Objective To analyze the external radiation dose rate and radiation protection measures during treatment of a patient with hepatocellular carcinoma (HCC) who underwent ⁹⁰Y selective internal radiotherapy (⁹⁰Y-SIRT). Methods A male HCC patient who received ⁹⁰Y-SIRT with an activity of 4.65×10⁹ Bq was selected as the research subject using retrospective analysis. External radiation dose rate meters were used to detect ambient dose equivalent rates around the radiation worker, the HCC patient, and the workplace during treatment. Surface contamination meters were used to detect surface contamination levels of the radiation worker and the workplace. Results The ambient dose equivalent rate around the interventional radiology staff during treatment ranged from 3.7 to 39.0 μSv/h. The patient's ambient dose equivalent rate of surgical site at distances of 30, 100, and 200 cm ranged from 45.0 to 5.6, 4.4 to 0.4, and 0.4 to 0.1 μSv/h respectively without protection, and 14.0 to 3.4, 3.2 to 0.3, and 0.4 to 0.1 μSv/h respectively when the surgical site was covered with a 1.0 mmPb lead rubber drape after 0.0 to 161.0 hours of the surgery. In the nuclear medicine department, ambient dose equivalent rate of the workplace ranged from 0.4 to 740.0 μSv/h. The ambient dose equivalent rate around all monitoring points in the digital subtraction angiography operating room accounted at 0.1 μSv/h, and the observation ward ranged from 0.1 to 0.2 μSv/h. The β surface contamination levels of the radiation worker and workplace were below the minimum detection limit (0.16 Bq/cm²). Conclusion Radiation doses for both HCC patients and radiation worker remained within acceptable limits when appropriate protective equipment was used. A well-designed workplace layout is essential to ensure effective implementation of radiation protection.

BACKGROUND: Generalized pustular psoriasis (GPP), a rare and recurrent autoinflammatory disease, imposes a substantial burden on patients and society. Awareness of GPP in China remains limited. METHODS: This cross-sectional survey, conducted between September 2021 and May 2023 across 14 hospitals in China, included GPP patients of all ages and disease phases. Data collected encompassed demographics, clinical characteristics, economic impact, disease severity, quality of life, and treatment-related complications. Risk factors for GPP recurrence were analyzed. RESULTS: Among 127 patients (female/male ratio = 1.35:1), the mean age of disease onset was 25 years (1st quartile [Q1]-3rd quartile [Q3]: 11-44 years); 29.2% had experienced GPP for more than 10 years. Recurrence occurred in 75.6% of patients, and nearly half reported no identifiable triggers. Younger age at disease onset ( P  = 0.021) and transitioning to plaque psoriasis ( P  = 0.022) were associated with higher recurrence rates. The median diagnostic delay was 8 months (Q1-Q3: 2-41 months), and 32.3% of patients reported misdiagnoses. Comorbidities were present in 53.5% of patients, whereas 51.1% experienced systemic complications during treatment. Depression and anxiety affected 84.5% and 95.6% of patients, respectively. During GPP flares, the median Dermatology Life Quality Index score was 19.0 (Q1-Q3: 13.0-23.5). This score showed significant differences between patients with and without systemic symptoms; it demonstrated correlations with both depression and anxiety scores. Treatment costs caused financial hardship in 55.9% of patients, underscoring the burden associated with GPP. CONCLUSIONS The substantial disease and economic burdens among Chinese GPP patients warrant increased attention. Patients with early onset disease and those transitioning to plaque psoriasis require targeted interventions to mitigate the high recurrence risk.

This study predicts the quality markers(Q-markers) for the cough-relieving and phlegm-expelling effects of Kening Granules based on pharmacodynamics, plasma drug chemistry, network pharmacology, and pharmacokinetics. Strong ammonia solution spray and phenol red secretion assays were employed to evaluate the cough-relieving and phlegm-expelling effects of Kening Granules. Twentysix absorbed prototype components of Kening Granules were identified by ultra high performance liquid chromatography coupled with QExactive Plus quadrupole/Orbitrap high resolution mass spectrometry(UHPLC-Q-Exactive Plus Orbitrap HRMS). Through network pharmacology, 11 potential active components were screened out for the cough-relieving and phlegm-expelling effects of Kening Granules. The 11 components acted on 40 common targets such as IL6, TLR4, and STAT3, which mainly participated in PI3K/Akt, HIF-1, and EGFR signaling pathways. Pharmacokinetic quantitative analysis was performed for 7 prototype components. Three compounds including azelaic acid, caffeic acid, and vanillin were identified as Q-markers for the cough-relieving and phlegm-expelling effects of Kening Granules based on their effectiveness, transmissibility, and measurability. The results of this study are of great significance for clarifying the pharmacological substance basis, optimizing the quality standards, and promoting the clinical application of Kening Granules.

