ObjectiveTo explore the efficacy of 131 Ⅰ treatment in Graves' disease,and to analyze the related factors.MethodIn 87 patients with Graves' disease,thyroid uptake ratio( TUR ) and its effective half-life(EHL) were compared before and after 131 Ⅰ treatment.The weight of thyroid gland was evaluated with radio-imaging and type B ultrasonography.ResultThe dose of 131 Ⅰ was ( 185.2 ± 148.0 ) MBq.The TUR of tracer dose and therapeutic 131 Ⅰ dose were 76.5 % ±8.2% and 73.3 % ±9.0% ( t =2.451,P =0.008 ).The EHL were ( 5.2±0.7 ) and ( 5.0 ±0.8 )days,respectively ( t =1.998,P =0.023 ).After followe-up of ( 57.0 ±26.3 ) months,49 patients ( 56.3 % ) became euthyroid,14 ( 16.1% )manifested delayed hypothyroidism,and 24 (27.6%)remained in hyperthyroidism.Thyroid autoantibodies were found in 34.5% patients,of whom,the incidence of hypothyroidism was higher in patients with positive autoantibodies than those with negative ones (30.0% vs 8.8%,x2 =6.560,P =0.009 ).ConclusionBoth TUR and EHL of therapeutic doses of 131 Ⅰ are lower than the tracer doses.Positive thyroid autoantibodies may affect the outcome of the 131 Ⅰ treatment.

Objective To investigate the effect of curcumin an extract of a Chinese medical herb on the sensitivity of CD133 + rectal cancer cells to radiotherapy.Methods In vitro experiments:CD133 +cells were purified with immunomagnetic beads from HRT-18 cell line and divided into curcumin group,radiotherapy group and curcumin plus radiotherapy group.MTT assay and Annexin V/PI staining were used to measure the proliferation and apoptosis of the cells.In vivo experiments:Transplanted rectal tumor was established in 46 nude mice and randomly divided into curcumin group,radiotherapy group and curcumin plus radiotherapy group.Tumor size and apoptosis were detected by daily observation and TUNEL staining respectively.Results Curcumin inhibited proliferation and apoptosis of CD133 + rectal cancer cells when combined with radiotherapy.It also significantly increased the growth inhibition of rectal tumor and promoted the apoptosis of rectal cancer in vivo.MTT assay showed that after 24 hours,compared with that of radiotherapy group(14.6% ± 1.0%),curcumin plus radiotherapy group (18.7% ± 1.7%) inhibited the growth of the tumor(P < 0.01).Annexin V/PI showed that curcumin plus radiotherapy group (28.8% ±3.7%) was significantly different from the radiotherapy group(13.1% ± 1.4%) in cell apoptosis (P <0.01).In vivo,after 6 days,tumor volume (521 ± 79) mm3 in curcumin plus radiotherapy group was significantly lower than that of radiotherapy group(717 ± 134) mm3 (P < 0.01) ; TUNEL staining results indicated that the RCST in curcumin plus radiotherapy group (26.1% ± 3.3%) were higher than that in radiotherapy group (12.0% ± 2.1%) (P < 0.01).Conclusions Curcumin significantly enhances the radiosensitizing effect for CD133 + rectal cancer cells.

Objective To evaluate the value of increased threshold of SUVmax and delayed imaging on diluted and filled bladder for improving the detection of bladder cancer with 18F-FDG PET/CT.Methods From July 2007 to October 2012,18 F-FDG PET/CT was performed on 63 suspected or treated (with bladder preserved) bladder cancer patients (55 males,8 females,average age 69.1 years).After routine imaging,all patients were given 1 500-2 000 ml of water orally three times and voided three times.Then they underwent delayed pelvic imaging at a full bladder status.The routine images were reanalyzed with increased SUVmax threshold (from 6-8 to 8-20).The final diagnosis was confirmed by pathology or follow-up (>6 months).The differences of SUVmax in urine,18 F-FDG metabolism in lesions between routine and delayed imaging were compared.Paired t test was used to compare their differences.Results The SUVmax of urine on routine and delayed imaging was 15.11±11.11 and 4.73±2.00 respectively (t=4.15,P<0.01).Among the 63 patients,there were 15 malignant and 3 benign cases confirmed by pathology,and 45 patients without obvious abnormality during follow-up.All 18 cases were detected by 18F-FDG PET/CT including the 3 benign false positive cases (2 were positive by CT though negative by PET,and 1 FDG-avid cystitis).All 15 true positive cases were confirmed as primary or recurrent bladder carcinoma and 1 false positive case as inflammation.The detection rates of early imaging with routine and increased display threshold of SUVmax were 18.8%(3/16) and 43.8%(7/16),respectively.Conclusion Increased SUVmax threshold for display and delayed imaging with diluted urine under full bladder status could effectively improve the detection rate of primary or recurrent bladder cancer with 18F-FDG PET/CT.

