Effect of systemic lupus erythematosus on the ovarian reserve: A systematic review and meta-analysis.

OBJECTIVE: Systemic Lupus Erythematosus (SLE) is an autoimmune disease that occurs at higher rates in young women. Evidence suggests that SLE may be associated with ovarian dysfunction. Therefore, it is crucial to investigate the possible effects of SLE on ovarian reserve function. METHODS: PubMed, Embase, Web of Science, Scopus, Cochrane Library, and ClinicalTrials.gov databases were searched from inception to July 2023 to identify studies that compared ovarian reserve in patients with SLE to that of healthy individuals. The study examined anti-müllerian hormone (AMH), antral follicle count (AFC), and follicle-stimulating hormone (FSH) as outcomes. RESULTS: Thirteen studies (n=1017) were eligible for meta-analysis. Females with SLE had significantly lower levels of AMH (weighted mean difference [WMD]: -1.07, 95% confidence interval [CI]: -1.37 to -0.76, P<0.001) and AFC (WMD: -3.46, 95% CI: -4.57 to -2.34, P<0.001). There was no significant difference in FSH levels. Subgroup analyses by age of onset revealed that SLE patients with adult-onset had significantly lower AMH levels (WMD: -1.44, 95% CI: -1.71 to -1.18, P<0.001), lower AFCs (WMD: -3.11, 95% CI: -3.60 to -2.61, P<0.001) and higher FSH levels (WMD: 0.60, 95% CI: 0.15 to 1.05, P<0.01). However, SLE patients with juvenile-onset did not exhibit significant differences in their AMH and FSH levels, except for AFCs (WMD: -7.27, 95% CI: -12.39 to -2.14, P<0.01). CONCLUSION: The impact of SLE on ovarian reserve is significant, and the effect may be particularly severe in cases of adult-onset SLE.

How Does Spino-Pelvic Fixation Affect Post-Operative Compensatory Mechanisms in Adult Spinal Deformity?

STUDY DESIGN: Retrospective single-center multi-surgeon cohort study. OBJECTIVES: Compare the post-operative changes in the compensatory mechanisms of the sagittal balance according to the type of pelvic fixation: S2-Alar-iliac screws (S2AI) vs iliac screws (IS) in patients with Adult spine deformity (ASD). METHODS: ASD patients who underwent spino-pelvic fixation and remained with a PI-LL >10° mismatch post-operatively were included. Pre-operative and 1-year-follow-up PI, Lumbar lordosis (LL), pelvic tilt (PT), sacral slope (SS), thoracic kyphosis (TK), femur obliquity angle (FOA), knee flexion angle (KFA) and ankle flexion angle (AFA) were analyzed on EOS imaging. Patients were categorized based on their pelvic fixation type (S2AI vs IS), and the pre-operative to 1-year-post-operative changes (ΔX°) in the compensatory mechanisms were compared between groups. RESULTS: Patients with S2AI (n = 53) and those with IS (n = 26) screws were comparable at baseline. ΔSS averaged 9.87° in the S2AI compared to 13.2° in the IS (P = .001), whereas the ΔKFA reached 6.01° in the S2AI as opposed to 3.06° in the IS (P = .02). The ΔPT was comparable between both groups (6.35°[S2AI group] vs 5.21°[ISgroup], P = .42). ΔTK, ΔLL, ΔFOA and ΔAFA were comparable between both groups. CONCLUSION: The type of pelvic fixation impacts significantly the post-operative compensatory mechanisms in patients with ASD. Patients with S2AI screws are more likely to compensate their remaining post-operative PI-LL mismatch through their knees and less likely through their pelvis compared to patients with IS, despite similar changes in PT. This could be explained by an increased SI joint laxity in ASD patient and the lower resistance of the iliac connectors to the junctional mechanical stresses, allowing for sacro-iliac joint motion in patients with IS.

Highly Efficient Wavelength-Tunable Circularly Polarized Luminescence Film Constructed by Responsive Chiral Aggregation-induced Emission Luminophore.

