Objective To investigate the features of patients with cyclic citrullinated peptide (CCP) antibodies in primary Sj(o)gren's syndrome (pSS) with the retrospective method.Methods Seventy eight pSS patients were studied.Enzyme-linked immunosorbent assay (ELISA) indirect immunofluorescence was used to measure anti-CCP antibodies.The patients with and without anti-CCP antibodies were correspondingly classified as autoantibody-positive and negative pSS groups.Clinical and laboratory features were compared between autoantibody-negative and positive group.Results (1) Seven (9.0％) of pSS patients had positive anti-CCP antibody.No significant difference was found in sex,ages,and disease course between autoantibody-nagative and positive pSS patients.(2) The anti-CCP-positive pSS was associated with the rates of decayed tooth,fatigue,dry mouth,dry eyes,and tender of joint (P ＜ 0.05).Whereas,the antiCCP-negative pSS was not significantly related to fever and mumps (P ＞ 0.05).(3)From serologic characteristics aspects,the anti-CCP-positive patients showed higher level of tender of joint than the anti-CCP-negative patients.No significant difference was found in white blood cell (WBC),hemoglobin (HGB),platelet (PLT),erythrocyte sedimentation rate (ESR),C-reactive protein (CRP),immunoglobulin A (IgA),IgG,IgM,and rheumatoid factor (RF) between two groups (P ＞ 0.05).Conclusions The anti-CCP-positive patients were 9％ ofpSS patients,and were more likely to occur tender of joint with higher level of tender of joint.

Objective To investigate couple's personality similarity effect on the marital quality,and to explore the vairance of such effect under different levels of spouse's depression. Methods The cross?sectional da?ta of 4644 couple from the national survey of mental health database in china( 2009) was used. Couples completed Locke ?Wallance marital adjustment test,The CES?D scale a self?report depression scale and Eysenck personality questionnaire short scale for Chinese version (EPQ?RSC). Results The personality similarities of couples(0.44 ±0.27) and their marital quality (wife (103.71±27.54),husband (106.15±26.94))had significant positive corre?lation ( r=0.25~0.27, P<0.01). Regression analysis showed the effect of personality similarity on the marital quality were varied according to the level of spouse depression( β=0.09?0.22, P<0.05) . Among participants whose husband or wife had higher level of depression,couple's personality similarity had stronger effect on his/her per?ceived marital quality. Conclusion Husband and wife personality similarity is related to marital quality signifi?cantly,and the spouse depression plays a significant moderating role in this relationship.

Objective: To study and compare the views on cancer associated information and communication needs of cancer patients among cancer patients, their relatives, doctors and nurses, and other groups of people. Methods: A total of 501 cancer patients, 169 relatives,86 doctors and nurses, 176 healthy elderly people and 505 first grade college stu- dents were asked to complete the Information Preference Questionnaire of Cancer Patients and 2 questions regarding gen- eral information amount and content (IPQCP+2), and the Information Need Questionnaire (INQ). The elderly and the stu- dents were asked to complete two sets of IPQCP+2 and INQ in two roles: one as themselves and the other as patients. All data were analyzed in detail. Results: The views of different groups are significantly different. The differences include the viewpoints on whether to disclose the diagnosis of cancer and to inform the life expectancy to cancer patients, and whether the patients should participate in decisions about their medical care and treatments. The mean score of IPQCP on the over- all items and the 4 dimensions of all groups, and their opinions on general information amount and content for patients are significantly different. Conclusion: The views of different groups of people on cancer associated information and commu- nication needs of cancer patients are different. The views and requests of cancer patients themselves are the basis of doc- tor- patient communication. The prevention of cancer should be based on the characteristics of different groups of people and the patients’views should be considered.

Objective To investigate the effect of the mascarinic acetylcholine receptor (mAChR) agonist Oxo-tremorine-M (Oxo-M) on glycinergic spontaneous inhibitory postsynaptic currents (sIPSCs) and micro-inhibitory postaynaptic currents (mIPSCs) in lamina Ⅱ neurons in the spinal cord of rats. Methods Glycinergic IPSCs (sIPSCs and mIPSCs) in lamina Ⅱ neurons of spinal slices were recorded using the whole-cell voltage-clamp method. The non-selective mAchR ngonist Oxo-M was applied through bath perfusian. The effects of Oxo-M 1, 3, 5 and 10 μmol/L on sIPSCs and mIPSCs were examined. Results Oxo-M at the concentrations of 3-10 μmol/L significantly increased the frequency of sIPSCs without changing the amplitude in 16 lamina Ⅱ neurons tested. Interestingly, when the concentration of Oxo-M was increased to 10 μmol/L, the potentiating effect of Oxo-M on the frequency of slPSCs was decreased as compared with 3 μmol/L Oxo-M in the above 16 neurons. The slPSCs were completely abolished by 2 μmol/L strychnine. Atropine, the specific mAChR antagonist, completely blocked the effect of Oxo-M on the frequency of sIPSCs. In 9 additional lamina Ⅱ neurons, 1-10 μmol/L oxo-M failed to alter significantly the frequency and amplitude of glycinergic mIPSCs. Conclusion Activation of mAChRs in the somatodendritic site of glycinergic interneurous increases the synaptic glycine input to spinal dorsal horn neurons, but not in a dose-dependent manner.

