1.STAT3 and tumor therapeutic target
Cancer Research and Clinic 2009;21(11):789-792
STAT3, as a member of signal transducers and activators of transcription (STATs) family,which has been recognized as one of the common pathways in cancer cells. STAT3 has been found in many tumor cells that are critical to cell survival, cell proliferation, invasion, angiogenesis and immune evasion.Thus, STAT3 signaling pathway may be a potential therapeutic target for tumor metastasis.
2.Re-evaluating the relationship of serum CA125 value and prognosis in endometrial cancer
Chinese Journal of Postgraduates of Medicine 2008;31(21):20-22
Objective To investigate the role of various CA125 value in serum in instructing the treatment of endometrial cancer. Method The preoperative CA125 serum level of 147 cases of endometrisl cancer was examined by radioimmunoassay. Results Among patients with endometrial cancer, the CA125 level was higher in stages Ⅲ and Ⅳ than that in stages Ⅰ and Ⅱ (P<0.01). The sensitivity and specificity of CA125 > 20 kU/L in diagnosis of the endometrial cancer were 70.7% and 98.0%, and CA125 > 35 kU/L were 58.2% and 100.0%, respectively. The CA125 value of eases with cytological positive in abdomen was higher than that of cases with cytological negative. Conclusion The examination of CA125 serum level is valuable in the judgement of operative stages and lymph node metastasis in endometrial cancer.

International Journal of Surgery 2008;35(7):460-462
Objective To evaluate the statues of P-selectin and chang of D-dimer in vivo in patients with deep venous thrombosis(DVT)and to observe how to vary under interneving of medicines.Methods P-selectin and D-dimer of fourty patients and twenty normal subjects were fluo-rescencelabled with its corresponding monoclonal antibodies by flow cytometry(FCM)and immune method respectively.Results In the early stage,P-selectin and D-dimer of patients with DVT is higher than that in normals,and they significantly decreased in different time after patients were treated.Compared with patients who were used on-sodium ozagrel,patients used sodium ozagrel have different P-selectin(P<0.05),but D-dimer was similar(P>0.05)after fourteen days.One month later,P-selectin and D-dimer of DVT patients were lower.However,the positive rate of P-selectin of DVT was still higher than normal subjects.Conclusions The platelet has been actived in vivo in patients with DVT,so do fibrinolysis.Sodium ozagrel can decrease the action of platelet.P-selectin and D-dimmer may be used in diagnose.Post-discharge patients are still high-risk group and must be followed-up regularly.

5.Effect of different dose nerve growth factor on Fos protein expression in the spinal cord of rats with neuropathic pain
Chinese Journal of Tissue Engineering Research 2009;13(50):9866-9869
BACKGROUND: Nerve growth factor (NGF) plays a regulatory effect on survival, growth, differentiation, and egeneration of neurons. OBJECTIVE: To verify the therapy effects and the expression of Fos protein with different dose of NGF on the spinal cord of rats with neuropathic pain.DESIGN, TIME AND SETTING: The randomized controlled animal experiment was performed at the Shanghai Ninth People's Hospital.MATERIALS: A total of 72 male, health, adult, Wistar rats, weighing 180-200 g, were randomly divided into 4 groups, namely,model group and NGF with 4, 8, 16 Ijg groups, with 18 animals in each group.METHODS: All rats were prepared sciatic nerve chronic constriction injury models. Rats were intraperitoneal injected NGF with 4,8, 16 μg/(kg·d) in the experimental groups.MAIN OUTCOME MEASURES: ① Behavioral observation and mechanical pain threshold testing was performed prior to and at days 1,2, 3, 5, 7, 10, 14 after operation. ②Six of rats in each group were sacrificed at days 2, 7, and 14 after operation, and the expression of Fos protein in the spinal cord were assayed with the immunohistochemicat methods and image analysis.RESULTS: In the model group, rats raised and licked feet spontaneously after operatiOn, and the mechanical pain threshold was decreased from the 3rd day, and reached the lowest at day 14. However, in the NGF groups, rat exhibited no pontaneous pain,without subnormal period of mechanical pain threshold. The mechanical pain threshold in rats of the model group as significant different to the other groups at days 10 and 14 after operation (P < 0.05). The mechanical pain threshold in rats of all groups increased, but which of 16 μg NGF group was lower than the other groups on the first day after operation (P < 0.01 ) and lower than that of the 4 μg NGF group at 2 days after operation (P < 0.05). The expression of Fos protein in the spinal cord of the model group was increased than that of the other groups after operation (P < 0.01 ). The expression of Fos protein in the spinal cord of the 16 μg NGF group was less than that of model and 4 μg NGF groups at day 2 after operation (P < 0.01 ).CONCLUSION: NGF has therapeutical effect on neuropathic pain of rats, especially with large dosage. The mechanisms may be inhibiting the expression of Fos protein in the spinal cord of rats.

