ObjectiveTo explore the possible mechanism of action of Lifei Xiaoji Pill （理肺消积丸， LXP） in the treatment of non small cell lung cancer based on the Warburg effect and the USP47/BACH1 pathway. MethodsFifty C57BL/6 mice were randomly divided into five groups， model group， LXP group， inhibitor group， LXP + inhibitor group， and cisplatin group， with 10 mice in each group. A lung cancer mouse model was established by subcutaneously injecting Lewis cells. On the next day， the model group mice were given 0.2 ml of saline by gavage daily， the LXP group given 240 mg/（kg·d） of LXP solution once a day by gavage， the inhibitor group intraperitoneally injected with P22077 at a dose of 10 mg/（kg·d） every day， the LXP + inhibitor group given both LXP by gavage and P22077 by intraperitoneal injection once a day， and the cisplatin group received 0.5 mg/（kg·d） cisplatin intraperitoneally every other day. All treatments lasted for 14 days. On the day after the last dose， tumor weight and volume were measured， tumor histopathology was examined by HE staining， apoptosis in tumor tissues was detected by TUNEL staining， and proliferation cell nuclear antigen （PCNA） protein levels were detected by immunohistochemistry. Warburg effect indicators， including glucose concentration， lactate content， and adenosine triphosphate （ATP） production in tumor tissues， were measured. Western Blot and qRT-PCR were used to detect the protein and mRNA expression levels of USP47， BACH1， hexokinase 2 （HK2）， and glyceraldehyde 3-phosphate dehydrogenase （GAPDH）. ResultsCompared with the model group， all drug intervention groups showed reduced tumor weight and volume， improved tumor pathology， decreased PCNA positive rate， increased apoptosis rate， and reduced expression levels of USP47， BACH1， and HK2 proteins and mRNA （P＜0.05 or P＜0.01）. Except for lactate content in the cisplatin group， the glucose concentration in tumor tissues of other drug intervention groups increased， while lactate content and ATP production decreased （P＜0.05 or P＜0.01）. Compared with the LXP group， the LXP + inhibitor group showed more significant improvements in these indicators （P＜0.05 or P＜0.01）. Compared with the cisplatin group， the LXP + inhibitor group had lower mRNA expression of HK2 and GAPDH， and lower protein levels of USP47 and HK2 （P＜0.05 or P＜0.01）. Compared with the inhibitor group， the cisplatin group had higher HK2 protein levels， while the LXP + inhibitor group showed lower mRNA expression of BACH1， HK2， and GAPDH （P＜0.05 or P＜0.01）. ConclusionLXP significantly inhibits tumor growth in lung cancer mice， and its mechanism of action may be related to inhibiting the Warburg effect via the USP47/BACH1 pathway.

Objective To explore the relationship between traditional Chinese medicine(TCM)constitution,functional connectivity(FC)of the dorsolateral prefrontal cortex(DLPFC),and fluid intelligence in university students to elucidate the mind-body relationship from a modern perspective of TCM.Methods From October 2023 to December 2023,a total of 96 college students of Jiangxi University of Chinese Medicine were included,and Classification and Identification of Constitution in Traditional Chinese Medicine:ZYYXH/T 157-2009,Raven's Advanced Progressive Matrices(RAPM)and resting-state functional near-infrared spectroscopy were used to evaluate TCM constitution,fluid intelligence,and FC of DLPFC.The differences in fluid intelligence between individuals with biased and balanced constitutions were compared using t-tests,and the associations among the TCM Constitution,RAPM score,and the FC between the left and right DLPFC were explored using partial correlation analysis.Results The tendency toward blood-stasis type and a dampness-heat type were positively correlated with the RAPM scores.College students with a tendency toward blood-stasis type exhibited significantly higher RAPM scores than those with a balanced constitution(P＜0.05).Additionally,significant negative correlations were observed between the tendencies toward blood-stasis and yin-deficiency types and the FC of the bilateral DLPFC.In contrast,a significant positive correlation was observed in individuals with balanced constitution tendencies.Conclusion The tendency toward blood-stasis type is associated with fluid intelligence levels and DLPFC functional activity in college students.This finding suggests that students with higher intelligence levels are more likely to exhibit blood-stasis type,highlighting the need for appropriate adjustments and interventions.

