Chinese Journal of Practical Nursing 2014;30(18):16-19
Objective To investigate the intentions of pension mode of the aged in the unban and rural of Xi' an,and analyze the possible influential factors in old persons' choices of pension modes.Methods The purposive sampling method was used to survey the old persons about their pension intentions by questionnaire,and the collected information underwent statistical analysis.Results Among 317 old persons aged from 60to 91 years old investigated in the study,145 cases were from urban and 172 from rural area.Most old people intended to choose self-pension mode,family pension mode and community pension mode.Only few people chose institution pension mode.Their favorite pension mode was family pension mode,and institution pension mode was the last one to choose for old people.Community pension mode should be developed mostly in their opinion,and self-pension mode must be reduced.Some essential variables had significant influence on their choices of pension models,such as living in urban or rural,occupation,age,marriage,the incomes per month,family support,habitancy and so on.The result of logistic analysis showed that some other variables had no obvious influence on their pension intentions.Conclusions Old people in Xi'an prefer family pension mode mostly.Community pension mode is the one which has a good developing prospect.Social pension mode need to be intensified.

OBJECTIVE:To study antioxidant activities of ethanol extract of Paeonia lactiflora (CREt) and different polar parts in vitro. METHODS:CREt was prepared with 95% ethanol. CREt (extracted by 50% ethanal) was extracted with aether petrolei,acetic ether and n-butyl alcohol to obtain aether petrolei part (CRP part),acetic ether part (CRE part),n-butyl alcohol part(CRB part)and water part(CRW part). The ability of CREt and different polar parts eliminating DPPH·,O2-· and ·OH were investigated (mass concentrations of CREt and different polar parts were respectively 0.75-12,0.5-6,1.25-15 mg/ml in above 3 tests) and compared with ascorbic acid (VC,0.2 mg/ml) group. RESULTS:The maximum elimination rate of CREt to DPPH·, ·OH and O2-· were(97.55±0.25)%,(81.45±0.20)% and(75.28±0.41)%,IC50 were 1.629,1.789 and 5.268 mg/ml;those of CRE part to those radicals were (82.54 ± 0.36)%,(77.74 ± 0.42)% and (72.16 ± 0.73)%,IC50 were 2.481,1.918 and 6.005 mg/ml;that of CRB part to ·OH reached to(62.53±0.83)%,IC50 was 7.232 mg/ml,but to DPPH·、O2-· were less than 45%;those of CRP part and CRW part to those radicals were all lower than 40%. Each part could eliminate 3 radicals in dose-dependent manner,but were all poorer than VC group,with statistical significance (P<0.01). CONCLUSIONS:The CREt and CRE part show strongest antioxidant activities in vitro,and other parts have weak antioxidant effect.

Objective To evaluate the clinical efficiency and safety of thiazolidinediones (TZDs) on treat-ment of patients with nonalcoholic fatty liver disease (NAFLD). Methods The published controlled clinical trials about TZDs on treatment of patients with NAFLD from 1998 to 2008 were identified by searching in the full-text data base,such as Medline, PubMed, Ovid, EMCC, CBM Disc, CNKI, Wanfang, Weipu data and so on, as well as by searching of cross references from original articles and reviews. The enrollment standard was formulated strictly ac-cording to the designs of trials, and Meta analysis was performed by software package of Review Manage 4.2. Further-more, the statistic test, sensitivity and publication bias about the combined statistic data were revealed by referring to forest-graph and funnel-plot. Results All of the 473 patients in 18 controlled clinical trials were enrolled in this study. The weighted mean diffrerence of serum ALT, AST,TC,TG and BMI, HOMA-IR before and after treatment with TZDs 32. 24 (18.98-45.49) (Z=4.77,P<0.05),20.32 (2.30-38.35) (Z=2.21,P<0.05),0.26 (-0.01-0.54)(Z=1.88,P=0.06),0.63 (0.33-0.93) (Z=4.14,P<0.01),and -0.06 (-0.66-0.55) (Z=0.19, P=0.85),2.63 (1.33-3.93) (Z=3.96, P<0.01). In all papers, the improvement of hepatic tissue after treatment with TZDs in patients with NAFLD was observed in only 6 articles, which demonstrated the hepatic steatosis, inflammation and fibrosis [WMD (95% CI) 1.59 (1.08-2.10), 1.45 (0.90-2.00), 0.72 (0.12-1.32), Z= 6.08,5.16,2.33,P<0.05],especially the degree of NASH activity index,whose WMD (95% CI) was 4.21 (3.13-5.28) and Z=7.66,P<0.01, were improved significantly in the 104 NASH patients taken this kinds of drugs. There were 7 patients exiting from the all chnical trial, and the main adverse effects in patients accepting treat-ment with TZDs were debility, dizziness, edema of lower extremity, weight gain, indisposition of gastrointestinal tract, elevated liver enzyme and so on, which were similar to the control group. Conclusions The therapeutic effects of TZDs on NAFLD is confirmed. Not only are the serum liver enzyme,TC,TG and HOMA-IR in patients with NAFLD improved, but this new euglycemic agent has no acutely adverse effect in clinical application,which confirms the clin-ical efficiency and safety of TZDs on treatment of patients with NAFLD.

