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.

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-s mol/L) and bFGF( 10-9 mol/L) + PD098059 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 I0-l0 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 PD098059, theinhibitor 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.

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 To understand the status and difference of breastfeeding behavior in urban and rural areas of Southwest China.Methods From March to July in 2011,3659 infants aged 6-24 months were selected by stratified cluster randomized sampling method in urban and rural areas of three provinces of Southwest China (Sichuan,Yunnan and Guizhou),including 1801 (49.2％)infants from urban areas and 1858(50.8％) from rural areas.Basic information of these infants,their families and breastfeeding was obtained by a questionnaire for the mothers or baby-carers.Descriptive analysis and survival analysis (Kaplan-Meier method) were used to describe breastfeeding behavior.Chi-square test and Log-Rank test were used to identify the differences of breastfeeding behavior between urban and rural areas.Results Early breastfeeding initiation rate within one hour after birth was 10.7％(355/3315),and the numbers of urban and rural areas were 12.3％(198/1604) and 9.2％ (157/1711),respectively,x2 =8.691,P＜0.05.Totally,20.3％(725/3575) of all infants were initially fed by breast milk after delivery,and 25.1％ (440/1754) in urban areas and 15.7 ％ (285/1821) in rural areas,x2 =49.192,P＜0.05.The exclusive breastfeeding rate and breastfeeding rate within four months after birth were 35.5％ (27.4％ in urban and 43.6％ in rural areas,x2=88.678,P＜0.05)and 76.2％ (68.5％ in urban and 84.3％ in rural areas,x2 =124.702,P＜0.05),respectively.However,the exclusive breastfeeding rate and breastfeeding rate within six months after birth reduced to 11.3％ (7.9％ in urban and 14.4％ in rural areas,x22 =18.001,P＜0.05) and 65.0％ (54.0％ in urban and 76.3％ in rural areas,x2 =199.662,P＜0.05),respectively.The median breastfeeding duration was 8.0 months (7.0 months in urban and 9.0 months in rural areas,x2 =96.780,P＜ 0.05).The most common reason of weaning was insufficient breast milk which accounting for 48.7 ％ of families [56.9％ (1161/2385) in urban and 39.9％(462/1157) in rural areas,x2=68.840,P＜0.05].Conclusions In Southwest China,intervention program should be implemented to improve the breastfeeding status.Breastfeeding behaviors are different between urban and rural areas in Southwest China.The initiation of breastfeeding in urban area is better,but the sustainability of breastfeeding is better in rural area.

OBJECTIVETo study retrospectively the clinical efficacy on pediatric recurrent pneumonia treated with point application in summer for the prevention in winter, as well as the relationship of age, sick duration, attack frequency and skin reaction with the clinical efficacy.

METHODSOne hundred and thirty-five cases of pediatric recurrent pneumonia were divided into a one-year group, a two-year group and a three-year group, 45 cases in each one according to the duration of treatment. The acupoints for the application were Dingchuan (EX-B1), Feishu (BL 13), Gaohuang (BL 43) and Danzhong (CV 17) with the same herbal plaster (prepared with rhizome corydalis, semen brassicae, euphorbia kansui and asarum sieboldii at the ratio of 2:2:1:1) on the first day of each of the three periods of the hot season, 2 to 4 h in each treatment. The attack frequency and change rate were observed before and after treatment in the three groups. The clinical efficacy was assessed in the three groups.

RESULTS(1) After treatment, the attack frequency of pediatric pneumonia was reduced apparently in the three groups (all P < 0.01). The result in the three-year group was less than that in the one-year group and the two-year group and the change rate was the highest (all P < 0.01). (2) After treatment, the sick duration was shortened apparently in the three groups (P < 0.05, P < 0.01). The result in the three-year group was the most remarkable, statistically and significantly different as compared with the other two groups (both P < 0.01). (3) The total effective rate in the three-year group was better than that in either of the other two groups [84.4% (35/45) vs 51.1% (23/45, P < 0.01), 84.4% (35/45) vs 71.1% (32/45, P < 0.05)]. (4) The total effective rate in the children aged from 4 to 7 years was better than that in the group aged from 8 to 10 years and the group aged from 11 to 14 years [79. 7% (47/59) vs 71.7% (33/46, P < 0.05); 79.7% (47/59) vs 43.3% (13/30, P < 0.01)]. (5) The total effective rate in the children with the sick duration ≥ 4 year was lower than that in the group with the sick duration <2 years and that 2 to 4 years (both P < 0. 01). (6) The total effective rate in the children with the annual attack frequency of 2 to 4 times was better than that with the frequency ≥ 4 times (P < 0.01). (7) For the cases with skin reaction after treatment, the total effective rate was better than that in the cases without reaction (P < 0.05).

CONCLUSIONThe point application in summer for the prevention in winter reduces the attack frequency of pediatric pneumonia, shortens the sick duration and has achieved the better significant efficacy in the cases of lower age, shorter sick duration, less attack frequency and moderate skin reaction.
