OBJECTIVE: To study the modulation of Jianjining Recipe (JJNR), a traditional Chinese compound herbal medicine for invigorating spleen and kidney on differential protein expression in spleen of rats with experimental autoimmune myasthenia gravis (EAMG). METHODS: EAMG rats were randomly divided into four groups: untreated group, JJNR-treated group, Qiangji Jianli capsule (QJJLC, a traditional Chinese compound herbal medicine)-treated group and prednisolone acetate (PA)-treated group. After therapeutic intervention with the above drugs for four consecutive weeks, the level of differential protein expression was analyzed by two-dimensional electrophoresis and matrix assisted laser desorption/ionization time-of-flight mass spectrometry. RESULTS: Twelve differential proteins were identified by comparing EAMG rats and normal rats. The levels of allograft inflammatory factor-1, peroxiredoxin I and actin-related protein 2/3 complex subunit 5 were significantly regulated by JJNR (P<0.01). These proteins were closely associated with immune response and cell movement. CONCLUSION: The results suggest that there are differential protein expressions between EAMG rats and normal rats. Furthermore, as a Chinese medicine prescription with effect of invigorating spleen and kidney, JJNR can effectively regulate the levels of some EAMG-related protein expression.

Objective To investigate the predictive value of multiple CT signs in the diagnosis of benign and malignant thyroid nodules.Methods The CT data of 1 009 nodules with diameter >1.0 cm confirmed by histology from 931 patients was retrospectively analyzed, including 548 benign nodules from 484 patients and 461 malignant nodules from 447 patients.According to the inspection time, all nodules were divided into model group(2009—2014)and test group(2015—2016).The distribution of nodules with irregular shape, bite cake syndrome, micro calcification, enhanced range reduction/blur, cystic and high enhancement were evaluated in two groups.Univariate and multivariate logistic regression analysis were performed to evaluate the predicting value of multiple CT sighs for benign and malignant thyroid nodules in two groups.Results The numbers of benign and malignant nodules were 252 and 233 in model group,and were 296 and 228 in test group.The univariate logistic analysis of the model group and the test group showed that irregular shape, bite cake syndrome, micro calcification, enhanced range reduction/blur were more common in malignant nodules.OR values were 4.172 and 6.327,3.927 and 3.493,5.354 and 6.674, 11.814 and 5.082,8.680 and 14.562,respectively.The areas under the predicted probability curve were 0.946 and 0.936, respectively.The micro calcification was an independent predictive factor in the multivariate logistic regression analysis in the model group but not in the test group.Conclusion Irregular shape,bite cake syndrome and enhanced blur/range reduction are the CT signs of the stable malignant nodules,cystic and high enhancement are the CT signs of stable and benign nodules.Combination of multiple CT signs could improve the accuracy of diagnosis for Benign and Malignant Thyroid Nodules.

Objective To investigate the diagnostic value of lymph node size and distribution in ipsilateral central lymph node metastasis (ICLNM) of single papillary thyroid carcinoma (PTC) in CT examination.Method The CT data of 278 single PTC with diameter ＞ 1.0 cm confirmed by operation and pathology were retrospectively analyzed.According to the ipsilateral central lymph node diameter,these cases were divided into ＜ 0.2 cm group,0.2-0.4 cm group and ≥0.4 cm group,and the distribution difference of ICLNM positive and negative between the three groups were analyzed.Then according to the lymph node distribution,0.2 to 0.4 cm group were divided into turbidity group (≥ 3) and non-turbidity group (1-2),and ≥0.4 cm group were divided into cluster group (≥ 3) and non-cluster group (1-2).The differences betweeen turbidity group and non-turbidity group,cluster group and non-cluster group were analyzed.Results In 278 PTC,the proportion of ICLNM positive and negative was 65.8％(183/278) and 34.2％(95/278),respectively.ICLNM positive in ＜0.2 cm group,0.2-0.4 cm group and ≥0.4 cm group accounted for 37.3％ (31/83),68％ (66/97) and 87.8％ (86/98),respectively.x2 value and P value in between groups and within groups were 51.082 and 0,16.956 and 0,49.955 and 0,11.022 and 0.001,respectively.ICLNM positive in turbidity group and non-turbidity group accounted for 74.0％ (57/77) and 45％ (9/20),respectively.x2 value and P value were 6.151 and 0.013,respectively.ICLNM positive in cluster group and and non-cluster group accounted for 92.6％(50/54) and 82％(36/44),respectively.x2 value and P value were 2.619 and 0.106,respectively.Conclusions Among CT examination of patients with PTC,with the increase of the diameter and number of lymph nodes in central group,the positive proportion of ICLNM positive increases.For the 0.2-0.4 cm group,the turbidity phenomenon suggests that the possibility of metastasis is greater.The accurate identification of these signs can help surgeons take a more thorough surgical treatment and have great significance to reduce postoperative recurrence.

