Objective:To explore the relationship between friendship quality and loneliness and its influent factors like the measuring tool of friendship quality,the participants groups and cultural background. Methods:The studies on the association between the friendship quality and loneliness were collected through the databases of Chi-na National Knowledge Infrastructure,Wan Fang,Wiley Online library,Web of Science,Google Scholar and Duxiu from 1984 to 2014. Meta-analysis was conducted with the use of the CMA2. 0. Estimated value (r)and their 95%confidence interval (95%CI)was calculated to analyze the association between the friendship quality and loneliness from normal subjects except physiological disease (such as autism,etc. ). Results:Totally 46 literatures were met the requirements of meta-analysis with sample size of 19422,including 24 researches With 11846 participants who were from eastern countries,and 22 studies with 7676 western people. There was significant negative correlation of friendship quality and loneliness (r=-0. 28,95%CI:-0. 23--0. 32). The friendship quality measuring tool was able to adjust the relations of friendship quality and loneliness (Q=11. 95,P<0. 01). The participants groups had a regulatory role on the relationship between the friendship quality and loneliness (Q=19. 54,P<0. 001). Under dif-ferent cultural background of the subjects,the relationship between their friendship quality and loneliness was notsignificant difference (Q=0. 05 ,P>0. 05 ). Conclusion:It suggests that friendship quality has an influence on lone-liness. Measuring tools and subjects groups effect the relationship friendship quality and loneliness except cultural background.

Purpose To investigate the responsiveness of intracellular oxygen free radical and calcium on acrolein exposure and acrolein-induced cardiomyocytes apoptosis. Methods The viable adult mice cardiac myocytes were isolated by modified langendorff methods. We have examined the intracellular oxygen free radical and calcium concentration using DCF and Fura-2 AM, and the cardiomyocytes viability with WST assay. Are evaluated the DNA ladder pattern and cell apoptotic morphology on the adult mice cardiomyocytes that are exposed to acrolein. Results Our results show that acrolein can increase markedly the intracellular oxygen free radical and calcium concentration, that reach 12 fold and twofold respectively compared to the resting value when the cells were exposed to 1 μmol/L of acrolein. Moreover, the injury induced by acrolein in cardiac myocytes is concentration-dependent. The cardiomyocytes viability treated with 25, 50, 100 μmol/L of acrolein respectively were significantly lower compared to controls (P ＜ 0.01 ). DNA ladder pattern and apoptotic morphological changes were found after being exposed to acrolein in the adult mice cardiomyocytes. Conclusion It is concluded that acrolein induces adult mice cardiomyocytes apoptosis, and it may be due to the increased intracellular oxygen free radicals and calcium concentration.

Objective To study the pathological foundations of enhanced MRI with superaramagnetic iron oxide(SPIO) and its diagnostic value in liver diseases.Methods 52 SD rats were divided into 2 groups in random,group A(n=40) bred with 2 ‰ diethylnitrosamine(DEN) to induce hepatocellular carcinoma(HCC),group B(n=12) as control group bred with water.6 rats and 2 rats in group A and group B were killed 6,8,11,14,17,20 week later,respectively,before that every SD rats underwent conventional plain and SPIO enhanced MRI examinations.All specimens were examined by HE staining and immunohistochemistry to test CD 68 with SP.Results The successful ratio of induced HCC was 90% and the mortality was 15%.The rats in group A could be divided into 4 stages,including hepatic fibrosis(HF),liver cirrhosis(LC),hyperplastic nodules and hepatocellular carcinoma(HCC).CD 68 positive cell in the normal control tissue(22.83?4.61/HP) was significantly more than that in LC(11.67?4.64/HP)(P

Objective To investigate the normal anatomy and variation of Willis circle by 64-slice volume CT digital subtraction angiography(VCTDSA).Methods VCTDSA data of 174 patients with cephalocervical and cephalic scanning in our hospital from February 2006 to September 2008 were analyzed.Developmental condition,shape,size,integrity,and perforating branches of Willis circle were observed.Results(1) Hypoplasia was displayed in any component vessels of Willis circle.Incidence rate of hypoplasia was 20.1% in left posterior communicating artery,16.1% in right posterior communicating artery,13.8% in right anterior cerebral artery A1,9.2% in right posterior cerebral artery P1,7.3% in anterior communicating artery,6.3% in left posterior cerebral artery P1,and 3.4% in left anterior cerebral artery A1.Congenital arterial absence occurred more frequently in right posterior communicating artery(54.6%),left posterior communicating artery(52.3%),and anterior communicating artery(15.8%).(2) Hypoplasia or congenital absence of posterior circulation and anterior-posterior circulation occurred with a rate of 55.8% and 29.8% respectively.Integrity of Willis circle was only 9.2%.There were 17 perforating branches and 26 heubner inversion arteries observed in 174 Willis circle,with an average diameter of 0.82 mm and 0.94 mm respectively.Conclusion VCTDSA can display Willis circle completely and clearly.Using three-dimensional rotation may detect all kinds of variation and perforating branches of Willis circle.

