Objective To explore the medical characteristics of end of-life care in elderly inpatients for improving their quality life and distributing appropriately the end-of-life medical expenditure.Methods The historical cohort study was used to survey the characteristics of admission disease,diagnosis and treatment and hospitalization expenditure.The patients were divided into the elderly group (age 60 years and over,228 cases) and control group (age ＜60 years,156 cases).Results There was a statistically significant difference in the admission disease proportion between elderly group and control group (x2 =91.345,P ＜ 0.0001),but the malignant tumor proportion had no differences between the two groups (x2 =9.761,P=0.082); the operation proportion in elderly group (16 cases,7.0％) was lower than in control group (28 cases,17.9％) ; the hospital stay time was longer in elderly group (12.5 days) than in control group (5 days),and the salvage times of elderly group (3 times)was more than that of control group,but the usage of medical device had no differences between the two groups (x2 =0.029,P =0.864).The hospitalization expenditure,medicine expenditure,western medicine expenditure,traditional Chinese medicine expenditure,and medicine proportion were higher in elderly group (15356.0 yuan,6448.3 yuan,5070.0 yuan,895.5 yuan,40.2％,respectively) than in control group.Conclusions Most of the elderly patients with chronic diseases at the end of life have no indication of operation and rely on medicine to maintain life for a long time,and the end-of-life medical expenditure is higher.

Type 1 diabetes mellitus ( T1DM),arising through a complex interaction of immune,genetic and environmental factors,results from autoimmune destruction of insulin-producing β cells.In up to one third of patients the autoimmune attack is not limited to β cells,but expands into autoimmune polyendocrine syndromes(APS).APS are characterized by functional insufficiency of multiple endocrine organs due to an immunologically mediated destructive process.APS can commonly be divided into three types,including APS type Ⅰ,APS type Ⅱ and immune dysregulation,polyendocrinopathy,enteropathy,X-Linked syndrome (IPEX).Here,we discuss the susceptible factors,clinical manifestation,screening and treatment of APS,with the perspective of the clues they can offer to the pathogenesis and treatment of type 1 diabetes mellitus.

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.

OBJECTIVE To investigate the effect of furanodiene(FDE),a diterpene derived from the medicinal plant Zedoary,on apoptosis of human gastric cancer MGC-803 cells induced in vitro. METHODS MGC-803 cells were treated with FDE 46.29~740.74μmol·L-1 for 24,48 and 72 h,and the cell viability was detected with MTT assay. Cell morphology was observed by light microscopy and Hoechst33342 staining. Flow cytometry was used to detect cell apoptotic rate and cell cycle. Rh123 staining and fluorescence probe DCFH-DA were employed to detect the changes in mitochondrial membrane potential (MMP) and reactive oxygen species(ROS). RESULTS MTT Results showed that FDE 46.29-740.74μmol · L-1 exhibited significantly higher cytotoxicity to gastric cancer MGC-803 cells. IC50 for MGC-803 of 24,48 and 72 h treatment was 347.91,257.41 and 101.01μmol·L-1,respectively. Treatment with FDE 92.58-370.32μmol·L-1 for 24 h also caused significant morphological changes in MGC-803 cells. AnnexinⅤ-FITC/PI double staining showed that the apoptotic rate increased after FDE 92.58-370.32μmol·L-1 treatment for 24 h(P<0.05). FDE enabled MGC-803 cell cycle arrest in S phase. DCFH-DA staining showed that FDE resulted in an increase in intracellular ROS levels(P<0.05) when PDE concentration was 370.37μmol·L-1(P<0.05). MMP decreased after FDE treatment when PDE concen?tration was 370.37μmol·L-1(P<0.05). CONCLUSION FDE Possesses potent tumor selected toxicity and can induce apoptosis of MGC-803 cells through cell cycle arresting,which is related to inhibition of DNA biosynthesis.

Objective To investigate the possible pathogenesis of type 2 diabetes mellitus (T2DM) combined with Alzheimer's disease (AD). Methods Wistar rats were randomly divided into control, T2DM, AD and T2DM +AD groups. The blood glucose levels were assayed, and the behavior changes were tested by Morris water maze. The glycogen synthase kinase-3β (GSK-3β) and hyperphosphorylation of tau protein were detected by immunohistochemistry staining. Results Compared with the control rats, the learning and memory abilities were weakened significantly in the model rats (F=28. 65, P<0.001). The expression of GSK-3β was higher in T2DM + AD group (4319. 02±653. 24) than in AD group (304. 39 ± 175. 83), T2DM group (540.43 ± 558.49) and control group (315. 56 ± 91. 64, H=19. 335, all P<0. 01). The level of hyperphosphorylation of tau protein was significantly increased in T2DM + AD group (8583. 81 ± 2236. 11) and AD group (2799. 61±1070. 02) than in control group (252. 02 ± 58. 37) and T2DM group (287. 75 ± 192. 53, H=32. 950, P< 0.001). There was no significantly difference of hyperphosphorylation of tau between T2DM group and control group (H = 32. 950, P>0. 05). Conclusions The increasing of GSK-3β activity in T2DM may be caused by hyperphosphorylation of tau.
