ABSTRACT

Glucagon-like peptide-1 ( GLP-1 ) is secreted by gut enteroendocrine cells. GLP-1 receptor agonists ( GLP-1 RAs) control glucose-related augmentation of insulin and suppress glu-cagon secretion. GLP-lRAs also inhibit gastric emptying, food intake and limit weight gain. In the past decade, significant progresses have been made in the investigation on the effects of GLP-1 RAs on cardiovascular system. The potential advantages of oral small-molecule GLP-1 RAs could improve the application of this class of drugs. This review highlights the multiple cardiovascular profiles of GLP-1 RAs in the treatment of cardiovascular diseases to provide new insights into cardiovascular benefits of GLP-1 RAs.

ABSTRACT

Objective To investigate the prevalence of Anisakis infections in coastal marine fishes and awareness of anisakiasis control knowledge among local residents in Yantai City, Shandong Province in 2021, so as to provide insights into formulation of anisakiasis control interventions. Methods Marine fishes were purchased from Shunxin Port, Yantai City, Shandong Province in November 2021, and the presence of Anisakis was detected in different species of fishes and different fish sites. The correlations between body length and weight of marine fish and intensity of Anisakis infections were examined using Spearman’s rank correlation analysis, and the dietary habits and anisakiasis control knowledge were investigated using questionnaire surveys among local residents. Results A total of 201 marine fishes belonging to 20 species were dissected, and Anisakis was detected in 77 marine fishes (38.31%) belonging to 11 species (55.00%), with a mean infection intensity of 45.04 parasites per fish (3 468/77). Spearman’s rank correlation analysis revealed that the body length (rs = 0.74, P < 0.05) and weight (rs = 0.79, P < 0.01) of the monkfish correlated positively with the intensity of Anisakis infections, and the body length (rs = 0.68, P < 0.05) of the flatfish correlated positively with the intensity of Anisakis infections, while no correlations were examined between the body length or weight of other marine fishes and the intensity of Anisakis infections. Of all respondents, 53.38% men and 56.67% women did not know anisakiasis control knowledge at all, and there was a significant difference in the proportion of respondents using separate chopping boards for raw and cooked food from different villages (χ2 = 17.89, P < 0.01), while there was an age-specific proportion of respondents with habitats of eating raw or semi-raw seafood (χ2 = 28.27, P < 0.01). Conclusions The prevalence and intensity of Anisakis infections were high in coastal marine fishes in Yantai City in 2021, and the awareness of anisakiasis control knowledge was low among local residents. Intensified health education pertaining to anisakiasis control knowledge is recommended to reduce the risk of Anisakis infections.

ABSTRACT

The clinical tumor therapy was greatly challenged due to the complex characteristics of tumor microenvironment, however, which also provide arena for novel therapeutic strategies. In this study, poly(2-ethyl-2-oxazoline)-poly(lactic acid)-SS-poly(β-amino ester (PEOz-PLA-SS-PBAE) triblock copolymers with pH and GSH double response were synthesized, polymer micelles were prepared by thin film hydration method for loading of silybin to improve its antitumor activity. The critical micelle concentration was determined by pyrene fluorescence method as 1.8 μg·mL-1. The particle size was 155.30 ± 1.80 nm as determined by dynamic light scattering, with polydispersity index of 0.168 ± 0.004. The drug loading and entrapment efficiency of the micelles were determined by HPLC as (5.48 ± 0.04)% and (68.52 ± 0.48)%, respectively. The in vitro drug release profiles showed that the micelles have low pH sensitivity and high GSH responsiveness, and exhibited sustained release profiles. The good biocompatibility of the material was proved by measuring the hemolysis rate and cytotoxicity of the blank micelle. The cytotoxicity and apoptosis rate of tumor cells showed that the drug loaded PEOz-PLA-SS-PBAE micelles had significant inhibitory effect and apoptosis-inducing effect on MDA-MB-231 cells. The results of wounding healing assay and Transwell invasion test showed that the drug loaded PEOz-PLA-SS-PBAE micelles could significantly inhibit the metastasis of MDA-MB-231 cells. The PEOz-PLA-SS-PBAE drug-loaded micelles prepared in this study have good inhibitory effect on tumor growth and anti-tumor metastasis in vitro, which lays the foundation for the further application of silybin.

