AIM To elucidate the possible antiarrhythmic mechanism of matrine. METHODS Whole-cell patch-clamp technique was used to record ionic currents in ventricular myocytes. RESULTS In guinea pig ventricular myocytes, matrine 100 μmol·L-1 prolonged 90% action potential duration (APD90) by 40% at a stimulation of 0.1 Hz in a frequency-independent manner, inhibited IK1 by 47% at the test potential of -120 mV, reduced IKr,tail by 50% and had no effect on IKs,tail. CONCLUSION Matrine prolonged APD through blockade of multiple potassium currents, which may relate to its antiarrhythmic efficacy.

Objective To investigate the characters of morphology change and protein expres-sion in progressed renal cell carcinoma after the treatment of sorafinib. Methods Clinical data of 2 cases with progressed renal cell carcinoma treated with sorafenib were collected. The HE slices were reviewed. Immunochemistry was used to detect the expression of Vimentin, AE1/AE3, CK7, CK8, CK18, CD10, VEGF, VEGFR2, p53 and Ki-67 levels. Results There was no difference in patho-logic type between before and after the therapy of sorafenib. Both of the 2 cases were showed degener-ation in tumor cell in different degree with fibrosis and necrosis. The expression of renal cell carcinoma related antigens (Vimentin, AE1/AE3, CK7, CK8, CK18 and CD10) had no difference before and af-ter the treatment of sorafinib. The expressions of VEGF, VEGFR2, p53 and Ki-67 were increased, and the expression of Bcl-2 was decreased after the therapy of sorafinib. Conclusions There may be some morphologie differences between the metastatic tumor or the recurrent tumor and primary tumor because of the treatment of sorafenib. However the pathologic type is the same before and after the treatment of sorafenib. The main differences are the degeneration of the tumor cell and fibrosis after the treatment of sorafenib. The expression changes of VEGF and VEGFR2 may be related to the sor-afenib application.

Objective To investigate the effect of a dual regulation of replicating adenovirus vector carrying human endostatin gene (AdTPHre-hEndo) on pancreatic cancer. Methods Human endostatin (hEndo) gene was cloned into the genome of replicating adenovirus specific for the tumor cells by virus recombination technology. The virus titer was 3.25 × 1010pfu/ml. A Balb/c nude mouse model carring sw1990 cells pancreatic cancer was established, the expression of human endostain and inhibition of tumor cells in vivo were detected. Results We successfully constructed AdTPHre-hEndo. The inhibition on pancreatic cancer cell line SW-1990 of AdTPHre-hEndo is better than Ad-hEndo (P ＜0. 01 ), and ONYX-015 ( P ＜ 0. 05 ). The endostatin expression of AdTPHre-hEndo group was significantly higher than Ad-hEndo group and the control group (P ＜ 0. 01 ). The intratumoral MVD also decreased significantly in the treated tumors(6. 8 ±2. 5 vs. 16. 0 ±4. 6、47. 2 ± 10. 0, P ＜0. 01 ). Conclusions The recombination adenovirus can express biologically active hEndo effectively, which results in inhibiting the growth of micro-blood vessels and proliferation slowly.

Chemokines are small cytokines with chemotactic activity, they are involved in regulating immune responses and inflammatory responses. In the development of tumors, chemokines are multi-functional mediators that not only affect the infiltration of immune cells into the tumor, but also have an important impact on tumor growth, angiogenesis, invasion, and metastasis. Besides, they are important targets of tumor therapy. Here we review chemokines involved in the regulation of signaling pathways, analyze the mechanism of chemokines in the development of breast cancer, summarize the chemokines targeted drugs for breast cancer in recent years and make a prospect about the role of chemokines in anti-breast cancer therapy.

Objective To evaluate the safety and efficacy of 125I radioactive seeds implantation combined with postoperative chemotherapy as a treatment option for thoracic advanced esophageal squamous cell carcinoma(ESCC). Methods A prospective cohort study was carried out between 2000and 2005. According to preoperative CT staging criteria,298 patients in phase Ⅱ-Ⅲ of ESCC, who had were admitted to Oncology Center Surgery of Nanjing First Hospital Affiliated to Nanjing Medical University and Thoracic Surgery of YanCheng Oncology Hospital, were randomly divided into three groups: intraoperative 125I seeds implantation combined with postoperative chemotherapy (group A, 98cases), postoperative chemoradiotherapy (group B, 100 cases) and surgery alone (group C, 100cases). All patients received radical resection of esophageal cancer. According to pTNM staging criteria after operation, 233 patients in phase Ⅱb-Ⅲ of ESCC were finally enrolled in the study (78 in group A, 75 in group B, and 80 in group C). With 0. 5 m Ci of single seed, total activity of 5-11 mCi and matched peripheral dose in 60-70 Gy, 10-22 125I seeds were implanted into the target of patients in group A under direct vision in accordance with treatment planning system. The validation and quality assessment of radioactive seeds were demonstrated according to CT scan or X-ray imaging. The postoperative complications were observed. The local recurrence of the cancer was demonstrated using CT scan. The survival rate of patients was followed up for 1-,3-,5- and 10 years. Results The satisfied quality assessment of 125I seeds was observed. There was no displacement or loss of seed. The local recurrence in group A, B and C was 11. 5%, 13. 3% and 38. 8%, respectively, with statistical significance (P ＜ 0. 05). There was no significant difference among three groups with respect to complications and 1-year survival (P＞0. 05). However, the overall survival rate 3-, 5- and 10-years was 64.8%,37. 7% and 25. 1% in group A respectively; 63.3%, 36.9% and 24.9% in group Brespectively; 43. 6i%, 25.0%, and 12.6% in group C, respectively (all P＜0. 05). The 3-,5- and 10-year progression free survival rates were 63.5 %, 37.4 % and 15.1% in group A respectively; 62.5 %,36.6% and 14. 4% in group B respectively; 42.5%, 25.6% and 6.2% in group C respectively (all P＜0. 05). Conclusions It is a safe, effective and simple method for intraoperative 125I seeds implantation combined with postoperative chemotherapy in treatment of advanced ESCC, which may reduce the local recurrence and improve survival rates in patients with ESCC.

