and TGF-beta1 in type 2 diabetic nephropathy (DN), the infect of Pingshen decoction on those index. Selected 69 cases of 2 type DN and randomly divided into therapy group (36 cases) and control group (33 cases). The therapy group were treated with Pingshen decoction 1 dose/d, bid po. The control group were treated with NephritisShu tablet, 6 tablet, tid po. 8 weeks was a course. Before and after treatment, we examine the serum level of HGF, Cys C and TGF-beta1 by ELISA and immunonephelometry, and compare with 30 cases of healthy control group. The study demonstrates that before treatment, the serum level of HGF in both groups were significantly lower than healthy control group (P < 0.01), but Cys C, TGF-beta1 were significantly higher (P < 0.01). After treatment, the serum level of HGF of both groups were increased. The serum level of HGF of therapy group were significantly higher than of control group (P < 0.01), but the serum level of Cys C and TGF-beta1 were significantly lower than control group (P < 0.01). The serum level of HGF was correlated negatively with Cys C,TGF-beta1. In control group, the UAER, urine beta2-MG and quantity of 24-hour urine protein were significantly decreased after treatment (P < 0.01). The index of urine of therapy group were significantly lower than control group (P < 0.01). Results indicate that test of serum level of HGF and Cys C,TGF-beta1 of diabetic nephropathy have important clinical significance. Pingshen decoction can effectively intervene in the serum level of HGF and Cys C, TGF-beta1 and index of urine.

OBJECTIVETo study the effects of specific immunotherapy with standardized house dust mite extract on the lung function and immunologic markers in children with asthma.

METHODSThirty-two children with mild to moderate asthma who were allergic to house dust mite were assigned to two groups: an immunotherapy group that received subcutaneous specific immunotherapy with standardized house dust mite extract beside glucocorticoids treatment (n=15) and a control group that received glucocorticoids treatment alone (n=17). Lung function was determined before treatment and 3, 6, 12, 18 and 24 months after treatment. The frequency of asthma attacks was observed before treatment and 12 and 24 months after treatment. Serum immunological markers, including total IgE, specific IgE and specific IgG4 against house dust mite (Dermatophagoides pteronyssinus, Der P), ECP, IL-10, IL-4, and IFN-γ, were measured before treatment and 12 and 24 months after treatment.

RESULTSThe parameters of lung function were kept at the normal level or near normal level after treatment in the immunotherapy group. Compared with before treatment, the percentage of patients without asthma attacks increased significantly after treatment in the immunotherapy group (P<0.05) and increased more significantly with a prolonged treatment time (P<0.05). The level of serum sIgG4 against Der P increased significantly throughout the period of the immunotherapy treatment compared with before treatment (P<0.01). There were no significant differences in the levels of serum total IgE, sIgE against Der P, ECP, IL-10, IL-4 and IFN-γ before and after treatment in the immunotherapy group. There were no significant differences in all the parameters measured before and after treatment in the control group.

CONCLUSIONSSubcutaneous specific immunotherapy with standardized house dust mite extract for two years decreases the frequency of asthma attacks and the lung functions are kept in a normal level in children with asthma. The role of the specific immunotherapy may attribute to the increased level of serum sIgG4 against Der P.

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.