Chinese Journal of Trauma 2008;24(11):908-911
Objective To study bioactivity of microencapsulated peripheral nerve tissue after transplanted into abdominal cavity and analyze the in vivo time-effect relation. Methods Microencap-sulated peripheral nerve tissues were injected into the abdominal cavity of mice. Results Microencap-sulated peripheral nerve could remain intact six months after transplantation. The peripheral nerve cells survived, with normal proliferation function. Conclusions Microencapsulated peripheral nerve tissues can remain bioactivity at least six weeks in vivo. Improved technique of microencapsulation may prolong bioactivity of microencapsulated peripheral nerve tissues and accordingly promote nerve regeneration fol-lowing peripheral nerve injury.
8.Osteopontin and lung cancer
Cancer Research and Clinic 2008;20(7):499-502
Osteopontin (OPN), a phospborylated and glycosylated protein,is a prominent matrices component of the extracellular matrix of mineralized tissues of bones and teeth, in which they can regulate the formation and growth of hydroxyapatite crystals and influence a variety of cell activities.Recent studies have reported that the expression of OPN is not only correlated with bone formation and bone resorption but also with tumor aggression and metastasis in several types of human cancer,and OPN is even considered to be an index for the diagnosis and prognosis of tumor.This article reviews OPN's role in lung cancer' s infiltration, metastasis and prognosis.

Journal of International Oncology 2010;37(10):786-789
Burkitt's lymphoma is a highly aggressive and proliferative type of mature B cell nonHodgkin's lymphoma. Therapeutic strategies for Burkitt's lymphoma remain a challenge because of significant toxicities and poor prognosis. Further studies investigating the underlying molecular mechanisms of the carcinogenesis, chemotherapy and drug resistance are needed to improve the treatment of Burkitt's lymphoma.

Objective To investigate the effect and significance of cinobufagin on the expression of survivin of HHUA cells in the endometrial carcinoma cultured in vitro. Methods HHUA cells of endometrial carcinoma were cultured in vitro. After being intervened by cinobufagin with different concentration, the expression of survivin was measured by RT-PCR and the cellular apoptosis was tested by flow cytometry. Results In the control group: mRNA expression of survivin of HHUA cells in endometrial carcinoma was (1.22±0.23), cellular apoptutic rate was (2.31± 0.98)%; cinobufagin of 0.25 mg/ml didn't affect the survivin and cellular apoptotic rate (q=2.89, P>0.05: q=3.12, P>0.05) ; after being exposed to einobufagin of 2.5 mg/ml, the expression of survivin was (0.73± 0.26), and cellular apoptotic rate was (26.50± 6.36) %, with all of these data being different from the control group significantly (q=5.68, P<0.05; q= 10.23, P<0.05) ; the actions of cinobufagin of 25 mg/ml on mRNA expression of survivin and apoptotic rate were similar to cinobufagin of 2.5 mg/ml (q=3.49, P>0.05; q=4.35, P>0.05) . Conclusion Cinobufagin of 2.5 mg/ml inhibit the mRNA expression of survivin and proliferation of HHUA cells in endometrial carcinoma.