This study identified blood-entering components of Anshen Dropping Pills and explored their anti-insomnia effects and mechanisms. The main blood-entering components of Anshen Dropping Pills were detected and identified by UPLC-Q-TOF-MS/MS. The rationality of the formula was assessed by using enrichment analysis based on the relationship between drugs and symptoms, and core targets of its active components were selected as the the potential anti-insomnia targets of Anshen Dropping Pills through network pharmacology analysis. Furthermore, protein-protein interaction(PPI) network, Gene Ontology(GO) enrichment analysis, and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway analysis were performed on the core targets. An active component-core target network for Anshen Dropping Pills was constructed. Finally, the effects of low-, medium-, and high-dose groups of Anshen Dropping Pills on sleep episodes, sleep duration, and sleep latency in mice were measured by supraliminal and subliminal pentobarbital sodium experiments. Moreover, total scores of the Pittsburgh sleep quality index(PSQI) scale was used to evaluate the changes before and after the treatment with Anshen Dropping Pills in a clinical study. The enrichment analysis based on the relationship between drugs and symptoms verified the rationality of the Anshen Dropping Pills formula, and nine blood-entering components of Anshen Dropping Pills were identified by UPLC-Q-TOF-MS/MS. The network proximity revealed a significant correlation between eight components and insomnia, including magnoflorine, liquiritin, spinosin, quercitrin, jujuboside A, ginsenoside Rb_3, glycyrrhizic acid, and glycyrrhetinic acid. Network pharmacology analysis indicated that the major anti-insomnia pathways of Anshen Dropping Pills involved substance and energy metabolism, neuroprotection, immune system regulation, and endocrine regulation. Seven core genes related to insomnia were identified: APOE, ALB, BDNF, PPARG, INS, TP53, and TNF. In summary, Anshen Dropping Pills could increase sleep episodes, prolong sleep duration, and reduce sleep latency in mice. Clinical study results demonstrated that Anshen Dropping Pills could decrease total scores of PSQI scale. This study reveals the pharmacodynamic basis and potential multi-component, multi-target, and multi-pathway effects of Anshen Dropping Pills, suggesting that its anti-insomnia mechanisms may be associated with the regulation of insomnia-related signaling pathways. These findings offer a theoretical foundation for the clinical application of Anshen Dropping Pills.

OBJECTIVE: To review the clinical applications of functional perforator flaps in restoring human body functions. METHODS: An extensive literature review was conducted on both domestic and international publications to summarize the clinical use of functional perforator flaps for functional restoration. RESULTS: Perforator flaps are among the most commonly used flaps in reconstructive surgery. Beyond providing soft tissue repair, they are increasingly employed to reconstruct diverse bodily functions, leading us to propose the concept of the "functional perforator flap". Although various forms of functional perforator flaps are currently utilized, reports are predominantly scattered case studies, lacking systematic organization. Commonly used functional perforator flaps can be categorized into five types: chimeric perforator flaps, perforator flaps for nerve function restoration, perforator flaps for lymphatic drainage enhancement, flow-through perforator flaps, and perforator flaps for restoring bone and joint motion. These flaps significantly broaden the application scope of perforator flaps, elevating the goal of reconstruction from mere wound repair to achieving repair concurrent with functional reconstruction. CONCLUSION The application of various functional perforator flap designs significantly improves wound reconstruction outcomes and represents an effective approach for managing complex defects. Future developments will undoubtedly see more forms of functional perforator flaps reported to meet increasingly sophisticated reconstructive demands.

Salvia miltiorrhiza (Danshen) is a traditional Chinese herb that is commonly known for its cardiovascular and hepatoprotective benefits. Recent studies have confirmed that Danshen and its bioactive components can influence gut microbial homeostasis, thereby affecting Helicobacter pylori (HP) colonization in the human stomach. HP is a bacterial pathogen associated with various gastrointestinal diseases. Current HP treatments mainly involve antibiotics and proton pump inhibitors. However, their efficacy is strongly compromised by the rapid emergence of antibiotic resistance in HP and genetic heterogeneity among patients. The interaction between Danshen and gut microbial status provides a novel perspective for HP treatment. Understanding the medical properties of Danshen in altering gut microbiota and eliminating HP, as well as the underlying mechanisms, is important for improving human gastrointestinal healthcare. This review investigates the interaction between Danshen and gut microbiota and its impact on HP infection using databases including Web of Science, PubMed, and Google Scholar. We explored the unconventional intersection between Danshen, gut microbiota, and HP infection, shedding light on their intricate interplay and potential therapeutic implications. A comprehensive understanding of this interaction provides valuable insights into developing novel therapeutic strategies that target the gut microbiota to mitigate HP-associated gastrointestinal disorders.

