Objective To investigate the effect of ultrasound-guided stellate ganglion block(SGB)on intraoperative fentanyl dosage in the patients undergoing open thyroidectomy.Methods A total of 70 patients with elective open thyroidectomy under general anesthesia in the Affiliated Hospital of North Sichuan Medical College from November 2021 to April 2022 were selected as the study subjects and divided into the SGB group(group S,n=35)and the control group(group C,n=33).The group S conducted ultrasound-guided SGB at 15 min before anesthetic induction(injection of 0.25％marcaine 6-8 mL),and group C conducted the stellate ganglion recognition under the ultrasound guidance in 15 min before anesthetic induction without conducting other operations.All patients all received the anesthesia induction and maintenance under the same BIS moni-toring.The fentanyl dosage,recovery time,anesthetic drugs dosage,fluid infusion amounts,bleeding volume,use rate of atropine and ephedrine,operation time and postoperative complications as well as the VAS scores in PACU 30 min,at postoperative 3,6,12,24 h were recorded.Results Compared with group C,the intraopera-tive amount of fentanyl in group S was significantly decreased[(247.9±65.4)μg vs.(295.7±61.5)μg,P=0.003].The propofol dosage,cisatracurium dosage,fluid infusion amounts,bleeding amounts,use rate of atro-pine and ephedrine,recovery time and incidence rate of complications had no statistical differences between the two groups(P＞0.05).The VAS scores at various time points in group S all were lower than those in group C(P＜0.05).Conclusion Ultrasound-guided SGB could reduce the fentanyl use amounts during operation in the patients with open thyroidectomy.

Objective:To explore the value of baseline PET/CT parameters for predicting prognosis in patients with double-expression lymphoma (DEL).Methods:The clinical and 18F-FDG PET/CT data of 118 patients (66 males, 52 females; age: 28-85 years) with diffuse large B-cell lymphoma (DLBCL) diagnosed in Nanjing Drum Tower Hospital, Affiliated Hospital of Medical School, Nanjing University and the First Affiliated Hospital of Nanjing Medical University from June 2015 to September 2022 were retrospectively analyzed. The optimal thresholds for SUV max, total metabolic tumor volume (TMTV) and total lesion glycolysis (TLG) in predicting overall survival (OS) rate were determined using ROC curve analysis. Univariate and multivariate analyses, along with Kaplan-Meier survival analysis were performed to construct a survival prediction model. The effect of the model was evaluated by the calibration curve for the model, the time-dependent ROC curve analysis and decision curve analysis. Results:As of the last follow-up, 25 patients died, and the OS rate was 78.8%(93/118). The AUC of the ROC curve for TMTV was 0.705, with a corresponding optimal threshold of 230.9 cm 3. In multivariate analysis, Eastern Cooperative Oncology Group performance status (ECOG PS) score (hazard ratio ( HR)=3.886, 95% CI: 1.455-10.375; P=0.007) and TMTV ( HR=4.649, 95% CI: 1.665-12.979; P=0.003) were identified as independent predictors of OS. The combined model of ECOG PS score and TMTV was superior to ECOG PS score model and TMTV model alone in predicting OS. Conclusion:TMTV, a metabolic indicator, and ECOG PS score, a clinical risk factor, are independent predictors of OS in patients with DEL, and their combination can provide more accurate prognostic predictions.