Key Lab of Environment-friendly Chemistry and Circularly polarized luminescent (CPL) materials with multitudinous inherent advantages shows extensive application. In this work, we prepare a kind of highly efficient wavelength-tunable CPL free-standing films by responsive chiral aggregation-induced emission mesogen. Firstly, the pyridine-functionalized tetraphenylethene monomer (MPy) is designed and synthesized. Then, the different ration of the monomer MPy mixed with the liquid crystal (LC) reactive monomer (LC242) to fabricate a free-standing film by photopolymerization. The obtained film presents efficient CPL with a constant luminescence asymmetry factor (glum ) of +0.75, as well as sensitive wavelength tunability. Finally, this wavelength-tunable CPL film with both fluorescence and CPL modes is successfully applied in anti-counterfeiting and information encryption. This work provides a simple way to construct CPL apparatus with adjustable luminescence wavelength and high glum .

Regression of Left Ventricular Hypertrophy in Patients Combined with Peritoneal Dialysis and Hemodialysis.

Methods: This retrospective study enrolled 58 patients at The Second Affiliated Hospital of Soochow University who switched from PD to PHD. Clinical data and echocardiographic examination results were collected. Data from the two groups with a normal distribution were compared with the paired t-test. A pvalue <0.05 (two-tailed) was considered statistically significant. Results: A total of 58 subjects were enrolled, including 46 males and 12 females, with a median age of 50.2 ± 11.1 (47-68) years. The mean duration of peritoneal dialysis was 67.2 ± 33.6 months. Before and after PHD, the ultrafiltration volume (p = 0.021) and hemoglobin (p = 0.001) were increased, while SBP (p = 0.002), DBP (p = 0.002), phosphorus (p < 0.001), and ESA dosage (p < 0.001) were decreased. Before and after combined dialysis (PHD), the incidence of LVH was 76.4% and 61.8%, respectively (p = 0.013), and LVMI decreased from 173.8 ± 86.2 g/m2 to 160.6 ± 78.5 g/m2 (p < 0.001). Conclusion: Compared with PD alone, the combination of PD and HD resulted in regression of LVH and reduced LVMI.

Preliminary single-arm study of brain effects during transcutaneous auricular vagus nerve stimulation treatment of recurrent depression by resting-state functional magnetic resonance imaging.

OBJECTIVE: To examine the brain effects of transcutaneous auricular vagus nerve stimulation (taVNS) treatment of recurrent depression based on the functional brain network by using resting-state functional magnetic resonance imaging (fMRI). METHODS: Twenty-five patients with recurrent depression were enrolled in a single-arm trial of taVNS treatment for eight weeks. Clinical results were assessed by 17-item Hamilton Depression Rating Scale (HAMD-17), Hamilton Anxiety Scale (HAMA), Self-Rating Depression Scale (SDS), Self-Rating Anxiety Scale (SAS), and Ruminative Response Scale (RRS) scales. Resting-state fMRI was conducted to explore the brain effects before and after treatment. For the functional connectivity (FC) analysis, the bilateral nucleus accumbens, globus pallidus, caudate, and putamen were selected as seeds. Finally, the correlations between FC and the clinical scale scores were calculated. RESULTS: After treatment, the patients' scores of HAMD-17, HAMA, SDS, SAS, and RRS were significantly decreased ( < 0.05). FC was considerably decreased between the following areas: the left globus pallidus and the right postcentral gyrus, inferior parietal gyrus, the right globus pallidus and the left superior marginal gyrus, postcentral gyrus, superior parietal gyrus, inferior parietal gyrus, precuneus, right postcentral gyrus, superior marginal gyrus, and inferior parietal gyrus, between the right caudate and the right lingual gyrus, calcarine gyrus, and cerebellum. Changes in FC between the right globus pallidus and the left inferior parietal gyrus, between the left globus pallidus and the right postcentral gyrus were negatively correlated with HAMD-17 scores change before and after treatment (before, = 0.003, = -0.6; after, 0.009,= -0.54). The change of FC between the right globus pallidus and the right postcentral gyrus was negatively correlated with the change in SDS (= 0.026,= -0.474). The difference in FC between the right globus pallidus and the right postcentral gyrus was negatively correlated with the change in SAS (= 0.016,= -0.513). CONCLUSIONS: Recurrent depression could be effectively treated with taVNS. The changes in brain FC involving the basal ganglia, default mode, and sensorimotor networks provide insight into the effects of taVNS treatment on recurrent depression.

