Objective To evaluate the value of 18F-fluorodeoxyglucose (FDG) PET/CT in evaluation of curative effect and progression-free survival (PFS) for lymphoma patients.Methods The data of 85 lymphoma patients were retrospectively analyzed.Before and after 4-8 cycles standardized chemotherapy,the patients were evaluated with 18F-FDG PET/CT.The two-year PFS rate was compared.The value of 18F-FDG PET/CT in evaluation of curative effect and PFS for lymphoma patients received chemoradiotherapy was analyzed.Results The non Hodgkin lymphoma (NHL) was the common type,and the common pathogenic sites were head and neck lymph nodes,mediastinum and retroperitoneum.The majority of patients were accompanied with spleen enlargement and local lesions with high metabolism.The complete remission (CR) rate of Hodgkin lymphoma (HL)patients in PET/CT negative group was significantly higher than that in positive group (86.4％ vs.42.9％,P =0.038).The two-year PFS rates in PET/CT positive group and negative group were 42.9％ and 81.8％,and the difference was statistically significant (x2 =7.70,P =0.006).Thirty-five NHL patients achieved CR,13 achieved partial remission (PR),and 8 achieved stable disease (SD) or disease progression (PD).The two-year PFS rates in the CR group,PR group,SD or PD group were 89.7％,65.3％ and 19.4％ respectively,and the difference was statistically significant (x2 =12.41,P =0.002).PET/CT imaging had a strong PFS predictive effect on T cell lymphoma (TCL) patients (x2 =13.85,P =0.001) and diffuse large B cell lymphoma (DLBCL)patients (x2=13.51,P =0.001),and had no predictive effect on follicular lymphoma (FL) patients (x2 =4.63,P =0.099).Conclusion 18 F-FDG PET/CT can evaluate the curative effect of lymphoma effectively and early predict prognosis,and has great guiding significance in choosing therapeutic schedule.

Objective To identify the normal breast tissue and breast fibroadenoma tissue by shell-isolated nanoparticle-enhanced Raman spectroscopy (SHINERS),and to explore the biological characteristics of FD and the identification method by discussing its spectroscope characteristics.Methods The frozen section of 26 patients (all female,aged 19-59 years)were obtained by routine surgical resection.9 cases of normal tissue and 17 cases of breast fibroadenoma tissue were detected by Raman spectroscopy and then SHINERS technique was utilized.A total of 243 Raman and 273 SHINERS spectra were obtained.All the spectra were dealt with baseline corrected by fitting and subtracting a third-order polynomial and then smoothed with a 15-point Adjacent-Averaging.Results The characteristic peaks of normal breast tissue appeared in 1 090,1 157,1 262,1 300,1 442,1 658,1 745,and 1 874 cm-1 .After adding SHINs, some peaks shifted in 2 - 3 cm-1 , the relative strengths of 1 090 and 1 157 cm-1 were significantly increased,and the 1 496 cm-1 characteristic peak appeared.The main characteristic peaks of breast fibroadenoma appeared in 751,880,930,880,1 262,1 442,1 579,1 658,and 1 745 cm-1;one of the dominant characteristic peak should belong to lipids,but it can be seen that amideⅠ characteristic peak of protein became more significant.Conclusion Raman spectra can discover the differences of the characteristic peaks of amide Ⅰ between breast fibroadenoma and normal breast tissues. By virtue of different enhancement effects of SHINs to Raman specific peaks of the various tissues, breast fibroadenoma can be distinguished from normal tissue successfully.

BACKGROUND:Currently, there is stil no clear conclusion on the pros and cons of arthroscopic anterior cruciate ligament reconstruction with or without stump preservation residues as wel as the impact of reconstruction with stump preservation on proprioceptive sensation. OBJECTIVE:To compare the curative effect of arthroscopic anterior cruciate ligament reconstruction with or without stump preservation on the function and stability of the knee joint during a 1-year folow-up. METHODS: A retrospective analysis of 75 cases of arthroscopic anterior cruciate ligament reconstruction was done, including 37 cases of anterior cruciate ligament reconstruction without stump preservation and 38 cases of anterior cruciate ligament reconstruction with stump preservation. Autologous hamstring tendons were selected as implants. Evaluation of preoperative (6 months before operation) and postoperative (6 months and 1 year after operation) knee function and stability was implemented on the basis of Lysholm scores, IKDC Scores and KT2000. The comparative analysis was carried out as wel on repeated passive angle for proprioception testing. RESULTS AND CONCLUSION:Al of the patients were folowed up for 12 to 20 months. Range of motion of the knee joint was basicaly restored in the two groups 6 months after operation. The results showed the Lysholm scores, IKDC scores and KT-2000 scores at 6 months and 1 year after operation were significantly improved in the two groups as compared with the preoperative data (P < 0.05), and there was no statisticaly difference between the two groups. The proprioception difference between the healthy and affected sides was lower in the patients with stump preservation than those without stump preservation at 6 months and 1 year after operation (P< 0.05). There were two cases in each group whose bone tunnel of the tibia was found deviating from the ideal position through postoperative X-ray examination, but cyclopia was unseen. Anterior cruciate ligament reconstruction with stump preservation is beneficial to the recovery of postoperative proprioception without increasing of postoperative complications.

