Objective:
To explore the network structure of middle school students basic psychological needs and psychological behavioral problems, and identify the core nodes within the network, as well as examine demographic subgroup differences, so as to provide support for targeted mental health interventions for adolescents.
Methods:
In September and October of 2023, a total of 2 000 junior and senior high school students were selected with multistage cluster random sampling from 8 schools in Jiaojiang District and Tiantai County, Taizhou City. An online self administered questionnaire was used to assess emotional and behavioral problems, perceived autonomy, self awareness, loneliness, and social support. The instruments included the Strengths and Difficulties Questionnaire (SDQ), Perceived Choice and Awareness of Self Scale (PCASS), Mental Health Literacy Questionnaire (MHLQ), University of California,Los Angeles Loneliness Scale (UCLA-LS), and the Multidimensional Scale of Perceived Social Support (MSPSS). A network analysis approach was employed to construct a network representing adolescents basic psychological needs and psychological behavioral problems, focusing on centrality measures and demographic subgroup differences.
Results:
A total of 418 students (20.9%) reported abnormal emotional and behavioral problems. Perceived autonomy and competence were negatively correlated with emotional problems (weights: 0.12, 0.14) and hyperactivity (weights: 0.10, 0.16). Social support showed negative correlation with peer relationship issues, hyperactivity, and conduct problems (weights: 0.16, 0.13, 0.10). Loneliness was positively correlated with emotional symptoms and peer relationship problems (weights: 0.28, 0.18). In the overall network, perceived relationships (social support and loneliness), emotional symptoms, and hyperactivity emerged as central nodes. Significant differences in network structure were observed between gender subgroups ( P =0.02). Girls internalizing issues were more influenced by loneliness and perceived autonomy frustration, while social support exhibited higher centrality in boys.
Conclusions
Perceived relationships, emotional problems, and hyperactivity are key nodes in the network of adolescents basic psychological needs and psychological behavioral problems. Loneliness demonstrates a prominent influence within the network, and the overall network exhibits gender differences.

ObjectiveTo investigate the mechanisms of Tongnao decoction (TND) in mice with acute ischemic stroke (AIS). MethodsFifty male C57BL/6J mice were randomly divided into a sham operation group, model group, TND low-dose group (1.86 g·kg-1), TND high-dose group (3.72 g·kg-1), and butylphthalide (NBP) group (10 mg·kg-1), with 10 mice in each group. A mouse model of cerebral ischemic injury was established using photochemical thrombosis (PT). The sham operation group and model group were administered an equal volume of normal saline by gavage. All five groups were treated once daily for 14 consecutive days. Behavioral tests were performed before modeling and at the end of administration. T2-weighted imaging (T2WI) was performed 3 days after modeling to evaluate the extent of injury. Hematoxylin-eosin (HE) staining was used to observe histological changes in the cerebral cortex, and Nissl staining was used to observe neuronal morphology. Cerebral blood flow in mice was detected using a laser speckle contrast imaging (LSCI) system. Immunofluorescence staining was used to detect the cell proliferation marker bromodeoxyuridine (BrdU) and the highly glycosylated type I transmembrane glycoprotein CD34. Western blot analysis was used to detect the expression levels of phosphatidylinositol 3-kinase (PI3K), protein kinase B (Akt), glycogen synthase kinase-3β (GSK-3β), and their phosphorylation levels, as well as tight junction-related proteins zonula occludens-1 (ZO-1), Occludin, and Claudin-5 in the peri-infarct tissue. Thirty-five zebrafish were randomly divided into normal control group, model group, TND low and high dose groups (0.16, 0.32 g·L-1) and NBP group (10 μmol·L-1), with 7 in each group. A stereoscopic fluorescence microscope was used to observe vascular growth in zebrafish. ResultsImaging showed that PT caused ischemia in the right cortical region. Behavioral tests indicated that, compared with the model group, the drug-treated groups reduced the error rate of irregular balance ladder climbing on the affected side and shortened the tape removal time (P<0.05). HE staining and Nissl staining showed that, compared with the model group, the drug-treated groups exhibited reduced brain tissue damage, fewer scars, and improved neuronal morphology. LSCI results showed that the drug-treated groups partially restored cerebral blood perfusion and promoted the establishment of collateral circulation compared with the model group. Immunofluorescence staining indicated that the drug-treated groups increased the positive rates of BrdU and CD34 compared with the model group (P<0.01), promoting angiogenesis. Meanwhile, compared with the model group, the drug-treated groups upregulated the expression levels of p-PI3K, p-Akt, p-GSK-3β, and tight junction proteins ZO-1, Occludin, and Claudin-5 (P<0.05,P<0.01), and increased the number of intersegmental vessels in zebrafish (P<0.05,P<0.01). ConclusionTND can promote angiogenesis around the infarct in PT model mice by regulating the PI3K/Akt/GSK-3β signaling pathway, thereby improving cerebral ischemic injury.

