Objective To investigate the clinical value of postoperative platelet-to-neutrophil ratio(PNR)in predicting the prognosis of patients with acute anterior circulation cardiogenic large-vessel occlusion stroke after receiving endovascular treatment.Methods A total of 95 patients with acute anterior circulation cardiogenic large-vessel occlusion stroke,who were admitted to the Affiliated Huai'an No.1 People's Hospital of Nanjing Medical University of China from January 2019 to January 2022,were enrolled in this study.Venous blood sampling was performed at admission and within 24 hours after thrombectomy,and the PNR,platelet-white blood cell ratio(PWR),platelet-lymphocyte ratio(PLR),and neutrophil-lymphocyte ratio(NLR)were calculated.According to the modified Rankin Scale score at 90 days(mRS-90),the patients were divided into good prognosis group(mRS-90 ≤2 points,n=45)and poor prognosis group(mRS-90 3-6 points,n=50).The clinical data were compared between the two groups.Multivariate logistic regression analysis was used to analyze the predictors of 90-d good prognosis.The area under the receiver operating characteristic curve(AUC)was used to compare the efficacy of PWR,PNR,and NLR in predicting good prognosis.Results Compared with poor prognosis group,in good prognosis group the patients were younger,the NIHSS score at admission was smaller,the incidence of postoperative contrast extravasation was lower,the postoperative 24-hour PWR and PNR values were higher,and the postoperative 24-hour NLR value was lower,the differences in the above indexes between the two groups were statistically significant(all P＜0.05).Multivariate analysis showed that bridging therapy(OR=4.746,P=0.021,95％CI:1.262-17.856),postoperative contrast medium extravasation(OR=0.254,P=0.022,95％CI:0.079-0.824)and postoperative 24-h PNR(OR=1.087,P=0.006,95％CI:1.025-1.153)were the independent predictors for 90-d good prognosis in patients with acute anterior circulation cardiogenic large-vessel occlusion stroke after receiving endovascular treatment.AUCs of postoperative 24-h PWR,PNR and NLR for predicting a good prognosis after thrombectomy were 0.734,0.736 and 0.704 respectively.PNR had the highest predictive efficacy,with a cutoff value of 25.08,a specificity of 84.00％,and a sensitivity of 67.78％.Conclusion In patients with acute anterior circulation cardiogenic large-vessel occlusion stroke after receiving endovascular treatment,a better clinical prognosis can be expected when the patient has a higher postoperative 24-h PNR value.

Objective:To investigate the effect of intravenous thrombolysis with recombinant tissue plasminogen activator (rt-PA) on sizes and components of thrombi in patients with acute ischemic stroke (AIS) after mechanical thrombectomy (MT).Methods:Ninety-eight AIS patients accepted MT in Department of Neurology, Huaian First Hospital Affiliated to Nanjing Medical University from June 2018 to June 2022 were enrolled; they were divided into bridging therapy group and direct thrombectomy group according to the treatments. Baseline data, prognoses and thrombus features between the 2 groups were compared.Results:No significant differences were observed between the 2 groups in terms of age, gender, previous medical history, baseline scores, sites and types of vascular occlusion, TOAST causative classifications, time frame, MT frequencies and techniques, successful recanalization, or prognoses 90 d after MT ( P>0.05). Compared with the direct thrombectomy group, the bridging therapy group had significantly reduced thrombus area (37[22, 78] mm 2vs. 27[14, 62] mm 2) and areas of major pathological components [red blood cells: 16.1([9.0, 37.4] mm 2vs. 11.8[6.1, 22.1] mm 2, fibrin/platelets: 19.5[9.5, 26.4] mm 2vs. 10.7[5.0, 22.8] mm 2, white blood cells: 4.0[2.2, 8.0] mm 2vs. 2.4[1.4, 5.7] mm 2, P<0.05); however, no significant differences in proportions of areas of major pathological components were noted between the 2 groups of patients ( P>0.05). Conclusion:The rt-PA intravenous thrombolysis can significantly reduce the thrombi volume and decrease the contents of major thrombus components in AIS patients after MT, but not change the proportions of major pathological components in thrombi.

Objective:To explore the effect of perioperative nursing based on enhanced recovery after surgery (ERAS) in patients undergoing off-pump coronary artery bypass (OPCAB) .Methods:From January 2018 to February 2020, 200 OPCAB patients admitted to Affiliated Hospital of Jining Medical University were selected as research subjects using convenience sampling method. The 100 patients admitted from January 2018 to January 2019 served as the control group, while the 100 patients admitted from February 2019 to February 2020 served as the observation group. The control group received routine perioperative nursing, while the observation group received perioperative nursing based on the ERAS. The postoperative ventilator assistance time, Intensive Care Unit (ICU) stay time, anal exhaust time, off-bed time after surgery, and postoperative hospital stay time were compared.Results:The observation group had shorter postoperative ventilator assistance time, ICU stay time, anal exhaust time, off-bed time after surgery, and postoperative hospital stay time compared to the control group, with statistically significant differences ( P<0.05) . Conclusions:Perioperative nursing based on the ERAS can accelerate the postoperative recovery process of OPCAB patients, which is worthy of clinical promotion and practice.

