Laparoscopic Local Resection Based on Sentinel Node Evaluation for Early Gastric Cancer: A Preliminary Report

We previously reported that lymphatic mapping using isosulfan blue can be used to identify sentinel nodes (SNs). This study was undertaken to evaluate the feasibility of using the SN technique in treating early gastric cancer and to explore its usefulness for minimal invasive surgery. Twenty-three patients with early gastric cancer who underwent SN biopsy were retrospectively evaluated. Based on SN evaluation, individualized surgery was performed in five patients with T1N0M0 gastric cancer. When pathological examination of frozen sections revealed metastasis in SNs, we performed a standard D2 gastrectomy. Laparoscopic local resection was applied when the SN biopsy was negative. Our results showed that the success rate with SN biopsy in early gastric cancer was 100%, as were the accuracy, sensitivity, and specificity. All five patients with early gastric cancer had SNs negative for metastases both by frozen section and by postoperative pathology. Thus, all these patients underwent laparoscopic local resection without extended lymphadenectomy. We conclude that SN biopsy is a useful tool to individualize the operative procedure, and laparoscopic local resection can be safely performed using SN guidance in selected patients with early gastric cancer.     

Morphology of corticotectal cells in the primary visual cortex of hooded rats

In primary visual cortex of hooded rats, pyramidal cells in layer V may be classified as long, medium, or short, on the basis of the layer in which the apical dendrite terminates. The present study determines which of these types of pyramidal cells project to the superior colliculus. Two different strategies were used to label corticotectal cells with horseradish peroxidase (HRP). In the first set of experiments, a large number of corticotectal cells were labeled by retrograde transport following injection of HRP into the superior colliculus. In the second set of experiments, single unit recording was used to identify corticotectal cells physiologically by antidromic activation from the superior colliculus. These cells were then impaled and labeled by intracellular iontophoresis of HRP. The results from both techniques suggest that only long pyramidal cells send an axon to the superior colliculus. These cells are distinguished by an apical dendrite that extends into layer I. We conclude that in hooded rats corticotectal cells in primary visual cortex are the long pyramids in layer V.     

复方丹参注射液干扰素治疗乙肝后肝纤维化

目的探讨复方丹参注射液联合干扰素治疗慢性乙肝患者的疗效。方法110例慢性乙肝患者，按随机方法分成①对照组30例，应用普通保肝药物治疗，疗程6个月；②丹参组30例，应用复方丹参注射液（每ml含丹参、降香各1g）30ml加入10％葡萄糖溶液300ml中静脉注射1个月；③IFN组30例，应用IFN—α 3MU，隔日一次肌内注射，3个月；④联合组20例，应用复方丹参注射液30ml加10％葡萄糖溶液300ml静脉注射1个月，IFN-α 3MU，隔日一次肌内注射，3个月。丹参组，IFN组和联合组保肝药物治疗同对照组。四组病例在性别、年龄、病程，治疗前肝功能等方面均无统计学差异。治疗前检测肝功能，肝炎病毒标志，血清HA、IV—C、PCI—Ⅱ，部分病例进行肝穿病理检查。治疗开始后每月检测肝功能，3个月（治疗后）和6个月（随访时）时检测血清HA、IV—C、PCⅢ及乙肝病毒标志，治疗后1年行肝穿病理检查。结果治疗前四组患者血清HA、PCⅢ、IV—C水平无统计学差异；治疗后丹参组、IFN组、联合组血清HA、FCⅢ、IV—C水平较治疗前及对照组有不同程度的降低。结论复方丹参注射液联合IFN治疗可使血清HA、PCⅢ、IV—C有明显下降，肝组织病理改变明显改善，为目前有效的慢性乙肝治疗措施。

Local health services: some lessons from their evolution in Bolivia

Summary For a decade, numerous projects in Bolivia have tried to put in practice the concept of local health systems. But, so far, no significant changes have been made and local health services still are the 'poor relation' of the system. The main components of the project—expansion of health facilities, training of health personnel and institutional decentralization—were not designed to respond to the complexity of the problems encountered. Decentralization was implemented at the level of health districts but not accompanied by redefinition of functions at the central level, and challenged by civil servants' attempts to save their jobs. While training activities did introduce new methods and subjects, they were too often reduced to short workshops or seminars. Health facilities were built without regard for their significance beyond health care. A strategic approach is needed to adapt the planning process to the degree of liberty allowed by society.