ABSTRACT

ObjectiveTo explore the effect and possible mechanism of electroacupuncture (EA) at Fenglong (ST40) on liver lipid synthesis and insulin resistance (IR) in hyperlipidemic (HLP) rats. MethodEighteen rats were randomly divided into three groups, blank group, model group, and EA group, each consisting of six rats. The blank group rats were with fed a basic diet, while those in the model group and EA group were fed high-fat diet for 8 weeks. After modeling, the rats in the EA group received bilateral EA treatment at “Fenglong” (ST 40). The rats in the model group underwent daily binding treatment, once a day, continuously 5 days a week, for a total of 4 weeks. Following the intervention, the levels of triglycerides (TG) and free fatty acids (FFA) in liver tissue was determined using ELISA. Serum TG, FFA, fasting insulin (FINS), alanine transaminase (ALT), aspartate Transaminase (AST), tumor necrosis factor-ɑ (TNF-ɑ)and interleukin 6 (IL-6) were also measured. The fasting plasma glucose (FBG) assessed using a glucose meter and the homeostatic model assessment of insulin resistance (HOMA-IR) was calculated. Liver pathology was examined through HE staining and oil red O staining. The expression of hepatic sterol regulator binding protein 1c (SREBP1c), recombinant fatty acid synthase (FASN) and stearoyl-CoA desaturase 1 (SCD1) were detected through immunofluorescence. The protein expression levels of liver insulin receptor substrate 1 (IRS1) and tyrosine-phosphorylated insulin receptor substrate 1 (p-IRS1-Tyr) were determined via Western blot. ResultsWhen compared to the blank group, the model group of rats exhibited elevated serum and liver tissue levels of TG and FFA, as well as increased serum levels of AST, ALT, TNF-α, IL-6, FBG, FINS, and HOMA-IR (P<0.05). HE staining revealed disordered arrangements of liver cells, indicating widespread fatty degeneration. Oil red O staining showed abundant bright red lipid droplets within liver cell cytoplasm, indicating severe lipid accumulation. The average fluorescence intensity of SREBP1c, FASN, and SCD1 in liver tissue significantly increased (P<0.05), while p-IRS1-Tyr protein expression levels significantly decreased (P<0.05). In comparison to the model group, the EA group of rats showed significantly reduced serum and liver tissue levels of TG and FFA, along with decreased serum levels of AST, ALT, TNF-α, IL-6, FBG, FINS, and HOMA-IR (P<0.05). HE staining indicated more regular arrangements of liver cells, and oil red O staining revealed a significant reduction in liver cell lipid droplets, indicating a less severe degree of lipid accumulation. The average fluorescence intensity of SREBP1c, FASN, and SCD1 in liver tissue significantly decreased (P<0.05), while p-IRS1-Tyr protein expression levels significantly increased (P<0.05), with no significant difference in IRS1 protein expression (P>0.05). ConclusionEA at “Fenglong” (ST 40) can significantly decrease serum lipid in HLP rats, improves liver fat accumulation, and also ameliorate insulin resistance. The mechanism may be related to the inhibition of hepatic lipid synthesis molecule expression, reduced serum inflammatory factors, and an increase in insulin substrate receptor phosphorylation levels.

ABSTRACT

ObjectiveTo observe the lower limb muscle activation strategy of healthy middle-aged and old women during stair ascent and descent with surface electromyography. MethodsFrom August, 2021 to February, 2022, 20 healthy middle-aged and old women were measured the surface electromyography root mean square (RMS) and integrated electromyography (iEMG) of bilateral vastus lateral, rectus femoris, vastus medialis, biceps femoris and semitendinosus during stair ascent and descent, and co-contraction ratio was calculated. ResultsDuring stair ascent, the RMS of bilateral vastus lateral, rectus femoris and vastus medialis was higher at starting stage than at following stage (|t| > 6.650, P < 0.001), while the RMS of biceps femoris and semitendinosus was lower (t > 3.559, P < 0.01); and the co-contraction ratio of hamstrings/quadriceps was lower at starting stage than at following stage (t > 8.185, P < 0.001). During stair descent, the RMS of bilateral vastus lateral, vastus medialis, biceps femoris and semitendinosus was higher at following stage than at starting stage (t > 2.345, P < 0.05), as well as the co-contraction ratio of hamstrings/quadriceps (t > 2.405, P < 0.05). ConclusionThe activities of the muscles around the knees are almost symmetrical during stair ascent and descent for healthy middle-aged and old women. The activation and co-contraction ratio of quadriceps and hamstring are various at starting/following stages.

