Objective: To investigate the barrier membrane fixation performance and enhanced guided bone regeneration (GBR) capability of a thermosensitive adhesive containing bioactive glass nanoparticles in order to provide a novel solution for membrane fixation during GBR procedures. Methods: M2NP@BGN (methoxyethyl acrylate-co-N-isopropylacrylamide-co-protocatechuic acid@Bioactive glass nanoparticle), a thermosensitive adhesive, was synthesized via free radical polymerization by compositing methoxyethyl acrylate, N-isopropylacrylamide, and protocatechuic acid into a basic adhesive that was modified with bioactive glass nanoparticle (BGN). The successful fabrication of basic adhesive M2NP was characterized by attenuated total reflection-Fourier transform infrared spectroscopy and nuclear magnetic resonance spectroscopy. The thermosensitive adhesive M2NP@BGN (BGN concentration of 1 mg/mL) was characterized by scanning electron microscopy and a rheometer. By adjusting the BGN concentration (0.1 mg/mL, 0.5 mg/mL, 1 mg/mL, and 2 mg/mL), the adhesive and mechanical strengths were investigated with a universal testing machine. Biocompatibility was evaluated with a cell counting kit-8 assay and hemolysis test to identify the optimal formulation. The optimal material’s extract was co-cultured with mouse bone marrow mesenchymal stem cells, and its osteogenic activity was examined in vitro by quantitative real-time PCR, alkaline phosphatase, and alizarin red S staining. The rat mandibular defect model was established, filled with bone graft, and divided into 3 groups based on membrane fixation method: M2NP@BGN (BGN concentration of 1 mg/mL) fixation group (M2NP@BGN), titanium nail fixation group (Nail), and unfixed control group (Negative). Bone regeneration was analyzed after 8 weeks by micro computed tomography and histological staining. Results: M2NP@BGN (BGN concentration of 1 mg/mL) was successfully synthesized and demonstrated rapid gelation under warm, humid conditions. The adhesive with a BGN concentration of 1 mg/mL exhibited the highest adhesive strength (P < 0.001) and significantly enhanced mechanical strength (P < 0.001) under 37℃ wet conditions. All formulations showed excellent biocompatibility, with cell viability > 80% and hemolysis ratio < 5%. M2NP@BGN (BGN concentration of 1 mg/mL) significantly upregulated the expression of Runx2 and Col I (P < 0.001) and enhanced the activity of osteogenic differentiation markers (P < 0.05). In the animal model, the M2NP@BGN group (BGN concentration of 1 mg/mL) achieved significantly higher bone volume fraction and better bone maturity compared to the negative and nail groups (P < 0.05). Conclusion M2NP@BGN (BGN concentration of 1 mg/mL) combines excellent wet adhesion with potent osteogenic activity, enhances the bone augmentation efficacy of membranes, and presents a novel fixation strategy with significant clinical translation potential for GBR therapy.

OBJECTIVE This study investigated the clinical implications of endothelial cell-specific molecule 1(ESM-1)in obstructive sleep apnea(OSA)patients,with particular focus on its dynamic correlation with adhesion molecules,aiming to elucidate the regulatory role of ESM-1 in OSA-associated vascular endothelial impairment.METHODS This cross-sectional study enrolled participants undergoing polysomnography(PSG)at the Sleep Medicine Center of Beijing Anzhen Hospital,Capital Medical University between March 2017 and January 2018.Based on the inclusion criteria,161 participants were ultimately included and divided into OSA group(n=118)and control group(n=43).Demographic data and polysomnography parameters were collected.We used a powerful high-throughput Multiplex Immunobead Assay technology to simultaneously test plasm cytokines levels of ESM-1,inter-cellular adhesion molecule 1(ICAM-1),vascular cell adhesion molecule 1(VCAM-1).Circulating C-reactive protein(CRP)and homocysteine(Hcy)were detected by routine blood chemistry panel.RESULTS Circulating ESM-1 levels were significantly elevated in patients with OSA compared with healthy controls[819.73(612.36-1393.47)pg/ml]vs.[286.17(114.48-513.81)pg/ml,P<0.001].After adjusting for confounding factors,we found that circulating ESM-1 levels were an independent risk factor for OSA(odds ratio=2.162,95%CI=1.522-3.072,P<0.001)and circulating ESM-1 levels were positively associated with ICAM-1 and VCAM-1 levels(β=1.977,95%CI=1.429-2.734,P<0.001).CONCLUSION Circulating ESM-1 levels were significantly increased in patients with OSA,which is closely related with adhesion molecules levels.ESM-1 may be a surrogate endothelial dysfunction marker and an independent risk factor for OSA.