Objective:To analyze the potential role and prognostic value of platelet-to-lymphocyte ratio (PLR) at an early stage in arterial-venous extracorporeal membrane oxygenation (VA -ECMO).Methods:Totally 83 adult patients with VA-ECMO from June 2018 to June 2020 treated at Emergency Department of Jiangsu Provincial Hospital were retrospectively analyzed. Baseline characteristics between survivors ( n=46) and non-survivors ( n=37) were compared. Logistic regression analysis was used to predict the risk factors associated with 28-day mortality in VA-ECMO patients. The cut-off value was calculated by the receiver operating characteristic (ROC) curve. Results:PLR48-h ( OR=1.018,95% CI: 1.001-1.036, P=0.039) and continuous renal replacement therapy (CRRT) ( OR=7.095,95% CI: 1.099-45.799, P=0.039) were relevant risk factors of 28-day mortality in VA-ECMO patients. The cut-off value of PLR48-h was 156.3 [sensitivity: 57.8%, specificity: 86.1%, and area under the curve (AUC): 0.756]. Compared with the high PLR group (>156.3), the incidences of acute kidney injury (AKI) ( P<0.001) and bleeding events ( P=0.013) were significantly higher in the low PLR group (<156.3). Conclusions:The early PLR reduction and CRRT application during VA-ECMO support are related to poor prognosis.

Objective:To investigate the clinical significance of the acute physiology and chronic health evaluationⅡ (APACHEⅡ) combined with different systematic inflammation markers (SIMs) including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR)-in adult patients with venous-arterial extracorporeal membrane oxygenation (VA-ECMO).Methods:A total of 89 adult patients with VA-ECMO ( ≥ 3 d) in the Emergency Department of Jiangsu Provincial People's Hospital from January 2017 to June 2020 were retrospectively analyzed. Patients were divided into two groups: survivors ( n=39) and non-survivors ( n=50). The baseline APACHE Ⅱscore and PLR, NLR, LMR before ECMO implantation and at 1, 2, 3 day after ECMO were recorded. Binary logistic regression was used to analyze the risk factors of 28-day mortality in patients with VA-ECMO. The utility of APACHEⅡ score and SIMs alone or combination for predicting clinical prognosis was evaluated using receiver operating characteristic (ROC) curve analysis. The patients were divided into the high risk group and the low risk group according to the best cut-off value, and the difference of ECMO-related complications between the two groups was compared. Results:When combined APACHEⅡ score with SIMs, APACHEⅡ + PLR 48 h + LMR 24 h + LMR 72 h demonstrated the greatest predictive ability with an AUC of 0.833. Compared with the high-risk group, the low-risk group has a lower incidence of acute renal injury, infection, bleeding complications, the use of continuous renal replacement therapy, mechanical ventilation, and a higher hospital survival rate.Conclusions:The combination of APACHEⅡ score and SIMs-PLR, LMR- is better than a single one for death prediction, and it is expected to be a new predictive model for early identification of the risk of death or poor prognosis in patients with VA-ECMO.

Objective:To explore the prognostic value of survival after veno-arterial ECMO (SAVE) score combined with 24-h lactate on the machine in patients with extracorporeal cardiopulmonary resuscitation (ECPR).Methods:Totally 59 patients treated with ECPR in the Emergency Department of the First Affiliated Hospital of Nanjing Medical University from April 2017 to June 2021 were retrospectively analyzed. According to the 28-day prognosis, the patients were divided into the death group ( n=36) and the survival group ( n=23). The differences in baseline data were analyzed, and multivariate logistic regression was performed to identify the influencing factors of 28-day mortality in patients with ECPR. The receiver operating characteristic (ROC) curve was applied to evaluate the predictive value of SAVE score, 24-h lactate and their combined detection for predicting 28-day mortality risk in patients with ECPR. Results:The 28-day survival rate of patients with ECPR was 39% (23/59). SAVE score of the death group was significantly lower than that of the survival group (-11.67±4.60 vs. -2.43±4.77, P<0.001), and the 24-h lactate in the death group was significantly higher than that in the survival group [5.94 (3.37, 12.40) mmol/L vs. 1.65 (1.07, 3.15) mmol/L, P<0.001]. Multivariate logistic regression analysis showed that SAVE score ( OR=0.703, 95% CI: 0.566-0.873, P=0.001) and 24-h lactate ( OR=1.608, 95% CI: 1.025-2.523, P=0.039) were independent influencing factors of 28-day mortality in ECPR patients. ROC curve analysis showed that the best cut-off value of SAVE score was -6, the sensitivity was 78.30% and specificity was 91.70%. The best cutoff value of 24-h lactate was 4.7 mmol/L, the sensitivity was 63.90% and specificity was 100.00%. The sensitivity and specificity of the combined detection of SAVE score and 24-h lactate were 82.60% and 100.00%, respectively. The area under the curve (AUC) of SAVE score combined with 24-h lactate for predicting the 28-day mortality risk in patients with ECPR was larger than that of SAVE score and 24-h lactate alone (0.952 vs. 0.917; 0.952 vs. 0.847). Conclusions:Lower SAVE score and higher 24-h lactate are independently risk factors of 28-day mortality in patients with ECPR, and SAVE score combined with 24-h lactate on the machine has a good predictive value for the prognosis of patients with ECPR.