Objective:To study the survival and prognostic factors for the recurrent extracranial malignant germ cell tumors (MGCTs) in children, and to explore feasible salvage treatment.Methods:A retrospective study.Pediatric patients with recurrent extracranial MGCTs diagnosed in Shanghai Children′s Medical Center between January 2010 and January 2020 were retrospectively recruited.Comprehensive treatment regimens included surgery, chemotherapy and radiation.Kaplan-Meier survival analysis and Cox regression model were employed to analyze the survival and prognostic factors for children with recurrent extracranial MGCTs.Results:A total of 172 children with extracranial MGCTs were treated, including 21 (12.2%) recurrent cases.The median time of MGCT recurrence after the end of the first treatment was 11 months.Finally, 19 patients were recruited after excluding 2 non-eligible cases, including 10 boys and 9 girls with the age at recurrence of 26 (8-170) months.The follow-up time was 57 (13-122) months.Salvage chemotherapy, complete resection and radiotherapy were performed in 16, 14 and 4 patients, respectively.The 4-year overall survival (4yr-OS) rate was (82.5±9.2)%(19 cases). The 4yr-OS rate was significantly higher in patients managed with surgery but without adjuvant chemotherapy at the initial treatment (13 cases) than those managed with chemotherapy at the initial treatment (6 cases)[(92.3±7.4)% vs.(60.0%±21.9)%, P=0.002]. Univariant and Cox multivariant regression analyses showed that failure to achieve the normal range of alpha fetoprotein after 3 cycles of chemotherapy significantly influenced the survival of recurrent extracranial MGCTs. Conclusions:For patients with recurrent extracranial MGCTs, comprehensive treatment approaches like complete surgical resection, chemotherapy, and radiotherapy offer a favorable survival rate.Specifically, recurrent and re-treated patients who initially received surgery alone without adjuvant chemotherapy have a higher survival rate compared to those who received chemotherapy during the initial treatment.

Objective:To explore the prognostic value of 18F-FDG PET-based radiomics features by machine learning in older patients(≥60 years) with diffuse large B-cell lymphoma (DLBCL). Methods:A total of 166 older patients (88 males, 78 females, age: 60-93 years) with DLBCL who underwent pre-therapy 18F-FDG PET/CT from March 2011 to November 2019 were enrolled in the retrospective study. There were 115 patients in training cohort and 51 patients in validation cohort. The lesions in PET images were manually drawn and the obtained radiomics features from patients in training cohort were selected by the least absolute shrinkage and selection operator (LASSO), random forest (RF), and extreme gradient boosting (Xgboost), and then classified by support vector machine (SVM) to build radiomics signatures (RS) for predicting overall survival (OS). A multi-parameter model was constructed by using Cox proportional hazard model and assessed by concordance index (C-index). Results:A total of 1 421 PET radiomics features were extracted and 10 features were selected to build RS. The univariate Cox regression analysis showed that RS was a predictor of OS (hazard ratio ( HR)=5.685, 95% CI: 2.955-10.939; P<0.001). The multi-parameter model that incorporated RS, metabolic metrics, and clinical risk factors, exhibited significant prognostic superiority over the clinical model, PET-based model, and the National Comprehensive Cancer Network International Prognostic Index (NCCN-IPI) in terms of OS (training cohort: C-index: 0.752 vs 0.737 vs 0.739 vs 0.688; validation cohort: C-index: 0.845 vs 0.798 vs 0.844 vs 0.775). Conclusions:RS can be used as a survival predictor for older patients(≥60 years) with DLBCL. Furthermore, the multi-parameter model incorporating RS is able to successfully predict prognosis.

Venous thromboembolism (VTE) is a complication in children with acute lymphoblastic leukemia (ALL). The Chinese Children's Cancer Group-ALL-2015 protocol was carried out in China, and epidemiology, clinical characteristics, and risk factors associated with VTE were analyzed. We collected data on VTE in a multi-institutional clinical study of 7640 patients with ALL diagnosed in 20 hospitals from January 2015 to December 2019. First, VTE occurred in 159 (2.08%) patients, including 90 (56.6%) during induction therapy and 108 (67.92%) in the upper extremities. T-ALL had a 1.74-fold increased risk of VTE (95% CI 1.08-2.8, P = 0.022). Septicemia, as an adverse event of ALL treatment, can significantly promote the occurrence of VTE (P < 0.001). Catheter-related thrombosis (CRT) accounted for 75.47% (n = 120); and, symptomatic VTE, 58.49% (n = 93), which was more common in patients aged 12-18 years (P = 0.023), non-CRT patients (P < 0.001), or patients with cerebral thrombosis (P < 0.001). Of the patients with VTE treated with anticoagulation therapy (n = 147), 4.08% (n = 6) had bleeding. The VTE recurrence rate was 5.03% (n = 8). Patients with VTE treated by non-ultrasound-guided venous cannulation (P = 0.02), with residual thrombus (P = 0.006), or with short anticoagulation period (P = 0.026) had high recurrence rates. Thus, preventing repeated venous puncture and appropriately prolonged anticoagulation time can reduce the risk of VTE recurrence.