[Objective] To retrospectively analyze the detection results of alanine aminotransferase (ALT) unqualified repeat blood donors in Guangzhou, so as to provide evidence for further expanding the repeat blood donor pool, reducing the rate of blood discarding and improving the qualified rate of blood test. [Methods] Blood donors with unqualified ALT in Guangzhou Blood Center from January 2018 to April 2024 were selected as the research objects. The past blood donation and population characteristics were analyzed according to the number of blood donations and ALT unqualified times. [Results] Among repeat blood donors with previous ALT disqualification, 99.5% to 99.7% did not have reactive markers for transfusion-transmitted diseases (TTD), which was higher than the rate among first-time blood donors with unqualified ALT (95.8%) (P<0.05). The rate of single-item ALT disqualification in repeat blood donors was higher in males than in females (P<0.05); it also varied by age (18-25 years > 26-35 years > 36-45 years > over 45 years) (P<0.05); and by quarter (third and fourth quarters > first and second quarters) (P<0.05). The ALT unqualified rate was significantly higher whole blood donors than that of platelet donors and returning blood donors (P<0.05). The overall ALT level (51.0 U/L), individual ALT level (56.0 U/L) and individual ALT unqualified rate (66.7%) of repeat blood donors with multiple ALT disqualifications were higher than those of repeat blood donors with single-item ALT disqualifications (26.0 U/L, 38.5 U/L, and 33.3%, respectively) (P<0.05). Moreover, as the number of ALT disqualifications increased, the overall level of ALT in repeat blood donors also increased (P<0.05), and the average level of individual ALT and individual ALT unqualified ratio tended to increase. Repeat blood donors with frequent ALT disqualifications had higher ALT levels (69.0 U/L). [Conclusion] The ALT unqualified rates of repeat blood donors were mostly non-specific elevation without TTD. Repeat blood donors with multiple ALT disqualifications tend to have continuous high ALT. Moreover, and with the increase of ALT disqualifications times, the overall ALT levels the average individual ALT levels and individual ALT unqualified rates showed an increasing trend.

[Objective] To analyze the influence of the cycle length of hepatitis B surface antigen (HBsAg) double reagent positive samples collected from voluntary blood donors in Guangzhou on the detection results. [Methods] A total of 127 044 blood samples from voluntary blood donors at Guangzhou Blood Center from August 10 to December 9, 2023 were selected. Two ELISA reagents were used for HBsAg detection, and samples with HBsAg double reagent positive and S/CO values<10 were tested continuously for 7 days to observe the changes in their S/CO values. [Results] A total of 505 HBsAg double reagent positive samples were detected, of which 52 had S/CO values less than 10. After 7 consecutive days of uninterrupted testing, the S/CO values of Wantai (median 5 decreased to 3) and Xinchuang (median 5 decreased to 3) showed an overall downward trend, and the HBsAg missed detection rate showed an upward trend (from 0 on the first day to 1/10 000 on the seventh day). A total of 13 cases had negative double reagent test results within the 7-day testing cycle. [Conclusion] With the extension of the detection cycle, the S/CO value of HBsAg detection shows a downward trend, and the missed detection rate of HBsAg shows an upward trend. Samples used for HBsAg detection should be tested promptly after sampling to improve the quality of blood testing.

