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 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 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 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.

BACKGROUND:Brain microvascular endothelial cel s (BMECs) are important tools in the field of neuroscience research;therefore, how to obtain highly purified BMECs is a key and difficulty in vitro.
OBJECTIVE:To develop a simple method of isolating and culturing highly purified BMECs.
METHODS:C57BL/6 mice aged 6-8 weeks old were selected, and microvessels were obtained using enzyme digestion and gradient centrifugation. Further, endothelia cel s were purified by certain drugs, fol owed by identified by CD31 and GFAP immunofluorescence staining. The expression of Claudin-5 was detected using immunofluorescence staining with anti-Claudin-5 antibody.
RESULTS AND CONCLUSION:Mouse BMECs grew and arranged in spiral or cobblestone-like. Immunofluorescence staining showed that the purity of BMECs reached above 99%and Claudin-5 was highly expressed. In conclusion, a simple method of easy accessibility is developed to obtain highly purified primary mouse BMECs.

Objective To investigate and analyze cognitive similarities and differences of nurses factors that lead to the tense nurse-patient relationship from both attitudes of nurses and patients. Methods By using the method of questionnaire, 284 nurses and 305 patients were investigated respectively in a top'three hospital of a city. Results There was a significant difference in cognitive scores of nurses factors that lead to the tense nurse- patient relationship (P < 0.01), patients' scores were (3.90±0.47) points which were higher than (3.52±0.35) points of the nurses′. In dimensions of prioritization, both nurses and patients believed that technical ability, professional knowledge and service attitude were the main factors leading to the tense relationship between nurses and patients. While nurses held that communication ability was more important, patients held that the nurse′s own personality was more important. Conclusions There are similarities and differences of attitudes to nurs's factors between nurses and patients regarding tension in nurse- patient relationship. The tense relationship between nurses and patients is affected to a great extent by nurses' professional knowledge, technical ability and service attitude. Managers should objectively evaluate and fully pay attention to cognitive similarities and differences of both sides, strengthen nurses′theoretical knowledge and clinical skills training, improve service attitude, and develop good character,in order to provide high quality nursing service for patients.

Thanks to the three decades of reform and opening up,hospitals in China have made tremendous achievements in their development,yet facing new ehallenges as well.to address these challenges,there is an urgent need for these hospitals to further their reform under the guideline of the scientific concept of development.This will help them strengthen their hospital culture,quality control,technology,human resources development,and their leadership,in order to achieve a better and faster growth,better serving the role to build a harmonious socialist society.
