Abstract
Objective: To investigate the biological behavior spectrum of platelet-derived growth factor alpha receptor (PDGFRA)-mutant gastrointestinal stromal tumor (GIST), and to compare the clinical values of the Zhongshan method of benign and malignant evaluation with the modified National Institutes of Health (NIH) risk stratification. Methods: A total of 119 cases of GIST with PDGFRA mutation who underwent surgical resection at Zhongshan Hospital, Fudan University from 2009 to 2020 were collected. The clinicopathological data, follow-up records, and subsequent treatment were reviewed and analyzed statistically. Results: There were 79 males and 40 females. The patients ranged in age from 25 to 80 years, with a median age of 60 years. Among them, 115 patients were followed up for 1-154 months, and 13 patients progressed to disease. The 5-year disease-free survival (DFS) and overall survival (OS) were 90.1% and 94.1%, respectively. According to the modified NIH risk stratification, 8 cases, 32 cases, 38 cases, and 35 cases were very-low risk, low risk, intermediate risk, and high risk, and 5-year DFS were 100.0%, 95.6%, 94.3%, and 80.5%, respectively. There was no significant difference in prognosis among the non-high risk groups, only the difference between high risk and non-high risk groups was significant (P=0.029). However, the 5-year OS was 100.0%, 100.0%, 95.0% and 89.0%, and there was no difference (P=0.221). According to the benign and malignant evaluation Zhongshan method, 43 cases were non-malignant (37.4%), 56 cases were low-grade malignant (48.7%), 9 cases were moderately malignant (7.8%), and 7 cases were highly malignant (6.1%). The 5-year DFS were 100.0%, 91.7%, 77.8%, 38.1%, and the difference was significant (P<0.001). The 5-year OS were 100.0%, 97.5%, 77.8%, 66.7%, the difference was significant (P<0.001). Conclusions: GIST with PDGFRA gene mutation shows a broad range of biological behavior, ranging from benign to highly malignant. According to the Zhongshan method, non-malignant and low-grade malignant tumors are common, the prognosis after surgery is good, while the fewer medium-high malignant tumors showed poor prognosis after surgical resection. The overall biological behavior of this type of GIST is relatively inert, which is due to the low proportion of medium-high malignant GIST. The modified NIH risk stratification may not be effective in risk stratification for PDGFRA mutant GIST.

Abstract
Objective: To explore the value of the aMAP risk score (age, male, albumin-bilirubin, and platelets) to predict early recurrence within one year after microwave ablation in patients with small hepatocellular carcinoma. Methods: This was a retrospective study that enrolled 142 patients diagnosed with hepatocellular carcinoma who were treated with microwave ablation in the Department of Hepatology Unit of Nanfang Hospital, Southern Medical University from July 2016 to July 2021. The cohort enrolled 121 male and 21 female patients, including 110 patients that were <60 years old. All the patients were followed-up after microwave ablation to evaluate residual tumor and recurrence of tumor by computed tomography or magnetic resonance imaging. The observation indices mainly included general data and imaging data of patients. Using the X-tile tools, patients were divided into two groups: a high aMAP score group and a low aMAP score group. Multivariate Cox regression analysis was conducted for comparison of independent risk factors. Results: Multivariate Cox regression showed that high aMAP score, maximum tumor diameter >20 mm, and high AFP were the independent risk factors of early recurrence (all P<0.05). Kaplan-Meier survival curves showed that the median recurrence-free survival was 25.5 months in the low aMAP score group and 6.1 months in the high aMAP score group (P=0.001). Conclusions: The aMAP score could predict the early recurrence within 1 year of small hepatocellular carcinoma after microwave ablation. Patients with high aMAP score should undergo rigorous postoperative follow-up evaluations..

