Objective To apply the personal digital assistant(PDA)scanning positioning two-dimensional code recognition technology in writing nursing records in patients with acute ischemic stroke treated with intravenous thrombolysis,and to evaluate the application effect.Methods The quasi-experimental design was conducted.The nursing records routinely written by emergency nurses using mobile nursing cart for 58 patients with acute ischemic stroke treated with intravenous thrombolysis admitted to department of emergency of Zhejiang Hospital from September 2021 to February 2022 was taken as the control group,and the nursing records written by emergency nurses using PDA for 51 patients with acute ischemic stroke treated with intravenous thrombolysis from March 2022 to August 2022 through scanning positioning two-dimensional code recognition technology was used as the observation group.The differences of time required for writing nursing records and the incidence of errors in nursing records were compared between the two groups,and the satisfaction of emergency nurses in the observation group using PDA scanning positioning two-dimensional code to write nursing records was evaluated.Results The time required for writing nursing records in the observation group was significantly shorter than that in the control group[seconds:137(109,192)vs.480(436,604),P<0.05],the incidence of inadequate records of the first course of specialist assessment[3.92％(2/51)vs.20.69％(12/58)],and the incidence of insufficiently detailed records of thrombolytic observations[7.84％(4/51)vs.43.10％(25/58)]were significantly lower than the control group(both P<0.05).The differences between the observation group and the control group were not statistically significant when comparing the incidence of irregularities in thrombolytic drug pump records[0％(0/51)vs.1.72％(1/58)],incidence of irregularities in muscle strength assessment records[1.96％(1/51)vs.5.17％(3/58)],and the occurrence of typos in the nursing records[0％(0/51)vs.3.44％(2/58),all P>0.05].In addition,the overall satisfaction of emergency nurses in the observation group using PDA scanning positioning two-dimensional code to write nursing records was 92.94％(2 844/3 060),and the average score of each item in the synchronous nursing record of the positioning two-dimensional code was>4.5 points,among which the satisfaction score of ease of operation was(4.78±0.50),the acceptance of emergency nurses using PDA scanning positioning two-dimensional code to write nursing records was good,and could meet the clinical needs.Conclusion Using PDA scanning positioning two-dimensional code assists the writing of nursing records in the stroke treatment process,shortens the time required for writing nursing records of emergency nurses,reduces the incidence of errors in nursing records,and improves the quality of nursing records;At the same time,for emergency nurses,it can effectively reduce the burden of writing nursing records and improve their satisfaction with nursing records,which is worthy of clinical promotion.

Objective To discuss the value of high frequency ultrasound for the evaluation of subclinical rheumatoid arthritis.Methods Forty-four rheumatoid arthritis patientswho reached disease activity score (DAS28) clinical remis-sion were included.Ultrasound assess were carried out in all 68 joints,including bilateral temporomandibular joints,sternoclavicular joint,acromioclavicular joint,shoulder joint,elbow joint,wrist joint,1-5 metacarpophalangeal joints and the interphalangeal joint of the thumb,the 2-5 proximal interphalangeal joints,the 2-5 distal interphalangeal joints,hip,knee joint,ankle joint,tarsus joint,the 1-5 metatarsophalangeal joint,1-5 toeinterphalangeal joints.Analysis for the correlation between PD,GS score and gender,age,course of disease and clinical disease activity index were conducted.The pain visual analogue scale (VAS),time of morning stiffness,swollen joint count (SJC) and tender joint count (TJC),health assessment questionnaire (HAQ) score,erythrocyte sedimentation rate (ESR),and C-reactive protein (CRP) and rheumatoid factor (RF),anti cyclic citrullinated peptide (anti CCP) antibody,simplified disease activity index (SDAI),DAS28-CRP,DAS28-ESR were compared.Using Pearson and Spearman to analyze ultrasonic joint synovitis index score and clinical indexes,Student's t-test was employed to assess the significance of difference between two independent sample.Results Twenty-six patients reached/European League against Rheumatism (ACR/EULAR) 2011 remission,19 patients achieved ACR remission,and 3 patients achieved ultrasound remission.There was correlation between GS score and the course of disease and the number of swollen joints (r=0.602,0.470,P＜0.01).There was a positive correlation between ultrasound PD score and the patient's pain score,the total score of patients,ACR/EULAR2011,DAS28-ESR,DAS28-CRP (r=0.323,0.337,0.329,0.360,0.343,P＜0.05).The ultrasound PD score also had a positive correlation with CRP,ESR,time of morning stiffness (r=0.474,0.490,0.415,P＜0.01).Conclusion The subclinical arthrosynovitis can be detected by high frequency ultrasound in most rheumatoid arthritis patients at clinical remission.The PD ultrasound has advantage in evaluating RA activity over GS ultrasound.

OBJECTIVE:Allele frequencies and forensic parameters for six miniSTR loci(D10S1248,D14S1434,D22S1045,D4S2364,D2S441 and D1S1677)were analyzed in a population of 173 unrelated Chinese Han population individuals from Northeast China.METHODS:The six miniSTR loci were preformed in two multiplex fluorescent PCR systems.ABI 310 Genetic Analyzer was utilized in capillary electrophoresis and the lengths of allele fragments were analyzed.Genetic data collection and analysis software were used for data collection and genotyping.Statistical analysis was performed to the data.RESULTS:The six miniSTR loci showed a moderate degree of polymorphism in Han population from Northeast China.The observed allele sizes were from 67 bp to 115 bp,and the observed heterozygosity ranged from 0.728 to 0.827.The combined power of discrimination and the combined power of exclusion for the six miniSTR loci in Northeast China were 0.999 99,and 0.993 31,respectively.CONCLUSION:The six miniSTR showed a moderate genetic polymorphism in Han population from northeast of China.Due to their small size of PCR amplicon,the six miniSTR could be useful supplements to the CODIS STRs,and they would be useful in population genetics and forensic analysis.
