RESUMO
【Objective】 To screen individuals with rare blood type of Kidd, Diego, Duffy blood group system among the voluntary blood donor in Shaanxi province and to establish on-line and physical database of rare blood type. 【Methods】 Jk(a-b-)phenotype donors were screened by 2 mol/L urea hemolysis test. Blood donors with Di(a+ b-) phenotype were screened by genotyping; Fy(a-) and D-- phenotype donors were screened by modified antiglobulin assay. 【Results】 Three cases of Jk(a-b-) phenotype were detected out of 158 484 voluntary blood donors. The distribution frequency of Jk(a-b-) phenotype was 0.019‰. Di(a+ b-) phenotype was detected in 2(0.436‰) cases out of 4 586 voluntary blood donor. Fy(a-) phenotype was detected in 8(4.034‰) cases out of 1 983 voluntary blood donors. D-- phenotype was not detected in 29 430 voluntary blood donors. 【Conclusion】 The on-line database of Kidd, Diego, Duffy blood group system had been established by large-size screening of blood donor samples, which can conclude the region′s population distribution and genetic characteristics of RBC blood group. And physical database could further be established using the technology of red blood cells cryopreservation when the conditionspermit, so as to provide the most compatible blood for the clinical effectively improve blood transfusion safety, and provide data support for blood early warning.
RESUMO
OBJECTIVE@#To observe the clinical effect of single acupoint [Yaotu (extra)] electroacupuncture (EA) therapy on lumbar intervertebral disc herniation (LIDH) and its promotion and application in community medical institutions.@*METHODS@#This research adopted a three-level promotion model, and used multi-center collaboration topics as a platform. A total of 240 patients with LIDH were divided into a group A (top three hospital, 80 cases, 3 cases dropped off), a group B (secondary hospital, 80 cases, 8 cases dropped off), and a group C (community health center, 80 cases, 7 cases dropped off). All groups were treated with EA at a single acupoint [Yaotu (extra)] under the guidance of a unified experimental protocol. The EA was given 60 min each time and performed 3 times a week for a total of 2 weeks. The changes of visual analogue scale (VAS) scores of three groups before and after each treatment were compared, and the clinical efficacy was evaluated.@*RESULTS@#Compared with before each treatment, the VAS scores of three groups after each treatment decreased (@*CONCLUSION@#The single acupoint EA therapy has a significant effect in the treatment of LIDH, can quickly relieve the pain symptoms, and has the characteristics of simple operation and easy control, suitable for promotion and application in primary hospitals.

RESUMO
Objective To explore the application of different linear evaluation methods for clinical chemistry measurement .Meth‐ods The analytical measurement ranges of clinical common items ,including alanine aminotransferase(ALT) ,creatine kinase(CK) , glucose(Glu) ,urea(Urea) and uric acid(UA) were established by using visual method ,modified Doumas method ,and according to′Guide to linearity evaluation of clinical chemistry analyzers′(health profession standard method) and Clinical and Laboratory Stand‐ards Institute(CLSI) EP6‐A document(EP6‐A method) .Results The visual method shown that the expected values and the meas‐ured values of these inspection items were probably in a straight line .The modified Doumas method shown that nonlinearity be‐tween expected values and measured values of CK was found ,but linearity was evaluated when discarding the last two points ;and the rest of inspection items all had linearity .The health profession standard method indicated that nonlinearities between expected values and measured values of CK and Urea were found ,but could not determine whether the nonlinearities of the two items were clinically acceptable ;and the rest of inspection items all had linearity .The EP6‐A method shown that linearities were directly found between expected values and measured values of ALT ,Glu and UA ,while CK and Urea had clinical acceptable linearities and linear‐ities were evaluated when discarding the maximum values .Conclusion The linearity evaluation is integrated with clinical objectives through EP6‐A document .Through setting methodology allowable deviation ,the EP6‐A method could expand the scope of accredi‐tion of linearity within the clinical acceptable range ,which has higher clinical practicability .
RESUMO
Objective To study the application of stomach tube insertion in the lateral recumbent position in rescuing the unconscious patients,to reduce the discomfort of patients and increase the one-time success rate in the insertion of stomach tube. Methods 100 cases of unconscious patients were divided into the control group and the treatment group with 50 cases in each, they adopted routine tube insertion method and tube insertion in the lateral recumbent position.The success rate of tube insertion and incidence of complications were collected and analyzed in the two groups.Results The experimental group had a higher success rate and less complications compared with the control group.Conclusions The lateral recumbent position for stomach tube insertion is the ideal position for the unconscious patients.
RESUMO
A description of the concept,origin and development,and key contents of the system safety theory,and an analysis of the presence and future of China's medical safety management,holding that such a theory enjoys a promising perspective in medical safety managemenL Medical safety management needs to follow such a theory as fl guideline,and its principles to set system safety objectives,and to determine the scope of the safety system_By building a comprehensive feedback mechanism,clarifying the responsibility borders and advocating a safety culture,medical safety management can be significantly upgraded.
RESUMO
Objective The high-pressure-vapor disinfection basket was made to take precautions against the sterile article pollution after disinfection from boiler disinfection and also for convenience. Methods Items after disinfection from 100 pots were randomly allocated to the observation group and the control group, each group had 50 pots.The observation group used the high-pressure-vapor disinfection basket to take the items from the sterilization room to the disinfection room directly. The control group used conventional disinfection cart, re-moved the items to the cart,thon took them to the disinfection room. Time cost for convey of the disinfection items was observed,and surface sampling for gormiculture was obtained from the last item conveyed to the disinfection room. Results After germiculture,2 pollution packets were found in the observation group,the polluting rate was 4%;49 pollution packets in the control group,the polluting rate was 98%,which was statistically different from that of the observation group(P<0.01). Time cost of the observation group was 8 minutes,of the control group was 13 minutes. Conclusions Use of the portable,pollution-prevention and high-pressure-vapor disinfection basket can prevent the surface of disinfection items from pollution,besides,it is convenient and costs less labor and time.

RESUMO
Objective To explore the highly effective teaching and training approaches to electrocardiogram (ECG) monitoring. Methods Using computer simulation and digital programming, ECG data-gathering platform was set up. Results Not only ECG data were gathered and stored automatically in real time, but its dynamic databases including examination database were established as well. Therefore the teaching and training approaches to ECG monitoring achieved digitization with network and multimedia. Conclusion On the basis of new computer techniques, the application study on teaching and training approaches to ECG monitoring helps to the organic integration of teaching, scientific research and clinical practice, and also helps to the improvement in the training level or quality.
RESUMO
Objective To study way of unloading and positioning of the new type medical shelter. Methods Through repeated testing and practical application, the ways of "3-lines" is used in the ground precession standardization. The first line is guard line of the left marginal of the shelter, the second is allocation line of the end part of the shelter and the third is front wheel alignment line of the whole unloading vehicles. Based on the lines, vehicles carrying shelters access to the ground in accordance with the order of three channel shelters ahead of five functional shelters. Results The real time of the shelter started is reduced to 35min, much lower than the time designed of 4h. Conclusion The application can be carried out precise positioning and improve the speed of the equipment spread.