Abstract
Objective: To investigate the influence of hemoglobin glycation index (HGI) on the risk of incident chronic kidney disease (CDK) among nondiabetic patients. Methods: Prospective cohort study. At baseline, a total of 7 407 nondiabetic patients without a history of CKD from Pingguoyuan Community of the Shijingshan District in Beijing were included from December 2011 to August 2012, who were then divided into three groups according to the tertiles of their baseline HGI levels. The CKD incidence rate was compared among the different HGI groups at last follow-up. Cox multivariable regression was applied to evaluate whether HGI measures predicted CKD risk. Test for trend across tertiles were examined using ordinal values in separate models. Results: The mean age of the subjects was (56.4±7.5) years, and 4 933 (66.6%) were female. At mean follow-up of 3.23 years, 107 (1.4%) individuals developed CKD. The incidence of CKD was gradually increasing from the low to high HGI groups [1.1% (28/2 473) vs. 1.2% (31/2 564) vs. 2.0% (48/2 370), P=0.016]. In the multivariate Cox regression analysis, after adjustment for potential confounders, the high HGI group had a 68.5% increased risk of CKD compared with the low HGI group (HR=1.685, 95%CI 1.023 to 2.774). CKD risk increased with increasing HGI tertiles (P for trend=0.028). Conclusion: High HGI is associated with an increased risk for CKD in the nondiabetic population, indicating that HGI may help identify individuals at high risk for CKD.

Abstract
BACKGROUND Hyperlipidemia is a common complication after liver transplantation (LT) and develops mostly in the early posttransplant period. Recently, some studies have reported a positive correlation between hyperlipidemia and favorable prognosis in patients with hepatocellular carcinoma (HCC) undergoing hepatectomy. This study aimed to evaluate the possibility of predicting prognosis in HCC patients receiving LT by early posttransplant dyslipidemia. METHODS From January 2015 to December 2017, a total of 806 HCC patients from China Liver Transplant Registry database were retrospectively enrolled. The prognostic relevance of early posttransplant hypertriglyceridemia or hypercholesterolemia was examined using survival analysis, and subgroup analysis was implemented based on LT criteria. RESULTS Early posttransplant hypercholesterolemia (EPHC) was independently inversely associated with the risk of recurrence [hazard ratio (HR) = 0.630; P = 0.022], but was not significantly correlated with the mortality. However, early posttransplant hypertriglyceridemia was not related to prognosis. Intriguingly, with further classification, we found that borderline EPHC (B-EPHC), instead of significant EPHC, was a predictor of lower risk for both recurrence (HR = 0.504; P = 0.006) and mortality (HR = 0.511; P = 0.023). Compared with non-EPHC patients, B-EPHC patients achieved significantly superior 1-year and 3-year tumor-free survival (89.6% and 83.7% vs. 83.8% and 72.7% respectively; P = 0.023), and 1-year and 3-year overall survival (95.8% and 84.8% vs. 94.6% and 77.6% respectively; P = 0.039). In the subgroup analysis, B-EPHC remained an independent predictor of better prognosis in patients beyond Milan criteria and those within Hangzhou criteria; whereas there was no significant relationship between B-EPHC and prognosis in patients within Milan criteria and those beyond Hangzhou criteria. More interestingly, patients beyond Milan criteria but within Hangzhou criteria were identified as the crucial subpopulation who benefited from B-EPHC (recurrence HR = 0.306, P = 0.011; mortality HR = 0.325, P = 0.031). CONCLUSIONS B-EPHC could assist transplant teams in dynamically evaluating prognosis after LT for HCC as a postoperative non-oncological biomarker, especially in patients beyond Milan criteria but within Hangzhou criteria.