ObjectiveTo explore the correlation between the prevalence of benign prostatic hyperplasia(BPH) and metabolic syndrome (MS)in the army elderly.Methods Totally 1 230 veterans (aged 70 years and over) from 26 military sanatorium in Shijiazhuang city were studied.The prevalence of BPH and MS was calculated.ResultsThe prevalence of BPH among the elderly was 77.0％.There was a trend of increase in the prevalence of BPH with increasing age (x2 = 50.4,P＜0.01).The prevalence of MS among the male elderly was 19.6％.MS was a risk factor for BPH(x2 =24.2,P＜0.0001).ConclusionsMS may be one of risk factors for the prevalence of BPH.

Objective To study if β-elemene can increase radiation-induced deoxyribonucleic acid (DNA) damage and decrease the damage repair.Methods Exponentially growing human lung adenocarcinoma cells (A549) were exposed to 10 or 20 μg/ml β-elemene for 24 h before irradiation.The effect of β-elemene on the in vitro radiosensitivity of A549 cells was evaluated using clonogenic assay.DNA damage and repair were evaluated using comet assay.Results Exposure to β-elemene before irradiation increased the radiosensitivity of A549 cells.The SERD0 for 10 μg/ml and 20 μg/ml β-elemene was 1.55 and 1.64, respectively.The SERDq for 10 μg/ml and 20 μg/ml β-elemene was 1.43 and 1.75, respectively.Combined treatment, comparing to irradiation or β-elemene treatment alone, induced higher levels of DNA damage and slower rate of damage repair.A549 cells exposed to 20 μg/ml β-elemene followed by irradiation showed a higher levels of tail moment (TM) than those exposed to irradiation or β-elemene alone at 0 h,2 h,6 h and 24 h after irradiation.The TM of the three groups at 0 h,2 h,6 h and 24 h after irradiation was 7.16±2.61,0.95±0.65 and 1.81±1.23(F=231.24,P<0.01), 3.65±2.06,0.11±0.07 and 1.58±1.40(F=90.22,P<0.01), 2.09±0.83,0.1±0.05 and 0.45±0.25(F=238.44,P<0.01), 1.45±1.37,0.11±0.08 and 0.60±0.40(F=38.94,P<0.01), respectively. Conclusions β-elemene can enhance the radiosensitivity of A549 cells through the enhancement of DNA damage and the inhibition of DNA damage repair.

A total of 60 brain injury patients with cognitive impairment were randomly divided into electro-acupuncture,computer and combination groups (n =20 each).The electro-acupuncture group received electroacupuncture,computer group cognitive rehabilitation training with specialized equipment and combination group both regimens.The treatment lasted for 2 months.Before training,Loewenstein occupational therapy cognitive assessment (LOTCA) test was not statistically significant among all groups (P 8 0.05).After 1 month,the combination group scored higher than pre-training (P ＜ 0.05).After 2 months,the scores of all groups were higher than pre-training(P ＜ 0.05).After 1 and 2-month training,the combination group scored higher than the other two groups in aspects of consciousness,optomotor tissue,attention,thinking and aggregate score (P ＜ 0.05).However,the orientation scores of all groups changed insignificantly after 1-month training (P 8 0.05),the combination group scored higher than the other two groups in improved orientation after 2 months (P ＜ 0.05).

Objective To investigate the change and clinical significance of thyroid CT value in patients with Graves disease and Hashimoto' s thyroiditis (HT).Methods One hundred and twelve Graves patients (GD group),54 HT patients (HT group) and 36 healthy people (NC group) were selected as our subjects.Computed tomography (CT) value of thyroid were measured.Results The CT value of the left thyroid gland was (70.53 ± 15.44) Hu in GD group,while (70.50 ± 16.01) Hu at the right side.In HT group,the CT value of the left thyroid gland was (53.77 ± 4.88) Hu,and (52.38 ± 6.67) Hu at the right side.The CT value of the left and right sides was (99.66 ±9.80) Hu and (100.77 ± 10.66) Hu in the NC group respectively.The CT value of GD and HT group were lower than that of the NC group (P ＜ 0.01),and the CT value of the HT group lower than that of the GD group more significant (P ＜ 0.01).Conclusion (1) The CT value of the GD group and the HT group are significantly lower than the NC group and the CT value of the HT group reduces more apparently than that of the GD group.(2) CT values can be used as an early,non-invasive diagnosis of GD and HT secondary indexes.
