Objective To understand the level of clinical first aid ability of nurses in non-emergency department of third-class general hospitals of Taiyuan City, and to provide theoretical basis for effective intervention of nursing managers. Methods A questionnaire survey was conducted among 1008 nurses in 5 third-class general hospitals in Taiyuan city. Results The total score of clinical first aid ability of the non-emergency department nurses in 5 third-class general hospitals of Taiyuan was (121.29 ± 12.19) points.There were significant differences in scores of different age, education, nursing age, grade, title and departmental nurses (F=25.584-128.611, P<0.01). There was only a difference in the theoretical knowledge reserve in different department (F=3.589, P<0.05). The effect of the first aid ability on the emergency first aid ability of the non-emergency department nurses was the energy level, the education degree and the first aid ability of the nurses are increasing with the education level and the energy level. Conclusions In clinical work, nursing managers should pay attention to the development of first aid ability of low-grade and low-educated nurses in non-emergency department, and can carry out the training for first aid and comprehensive ability by situation simulation, emergency plan exercise, process management and so on.

Objective To determine quercetin content in Polygonum chinense L.from different growing areas.Methods RP-HPLC was used to determine quercetin content.Chromatographic conditions were as follows:chromatographic column of Agilent TC-C18 (4.6 mm?250 mm,5 ?m),mobile phase consisting of methanol-0.6 %phosphoric acid (52:48),with a velocity of 1 mL?min-1,column temperature at (25?1)℃,detection wavelength being 365 nm,elution time of 20min,and an injection volume of 20 ?L.Results Standard curve regression equation of quercetin is:Y=85 355X-48.16(r=0.999 3).A good linearity was showed in the range of 0.004～0.012 mg?mL-1,with average recovery being 100.3 %,and RSD of 1.44 %.The content of quercetin in the samples from different growing areas is in the range of 183.0～848.1 ?g?g-1.Conclusions The method is simple and reliable,and can be used to control the quality of Polygonum chinense L.The existence of some differences of quercetin content between medicinal materials from different growing areas indicates that we should make a quality standard to ensure the safety and effectiveness of Polygonum chinense L.in clinic.

Objective To investigate the relationship between genetic single-nucleotide polymorphisms of ligase Ⅳ (LIG4) and heat shock protein B1 (HSPB1) and prognosis in nasopharyngeal carcinomas.Methods DNAs were extracted by phenol-chlorofrom method from peripheral blood samples of 168 nasopharyngeal carcinoma patients.Genetic single-nucleotide polymorphisms were divided by Taqman realtime polymerase chain reaction (PCR).All statistical analyses were performed with statistical product and service solutions v13.0.A p-value of less than 0.05 was confirmed as statistical significance.Single-factor and multiple-factor logistic analyses were used to calculate odds ratio (OR) and 95％ confidence interval (CI).Long-rank test and COX were also used.Results No relationship was found between the recurrence,metastasis and overall survival of nasopharyngeal carcinoma and genetic single-nucleotide polymorphisms of LIG4 and HSPB1 with single-factor and multiple-factor logistic analyses.Conclusions LIG4 rs1805388 and HSPB1 rs2868371 had no relationship with prognosis of nasopharyngeal carcinomas.

ObjectiveTo explore the effect of blocking the JAK/STAT signal pathway on the activity of Caspase-3 in the synovial tissue of rheumatoid arthritis rats.MethodsFifty rat models of collageninduced arthritis,which had arthritis index more than 2 were divided into the model group,the low dosage of AG490 group,the medium dosage of AG490 group and high dosage of AG490 group.Inaddition,6 rats were treated as normal control group.Normal saline,AG490 1,5,10 mg·kg-1 ·d-1 were given by intraperitoneal injection.Then the volume claws and pathologic scores of the rat models were recorded and the activity of Caspase-3 in the synovial tissue were compared.The results were analyzed by one-way ANOVA and LSD-t or Tamhane's T2 test.ResultsThe arthritis of the CIA models progressed fast,the volume of the claws and the pathological score of them were significantly higher than those of the control group.At the same time,no Caspase-3 positive express could be detected in the control group,whilethe model group had slightly increased expression.After different dosages of AG490 were applied,the swollen of joints was significantly improved compared with the model group.The histopathological score of the medium AG490 dosage of group and high dosage group(2.7±0.8,1.8+0.9) were remarkably decreased than those of the model group(4.3+1.2),the differences were statistically significant (P＜0.01).In addition,the Caspase-3 expression in the low,medium and high AG490 dosage group ( 1.90±0.15,3.13±0.33,3.56+0.34) was significantly higher than that of the model group(1.48±0.18)(P＜0.05 or P＜0.01 ).ConclusionBlocking JAK/STAT signal pathway can increase the activity of Caspase-3,reduce the excessive proliferation of synovial tissue,and improve arthritis symptoms.