Abstract
Objective: To investigate the prognostic factors of children with congenital heart disease (CHD) who had undergone cardiopulmonary resuscitation (CPR) in pediatric intensive care unit (PICU) in China. Methods: From November 2017 to October 2018, this retrospective multi-center study was conducted in 11 hospitals in China. It contained data from 281 cases who had undergone CPR and all of the subjects were divided into CHD group and non-CHD group. The general condition, duration of CPR, epinephrine doses during resuscitation, recovery of spontaneous circulation (ROSC), discharge survival rate and pediatric cerebral performance category in viable children at discharge were compared. According to whether malignant arrhythmia is the direct cause of cardiopulmonary arrest or not, children in CHD and non-CHD groups were divided into 2 subgroups: arrhythmia and non-arrhythmia, and the ROSC and survival rate to discharge were compared. Data in both groups were analyzed by t-test, chi-square analysis or ANOVA, and logistic regression were used to analyze the prognostic factors for ROSC and survival to discharge after cardiac arrest (CA). Results: The incidence of CA in PICU was 3.2% (372/11 588), and the implementation rate of CPR was 75.5% (281/372). There were 144 males and 137 females with median age of 32.8 (5.6, 42.7) months in all 281 CPA cases who received CPR. CHD group had 56 cases while non-CHD had 225 cases, with the percentage of 19.9% (56/281) and 80.1% (225/281) respectively. The proportion of female in CHD group was 60.7% (34/56) which was higher than that in non-CHD group (45.8%, 103/225) (χ2=4.00, P=0.045). There were no differences in ROSC and rate of survival to discharge between the two groups (P>0.05). The ROSC rate of children with arthythmid in CHD group was 70.0% (28/40), higher than 6/16 for non-arrhythmic children (χ2=5.06, P=0.024). At discharge, the pediatric cerebral performance category scores (1-3 scores) of CHD and non-CHD child were 50.9% (26/51) and 44.9% (92/205) respectively. Logistic regression analysis indicated that the independent prognostic factors of ROSC and survival to discharge in children with CHD were CPR duration (odds ratio (OR)=0.95, 0.97; 95%CI: 0.92~0.97, 0.95~0.99; both P<0.05) and epinephrine dosage (OR=0.87 and 0.79, 95%CI: 0.76-1.00 and 0.69-0.89, respectively; both P<0.05). Conclusions: There is no difference between CHD and non-CHD children in ROSC and survival rate of survival to discharge was low. The epinephrine dosage and the duration of CPR are related to the ROSC and survival to discharge of children with CHD.

Abstract
BACKGROUND Acute kidney injury (AKI) is a common complication after liver transplantation (LT) and is an indicator of poor prognosis. The establishment of a more accurate preoperative prediction model of AKI could help to improve the prognosis of LT. Machine learning algorithms provide a potentially effective approach. METHODS A total of 493 patients with donation after cardiac death LT (DCDLT) were enrolled. AKI was defined according to the clinical practice guidelines of kidney disease: improving global outcomes (KDIGO). The clinical data of patients with AKI (AKI group) and without AKI (non-AKI group) were compared. With logistic regression analysis as a conventional model, four predictive machine learning models were developed using the following algorithms: random forest, support vector machine, classical decision tree, and conditional inference tree. The predictive power of these models was then evaluated using the area under the receiver operating characteristic curve (AUC). RESULTS The incidence of AKI was 35.7% (176/493) during the follow-up period. Compared with the non-AKI group, the AKI group showed a remarkably lower survival rate (P < 0.001). The random forest model demonstrated the highest prediction accuracy of 0.79 with AUC of 0.850 [95% confidence interval (CI): 0.794-0.905], which was significantly higher than the AUCs of the other machine learning algorithms and logistic regression models (P < 0.001). CONCLUSIONS The random forest model based on machine learning algorithms for predicting AKI occurring after DCDLT demonstrated stronger predictive power than other models in our study. This suggests that machine learning methods may provide feasible tools for forecasting AKI after DCDLT.

