ObjectiveThis study aimed to investigate whether Bushen Tongluo prescription inhibits macrophage polarization by regulating the Wnt3a/β-catenin signaling pathway， thereby reducing epithelial-mesenchymal transition and excessive extracellular matrix deposition， in order to elucidate the anti-pulmonary fibrosis mechanisms of Bushen Tongluo prescription and provide a new theoretical basis for the clinical treatment of pulmonary fibrosis. MethodsFifty male Sprague-Dawley （SD） rats were randomly divided into a blank group， model group， pirfenidone group， and high- and low-dose Bushen Tongluo prescription groups. Except for the blank group， the pulmonary fibrosis model was established by intratracheal instillation of bleomycin. Intervention was initiated on day 28 after modeling. The high- and low-dose Bushen Tongluo prescription groups were administered Bushen Tongluo prescription at doses of 30.88， 15.44 g·kg^-1， respectively， by intragastric gavage. The pirfenidone group was administered pirfenidone capsules at 110 mg·kg^-1 by intragastric gavage. The blank and model groups were given an equal volume of normal saline by gavage， once daily for 90 days. After treatment， the level of transforming growth factor-β₁ （TGF-β₁） in bronchoalveolar lavage fluid （BALF） was detected by enzyme-linked immunosorbent assay （ELISA）. Morphological changes in lung tissue and the collagen volume fraction were compared. The protein distribution and expression of E-cadherin， cytokeratin 19， α-smooth muscle actin （α-SMA）， vimentin， collagen type Ⅰ （Col Ⅰ）， and collagen type Ⅲ （Col Ⅲ） in lung tissue were detected by immunohistochemistry. The protein distribution and expression of CD68， arginase-1 （Arg-1）， inducible nitric oxide synthase （iNOS）， Wnt3a， and β-catenin in lung tissue were detected by immunofluorescence. The protein expression of Wnt3a and β-catenin in lung tissue was detected by Western blot， and the mRNA expression of Wnt3a and β-catenin was detected by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. ResultsCompared with the blank group， a large number of inflammatory cells infiltrated the airway walls， alveolar spaces， and interstitial tissue in the model group， with obvious fibrous tissue hyperplasia. The level of TGF-β₁ in BALF was significantly increased. The protein expression of E-cadherin and cytokeratin 19 in lung tissue was decreased， whereas the protein expression of α-SMA， Vimentin， Wnt3a， β-catenin， Col Ⅰ， and Col Ⅲ was increased. The fluorescence-positive area ratios of CD68， Arg-1， iNOS， Wnt3a， and β-catenin in lung tissue were increased. The protein and mRNA expression levels of Wnt3a and β-catenin in lung tissue were significantly increased （P<0.01）. Compared with the model group， all treatment groups showed varying degrees of improvement in inflammatory cell infiltration and fibrous tissue hyperplasia in the airway walls， alveolar spaces， and interstitial tissue， decreased TGF-β₁ levels in BALF， increased protein expression of E-cadherin and cytokeratin 19 in lung tissue， decreased protein expression of α-SMA， Vimentin， Col Ⅰ， and Col Ⅲ， decreased fluorescence-positive area ratios of CD68， Arg-1， iNOS， Wnt3a， and β-catenin in lung tissue， and decreased protein and mRNA expression levels of Wnt3a and β-catenin in lung tissue （P<0.05， P<0.01）. ConclusionBushen Tongluo prescription can improve bleomycin-induced pulmonary fibrosis in rats by inhibiting epithelial-mesenchymal transition and reducing excessive extracellular matrix deposition. The mechanism may be related to inhibition of the Wnt3a/β-catenin signaling pathway and the macrophage polarization mediated by this pathway.