ABSTRACT

Objective To investigate the clinical characteristics of drug-induced liver injury caused by anti-tuberculosis drugs in newly treated pulmonary tuberculosis patients with hepatitis B virus (HBV). Methods A total of 133 patients with pulmonary tuberculosis and HBV who were treated in Zhuzhou Central Hospital from January 2018 to early January 2022 were selected, and all were treated with conventional anti-tuberculosis 2HRZE/4HR regimen. According to the liver injury, the patients were divided into liver injury group and no liver injury group. Univariate analysis was used to analyze the related factors of liver injury caused by anti-tuberculosis drugs, and multivariate logistic regression analysis was used to analyze the independent risk factors of liver injury caused by anti-tuberculosis drugs. Results Among 133 cases of newly treated pulmonary tuberculosis patients with HBV, 24 cases had liver injury caused by anti-tuberculosis drugs, accounting for 18.05%; 109 patients had no liver injury caused by anti-tuberculosis drugs, accounting for 81.95%. Univariate analysis showed that there were significant differences in smoking history, drinking history, diabetes history, hypertension history, anti-tuberculosis treatment plan, malnutrition, and use of hepatoprotective drugs between the liver injury group and the no liver injury group (P<0.05). Multivariate logistic regression analysis showed that smoking history, drinking history, diabetes history, hypertension history, PZA-containing regimen, malnutrition, and no use of hepatoprotective drugs were independent risk factors for liver injury caused by anti-tuberculosis drugs. Conclusion Smoking history, drinking history, diabetes history, hypertension history, PZA-containing regimen, malnutrition, and no use of hepatoprotective drugs are the risk factors for drug-induced liver injury caused by anti-tuberculosis drugs in newly treated pulmonary tuberculosis patients with HBV.

ABSTRACT

Objective:To investigate the diagnostic value of thyroid imaging report and data system (TIRADS) combined with BRAF V600E mutation detection in differentiating uncertain thyroid nodules by using fine needle aspiration cytology (FNAC), and to analyze the role of TIRADS classification in screening the nodules needed to be routinely detected for BRAF V600E mutation.Methods:The clinicopathological data of 337 thyroid nodules patients diagnosed with TIRADS classification, FNAC Bethesda classification, BRAF V600E mutation detection and postoperative histopathology from the Second Hospital of Hebei Medical University between January 2018 and August 2021 were retrospectively analyzed. The role of TIRADS classification, FNAC Bethesda classification and BRAF V600E mutation detection alone and the combined detection in the differentiation of benign and malignant thyroid nodules was also analyzed.Results:The postoperative histopathological result was regarded as the gold standard. The sensitivity of TIRADS classification, FNAC Bethesda classification and BRAF V600E mutation for thyroid cancer diagnosis was 76.0%, 88.1% and 80.4% respectively, and the corresponding specificity was 84.0%, 96.0% and 100.0%, respectively. Histologically, 37 (62.7%) of 59 nodules with FNAC uncertainty were malignant nodules after the surgery. The sensitivity and accuracy of BRAF V600E mutation detection in the diagnosis of FNAC uncertain nodules were 51.4% and 69.5%, respectively, while the sensitivity and accuracy of BRAF V600E mutation detection combined with TIRADS classification were 86.5% and 84.7%, respectively. The sensitivity and accuracy of BRAF V600E mutation detection combined with TIRADS classification were both improved ( P values were 0.002 and 0.049, respectively). The positive rate of BRAF V600E mutation in thyroid nodules increased step by step with the rise of risk degree in TIRADS classification, and the type 3 cases were lower than those in type 4a cases [14.3% (1/7) vs. 68.6% (24/35), P = 0.012], and there were no statistically significant differences among the adjacent groups above 4a (all P > 0.05). Conclusions:TIRADS combined with BRAF V600E mutation detection can improve the sensitivity and accuracy in the diagnosis of FNAC uncertain thyroid nodules. The BRAF V600E mutation rate of TIRADS 4a and above nodules is high, so routine detection is recommended.

