In order to service clinical departments, reduce the cost and improve the efficiency of the storage, on the basis of information system, the overall planning of the requirement of frameworks and internal infrastructures of the hospital logistics center are proposed. The requirements of supplier admittance, the quality and the activities of the storage, the storage ratio of materials and the storage expense are discussed. It is pointed out that the integration management of logistics center, access control items, the reasonable management of storage materials, analyzing, evaluating and adjusting of various management indicators are effective methods of product quality assurance, reducing storage losses and monitoring costs.

Objective To investigate how internet using (both time and activities)and effortful control would contribute to the sex difference of problematic internet use (PIU).Methods A total of 844 adolescents aged 9-20 years old were selected from Chinese Academy of Sciences twin-sample by simple random sampling,with boys accounting for 45.6％ and girls accounting for 54.4％.The internet using and effortful control were measured using self-report questionnaires in the first time(T1),the problematic internet use were measured after one and half years (T2).The difference and relation of Internet using,effortful control and problematic internet use between boys and girls were measured with Chi-square test,t test and correlation analysis.The moderating effect of sex between internet using and PIU were explored by utilizing regression analysis.The mediation effect of effortful control between sex and PIU were explored with Sobel test.Results The anverage internet time of working day and weekend in boys were 1.52 h and 2.12 h respectively.The average internet time of working day and weekend in girls were 1.49 b and 2.05 h respectively.Significant difference between boys and girls is not existed in the internet time (t=0.541,0.907,P＞0.05).And the boy was inclined to game(x2 =47.669,P＜0.01).The effortful control of boys and girls were 54.09 and 55.76 respectively.The score of boys' and girls' PIU were 22.48 and 20.72 respectively.Boys' effortful control was significantly lower than that of girls (t=-2.879,P＜0.01).The score of boys' PIU was significantly higher than that of girls' (t=3.612,P＜0.01).Adolescents' PIU were significantly correlated with the time,entertainment and social activities (r=0.249,0.175,0.140,P＜0.01).The moderating effect of sex was significant in the relation between internet time and PIU.Significant mediation effect of effortful control existed in the PIU difference between boys and girls(Z=-2.54,P＜0.05).Conclusion Significant mediation effect of effortful control exists in gender and PIU.

Electroencephalogram(EEG) is necessary in diagnosis of status epilepticus (SE),particularly in non-convulsive SE with minor or atypical clinical manifestations.SE is a dynamic process,as seizures continue,in which EEG changed and appeared nonepileptic rhythm discharges.Ictal EEG patterns of SE are non-specific and different types of SE have different EEG features.In this paper,the EEG of different type SE will be summarized.

Objective To assess the effect of arterial embolization in treating hyperthroidism by colour ultrasonography.Methods Forty two cases of hyperthyroidism were treated with thyroid arteries embolization. A few days before and 1, 3, 6 months after embolization, the echograms of thyroids were observed including the volumes of thyroids and the internal diameters of thyroid arteries were measured with colour ultrasonography respectively. The Vs, Vd, Vm, PI, RI were measured with the Doppler and the quantities of blood flow were calculated. The relationships of changes for all these parameters and T 3, T 4 and TSH were analysed. Results Before artery embolization all thyroids were enlarged with diffusely homogenous or heterogenous low echos and nodules in some patients accompanied by widenings of the thyroid arteries and their branches full of blood supply. The volume of thyroids decreased after artery embolization. 1 3 months later the echo of thyroids enhanced and got coarse with decrease of the thyroid vasculature and narrowing of vessel calibers except a few star or spot like blood streams were sometimes seen within the thyroids and no blood flow signals found in some cases. 3 6 months after embolization, the echo of thyroids decreased gradually or unevenly distribnted. All the parameters of blood flow before and after the treatment showed statistically significant differences( P

Objective To observe the changes of STAT3 signaling transduction pathway and autophagy activity in human glomerular mesangial cells cultured in high glucose, as well as the effect of STAT3 on autophagy, exploring whether SAT3 further influence extracellular matrix proteins type IV collagen secretion through the regulation of autophagy. Methods Culture human renal mesangial cells under different conditions, STAT3 pathway was inhibited with specific blocking agent S3I?201 and siRNA respectively. The experiment was divided into: (1) Control group: normal glucose concentration; (2) High glucose group: divided into 12 h, 24 h, 48 h, 72 h incubation group. (3) High glucose+S3I?201 group: pretreated cells with 30 μmol/L S3I?201 (Selleck S1155) for 1 h, then incubation with high glucose for another 24 hours. (4) High glucose+STAT3?siRNA group: siRNA transfection firstly, then incubation with high glucose for 24 hours. (5) High glucose+S3I?201+3?MA group: pretreated cells with 2 mmol/L 3?MA (Selleck S2767) and 30 μmol/L S3I?201 for 1 h, then incubation with high glucose for another 24 hours. Western blot was employed to detect the protein of STAT3, p?STAT3 and autophagy related protein LC3, p62 expressions. The changes of autophagosome quantity was observed with transmission electron microscope. The extracellular matrix protein collagen IV expression was measured with ELISA. Results Compared with the control group, glomerular mesangial cells cultured with high glucose for 24h, the expressions of STAT3 and p?STAT3 increased (P<0.01), while the expression of autophagy related proteins LC3II/LC3I decreased. The expression of p62 increased and the number of autophagosome reduced under transmission electron microscope, which all indicated the decrease of autophagy activity (P<0.05). Blocking STAT3 signaling pathway with S3I?201 and STAT3?siRNA respectively, compared with high glucose group, LC3II/LC3I was up?regulated and p62 was down?regulated, and the number of autophagosome was increased significantly, which all indicated the increase of autophagy activity (P<0.05). Extracellular matrix proteins collagen IV expression of cells cultured with high glucose was higher than the control group (P<0.05), and the application of S3I?201 blocking STAT3 pathway caused type IV collagen expression to decrease (P<0.05). The application of the autophagy inhibitor 3?MA could convert the result and lead to an increase of type IV collagen expression (P<0.01). Conclusions High glucose could active STAT3 signaling pathway of human renal mesangial cell and increase STAT3, p?STAT3 expression. High glucose could inhibit autophagy activity of human renal mesangial cells. Inhibition of STAT3 pathway activation may reduce the inhibitory effect of high glucose on autophagy of human renal mesangial cells. High glucose leads to an increase of type IV collagen secretion of human glomerular mesangial cells. The activation of STAT3 pathway may increase type IV collagen secretion through negative regulation of autophagy, which eventually leads to diabetic nephropathy.
