ObjectiveTo observe the analgesic efficacy and safety of Qihuang acupuncture theory combined with opioid analgesics in patients with moderate to severe cancer pain due to lung cancer. MethodsPatients with moderate to severe cancer pain from lung cancer were randomly divided into Qihuang acupuncture group and control group， with 33 cases in each group. The control group was treated with long-acting opioid analgesics at maintenance doses and supplementary analgesic medications as needed. In case of breakthrough pain， short-acting opioids were used for rescue. The Qihuang acupuncture group received Qihuang acupuncture treatment in addition to the treatment used in the control group， administered once every other day， with 3 sessions constituting one treatment course. The treatment duration for both groups was 5 days. The primary outcome was the change in pain intensity， measured using the numerical rating scale （NRS） before and after treatment， and the NRS change rate was calculated. Secondary endpoints included the daily NRS change rate， the Eastern Cooperative Oncology Group （ECOG） Performance Status （PS） score， the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire （EORTC QLQ-C30） score， and the 24-hour equivalent hydrocodone sustained-release tablet dose. Laboratory tests， including routine blood， urine， stool， liver function， and kidney function， were performed before and after treatment. Adverse events were recorded throughout the trial. ResultsAll patients completed the trial， and both groups showed a decrease in average NRS scores and PS scores after treatment， with the Qihuang acupuncture group showing lower average NRS scores and PS scores than the control group （P＜0.05 or P＜0.01）. After treatment， the NRS change rate in the Qihuang acupuncture group was （0.42±0.17）， significantly higher than that in the control group （0.14±0.27， P＜0.01）. The daily NRS change rate during treatment was also higher in the Qihuang acupuncture group compared to the control group （P＜0.01）. The Qihuang acupuncture group showed an increase in overall health status and functional scores in the EORTC QLQ-C30， and a decrease in symptom scores for fatigue， nausea and vomiting， pain， dyspnea， insomnia， appetite loss， constipation， and financial difficulties. In contrast， overall health status and constipation scores in the control group increased， while scores of fatigue， nausea and vomiting， pain， and appetite loss decreased （P＜0.05 or P＜0.01）. After treatment， the 24-hour equivalent hydrocodone sustained-release tablet dose did not show significant difference in the Qihuang acupuncture group （P＞0.05）， while the control group showed a significant increase in the 24-hour dose （P＜0.01）. No significant abnormalities were observed in laboratory tests before and after treatment in either group. During the study， the incidence of nausea and vomiting as well as constipation in the Qihuang acupuncture group was both 3.03% （1/33）， while the incidence in the control group was 27.27% （9/33） and 36.36% （12/33）， respectively， with the Qihuang acupuncture group showing significantly lower incidence （P＜0.01）. No serious adverse reactions were observed in either group. ConclusionQihuang acupuncture therapy combined with opioid analgesics is more effective than using opioids alone in relieving pain in patients with moderate to severe cancer pain due to lung cancer. It can improve the patients' physical condition and quality of life， reduce the dose of opioid analgesics， and has good safety.

Purpose To investigate the value of a radiomics model based on dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)in the differential diagnosis of granulomatous mastitis and breast cancer.Materials and Methods The MRI data of 82 patients with granulomatous mastitis or breast cancer confirmed by pathology in Xiyuan Hospital of China Academy of Chinese Medical Sciences from February 2019 to January 2022 were retrospectively collected.Based on the first phase of DCE-MRI,the regions of interest(ROI)were delineated layer by layer by semi-automatic segmentation method and manual segmentation method,respectively.99 ROI were randomly assigned to 69 in training groups and 30 in test groups.The consistency difference between the two methods was compared.The original data extracted by the semi-automatic segmentation method were screened by correlation analysis and multi-factor Logistic regression.Six kinds of classifiers(Logistic regression,support vector machine,naive Bayes,decision tree,random forest,K nearest neighbor)were used to construct prediction models,and the differences in diagnostic efficiency,accuracy,sensitivity and specificity of each model were evaluated.Results A total of 99 lesions(n=37 cases with granulomatous mastitis and n=62 cases with breast cancer)were segmented from 82 patients.The radiomics data extracted by the two ROI segmentation methods had poor consistency between groups[Intraclass correlation coefficient=0.68(0.51,0.78)].Among the six prediction models constructed from the data extracted by the semi-automatic segmentation method,the diagnostic performance of the Logistic regression model and the support vector machine model was significantly better than those of other models,and the Logistic regression model had the best diagnostic performance and stability(training group:area under the curve 0.928,accuracy rate 0.855,sensitivity 0.837,specificity 0.885;test group:area under the curve 0.933,accuracy 0.833,sensitivity 0.895,specificity 0.727,respectively).Conclusion Radiomics based on DCE-MRI can provide high value for the differential diagnosis of granulomatous mastitis and breast cancer.The semi-automatic segmentation method is more recommended for the segmentation method of ROI.The prediction model constructed by Logistic regression and support vector machine shows better diagnostic efficiency and stability.

