The paper described the nature of talents with high potentials as a source of leaders,highlighting their features of uncertainty,relativity and opportunity.Authors presented their insights and experiences in developing such talents into leaders of the hospital,and hold that nurturing of such talents calls for systematic emphasis,competence models to identify them,building an environment for them to stand out,and building of an appraisal and incentive mechanism that is scientific and efficient.

The most common site of hematogenous metastasis of gastric is liver,its prognosis is bad.It is a common cause of death in patients with gastric cancer.In the past few years,along with the development of molecular biology,the mechanism of tumor metastasis has been known gradually.Tumor metastasis is multistep process,the most important condition is cell invading and angiogenesis.Here the author summarize the mechanism of cell invasion and angiogenesis.

Objective:To evaluate the changes in the transverse dimension and the perimeters of the maxillary archs produced by 3 self-ligating appliance systems during the leveling and aligning phases. Methods: 45 patients who had class I skeletal pattern and upper arch crowding 3-6 mm were divided into 3 groups with 15 subjects in every group. The dental casts were analyzed. Results: Statistically significant increases were recorded of all dentoalveolar widths (with the exception of intermolar width measured lingually) and arch perimeters. The increase in arch perimeter showed a significant negative relationship with the individual perimeter of the maxillary arch before treatment. No significant change was found in arch depth. Conclusion: The self-ligating appliance systems produce statistically significant increases in the transverse dentoalveolar width and the perimeter of the maxillary arch during the leveling and aligning phases of treatment.

Objective The levels of endothelin-1(ET-1) and calcitonin gene-related peptide(CGRP) in the plasma and cerebrospinal fluid(CSF)after acute cervical spinal cord injury. Method ET-1 and CGRP were determined by RIA in order to observe the effects of naloxone on levels of ET-1 and CGRP and neuronal death of cervical spinal cord. Result Levels of ET-1 in the plasma and cerebrospinal fluid(CSF)after acute cerical spinal cord injury increased significantly; but the levels of CGRP in the plasma and cerebrospinal fluid(CSF) decreased markedly. The levels of ET-1 in the plasma and cerebropinal fluid(CSF)decreased markedly after the threapy of naloxone; but levels of CGRP in the plama and cerebrospinal fluid(CSF)increased sinificantly. Conclusion These deta suggest that the lessening of CGRP and increasing of ET-1 may be some important reson causing death of neuron after acute cervical spinal cord injury, and naloxone can protecet cervical spinal cord neuron by increasing levels of CGRP and decreasing levels of ET-1.

ObjectiveIn order to enhance the curative resectability rate of pancreatic carcinoma. MethodsSixteen consecutive patients received an extended resection, which is referred to systemic dissection of regional lymph nodes and combined resection of the diseased PV/SMV based on traditional Whipple operation or the distal pancreatectomy. ResultsMean operation time was 8.5 hours. Mean intraoperative blood infusion was 1250mL. The procedure was considered curative in 11 (68.8 % ) and palliative in the other five. Postoperative complications occurred in 7 (43.8% ). Perioperative death occurred in one patient(6.25% ). Median length of hospital stay was 35 days. In nine patients undergoing curative resection,two cases survived for 1/2～1 year, six patients survived for 1～2 year and another patient has survived for more than 32 months without evidence of recurrence. ConclusionExtended resection for pancreatic cancer is technically feasible and two- third of pancreatic carcinoma invading PV/SMV alone can be expected to obtain curative resecetion.

Chi-pulse diagnosis is a kind of pulse diagnosis by only feeling Chi part of pulse.This method focuses on inborn Yin-yang,fire-water,and growth and decline of kidney essence,emphasizes on the physiological and pathological changes of eight extra meridians and extra viscera,clarifies and expands the content of narrow sense of yin-yang method.Chi-pulse diagnosis is prone to guided by the spot pulse feeling,do not limited by regular pulse name,and has special pulse diagnose experience and fixed knowledge of formula prescription.
