Based on the theory of "sweet-flavored medicinals retaining and restoring body fluid"， this paper proposed that the core pathogenesis of hypercoagulable state in malignant tumors is qi deficiency and fluid consumption， blood stasis and vessels stagnation， which evolves dynamically according to the pattern "qi deficiency → fluid consumption → blood stasis". Accordingly， a staged treatment system is established with the general principle of "fortifying the middle jiao， restoring fluid and activating blood circulation". In the initial stage， invigorating the spleen and boosting qi to generate body fluid， targeting the onset of middle jiao deficiency and body fluid consumption； in the middle stage， nourishing yin and unblocking collaterals to facilitate body fluid circulation， addressing the disorder of body fluid transportation and collateral injury caused by internal dryness； in the late stage， consolidating yin and resolving blood stasis to retain body fluid， resolving yin impairment， fluid exhaustion， and binding of stasis and toxin. By regulating body fluid metabolism to improve the hypercoagulable state， this system is intended to provide insights for the prevention and treatment of hypercoagulable state in malignant tumors with traditional Chinese medicine.

Objective:To evaluate the value of prostate specific membrane antigen (PSMA) PET/CT-based radiomics models in differentiation between prostate cancer and benign prostatic hyperplasia (BPH).Methods:Data from 50 patients with prostate cancer (age: (70.0±8.8) years) and 25 patients with BPH (age: (66.9±9.4) years) who underwent 18F-PSMA-1007 PET/CT imaging and prostate biopsy in the First Affiliated Hospital of Xi′an Jiaotong University from May 2020 to September 2022 were retrospectively collected. Patients were divided into the training set ( n=53) and test set ( n=22) in the ratio of 7∶3 by using random seed number. The ROIs were delineated based on PET and CT images, and radiomics features were extracted respectively. Feature selection was performed using the minimum redundancy and maximum relevance (mRMR) and the least absolute shrinkage and selection operator (LASSO) algorithm. PET and PET/CT radiomics models were generated using logistic regression. ROC curve analysis was employed for model evaluation. In addition, comparisons of the 2 radiomics models with parameters including the ratio of free prostate specific antigen (fPSA)/total prostate specific antigen (tPSA), PET metabolic parameters, as well as prostate cancer molecular imaging standardize evaluation (PROMISE) were conducted (Delong test). Results:A total of 7 features were included in the PET radiomics model, and 3 CT-based features and 4 PET-based features were included in the PET/CT radiomics model. The AUCs of PET and PET/CT radiomics models in the training set and test set were 0.941, 0.914 and 0.965, 0.914, respectively, which were higher than those of fPSA/tPSA (0.719 and 0.710), SUV max(0.748 and 0.800), peak of SUV (SUV peak, 0.722 and 0.771), metabolic tumor volume (MTV, 0.640 and 0.595), total lesion uptake (TLU, 0.525 and 0.476) and PROMISE (0.644 and 0.667)[ z values for the training set: from -6.26 to -3.13, all P<0.01; z values for the test set: from -3.16 to -1.08, P>0.05 (fPSA/tPSA, SUV max, SUV peak) or P<0.05 (MTV, TLU, PROMISE)]. The differential diagnostic accuracy, sensitivity and specificity of PET and PET/CT radiomics models in the test set were 86.36%(19/22), 13/15, 6/7 and 90.91%(20/22), 15/15, 5/7, respectively. Conclusion:Compared with the clinical and PET parameters, PSMA PET/CT-based radiomics model can further improve the efficiency of differential diagnosis between prostate cancer and BPH.

Objective:Analyzing the relationship between negative life events and depressive symptoms in university freshmen,and the mediating effects of neuroticism and the moderating role of exercise frequency.Meth-ods:A sampling of 8 079 university freshmen,and the Patient Health Questionnaire was used to assess depressive symptoms,the Eysenck Personality Inventory-Neuroticism subscale to assess neuroticism,the self-administered questionnaire to assess the number of negative life events that the participants had experienced and the exercise fre-quency.Model 4 in the Process plug-in was used to test the mediating effect of neuroticism,and Model 7 to test the moderating role of exercise frequency.Results:The numbers of negative life events were positively correlated with the depressive symptoms scores(r=0.16,P＜0.01),and were positively correlated with the neuroticism scores(r=0.26,P＜0.01).The neuroticism scores were positively correlated with the depressive symptoms scores(r=0.52,P＜0.01).Neuroticism score partially mediated between negative life events and depressive symptoms score,with a mediating effect of 78.4％,and exercise frequency score moderated between negative life events and neuroti-cism scores(β=-0.05,P=0.032).Conclusion:Negative life events are associated with depressive symptoms,neuroticism plays a mediating role,and exercise frequency could moderate negative life events and neuroticism.

