Purpose To analyze the 64-row spiral CT manifestations and evaluate the diagnostic value in early primary ureteral carcinoma.Materials and Methods Fifteen cases of early primary ureteral carcinoma proved by surgery and pathology were reviewd.Unenhanced scan,enhanced scan in arterial phase,parenchymal phase,delayed phase and CPR construction were performed in all patients.MIP were performed in 10 cases.Results ① the localization of lesions:7cases were located at the right ureter and 8 cases at the left.2 cases were located at the upper portion of the ureter,6 at mid portion,and 7 at lower portion;② CT manifestations:8 cases showed irregular thickened wall and central lumen stenosis,4 cases eccentric soft tissue mass in lumen and crescent or linear vestigial lumen,3 cases soft tissue density and obsolescent lumen;③the enhanced features:the tumor was demonstrated apparent and uniform enhancement in 13 cases,inhomogeneous enhancement in 2 cases after administration of contrast medium;④ the accompanied signs:proximate renal and ureteral presented distention,dropsy in different degrees,5 cases appeared delayed development.Conclusion 64-row spiral CT volume scan and 3D reconstruction with multiplane and multiorientation,combined with axial enhanced scan,can show lesions dimensionly and increase the dignostic accuracy in early primary ureteral carcinoma,which has an important value.

Carrying out targeting an oncolytic adenovirus strategy in gene therapy of pancreatic cancer is a new direction.Currently,related research including vitro test and animal models vivo test,targeted strategies on molecular biology and gene level are carried out.Some of oncolytic adenovirus drugs have entered phase Ⅲ clinical trials.Oncolytic adenoviruses alone or in combination with other treatments,can enhanced anti-tumor effect.

Objective　To investigate the alteration and clinical significance of NK cell and T lymphocyte subpopulatien in patients with rectal carcinoma. Methods　 The numbers of NK cell and T lymphocyte in 26 healthy persons and 35 rectal carcinoma patients were detected by 3H-releasing method and FCM. Results　NK cell and CD3, CD4, CD4/CD8 were decreased significantly in patients with rectal carcinoma (P<0.05), which was positively correlated with Dukes staging (P<0.01), and was inereased after redical or palliative operation (P<0.05), but NK cell and CD3, CD4, CD4/CD8 were further decreased in patients with unresectable tumor after operation (P<0.05). Conclusions　The immunity of rectal patients was decreased with the development of the disease, and it will be improved after radical of palliative operation.

OBJECTIVE To understand the situation of Mycoplasma infection and drug sensitivity in the patients of nongonococcal urethritis(NGU) in area of Yuebei. METHODS Totally 3 280 specimens in the patients of NGU were collected,cultured and tested for drug sensitivity. RESULTS From them there were 1 221 patients who had Mycoplasma(37.22%).The simple infection of Ureaplasma urealyticun(Uu) was 922 cases(28.11%) and Mycoplasma(Mh) 91 cases(2.77%),respectively.The mixed was 208 cases(6.34%).The result of drug sensitivity showed that sensitivity of Mycoplasma to josamycin was the highest,then was to levofloxacin(Cravit) and sparfloxacin.Ciprofloxacin was with the highest drug resistance,then were erythromycin and doxycycline. CONCLUSIONS Mycoplasma have high drug resistance to ciprofloxacin,erythromycin and doxycycline.The resistance rate to minocycline and clarithromycin is in a rising tendency.The antibiotics should be used reasonably to reduce the development of drug-resistant strains.

Forty-five male SD rats were divided into normal group, diabetic control group, and rosiglitazone treatment diabetic group.By the end of 12 weeks, the expressions of pigment epithelium-derived factor(PEDF), matrix metalloproteinase-2 (MMP-2), and transforming growth factor-β1 (TGF-β1) in the kidney were determined by immunohistochemistry and RT-PCR.The results showed that rosiglitazone decreased the increased kidney weight/body weight ratio, serum creatinine, blood ureanitrogen, urinary albumin excretion, triglyceride levels in diabetic rats (all P＜0.01).Rosiglitazone prevented the decreasing of protein expressions of PEDF and MMP-2 and the increasing of protein expression of TGF-β1 (all P＜0.01).PEDF mRNA showed a similar change,suggesting that renoprotection of rosiglitazone on diabetic rats may be mediated through regulating the expressions of PEDF, MMP-2, and TGF-β1.

Objective To explore the sensitivity and constancy of BNP in evaluating the therapeutic effect of congestive heart failure.Methods 80 patients made a definite diagnosis of congestive heart failure were selected and whose cardiac functional grading of NYHA,BNP and left ventricular ejection fraction (LVEF) were determined respectively pre-treatment,one week,one month and three months after-treatment.Statistical analysis on the difference of therapeutic effect was performed for each case.Results No statistical difference was found between the amplitude of BNP and LVEF in one week and on one month, three months pro-treatment by the scheme of captopril combining with metoprolol (P>0.05 ).But between the BNP and the cardiac functional grading,statistica difference was found in the fitst week pro-treament(P<0.05),when on one month and three months after treatment the statistical difference still not found(P>0.05).Conclusion BNP dynamic measuring had the hige sensitivity and constancy in quantitatively analysing the therapeutic effect of congestive heart failure which could be used as a reliable tool for evaluating the therapeutic effect of congestive heart failure.

BACKGROUND:At present, an increasing number of bone graft materials are inactivated using peracetic acid-ethanol solution, but there is no report on whether virus inactivation using peracetic acid-ethanol solution has effects on osteogenic induction of demineralized bone matrix. OBJECTIVE: To explore the effects of virus inactivation using peracetic acid-ethanol solution on the osteogenic activity of demineralized bone matrix. METHODS: Long bones of Sprauge-Dawley rats were selected to make demineralized bone matrix meal. A part of bone meal was placed into gelatin capsules and sterilized by60Coγ irradiation as control group; another part of bone meal was placed into gelatin capsules folowing virus inactivation using peracetic acid-ethanol solution, and then sterilized using60Coγ as experimental group. After that,40 Sprauge-Dawley rats were enroled, and gelatin capsules in the experimental and control groups were respectively implanted into the bilateral psoas muscles of the lumbar spine. At 2, 4, 6, 8 weeks after implantation, the bone grafts were removed for gross and histological observations. RESULTS AND CONCLUSION:At 8 weeks after implantation, the bone mass in the experimental group was not intact in shape with scattered particles, and under light microscope, a few of osteoblasts and new vessels were seen; the bone mass in the control group had hard texture and complete morphology, and under light microscope, mature bone trabeculae wrapped with osteoblasts and new vessels were visible and there were ful of fat cels and bone marrow cells between the bone trabeculae. The number of new microvessels in the experimental group was lower than that in the control group at different time (P < 0.001); at 8 weeks after implantation, the calcium content, alkaline phosphatase content, inorganic phosphorus content and new bone growth rate were all lower in the experimental group than the control group (P < 0.001). These findings indicate that peracetic acid-ethanol for virus inactivation has some negative effects on the osteogenic induction of demineralized bone matrix.
