Methods: A rat model of migraine was made with nitroglycerol. The rats were treated by pricking blood. Rat behavior was observed. Brainstem c-fos and c-jun gene expression was examined by immunohistochemistry. Results: Ear redness improved significantly, the number of head scratchings decreased obviously (P<0.05) and c-fos and c-jun expression was reduced markedly (P<0.01) in the treatment group after pricking blood compared with the model group and the blank group. Conclusion: Pricking blood treatment can improve behavior indices and reduce c-fos and c-jun positive expression in migraine rats.

Objective To investigate the mechanism of rosiglitazone on human leukemia cell line HL-60 in vitro.Methods Inhibition of HL-60 cell proliferation was shown by MTT array;cell cycle and apoptosis of human leukemia cell line HL-60 was detected by flowcytometry(FCM);expression of PPAR?,p21WAF1,Bax and bcl-2 was examined by SP immnocytochemical and western blotting.Results Rosiglitazone significantly inhibited proliferation of HL-60 cell and the inhibition effects had a dose-and time-dependence.The inhibition fraction of HL-60 cell to 100?mol/L rosiglitazone for 48h was 77%.Flow cytometry analysis revealed that proliferation of HL-60 cell treated with 10~100?mol/L rosiglitazone significantly inhibited.50~100?mol/L Rosiglitazone cold induce apoptosis of HL-60 cell.SP immnocytochemical found the nuclear translocation on PPAR?,and western blotting revealed that the Bax expression was increased,while the bcl-2 and NF-?B expression was decreased.The expression of PPAR?,Bax,bcl-2 and NF-?B had no change by GW9662,a specific inhibitor of PPAR?.Conclusion Rosiglitazone could induce apoptosis in HL-60 cells which may be involved in the activation of PPAR? and down-regulation of Bax and up-regulation of Bcl-2 and NF-?B protein.

Objective To investigate long-term biological variability of serum lipids in Chinese. Methods Serum lipids in a Chinese population with relatively stable life styles were monitored with standardized measurements for 1 year (specimens were taken bimonthly) (23 subjects) or 10～15 years (yearly) (100 subjects). Results The total intra-individual variability (analytical and biological variations combined) of total cholesterol, triglycerides, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol averaged 10%, 28%, 16% and 18%, respectively. Conclusion Biological intra-individual variability is a major source of inaccuracy of cardiovascular risk assessments based on lipid measurements. Measures need to be taken to minimize biological variation when medical decisions are to be made in the treatment of lipid disorders.

Objective To reproduce and validate the hexokinase reference method for glucose detection and compare other 5 routine glucose kits with this reference method. Methods The CDC hexokinase reference method for glucose detection was established and the performance was validated through testing a standard reference material (SRM) and participating in the IFCC ring-trial for reference laboratories for glucose evaluation. The CLSI EP 9-A2 protocol was used to compare the 5 routine glucose kits with the hexokinase reference method. Forty serum samples were analyzed by 5 routine kits and the hexokinase reference method. Results When SRM 965a was determined by the reference method,the bias of level 2 and level 3 were 0. 93%, -0. 23% respectively. The results for IFCC ring trial were within the accepted range. For the 5 routine kits, the confidence intervals of the predictive bias at the medical decision point Xc (Xc = 6. 11 mmol/L) were all within the range of defined acceptable error (10%) and the range of biological variation bias (6.9%). Conclusions The hexokinase reference method for serum glucose was reproduced in our lab. The serum glucose results measured with 5 routine kits were different from results detected with the reference method, but the bias was acceptable,and it will not affect the detection results.

Objective To investigate the self-care agency level and analysis the relationship between the self-care ability level and the prognosis of the patients with upper gastrointestinal bleeding caused by liver cirrhosis.Methods In the first stage,78 cases of liver cirrhosis patients complicated with first eruption of upper gastrointestinal bleeding were selected,the Exercise of Self Care Agency Scale (ESCA)was adopted to assess the self care ability of patients,the results underwent analysis.In the second stage,according to the results that the proportion of scores accounted for total score ratio,the patients were divided into low,medium and high level groups.By prospective studies,through telephone follow-up and clinic follow-up,the evaluation items of patients were collected,and the survival status of patients within 3 months after discharge was compared.Results For patients with upper digestive tract bleeding caused by liver cirrhosis,the self-care scored (84.07±17.38) totally,among 78 patients selected,15.4％ (12/78) was in the low level,75.6％ (59/78) was in the medium level,9.0％ (7/78) was in the high level.The self-care ability increased in conjunction with decreased mortality rate.The mortality rate in the lower level group was 8/12,33.9％ (20/59) in the medium level group,1/7 in the higher level group,there was statistically significant difference,x2=6.3,P＜0.05.The MELD-Na scores in the lower,medium and higher level groups wererespectively 34.03±4.62,22.57±3.05,12.87±1.36,F=6.0,P＜0.05.Likewise,complication incidence rates were negatively correlated with self-care ability,r =-(0.525-0.189).Conclusions The self-care ability of patients with gastrointestinal bleeding caused by liver cirrhosis is in the medium level,and it exercises certain influence on prognosis of patients.Attention should be paid to cultivation of self-care ability of patients in clinic.