Abstract
Objective: To examine the perioperative safety and feasibility of simultaneous off-pump coronary artery bypass grafting (OPCAB) with non-cardiac surgical procedures of moderate-to-severe severity. Methods: The perioperative results of 54 patients underwent simultaneous OPCAB with non-cardiac surgical procedures from September 2013 to January 2019 at Department of Cardiac Surgery, Peking University First Hospital were assessed retrospectively. There were 46 males and 8 females, aging (65.8±8.8) years (range: 41 to 85 years). All simultaneous non-cardiac surgical procedures, including vascular (n=1), thoracic (n=26), general (n=12) and urologic surgical procedures (n=15), were assessed to be of moderate-to-severe grade by operative severity scoring system. Perioperative results were compared between the OPCAB patients who underwent simultaneous non-cardiac surgical procedures (n=54) and 1∶2 matched patients who underwent isolated OPCAB performed most recently by the same cardiac team with similar procedures accordingly (n=108), using t test, Mann-Whitney U test, χ2 test or Fisher exact test. Results: All baseline factors were matched between the two groups, with no significant difference on European system for cardiac operative risk evaluation (EuroSCORE) Ⅱ (1.185(0.758)% vs. 1.215(0.905)%, Z=‒0.036, P=0.972). No perioperative death was observed in the two groups. Although patients underwent simultaneous non-cardiac surgical procedures showed prolonged operation duration time ((324.9±97.1) minutes vs. (166.7±36.7) minites, t=11.564, P<0.01) and increased intraoperaive blood loss ((462.2±269.6) ml vs. (304.5±177.8) ml, t=3.866, P<0.01), primary postoperative complications, including perioperative myocardial infarction, atrial fibrillation, perioperative stroke, acute renal failure, wound infection, and bleeding reoperation did not show significant differences between the two groups (all P>0.05), while total blood transfusion volume, mechanical ventilation time and intensive care unit residence time also showed no significant differences between the two groups (all P>0.05). Conclusion: Simultaneous OPCAB with non-cardiac surgical procedures of moderate-to-severe severity in patients with operative indications are safe and feasible, and are not associated with increased postoperative risks when compared with isolated OPCAB.

Abstract
Objective: To evaluate the postoperatively hidden blood loss of elderly intertrochanteric fracture patients fixed with combined external fixator, and to explore the correlation between hidden blood loss and age. Methods: A retrospective analysis was conducted on 60 elderly intertrochanteric fracture patients who were admitted to the Department of Orthopedics of Hebei Provincial Hospital from January 2016 to May 2019. All the fractures were fixed with combined external fixators. The patients were divided into two groups according to the age: there were 31 cases in group A (60-80 years old) and 29 cases in group B (≥80 years old). The Gross equation and the Nandler formula were used to evaluate the amount of hidden blood loss based on changes in hematocrit (Hct) at the day preoperatively, 3 days postoperatively and the weight. The data were compared between the two groups by independent-sample t test. Results: The decreased Hct, hemoglobin(Hb) and the dominant blood loss and hidden blood loss in group A and B was 3.4%±1.7%, (13±7) g/L, (25±6) ml, (186±7) ml and 3.8%±1.2%, (13±3) g/L, (24±8) ml, (194±7) ml, respectively. There was no significant differences in the dominant and hidden blood loss between the groups (t=0.309, 0.883, both P>0.05). Conclusion: The age doesn't affect the hidden blood loss in elderly intertrochanteric fracture patients fixed with combined external fixator, which indicated that the operation is safe and reliable for such patients.

Abstract
The purpose of this study was to compare the complications of patients treated for a benign parotid tumour (BPT) by extracapsular dissection (ECD) vs. partial superficial parotidectomy (PSP). A comprehensive literature investigation was conducted by searching electronic databases. A systematic review and meta-analysis of comparative studies were performed to assess ECD and PSP for the treatment of BPTs with fixed-effects models. The outcomes analysed were transient or permanent facial nerve injury, Frey syndrome, recurrence rate, infection, and salivary fistula/sialocele. A total of 1641 patients from seven studies (1120 ECD-treated and 521 PSP-treated patients) were included in this meta-analysis. Transient facial nerve injury (odds ratio (OR)=0.28, 95% confidence interval (CI): 0.11-0.71; p=0.008) and Frey syndrome (OR=0.12, 95% CI: 0.03-0.48; p=0.003) were less prevalent in the ECD group. The rates of permanent facial nerve injury (OR=0.77, 95% CI: 0.35-1.70; p=0.520), recurrence rate (OR=0.17, 95% CI: 0.02-1.75; p=0.14), infection (OR=0.70, 95% CI: 0.07-6.67; p=0.76), and salivary fistula/sialocele (OR=0.40, 95% CI: 0.06-2.66; p=0.350) were similar in both groups. Although there was a trend that ECD showed a reduced risk for complications, the present results are not sufficient to conclude that ECD is more beneficial than PSP.

