In recent years, because the wearable medical devices can indicate the health monitoring index of blood sugar, blood pressure, heart rate, oxygen content, temperature, respiration of the human body anytime and anywhere, can also be used for the treatment of various diseases, accompanied by the development of large data, which will bring a subversive revolution for the medical device industry. This paper introduces the development of wearable devices, key technical index of main products, and to make a preliminary study on its quantity control.

Objective To assess the value of intheleukin-6 (IL-6) in early diagnosis of children with acute lower respiratory tract bacterium infection . Methods Serum IL-6 levels of 85 children with acute lower respiratory tract infection were detected by ELISA and c-reactive protein (CRP), white blood cells (WBC), ploymorphonuclear (PMN) were measured in acute phase. Results When indices above were judged independently ,the reliability of IL-6 was highest with its sensitivity, specificity, positive predictive value (PPv), negative predictive value (NPV) and Youden’s index being 84% ,94% ,93% ,87% and 0.78 respectively .While united tests were used , diagnosis accuracy of IL-6 combining CRP was superior to classical indices (CRP,WBC,PMN). Conclusions The combination of IL-6 and CRP seems to be a valuable parameter in the early diagnosis of children with acute lower respiratory tract bacterium infection .

Objective To study the route of branches of the internal iliac artery for presenting basic applied anatomy to be used in pelvic tumor diagnosis and interventional therapy through angiographic manifestations. Methods The branches of the internal iliac artery were studied by means of dissection on 45 adult cadavers(30 male, 12 female), including the origin, length, external diameter and bifurcation angle; and additionally angiographic characteristics of pelvic tumors in 42 cases together with normal ones of another 50 cases through bilateral selective internal iliac arteriography. Results①The angle between left and right common iliac artery was (58.9??7.3?),and that between the external and internal iliac artery was (27.6??5.3?). Iliolumbar artery and obturator artery were mainly originated from the main trunk of internal iliac artery and the distal portion (50%, 84.8%).②The external diameter of the branches of the internal iliac artery measured on cadavers was significantly smaller than that on patients alive. Conclusions Normal variations occur frequently in the origination, site of orifice and route of the middle and small branches of the internal iliac artery.

AIM: This study is designed to demonstrate the drug resistance breast cancer cell line MCF-7/ADM has a higher proportion of cancer stem cells than its original parent cell line MCF-7 in vitro.METHODS: Firstly,the drug resistance of MCF-7/ADM was estimated by MTT method,and then higher proportion of cancer stem cells in MCF-7/ADM than that in MCF-7 was demonstrated by three aspects: side population analysis,sphere culture and cell surface markers of breast cancer stem cells.RESULTS: The drug resistance index of MCF-7/ADM compared to MCF-7 was 37.1.The proportion of side population in MCF-7/ADM and MCF-7 was 9.60%?0.66% versus 0.39%?0.11%;The proportion of sphere-initiating cells in MCF-7/ADM and MCF-7 was 10.27%?0.64% versus 1.03%?0.15%,and the proportion of CD+44CD-24 cells in these two cell lines was 64.87%?3.87% versus 3.70%?0.53%,all are statistically significant.CONCLUSION: ADM resistance breast cancer cell line MCF-7/ADM has a higher proportion of cancer stem cells than that in its original cell line MCF-7.

