Objective To investigate the efficacy,adverse effect and the incidence of cardiovascular and cerebrovascular events by comparative study on simvastatin combined with ezetimibe on therapy of lowing blood lipids in metabolic syndrome patients.Methods One hundred and twenty metabolic syndrome patients were divided into experiment group (n=60) and control group (n=60).The experiment group was treated with 20 mg of simvastatin associated 10 mg of ezetimibe daily.The control group was treated with conventional-dose 20 mg of simvastatin.The period of treatment was 4 years in both groups.The efficacy,adverse effect and the occurrence of cardiovascular and cerebrovascular events were observed and analyzed.Results Blood lipid were significantly decreased in both groups after the treatment.There was significant difference on total cholesterol ( TC ) [ ( 3.05±1.17 ) mmol/L vs (4.94 ± 1.13 ) mmol/L,P ＜ 0.05 ],low density lipoprotein cholesterol ( LDLC) [ (2.12±1.03) mmol/L vs (3.16 ± 1.11 ) mmol/L,P ＜0.05] and triglyceride(TC) (1.02±0.29) mmol/Lvs (1.65 ± 0.32)mmol/L,P ＜ 0.05 ) between experiment group and control group.There were 3 cases of cardiovascular events in experiment group and 10 cases in control group,5 cases of cerebrovascular events in experiment group and 13 cases in control group.The incidence of cardiovascular and cerebrovascular in experiment group was significantly lower than that in control group (x2 =4.08 and 4.37,respectively,P ＜ 0.05 ).Conclusion Combination therapy with simvastatin and ezetimibe is more effective and it can significantly decrease the incidence of cardiovascular and cerebrovascular events in metabolic syndrome patients.

Objective To construct two kinds of eukaryotic ccll expression vcctors pIRES2-EGFP-SP-B-C/T 1580 and evaluate their expressions in 293T cells,for the further study of relationship between polymorphism of surfactant protein B (SP-B) gene and bronchopulmonary dysplasia (BPD).Methods The eukaryotic pIRES2-EGFP-SP-B-C/T 1580 expression vectors were constructed by gene recombination,and identified by gene sequencing.The recombinant expression vectors were transfected into 293T cells by lipofectamine2000.The expression of green fluorescence protein in 293T cells was observed by fluorescence microscopy.The mRNAs and proteins of SP-B-C/T 1580 were tested and identified by reverse transcriptionpolymerase chain reaction-restriction fragment length polymorphism(RT-PCR-RFLP) and western blot.Results Two recombinant plasmids contained the complete cDNA of SP-B with the same sequence as in gene bank.The base of SP-B 1580 gene of pIRES2-EGFP-SP-B-C 1580 was C,that of pIRES2-EGFP-SP-B-T 1580 was T.After being transfected into 293T cells,highly efficient expression of SP-B-C/T 1580 gene was detected at mRNA and protein levels.Conclusions The pIRES2-EGFP-SP-B-C/T 1580 eukaryotic cell expression vectors were successfully constructed.

Objective:To explore the knowledge, attitude and practice (KAP) status of ICU nurses on enteral nutrition treatment of severe acute pancreatitis and to analyze its influencing factors.Methods:A total of 520 ICU nurses from 7 ClassⅢ Grade A hospitals in Henan Province from February to April 2022 were selected as research objects by the convenient sampling method. General Data Questionnaire and Clinical Nurses' Knowledge, Attitude and Practice Questionnaire on Enteral Nutrition Treatment of Acute Pancreatitis were used to investigate.Results:A total of 520 questionnaires were sent out, and 504 were effectively collected, with an effective recovery rate of 96.92%. The total score of ICU nurses' knowledge, attitude and practice in enteral nutrition for severe acute pancreatitis was (113.68±12.48), including knowledge dimension (10.67±2.58), attitude dimension (61.60±6.38), and practice dimension (41.42±7.44). There were positive correlation among ICU nurses' scores of knowledge, attitude and practice on enteral nutrition in patients with severe acute pancreatitis ( P<0.01). The results of multiple linear regression analysis showed that professional title, length of service in ICU nursing, personnel relations, whether to participate in specialized training, and whether to care for patients with severe acute pancreatitis and enteral nutrition were the influencing factors of knowledge dimension ( P<0.05). Post, whether to participate in specialized training, and whether to care for patients with severe acute pancreatitis undergoing enteral nutrition were influencing factors of attitude dimension ( P<0.05). Gender, professional title, post, whether to participate in specialized training, and whether to care for patients with severe acute pancreatitis undergoing enteral nutrition were the influencing factors of behavioral dimensions ( P<0.05) . Conclusions:ICU nurses have a positive attitude towards enteral nutrition treatment for severe acute pancreatitis, and their knowledge attitude and practice level need to be improved. Nursing managers should establish and improve a training system, strengthen the knowledge and behavior of ICU nurses on enteral nutrition for patients with severe acute pancreatitis and improve their management level of enteral nutrition for patients with severe acute pancreatitis, thereby improving the quality of nursing.

In order to train professionals in medical laboratory technology who are directly engaged in medical examination and medical laboratory work and who have strong practical ability and can adapt to the development of precision medicine, the reform of precise teaching for experiment is implemented. Through the precise stratification of experimental projects and knowledge points, the design of precise teaching activity and the construction of precise evaluation system for experiments, guided by precision medicine during the experimental process, the standardization and precision training of basic skills for students are strengthened in clinical laboratory test. The students can more well adapt to the needs of society for technical and innovative talent in the new period. The precise teaching for experiment will become one of the main characteristics of medical laboratory technology education in our school.

Objective:To explore the needs for discharge plans in patients with ischemic stroke and their family members, and provide a reference for formulating a scientific and standardized discharge plan.Methods:Totally 15 patients with hemiplegia after ischemic stroke admitted in our hospital between January and March 2019 and 15 family members received semi-structured in-depth interviews using phenomenological research methods in qualitative studies. Colaizzi analysis was used to encode, analyze, categorize and refine the data.Results:The needs for discharge plans in patients with hemiplegia after ischemic stroke were summarized into 5 themes, namely, disease knowledge, rehabilitation exercise, psychological support, financial support, and referral services; the needs for discharge plans in family members were summarized into 3 themes, namely, care knowledge/skills guidance, rehabilitation equipment guidance and respite care needs.Conclusions:Patients with hemiplegia after ischemic stroke and their family members have high needs for discharge plans. A personalized multidisciplinary collaborative discharge plan should be provided, and the role of communities in the follow-up rehabilitation treatment should be given full play to.
