Therapeutic effect of artificial liver multi-mode sequential combination in patients with hepatitis B virus-related acute-on-chronic liver failure / 中华传染病杂志

Objective:To explore the therapeutic effect of multi-mode sequential combination of artificial liver in the treatment of hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF).Methods:The clinical data of HBV-ACLF patients treated with artificial liver in Wuxi Fifth People′s Hospital from January 2018 to June 2021 were retrospectively analyzed. Eighty-six patients were divided into artificial liver multi-mode sequential combination therapy group (sequential combination group) and conventional treatment group. The cytokine level changes and model for end-stage liver disease (MELD) score were analyzed at 14 days of disease duration. The survival outcome and complications of artificial liver were analyzed after 30 days of follow-up. Two independent samples t test and chi-square test were used for statistical analysis. Cox regression analysis was used to analyze the risk factors of death, and Kaplan-Meier method was used to analyze the survival rate of patients. Results:A total of 86 patients were enrolled, including 48 patients in sequential combination group with the average number of artificial liver of 4.68 times/person, and 38 patients in conventional treatment group with the average number of artificial liver of 3.17 times/person. At 14 days of disease duration, interleukin (IL)-6, IL-8, interferon γ-inducible protein (IP)-10 level and MELD score in sequential combination group decreased significantly than those in the conventional treatment group ( t=3.80, 3.62, 4.95 and 1.11, respectively, all P<0.050). After 30 days of follow-up, 63 patients survived and 23 patients died. Cox regression analysis showed that baseline international normalized ratio (hazard ratio ( HR)=0.558, 95% confidence interval ( CI) 0.193 to 0.856, P=0.027), baseline antithrombin Ⅲ activity ( HR=0.876, 95% CI 0.824 to 0.932, P<0.001), artificial liver mode ( HR=0.819, 95% CI 0.236 to 0.992, P=0.005), spontaneous peritonitis ( HR=0.170, 95% CI 0.045 to 0.647, P=0.009) and hepatic encephalopathy ( HR=0.004, 95% CI 0.001 to 0.030, P<0.001) were independent influencing factors for 30-day survival outcome. The cumulative survival rate of sequential combination group was higher than that of conventional treatment group, and the difference was statistically significant ( χ2=5.45, P=0.020). There were no significant differences in the proportions of bleeding, deep vein thrombosis, heart rate and blood pressure instability between the two groups ( χ2=0.63, 1.20 and 0.54, respectively, all P>0.050). The platelet decline of patients in sequential combination group was slighter than that in conventional treatment group, and the difference was statistically significant ( t=-4.17, P=0.002). Conclusions:Multi-mode sequential combination therapy of artificial liver could eliminate cytokines and reduce MELD score more effectively in patients with HBV-ACLF, and prolong the survival time of patients and have little effect on platelet count.

Comparison of bond strengths of ceramic brackets bonded to zirconia surfaces using different zirconia primers and a universal adhesive

OBJECTIVES: The aim of this study is to compare the shear bond strengths of ceramic brackets bonded to zirconia surfaces using different zirconia primers and universal adhesive. MATERIALS AND METHODS: Fifty zirconia blocks (15 × 15 × 10 mm, Zpex, Tosoh Corporation) were polished with 1,000 grit sand paper and air-abraded with 50 µm Al2O3 for 10 seconds (40 psi). They were divided into 5 groups: control (CO), Metal/Zirconia primer (MZ, Ivoclar Vivadent), Z-PRIME Plus (ZP, Bisco), Zirconia Liner (ZL, Sun Medical), and Scotchbond Universal adhesive (SU, 3M ESPE). Transbond XT Primer (used for CO, MZ, ZP, and ZL) and Transbond XT Paste was used for bracket bonding (Gemini clear ceramic brackets, 3M Unitek). After 24 hours at 37°C storage, specimens underwent 2,000 thermocycles, and then, shear bond strengths were measured (1 mm/min). An adhesive remnant index (ARI) score was calculated. The data were analyzed using one-way analysis of variance and the Bonferroni test (p = 0.05). RESULTS: Surface treatment with primers resulted in increased shear bond strength. The SU group showed the highest shear bond strength followed by the ZP, ZL, MZ, and CO groups, in that order. The median ARI scores were as follows: CO = 0, MZ = 0, ZP = 0, ZL = 0, and SU = 3 (p < 0.05). CONCLUSIONS: Within this experiment, zirconia primer can increase the shear bond strength of bracket bonding. The highest shear bond strength is observed in SU group, even when no primer is used.

