With the development of the human society, people have come to pay more and more attention not only to their life quality but also to the quality of their life before death. Hence the emergence of hospice. At present there are three types of hospice in China: the family type, the general hospital type, and the special institution type. Each of these types has its own shortcomings. Hence the need for social work to intervene in hospice. The paper discusses the viability and necessity of the intervention through the notion, channels and methods of intervention. The role of social workers in hospice is also discussed.

Objective To explore the effect of microRNA‐21(miR‐21) on the migration and invasion ability in human laryn‐geal squamous carcinoma cell Hep2 .Methods The MTT method was used to detect the viability of Hep2 cells at 48 h after miR‐21 inhibitor and miR‐21 NC transferring into Hep2 cells by LipofectamineTM 2000 .The cell migration ability was detected by using the scratch test .The cell invasion ability was detected by using the Transwell method .The activation of phosphatase and tensin homo‐logue deleted on chromosome 10 (PTEN)/phosphatidylinositol 3 kinase (PI3K) /protein kinase B(Akt) signal pathway and the expression of matrix metalloproteinase 2 (MMP2) ,MMP9 ,reversion inducing cysteine rich protein with kazal motif (RECK) was detected by using the Western blotting .Results Compared with miR‐21 NC ,miR‐21 inhibitor could significantly reduce the Hep2 cellviability[(0.688±0.043)vs.(0.375±0.012)],inhibitedthemigrationability[(6.57±0.02)μm vs.(20.49±2.18)μm]and invasion ability[(100 .7 ± 10 .2) vs .(46 .8 ± 4 .3)] ,and the differences were statistically significant (P<0 .01) ,meanwhile miR‐21 inhibitor could down‐regulate the expression of PI3K ,MMP2 and MMP9(P<0 .01) ,and reduced the phosphorylation level of Akt (P<0 .01) ,up‐regulated the expression of PTEN and RECK (P<0 .01) .Conclusion miR‐21 inhibitor can significantly suppress the migration and invasion ability of Hep2 ,which may be related with the PTEN/PI3K/Akt signal pathway .

ABSTRACT:Objective To investigate the regulation of adenovirus type 36 infection on precursor protein particles progranulin expression in Uygur obese patients.Methods Based on the diagnostic criteria of obesity,the samples were divided into obese group and non-obese group.Serum neutralization test was used to detect the antibody of Ad36.The progranulin mRNA expressions in abdominal omental and subcutaneous adipose tissues were detected by real-time quantitative PCR.ELISA method was used to determine serum progranulin protein levels. CD68 protein expression of macrophage was detected by immunohistochemistry. Results ① In the Uygur population of our study,compared with that in the non-obese group (38/1 1 7,32.5%),the number of obese patients (54/1 1 5,47.0%)infected with Ad36 was significantly higher than that in non-obese group (P <0.05 ).② Serum progranulin was significantly increased in the Ad36-infected obese group (408.45±1 56.92)than in non-obese group (326.1 1±1 58.60)(P <0.05).The mRNA expression of progranulin did not differ between the two groups.③ The macrophage infiltration was significantly higher in the Ad36-infected obese group (14 730.1 6 ± 2 227.39 )than in non-obese group (10 786.50 ± 2 772.80 )(P < 0.05 ).Conclusion Ad36 infection may be associated with the occurrence of obesity in Uygur population,and adenovirus type 36 infection may regulate the expression of serum progranulin at the protein level.