Objective:To investigate the safety of early whole body computed tomography (WBCT) combined with coronary angiography (CAG) in patients with extracorporeal cardiopulmonary resuscitation (ECPR) and its application value in the diagnosis of cardiac arrest and complications of cardiopulmonary resuscitation (CPR).Methods:This was a retrospective study. Patients who underwent ECPR in the Emergency Department of the First Affiliated Hospital of Nanjing Medical University from January 2017 to July 2021 were enrolled in this research. Patients younger than 18 years or with incomplete clinical data were excluded. The results of WBCT and CAG examinations after ECPR were collected.Results:A total of 89 patients with ECPR, aged (47±17) years, were enrolled in the study, all underwent WBCT examination, and no adverse events such as ECMO and tracheal tube shedding occurred. WBCT found 7 cases of pulmonary embolism, 3 cases of aortic dissection and 2 cases of cerebral hemorrhage. WBCT identified CPR-related complications in 42 cases, including rib fractures ( n=20), pneumothorax ( n=5), mediastinal emphysema ( n=5), subcutaneous emphysema ( n=6), and hematoma or swelling at puncture site ( n=6). Fifty-five patients underwent CAG examination, the most common culprit vessels were the left anterior descending branch disease (58.2%) followed by the left circumflex branch disease (27.3%), the right coronary artery disease (21.8%) and left main artery disease (12.7%). Conclusions:Early WBCT and CAG examinations are of great significance and safety for the guidance of treatment in ECPR patients.

Objective:To observe the effects of early energy intake and early enteral nutrition on prognosis of patients during extracorporeal membrane oxygenation (ECMO).Methods:Patients who received ECMO treatment in the emergency intensive care unit (EICU) of the Jiangsu Provincial Hospital (First Affiliated Hospital of Nanjing Medical University) from January 2021 to June 2022 were selected as subjects to summarize the early energy intake of ECMO patients. Logistic regression analysis and restricted cubic spline (RCS) analysis were used to determine the relationship between early energy intake and prognosis of ECMO patients. According to the results of RCS analysis, the patients were divided into energy-deficient group and energy-sufficient group. And according to whether early enteral nutrition (EEN) was initiated, the patients were divided into EEN group and non-EEN group. The differences of clinical outcomes between energy-deficient group and energy-sufficient group, EEN group and non-EEN group were compared.Results:There was no significant difference in age, sex, BMI, primary disease and ECMO pattern between energy-deficient group and energy-sufficient group, EEN group and non-EEN group. The ECMO conversion time (days) and hospitalization time (days) in the energy-deficient group were significantly lower than those in the energy-sufficient group, and the survival rate in the energy-deficient group was significantly lower than that in the energy-sufficient group [43.2% (19/44) vs. 66.0% (31/47), P=0.029]. Kaplan-Meier survival analysis showed that the 28-day survival rate in the energy-deficient group was significantly lower than that in the energy-sufficient group, and the risk of death was 2.595 times higher than that in the energy-sufficient group. The conversion time (days), hospital stay (days) and average daily energy intake [kcal/(kg·d)] in the EEN group were higher than those in the non-EEN group ( P<0.05), and the survival rate in the non-EEN group was significantly higher than that in the non-EEN group [66.1% (41/62) vs. 31.0% (9/29), P<0.002]. Kaplan-Meier survival analysis showed that the 28-day survival rate in the non-EEN group was significantly lower than that in the EEN group, and the risk of death was 2.981 times higher than that in the EEN group ( P<0.001). Conclusions:The energy intake of patients with ECMO above 16.94 kcal/ (kg·d) is a protective factor for prognosis. EEN helps to increase early energy intake and improve prognosis in patients during ECMO.
