In response to the clinical needs of cancer treatment and rehabilitation, Professor Lin Hongsheng proposed the Wuzhi Wuyang (five treatments and rehabilitation) concept on the basis of years of clinical experience and the Guben Qingyuan (consolidate the foundation and clear the source) theory. Wuzhi Wuyang emphasizes the importance of treatment and rehabilitation and aims to provide personalized and stage-specific treatment and rehabilitation plans by integrating the advantages of traditional Chinese medicine (TCM) and modern medicine to achieve comprehensive life-cycle management for patients with cancer. The proposal of Wuzhi Wuyang has provided new ideas and methods for the treatment, prevention, and rehabilitation of cancer, along with valuable references for clinical practice and academic research. This article summarizes the connotation of Wuzhi Wuyang and its application in the comprehensive management of cancer prevention and treatment with TCM.

Approximately 30%-40% of epilepsy patients do not respond well to adequate anti-seizure medications (ASMs), a condition known as pharmacoresistant epilepsy. The management of pharmacoresistant epilepsy remains an intractable issue in the clinic. Its early prediction is important for prevention and diagnosis. However, it still lacks effective predictors and approaches. Here, a classical model of pharmacoresistant temporal lobe epilepsy (TLE) was established to screen pharmacoresistant and pharmaco-responsive individuals by applying phenytoin to amygdaloid-kindled rats. Ictal electroencephalograms (EEGs) recorded before phenytoin treatment were analyzed. Based on ictal EEGs from pharmacoresistant and pharmaco-responsive rats, a convolutional neural network predictive model was constructed to predict pharmacoresistance, and achieved 78% prediction accuracy. We further found the ictal EEGs from pharmacoresistant rats have a lower gamma-band power, which was verified in seizure EEGs from pharmacoresistant TLE patients. Prospectively, therapies targeting the subiculum in those predicted as "pharmacoresistant" individual rats significantly reduced the subsequent occurrence of pharmacoresistance. These results demonstrate a new methodology to predict whether TLE individuals become resistant to ASMs in a classic pharmacoresistant TLE model. This may be of translational importance for the precise management of pharmacoresistant TLE.

Objective:To explore the occurrence and influencing factors of post-burn psychological stress disorder in preschool children.Methods:This study was a multi-center cross-sectional survey. From January 2022 to February 2023, 85 preschool children (aged 1 to 6 years) with burns admitted to the Affiliated Hospital of North Sichuan Medical College, Nanchong Central Hospital, Suining Central Hospital, Guang'an People's Hospital, and Guangyuan Central Hospital who met the inclusion criteria were selected as respondents. A self-made general information questionnaire was used to investigate the children's general data including gender, age group, residential area, main caregiver and their education level, and family type, as well as the injury condition including cause of injury and burn severity. The Child Stress Disorders Checklist was used to investigate the occurrence of psychological stress disorder in children at 3 days to 1 month after injury, and the incidence rate was calculated. The children were classified according to their general data and injury condition, and the occurrence of psychological stress disorder in children at 3 days to 1 month after injury was recorded, and the influencing factors for post-burn psychological stress disorder in preschool children were screened.Results:A total of 85 questionnaires were distributed and 85 valid questionnaires were recovered, with an effective recovery rate of 100%. Among the children, there were 45 boys and 40 girls, with most children aged 1 to 3 years. There were slightly more children in rural areas than in cities. About half of the children were mainly cared for by their parents and grandparents, respectively, and the education level of the main caregivers was mainly high school/technical secondary school. The family type was mainly core family and extended family. The main cause of injury was hydrothermal scald, and the severity of burns was mainly moderate. The incidence rate of psychological stress disorder in this group of children at 3 days to 1 month after injury was 34.12% (29/85). There were statistically significant differences in the occurrence of psychological stress disorder in children with different age groups, causes of injuries, and burn severity at 3 days to 1 month after injury (with χ2 values??of 9.18, 7.80, and 25.47, respectively, P<0.05); there were no statistically significant differences in the occurrence of psychological stress disorder in children with different genders, residential area, main caregivers, main caregivers' education levels, or family types at 3 days to 1 month after injury ( P>0.05). Multivariate logistic regression analysis showed that age group and burn severity were independent influencing factors for the occurrence of psychological stress disorder in preschool children after burns (with odds ratios of 8.21 and 33.99, respectively, and 95% confidence intervals of 1.57-43.04 and 5.55-207.93, respectively, P<0.05), the older the child and the more severe the burn, the higher the possibility of the occurrence of psychological stress disorder. Conclusions:The incidence rate of psychological stress disorder is high in preschool children after burns. Age group and burn severity are independent influencing factors for the occurrence of post-burn psychological stress disorder in this type of children.

