Objective:To investigate the predictive value of circulating miR-143 and miR-182 for the short-term clinical outcomes in patients with acute ischemic stroke (AIS).Methods:Patients with AIS admitted to Danzhou People's Hospital from January 2018 to June 2020 were included prospectively. The modified Rankin Scale was used to evaluate the short-term clinical outcome at 14 d after onset or at discharge. 0-2 was defined as good outcome, and >2 was defined as poor outcome. Multivariate logistic regression analysis was used to identify the independent risk factors for poor short-term clinical outcomes in patients with AIS. The receiver operating characteristic (ROC) curve was used to evaluate the predictive value of miR-143 and miR-182 for the short-term clinical outcomes in patients with AIS. Results:A total of 158 patients with AIS, aged 65.80±12.36 years, were enrolled, including 105 males (66.46%), 95 patients with good outcome (60.1%) and 63 with poor outcome (39.9%). The age, total cholesterol, triglyceride, low-density lipoprotein cholesterol, baseline National Institutes of Health Stroke Scale (NIHSS) score, serum miR-143 and miR-182 level in the poor outcome group were significantly higher than those in the good outcome group (all P<0.05). Multivariate logistic regression analysis showed that age (odds ratio [ OR] 1.984, 95% confidence interval [ CI] 1.315-3.617; P=0.036), low-density lipoprotein cholesterol ( OR 2.108, 95% CI 1.406-4.103; P=0.013), baseline NIHSS score ( OR 2.584, 95% CI 1.675-4.505; P=0.005), miR-143 ( OR 3.205, 95% CI 2.370-6.180; P<0.001) and miR-182 ( OR 2.802, 95% CI 1.905-5.516; P<0.001) were the independent risk factors for poor outcomes in patients with AIS. ROC curve analysis showed that the combined area under the curve of miR-143 and miR-182 to predict the poor outcome in patients with AIS was 0.935 (95% CI 0.873-0.992), the sensitivity and specificity were 96.5% and 87.0% respectively. Conclusions:The increase of serum miR-143 and miR-182 was closely associated with the poor short-term outcomes in patients with AIS. The combination of the two has a good predictive value for the poor short-term outcomes in patients with AIS.

Objective:To investigate the expressions of serum microRNA-24 (miR-24) and microRNA-29b (miR-29b) in elderly patients with acute ischemic stroke (AIS) and their neural function prognostic value.Methods:A prospective study was conducted. 170 elderly patients with AIS admitted to department of neurology of Danzhou People's Hospital from January 1st, 2017 to March 31st, 2019 were enrolled. According to modified Rankin scale (mRS) score, the patients were divided into good neural function prognosis group (mRS score ≤ 2, n = 105) and poor neural function prognosis group (mRS score > 2, n = 65). According to National Institutes of Health stroke scale (NIHSS) score, the patients were divided into mild group (NIHSS score < 5, n = 50), moderate group (NIHSS score 5-20, n = 76) and severe group (NIHSS score > 20, n = 44). Sixty-five healthy volunteers in the same period were enrolled as the control group. The expressions of serum miR-24 and miR-29b were determined by real-time fluorescent quantitative reverse transcription-polymerase chain reaction (RT-qPCR). Receiver operating characteristic (ROC) curve was plotted to analyze the value of serum expressions of miR-24 and miR-29b for predicting the poor neural function prognosis of elderly patients with AIS. Pearson correlation was used to analyze the correlation between the expressions of serum miR-24, miR-29b and NIHSS, mRS scores in elderly patients with AIS. Results:The expressions of serum miR-24 and miR-29b in the AIS group were significantly lower than those in the healthy control group [miR-24 (2 -ΔΔCt): 0.64±0.17 vs. 2.18±0.85, miR-29b (2 -ΔΔCt): 0.72±0.21 vs. 3.05±0.96, both P < 0.01]. The expressions of serum miR-24 and miR-29b in the poor neural function prognosis group were significantly lower than those in the good neural function prognosis group [miR-24 (2 -ΔΔCt): 0.20±0.05 vs. 1.16±0.48, miR-29b (2 -ΔΔCt): 0.18±0.03 vs. 1.41±0.56, both P < 0.01]. The expressions of serum miR-24 and miR-29b in the severe group were significantly lower than those in the mild and moderate groups [miR-24 (2 -ΔΔCt): 0.13±0.02 vs. 1.30±0.51, 0.56±0.14; miR-29b (2 -ΔΔCt): 0.09±0.01 vs. 1.52±0.60, 0.62±0.13; all P < 0.01], and they were significantly lower in the moderate group than those in the mild group (all P < 0.01). ROC curve analysis showed that the optimal cut-off values of serum miR-24 and miR-29b expressions for predicting poor neural function prognosis in elderly AIS patients were 0.53 and 0.48, respectively. The area under ROC curve (AUC) of the two combined prognoses was 0.920 [95% confidence interval (95% CI) was 0.861-0.982], and it was significantly higher than that of miR-24 (AUC was 0.802, 95% CI was 0.742-0.860) or miR-29b (AUC was 0.835, 95% CI was 0.778-0.890) alone ( Z values were 6.513 and 4.902, respectively, both P < 0.05), with sensitivity and specificity of 92.0% and 85.7%. Pearson correlation analysis showed that the expressions of serum miR-24 and miR-29b were negatively correlated with NIHSS score ( r values were -0.758 and -0.794, respectively) and mRS score ( r values were -0.817 and -0.860, respectively) in elderly AIS patients (all P < 0.01). Conclusion:The down-regulated expressions of serum miR-24 and miR-29b are correlated with the severity degree of neurological impairment and neural function prognosis of elderly AIS patients, and the two combined have certain value for predicting the neural function prognosis of elderly AIS patients.

