ObjectiveTo observe the status of social supports of the patients with advanced cancer and probe the effective nursing measures to improve the social supports of the patients.Methods"Social support rating scale"of Xiao Shui-yuan was applied to investigate the social support state of a total of 58 advanced cancer patients and 63 patients with chronic diseases.ResultsThe total score of patients with advanced cancer was(32.86±6.86),of patients with chronic diseases was(41.83±7.88).Compared with chronic disease group,the patients with advanced cancer received less social supports(P<0.05).The marriage state and economic income were significant factors to influence social support.ConclusionsThe patients with advanced cancer received less social supports than patients with chronic disease.Nursing staff should evaluate the status of social supports correctly,provide health education on patients and members in the net of social supports,make use of relative resources,then improve the social support level of the patients.

After the contents and characteristics of SCI-covered papers list database in Dalian Medical University were described, it was pointed out that databases in academic library should provide more contents and links for the users to browse information and to use related resources by making full use of network technology. Technology and manpower should be well prepared and librarians should be qualified with patience and painstaking if an excellent SCI-covered papers list database is to be developed.

Objective To evaluate the clinical value of 64-slice spiral computed tomography combined with hs-CRP and MMP-9 to detect the vulnerable plaque of acute coronary syndrome.Methods Seventy-two patients with coronary heart disease were included and among them,43 patients were diagnosed as ACS and the other 29 patients diagnosed as stable angina group(SAP).All patients underwent 64-slice spiral computed tomography coronary artery imaging and examination of plasma hs-CRP and MMP-9 concentration.All patients underwent selective coronary angiography.Another 25 cases who underwent coronary angiography were included in the control group.Results The incidence of soft plaque was higher in the ACS group than in the SAP group(24 cases vs 4 cases,P=0.001).Compared with the control group,levels of hs-CRP and MMP-9 in the ACS group and the SAP group were both significantly higher(all P

Objective To evaluate the impact on long-term survival using elective transcatheter arterial chemoembolization (TACE) before liver transplantation (LT) to treat patients with hepatocellular carcinoma (HCC).Methods A medical literature search was conducted up to October 2011 to identify comparative studies which evaluated survival rates,recurrence rates,and disease free survival.Pooled odds ratios (OR) and 95 ％ confidence intervals (95 ％ CI) were calculated using either the fixed or random effect model.Results 571 patients were included into this meta-analysis:326 patients were treated with elective TACE before LT and 245 patients were not treated before LT.A comparison between the elective pretransplantation TACE group and the LT only group showed the odds risks (95％CI) of 1-,3-,5-years overall survival rate were 1.90 (0.09-3.33),1.19 (0.67-2.14),1.23(0.63-2.39),respectively.The odds risks (95％CI) of 1,3,5-years disease free survival rates were 1.36 (0.65-2.83),0.91 (0.48-1.75),1.16 (0.76-1.79),respectively.The odds risk (95％CI of recurrence was 1.60 (0.65-3.89).Conclusion Pretransplatation TACE improved 1-year overall survival,but it did not improve the 3 and 5 years overall survival,disease-free survival and recurrence rates.

The morphological and molecular identifications of Cyclospora-like oocysts of dogs were underwent in the present study, in which the morphological characteristics of the Cyclospora-like oocysts firstly found in the stool samples of dogs, such as shape, size, acid-fast staining,sporulation and auto-fluorescene, were observed. According to the published sequence of the rDNA gene of Cyclospora in GenBank, 3 primers were designed and were used to amplify part of the 18S rDNA gene of dog-associated Cyclospora-like organism by nested PCR.The amplicons were purified and cloned into vector pMD19T. Then, the positive clones screened were sequenced and subjected to sequence homology and phylogenetic analysis. It was found that the morphological charactertistics of the Cyclospora-like oocysts in dogs were similar to that of the human Cyclospoa oocysts and the size of-the amplified fragment of 18S rDNA was proved to be 715 bp, that was identical to that of the target fragment. Based on the results of sequence homology and phylogenetic analysis, the dog-associated Cyclospora-like organism was identified as the Cyclospora species.

BACKGROUND:Based on the integration of virtual reality technology with acupoints, acupuncture can be expressed three-dimensional y.
OBJECTIVE:To explore the structure of points through reconstructing digitalized three-dimensional visualization of Neiguan (PC6) structure based on VOXEL-MAN and Micro-XCT.
METHODS:Muscles and other tissues adjacent with Neiguan (PC6) were segmented and merged based on the VOXEL-MAN system combined with the anatomical knowledge of acupoints;nerves and blood vessels were performed with three-dimensional reconstruction;the needle-inserting animation of Neiguan (PC6) was obtained by running script file. Three-dimensional visualization and virtual needle-inserting researches of Neiguan (PC6) were performed. Nature of the acupoints was detected by the Micro-XCT-200 machine additional y.
RESULTS AND CONCLUSION:The visualization of the anatomical structure of local Neiguan (PC6) was completed, and the localization and expression of Neiguan (PC6) in the digitized virtual human were realized. The Neiguan (PC6) structure was researched with Micro-XCT-200, and showed there was no new tissue. Local three-dimensional reconstruction of the acupoint structure could help to display the anatomical structure of acupoints and simulate the acupuncture process. It could also help to observe the relationship between the needle body and the surrounding tissues during needle-inserting, which supplying a good basis not only for exploring the security of needle-inserting, but also for improving the clinical effect of acupuncture. The research on the structure of acupoint Neiguan (PC6) by Micro-XCT-200 provides further experimental evidence for the hypothesis of three-dimensional acupoint.