Objective:To summarize and evaluate the target and dose design of 125I seed brachytherapy treatment plan of pediatric borderline tumor in head neck region. Methods:Eleven patients underwent definitive 125I brachytherapy or combined with surgery in Peking University Hospital of Stomatology from January 2010 to December 2018 were retrospective analyzed. The target region was set by extending the tumor gross region by 0.5 to 1.0 cm. The prescription dose and activity ranged from 80 to 120 Gy and 18.5 MBq, respectively. The treatments were performed according to the plan under general anesthesia. Response and toxic reaction were recorded during follow-up. The preoperative and postoperative dosimetric results were compared; and the local control rate, objective response rate, complete response rate and acute toxic reaction rate were calculated. Results:There was no statistically significant difference between preoperative and postoperative dosimetric results ( P>0.05). The follow-up time ranged from 33 to 131 months, with a median of 48 months. The local control rate, objective response rate, complete response rate and acute toxic reaction rate were 100%, 100%, 71.4% and 81.8%, respectively. Conclusions:Under well-designed target and dose, 125I brachytherapy for treatment of pediatric borderline tumor in head neck region would bring ideal therapeutic and toxic outcomes, and could be regarded as a feasible therapy.

Objective:To explore the value of 18F-FDG PET/CT radiomics in predicting the cervical lymph node metastasis in salivary gland cancer. Methods:Sixty-eight patients with salivary gland carcinoma treated in the Peking University School and Hospital of Stomatology were retrospectively studied. They were randomly divided into training group ( n=40), validation group ( n=14), and test group ( n=14). The primary tumor lesions were semi-automatically delineated on PET images as regions of interest (ROIs) and the radiomic features were extracted from ROIs. After feature selection and dimension reduction, an artificial neural network (ANN) prediction model was constructed. The prediction performance of the model was assessed using receiver operating characteristic (ROC) curves, the area under ROC curves (AUC), accuracy, sensitivity, and specificity. Moreover, the performance of various models was compared using the Delong test. Results:The radiomic model yielded an AUC of 0.88 (95% CI: 0.78-0.95), a sensitivity of 75%, specificity of 92.3%, and accuracy of 88.2%. By contrast, the combined model constructed based on the clinical node status (cN) reported by PET/CT and radiomic features yielded an AUC of 0.97 (95% CI: 0.89-0.99), a sensitivity of 87.5%, specificity of 100%, and accuracy of 97.1%. The Delong test showed that there was a statistically significant difference between the combined model and cN ( Z=2.27, P<0.05), but there was no statistically significant difference between the radiomic model and cN ( P>0.05). Conclusions:The ANN model based on 18F-FDG PET/CT radiomics combined with cN reported by PET/CT can more accurately predict cervical lymph node metastasis in patients with salivary gland carcinoma.

Objective To investigate the efficacy and clinical value of balloon-assisted clipping for the treatment of giant unruptured intracranial aneurysms of internal carotid artery. Methods Patients with giant unruptured intracranial aneurysm of intracranial segment of internal carotid artery treated with balloon-assisted clipping in the Department of Neurosurgery, Xiangya Hospital, Central South University from September 2017 to May 2018 were enrolled retrospectively. The proximal internal carotid artery or the aneurysm neck were temporarily blocked by balloon, and then the aneurysm was clipped in the hybrid operating room. Demographic data, preoperative symptoms, aneurysm characteristics, position of balloon placement, intraoperative angiography, complications, and follow-up results were collected. Results A total of 12 patients with giant (diameter >2 cm) unruptured intracranial aneurysm of intracranial segment of internal carotid artery were enrolled. They were all successfully clipped using balloon-assisted clipping in the hybrid operating room. Among them, 1 was located in the ophthalmic segment, 3 in the supraclinoid segment, 4 in the posterior communicating segment, 2 in the anterior choroidal artery segment, and 2 in the bifurcation of the internal carotid artery. The balloons were placed in the proximal end of internal carotid artery in 9 cases and in the neck of aneurysm in 3 cases. Intraoperative angiography showed that 12 aneurysms were completely occluded; 1 had severe stenosis of parent artery, and 1 had mild stenosis. Postoperative complications included cerebral infarction in 1 case, temporary diabetes insipidus in 1 case (returned to normal 1 week after operation), hemiplegia in 1 case, and epilepsy in 1 case. Glasgow Outcome Scale score at discharge showed 5 in 9 cases, 4 in 2 cases, and 3 in 1 case. The patients were followed up for 2.3 to 12 months after operation (median 7.5 months). Reexamination of CT angiography showed no recurrence of aneurysm. Glasgow Outcome Scale score was 5 in 11 cases and 4 in 1 case. Conclusions The use of balloon-assisted clipping technique in the hybrid operating room for the treatment of giant intracranial segmental aneurysms of the internal carotid artery is safe and effective, and has a good long-term outcome.