ObjectiveTo evaluate the effects and safety of the optimized new Shengmai Powder (优化新生脉散方) on exercise tolerance in patients with chronic heart failure (CHF) of qi deficiency, blood stasis, and fluid retention syndrome. MethodsA randomized, double-blind, placebo-controlled trial was conducted. A total of 78 CHF patients with qi deficiency, blood stasis, and fluid retention syndrome were recruited and randomly assigned to a treatment group (39 cases) and a control group (39 cases). On the basis of conventional western medical therapy, patients in the treatment group additionally received the optimized new Shengmai Powder granules, while the control group was given an oral placebo of optimized new Shengmai Powder granules. Patients in both groups took 30.6 g each time, twice a day, mixed with water for administration, with a total treatment course of 4 weeks. The primary outcomes were 6-minute walk distance (6MWD) and peak oxygen uptake (Peak VO2) measured by cardiopulmonary exercise testing. Secondary outcomes included New York Heart Association (NYHA) functional classification, B-type natriuretic peptide (BNP) levels, cardiac function indexes including left ventricular ejection fraction (LVEF), left ventri-cular end-systolic diameter (LVESD) and left ventricular end-diastolic diameter (LVEDD), Minnesota Living with Heart Failure Questionnaire (MLHFQ) scores, and scores of four diagnostic information of traditional Chinese medicine (TCM). All indicators were assessed once before and after treatment respectively. Safety indicators were evaluated, and adverse events during the trial were recorded. ResultsAll patients in both groups were included in the full ana-lysis set (FAS) and safety set (SS). Compared with baseline, the 6MWD and Peak VO₂ of cardiopulmonary exercise test in the treatment group significantly increased after treatment, while the MLHFQ scores, serum BNP levels and scores of TCM four diagnostic information significantly decreased, and the NYHA cardiac function grade significantly improved (P<0.01). After treatment, the 6MWD and Peak VO₂ of cardiopulmonary exercise test, as well as their changes from baseline in the treatment group were higher than those in the control group; the MLHFQ scores, serum BNP levels and scores of TCM four diagnostic information in the treatment group were lower than those in the control group; and the improvement of NYHA cardiac function grade in the treatment group was superior to that in the control group (P<0.01). There was no statistically significant differences in all indicators after treatment in the control group (P>0.05). The incidence of adverse events was 5.1% (2/39) in the treatment group and 2.6% (1/39) in the control group, with no statistically significant difference between groups (P>0.05). ConclusionOn the basis of conventional western medicine treatment, the addition of the optimized new Shengmai Powder can further improve exercise tolerance, cardiac function and quality of life in patients with CHF of qi deficiency, blood stasis and fluid retention syndrome, and show good safety.