Objective To approach the evaluative effect of respiratory variation of superior vena cava peak flow velocity measured using transthoracic echocardiography (TTE) on fluid responsiveness in patients with mechanical ventilation.Methods A prospective cohort study was conducted.All mechanical ventilated critically ill patients whose fluid therapy was planned due to hypovolemia in Department of Critical Care Medicine of Beijing Tongren Hospital of Capital Medical University from April 2011 to April 2013 were enrolled.Volume expansion was performed with 500 mL Linger solution within 30 minutes.Patients were classified as responders if pulse pressure variation (PPV) increased ≥ 13％ before volume expansion.The respiratory variation in superior vena cava peak velocity was calculated as the difference between maximum and minimum values of velocity in peak A,peak S and peak D over a single respiratory circle,and their variations (ΔA,ΔS,ΔD) were also calculated.The receiver operating characteristic curve (ROC curve) was plotted to assess the evaluative effect of respiratory variation of superior vena cava peak velocity on fluid responsiveness.Results Twenty-seven patients were enrolled in this study.Volume expansion increased PPV ≥ 13％ happened in 14 patients (responders).The velocity of superior vena cava in peak A,peak S,peak D was significantly increased after volume expansion compared with that before volume expansion in responders [peak A (cm/s):34.6 ± 2.2 vs.31.3 ±2.1,t=-2.493,P=0.027; peak S (cm/s):39.1 ± 1.3 vs.35.3 ±2.1,t=-2.564,P=0.024; peak D (cm/s):28.1 ± 1.2 vs.23.3 ± 1.4,t=-4.995,P=0.000],but there was no significant difference in ΔA,ΔS and ΔD between before and after volume expansion.The ΔA,ΔS and ΔD were positively correlated with PPV (r＝0.040,P=0.854; r=0.350,P=0.074; r=0.749,P=0.000).The area under ROC curve (AUC) of peak S was 0.36 [95％ confidence interval (95％CI):0.11-0.52],but the AUC of ΔS was 0.68 (95％CI 0.47-0.89),the AUC of peak D was 0.41 (95％CI 0.19-0.63),but the AUC of ΔD was 0.95 (95％CI 0.86-1.00),so the aberration rate of superior vena cava in respiration was better than the flow rate in superior vena cava.When the cut-off value of ΔS was 20.7％ for predicting fluid responsiveness,the sensitivity was 78.6％ and the specificity was 61.5％.When the cut-off value of ΔD was 12.7％ for predicting fluid responsiveness,the sensitivity was 92.0％ and the specificity was 92.3％.Conclusion Respiratory variations in superior vena cava peak velocity measured by TTE could assess fluid responsiveness in patients with mechanical ventilation.

