ObjectiveTo investigate the mechanisms of Tongmai Yangxin pills (TMYX) and Tongxinluo capsules (TXL) in treating no-reflow (NR) after myocardial ischemia and reperfusion following the concept of treating the same disease with different methods, based on integrative pharmacology and experimental validation. MethodsEighty 8-week-old SPF-grade SD rats were randomly assigned into four groups (n=20): sham operation, NR, TMYX (4 g·kg-1), and TXL (2 mg·kg-1). A rat model of myocardial ischemia-reperfusion no-reflow was established by in-situ ligation of the left anterior descending coronary artery. Gastric gavage was first performed 4 h after the operation, and samples were collected on day 7. Thioflavin S staining was used to observe the NR area in rat myocardium. Echocardiography was performed to examine the cardiac function. Hematoxylin-eosin (HE) staining was conducted to observe the pathological changes of the myocardial tissue. An automatic biochemical analyzer was adopted to measure myocardial enzyme activity. Then, integrated pharmacology was applied for Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. Finally, Western blot was employed to quantify the protein levels of key targets in the myocardial tissue, including soluble guanylyl cyclase (sGC), cyclic guanosine monophosphate (cGMP)/dependent protein kinase (PKG), phosphorylated phosphatidylinositol 3-kinase (p-PI3K), phosphorylated protein kinase B (p-Akt), and hypoxia-inducible factor-1α (HIF-1α). ResultsCompared with the sham operation group, the NR group showed increased NR area of myocardium, decreased left ventricular ejection fraction (EF), left ventricular fractional shortening (FS), left ventricular outflow tract peak velocity (LVOT Peak), and left ventricular stroke volume (LVSV) (P<0.01), fractured and disordered myocardial fibers as well as inflammatory cell infiltration in the myocardial tissue, enhanced activities of creatine kinase (CK), creatine kinase isoenzyme (CK-MB), and lactate dehydrogenase (LDH) in the myocardial tissue (P<0.01), and downregulated protein levels of sGC, PKG, phosphorylated (p)-PI3K (Tyr458), and p-Akt (Tyr315) in the myocardial tissue (P<0.05, P<0.01). The expression level of HIF-1α protein showed a downward trend. Compared with the NR group, the TMYX group and TXL group exhibited a decreasing trend in myocardial NR area, EF, FS, and LVOT Peak significantly increased (P<0.05, P<0.01), LVSV showed an upward trend, ameliorated myocardial pathological morphology and inflammatory infiltration, reductions in CK, CK-MB, and LDH activities (P<0.05, P<0.01), and upregulated protein levels of sGC, PKG, p-PI3K (Tyr458) in myocardial tissue (P<0.05, P<0.01), the protein expressions of p-Akt (Tyr315) and HIF-1α showed an upward trend. A comparison of the therapeutic effects between the two compound prescriptions showed that TMYX tended to exert a better effect in restoring cardiac function and protecting cardiac structure in NR rats, whereas TXL was more effective in reducing myocardial NR area and lowering myocardial enzyme activities in NR rats. Integrative pharmacology analysis combined with experimental verification demonstrated that both TMYX and TXL could alleviate NR through the following mechanisms: activating the cyclic cGMP/PKG signaling pathway to regulate vascular tone, activating the PI3K/Akt signaling pathway to dilate blood vessels, and activating the HIF-1 signaling pathway to inhibit oxidative stress. However, TMYX had an advantage in activating the cGMP/PKG pathway, while TXL was superior in activating the PI3K/Akt pathway. The two compound prescriptions exerted comparable effects on the HIF-1 signaling pathway, which might serve as their common therapeutic pathway. ConclusionBoth TMYX and TXL could alleviate NR damage. TMYX exerts its protective effect against NR mainly by activating the cGMP/PKG signaling pathway, while TXL exerts its effect mainly through the PI3K/Akt pathway. The HIF-1α signaling pathway may be a common pathway for the two compound prescriptions to exert their protective effects against NR. This study reveals the similarities and differences between TMYX and TXL in the treatment effect and mechanism for NR, providing an experimental basis and a theoretical basis for better clinical application of the two compound prescriptions.

