The clinical application of GlucoWatch used in 32 Chinese diabetic patients was evaluated to determine its value in following blood glucose trends and track patterns and to know the compliance of patient. The results confirmed the accuracy of GlucoWatch and showed that it could follow blood glucose trends and track patterns. The skin irritation was mild and most subjects thought that blood glucose monitoring by GlucoWatch could reduce the pain caused by traditional methods.

OBJECTIVE To explore risk factors of cervical lymph node metastasis in cN0 papillary thyroid carcinoma. METHODS The clinical data of 537 patients with cN0 papillary thyroid carcinoma were analyzed retrospectively in Beijing Tongren hospital from Jan 2009 to Dec 2015. Patients' gender, age, multifocal lesion, carcinoma complicated with Hashimoto's thyroiditis, capsule breakthrough and tumor size were counted. RESULTS The lymph node metastasis rate of 537 patients with cN0 papillary thyroid carcinoma was 30.9%(166/537). The incidences of lymph node involvement were 24.95%(166/537) at only level VI, 5.21%(28/537) at level VI plus lateral part of neck and 0.74%(4/537) at only skip metastasis, respectively. Chi square test and multivariate logistic regression analysis showed that cervical lymph node metastasis was statistically associated with male, age<45 years, capsule breakthrough and tumor diameter>1 cm (P<0.05). After the operation, there were 17 patients with temporary hoarseness, accompanied with 1 loss to follow-up and 1 failure to return to normal after 1.5 years. There were 61 patients with temporary hypocalcemia, 2 patients failed to follow-up and 2 patients with calcium supplements after respective 1.5 and 4 years. CONCLUSION To stratify the risk of patients with cN0 papillary thyroid carcinoma, male, age<45 years, capsule breakthrough and tumor diameter>1 cm are risk factors for cervical lymph node metastasis. And we suggest that prophylactic central lymph node dissection may be appropriate.

Objective The aim of this study was to observe the outcome and evaluate the clinical efficacy of pulsed electromagnetic fields (PEMF) on pain management in patients with osteoporosis.MethodsA total of 58 patients with osteoporosis were treated with PEMF stimulation.Pains as main indicators of their symptom were evaluated before and after treatments.The clinical outcomes were assessed by observing the visual analogue scale (VAS).Statistical analysis was carried out to support the data.Results After PEMF treatment,the patients exhibited significant pain relief from mean VAS of 6.97±1.83 to 3.36±1.69(t-test,P＜0.05 ).Of the 58 patients,28 obtained significant symptom alleviation and 18 obtained moderate symptom alleviation,while 8 obtained slight alleviation,indicating the total clinical efficacy of 93%(54/58).Conclusion The current study provides the clinical outcomes indicating that PEMF may help to release the pain from primary osteoporosis and it might be an applicable supplementary treatment method for the osteoporosis related pain.

AIM: To observe whether metallothionein plays a role in cardiac protective effect of basic fibroblast growth factor on anoxic/reperfusion (A/R) injury in cultured cardiomyocytes and study the possible mechanism of cardiac protection by bFGF.METHODS: The present study made the model of myocyte A/R injury after having a 24 h incubation by bFGF(10 -10、10 -9、10 -8 mol/L) and bFGF(10 -9 mol/L)+PD 098059 respectively. We measured the levels of MT and MDA in myocytes, and the changes of LDH and protein in cultured medium. We also counted the number of viable cell in groups.RESULTS: The contents of myocardial MT were significantly increased after treatment by bFGF. The levels of MT in 10 -10 mol/L、10 -9 mol/L and 10 -8 mol/L bFGF treated groups increased 54%\, 62%\, 76% respectively, compared with the A/R group, and the number of viable cell were also greatly increased, LDH and protein leakage in cultured medium and MDA contents in myocyte were dramatically decreased in bFGF treated groups. All the protection were completely disappeared with the inhibition of MT production with PD 098059, the inhibitor of mitogen-activated protein kinase(MAPK).CONCLUSION: MT involves in the protection of bFGF in cultured cardiomyocytes. It might be related with activation of MAPKase.

AIM: To elucidate the cellular source of adrenomedullin (AM) in myocardial tissue, the effects of 5 substances on secretion of AM from cultured rat fibroblasts and myocytes were examined in this study. METHODS: Myocardial fibroblast and myocyte isolation and culture; AM was measured by radioimmunoassay; AM receptors were assayed by radioactive analysis method. RESULTS:Tumor necrosis factor ? (TNF?), lipopolysaccharide (LPS) and basic fibroblast growth factor (bFGF) all could stimulate AM synthesis and secretion in myocardial Fb and myocyte , and the amount of AM secreted by Fb was greater than that by myocytes, whereas transforming growth factor-?(TGF?),and interferon-?(IFN?) suppressed in it in myocardial Fb and myocytes. Myocardial Fb has two kinds of AM binding sites, but myocyte has only one high affinity- binding site.CONCLUSIOIN:Myocardial fibroblasts could synthesize and secrete AM, and there are AM receptors in both myocardial fibroblasts and myocytes.
