Autophagy is a classical regulatory mechanism of energy metabolism and self-update system in the maintenance of the intracellular homeostasis and cell development. Autophagy has been recently found to play a role in tumor development. Autophagy regulates tumor formation, proliferation, metastasis, and metabolism. At the same time, the anticancer drugs formed with autophagic mediators have been used in the treatment, which suggested that improving autophagy activity to inhibit tumor has become a new way for cancer treatment of cancer patients. This article gives an overview of the regulatory mechanism of autophagy, the relationship between autophagy and tumor, and tumor therapy by targeting autophagy.

Objective We aimed to discuss the influence of establishment of a hospital which makes people satisfied on nursing management. Methods We improved our nursing work by establishing quality-control groups, training staff, checking once a week and making feedback once a month through decomposing and subdividing the standard of building a hospital which makes people satisfied from March 2002 to December 2006. Results The qualified rate of nursing management increased from 69.3% to 97.6% every year, which has statistical difference (P<0.01). Conclusions Establishment of a hospital which makes people satisfied improved the general level of nursing management quality and nursing staff. We acquired good social and economic befenit.

Objective To investigate the morphological change of intratumoral microvessels after administration of thalidomide in the murine hepatic metastases. Methods Among 20 mice with hepatic metastases created by injection of colon-26 tumor cells into the spleen, 10 were treated with thalidomide (200 mg/kg) by intraperitoneal injection daily, the other 10 were treated with saline only by intraperitoneal injection daily. Fifteen days after inoculation of tumor cell, the intratumoral mierovessel of hepatic metastases with similar size in both groups were studied with in vivo microscopy (26 and 27 neoplasms in experimental group and control group respectively ) and immunohistochemistry for CD34 (52 and 55 neoplasms in experimental group and control group respectively). Two-tailed student t test was used to determine differences in intratumoral microvessel density (MVD), intratumoral branch density (BD) and CD34 positive intratumoral microvessel density (MVD-CD34) between the small ( < 400 μm in diameter) and large metastases in both groups, and that between thalidomide treated group and control group. Results For the control group, although the MVD and MVD-CD34 of larger metastases was more than that of small metastases respectively [(18.1±3.5)% vs (13.0±3.2) %, t =2.840,P<0.01;(22.9±2.8)vs ( 12. 8±2. 5) vessels per field, t = 9. 860, P < 0. 01 ], the BD was similar to that of small metastases [(110.0±20.5)vs(99.7±17.3) branches/rnm2, t = 1.040,P >0.05]. For the thalidomide treated group, despite the MVD-CD34 of larger metastases was more than that of small metastases [ ( 17.4±2. 3)vs (11.5±2. 5 ) vessels per field, t = 8. 770, P < 0. 01], the MVD and BD was similar to that of small metastases respectively [(14.7±3.5)% vs(13.2±3.3) %, t =0.826,P >0.05; (95.3±18.3)vs (97. 1±21. 0)branches/mm2,t=0. 347,P>0. 05]. The MVD, BD and MVD-CD34 of small metastases were similar to each other between two groups ( t = 0. 098, 0. 392,1. 190; P > 0. 05 ), however, that of large metastases were significantly lower in thalidomide treated group than in control group ( t = 3. 140,2. 870, 9. 850;P < 0. 01 ). Conclusions Thalidomide exerts antiangiogenic effect on the hepatic metastases with angiogenesis only, and the different vascular components in the tumor vasculature demonstrate variousresponses to antiangiogenic therapy.

Objective To search for a scientific and feasible system for performance appraisal of hospital management staff, and enhance the level of hospital management. Methods The 360-degree evaluation and improved performance report evaluation are called into play to examine such staff. Examiners include the superiors, peers (heads of clinical and technical departments and those of administrative departments), inferiors and others (representatives of the faculty congress and staff congress). Results Outcomes of the two evaluation methods found 8 of the top ten as overlapping, and 8 of the bottom ten as overlapping as well. 80% overlapping between the two prove the results as highly similar, and a relativity analysis found the general results of the two methods as highly consistent. Conclusion United applic of the two methods can effectively examine the management staff and improve their management capabilities.
