Debates persist regarding the efficacy and safety of azvudine, particularly its real-world outcomes. This study involved patients aged ≥60 years who were admitted to 25 hospitals in mainland China with confirmed SARS-CoV-2 infection between December 1, 2022, and February 28, 2023. Efficacy outcomes were all-cause mortality during hospitalization, the proportion of patients discharged with recovery, time to nucleic acid-negative conversion (T _NANC), time to symptom improvement (T _SI), and time of hospital stay (T _HS). Safety was also assessed. Among the 5884 participants identified, 1999 received azvudine, and 1999 matched controls were included after exclusion and propensity score matching. Azvudine recipients exhibited lower all-cause mortality compared with controls in the overall population (13.3% vs. 17.1%, RR, 0.78; 95% CI, 0.67-0.90; P = 0.001) and in the severe subgroup (25.7% vs. 33.7%; RR, 0.76; 95% CI, 0.66-0.88; P < 0.001). A higher proportion of patients discharged with recovery, and a shorter T _NANC were associated with azvudine recipients, especially in the severe subgroup. The incidence of adverse events in azvudine recipients was comparable to that in the control group (2.3% vs. 1.7%, P = 0.170). In conclusion, azvudine showed efficacy and safety in older patients hospitalized with COVID-19 during the SARS-CoV-2 omicron wave in China.

Objective:To observe any effect of intermittent theta burst stimulation (iTBS) on the spatially-delayed responses of working memory using cynomolgus macaques.Methods:The working memory of six male cynomolgus macaques (8-9 years old) was trained using a spatially-delayed response task. They were then randomly divided into an iTBS group and a control group, each of 3. The iTBS group was given iTBS at an intensity of 35% of the maximum output, with 2 seconds of stimulation followed by 8 seconds of rest with trains of 50Hz bursts repeated at a frequency of 5Hz over a period of 192 seconds once daily for 5 days, while the control group was given sham iTBS. Before and after the 5 days, the body weight and working memory of each animal were evaluated. The total number of effective feeding episodes, and of effective feeding episodes with short and long delay periods were recorded.Results:There was no significant change in the average body weight of either group before and after the modeling and iTBS intervention. After the intervention the number of total effective feeding cases and those with a short delay period were both significantly higher in the iTBS group than in the control group. However, no significant inter-group differences in the effective feeding cases with a long delay period were observed.Conclusions:iTBS is effective in improving the spatially-delayed responses of working memory, at least in cynomolgus macaques.

Objective To analyze the feasibility of six-minute walk test (6MWT) before pulmonary lobectomy and prediction for postoperative outcome. Methods A total of 580 patients who were hospitalized in the department of lung surgery from May, 2017 to May, 2019 were reviewed, and 274 eligible patients were selected, who underwent first surgery and the surgical method was pulmonary lobectomy. They were divided into two groups based on the results of 6MWT before operation. The cut-off value of six-minute walk distance (6MWD) was obtained by receiver operating characteristic curve (ROC) area under curve (AUC). The postoperative outcome and the occurrence of cardiopulmonary complications in the two groups were analyzed. Results Compared to patients with 6MWD > 449 meters, the age was significantly older (P < 0.001), the forced expiratory volume in the first second (FEV1) was poor in patients with 6MWD ≤ 449 meters (P < 0.05), and other factors such as surgical resection site, pathological stage, gender, etc., were not significantly different (P > 0.05). The incidence of postoperative cardiopulmonary complications was significantly higher (OR = 2.672, 95%CI 1.488 to 4.798, P = 0.002), and the postoperative extubation time and hospital stay was longer in patients with 6MWD ≤ 449 meters than in patients with 6MWD > 449 meters (P < 0.05). 6MWD ≤ 449 meters was an independent risk factor for postoperative cardiopulmonary complications (OR = 2.395, 95%CI 1.299 to 4.415, P = 0.005). Conclusion As a simple function test, 6MWT can be routinely used to assess the physiological function of patients undergoing pulmonary lobectomy. Patients with 6MWD ≤ 449 meters may be in higher risks of postoperative cardiopulmonary complications.

Sepsis is caused by the imbalance of the host body's response to infection, which causes life-threatening organ dysfunction. Disorders of blood coagulation play a very important role in the development of sepsis. In sepsis, the body's coagulation system is activated, leading to hypercoagulability, while the anticoagulation mechanism is significantly inhibited, causing a large number of microthrombi to form, and disseminated intravascular coagulation (DIC) may occur. Although there are obvious controversies about the anticoagulation treatment of sepsis at home and abroad, we cannot deny the significance of anticoagulation treatment in sepsis. Only appropriate anticoagulation can effectively reduce the mortality in septic DIC, septic shock and high-risk population, and ultimately effectively reduce the occurrence of multiple organ dysfunction syndrome. The sepsis-induced coagulation dysfunction (SIC) score is currently used internationally to guide anticoagulation. SIC score is optimized based on the International Society on Thrombosis and Haemostasis (ISTH) overt DIC score and Sepsis-3, including platelet, international normalized ratio (INR) and sequential organ failure assessment (SOFA). The SIC score can sensitively monitor sepsis-induced coagulation dysfunction. When the SIC score is≥4, it is the best timing to initiate anticoagulation therapy. At present, the internationally recommended anticoagulant drugs include antithrombin (AT), thrombomodulin (TM), tissue factor pathway inhibitor (TFPI), heparin, etc., while the domestically recommended anticoagulant drugs are only unfractionated heparin and low molecular weight heparin. Before using anticoagulant drugs, it is necessary to evaluate the possibility of bleeding and thrombosis in the patients. At the same time, it is necessary to pay attention to the patient's primary disease. Try to adopt the treatment strategy of transitioning from unfractionated heparin to low molecular weight heparin without obvious anticoagulation contraindications.