ABSTRACT

Objective:To explore the establishment of a surgical complication monitoring mode based on data on the medical record homepage, and analyze its impact on the trend of changes in surgical complication incidence.Methods:A monitoring mode of surgical complication was developed based on the " structure-process-results" framework by using surgical complication rates derived from performance appraisal for a tertiary general hospital in Guangzhou. The number of surgical complications and the number of discharged surgical patients was collected from the hospital from January 2019 to June 2022 through the home page collection system for performance appraisal of national tertiary public hospitals. Descriptive analysis was used to analyze the incidence of surgical complications, and Joinpoint regression was used to analyze the trend of changes in the incidence of surgical complications. Monthly percentage change ( MPC) and average monthly percentage change ( AMPC) were calculated. Results:Since the hospital began implementing the surgical complication monitoring mode in May 2021, the incidence of surgical complications had decreased from 2.55% in June 2021 to 0.82% in June 2022, with an MPC of -5.58% ( P=0.024), which was better than the changes from January 2019 to May 2021 ( MPC=0.18%, P=0.755). Conclusions:The surgical complication monitoring mode constructed by the hospital can effectively reduce the incidence of surgical complications, providing reference for optimizing hospital′s medical quality management process and decision-making mode.

ABSTRACT

Objective:To provide data reference for using Chinese rhesus macaques as research model by studying the immunophenotype and function of peripheral blood lymphocytes in Chinese rhesus macaques.Methods:By optimizing antibody clones and fluorescent colors, the lymphocyte subset assay and T cell function assay panels were determined. Then the panels were used to analyze the proportion of T, B, NK and other cell subsets in peripheral blood mononuclear cells (PBMCs) in 15 healthy Chinese rhesus monkeys, and the ability of T cells to secrete cytokines after non-specific stimulation.Results:Two multi-color flow cytometry analytic panels were established. Panel 1 could simultaneously detect a variety of lymphocyte subsets, including cytotoxic T lymphocytes, follicular helper T cells, regulatory T cells, B cells and NK cells. Panel 2 could detect the functions of multiple T cell subsets and the expression of immune checkpoint moleculars. The mean percentages of T, B, NK, Tfh, Treg, CD16 + NK and CD56 + NK cells in PBMCs of the Chinese rhesus macaques were (75.32±7.73)%, (13.22±7.50)%, (0.88±0.48)%, (0.73±0.27)%, (0.75±0.43)%, (47.87±22.35)% and (10.69±12.41)%. After non-specific stimulation, the proportion of CD4 + T cells secreting IL-2 and TNF-α was higher than that of CD8 + T cells, and the proportion of CD8 + T cells secreting CD107a and IFN-γ was higher than that of CD4 + T cells, while the proportion of CD4 + and CD8 + T cells secreting IL-17A was low. Conclusions:This study established a multi-color flow detection scheme that could simultaneously detect multiple cellular surface molecules and cytokines at the single cell level and could accurately and comprehensively analyze the immune cell subsets, functions and the immune checkpoint molecules in peripheral blood of Chinese rhesus macaques, providing a new experimental method and basic data for the development of vaccines and drugs against infectious diseases.

