Objective To investigate the expression of matrix metalloproteinase-2 (MMP-2)in pancreatic carcinoma and the relationship between MMP-2 with tumour clinicopatholngical features. Methods The expression of MMP-2 was detected by S-P immunohistochemistry in 36 cases with pancreatic carcinoma and 14 normal pancreat-ic tissues. Results The positive expression rate of MMP-2 was 66.7% (24/36) in pancreatic carcinoma tissue and 14.3% (2/14) in normal pancreatic tissues (χ2 = 3. 587, P < 0.01 ) ;The expression rate of MMP-2 in pancreatic carcinoma tissue with positive-node was 86.7% ( 13/15 ) ,which was higher than that with negative-node,which was 52.4% ( 11/21 ) ( P < 0.05 ) ; As to TNM staging in pancreatic carcinoma, the expression rate of MMP-2 was 41.2% (7/17) with Ⅰ,Ⅱ staging and 89.5% (17/19) with Ⅲ,Ⅳ staging(χ2=9.418,P <0. 01 ) ;The expression rate of MMP-2 was 50.0% (5/10) ,66.7% (10/15) and 72.8% (8/11) in highly,moderately and poorly differentiated pancreatic carcinoma(P > 0.05 ). Conclusions The expression of MMP-2 is strengthened significantly in pancreatic carcinoma tissue and involved in turnout invasion and metastasis features; MMP-2 might be regarded as one more marker for the invasive properties of pancreatic carcinoma.

Objective To understand the situation of oxidative stress among diabetic nephropathy (DN) patients and observe the antioxidative effect of losartan at increasing dose in DN patients. Methods Thirty type 2 DN patients who neither smoked and nor took antioxidants were selected. The study began with an initial 4-6 weeks screening-treatment. Eligible patients then received losartan 50 mg/d daily for 8 weeks followed by losartan 100 mg/day daily for an additional 8 weeks. Blood glucose and blood pressure were closely monitored over the whole study period. All patients were followed up every other weeks, their 24-hour urine samples,fresh urine and venous blood sample were collected to measure urinary protein and creatinine excretion, urinary 8-OHdG, SOD, TAOC and MDA excretion , serum SOD, TAOC , MDA and other blood biochemistry parameters. Urinary 8-OHdG was determined by capillary electrophoresis and liquid phase chromatography. Results The total 24 hours urinary 8-OHdG excretion and the serum MDA concentration were higher than the normal values. The serum and urine SOD concentrations were lower than the normal values. There was an improvement in urinary 8-OHdG,serum and urine SOD, serum and urine MDA levels with losartan therapy. Compared with losartan 50 mg/d, the antioxidative effect of losartan 100 mg/d was more noticeable. Obvious decrease in 24-hour proteinuria on exposure to losartan was found, without severe adverse effect. Conclusions Oxidative stress damage is active in DN patients. Losartan has antioxidative effect on DN patients. Compared with losartan 50 mg/d, the antioxidative effect of losartan 100 mg/d is more marked, without increasing side effect. Losartan's antioxidative effect may be involved in its beneficial mechanisms on DN.

0. 05). Conclusions Panipenem and betamipron are effective and safe drugs in the treatment of serious in-hospital infection in elderly patients.

OBJECTIVE: To compare the acute toxicity of common injection and sustained-release preparation of norcantharidin for mice so as to identify the attenuation of the sustained-release preparation of norcantharidin. METHODS: The poloxamer 407 was used as a sustained-release vehicle for topical administration of norcantharidin, and the acute toxicity of mice treated with common injection and sustained-release preparation of norcantharidin was observed. The median lethal dose (LD(50)) was calculated by Bliss software. RESULTS: The symptoms of mice were similar between the two groups, but the appearance of symptoms in norcantharidin/poloxamer 407 group was 4 hours later than that in norcantharidin group. The LD(50) of norcantharidin administered through vein injection was 12.6 mg/kg. The LD(50) of norcantharidin/poloxamer 407 administered through intraperitoneal injection, intrahepatic injection and intramuscular injection were 19.9, 19.1 and 20.9 mg/kg, respectively, and the LD(50) of the common preparation were 13.0, 13.1 and 15.1 mg/kg, respectively. CONCLUSION: The norcantharidin/poloxamer 407 is less toxic than the equivalent dose of norcantharidin, mainly because norcantharidin/poloxamer 407 may release norcantharidin sustainedly, thus reducing norcantharidin concentration in blood.