Objective:To investigate the clinical, genetic, and clonality related aspects of individuals with Richter transformation (RT) .Methods:From January 2019 to December 2021, 18 RT patients with diagnoses at the First Affiliated Hospital of Nanjing Medical University (Pukou CLL center) were retrospectively examined. The immunoglobin heavy variable (IGHV) gene usage and IGHV-D-J rearrangement pattern of diagnosed CLL/SLL and transformed diffuse large B-cell lymphoma (DLBCL) were compared to determine the clonality relatedness. To investigate the risk factors of RT, Clinical and laboratory data from patients with newly diagnosed CLL/SLL and transformed DLBCL were gathered.Results:The median age of RT was 56.5 (41-75) years old. 17 patients transformed to DLBCL and 1 transformed to Hodgkin lymphoma (HL) . Of 17 individuals who had DLBCL transformation, 15 had CLL/SLL-related clonality and 2 had unrelated clonality. Next-generation sequencing (NGS) analysis of 11 paired initially diagnosed treatment-naive CLL/SLL and RT DLBCL found that EGR2、TP53 and NOTCH1 were among the most frequently mutated genes both in treatment-naive CLL/SLL and in RT DLBCL. In several cases, specific mutations were gained or lost throughout RT, indicating clonal evolution. Among 10 patients before exposure to BTK inhibitors before RT, four patients acquired BTK mutation. The aforementioned mutations should be considered high-risk variables for transformation; in addition, TP53 and EGR2 mutations could be linked to a poor prognosis following RT in patients receiving a cocktail of new medicines.Conclusion:Most RT DLBCL patients in our center are clonality related (15/17, 88.2% ) and we recommend all qualified centers to evaluate clonality relatedness of RT DLBCL patients. There was some variability in the mutational landscape between DLBCL that had undergone a transformation and initially diagnosed, treatment-naive CLL/SLL. The underlying molecular mechanism of RT needs more research.

Objective:To summarize the effect of Chinese Children′s Cancer Group (CCCG) Wilms tumor (WT)-2015 protocol.Methods:This was a prospective study. CCCG-WT-2015 protocol was revised on the basis of the CCCG-WT-2009 protocol. Clinical data of 288 children diagnosed with newly diagnosed kidney neoplasms in fourteen pediatric centers between September 2015 to December 2018 were summarized. The age of onset, distribution of pathological subtypes, staging, curative effect and prognostic factors of these children were analyzed. Kaplan-Meier method was used for survival curve and Log-Rank method was used for univariate analysis.Results:Among 288 cases with kidney neoplasms, there were 261 cases of WT, including 254 cases (97.3%) with favorable histology (FH) WT and 7 cases (2.7%) with unfavorable histology WT (UFHWT). The 3 year events free survival (EFS) rate for FHWT and UFHWT were (88.9±2.1)% and (80.0±17.9)%, which were better than that in WT-2009 (81.2% and 71.7%). In the 96 cases of stage Ⅲ/Ⅳ FHWT with indications for radiotherapy, 76 cases received radiation, another 20 cases received M protocol chemotherapy (cyclophosphamide, etoposide, gentamycin, vincristine and adriamycin) instead of radiation. The 3 year EFS rate for these two groups were (84.7±4.3)% and (84.7±8.1)%(χ 2=0.015, P=0.902). There were 22 renal clear cell sarcoma and 5 malignant rhabdoid tumor, 3 year EFS rate of them was (94.4±5.4)% and (20.0±17.9)%. Univariate analysis was performed for age, gender, pathological type, stage, whether rupture occurred during operation, whether complete remission (CR) occurred at the end of treatment and radiotherapy. Pathological types (χ 2=44.329, P<0.01) and failure to achieve CR at the end of the treatment (χ 2=49.459, P<0.01) were independent factor for predicting survival. Conclusion:Compared with CCCG-WT-2009, treatment of renal tumors in CCCG-WT-2015 study yielded good survival outcome, which can be further applied.