ObjectiveTo compare the Children's Hepatic tumors International Collaboration (CHIC) and the new Chinese Children's Cancer Group (CCCG) hepatoblastoma (HB) risk stratification systems in terms of their prognostic prediction efficacy and chemotherapy guidance value for Chinese children with HB, aiming to identify the risk stratification system more suitable for Chinese HB patients. MethodsThis retrospective study analyzed the clinical data of 403 pediatric patients with HB aged < 18 years who were initially diagnosed at The First Affiliated Hospital of Sun Yat-sen University between February 2010 and September 2023. The prognostic predictive efficacy and chemotherapy-guided value of the CHIC and CCCG risk stratification systems was compared. Statistical analysis was performed using SPSS 27.0. Results①Using the new CCCG risk stratification, the 5-year event-free survival (EFS) rates for children who received versus did not receive risk-stratified chemotherapy according to the CCCG-HB-2016 protocol were 82.5% and 67.7% (P=0.002), respectively, and the 5-year overall survival (OS) rates were 91.5% and 85.1% (P=0.038). Using CHIC risk stratification, the corresponding 5-year EFS rates for children who received versus did not receive risk-stratified chemotherapy according to the CCCG-HB-2016 protocol were 80.3% and 68.5% (P=0.030), and the 5-year OS rates were 90.9% and 85.8% (P=0.151). ②Among children treated with the CCCG-HB-2016 protocol stratified by the new CCCG system, the 5-year EFS rates for the very low-risk (6 cases), low-risk (20 cases), intermediate-risk (61 cases), and high-risk (69 cases) groups were 100%, 94.1%, 94.7%, and 66.2% (P<0.001), respectively, and the 5-year OS rates were 100%, 100%, 96.5%, and 82.0% (P=0.017). Among children treated with the CCCG-HB-2016 protocol stratified by the CHIC system, the 5-year EFS rates for the very low-risk (32 cases), low-risk (22 cases), intermediate-risk (37 cases), and high-risk (54 cases) groups were 93.8%, 95.2%, 76.1%, and 66.8% (P=0.003), respectively, and the 5-year OS rates were 93.1%, 100%, 89.5%, and 85.6% (P=0.190). ③For patients receiving CCCG-HB-2016 risk-stratified chemotherapy, the P-values for EFS comparisons between the CHIC and new CCCG systems within the very low-risk, low-risk, intermediate-risk, and high-risk groups were 0.537, 0.879, 0.023, and 0.934, respectively. Among patients who received stratified chemotherapy according to the CCCG-HB-2016 regimen, the intermediate-risk group in the new CCCG risk stratification system exhibited a significant advantage in 5-year event-free survival (EFS) compared with the intermediate-risk group in the CHIC risk stratification system (94.7% vs. 76.1%). ConclusionCompared to the CHIC risk stratification, the new CCCG stratification may offer better prognostic prediction and guidance value for chemotherapy in Chinese HB patients, with the intermediate-risk group showing superior outcomes.

Objective:To investigate the clinical effectiveness of Du Meridian moxibustion combined with brisk walking on negative symptoms, cognitive function, and social function in patients with stable schizophrenia, aiming to provide a feasible adjunctive treatment for clinical practice.Methods:A randomized controlled trial was conducted using convenience sampling to recruit 140 patients with stable schizophrenia hospitalized at the Affiliated Brain Hospital of Guangzhou Medical University from April 1, 2023, to March 31, 2024. Patients were randomly assigned to a control group, Du Meridian moxibustion group, brisk walking group, or combined group, with 35 patients in each group. The control group received standard care. On this basis, the Du Meridian moxibustion group received moxibustion on the Du Meridian, the brisk walking group participated in slow walking exercises, and the combined group received both interventions for 12 weeks. Assessments were conducted at baseline, at 6 and 12 weeks during the intervention, and at 12 weeks post-intervention using the Scale for the Assessment