The "Cancer Toxin" pathogenesis theory is an innovate theoretical system for cancer pathogenesis of Chinese Medicine, which was built on the basis of "Cancer Toxin" concept initially raised by Professor ZHOU Zhong-ying. The mechanism of the transformation from inflammation to carcinoma has become one of hot-points in the field of cancer research at home and abroad in recent years. We focused on discussing the relevance of the "Cancer Toxin" pathogenesis theory with the transformation mechanism from inflammation to cancer, provided evidence for using "Cancer Toxin" pathogenesis theory in intervening transformation from inflammation to cancer, hoping to guide for Chinese medical prevention and treatment of tumor.

Objective To explore the possible association between human leukocyte antigen(HLA) allele polymorphism and susceptibility to chlidren's acute lymphocytic leukemia(ALL).Method HLA alleles polymorphism in 38 cases with ALL and 35 healthy controls were determined by polymerase chain reaction(PCR) with sequence specific olignuleotide probe(PCR/SSO).Results The allele frequency of HLA-A01 significantly increased than control group(?2=4.947 P=0.026,RR=10.20),the frequence of A02 significantly decreased(?2=4.187 P=0.041,RR=3.13),the frequcnce of A33 significunt decreased than control group(?2=4.403 P=0.036,RR=0.21).Conclusion These results show that susceptibility to chlidren's ALL is positively related to HLA-A01,A33,especially A01 allele,while HLA-A33 to its genetic resistance.

Objective To evaluate autologous buccal mucosal patch grafting for correcting penile deformity in the surgical treatment of Peyronie's disease. Methods 14 patients with symptoms of Peyronie's disease for more than three months suffered from persistent pain ,severe curvature of the penile shaft and resistant to conservative treatment underwent plaque incision and autologous buccal mucosa patch grafting. Results Postoperative follow up has been 0.5 to 2years.The penile shaft became straight with no narrowing or indentation in 12 patients (86%) . In 14% of cases (2/14) some curvature of the penile shaft persisted and there was pain on erection.In all the patients there was no change in penile length. 86% of patients had overall satisfaction after surgery with improvement in psychological and social well-being. Conclusions The autologous buccal mucosal patch graft provides an anatomical and functional tunied substitute resulting in correction of the penile deformity in Peyronie's disease.

Objective To investigate the effect of cyclosporine A(CsA)on viral protein syn- thesis and hepatitis B virus(HBV)DNA replication in vitro.Methods The HBV DNA transfected cell line HepG2.2.15 was treated with different concentration of CsA(0.6-20.0?g/ml)for 4 days. Hepatitis B surface antigen(HBsAg)and hepatitis B e antigen(HBeAg)in supernatant were detected by enzyme-linked immunosorbentassay(ELISA);intracellular hepatitis B core antigen(HBcAg)mR- NA and HBV DNA were analyzed by RT-PCR and slot blot hybridization,respectively;the phospho- rylation at tyrosine acid position 402 of PyK2 kinase(PyK2 Y402)was detected by Western blot.Re- sults CsA could suppress the expression of HBsAg and HBeAg,and inhibit the HBV DNA replica- tion in a dose-dependent manner.The suppression rate of HBsAg and HBeAg under the action of CsA at the concentration of 10.0?g/ml for 4 days was 49.7% and 34.3%,respective;similar effect was observed on HBV DNA replication,HBV DNA was only 34.9% of the control at the concentration of 10.0?g/ml of CsA.The phosphorylation level of PyK2 Y402 was declined under the action of CsA at the concentration of 2.0?g/ml.Conclusions CsA can inhibit the expression of HBsAg,HBeAg and HBV DNA replication in the HepG2.2.15 cell line in a dose-dependent manner.Suppression of the phosphorylation level of PyK2 Y402 maybe involved in the mechanism of the inhibitory activity of CsA on HBV replication.

