Rationale:Extensive thrombosis in the portal venous system caused by hypereosinophilic syndrome (HES) is rare, and there is no consensus on anticoagulant and thrombolytic treatments for arteriovenous thrombosis caused by HES.Patient concerns:The clinical data of a patient with extensive thrombosis in his portal venous system (superior mesenteric, splenic, hepatic, and portal veins), renal artery thrombosis, and mesenteric thrombosis caused by HES with secondary gastrointestinal bleeding and intestinal necrosis were retrospectively analyzed. Before admission, his eosinophil count increased to 7.47 × 109/L, and HES had been confirmed via bone marrow cytology. The patient experienced fever, cough, abdominal pain, massive hematemesis, and hematochezia that developed in succession. Abdominal computed tomography showed portal vein and superior mesenteric vein thromboses.Diagnosis:Hypereosinophilic syndrome; extensive thrombosis in the portal venous system; acute eosinophil-associated pneumonia; gastrointestinal bleeding; intestinal necrosis.Interventions:The patient was first treated with methylprednisolone, plasma exchange/hemofiltration, and single or combined use of unfractionated heparin and argatroban for anticoagulation. He was also administered alteplase and urokinase, successively, for thrombolytic treatment. Once the thromboses finally disappeared, the patient underwent surgery to excise a necrotic intestinal canal.Outcomes:The thromboses disappeared with these treatments, and the patient recovered after the necrotic intestinal canal was excised.Lessons:The clinical manifestations of HES are complex and varied, and this condition can cause severe and extensive arteriovenous thrombosis. Anticoagulation therapy and thrombolysis are necessary interventions, and appear to be safe and effective.

Background. The survey found that in recent years, with the incidence of chronic kidney disease (CKD) increasing, some patients with CKD even progressed to end-stage renal disease. Luckily, progressive hemodialysis technology and nursing level can improve the quality of life and prognosis of patients. Objective. To explore the application of plan-do-check-adjust (PDCA) cycle in the management of nurses in hemodialysis center and its effect on the maintenance of internal fistula in patients. Methods. In this study, a randomized controlled trail (RCT) was used to select 90 patients who underwent maintenance hemodialysis in the hemodialysis center of our hospital from January 2018 to June 2021 as objects. They were divided into a PDCA group (with PDCA nursing management) and routine group (with routine nursing management) by random number table with each of 45 cases for 6 months to compare the differences of the internal fistula complications, internal fistula maintenance quality, patients’ microinflammatory state, and satisfaction with nursing, as well as nursing staff’s operational and theoretical performance between the two groups. Results. There was no significant difference in CRP, IL-1, TNF-α, and IL-6 levels between the two groups before intervention ( P > 0.05 ); after that, these levels in the PDCA group were lower than those in the routine group, with statistically significant difference ( P < 0.05 ); before intervention, there was no statistically significant difference in the qualification rate of blood flow, the awareness rate of health education, and the incidence of nursing defects between the two groups ( P > 0.05 ); after that, the qualification rate of blood flow and the awareness rate of health education among nurses in PDCA group were higher than those in routine group, while the incidence of nursing defect accidents in the PDCA group was lower than that in routine group, and the differences were statistically significant ( P < 0.05 ); before intervention, there was no significant difference in the complication rate between the two groups ( P > 0.05 ); after that, the complication rate of the PDCA group was lower than that of the routine group, and the differences were statistically significant ( P < 0.05 ); after intervention, the theoretical assessment and practical skills assessment scores of the PDCA group were higher than those of the routine group, and the differences were statistically significant ( P < 0.05 ); after intervention, the nursing satisfaction of the PDCA group was higher than that of the routine group, and the differences were statistically significant ( P < 0.05 ). Conclusion. The application of PDCA approach in the management of nurses in hemodialysis centers can effectively improve the quality of internal fistula management and improve the practical and theoretical level of nurses, as well as reduce the microinflammation of patients.