Do universal adhesives promote bonding to dentin? A systematic review and meta-analysis

OBJECTIVES: The aims of this study were to conduct a systematic review of the microtensile bond strength (µTBS) of multi-mode adhesives to dentin and to perform a meta-analysis to assess the significance of differences in the µTBS of one of the most commonly used universal adhesives (Scotchbond Universal, 3M ESPE) depending on whether the etch-and-rinse or self-etch mode was used. MATERIALS AND METHODS: An electronic search was performed of MEDLINE/PubMed, ScienceDirect, and EBSCOhost. Laboratory studies that evaluated the µTBS of multi-mode adhesives to dentin using either the etch-and-rinse or self-etch mode were selected. A meta-analysis was conducted of the reviewed studies to quantify the differences in the µTBS of Scotchbond Universal adhesive. RESULTS: Only 10 studies fulfilled the inclusion criteria for the systematic review. Extensive variation was found in the restorative materials, testing methodologies, and failure mode in the reviewed articles. Furthermore, variation was also observed in the dimensions of the microtensile testing beams. The meta-analysis showed no statistically significant difference between the etch-and-rinse and self-etch modes for Scotchbond Universal adhesive (p > 0.05). CONCLUSIONS: Multi-mode ‘universal’ adhesives can achieve substantial bonding to dentin, regardless of the used modes (either etch-and-rinse or self-etch).

Review: optically-triggered phase-transition droplets for photoacoustic imaging

Optically-triggered phase-transition droplets have been introduced as a promising contrast agent for photoacoustic and ultrasound imaging that not only provide significantly enhanced contrast but also have potential as photoacoustic theranostic molecular probes incorporated with targeting molecules and therapeutics. For further understanding the dynamics of optical droplet vaporization process, an innovative, methodical analysis by concurrent acoustical and ultrafast optical recordings, comparing with a theoretical model has been employed. In addition, the repeatability of the droplet vaporization-recondensation process, which enables continuous photoacoustic imaging has been studied through the same approach. Further understanding the underlying physics of the optical droplet vaporization and associated dynamics may guide the optimal design of the droplets. Some innovative approaches in preclinical studies have been recently demonstrated, including sono-photoacoustic imaging, dual-modality of photoacoustic and ultrasound imaging, and super-resolution photoacoustic imaging. In this review, current development of optically triggered phase-transition droplets and understanding on the vaporization dynamics, their applications are introduced and future directions are discussed.

Effect of Different Silane Treatments on Long-Term Bonding Between Non-Etched Glass-Ceramic and Resin Cement

he present study evaluated the bond strength between glass-ceramic and resin cement, using different silane treatments, performing no previous hydrofluoric acid (HF) etching on ceramic surface, after short- and long- term storage. One hundred and eighty glass-ceramic plaques (IPS e.max CAD®) were polished and divided into six groups (n=30) to receive different silane treatments: (1) RCP-RelyX Ceramic Primer® (one-bottle silane), (2) RCP+SB-RelyX Ceramic Primer and Adper Singlebond2® (silane plus separated adhesive), (3) SBU-Scotchbond Universal® (silane-containing universal adhesive), (4) CP-Clearfil Ceramic Primer® (silane/MDP primer), (5) NC-no-silane (negative control) and (6) PC-Previous HF etching (5%, 20s) plus RelyX Ceramic Primer® (positive control). Two resin cement cylinders (Rely X Ultimate®) were built on each plaque. Each group was divided into two sub-groups to be stored for 24 hours (24h) or 6 months (6mo) in distilled water at 37°C (n=15). Then microshear (µSBS) testing was performed. Failure mode was analyzed using scanning electron microscopy (SEM). Data were statistically analyzed by two-way ANOVA and Tukey´s test (α=0.05). Both factors and their interaction resulted statistically significant (p≤0.05). PC obtained the highest µSBS values (in MPa) at both storage times (24h: 28.11±2.44; 6mo: 19.10±3.85). After 24h storage, groups RCP+SB (10.86±3.62), SBU (8.37±4.33) and CP (8.05±3.62) were not statistically different from NC (8.00±2.51); only RCP (19.73±4.63) and PC obtained higher values. After 6 months, only PC showed higher values than NC (0.04±0.01). Cohesive failure in resin cement was more prevalent for RCP-24h and PC, while adhesive failure was more frequent among all other groups. Clinical relevance: None of the commercially available silane primers tested, improve long- term ceramic/cement bonding without performing HF etching on ceramic surface. Combination of HF acid and silane, remain as a gold standard treatment for glass-ceramic materials.

