Objective To evaluate whether high sensitivity C-reactive protein is associated with microvascular complications in patients with type 2 diabetes mellitus.Methods A total of 321 patients with type 2 diabetes mellitus were recruited.According to the results of 8 h urine albumin excretion rate,ophthalmoscope examination and nerve conduction velocity test,nephropathy,retinopathy and neuropathy were defined respectively.To evaluate differences of the serum hsCRP levels of those with and without nephropathy,retinopathy and neuropathy.Results Only diabetic nephropathy correlated with the serum hsCRP level.With increment of urine albumin excretion rate,hsCRP level was increased.Pearson correlation analysis indicated that hsCRP correlated positively with urine albumin excretion rate(r=0.448,P=0.002),triglyceride(r=0.385,P=0.008),and body mass index(r=0.261,P=0.004).Stepwise linear regression showed that hsCRP and UAER,TG and BMI existed linear correlation.Conclusion hsCRP is associated with diabetic nephropathy and its level is correlated with the degree of diabetic nephropathy.

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 effectiveness of arthroscopically assisted percutaneous reduction and internal fixation with eannulated screws.Methods The fracture was reduced by closed manipulation or percutaneous leverage force by using the Kirschner wire.Then the patella was temporarily fixed by using a large size towel clamp or Kirschner wires.Under the guidance of knee arthroscopy,a micro-incision was made at the size of cannulated screw placement,the pilot holes were drilled at a proper depth,and the thread was configured.Two titanium screws were inserted parallelly.Results Following-up chekups for 4～24 months in 18 cases showed a satisfactory recovery of knee functions.According to the Bostman' standard,excellent effects were obtained in 16 cases and good effects in 2 cases.Conclusion Treatment of patellar fractures by percutaneous cannulated screw fixation under arrhroscope of- fered advantages of minimal invasion,accurate reduction,reliable fixation,and excellent recovery of joint functions.

Aim To determine the possibilities and mechanisms of EGFR, a receptor protein tyrosine kinase associated with many important cellular processes re-sponsible for cardiovascular remodeling in renovascular hypertensive rats. Methods 2K1C hypertensive rats were used in the present study. Blood pressure was measured with the tail-cuff method. LVMI and his-topathological changes in the cardiovascular system were analysed. EGFR expressions of aorta and myocar-dium as well as phosphorylation levels of ERK in hy-pertensive rats were detected by immunohistochemistry and Western blot analysis, respectively. Results Sys-tolic blood pressure was markedly increased 2 weeks after 2K1C surgery. Cardiovascular remodeling induced by hypertension was confirmed by elevated LVMI, pro-liferation of collagen fibers in myocardial interstitium, histopathological changes in cardiovascular system and increased IMT of thoracic aorta 6 weeks after 2 K1 C surgery. Compared with sham rats, EGFR expression in the ventricular myocardium of 2 K1 C rats was signifi-cantly increased at 6 weeks ( P<0. 05 ) , and the EG-FR/GAPDH ratio was higher in 2 K1 C rats with higher systolic blood pressure ( P < 0. 05 ) . Phosphorylation level of ERK 1/2 was upregulated correspondingly in 2 K1 C rats ( P <0. 01 ) . Increased EGFR expression was also found in aortas of 2K1C rats, particularly in tunica intima and media. Conclusion EGFR and its down-stream kinases ERK 1/2 are involved in cardio-vascular remodeling in association with the severity of hypertension in renovascular hypertensive rats.
