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 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.

The concentration of 5 nucleosides, uracil, uridine, guanidine, adenine and adenosine in culture of Paecilomyces hepialid was determined by the developed method of HPLC. The HPLC method was performed on a Waters SunFire C18 (4.6 mm x 250 mm, 5 μm) column with methanol-water gradient elution as the mobile phase. The detection wavelength was 260 nm and the colunmn temperature was controlled at 30 °C. The linear range was 10.00-200.00 mg · L(-1) (r = 0.9994) for uracil, 10.10-202.00 mg · L(-1) (r = 0.9992) for uridine, 10.00-200.00 mg · L(-1) (r = 0.9991) for guanidine, 10.30-206.00 mg · L(-1) (r = 0.9992) for adenine and 10.45-209.00 mg · L(-1) (r = 0.9991) for adenosine, respectively. The RSD of precision was 0.032%, 0.035%, 0.039%, 0.049%, 0.00080%, respectively. The average recoveries of uracil, guanidine, adenine, and adenosine were 97.34%, 99.10%, 101.6%, 98.61% and 100.2% with RSD of 1.3%, 2.1%, 0.96%, 0.95%, and 1.3% respectively. The method showed high sensitivity, good selectivity, linearity and repeatability, which was suitable for the content analysis of 5 nucleosides components in P. hepialid and its extracts.

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.

Objective To explore the changes of the serurn cardiac enzymes in patients with acute massive pulmonary thromboembolosm(PIE),sub-massive PTE and non-massive FIE between pre-therapy and past-therapy and its relationship.Method The prospective multi-centres trial included 519 patients with confirmed PTE from 24 joint hospitals in Beijing,consisting of 54 massive FIE,195 sub-massive PTE and 270 non-massive PIE.Thrombolytic treatment was used in massive and sub-massive PTE patients with employment of urokinase and recombinant tissue plasminogen activator(rt-PA),and anti-coagulative therapy with unfractionated heparin and low molecular heparin was used in non-massive PTE.Results(1)The values of serum CPK and LDH in massive PTE patients before therapeutical intervention were obfiously higher than those in sub-massive and non-massive PTE patients(P<0.01);(2)Of 45 patients with high pulmonary pressure,24(54.4%)patients had high serum LDH(P<0.01).Of 169 patients with right ventrieular dysfunction,68(40.2%)ones has high serum LDH(P=0.049).Of 48 patients suffered from poor prognosis,15(30.8%)ones had high serum.LDH(P=0.039).Conclusions ①The vMues of serum CPK and LDH in acute PTE patients increase without elevation of CK-MB.②Serum LDH associates with pulmonary presure,right ventrieular function and prognosis.