Objective To investigate the clinical effect of lentinan and thymopentin injection combined with PTP chemotherapy in oral squamous cell carcinoma patients, and to observe the effect of lentinan on serum tumor specific growth factor ( TSGF) , IgG, IgA and IgM and quality of life in patients with oral squamous cell carcinoma .Methods The clinical data of 80 cases of oral squamous cell carcinoma ( postoperative lymph node metastasis) confirmed by operation and pathology were analyzed retrospectively, and the diagnosis and treatment were analyzed.The control group were treated with PTP regimen, 80 ~120 mg/m2 of cisplatin, 50 ~80 mg/m2 of teniposide on the first day, the second to fourth day, once daily +pingyangmycin 4~6 mg/m2 , once daily, 3 to 12 days, 3 weeks for a course of treatment, a total of 6 courses.In the control group based on the use of thymopentin injection 20 mg and lentinan 2 mg+5% glucose solution 250 mL intravenous infusion, chemotherapy 2 d before the start, infusion 14 d, 3 weeks for a course of treatment, a total of 6 courses, for the observation group;two groups were 40 cases.The levels of serum TSGF, IgA, IgG, IgM and CD3 +, CD4 +, CD8 +, NK cells and TSGF in the two groups before and after treatment were measured.The quality of life of the patients was investigated by hospital-made questionnaires.The clinical efficacy and side effects were analyzed.Results TSGF levels in the two groups were significantly lower than that before treatment, and the TSGF level in the observation group was (39.1 ±4.9)U/mL, which was significantly lower than that in the control group (52.3 ±5.8) U/mL(P<0.05).After treatment, the TSGF level in observation group was lower than that in control group [(39.1 ±4.9) U/mL vs. (52.3 ±5.8) U/mL](P<0.05).The CD3 +, CD4 +, NK, IgG levels in observation group were higher than those in control group and the CD8 +level in observation group was lower than that in control group (P<0.05).The scores of physical symptoms, sleep quality, mental state and social affection levels in observation group were higher than those in control group(P<0.05).The total efficacy in observation group was lower than that in control group (77.5% vs.45.0%, P<0.05).The adverse reaction rate was 20.0% in the observation group, which was significantly lower than that in the control group (P<0.05).Conclusion The use of lentinan and thymopentin injection combined with PTP chemotherapy in the treatment of oral squamous cell carcinoma has higher clinical efficacy and less adverse reactions.

Objective To investigate.the survival rates in a follow-up group of patient with primary liver cancer.Methods The follow-up data of new primary liver cancer cases between year 2001-2004 in Xuhui district was investigated.The age distribution of patients was described.Survival rate was analyzed with single and multiple Cox proportional hazards regression model,respectively.Results The age proportion distribution of patients showed double apexes with one in age 45～50 and another in age 70～75.The arithmetic mean of survival month was 16.4 with 95%CI 14.8～18.1 and median month was 6.9.It was no significance between male and female.Patients who had liver operation owned longer survival time,RR=0.315 5(95%CI 0.243 2～ 0.4093).The sutdy showed 5-year survival rate was 40.90%and 3.95%for patients with or without operation,respectively.It had no significant effect on survival time by gender,age and family history.Conclusion The screening test and intervention in high-risk people shall be done preferentially before peak age,so as to find primary liver cancer earlier,and the more patients can accept a suitable surgery care,the more they can obtain longer survival time.

Objective To research on the applicational value of quantitative immunofluorescence assay of high-sensitivity C- reactive protein(HS-CRP) detection in surveillance of ankylosing spondylitis(AS) and Rheumatoid arthritis(RA).Methods Using quantitative immunofluorescence technique to detect the serum HS-CRP among 43 patients with AS and 62 patients with RA and 30 healthy controls.Results Within-run CV% of repeatability were 4.98% and3.68% for lower and higher concentration of HS- CRP,respectively;between-run CV% of the stability were 4.57% and 5.42% for lower and higher concentration of HS-CRP, respectively;There was a good correlation between results of quantitative immunofluorescence assay and BNP special protein analyzer method(r=0.997);Both the level and the positive rate of HS-CRP of patients with AS and patients with RA were higher than those of the controls in the active phase.The level and the positive rate of HS-CRP in patients with AS and patients with RA were obviously higher in the active phase than in the non-active phase(P0.05).Conclusion There were significant correlations between HS-CRP and the activity of AS and RA,So HS-CRP was useful tools for monitoring the changes of patient's condition.It doesn't have much significance in differential diagnosis of AS and RA.

Objective:To study the clinical presentation and laboratory examination data in children with hypogammaglobulinemia. It may help to study the pathogenesis early diagnosis and find the best way of treatment to save these children's life and improve their quality of life .Methods:With monoclonal antibodies detect IgG, A, M and IgG subset level in these children .With CD3 FITC ,CD4 PE, CD8 FITC ,CD19 PE as reagents, FACS was used to detect the lymphocyte subset distribution pattern ,combined with clinical observation and IVIG replacement therapy.Results:1.All these children had clinical presentation of recurrent infection ,often happened in respiratory tract and gastrointestinal tract.2.Serum IgG level was significantly reduced especially in IgG1,2,3 subsets ,10 children had B lymphocyte decrement (66.67%), only 1 case had T lymphocyte decrement,3.After screening test on the Btk gene and its protein product,these cases were dignosed:CVID 14 cases, HIM 1 case,THG 4 cases,XLA 6 cases. Conclusion:1.Hypogammaglobulinemia was one of the causes in recurrent infection, 2.It's necessary to use many high technique assays to determine the real diagnosis of hypogammaglobulinemia.3.IVIG replacement is useful for these patients,but always require such treatment in whole life span
