Glucose metabolic reprogramming is important in promoting the occurrence and development of malignant tumors and meeting the high demands of the malignant proliferation of tumor cells. An in-depth investigation of the mechanism of glucose metabolic reprogramming in lung cancer is important for the development of effective therapeutic strategies for lung cancer. Traditional Chinese medicine (TCM) is characterized by multiple components, targets, and pathways and can exert antitumor effects through multiple mechanisms. This article illustrates systematically the mechanism of action of Chinese herbal monomers and compound formulas regulating glucose metabolic reprogramming in lung cancer and explores deeply their regulatory effects on key enzymes of glycolysis and metabolism-related signaling pathways, and their potential in overcoming the drug resistance of lung cancer. It aims to provide a reference basis for the study of therapeutic targets and mechanisms of action of TCM in prevention and treatment of lung cancer and theoretical sources for the research and development of new medicines.

Objective:To study the variational trend in disease characteristics of patients with hepatitis B-related primary liver cancer (HBV-HCC) in the past five years.Method:A single-center retrospective cross-sectional analysis was performed to compare patients diagnosed with HBV-HCC from January 2012 to December 2016 (control group) and from January 2017 to December 2021 (observation group). The data of the study variables were extracted from the electronic medical record system of the hospital information system of the Second Hospital of Lanzhou University. The 1:2 propensity score matching was used to adjust potential confounding factors such as gender and age. Multivariate logistic regression analysis was used to study the factors affecting changes in disease characteristics of the HBV-HCC population in the observation group. GraphPad Prism 8.0 software was used to draw forest plots to intuitively display the effect size of the study variables in the logistic regression analysis.The t-test was used to compare normally distributed data between groups. The χ2 test was used for inter-group comparison. Results:A total of 1 717 eligible cases were collected, including 510 in the control group and 1 207 in the observation group. Compared with the control group, the number of newly diagnosed cases in the observation group increased by 2.36 times, and males were still the main onset population (83.3% vs. 82.7%). The median age of onset increased (51.9 vs. 53.5 years, P<0.001). 79.4% of HBV-HCC patients had not received antiviral therapy, and the proportion of HBeAg-negative patients increased (56.4%). The factors affecting HBV-HCC patients included family history of HBV ( OR=1.626, 95% CI: 1.181-2.238), family history of hepatocellular carcinoma ( OR=1.388, 95% CI: 1.013-1.901), hypoviremia ( OR=1.322, 95% CI: 1.046-1.671), abnormal alanine aminotransferase ( OR=1.545, 95% CI: 1.231-1.940), liver fibrosis ( OR=1.478, 95% CI: 1.153-1.894), liver cirrhosis ( OR=1.431, 95% CI: 1.128-1.815), and metabolic-related fatty liver disease ( OR=1.438, 95% CI: 1.116-1.815) after propensity score matching adjustment. The factors affecting HBeAg-positive patients were decreased ( OR=0.390, 95% CI: 0.389-0.617); however, the number of early HBV-HCC diagnoses was increased (12.7% vs. 19.3%, P=0.001). Conclusion:The characteristics of patient disease and occurrence of HBV-HCC are changing over the past five years. The risk of developing hepatocellular carcinoma in middle- to older male patients with chronic hepatitis B is increasing with familial history of HBV and hepatocellular carcinoma, HBeAg negativity, hypoviremia, abnormal alanine aminotransferase, liver fibrosis, cirrhosis, and metabolic-related fatty liver disease.

Objective:To explore any effect of electroacupuncture (EA) at the Baihui (DU20) and Dazhui (GV14) acupoints on the learning and memory of rats modeling cerebral palsy (CP), and on the miR-126 regulated VEGF/Notch1 pathway.Methods:Fifty-four male Sprague-Dawley rats 7 days old with an average weight of (20±5g) were randomly divided into a sham operation group, a model group, and an electroacupuncture group, each of 18. All except the sham operation group had a model of CP induced using left common carotid artery ligation combined with hypoxia. Twenty-four hours after successful modelling, the EA group received 14 sessions of electroacupuncture at the DU20 and GV14 acupoints, once every other day. On the 29th day, learning and memory ability were evaluated using a Morris Water Maze. The expression of vascular endothelial growth factors (VEGF and VEGFR-2) was detected using immunohistochemical staining. The levels of notch1 and hes1 protein were quantified using western blotting, and the expression of miR-126 RNA was quantified using reverse transcription polymerase chain reactions (RT-qPCRs).Results:Compared with the sham group, there was a significant decrease in the average learning and memory, and the level of miR126 in the model group, but a significant increase in the expression of VEGF and VEGFR-2 and the levels of notch1 and hes1. Significant improvement was observed in all of the measurements of the EA group compared with the model group.Conclusions:Electroacupuncture at the DU20 and GV14 acupoints can improve the ability of learning and memory of rats modeling CP. The mechanism may be related to regulation of the VEGF/notch1 pathway by miR-126 and its promotion of angiogenesis.

