Objective To investigate the clinical value of PET-CT scans in lymphomatous patients in post-therapy evaluation. Methods 18F-FDG PET-CT imaging were performed in 40 lymphomatous patients whom had been received therapy. Successive PET-CT imaging were performed in 5 cases, and the treatment was evaluated with clinical evaluation. Results Successive PET-CT imaging were performed in 5 cases, in which the tumor was eradicated in 2 cases, improved in 2 cases, and relapsed in 1 case. In 35 patients PET-CT imaging was repeated after treatment, among them 30 cases with complete or partial remission, and PET-CT imaging was positive in 25 cases. PET-CT imaging was still positive in 8 cases with recurrent or remnant tumor. PET-CT imaging changed the therapeutic regime. Conclusion PET-CT imaging can detect the recurrent or remnant tumor sensitively and accurately. There is a significant value for the guidance of clinical therapeutic.

Objective To observe the effects of low frequency electrical stimulation (LFES) on the proliferation of endogenous brain neural stem cells (NSCs) and on the expression of basic fibroblast growth factor (bFGF)and epidermal growth factor (EGF) in rats with acute cerebral infarction; to explore the therapeutic mechanism of LFES in improving neural function. Methods Fifty-four rats were randomly divided into a LFES group, a placebo stimulation group and a sham-operated group. Each group was further divided into 3rd day, 7th day and 14th day subgroups, with 6 rats in each subgroup. An acute cerebral infarction model was induced in the rats of the LFES and placebo stimulation groups by middle cerebral artery occlusion (MCAO). Three days after the operation, rats in the LFES group began LFES treatment (frequency 30 Hz, pulse width 250 μs, current intensity 3 mA, 10 min/d) ,while the placebo stimulation group was treated identically but without electricity. The rats in the sham-operated group had no special treatment. The expression of nestin positive cells in the subgranular zone of the hippocampus and the subventricular zone was detected by immunohistochemical staining. The expression of bFGF, EGF proteins and mRNA in the ischemic hemisphere was detected by Western blotting and RT-PCR analysis. A screen test was applied to evaluate motor function. Results Nestin-positive cells in the subgranular and subventricular zones of rats in the LFES group increased significantly more than in the placebo stimulation group at the 7th and 14th day. The expression of bFGF, EGF proteins and mRNA in the ischemic hemisphere was up-regulated compared to the placebo stimulation group at the 7th and 14th day. At the 14th day a difference in motor function was observed in rats in the LFES group compared with the placebo stimulation group. Conclusion LFES can promote the proliferation of endogenous brain NSCs and the expression of bFGF and EGF in rats with acute cerebral infarction. It can also improve motor function and enhance neural plasticity in the brain.

Objective To explore an optimal treatment and to study the prognosis related factors of breast cancer patients with local recurrence after mastectomy. Methods From 2002. 7 to 2005. 2, 477female patients with loco-regional recurrence of breast cancer treated in Tianjin Cancer Hospital were analyzed retrospectively. Results In 477 cases, recurrence within 1 year after mastectomy accounted for 26. 2% , recurrence within 2 years accounted for 61. 2%. There were 310 cases with metastasis after local recurrence was diagnosed, accounting for 65.0%. 5-year total survival rate after recurrence is 48.4%.Local control rates varied in subgroups with different recurrence site, clinical subtypes, radiotherapy fields,with or without radiotherapy, surgical resection or excisional biopsy ( P<0. 05 ). There was a statistical difference in distant metastasis rate and 5-year survival rate among subgroups which had different clinical stage of primary tumor, disease-free interval, clinical subtypes or treatment methods ( P<0. 05 ). Simplistic treatment option, late clinical stage of primary tumor and triple-negative breast cancer were the independent factors predicting poor prognosis for recurrent breast cancer ( P<0.05 ). Conclusions Multi-site recurrence and triple-negative breast cancer lead to a poor local control. Local expansion of radiotherapy combined with surgery improves the local control rate. Patients with late clinical stage of primary tumor,recurrence within 2 years, triple-negative breast cancer are likely to have distant metastasis when recurrence is diagnosed. Combined treatment program improves survival rate.

Objective To compare the clinical value of 18F-FDG PET imaging and 99Tcm-MDP whole body bone imaging in detection of bone metastases. Methods 43 patients were undergone 18F-FDG PET and 99Tcm-MDP imaging within 2 weeks. 28 of them were with confirmed bone metastases by other examinations or follow-up and the remaining 15 were confirmed without bone metastases. The results of the 2 different modalities were analyzed. Results Among 28 patients with confirmed bone metastases, PET and MDP accurately diagnosed 26 and 27, respectively. The sensitivity of them were 92.9 %(26/28), 96.4 %(27/28), Among the remaining 19 cases without bone metastases, PET and MDP correctly gave 14 and 8 negative results, respectively. The specificity of them were 93.3 %(14/15), 53.3 %(8/15), and accuracy of them were 93.0 %(40/43), 81.4 %(35/43). The differences between specificities and accuracies of the two methods were significant, while no significant difference between the sensitivities of the two methods. Conclusion For the detection of bone metastases in patients with malignant tumors, 18F-FDG PET showed a similar sensitivity but better specificity and accuracy compared with 99Tcm-MDP bone scan. For patients with suspected bone metastases, negative finding or single hot spot in 99Tcm-MDP imaging, 18F-FDG PET imaging was recommend as a further and complementary assessment of bone metastases.
