Polycation–Carbon Nanohybrids with Superior Rough Hollow Morphology for the NIR-II Responsive Multimodal Therapy
Polymer–inorganic
hybrid nanomaterials have attracted much attention for the multimodal
cancer therapy, while it is still desirable to explore hybrids with
superior morphologies for two or more therapeutic modalities. In this
work, four types of carbon nanoparticles with distinct morphologies
were prepared by an elaborate template-carbonization corrosion process
and then functionalized with a similar amount of the superior polycationic
gene vector, CD-PGEA [consisting of one β-cyclodextrin core
(CD) and two cationic ethanolamine-functionalized polyÂ(glycidyl methacrylate)
(PGEA) arms] to evaluate the morphology-influenced gene and photothermal
(PT) therapy. Benefiting from the starting rough hollow nanosphere
(RHNS) core, the resultant nanohybrids RHNS-PGEA exhibited the highest
gene transfection (including luciferase, fluorescent protein plasmid,
and antioncogene p53) and NIR PT conversion efficiency among the four
types of nanohybrids. Moreover, the efficient PT effect endowed RHNS-PGEA
with PA imaging enhancement and an effective imaging guide for the
tumor therapy. In addition, anticancer drug 10-hydroxy camptothecin
was successfully encapsulated in RHNS with polycation coating, which
also displayed the second near-infrared (NIR-II)-responsive drug release.
Taking advantages of the superior gene delivery/PT effect and NIR-II-enhanced
drug delivery, RHNS-PGEA realized a remarkable therapeutic effect
of trimodal gene/PT/chemotherapy of malignant breast cancer treatment
in vitro and in vivo. The present work offers a promising approach
for the rational design of polymer–inorganic nanohybrids with
superior morphology for the multimodal cancer therapy

DataSheet_1_Clinicopathological and prognostic characteristics of idiopathic membranous nephropathy with dual antigen positivity.docx
BackgroundIdiopathic membranous nephropathy (IMN) is the most common pathological type in adults with nephrotic syndrome. Many target antigens have been discovered. However, dual antigen-positive IMN patients are very rare, with only a few such cases being briefly described in various studies. There is no specific study on the clinicopathological and prognostic characteristics of dual antigen-positive IMN patients, and the disease characteristics of such patients remain unclear.MethodsImmunohistochemical staining of PLA2R, THSD7A, and NELL-1 was conducted on kidney tissue samples obtained from patients diagnosed with IMN. Simultaneously, the presence of corresponding serum antibodies was determined. Patients exhibiting positivity for dual antigens were included in the study, identified either through tissue staining or serum antibody detection. We retrospectively collected their clinical, pathological, and follow-up data and measured their serum antibody levels at multiple time points. Additionally, the same type of dual antigen-positive IMN cases reported in the literature were reviewed to extract clinical, pathological, and prognostic information. We compared the data for all of the above dual antigen-positive and PLA2R single-positive IMN cases at our center.ResultsWe identified 6 IMN patients with dual antigen positivity at our center, approximately 0.7% of whole MN series; the previous literature reports 43 IMN patients with dual antigen positivity, the proportion ranged from 0.2% to 2.8%. The IgG1 positivity rate in the renal tissue of the dual antigen-positive patients at our center was significantly lower than that of dual antigen-positive patients previously reported (16.7% vs. 100.0%, p=0.015), but there was no significant difference in clinical or prognostic aspects. Patients with dual antigen positivity reported at our center and in the literature were combined and compared with PLA2R single-positive IMN reported at our center. Compared with PLA2R single-positive IMN patients, dual antigen-positive IMN patients had a higher renal tissue IgG1 positivity rate (58.3% vs. 22.3%, p=0.016), and the time required to achieve remission was longer [13.5 (3.3,35.0) vs. 3.0 (1.0,8.0), p=0.052]. Overall, The changes in urine protein were consistent with the changes in serum PLA2R antibody levels in dual antigen-positive IMN patients.ConclusionsFor patients with primary membranous nephropathy who did not attain remission following prolonged treatment, multiple target antigen staining should still be actively performed, even with positivity for the PLA2R target antigen.</p

Association between extreme temperature and acute myocardial infarction hospital admissions in Beijing, China: 2013–2016
Over the past few decades, a growing body of epidemiological studies found the effects of temperature on cardiovascular disease, including the risk for acute myocardial infarction (AMI). Our study aimed to investigate whether there is an association between extremely temperature and acute myocardial infarction hospital admission in Beijng, China. We obtained 81029 AMI cases and daily temperature data from January 1, 2013 to December 31, 2016. We employed a time series design and modeled distributed lag nonlinear model (DLNM) to analyze effects of temperature on daily AMI cases. Compared with the 10th percentile temperature measured by daily mean temperature (Tmean), daily minimum temperature (Tmin) and daily minimum apparent temperature (ATmin), the cumulative relative risks (CRR) at 1st percentile of Tmean, Tmin and ATmin for AMI hospitalization were 1.15(95% CI: 1.02, 1.30), 1.24(95% CI: 1.11, 1.38) and 1.41(95% CI: 1.18, 1.68), respectively. Moderate low temperature (10th vs 25th) also had adverse impact on AMI events. The susceptive groups were males and people 65 years and older. No associations were found between high temperature and AMI risk. The main limitation of the study is temperature exposure was not individualized. These findings on cold-associated AMI hospitalization helps characterize the public health burden of cold and target interventions to reduce temperature induced AMI occurrence.</div
