Objective To explore the mutation in corel β3-galactosyl-transferase specific molecular chaperone(Cosmc、no-coding region and it's effects on the transcription level of Cosmc in Tn antigen positive tumor cells.Methods The Tn antigen positive(Tn+)and negative(Tn-)cells were separated from tumor tissues by immune magnetic bead,then the genomic DNA(gDNA),total RNA were prepared by Qiagen AllPrep DNA/RNA mini kit. In these cells.the transcription levels of T-synthase and Cosmc mRNA were tested by RT-PCR.the DNA of Cosmc non-coding region was amplified by PCR,the mutation in Cosmc non-coding region were further detected by sequencing.Results There are no mutation appearing in Tn-cells,one or more mosaic sequence allele appearing in portion of patient's Tn-cells.Almost of the Tn+cells which separated from tumor tissues and Jurkat T cell exists mutation.but the mutation style and mutation point were not saine in different tumor.Thtee patient's Tn+cells have loss of hetemzygosity(LOH),four patient's Tn+cells and Jurkat T cell have point mutation.Although no difference of transcription level of T-synthase mRNA in Tn+ and Tn-cells.but the transcription level of Cosmc mRNA in Tn+ cell was much lower than that in Tn-cell.The ratio of T-synthase/Cosmc mRNA in Tn+ tumor cells was hiigher than that in Tn-cell.Conclusion The tumor Tn antigen arise from mutation in Cosmc non-coding region maybe result from transcription level decreased of Cosmc mRNA.

Proteomics is a science of investigating pathogenesis in the level of protein, making proteom as the object of study, based on the exhaustive study of protein. Protein chip array and SELDI-TOF-MS technology is a new technologic platform, and it has an extensive prospect for application. Present article reviews the cross-correlation technique and progress of study of proteomics, as well as its application in urinary tumors'research.

Objective:To detect the specificity killing effect of anti-CD4-epirubicin immunoconjugate on T origin lymphoma cells.Methods:The immunoconjugate was made by linking anti-CD4 monoclonal antibody with epirubicin using Dextran T10 as linkage. The affinity and the killing effect of the immunoconjugate in vitro and in vivo were detected by complement independent cytotoxicity, immuno-histochemistry, CFU-GM and ~ 125 I-anti-CD4 radio-immuno-imaging in nude mice.Results:Anti-CD4 immunoconjugate showed a strong affinity and specific killing effect to T origin lymphoma CEM cells.Conclusion:Anti-CD4-epirubicin and ~ 125 I-anti-CD4 could be used for diagnosis and treatment of T origin lymphoma.

According to the limited class hours and requirements of medicinary major curriculum application,this paper attempts to make some choice of physical chemistry teaching contents and emphasize on the first class,and also to explore bilingual teaching of partial chapters and experimental teaching.

【Objective】To observe the influence of medicated diet with spleen-invigorating and phlegm-removing herbs on the therapeutic effect of acupuncture for simple obesity.【Methods】Ninety-six female simple obesity patients with phlegm-damp retention in the interior due to spleen deficiency were equally randomized into two groups by simple random method.Groups A(n=48)and B(n=48)were given dietary control,acupuncture on acupoints of Zusanli(ST36),Pishu(BL20) and Feishu(BL13),and catgutembedment(CE)in auricular points of spleen,stomach and tri-energizer.Group A additionally took a medicated diet for invigorating Qi and strengthening spleen,removing phlegm and draining damp.After one-month treatment,body weight,index of body weight and height were measured,and serum levels of total cholesterol(TC),triglyceride(TG),low-density lipoprotein(LDL)and high-density lipoprotein(HDL)were determined.【Results】Body weight,index of body weight and height,and blood lipid levels were decreased in groups A and B after treatment(P

Objective:To study quality of life and life satisfaction among the elderly population dwelling in Ji'nan. Method:1386 elderly people were interviewed with“the Short-Form 36 Health Survey Scale”by the investigators who were trained in advance.Results:The prevalence rate of chronic diseases was 65.1%. The main influencing factors of life satisfaction were mental health condition, family harmony, marriage condition, chronic diseases, and income. The main influencing factors of life quality are life satisfaction, chronic diseases, mental health condition, activities of daily life, family harmony, and income.Conclusion:Life satisfaction is closely associated with life quality of elderly people. The physical, psychological, social and economic conditions have significant effect on life quality of elderly people.

Objective To analyze the risk factors of early renal damage in children with Henoch Schonlein purpura(HSP).Methods The clinical data of 196 children with HSP admitted to our hospital from April 2012 to January 2016 were analyzed retrospectively.They were divided into the renal damage group and non-renal damage group within 90 d after confirmed diagnosis.The related clinical data such as serum immunoglobulin and urinary microalbumin were compared between the two groups,and the risk factors of early renal damage in children with HSP were screened.Results There were significant differences between the two groups on age,joint symptoms,recurrent purpura,persistent rash,gastrointestinal bleeding and abdominal pain(with χ2 or t of 11.345,16.223,11.275,43.211,12.592,17.771,P<0.05).The white blood cell count,platelet count,immunoglobulin A(IgA) level and urinary albumin level also showed significant differences between the two groups(t=33.750,60.442,9.451,8.458,P<0.05).The multivariate regression analysis showed that the independent risk factors for early renal damage in children with HSP included age(OR=2.703),recurrent purpura(OR=2.721),persistent skin rash(OR=1.782),gastrointestinal bleeding(OR=11.472),abdominal pain(OR=2.046),IgA level(OR=1.221) and urine microalbumin(OR=3.214).Conclusion Age,recurrent purpura,persistent skin rash,gastrointestinal bleeding,abdominal pain,IgA level and urine microalbumin are closely related to early renal damage in children with HSP.

Objective To observe the change of gastro-intestinal hormone levels about syndrome type of stagnation of liver qi, deficiency of spleen and stomach, liver qi stagnation and spleen qi deficiency in patients with irritable bowel syndrome (IBS), and to probe into the correlation between TCM syndrome type and gastro-intestinal hormone levels. Methods One hundred and three cases of patients with IBS were divided into liver qi stagnation group (35 cases), spleen and stomach deficiency group (30 cases) and liver qi stagnation and spleen qi deficiency group (38 cases), with normal group (10 cases) as control. Plasma motilin (MOT), somatostatin (SS) and cholecystokinin (CCK) were determined by radioimmunoassay. Result The plasma MOT level of spleen and stomach deficiency group was significantly higher than that in the normal controls (P
