With high incident of cancer and chronic disease, it is more and more important to develop palliative care; as developing later, there is neither unified palliative care mode and related policy, nor mature assessment collaboration in China. It pointed out that Australia as an advanced country with stable development of palliative care and assessment collaboration, called palliative care outcomes collaboration (PCOC). It expatiated the PCOC on structure,function and operation. China should learn from the mode of Australia palliative care assessment and management collaboration, find references to improve and further develop Chinese palliative care assessment collaboration.

Objective To evaluate the effects of hydrogen-rich saline on the early diabetic neuropathic pain (DPN) in rats.Methods Healthy male Sprague-Dawley rats,aged 8 weeks,weighing 180-220 g,were used in the study.DPN model was made by intraperitoneal injection of 1％ streptozocin (STZ) 65 mg/kg.Twelve diabetic rats were randomly divided into 2 groups (n =6 each) using a random number table:DPN group and hydrogen-rich saline group (HRS group).Another 6 normal rats were randomly collected as control group (group C).At 14 days after STZ injection,hydrogen-rich saline 5 ml/kg was injected intraperitoneally once a day for 14 consecutive days in HRS group,while C and DNP groups received the equal volume of normal saline.Mechanical paw withdrawal threshold to yon Frey stimuli (MWT) and paw withdrawal latency to nociceptive thermal stimulation (TWL) were measured at 2 days before STZ injection (To) and 7,14,21 and 28 days after STZ injection (T1-4).The motor nerve conduction velocity (MNCV) of the right hindlimb and distal motor latency was measured after pain threshold was measured at T4.After measurement of neurological function was completed,tumor necrosis factor-α (TNF-α) and i nterleukin-6 (IL-6) contents (by ELISA) and nuclear factor kappa B (NF-κB) activity (by immuno-histochemistry) were detected.Results Compared with group C,MNCV was significantly decreased,the motor latency was prolonged,MWT was decreased at T1-T4,TWL was shortened at T2-T4,TNF-a and IL-6 contents were increased,and NF-κB activity was enhanced in DNP and HRS groups (P ＜ 0.05).Compared with group DNP,MNCV was significandy increased,the motor latency was shortened,MWT was increased at T3.4,TWL was prolonged at T4,TNF-a and IL-6 contents were decreased,and NF-κB activity was weakened in group HRS (P ＜ 0.05).Conclusion Hydrogen-rich saline can relieve the early DPN through inhibiting NF-κB signaling pathway in rats.

This study is to investigate the protein and mRNA expressions of pro-inflammatory and anti-inflammatory cytokines in U937 foam cells and effects of Ginkgo biloba extract (GbE) on the cytokines.U937 cells were cultured with different concentrations of GbE (0.1,1,and 10 μg·L-1),and stimulated by 100 mg·L-1 oxidized low density lipoprotein (ox-LDL) for 24 h.The expressions of interleukin-1β (IL-1β),tumor necrosis factor-α (TNF-α) and interleukin-10 (IL-10) in culture solution were detected by enzyme-linked immunosorbant assay (ELISA) and reverse transcriptase polymerase chain reaction (RT-PCR).The results showed that incubated with 100 mg·L-1 ox-LDL for 24 h,the U937 cells became foam cells,the protein or mRNA expressions of IL-1β,TNF-α,IL-10,and its receptor IL-10R in U937 foam cells were higher markedly than those in normal U937 cells.When the cells were pretreated with GbE (0.1,1,and 10 μg·L-1),the increases of IL-1β and TNF-α in U937 foam cells were remarkably inhibited,but IL-10 expression increased greatly.Especially when cells were pretreated with 10 μg·L-1 GbE,the protein and mRNA expressions of IL-1β and TNF-α were markedly lower than those in U937 foam cells.The protein expression of IL-10 and mRNA expressions of IL-10 and its receptor IL-10R were markedly higher than those in U937 foam cells.GbE inhibited production of pro-inflammatory cytokines IL-1β and TNF-α,but up-regulated the production of anti-inflammatory cytokine IL-10 and its receptor IL-10R in U937 foam cells,which might be related with its anti-atherosclerotic actions.