Objective:To analyze the etiological composition and clinical characteristics of infant hypertension，and provide reference for its diagnosis and treatment.Methods:This is a retrospective case-control study.Retrospective investigation and analysis were conducted on the clinical data of infants discharged from Beijing Children's Hospital Affiliated to Capital Medical University with a diagnosis of "hypertension" from June 1，2016 to September 30，2021，including clinical manifestations，auxiliary examinations，treatment plans，and prognosis.Results:A total of 74 eligible children were collected，including 42 male infants（56.8%）and 32 female infants（43.2%）.A total of 67 cases（90.5%）had clear secondary factors，including 35 cases of kidney disease（47.3%），12 cases of connective tissue disease（16.2%），and 9 cases of hematological tumor disease（12.2%）.At the beginning of the disease，cardiac ultrasound showed that 54 cases（73.0%）had ventricular wall thickening，including mild thickening in 31 cases（57.4%），moderate thickening in 11 cases（20.3%），and severe thickening in 12 cases（22.2%）.After grouping by etiology，the incidence of proteinuria and severe hypertension in the renal hypertension group，as well as those receiving multiple antihypertensive drugs，was significantly higher than that in the non-renal hypertension group（ χ 2=28.493， P<0.001； χ 2=17.283， P<0.001； χ 2=17.358， P<0.001）；Renal disease was risk factor for severe hypertension in infants according to univariate and multivariate logistic regression analysis respectively（ OR=11.176，95% CI：2.882~43.339， P<0.001； OR=11.669，95% CI：2.921~46.624， P<0.001）.Thirty-one children had follow-up records for 6 months or more，and 13（41.9%）still required antihypertensive treatment，of whom 26（83.9%）were no longer recorded as having elevated blood pressure. Conclusion:Infant hypertension is mainly secondary，with a high proportion of renal factors and predisposition to severe hypertension，which requires multiple antihypertensive drugs for control.Active antihypertensive treatment and removal of secondary factors during the acute phase are helpful for controlling hypertension in infants，but further research is needed on treatment options and long-term prognosis.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Objective:To summarize the clinical characteristics of invasive Group A Streptococcus (GAS) infection in children and to provide reference for its clinical treatment and diagnosis. Methods:The medical records of inpatients whose sterile body fluids tested positive for GAS in Beijing Children′s Hospital from February 2013 to June 2024 were reviewed in this case series study.The clinical information of the patients was collected and summarized as a case report.Non-normally distributed measurement data were represented by the median ( M), and count data were represented by cases (%). Results:There were 42 cases of invasive GAS infection, with a median age of 6 years and 3 months (range: 14 days to 13 years and 7 months).Twenty-seven patients (64.3%) developed this disease in winter.In terms of susceptibility factors, there were 4 cases of trauma, 2 cases of influenza A, 1 case of neuroblastoma chemotherapy myelosuppression, 1 case of acute lymphoblastic leukemia chemotherapy myelosuppression, 1 case of varicella, and 1 case of scald among these 42 patients, there are no other obvious susceptibility factors.The types of specimens in which GAS was detected included 23 blood specimens, 9 pleural effusions, 9 sterile-site pus specimens, and 5 cerebrospinal fluids.GAS was detected in 4 children from two types of specimens simultaneously.The methods for detecting GAS included bacterial culture in 35 cases and next-generation sequencing in 9 cases.Two children tested positive for GAS by both methods.According to clinical diagnoses, there were 17 cases of pneumonia, 13 cases of streptococcus toxic shock syndrome, 10 cases of purulent meningitis, 6 cases of purulent osteomyelitis, 6 cases of purulent arthritis, 5 cases of cellulitis, 3 cases of necrotizing fasciitis, 2 cases of infectious myositis, and 2 cases of cervical abscess.Two or more clinical manifestations were detected in 26 patients.Drug sensitivity reports were available for 26 cases.All strains were sensitive to Penicillin, Vancomycin, Linezolid, Ceftriaxone and Cefepime.All except 2 were resistant to Clindamycin, and all were resistant to Erythromycin.All 42 cases were treated with intravenous antibiotics, and 21 of them also received human immunoglobulin.Three of the patients died and 39 were discharged from hospital. Conclusions:Pediatric invasive GAS infection occurs mainly in winter and manifests as pneumonia, purulent meningitis, purulent osteomyelitis, and purulent arthritis.The strains are sensitive to β-lactam antibiotics, Vancomycin and Linezolid, and most are resistant to Clindamycin and Erythromycin.