of Negative Symptoms, Mini-Mental State Examination, and Social Functioning Scale for Inpatient Psychiatric Patients.Results:A total of 134 patients completed the study: control group ( n = 34), Du Meridian moxibustion group ( n = 34), brisk walking group ( n = 35), and combined group ( n = 31). The combined group demonstrated significantly lower SANS scores at the 12th week of intervention (49.71 ± 4.66) and at 12 weeks post-intervention (53.45 ± 5.34) compared to the Du Meridian moxibustion group (54.91 ± 4.79) and (59.56 ± 5.84), the brisk walking group (56.69 ± 5.59) and (58.51 ± 5.42), control group (65.71 ± 4.95) and (66.21 ± 4.33), with statistically significant differences ( t values were 3.81-13.37, all P<0.05). Regarding cognitive function, the MMSE scores in the combined group at the 12th week of intervention (28.23 ± 1.28) and at 12 weeks post-intervention (27.35 ± 1.76) were higher than those in the Du Meridian moxibustion group (26.79 ± 1.85) and (25.59 ± 2.27) and the brisk walking group (25.88 ± 2.23) and (25.43 ± 1.84), control group (23.65 ± 2.17) and (22.32 ± 2.14), with statistically significant differences ( t values were - 10.28 to - 3.48, all P<0.001). For social function, the SSPI scores in the combined group at the 12th week of intervention (35.71 ± 3.63) and at 12 weeks post-intervention (32.58 ± 3.71) were also significantly higher than those in the Du Meridian moxibustion group (32.21 ± 3.91) and (28.47 ± 3.70) and the brisk walking group (31.83 ± 3.54) and (30.31 ± 3.59), control group (24.53 ± 4.12) and (24.15 ± 3.50) with statistically significant differences ( t values were - 11.56 to - 2.52, all P<0.05). Conclusions:The combination of Du Meridian moxibustion and brisk walking is an effective adjunctive intervention for patients with stable schizophrenia, as it significantly reduces negative symptoms, enhances cognitive function, and improves social functioning.

Objective:To analyze the safety and short-term efficacy of thoracic radiotherapy combined with anlotinib in the treatment of inoperable non-small cell lung cancer (NSCLC).Methods:A prospective study was conducted on patients with unresectable locally advanced NSCLC who were intolerant to concurrent chemoradiotherapy and treated at the Department of Radiation Oncology, Cancer Hospital, Chinese Academy of Medical Sciences, from October 2020 to September 2023. Anlotinib was administered orally concurrently with radiotherapy (days 1-14, 21 days per cycle, for 3 cycles). Adverse effects and short-term tumor recurrence were observed from the beginning of radiotherapy to the 3-month post-radiotherapy. Kaplan-Meier method was used to calculate progression-free survival (PFS) and overall survival (OS) rates from the date of initial treatment (induction therapy), and intergroup comparisons were performed using the log-rank test.Results:The median age was 62 years (range:42-76 years), with a male predominance ( n=36, 88%) of the included 41 patients. The incidence of grade 3-4 acute hematologic adverse events was 20% (8 cases); the incidence of grade 3 hemoptysis was 2% (1 case), with no grade 4 hemoptysis; the incidence of grade 3-4 radiation pneumonitis was 10% (4 cases). No grade 5 adverse events were observed in the entire cohort. With a median follow-up of 19.7 months (range: 7.1-50.1 months), 19 patients (46%) experienced recurrence, including 4 patients (10%) with local recurrence, 6 patients (15%) with regional lymph node recurrence, and 11 patients (27%) with distant metastases. The 1-year PFS rate was 78.3%. 8 patients (20%) died, including 3 patients died from COVID-19 infection during the follow-up period, 1 patient who died from hypostatic pneumonia due to prolonged bed rest after cerebral infarction, and 4 patients died from tumor-related causes. The 1-year OS rate was 78.0%. Conclusions:Thoracic radiotherapy combined with anlotinib demonstrates good safety, manageable adverse events, and favorable short-term efficacy in NSCNC patients intolerant to concurrent chemoradiotherapy.

