ABSTRACT
Objective:To explore the effect of changes in BMI (ΔBMI) on left ventricular function in early breast cancer patients undergoing anthracycline chemotherapy.Methods:The clinical data of 170 breast cancer patients treated in the Lianyungang Oriental Hospital from January 2018 to October 2021 were retrospectively analyzed. The clinicopathological data and cardiac color doppler ultrasound examination results of the patients were collected. Single-factor and multiple-factor were used to analyze the risk factors of cardiotoxicity in patients after chemotherapy. ΔBMI was calculated and the receiver operating characteristic (ROC) curve was drawn; the cut-off value of the ΔBMI was measured to obtain the diagnostic accuracy.Results:Compared with before chemotherapy, the mean values of BMI, left ventricular end-diastolic volume (EDV), left ventricular end-systolic volume (ESV), left ventricular end-diastolic diameter (LVD), and left ventricular end-systolic diameter (LVS) were increased after chemotherapy, while left ventricular ejection fraction (LVEF) value was decreased. Before and after chemotherapy, the differences between BMI [(22.30±1.88) kg/m 2 vs. (23.59±2.32) kg/m 2] and LVEF [(63.69±4.69)% vs. (59.08±4.28)%] were statistically significant ( t = 3.40 and 4.98, all P < 0.05). The range of ΔBMI was 0-41.3%, and the range of the change of LVEF (ΔLVEF) was 0-15.9%. There was a significant correlation between ΔLVEF and ΔBMI ( r = 0.709, P < 0.001). The incidence of cardiotoxicity was 21.2% (36/170). Logistic regression analysis showed that BMI( OR = 1.639, 95% CI 1.263-2.127, P = 0.000) and ΔBMI ( OR = 1.147, 95% CI 1.071-1.228, P = 0.000) were independent risk factors for cardiotoxicity in early breast cancer patients undergoing anthracycline chemotherapy. According to the cardiotoxicity, the area under the ROC curve of ΔBMI and BMI was 0.757 and 0.687, respectively. When the ΔBMI value was 4.28%, the maximum Youden index was 0.399, the sensitivity was 0.750, and the specificity was 0.649. Conclusion:For breast cancer patients treated with anthracycline chemotherapy, ΔBMI can be used as an effective indicator for predicting cardiotoxicity; when ΔBMI exceeds 4.28%, the risk of cardiotoxicity is high.

Objective@#To investigate the predictive effect of interleukin-27clinical pathological factors on local tumor progression after microwave ablation of liver cancer.@*Methods@#Collection of blood samples from 102 patients with hepatic malignancies treated with microwave ablation from January 2014 to December 2016 in Department of General Surgery, Lianyungang Oriental Hospital of Xuzhou Medical University. There were 80 males and 22 females, aged 24 to 83 years old, mean (58.7±11.4) years old. Patient age, gender, hepatitis, tumor diameter, tumor number, tumor boundary, tumor type, tumor blood perfusion degree, liver Child-Pugh classification, whether liver cirrhosis and peripheral blood IL-27 concentration and tumor local progression relationship were analyzed.Detection of IL-27 concentration in peripheral blood using ELISA.The Youden index was calculated using the receiver operating characteristic curve (ROC) to obtain the best cutoff value for IL-27 levels.Patients were divided into 61 patients with high IL-27 (>498.45 pg/L) and 41 patients with low IL-27 (≤ 498.45 pg/L) with optimal cut-off value.Measurement data were expressed as mean ± standard deviation (Mean±SD), and comparison between groups was evaluated by t test; Comparison of count data was evaluated by chi-square test. Survival curves were plotted by Kaplan-Meier method and survival rates were calculated; Cox proportional hazard regression model was used for multivariate analysis.@*Results@#The total incidence of local tumor progression was 35.3% (36/102). The IL-27 value of 102 patients ranged from(34.92-1 014.87) pg/L.The ROC curve of IL-27 value was plotted based on 2-year tumor-free survival as the endpoint. The area under the curve was AUC of 0.714 (P=0.017). When the IL-27 value was 498.45 pg/L, the Youden index was the largest, the sensitivity was 0.682, and the specificity was 0.556.The 2-year disease-free survival rate of all patients was 64.2%.The 2-year disease-free survival rates of patients with high IL-27 and low IL-27 were 72.7% and 50.5%, respectively. Survival analysis by Kaplan-Meier method showed that the prognosis of patients with high IL-27 group was better than that of patients with low IL-27 group (χ2=5.991, P=0.014). Univariate analysis of tumor local progression was associated with tumor >3 cm (χ2=7.170, P=0.007), tumor adjacent to large vessels (χ2=9.301, P=0.002), and high degree of tumor perfusion (χ2=5.599, P=0.018), IL-27 high level (χ2=5.460, P=0.019). Cox proportional hazard model analysis of tumor>3 cm, tumor adjacent to large blood vessels, low IL-27 level was an independent risk factor for tumor progression.@*Conclusions@#The level of IL-27, tumor ≥3 cm and tumor adjacent large blood vessels are predictor of local tumor progression after microwave ablation of liver cancer. Patients with low IL-27 levels have a high rate of local tumor progression.

