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 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.

This study was aimed to explore the resource diversity and microbial inhibition activity of endophytic fungi from medicinal plant Plantago asiatica L. The endophytic fungi were isolated from the root, stem and leaf of the host by tissue inoculation culture and five plant pathogenic fungi and four bacteria strains used as indicating microbes to test microbial inhibition activity by agar plate antagonistic action and modified agar gel diffusion methods. The results indicated that thirteen fungal endophytic strains were isolated from the host. Most of them came from stem, then leaf, and root as the least in number. The isolated strains attribute to five genera, two fam-ilies, and two orders based on morphological characteristics. For the isolated strains, eleven of them were found to have some microbial inhibition activities against one or more indicating fungi, making up 84.6% of the total iso-lates. Six isolated strains had some antimicrobial activities against one or more indicating bacteria, amounting to 46.2% of the total isolates. Three isolated active strains, which are PAEFS001, PAEFS007 and PAEFS008, ex-hibited evident inhibition activities against five kinds of pathogenic fungi used in the trials respectively. The strain of PAEFS001 ascribed to Ozonium sp. Both strains of PAEFS007 and PAEFS008 ascribed to Aspergillus sp. One active strain of PAEFS003 showed evident antibacterial activities to Bacillus subtilis and Staphyloccus aureus, which belonged to Fusidium sp. The endophytic fungi from medicinal plant Plantago asiatica L. have evident an-timicrobial activities. Their inhibition activities against pathogenic fungi have relatively broad spectrum. And their inhibition activities to both Bacillus subtilis and Staphyloccus aureus as G+ are evident and have certain selectivi-ty. It is feasible to find new bioactive compounds associated with endophytic fungi from Plantago asiatica L. Fur-ther research and development of the endophyic fungi will be important for the integrated utilization of the host.
