Background/Aims: This study aimed to assess the impact of INTERCEPT Foam Spray (IFS) application on delayed endoscope reprocessing through microbiological surveillance culture (MSC). Methods: A quasi-experimental, matched-comparison pilot study was conducted using gastrointestinal endoscopy. IFS was applied to the endoscopes after precleaning and before reprocessing the next day. An equal number of endoscopes, matched by endoscope type, were subjected to routine reprocessing. The MSC were subjected to high-level disinfection to detect any contamination. Data were analyzed using the chi-square test or Fisher exact test (categorical data) and Student t-test (continuous data). Results: In total, 150 MSCs were collected from 42 endoscopes. Positive MSCs were observed in 4.0% (4/75) of the sprayed group and 1.3% (1/75) of the control group (95% confidence interval, 30.34–0.31; p>0.05), all of which were contributed by colonoscopes. Colonoscope were more prone to positive MSC (mean difference in percentage, p<0.05). Mean spraying hours were not associated with detected growth (11.7% vs. 13.6%; 95% confidence interval, 1.43 to –5.27; p>0.05), with environmental and skin flora being the primary contaminants. Conclusions IFS may be applied when delayed endoscope processing is necessary, but with caution when applied to colonoscopes. However, further research is warranted to verify the result.

Objective:To evaluate the distribution characteristics of choroidal vascularity index (CVI) in macula among normal children using swept-source optical coherence tomography (SS-OCT), and to investigate the influencing factors.Methods:A cross-sectional study was conducted.Sixty-three children aged 6 to 12 years were enrolled in The First Affiliated Hospital of Zhengzhou University from May 2021 to November 2021.Spherical equivalent refraction, axial length (AL) and other ocular biological parameters were measured.Macula-centered CVI and choroidal thickness (ChT) were measured by SS-OCT angiography.According to the ETDRS partition, the obtained image was divided into macular central fovea (0-1 mm diameter), inner ring (1-3 mm diameter) and outer ring (3-6 mm diameter) zones.Data from the right eye were selected for statistical analysis.CVI in the three rings and four zones (superior, temporal, inferior and nasal zones) of the inner and outer rings were compared.Univariate and multiple linear regression analyses were used to analyze the correlation between CVI and sex, AL, anterior chamber depth (ACD), ChT and pupil diameter.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of The First Affiliated Hospital of Zhengzhou University (No.2021-KY-0399-003). Written informed consent was obtained from each guardian.Results:The average CVI in the macular central fovea, inner ring and outer ring were 0.35±0.12, 0.32±0.10 and 0.27±0.08, respectively, with a significant difference ( F=10.96, P<0.001), and significant differences in CVI were found in pairwise comparisons of the three ring zones (all at P<0.05). Significant differences in CVI were found among superior, temporal, inferior and nasal zones in inner and outer rings ( Fring=11.60, P=0.001; Fzone=12.02, P<0.05). The CVI was smaller in superior and nasal zones in inner ring than in temporal zone, greater in superior, temporal and inferior zones in outer ring than in nasal zone, smaller in superior zone of outer ring than that of the inner ring, and the differences were statistically significant (all at P<0.001). The single factor linear regression analysis showed that ChT in the fovea, inner ring and outer ring were the influencing factors of CVI in the three ring zones (all at β=0.001, P<0.001). Pupil diameter ( β=0.034, P=0.038; β=0.040, P=0.003; β=0.024, P=0.011) and ACD ( β=0.097, P=0.034; β=0.097, P=0.013; β=0.061, P=0.032) were the influencing factors of CVI in fovea, inner ring and outer ring.After multiple linear regression analysis, the regression equations were established as follows: CVI in the macular fovea=0.001×ChT in the macular fovea + 0.001×ChT in the inner ring+ 0.001×ChT in the outer ring-0.301 ( R2=0.514, F=6.875, P<0.001); CVI in the inner ring=0.001×ChT in the macular fovea+ 0.001×ChT in the inner ring+ 0.001×ChT in the outer ring+ 0.088×AL-0.307 ( R2=0.603, F=9.870, P<0.001); CVI in the outer ring=0.001×ChT in the macular fovea+ 0.001×ChT in the inner ring+ 0.001×ChT in the outer ring-0.135 ( R2=0.601, F=9.781, P<0.001). Conclusions:In children aged 6-12 years old, the CVI is higher in the macular central fovea than in inner and outer rings, and the CVI in nasal zone is the smallest in both inner and outer rings.The thicker the ChT, the higher the CVI in all zones in the macular area; the deeper the anterior chamber, the higher the CVI in the inner ring.

Proteomic characterization of plasma is critical for the development of novel pharmacodynamic bio-markers.However,the vast dynamic range renders the profiling of proteomes extremely challenging.Here,we synthesized zeolite NaY and developed a simple and rapid method to achieve comprehensive and deep profiling of the plasma proteome using the plasma protein corona formed on zeolite NaY.Specifically,zeolite NaY and plasma were co-incubated to form plasma protein corona on zeolite NaY(NaY-PPC),followed by conventional protein identification using liquid chromatography-tandem mass spectrometry.NaY was able to significantly enhance the detection of low-abundance plasma proteins,minimizing the"masking"effect caused by high-abundance proteins.The relative abundance of middle-and low-abundance proteins increased substantially from 2.54％to 54.41％,and the top 20 high-abundance proteins decreased from 83.63％to 25.77％.Notably,our method can quantify approxi-mately 4000 plasma proteins with sensitivity up to pg/mL,compared to only about 600 proteins iden-tified from untreated plasma samples.A pilot study based on plasma samples from 30 lung adenocarcinoma patients and 15 healthy subjects demonstrated that our method could successfully distinguish between healthy and disease states.In summary,this work provides an advantageous tool for the exploration of plasma proteomics and its translational applications.