BACKGROUND:Skeletal muscle satelite cels are muscle-derived stem cels with proliferation and differentiation potential distributing between the muscle cel membrane and the base film. Studies have shown that skeletal muscle satelite cels are of efficacy and safety, but the survival rate of the transplanted stem cels is very low, which greatly limits the application of skeletal muscle satelite cels. OBJECTIVE: To observe the effects of Fasudil on apoptosis of skeletal muscle satelite cels induced by H2O2. METHODS: Skeletal muscle satelite cels cultured in vitro were randomly divided into three groups including H2O2group, H2O2+Fasudil group (Fasudil group) and control group. Apoptosis rates were observed by flow cytometry. The concentrations of interleukin-4 and tumor necrosis factor-a in each group were detected by ELISA. Western blot was employed to measure the protein level of Bax in each group. RESULTS AND CONCLUSION: Compared with the H2O2group, a significant decrease was found in the apoptosis rate of cels, protein level of Bax, and concentrations of interleukin-4 and tumor necrosis factor-a in the Fasudil group (alP < 0.05). These findings indicate that Fasudil can play anti-apoptosis protection by inhibiting Rho-kinase signaling pathway, which may be related to the reduced expression of Bax.

Objective To develop a real-time QRS complex detection algorithm of dynamic ECG signals for the GPRS mobile telemonitoring system. Methods Before the first and second derivatives of ambulatory ECG signals were processed by moving average method, the signals sampled from CM5 monitoring lead were filtered with the average of continuous four ECG sample signal points. The R waves could be detected precisely by local minima of second derivatives and Q & S waves were located correctly by cross-zero points of first derivatives of ambulatory ECG signals in a short-time searching windows. The QRS recognition thresholds, which could revise themselves according to the detected values and vary with the analyzing signals, were designed in this paper. Results With a polynomial computation complexity, the novel algorithm insensitive to baseline draft and noise caused by mobile communication filtered power-line interference and most of muscle noise and reduced the search time below 0.02 s during detecting each Q wave, R wave and S wave. For the normal and clinical patients, this algorithm correctly detected up to 99.8% of the QRS complex of ambulatory ECG signals. Conclusion The algorithm can meet the need of real-time QRS complex detection and analysis for the GRRS mobile ECG telemonitoring system.

This study was conducted to examiune the fibrotic effect of Ni-Ti and 317L al loys in esophagus.The extract fluid from Ni-Ti,317L alloys was made according t o the ASTM standards of U.S.A. The Fb of esophageal scar was cultured primarily ,then incubated with alloy abstract fluid. The proliferating activity of Fb was measured by MTT at 4, 24, 48, 72 hours in the course of culturing. The esophagu s embedding test of Ni-Ti,317L alloys was made according to ASTM standards of U .S.A.The tissue around the alloys was taken at weeks 2 and 12,and the pathologi c changes were analysed. The results showed that Ni-Ti,317L extract could depre ss the proliferating function of Fb gently,and the depressing action increased gradually with the culturing time.The result of embedding test was in accord wit h the ASTM standards of U.S.A completely; the fibrotic membrane around the NiTi, 317L alloys became thinner with embedding time. These findings suggested that t he scattering composition of Ni-Ti,317L in body fluid might not activate the pr oliferating and secreting function of Fb,and the two alloys could not lead to f ibrosis of esophagus aroun them.
