Objective To investigate the cognition level and behavior compliance of blood pressure measurement in community residents and analyze the related influencing factors, and to provide evidence for community health management and blood pressure control. Methods A questionnaire survey was conducted to investigate 4470 community patients. Questionnaires included basic personal information，blood pressure measurement cognition, and blood pressure measurement behavior related issues. SPSS 19.0 was used to analyze the basic information, blood pressure measurement cognition, and pressure measurement behavior of the survey subjects. Logistic regression was performed to analyze relevant factors affecting blood pressure measurement cognition and behavior compliance. Results The overall cognitive compliance rate for blood pressure measurement among the visiting community patients was 31.52%. Age, education level, and chronic disease had a statistically significant impact on the cognitive knowledge (P<0.05). The overall behavior compliance rate of blood pressure measurement among the community patients was 23.69%. The cognition, age and education had a statistically significant impact on the overall behavior compliance rate of blood pressure measurement (P<0.05). Conclusion The cognitive level and standardized behavior of blood pressure measurement of community patients need to be improved. More attention should be paid to the elderly, low education level residents and community residents without chronic diseases, to promote community residents to form correct and standardized behavior of blood pressure measurement through health education.

BACKGROUND:Cognitive impairment is the most common complication after stroke,and its severity is closely related to the patient's prognosis.The prognosis of patients can be significantly improved if the severity of their cognitive impairment is recognized and targeted early.OBJECTIVE:To initially explore potential biomarkers affecting the progression of post-stroke cognitive impairment,thereby providing a richer and unique reference for the study of their pathophysiological mechanisms.METHODS:Using ultra performance liquid chromatography-mass spectrometry,non-targeted metabolomics analysis was conducted on serum samples from patients with mild and moderate post-stroke cognitive impairment to identify differential metabolites between the two groups.To further validate the diagnostic efficacy of the differential metabolites,the receiver operating characteristic curve analysis was used to evaluate their accuracy and sensitivity in distinguishing disease severity.In addition,pathway analysis was conducted on the differential metabolites.RESULTS AND CONCLUSION:(1)There were significant differences in metabolic profiles between patients with mild and moderate post-stroke cognitive impairment,and 9 differential metabolites were screened by the receiver operating characteristic curve.(2)Differential metabolite pathway analysis revealed that the metabolic pathways affecting disease progression in patients with mild-to-moderate post-stroke cognitive impairment included tryptophan metabolism,D-amino acid metabolism,biotin metabolism,retinol metabolism,aminoacyl-tRNA biosynthesis,lysine degradation,protein digestion and uptake,pyrimidine metabolism,cysteine and methionine metabolism,ABC transporter proteins,amino acid biosynthesis,and 2-oxocarboxylic acid metabolism.To conclude,9 potential biomarkers affecting disease progression in patients with mild-to-moderate post-stroke cognitive impairment have been identified,involving 12 metabolic pathways including tryptophan metabolism,D-amino acid metabolism and retinol metabolism.

