Curcumae Rhizoma, derived from the rhizome of Curcuma phaeocaulis, Curcuma kwangsiensis and Curcuma wenyujin, was called Ezhu in China. In the past, Curcumae Rhizoma extracts were obtained through water decoction or alternative methods, which showed significant anti-cancer effects. However, the mixed extracts contain various compound components of Curcumae Rhizoma, leading to an ambiguous mechanism of action for Curcumae Rhizoma extracts anti-cancer. Contemporary researchers have extracted the chemical components of Curcumae Rhizoma separately for experimental verification of its active ingredients in the anti-cancer field. Numerous studies demonstrated that curcumol, germacrone, β-elemene, and curcumin in Curcumae Rhizoma extracts have significant governing effects in anti-cancer activities. Pharmacological studies have shown that Curcumae Rhizoma suppresses cancer cell proliferation, invasion, and migration, triggering apoptosis and regulating cellular autophagy to achieve anticancer effects. Here, we summarized the research progress of Curcumae Rhizoma on anti-cancer effects from 2013 to 2022, aiming to explore the deeper molecular mechanisms of Curcumae Rhizoma's active components in cancer treatment.

Objective To investigate the effect and mechanism of microRNA-10b(miR-10b)on idiopathic short stature(ISS).Methods A total of 54 children with ISS and 54 healthy children were collected.The serum expression of miR-10b was detected by RT-qPCR,and the relationship between serum miR-10b expression and clinical data of children with ISS was analyzed.miR-10b inhibitor,si-TGFBR1 and their negative control transfection C28/I2 cells were used.CCK-8 experimental detection was used to detect C28/I2 cell proliferation.Western blot assay was used to detect gnome related transcription factor 2(RUNX2),collagen type X alpha 1 chain(COL10A1),transforming growth factor beta receptor 1(TGFBR1),SMAD3 and pSMAD3 protein expression.The target of miR-10b was screened in StarBase database,and the targeting relationship between miR-10b and TGFBR1 was verified by dual luciferase reporter gene assay.Results The serum expression of miR-10b was higher in the ISS group than that of the healthy control group,and the higher the miR-10b expression,the more obvious the decrease of child height,IGF-1 and alkaline phosphatase(P＜0.05).Compared with the NC group,the cell proliferation ability and RUNX2,COL10A1,TGFBR1,and pSMAD3 protein expression were up-regulated in the miR-10b inhibitor group(P＜0.05).StarBase database suggested that miR-10b had a binding site of TGFBR1,and dual luciferase reporter gene assay confirmed that TGFBR1 interacted with miR-10b(P＜0.05).Compared with the si-NC group,the expression of TGFBR1 was down-regulated and the cell proliferation ability was decreased in the si-TGFBR1 group(P＜0.05).Conclusion miR-10b inhibits chondrocyte proliferation and hypertrophy in idiopathic short stature by targeting TGFBR1/SMAD3 pathway.

