Taking the 8-year management practice of Sanjiu Brain Hospital of Guangdong since its founding as a case, the paper gives an account of how the hospital managed to grow by leaps and bounds. The steps taken include: guiding decision-making with innovations in thought and blazing new trails in such aspects as growth strategies, leadership structure, system of operation, quality control, nursing management, service skills, marketing management, hospital culture, and logistics management. The paper argues that innovation is the soul and driving force of hospital management and reform and that daring to and knowing how to make innovations are indispensable to enhancing the core competitiveness of the hospital and promoting its fast and sustainable growth.

Objective Telomerase reverse transcriptase (TERT) participates in pathologic processes of many ischemic damages.It also plays an important role in ischemic brain damage.There are a lot of activation mechanisms of TERT after cerebral ischemia.At present,the hypoxia-inducible factor-1 has been more clearly studied.The protective effect of TERT in ischemic brain damage may be associated with anti-apoptosis,promoting cell survival,promoting angiogenesis,and protecting mitochondria.

Hypoxia-inducible factor-1 (HIF-1) is a key transciptional regulator of cellular and systemic oxygen homeostasis,composed of the two subunits,HIF-1α and HIF-1β.HIF-1α is an inducible subunit regulated by hypoxia,which is posttranslationally modified by various ways,including ubiquitination,phosphorylation,hydroxylation,acetylation and glycation,accordingly affecting its protein's stability,nuclear translocation and regulation of its target genes.Small ubiquitin-related modifier (SUMO) is an micromolecule protein participating in posttranslational modifications of proteins dynamicly in eukaryotic organism,which is similar in structure to ubiquitin.SUMOylation and deSUMOylation are involved in multiple regulations of biologic processes,such as signal transduction,transcriptional regulation,cell cycle processes and biological rhythm.SUMOylation is related to HIF-1α stability and transcription activity in hypoxia,providing a newthread to study self-regulation mechanism of HIF-1α for us.

Objective　To study the indication, contraindication and short-term clinical effects of stereotactic radiotherapy (X-knife) in lung cancer. Methods　A total of 56 cases (Treatment group) of lung cancer were treated with X-knife composing of the modern 3-D treatment planning system and the stereotactic body frame, and SL-75 accelerator. And another 53 cases only treated with routine external radiation served as the control. In treatment group, 42 cases received 50 Gy radiation, at 2 Gy per day, 5 d per week in the upper mediastinum, hilus of lung, below the primary focus first and then underwent X-knife for the primary focuses, and other 14 recurrent and metastatic cases received irradiation of 8-12 Gy per day, 5 d by X-knife alone. Results　The actually reexamination rate for 1, 3, 6, and 12 months after X-knife treatment in 78 focuses from 56 cases was 79.5% (62/78), 89.8% (70/78), 87.2% (68/78) and 78.2% (61/78) respectively. The focuses reappeared in 3 months after the treatment and the growth rates of focus in 3, 6, and 12 month after the treatment were 2.6% (2/78), 5.1% and 9% (7/78) respectively. There were 2 focuses received a second treatment with X-knife because no change after the first one. Both the 1-and 2-year survival rates of 36 cases of the primary lung cancer in the treatment group were higher than that of control group (89.1%, 53.9% and 77.4%, 39.6%). Conclusion　The stereotactic radiotherapy is of applicable and prospective in the treatment of lung cancer. The indications include: ①As a boost dose in case when primary focus is less than 5 cm after the first external radiotherapy may reduce the exposure of lung tissue to x-ray and the occurrence of radiation pneumonia; ②Treatment for the recurrence after radiotherapy and operation; ③Radical treatment for the metastatic focus less than 5 cm. Attention must be paid to when multiple treatment is carried on the volume of the focus, the Karnofsky scores and the general condition when stereotactic radiotherapy combined with X-knife for lung cancer.

Objective Objective To investigate the clinical application of high-dose-rate(HDR)endobronchial brachytherapy for the treatment of primary lung cancer with atelectasis. Methods A total of 142 cases of lung cancer with atelectasis treated with HDR endobronchial brachytherapy and 71 cases(contr01)treated with extemal irradiation only at onr center of cancer were comparatively studied.1n the treatment group,with the aid of bmnchoscope,brachytherapy was applied 2 or 3 times at the dose of 8 Gy each time to a tissue depth of 1 to 1.5 cm.Cases in the contmlgroup,treated with external irradiation,received 60-70 Gy in total.Results Complete recruitment of atelectasis was observed in 80.28%cases of the treatment group and 64.79%in the control,T11ere Was significant difference between the two groups.Survival rates after 1,2 and 3 years in cases with complete remission of atelectasis in treatment group were 60.68%,44.44%and 23.93%,but 36.00%,28.00%and 16.00%in cases with no remission of atelectasis.Significant difference of one-year survival Was found between the two groups(P

Objective To investigate the expression of MMP-2 and MMP-7 and their elinieopathologieal significance in eoloreetal carcinomas. Methods The expression of MMP-2 mRNA, MMP-7 mRNA and MMP-2, MMP-7 in 42 samples of eoloreetal carcinomas and its adjacent normal eoloreetal mueosa were examined using fluo-rescence quantitative RT-PCR (FQ-RT-PCR) and immunohistoehemistry. The relationship of their expression with some elinieopathologieal characteristics was analyzed. Results MMP-2 mRNA, MMP-7 mRNA and MMP-2, MMP-7 were significantly over-expressed in eoloreetal carcinomas compared with its adjacent normal eoloreetal mueosa( P < 0.05 ) , and they were positively associated with bowel wall invasion, the regional lymph node metastasis and Dukes stage. The expression of MMP-2 mRNA and MMP-7 mRNA was positively correlated with MMP-2 and MMP-7 in eoloreetal eareinornas. Conclusions MMP-2 and MMP-7 may play a key role in eoloreetal carcinogenesis,tumor in-vasion and metastasis. Examination of combined MMP-2 and MMP-7 expression may have an important significance to judge the malignant degree and biological behavior of human eoloreetal carcinoma and for evaluating the progno-sis.
