Objective To determine whether the use of 18F-FDG PET/CT alters staging and management of nasopharyngeal carcinoma (NPC) when compared with MRI staging practice;and to explore the relation of standard uptake value (SUV) of 18F-FDG PET/CT and the pathological classification and T staging of NPC. Methods The study was performed retrospectively on a group of 41 patients with a new diagnosis of NPC. All the patients underwent whole body PET/CT scanning and head & neck MRI scanning within 3 weeks of each other. The AJCC protocol was introduced to stage NPC and the results of the PET/CT were compared with MRI based on pathologic diagnosis. Results ①Primary tumor:the accuracy of T staging of PET/CT was significantly higher than MRI (85.37% vs 60.98%,U=2.49,P

Objective To observe the expression of thioredoxin (Trx) and thioredoxin-interacting protein (Txnip) in the kidney of type 2 diabetic rats induced by streptozotocin and the effect of probucol treatment on thioredoxin system. Methods Thirty male SD rats were divided into control group( C, n = 10), diabetes group ( D, n =10), and probucol treated diabetic group ( P, n = 10). After eight weeks of probucol treatment, the expressions of Trx and Txnip in the kidney of three groups were measured by RT-PCR, Western blot, and immunohistochemistry. Body weight,24 h microalbuminuria( ALB), fasting plasma glucose( FPG), fasting insulin( HNS), blood urea nitrogen (BUN), creatinine (Cr), malondialdehyde ( MDA ), superoxide dismutase ( SOD ), and catalase (CAT) were determined. Results Compared with group C, Trx was markedly decreased in group P (0. 162 ±0. 008 vs 0. 239 ±0. 006, P＜0.05 ), while Txnip was significantly increased (0. 159±0.003 vs 0. 091 ±0.016, P＜0.05 ). Trx in group P was increased as compared with group D (0. 162 ±0. 008 vs 0. 108 ± 0. 013, P ＜ 0. 05 ), while Txnip was lowered (0. 159±0.003 vs 0. 236±0.009 ,P＜0.05 ). FPG, 24 h ALB, BUN, Cr,and MDA levels in group D were markedly increased as compared with group C (P＜0. 05), while the activity of SOD, CAT, and FINS levels were decreased apparently (P＜0.05). The above markers except for FPG in group P were ameliorated (P＜0. 05 ).Conclusions Probucol attenuated oxidative stress by means of partially restoring Trx function and reducing Txnip expression, and thus played a major role in renoprotection of type 2 diabetic nephropathy.

Paired basic amino acid cleaving enzyme 4 (PACE4),a subtilisin-like endoprotease,which is thought to play a significant role in tumor occurrence and development.Its over or low expression may lead to enhanced proliferation and invasion of tumor cells,and even increase the malignant degree.The specific regulation according to the roles of PACF4 expression in different tumors may be helpful for tumor treatment and prognosis improvement.

ObjectiveTo evaluate the role of galactomannan (GM) detection in bronchoalveolar lavage fluid (BALF) in the diagnosis of invasive pulmonary aspergillosis (IPA) in elderly patients with lung diseases.MethodsThe elderly patients with lung diseases and suspected of having IPA were enrolled. BALF for culture and GM detection, and serum samples for GM detection were obtained from all participants.According to European Organization for Research and Treatment of Cancer/Mycoses Study Group (EORTC/MSG) with host factors, clinical criteria, mycological evidence and histological or cytopathological evidence, all patients were categorized into the proven, probable,possible and no IPA patients. The IPA patients were considered as IPA group while no IPA was considered as control group. ResultsAmong 76 enrolled elderly patients, 18 cases were diagnosed with IPA (1 proven, 11 probable and 6 possible), the remained 58 patients were as control group.Based on a GM index cutoff value of ≥0. 5, the sensitivity, specificity, positive predictive value and negative predictive value for BALF were 83.3％, 82. 8％, 60.0％ and 94.1％, respectively; these variables in serum were 55.60％ , 91.4 ％, 66.7 ％ and 86.9％ , respectively. Using a GM index cutoff value of ≥1.0, the specificity and positive predictive value of both BALF GM and serum GM reached 100％, but the sensitivity and negative predictive value of BALF GM were higher than serum GM (66.7％ vs. 22.2％, 90.60％ vs. 80.60％, respectively). Receiver operating characteristic curve analysis yielded a sensitivity of 83.4％ and a specificity of 96.6％ at a BALF GM index cutoff value of ≥0.725. ConclusionsGM detection in BALF seems to be a useful tool in the diagnosis of IPA in elderly patients with lung diseases,and could be widely used in future.