Objective:To construct a machine-learning model for predicting the progression of pancreatic cystic lesions (PCLs) based on clinical and CT features, and to evaluate its predictive performance in internal/external testing cohorts.Methods:Baseline clinical and radiological data of 200 PCLs in 177 patients undergoing abdominal thin slice enhanced CT examination at Peking Union Medical College Hospital from July 2014 to December 2022 were retrospectively collected. PCLs were divided into progressive and non-progressive groups according to whether the signs indicated for surgery by the guidelines of the European study group on PCLs were present during three-year follow-up. 200 PCLs were randomly divided into training (150 PCLs) and internal testing cohorts (50 PCLs) at the ratio of 1∶3. 15 PCLs in 14 patients at Jinling Affiliated Hospital of Medical School of Nanjing University from October 2011 to May 2020 were enrolled as external testing cohort. The clinical and CT radiological features were recorded. Multiple feature selection methods and machine-learning models were implemented and combined to identify the optimal machine-learning model based on the 10-fold cross-validation method. Receiver operating characteristics (ROC) curve was drawn and area under curve (AUC) was calculated. The model with the highest AUC was determined as the optimal model. The optimal model's predictive performance was evaluated on testing cohort by calculating AUC, sensitivity, specificity and accuracy. Permutation importance was used to assess the importance of optimal model features. Calibration curves of the optimal model were established to evaluate the model's clinical applicability by Hosmer-Lemeshow test.Results:In training and internal testing cohorts, the progressive and non-progressive groups were significantly different on history of pancreatitis, lesions size, main pancreatic duct diameter and dilation, thick cyst wall, presence of septation and thick septation (all P value <0.05) In internal testing cohort, the two groups were significantly different on gender, lesion calcification and pancreatic atrophy (all P value <0.05). In external testing cohort, the two groups were significantly different on lesions size and pancreatic duct dilation (both P<0.05). The support vector machine (SVM) model based on five features selected by F test (lesion size, thick cyst wall, history of pancreatitis, main pancreatic duct diameter and dilation) achieved the highest AUC of 0.899 during cross-validation. SVM model for predicting the progression of PCLs demonstrated an AUC of 0.909, sensitivity of 82.4%, specificity of 72.7%, and accuracy of 76.0% in the internal testing cohort, and 0.944, 100%, 77.8%, and 86.7% in the external testing cohort. Calibration curved showed that the predicted probability by the model was comparable to the real progression of PCLs. Hosmer-Lemeshow goodness-of-fit test affirmed the model's consistency with actual PCLs progression in testing cohorts. Conclusions:The SVM model based on clinical and CT features can help doctors predict the PCLs progression within three-year follow-up, thus achieving efficient patient management and rational allocation of medical resource.

Objectives:To finely divide the aortic sinus into sections and accurately localize the coronary ostium through CARTO three-dimensional mapping,and to assess the clinical effects of treating aortic sinus cusps premature ventricular contraction(ASC-PVC)and the ablation risk in the corresponding area with zero X-ray radiofrequency ablation. Methods:A total of 66 patients who underwent radiofrequency ablation for ASC-PVC from January 2020 to January 2023 were included in this analysis,patients were divided into experimental group(n=34)and conventional group(n=32).In the conventional group,the CARTO 3 system was used to create an aortic sinus model through the conventional method.The earliest stimulating target was identified by using electrical stimulation mapping(ESM).Radiofrequency ablation treatment was performed after the distance between the target and the coronary ostium was precisely measured by coronary angiography through the hollow tube of the ablation catheter or coronary angiography tube.In the experimental group,the CARTO 3 system was used to build a model of the aortic sinus and the coronary ostium and aortic sinus were divided into sections.The earliest stimulating target was identified by ESM.After localizing coronary ostium through the impedance changing pattern on the ablation catheter tips,catheter ablation was performed with zero X-ray.The data regarding the impedance of the ablation catheter in the aortic sinus were collected.The total operative time,the operative time in the aortic sinus,contrast dosage,X-ray exposure time,immediate and short-term success rates of the operation and complication rates were compared between the two groups.Besides,the distribution of successfully ablated targets and their relationship with the risk of ablation were analyzed in both groups. Results:There was no significant statistical difference in the immediate and short-term success rates between the two groups(93.8%vs.94.1%;90.6%vs.88.2%,both P>0.05).The experimental group did not receive contrast agents during the operation,and the total operation time and intra-aortic sinus operation time in the experimental group were significantly shorter than those in the conventional group([58.76±4.94]min vs.[66.91±5.94]min,P<0.001;[43.12±4.49]min vs.[50.31±5.18]min,P<0.001).During the process of moving the ablation catheter from the intra-aortic sinus to the coronary artery opening and into the coronary artery,the impedance suddenly increased,which was significantly different from the impedance in other parts of the intra-aortic sinus(all P<0.001). Conclusions:Radiofrequency ablation of ASC-PVC with zero X-ray can simplify the procedures and shorten the operative time.The steep increase in impedance at the tip of the ablation catheter can be used as a basis for localizing the coronary ostium.Dividing the aortic sinus into sections allows a detailed assessment of the risk for ablation treatment at the targets.