Abstract
BACKGROUND New-onset hyperglycemia (NOH) is a common phenomenon after liver transplantation (LT), but its impact on clinical outcomes has not yet been fully assessed. We aimed to evaluate the etiology and prognosis of NOH within 1 month after LT. METHODS The data of 3339 adult patients who underwent primary LT from donation after citizen death between January 2010 and June 2016 were extracted from China Liver Transplant Registry database and analyzed. NOH was defined as fasting blood glucose ≥7.0 mmol/L confirmed on at least two occasions within the first post-transplant month with or without hypoglycemic agent. RESULTS Of 3339 liver recipients, 1416 (42.4%) developed NOH. Recipients with NOH had higher incidence of post-transplant complications such as graft and kidney failure, infection, biliary stricture, cholangitis, and tumor recurrence in a glucose concentration-dependent manner as compared to non-NOH recipients (P < 0.05). The independent risk factors of NOH were donor warm ischemic time >10 min, cold ischemic time >10 h, anhepatic time >60 min, recipient model for end-stage liver disease score >30, moderate ascites and corticosteroid usage (P < 0.05). Liver enzymes (alanine aminotransferase and gamma-glutamyltranspeptidase) on post-transplant day 7 significantly correlated with NOH (P < 0.001). CONCLUSIONS NOH leads to increased morbidity and mortality in liver recipients. Close surveillance and tight control of blood glucose are desiderated immediately following LT particularly in those with delayed graft function and receiving corticosteroid. Strategic targeting graft ischemic injury may help maintain glucose homeostasis.

Abstract
In this work, we studied the phase transitions and exchange bias of Ni50−xMn36Sn14Tx (T = Pd, Pt; x = 0, 1, 2, 3) alloys. An intermartensitic transition (IMT), not observed in Ni50Mn36Sn14 alloy, was induced by the proper application of negative chemical pressure by Pd(Pt) doping in Ni50−xMn36Sn14Tx (T = Pd, Pt) alloys. IMT weakened and was suppressed with the increase of applied field; it also disappeared with further increase of Pd(Pt) content (x = 3 for Pd and x = 2 for Pt). Another striking result is that exchange bias effect, ascribed to the percolating ferromagnetic domains coexisting with spin glass phase, is notably enhanced by nonmagnetic Pd(Pt) addition. The increase of unidirectional anisotropy by the addition of Pd(Pt) impurities with strong spin-orbit coupling was explained by Dzyaloshinsky-Moriya interactions in spin glass phase.

Abstract
Cadmium (Cd) is a well-known environmental carcinogen and immunotoxin. Currently the direct cytotoxic effects of Cd on thymocytes are largely unexplored. The main objective of the present study was to investigate the apoptogenic property of Cd and the mechanisms involved, using primary cultured mouse thymocytes as a model. Cd-induced apoptosis in thymocytes was studied by TdT-mediated dUTP nick end-labeling assay and DNA gel electrophoresis. The results showed that Cd was able to cause apoptosis in mouse thymocytes in a time- and dose-dependent manner. Moreover, Cd exposure led to a rapid and sustained intracellular calcium (Ca2+) elevation, followed by caspase-3 activation and PARP cleavage, all of which preceded the characteristic DNA fragmentation. BAPTA-AM, a specific intracellular Ca2+ chelator, abolished Cd-induced Ca2+ overloading and subsequently inhibited caspase-3 activation, PARP cleavage, and apoptosis. It is believed that intracellular Ca2+ elevation may trigger caspase-3 activation either through mitochondria or through activation of Ca2+-dependent protease in Cd-treated thymocytes. Results from this study thus provide new information for a better understanding of the immunotoxic and immunomodulatory effects of Cd.