ObjectiveTo explore the potential mechanism of Shenqi Jianxin Formula (参芪健心方) in the treatment of chronic heart failure (CHF) from the perspective of regulating mitochondrial autophagy via the PTEN-induced kinase 1 (PINK1)/E3 ubiquitin ligase (Parkin) pathway. MethodsMale SD rats were subjected to abdominal aortic constriction to establish the CHF model. Twenty-four successfully modeled rats were randomly divided into the model group, sacubitril/valsartan group, and low- and high-dose Shenqi Jianxin Formula groups, with 6 rats in each group. Six other rats were set as the sham surgery group, which were only separated the abdominal aorta and then closed the abdomen. Rats in the low-dose and high-dose Shenqi Jianxin Formula groups were given intragastric administration of Shenqi Jianxin Formula suspension at doses of 4.41 g/(kg·d) and 17.64 g/(kg·d), respectively; the sacubitril/valsartan group received intragastric administration of sacubitril/valsartan sodium tablet suspension at 10 mg/(kg·d); the sham surgery group and the model group were given normal saline at 10 ml/(kg·d) via intragastric gavage. The intervention lasted for 4 consecutive weeks. Cardiac function indices including left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) were detected, and serum brain natriuretic peptide (BNP) content was measured. HE staining and Masson staining were used to observe myocardial histopathological changes. Transmission electron microscopy was employed to examine the ultrastructure of cardiac tissues. Quantitative real-time polymerase chain reaction (Rt-qPCR) was performed to determine the mRNA expressions of PINK1/Parkin pathway-related factors and autophagy-associated proteins including Beclin-1, p62, and microtubule-associated protein 1 light chain 3 (LC3) in myocardial tissues. ResultsCompared with the sham surgery group, the model group showed significant decreases in LVEF and LVFS levels, an increase in serum BNP content, down-regulated mRNA and protein expressions of PINK1, Parkin and Beclin-1 in cardiac tissues, up-regulated mRNA and protein expressions of p62, as well as significant reductions in LC3B mRNA expression, phosphorylated PTEN-induced kinase 1 (p-PINK1) and phosphorylated E3 ubiquitin ligase (p-Parkin) protein levels, and the ratio of microtubule-associated protein 1 light chain 3-Ⅱ to microtubule-associated protein 1 light chain 3-Ⅰ (LC3Ⅱ/LC3Ⅰ) (P<0.05). Pathological results revealed obvious myocardial cell edema, necrosis and degeneration, increased disorder of myocardial fiber arrangement, extensive inflammatory cell infiltration, moderate to severe mitochondrial swelling, a few mitochondrial vacuolar changes, and no obvious autophagy in the field of vision in the model group. Compared with the model group, all the above indicators were significantly improved in the high-dose Shenqi Jianxin Formula group and the sacubitril/valsartan group (P<0.05). Moreover, the improvement of each index in the high-dose Shenqi Jianxin Formula group was superior to that in the low-dose group (P<0.05). In the high-dose Shenqi Jianxin Formula group, myocardial myofibrils were arranged regularly with orderly orientation, the striated structure was clear, and necrotic cells significantly reduced. ConclusionShenqi Jianxin Formula can activate the PINK1/Parkin signaling pathway in myocardial tissues, enhance mitochondrial autophagy, and clear dysfunctional mitochondria, thereby improving cardiac function and delaying the progression of CHF.