Objective To investigate clinical characteristics and risk factors in elderly patients with type 2 diabetes mellitus (T2DM) complicated with chronic kidney disease (CKD).Methods Two hundred and two T2DM patients aged ≥60 y admitted in Tongren Hospital from August 2009 to February 2012 were enrolled in the study,including 64 cases complicated with CKD (CKD group)and 138 cases without CKD (non-CKD group).Hemoglobin (Hgb),albumin (ALB),glycated hemoglobin A1C (HbA1 c),fasting plasma glucose(FBG),postprandial glucose (PBG),serum creatinine (Scr),blood urea nitrogen (BUN),uric acid (UA),total cholesterol (TC),triglyceride (TG),high densitylipoprotein (HDL-C),low density lipoprotein (LDL-C) were measured and ratio of urinary albumin to creatinine (UAER/CR) were calculated,ankle brachial index (ABI) and ambulatory blood pressure was examined.Results The duration of diabetes in CKD group was longer than that in non-CKD group [(13 ± 11) vs.(10 ± 7) y,t =2.35,P ＜ 0.05].Hgb and ALB in CKD group were lower than those in non-CKD group [(12.1 ± 1.7) vs.(13.3 ±1.3) g/L,(34.4±2.6) vs.(36.8 ±3.4) g/L,t=-5.73,-4.75,allP＜0.01]; UA,TG,24 h systolic blood pressure (SBP),24 h pulse pressure (PP)in CKD group were higher than those in non-CKD group [(367 ± 81) vs.(323 ± 74) μmol/L,(1.6 ± 0.9) vs.(1.3 ± 0.7) mmol/L,(133 ± 14) vs.(127±16)mmHg,(65 ±12) vs.(58 ±12)mmHg,t =3.82,2.50,2.47,3.68,all P＜0.1].The UAER/CR in CKD group and non-CKD group was 86.2 mg/g (24.6-374.8 mg/g) and 6.0 mg/g (3.6-17.8 mg/g),respectively (P ＜ 0.01) and ABI in CKD group and non-CKD group was 0.94 ± 0.18 and 1.03 ±0.18 (-2.78,P ＜0.05).There were no significant differences in FBG,PBG,HbA1c,TC,HDL-C andLDL-C between two groups(t =-2.02,1.47,1.48,-0.53,-1.20,-0.76,all P＞0.05).Logistic regression analysis showed that ALB,TG and UAER/CR were the independent risk factors of CKD in T2DM patients(OR:0.79,3.63 and 1.04,95％ CI:0.62-1.01,1.45-9.01 and 1.00-1.08).Spearman correlation analysis demonstrated that eGFR was positively associated with Hgb,ALB,ABI (r =0.38,0.33 and 0.28,all P ＜ 0.01),negatively associated with age,BUN,Cr,UA,TG,UAER/CR,24 hSBP and PP in all diabetes patients(r =-0.32,-0.63,-0.89,-0.34,-0.18,-0.65,-0.16 and -0.248,all P ＜0.01).Conclusions ALB,TG,UAER/CR are the independent risk factors of chronic kidney disease in elderly patients with type 2 diabetes mellitus.

Methods:According to WSB 64-2003 verification regulation for cardiac defibrillators and cardiac defibrillator-Monitors, and the practical experience of effective detection methods, defibrillation analyzer verification can be used to detect the performance parameters of cardiac defibrillators. Results:In accordance with the effective test method, through regular check, not only can cardiac defibrillators risk be eliminated but also quality safety of clinical use and the life safety of patients will be safeguarded. Conclusion:The quality control can prevent medical accidents that caused by facility loses, at the same time, if we are pay attention to the daily maintenance, the defibrillator can be played a role in emergency time.

Objective To investigate the relationship of PTEN,Ki-67,type of credits of thymoma in WHO organization and Masaoka staging,and the significance of the biology's expression in thymoma.Methods The expression of PTEN and Ki-67 in 52 pieces of thymoma specimens was detected by the method of immunohistochemical SP.Results Positive expression rate of the 52 patients with thymoma was decreased gradually after WHO classification (8/10,10/14,6/12,4/11,0,0 and 10/13,12/20,6/16,0),Masaoka staging and PTEN.The difference were significant in statistics (λ2 =11.751,P =0.038 ; x2 =8.311,P =0.040).Positive expression rate of Ki-67 was gradually increased (1/10,6/14,6/12,8/11,2/3,2/2 and 3/13,9/20,10/16,3/3),the difference was also significant in statistics (x2 =11.231,P =0.047; x2 =7.904,P =0.048).Conclusions The positive expression rate of PTEN,Ki-67 are both related to clinical classification and staging closely.The detection to the positive expression rate of PTEN and Ki-67 can contribute to judging thymoma biological characteristics,thus,it will be helpful in diagnosing the thymoma,analyzing the degree of malignancy,invading and transferring ability.And then provide objective indicators for clinical diagnosis and treatment.
