ObjectiveTo observe the clinical effectiveness and safety of Qingfei Shenshi Decoction (清肺渗湿汤) combined with western medicine for patients with bronchial asthma of heat wheezing syndrome, and to explore its potential mechanism of action. MethodsEighty-six participants with bronchial asthma of heat wheezing syndrome were randomly divided into treatment group and control group, each group with 43 participants. The control group received conventional western medicine, and the treatment group was additionally administered Qingfei Shenshi Decoction orally on the basis of the control group, 1 dose per day. Both groups were treated for 14 days. The primary outcome measure was clinical effectiveness; secondary outcome measures included traditional Chinese medicine (TCM) syndrome score, asthma control test (ACT) score, pulmonary function indices such as forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), peak expiratory flow (PEF), serum inflammatory factor levels including interleukin-4 (IL-4), tumour necrosis factor-α (TNF-α), and high-sensitivity C-reactive protein (hs-CRP), and immune function indices including CD3+, CD4+, CD8+, CD4+/CD8+. All outcome measures were evaluated before and after treatment. Vital signs were monitored, and electrocardiography, blood routine, urine routine, liver function, and renal function tests were performed before and after treatment. Adverse events and reactions during the study were recorded. ResultsA total of 80 patients completed the trial with 40 in each group. The total clinical effective rate of the treatment group was 97.5% (39/40), which was significantly higher than that of the control group (85.0%, 34/40, P<0.05). After treatment, both groups showed decreased TCM syndrome scores, IL-4, TNF-α, hs-CRP, and CD8+ levels, as well as increased ACT scores, CD3+, CD4+, CD4+/CD8+, FEV1, FVC, and PEF levels (P<0.05 or P<0.01). Moreover, the improvements in these indices were more significant in the treatment group than in the control group (P<0.05 or P<0.01). No significant abnormalities in safety indicators were observed in either group, and no adverse events or reactions occurred. ConclusionQingfei Shenshi Decoction combined with conventional western medicine for patients with bronchial asthma of heat wheezing syndrome can effectively improve the clinical symptoms, pulmonary function, and clinical effectiveness, with good safety. Its mechanism may be related to reducing inflammatory factor levels and regulating T lymphocyte subsets to improve immune function.

OBJECTIVE:
To observe the effects of Tongdu Tiaoshen acupuncture (for unblocking the obstruction in the governor vessel and regulating the spirit) on depression-like behavior and the hippocampal Endophilin A1/reactive oxygen species (ROS) pathway in the chronic unpredictable mild stress (CUMS) model rats, and explore the mechanism of this therapy for depression.
METHODS:
Forty-eight male SD rats of SPF grade were randomly divided into a normal group (n=12) and a modeling group (n=36). In the modeling group, CUMS was performed to establish depression model. The successfully-modeled rats were randomized into a model group, a Tongdu Tiaoshen acupuncture group (referred to as the acupuncture group), and a fluoxetine group, with 12 rats in each group. In the acupuncture group, "Baihui" (GV20), "Shenting" (GV24), "Shuigou" (GV26) and "Dazhui" (GV14) were stimulated with acupuncture. This intervention measure was delivered once a day, continuously for 6 days; it was discontinued on day 7 and was completed in 28 days. In the fluoxetine group, intragastric administration was done with fluoxetine solution (2.1 mg/kg), once a day, and for 28 consecutive days. Before and after modeling, and after intervention completion, the body mass, sucrose preference rate and the total distance of movement and the boxes of horizontal crossing in the open field experiment were observed in each group. After intervention, using HE staining, the hippocampal neuron morphology was observed; using Nissl staining, the hippocampal Nissl body number was counted. The hippocampal mitochondria was observed under transmission electron microscopy. The average fluorescence intensity of ROS in hippocampal was determined using flow cytometry. With Western blot method, the protein expression of Endophilin A1, growth associated protein 43 (GAP-43), and brain-derived neurotrophic factor (BDNF) in hippocampal was detected; and with RT-qPCR method, the mRNA expression of Endophilin A1, GAP-43, and BDNF was recorded. Using the immunofluorescence, the average fluorescence intensity of Endophilin A1, GAP-43, and BDNF in hippocampal tissue was determined.
RESULTS:
Compared with the normal group, in the model group, the body mass, sucrose preference rate, and the total distance of movement and the boxes of horizontal crossing in the open field experiment decreased (P<0.01); the hippocampal neuronal structure was unclear, the matrix was relatively loose, and the number of Nissl body decreased (P<0.01); mitochondrial structure was disarranged, the outer membrane was ruptured, mitochondrial cristae was irregular or missed; the average fluorescence intensity of ROS in hippocampal tissue, the protein and mRNA expression and the average fluorescence intensity of Endophilin A1 in hippocampal tissue increased (P<0.01), while the protein and mRNA expression of GAP-43 and BDNF and its average fluorescence intensity decreased (P<0.01). Compared with the model group, the acupuncture group and the fluoxetine group showed the increase in body mass, sucrose preference rate, the total distance of movement and the boxes of horizontal crossing in the open field experiment (P<0.05, P<0.01); the hippocampal neuronal structure became relatively clear, the matrix was relatively dense, and the number of Nissl body was elevated (P<0.01); mitochondrial structure got normal and disarranged slightly, the average fluorescence intensity of ROS in hippocampal tissue, the protein and mRNA expression and the average fluorescence intensity of Endophilin A1 in hippocampal tissue were reduced (P<0.01), while the protein and mRNA expression of GAP-43 and BDNF and the average fluorescence intensity rose (P<0.01, P<0.05). Compared with the fluoxetine group, the acupuncture group presented the increase in the average fluorescence intensity of ROS, the protein expression and the average fluorescence intensity of Endophilin A1, the protein expression of GAP-43 and the mRNA expression of BDNF (P<0.01, P<0.05), and the decrease of the protein expression and the average fluorescence intensity of BDNF, the mRNA expression of Endophilin A1, and the average fluorescence intensity of GAP-43 (P<0.01, P<0.05).
CONCLUSION
Tongdu tiaoshen acupuncture alleviates depression-like behaviors in CUMS model rats and protects hippocampal neurons, which may be related to suppressing Endophilin A1/ROS signaling pathway and attenuating oxidative stress reactions.

