Objective To observe the change of vascular endothelial cells and structure of the auricular posterior vein caused by freezing or pingyangmycin injection alone and freezing in combination with pingyangmycin injection,to investigate the effect of these treatments on the vein. Methods Eighteen rabbits were divided into 3 groups of 6 each, and another rabbit was used as a control. (Pingyangmycin) was injected into the auricular posterior vein in the first group, spray freezing within 20 seconds on the auricular posterior vein was performed in the second group,and freezing in combination with pingyangmycin injection was performed in the third group. Light microscope and transmission electron microscope were used to observe the change of auricular posterior vein in the rabbits.Results Proliferation of endothelial cells,and thickening of vessel wall were induced by pingyangmycin. Thrombus formation, tissue oedema and inflammatory infiltration induced by spray freezing within 20 seconds were reversible. Thrombus formation, proliferation of endothelial cells and thickening of the vessel wall was induced by freezing in combination with pingyangmycin injection.Conclusion Freezing and pingyangmycin injection have the synergistic effect, resulting in the proliferation of endothelial cells, thrombus formation, thickening of vessel wall, and even occlusion of vessels.

Objective To analyze the correlation between Glasgow coma score(GCS),blood lactic acid(Lac),and blood transfusion volume in traumatic emergency hemorrhagic shock patients,and their predictive value for patient prognosis.Methods Retrospective collection of clinical data from 128 trauma emergency shock patients who were treated and followed up in the Emergency Medical Center,Jinhua People's Hospital from March 2021 to May 2023.They were divided into good prognosis group(n=106)and poor prognosis group(n=22)according to their prognosis.The general information,GCS score,Lac level,and blood transfusion volume of two groups were compared.Using Cox regression model to analyze the influencing factors of prognosis in trauma emergency hemorrhagic shock patients.Establish receiver operating characteristic(ROC)curve to analyze the predictive value of GCS score,Lac level,and blood transfusion volume on the prognosis of trauma emergency hemorrhagic shock patients.Results Among 128 patients,22 had poor prognosis,accounting for 17.19％.The initial 24-hour blood transfusion volume,Lac,and white blood cell(WBC)in poor prognosis group were higher than those in good prognosis group,while the admission GCS score and hemoglobin(Hb)level were lower than those in good prognosis group,and the differences were statistically significant(P＜0.05).Pearson correlation analysis showed that the initial 24-hour blood transfusion volume was negatively correlated with admission GCS score and admission Hb level(P＜0.05),and positively correlated with admission Lac level(P＜0.05).The initial 24-hour blood transfusion volume,admission GCS score,admission Lac,and admission Hb levels are all independent risk factors affecting the prognosis of trauma emergency hemorrhagic shock patients(P＜0.05).The initial 24-hour blood transfusion volume,admission GCS score,admission Lac,admission Hb level,and combined predicted area under the curve(AUC)were 0.722,0.872,0.881,0.798,and 0.931,respectively,with sensitivity of 68.2％,76.6％,85.7％,75.7％,and 88.8％,and specificity of 70.8％,81.0％,78.5％,81.0％,and 85.7％,respectively.Paired Z-tests showed that the combined AUC was higher than a single indicator,and both sensitivity and specificity were optimal(P＜0.05).Conclusion The initial 24-hour blood transfusion volume,admission GCS score,admission Lac,and admission Hb levels are all independent risk factors for poor prognosis in trauma emergency hemorrhagic shock patients,and the combined prediction of the four has the highest efficacy value.