Background and purpose:Urothelial carcinoma(UC)is a prevalent malignant tumor of the urinary system,and early diagnosis is crucial for improving patient prognosis.This study evaluated the diagnostic efficacy of fluorescence in situ hybridization(FISH),urine cytology and their combination for UC,as well as for its different subtypes.Methods:This study included patients who underwent transurethral resection of bladder tumor(TURBT)from January 2022 to December 2023 and approved by Ethics Commetce of Fudan Univesity Shanghai Cancer Center,No.:050432-4-2307E)that met the inclusion and exclusion criteria.We collected TURBT pathological results and pre-procedure FISH and cytology results.Diagnostic accuracy,sensitivity and specificity of FISH,cytology and their combination were analyzed and compared for urothelial carcinoma.The Strengthening the Reporting of Observational Studies in Epidemiology(STROBE)checklist and Standards for Reporting of Diagnostic Accuracy(STARD)were followed for this study.Results:A total of 283 patients were enrolled in this study,136 were diagnosed with UC,and 147 were not.Of the 136 UC cases,79(58.09%)were invasive and 57(41.91%)were non-invasive.In terms of malignancy grade,112(82.35%)were high-grade UC and 24(17.65%)were low-grade UC.Using histopathology as the gold standard,the accuracy of FISH,cytology and their combination in diagnosing UC was 79.51%,72.08%and 77.39%,respectively;sensitivity was 72.06%,58.82%and 78.68%,respectively;specificity was 86.39%,84.35%and 76.19%,respectively.The area under the curve(AUC)for FISH and the combination was similar but higher than that for cytology(0.792 vs 0.716,P=0.006;0.774 vs 0.716,P=0.004);the Net Reclassification Improvement(NRI)for FISH compared to cytology was 15.28%(P=0.006).In the 79 cases of invasive UC,FISH had higher accuracy than cytology(86.28%vs 78.32%,P=0.011).The sensitivity of FISH and the combination was higher than that of cytology(86.08%vs 67.09%,P=0.004;91.14%vs 67.09%,P＜0.001),and the AUC values were also higher(0.808 vs 0.713,P=0.004;0.784 vs 0.713,P=0.007).The NRI for FISH compared to cytology was 21.03%(P=0.003).In the 57 cases of non-invasive UC,the AUC values for all three methods were low(AUC＜0.700).Among the 112 cases of high-grade UC,FISH had higher accuracy(84.94%vs 76.45%,P=0.005),and the combination had higher sensitivity(89.29%vs 66.07%,P＜0.001)compared to cytology.The AUC values for FISH and the combination were also superior to that for cytology(0.847 vs 0.752,P=0.002;0.827 vs 0.752,P=0.001).The NRI for FISH compared to cytology was 19.01%(P=0.003).In the 24 cases of low-grade UC,the AUC values for all three methods were low(AUC＜0.600).Conclusion:For UC,particularly invasive and high-grade subtypes,FISH shows superior diagnostic efficacy compared to cytology.FISH alone offers accuracy and sensitivity comparable to the combination test,with higher specificity.In cases of non-invasive or low-grade UC,however,all three diagnostic methods demonstrate relatively low efficacy.

Starting from the inheritance and development of Chinese philosophy of life and Traditional Chinese Medicine (TCM) wisdom through the Chinese narrative medicine practice, this paper discussed the inheritance and correspondence relationship between the text reading ability in Chinese narrative medicine practice and the "four diagnostic" in TCM wisdom, narrative regulation and the "mind-body philosophy" in TCM, as well as the narrative wisdom and the "Tao produces one" in the Chinese philosophy of life. By analyzing the stories of contemporary doctors’ practice of narrative wisdom, this paper clarified that the Chinese narrative medicine system is a new model of medical education and clinical practice constructed by absorbing the essence elements of Chinese traditional life wisdom and TCM culture, and integrating the concept of western narrative medicine. It advocated for Chinese scholars to actively build the discipline of "narrative traditional Chinese medicine", constantly translate and introduce the achievements to foreign countries, and create a good narrative ecology of TCM.