Objective:Comparative analysis of the mNUTRIC and NRS-2002 scores for evaluating nutritional risk and predicting clinical outcomes in end stage liver disease patients.Method:A retrospective cohort study method was used to screen 114 cases with end-stage liver disease admitted to the intensive care unit (ICU) of the First Hospital of Lanzhou University from December 1, 2016 to March 31, 2021 according to the inclusion and exclusion criteria. The patient's demographic data, blood routine, blood biochemical indexes, coagulation function indexes, arterial blood gas analysis and imaging examination data were collected. The mNUTRIC score, NRS-2002 score, sequential organ failure (SOFA) score, model for end-stage liver disease (MELD) score, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, Child-Pugh grade, and clinical outcomes at 28 and 90 days at 24 h post-ICU admission were collected. The differences in clinical indicators between the mNUTRIC high group (≥5 points) and the low group, and the NRS-2002 high group (≥3 points) and the low group were compared. Spearman correlation analysis was used to explore the correlation between the mNUTRIC score and NRS-2002 score, clinical indicators, and 28 and 90-day mortality rates. Multivariate logistic regression analysis was used to determine the risk factors associated with 28-day and 90-day mortality in patients. The value of mNUTRIC score and NRS-2002 score in assessing the clinical outcomes of patients with end-stage liver disease was explored by receiver operating characteristic (ROC) curve.Results:The clinical indicators related to nutritional status of patients were worse in the high-mNUTRIC group than those in the low-mNUTRIC group, and the 28-day and 90-day mortality rates were significantly higher than those in the low-mNUTRIC group [89.0%(65/73) vs. 29.2%(12/41), 97.2%(71/73) vs. 39.0%(16/41), P<0.001]. There was no statistically significant difference in the incidence rate of hepatic encephalopathy, esophageal variceal bleeding, and ascites between the high and low mNUTRIC group. The clinical indicators related to nutritional status were worse in the high-NRS-2002 group than those in the low-NRS-2002 group of patients, and the 28-day and 90-day mortality rates were significantly higher than those in the low-group [73.0%(73/100) vs. 4/14, 81.0%(81/100) vs. 6/14, P=0.008, 0.004]. The NRS-2002 high-score group did not differ significantly from the low-score group in terms of hepatic encephalopathy, esophagogastric variceal bleeding, or ascites prevalence. Patient's age, white blood cell count (WBC), urea nitrogen (BUN), creatinine (UREA), uric acid (UA), total cholesterol (TG), Child-Pugh, MELD, SOFA, APACHE Ⅱscores were significantly positively correlated with the mNUTRIC score. Conversely, albumin (Alb) and Glasgow Coma Scale (GCS) were significantly negatively correlated. Patient's age, WBC, CREA, BUN, UREA, UA, Child-Pugh, MELD, SOFA, APACHE Ⅱwere significantly positively correlated with the NRS-2002 score.Conversely, albumin (Alb) and Glasgow Coma Scale (GCS) were significantly negatively correlated ( P<0.05). The 28-day and 90-day mortality rates of patients increased with the increase in the mNUTRIC scores. The mNUTRIC score was an independent predictor of death within 28 and 90 days in patients with end-stage liver disease. The area under the curve (AUC) of mNUTRIC for predicting patient death at 28 days was 0.864 (95% CI: 0.794-0.934). The AUC of NRS-2002 for predicting patient death at 28 days was 0.683 (95% CI: 0.573-0.792). The AUC of the two indicators combined for predicting patient death at 28 days was 0.868 (95% CI: 0.799-0.936). The AUC of mNUTRIC for predicting patient death at 90 days was 0.915 (95% CI: 0.861-0.969). The AUC of NRS-2002 for predicting patient death at 90 days was 0.715 (95% CI: 0.599-0.832). The AUC of the two indicators combined for predicting patient death at 90 days was 0.922 (95% CI: 0.871-0.972). Conclusion:mNUTRIC score and NRS-2002 score can better evaluate the nutritional status in patients with end-stage liver disease. The mNUTRIC score is a good predictor of 28-day and 90-day mortality in patients with end-stage liver disease, and its application value efficacy is enhanced when combined with NRS-2002.