Objective:To evaluate the role of a single PET-CT scan in predicting survival and prognosis in patients with non-small cell lung cancer (NSCLC) who did not undergo surgery but received radiotherapy after neoadjuvant chemotherapy combined with immunotherapy.Methods:A retrospective analysis was conducted on the data of 23 NSCLC patients treated at the Cancer Hospital of the Chinese Academy of Medical Sciences from May 2022 to June 2024. All patients were pathologically confirmed, received neoadjuvant chemotherapy combined with immunotherapy, did not undergo surgery for various reasons, and instead received radiotherapy. Each patient underwent only one PET-CT scan after neoadjuvant chemotherapy combined with immunotherapy and before radiotherapy. According to the maximum standardized uptake value (SUV max) on PET-CT, patients were divided into the low-uptake group (SUV max < 8, n=12) and high-uptake group (SUV max ≥ 8, n=11). Survival analysis was performed using the Kaplan-Meier method with survival curves plotted. Univariate analysis of influencing factors of survival was conducted using the Cox proportional hazards regression model. Clinical characteristics and survival outcomes of the two groups were compared, including progression-free survival (PFS) and overall survival (OS). Results:The 1-year PFS rates were 100% in the low-uptake group, 54.5% in the high-uptake group. This difference was statistically significant ( P=0.007). The 1-year and 2-year OS rates were both 100% in the low-uptake group, the 1-year and 2-year OS rates were both 90.9% in the high-uptake group, with no statistically significant difference ( P=0.394). Univariate Cox analysis identified age as an independent factor affecting PFS. Conclusions:For NSCLC patients who did not undergo surgical resection but received radiotherapy after neoadjuvant chemotherapy combined with immunotherapy, a single PET-CT scan before radiotherapy has potential value in predicting PFS. However, clinical studies with larger sample size and longer follow-up are required to evaluate its predictive value for OS.

Objective:To analyze the prognostic value of systemic inflammatory score (SIS) in patients with unresectable stage Ⅲ non-small cell lung cancer (NSCLC) treated by definitive chemoradiotherapy (dCRT) combined with or without consolidation immunotherapy with immune checkpoint inhibitor (ICI).Methods:The medical record data of 229 patients who received dCRT from January 2014 to December 2017 and 183 patients who received dCRT combined with any form of ICI (induction, concurrent, consolidation or combination) from August 2018 to August 2022 in the Cancer Hospital, Chinese Academy of Medical Sciences were retrospectively analyzed. Upon admission, 1 and 3 months after treatment (efficacy evaluation) and upon tumor recurrence, peripheral blood count was collected, and neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) and SIS were calculated, respectively. The SIS before, 1 and 3 months after treatment was defined as SIS 0, SIS 1 and SIS 3, respectively. Overall survival (OS) was considered as the primary endpoint. All patients were divided into dCRT group and dCRT+ICI group according to whether received immunotherapy, and then divided into different subgroups based on the cutoff value of SIS determined by X-Tile software. The prognostic value of SIS was evaluated by Kaplan-Meier survival analysis. The area under the receiver operating characteristic (ROC) curve (AUC) was used to evaluate the predictive efficiency. The predictive value of SIS was compared with inflammatory indexes (NLR, PLR) and independent prognostic factors. Results:In the dCRT group, the optimal cutoff value of SIS 0 was 590×10 9 and 530×10 9 in the dCRT+ICIs group. Univariate and multivariate analyses indicated that SIS 0 was an independent predictive factor of OS, progression - free survival (PFS), local - recurrence free survival (LRFS) and distant metastasis free survival (DMFS) in the dCRT group, but not associated with DMFS in the dCRT+ICI group. In the dCRT group, SIS 1>970×10 9 (optimal cutoff value) predicted poor OS ( HR=2.512, 95% CI=1.622-3.198, P<0.001), PFS ( HR=1.726, 95% CI=1.187-2.509, P=0.004), and DMFS ( HR=1.625, 95% CI=1.029-2.564, P=0.037). In the dCRT+ICI group, SIS 3>1570×10 9 (optimal cutoff value) indicated poor OS ( HR=5.107, 95% CI=1.731-15.069, P=0.003). In both groups, the AUC of SIS was higher than NLR, PLR and other traditional clinicopathological predictive indexes except T stage. Conclusions:SIS before treatment can be considered as an independent, dependable and easily acquired prognostic marker in patients with unresectable stage Ⅲ NSCLC treated by dCRT or dCRT+ICI. In the dCRT+ICI group, the optimal time point of post-radiotherapy SIS (3 months after treatment) is postponed than that (1 month after treatment) in the dCRT group.
