Objective To evaluate the clinical role of F-18 fluorodeoxyglucose (FDG)-positron emission tomography (PET) for the diagnosis and staging of prostate cancer.Methods 18F-FDG PET/CT and 99Tcm-MDP ECT whole body bone scan were both performed in 40 patients with prostate cancer proved by biopsy or surgery.We then evaluated the diagnostic value of 18F-FDG PET/CT for prostate cancer.Results Of 40 cases,17 cases were detected by 18 F-FDG PET/CT with a sensitivity of 42.5％.Of the 17 cases with lymphoma metastasis,8 cases were detected by CT while 15 cases were detected by 18F-FDG PET/CT.The sensitivity of 18F-FDG PET/CT is 88.2％.Though 18F-FDG PET/CT and 99Tcm-MDP bone scan have a similar sensitivity in detecting bone metastases,18 F-FDG PET/CT has better specificity and accuracy in detecting bone metastases than that of an 99Tcm-MDP bone scan.Conclusions Though the diagnostic value of 18F-FDG PET/CT in detecting primary focus of prostate is limited,it still has an important role in detecting lymph node metastases and bone metastases.18F-FDG PET/CT has its superiority in prostate cancer staging.It can also help clinicians to select the regimen of treatment.

Objective To investigate the effects of rosiglitazone on proangiogenesis function of human umbilical vein endothelial cells ( HUVEC) in high glucose environment. Methods HUVECs were cultured in high glucose environment and stimulated by rosiglitazone. MTT, cell scratch test and Transwell assay were used to detect HUVEC proliferation and migration. The concentration of VEGF, SDF-1 was also detected in the supernatant. Results Rosiglitazone could effectively promote HUVEC proliferation and migration. The concentration of VEGF and SDF-1 in rosiglitazone stimulated supernatant was higher than that in high glucose group. The inhibition of AKT signal could block the promotion of rosiglitazone on the HUVEC proliferation, migration and secretion. Conclusion Rosiglitazone could significantly promote HUVEC secretion, proliferation and migration in high glucose environment. AKT signal played an important role in this process.

Abstract: Objective To analyze the changes of coagulation indicators in patients with hepatitis B complicated with Clonorchis sinensis (C. Sinensis), and provide reference value for diagnosis, drug using and prognosis monitoring. Methods　The patient samples were collected from the Third Affiliated Hospital of Sun Yat-sen University from June 2018 to February 2022 and divided into six groups. They were 40 healthy patients, 47 patients with simple chronic hepatitis B, 47 patients with post-hepatitis B liver cirrhosis, 40 patients with C. Sinensis mono-infection, 30 patients with chronic hepatitis B patients co-infected with C. Sinensis and 27 patients with post-hepatitis B liver cirrhosis patients coinfected with C. Sinensis. Four coagulation indexes, prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT) and fibrinogen (FIB), were detected and compared among the groups. Results Compared with the healthy group, C. Sinensis mono-infection group had higher level of FIB and delayed PT, APTT; chronic hepatitis B group and chronic hepatitis B patients co-infected with C. Sinensis group had delayed PT, APTT, TT and significant lower FIB, these differences were statistically significant (all P<0.05). Compared with simple chronic hepatitis B group, post-hepatitis B liver cirrhosis and chronic hepatitis B patients co-infected with C. Sinensis had significant delayed PT, APTT, TT and lower FIB (all P<0.05). Compared with the post-hepatitis B liver cirrhosis and chronic hepatitis B patients co-infected with C. Sinensis, post-hepatitis B liver cirrhosis patients coinfected with C. Sinensis group had significant delayed PT, APTT, TT and lower FIB (all P<0.05). Conclusions The coinfection of C. Sinensis will further aggravate the coagulation dysfunction of HBV patients, leading to poor treatment and prognosis. HBV patients will have worse coagulation function in the process to post-hepatitis B liver cirrhosis; Therefore, it is important to pay attention to C. Sinensis co-infection when treating HBV patients, so that further guidance on clinical use and monitoring of prognosis can be provided.

AIM To study whether inhibition of semicarbazide (Sem)-sensitive amine oxidases (SSAO) attenuates myocardial ischemia-reperfusion (I-R) injury. METHODS Male Sprague-Dawley rats were randomly divided into 4 groups. Each group consisted of 10 rats. Sham group: the ligature was placed under the left coronary artery (LCA), but not ligated. Sham+Sem group: Sem (30 mg·kg-1, ip) was given 10 min prior to the experiment, the LCA ligature was not ligated. I-R group: the LCA was occluded for 30 min and reperfused for 180 min. I-R+Sem group: Sem (30 mg·kg-1, ip) was given 10 min prior to the experiment, and then 30 min ischemia followed by 180 min reperfusion. Myocardial infarct size was determined by using nitroblue tetrazolium staining. Plasma creatine kinase (CK) and myeloperoxidase (MPO) activities, and malondialdehyde (MDA) and hydroxyl radicals levels were determined by spectrophotometer. Plasma SSAO activity was determined by high performance liquid chromatography. HE staining was used for histopathological evaluation. RESULTS There were no significant differences on each index between sham and sham+Sem groups. Plasma MPO and SSAO activities, and MDA and hydroxyl radials levels significantly increased in I-R group, compared with sham group. Myocardial infarct size was remarkably smaller in I-R+Sem group (27.7±3.7)%, compared with I-R group (43.2±3.1)%. Plasma MDA level, MPO activity and hydroxyl radical level were lower in I-R+Sem group than those in I-R group, from (27.5±9.3) μmol·min-1·L-1,(2.6±0.4)mmol·L-1 and (628±50)mmol·min-1·L-1 down to (14.2±5.6)μmol·min-1·L-1,(1.7±0.5)mmol·L-1 and (503±88)mmol·min-1·L-1, respectively. Histological results showed that inhibition of SSAO activity significantly attenuated leukocyte infiltration. CONCLUSIONPlasma SSAO activity is increased in myocardial I-R injury and inhibition of SSAO can attenuate myocardial I-R injury.
