The incidence of psycho-cardiological diseases, i.e., cardiovascular diseases combined with psychological disorders, is increasing year by year. Brain-derived neurotrophic factor (BDNF) plays a role in the pathogenesis of such diseases. According to the theory of collateral diseases, our team innovates the concept of regulating mental activity by dredging collaterals in the treatment of psycho-cardiological diseases and summarizes the concepts of "heart of Qi and collaterals" and "heart of vessels and collaterals". We believe that obstructed collaterals and disturbed mental activity run through the whole course of psycho-cardiological diseases, being the core pathogenesis. BDNF closely related to the core pathogenesis can regulate nerve and vascular inflammation, alleviate oxidative stress, and mediate a variety of signaling pathways, thereby promoting the survival and repair of nerve cells and vascular endothelial cells to regulate emotion and protect the heart. Therefore, BDNF is one of the potential biomarkers for clinical treatment of psycho-cardiological diseases. Collateral obstruction caused by blood stasis is specifically manifested as collateral deficiency, blood stasis, and Qi stagnation in collaterals. It can easily lead to inflammation, free radical generation, and antioxidant system changes in the patients with psycho-cardiological diseases, which can cause oxidative stress damage, affect the BDNF level, and result in mental disorders, such as anxiety and depression. Disturbed mental activity is mainly caused by the disturbance in the heart of Qi and collaterals, which is specifically manifested as the disturbance of the mind and liver soul. It is prone to cause anxiety or depression symptoms, which is closely related to the BDNF-mediated abnormal activation of neural circuits, nerve injury, and inflammation. This article elaborates on the theoretical connotation and pathological mechanism of regulating mental activity by dredging collaterals in the treatment of psycho-cardiological diseases from the perspective of BDNF, aiming to provide new ideas for the prevention and treatment of psycho-cardiological diseases and collateral diseases.

Objective To investigate the correlations of computed tomography (CT), clinical, and pathological features in patients with invasive lung adenocarcinoma positive and negative for spread through air spaces (STAS). Methods A total of 236 patients with invasive lung adenocarcinoma confirmed by surgery and pathology were selected, including 118 patients in STAS-positive group and 118 patients in STAS-negative group. The clinical data, CT signs, and pathological features of the two groups were collected and analyzed. Results There was a correlation between age and the occurrence of STAS. The age of the positive group was higher than that of the negative group. Smoking history and family history of tumor had no correlation with the occurrence of STAS. CT features signs such as nodule type and shape, tumor-lung interface, lobulation sign, spiculation sign, vacuole/cavity, air-bronchogram, pleural indentation sign, vascular changes, mean diameter of tumor, mean diameter of solid component, and the percentage of tumor solid components were significantly different between patients with and without STAS. The incidence of STAS in patients with solid nodules and partial solid nodules was significantly higher than that in patients with ground glass nodules. Multivariate analysis showed that the percentage of tumor solid components, air-bronchogram sign, lobulation sign, and tumor-lung interface were independent risk factors for predicting the occurrence of STAS. Conclusion The clinical data and CT signs of patients with invasive lung adenocarcinoma are related to the occurrence of STAS. CT signs such as the percentage of tumor solid components, air-bronchogram, lobulation sign, and tumor-lung interface are of great significance to STAS prediction. Our findings provide an important basis for selection of personalized clinical treatment plans.

OBJECTIVES:
To systematically evaluate the value of the platelet-to-lymphocyte ratio (PLR) in predicting coronary artery lesions (CAL) in Chinese children with Kawasaki Disease (KD).
METHODS:
A comprehensive search was conducted in databases including PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, Wanfang Data, China Biomedical Literature Database, and China Science and Technology Journal Database from inception to December 2022. The quality of the included literature was assessed using the Newcastle-Ottawa Scale, and a Meta analysis was performed using Stata 15.1.
RESULTS:
A total of ten published reports, involving 3 664 Chinese children with KD, were included in this Meta analysis, of whom 1 328 developed CAL. The Meta analysis revealed a sensitivity of 0.78 (95%CI: 0.71-0.83), specificity of 0.71 (95%CI: 0.61-0.80), overall diagnostic odds ratio of 8.69 (95%CI: 5.02-15.06), and an area under the curve of the summary receiver operating characteristic of 0.82 (95%CI: 0.78-0.85) for PLR in predicting CAL in the children with KD. The sensitivity, specificity, and area under the curve of summary receiver operating characteristic were lower for PLR alone compared to PLR in combination with other indicators. Sensitivity analysis demonstrated the stability of the Meta analysis results with no significant changes upon excluding individual studies. However, a significant publication bias was observed (P<0.001).
CONCLUSIONS
PLR demonstrates certain predictive value for CAL in Chinese children with KD.