BACKGROUND: Ischemic femoral head necrosis is caused by local vascular injury and blood-supply insufficiency. There exists no optimal treatment for the ischemic femoral head necrosis. Thus, the improvement of the blood supply to the femoral head seems to be a key point for the treatment. OBJECTIVE: To verify the curative effects of autologous bone marrow mesenchymal stem cell transplantation induced vascular regeneration on the improvement of ischemic femoral head necrosis via animal experiments and clinical observations. DESIGN: Contrast animal experiment and self-controlled clinical observation.SETTING: Cell Therapy Center, the 463 Hospital of Chinese PLA.MATERIALS AND PARTICIPANTS: ① Animals: Twenty Japanese white rabbits in either gender and weighing 3.0-4.0 kg were purchased from Animal Experimental Center, General Hospital of Shenyang Military Area Command of Chinese PLA. The animal experiments were coincident with the ethical standards. ② Participants: 188 patients with ischemic femoral head necrosis (335 hips) having whole following-up data were selected from Cell Therapy Center, the 463 Hospital of Chinese PLA from July 2004 to July 2007. There were 113 males and 75 females, and their ages ranged from 18 to 72 years. Diagnosis was done by using X-ray photographs, nuclide scanning, MRI and CT examinations. All patients provided the informed consent, and the study was approved by the local research ethics committee. METHODS: ① Animal experiments: The experiment was carried out at the Animal Experiment Center, General Hospital of Shenyang Military Area Command of Chinese PLA from January to June 2004. Ischemic femoral head necrosis models were established at both hindlimbs by using liquid-nitrogen refrigeration. The right side was regarded as transplantation group and the left one as control group. Mononuclear cells extracted from bone marrow were poured in the right femoral artery, while saline was poured in the left femoral artery. ②Clinical observations: Mononuclear cells were separated from autologous bone marrow of patients with ischemic femoral head necrosis after density gradient centrifugation. MAIN OUTCOME MEASURES: ①Four weeks later, angiogenesis at both femoral arteries was observed by arteriography by using digital subtraction anglography (DSA). Moreover, bilateral femoral head samples underwent pathological sections to observe bone regeneration and repair of femoral head 4 and 12 weeks later. ②Items including hip pain, walking distance and gait, abduction and internal rotation function changes of hip joint were observed in 3, 6, 12 and 24 months after stem cell transplantation in media femoral circum flex artery, lateral femoral circum flex artery and obturator artery. In 6 months after stem cell transplantation, angiogenesis and blood supply of femoral head were observed by using arteriography. In 6, 12 and 24 months after stem cell transplantation, morphological and ischemic changes of femoral head were observed by using CT, X-ray and MRI examinations. Harris scores were used to evaluate function of hip joint before and in 3, 6, 12 and 24 months after stem cell transplantation.RESULTS: Animal experiment: Twenty rabbits were involved in the final analysis. ① DSA-arteriography results: In 4 weeks after transplantation, blood-supply arteries in femoral head of right hindlimb in the transplantation group were more than those in the control group. ② Pathological results: In 12 weeks after transplantation, cartilage, lamellar bone and bone trabecula in the left femoral head were repaired remarkably, but left femoral head necrosis was not improved. Clinical observations: 188 patients were involved in the final analysis. ① Improvement of symptoms: Among 188 patients, 164 (87.3%) had remission of hip pain, 147 (78.4%) had function improvement, and 150 (80.0%) had elongation of walking distance. ② Imaging changes: At 6 months after transplantation, DSA-arteriography in 12 patients demonstrated that blood-supply arteries in femoral head were increased and thickened remarkably as compared with those before transplantation, and the blood flow was rapid. At 12-24 months after transplantation, lesion of bone matrix in 24 patients was improved under the X-ray, CT and MRI examinations. ③ Harris scores of hip joint: The scores at 6, 12 and 24 months after transplantation were significantly higher than those before transplantation (t= -3.423, -6.714, -9.039, P < 0.01).CONCLUSION: Autologous bone marrow mesenchymal stem cell transplantation can effectively improve and treat ischemic femoral head necrosis.