Objective To investigate the expression and significance of adiponectin(Adip) and the it's receptor 1, 2( AdipoR1, AdipoR2) in the pathogenesis of alcoholic liver disease ( ALD). Methods Fifty male Wistar rats were acclimatized for 7 days and then 10 rats were randomly assigned to be control. Others were to develop the rats mod-el of ALD by intragastric alcohol of increasing concentration and volume gradually [30% ~ 60%, 5 ~9 g/(kg · d)] , 8, 8, 8 and 9 rats were sacrificed randomly at the end of 4th, 8th, 12th and 16th week, liver samples and liver homogenate (10% ) were collected respectively. The concentration of triglyceride (TG) in the liver homogenate and the level of adiponectin and tumor necrosis alpha (TNFα) in the serum were measured by bi-ochemical chromatometry and ELISA method respectively. The mRNA and protein expression of Adip, AdipoRl and AdipoR2 in the hepatic tissue were performed by reverse transcription polymerase (RT-PCR) and Western blot. Results The model of rats alchoholic liver disease was developed. With the progress of ALD,the level of TG and TNFα in serum increased and the contention of Adip decreased gradually. The expression of Adip and AdipoR2 mRNA and protein decreased and no significant change was found in the AdipoRl. There is a negative correlationbetween the expression of serum Adip and AdipoR2 in hepatic tissue and the level of serum TNF-α and TG in the liver homogenate. ( r =-0. 98 ~-0. 90, P < 0. 01 ). The expression level of Adip protein was positively correlated with the contents of Adip in the serum ( r = 0. 90, P < 0. 01 ). Conclusion There is a close correlation between the decreased expression of Adip and AdipoR2 and adipose degenaration and inflammation in hepatic tissue.

Objective The mechanism and signaling mechanisms of fracture healing by vasoactive intestinal peptide (VIP) regulating are not clear.We established an selective cut off sensory/motor nerve combined with tibial fracture rat model to study the effects of VIP and microvessel density(MVD) during the fracture healing process after nerve injury.Methods 60 SD rats were randomly divided into 3 groups: tibial fracture + motor nerve (anterior root) cutting group (group ART);tibial fracture + posterior root (sensory nerve) cutting group (group PRT);tibial fracture group (group SO),and each group were 20.Three groups of rats in the model after the establishment of 1W, 2W, 3W, 4W these time points, were killed.The skeleton specimens were obtained in the vicinity of the fracture 5mm, to observe the expression of VIP and microvessel density of the law of change.Results Histology observation showed: new bone trabecular bone callus maturity of PRT group is lower than SO group and ART group at each time points;the immunohistochemical staining showed that compared with callus VIP average optical density of PRT group at 2w and 3w(0.156±0.015、0.163±0.012), SO group(0.216±0.012、0.223±0.010) and ART group(0.198±0.014、0.212±0.016) increased obviously(P<0.05).The detection of callus MVD indicated that compared with callus MVD average density of PRT group at 2w and 3w(26.4±2.2、32.3±2.0), SO group(38.2±2.3、40.6±2.6) and ART group(36.6±2.2、38.5±2.1) significant increased (P<0.05).At the 2nd, 3rd and 4th week, the wet weight of tibia was significantly increased in group ART and SO compared with group PRT(P<0.05),which increased more significantly at 2 weeks.Conclusion The effect of loss of sensory nerve innervation on the formation of microvessel density, callus maturity and fracture healing rate were more pronounced than loss of motor nerve innervation.
