Optimization of information resources plays an important role in improving the quality of subject re-sources.Military medicine is a highly interdisciplinary subject, optimization of its information resources is thus of subject particularizes.The basic theories and practical methods for optimizing information resources were reviewed, followed by a summary of the theories and methods that can be used in optimizing the information resources in mili-tary medicine.

用秩和比法对37例脑瘫患者施行SPR术中影响应激反应的诸因素进行分析。结果显示：3—6岁小儿、切断后根小束大于50％者、电刺激量平均为5．1—10mA者、芬太尼量大于3μg／kg·h者和于腰骶部行SPR者应激反应最强。3、4级痉挛者、芬太尼量为2．1—3μg／kg·h者、7—13岁儿童、切断后根小束41—50％者和电刺激量平均大于10mA者应激反应较强。5级痉挛、14岁以上青成年和电刺激量平均小于5mA者，应激反应较弱。而芬太尼量小于2μg／kg·h、切断后根小束少于40％和行颈胸段SPR者应激反应最弱。经临床分析，作者提出：SPR中应特别注意6岁前小儿及切断后根小束超过50％的脑瘫患者的应激反应。

cases were classified by using RUGⅢ.The result indicates that RUG Ⅲ is objective to re-flect all reasonable costs for clients.It has therotical and practical significence to research RUG Ⅲ for institu-tions involving rehabilitation,family beds and deathbed care.

The theories used in construction of military medical ontology are the prerequisite of applying ontology theory to the organization of military medical knowledge, which helps to clarify the concepts in relation with the construction of military medical ontology. The current standards for military medical terms and the difficulties in construction of military medical ontology were analyzed according to the target to be achieved. The basic theories used in construction of military medical ontology were elaborated from its concepts, needs, and complexity.

An information service platform was constructed for infectious disease epidemic by standard collecting, organizing and systematizing the information of related infectious diseases, which could provide information support service for data store, knowledge share, online education and decision-making. The platform is consisted of special news module, self-developed database module, encyclopedic knowledge module and background management module, and can thus meet the needs of related persons in countries and regions along the One Belt and One Road.

Objective To select a electronic medical tag system suitable for modern war. Methods The active radio frequency identification technology was surveyed, modeled, and improved. Results It was demonstrated be tests that active radio frequency identification technology met the requirements of electronic medical tag system. Conclusion The electronic medical tag system based on radio frequency identification technology changes the traditional working mode and enhances integral capability of field first aid.

Objective To explore the way to compile a global military medical literature collection and perspectives for its research.Methods The names of military medical research institutions and their trends of development were summa-rized via semantic analysis.The collection of retrieval words for military medical research institutions( then the collection) was constructed based on expert consultation.The names of military medical research institutions were collect-ed with manual screening after retrieval withthe collection.The literature collection of military medical research institu-tions was completed with coordinated retrieved of their papers and other publications.Results According to different needs of information analysis, the literature collection of military medical research institutions could be analyzed in terms of their size, types of development, and academic authority.Conclusion Based onthe collection, the military medical research institutions collected in this article included institutions that used to be neglected during the course of information tracking of military medicine.Three kinds of institutions should be paid more attention to.The institutions were the ones with a large number of papers and citations, the ones whose papers increased or decreased dramatically, as well as the ones whose research directions were the priority fields of Chinese PLA.

Objective To investigate protective effects and mechanisms of lipoxinA4(LXA4)on human umbilical vein endothelial cells(HUVEC)under hypoxia in vitro.Methods The HUVEC culture were divided into groups as followed:added M199 cudture medium as normal contml groups,added CoCl2 to mimic hypoxia in vitro as hypoxia group and added different concentrations of LXA4(1,10,100 nmol/L)were added to the induced hypoxiai HUVEC as agents intervention group.Morphological changes of HUVEC were observed by using inverted phase contrast mieroscope.The influence of LXA4 on cell survival was investigated by methyl thiazolyl tetrazolium(MTT) assaying method after the treatment with different concentrations of LXA4 and 100 nmol/L lipoxinA4 according to different time(4,8,12 and 24 hours).The expression of von-willebrand factor (vWF) was detected by immunocytoehemistry method. The changes of cytosolic Ca2+ were measured by laser scanning confocal microscope. Results ( 1 ) Morphological changes:the cells under hypoxia lost its normal shapes and showed necrosis, while the cells cocuhured with 100 nmol/L LXA4 were normal appropriately. (2)Survival rate: the survival rates of HUVEC under hypoxia was (40. 1±3.9) % and increased to ( 52. 9 ± 1.4) %, (64. 1 ± 3. 3 ) %, ( 76. 6 ± 1.6) % respectively when added with LXA4 with concentration of 1,10, 100 nmol/L into culture medium. There was significant different survival rate when compared with that of hypoxia group. (3) The level of vWF: The expression of vWF was decreased with the increasing concentrations of LXA4 added into culture medium, the gray values were 203.9 ±0. 7 in 1 nmol/L,204.6 ±0. 9 in 10 nmoL/L,191.8 ±0. 5 in 100 nmol/L respectively, which reached statistical difference in comparison with that of hypoxia groups (P<0. 05). (4) Confocai analysis:the intracellular free Ca2+ concentrations of HUVEC were intensified with LXA4 treatment. Conclusions LXA4 plays an important role in keeping the normal shape of HUVEC under hypoxia, can enhance survival of hypoxial HUVEC and decrease the level of vWF in cytoplasm. The protective mechanism might be via decreasing mitochondria Ca2+ overload and increasing cytoplasm Ca3+ by nucleus Ca2+ transference.
