Objective To investigate the feasibility and efficacy of combined preoperative chemora- diation program followed by radical surgery in bulky early or moderate uterine cervical cancer.To determine the incidence and predictive value of rasidual disease in the radical hysterectomy specimens after CCR. Methods Thirty-five patients with uterine cervix carcinoma from January 2001 to September 2003 were treated with preoperative external beam radiotherapy to 3060 cGy in 4 weeks.Patients received concurrent continuous infusion cisplatin(20 mg/m~2)on day 1,8,15,22 of four weeks and 5-Fu(4 g)chemotherapy during the first four days and the last four days of the radiation course.Radical surgery was not performed until 4 weeks after the completion of the preoperative treatment.Results Clinical response was 85.71%,complete response,54.29 %;partial response,31.43 %.The analysis of the surgical specimens showed 19 patients had revealed residual disease and 16 patients had revealed no residual disease,the complete pathological response hed been 45.71%.Three-year survival rate was 87.14 % in 35 patients.Three-year survival rate of residual disease patients(76.32 %)was significantly lower than that of no residual disease(100.0 %)(P=0.0358). Three-year survival of cervical stromal invasion less than 1/2 and invasion extra stromal was 100.0 %, 41.67 % respectively(P=0.0109);three-year survival of lymph-vascular space involvement and no lymph- vascula space involvement was 0,85.29 %,respectively(P=0.0148).Conclusion Combined preoperative chemoradiation program followed by radical surgery in bulky early or moderate cervical cancer could reveal an effective efficacy with a tolerant complication.Residual disease is an independent and strong predictive factor.

Objective To study the clinical features of diagnosis and treatment in children with low-risk myelodysplastic syndrome(MDS) and improve the diagnosis and treatment.Methods The examinations of 17 children with low-risk MDS were analyzed.The blood concentrations of cyclosporine,one of the therapeutic drugs,were monitored and the responses to the treatments were evaluated.Results Exa-mination of full blood count showed that the reductions of 3 cell types,2 cell types and 1 cell type were 11 (64.7%)cases,5(29.4%)cases and 1(5.9%)case,respectively.Reticulocyte count showed an increase in 82.4% of the patients and normal in 3 cases.Fourteen in 17 cases were hyperplastic marrow and 3 cases were hypoplastic marrow.Among all cases,one lineage,2 lineages and 3 lineages dyspoiesis were seen in 8(47.1%),7(41.2%) and 1 (5.9%)cases,respectively.One case showed no dyspoiesis.Cytogenetics examination showed normal in 10(58.8%) cases and abnormal in 7(41.2%) cases.Fifteen (88.2%) cases had normal proportions of CD59 negative cells,while 2 cases had higher proportions.The blood concentrations of cyclosporine that were tested in 9 cases at the end of the third week were in a range of 95.3-316.5 ?g/L.The therapeutic effect of 10 cases were evaluated at the end of the third month after being treated.Eight cases achieved haematological improvement and 2 cases didn′t.The rate of improvement was 80%.Conclusions The patients of low-risk MDS are mostly school-aged children and pancytopenia is the most common sign.The combination of predisone,cyclosporine and stanozolol agents shows good effect to treat low-risk MDS.The absorption of cyclosporine is different individually,so it is significant to adjust the dosage of cyclosporine according to the concentration regularly in clinical practice.