Objective To investigate the regulatory mechanism of Notch signaling pathway by YAP in non-alcoholic steatohep-atitis(NASH)liver fibrosis,and assess the intervention effect of Cigu Xiaozhi prescription in detoxification and phlegm treatment.Methods C57BL/6J mice were randomly divided into different groups,including a normal group,NASH liver fibrosis model group,verteporfin(VP)intervention group,VP+Chinese medicine(Cigu Xiaozhi prescription)low-dose group,VP+Chinese medicine high-dose group,and dimethyl sulfoxide control group.The methionine/choline-deficient diet combined with low-dose CCl4 was used to construct the NASH liver fibrosis model.The degree of liver fibrosis was evaluated using hematoxylin and eosin(HE)and Masson staining.Four protein factors associated with liver fibrosis were detected using enzyme-linked immunosorbent assay,and hydroxyproline levels in the mouse liver was determined using the alkaline water method.The localization of α-SMA,ColⅠ,YAP,and Notch1 proteins in the liver was determined using immunohistochemistry.Additionally,the mRNA and protein expression levels of the Notch signaling pathway molecules,namely Notch1/2,J agged1,and DLL4,were assessed using real-time quantitative PCR and Western blotting analyses,respectively.Results The HE and Masson staining results revealed that the liver cells of NASH liver fibrosis mice were swollen and the cytoplasm was transparent.Additionally,evident fibrosis was observed in the hepatic lobule,portal area,and sinus;it was accompanied by heightened levels of inflam-matory cell infiltration,a large number of fat droplets,and instances of local hepatocyte necrosis,dissolution,and cirrhosis.The four factors associated with liver fibrosis showed a substantial increase(P<0.01).α-SMA,ColⅠ,YAP,and Notch1 were localized in the cytoplasm of hepatocytes.YAP,Notch1/2,and Jagged1 were highly expressed in the liver(P<0.01)but were downregulated after intervention with VP and VP+high and low doses of Cigu Xiaozhi prescription(P<0.05).Meanwhile,DLL4 factor was upregulated in the VP+high-dose of Cigu Xiaozhi prescription group(P<0.05).Conclusion YAP may inhibit activation of the Notch pathway by downregulating Notch1/2 and Jagged1 and upregulating DLL4,thereby interfering with the occurrence of liver fibrosis in NASH.Treatment with Cigu Xiaozhi pre-scription may inhibit Notch signaling pathway activation by downregulating YAP,Notch1/2,and Jagged1 and upregulating DLL4 through its multi-components and multi-targets properties,ultimately slow the progression of liver fibrosis in NASH.

Objective:To construct and validate a risk prediction model for major complications 30 days after surgery in the elderly patients with hip fracture.Methods:A retrospective study was conducted to analyze the clinical data of 276 elderly patients with hip fracture who had been admitted to Department of Trauma and Orthopaedics, The Hospital Affiliated to Chengde Medical University from June 2019 to December 2021. There were 96 males and 180 females with an age of (74.5±9.3) years, and 139 femoral neck fractures and 137 intertrochanteric fractures. The outcome of this study was whether major complications occurred within 30 days after surgery. Multiple logistic regression analysis identified the risk factors for major complications in the elderly patients with hip fracture within 30 days after surgery. The forward step-by-step method and likelihood ratio test were used to screen the best prediction model. A nomogram was constructed to display the model. The stability and effectiveness of the model were evaluated by the receiver operating characteristic curve (ROC), Hosmer-Lemeshow goodness-of-fit test, clinical decision curve and clinical impact curve analysis.Results:Logistic regression analysis showed that decreased preoperative hemoglobin ( P< 0.05), time from admission to surgery >72 hours ( OR=3.001, 95% CI: 1.564 to 5.758, P<0.001), control of nutritional status (CONUT) score >4 points ( OR=3.394, 95% CI: 1.724 to 6.680, P<0.001), and age-adjusted modified frailty index (aamFI) >2 points ( OR=2.875, 95% CI: 1.548 to 5.339, P= 0.001), increased operation time ( OR=1.016, 95% CI: 1.006 to 1.025, P=0.001), and surgical bleeding >60 mL ( OR=2.373, 95% CI: 1.016 to 5.540, P=0.046) were independent risk factors for major complications within 30 days after surgery in the elderly patients with hip fracture. The area under the ROC curve in the logistic risk prediction model was 0.846 (95% CI: 0.799 to 0.889), and the results of Hosmer-Lemeshow goodness-of-fit test showed ( χ2=8.080, P=0.426). The clinical decision curve and clinical impact curve showed that the prediction model was accurate and effective. Conclusion:Based on the patients' preoperative hemoglobin, time from admission to surgery, control of nutritional status score, age-adjusted modified frailty index, operation time and surgical blood loss, this study has constructed successfully a risk prediction model for complications 30 days after surgery in the elderly patients with hip fracture which enables medical staff to predict the occurrence of major postoperative complications.