Objective:To investigate the predictive value of Doppler ultrasonography combined with cytokeratin fragment 19 (Cyfra21-1) and soluble interleukin-2 receptor (sIL-2R) in cervical lymph node metastasis of thyroid micropapillary carcinoma.Methods:102 patients with minimal papillary carcinoma of thyroid confirmed by surgery and pathology admitted to Ultrasound Department, Shanxi Cancer Hospital from Aug. 2020 to Aug. 2023 were selected and treated with thyroidectomy plus central region and at least one cervical lymph node dissection. Among them, There were 24 cases in the LLNM group and 78 cases in the non-LLNM group.Results:There were significant differences in age, shape, nodular and capsule contact area, tumor shape aspect ratio > 1, blood flow, microcalcification, serum Cyfra21-1 and serum sIL-2R levels between the two groups (Cyfra21-1: P<0.001, sIL-2R: P=0.001). Logistic regression analysis showed that age ≥50 years old ( OR=0.443, 95% CI: 0.217-0.904), microcalcification ( OR=2.787, 95% CI: 1.491-5.208), Cyfra21-1>3.3ng/ml ( OR=3.117, 95% CI: 1.404-6.922) and sIL-2R > 110.45pmol/L ( OR=3.408, 95% CI: 1.473-7.884) were independent risk factors for cervical lymph node metastasis in PTMC patients ( P < 0.05). The ROC curve results showed that the area under the curve of cervical lymph node metastasis predicted by Doppler ultrasound combined with Cyfra21-1 and sIL-2R was 0.82, and the sensitivity and specificity were 83.67% and 70.56%, respectively. Conclusions:The calcification features of Doppler ultrasound and the elevation of serum Cyfra21-1 and sIL-2R are closely related to cervical lymph node metastasis of thyroid micropapillary carcinoma. The combination of Doppler ultrasound with serum Cyfra21-1 and sIL-2R has important reference value in predicting cervical lymph node metastasis.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective:To investigate whether murine peroxidase reductase-5(mPRDX5)has anti-tumor activity in mice,so as to further confirm the anti-tumor activity and mechanism of recombinant peroxidase reductase-5.Methods:High purity mPRDX5 was obtained by heterologous expression and purification in vitro.Pancreatic cancer Pan02 cells were inoculated subcutaneously on the left axillary back of mice to establish a tumor bearing mouse model.Mice were randomly divided into PBS(solvent control)group,GEM(gemcitabine)50.0 mg/kg group and mPRDX5 10.0 mg/kg group,with 10 mice in each group,and the tumor related indexes were detected in mice.Results:Compared with PBS group,weight of tumor-bearing mice in GEM group was decreased obviously,while weight of mPRDX5 group was increased to a certain extent.Tumor growth was good in PBS group,according to tumor volume,com-pared with PBS group,tumor growth inhibition rates in D7 were 87.07%in GEM group and 52.82%in mPRDX5 10.0 mg/kg group,re-spectively;according to tumor weight,compared with PBS group,GEM group and mPRDX5 10.0 mg/kg group had tumor growth inhibi-tion rates of 95.39%and 48.33%in D7,respectively.Polarization state of macrophages in tumor tissues of mice in PBS group and mPRDX5 group was analyzed,and it was found that compared with PBS group,M1 macrophages expressing CD86 in tumor tissues of mice in mPRDX5 group were significantly increased,while M2 macrophages expressing CD206 were significantly decreased.Conclu-sion:mPRDX5 has significant anti-pancreatic cancer activity in mice,and the activity is exerted by promoting M1-type polarization of macrophages in the tumor microenvironment.

Chemotherapy is one of the major approaches for the treatment of metastatic lung cancer, although it is limited by the low tumor delivery efficacy of anticancer drugs. Bacterial therapy is emerging for cancer treatment due to its high immune stimulation effect; however, excessively generated immunogenicity will cause serious inflammatory response syndrome. Here, we prepared cancer cell membrane-coated liposomal paclitaxel-loaded bacterial ghosts (LP@BG@CCM) by layer-by-layer encapsulation for the treatment of metastatic lung cancer. The preparation processes were simple, only involving film formation, electroporation, and pore extrusion. LP@BG@CCM owned much higher 4T1 cancer cell toxicity than LP@BG due to its faster fusion with cancer cells. In the 4T1 breast cancer metastatic lung cancer mouse models, the remarkably higher lung targeting of intravenously injected LP@BG@CCM was observed with the almost normalized lung appearance, the reduced lung weight, the clear lung tissue structure, and the enhanced cancer cell apoptosis compared to its precursors. Moreover, several major immune factors were improved after administration of LP@BG@CCM, including the CD4⁺/CD8a⁺ T cells in the spleen and the TNF-α, IFN-γ, and IL-4 in the lung. LP@BG@CCM exhibits the optimal synergistic chemo-immunotherapy, which is a promising medication for the treatment of metastatic lung cancer.