Background and purpose:Although FDG tumor imaging has been applied in clinic widely, dual-phase imaging can provide much more information about the FDG uptaking of pulmonary lesions. The purpose of the study was to evaluate the usefulness of dual-phase18F-FDG coincidence detection SPECT/CT imaging in the differential diagnosis of the pulmonary lesions.Methods:There were 28 patients with pulmonary lesions which were detected by CT. All the patients undertook the SPECT/CT imaging at 2 time-phases respectively: early imaging at 40-60 min and delayed imaging at 2-3 h after the intravenous injection of FDG. Data processing: calculating the radio of T and N in early and delayed imaging respectively; T: The radioactive count of the lesions; N: The radioactive count of the normal tissue; and the change rate:ΔT/N. ROC was used to ifnd out the threshold of T1/N1, T2/N2及ΔT/N in the differential diagnosis between benign and malignant lesions. AUC was used to evaluate the diagnosis value of the dual-phase and single-phase imaging.Results:The threshold of T1/N1 in early imaging was 2.65, whereas AUC was 0.767. The sensitivity, speciifcity and accuracy were 83.3%, 30% and 64.3%, respectively. The threshold of T2/N2 in delayed imaging was 3.14, whereas AUC was 0.847. The sensitivity, speciifcity and accuracy were 94.4%, 60.0% and 82.1%, respectively. The threshold ofΔT/N in delayed imaging was 16.9%, whereas AUC is 0.950. The sensitivity, speciifcity and accuracy were 88.5%, 71.4% and 86.2%, respectively.Conclusion:Dual-phase18F-FDG coincidence detection SPECT/CT imaging has much higher accuracy and speciifcity. However it still has false positivity, and should be analyzed with CT and clinical history.

Objective: To analyze the correlation of miR-625 expression with clinicopathological characteristics in esophageal squa-mous cell carcinoma (ESCC) and to explore the effect of miR-625 on the migration and proliferation of ESCC cells. Methods:The expres-sion level of miR-625 was determined through real-time PCR in 86 paired human ESCC tissue specimens and tumor-adjacent normal esophageal tissue specimens, ESCC cell lines, and esophageal epithelial cell line. The associations of miR-625 expression with clinico-pathological characteristics and survival in ESCC patients were analyzed. Transwell and CCK-8 assays were performed to examine the effect of miR-625 expression on migration and proliferation of ESCC cells. Results:Compared with tumor-adjacent normal specimens, miR-625 was significantly downregulated in ESCC tissue specimens (P<0.05). MiR-625 expression was decreased in ESCC cell lines com-pared with human esophageal epithelial cell lines (P<0.05). Lower miR-625 expression was associated with poorer prognosis and sur-vival. The migration and proliferation abilities of ESCC cells were inhibited by miR-625 overexpression (P<0.05). Conclusion:MiR-625 acts as a tumor suppressor gene in the development and progression of ESCC, suggesting that miR-625 may serve as an efficient prog-nosis biomarker and a potential therapeutic target for ESCC.

Objective To observe the effects of berberine on inflammatory factors, adipokines and fatty acid metabo-lism in 3T3-L1 adipocytes, and to investigate the molecular mechanism underlying berberine’s role of improving insulin re-sistance. Methods mRNA level of inflammatory molecules, adipokines, key enzymes and protein in fatty acid metabolism in 3T3-L1 cells were determined by quantitative real time polymerase chain reaction (qRT-PCR) after cells were treated with different concentrations of berberine (0, 5, 10, 20, 40μmol/L) for 24 hours and with 10μmol/L berberine at different du-rations (0,4,8,24,48 h). These factors mainly included interleukin-6 (IL-6), tumor necrosis factor-α(TNF-α), leptin, adipo-nectin, visfatin, fatty acid synthase (FAS), acetyl-CoA carboxylase (ACC), adipose triglyceride lipase (ATGL) and adipocyte fatty acid binding protein (AFABP). Results In 3T3-L1 adipocytes, transcription level of IL-6, TNF-α, leptin, FAS, AT-GL, AFABP reduced with addition of berberine dosage at 10~40μmol/L(P＜0.05)while visfatin mRNA level increased(P＜0.05)compared with the control group. No significant difference was found in expression of adiponectin(P>0.05). Tran-scription level of IL-6, TNF-α, leptin, AFABP, ATGL, FAS decreased with time after 10μmol/L berberine intervention (8-48 h) compared with the control group(P＜0.05). On the other hand, visfatin mRNA level increased(P＜0.05)compared with the control group. Adiponectin mRNA decreased only after cells were treated with berberine for 48 h(P＜0.05). No sig-nificant difference was found transcription of ACC between each groups treated with berberine(P > 0.05). Conclusion mRNA level of inflammatory factors, adipokines, key enzymes and protein in fatty acid metabolism in 3T3-L1 adipocytes can be affected by berberine and this effect depend on its dose and time . This might be the mechanisms underlying berber- ine to improve insulin resistance.