Pulmonary fibrosis (PF) is the pathological structure of incurable fibroproliferative lung diseases that are attributed to the repeated lung injury-caused failure of lung alveolar regeneration (LAR). Here, we report that repetitive lung damage results in a progressive accumulation of the transcriptional repressor SLUG in alveolar epithelial type II cells (AEC2s). The abnormal increased SLUG inhibits AEC2s from self-renewal and differentiation into alveolar epithelial type I cells (AEC1s). We found that the elevated SLUG represses the expression of the phosphate transporter SLC34A2 in AEC2s, which reduces intracellular phosphate and represses the phosphorylation of JNK and P38 MAPK, two critical kinases supporting LAR, leading to LAR failure. TRIB3, a stress sensor, interacts with the E3 ligase MDM2 to suppress SLUG degradation in AEC2s by impeding MDM2-catalyzed SLUG ubiquitination. Targeting SLUG degradation by disturbing the TRIB3/MDM2 interaction using a new synthetic staple peptide restores LAR capacity and exhibits potent therapeutic efficacy against experimental PF. Our study reveals a mechanism of the TRIB3-MDM2-SLUG-SLC34A2 axis causing the LAR failure in PF, which confers a potential strategy for treating patients with fibroproliferative lung diseases.

【Objective】 To analyze the correlation of whole body tumor burden of ¹⁸F-prostate specific membrane antigen positron emission computed tomography （¹⁸F-PSMA PET/CT） with prostate specific antigen （PSA） and Gleason score so as to evaluate the value of ¹⁸F-PSMA PET/CT whole body tumor burden for predicting serum PSA progression in prostate cancer. 【Methods】 We retrospectively recruited 213 patients with prostate cancer who underwent ¹⁸F-PSMA PET/CT scanning from March 2019 to April 2021. The serum PSA and Gleason score were collected. Whole body tumor burden was measured by a semi-automatic method. The correlation of tumor burden with serum PSA and Gleason score was analyzed. After radical prostatectomy， the patients were divided into groups according to negative or positive ¹⁸F-PSMA PET/CT. PSA differences between groups were compared， and the receiver operating characteristic curve （ROC） of the subjects was drawn so as to obtain the threshold value of PSA to predict the positive rate of ¹⁸F-PSMA PET/CT. The patients were followed up for PSA after radical surgery， divided into groups according to the progress of PSA， and the differences in tumor burden between groups were compared. 【Results】 In Gleason score ≤7， =8， and ≥9 groups， whole body tumor burden was correlated with PSA in each group （P=0.001）， and tumor burden significantly differed between the groups （P<0.001）. In initial diagnosis and treatment group， biochemical recurrence group， and medication group， the correlation between tumor burden and PSA was statistically significant （P=0.001）. The Gleason score of primary prostate lesion was significantly correlated with systemic tumor burden （P<0.001）. The area under ROC curve of PSA predicting the positive rate of ¹⁸F-PSMA PET/CT after radical prostatectomy was 0.821； when PSA>0.577 ng/mL， the sensitivity and the specificity were 66.7% and 96.8%， respectively. The mean whole body tumor burden in ¹⁸F-PSMA PET/CT positive patients with PSA progression was higher than that in patients without PSA progression. 【Conclusion】 The whole body tumor burden of ¹⁸F-PSMA PET/CT is significantly correlated with PSA， which is helpful in predicting the serum PSA progression in prostate cancer. PSA can predict the positive rate of ¹⁸F-PSMA PET/CT to a certain extent. At the same time， PSA can also predict positive results of ¹⁸F-PSMA PET/CT to a certain extent， and guide clinical rational selection of this examination.