ABSTRACT

Objective:To investigate the reference ranges for thyroid function and its influencing factors in preterm infants at 14 d after birth.Methods:This retrospective study involved 514 preterm infants who met the inclusion criteria in Affiliated Hospital of Inner Mongolia Medical University from January 1, 2019 to December 31, 2021. They were divided into three group according to their gestational age [early premature group (26-31 +6 weeks, n=153), middle premature group (32-33 +6 weeks, n=129) and late premature group (34-36 +6 weeks, n=232)] or birth weight (BW) [<1 500 g group ( n=129), 1 500-2 000 g group ( n=120) and ≥2 000 g group ( n=265)]. Venous blood samples were collected from the infants at 14 d after birth and their thyroid function was determined by chemiluminescence immunoassay. The reference values of free triiodothyronine (FT 3), free thyroxine (FT 4) and thyroid stimulating hormone (TSH) were calculated based on the values of 95% confidence intervals ( CI) and expressed as percentiles in the range from P2.5 to P97.5. Mann-Whitney U test or Kruskal-Wallis H test was used to compare those thyroid hormone levels between groups. Spearman correlation analysis was used to study the correlation of gestational age or birth weight with FT 3, FT 4 and TSH levels. The factors influencing the levels of thyroid hormones were analyzed by multiple linear regression. Results:The reference ranges for FT 3, FT 4 and TSH were 1.53-3.72 pg/ml, 0.81-1.91 ng/dl and 1.32-7.80 μIU/ml in the early premature infants, 1.74-4.16 pg/ml, 0.90-2.82 ng/dl and 0.63-7.64 μIU/ml in middle prematures and 2.07-4.88 pg/ml, 1.09-2.27 ng/dl and 1.14-7.06 μIU/ml in late prematures. The reference ranges for the above three indexes were 1.53-4.06 pg/ml, 0.81-1.83 ng/dl and 1.14-7.84 μIU/ml in premature infants with BW<1 500 g, 1.67-3.98 pg/ml, 0.88-2.97 ng/dl and 0.94-7.64 μIU/ml in those whose BW between 1 500 g and 2 000 g and 1.91-4.75 pg/ml, 1.09-2.31 ng/dl and 1.14-6.32 μIU/ml in those whose BW≥2 000 g. Multiple linear regression showed that the level of FT 3 was positively correlated with gestational age ( β=0.119, P<0.05) and birth weight ( β=1.950×10 -4, P<0.05); that of FT 4 was positively correlated with gestational age only ( β=0.031, P<0.05); and TSH level was negatively correlated with birth weight ( β=-4.250×10 -4, P<0.05). Conclusions:Gestational age and birth weight are the factors influencing thyroid function in preterm infants at 14 d after birth. Evaluation of thyroid function with FT 4 and TSH should based on the references ranges of different gestational age and birth weight .

ABSTRACT

Objective:To explore the relationship between the triglyceride glucose (TyG) index and impairment of renal function in community-dwelling middle-aged and elderly population.Methods:A total of 4 988 residents aged ≥45 years undergoing health check-up in Yongshun Health Service Center from January 2016 to December 2021 were enrolled and followed up. According to the quartile of the baseline TyG index, all subjects were divided into Q1, Q2, Q3 and Q4 groups. The medical history, physical examination and laboratory test results were documented. Participants were followed up through regular health check-up until March 31, 2023. The outcomes were rapid decline of estimated glomerular filtration rate (eGFR) (a loss in eGFR>3 ml·min -1·1.73 m -2 per year) and the new-onset of chronic kidney disease (CKD) during the follow-up period. Linear regression model, multivariate logistic regression model, restricted cubic spline fitting logistic regression model and ROC curve analysis were used to analyze the association between the TyG index and the impairment of renal function. Results:Among 4 988 residents, 1 396 (28.0%) were males and the age was (59.76±6.28) years. There were 1 247 participants in Q1, Q2, Q3 and Q4 groups, respectively. After 56 months of follow-up, the incidence of rapid eGFR decline and new-onset CKD was 21.9% (1 294/4 988) and 4.0% (200/4 988), respectively. Multivariate logistic regression model analysis showed that TyG index was correlated positively with rapid eGFR decline and new-onset of CKD ( OR=1.34, 95%CI: 1.17-1.52, P<0.001, and OR=1.57, 95%CI:1.19-2.06, P=0.001). Taking group Q1 as a reference, higher levels of TyG index ( Q2, Q3 and Q4 groups) was an independent risk factor for rapid eGFR decline ( P<0.05), which has a dose-response relationship (for trend P=0.002). Compared with the lowest quartile, the adjusted OR of new-onset CKD in the highest quartile was 1.85 ( 95%CI:1.13-3.03, P=0.014). The results of restricted cubic spline fitting logistic regression analysis showed a linear association between TyG index and both outcomes (both P>0.05). The area under ROC curve ( AUC) of the TyG index for predicting the two adverse outcomes were 0.536 ( 95%CI: 0.516-0.556, P<0.001) and 0.588 ( 95%CI:0.548-0.627, P<0.001), respectively. Conclusion:The elevated levels of TyG index may be used as an independent predictor of rapid eGFR decline and new-onset CKD.