Purpose:The value of color doppler ultrasonography( CDUS) in monitoring hemodynamic changes was investigated in patients with hyperdynamic circulatory state before and during 730 days after orthotopic liver transplantation.Materials and Methods:83 cases of orthotopic liver transplantation (OLT) were examined by CDUS to assess the hemodynamic changes of portal vein,hepatic artery,splenic artery and longitudinal diameter of the spleen ( LDS).Results:(1) Portal flow velocity ( PFV) was significantly lower in pre-OLT but higher than controls (P < 0.05 ) during 730 days after OLT.Resistance index of the hepatic artery ( HARI) in pre-OLT and within 7 days- after OLT was significantly higher (P<0.05).(2) Resistance index of splenic artery ( SARI) was also significantly higher in pre-OLT (P < 0.05 ).LDS was significantly higher after OLT than in both pre-OLT phase and controls(P<0.05).Conclusions: In early stage after OLT,HARI changed from high to low value and so did PFV,which kept the stability of hepatic blood flow.In late stage,high PFV and large spleen improved,but could not back to normal.

Objective To compare the rehabilitation effect of free rehabilitation, the needle therapy and the hand function recovery machine combined with free rehabilitation on movement function, the feeling function as well as the movement pattern of newly stroke patients with hemiplegia. Methods 49 newly stroke patients were divided into the free rehabilitation group, the acupuncture group and the hand function recovery machinegroup, each group received corresponding intervention. The movement function, the feeling function as well as the movement pattern were compared among the three groups using blind method. Results Brunnstrom evaluation for hands feeling-movement function, the Fugl- Meyer evaluation score showed obvious progress compared to before the treatment, score of fine hand - function assessment of Carrshepherd showed no change. Two weeks after treatment,Brunnstrom evaluation for hands feeling-movement function and the Fugl - Meyer evaluation score showed no difference between the free rehabilitation group and the acupuncture group, but the hand function recovery machine group showed better results than the other two groups. One months after treatment,Brunnstrom evaluation for hands feeling-movement function was different among these groups, but not the Fugl-Meyer evaluation score, the hand function recovery machine group showed better results than the other two groups, still score of fine hand-function assessment of Carrshepherd showed no change. Conclusions Acupuncture, free rehabilitation, hand function recov - ery machine all make progress in hand function recovery for newly stroke patients with hemiplegia, but hand function recovery machine combined with free rehabilitation proved to be the best method. Its effect for hand intricate function needs to be enhanced.

Objective To compare the effect of different partition of nucleic acid protein complex on the affinity of enriched library in systematic evolution of ligands by exponential enrichment (SELEX). Methods Two protocols were adopted to select the enriched library to transforming growth factor ? receptor Ⅱ(TGF ? RⅡ). Protocol 1: protein was absorbed on the surface of 96 well plate; then, selection was carried out; the binding nucleotide acids were eluted from the supporter directly. Protocol 2: selection was done in solution; nucleotide acid protein complex was captured in nitrocellulose membrane; the binding nucleotide acids were obtained from membrane. Filter biding assay and gel shift assay were performed to detect the affinity of the enriched ssDNA library from different protocols. Results After 4 rounds of selection, the affinity to TGF ? RⅡ was obviously improved in the enriched library from protocol 2 compared with the initial library, while no such improvement was found in the enriched library from protocol 1. Conclusion In the SELEX experiment, the way of selection in solution, then partition of the binding nucleotide acids in filter is easier to enrich the binding fragment from initial ssDNA random library, compared with the way of fixation of target protein to solid supporter, then selection between the solid phase and liquid phase and elution of the binding nucleotide acids from supporter.
