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 assess the effect of anti- Helicobacter pylori (Hp) treatment on patients with chronic idiopathic thrombocytopenic purpura (cITP). Methods Fifty-nine patients with cITP and positive-Hp were divided into two groups by random digits table:Hp eradication group (30 cases,given a standard anti-Hp treatment) and placebo controlled group (29 cases,received a placebo). The platelet response of two groups was compared after three months' follow-up. Result The platelet response in Hp eradication group (63.3%, 19/30) was significantly higher than that in placebo controlled group (27.6%,8/29 )(χ2 = 7.59, P ＜ 0.05 ), and the increasing level of platelet count in Hp eradication group [ (33.5 ± 21.6)× 109/L] was higher than that in placebo controlled group [(12.6 ± 19.5) × 109/L] (t = 5.52,P ＜0.05).Conclusion Hp eradication treatment can promote the platelet recovery in mild and moderate cITP patients with positive-Hp.

According to the requirement of simulated actual combat,based on the traditional contents of sanitary reconnaissance of water source,this paper introduced some practical knowledge and skills in drinking water under emergency,including water source search,utilization,drinking principles and some measures to reduce the loss of body water.These practices enriched and consum- mated the subject of sanitary reconnaissance of water source.

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 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.