Ciento ochenta placas de cerámica (IPS e.max CAD®) fueron pulidas y divididas en 6 grupos (n=30) para ser tratadas como sigue: (1) RCPRelyX Ceramic Primer® (silano de 1 frasco), (2) RCP+SB-RelyX Ceramic Primer y Adper Singlebond2® (silano más adhesivo separado), (3) SBU-Scotchbond Universal® (adhesivo universal conteniendo silano), (4) CP-Clearfil Ceramic Primer® (primer cerámico conteniendo silano y MDP), (5) NC-ningún silano (control negativo) y (6) PC-Condicionamiento con HF previo (5%, 20s) y silano (RelyX Ceramic Primer®) (control positivo). Dos cilindros de cemento resinoso (Rely X Ultimate®) fueron construidos en cada placa. Cada grupo fue dividido en 2 sub-grupos para ser almacenados por 24 horas (24h) y 6 meses (6mo) en agua destilada a 37°C (n=15). Luego fue realizada la prueba de microcizallamiento (µSBS). El tipo de fractura fue analizado con microscopio electrónico de barrido (SEM) y los datos analizados con las pruebas estadísticas ANOVA de dos factores y Tukey (α=0.05). Ambos factores y su interacción resultaron estadísticamente significativos (p≤0.05). PC presentó los valores más altos de µSBS (MPa) para ambos tiempos de almacenamiento (24h: 28.11±2.44; 6mo: 19.10±3.85). Luego de 24h, los grupos RCP+SB (10.86±3.62), SBU (8.37±4.33) y CP (8.05±3.62) no fueron estadísticamente diferentes del grupo control negativo (NC: 8.00±2.51); sólo RCP (19.73±4.63) y PC obtuvieron resultados mayores. Después de 6 meses de almacenaje, sólo el grupo PC obtuvo valores estadísticamente mayores que NC (0.04±0.01). Fractura cohesiva en el cemento fue más prevalente para RCP-24h y PC, mientras que el tipo adhesivo fue el más frecuente para todos los demás grupos. Relevancia Clínica: Ninguno de los tratamientos de silano evaluados, mejoró significativamente la adhesión a largo plazo entre cerámica vítrea no condicionada y cemento resinoso. La combinación de HF y silano, continúa siendo el tratamiento de preferencia para cerámica vítrea durante el proceso de cementación.

Mechanism research about the role of microbleeds for early cognitive impairment in small vascular disease / 上海交通大学学报（医学版）

Objective·To make clear the role of cerebral microbleeds (CMBs) for early cognitive impairment in small vessel disease (SVD). Methods·Fifty-seven consecutive SVD patients without dementia were strictly recruited. All participants were examined with a comprehensive battery of neuropsychological tests, SWI and DTI. According to the amount of CMBs, the patients were divided into CMBs group and non-CMBs group, or divided into multiple CMBs group (CMBs ≥ 3) and non-multiple CMBs group (CMBs<3). The mean diffusivity (MD) and fractional anisotropy (FA) in periventricular, central semiovale and subcortical white matter was analyzed with a region-of-interest method. Results·The score of multiple CMBs group in attention and memory function was significantly lower than that of the non-multiple CMBs group. Correlation analysis showed that the count of CMBs in the whole brain was significantly correlated with periventricular white matter MD, subcortical white matter MD, periventricular white matter FA and subcortical white matter FA. The count of CMBs in the whole brain adjusted by age, gender, education was significantly correlated with attention/executive function. After adjustment of subcortical/ periventricular white matter FA and MD and locations of CMBs they still had significant correlation. Conclusion·CMBs can reflect the degree of destruction of white matter integrity, and have independent effects on injury of brain parenchyma, resulting in early cognitive impairment. The research also suggests the role of CMBs in cognitive impairment may exist threshold value effect.

