Objective To observe the student's endocrine metabolism in senior high school during different periods.Methods 328 senior middle school students in different periods were investigated and the blood concentration of adrenaline(N),norepinephrine(NE),cortisol(CS),interleukin-2(IL-2),interleukin-6(IL-6)were measured by radioimmunoassay and Magnetic Solid Phase Separation-Enzyme Immunoassay,and at the same time,students in vocational high school were contrasted.Results As the university entrance examination was coming,the values of N,NE and CS were apparently rising,while the values of IL-2 and IL-6 were going down.The biodifferences.Grade Two and Grade One(t=1.96～2.52,P＜0.05).Grade Two and the control(t=3.53～4.20,P＜0.01)were different significantly,while Grade one and the control had no obvsious difference(t=1.18～1.92,P＞0.05).Conclusion N,NE,CS of the senior hish school students in Grade Three were higher,while IL-2and IL-6 were lower than that of the Grade Two.

Objective: To comprehensively compare the qualities of Codonopsis Radix from the different planting areas for regionalizing the planting areas. Methods: The main traits and chemical compositions of 38 samples of Codonopsis Radix from the different planting areas in Jiuzhaigou County were comprehensively compared by SPSS 17.0 software using principal component and cluster analysis. Results: Five principal components whose accumulated variance contribution rate was over 85.604% were obtained. Based on these principal components, 38 samples of Codonopsis Radix from the different planting areas in Jiuzhaigou County were clustered into four groups by within-groups linkage cluster methods. Conclusion: Principal component and cluster analysis are reliable to comprehensively evaluate the quality of Codonopsis Radix. Significant differences among these samples from the different planting areas in Jiuzhaigou County are obvious. The standardization of cultivation techniques and application should be speeded up.

Purpose:To study the secretion and gene expression of Angiogenesis factors in the patients with CML and study the effect of Angiogenesis in the occurrence and development of CML. Methods:Concentration of VEGF in peripheral blood was determined by using ELISA. Myeloid tissue was extracted from all CML cases and ITP patients to detect MVD by using CD34 labelling. At the same time the level of VEGF,b-FGF were detected by using RT-PCR in both peripheral blood and myeloid cells.Results:Our results showed that the concentration of VEGF was obviously higher in the peripheral blood of CML patients(177.53?153.45 pg/ml) than in those of control group(73.12?19.82 pg/ml). The gene expression of VEGF and b-FGF were both higher than those of control group. The difference has statistical significance(P

Objective To discuss X-ray, CT and MR findings of primary bone lymphoma. Methods The X-ray, CT and MR findings of 6 cases with non-Hodgkin lymphoma of bone proved pathologically were retrospectively analysed.Results The average age of 6 cases was 51 years old and the lesions all localized at long bone(especially the metadiaphysis) and pelvis. Imaging findings included: osteolytic or moth-eaten bone destruction,surrounding soft tissue mass formation which generally exceeded the extents of bony changes, the cortex bone was destructed and discontinuity.Conclusion primary bone lymphoma has prevalent age and certain imaging specificity.

Objective To observe effect mechanism of L-arginine (L-arg,a precurory substance of nitric oxide sythesis) in proveting proteinuria in adriamycin-induced nephrosis model of rats.Methods Nephrosis model of 16 rats was established by tail vein injetion with adriamycin,then the 16 rats were divided into two groups;model group and treatment group with L-arg administration (treated group),the levels of nitric oxide(NO),endothelin-1(ET-1),renal function,and pathological changes were observed in the two groups.Results The successful nephrosis model of rats was indentified with optical and electron microscope technique.Proteinuria was occurred in the two groups,but proteinuria degree in treated group was lighter than those of model group,however NO level was higher than that of model group,there was negatively correlation in the levels of NO and ET-1 between both groups,pathological alteration under electron microscope observation was obviously less in the treatment group than those of the model group.Conclusions On basis of these findings,author consider that the L-arg could reduce proteinuria output by promoting NO synthesis and suppress the ET-1 production.

Doctors ought to belong to a social stratum with fairly high incomes. The high input and long cycle that is essential to becoming a high-caliber doctor constitute the high costs of the medical profession; high technology, high responsibility and high sacrifices constitute the high risks of the medical profession; the contrast between the input of high intelligence, high academic degree, and high expertise and the output of low economic income tends to warp the minds of doctors. The inversion of the burden of proof in medical lawsuits has practically put doctors on the weak side. Their rights and interests as well as their practice circumstances have been disregarded. For the sake of the development of the health cause, it is imperative to respect the labor of doctors and to provide them with sound survival circumstances.

To explore the relativity between alexithymia and cognitive function in somatoform disorder patients.A total of 40 patients aged 18-65 years fulfilling the criteria of ICD-10 for somatoform disorders were recruited as research group.And 40 normal healthy subjects were selected as control group.Toronto alexithymia scale-20 (TAS-20) was employed to examine the alexithymia.And cognitive abilities screening instrument (CASI) was used to measure their cognitive ability.The 9-factor scores and total score of CASI test in patients with somatoforill disorder were significantly lower than those in the normal controls (P ＜ 0.05 or ＜ 0.01).The 3-factor scores and total score of TAS-20 test in patients withsomatoforill disorder were significantly higher than those in the normal controls (P ＜ 0.05 or ＜ 0.01).In research group,CASI scores were negatively correlated with the TAS-20 scores (P ＜0.05 or 0.01).

Objective To observe and analyze the correlation between the DNA methyltransferase-3B (DNMT3B) gene single nucleotide polymorphisms (SNP) rs 1569686 and the susceptibility to colorectal cancer (CRC) in Tianjin Han population.Methods A case-control study was performed.89 CRC patients and 94 normal controls were examined,and Sequenom MassArray system was applied to detect the genotype of rs1569686 in DNMT3B gene polymorphisms.The association results were analyzed of the SNP and CRC.Results The frequencies of genotypes TT,GT and GG at SNP rs1569686 were 74.2％,24.7％ and 1.1％ in CRC patients respectively,which there were no significant differences from that in controls(73.4％,23.4％ and 3.2％; P＞0.05).Conclusion It suggests that the SNP rs1569686 of DNMT3B gene may not be related to susceptibility of CRC in Tianjin Han population.