ObjectiveTo analyze the development status and quality of clinical practice guidelines for the treatment of dominant diseases with Chinese patent medicines （CPMs）. MethodsDatabases were searched from Jan. 2019 to Dec.2023 to collect the published clinical practice guidelines of CPMs for the treatment of dominant diseases. The information about the title， the participants， clinical problems， outcomes， evidence grade， recommendations， and recommendation strength in the included clinical practice guidelines were collected， for which the development status was analyzed， and the quality was evaluated with the Scientific， Transparent and Applicable Rankings （STAR） tool for clinical practice guidelines. ResultsTotally， 34 guidelines were included， involving 273 kinds of CPMs. One to ten （with the medium five） clinical problems were proposed from 29 clinical practice guidelines respectively. All the guidelines divided the evidence into four grades according to Grade of Recommendation Assessment， Deve-lopement an Evaluation. And 28 guidelines had five levels of recommendation strength. A total of 344 recommendations were extracted， including 86 strong-recommendations， 191 weak-recommendations （including 36 weak recommendations only based on expert consensus） and 67 recommendations with unclear recommendation strength. All guidelines had high scores in the three areas of “clinical questions （94.20%）”， “evidence （91.45%）” and “recommendations （89.06%）”， while the scores in the three areas of “registry （22.06%）”， “protocol （19.00%）” and “accessibility （31.51%）” were low. The STAR recommended stars of 8 guidelines were 5.0~4.0 stars， while that of 18 guidelines were 3.5~2.5 stars， and 8 guidelines were 2.0~1.0 stars. The three guidelines with the highest recommended stars were depressive disorder， community-acquired pneumonia， and influenza in adult. ConclusionThere is a certain gap in the quality of the published clinical practice guidelines of CPMs， and the quality of the guidelines could be further improved in registry， protocols， funds， and accessibility.

Objective:To investigate the value of 18F-FDG PET/CT imaging in the diagnosis of suspected autoimmune encephalitis (AE) in children with epilepsy and negative MRI. Methods:From May 2019 to August 2022, 94 suspected AE children (49 males, 45 females; age 1-15 years) with epilepsy and negative MRI who underwent brain 18F-FDG PET/CT imaging at Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine were retrospectively analyzed. All patients were divided into AE and non-AE groups based on clinical final diagnosis. The effectiveness of visual diagnosis was evaluated. The cortical lesion extent score (S), and SUV max, SUV mean and minimum of SUV (SUV min) of cortical lesions (L), basal ganglia (B) and thalamus (T) were measured and SUV ratios (SUVR) of L/B or L/T were obtained. Independent-sample t test or Mann-Whitney U test was used to analyze data. Binary logistic regression analysis was used to screen the diagnostic factors of AE, and a diagnostic model was established. The diagnostic efficiency was evaluated by ROC curve analysis and Delong test. Results:There were 53 cases in AE group and 41 cases in non-AE group. Based on visual analysis, the sensitivity, specificity and accuracy of 18F-FDG PET/CT for AE were 100%(53/53), 43.9%(18/41) and 75.5%(71/94), respectively. Differences of LSUV max, LSUV mean, LSUV min, L/BSUVR max, L/BSUVR mean, L/BSUVR min, L/TSUVR max, L/TSUVR mean, L/TSUVR min and S between AE and non-AE groups were statistically significant ( z=-6.74, t values: from -8.51 to -3.97, all P<0.001). ROC curve analysis showed that the AUC of L/BSUVR max was the highest (0.914) among visual analysis and semi-quantitative parameters. Logistic regression analysis showed that S (odds ratio ( OR)=11.40, 95% CI: 2.18-59.52, P=0.004), L/BSUVR max( OR=13.19, 95% CI: 2.11-82.51, P=0.006) and L/TSUVR max( OR=9.66, 95% CI: 1.57-59.55, P=0.015) were independent diagnostic factors for AE. Regression model was established: P=1/(1+ e - x), x=2.433×S+ 2.580×L/BSUVR max+ 2.267×L/TSUVR max-3.802. The AUC of this model was 0.948, with the sensitivity, specificity and accuracy of 98.1%(52/53), 90.2%(37/41) and 94.7%(89/94), respectively. The diagnostic efficacy of the optimized scoring system was consistent with the pre-optimization model, and were both superior to L/BSUVR max(both z=2.01, both P=0.040). Conclusion:The diagnostic model and scoring system based on the semi-quantitative analysis of 18F-FDG PET/CT have better diagnostic efficacy for AE and are superior to semi-quantitative parameters alone.
