Objective To evaluate the efficacy of naloxone used in the postoperation of cerebral tumor.Methods Eighty patients were randomly assigned to receive (treated group:40 patients) or not re- ceive (control group:40 patients) naloxone.Both the two groups accepted the conventional therapy.Re- sults After operation,the content of?-EP,ET decreased continuously but the one of the treated groups was more obviously than that of the control groups (P

We present a rare case of colonic metastasis of renal cell carcinoma (RCC) and review the literature.A 54-year-old male was referred to our hospital with a history of bloody stools and fever.A dght kidney tumor measuring about 10 cm in diameter was found by abdominal computed tomography.Right radical nephrectomy and a right hemicolectomy with ileotransversostomy were performed.Pathological diagnosis was chromophobe RCC with sarcomotoid change involving the colon.Chromophobe RCC with sarcomotoid change is very rare.

OBJECTIVETo investigate the expression change of matrix metalloproteinase-9 (MMP-9) and nuclear factor-kappaB (NF-kappaB) induced by Xuemaitong capsule (XMT) preconditioning on rats of myocardial ischemia, and provide experimental evidence for the protection of XMT.

METHOD60 wistar rats were randomly divided into 5 roups: the control group, the model group, the three difference dose groups of XMT. The groups of XMT were treated by continuous 14 days intragastric administration. After 14 days, except the control group, all groups were continuous 2 days subcutaneous injected with isoproterenol 30 mg x kg(-1) every day. Before and 5, 10, 20, 30 minutes after subcutaneous injection, electrocardiogram were recorded, immunohistochemical staining, RT-PCR and image analysis were also measured for the investigation of the expression of MMP-9 and NF-KB in the ischemic region.

RESULTCompared with the model group, the delta sigma-ST of electrocardiogram of the high dose, middle dose, low dose groups of XMT decreased at different degree. Pathological conditions of ischemic myocardial ameliorated. The immunohistochemical staining and RT-PCR indicated that the expression of MMP-9 and NF-kappaB decreased in the high dose group (P < 0.05), the mRNA expression of MMP-9 and NF-kappaB decreased in the high dose group (P < 0.05).

CONCLUSIONThe expression of MMP-9 and NF-kappaB increased after myocardial ischemia After high dose treated by XMT, the expression reduction of MMP-9 and NF-kappaB indicated that XMT played an important preventive role in acute myocardial ischemia.

AIM:To compare CASIA SS-1000 and Sirius OCT sweep anterior segment analyzer instrument for measuring normal corneal vertex thickness (CCT) and the thinnest corneal thickness (TCT) results the difference,correlation and consistency,and provide a theoretical basis for clinical application.METHODS:This was a prospective study.A total of 34 normal subjects were collected.The subjects were measured by the same skilled operator.The SS-1000 OCT was first used,and then the corneal thickness was measured repeatedly by Sirius anterior segment analyzer.Paired t test and Bland-Altman were used to evaluate the consistency of corneal apex and corneal thinnest point between SS-1000 OCT and Sirius anterior segment analyzer.RESULTS:The mean corneal apex measured by SS-1000 OCT and Sirius corneal topography were 517.62± 25.29μm and 518.47±27.23μm CCT,respectively.The thinnest points of SS-1000 OCT and Sirius anterior segment analyzer CCT were 513.53±25.06μ m and 515.32± 26.69μm,respectively.Paired t test showed that the difference on corneal thickness of vertex was not statistically significant (P＞0.05),but the thinnest corneal thickness was statistically significant (P＜ 0.05).Pearson analysis of the two devices,the correlation is 0.969,0.965.The results of 95％ consistency limiting analysis on the corneal vertex thickness by Bland-Altman was (-14.22μm,12.52μm),that of the thinnest corneal thickness was (-15.61μm,12.03μm),4％ (3/68) was out of the 95％ consistency limiting,but the thinnest corneal thickness was of a little larger differences.CONCLUSION:SS-1000 OCT measurement of CCT and Sirius anterior segment analyzer is highly consistent,in clinical work can be considered alternative,but the thinnest point of the cornea can not be replaced each other.

Background and purpose:Intensity-modulated radiotherapy(IMRT) can significantly improve the dosimetric distribution of both the target and organs at risk compared to tangential irradiation for whole breast. However,its optimized methods remain different and conflicting for many radiotherapy institutions.In order to achieve the optimized planning of IMRT for the irradiation of intact breast,we investigated different optimizing methods in three dimensional radiotherapy planning system.Methods:Ten patients with early-stage breast cancer after breast conserving surgery were eligible for the study.Two kinds of plans were performed on each patient in three-dimensional treatment planning system,inverse planning IMRT and forward planning IMRT which included 3 different optimizing methods as manual optimizing(MO),multiple points optimizing(PO) and automated inverse optimizing(AO).Various parameters were used to evaluate the efficacy of different IMRT plans.All plans were compared using dose volume histograms(DVH) for the planning target volume(PTV) and organs at risk(OARs).Results:For MO,PO,AO forward plans and inverse plans,median number of segments were 5,5.5,5 and 20 respectively,and mean total MU were 225.8, 228.4,226.4 and 345.8 MU,respectively.Comparing the different forward planning optimizations,the best target coverage and dose homogeneity of PTV was observed in AO plans(P(?)0.01),and PO and AO plans showed a better reduction of OARs exposure compared with MO plans(P(?)0.05).A further improvement of dose homogeneity in the PTV and better sparing of OARs was achieved using inverse planning(P(?)0.05).Conclusion:Forward planning IMRT with AO optimization for intact breast irradiation could provide both efficacy and dosimetric advantages better than others.The inverse IMRT plan showed more potential in improving the dosimetric outcomes.However,further studies are required for inverse optimizing plans.