Objective:To evaluate the efficacy of ultrasound-guided subcostal quadratus lumborum block combined with general anesthesia in laparoscopic bariatric surgery.Methods:In this prospective randomized controlled study, 80 American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱpatients, aged 18-40 yr, with a body mass index of 30-45 kg/m 2, of cardiac function classification Ⅰ or Ⅱ, who underwent laparoscopic bariatric surgery at the First Affiliated Hospital of Nanjing Medical University from February 2023 to May 2023, were selected and divided into 2 groups ( n=40 each) using a table of random numbers: general anesthesia group (GA group) and subcostal quadratus lumborum block combined with general anesthesia group (SQB+ GA group). Both groups received combined intravenous-inhalational anesthesia. Patients in SQB+ GA group underwent bilateral ultrasound-guided subcostal quadratus lumborum block with 20 ml of 0.375% ropivacaine before anesthesia induction. Oxycodone was administered for analgesia during the post-anesthesia care unit (PACU) stay. Patient-controlled intravenous analgesia with sufentanil and granisetron was used after returning to the ward. When the visual analog scale score >4 within 24 h after surgery, flurbiprofen axetil 50 mg was intravenously given as rescue analgesic. The intraoperative consumption of remifentanil and use of vasoactive drugs were recorded. The effective pressing times of patient-controlled analgesia and requirement for rescue analgesia were recorded. The tracheal extubation time, PACU stay time, use of oxycodone during PACU stay, and occurrence of hypoxemia after tracheal extubation and occurrence of adverse reactions within 24 h after surgery was also recorded. Arterial blood gas analysis was performed at discharge from PACU. Results:Compared with GA group, the intraoperative consumption of remifentanil was significantly reduced, the usage rate of oxycodone, effective pressing times of patient-controlled analgesia and rate of rescue analgesia were significantly decreased, the PaO 2 and PaCO 2 at discharge from PACU were decreased, the tracheal extubation time and PACU stay time were shortened, and the incidence of hypoxemia after tracheal extubation and postoperative nausea and vomiting was decreased in SQB+ GA group ( P<0.05). Conclusions:Compared with general anesthesia alone, ultrasound-guided subcostal quadratus lumborum block combined with general anesthesia can reduce the intraoperative consumption of opioids, alleviate postoperative pain, and decrease the occurrence of postoperative adverse reactions when used in laparoscopic bariatric surgery.

