Objective To observe the effect of combination therapies with methotrexate, sulfasalazine and hydroxychloroquine on hyperlipemia of rheumatoid arthritis.Method From 2009 November to 2010 November, 68 RA inpatients and outpatients in the department of rheumatism of our hospital were randomly divided into two groups: A group and B group, 34 cases in each group. The patients in A group were given combination of methotrexate, sulfasalazine, hydroxychloroquine sulfate for the treatment of RA,patients in B group, based on A group's treatment, were treated by xuezhikang. Some indexes were observed in two group before treatment and 6 months after treatment, including cholesterolTC,low density lipoprotein cholesterol LDL-C , triglyceride TG , high density lipoprotein cholesterol HDL-C , swelling index, joint pain index, time of morning stiffness, C-reactive protein CRP , erythrocyte sedimentation rate ESR and DAS28. Results After 6 months’ treatment, the serum levels of TC, TG,, LDL-C, both in two groups of patients, were lower than those before treatment, and HDL-C was higher than that before treatment, there were significant differences (P<0.05 or P<0.01) . After 6 months of treatment,DAS28,ESR,CRP,joint tenderness,joint swelling and morning stiffness time, both in two groups RA patients, significantly reduced compared with before treatment, there were a very significant difference (P<0.05 or P<0.01) .After treatment, the above indexes had no statistically significant difference between two groups (P>0.05) . Conclusion RA patients have abnormal blood lipid levels, disease-modifying anti-rheumatic drugs have effect on blood lipid during remission joint disease in RA patients.

Objective To explore the effects of psychological intervention on negative emotions and quality of life in patients with rheumatoid arthritis (RA).Methods A total of 112 patients with rheumatoid arthritis were divided into two groups:the intervention group and the control group.All patients were given drugs for treatment of RA.Additionally,patients in the intervcntion group were received psychological intervention.Zung's self-rating depression scale (SDS),Zung's self-rating anxiety scale (SAS),RA disease activity score (DAS28),visual analog scale (VAS),disability index of health assessment questionnaire (HAQ-DI) were assessed,and the related laboratory parameters such as erythrocyte sedimentation rate (ESR),C reactive protein (CRP),rheumatoid factor (RF)were determined.Results 6 months after the treatment,there were significant differences in SDS and SAS between the treatment group and the control group [SDS:(31.7±4.7)scores vs.(29.6±4.4)scores; SAS:(34.7±5.3)scoresvs.(32.6±5.1)scores; t=2.441,-2.119,both P＜0.05].The patients with tender joints,joint swelling and morning stiffness time were less in the treatment group than in control group [(5±3) vs.(7±4),(4±3) vs.(5±3),(36±16) min vs.(42±19)min.respectively,t=2.054,2.393,1.995,all P＜0.05].The scores of HAQ-DI,VAS and DAS28were lower in the treatment group than in control group [(0.89±0.73) vs.(1.20±0.77),(6.1±1.6) vs.(6.8±1.8),(3.2±1.7) vs.(3.9±1.9),respectively,t=2.136,2.406,2.135,all P＜0.05].There was a significant difference in CRP between the treatment group and the control group [(34±14) mg/L vs.(37± 17)mg/L,t=2.406,P＜0.05].Conclusions Psychological intervention can improve the negative emotions and quality of life in patients with rheumatoid arthritis.

Malignant bowel obstruction (MBO) is common in patients with bowel or gynaecological canc-er. Although surgery is the primary treatment for most patients with MBO, it should not be undertaken rou-finely in patients with poor prognosis. Nasogastric drainage is only a temporary measure. Serf-expanding me-tallic stents are optimistic in malignant obstruction of the gastric outlet and proximal small bowel.

Gastrointestinal stromal tumours(GISTs)are the most common primary mesenchymal tumours of the gastrointestinal tract and the disease is occasional and asymptomatic. Though the high rate of recur- rence after surgery, operation remains the firstline treatment of the GIST without metabasis. With the consid- eration the molecular biology of tumor, the treatment including surgery and molecular targeted therapy can im- prove the prognosis of GISTs.

Objective To develop a mental maturity test for adults.Methods On the basic of correlative theories,the structure of Adults Mental Maturity was established by using interview and exploratory factors analysis. The reliability and validity of this test were examined. Results Through exploratory factor analysis the test was of six factors self-insight, social cognition, emotion management, social contact style, adapting ability, loving ability. The reliability of test was 0.621～0.853, and the retest reliability was 0.431～0.831. Conclusion The test of mental maturity for adults is of better reliability and validity, and can be used in practice.

Objective To explore the effects of low-dose CT scan on diagnostic quality of images and the radiation dose to the lens.Methods 60 cases were scanned in axial orientation at different mA.Lens radiation dose was measured and image quality was evaluated.Results Image quality score of group A was(11.2 ± 0.7)points,higher than the group C(4.9 ± 1.8)points(t =12.634,P ＜0.05),and score difference of group B(10.6 ± 1.1)was significantly different(P ＞ 0.05).CTDIvol of group A,group B and group C were 18.32mGy,7.63mGy and 4.58mGy,group B,group C and group A difference was statistically significant(t =15.625 and 14.037,P ＜ 0.05).Group B and C groups difference was not statistically significant(P ＞ 0.05).Conclusion Low dose CT scanning(50mA)in orbit not only could assure the image quality,but also decrease the radiation dose.

Objective To study the drug-time process of aurantiin in Rhizoma Drymariae in vivo.Methods By the optimization of the chromatographic condition,a reversed-phase HPLC was established to measure the content of aurantiin in the serum and the tissues of rats.Results After administration of total flavones of Rhizoma Drymariae to the rats by gavage,aurantiin started to be absorbed in 30 minutes and arrived at the peak in 90 minutes.The blood drug concentration decreased evidently 4 hours after gavage and maintained at a certain level in 8 hours.The drug concentration was highest in the stomach and bowels,but decreased quickly.The concentration in the liver,lungs and kidney came next and can be determined in the muscles and fat;however,it was very low or zero in the brain.Conclusion This method is convenient,sensitive,rapid and without the interference of other impurities.It is suitable for the determination of aurantiin content in the serum and tissues of rats.Administering total flavones of Rhizoma Drymariae to the rats by gavage,aurantiin is absorbed slowly and maintains for a long time and subsides slowly in the blood.