MiR-140 targets Wnt1 to inhibit the proliferation and enhance drug sensitivity in osteosarcoma cells.

MicroRNAs (miRNAs) have been documented to function differently in numerous human cancers. Our study planned to investigate the role of microRNA-140 (miR-140) and to identify its possible target in osteosarcoma (OS) to predict their mechanism in OS. The miR-140 was down-regulated in OS, and its high expression decreased MG63 cell proliferation. At the molecular level, Wnt1 was a target of miR-140, and its expression could be suppressed by miR-140. Besides, miR-140 overexpression decreased drug resistance in OS cells treated by doxorubicin. Collectively, overexpression of miR-140 may inhibit human OS cell proliferation and may enhance drug sensitivity by direct regulation of Wnt/ß-catenin signaling.

A randomized, parallel control and multicenter clinical trial of evidence-based traditional Chinese medicine massage treatment VS External Diclofenac Diethylamine Emulgel for the treatment of knee osteoarthritis.

BACKGROUND: Both massage and topically administered NSAIDs are safe and effective treatments for knee osteoarthritis (KOA); however, different massage technique sects in China caused assessment difficulties for the treatment of KOA. In order to standardize the massage techniques and procedures, we organized multi-disciplinary experts in China to acquire an evidence-based traditional Chinese medicine massage treatment of knee osteoarthritis. The purposes of this study will be to provide clinicians a complementary and alternative therapy for patients and to evaluate the efficacy and safety of evidence-based traditional Chinese medicine massage treatment of KOA compared to External Diclofenac Diethylamine Emulgel. METHODS AND DESIGN: A randomized controlled trial in which 300 participants diagnosed with KOA will be recruited and randomly allocated to either the experimental group or the control group in a ratio of 2:1. Two hundred participants will receive evidence-based traditional Chinese medicine massage 2 sessions per week for 10 weeks as the experimental group, and 100 participants will receive External Diclofenac Diethylamine Emulgel 3-4 times per day for 10 weeks as the control group. The patients in the two groups will receive follow-up at two time points at 5 weeks and 10 weeks from the beginning of treatment, respectively. The MRI scans and X-ray will be performed at baseline and at the end of the intervention. The primary outcome will be the changes in the Western Ontario and McMaster Osteoarthritis Index (WOMAC). Secondary outcomes will be measured by the PRO scale for knee osteoarthritis based on the concept of traditional Chinese medicine (Chinese scale for knee osteoarthritis (CSKO)), X-ray evaluation, and MRI scan evaluation. The data of WOMAC and CSKO will be analyzed at the baseline, 5 weeks, and 10 weeks from the beginning of treatment. The data from MRI scans and X-rays will be analyzed at baseline and at the end of the intervention. The significance level sets as 5%. The safety of interventions will be evaluated after each treatment session. DISCUSSION: This study will provide clinicians with much-needed knowledge for the treatment of KOA through a controlled trial. TRIAL REGISTRATION: Chinese Clinical Trial Registry ChiCTR1800014400 .

Effects of electroacupuncture on the expression of hypothalamic neuropeptide Y and ghrelin in pubertal rats with polycystic ovary syndrome.

