Prostate cancer (PCa) incidence is increasing in China.Because of the limited clinical symptoms,early detection of PCa is critical and difficult.Current clinical diagnostic methods for localizing PCa including both the conventional anatomic imaging and histological techniques have many problems.Enormous novel PCa specific molecular probes have been evaluated.Those probes have substantially improved the diagnostic accuracy and specificity of PCa.This review briefly introduces the conventional noninvasive imaging techniques for PCa diagnosis.Nuclear medicine probes that have great clinical value for PCa molecular imaging are also discussed.

With its abilities of trans-synaptic tracing and self-replication and wide host range, pseudorabies virus (PRV) has been applied in the field of neuroanatomy since the 1970s. Four decades of PRV application have made many advances in researches on neuronal tracing with PRV. Mechanism studies focused on investigating infection of primary neurons and tracing direction in secondary neurons, while application studies focused on development of new pathological strains and innovation of tracing techniques. To date, the mechanism and application of viral tracing are not completely figured out yet. Integration of molecular biology technology will improve the efficiency in related researches.

AIM: To study the effect of extract from Pongamia pinnata roots on anti-inflammation and analgesia and acute toxicity. METHODS: The models of mice ear edema induced by xylene and Cotton pellet granuloma in rats to observe the anti-inflammation effect of PRE via oral administration. The effect of PRE on analgesia was tested by measuring the latent period licking hind foot with the hot plate method and counting body twisting induced by acetic acid in mice. The acute toxicity of PRE was measured by the method of Bliss. RESULTS: PRE could significantly inhibit the ear edema caused by xylene in mice, granuloma hyperplasia caused by cotton in rats. It could significantly prolong the pain threshold on hot-plate in mice, reduce the writhing times in mice. The LD50 of PRE was 6. 371 8 g/kg, its 95% confident limit was 5. 408 4-7. 723 2 g/kg. CONCLUSION: PRE has obvious effect on anti-inflammation and analgesia and the lower acute toxicity.

Objective To investigate the induction and function of circulating CD4+ CD25+ regulatory T cells(CD4+CD25+ Treg cells)in patients with chronic hepatitis B,and their role in the progress of chronic HBV infection.Methods Twenty two patients with chronic hepatitis B(CHB),11 patients with acute hepatitis B(AHB)and 20 healthy blood donators were enrolled in the study.After stimulating with recombinant HBV antigen or anti-CD3 mAb,the fraction of CD4+ CD25+Treg cells in peripheral blood mononuclear cells(PBMC)from different subjects was analyzed using flow cytometry.CD4+CD25+ Treg cells and effector cells(PBMC-Treg)were sorted out and cultured alone or together in vitro,and the cell proliferation and cytokines production were measured. Serum HBV titers,HBV markers and liver function were also evaluated.Results The fraction of circulating CD4+CD25+ Treg cells induced in PBMC from CHB patients under the stimulation of recombinant HBsAg was much higher than that in AHB patients(F=3.47,P<0.05)and normal controls(F=4.98,P<0.05).With HBsAg stimulation,cell proliferation and cytokines production (IFN-γand IL-10)of CD4+ CD25+ Treg cells either from patients or from normal controls was very low when cultured alone,and there was no significant difference between two groups(P>0.05).Cell proliferation and IFN-γproduction of effector cells from AHB patients were higher than those from CHB patients,however,when effector cells were cultured with CD4+Cd25+Treg cells at a ratio of 5:1,the cell proliferation and IFN-γ production were significantly inhibited (F=4.66,5.24,P<0.05).Conclusion Circulating nificantly suppress the production and IFN-γ production of effector T Cells,which may be associated with the progress of chronic HBV infection.

Objective To evaluate the value of endoscopic ultrasonography (EUS) in the diagnosis of Crohn's Disease (CD).Methods A total of 436 patients with endoscopically suspected CD underwent EUS and the clinical data of these patients were analyzed retrospectively.Changes of gastrointestinal wall stratification and perienteric complications detected by EUS were documented systematically.The consistency between the diagnosis of EUS and the results of pathology were recorded.Results A total of 297 cases of CD and 139 cases of non-CD were clinically diagnosed,while 277 CDs (including 17 non-CDs clinically diagnosed) and 159 non-CDs (including 37 CDs clinically diagnosed) were diagnosed by EUS.The sensitivity,specificity and accuracy rate of EUS in diagnosing CD were 87.5% (260/297),87.8% (122/139) and 87.6% (382/436),respectively.Dilated vessels in submucosa were detected in 40 patients,fistulae in 13,abscesses in 5 and enlarged lymph nodes in 75.Conclusion EUS can show gastrointestinal wall stratification of CD clearly with high diagnostic accuracy.Meanwhile,EUS can detect extraluminal complications well to help in providing useful information for surgery.

Objective To evaluate the value of differential diagnosis on congenital biliary atresia(BA) and infantile hepatitis syndrome(IHS) by technetium-99m-diethyl-iminodiacetic acid(99Tcm-EHIDA)hepatobiliary scintigraphy with phenobarbitol sodium.Methods Fifty-eight infants with persistent jaundice were taken phenobarbitol sodium[5 mg/(kg?d)] ,bid ?7 d).Those who had not bowel and gallbladders radioactivity within 24 hours were diagnosed as the diagnostic criterion of BA.Those with bowel and gallbladders radioactivity within 24 hours were diagnosed as the diagnostic criterion of IHS,who then received 99Tcm-EHIDA hepatobiliary scintigraphy with single photon emission computed tomography(SPECT) instrument.The results of all children were analyzed and compared with pathology and clinical follow up results.Results 99Tcm-EHIDA hepatobiliary scintigraphy correctly diagnosed 24 infants with last diagnosis BA and 29 infants with last diagnosis IHS,5 neonates false positive in all 34 IHS patients.The sensitivity in the diagnosis of BA was 100%,the specificity and accuracy were 85.3% and 91.4%,restectively.The sensitivity was 85.3% in the diagnosis of IHS;the specificity and accuracy were 100% and 91.4%,respectively.Conclusions 99Tcm-EHIDA hepatobiliary scintigraphy with phenobarbitol sodium can accurately differentiate BA and HIS at early stage.

Objective To deeply understand the risk factors of lymphedema for patients with breast cancer after surgery. Methods The phenomenological method was applied in this study. Semi-structured interview was used to collected data from 9 female breast cancer patients with lymphedema after surgery in our hospital from June to September 2016 for generic analysis. Results The risk factors of lymphedema could be categorized into four themes:(1)choice of treatment is the primary cause:axillary lymph node dissection; radiotherapy; chemotherapy; (2)not paying enough attention to lymphedema:lacking the knowledge of lymphedema; imbalance of physical activities for the affected limb; lacking awareness of exercise and protection of the affected limb. Conclusions Axillary lymph node dissection after radical surgery for patients with breast cancer is the primary cause of lymphedema, and paying not enough attention is an important factor, especially lacking the consciousness of prevention, so the nurses should emphasize education about prevention of lymphedema after surgery for patients, to improve the consciousness of them to reduce the occurrence of lymphedema and its influence on their quality of life.