Objective:To investigate the feasibility of coronary CT angiography(CCTA)-feature tracking(FT) for assessing global and regional myocardial strain in patients with heart failure(HF).Methods:From July 2019 to December 2020, twenty-five patients diagnosed with HF from Peking Union Medical College Hospital were prospectively enrolled into the study. All patients underwent retrospective electrocardiogram-gated CCTA and cardiac MR (CMR) imaging within 7 days. CCTA-FT and CMR-FT were undertaken using cvi 42 dedicated commercial software to measure global and regional strain parameters, including global peak radial strain (GPRS), global peak circumferential strain (GPCS) and global peak longitudinal strain (GPLS), as well as peak radial strain (PRS), peak circumferential strain (PCS) and peak longitudinal strain (PLS) of left ventricular basal segment, middle segment and apical segment. Conventional left ventricular functional parameters were also calculated, including left ventricular ejection fraction (LVEF), left ventricular stroke volume (LVSV) and left ventricular mass index (LVMI). Paired t test or Wilcoxon signed-rank test was used to compare the differences of measurements between CCTA group and CMR group. Pearson or Spearman correlation analysis was used to analyze the correlation between the two groups. Inter-and intra-observer consistence in CCTA group was evaluated by intraclass correlation coefficient (ICC) analysis. Results:The effective radiation dose of CCTA examination was 6.00 (4.86,7.63) mSv. Inter-and intra-observer consistence in CCTA group was excellent, and the ICC value was 0.85-0.98. In the overall strain parameters, GPCS in CCTA group[-8.10%(-10.32%, -5.20%)] was significantly lower than that of CMR group[-8.49%(-13.79%, -5.95%)] ( Z=-2.15, P=0.031). There was no significant difference in GPRS and GPRS between the two measurement methods ( P>0.05). Strong correlations were observed between GPRS, GPCS and GPLS ( r=0.65, 0.63, 0.71,all P<0.001). For local strain parameters, PCS in the middle segment and apical segment of CCTA group were lower than those of CMR group ( Z=-2.17, -2.62, all P<0.05). There were no significant differences in PCS of basal segment, PRS and PLS of all segments between groups (all P>0.05). The PCS and PLS of basal segment, PRS of middle segment and PRS of apical segment were moderately correlated ( r=0.46, 0.52, 0.58, 0.53, P<0.05); The other local strain parameters were strongly correlated, the range of r value was from 0.64 to 0.70 (all P<0.001). For left ventricular functional parameters, LVEF, LVSV and LVMI showed no significant differences between groups ( P>0.05), and the correlation was extremely strong ( r=0.90, 0.89, 0.96, all P<0.001). Conclusions:The repeatability of CCTA-FT technique in measuring myocardial strain was good, and the correlation of parameters measured by CCTA-FT technique and CMR-FT technique was excellent. Therefore, CCTA-FT technique can be used as a new noninvasive and simple method to evaluate myocardial motor function.

The proteolysis targeting chimeras (PROTACs) technology has been rapidly developed since its birth in 2001, attracting rapidly growing attention of scientific institutes and pharmaceutical companies. At present, a variety of small molecule PROTACs have entered the clinical trial. However, as small molecule PROTACs flourish, non-small molecule PROTACs (NSM-PROTACs) such as peptide PROTACs, nucleic acid PROTACs and antibody PROTACs have also advanced considerably over recent years, exhibiting the unique characters beyond the small molecule PROTACs. Here, we briefly introduce the types of NSM-PROTACs, describe the advantages of NSM-PROTACs, and summarize the development of NSM-PROTACs so far in detail. We hope this article could not only provide useful insights into NSM-PROTACs, but also expand the research interest of NSM-PROTACs.

