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 study the false positive of enzyme linked immunoinhibition continuous assays to detect CK-MB in clinic,to reasonably explain the results of detection and to get correctly the project of solving.Methods A total of 125 serum specimen of non-myocardial infarction patients were detected by enzyme linked immunoinhibition continuous assays,in retrospective study.To analyze the factors which made the CK-MB enzymatic activity unit pseudo-rising.Results Total CK-MB enzymatic activity was low in 86 serum specimen of adult patients with non-myocardial infarction,but in the patients with tumor,encephalic infarction and allergic disorder the pseudo-positive ratio of the CK-MB enzymatic activity was high.There were 53 cases, in which CK-MB activity accounted for 6%-21% enzymatic activity of CK, and 6 cases accounted for more than 38% in 59 cases in which the CK-MB activity was more than 5% enzymatic activity of CK.In 38 neonate cases, the enzymatic activity of CK ranged from 145U/L to 1974U/L,In 1 case of neonatal respiratory distress syndrome CK-MB activity accounted for more than 90% enzymatic activity of CK.Another haemolytic sample led to false positive result.Conclusion The phenomenon of enzymatic activity rising in the serum specimen of non-myocardial infarction patients may be caused by the factors of lots CK, CK-BB and AK in serum.Those materials maybe have effects on the action between McAb and M subunit of the CK.Some non-inhibit CK-M and the M subunit with B subunit may participate the enzymatic activity together.Because of the shortcoming of method,the single assay should not be taken as the diagnostic basis.

OBJECTIVE:To investigate the curative effect of metoprolol in treating chronic congestive heart failure (CCHF) and to discuss its administration technique.METHODS:A total of 72 patients with CCHF were randomly divided into treatment group and control group. The patients in the control group were treated with conventional therapy for heart failure,while those in the treatment group were treated with additional metoprolol at an initial dose of 6.25mg bid but gradually increased to 100mg bid for 24 weeks apart from the conventional therapy.RESULTS:The total responsive rate(RR) in the treatment group(88.9%) was significantly higher than in the control group(63.9%)(P

BACKGROUND: Generally, repairing the injuries of sketetal muxcle is to suture the epimysial and exterior muscular nerve. OBJECTIVE: To determine the intramuscular nerve effects on the recovery of lacerated musculus rectus femoris. DESIGN, TIME AND SETTING: The randomized control animal experiment was performed at the Animal Experimental Center, Chongqing Medical University from September 2006 to August 2007. MATERIALS: Twenty New Zealand rabbits weighing 2.0-2.5 kg were used to establish models of right skeletal muscle injury; left side was used as controls. METHODS: Twenty rabbits were randomly divided into two groups. Rabbits in the intact intramuscular nerve group underwent complete muscle laceration with intramuscular nerve intact. Musculus rectus femoris was traversed at 4.0-5.0 mm from nerve entry point. Rabbits in the intramuscular neurotmesis group underwent complete muscle laceration, but intramuscular nerve was cut concomitantly at the same place as above. MAIN OUTCOME MEASURES: 28 weeks after surgery, wet weight and isometric contraction of musculus rectus femoris were detected. Morphological change of musculus rectus femoris was observed by Hematoxylin & Eosin Staining. Fibrous degree was measured by Masson trichrism staining. Myofibrillar type was examined by myosin ATPase staining and tetrazolium staining method of reduced coenzyme Ⅰ to calculate cross-sectional area of muscle fiber. RESULTS: Compared with the controls, wet weight and isometric contraction of musculus rectus femoris reduced in the intramuscular neurotmesis group (P