BACKGROUND: Polycystic ovary syndrome often starts in puberty, and its pathogenesis is not clear. This study aimed to explore the pathogenesis of pubertal polycystic ovary syndrome (PCOS) and assess the therapeutic effect of electroacupuncture on pubertal PCOS. METHODS: Dihydrotestosterone (DHT) was used to induce rat models of pubertal PCOS. pubertal rats with PCOS were randomly divided into a model group (M), an electroacupuncture group (EA), and a sham acupuncture group (SA). Age-matched normal rats were regarded as normal controls (N). Rats were treated with EA or SA five times a week for 25 minutes during their 6th-7th week. At the end of the experiment, we observed any changes in ovarian morphology; detected levels of metabolic indices in serum, the hypothalamus and pancreas. RESULTS: EA significantly improved estrous cycle disorders and the ovarian polycystic morphology in pubertal rats with PCOS, but SA only improved disorders of the estrous cycle. The serum levels of insulin, neuropeptide Y(NPY) and fasting blood glucose(FBG) increased significantly (both p < 0.01), while the serum levels of ghrelin(GHRL) decreased in the model group (p < 0.01). After treatment with EA, the levels of NPY (p < 0.01) and FBG (p < 0.05) went into decrease, whereas the levels of GHRL (p < 0.05) and insulin (p < 0.01) increased. There was few differences in the hypothalamic expression of galanin (GAL), galanin-like peptide (GALP) and ghrelin receptor(GHSR) between the four groups. The upregulation of NPY mRNA and neuropeptide Y2 receptor(NPY2R) mRNA and the downregulation of GHRL protein and mRNA in the hypothalamus, and the increased expression of NPY and NPY2R as well as the decreased expression of GHRL in the arcuate nucleus (ARC) can be rescued by EA. But, surprisingly, SA seem to make no difference to the levels of FBG and insulin, and the protein expression of ghrelin in the hypothalamus and ARC. Co-expression of kisspeptin and GHSR, and co-expression of gonadotrophin releasing hormone(GnRH) and NPY2R were observed in ARC. No differences were found between groups in protein of GAL, GALP and GHRL expression in the pancreas. Neither EA nor SA can attenuate the upregulated kisspeptin protein expression in the pancreas of PCOS model rats. CONCLUSIONS: EA and SA improved the symptoms of pubertal PCOS rats, and the mechanism might be associated with regulating hypothalamic NPY and ghrelin levels.

Embedded AI system for interactive vision screen based on human action recognition.

In recent years, vision screening has emerged globally for employment (on a yearly basis) within primary and high schools since myopia heavily affects school-aged children. However, this is a laborious and time-consuming task. This article proposes an intelligent system for "self-service" vision screening. Individuals can accomplish this task independently-without any assistance by technical staff. The technical solution involved within this platform is human action recognition realized by pose estimation (real-time human joint localization in images, including detection, association, and tracking). The developed system is based on a compact and embedded artificial intelligence platform, aided by a red-green-blue-D sensor for ranging and pose extraction. A set of intuitive upper-limb actions was designed for unambiguous recognition and interaction. The deployment of this intelligent system brings great convenience for large-scale and rapid vision screening. Implementation details were extensively described, and the experimental results demonstrated efficiency for the proposed technique.

α-Pyrones with glucose uptake-stimulatory activity from the twigs of Cryptocarya wrayi.

Five new α-pyrones, cryptowratones A-E (1-5), and five known congeners (6-10), together with four other known compounds 11-14 were isolated from the twigs of Cryptocarya wrayi. The structures of the new compounds were elucidated on the basis of extensive spectroscopic data analysis and ECD calculations. All α-pyrones except 6 were evaluated for their stimulatory effects on glucose uptake in vitro with CHO-K1/GLUT4 cells. The positive control insulin displayed an approximate 42 ± 0.14% promotion on glucose uptake at 25 µM, compared with the CHO-K1/GLUT4 group. Compounds 1a/2a, 2, 3, and 10 showed a more significant stimulation of glucose uptake than insulin (25 µM) by 36 ± 0.08%, 27 ± 0.12%, 28 ± 0.12%, and 25 ± 0.12% at 1.5 µM, respectively. Immunofluorescence assays indicated the glucose uptake-stimulatory activity of α-pyrones might be correlated with increased GLUT4 translocation.

Short-term starvation synergistically enhances cytotoxicity of Niraparib via Akt/mTOR signaling pathway in ovarian cancer therapy.

