AIM: To evaluate the safety and efficacy of low-dose transscleral cyclophotocoagulation(TSCP)in the management of persistent ocular hypertension after an acute attack of angle-closure glaucoma(AACG).METHODS:This retrospective study enrolled patients diagnosed with persistent ocular hypertension after an acute AACG attack at the No.988 Hospital of the Joint Logistics Support Force of the Chinese PLA between September 2023 and September 2024. All patients underwent low-dose TSCP using a semiconductor diode laser. Subsequent cataract surgery combined with goniosynechialysis was performed once intraocular pressure(IOP)was stabilized. Changes in anterior chamber depth(ACD), best-corrected visual acuity(VA), and IOP were compared before and after TSCP, as well as before and after phacoemulsification. Post-TSCP complications were also documented.RESULTS: A total of 21 patients(21 eyes)were enrolled, including 8 males and 13 females, with a mean age of 67.95±7.25 y. Compared with pre-cyclophotocoagulation values, ACD increased significantly at 3 d post-TSCP(1.49±0.18 vs 1.22±0.21 mm; P<0.001). BCVA and IOP decreased significantly at 1 d post-TSCP, pre-phacoemulsification, 1 wk post-phacoemulsification, and 1 mo post-phacoemulsification compared with pre-TSCP IOP(all P<0.01). Regarding postoperative complications, 2 eyes experienced pain on the day of the procedure, 5 eyes developed mild corneal endothelial folds, 2 eyes exhibited moderate anterior chamber inflammatory reaction, and 12 eyes showed shallow ciliary body detachment. No serious complications occurred during the 1-month follow-up period.CONCLUSION:Low-dose TSCP appears to be an effective bridging therapy for patients with persistent ocular hypertension following an AACG attack. It facilitates rapid IOP reduction, alleviates symptoms, and helps preserve visual function with a favorable safety profile, thereby reducing the risks associated with subsequent intraocular surgery.

ObjectiveTo investigate the in vivo anti-inflammatory effects of the triterpenoid saponin-enriched fraction Fr.B4 from the She medicine Clematis florida (C. florida) in a rat model of phenol-induced cervicitis and to preliminarily explore its potential mechanisms of action. MethodsThirty 6–8-week-old female SPF-grade SD rats were randomly assigned to three groups: control, cervicitis model, and C. florida treatment group, with 10 rats in each group. The model and C. florida treatment groups were induced with cervicitis by vaginal injection of 25% phenol gel (once every 2 d, for a total of three injections), and the vulva and cervix were examined to assess the effectiveness of model establishment. After successful modeling, the C. florida treatment group was administered Fr.B4 at 290 mg/kg daily by gavage (dissolved in normal saline), whereas the model group received an equal volume of normal saline; both treatments continued for 2 weeks. The control group received no modeling procedure and was administered normal saline for 2 weeks. After the last intervention, fresh feces and urine samples were collected from all rats. The rats were euthanized after anesthesia with 40 mg/kg Zoletil 50, and the serum and cervical tissue samples were harvested. ELISA was used to measure the levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) in rat serum and cervical tissue. Hematoxylin and eosin (HE) staining was performed to observe the pathological changes in cervical tissue. Liquid chromatography-mass spectrometry was employed to analyze differential metabolites in feces and urine, followed by Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment and core metabolite analysis. 16S rDNA sequencing was used to assess the gut microbiota structure and diversity in each group. Statistical analysis was conducted using GraphPad Prism 9.0. ResultsCompared with the control group, rats in the model group exhibited cervical redness, swelling, and erosion, with significant increases in TNF-α, IL-1β, and IL-6 levels in both serum and cervical tissue (P<0.05 or P<0.01). Pathological examination of cervical tissue showed thickening of the squamous epithelium, infiltration of inflammatory cells, and edema. Compared with the model group, rats with C. florida treatment showed marked alleviation of cervicitis symptoms, with significantly reduced levels of pro-inflammatory cytokines in serum and cervical tissue (P<0.05 or P<0.01). Cervical tissue edema was alleviated, inflammatory cells were reduced, and squamous epithelium thickening was ameliorated. Metabolomics analysis revealed 346 and 564 differential metabolites in the feces and urine between the model and control groups, respectively. After treatment with Fr.B4, 236 and 451 metabolites in the feces and urine showed significant shifts toward control levels, involving pathways including cyclic adenosine monophosphate (cAMP) signaling, AMP-activated protein kinase (AMPK) signaling, and glutathione metabolism. Anti-inflammatory metabolites like boswellic acid and oleanolic acid were increased (P<0.01 or P<0.001). Gut microbiota analysis showed dysbiosis in the model group, with an imbalance in the Firmicutes/Bacteroidetes ratio. The Fr.B4 treatment remodeled the gut microbiota. The α-diversity of microbiota shifted toward that of the control group. Specific bacterial genera were found to correlate significantly with metabolites (P<0.05 or P<0.01). ConclusionThe triterpenoid saponin-enriched fraction Fr.B4 from She medicine C. florida may exert anti-cervicitis effects by reducing pro-inflammatory cytokine levels, modulating the gut microbiota balance, and remodeling metabolism.