Background: Classical swine fever virus (CSFV), the causative agent of classical swine fever (CFS), is a highly contagious disease that poses a serious threat to Chinese pig populations. Objectives: Many provinces of China, such as Shandong, Henan, Hebei, Heilongjiang, and Liaoning provinces, have reported epidemics of CSFV, while the references to the epidemic of CSFV in Yunnan province are rare. This study examined the epidemic characteristics of the CSFV in Yunnan province. Methods: In this study, 326 tissue samples were collected from different regions in Yunnan province from 2015 to 2021. A reverse transcription-polymerase chain reaction (RT-PCR), sequences analysis, and phylogenetic analysis were performed for the pathogenic detection and analysis of these 326 clinical specimens. Results: Approximately 3.37% (11/326) of specimens tested positive for the CSFV by RTPCR, which is lower than that of other regions of China. Sequence analysis of the partial E2 sequences of eleven CSFV strains showed that they shared 89.0–100.0% nucleotide (nt) and 95.0–100.0% amino acid (aa) homology, respectively. Phylogenetic analysis showed that these novel isolates belonged to the subgenotypes 2.1c and 2.1d, with subgenotype 2.1c being predominant. Conclusions The CSFV was sporadic in China’s Yunnan province from 2015 to 2021. Both 2.1c and 2.1d subgenotypes were found in this region, but 2.1c was dominant.

Objective To analyse the effect on implementation of the International Guidelines for Clinical Treatment of Pressure Injuries within leadership-staff-performance improvement-information technology(LSPI)framework of quality improvement,therefore to provide theoretical insights in promoting the transformation of prevention and treatment practice guidelines to clinical practices.Methods A pre-and post-control study was in this study.A total of 101 005 inpatients admitted to our hospital between July 2019 and June 2020 were assigned to a control group,and the other 110 824 patients who were hospitalised between July 2020 and June 2021 were assigned to a trial group.The two groups were compared in terms of the promptness rate and accuracy of primary risk assessment,response rate of high-risk patients and incidence of pressure injury before and after implementation of the guideline.Results After implementation of the guideline,the promptness rate and the accuracy of primary risk assessment and the rate of preventive measures in high-risk patients increased from 86.73%to 96.25%,93.46%to 98.69%and 94.21%to 98.15%,respectively.The incidence of hospital pressure injury decreased from 0.77‰ to 0.29 ‰.All the differences were statistically significant(all P＜0.05).Conclusions Implementation of the International Guidelines for the Clinical Treatment of Pressure Injuries within the LSPI framework of quality improvement can improve the quality of process management in pressure injury and reduce the incidence of pressure injuries.Therefore,it can facilitate the guideline-based code of practice in the clinical practices.

Objective To establish new classification criteria for early rheumatoid arthritis (E-RA) based on large samples of early inflammatory arthritis patients and to evaluate the value of this criteria in China.Methods Patients who had arthritic complaints with disease duration less than one year were enrolled.They were divided into RA group and non-RA group according to the clinical diagnosis by experienced rheumatologists.The clinical and laboratory parameters were analyzed and those with high sensitivity or specificity were selected as the new classification criteria.Statistical analysis was carried out by using t test,x2 test and Logistic regression.Results ① A total of 803 patients with early inflammatory arthritis were included in this study.Five hundreds and fourteen patients were diagnosed as early RA and 251 were diagnosed as other rheumatic diseases,and the diagnosis of 38 patients remained unestablished by the end of follow-up.② New E-RA classification criteria were established based on the parameters with high sensitivity and/or specificity.The sensitivity of the new E-RA criteria was 84.4％,which was higher than 1987 ACR criteria (58.0％),while the corresponding specificities were similar,which were 87.4％ and 93.6％ respectively.③ Compared with the complex scoring system of 2010 ACR/EULAR criteria,the E-RA criteria was more simple and practical.The diagnostic sensitivity and specificity of E-RA criteria were higher than those of 2010 ACR/EULAR criteria reported in the literatures.④ New classification criteria based on scoring system using Logistic regression analysis was established.The sensitivity of this criteria was 86.4％,which was higher than 1987 ACR criteria (58.0％).Conclusion The diagnostic value of the E-RA criteria developed in this study for early RA is better than 1987 ACR criteria,and is more simple than 2010 ACR/EULAR criteria.It may be used as a new classification criteria for early RA diagnosis.