Objective To investigate the distribution characteristics of pathogens causing infections within 90 days after liver transplantation and the influencing factors of infection. Methods Clinical data of 176 recipients who underwent liver transplantation at the Liver Transplant Center of Beijing Friendship Hospital Affiliated to Capital Medical University from September 2021 to August 2024 were retrospectively analyzed. Patients were divided into the infection group (n=124) and the non-infection group (n=52) based on whether they developed infection within 90 days after transplantation. The distribution characteristics of pathogens in infected patients were analyzed. Univariate and multivariate logistic regression analyses were used to explore the influencing factors of infection. Results Among the 176 liver transplant recipients, 124 cases developed 243 episodes of 518 bacterial, fungal, viral or mycoplasma infections within 90 days after transplantation, with an overall infection rate of 70.5% (124/176). The composition of pathogens was mainly Gram-negative bacteria (38.6%, 200/518), followed by Gram-positive bacteria (32.2%, 167/518) and viruses (15.4%, 80/518), and fungi accounted for 13.1% (68/518). Among Gram-negative bacteria, the main pathogen was Klebsiella pneumoniae (6.8%, 35/518), and among Gram-positive bacteria, the main pathogen was Enterococcus faecalis (8.5%, 44/518). Viruses included Epstein-Barr virus (3.7%, 19/518) and cytomegalovirus (3.7%, 19/518), and fungi were mainly Candida albicans (6.8%, 35/518). The most common infection site among the 243 episodes was pulmonary infection (42.0%, 102/243), followed by abdominal infection (22.6%, 55/243) and bloodstream infection (18.1%, 44/243). The infections mainly occurred within 2 weeks after transplantation (60.9%, 148/243). Multivariate logistic regression analysis indicated that preoperative infection within 2 weeks, a high preoperative model for end-stage liver disease (MELD) score, and preoperative sarcopenia were independent risk factors for infection within 90 days after liver transplantation (all odds ratio>1, P<0.05). After multivariate correction, the levels of CD4+T cells and CD8+T cells within 90 days after surgery were independently associated with the occurrence of infection. Low levels of CD4+T cells and CD8+T cells might be related to an increased risk of infection. Conclusions The infection rate after liver transplantation is high, and the pathogens are mainly Gram-negative bacteria. The lungs are the most common infection site. Preoperative MELD score, preoperative sarcopenia and preoperative infection within 2 weeks are independent risk factors for infection within 90 days after liver transplantation. Regular monitoring of immune indicators CD4+T cells and CD8+T cells levels after transplantation is helpful to reduce the occurrence of post-transplantation infection.

To compare the performance differences between the multidisciplinary team (MDT) model and the conventional diagnostic and treatment model for lung cancer, and to explore a high-quality development pathway for optimizing lung cancer diagnostic and treatment resources. A retrospective analysis was conducted on electronic medical record data of lung cancer patients at Shanghai Chest Hospital from March 2025 to December 2025. Patients were divided into an MDT group and a conventional care group based on whether they were admitted to the integrated oncology ward. Statistical analyses were performed using the Mann-Whitney A total of 4, 758 patients with primary lung cancer were included, comprising 365 (7.7%) in the MDT group and 4, 393 (92.3%) in the conventional care group. After adjusting for confounding factors, the MDT model significantly reduced hospitalization frequency during the observation period by 48.8% ( The MDT model for lung cancer significantly reduces hospitalization frequency; however, its effect on cost per hospitalization is population-selective, with increased costs in early-stage (stage Ⅰ) patients and decreased costs in late-stage (stages Ⅱ and Ⅳ) patients. The implementation of the MDT model should adopt precise patient stratification management, prioritizing the optimal patient population to achieve the optimal allocation of medical resources.