Coronary heart disease (CHD) with atherosclerosis is a common chronic disease worldwide, and anxiety and depression are potential and crucial risk factors for adverse prognosis in CHD. Chaihu Longgu Mulitang (CLMT), first mentioned in the Shang Han Lun (《伤寒论》), is a classic prescription for treating Shaoyang diseases combined with disturbance of the mind and spirit, with the effects of harmonizing Shaoyang and calming the mind. Current research on mechanisms has shown that CLMT can play a role in CHD complicated with anxiety and depression through multiple pathways, including regulating related signaling pathways, inhibiting the expression of inflammatory factors, improving oxidative stress damage, modulating neurotransmitter levels, suppressing the hypothalamic-pituitary-adrenal axis, promoting mobilization of mesenchymal stem cells from the bone marrow, and inhibiting platelet activation. Clinical studies have demonstrated that CLMT significantly improves symptoms such as angina and insomnia caused by CHD complicated with anxiety and depression, effectively reduces negative emotions, improves traditional Chinese medicine (TCM) syndrome scores, and decreases levels of inflammatory factors. Furthermore, it has fewer adverse reactions and higher safety than conventional western medicine treatments. This article provides a review of the mechanisms and clinical studies of CLMT in the treatment of CHD complicated with anxiety and depression based on a comprehensive analysis of literature from the China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP, PubMed, and other databases in the past 15 years, in order to provide references for further research on the use of CLMT in the management of CHD complicated with anxiety and depression.

Primary signet ring cell carcinoma (SRCC) of the prostate is a rare neoplasm. However, its potential tumorigenic mechanism, clinicopathological features, and prognostic outcome have not been systematically described. To determine the pathogenic mechanism, we detected distributions of programmed cell death-ligand 1 (PD-L1), programmed death 1 (PD-1), and cellular components in the tumor microenvironment, including tumor-infiltrating lymphocytes (CD4 and CD8), tumor-associated macrophages (TAMs; CD163 and CD68), and tumor-associated fibroblasts (vimentin and alpha-smooth muscle actin [α-SMA]), in tumor tissues from four patients with primary prostatic SRCC compared with corresponding adjacent tissues and tumor tissues from 30 patients with prostate adenocarcinoma (PCa) by immunohistochemical staining. We found higher expression of PD-L1, CD163, and CD68 in primary SRCC specimens than that in both corresponding adjacent nontumor specimens and PCa specimens with different Gleason scores, indicating that TAMs may participate in the malignant biological behavior of primary SRCC of the prostate. For further analysis, we searched electronic journal databases and Surveillance, Epidemiology, and End Results (SEER) to identify 200 eligible patients including our four cases. According to Kaplan-Meier survival curve analysis, patients <68 years old, with radical prostatectomy (RP), Gleason score of 7-8, and lower clinical stage had longer overall survival (OS). Moreover, Cox multivariate analysis indicated that race (hazard ratio [HR] = 1.422), surgical approach (HR = 1.654), and Gleason score (HR = 2.162) were independent prognostic factors for OS. Therefore, primary SRCC of the prostate represents a distinct and aggressive subtype of prostate cancer associated with a higher distribution of PD-L1 and TAMs, which warrants further clinical investigation.

Osteoporotic vertebral compression fracture (OVCF) can lead to lower back pain and may be even accompanied by scoliosis, neurological dysfunction and other complications, which will affect the daily activities and life quality of patients. Vertebral augmentation is an effective treatment method for OVCF, but it cannot correct unbalance of bone metabolism or improve the osteoporotic status, causing complications like lower back pain, limited spinal activities and vertebral refracture. The post-operative systematic and standardized rehabilitation treatments can improve curative effect and therapeutic efficacy of anti-osteoporosis, reduce risk of vertebral refracture, increase patient compliance and improve quality of life. Since there still lack relevant clinical treatment guidelines for postoperative rehabilitation treatments following vertebral augmentation for OVCF, the current treatments are varied with uneven therapeutic effect. In order to standardize the postoperative rehabilitation treatment, the Spine Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized relevant experts to refer to relevant literature and develop the "Guideline for postoperative rehabilitation treatment following vertebral augmentation for osteoporotic vertebral compression fracture (2022 version)" based on the clinical guidelines published by the American Academy of Orthopedic Surgeons (AAOS) as well as on the principles of scientificity, practicality and advancement. The guideline provided evidence-based recommendations on 10 important issues related to postoperative rehabilitation treatments of OVCF.