ABSTRACT

Objective:To investigate the association between plasma uric acid and hypertension and the gender difference in community-dwelling middle-aged and elderly population.Methods:A community-based cross-sectional study was conducted in Beijing Tongzhou Yongshun Community Health Service Center from June to December 2021, among residents aged 45 years or older selected by cluster sampling method. According to plasma uric acid (UA) level in quartiles, the subjects were divided into 4 groups; and stratified by gender, the subjects were further divided into subgroups. Multivariate logistic regression model was used to analyze the related factors of hypertension, and restricted cubic spline fitting logistic regression model was used to analyze the nonlinear association between uric acid and hypertension and the cut-off values of uric acid.Results:A total of 6 229 residents with the age of (63.2±7.3) years were enrolled in the study. In 1 874 male participants (30.1%), 946 participants (50.5%) had hypertension, and the uric acid level was 359 (309, 418)μmol/L; in 4 355 female participants (69.9%), 2 003 participants (46.0%) had hypertension, and the uric acid level was 306 (261, 359)μmol/L. Multivariate logistic regression analysis showed that after adjusting for factors that were statistically significant in univariate analyses or potentially clinically relevant (including age, body mass index, diabetes mellitus, coronary heart disease, cerebrovascular disease, albumin, estimated glomerular filtration rate, and cholesterol), uric acid was independently associated with hypertension ( P<0.001), for total participants the risk of hypertension in Q4 group was 1.33 times of that in Q1 group ( OR=1.33,95% CI 1.13-1.56, P=0.001); while for females the risk of hypertension in Q4 group was 1.38 times of that in Q1 group ( OR=1.38,95% CI 1.13-1.68, P=0.002), but no significant association was observed for males ( P>0.05). The results of restricted cubic spline fitting logistic regression analysis showed that there was a linear association between uric acid level and hypertension in the total population and males, and the risk of hypertension increased with uric acid level ( P<0.001 for the total population, P=0.016 for male). However, there was a non-linear association in females. When uric acid>307 μmol/L in females, the risk of hypertension increased significantly as the level of uric acid increased ( P<0.001). Conclusions:Uric acid level was independently associated with hypertension in the community-dwelling middle-aged and elderly population, and there was a gender difference in the correlation. The association was nonlinear in females and the cut-off value of uric acid in females was 307 μmol/L.

ABSTRACT

Objective:To compare the effects of low-carbohydrate diet (LCD) and low-fat diet (LFD) in the lifestyle intervention of non-alcoholic fatty liver disease (NAFLD) through a meta-analysis of randomized controlled trials.Methods:PubMed, Embase, Web of Science, Cochrane, CNKI and Wanfang were searched for relevant studies and study references and conference proceedings were manually searched. Two authors independently screened the items retrieved, extracted the data and assessed the quality of included studies. Meta-analysis was performed using R4.4.1 and RevMan5.4.1. Data were pooled using random-effects models and potential sources of heterogeneity were investigated using stratified meta-analysis. Funnel plots and Peters' test were used to assess publication bias.Results:Nine studies with a total of 510 participants met our inclusion criteria. Meta-analysis results showed that LCD and LFD interventions had similar effects on the reduction of intrahepatic lipid content in NAFLD patients ( SMD: -0.31,95% CI: 0.97 to 0.35, P = 0.36). There were no significant differences in changes of alanine aminotransferase ( SMD: -0.25, 95%CI: 0.91 to 0.41, P = 0.45) and aspartate aminotransferase ( SMD: -0.45, 95%CI: 1.63 to 0.72, P = 0.45) levels, either. Subgroup analyses implied that the duration of different interventions might be the cause of heterogeneity across studies. No significant publication bias was showed in the meta-analysis. Conclusion:Current evidence from randomized controlled studies does not support the superiority of LCD over LFD in the treatment of NAFLD.