Objective:To investigate the effect of miR-1-3p on mitophagy in human esophageal squamous cell carcinoma (ESCC) cells and the related mechanisms.Methods:The differentially expressed miRNAs in ESCC were screened using the GEO database. Real-time quantitative polymerase chain reaction (RT-qPCR) was used to measure miR-1-3p expression in normal esophageal epithelial cells (HET-1A) and ESCC cell lines (TE1, KYSE30, KYSE150, KYSE410, Eca109). Bioinformatics tools were utilized to predict target genes of miR-1-3p, subcellular localization was confirmed by fluorescence in situ hybridization. The targeting relationship between miR-1-3p and SLC7A11 was validated using dual-luciferase reporter assay. Cell proliferation and apoptosis were detected by CCK8 assay and flow cytometry, respectively. Furthermore, experimental validation demonstrated that overexpression of SLC7A11 rescued the presence of the miR-1-3p/SLC7A11 axis. Confocal microscopy was used to detect changes in mitochondrial autophagic lysosomes, while transmission electron microscopy was employed to observe mitophagy and morphological alterations. Western blot was conducted to evaluate the expression of autophagy-related proteins LC3 and P62. Flow cytometry was used to measure mitochondrial membrane potential and reactive oxygen species (ROS). Immunohistochemistry was applied to assess SLC7A11 expression in 133 ESCC patient tissues and 115 normal esophageal epithelial tissues. The correlation between SLC7A11 expression level and clinicopathological features was analyzed. Survival analysis was performed using the Kaplan-Meier method, and Cox proportional hazard regression models were used for multivariate analysis.Results:The expression of miR-1-3p in ESCC cells was significantly lower than that in HET-1A cells ( P<0.05). SLC7A11 was a target gene of miR-1-3p. Transfection of miR-1-3p mimic inhibited the proliferation of ESCC cells. CCK-8 assay results showed that the proliferative capacity of KYSE30 and KYSE410 cells in the miR-1-3p mimic group (absorbance values: 2.88±0.24 and 2.88±0.18, respectively) was significantly lower than that in the miRNA mimic negative control (NC) group (3.94±0.27, P<0.001; 4.20±0.21, P<0.001). Meanwhile, the proliferative capacity of KYSE30 and KYSE410 cells in the miR-1-3p mimic+SLC7A11-overexpression (OE) group (absorbance values: 3.57±0.15 and 3.60±0.13, respectively) was significantly higher than that in the miR-1-3p mimic +empty vector (EV) group (2.54±0.10, P<0.001, 2.36±0.16, P<0.001). Additionally, transfection of miR-1-3p mimic promoted apoptosis. Flow cytometry results demonstrated that the apoptosis rates of KYSE30 and KYSE410 cells in the miR-1-3p mimic group [(9.22±0.05)% and (6.55±0.37)%, respectively] were significantly higher than those in the miRNA mimic NC group [(0.81±0.17)%, P<0.001); (1.04±0.12)%, P<0.001]. Conversely, the apoptosis rates of KYSE30 and KYSE410 cells in the miR-1-3p mimic + SLC7A11-OE group [(0.73±0.04)% and (1.19±0.05)%, respectively] were significantly lower than those in the miR-1-3p mimic+EV group [(9.83±0.41)%, P<0.001); (6.09±0.17)%, P<0.00)]. MiR-1-3p mimic downregulated SLC7A11 protein expression and the LC3Ⅱ/LC3I ratio ( P<0.05), upregulated P62 protein expression ( P<0.05), this phenomenon can be rescued by overexpressing SLC7A11 ( P<0.05). Additionally, miR-1-3p mimic increased ROS levels and decreased mitochondrial membrane potential (JC-1 aggregate/monomer ratio), this phenomenon can be rescued by overexpressing SLC7A11 ( P<0.05). SLC7A11 expression was higher in ESCC tissues compared to normal esophageal epithelial tissues ( P<0.001), and SLC7A11 serves as an independent prognostic factor in ESCC ( HR=2.15, 95% CI: 1.27-3.65, P=0.004). Conclusion:miR-1-3p inhibits mitophagy in esophageal squamous cell carcinoma by targeting SLC7A11.

Objective:To adapt the English version of exteroceptive body awareness questionnaire (EBA-q) into Chinese, and evaluate its reliability and validity in college students.Methods:English version EBA-q was translated and culturally adapted into Chinese, and the tests were administered from October to December 2024, with valid data collected from 1 071 college students. Item analysis, exploratory factor analysis, confirmatory factor analysis, criterion-related validity analysis, and reliability analysis were conducted by SPSS 23.0 and Mplus 8.3 softwares.Results:(1) The Chinese version of EBA-q contained seventeen items across five factors: visual awareness, tactile awareness, body coordination, awareness of body changes and awareness of clothing fit. The five-factor measurement model fitted the data well ( χ2/ df=2.24, CFI=0.95, TLI=0.94, RMSEA=0.05, SRMR=0.06). (2) The EBA-q scores were positively correlated with the scores of noticing, body listening, public self-consciousness, and private self-consciousness ( r=0.46, 0.36, 0.09, 0.25, all P<0.01). (3)The Cronbach's α coefficient, split-half reliability and test-retest reliability of the Chinese version of EBA-q were 0.79, 0.85 and 0.77, respectively(all P<0.01). Conclusion:The Chinese version of the EBA-q has demonstrated good reliability in assessing external body awareness among college students, but its validity requires further verification.