The total effective rate of anti-hypertension in Group 1 (91.38%, 53/58) was significantly higher than that in Group 2 (74.13%, 43/58) and Group 3 (18.97%, 11/58, P<0.05 or P<0.01); and that in Group 2 was also significantly higher than that in Group 3 (P<0.01). There were significant difference in the total effective rate of CM syndrome integral in both Group 1 (93.10%, 54/58) and Group 2 (84.48%, 49/58) as compared with Group 3 (17.24%, 10/58, P<0.01), while there was no significant difference between Group 1 and Group 2 (P>0.05).</p><p><b>CONCLUSIONS</b>The multi-mode audio frequency pulse photoelectric therapeutic apparatus, combining music, laser and electric pulse stimulation, is clinically useful for grade 1 essential hypertension. This "three in one" therapy method is non-invasive, easy and simple to handle. It is expected to be popularized as a new alternative treatment.</p>

Multi-mode microwave assisted preparation of PEGylated polystyrene resin / 国际药学研究杂志

Objective: To study a method of microwave-assistant PEGylation of polystyrene resin. Methods: Modify the commercial Merrifield resin with PEG-200, and study the influence of the yield under different conditions. The self-prepared PEG resin was further derived to PEG-wang resin; kinds of amino acids were anchored, and the loading rates were compared with commercial wang resin. Result: A general series react conditions were preferred, which was performed with 5 g resin, 50 ml PEG-200. irradiating for 15 min×2 at 600 W, preset temperature was 170 °C. The resin was then transformed to PEGylated Wang resin and anchored with amino acids, the yields were satisfied. Conclusion: The multi-mode microwave assistant PEGylation of Merrifield resin method was first reported in this paper. This method has the advantages of simple operation, fast preparation, mild reaction conditions and good yield, which was much better than the traditional method.

Feasibility of multi models targeting home pain alleviation service used on 220 cases with advanced cancer / 中华流行病学杂志

Objective To investigate the feasibility and effectiveness of multiple modes on home pain alleviation service used for advanced cancer patients to in prove clinical therapy services.Methods The study was involved with 220 patients with advanced cancers to provide them with multimodal analgesia services at home,from February 2010 to February 2013.Patients in this study had been taking both opioid treatments.They were randomly devided into two groups with the number as 112 and 10g and were given different doses of morphine or other drugs.During the period of observation,data was collected under the M.D.Anderson symptom Inventory (MDASI) score and classification of score on pain.Results Differences of pain scores in the two groups and the MDASI score were significant and presented as skewed distribution.Scores on pain score were between groups were significantly different (Z=-9.735,P＜0.001).The average rankings of A group and B group were 76.68 and 162.79 respectively.Under the application of 0.4 mg alprazolam,the degree of pain alleviation seemed to be better.The differences on comprehensive scores between different drug groups were statistically significant(Z=-13.334,P＜0.001).The average rankings of groups A and B were respectively 59.87 and 179.08.Under the use of 0.4 mg of alprazolam,the results could be considered to show better improvements in symptomatic patients.Application of 0.4 mg alprazolam on patients with advanced-cancer-induced-pain showed a better symptomatic improvement than using morphine.Conclusion Patients with advanced cancers receiving multimodal analgesia short-term sedation therapies at home,showed both ideal feasibility and good effectiveness.When morphine was combined used with midazolam at home,a better outcome could be seen in pain-releasing on patients with cancer,than single morphine analgesia was used.