As new evidence emerges, treatment strategies toward the functional cure of chronic hepatitis B are evolving. In 2019, a panel of national hepatologists published a Consensus Statement on the functional cure of chronic hepatitis B. Currently, an international group of hepatologists has been assembled to evaluate research since the publication of the original consensus, and to collaboratively develop the updated statements. The 2.0 Consensus was aimed to update the original consensus with the latest available studies, and provide a comprehensive overview of the current relevant scientific literatures regarding functional cure of hepatitis B, with a particular focus on issues that are not yet fully clarified. These cover the definition of functional cure of hepatitis B, its mechanisms and barriers, the effective strategies and treatment roadmap to achieve this endpoint, in particular new surrogate biomarkers used to measure efficacy or to predict response, and the appropriate approach to pursuing a functional cure in special populations, the development of emerging antivirals and immunomodulators with potential for curing hepatitis B. The statements are primarily intended to offer international guidance for clinicians in their practice to enhance the functional cure rate of chronic hepatitis B.

Objective To establish a method for rapid detection of tramadol in urine by liquid-liquid extraction（LLE）-surface-enhanced Raman spectroscopy （SERS）. Methods Tramadol was extracted from urine with chloroform∶isopropyl alcohol （9∶1） extractant and detected in urine samples by enhanced Raman spectroscopy （wavelength 785 nm）. Results The quantitative curve of tramadol was Y=204.35 X−465.62, r=0.9952, and the linear range was 1-100 μg/ml. The detection limit of tramadol by this method （S/N=3） was 0.53 μg/ml. The sensitivity of SERS was higher than that of conventional methods, and it had reasonable reproducibility. Conclusion This method is simple, efficient and economical, and can be used for qualitative and quantitative analysis of tramadol personalized medicine.

BACKGROUND: Asthma is a common chronic inflammatory airway disease and intermittent hypoxia is increasingly recognized as a factor that may impact disease progression. The present study investigated whether intermittent hypoxia (IH) could aggravate asthma by promoting hypoxia-inducible factor-1α (HIF-1α)/nucleotide-binding oligomerization domain (NOD)-like receptor pyrin domain-containing protein 3 (NLRP3)/interleukin (IL)-1β-dependent pyroptosis and the inflammatory response and further elucidated the underlying molecular mechanisms involved. METHODS: A total of 49 patients diagnosed with severe bronchial asthma and diagnosed by polysomnography were enrolled at Tongji Hospital, Tongji Medical College of Huazhong University of Science and Technology, between January 2022 and December 2022, and their general data and induced sputum were collected. BEAS-2B cells were treated with IL-13 and subjected to IH. An ovalbumin (OVA)-treated mouse model was also used to assess the effects of chronic intermittent hypoxia (CIH) on asthma. Pyroptosis, the inflammatory response, and related signalling pathways were assessed in vivo and in vitro . RESULTS: In this study, as the apnoea and hypopnea index (AHI) increased, the proportion of patients with uncontrolled asthma increased. The proportions of neutrophils and the levels of IL-6, IL-8, HIF-1α and NLRP3 in induced sputum were related to the AHI. NLRP3-mediated pyroptosis, which could be mediated by the HIF-1α signalling pathway, was activated in IL-13 plus IH-treated BEAS-2B cells and in the lungs of OVA/CIH mice. HIF-1α downregulation significantly reduced lung pyroptosis and ameliorated neutrophil inflammation by modulating the NLRP3/IL-1β pathway both in vitro and in vivo . Similarly, pretreatment with LW6, an inhibitor of HIF-1α, effectively blocked the generation of inflammatory cytokines in neutrophils. In addition, administration of the NLRP3 activator nigericin obviously increased lung neutrophil inflammation. CONCLUSIONS Obstructive sleep apnoea-hypopnea syndrome (OSAHS) is a risk factor for asthma exacerbation. IH aggravates neutrophil inflammation in asthma via NLRP3/IL-1β-dependent pyroptosis mediated by the HIF-1α signalling pathway, which should be considered a potential therapeutic target for the treatment of asthma with OSAHS.