【Objective】 To explore the surgical characteristics and clinical efficacy of percutaneous endoscopic visualization trephine for thoracic spinal stenosis. 【Methods】 We made a retrospective analysis of 37 patients with single-segment thoracic spinal stenosis treated with percutaneous endoscopic visualization trephine from January 2019 to June 2020. Among them， there were 14 males and 23 females； their age ranged from 31 to 82 years old， with an average of （57.6±11.8） years old. Their posture， length of hospital stay， length of operation and blood loss were recorded. The visual analogue scale （VAS）， Oswestry disability index （ODI） and the modified Japanese Orthopaedic Association （JOA） score were used to evaluate the preoperative and final conditions of patients and calculate the improvement rate. 【Results】 The operation was successfully completed in all the patients， and no patients developed epidural hematoma， incision infection or postoperative paralysis. Among the 37 patients， 24 ones with ossification of ligamentum flavum （OLF） were in the prone position， and 13 patients had lateral surgery. Among them， thoracic disc herniation （TDH） occurred in 3 cases， OPLL in 5 cases and OLF+OPLL in 5 cases. The hospital stay was （7.2±1.6） days， the operation time was （96.5±20.0） min， and the blood loss was （41.9±10.8） mL. VAS score decreased from （7.0±0.9） to （1.9±0.8）； ODI improved from （41.7±2.1） to （16.1±1.7）； and JOA score increased from （5.8±1.4） to （8.6±1.4）. The preoperative and postoperative differences were statistically significant （P<0.05）. 【Conclusion】 Percutaneous endoscopic visualization of thoracic spinal stenosis is treated by choosing different positions according to the type of compression. The spinal canal is fully decompressed. The surgical method is safe and minimally invasive， and the postoperative effect is satisfactory.

Objective:To explore the risk factors of adjacent segment diseases (ASDis) after lumbar fusion, summarize the prevention strategies and provide reference for clinical treatment.Methods:All of 258 patients who underwent lumbar interbody fusion from March 2014 to March 2019 were retrospectively analyzed, including 95 males and 163 females, the age of whom was 61.8±8.4 years (range, 39-77 years). The patients were divided into ASDis group and non-ASDis group according to whether ASDis occurred at the follow-up of 24 months after operation. The patient's individual factors [gender, age, body mass index (BMI), main diagnosis, preoperative paraspinal muscle fatty degree, etc.] and surgical factors (operation type, fixed segment, fusion segment, etc.), sagittal parameters [lumbar lordosis (LL), pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), PI-LL] were recorded. After univariate analysis of potential risk factors, the factors with P<0.05 were substituted into logistic regression model for multivariate analysis to determine the risk factors of ASDis after lumbar fusion. Results:ASDis occurred in 24 patients after lumbar fusion, with an incidence of 9.3% (24/258); univariate analysis showed that age ≥ 60 years old, complicated with osteoporosis, preoperative fatty degree of paraspinal muscle (GCS grade≥3), PLIF operation, suspension fixation, total laminectomy and multi-segment fusion (≥ 3 segments) were the potential risk factors for ASDis after operation (P<0.05); Gender, education level, partner status, type of work, BMI, obesity (BMI≥24 kg/m 2) , smoking, use of bisphosphonates, concomitant lumbar spinal stenosis, lumbar lordosis angle, pelvic incidence angle, pelvic tilt angle, sacral slope angle, and PI-LL had no significant correlation with ASDis. Logistic regression analysis showed that age ≥ 60 years ( OR=5.63, 95% CI: 1.56, 20.29, P=0.008), preoperative paravertebral muscle fatty GCS ≥ 3 ( OR=4.82, 95% CI: 1.36, 17.13, P=0.015), combined with osteoporosis ( OR=14.04, 95% CI: 2.53, 77.79, P=0.002), PLIF ( OR=9.69, 95% CI: 1.91, 49.03, P=0.001), and multi-segment fixation ( OR=9.36, 95% CI: 1.77, 49.41, P=0.008) were the risk factors for ASDis after lumbar fusion; Incomplete laminectomy ( OR=0.09, 95% CI: 0.02, 0.37, P=0.001) and suspension fixation ( OR=0.16, 95% CI: 0.02, 0.94, P=0.042) were the protective factors of ASDis after lumbar fusion. Conclusion:The patients with age ≥ 60 years old, osteoporosis and preoperative paraspinal muscle fatty degree ≥ 3 grade GCS should be more careful in choosing the surgical methods, and try to choose transforaminal interbody fusion, posterolateral fusion, short segment fusion, decompression with preservation of vertebral lamina, suspension fixation and other surgical methods to reduce the incidence of postoperative ASDis.