Objective To investigate the relevance ratio of abnormal electrocardiogram (ECG) and describe the abnormal ECG index among the residents in Keshan disease (KD) area.To assess the KD illness severity and provide comparable quantitative indicators,provide the scientific basis for elimination of KD.Methods Non probability sampling method was used,and monitoring stations with the highest incidence of KD at the county level were selected in 2012.Clinical examination and 12 lead ECG was carried out.According to The KD Diagnosis Standard (WS/T 210-2011),eight common changes in ECG of KD were scored.According to age and sex group,check the abnormal rate of ECG detection of Keshan disease,while analysed the changes of abnormal ECG index score in latent KD patients and chronic KD patients.Abnormal ECG index to determine:If there was one change,the score was 1 and the abnormal ECG index was 1.And so on,the highest score was 8.Results Totally 61 831 residents were surveyed and 9 634 were found with abnormal ECG,and the relevance ratio of abnormal ECG was 15.58％;totally 3 862 residents had eight ECG changes of KD and the relevance ratio was 6.25％;totally 508 residents were diagnosed with KD and the relevance ratio was 0.82％.The relevance ratio of abnormal ECG among all age groups was statistically different (x2 =3 065.64,P ＜ 0.05).The relevance ratio of abnormal ECG in women was higher than that of men [3.91％ (2 419/61 831) vs 2.33％ (1 443/61 831),x2 =86.30,P＜ 0.05].Abnormal ECG index score was (1.06 ± 0.25) which was not statistically different between gender [men:(1.07 ± 0.27) vs women:(1.06 ± 0.24),t =1.41,P ＞ 0.05].The abnormal ECG index score in latent KD patients was lower than that of chronic KD patients [(1.09 ± 0.30) vs (1.60 ± 0.69),t =-4.87,P ＜ 0.05].In eight ECG changes,the most check out items were T wave and/or ST segment changes (2 816).Conclusions The relevance ratio of abnormal ECG in KD area is at a higher level.The abnormal ECG index can be used to assess the KD illness severity and provide comparable quantitative indicators,in order to provide a new train of thought for the evaluation of KD elimination.

Objective To investigate the imaging characteristics of lymphoscintigraphy in postoperative breast cancer patients and evaluate its diagnostic value in breast cancer-related lymphedema (BCRL).Methods Seventy-nine breast cancer patients who underwent mastectomy and axillary lymph node dissection were studied. Patients ( n = 158 ) were divided into the study ( affected arms, n = 79 ) and control groups ( contralateral arms, n = 79). After subcutaneous injection of 99Tcm-dextran via the first interphalangeal space, lymphoscintigraphy was performed at 10 min, 1,3, 6 h respectively. Sensitivity and specificity of lymphoscintigraphy for detection of BCRL were calculated. Results There were significant differences in the amount of visualized lymph nodes, lymphatic integrity and backflow pattern between the two groups.Lymphatic drainage was preserved in 96.2% (76/79) of the contralateral arms and only 5.1% (4/79) of affected arms. 87.3% (69/79) and 74.7% (59/79) of control arms had ≥2 lymph nodes in axilla and supraclavicular regions, respectively; while none ( 0/79 ) and 5.1% (4/79) of the affected arms had ≥ 2lymph nodes in both regions, respectively. Four backflow patterns of radiotracer in subcutis were observed in the affected arms: normal (2.5% , 2/79), dilatated (55.7%, 44/79), diffused (36.7%, 29/79) and without backflow (5.1%, 4/79 ). The sensitivity and specificity of "lymphatic integrity" and "backflow pattern" on lymphoscintigraphy for detecting BCRL were 97.5% (77/79) and 96.2% (76/79), 94.8%(73/77) and 100.0% (81/81), respectively. Conclusion Lymphoscintigraphy is a noninvasive, accurate and effective imaging modality for the evaluation of BCRL.

Objective To investigate the topographic distributions of dopamine transporter (DAT),dopamine D2 receptor and glucose in Parkinson's disease (PD) and multiple system atrophy (MSA) using positron emission tomography/computed tomography (PET/CT) scanning and statistical parametric mapping (SPM) analysis.Methods Seventy subjects (39 PD patients,15 MSA patients and 16 normal controls) who came from People's Liberation Army General Hospital from September 2013 to November 2015 underwent DAT,D2 receptor and glucose brain PET/CT scans using 11 C-methyl-N-2-β-carbomethoxy-3-β-(4-fluorophenyl) tropane (11C-β-CFT),11C-raclopride and 18F-fluorodeoxyglucose (18 F-FDG) as radiotracers,respectively.The uptake patterns were analyzed using SPM software.Results Striatal DAT binding decreased in the putamen in PD patients compared with controls (Z =5.21-5.77,P =0.002-0.016).D2 receptor showed no significant differences.However,glucose uptake decreased in cingulate gyrus(Z =4.51-4.67,P =0.010-0.017).For MSA patients,both DAT and D2 receptor binding decreased in the putamen(Z =2.13-3.42,P =0.000-0.016).Glucose uptake decreased in the bilateral putamen,cerebellum and part of frontal temporal lobes (Z =1.86-3.75,P =0.000-0.032).Conclusion Multiple modalities PET/CT scans using the ligands 11 C-β-CFT,11C-raclopride,and 18F-FDG are valuable in diagnosis of MSA and differential diagnosis of MSA from PD.