BACKGROUND: Short-term starvation (STS) has gradually been confirmed as a treatment method that synergistically enhances the effect of chemotherapy on malignant tumours. In clinical applications, there are still some limitations of poly (ADP-ribose) polymerase inhibitors (PARPi), including understanding their effectiveness and side effects. Here, we sought to investigate the effect and mechanism of the combined use of STS and niraparib in the treatment of ovarian cancer. METHODS: In in vitro experiments, SKOV3 and A2780 ovarian cancer cells were treated with STS and niraparib alone or in combination. Cell viability was assessed with CCK-8, and cell cycle, apoptosis, DNA damage repair and autophagy were examined to explore the molecular mechanisms. Akt and mTOR inhibitors were used to examine any changes in DNA damage repair levels. Xenograft animal models were treated with STS and niraparib, and HE staining and immunohistochemistry were performed to examine the effects. RESULTS: The combined use of STS and niraparib inhibited cell proliferation and increased apoptosis more than niraparib application alone. In addition, compared with the niraparib group, the STS + niraparib group had increased G2/M arrest, DNA damage and autophagy, which indicated that STS pretreatment enhanced the cytotoxicity of niraparib. In animal experiments, STS did not affect the growth of transplanted tumours, but the combined treatment synergistically enhanced the cytotoxicity of niraparib. In in vivo experiments, STS did not affect the growth of transplanted tumours, but the combined treatment synergistically enhanced the cytotoxicity of niraparib and reduced the small intestinal side effects caused by niraparib chemotherapy. CONCLUSION: STS pretreatment can synergistically enhance the cytotoxicity of niraparib. STS + niraparib is a potentially effective strategy in the maintenance therapy of ovarian cancer.

[Effects of Angelicae Sinensis Radix on cAMP/Epac signaling pathway in the treatment of chronically infected cough mice with Yin deficiency syndrome].

OBJECTIVE: To investigate the effects of Angelicae Sinensis Radix (ASR) on cyclic adenosine monophosphate (cAMP) /exchange protein activated by cAMP (Epac) signaling pathway in the treatment of chronically infected cough mice with Yin deficiency syndrome. METHODS: Mice were randomly divided into blank control group, model control group, positive control group and ASR group (n=8). The chronic cough mouse model of hyperreactive and infected airway with Yin deficiency syndrome was established with fumigation (once a day, 30 days in total), lipopolysaccharide nasal drip (every 3 days 10 µl, 10 times in total), intragastric administration of thyroid gland (120 mg/kg, once a day, a total of 15 days) and inhalation of ammonia (3 min / time × 10 times). On the basis of observing eating and drinking water, body weight and autonomic activities, the effects of ASR on metabolic level, autonomous activities, antitussive effect, cell factor in bronchoalveolar lavage fluid (BALF) brain tissue 5-HT and lung tissue related active factors(SP, PGP9.5, cAMP, Epac1) were detected. RESULTS: ASR could significantly restrain cough, alleviate the pathological changes of bronchioles, reduce the contents of IL-4, IL-13, TNF-α in BALF and the levels of SP, PGP9.5, cAMP and Epac1 in lung tissues, increase the content of 5-HT in brain tissue (P＜0.05, 0.01). CONCLUSION: ASR has some effects on restraining cough and one of its mechanisms is to down-regulate cAMP/Epac signaling pathway, to alleviate airway neurogenic inflammation and reduce sensitivity of cough neural pathway.

Both compounds 1 and 2 exhibited moderate quinone reductase inducing activity in Hepa 1c1c7 cells.

Risk Factors for Anorectal Dysfunction After Interspincteric Resection in Patients With Low Rectal Cancer.