Cell pyroptosis is a programmed death of inflammatory cells. Many members of the gasdermin family （the effector protein family that forms pores） participate in the pathological process of a variety of diseases， such as cancer， myocardial ischemia， renal injury， and osteoarthritis， mainly by activating cysteine aspartate-specific protease （Caspase） for polymerization and shear. Cell pyroptosis has bidirectional regulation. Induction of pyroptosis can promote cell clearance under pathological conditions （such as cancer and tumor cells）， but long-term induction of pyroptosis can lead to abnormal lipid and related vitamin metabolism in vivo. Regulating the balance between cell pyroptosis and proliferation is an important target for traditional Chinese medicine （TCM） treatment of diseases. The Yin-Yang theory runs through the whole process of TCM diagnosis and treatment， which is used to explain the physiological and pathological changes of human body and guide the theory， diagnosis and treatment of diseases and health care. The balance between cell proliferation and pyroptosis is essentially the embodiment of Yin-Yang balance at the cellular level， and the theory of Yin-Yang spontaneous harmonization dominates the balance. TCM intervention on cell pyroptosis is mainly reflected in promoting and inhibiting cell pyroptosis， which has the same significance as Yin-Yang regulation. Based on this theory， this paper revealed the relationship between TCM inhibiting and promoting cell pyroptosis through the Yin-Yang theory， to provide theoretical support for the modernization of the Yin-Yang theory and new goals for the diagnosis and treatment of diseases.

Objective:To observe the safety and efficacy of 0.01% atropine eye drops in the prevention of myopia onset in schoolchildren.Methods:A randomized double-blind controlled study was conducted.Sixty Chinese Han children (60 eyes) with binocular spherical equivalent (SE) between + 0.50 D and -0.75 D (pre-myopia) by cycloplegic autorefraction treated in The First Affiliated Hospital of Zhengzhou University were enrolled from July to October 2020.Aged 6-12 years old, the children were divided into 0.01% atropine group and control group according to a random number table, with 30 cases (30 eyes) in each group.The children were given one drop of 0.01% atropine or placebo eye drops in both eyes once a night.The SE, axial length (AL), accommodative amplitude and pupil diameter were compared before and after 3-month, 6-month of treatment between the two groups.Discomforts were recorded.This study adhered to the Declaration of Helsinki.The study protocol was approved by an Ethics Committee of The First Affiliated Hospital of Zhengzhou University (No.2020-KY-286). Written informed consent was obtained from guardian of each subject.Results:After treatment, 26 and 25 subjects completed the 6-month follow-up in 0.01% atropine group and control group, respectively, among which 3 subjects in 0.01% atropine group accounting for 11.5% and 9 in control group accounting for 36.0% developed myopia, showing a statistically significant difference ( χ2=4.238, P=0.040). There were significant differences in the overall comparison of SE and AL at different time points between before and after treatment ( Ftime=10.981, 81.854; both at P<0.001). At 3 and 6 months after treatment, there were significant increases in the SE and AL of control group and AL of 0.01% atropine group compared with respective baseline values (all at P<0.05). There was no significant difference in SE at 3 and 6 months after treatment compared with baseline SE in 0.01% atropine group (both at P>0.05). At 6 months after treatment, the change in SE in 0.01% atropine group was (-0.15±0.26)D, which was significantly less than (-0.34±0.35)D in control group, and the change in AL in 0.01% atropine group was (0.17±0.11)mm, Which was significantly shorter than (0.28±0.14)mm in control group, with significant differences between them ( t=2.207, P=0.032; t=3.127, P=0.003). There were significant differences in pupil diameter at different time points between before and after treatment ( Ftime=2.263, P=0.032). At 3 and 6 months after treatment, the pupil diameter was increased in comparison with baseline in 0.01% atropine group (both at P<0.05). There were significant differences in accommodative amplitude at different time points between before and after treatment in the two groups ( Fgroup=0.882, P=0.042; Ftime=0.337, P=0.033). The accommodative amplitude at 3 and 6 months after treatment were decreased in comparison with baseline in 0.01% atropine group and control group at corresponding time points (all at P<0.05). Within a month after treatment, photophobia in bright sunlight occurred in 5 cases in 0.01% atropine group, accounting for 16.7%(5/30), and 2 cases in control group, accounting for 6.7%(2/30), showing no significant difference ( χ2=0.647, P=0.421). No near-vision blur and other uncomfortable symptoms was found in the two groups. Conclusions:After 6-month application of 0.01% atropine eye drops, the prevalence of myopia in pre-myopia schoolchildren decreases and the changing rate of SE and AL slows down.The accommodative amplitude is slightly reduced and pupil diameter is slightly increased, with no obvious effects on study and life.
