Objective To explore the medication rules of Professor Hua Baojin in the treatment of subsolid pulmonary nodules through retrospective analysis and data mining techniques. Methods The prescriptions of patients with subsolid pulmonary nodules who were diagnosed and treated by Professor Hua Baojin at Guang’anmen Hospital of the Chinese Academy of Chinese Medical Sciences from January 1, 2021 to December 31, 2024 were retrospectively collected. Data were imported into the Ancient and Modern Medical Case Cloud Platform for analysis of drug frequency, four natures and five flavors, meridian tropism, drug association, and hierarchical clustering. Results A total of 455 prescriptions were included, containing 205 kinds of traditional Chinese medicines, with a total frequency of 12048 times. Fifty-seven commonly used drugs were screened out, among which drugs with high frequencies included astragalus membranaceus (raw) and hawthorn fruit (charred). The nature of the drugs was mainly warm, cold, and neutral. The flavor of the drugs was mostly sweet, bitter, and pungent. The meridians they belonged to mainly included the lung, spleen, and liver meridians. Their efficacy was mainly tonifying deficiency, clearing heat, resolving phlegm, and relieving cough and asthma. Association analysis obtained 19 pairs of drug combinations, 21 groups of three-drug combinations, and four groups of four-drug combinations. Hierarchical clustering obtained 10 groups of drug combinations. Conclusion On the basis of the core pathogenesis of subsolid pulmonary nodule, Professor Hua applies the theory of regulating qi and detoxifying; regulating the qi of the liver, spleen, and lung; and detoxifying the toxins of phlegm and blood stasis, providing valuable experience for the clinical treatment of SSN.

Objective To explore the clinical information of female patients with pulmonary nodules and the distribution of traditional Chinese medicine (TCM) syndromes and their elements. Methods A cross-sectional study was conducted to collect the basic information, medical history data, image data, and four diagnostic information of female patients with pulmonary nodules. The distribution characteristics of TCM syndromes and their elements in female patients with pulmonary nodules were determined by KMO test, Bartlett spherical test, systematic cluster analysis, chi-square test, and other methods. Results A total of 721 female patients with pulmonary nodules were included in this study. The patients were mainly 45-59 years old, had secondary school education or above, and had a history of oil smoke exposure as clinical characteristics. The pulmonary nodules were mainly 6-10 mm in size and appeared as multiple and ground glass nodules. The clinical symptoms were mainly fatigue, emotional irritability, and shortness of breath. The main syndromes of disease location were the spleen, liver, and lung; and the main syndromes of disease were phlegm, dampness, and qi deficiency. The main complex syndromes were spleen deficiency and dampness, liver stagnation, and qi/yin deficiency. Conclusion Middle age, high education, and multiple small ground glass nodules are the clinical characteristics of female patients with pulmonary nodules. Exposure to oil smoke is an important cause of the occurrence of female pulmonary nodules. During treatment, attention should be paid to strengthening the spleen, removing dampness, soothing the liver, regulating and tonifying qi, and nourishing yin.

