Detection of prostate specific antigen (PSA) is the most commonly used screening method for prostate cancer. However, many studies have found that the false positive rate and false negative rate of PSA detection for prostate cancer screening are very high, which easily leads to the overuse of PSA detection. Autoantibodies appear at the early stage of cancer, accompany the occurrence and development of prostate cancer. Autoantibodies have a long half-life and are easy to detect. Existing studies have found that autoantibodies can be used in the diagnosis of prostate cancer, and correlated with some prognostic indicators such as Gleason grade and overall survival (OS) of prostate cancer patients. This paper summarized 8 studies on the role of single autoantibody in the diagnosis and prognosis of prostate cancer. Most of the reported single autoantibodies have better diagnostic performance than PSA, and combined application could improve the diagnostic performance. Some autoantibodies are related to a poor prognosis of prostate cancer.

Objective To review and summarize the effects of interventional treatment of hand arteriovenous malformation in 5 cases.Methods Through catheterization of brachial artery ipsilaterally the blood-supply artery of arteriovenous malformation was embolized,using high-temperaure managed gelatin sponge,silk thread,pingyangmycine and spring coil.Results Total 13 blood-supply arteries in 5 cases were embolized with successful rate of 100%,including 1 case of complex malformation under effectively controlled,3 cases cured clinically and 1 case still awaiting observation.Conclusions Transcatheter arterial embolization for the treatment of hand arteriovenous malformation is safe,effective and high successful.(J Intervent Radiol,2007,16:277-279)

Objective To investigate effects of magnetic stimulation on apoptosis of nerve cells and the production of inducible nitric oxidate synthase (iNOS) after spinal cord injury (SCI). Methods Thirty-two SpragueDawley male rats were randomly divided into a magnetic stimulation group (n = 16) and a control group (n = 16).SCI models were established by spinal cord transection in both groups. Rats were sacrificed at the 6th, 12th, 24th and 72nd hour post-injury, but the rats in the stimulation group received magnetic stimulation before being sacrificed.Apoptosis index (AI) and iNOS-positive cells rate were recorded at each time point. Results Apoptotic cells could be observed by the 6th hour post-injury, and were elevated from the 24th to the 72th hour. iNOS-positive cells were few at the first two time points, but had increased significantly at the 24th and 72nd hour post-injury. Compared with the control group, the apoptosis index of the stimulation group decreased a little at the 6th and 12th hour, but not significantly. The difference was quite significant at the 24th and 72nd hour, however, and the AI in the stimulation group decreased much more than that in the control group. There was little difference in the rate of iNOS-positive cells between the control and stimulation groups at any time point. Conclusions Magnetic stimulation could inhibit neural apoptosis and protect neurons from secondary SCI, but it has little effect on iNOS production.

Objective To study whether suprachiasmatic nucleus (SCN) slices are able to induce the molecular oscillations in NIH/3T3 fibroblast. Methods SCN slices from 10-day-old SD rat and NIH/3T3 cells were co-cultured in a serum-free condition. 24h mRNA profiles of Per1 and Rev-Erbα were measured in NIH/3T3 cells using real-time PCR. Results After co-cultured for 6 days, ten SCN slices can induce the significant daily oscillation of Per1 and Rev-Erba mRNA expression in NIH/3T3 cells (P<0.01). The peak time Rev-erbα and Per1 were at CT5 and CT11 respectively. Rev-Erbα oscillations were significant even with two SCN slices and 2 days co-culture (P<0.05). In contrast, Per1 expression fluctuation was not observed until more than 6 days of co-culture and with six SCN slices (P=0.031). Conclusion Diffusible signals release from SCN slices can regulate molecular rhythms in cultured fibroblasts. Rev-Erbα and Per1 don't start to oscillate at the same time, and Rev-Erbα is more sensitive to SCN signal.

Objective To study the factors influencing the recurrence of aggressive fibromatosis(AF) patients.Methods Analyze clinical features and find out factors affecting AF recurrence with univariate and multivariate analysis. Results One hundred and three AF patients were analyzed. Diameter of all the masses was (7.84?5.62)cm. 98.2% of all patients received surgery and radical resection rate is 79.4%. First recurrent time after surgery of male and female is (1563?377) and (2117?3704) days for male and female cases respectively,it's (2723?461),(657?262),(2090?499),(812?220) and (721?234) days for that of abdomen wall、head and neck(H & N),deep mass,joints and chest wall. Recurrent time is (2232?271) and (1347?267) days for those with or without surgery history patients. Univariate analysis showed that gender,tumor site and surgery history of tumor site are prognostic factors of tumor recurrence. Multivariate analysis suggest that only surgery history of tumor site is an independant prognostic factors of AF recurrence after surgery. Conclusion Gender,tumor location and surgery history of tumor site can be valuable to predict postsurgery recurrence of AF.

AIM: To observe the protective effect of heat stress preconditioning on endothelial cells under anoxia and explore its mechanism. METHODS: The endothelial cells were divided into 4 groups: (1) anoxia; (2) heat stress; (3) heat stress preconditioning + hypoxia; (4) control. LDH activity was measrued by using Automatic Biochemistry Analysis-Meter. Cell death rate was determined by trypan blue, NO production was tested by measuring NO - 2/NO - 3 content in cellular culture medium by using Griess assay. RESULTS: LDH release and cell death rate of the anoxia endothelial cells significantly increased compared with control; 39℃ heat stress preconditioning reduced those increment by 29、47%, 33.67% respectively. 41℃ heat stress preconditioning has no protection against the anoxia-induced injury in endothelial cells. The NO production in anoxic endothelial cells decreased markedly. 39℃ heat stress preconditioning induced the increase in NO production in endothelial cells, but 41℃ heat stress preconditioning made the NOS activity decrease. The NO production was correlated negatively with LDH release and cell death rate in anoxic endothelial cells. CONCLUSION: The heat stress preconditioning within the limits can protect the endothelial cells from anoxia injury. The increase in NO in endothelial cells may play an important role in the mechanism of the protective effect.