Objective: To explore the value of quantitative CT radiomics features in predicting the anaplastic lymphoma kinase (ALK) mutation status in lung adenocarcinoma patients. Methods: This retrospective study reviewed one hundred and ninety-five lung adenocarcinoma patients (including 60 patients with ALK mutation) whose ALK genetic test results were available from Nov 2015 to May 2018 in PUMCH. VOIs were labeled by an automatic pulmonary nodule detection and segmentation algorithm and were later revised and confirmed by two senior radiologists. The PyRadiomics tools were used to resample the labeled regions, followed by image pre-processing (Wavelet filter or Laplacian of Gaussian (LoG) filter) and feature extraction. Normalized features were selected based on their representativeness on Dr. Wise research platform. Multivariate logistic regression was performed to develop prediction models of ALK mutation gene based on different image pre-processing techniques and different radiomics feature types. The results were validated by ten runs of five-fold cross validation. ROC curve analysis and Delong test were used to compare the predictive performance among models. Results: Fifteen radiomics features with the highest representativeness were selected from the original 1 232 features. The prediction model based on these radiomics features showed good performance (AUC=0.88 in the training set and 0.78 in the validation set) and was not significantly different from the prediction models based on radiomics features of different pre-processing images (AUC=0.76, P=0.1, original CT images; AUC=0.75, P=0.3, Wavelet-filtered images; AUC=0.76, P=0.2, LoG-filtered images). Among the models built with radiomics features of different types, the one based on GLCM feature (a subtype of texture feature) showed the best performance in predicting ALK genetic status (AUC=0.83, accuracy=0.74, sensitivity=0.85 and specificity=0.69). The model based on first-order statistic features had an AUC of 0.80. Conclusion Quantitative CT radiomics features have a good potential to anticipate the expression of ALK fused gene in patients with lung adenocarcinoma.

Objective To investigate the clinical,therapeutic and prognostic features of patients with lateral sinus stenosis and isolated intracranial hypertension,and further explore the possible mechanisms of their coexistence.Methods We retrospectively enrolled 16 patients with neurosurgery in our hospital from January 2009 to December 2016,who were clinically diagnosed as simple intracranial hypertension with bilateral or predominant lateral sinus stenosis and lateral stenting.These 16 patients were recorded surgical procedures and postoperative outcomes,and followed-up to understand the long-term prognosis of them.Results There were 14 females in the 16 patients,with an average age of (32.4 ± 10.1) years,a mean duration of (10.9 ± 7.3) months,and an average body mass index of (28.9 ± 3.6) kg/m2.In terms of clinical manifestions,majority of the patients presented with headache (n =15) and visual symptoms (n =14),and all with papilledema by fundus examination.The elevated opening cerebrospinal fluid (CSF) pressure was noticed:five cases between 25-33 cmH2O (1 cmH2O =0.098 kPa),11 cases more than 33 cmH2O.The mean pressure difference in the proximal and distal sinus of the anterior chamber was (36.3 ± 9.4) cmH2O in the range of 15-91 cmH2O.The pressure difference between the two ends of the stenosis disappeared immediately after the operation in 12 cases and the pressure difference less than 15 (2-12) cmH2O in four cases.Thirteen patients underwent lumbar puncture at one week after operation.The CSF pressure of them decreased significantly,of which eight were in the normal range.Six months after the operation,11 patients underwent DSA/MRV,none of which had serious surgical complications.With the average follow-up of (35.4 ± 9.8) months,the overall prognosis of these patients was good.Headaches in 14 of 15 patients were improved,out of which 12 were free of headache,two with only mild headache and a slight intracranial hypertension (19 and 23 cmH2O,respectively);visual complaints were reversed in nine out of 14 cases;10 patients underwent fundus examination,and nine of them were observed the improvement of papilledema.During the follow-up period,the symptoms of other patients were improved (headache relief and visual improvement) except one,the overall effective ratio being 15/16.Conclusions The interventional treatment of lateral sinus stenting is effective in patients with sinus stenosis associated with simple intracranial hypertension.The stenosis of the lateral sinus may be the main mechanism of increased intracranial pressure.