The clinical application of doxorubicin (DOX) in cancer chemotherapy is limited by its life-threatening cardiotoxic effects. Chrysophanol (CHR), an anthraquinone compound isolated from the rhizome of L., is considered to play a broad role in a variety of biological processes. However, the effects of CHR׳s cardioprotection in DOX-induced cardiomyopathy is poorly understood. In this study, we found that the cardiac apoptosis, mitochondrial injury and cellular PARylation levels were significantly increased in H9C2 cells treated by Dox, while these effects were suppressed by CHR. Similar results were observed when PARP1 activity was suppressed by its inhibitors 3-aminobenzamide (3AB) and ABT888. Ectopic expression of PARP1 effectively blocked this CHR׳s cardioprotection against DOX-induced cardiomyocyte injury in H9C2 cells. Furthermore, pre-administration with both CHR and 3AB relieved DOX-induced cardiac apoptosis, mitochondrial impairment and heart dysfunction in Sprague-Dawley rat model. These results revealed that CHR protects against DOX-induced cardiotoxicity by suppressing cellular PARylation and provided critical evidence that PARylation may be a novel target for DOX-induced cardiomyopathy.

Objective To investigate the correlation between serum miR-320b and carotid atherosclerosis in patients with acute ischemic stroke.Methods From January 2017 to December 2017,patients with acute ischemic stroke visited the Department of Neurology,the Affiliated Hospital of Yangzhou University were enrolled.According to the findings of carotid artery ultrasonography,they were divided into plaque group and plaque-free group.The baseline clinical data such as demographic data,vascular risk factors,and blood biochemical indicators were collected.Reverse transcription quantitative polymerase chain reaction was used to detect the expression level of serum miR-320b.Multivariatelogistic regression analysis was used to determine the independent risk factors for carotid atherosclerosis.Results A total of 135 patients with acute ischemic stroke were enrolled in this study,including 58 females and 77 males,aged 58.4 ± 10.6 years.There were 85 patients in the plaque group and 50 in the plaque-free group.The total cholesterol (t =5.523,P =0.023) and low-density lipoprotein cholesterol (t =4.415,P =0.044) in the plaque group were significantly higher than those in the plaque-free group,while high-density lipoprotein cholesterol (t =5.849,P=0.017) and serum miR-320b (t =4.331,P=0.039) were significantly lower than those in the plaque-free group.Multivariate logistic regression analysis showed that referring to the highest quartile group,the low serum miR-320b level might be an independent risk factor for carotid atherosclerosis (the first quartile group:odds ratio 2.701,95％ confidence interval 1.154-6.321,P =0.022;the second quartile group:odds ratio 2.521,95％ confidence interval 1.249-5.091,P =0.010;and the third quartile group:odds ratio 1.849,95％ confidence interval 1.041-3.283,P=0.036).Conclusion The low serum miR-320b level might be an independent risk factor for carotid atherosclerosis in patients with acute ischemic stroke.

Objective: To explore the correlation of non-coding RNA and the tumor-associated antigen midkine (MK) in SKOV3cells and the clinical significance for diagnosis of ovarian cancer. Methods: The Agilent′s gene chips (miRNAs chip and lncRNAs chip) were used to analyze the differential expression of miRNAs and lncRNAs in both MK-overexpressing SKOV3-MK cells and the control SKOV3-Con cells to screen the potential biomarkers in ovarian cancer. The clinical significance of midkine in the serum and tissues samples was analyzed for the patients with ovarian cancer by quantitative PCR combined with clinical data. Results: Compared with control SKOV3-con cells, MK overexpression significantly promoted the expressions of 11 miRNAs and 7 lncRNAs in SKOV3 cells (P＜0.01, ratio＞3 fold), reduced the expressions of 8 miRNAs and 13 lncRNAs (P＜0.01, ratio＜0.3). Results of qPCR showed that the expression level of miR489 was significantly lower in ovarian cancer tissues than that of the contralateral normal ovarian tissues, while HOTAIR was significantly elevated (P＜0.05). The expression level of HOTAIR in the serum of ovarian cancer patients was significantly higher than that in healthy controls group with same age (0.036±0.024 vs 0.019±0.020, P=0.002). ROC curve analysis of HOTAIR showed that the specificity was 66.7%, the sensitivity was 75.6% and the AUC value was 0.749 as a marker for serum detection of ovarian cancer when the cutoff value was 0.017 6. Conclusion Long-chain non-coding RNA HOTAIR may be served as a potential biomarker in serum of ovarian cancer patients.