Background. Septic shock is a common clinical critical disease with high mortality, hemodynamic instability, and easy to be complicated with multiple organ failure. The rapid progress of the patient’s condition poses a serious threat to patient’s safety. Aim. To investigate the relationship between the dynamic monitoring of microcirculation perfusion parameters and blood lactic acid level and the prognosis of patients with infection shock in ICU. Methods. A total of 104 patients with septic shock admitted to ICU of Affiliated Hai’an Hospital of Nantong University from February 2018 to June 2021 were selected for clinical research. According to the survival situation of patients after 28 days of treatment, they were divided into the death group (n = 48) and the survival group (n = 56). The central venous-arterial carbon dioxide partial pressure difference (Pcv-aCO2), the ratio of central venous-arterial carbon dioxide partial pressure difference to arterial central venous oxygen content difference (Pcv-aCO2/Ca-cvO2), and blood lactic acid level were retrospectively analyzed and compared between the two groups on the first, third, and seventh days after admission to ICU. The odds ratio (OR) of three indexes affecting the prognosis of patients with septic shock was analyzed by univariate and multivariate mathematical models, and the value of three indexes in predicting the prognosis of patients was analyzed by receiver operating curve (ROC). Results. Pcv-aCO2 and lactic acid in the death group were higher than those in the survival group on the 1st, 3rd, and 7th day of ICU stay ( P  < 0.05). The Pcv-aCO2/Ca-cvO2 of the death group was higher than that of the survival group on the 3rd and 7th day of ICU stay ( P  < 0.05). Logistic model results showed that age, SOFA score, APACHE II score, the number of multiple organ failure (MODS), intracranial infection, the increase of Pcv-aCO2, Pcv-aCO2/Ca-cvO2, and the increase of lactic acid were independent risk factors for death in patients with septic shock (OR values were 1.519, 1.808, 1.781, 1.912, 2.069, 1.848, 1.781, and 1.642, respectively, P  < 0.05). The results showed that the AUC value of Pcv-aCO2 in predicting death was 0.943, and the sensitivity and specificity were 93.72% and 83.09%, respectively. The AUC value of Pcv-aCO2/Ca-cvO2 for predicting death was 0.887, and the sensitivity and specificity were 81.63% and 77.56%, respectively. The AUC value of lactic acid in predicting death of patients was 0.825, and the sensitivity and specificity were 71.66% and 82.09%, respectively. Conclusion. Changes of microcirculation flow tissue perfusion parameters and blood lactic acid level changes are closely related to the prognosis of patients with septic shock, which is of great value in the evaluation of the prognosis of patients with septic shock.

ObjectiveThe purpose of this study was to assess the psychological status of medical workers from other locations who helped support the fight against COVID-19 in Shanghai and to provide a basis for psychological crisis intervention plans under designated emergencies.MethodsWhile supporting the Shanghai Lingang Shelter Hospital, we investigated 1,097 medical staff from other cities working in the hospital. A questionnaire comprising the general information questionnaire, health questionnaire depression scale, generalized anxiety scale, insomnia severity index scale, and mental health self-assessment questionnaire was used.ResultsThere were no statistically significant differences in the incidence rates of anxiety, depression, and sleep disorders among subjects of different genders, ages, and educational levels. There were statistically significant differences in the incidences of anxiety, depression, stress response, and sleep disturbance among subjects with different levels of worry about COVID-19.ConclusionDuring the COVID-19 pandemic, the Lingang Shelter Hospital team experienced more psychological pressure, suggesting that medical institutions should pay attention to the mental health of frontline medical workers during COVID-19 and prepare psychological intervention measures for team members.

Objective To evaluate the therapeutic effects of high-flow nasal cannula (HFNC) oxygen therapy in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and type II respiratory failure. Methods Seventy-two patients with AECOPD and type II respiratory failure were randomly allocated to an HFNC oxygen therapy trial group or a non-invasive positive-pressure ventilator therapy (NIPPV) control group. Their arterial blood gas parameters and comfort, evaluated using a questionnaire, were compared before and after the therapeutic interventions. Results The PaCO2 and blood [Formula: see text] concentration of both groups were significantly reduced by the treatments, whereas the pH, PaO2 and PaO2/FiO2 were increased. The PaCO2 of the experimental group was significantly lower than that of the control group following treatment. The PaO2 of the experimental group was significantly higher than that of the control group. The tracheal intubation rates of the two groups did not significantly differ. After treatment, all the indices of comfort were rated higher in the HFNC group than in the NIPPV group. Conclusions HFNC has a good therapeutic effect in patients with AECOPD and type II respiratory failure. It improves patient comfort and has clinical value.