Objective To investigate the effects of high-flux hemodialysis (HFD) on fibroblast growth factor-23 (FGF-23) levels in maintenance hemodialysis (MHD) patients and its clinical significance.Methods Sixty uremia patients were divided into HFD group and hemodialysis (HD)group and observed for 12 months.Flow mediated dilation (FMD),cardiac ultrasonography,levels of FGF-23,serum phosphorus,serum calcium,25-(OH)D3,parathyroid hormone (PTH),homocysteine (Hcy) and interleukin-6 (IL-6) were tested in all patients before and after treatment.The correlation of above indexes were analyzed.Results No statistical difference were found in primary disease,age and duration of dialysis in two groups.The levels of FGF-23 [(56.07±26.63) vs (85.53±40.54) ng/L,P ＜0.01],IL-6 [(3.37±2.48) vs (5.59±2.53) ng/L,P ＜ 0.05] and Hcy [(21.13±6.95) vs (29.40±11.66) μmol/L,P ＜ 0.05] decreased and FMD,25-(OH)D3 [(27.3± 10.26) vs (23.15± 10.73) μg/L,P ＜ 0.05] increased significantly after the treatment of HFD.There were no significant changes in the HD group.The baseline FMD was negatively correlated with FGF-23 (r =-0.413,P ＜ 0.05) and Hcy (r =-0.301,P ＜0.05).The baseline LVMI was correlated with FGF-23 (r =0.464 P ＜ 0.05).After one year's trearmeat of HFD,the changes of FMD(/△ FMD) was negatively correlated with the changes of FGF-23 (/△ FGF-23)(r =-0.347,P ＜ 0.05).Conclusions HFD can improve FMD and decrease FGF-23 levels.The improvement of FMD may be related to the decreased level of FGF-23.The effect of FGF-23 on FMD should be independent of serum phosphate.

Objective To figure out the preliminary clinical value of real-time three-dimensional echocardiography(RT-3DE) in evaluating the systolic dyssynchrony in patients with coronary artery heart disease(CAD).Methods Eighty patients who were suspected as CAD were included in this study.RT-3DE was performed first.After the analysis,we got the data:ejection fraction (EF),16 segments systolic dyssynchronic index (SDI 16).All subjects should take the coronary angiography.According to coronary angiography results,the patients with the vascular stenosis rate ≥50% were defined as the CAD group,and the patients with the vascular stenosis rate <50% were defined as the coronary atherosclerosis group,the patients with the completely normal angiographic results were included in the control group according to the results of angiography.The parametric differences among the groups were compared.Results There was no significant difference in LVEF among the three groups.SDI 16 had no significant difference between the control group and the coronary atherosclerosis group (t=-1.03,P>0.05).However,SDI 16 had significant difference between the control group[(3.72±2.68)%]and the CAD group[(7.14±3.10)%],the same between coronary atherosclerosis group[(5.12±3.46)%]and the CAD group[(7.14±3.10)%](t=-3.71,-2.34,all P<0.05).ROC curve analysis revealed that a cut-off value for SDI of 5.49%,yielded a sensitivity of 81.8%,with a specificity of 73.1% to predict coronary atherosclerosis to CAD(AUC=0.743).Conclusion SDI 16 >5.49% has a higher value in evaluating systolic dyssynchrony in patients with CAD with RT-3D of Siemens Acuson SC2000 ultrasonic diagnostic instrument.

Allergic rhinitis and rhinosinusitis often complicate with asthma,and their relationship has long been investigated.From the view of epidemiology,all of these three diseases have higher prevalence,complicate with each other,are risk factors and prognostic factors for each other.Besides,they share common in anatomy and pathophysiology.In this paper,the interrelationship among allergic rhinitis,rhinosinusitis and asthma in pathogenesis is discussed.

Objective To investigate expression of glutathione S-transferase(GST) mRNA in peripheral blood of the population in coal-burning fluorosis area and to evaluate the effect of comprehensive control intervention. Methods Fifty samples of peripheral blood from patients in the coal-buring fluorosis area in Bijie county of Guizhou province were selected as fluorasis group and 50 samples of peripheral blood from patients in area with comprehensive management were selected as intervention group, respectively. Fifty samples from non-endemic fluorosis area were selected as the control group. Total RNA from blood was extracted and purified by the Trizol- Phenol-Chloroform one-step method. Expression of GST mRNA was detected by using SYBR Green I real-time fluorescence quantitative PCR. Results The data of GST mRNA in fluorosis group, intervention group and control group was 38.28±27.22,70.56±37.23 and 103.46 ± 46.62, respectively. There was a significant difference between the groups(F = 3.75, P < 0.05). Decreased expression of GST mRNA in fluorosis group and intervention group as compare to control was detected(all P < 0.05), and the expression of GST mRNA in intervention group was higher than that in fluorosis group(P < 0.05). Conclusion Coal-burning fluorosis possibly led to the decreased expression of GST mRNA in peripheral blood, and comprehensive control maybe prevent the decreased expression of GST in mRNA level.