Integrin α _v β ₃ is overexpressed in various tumor cells and angiogenesis. To date, no drug has been proven to target it for therapy. A first-in-human study was designed to investigate the safety, pharmacokinetics, and dosimetry of ¹⁷⁷Lu-AB-3PRGD2, a novel integrin α _v β ₃-targeting radionuclide drug with an albumin-binding motif to optimize the pharmacokinetics. Ten patients (3 men, 7 women; aged 45 ± 16 years) with integrin α _v β ₃-avid tumors were recruited to accept ¹⁷⁷Lu-AB-3PRGD2 injection in a dosage of 1.57 ± 0.08 GBq (42.32 ± 2.11 mCi), followed by serial scans to obtain its dynamic distribution in the body. Safety tests were performed before and every 2 weeks after the treatment for 6-8 weeks. No adverse event over grade 3 was observed. ¹⁷⁷Lu-AB-3PRGD2 was excreted mainly through the urinary system, with intense radioactivity in the kidneys and bladder. Moderate distribution was found in the liver, spleen, and intestines. The estimated blood half-life was 2.85 ± 2.17 h. The whole-body effective dose was 0.251 ± 0.047 mSv/MBq. The absorbed doses were 0.157 ± 0.032 mGy/MBq in red bone marrow and 0.684 ± 0.132 mGy/MBq in kidneys. This first-in-human study of ¹⁷⁷Lu-AB-3PRGD2 treatment indicates its promising potential for targeted radionuclide therapy of integrin α _v β ₃-avid tumors. It merits further studies in more patients with escalating doses and multiple treatment courses.

This study sought to evaluate the efficacy and safety of venetoclax (Ven) in combination with tyrosine kinase inhibitors (TKI) and reduced-dose chemotherapy for the treatment of patients with minimal residual disease (MRD) -positive and relapsed/refractory (R/R) Ph-positive acute lymphoblastic leukemia (Ph + ALL). A retrospective analysis was conducted on the clinical data of 13 patients with MRD-positive and relapsed Ph + ALL admitted between July 2015 and February 2024 at the Affiliated Cancer Hospital of Zhengzhou University. The cohort included seven males and six females, with a median age of 50 years (range: 37-71 years). Reinduction therapy consisted of Ven and TKI administration combined with reduced-dose chemotherapy. Among the 13 patients, 10 were MRD-positive, and three had R/R disease. Of the MRD-positive group, nine (90%) achieved complete molecular response (CMR), with a median time to response of 47 days (range: 30-80) ; one patient did not respond. Among the three patients who had R/R, two (66.6%) achieved complete remission, while one patient was nonresponsive. The median overall survival (OS) and relapse-free survival (RFS) time for the entire cohort were 21.5 months and 7 months, respectively. In patients who achieved CMR, the median OS and RFS time were 35 months and 34 months, respectively. Grade ≥3 hematologic adverse events occurred in five patients (38.4%) ; however, hematopoietic function recovered in all cases, and no grade ≥3 infections or organ-related adverse reactions were observed. These findings suggest that Ven combined with TKI and reduced-dose chemotherapy may be an effective and tolerable therapeutic strategy for MRD-positive and R/R Ph + ALL, particularly in significantly improving MRD clearance rates.

Pulmonary sarcoidosis is an immune system disease with an unclear etiology. Guided by the yang-reinforcing method， it is believed that the fundamental pathogenesis of pulmonary sarcoidosis lies in the disharmony between water and fire and the reckless movement of the ministerial fire. The failure of the spleen and stomach to maintain warmth， leading to the production of phlegm and blood stasis， is an important pathogenesis. The invasion of external pathogenic toxins， deeply penetrating into the interior， is considered a triggering factor for the disease. The treatment focuses on supplementing the yang， consolidating the kidney， drawing fire back to its source， warming the yang， benefiting the kidney， and nourishing the spleen to generate metal. It also emphasizes unblocking the yang， transforming turbidity， and eliminating phlegm and blood stasis.