ObjectiveTo evaluate the clinical efficacy and safety of acupuncture in treating severe Bell's palsy and to explore its potential mechanism by investigating the effect on serum levels of glial cell line-derived neurotrophic factor (GDNF) and nerve growth factor (NGF). MethodsA randomized, subject-blinded, sham-acupuncture controlled trial was conducted. A total of 130 patients with severe Bell's palsy were randomly allocated into a treatment group or a control group at a 1∶1 ratio. Both groups received conventional western medicine. In addition, the treatment group received acupuncture, while the control group received sham acupuncture, with each session lasting 30 minutes. The treatment course lasted 8 weeks for both groups, followed by a follow-up assessment at week 12. The primary outcome was the proportion of patients achieving House-Brackmann (H-B) grade Ⅱ or lower at week 8. Secondary outcomes included Sunnybrook facial grading system scores at week 0, 4, 8, and 12, the time to satisfactory recovery(the time required to achieve H-B grade≤Ⅱ), distribution of H-B grades and facial disability index (FDI) scores including the physical function subscale (FDIP) and social/well-being function subscale (FDIS) scores at week 0, 4, 8, and 12, and serum GDNF and NGF levels at week 0, 4, and 8. Adverse events and participants' self-assessments of treatment efficacy were also recorded. ResultsA total of 122 participants completed the study, including 62 in the treatment group and 60 in the control group. An intention-to-treat (ITT) analysis was performed, and missing data were handled using the last observation carried forward (LOCF) method. The proportion of patients achieving H-B grade ≤grade Ⅱ at week 8 was 78.5% (51/65) in the treatment group, significantly higher than 49.2% (32/65) in the control group (P<0.05). The Sunnybrook scores, FDIP and FDIS scores increased, while H-B grades decreased at week 4, 8, and 12 in both groups compared to week 0; moreover, improvements in all outcome measures were significantly greater in the treatment group than in the control group (P<0.05). The median time to satisfactory recovery was 6 weeks (95%CI: 5.697-6.303) in the treatment group, significantly shorter than 12 weeks (95%CI: 8.314-15.686) in the control group (P<0.05). Serum levels of GDNF and NGF were significantly higher in the treatment group at weeks 4 and 8 (P<0.05). No serious acupuncture-related adverse events occurred in either group. Adverse events were reported in 5 patients (7.69%) in the treatment group and 4 patients (6.15%) in the control group, with no statistically significant difference between groups (P>0.05). Patients' self-assessment of treatment efficacy after 8 weeks treatment was significantly better in the treatment group (P<0.05). ConclusionAcupuncture can effectively improve facial nerve function and shorten recovery time in patients with severe Bell's palsy, with a favorable safety profile. The therapeutic mechanism may be associated with the upregulation of serum GDNF and NGF levels.

OBJECTIVE To systematically evaluate the correlation between dynamic changes in inflammatory markers during treatment with epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) in non-small cell lung cancer (NSCLC) patients and therapeutic efficacy, with the aim of providing evidence-based support for clinical prognosis assessment and treatment strategy adjustment. METHODS Databases including PubMed, Embase, Cochrane Library, CNKI, Wanfang Data, and CBM were searched from the inception to July 20, 2025. Following literature screening, data extraction and quality assessment, descriptive analysis was conducted on the outcomes of included studies. RESULTS A total of eight studies were included to analyze the correlation of 6 inflammatory markers before and after treatment with EGFR-TKIs with therapeutic efficacy. The risk of bias assessment identified six high-quality studies and two moderate-quality studies. Among these studies, seven studies demonstrated that lower levels of neutrophil-to-lymphocyte ratio (NLR), derived neutrophil-to-lymphocyte ratio (dNLR), platelet-to-lymphocyte ratio (PLR), and monocyte-to-lymphocyte ratio (MLR), higher lymphocyte-to-monocyte ratio (LMR) before treatment, as well as decreased NLR and MLR and increased LMR after treatment were associated with longer median progression-free survival. Five studies indicated that lower levels of NLR, dNLR, PLR, and interleukin-6 (IL-6), higher LMR before treatment as well as decreased NLR and dNLR and increased LMR were associated with longer median overall survival. Three studies indicated that lower levels of IL-6 were associated with a higher objective response rate, while the association of these markers after treatment remained controversial; another study showed that an early decline in NLR, MLR, and PLR after treatment may be associated with objective response benefit. CONCLUSIONS Lower inflammatory levels during EGFR-TKIs therapy correlate with better therapeutic efficacy in NSCLC patients.