Objective To analyze the value of actin-related protein 2(ACTR2)and DEAD-box RNA helicase 3X-linked(DDX3X)expression in evaluating the severity of Rotavirus gastroenteritis(RVGE)in children.Methods A total of 153 children with rotavirus gastroenteritis admitted to Handan Maternal and Child Health Hospital from September 2022 to September 2024 were selected as the research objects.According to the severity of RVGE,the children with RVGE were divided into mild group(n=60),moderate group(n=71)and severe group(n=22).In addition,60 healthy children were randomly selected as the healthy group.The clinical data of the light group,the medium group and the heavy group were compared.The expression levels of ACTR2 and DDX3X in serum of each group were detected by real-time fluorescence quantitative PCR.ROC curve was used to analyze the evaluation value of combined detection of serum ACTR2 and DDX3X in children with severe RVGE.Results The age of children with RVGE in the severe group was significantly lower than that in the mild group and the moderate group,and the differences were statistically significant(Z=8.307,5.885,all P＜0.001).There were statistically significant differences in dehydration and diarrhea among the three groups(F=9.434,126.080,all P＜0.05).The expression levels of ACTR2(1.20±0.28)and DDX3X(1.22±0.37)in RVGE group were significantly higher than those in control group(1.01±0.02,1.04±0.09),and the differences were statistically significant(t=5.071,3.584,all P＜0.05).The expression levels of ACTR2[1.11±0.23,1.23±0.21,1.42(1.25,1.57)]and DDX3X[1.14±0.22,1.25±0.24,1.32(1.23,1.62)]in the serum of the mild group,the moderate group and the severe group increased in turn,and the differences were statistically significant(Z=27.196,18.013,all P＜0.05).The ROC curve analysis results showed that the combined detection of serum ACTR2 and DDX3X predicted the AUC(95%CI)of critically ill RVGE patients,with higher sensitivity and specificity than the detection of the two alone(Z=2.573,2.101,P=0.014,0.034).Conclusion The expression levels of serum ACTR2 and DDX3X are closely related to the severity of RVGE.The combined detection of the two has a high predictive value for the diagnosis of the severity of RVGE.

OBJECTIVES: This study aimed to explore the clinical efficacy of severe early childhood caries (SECC) treatment combined with local anesthesia under general anesthesia. METHODS: A total of 108 children under 6 years old who underwent SECC dental treatment under general anesthesia at the Department of Pediatric Dentistry, Third Affiliated Hospital of Air Force Medical University from March to December 2023 were selected as the study subjects, with American Society of Anesthesiologists (ASA) classification of classⅠor Ⅱ. The study subjects were divided into a control group (n=54) and an experimental group (n=54) by retrieving intraoperative cases and postoperative follow-up records. The control group was given general anesthesia through inhalation combined with nasotracheal intubation, whereas the experimental group was given local anesthesia with 2% lidocaine on each treated tooth on the basis of general anesthesia. The basic information, preoperative anesthesia depth, hemodynamic changes during different surgical procedures, postoperative pain, and adverse reactions in the two groups were recorded and analyzed. RESULTS: No statistically significant difference was found in the basic information and preoperative anesthesia depth between the two groups (P>0.05). Among the three procedures (pulpotomy, root canal treatment, and tooth extraction), the three observed indicators in the experimental group were significantly lower than those in the control group (P<0.05). The proportion of patients in the experimental group who needed to take analgesic measures in accordance with the modified facial pain scale (FPS-R) score was significantly lower than that in the control group at postoperative wakefulness and 2 h after surgery (P<0.05). Meanwhile, no statistically significant difference was observed between the groups at 24 h after surgery (P>0.05). The proportion of patients in the experimental group who needed to take analgesic measures on the basis of the parent posto-perative pain measurement (PPPM) score was significantly lower than that in the control group when they were awake after surgery (P<0.05). No statistically significant difference was found between the groups at 2 and 24 h after surgery (P>0.05). Moreover, no statistically significant difference was observed in the incidence of adverse reactions between the two groups at 24 h after surgery (P>0.05). CONCLUSIONS The combination of local anesthesia during SECC dental treatment under general anesthesia results in minimal changes in intraoperative hemodynamics and mild postoperative pain response, hence worthy of clinical promotion.

Objective:To establish an evaluation index system for patient safety education targeted at undergraduate nursing interns.Methods:Based on the CIPP (Context, Input, Process, Product) evaluation model, a preliminary draft of the index system was developed using a literature review and semi-structured interviews. The Delphi method and the Analytic Hierarchy Process were applied to finalize the index system.Results:Two rounds of Delphi expert consultation were conducted. In the first round, 23 questionnaires were distributed, and 20 valid responses were received (effective response rate: 86.96%) . Among them, 15 experts (75.00%) provided revision suggestions. In the second round, 20 questionnaires were distributed, and 19 valid responses were received (effective response rate: 95.00%) , with two experts (10.53%) offering suggestions. The expert authority coefficients for the two rounds were 0.900 and 0.921, respectively. Kendall's coordination coefficients were 0.272 and 0.273 ( P<0.01) . The final evaluation system consisted of four first-level indicators, eight second-level indicators, and 18 third-level indicators. Conclusions:The evaluation index system constructed in this study is scientifically grounded and reliable. However, its practical utility and applicability require further validation.
