Porcine reproductive and respiratory syndrome virus (PRRSV) has been recognized as one of the most important pathogens of pigs throughout the world. In 2006, more than 10 provinces of China have experienced an epizootic outbreak of pig diseases characterized by high fever, reddened skin and high morbidity and mortality. From June 2006 to April 2007, we have investigated some clinical samples in Hubei province by RT-PCR and cloned several major genes, N, GP5 and NSP2 gene, shown in this study. Phylogenetic analysis of these genes revealed that the highly pathogenic PRRSV variant, ZB, was responsible for 2006 emergent outbreak of pig disease in Hubei province similar with those variants isolated from other provinces in China in 2006, and belongs to the NA-type PRRSV. In the PRRSV variants, the N and GP5 shear about 90% identity with prototypic ATCC VR-2332 and some typical NA-type Chinese isolates, except the 2850bp NSP2 gene (only shares 65% identity with ATCC VR-2332). But they all shear more than and 97% identity with other highly pathogenetic Chinese PRRSV strains. Additionally, there are extensive amino acid (aa) mutations in the GP5 protein and 2 deletions in the Nsp2 protein when compared with the previous isolates. Most of the variants found in 2006 epizootic outbreak of pig diseases in China were the farthest variants from the typical NA-type PRRSV in phylogenetic distance, and these diversities may be responsible for the differences in the pathogenicity observed between these variants and original Chinese PRRSV strains.

Objective To explore the application effects of clinical nursing pathway on recovery of upper-extremity functions during different stages after surgery of breast tumor. Methods A total of 120 patients who received the surgery of breast tumor in our hospital from January 2012 to December 2013 were selected as research subjects. They were randomly assigned to a research group and a regular group according to the method of random number table, with 60 in each. The regular group was given clinical regular nursing for the recovery of upper-extremity functions after the surgery, and the research group was given clinical nursing pathway for the recovery of upper-extremity functions after the surgery. Nursing effects were observed between the two groups. Results Arms bending forward and arms bending inward as well as abduction and rotation in the research group were significantly better than those in the regular group, and the differences were statistically significant (P<0.05). Satisfaction rate on clinical nursing in the research group was 93.3%, higher than that of 75.0%in the regular group(P<0.05). Life quality score in the research group was(56.1±5.9), significantly higher than that of(43.8±6.3)in the regular group, and the difference was statistically significant(P<0.05). Conclusion Clinical nursing pathway is feasible clinically for the recovery of upper-extremity functions during different stages after the surgery of breast tumor. It promotes the recovery of upper-extremity functions, as well as en-hances satisfaction rate on clinical nursing and life quality, which is worthy of clinical application.

Objective:To study the expression and clinical significance of microRNA-574-3p (miR-574-3p) in colon cancer.Methods:A total of 106 colon cancer patients who were admitted to the First Hospital of Qinhuangdao and Shijiazhuang Hospital of Traditional Chinese Medicine from June 2012 to June 2015 were selected as the research objects. Real-time fluorescent quantitative polymerase chain reaction (qRT-PCR) was used to detect the expression level of miR-574-3p in colon cancer tissues and normal adjacent tissues. The relationship between the expression of miR-574-3p and the clinicopathological characteristics and prognosis of patients with colon cancer was analyzed. Immunohistochemical staining was used to detect the relationship between the expression of miR-574-3p and the expression of CyclinA2 or E-cadherin.Results:Compared with normal tissues adjacent to cancer, the expression level of miR-574-3p in 106 cases of colon cancer was significantly lower ( P<0.01). The decreased expression of miR-574-3p was related to tumor diameter, Dukes stage, histological grade and lymph node metastasis (all P<0.05), but not to age and tumor location (all P>0.05). The patients with low expression of miR-574-3p, high Dukes stage and histological grade, and lymph node metastasis had poor survival (all P<0.05). The 5-year overall survival rate of patients with decreased miR-574-3p expression in cancer tissue was significantly lower than that of patients without decreased miR-574-3p expression ( P=0.007 6). Compared with patients with no decreased miR-574-3p expression, patients with decreased miR-574-3p expression had higher CyclinA2 protein integrated optical density (IOD) value and lower E-cadherin protein IOD value in colon cancer tissues (all P<0.05). Conclusions:The decreased expression of miR-574-3p is related to the poor prognosis of colon cancer patients, which may affect tumor recurrence and metastasis by regulating the expression of CyclinA2 and E-cadherin proteins.

