Key words are important parts of scientific and technical articles, correctly indexing can fully reveal the core content and improve the effective communication as well as application of academic articles. Furthermore, key words are the chief indexes for measuring journal quality. In this article, we took Chinese Journal of Medical Imaging as example, deeply explored the characteristics, indexing principles and methods of journal articles in radiological imaging.

Objective To Investigate the application value of strong ion gap(SIG),anion gap(AG)and other four indicators in the trauma disease.Methods Blood was taken from trauma patients admitted to hospital immediately,with the heparin anticoagulation,misce bene.Blood gas was measured.Creatinine(Cr),phosphorus and albumin(ALB)was measured simultaneously.Results Betwean traumatic group and control group,there was signifrcant difference in SIG,AG,potential HCO3-,and other 5 item(P4mmol/L.

Objective To evaluate the early kindney injury by means of urinary protein/creatinine ratio(TPCR,200mg/g Cr)through group-discrimination in mellitus diabetes patients. Methods Qualitative analysis was carried out with urine 5~6 item indexes in 113 cases of diabetes mellitus ,61 cases of heallthy people and other 67 cases of diabetes mellitus patients. 2 groups were divided by means of urinary protein/creatinine ratio(TPCR,200mg/g Cr).Results In 113 cases of diabetes mellitus ,urine TPCR,mAlb,?2-MG,LAP and AFU of 38 cases in TPCR≥200mg/g Cr group were significantly higher than those of 75 cases in TPCR

Objective To explore the effect of using hydrochloricde lidocaine plasmagel in the urethral catheterization of male patients.Methods Divided 103 patients into the experimental group and the control group randomly.There were 53 cases in the experimental group and using hydrochloricde lidocaine plasmagel for the urethral catheterization.There were 50 cases in the control group and using the traditional paraff in urethral catheterization.Evaluated the pain degree of patients by VAS,and then monitored the blood press and the heart rate at the same time.Results There was a significant difference between these 2 groups in the VAS,P0.05.Conclusion Using hydrochloricde lidocaine plasmagel in the urethral catheterization of male patients is an effective method to alleviate the pain of patients and then decrease the incidence rate of complication.

Objective To study the expression of the fibronectin (FN) and ? 1 integrin (? 1) in epiretinal membranes(ERM) of eyes with proliferative vitreoretinopathy(PVR). Methods Twenty epiretinal membranes were obtained from eyes undergone vitrectomy for retinal detachment complicated with PVR and observed by immunohistochemical methods. Results Overexpression of FN and ? 1 were observed in 18 and 16 membranes respectively. Conclusion The synergism of FN and ? 1 in their action mignt be one of the important roles in the development of PVR.

Objective To analyze the characteristics of balance impairment in stroke patients over 60 years old. Methods This was a retrospectivecase-control study. Subjects were divided into two groups, normal control group and stroke group. Tetrax Interactive Balance Systemwas used to examine stability index (ST), weight distribution percentages, weight distribution index (WDI), fall index (FI), synchronizationsand spectrum analysis of postural sway under the condition of standing still with eyes open respectively in both groups. Results Frequenciesof spectrum analysis of postural sway in the stroke group were significantly higher than that in normal control group (P<0.05) exceptthe low frequencies. The weight distribution percentages of unaffected foot and WDI of the stroke group were significantly higher thanthe normal control group (P<0.05). ST and synchronizations in the stroke group were worse than the normal control group (P<0.05). In thestroke group, correlations were found between FI and ST, FI and spectrum analysis of postural sway (except the low frequencies), as well asbetween FI and synchronizations (P<0.05). Conclusion Stability index, weight distribution percentages, weight distribution index, synchronizationsand spectrum analysis of postural sway are significantly abnormal in the elderly stroke patients with balance impairment. And theirfall index was found to be correlated to a variety of factors.

OBJECTIVE To investigate the method of quality control on the whole process in sterilization supply department. METHODS According to issued by Ministry of Health all kinds of criteria and inspections,the whole process in sterilization supply department was analyzed,and then the quality was controlled. RESULTS The whole process of sterilization was standardized,systematized and programmed. CONCLUSIONS The quality control on the whole process is an effective measure to ensure the rate of supply eligibility and support.

Objective To investigate the human resources of neurosurgery intensive care unit(NICU)using modified nursing activity score(NAS).Methods NAS was used to investigate the nursing work load of all shifts and compute the needed personnel for every shift,followed by adaption of nursing staff based on the results.Results Based on the scores by NAS,day shift was the heaviest in work load,followed by early night shift and then by late night shift.The differences between day shit and early night shift or late night one were both statistically different(P<0.05 for both).Conclusions The adjustment based on the results by NAS will reduce nursing risk and improve quality of nursing.

Objective To evaluate the value of three dimensional reconstruction images of rotational DSA on measuring aneurysmal necks and make a comparison with traditional DSA so as to provide more abundant and accurate informations for the enbolization of aneurysm. Methods A comparison was made between the measurement of aneurismal necks from 14 cases with traditional DSA examination and a measurement made on three dimensional reconstruction images of the same patient. Results There was a difference shown in the measurment of the aneurysmal necks between three dimensional reconstruction images of rotational DSA and those of traditional DSA, outcoming with more angles and data on three dimensional reconstruction images. Conclusions There are more angles of aneurysmal neck can be shown on rotational 3D DSA especially for the demonstration of the largest aneurysmal neck with a directional value for the intervention.

Objective :To study the effects of intercellular adhesion molecule-1 (ICAM-1) and human leukocyte antigen (HAL-DR) on the immunopathologic process of uveitis. Methods:Imn- munohistochemical techniques were applied to detect their expression in eyes of both the health (20 cases from eye bank) and patients with uveitis (54 cases with 54 eyes which included 33 ex- ogenous uveitis and 21 endogenous one). Results:Both the two ant igens were detectable in the choroidal and retinal tissues in eyes of uveitis while all the normal eyes showed negative expres- sion of ICAM-1 and negative or little expression of HLA-DR (P＜0. 01). However,there was no statistically significant difference between exogenous and endogenous types (P＞0. 05). Conclu- sion: Both ICAM-1 and HLA-DR may be responsible for cell recognition and binding in the in- flarnmatory tissues. The co-expression of ICAM-1 and HAL-DR showed that these two factors might play an important role in the immunologic damage of the choroid and retina in uveitis.