Objective:To explore the influencing factors of self-management of diabetics in community so as to provide a scientific basis for personalized self-management of diabetics.Methods:From March 2016 to August 2017, this study selected 980 diabetics from 6 communities in Chaoyang District of Beijing by convenience sampling. All of patients were investigated with the self-management, nursing instruction need and medication adherence questionnaire and the medication adherence scale to understand the self-management, such as blood glucose management, exercise, medication adherence and nursing instruction need. Simple correlation and multiple regression were used to analyze the influencing factors of self-management, nursing instruction need and medication adherence.Results:Among those diabetics in community, the score of self-management was (1.76±0.25) . The score of nursing instruction need was (1.73±0.29) with medication instruction need dimension for the highest and diabetic knowledge instruction need dimension for the lowest. The score of medication adherence was (3.48±0.64) with unauthorized drug withdrawal dimension for the highest and times of taking medicine dimension for the lowest. Simple correlation showed that there were statistical differences in the scores of self-management among patients with different on-the-job situations and education levels ( P<0.05) , and in the score of nursing instruction need among patients with different education levels ( P<0.05) , and in the scores of medication adherence among patients with different ages, on-the-job situations and diagnosed ages ( P<0.05) . Multiple regression analysis showed that the influencing factor of self-management and nursing instruction need was the education level ( P<0.05) , and the influencing factor of self-management was the on-the-job situation ( P<0.05) , and the influencing factor of medication adherence was the age ( P<0.05) . Conclusions:Among diabetics in community, the self-management is influenced by the education level and on-the-job situation; nursing instruction need is influenced by the education level; the medication adherence is influenced by the age. We should increase the self-management of patients with the low level of education and on-the-job, provide nursing instruction for patients with the high level of education, promote the medication adherence of diabetics with low ages so as to improve the self-management and quality of life of patients.

Objective To investigate the influencing factors of self-care status of patients with hypertension in communities, so as to provide scientific evidences for personal self-care management of hypertension patients. Methods From March 2016 to August 2017, 1 010 hypertensive patients from 6 communities in Chaoyang District of Beijing were surveyed using general data questionnaire, Self-care Status and Nursing Guidance Needs Questionnaire and Medication Compliance Scale, to analyze the influencing factors of self-care status. Results In the 1 010 cases of hypertension patients in community, the score of self-care status was (1.70±0.22), the score of the demand of nursing education was (1.69±0.33), and the score of medication compliance was (3.54±0.58). The differences in the score of self-care status of patients with different education level and different years of hypertension diagnosis were statistically significant (P＜0.05). There were significant differences in the scores of nursing guidance needs among patients of different ages and educational backgrounds (P＜0.05). There were significant differences in the scores of medication compliance among patients of different ages, occupations and years of hypertension diagnosis (P＜0.05). Multivariate linear regression analysis showed that age, education level, years of hypertension diagnosis and occupation were the influencing factors of self-care status of patients. Conclusions Self-care status of hypertensive patients are affected by age, education level, years of diagnosis and occupations. The personal health education and guidance should be given based on patients' different social background, so as to enhance the level of self-care status and improve the patients' life quality.

Objective To study the correlations of anxiety and depression at different phases with curative outcomes in female patients at IVF-ET cycle.Methods One hundred and seventeen patients were involved the study using the Self-Rating Anxiety Scale (SAS), Self-Rating Depression(SDS)questionnaires when registered for IVF-ET cycle(T1), one day prior to oocyte retrieval(T2), and 5 to 7 days after embryo transfer(T3).SDS scores and SAS scores were compared between different phases.Logistic regression was used to analyze the correlation of SAS scores with outcome.Results SDS scores of T1, T2 and T3 phases showed no significant differences(all P<0.05).The SAS scores at T2 and T3 were higher than that at T1(all P<0.05), the SAS scores at T2 were higher than that at T3(P<0.05).The SAS scores at T2 in patients achieved clinical pregnancy were significantly lower than that in patients achieved no clinical pregnancy.Logistic regression model showed that lower SAS scores were associated with higher pregnancy rates (P<0.05).Conclusions Anxiety level is the most remarkable one in the phase prior to oocyte retrieval.Low anxiety level prior to oocyte retrieval predicts higher a pregnancy rate.

BACKGROUND:Most stroke patients affected walking dysfunction. Virtual reality-enhanced body weight-supported treadmil training has been proposed as a strategy for gait training of cerebral infarction subjects.
OBJECTIVE:To evaluate the effectiveness of virtual reality-enhanced body weight-supported treadmil training on lower limb motor function in subacute cerebral infarction patients.
METHODS:Twenty cerebral infarction patients (within 3 months of onset) were randomly divided into experiment group (virtual reality-enhanced body weight-supported treadmil training) and control group (conventional physiotherapy). Three-dimensional gait analysis in lower limb motor function was carried out before and after 3-week gait training. Intergroup and intragroup comparisons in the fol owing parameters were done before and after training:walking speed, cadence, step time, single limb support time (%), double limb support time (%), nonparetic swing (%), step length, pace, range of motion in the lower limb, functional ambulation category, Fugl-Meyer Assessment of the lower limbs and Brunel Balance Assessment.
RESULTS AND CONCLUSION:No significant differences in patient’s gender, age, course of disease, affected. side, walking speed, functional ambulation category, Fugl-Meyer Assessment of the lower limbs and Brunel Balance Assessment were detected between the two groups before training (P>0.05). Fugl-Meyer Assessment and functional ambulation category were improved in patients of the two groups after training (P<0.05). The improvement in walking speed, cadence, step time in affected side, step time in healthy side, single limb support time in affected side (%), nonparetic swing (%), pace, step lengths in affected and healthy sides were better in the experimental group than those in the control group.