Objective To report the HLA data of volunteer donors of Chinese bank from Northwest China and characterize the distribution of HLA genes in Northwest China. Methods HLA-A, B antigens of 2315 volunteer donors were examined by the method of microlymphocytetoxicity (MLT) test .The antigen frequencies(AF) were assessed by directly counting; and based on that gene frequencies(GF) were calculated. HLA data from other population were collected and distribution characteristics were compared. With the raw data, Hardy-Weinberg equilibrium, statistical parameters of forensic medicine interest for HLA were computed. Results A total of 18 specific antigens were detected in HLA-A and the most frequent antigen was A2 . AF and GF were 0.5136 and 0.3026, respectively. A total of 42 specific antigens were detected in HLA-B and the most frequent antigen was A13. Its AF and GF were 0.1978 and 0.1044, respectively. The heterozygosity(H), polymorphism information content(PIC), discrimination power(DP) and probability of paternity exclusion (PPE) of HLA-A were 0.8215, 0.8212, 0.9356 and 0.7798 accordingly; while H,PIC, DP and PPE of HLA-B were 0.9322, 0.9322, 0.9878 and 0.9528. Conclusion The polymorphism of HLA-A,B genes is characteristic in Chinese. In this research, the genetic trait of HLA in 2315 volunteers is consistent with Northern Han population.

OBJECTIVETo explore the better therapy in the treatment of ganglion.

METHODSNinety cases of ganglion were randomized into a two-way quintuple puncture group, a common quintuple puncture group and a fire needling group, 30 cases in each one. In the two-way quintuple puncture group, the "9-in-1" multiple penetrating needling technique was used. In the common quintuple puncture group, the traditional "5-in-1" multiple penetrating needling technique was applied. In the fire needling group, the traditional multiple fire needling technique was adopted. The treatment was given once a day, 3 treatments made one session and the efficacy was analyzed statistically after 1 session treatment in the three groups.

RESULTSAll of the three therapeutic methods achieved the efficacy on ganglion. The curative rate was 96. 7% (29/30) in the two-way quintuple puncture group, which was better obviously than 66.7% (20/30) in the common quintuple puncture group and 60. 0% (18/30) in the fire needling group (both P<0. 01).

CONCLUSIONThe two-way quintuple puncture technique achieves the remarkably superior efficacy on ganglion as compared with the common quintuple puncture technique and fire needling technique.

Objective:To investigate the pathogenic distribution of benign infantile convulsions with mild gastroenteritis(BICE)and explore the relevance of serum cytokines and BICE.Methods:Eighty BICE infants admitted in Inner Mongolia Maternal and Child Health Hospital from January 2017 to December 2019 were selected as BICE group, and 80 mild gastroenteritis infants without convulsion attack were selected as control group during the same period.Fluorometric real-time PCR was used to detect the pathogen of enterovirus.Serum cytokines including interleukin(IL)-6, tumor necrosis factor(TNF)-α, IL-8 and soluble interleukin-2 receptor(SIL-2R)were detected by using chemiluminescence method.The relevance of frequency and duration of convulsion in infants with BICE and the indicators above were analyzed.Results:Rotavirus infection was the main cause of BICE during the study period in this region.Among 80 cases in the BICE group, rotavirus positive infants accounted for 38.8%(31/80) and norovirus positive infants accounted for 10.0%(8/80). The levels of IL-6, IL-8 and SIL-2R in the BICE group were prominently higher than those in the control group( P<0.05); the difference of TNF-α level between two groups had no statistical significance( P>0.05). The levels of IL-6, TNF -α, IL-8, SIL-2R in the group with convulsion attack times ≥ 2 and convulsion duration ≥5 min were higher than those in the group with convulsion attack times<2 and convulsion duration<5 min( P<0.05). The frequency and duration of convulsions were positively correlated with the levels of IL-6, TNF -α, IL-8 and SIL-2R( P<0.05). Conclusion:Rotavirus is the main pathogen of BICE in this region.There is immunologic imbalance in children with BICE, especially the changes of IL-6 and SIL-2R levels, which may provide effective cytological and experimental data evidence for judging progression and prognosis of the disease.
