Purpose To explore the value of 64-slice spiral CT digital subtraction angiography in diagnosis of cerebral arteriovenous malformations (AVM).Materials and Methods 26 patients with AVM were performed with plain CT scan, enhanced arterial phase and venous phase CT scan on a 64-slice spiral CT scanner. The subtracted arterial phase data was obtained through subtracting the plain CT images from arterial phase images, then the subtracted venous phase data was obtained through subtracting arterial phase images from venous phase images, and subtracted mixed arterial-venous phase data through subtracting plain CT images from venous phase images. Then volume rendering (VR) and maximum intensity projection (MIP) were used to reconstruct the cerebral vessel images. Results The inference of cranial bones was completely removed in all subtracted cerebral vessel images, thus clearly demonstrating malformed vascular nest, feeding arteries and draining veins. And 7 malformed temporal vascular nests, 5 parietal vascular nests, 5 frontal vascular nests, 6 occipital vascular nests and 3 cerebellar vascular nests were revealed;39 feeding arteries were detected altogether. Single feeding artery was found in 15 cases, and multiple feeding arteries in 9 cases. Meanwhile 33 draining veins were observed, and single draining vein was found in 10 cases, multiple veins in 16 cases.Conclusion 64-slice subtraction angiography can remove the inference of cranial bones and clearly demonstrate the feeding arteries, malformed vascular nests, draining veins, potentially providing a reliable evidence for therapeutic planning and postoperative follow-up.

This paper summarizes the intervention of chronic kidney disease at home and abroad from the intervention places, objects, contents, methods, executants and evaluation. Some intervention problems have been found in this paper: intervention places do not extend to the basic medical institutions; we draw less attention to those patients with special health needs; the theoretical basis of intervention strategies is inadequate; the content and evaluation of intervention are not comprehensive. The intervention research of chronic kidney disease in China is still a long way to go.

BACKGROUNDThe efficacy of chemotherapy alone is still unsatisfactory in the treatment of advanced non-small cell lung cancer (NSCLC). Some kinds of solid tumors have showed good responses to chemotherapy combined with hyperthermia. This study is to investigate the feasibility and the response of hyperthermia combined with chemotherapy for advanced NSCLC.

METHODSA total of 51 patients with advanced NSCLC were eligible, in which 22 were in group HC, and the other 29 in group C. Patients in the two groups received NP (vinorelbine+cisplatin) or GP (gemcitabine+cisplatin) regimen for 2 cycles. In addition, patients in group HC received local hyperthermia twice a week, up to 12 times.

RESULTSThe response rate in group HC was 22.7%, and 13.8% in group C (P > 0.05). The clinical benefit rate in group HC was significantly higher than that in group C (P < 0.05). There was no difference in change of KPS score after treatment between the two groups.

CONCLUSIONSHyperthermia combined with chemotherapy shows good tolerance and response in patients with advanced NSCLC. Further study should be carried out.