ABSTRACT

Objective:To explore the application effects of multiple teaching methods based on the outcome-based education (OBE) on the teaching of physiology.Methods:The application of multiple teaching methods based on the OBE was used in physiology teaching for 356 students majoring in anesthesiology, stomatology, medical imaging, and psychiatry of five-year undergraduate from 2020 in Shenyang Medical College. Analysis and assessments were done by course examinations and questionnaires. SPSS 16.0 was used for t-test. Results:According to the course examinations, students got higher scores in the medical licensing examination than in the western medicine integrated examination [(88.19±16.35) points vs. (66.69±21.45) points, P < 0.001], and students had higher scores in the final exam (A2 questions) than in the final exam (A1 questions) [(70.63±17.67) points vs. (63.16±14.80) points, P < 0.001]. At the same time, the results of questionnaires showed that students had a positive attitude towards multiple teaching methods. Conclusion:The multiple teaching methods based on the OBE applied in the teaching of physiology can enhance the comprehensive learning ability and future position competence of students, and improve the teaching quality.

ABSTRACT

Objective:To understand the current situation of knowledge, attitude and practice about target temperature management (TTM) in patients with severe traumatic brain injury (STBI) among intensive care unit ICU nurses and analyze the influencing factors, so as to provide a reference for conducting ICU nurses′ TTM training for patients with STBI.Methods:Applying the method of cross-sectional study, from November to December 2022, a stratified whole-group sampling method was used, stratified by first-, second-, and third-level hospitals, and a self-designed questionnaire on the current status of ICU nurses′TTM for patients with STBI was used to investigate the current status of knowledge, attitude, and practice of neurosurgical ICU, emergency ICU, and comprehensive ICU nurses in 22 second- and third-level hospitals in 11 cities in Gansu Province, and multiple linear regression analysis was used to analyze the factors influencing ICU nurses′ knowledge, attitude, and practice scores.Results:A total of 543 valid questionnaires were returned, and the scores of ICU nurses on the TTM total score, knowledge, attitude and practice dimensions of STBI patients were (76.75 ± 10.42), (7.38 ± 2.74), (39.57 ± 4.87), (29.80 ± 7.18) points respectively. The results of multiple linear regression analysis showed that the factor influencing ICU nurses′ scores on the TTM knowledge dimension for STBI patients was having attended TTM-related training ( t = 2.16, P<0.05); the factors influencing ICU nurses′ scores on the TTM attitude dimension for STBI patients were college, bachelor′s degree and the position of nurse practitioner ( t = 2.65, 2.91, 2.14, all P<0.05); and the factors influencing ICU nurses′ scores on the TTM practice dimension for STBI patients were the age group of 36 to 45 years old, the department having TTM-related criteria and having knowledge of TTM-related guidelines ( t = -2.46, 2.64, 3.85, all P<0.05). Conclusions:ICU nurses have a more positive attitude toward TTM in patients with STBI, but the level of knowledge and practice needs to be improved. Managers should conduct relevant training according to the current situation and influencing factors to improve ICU nurses′ knowledge and practice of TTM in patients with STBI, ensuring the effectiveness and safety of TTM.

ABSTRACT

Objective:To understand the current status, development trend of nursing fecal bacteria transplantationand comparison with the research in China, and provide guidance and reference for the follow-up research.Methods:The bibliometrics method was used to analyze the contents of fecal bacteria transplantation literatures in Wanfang Data, China National Knowledge Infrastructure, VIP Database from 2012 to 2021.Results:According to the inclusion and exclusion criteria, a total of 881 articles were included, including 54 nursing articles and 827 clinical medicine articles related to faecal bacteria transplantation. Since 2013, the number of publications published in nursing showed a slow increase and then a gradual decline. Jiangsu Province had the largest number of publications (15 articles, 27.8%). Of the 38 papers supported by the foundation, 9 were funded by China Natural Science.Conclusions:Faecal bacteria transplantation in China has developed rapidly in the past ten years, and a series of studies have been formed. However, the depth and breadth of the research on faecal bacteria transplantation in nursing care are insufficient. More researchers should be involved in the later stage, to strengthen cooperation and exchanges between medical staff, formulate related contents of faecal bacteria transplantation with nursing characteristics, and increase the breadth and depth of the content of faecal bacteria transplantation in nursing care.