BACKGROUND:
This study aimed to investigate programmed death-ligand 1 tumor proportion score in predicting the safety and efficacy of PD-1/PD-L1 antibody-based therapy in treating patients with advanced non-small cell lung cancer (NSCLC) in a real-world setting.
METHODS:
This retrospective, multicenter, observational study enrolled adult patients who received PD-1/PD-L1 antibody-based therapy in China and met the following criteria: (1) had pathologically confirmed, unresectable stage III-IV NSCLC; (2) had a baseline PD-L1 tumor proportion score (TPS); and (3) had confirmed efficacy evaluation results after PD-1/PD-L1 treatment. Logistic regression, Kaplan-Meier analysis, and Cox regression were used to assess the progression-free survival (PFS), overall survival (OS), and immune-related adverse events (irAEs) as appropriate.
RESULTS:
A total of 409 patients, 65.0% ( n = 266) with a positive PD-L1 TPS (≥1%) and 32.8% ( n = 134) with PD-L1 TPS ≥50%, were included in this study. Cox regression confirmed that patients with a PD-L1 TPS ≥1% had significantly improved PFS (hazard ratio [HR] 0.747, 95% confidence interval [CI] 0.573-0.975, P = 0.032). A total of 160 (39.1%) patients experienced 206 irAEs, and 27 (6.6%) patients experienced 31 grade 3-5 irAEs. The organs most frequently associated with irAEs were the skin (52/409, 12.7%), thyroid (40/409, 9.8%), and lung (34/409, 8.3%). Multivariate logistic regression revealed that a PD-L1 TPS ≥1% (odds ratio [OR] 1.713, 95% CI 1.054-2.784, P = 0.030) was an independent risk factor for irAEs. Other risk factors for irAEs included pretreatment absolute lymphocyte count >2.5 × 10 9 /L (OR 3.772, 95% CI 1.377-10.329, P = 0.010) and pretreatment absolute eosinophil count >0.2 × 10 9 /L (OR 2.006, 95% CI 1.219-3.302, P = 0.006). Moreover, patients who developed irAEs demonstrated improved PFS (13.7 months vs. 8.4 months, P <0.001) and OS (28.0 months vs. 18.0 months, P = 0.007) compared with patients without irAEs.
CONCLUSIONS
A positive PD-L1 TPS (≥1%) was associated with improved PFS and an increased risk of irAEs in a real-world setting. The onset of irAEs was associated with improved PFS and OS in patients with advanced NSCLC receiving PD-1/PD-L1-based therapy.

Venous system diseases mainly include varicose veins and venous malformations of lower limbs and the genital system. Most of them are chronic diseases that cause serious clinical symptoms to patients and affect their health and quality of life. Sclerotherapy has become the first-line therapy for venous system diseases. However, there are problems such as incomplete fibrosis and vascular recanalization after sclerotherapy, and improper operation will cause serious adverse consequences. Therefore, exploring a safe and effective sclerotherapy strategy is essential for developing clinically successful sclerotherapy. To solve the above problems, we proposed a new sclerotherapy strategy with a dual mechanism of "vascular damage and plasmin (PLA) system inhibition." We intended to construct a novel cationic surfactant (AEOx-TA) by reacting tranexamic acid (TA), a parent structure, with fatty alcohol polyoxyethylene ether (AEOx) by ester bonds. AEOx-TA could damage vascular endothelium and initiate a coagulation cascade effect to induce thrombus. Furthermore, AEOx-TA could be degraded by esterase and release the parent drug, TA, which could inhibit the PLA system to inhibit the degradation of thrombus and extracellular matrix and promote the process of vascular fibrosis. In addition, such surfactant-based sclerosants have foam-forming properties, and they can be blended with polyvinyl alcohol (PVA) to prepare a highly stable foam formulation (AEOx-TA/P), which can achieve a precise drug delivery and prolonged drug retention time, thereby improving drug efficacy and reducing the risk of ectopic embolism. Overall, the novel cationic surfactant AEOx-TA provides a new avenue to resolve the bottleneck: surfactant sclerosants' efficiency is relatively low in the current sclerotherapy.

Natural products (NPs) have long held a significant position in various fields such as medicine, food, agriculture, and materials. The chemical space covered by NPs is extensive but often underexplored. Therefore, high-throughput and efficient methodologies for the annotation and discovery of NPs are desired to address the complexity and diversity of NP-based systems. Mass spectrometry (MS) has emerged as a powerful platform for the annotation and discovery of NPs. MS databases provide vital support for the structural characterization of NPs by integrating extensive mass spectral data and sample information. Additionally, the released annotation methodologies, based on a variety of informatics tools, continuously improve the ability to annotate the structure and properties of compounds. This review examines the current mainstream databases and annotation methodologies, focusing on their advantages and limitations. Prospects for future technological advancements are then discussed in terms of novel applications and research objectives. Through a systematic overview, this review aims to provide valuable insights and a reference for MS-based NPs annotation, thereby promoting the discovery of novel natural entities.