Objective To establish and evaluate a rat model of nonarteritic anterior ischemic optic neuropathy (NAION).Methods The rats were randomly divided into control group (n=13), sham laser group (n=11) and NAION group (n=23). The right eye was set as the experimental eye. NAION model was induced by directly illuminating the optic nerve (ON) of the right eye with 532 nm green laser, after intravenous infusion with the photosensitizing agent Rose Bengal. Sham laser treatment consisted of illuminating the ON region with 532 nm laser without Rose Bengal injection. Rats in control group underwent no intervention. The appearance of optic disc was observed with funduscope at 12 hours, 1, 3, 7, 28 days post-illumination. The histologic changes in the retina and ON of the NAION model were evaluated qualitatively with hematoxylin and eosin (HE) staining and transmission electron microscopy. The retrograde-labeled retinal ganglion cells (RGC) were counted on photographs taken from retinal flat mounts in a masked fashion.Results The optic disc in NAION eyes were swollen 3 days after photodynamic treatment. HE-stained longitudinal ON sections of NAION revealed vacuolar degeneration on day 3 after induction. Besides, ultrastructural study showed axonal edema and collapsed sheaths in the ischemic optic nerve at the same time point after modeling. ON edema resolved 7 days after induction. The final results revealed optic disc atrophy, extensive axonal loss, severe glial scar, and RGC death in large numbers 4 weeks after modeling. There were no aforementioned manifestations in control and sham laser group. The RGC density of the right eyes was statistically significantly lower in NAION group than that in control group and in sham laser group (t=?14.142, ?14.088;P=0.000, 0.000). The survival rate of RGC was statistically significantly lower in NAION group than in control group and in sham laser group (t=?17.048, ?16.667;P=0.000, 0.000). There was no difference of RGC density and survival rate of RGC between control and sham laser group (t=0.050, 0.348;P=0.961, 0.731).Conclusion A rat model of NAION was established successfully by photodynamic treatments with Rose Bengal, which induce optic nerve damage and RGC death.

Objective To analyze the level of cardiac troponin I (cTnI) in children with left-to-right shunt congenital heart disease (CHD). Methods In this study, 146 children with secundum atrial septal (ASD) defect, 132 children with ventricular septal defect (VSD) and 300 healthy children were recruited. The levels of cTnI and N-terminal pro-brain natriuretic peptide (NT-proBNP) were measured and their correlation with clinical data was analyzed. Results The serum cTnI and NT-proBNP levels in both ASD and VSD patients were signiifcantly higher than those in normal children (H=3.89 and 5.27, P<0.01). The serum cTnI and NT-proBNP levels in VSD patients were signiifcantly higher than those in ASD patients (P<0.05). The ratio of pulmonary to systemic arterial pressure (Pp/Ps), pulmonary vascular resistance index (PVRI) and standardized left ventricular end diastolic volume in VSD patients were signiifcantly higher than those in ASD patients (P<0.05). Multiple regression analysis showed that Pp/Ps was signiifcantly correlated with cTnI in VSD patients. (β=0.81, SE=0.03, P=0.000). Conclusions Signiifcant volume and pressure overload due to a left-to-right shunt induce myocardial injury and could lead to irreversible myocardial remodeling in children with CHD. The serum cTnI level is a sensitive biomarker for myocardial damage in VSD patients.

Objective To evaluate the growth inhibition and apoptosis of human monocytic leukemia THP-1 cell line by using 5,8-dimethyl-2-β-hydroxyisovalerylshikonin (SK36) and explore its preliminary mechanism. Methods CCK colorimetric assay and cell counting was used to examine the growth inhibition of shikonin on THP-1 cells. The apoptosis of THP-1 cells was detected by Annexin V/PI double labeling. The activation of Caspase-3 apoptosis pathway was determined by FCM. The apoptosis and the necrosis of THP-1 cells were detected by the laser scanning confocal microscopy. Results When the THP-1 cells were treated with SK36 at 1.02 μg/ml for 24 h and 48 h, the growth inhibition was dose-dependent. The cell apoptotic rate of THP-1 cells treated with 1.02 μg/ml evaluated by FCM with Annexin V/PI double labeling staining were (40.61 ±2.13) % and (67.40±9.15) % at 24 h and 48 h after treatment, respectively, which were significantly higher than that of the control group [(16.97±0.61) %] ([ = 18.444, t = 9.528, P <0.01). SK36 could induce THP-1 cells apoptosis involving the activation of Caspase-3 (F= 323.61, P<0.01). Conclusion SK36 can induce human THP-1 cells to undergo apoptosis, and its primary mechanism was to activate the Caspase-3.