【Objective】 To analyze the value of plasmin-α2-plasmin inhibitor complex (PIC) and thrombin-antithrombin complex (TAT) for risk stratification of massive transfusion (MT) in patients with postpartum hemorrhage (PPH). 【Methods】 Clinical data and blood samples of patients with PPH in our hospital from January 2019 to December 2022 were retrospectively analyzed. MT (MT group, n=60) was defined as transfusion of red blood cells≥10 U within 24 h after delivery, and <10 U was defined as non-MT group (n=190). Plasma PIC and TAT levels were detected by chemiluminescence immunoassay at the onset of PPH. 【Results】 Compared with non-MT group, PPH patients in MT group had higher TAT [2.20 (1.20, 3.00) ng/mL vs 4.00 (2.20, 6.30) ng/mL, Z=-5.464, P<0.001] and PIC [0.99 (0.82, 1.13) μg/mL vs 1.11 (1.05, 1.55) μg/mL, Z=-7.228, P<0.001] level. The analysis of receiver operator characteristic curve showed that the area under the curve required for MT after TAT and PIC combined to predict PPH was 0.820 (95% CI: 0.756-0.886), and the positive likelihood ratio was 4.76 and the negative likelihood ratio was 0.35, which was significantly better than the two predictions alone. Multivariate logistics regression analysis showed that TAT level>3.25 ng/mL and PIC level>1.04 μg/mL were independent risk factors for MT after PPH. 【Conclusion】 Elevated TAT and PIC levels are independent predictors of MT in patients with PPH, and their combined predictive efficacy is better.

Objective:To screen the interaction proteins of WW domain containing protein 1 (WWP1), and explore the effects of WWP1 and etoposide induced 24 (EI24) on cell proliferation in hepatocellular carcinoma (HCC).Methods:Yeast two-hybrid screening system was used to identify the interaction proteins of WWP1. The interaction was further validated by co-immunoprecipitation. WWP1 and EI24 stably over-expressing or deleted HepG2 cells were established by using the lentivirus transduction method. Colony forming assay and cell counting kit-8 (CCK8) assay were performed to identify the effects of WWP1 and EI24 on cell proliferation. In addition, the role of WWP1 in the tumorigenicity of liver cancer in vivo was examined by subcutaneous injection of different level of WWP1 expressed HepG2 into nude mice. Results:WWP1 can interact with EI24 and ubiquitin-degrade EI24 protein. The WWP1 and EI24 over-expressing or deleted HepG2 cell lines were successfully generated. Overexpression of WWP1 decreased while knockdown of WWP1 increased the protein level of EI24. The results of CCK-8 assay showed that the relative proliferation activities of WWP1 overexpressed (WWP1-OE) group and WWP1 knockdown (shWWP1) group on 36 hours were (347.00±8.15)% and (187.08±4.86)%, respectively, significantly different from (270.33±15.01)% of control group (both P<0.05). The relative proliferation activities of EI24 overexpressed (EI24-OE) group and EI24 knockdown (shEI24) group on 36 hours were (183.75±8.11)% and (317.33±9.60)%, respectively, significantly different from (270.33±15.01) % of control group (both P<0.05). The results of colony formation assay showed that the colony numbers of control group, WWP1-OE group and shWWP1 group were (52±7)/visual field (VF), (76±4)/VF, (19±3)/VF, respectively. Overexpression of WWP1 significantly increased while knockdown of WWP1 significantly decreased the colon formation ability of HepG2 cells (both P<0.05). The colon number of control group, EI24-OE group and shEI24 group were (38±4)/VF, (10±3)/VF, (69±7)/VF, respectively. Overexpression of EI24 significantly decreased while knockdown of EI24 significantly increased the colony formation ability of HepG2 cells (both P<0.05). The results of xenograft mice model showed that the tumor volumes of control, WWP1-OE, and shWWP1 group were (1 400.00±43.71)mm 3, (2 636.67±290.45) mm 3 and (642.17±36.00)mm 3, respectively, with significant differences ( P<0.05). The tumor weight for these three groups were (1.23±0.08)g, (2.05±0.17)g, and (0.88±0.09)g, respectively, with significant differences ( P<0.05). The tumor volumes of control, EI24-OE, and shEI24 group were (1 245.17±93.10)mm 3, (662.17±60.88)mm 3 and (1 986.67±226.75)mm 3 respectively, with significant differences ( P<0.05). The tumor weight for these three groups were (1.15±0.04)g, (0.85±0.02)g and (1.73±0.05)g respectively, with significant difference ( P<0.05). Conclusion:WWP1 promote the cell proliferation of liver cancer through ubiquitin-degradation of EI24.
