Objective The purpose of this study was to observe the effects of bumetanide on elderly type 2 diabetic patients with middle and advanced stages nephropathy. Methods Forty cases with diabetic nephropathy (DN) were divided into two groups:control group (20 cases) and treatment group (20 cases) . The control group accepted furosemide (20 mg, once a day) and the bumetanide was orally administrated at the dose of 1.0 mg, twice a day to the treatment group for 3 months. The assessment of transferrin (TRF) and urine microalbumin (UALB) was performed at the time points at the end of 1, 4, 8, 12 weeks after treatment. Results (1) The levels of BUN, SCr and UA after treatment were lower than before treatment, but there were no significant differences. (2) In the treatment group, the levels of TRF and UALB have decreased after treatment for 1 week, with no statistically significant. But at the end of 4, 8 and 12 weeks,the differences were statistically significant ( <0.05) . Especially, during the three months follow-up,the levels of TRF and UALB at 12 weeks have decreased obviously. Conclusion The therapeutic effect of bumetanide on DN might be better than that of furosemide.

Purpose To investigate the diagnostic value of gray-scale ultrasound on ovarian cystic teratoma.Materials and Methods 83 patients with primary diagnosis of ovarian cystic teratoma underwent gray-scale ultrasonography. The ultrasonic images were compared with postoperative pathologic results. Results 91 cases of 83 lesions were detected. The ultrasonic features were categorized into 6 types: cystoid, solid-like, intracystic dough sign, intracystic hair-ball, intracytic fat-fluid level, and intracytic cluttering sign. The diagnose accordance rate for each sign was 81.0%, 77.8%, 96.2%, 100% and 70.0% respectively. The diagnose accordance rate of ultrasonic diagnosis compared with pathologic results was 89.0% (81/91), and misdiagnosed rate and rate of missing diagnosis was 11.0% (10/91). Conclusion The ultrasonic features of ovarian cystic mature terotoma were of importance diagnostic value, whereas differentiation with ovarian chocolate cysts and ovarian mucus-cystic adenoma should be made cautiously.

A 13-year-old female patient presented with itchy rashes on the right foot for 5 years. Skin examination revealed scattered flat, reddish-purple, slightly scaling papules on the inner side of the arch of the right foot, scattered light red papules on the outer side of the right great toe, and scattered domed reddish-purple papules on the right heel with collar-shaped keratinization around the base. Histopathological examination of the papule on the right heel revealed epidermal hyperkeratosis, marked hyperkeratosis around the papule, thickened granular layer and focal liquefaction degeneration of the basal layer with no obvious hyperplasia of the spinous layer; a large number of lymphocytes and plasma cells without atypia infiltrated the dermis, in which there were many small- and medium-sized dilated thick-walled blood vessels lined with prominent plump endothelial cells. The patient was diagnosed with acral pseudolymphomatous angiokeratoma of children, and treated with long-pulsed 1 064-nm Nd: YAG laser once every month. After 7 sessions of treatment, the rashes regressed and decreased in number.

PURPOSE: c-Met and its ligand, hepatocyte growth factor (HGF), play a critical role in oncogenesis and metastatic progression. The aim of this study was to identify inhibited enzymogram and to test the antitumor activity of SIM-89 (a c-Met receptor tyrosine kinase inhibitor) in non-small cell lung cancer. MATERIALS AND METHODS: Z′-LYTE kinase assay was employed to screen the kinase enzymogram, and mechanism of action (MOA) analysis was used to identify the inhibited kinases. Cell proliferation was then analyzed by CCK8 assay, and cell migration was determined by transwell assay. The gene expression and the phosphorylation of c-Met were examined by realtime-PCR and western blotting, respectively. Finally, the secretion of HGF was detected by ELISA assay. RESULTS: c-Met, activated protein kinase (AMPK), and tyrosine kinase A (TRKA) were inhibited by SIM-89 with the IC₅₀ values of 297 nmol/L, 1.31 µmol/L, and 150.2 nmol/L, respectively. SIM-89 exerted adenosine triphosphate (ATP) competitive inhibition on c-Met. Moreover, the expressions of STAT1, JAK1, and c-Met in H460 cells were decreased by SIM-89 treatment, and c-Met phosphorylation was suppressed in A549, H441, H1299, and B16F10 cells by the treatment. In addition, SIM-89 treatment significantly decreased the level of HGF, which accounted for the activation of c-Met receptor tyrosine kinase. Finally, we showed cell proliferation inhibition and cell migration suppression in H460 and H1299 cells after SIM-89 treatment. CONCLUSION: In conclusion, SIM-89 inhibits tumor cell proliferation, migration and HGF autocrine, suggesting it's potential antitumor activity.

A 25-year-old female patient presented with itchy rashes on her feet for 10 years. Skin examination showed dark red plaques with clear boundaries, whose surfaces were covered with grey-brown scales, on the dorsum of toes and adjacent dorsum of the feet, the extensor aspect of the right ankle and the left Achilles tendon. Laboratory tests revealed that serum anti-hepatitis C virus (HCV) antibody was negative and HCV-RNA quantity was normal. Histopathological examination showed epidermal hyperkeratosis with parakeratosis, irregularly thickened spinous layer, scattered dyskeratotic cells and necrotic keratinocytes in the middle and upper spinous layer, focal liquefaction degeneration of basal cells, dilatation of small blood vessels in the superficial and middle dermis, and perivascular infiltration of a small number of lymphocytes. The patient was diagnosed with necrolytic acral erythema without hepatitis C. After 2-month treatment, the skin lesions completely regressed, and hyperpigmentation remained.

Medical rescue bases for nuclear or radiological emergencies are mostly composed of institutions that have obtained the qualification of radiological health technical service (Class A) or the qualification of radiation-induced disease diagnosis. Institutions of radiological health have accumulated the technical capabilities of radiation monitoring, contamination detection, dose estimation, and health effects evaluation in their daily work, which can play an important role in the response to nuclear or radiological emergencies and realize the “combination of non-emergency and emergency use” in capacity building. It is suggested that institutions of radiological health at all levels should continue to take advantage of their strengths, improve their capabilities through participating in radiation monitoring projects, and actively participate in the assessment of assay capabilities of institutions of radiological health, so as to provide personnel and technical reserves for the health response to nuclear or radiological emergencies.