A score of 0-2 was defined as a good outcome and a score of >2 were defined as a poor outcome. Multivariate logistic regression analysis was used to determine the independent risk factors for poor outcome of patients with AIS. Receiver operating characteristic (ROC) curve analysis was used to determine the predictive value of serum miR-195 and miR-599 for the poor outcome of patients with AIS. Results:A total of 158 patients with AIS were enrolled. Their age was (65.80±12.36) years old, 105 were males (66.46); 95 patients (60.1%) had a good outcome, and 63 patients (39.9%) had a poor outcome. The age, total cholesterol, triglycerides, low-density lipoprotein cholesterol, baseline National Institutes of Health Stroke Scale (NIHSS) score, serum miR-195 and miR-599 levels in the poor outcome group were significantly higher than those of the good outcome group ( P<0.05). Multivariate logistic regression analysis showed that age (odds ratio [ OR] 1.984, 95% confidence interval [ CI] 1.315-3.617; P=0.036), low-density lipoprotein cholesterol ( OR 2.108, 95% CI 1.406-4.103; P=0.013), baseline NIHSS score ( OR 2.584, 95% CI 1.675-4.505; P=0.005), serum miR-195 ( OR 3.927, 95% CI 2.615-8.227; P<0.001) and miR-599 ( OR 2.952, 95% CI 1.973-6.114; P<0.001) were the independent risk factors for the poor outcome of patients with AIS. ROC curve analysis showed that the area under the curve (0.938, 95% CI 0.882-0.997) of serum miR-195 combined with miR-599 for predicting poor outcome was significantly higher than that predicted alone, and its predictive sensitivity and specificity were 97.0% and 87.4% respectively. Conclusions:The higher levels of serum miR-195 and miR-599 are associated with the poor outcome of patients with AIS. The combination of the both had good predictive value for the poor outcome of patients with AIS.

Objective:To design a replaceable corneal scaler and explore its effect on improving the positive detection rate of corneal bacteria and the cure rate of patients with infectious keratitis.Methods:Totally 100 patients with infectious keratitis treated in the Eye&Ent Hospital of Fudan University in Shanghai from June 2020 to October 2021 were conveniently selected as the application object, 50 patients from June 2020 to January 2021 were selected as the control group, and 50 patients from February 2021 to October 2021 were selected as the experimental group. The control group used the traditional corneal scalpel for corneal scraping, and the experimental group used the replaceable corneal scalpel for corneal scraping. The positive detection rate of bacteria, the cure rate of patients as of the date of data collection, the comfort status of patients and the operation difficulty score of medical staff were compared between the two groups.Results:The 28 cases (56%) were positive in the experimental group, and 30 cases (60%) were cured as of the date of data collection; 16 cases (32%) were positive in the control group and 18 cases (36%) were cured as of the date of data collection. The difference between the two groups was statistically significant ( χ2=-2.47, -2.20, all P<0.05). The score of comfort in the experimental group was (83.92 ± 6.40) and that in the control group was (54.04 ± 10.69). The difference between the two groups was statistically significant ( t=17.14, P<0.01). The operation difficulty score of medical staff in the experimental group was (1.46 ± 0.54) and that of medical staff in the control group was (3.24 ± 0.72). The difference between the two groups was statistically significant ( t=-13.50, P<0.01). Conclusions:The use of replaceable corneal scalpel can not only improve the positive detection rate of patients, improve the treatment effect of patients, improve the comfort and satisfaction of patients, but also improve the work efficiency of medical staff and reduce the operational risk of medical staff, so as to improve the real professional value of medical staff.

ObjectiveTo discuss the characteristics of psychological assistance hotline calls and operators' coping strategies of before and after the COVID-19 outbreak, in order to further improve the assistance ability of the psychological crisis hotline. MethodsA retrospective study was conducted on the demographics characteristics, call problems, coping strategies, and call time trends recorded by Changchun psychological assistance hotline information registration platform before the epidemic in Changchun City (January 20, 2019-April 20, 2019) and during the epidemic period (January 20, 2020-April 20, 2020). ResultsThe differences between gender, age, marital status, location, and occupation type before and during the epidemic were statistically significant (χ2=11.205, 234.240, 152.083, 265.458, 353.385, P<0.01). The number of different help calls had a statistically significant difference before and during the epidemic (χ2=185.088,P<0.01). The difference in the number of operators’ different coping strategies before and during the epidemic was statistically significant (χ2=226.810, P<0.01). Before the epidemic, the main peak of incoming calls was concentrated at 16∶00 to 17∶00, and the secondary peak was concentrated at 22∶00 to 23∶00. During the epidemic, the main peak of incoming calls was also concentrated at 16∶00 to 17∶00, while the secondary peak was concentrated at 10∶00 to 11∶00. ConclusionDuring the COVID-19 epidemic, the number of calls to the psychological assistance hotline was higher than that before the outbreak. The main peak time for calls was the same, and the secondary peak was adjusted from 22∶00 to 23∶00 to 10∶00 to 11∶00. During the epidemic, the number of calls from male, 30 to 39 years old, married, local and staff in Changchun was the most, psychological problems counseling and operator referral strategy were the most before and after the epidemic.
