Objective To investigate the different effects of clozapine and risperidone on levels of blood glucose in patients with schizophrenia. Method 200 qualified cases selected from psychiatric department were divided into two groups randomly, of which 100 cases accepted the treatment with clozapine and the other 100 cases with risperidone. Blood glucose tests were used before treatment ,4 weeks after treatment and 8 weeks after treatment Results There was significantly higher blood glucose level in clozapine－ treated group than in risperidone－ treated group after 4 or 8 weeks treatment. The number of cases who had elevated blood glucose level (>6.1 mmol/L) in clozapine－ treated group was significantly more than in risperidone－ treated group. Conclusion The glucoregulatory abnormality which leads to glucose elevation in clozapine－ treated patients is greater than in risperidone－ treated patients. Additional motivation to clinical monitor for antipsychotic treatment－ related hyperglycemia is indicated.

This paper aimed to describe the concept of the cancerous person's supportive care needs and the current situation of the study on this issue abroad so that we can analyze the factors which influence the needs,and we also try to elaborate the shortcomings and study expectation on cancerous person's sup portive care study.

Joint -Up Community is crucial to the community health services. Joint - Up is an kind of co -operation, but it is neither the co - operation of bureaucracy nor that of the market model. The new relationship of Joint - Up is based neither on responsibility nor on contract, but on equal partnership. It is vital to solve the ethical plight of health services in country.

Most of the current medical humanities education focuses on the moral aspects without good theoreti-cal basis and specific practices on the medical institution and daily life.The article dates back to the origins of So-cial Science based on the concept caregiving put forward by the medical anthropologist Arthur Kleinman,and states that the ultimate purpose of Social Science is to make response to the social suffering and provide caregiving for it.Caregiving as moral experience is response to social suffering and attracts much importance,because it pro-vides both the theoretical basis and practical means for the current medical humanities education.Its characteristics of caregiving as moral experience to social suffering and caregiving as reciprocity meet the demands of current notion of Big health in China.

Objective To investigate optimal radiation dose for digital radiography by researching the correlation between radiation dose and image quality of high kV chest radiography.Methods The kV of chest radiography was setted on 120 kV while mAs was changed.The chest radiography phantom and the contrast detail phantom CDRAD2.0 were exposed by DR with different mAs from 1 to 25 mAs.The entrance doses were measured for all exposures and the images were read independently by 5 observers on a higher resolution monitor of diagnosis work station.The image quality figure (IQF) was measured for each image.Comparison of the mean IQFs with different exposure doses were conducted in order to determined which was the optimal exposure condition for high kV radiography.The image quality of normal adult using different mAs,4 and 10 mAs for high KV chest radiography was compared.Results When the mAs was increased from 1 to 25 mAs,the entrance doses varied from 0.067 to 1.468 mGy.With the entrance doses increasing,the value of IQF was decreased (F =31.00,P ＜ 0.05).The values of IQF were statistically different between 1 and 4 mAs(F =15.3,P ＜0.05),and between 10 and 25 mAs(F =9.74,P ＜0.05).At 4 and 10 mAs with the entrance dose 0.250 and 0.606 mGy,the synthesis score of chest high kV radiography from two kinds of exposure dose was (24.8 ± 1.64),(25.8 ± 2.05),with no statistically significant difference.Conclusions For digital radiography,increasing radiation dose can improve image information.The optimal entrance dose of high kV chest radiography for standard body was about 0.250 mGy.

Obesity has been identified as one of the risk factors for malignant neoplasms,such as breast cancer.Epidemiological data shows that obesity is closely related to the development and progression of breast cancer.The pathogenesis may involve in estrogen,insulin,leptin,adiponectin and inflammation factors.Therefore,maintain normal body weight may contribute to the prevention of breast cancer.

Objective To investigate the therapeutic effects of Tongxinluo and its influence on the expression of CD40 and CD40L in artherosclerosis rabbits. Methods 60 male rabbits were divided into three groups randomly,20 of each group: normal control group, model group and Tongxinluo group. The rabbits in model group and Tongxinluogroup were used to prepare the atherosclerosis model induced by high-cholesterol diet. The levels of ET-1, NOwere measurde. Before and 12 weeks after durg treatment,serum total cholesterol ,plaque areas and ratios of intima/media thickness were detected. The expression of CD40 and CD40L mRNA were determinated by quantitive RT-PCR. Results Serum total cholesterol level of Tongxinluo group was decreased compared with model group ( P < 0. 05 ), and they were both much higher than those of normal control group ( P < 0. 01 ); as compared with the model group, aortic plaque areas and ratios of intima/media thickness in Tongxinluo group reduced significantly [ (0.56 ± 0. 07) vs ( 1.16±0.08),P<0.01;(36.88±2.38)% vs (76.58 ±2.86) %,P <0. 0l] ;The expression of CD40 and CD40L mRNA also decreased in Tongxinluo group with statistic significance[ (0.798 ± 0.115 )、 (0. 592 ± 0. 132) vs (0.686±0. 132) 、(0.498 ±0. 108) ,P <0. 01 ) ]. Conclusion Tongxinluo had the ability to anti-artherosclerosis and its possible mechanism was down-regulate the expression of CD40 and CD40L.

Objective: To evaluate the therapeutic effect of combining use of acupuncture and drugs on rheumatoid arthritis(RA) in the early and the active stages of by the imaging of bone and joint with 99m TC-methlene diphosphate(MDP). Methods: 102 cases of RA in the early and the active stages were randomly allocated into the compound Fengshining group (Group A),acupuncture group(Group B), and compound Fengshining plus acupuncture group(Group C).They were treated for 30 days. All patients were examined before treatment and after treatment by 99m TC-MDP imaging of the whole body, hands and feet, and analyzing method of random interested region was used to count the ratio of radioactivity in the affected area of RA to radioactivity in adjacent normal bone(T/TN). Meanwhile, joint swelling index, joint tenderness index, morning stiffness, gripping force, and erythrocyte sedimentation rate (ESR) were also observed. Results: T/TN of the Group A after treatments had no significant difference comparing with that before treatment(t = 1.35, P＞0.05), while the Group B and C had significant differences(t = 5.31, t=8.97, P＜0.01). The changes of clinical and experimental examination in the Group C had more significant differences than those in the Group A and B(P＜0.05).Conclusion: Acupuncture therapy could promote RA recovery, and combining use of acupuncture and compound Fengshining had better effect.

Objective:To study the antioxidant activity and anticancer activity of tea polysaccharide.Methods:Tea polysaccharide was extracted and purified by gel permeation chromatography from coarse old green tea leaves obtained from Wuyuan county of Jiangxi province in China.The antioxidant activity of the tea polysaccharide was evaluated by determining the change in absorbancy after heat-induced oxidation in a linoleic acid system with ?-carotene,the decoloration of the 1,1-diphenyl-2-picrylhydrazyl and the elimination of superoxide generated from autoxidation of pyrogallol.On the other hand,the anticancer activities of tea polysaccharide at different concentrations were evaluated by MTT assay using two colon cancer cell lines(HCT-15,Caco-2).Results:Tea polysaccharide possessed distinctive antioxidative activity.The anti-proliferation capabilities of the tea polysaccharide against the tested human colon cancer cell lines were different under the designed experiment conditions.The tea polysaccharide with high purity exhibited good anti-proliferation activity against HCT-15 at concentration of 7.0?mol/L.Conclusion : Tea polysaccharide has remarkable antioxidative and anticancer bioactivities..