Objective To compare the effects of desflurane and sevoflurane on somatosensory evoked potentials (SEP) in patients undergoing spine neurosurgery. Methods Thirty patients with ASA grades I-Ⅱand undergoing spinal deformity orthopaedic surgery were selected and divided into two groups: desflurane group and sevoflurane group (n=30) . Bispectral index (BIS),the state of muscle relaxation, SEP and hemodynamics were monitored during operation. By maintaining the BIS in the range of 35-45,the state of muscle relaxation disappeared and hemodynamic became stable. Adjust the concentration of anesthetic step by step from 0 to 0.3, 0.6 and 0.9 maximum alveolar concentrations (MAC), then inhaled different concentrations of drugs. Record the incubation period and amplitude of SEP before inhaling anesthetics (based on the value), in the moment of achieving each inhaled concentration ( T1, T2 and T3) , and the moment that the inhaled anesthetics blows completely (regression value) . The percentages of T1, T2, T3, and the regression value compared with basic value were calculated.Results Compared with the basic value, T1, T2 and T3 of left arm, left leg and right leg in desflurane group, T2 and T3 of right arm in desflurane group, T2 and T3 of left arm, left leg and right arm in sevoflurane group,and T2 and T3 of right leg in sevoflurane group showed incubation period delaying ( <0.05) . And the incubation period extended along with the increase of inhaled anesthetics dosage. Compared with the basic value,T1,T2 and T1 of left arm and left leg in desflurane group,T1 of right arm in desflurane group, T1 and T2 of right leg in desflurane, T3 of left arm in sevoflurane group, T1 and T3 in left leg in sevoflurane group had decreased amplitude ( < 0.05), especially T1. Compared with desflurane, sevoflurane showed a weaker inhibition effect on the incubation period and amplitude of T1,T2,T3 of left arm and left leg,T2 and T3 of right arm and right leg, and the amplitude of T1 of right leg ( < 0.05) . Conclusion Both of desflurane and sevoflurane have inhibition effect on SEP. The inhibition effect gradually strengthens along with the increasing of dose. The inhibition effect of desflurane is stronger than sevoflurane.

Objective To isolate and culture human adipose-derived stem cells (hADSCs),investigate the influence of hADSCs on the cellular morphology,survival rate,and function of human islet cells under the in vitro non-contact co-culture conditions,and explore its mechanism.Method hADSCs were isolated by collagenase digestion method,then cultured,and identified by morphology,immunofluorescence and multi-directional differentiation.Adult islet cells were separated and purified by Liberase enzyme and Ficoll 400,then divided into co-culture group and individual group.The cellular growth morphology of islet cells was observed by inverted phase contrast microscope.The survival rate of islet cells,insulin secretory volume,insulin stimulation index and concentration of growth factor in the supernatant were compared between the two groups.Result hADSCs of the third generation showed uniform long spindle fibrocyte-like morphology,and had multi-directional differentiational potentials of osteogenesis and adipogenesis.Immunofluorescence test of surface antigens on hADSCs revealed CD44 + and CD49d +,CD31-,CD34-and CD106-.After 14-day culture,the islet cellular morphology in co-culture group was more intact than that in individual group.The survival rate of islet cells in co-culture group was (82.83 + 2.32) ％,and that in individual group was (53.00 + 2.82) ％ (P＜0.01).Insulin secretory volumes were (23.66 + 2.11) and (7.82 +1.09) mU/L respectively in co-culture group and individual group under high glucose concentration,and 13.22 + 0.77 and 6.40 + 0.44 mU/L respectively under low glucose concentration (P＜0.01 for all).Insulin stimulation index was decreased from 1.67 + 0.10 (at 3rd day) to 1.77 + 0.13 (at 14th day) in co-culture group,and from (1.67 + 0.10) (at 3rd day) to (1.77 + 0.13) (at 14th day) in individual group (P＜0.01).After 14-day culture,the concentrations of HGF,TGF-β,VEGF and bFGF in the supernatant were higher in co-culture group than in individual group (P＜0.01).Conclusion hADSCs were isolated and cultured successfully from adult adipose tissue.They could increase the survival rate and improve the function of islet cells when co-culture with the adult islet cells in vitro through secreting HGF,TGF-β,VEGF and b-FGF.