Purpose: The objective of this study was to explore the risk factors for anorectal dysfunction after intersphincteric resection in patients with low rectal cancer. Methods: A total of 251 patients who underwent intersphincteric resection from July 2014 to June 2020 were included in this study, for which the Kirwan's grade, Wexner score, and anorectal manometric index were used to evaluate the anorectal function and other parameters including demographics, surgical features, and clinical and pathological characteristics. These parameters were analysed to explore the potential risk factors for anorectal function after intersphincteric resection. Results: In the 251 included patients, 98 patients underwent partial intersphincteric resection, 87 patients underwent subtotal intersphincteric resection, and 66 patients underwent total intersphincteric resection. There were 53 (21.1%) patients who had postoperative complications, while no significant difference was observed between the three groups. Furthermore, 30 patients (45.5%) in the total intersphincteric resection group were classified as having anorectal dysfunction (Kirwan's grade 3-5), which was significantly higher than that in the partial intersphincteric resection group (27.6%) and subtotal intersphincteric resection group (29.9%). The mean Wexner score of patients that underwent total intersphincteric resection was 7.9, which was higher than that of patients that had partial intersphincteric resection (5.9, p = 0.002) and subtotal intersphincteric resection (6.4, p = 0.027). The initial perceived volume was lower in the total intersphincteric resection group than in the partial and subtotal intersphincteric resection groups at 1, 3, and 6 months after intersphincteric resection. In addition, the resting pressure, maximum squeeze pressure, and maximum tolerated volume in the total intersphincteric resection group were worse than those in the partial and subtotal groups at 3 and 6 months after intersphincteric resection. Univariate and multivariate analyses suggested that an age ≥65, total intersphincteric resection, and preoperative chemoradiotherapy were independent risk factors for anorectal dysfunction (P = 0.023, P = 0.003, and P = 0.008, respectively). Among the 66 patients who underwent total intersphincteric resection, 17 patients received preoperative chemoradiotherapy, of which 12 patients (70.6%) were classified as having anorectal dysfunction. Conclusion: The current study concluded that age ≥65, total intersphincteric resection, and preoperative chemoradiotherapy were risk factors for anorectal dysfunction after intersphincteric resection. The morbidity of anorectal dysfunction after total intersphincteric resection for patients who received preoperative chemoradiotherapy was relatively high, and the indication should be carefully evaluated.

[Effects of BiejiaYugan Granule on TGF-ß1/Smads pathway in rats with hepatic fibrosis caused by compound factors].

Objective: To investigate the therapeutic effects of Biejia Yugan Granule on hepatic fibrosis caused by compound factors in rats and its effect on TGF-ß1/Smads signaling pathway. Methods: SD rats were randomly divided into blank control group, model control group, colchicine group, Biejia Yugan Granule low, medium and high dose (1.85, 3.70, 7.40 g/kg) groups (n= 8 in each group). The rat model of hepatic fibrosis was established by treating with 5% alcohol 15 ml/kg (ig) everyday and injecting with 40% carbon tetrachloride (sc) twice a week for 42 days. The effects of Biejia Yugan Granule on liver function, liver index and water content, serum hepatic fibrosis related indicators, key proteins and gene expression of TGF-ß1/Smads signaling pathway in rats were observed. Results: Biejia Yugan Granule at the doses of 1.85, 3.70 and 7.40 g/kg could decrease the serum levels of ALT, AST, ALP and HA, PCⅢ, C-Ⅳ, LN significantly, reduce the water content of liver tissue leads to the decrease of liver index, regulate the liver tissue TGF-ß1, Smad3 mRNA and Smad7 mRNA expressions. Conclusion: Biejia Yugan Granule has obvious effects of reducing enzyme and protecting liver and inhibiting hepatic fibrosis, and inhibiting TGF-ß1/Smads signaling pathway is one of its mechanisms of anti-hepatic fibrosis.

[Effects of Butylphthalide on airway mucus hypersecretion, IL-13 and TNF-α in asthmatic mice].