ABSTRACT

Objective:To systematically integrate the attitudes and experiences of medical staffs towards the family presence during resuscitation and provide a reference for the development of family presence during resuscitation clinical practice in China.Methods:To search PubMed, Embase, Web of Science, The Cochrane Library, CINAHL, CNKI, CBM and Wanfang database for qualitative studies on medical staff's attitudes and experiences of family presence during resuscitation since its inception to August 2022. The quality of the literature was evaluated using the Australian JBI Centre for Evidence-Based Health Care (2017) quality assessment criteria for qualitative studies, which were integrated using a pooled integration approach.Results:A total of 12 papers were included to distil the findings of 74 studies, which were summarized to form 10 new categories and 4 consolidated findings including medical staffs′ attitudes towards and reasons for family presence during resuscitation, the impact of family presence during resuscitation on the resuscitation team, the impact of family presence during resuscitation on patients and families, and the real-life dilemmas and recommendations for medical staffs to allow family presence during resuscitation.Conclusions:We should pay attention to the difficulties and needs of family presence during resuscitation by medical staff, take into account the medical context in China, and improve the humanistic care system in our hospitals by considering hospital management, clinical practice, and the demands of patients and their families, in order to improve the accessibility of family presence during resuscitation by the medical staff.

ABSTRACT

Objective:To observe the effects of electroacupuncture preconditioning on the autophagy-related pathway protein kinase B (Akt)/mammalian target of rapamycin (mTOR) in myocardial tissue of rats with myocardial ischemia reperfusion injury (MIRI); To investigate the protective mechanism of "Neiguan"(PC 6) on myocardial injury.Methods:Totally 48 SD rats were randomly divided into blank group, sham-operation group, model group and Neiguan group ( n=12 in each group). The Neiguan group was applied to bilateral "Neiguan"(PC 6) by electroacupuncture for 30 min, once daily for consecutive 7 days before model replication. Except in the blank group, the MIRI model was established by ligation of the descending anterior branch of the left coronary artery in the rest groups after the intervention. The histomorphological changes in the myocardium of the rats were observed by HE staining, and the expression levels of Akt, phosphorylated Akt (p-Akt), mTOR and phosphorylated mTOR (p-mTOR) in the myocardium were measured by protein immunoblotting. The ratio of p-Akt/Akt and p-mTOR/mTOR was calculated. Results:In the blank group, the myocardial fibres were arranged regularly and neatly, and no inflammatory cell infiltration or haemorrhage was seen in the interstitium; in the sham-operation group, the arrangement of myocardial fibers was slightly irregular, no rupture was found, and a small amount of myocardial fiber gap was slightly enlarged; in the model group, the distribution of myocardial fibers was disordered, hypertrophic cardiomyocytes increased, some mitochondria were red and swollen or the outer membrane was ruptured, and inflammatory infiltration and hemorrhage were seen in the interstitium; the extent of myocardial lesions in the Neiguan group was less than that in the model group, with a small amount of interstitial hemorrhage and inflammatory cell infiltration. There was no statistical significance in the levels of Akt and mTOR in the myocardial tissues of the rats in each group ( P>0.05); compared with the sham-operation group, the levels of p-Akt, p-mTOR and p-Akt/Akt, p-mTOR/mTOR in the model group decreased ( P<0.01); compared with the model group, the levels of p-Akt, p-mTOR and p-Akt/Akt, p-mTOR/mTOR in the Neiguan group increased ( P<0.01). Conclusion:Electroacupuncture preconditioning may inhibit excessive autophagy by activating the Akt/mTOR pathway in cardiomyocytes of MIRI rats, thereby exerting a protective effect on the myocardium.

ABSTRACT

The disorder of autophagy lysosomal pathway (ALP) is an important pathogenesis of neuronal damage after cerebral ischemia, and the restoration of ALP may alleviate neuronal damage after cerebral ischemia. As the main transcription factor regulating ALP, transcription factor EB (TFEB) can directly regulate autophagosome generation, autophagosome-lysosome fusion, and autophagic flux by regulating the expression of autophagic genes and lysosomal genes. Therefore, regulating TFEB can alleviate ALP dysfunction and thereby reduce cerebral ischemic damage. This article reviews the structure, biological function of TFEB and its role in regulating ALP to alleviate neuronal damage after cerebral ischemia.