In China, the survival rate of liver cancer remains low while the mortality rate is high. Effectively reducing the burden of liver cancer is still a major challenge in the field of public health and chronic disease prevention in the Chinese population. Optimizing screening strategies for liver cancer remains a profound approach to secondary prevention worthy of continuous explora-tion. This guideline was commissioned by the Bureau of Disease Control and Prevention of the National Health Commission. The National Cancer Center of China initiated the guideline develop-ment and convened a multidisciplinary expert panel and working group. Following the World Health Organization Handbook for Guideline Development, this guideline integrated the most up-to-date evidence of liver cancer screening, China′s national conditions, and existing practical experience in liver cancer screening. Evidence-based recommendations on the target population, screening technologies, surveillance strategies, and other key points across the process of liver cancer screening and surveillance management were provided. This guideline would help to standardize the practice of liver cancer screening in China.

Objective:To evaluate the association between thrombus composition and mechanical recanalization,operation procedure and clinical outcome.Methods:One hundred and ninety-two consecutive stroke patients with large-vessel occlusion treated by mechanical thrombectomy using a stent retriever and (or) aspiration catheter in the Affiliated Huaian No.1 People′s Hospital of Nanjing Medical University between January 2018 and January 2020 were collected. The retrieved thrombi were quantitatively analyzed for red blood cells, white blood cells, platelets, and fibrin. The patients were divided into two groups, a erythrocyte-rich group and a fibrin-rich group based on the predominant composition in the clot. The clinical prognosis, CT value of thrombus, procedure time,number of recanalization maneuvers, and degree of vascular recanalization were compared between the two groups.Results:The retrieved clot from 138 patients with acute ischemic stroke from internal carotid artery occlusion ( n=56), middle cerebral artery occlusion ( n=62), intracranial segment of vertebral artery or basilar artery occlusion( n=20) were histologically analyzed. Erythrocyte-rich clots were present in 59 cases, while fibrin-rich clots were present in 79 cases. Cardioembolic thrombi had higher proportions of fibrin/platelets [77.2%(61/79)], less erythrocytes than noncardioembolic thrombi [45.8%(27/59), χ2=8.115, P=0.004]. Patients with erythrocyte-rich thrombi had a smaller number of recanalization maneuvers [2 (1, 2) vs 3 (2, 4), Z=-7.613, P<0.001], shorter procedure time [45 (30, 60) min vs 80 (60, 90) min, Z=-6.944, P<0.001], higher thrombus CT value [42 (32, 53) vs 36 (31, 41), Z=-2.003, P=0.045], good clinical prognosis (the ratio of modified Rankin Scale score ≤2, 62.7% (37/59) vs 39.2% (31/79), χ2=7.444, P=0.006). There was no significant difference in the location of vascular occlusion between the two groups. Conclusion:For patients whose thrombotic components are mainly red blood cells, the cause of stroke may be non cardiogenic cerebral embolism, the CT value of embolus is relatively high, the embolus is easy to remove, and the clinical prognosis is relatively good.

Pediatric cough is a heterogeneous condition in terms of symptoms and the underlying disease mechanisms. Symptom phenotypes hold complicated interactions between each other to form an intricate network structure. This study aims to investigate whether the network structure of pediatric cough symptoms is associated with the prognosis and outcome of patients. A total of 384 cases were derived from the electronic medical records of a highly experienced traditional Chinese medicine (TCM) physician. The data were divided into two groups according to the therapeutic effect, namely, an invalid group (group A with 40 cases of poor efficacy) and a valid group (group B with 344 cases of good efficacy). Several well-established analysis methods, namely, statistical test, correlation analysis, and complex network analysis, were used to analyze the data. This study reports that symptom networks of patients with pediatric cough are related to the effectiveness of treatment: a dense network of symptoms is associated with great difficulty in treatment. Interventions with the most different symptoms in the symptom network may have improved therapeutic effects.

Objective:To investigate the relations of thrombotic components with cause of stroke, procedure of mechanical thrombectomy, degrees of vascular recanalization and clinical prognoses in patients with large vessel occlusive cerebral infarction.Methods:One hundred and thirty-eight patients with large vessel occlusive cerebral infarction accepted mechanical thrombectomy using stent retriever and/or aspiration catheter in our hospital from January 2018 to January 2020 were chosen. These patients were divided into two groups, a erythrocyte-rich group and a fibrin-rich group, based on the predominant composition in the clots. The baseline clinical data, procedure time, number of recanalization maneuvers, degrees of vascular recanalization and clinical prognoses were compared between the two groups. The relations of infiltration degrees of erythrocytes and fibrin in embolus with procedure time were investigated.Results:The components of thrombus clots were mainly erythrocytes, fibrin, leukocytes, and platelets; erythrocyte-rich clots were presented in 59 patients, and fibrin-rich clots were presented in 79 patients. There was no significant difference in age, gender, preoperative NIHSS scores, proportions of hypertension, proportion of diabetes and proportion of vascular recanalization between the two groups ( P>0.05). As compared with patients from erythrocyterich group, patients in the fibrin-rich group had significantly higher proportion of cardioembolic thrombus (22.8% vs. 77.2%), statically larger number of recanalization maneuvers (2 [1, 2] times vs. 3 [2, 4] times), significantly longer procedure times (45 [30, 60] min vs. 80 [60, 90] min), and significantly lower proportion of patients with modifed Rankin scale (mRS) scores≤2 90 d after surgery (62.7% vs. 39.2%, P<0.05). Procedure time was negatively correlated with erythrocyte infiltration ( r= -0.562, P=0.005) and positively correlated with fibrin infiltration ( r=0.567, P=0.010). Conclusions:Different components of thrombus suggest the etiology of stroke may be different. Thrombus removal is relatively easy in patients with erythrocyte-rich clots, and the clinical prognosis is relatively good.