Abstract
On tourniquet shock (ToS) rat model, it was found that the reactivity of isolated perfused aortic ring to noradrenaline was decreased, while the cGMP content of the aortic tissue was increased. These ToS-induced changes could be potentiated or attenuated respectively by perfusion with NO-precursor, L-arginine, or NO-synthesis inhibitor L-NNA independent of the presence of vascular endothelium. Guanylate cyclase inhibitor, methylene blue, could also attenuate the aortic reactivity. All these results suggest that the aortic musculature can produce a NO-LRF factor capable of lowering the vascular reactivity of the ToS animals. That L-arginine can ameliorate while L-NNA can exacerbate ToS, suggest that NO-LRF do play an adaptive role in the protective mechanism of the organism during ToS.

Abstract
Endothelin is a bioactive polypeptide released from vascular endothelium, which has a strong action promoting vascular contraction, proliferation and hypertrophy of vascular smooth muscle cells. The present investigation was performed on the hypertensive rat produced by narrowing abdominal aorta and drinking saline. It was observed that the level of plasma endothelin in the hypertensive rats was doubled (9.70 +/- 0.68 vs. sham group 4.11 +/- 0.33 pg/ml, P < 0.01), and administration of specific endothelin-antiserum into hypertensive rats significantly attenuated the increase in the blood pressure (18.97 + 1.32 vs. 27.33 + 0.09 kPa in untreated hypertensive rats, P < 0.01), and dramatically ameliorated malfunction resulting from myocardial hypertrophy. The results suggest that endothelin is an important factor in the pathogenesis of hypertension, and that inhibition of endothelin action may be a new effective way in prevention and therapy of hypertension.

Abstract
From 1949 through 1978, 31 patients with renal metastasis were diagnosed in a total of 448 cases of choriocarcinoma admitted to our hospital, giving an incidence of 6.9%. Renal metastasis was invariably preceded by pulmonary metastases and usually accompanied by other visceral metastases, indicating that renal metastasis is the result of dissemination of tumor cells secondarily from lung metastasis through the general circulation and should be categorized as arterial metastasis. Pyelogram is useful in the presence of medullary invasion by the tumor. Renal metastatic tumors are very sensitive to chemotherapy. Good response to chemical agents may be due to high drug concentration attained in the kidney tissue during excretion. Since successful treatment of renal metastasis by chemotherapy alone may be obtained, patients can be spared a major operation without jeopardizing the prognosis.

Abstract
From 1963 through 1988, a total of 194 hysterographies were performed for 111 patients. Three types of abnormalities were observed on the hysterogram: filling defect, intramural invasion of the uterine wall by the contrast medium; and intravasation of the contrast medium into the pelvic veins. The pathology and clinical significance of three types of abnormalities were studied. The results showed that hysterography demonstrated better images than pelvic arteriography and B-scan for the diagnosis of choriocarcinoma and invasive mole, especially when combined with B-scan/or pelvic arteriography, a greater accuracy was achieved.

Abstract
In order to preserve the fertility of young patients with choriocarcinoma and invasive mole, chemotherapy alone was given without hysterectomy in 265 cases from 1959 through 1980. By the end of 1985, 205 patients had become pregnant after recovery, with a total of 355 pregnancies. Among these, 23 were terminated by induced abortions, 26 as miscarriages, two as ectopic gestations, two as intrauterine deaths, and three as stillbirths. Among 303 livebirths (including four sets of twins), six infants died neonatally, three of whom were found to have congenital anomalies incompatible with life, and two died during infancy. All the remaining 295 children had normal growth and development, the oldest now being 25 years of age. The rates of fetal wastage, malformations, twin pregnancies, and neonatal and infantile deaths did not deviate from the normal. Cytogenetic study of the peripheral lymphocytes of 94 of the children revealed no increase of chromosomal aberrations. The rates of recurrence of disease and of death caused by recurrence of disease in these were not increased in comparison with those in patients who underwent hysterectomy. These data indicate that treatment of malignant trophoblastic neoplasms with chemotherapy alone is compatible with the preservation of fertility in most women.