Objective:To investigate the effect and potential mechanism of circular RNA-centrosome and spindle pole-associated protein 1 (circ-CSPP1) on the malignant biological behavior of hepatoma cells.Methods:Real-time fluorescence quantitative polymerase chain reaction (RT-PCR) was used to detect the expressions of circ-CSPP1 and microRNA-582-5p (miR-582-5p) in hepatoma cells, and Western blotting was used to detect the expression of karyopherins α2 (KPNA2). HepG2 cells were divided into the circ-CSPP1 overexpression group, the circ-CSPP1 overexpression control group, the si-CSPP1 group, the si-NC group, the si-CSPP1+ miR-582-5p inhibition group, and the si-CSPP1+ miR-582-5p inhibition control group. circ-CSPP1 overexpression plasmid, CSPP1 interfering small RNA, CSPP1 interfering small RNA, miR-582-5p inhibition sequence and negative control were transfected respectively in these groups. Cell proliferation in each group was detected by 5-acetylene-2'-deoxyuridine (Edu), invasion ability was detected by Transwell assay, and the binding of circ-CSPP1 and KPNA2 to miR-582-5p was verified by dual-luciferase assay. In the si-CSPP1 group, HepG2 cells transfected with si-CSPP1 lentivirus were subcutaneously injected into the back of nude mice ( n=12), and in the si-NC group, HepG2 cells transfected with negative control lentivirus ( n=12) were injected. The tumor mass, volume, circ-CSPP1 and KPNA2 were detected. Results:In the circ-CSPP1 overexpression group, the relative expression of circ-CSPP1 was (1.68±0.17), the expression of KPNA2 was (1.52±0.16), and the number of invasive cells in the 100-fold field of view was (128.4±13.5), which were all higher than those in the circ-CSPP1 overexpression control group [(1.25±0.16), (1.24±0.15), (128.4±13.5)], while the expression of miR-552-5p was lower than that in the circ-CSPP1 overexpression control group [(0.96±0.11) vs (1.31±0.15)]; The relative expression of circ-CSPP1 in the si-CSPP1 group was (1.02±0.13), KPNA2 was (0.74±0.09), and the number of invasive cells was (53.5±6.7), which were lower than those in the si-NC group [(1.28±0.14), (1.22±0.13), (74.6±8.3)], while the expression of miR-582-5p was higher than that in the si-NC group [(1.71±0.18) vs (1.32±0.14)]; The expression of circ-CSPP1 and KPNA2 and the number of invasion cells in the si-CSPP1+ miR-582-5p inhibition group was higher than that in the si-CSPP1+ miR-582-5p inhibition control group, and the differences were statistically significant (all P<0.05). The results of cell proliferation were consistent with those of invasion. The dual-luciferase gene report showed that, compared with the miR-NC group, the relative luciferase activity in HepG2 cells co-transfected with circ-CSPP1-WT or KPNA2-WT wild-type reporter vectors in the miR-882-5p mimic group decreased [(0.46±0.05) vs (1.03±0.11), (0.42±0.03) vs (1.01±0.09)]. The differences were all statistically significant (both P<0.05). However, there was no statistically significant difference in the relative luciferase activity in HepG2 cells co-transfected with the circ-CSPP1-MUT or KPNA2-MUT mutant reporter vectors (both P>0.05). The tumor weight, volume and circ-CSPP1 and KPNA2 expressions in tumor tissue of nude mice in the si-CSPP1 group were all lower than those in the si-NC group, and the expression of miR-582-5p was higher than that in the si-NC group. The differences were statistically significant (all P<0.05). Conclusion:Inhibition of circ-CSPP1 suppressed the malignant biological behavior of hepatoma cells and tumor growth by upregulating miR-582-5p and downregulating KPNA2.

Abstract Cardiovascular disease is one of the leading causes of death worldwide, and myocardial remodeling is at the core of the development and progression of most cardiovascular diseases. Purinergic ligand-gated ion channel 7 receptor(P2X7R) is a member of the purinergic receptor family, which is expressed in immune cells, cardiac smooth muscle cells, and endothelial cells, and plays an important role in pathological processes related to immune system regulation, neuroprotection, and inflammatory responses. Activation of P2X7R plays an important role in myocardial remodeling, including myocardial fibrosis, myocardial hypertrophy, and heart failure. Therefore, this article reviews the structural and functional properties of P2X7R and its mechanism of action in myocardial remodeling.

Endovascular aneurysm repair (EVAR) has increasingly replaced traditional open surgery for abdominal aortic aneurysms due to its minimally invasive adventure; however, postoperative circulatory management plays a critical role in patient outcomes. This review systematically examines three core strategies in post-EVAR care. Firstly, hemodynamic management requires precise regulation of blood pressure and cardiac output to prevent hypertension-induced stent graft migration or aneurysm sac expansion, while avoiding hypotension-related visceral hypoperfusion. Secondly, fluid balance optimization emphasizes individualized adjustment of crystalloid-to-colloid ratios through dynamic monitoring, aiming to maintain organ perfusion while protecting cardiopulmonary function. Thirdly, anticoagulation and thrombosis prevention strategies must balance the intensity of low molecular weight heparin or direct oral anticoagulants against bleeding risks, incorporating mechanical prophylaxis to further reduce thrombotic events.

Haglund syndrome (HS) is a common cause for posterior heel pain in ankle surgery, but the etiology of heel pain is so complicated that its pathogenic factors are currently unclear. For such diseases as posterior heel pain, conservative treatment should be carried out first. However, as their cause is not eliminated their symptoms are likely to recur. With the rapid development of biotechnology, imaging technology, and arthroscopy technology, biological therapy and minimally invasive surgery have gradually become the main treatments for HS. This review expounds on the factors, mechanisms, imaging diagnostic methods, options of conservative and surgical treatments concerning HS, hoping to help the clinical treatment of HS.