OBJECTIVE To screen the effective anti-depressant part from Coreopsis tinctoria and study its mechanism. METHODS The anti-depressant effects of 30％，50％，70％ and 90％ ethanol elution fractions from 75％ ethanol extract of C. tinctoria（CCTE）were investigated by tail suspension test and forced swimming test. Mice head-drop test ，reserpine antagonistic test，yohimbine toxicity enhancement test and in vitro monoamine oxidase （MAO） inhibition test were used to explore the mechanism of the relationship between the effective parts and 5-hydroxytryptamine （5-HT） and norepinephrine （NE） nerves. RESULTS The 50％ and 70％CCTE could significantly shorten the accumulative immobility time in tail suspension test and forced swimming test （P＜0.05 or P＜0.01），increase the number of head-shaking times （P＜0.01），reverse the eyelid ptosis ， hypothermia and immobility caused by hematopin （P＜0.05 or P＜0.01），and increase the number of dead mice caused by yohimbine toxicity （P＜0.01）. IC 50 of okanin （CCT-6），isookanin（CCT-7）and taxifolin （CCT-8）against MAO were 8.71，37.89 and 67.07 µmol/L，respectively. CONCLUSIONS The 50％ and 70％CCTE are the effective anti-depressant parts of C. tinctoria . Its anti-depressant effect may be related to the reinforcement of 5-HT and the activation of NE nerves. The inhibition of CCT- 6， CCT-7 and CCT- 8 against MAO may be one of the anti-depressant mechanism of C. tinctoria .

Objective:To investigate the value of logistic regression model based on the features of cone-beam breast CT (CBBCT) for the identification of benign and malignant masses in dense breast.Methods:The data of 106 patients (130 masses) with dense breast who underwent contrast-enhanced CBBCT examination and obtained pathological results from May 2011 to August 2020 were retrospectively analyzed as the training set. From August 2020, the data of 49 patients (54 masses) who met the same criteria were prospectively and consecutively collected and used as the validation set. Taking pathological results as the gold standard, the training set was divided into benign and malignant groups. The t-test, χ 2 test and Fisher′s exact test were used to compare the differences in CBBCT image characteristics between the two groups in the training set. A binary logistic regression model was established by multivariate analysis. ROC curves were used to assess the diagnostic efficacy of the model as a whole in the training and validation sets and the diagnostic efficacy of each feature in the model, and the cut-off value of the intensity (ΔCT) value was determined. The H-L method was used to test the goodness of fit of the model. Decision curve analysis (DCA) was drawn to validate the clinical power of the model. Results:Univariate analysis showed that the breast parenchymal background enhancement (BPE), shape, margin, lobulation, spiculation, density, calcifications, ΔCT value, enhancement pattern, non-mass enhancement, ipsilateral increased vascularity (IIV), and peripheral vascular signs had statistical difference between benign group and malignant group ( P<0.05). BPE, margin, ΔCT value and IIV were included in the multivariate analysis, the equation was logit( P′)=-8.510+0.830×BPE+0.822×margin+1.919× ΔCT+1.896 × IIV. The are a under curve of the model in the training set was 0.879 ( P<0.001) and in the validation set was 0.851 ( P=0.001). The are a under curve of BPE, margin, ΔCT value, and IIV in the diagnosis of malignant mass were 0.645, 0.711, 0.712, 0.775 (all P<0.05); the best cut-off value of ΔCT was 50.38 HU. The fit of this model was good ( P = 0.776). The DCA curve showed that when the risk threshold was 0.05-0.97, the net benefit rate was>0, and this model had some clinical value. Conclusion:The logistic regression model based on the features of CBBCT is helpful to distinguish benign and malignant masses in dense breasts.

In order to accurately implant the brain electrodes of carp robot for positioning and navigation, the three-dimensional model of brain structure and brain electrodes is to be proposed in the study. In this study, the tungsten electrodes were implanted into the cerebellum of a carp with the aid of brain stereotaxic instrument. The brain motor areas were found and their three-dimensional coordinate values were obtained by the aquatic electricity stimulation experiments and the underwater control experiments. The carp brain and the brain electrodes were imaged by 3.0 T magnetic resonance imaging instrument, and the three-dimensional reconstruction of carp brain and brain electrodes was carried out by the 3D-DOCTOR software and the Mimics software. The results showed that the brain motor areas and their coordinate values were accurate. The relative spatial position relationships between brain electrodes and brain tissue, brain tissue and skull surface could be observed by the three-dimensional reconstruction map of brain tissue and brain electrodes which reconstructed the three-dimensional structure of brain. The anatomical position of the three-dimensional reconstructed brain tissue in magnetic resonance image and the relationship between brain tissue and skull surface could be observed through the three-dimensional reconstruction comprehensive display map of brain tissue. The three-dimensional reconstruction model in this study can provide a navigation tool for brain electrodes implantation.