Objective To analyze the adverse reaction reports (ADRs) of drug-induced liver injury in recent ten years, explore the characteristics and related rules of drug-induced liver injury, and provide reference for clinical safe drug use. Methods ADRs in our hospital from 2011 to 2021 which belonged to drug-induced liver injuries were collected, and Pareto analysis was carried on. Results In 259 ADR reports, the most common type of drug-induced liver injury was hepatocellular injury (37.84%). The age of drug-induced liver injury was mainly over 46 years, totaling 195 (75.28%). Drugs were mainly distributed in cardiovascular system medicine (44.02%), anti-infective medicine (23.94%)and anti-tumor medicine (11.58%). Among the cardiovascular drugs, atorvastatin calcium 40mg and over 40mg were the highest proportion, with 53 cases (46.49%). The main anti-infectious drugs were cephalosporins (29.03%), carbapenem (19.35%), antifungal (17.74%)and quinolones (11.29%). Adverse reactions occurred within 6 days (69.88%), the duration of adverse reactions was 1-2 weeks (31.66%), and most patients were improved (47.88%) or cured (37.07%). Conclusion For middle-aged and elderly patients, when the application of cardiovascular system drugs, anti-infective drugs or anti-tumor drugs, it is necessary to monitor the liver function changes of patients for at least 6 days. If there are abnormalities, the drugs should be stopped or given treatment in time, to avoid the progress of drug-induced liver injury.

ObjectiveTo investigate the effect and mechanism of Yishen Tongluo prescription in protecting mice from oxidative stress injury in diabetic kidney disease (DKD) via the nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1)/NAD(P)H quinone oxidoreductase 1 (NQO1) signaling pathway. MethodsSpecific pathogen-free (SPF) male C57BL/6 mice were assigned into a control group (n=10) and a modeling group (n=50). The DKD model was established by intraperitoneal injection of streptozotocin. The mice in the modeling group were randomized into a model group, a semaglutide (40 μg·kg-1) group, and high-, medium-, and low-dose (18.2, 9.1, 4.55 g·kg-1, respectively) Yishen Tongluo prescription groups, with 10 mice in each group. The treatment lasted for 12 weeks. Blood glucose and 24-h urine protein levels were measured, and the kidney index (KI) was calculated. Serum levels of creatinine (SCr), blood urea nitrogen (BUN), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were assessed. The pathological changes in the renal tissue were evaluated by hematoxylin-eosin, periodic acid-Schiff, periodic acid-silver methenamine, and Masson’s trichrome staining. Enzyme-linked immunosorbent assay kits were used to measure the levels of β2-microglobulin (β2-MG), neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), liver fatty acid-binding protein (L-FABP), nitric oxide synthase (NOS), glutathione (GSH), total antioxidant capacity (T-AOC), and 8-hydroxy-2'-deoxyguanosine (8-OHdG). Immunohistochemical staining was performed to examine the expression of Kelch-like ECH-associated protein 1 (Keap1) and malondialdehyde (MDA). Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot were employed to determine the mRNA and protein levels, respectively, of factors in the Nrf2/HO-1/NQO1 signaling pathway. ResultsCompared with the control group, the DKD model group showed rises in blood glucose, 24-h urine protein, KI, SCr, BUN, and ALT levels, along with glomerular hypertrophy, renal tubular dilation, thickened basement membrane, mesangial expansion, and collagen deposition. Additionally, the model group showed elevated levels of β2-MG, NGAL, KIM-1, L-FABP, NOS, and 8-OHdG, lowered levels of GSH and T-AOC, up-regulated expression of MDA and Keap1, and down-regulated expression of Nrf2, HO-1, NQO1, and glutamate-cysteine ligase catalytic subunit (GCLC) (P<0.05). Compared with the model group, the semaglutide group and the medium- and high-dose Yishen Tongluo prescription groups showed reductions in blood glucose, 24-h urine protein, KI, SCr, BUN, and ALT levels, along with alleviated pathological injuries in the renal tissue. In addition, the three groups showed lowered levels of β2-MG, NGAL, KIM-1, L-FABP, NOS, and 8-OHdG, elevated levels of GSH and T-AOC, down-regulated expression of MDA and Keap1, and up-regulated expression of Nrf2, HO-1, NQO1, and GCLC (P<0.05). ConclusionYishen Tongluo prescription exerts renoprotective effects in the mouse model of DKD by modulating the Nrf2/HO-1/NQO1 signaling pathway, mitigating oxidative stress, and reducing renal tubular injuries.