ABSTRACT
Objective To evaluate the effect of pulsed radiofrequency (PRF) on spinal adenosine triphosphate (ATP)-P2X4-NLRP3 signaling pathway in rats with neuropathic pain.Methods Forty healthy clean-grade adult male Sprague-Dawley rats,aged 2-3 months,weighing 220-260 g,were divided into 4 groups (n =10 each) using a random number table method:sham operation group (group S),neuropathic pain group (group NP),sham PRF group (group SPRF) and PRF group.Neuropathic pain was induced by chronic constriction injury to the left sciatic nerve of anesthetized rats.Rats received PRF treatment on 7th day after establishing the model in group PRF.The mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were measured before establishing the model (T0) and at 3,7,10,14,21 and 28 days after establishing the model (T1-6).The rats were then sacrificed and the spinal cord was removed for determination of P2X4 and NLRP3 expression (by Western blot) and interleukin-1beta (IL-1β),IL-2,IL-6 and tumor necrosis factor-alpha (TNF-α) contents (by enzymelinked immunosorbent assay).Results Compared with group S,the MWT and TWL were significantly decreased at T1-6,the expression of P2X4 and NLRP3 was up-regulated,and the contents of IL-1β,IL-2,IL-6 and TNF-α were increased in NP,SPRF and PRF groups (P＜0.05).Compared with group NP and group SPRF,the MWT and MWT were significantly increased at T3-6,the expression of P2X4 and NLRP3 was down-regulated,and the contents of IL-1 β,IL-2,IL-6 and TNF-α were decreased in group PRF (P＜0.05).Conclusion The mechanism by which PRF alleviates neuropathic pain is related to inhibiting ATP-P2X4-NLRP3 signaling pathway in rats.

ABSTRACT
Objective To study the relationship between fucoidans structure and their antioxidant activities. Method Fucoidans (HF) were extracted from Laminaria japonica and was separated by anion exchange chromatography on DEAE-Cellulose 52 column (2.5?40 cm), and two fractions HF1 and HF2 were obtained. Fucoidans of low molecular weight (LF) was made after hydrolysis of HF by hydrochloric acid and purification by ultrafiltration. Chemical methods and gas chromatography were used to analyse the sugar composition of these polysaccharides; and infrared spectrum was utilized to determine their structure. The activity of inhibiting hydroxyl radical (?O H ) was evaluated by means of Fenton reaction. Results In HF1, 18.834% uronic acid, 44.197% L-fucose, 31.193% D-galactose and 24.612% D-mannose were detected. As to HF2, 5.878% uronic acid, 81.119% L-fucose and 18.881% D-mannose were found. L-fucose content in LF was 13.033%, equal to 32.084% of that in HF 40.621%. Both in HF1 and LF, sulfate groups were at the C-2 and C-4 positions of L-fucose, while in HF2, sulfate groups only at C-4 position. The concentration of fucoidans inhibiting 50% ?O H (IC50) was 7.6, 5.2 and 8.9 mg/ml for HF, HF1 and HF2 respectively. Nevertheless, LF approximately lost this activity. Conclusion The molecular weight, content and composition of sugar and the combining sites of sulfate groups were found to be related with the activity of inhibiting ?O H radical in fucoidans.
