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 different methods on the diagnosis of white coat and masked phenomena in ambulatory blood pressure monitoring (ABPM). Methods • Information of clinical characteristics and laboratory data were collected, and measurements of office blood pressure (OBP) and ambulatory blood pressure (ABP) in 274 subjects were performed, including 46 persons with high normal OBP (SBP/DBP 130-139/85-89 mmHg) (1 mmHg=0.133 kPa), 187 untreated patients with grade 1 and grade 2 hypertension (SBP/DBP 140-179/90-109 mmHg), and 41 treated hypertensive patients. Differences of 95th and 5th percentile between OBP and daytime ABP, were respectively taken as the cutoff for the definition of white coat phenomenon and masked phenomenon. Results • If white coat and masked phenomenon were diagnosed according to the current hypertension guidelines, the prevalence of white coat phenomenon did not differ between untreated and treated hypertensive patients (11.2% vs 7.3%, P=0.460). In the untreated group, the prevalence of white coat phenomenon was higher in grade 2 than in grade 1 hypertension (20.0% vs 8.5%, P=0.033), whereas the prevalence of white coat hypertension did not differ (2.2% vs 7.0%, P=0.230). The prevalence of masked hypertension was 73.9% in high normal blood pressure group. The prevalence of masked uncontrolled hypertension was 4.9%. If the difference of 95th percentile (≥20.50/20.50 mmHg) and 5th percentile (≤-18.67/-6.00 mmHg) between OBP and daytime ABP were, respectively, used as the cutoff for the definition of white coat and masked phenomenon, the prevalence of white coat phenomenon did not differ between treated and untreated groups (12.2% vs 9.1%，P=0.543). In the untreated group, the prevalence of white coat phenomenon was higher in grade 2 than in grade 1 hypertension (24.4% vs 4.2%, P=0.000). The prevalence of masked phenomenon did not differ between persons with high normal OBP (15.2%) and untreated (5.9%) as well as treated hypertensive patients (12.2%) (P>0.05). Conclusion • The percentile methods may be useful for the diagnosis of white coat and masked phenomena.

Objective: To evaluate the efficacy and safety of a long-term adding metformin to a basic treatment strategy in systemic lupus erythematosus (SLE), and analyze whether the beneficial effects of metformin add-on treatment during the open-label proof-of-concept trial persisted during a posttrial follow-up (the metabolic memory effect), as there is a paucity of systematically collected data concerning long-term metformin use in SLE. Methods: Subjects who had participated in the open-label proof-of-concept trial and gave informed consent to this study were enrolled, and the disease flares and long-term adverse effects between metformin group and control group were compared. In addition, whether the benefit regarding decreased disease flare persisted after metformin withdrawal during the post-trial follow-up was investigated. Results: Twenty-nine subjects in the former metformin add-on strategy group and 28 subjects in the former control group were enrolled. No adverse reactions of metformin occurred during the study. The risk of disease flare in the control group was higher than that in the continuous metformin group, but the difference was not statistically significant (P=0.326). After metformin withdrawal, the risk of disease flare in the metformin group gradually increased to the control group (P=0.998). There was no significant difference between the two continuous metformin use groups whose metformin using duration are 2.56 years and 5.00 years respectively (P=0.802). Conclusion: A long-term metformin add-on treatment is security, and can keep SLE patients in a lower risk of disease flare. The metabolic regulation of metformin in SLE immune disorder may present a time-dependent metabolic memory effect.