Objective To investigate the effect and safety of photodynamic therapy (PDT) with topical aminolevulinic acid (ALA) in moderate to severe acne. Methods Seventy patients with moderate to severe acne were randomly divided into two groups, one group was treated with topical ALA-PDT for 1-3 sessions with an interval of 2 weeks, the other group received oral isotretinoin 10 mg twice a day for 6 weeks. Patients were evaluated for efficacy on week 2, 4 and 6 after the initial treatment. A 3-month follow up was performed to monitor adverse events following the end treatment. Results The total effective rate was 97.1% in ALA-PDT group after 1-3 sessions of treatment, 80.0% in the control group on week 6, and the difference was significant between the two groups (P<0.05). Acne lesions tended to recur more slightly with a longer remission period in ALA-PDT group than in the control group. A temporary and local pigmentation was observed in some patients treated with ALA-PDT, but no scar was noticed. Conclusion Topical ALA-PDT is a simple and effective treatment option for moderate to severe acne with mild side effects.

Objective:To evaluate the effects of increasing end-tidal concentrations of sevoflurane and increasing stimulation voltage on motor evoked potentials,so as to provide evidence in making anesthesia plan for intraspinal tumor surgery.Methods:In the study,48 patients scheduled to undergo intraspinal tumor surgery [American Society of Anesthesiology,(ASA)Ⅰ-Ⅱ,18-65 years old]were enrolled. After general anesthesia induction,the patients were assigned to receive sevoflurane anesthesia of increa-sing end-tidal concentration in the sequence of 0.0%,0.5%,1 .0% and 1 .5% respectively,under a background of propofol and remifentanil.All the observations were done before the important steps of sur-gery.Remifentanil infusion rate was 0.2 μg /(kg·min),while the propofol infusion rate was adjusted to maintain the bispectral index values within the range of 30-50.At each concentration,4 stimulation voltages of 300 V,400 V,500 V and 600 V were employed to elicit motor evoked potentials (MEPs). The amplitude and latency of each MEP were compared.The success ratio was also recorded.Results:The concentration of sevoflurane and the stimulation voltage had impacts on the amplitude and latency of MEPs.Under each stimulation voltage,the MEPs amplitude decreased following increasing end-tidal sevoflurane concentrations,and significant differences were found in comparing 1 .5% sevoflurane (left 20.50 μV,70.71 μV,135.97 μV,190.00μV ,right 14.29 μV,50.71 μV,73.10μV,77.50μV) with 0.0% sevoflurane (left 143.00 μV,388.10 μV,484.53 μV,500.00 μV,right 176.00 μV, 407.60 μV,384.35 μV,451.00 μV)and 0.5% sevoflurane (left 100.00 μV,362.57 μV,444.05μV,435.00 μV,right 115.00 μV,207.15 μV,258.34 μV,358.50 μV),left χ2 =27.46,P<0.01,right χ2 =60.49,P<0.01;left χ2 =20.73,P<0.01,right χ2 =55.05,P<0.01;left χ2 =34.25,P<0.01,right χ2 =33.58,P<0.01;left χ2 =28.61,P<0.01 ,right χ2 =49.04,P<0.01;while there were no statistical differences in the latency changes (P =0.26 ).Under each end-tidal sevoflurane concentration,the MEPs amplitude increased following increasing stimulation voltages,and significant differences were found in comparing 300 V (left 143.00 μV,100.00 μV,61.50 μV,20.50μV ,right 176.00 μV,115.00 μV,41.07 μV,14.29 μV)with 400 V (left 388.10 μV,362.57μV,198.81 μV,70.71 μV,right 407.60 μV,207.15 μV,89.00 μV,50.71 μV)and 500 V (left 484.53 μV,444.05 μV,216.24μV,135.97 μV,right 384.35 μV,258.34μV,187.50μV,73.10μV)and 600 V (left 500.00 μV,435.00 μV,344.00 μV,190.00 μV,right 451.00 μV,385.50μV,156.00μV,77.50μV),leftχ2 =45.55,P<0.01,rightχ2 =25.73,P<0.01;leftχ2 =46.67, P<0.01,right χ2 =55.30,P<0.01;left χ2 =47.36,P<0.01,right χ2 =47.82,P<0.01;left χ2 =38.67,P<0.01,right χ2 =45.87,P<0.01;while the latencies were decreased,and significant dif-ferences were found in comparing 300 V with 400 V and 500 V and 600V(left F=7.50,P=0.01 ,right F=13.33,P<0.01),but the differences had little clinical significance.The success ratio decreased by increasing end-tidal sevoflurane concentration,and significant differences were found in comparing 1 .5%sevoflurane (left 43.8%,70.8%,77.1%,81.3%,right 37.5%,60.4%,75.0%,66.7%)with 0.0%sevoflurane (left 79.2%,87.5%,95.8%,93.8%,right 75.0%,95.8%,95.8%,95.8%)and 0.5%sevoflurane (left 72.9%,89.6%,95.8%,95.8%,right 66.7%,89.6%,95.8%,97.9%);the suc-cess ratio increased by increasing stimulation voltage,and significant differences were found in comparing 300 V(left 79.2%,72.9%,62.5%,43.8%,right 75.0%,66.7%,60.4%,37.5%)with 400 V(left 87.5%,89.6%,77.1%,70.8% ,right 95.8%,89.6%,79.2%,60.4%)and 500 V(left 95.8%, 95 .8%,9 1 .7%,77 .1%,right 95 .8%,95 .8%,8 1 .3%,75 .0%)and 600 V (left 93 .8%,95 .8%, 89.6%,81.3%,right 95.8%,97.9%,89.6%,66.7%),but there were no statistical differences in the success ratio of MEPs between the group with stimulation voltage of 600 V ,end tidal sevoflurane concen-tration of 1 .5% and the group with stimulation voltage of 300 V,end tidal sevoflurane concentration of 0.0% (P=0.22).Conclusion:Sevoflurane inhibited MEPs in a dose-dependent manner.It can de-crease the amplitudes and prolong the latencies.But increasing stimulation voltage will facilitate MEPs monitoring and increase the success ratio.Sevoflurane can be used in larger parts of MEPs monitoring surgery by increasing the stimulation voltage.