Objective The prevalence of obesity is constantly increasing. Multiple metabolic complications are related to obesity, including type 2 diabetes mellitus and non-alcholic fatty liver disease(NAFLD). Our study aimed to investigate the prevalence of obesity comorbidities and its association with BMI. Methods 765 individuals who visited the multidisciplinary clinic for obesity in Peking University First Hospital from 2015, Jun. to 2018, Sept. were enrolled in this study. The height, body weight, waist circumference, hip circumference were measured during the first visit. Body adipose percentage and basal metabolic rate were recorded. Questionnaires for daily food intake, comorbidity, and lifestyle were recorded. Fasting insulin, C peptide, glucose, HbA1C , uric acid, liver enzymes and lipid profile were measured. Statistical analysis was performed using SPSS 16. 0, and P<0. 05 was considered as statistical significant. Results Daily energy intake was higher in obesity group [ obese vs non-obese, (2136.6±739.4vs1905.7±468.4)kcal/d,P=0.046].Hypertension,NAFLDandgoutriskincreasedsignificantly in obesity group (obese vs non-obese, 36.0％vs 24.5％, P=0.02;76.5％ vs 60.6％, P<0.01;6.9％ vs 1.8％, P=0.04, respectively) . Family history of obesity and diabetes increased in obesity group ( obese vs non-obese, 64.5％vs 53.6％, P=0.03;47.4％vs 37.3％, P=0.048). Fasting insulin and C-peptide levels were higher in obesity group [obese vs non-obese, (24.8 ± 15.3 vs 13.6 ± 9.5)μIU/ml, P<0.01;(3.72 ± 1.40 vs 2.70 ± 1.16)μIU/ml, P<0.01). Liver enzymes increased significantly in obesity group [obese vs non-obese, (47.2±45.4 vs 23.3±21.4)U/L, P<0.01; ( 30. 4 ± 24. 0 vs 19. 9 ± 8. 5 ) U/L, P=0. 001 ] . Conclusions Obesity population had higher risk of hypertension, NAFLD and gout. Fasting insulin, C-peptide, liver enzymes, and UA also increased significantly in these patients. It is critically important to those obese individuals for regular screening of NAFLD and diabetes mellitus.

Objective To investigate the characteristics of clinical cellular immunity and its relationship with prognosis in elderly patients with severe infection caused by Omicron variant.Methods The clinical data of 53 patients with Omicron variant infection admitted to the geriatric Intensive Care Unit of the First Affiliated Hospital of Kunming Medical University from December 2022 to February 2023 were retrospectively analyzed.The patients were divided into 22 survival cases and 31 death cases for comparison between the two groups.Logistic analysis is adopted to define the omicron variants of elderly severe infections prognostic factors and construct the ROC curve.Results Mu-ltivariate logistic analysis revealed that the independent risk factors were elevated IL-6(P = 0.043)and decreased absolute T lymphocyte count(P = 0.011).AUC value of ROC of IL-6,absolute T lymphocyte count and IL-6 combined with absolute T lymphocyte count was 0.818,0.796 and 0.887.Conclusion Elevated IL-6 and decreased absolute T lymphocyte count are independent risk factors for elderly severe patients with Omicron variant infections.

Objective To explore the public's cognition and attitude towards general medicine,general practitioners,and pre-hospital first-aid knowledge in Ludian County,Yunnan Province,to find out the training and learning methods that are more acceptable to the public for this kind of related knowledge,and to propose targeted solutions.Methods A complete random sampling survey was conducted among the nucleic acid collection office at the gate of the vegetable market from October 15,2022,to December 30,2022,and the outpatient clinic of Wenping Street Health Center from January 1,2023,to February 28,2023,by using electronic questionnaire and paper questionnaire.Results Nearly 50%of the people in Ludian County of Yunnan Province lack the knowledge of general medicine and pre-hospital emergency care,especially the knowledge of electrical defibrillation.People with higher education and the medical profession have a higher understanding of general medicine,and people with a higher understanding of general medicine are more willing to participate in pre-hospital emergency care.The average Ridit value is:very familiar with general medicine(0.774)>Knowledge of some general practices(0.565)>Never heard of general practice(0.400).The higher education level and the more comprehensive understanding of general medicine had a positive impact on participation in pre-hospital emergency care,with B values of 0.624 and 0.619,OR 95%CI of 1.867(1.544～2.257)and 1.857(1.298～2.657),respectively.Taking medical staff as a reference,the B value of medical students was = 0.942,P = 0.234,the difference was not significant,and the B value of non-medical professional population was all less than 0,the effect is negative.In addition,most people have a positive attitude towards learning pre-hospital first aid,and more than 70%of people are willing to learn and train related knowledge of pre-hospital first aid.Conclusions People in urban areas of Ludian County,Yunnan Province have poor understanding of general practice,low recognition of general practitioners,low demand for general practitioners,and lack of awareness of the importance of pre-hospital emergency treatment.Because of the cognitive differences among different groups,it is necessary to conduct specific training for different groups.

Objective:To explore the application effect of situational case-based learning (CBL) teaching method in the surgical animal experiment course.Methods:The five-year clinical medicine students of the Batch 2016 teaching reform classes in Inner Mongolia Medical University were selected as the research objects. The teaching reform Class 1 was the control group, and the teaching reform Class 2 was the experimental group, with 36 students in each group. The control group adopted traditional teaching, while the experimental group introduced situational CBL teaching. The mid-term assessment of the course was carried out, using a multi-station examination including theory and skill operation. At the same time, a questionnaire survey of course satisfaction was carried out among the two groups of students. SPSS 22.0 was used for t-test and Chi-square test. Results:The theoretical performance of the experimental group (72.44 ±7.91) was significantly higher than that of the control group (60.49±8.23), and the performance of skill operation (77.69±7.13) was significantly higher than that of the control group (60.58±8.91). The course satisfaction of the experimental group was significantly higher than that of the control group.Conclusion:The introduction of situational CBL teaching could significantly improve the classroom teaching effect of surgical animal experiments, and be beneficial for medical students to master the basic skills of surgery and the related general theory knowledge of clinical medicine.