To summarize the diagnosis and management of a highly sensitized renal transplant recipient who developed Legionella pneumophila infection during the perioperative period. A 48-year-old male recipient presented early after transplantation with both acute allograft rejection and pulmonary infection. The acute rejection episode was successfully reversed with appropriate treatment, whereas the pulmonary infection continued to progress. Initial microbiological tests were negative, and empirical antimicrobial therapy was ineffective. Legionella pneumophila was subsequently detected by metagenomic next-generation sequencing of bronchoalveolar lavage fluid obtained via bronchoscopy. Following combined therapy with moxifloxacin and tigecycline, along with withdrawal of immunosuppressive agents, the pulmonary lesions completely resolved.

Objective Cheng's Juanbi Decoction(CSJBD)is a classic traditional Chinese medicine formula for treating rheumatoid arthritis(RA),exhibiting significant clinical efficacy,but the underlying mechanisms remain unclear.We investigated whether CSJBD inhibited RA pathology by blocking the WTAP-Wnt7b-Wnt/β-catenin signaling axis using a collagen-induced arthritis(CIA)mouse model and fibroblast-like synoviocytes(FLSs)derived from RA patients(RA FLSs)and examined the underlying mechanisms.Methods We conducted in vivo experiments.Male C57BL/6 mice weighing 17 to 20 g were used to establish the CIA model.The mice were assigned to 6 groups,including the normal group,the model(CIA)group,the model+CSJBD-L(8.1 g/kg)group,the model+CSJBD-M(16.2 g/kg)group,the model+CSJBD-H(32.4 g/kg)group,and the model+leflunomide(LEF)(0.05 mg/10 g)group,with 10 mice in each group.CSJBD was administered twice daily via gastric gavage,while LEF was administered once daily via gastric gavage,for a duration of 28 days.We also conducted in vitro experiments.RA FLSs were assigned to 4 groups,including the RA FLSs+CSJBDS-L group receiving 10%CSJBDS-containing serum,the RA FLSs+CSJBDS-M group receiving 15%CSJBDS-containing serum,the RA FLSs+CSJBDS-H group receiving 20%CSJBDS-containing serum,and the RA FLSs+NC group(negative control).To study whether WTAP regulated Wnt7b,RA FLSs were divided into the RA FLSs group,the RA FLSs+si-WTAP#3 group,the RA FLSs+si-WTAP#3+Wnt7b-OE group,and the RA FLSs+si-WTAP#3+Wnt7b-NC group.To study the underlying mechanism by which CSJBT affected RA FLSs,RA FLSs were divided into the RA FLSs group,the RA FLSs+CSJBDS-M group,the RA FLSs+CSJBDS-M+Wnt7b-OE group,and the RA FLSs+CSJBDS-M+NC group.We used ultra-high performance liquid chromatography(UPLC)to identify and quantify key monomer compounds from CSJBD as quality criteria for CSJBD preparation.Bioinformatics,CCK-8,RT-qPCR,Western blot,immunofluorescence,and related methods were employed to assess the therapeutic efficacy and underlying mechanisms of CSJBD in treating RA.Results According to the UPLC analysis,ferulic acid,osthole,mulberroside A,notopterol,and gentiopicroside were identified as quality control standards for the preparation of CSJBD formula.CSJBD improved RA pathology in CIA mice,reduced the levels of interleukin(IL)-6,IL-1β,IL-8,and tumor necrosis factor-α(TNF-α)in their serum,and decreased the expression of RA pathological genes MMP3 and fibronectin,with the difference between groups being statistically significant.Bioinformatics analysis suggested that CSJBD might inhibit RA pathology by suppressing the Wnt/β-catenin signaling pathway through Wnt7b.Experimental results showed that the expression of WTAP and Wnt7b was significantly increased in RA.After knocking down WTAP,the expression of Wnt7b was significantly reduced,and the Wnt/β-catenin signaling pathway was also inhibited,with the difference between groups being statistically significant(P<0.05),confirming that WTAP regulated the pathway via Wnt7b.According to experimental verification,CSJBD significantly inhibited the Wnt/β-catenin signaling pathway and the proliferation of RA FLSs.Wnt7b overexpression reversed the inhibitory effect of CSJBD on the Wnt/β-catenin signaling pathway and the proliferation of RA FLSs,indicating that Wnt7b is the direct target of CSJBD.Conclusion CSJBD inhibits RA pathology by blocking the WTAP-Wnt7b-Wnt/β-catenin signaling axis,with Wnt7b identified as a direct therapeutic target of CSJBD.