Objective:To explore the risk factors for malnutrition after a tracheotomy and to construct a predictive model useful for its prevention through early intervention.Methods:Clinical data describing 440 tracheotomy patients were subjected to a retrospective analysis. The variables examined were age, sex, etiology, Glasgow Coma Score (GCS), activities of daily living (ADL) score, age-corrected Charlson comorbidity index (aCCI), food intake, swallowing function, incidence of infections, as well as any history of diabetes mellitus, hypertension, smoking or alcohol consumption. Patients identified as being at risk of malnutrition (NRS-2002≥3) were screened using the Nutritional Risk Screening tool (NRS-2002) and the European Society of Clinical Nutrition and Metabolism′s ESPEN2015 criteria. The subjects were thus categorized into a malnutrition group of 343 and a control group of 97. Unifactorial and multifactorial logistic regression analyses were performed, and stepwise regression was applied to include the factors found significant in the unifactorial analysis into the multifactorial logistic regression analysis, and to construct a column-line graph prediction model. The clinical utility of the model was assessed by applying the receiver operator characteristics (ROC) curves, calibration plots and decision curve analysis (DCA).Results:Of the 440 persons studied, 343 (78%) were malnourished. The multivariate logistic regression analysis showed that pulmonary infection, dysphagia, low GCS score and high aCCI score were significant risk factors for malnutrition after a tracheotomy. A prediction nomograph was constructed. After fitting and correcting, the area under the curve (AUC) of the prediction model′s ROC curve was 0.911, the specificity was 80.4%, and the sensitivity was 91.3%. That was significantly higher than the AUCs for pulmonary infection (0.809), dysphagia (0.697), aCCI (0.721) and GCS (0.802). Bootstrap self-sampling was used to verify the model internally. After 1000 samples the average absolute error between the predicted risk and the actual risk was 0.013, indicating good prediction ability. The DCA results demonstrated that the model has substantial clinical applicability across a range of nutritional interventions, particularly for threshold probability values ranging from 0 to 0.96.Conclusion:Pulmonary infection, dysphagia, low GCS score, and high aCCI score are risk factors for malnutrition among tracheotomy patients. The nomogram model constructed in this study has good predictive value for the occurrence of malnutrition among such patients.

Objective:To evaluate the effects of low-dose esketamine on postoperative pain and depression degree in patients undergoing radical surgery for colorectal cancer.Methods:A prospective randomized controlled study was conducted. Eighty-four patients who plan to undergo elective radical resection for colorectal cancer at Shanxi Province Cancer Hospital from December 2023 to March 2024 were divided into esketamine group (observation group) and 0.9% NaCl solution group (control group) using the random number table method, with 42 patients in each group. The observation group was given intravenous infusion of 0.25 mg/kg esketamine 30 minutes before anesthesia induction and 30 minutes before the end of surgery, while the control group was given intravenous infusion of the equal dose of 0.9% NaCl solution. The remaining anesthesia methods were the same for both groups. The postoperative pain number rating scale (NRS) scores, Ramsay sedation score and perioperative dosages of sufentanil, remifentanil and propofol were compared between the two groups. The Hamilton depression rating scale (HAMD) score was used to evaluate the degree of depression before and after surgery in two groups of patients and the score was compared between the two groups.Results:Two cases were discharged from the observation group and two cases were discharged from the control group due to postoperative catheterization and return to the intensive care unit. There were no statistically significant differences in gender, age, body mass index, anesthesia time, recovery time, extubation time, intraoperative fluid replacement volume, and fluid output between the two groups of patients (all P > 0.05). The dosage of remifentanil in the observation group was lower than that in the control group [(481±117) mg vs. (718±161) mg], and the difference was statistically significant ( t = 7.52, P < 0.001). The NRS scores of the observation group were lower than those of the control group at 1 and 2 hours after surgery, and the differences were statistically significant (both P < 0.001). The perioperative salvage analgesia rate in the observation group was lower than that in the control group [12.5% (5/40) vs. 32.5% (13/40)], and the difference was statistically significant ( χ2 = 4.59, P = 0.032). The Ramsay sedation scores of the observation group were higher than those of the control group at 1, 2, and 4 hours after surgery, and the differences were statistically significant (all P < 0.001). The HAMD scores of the observation group at 3 and 7 days after surgery were lower than those before surgery, and both were lower than those of the control group, and the differences were statistically significant (all P < 0.05). Conclusions:Low-dose esketamine used in radical surgery for colorectal cancer can not only effectively reduce perioperative pain and improve sedative effects, but also alleviate patients' depression and improve the quality and speed of postoperative recovery.
