Objective:To investigate the cardiac presentations and the possible influencing factors of severe and critical coronavirus disease 2019 (COVID-19).Methods:A retrospective study was conducted. Patients with severe and critical COVID-19 admitted to the Eighth People's Hospital of Guangzhou from January 21st to February 24th 2020 were enrolled. According to the clinical classification, the patients were divided into severe group and critical group. The myocardial injury markers, such as lactate dehydrogenase (LDH), aspartate aminotransferase (AST), creatine kinase (CK), cardiac troponin I (cTnI), myoglobin (MYO), MB isoenzyme of creatine kinase (CK-MB), B-type natriuretic peptide (BNP) and electrocardiogram (ECG) changes were compared between the two groups.Results:A total of 55 COVID-19 patients were selected, including 15 critical cases and 40 severe cases. The patients with severe and critical COVID-19 were male-dominated (61.8%), the average age was (61.2±13.0) years old, 83.6% (46 cases) of them had contact history of Hubei, 38.2% (21 cases) of them were complicated with hypertension. There was no significant difference in baseline data between the critical group and the severe group. Myocardial injury markers of critical and severe COVID-19 patients were increased in different proportion, LDH increased in most patients (20 severe cases and 7 critical cases), followed by AST (16 severe cases and 5 critical cases). There was significant difference in the number of patients with elevated CK between severe group and critical group (cases: 1 vs. 4, P = 0.027). Abnormal ECG was found in 39 of 42 patients with ECG examination. Nonspecific change of T wave was the most common. Before and after treatment, 9 of 15 patients with changes of ECG and myocardial injury markers had oxygenation index less than 100 mmHg (1 mmHg = 0.133 kPa), and the prominent changes of ECG were heart rate increasing and ST-T change. Conclusions:The increase of myocardial injury markers and abnormal ECG were not specific to the myocardial injury of severe and critical COVID-19 patients. At the same time, the dynamic changes of myocardial injury markers and ECG could reflect the situation of myocardial damage.

Objective:To formulate a ladder type early activity program in order to provide a theoretical and practical basis for improving the current activity status of tumor patients with pulmonary embolism.Methods:This research was conducted experimentally. A total of 92 tumor patients diagnosed as pulmonary embolism from January 1, 2021 to March 31, 2022 in Sichuan Cancer Hospital were divided into control group and experimental group with 46 cases each by random number table method. In the control group, a routine activity program was carried out, and the patients were confined to bed for 7 days. The experimental group obtained the best evidence of early pulmonary embolism activity plan through evidence-based nursing, formed a nurse-led ladder type early pulmonary embolism activity team, and finally constructed and implemented the ladder type early activity plan. The mortality rate, new thrombosis in ICU for 3 days and 7 days, length of stay in ICU and patients′ comfort were compared between the two groups.Results:The mortality rates within 30 days after the diagnosis of pulmonary embolism were 4.35% (2/46) and 2.17% (1/46) respectively in the control group and the experimental group, with no significant difference between the two groups ( χ2=0.35, P>0.05). The rates of new thrombosis were 15.22% (7/46) and 26.09% (12/46) in the control group, and 4.35% (2/46) and 4.35% (2/46) in the experimental group, respectively at 3 and 7 days after ICU admission, with a significant difference between the two groups at 7 days after ICU admission ( χ2=8.43, P<0.05). The length of stay in ICU and the score of General Comfort Questionnaire (GCQ) were (15.74 ± 11.11) days and (64.30 ± 15.54) points in the experimental group, respectively, while those in the control group were (11.07 ± 5.63)days and (73.84 ± 11.73) points, respectively. The difference between the two groups was statistically significant ( t=-2.55, -3.32, both P<0.05). Conclusions:The evidence-based ladder type early activity program for patients with pulmonary embolism caused by tumor will not increase the mortality of patients, but can ensure the safety of patients, reduce the incidence of new thrombosis and the length of ICU stay, improve the comfort of patients during the treatment of pulmonary embolism. It is worthy of clinical application.

Objective To assess the efficacy and safety of morinidazole combined with appendectomy in treating purulent or gangrenous appendicitis.Methods Double-blind randomized controlled multicenter clinical trial was designed and conducted.Totally 437 patients were included,219 in the control group and 218 in the experimental group.Cases of purulent or gangrenous appendicitis were enrolled and assigned to each of the two groups.The control group received ornidazole injection for 5 to 7 days while the experimental group received morinidazole injection.Both groups underwent appendectomy.Clinical response,micrombiological outcomes,overall response were evaluated.Adverse events and side effects were recorded.Results No significant difference was observed between the two groups regarding the clinical healing rate at 5-10 days after medicine withdrawal,anaerobia clearance and overall healing rates.Adverse events occurred in 140 patients (32.1%).Incidence of adverse events in the control group and the experimental group was 34.7% and 29.4%,respectively (P > 0.05).The overall incidence of side effects was 15.1% (66 cases).Side effects were less seen in the experimental group compared with that in the control group (11.5% vs.18.7%,P < 0.05).The most frequent side effects were aminotransferase rising,thrombocytosis,nausea,vomiting and electrocardiographic abnormality.Conclusions The effect of morinidazole plus operation was comparable with ornidazole in treating purulent or gangrenous appendicitis.The safety of morinidazole is better than ornidazole.

Objective To investigate the clinical characteristics of patients with acute myocardial infarction (AMI) complicated with cardiac rupture (CR) and to explore the risk factors for the survival time of AMI combined with CR. Methods A retrospective study was conducted. The clinical data of 75 hospitalized patients with the confirmed diagnosis of AMI combined with free wall rupture (FWR) or ventricular septal rupture (VSR) admitted to Guangdong General Hospital from April 2009 to March 2015 were collected. They were divided into a survival < 30-day group (42 cases) and a survival ≥ 30-day (33 cases) group, and their clinical characteristics were analyzed. Receiver operating characteristic curve (ROC curve) was drawn, and the predictive value of each indicator for the patient's 30-day survival time was analyzed. Results The number of female patients (25 cases vs. 0 case) and the number of patients without diabetes (36 cases vs. 21 cases) in the survival < 30-day group were significantly higher than those in survival ≥ 30-day group (all P < 0.05). Therefore, both female and without diabetes were risk factors for the recent death of AMI complicated with CR. In the survival ≥ 30-day group, the number of patients with right coronary artery (RCA) lesions and immediately undergoing early percutaneous coronary intervention therapy (PCI) was significantly higher than that in survival < 30-day group (11 cases vs. 4 cases, P < 0.05). Therefore, the RCA lesion and immediately undergoing early PCI therapy was a recent survival protective factor. ROC curve analysis showed that AMI female and combined with diabetes and lesions in RCA had a certain predictive value for survival time of the patients, the area under ROC curve (AUC) and 95% confidence interval (95%CI) were 0.798 (0.696-0.899), 0.592 (0.542-0.743) and 0.647 (0.500-0.794) respectively, sensitivity and specificity were 34.6%, 16.1% and 42.3% and 12.9% respectively, all P < 0.05. Conclusions Women and without diabetes are the risk factors of recent death of AMI complicated by CR, and in patients with AMI complicated with CR and the involved lesion being RCA, PCI therapy should be performed as early as possible that may elevate the 30-day survival rate for the patients.