Spinal surgical site infection (SSI), especially deep SSI after internal fixation is difficult in treatment, with long course of disease and poor prognosis. At present, there are many controversies in the diagnosis and treatment of spinal SSI, with unsatisfactory overall efficacy of its diagnosis and treatment. Besides, no diagnosis and treatment guideline based on evidence-based medicine has been in existence. To this end, the Spinal Infection Group of the Orthopedic Branch of the Chinese Medical Doctor Association and the Spinal Infection Group of the Spinal Surgery Branch of the Chinese Rehabilitation Medicine Association jointly organized relevant experts to formulate Evidence-based clinical guideline for the diagnosis and treatment of surgical site infection in spinal trauma ( version 2024) based on an evidence-based approach. A total of 10 recommendations were proposed on the diagnosis and treatment of spinal SSI, so as to provide a clinical reference for the diagnosis and treatment of spinal SSI.

Objective To observe the effect of preoperative enteral nutritional support combined with modified Ivor-Lewis surgery for esophageal cancer on lung function and mRNA expression of GATA-binding protein 3(GATA3)and forkhead protein P3(Foxp3)in peripheral blood.Methods Sixty esophageal cancer patients who underwent modified Ivor-Lewis surgery in our hospital from January 2022 to October 2023 were selected and divided into two groups by simple random method.The control group was given conventional diet before operation,and the observation group was given enteral nutrition support before operation.The two groups were compared in terms of nutritional support.Results Both groups showed significantly decreases in one-second exertion expiratory volume/exertion lung volume(FEV1/FVC)(P<0.05),FVC(P<0.05),FEV1(P<0.05)and the levels of peripheral blood GATA3(P<0.05),Foxp3 mRNA(P<0.05)expression compared with those at admission(P<0.05),but no significant differences in pulmonary function(P>0.05),peripheral blood GATA3(P>0.05),and Foxp3 mRNA(P>0.05)expression between them at 1 week postoperatively.Both groups exhibited significantly lower levels of albumin,prealbumin,haemoglobin,transferrin,PNI and body mass and body mass index at admis-sion as compared to those at one week after surgery(P<0.05).The observation group showed significantly higher levels of albumin,prealbumin,haemoglobin,transferrin,and PNI at 1 week postoperatively(P<0.05),but no significant differences in ventilation time,defecation time,drain retention time,hospitalisation time,and compli-cation rate as compared to the control group(P>0.05).Conclusion Preoperative enteral nutritional support combined with modified Ivor-Lewis surgery for esophageal cancer improves postoperative nutritional status,and ren-ders less effect on postoperative lung function and peripheral blood GATA3 and Foxp3 mRNA expression.

This article is based on ZHANG Jingyue's theory of yin-yang holism to explore the etiology， pathogenesis， and treatment of acute exacerbation of rheumatoid arthritis-associated interstitial lung disease （RA-ILD）. It is believed that the foundation of acute exacerbation of RA-ILD lies in real yin insufficiency and yin fail to control yang； external pathogen attacking is a common cause of acute exacerbation of RA-ILD. For treatment， it is important to first suppress ministerial fire by prescribing modified Yinhuo Decoction （引火汤）； if ministerial fire submerged， focus should be on nourishing both yin and yang； if real yin deficiency is the main issue， modified Zuogui Pill （左归丸） should be used； if real yang deficiency is prominent as well， modified Yougui Pill （右归丸） can be chosen. When yin and yang balanced， the disease could be solved.

Objective:To investigate the longitudinal relationship between solution-focused thinking and de-pressive symptoms in college students.Methods:A total of 261 college students were assessed with the Solution-Fo-cused Inventory(SFI)and Self-rating Depression Scale(SDS)in a 3-month interval.Data were analyzed with re-petitive measures analysis of variance and the cross-lagged panel model.Results:The detection rates for depressive symptoms at baseline and 3-month laterwere 39.46％and 47.89％,respectively.The scores of problem disengage-ment showed decrease after 3 months(P＜0.01).In the cross-lagged model,the baseline scores of SFI could signif-icantly predict the decrease in scores of SDS after 3 months(β=-0.19,P＜0.05),while the baseline scores of SDS could not predict the scores of SFI after 3 months(β=-0.05,P＞0.05).Conclusion:The findings suggest that solution-focused thinking may alleviate depressive symptoms.
