Objective To explore clinical indications and curative effects of microwave coagulation combined with submucous 5-fluorouracil (5-FU) injection in the management of early-stage lower rectal cancer. Methods Nine patients with early-stage lower rectal cancer underwent microwave coagulation with submucous 5-FU injection from January 1996 to December 2002. After the microwave treatment, a retention enteroclysis with 100~200 ml normal saline containing 1.0 g 5-FU was performed once daily for 3 days. Results In 3 patients, levels of carcinoembryonic antigen (CEA), which were preoperatively increased, were reduced below normal limits after microwave treatment. No hemorrhage or other intra- or post-operative complications was observed. Follow-up observations to January 2006 showed that all the 9 patients survived. One patient survived for 3 years and 5 months, 1 patient survived for 3 years and 8 months, and 1 patient experienced a tumor relapse at 1 year and 4 months and survived for 2 years and 9 months after a Miles procedure. Among 6 patients who survived longer than 5 years, 1 survived for 5 years and 1 month, 1 for 6 years and 3 months, 1 for 6 years and 8 months, 1 for 7 years and 6 months, and 2 for 9 years. Conclusions Surgical indications for microwave coagulation combined with submucous 5-FU injection for rectal cancer included early-stage cancer, lesions located within 7 cm away from the anus, the mass type cancer, tumor diameter at 0.5~3.0 cm or less than one third of the rectum’s circumference, well differentiated tumor, and patient’s strong anus-sparing demand. This method is minimally invasive, safe, reliable, and cost-effective.

Objective To investigate the feasibility and safety of transabdominal perposterior mediastinum radical operation in the treatment of cardiac carcinoma. Methods Twenty-six cases of cardiac carcinoma invading low esophagus underwent transabdominal posterior mediastinum radical resection. Among them 9 patients received radical proximal gastroesophagectomy, and 17 cases did radical total gastroesophagectomy. Results The procedures were all successful. The mean operation time for total gastrectomy was (189±39) min, proximal subtotal gastrectomy was (153±35) min. The averge blood loss of total gastrectomy was (200±80) ml, proximal subtotal gastrectomy was (168±76) ml. The harvest of celiac lymph nodes were (23.3±7.3), esophageal lymph nodes were (4.1±2.0). Pneumonia was complicated in 4 cases and there was no anastomotic hemorrhage, leakage nor stenosis. All patients were followed up from 5 to 51 months, liver metastasis was found in 4 cases, lung metastasis in 2 patients and death in 1. There was no anastomotic stoma tumor recurrence. Conclusion It was feasible and safe to perform transabdominal perposterior mediastinum radical operation for cardiac carcinoma patients, provided that diaphragms was not involved and tumor invaded esophageal length was less than 5 cm.

Objective: To investigate the inhibitory effects of chitosan oligosaccharide on tumor growth in vivo. Methods: Murine tumor cell line H22 was inoculated into. Then different doses of chitosan oligosaccharide were injected into the mice-bearing H22 liver carcinoma, IL-2 and IFN-? in the sera were measured by ELISA assay. The in vitro anti-proliferation activity of chitosan oligosaccharide on the lung carcinoma LH-7 cells was evaluated by MTT assay. Results: Chitosan oligosaccharide inhibited in vivo the growth of H22 tumor cells,with increasing the content of IL-2 and IFN-? in sera of the tumor-bearing mice. The weight of spleen and thymus of the mice were increased when compared with those of control group; tissue necrosis was observed in the tumor in situ; chitosan oligosaccharide also inhibited the growth of LH-7 cells in vitro. The inhibitory effect was shown in a concentration dependent pattern, but not correrlated with incubation time. The early characteristics of apoptosis of LH-7 cell could be observed under the transmission electronic microscopy. Conclusion: Chitosan oligosaccharide inhibits proliferation of tumor and improves immunity function of the hosts, and might induce apoptosis of LH-7 cells.

Objective To explore the antitumor effects and the effect of GFW on the Fas expression in spleen T-lymphocyte of the tumor-bearing mice.Methods The S180 mice sarooma model was used to detective the inhibiting effects of GFW,the Fas expression in spleen T-lymphocyte between the normal group,the model group,the GFW group and the CY group were analyzed by the flow cytometry.Results For S180 sarcoma,the inhibiting ratio of GFW is 38.93%.The protein expression of Fas showed to rise in the the model group and the CY group.There was significant difference between them and normal group(P0.05).Conclusions GFW has the antitumor function and can adjust immune through inhibitor the apoptosis of T-lymphocyte.its mechanism maybe closely related with adjusting expression levels of the Fas expression in spleen T-lymphocyte to normal.

Objective To explore the distribution and differentiation of bone mesenchymal stem cells (MSCs) in the brain of neonatal rats with hypoxic ischemic encephalopathy (HIE). Methods MSCs were isolated and purified by adhering to the culture glassware wall and prelabeled with bromodeoxyuridine (BrdU) for 72 h before transplantation. The model of HIE was established. At 24 h after hypoxic ischemia, approximate 4?10 6 cells were injected into the brain of neonatal rats with HIE through the right side bregma. The Nestin, neuron specific enolase (NSE) and glial fibrillary acid protein (GFAP) were detected by immunofluorochemistry at 4 weeks after injection. Results Majority of MSCs were distributed in the cortex, hippocampus of the lesioned hemisphere. The number of MSCs was (2781?254) in the left hemisphere, but (4708?281) in the right hemisphere. There was significant difference (t=18.70, P0.05). The expression ratio of NSE was (3.79?0.95)% in the left hemisphere, but (5.69?1.48)% in the right hemisphere (t=3.404, P0.05). Conclusion MSCs are mainly distributed in the lesioned hemisphere and can differentiate into neuronal-like cells, express the mark of neural stem cells, neurons and neuroglial cells at 28 d after intracortical transplantation.