Objective: To investigate the effects of Butylphthalide (NBP) on airway mucus hypersecretion, interleukin-13 (IL-13) and tumor necrosis factor-α (TNF-α) in asthmatic mice. Methods: The mice were randomly divided into control group, asthma group, DEX group and high, medium and low doses of NBP (100, 50, 25 mg/kg) groups (n=12). Ovalbumin (OVA) injection was sensitized on the 1st, 8th, and 15th day of the experiment, and OVA was inhaled on the 22nd day to stimulate for 5 weeks to replicate the asthma model, and 20 mg/kg of NBP was given for intervention before the challenge. Finally, the asthma behavior, the secretion of goblet cells and Mucin 5ac (Muc5ac)were observed, and meanwhile the viscosity of bronchoalveolar lavage fluid (BALF) and the levels of Muc5ac, IL-13 and TNF-α in BALF were measured by ELISA. Results: Compared with the control group, the degree of sneezing, nose scratching and asthma, the proliferation of airway epithelial goblet cells and secretion of Muc5ac in the asthma group were increased significantly (P＜0.01), meanwhile, the viscosity of BALF and the contents of Muc5ac, IL-13 and TNF-α were also increased significantly (P＜0.01). Compared with the asthma group, the above behavioral scores of asthma were decreased significantly (P＜0.01) after the intervention of 25, 50 and 100 mg/kg NBP, as well as the proliferation of airway epithelial goblet cells, secretion of Muc5ac, the viscosity of BALF and the contents of Muc5ac, IL-13 and TNF-α were significantly lower than those of the asthma group (P＜0.05, 0.01). Conclusion: NBP has the effect of anti-asthma by inhibiting mucus hypersecretion, and one of its mechanisms is to alleviate the abnormal expressions of IL-13 and TNF-α.

Sex-Related Outcomes of Successful Drug-Coated Balloon Treatment in De Novo Coronary Artery Disease.

PURPOSE: Although drug-coated balloon (DCB) treatment is known to be effective for de novo lesions, the influence of sex on angiographic and clinical outcomes remains unknown. This study aimed to investigate the angiographic and clinical impact of DCB treatment in patients with de novo coronary lesions according to sex. MATERIALS AND METHODS: A total of 227 patients successfully treated with DCB were retrospectively enrolled and divided into two groups according to sex. The primary endpoint was late lumen loss (LLL) at 6-month angiography, and the secondary endpoint was target vessel failure (TVF), which included cardiac death, target vessel myocardial infarction, target lesion revascularization, and target vessel thrombosis. RESULTS: The study enrolled 60 women (26.4%) and 167 men (73.6%). Compared to men, women had a smaller vessel size, larger DCB to reference vessel ratio, and more dissections after DCB treatment (55.0% vs. 37.1%, p=0.016). Women also had a significantly higher LLL compared to men (0.12±0.26 mm vs. 0.02±0.22 mm, p=0.012) at the 6-month follow-up angiography. During a median follow-up of 3.4 years (range 12.7-28.9 months), TVF was similar (women 6.7% vs. men 7.8%, p=0.944). In multivariable analysis, women were independently associated with a higher LLL. CONCLUSION: LLL was higher in women, but there was no difference in TVF between women and men. Based on multivariable analysis, the women sex was an independent predictor of higher LLL (Impact of Drug-coated Balloon Treatment in de Novo Coronary Lesion; NCT04619277).

Luminescent Liquid Crystals Based on Carbonized Polymer Dots and Their Polarized Luminescence Application.

Traditional luminescent liquid crystals (LLCs) suffer from fluorescence quenching caused by aggregation, which greatly limits their further application. In this work, a kind of novel LLCs (named carbonized polymer dot liquid crystals (CPD-LCs)) are designed and successfully synthesized through grafting the rod-shaped liquid crystal (LC) molecules of 4'-cyano-4-(4″-bromohexyloxy) biphenyl on the surface of CPDs. The peripheral LC molecules not only increase the distance between different CPDs to prevent them from aggregating and reduce intermolecular energy resonance transfer but also make this LLC have an ordered arrangement. Thus, the obtained CPD-LCs show good LC property and excellent high luminous efficiency with an absolute photoluminescence quantum yield of 14.52% in the aggregated state. Furthermore, this kind of CPD-LC is used to fabricate linearly polarized devices. The resultant linearly polarized dichroic ratio (N) and polarization ratio (ρ) are 2.59 and 0.44, respectively. Clearly, this type of CPD-LC shows promising applications for optical devices.
