Peptide receptor radionuclide therapy (PRRT) with radiolabeled SSTR2 agonists is a treatment option that is highly effective in controlling metastatic and progressive neuroendocrine tumors (NETs). Previous studies have shown that an SSTR2 agonist combined with albumin binding moiety Evans blue (denoted as 177Lu-EB-TATE) is characterized by a higher tumor uptake and residence time in preclinical models and in patients with metastatic NETs. This study aimed to enhance the in vivo stability, pharmacokinetics, and pharmacodynamics of 177Lu-EB-TATE by replacing the maleimide-thiol group with a polyethylene glycol chain, resulting in a novel EB conjugated SSTR2-targeting radiopharmaceutical, 177Lu-LNC1010, for PRRT. In preclinical studies, 177Lu-LNC1010 exhibited good stability and SSTR2-binding affinity in AR42J tumor cells and enhanced uptake and prolonged retention in AR42J tumor xenografts. Thereafter, we presented the first-in-human dose escalation study of 177Lu-LNC1010 in patients with advanced/metastatic NETs. 177Lu-LNC1010 was well-tolerated by all patients, with minor adverse effects, and exhibited significant uptake and prolonged retention in tumor lesions, with higher tumor radiation doses than those of 177Lu-EB-TATE. Preliminary PRRT efficacy results showed an 83% disease control rate and a 42% overall response rate after two 177Lu-LNC1010 treatment cycles. These encouraging findings warrant further investigations through multicenter, prospective, and randomized controlled trials.

Objective:To investigate the value of systemic inflammatory response syndrome (SIRS), pediatric sequential organ failure assessment (pSOFA) and pediatric critical illness score (PCIS) in predicting mortality of pediatric sepsis in pediatric intensive care units (PICU) from Southwest China.Methods:This was a prospective multicenter observational study. A total of 447 children with sepsis admitted to 12 PICU in Southwest China from April 2022 to March 2023 were enrolled. Based on the prognosis, the patients were divided into survival group and non-survival group. The physiological parameters of SIRS, pSOFA and PCIS were recorded and scored within 24 h after PICU admission. The general clinical data and some laboratory results were recorded. The area under the curve (AUC) of the receiver operating characteristic curve was used to compare the predictive value of SIRS, pSOFA and PCIS in mortality of pediatric sepsis.Results:Amongst 447 children with sepsis, 260 patients were male and 187 patients were female, aged 2.5 (0.8, 7.0) years, 405 patients were in the survival group and 42 patients were in the non-survival group. 418 patients (93.5%) met the criteria of SIRS, and 440 patients (98.4%) met the criteria of pSOFA≥2. There was no significant difference in the number of items meeting the SIRS criteria between the survival group and the non-survival group (3(2, 4) vs. 3(3, 4) points, Z=1.30, P=0.192). The pSOFA score of the non-survival group was significantly higher than that of the survival group (9(6, 12) vs. 4(3, 7) points, Z=6.56, P<0.001), and the PCIS score was significantly lower than that of the survival group (72(68, 81) vs. 82(76, 88) points, Z=5.90, P<0.001). The predictive value of pSOFA (AUC=0.82) and PCIS (AUC=0.78) for sepsis mortality was significantly higher than that of SIRS (AUC=0.56) ( Z=6.59, 4.23, both P<0.001). There was no significant difference between pSOFA and PCIS ( Z=1.35, P=0.176). Platelet count, procalcitonin, lactic acid, albumin, creatinine, total bilirubin, activated partial thromboplastin time, prothrombin time and international normalized ratio were all able to predict mortality of sepsis to a certain degree (AUC=0.64, 0.68, 0.80, 0.64, 0.68, 0.60, 0.77, 0.75, 0.76, all P<0.05). Conclusion:Compared with SIRS, both pSOFA and PCIS had better predictive value in the mortality of pediatric sepsis in PICU.

ObjectiveTo observe the effect of water extract of Mori Folium (MLE) on oxidative stress in adipose tissue of type 2 diabetes mellitus (T2DM) mice and explore its mechanism. MethodTwenty-four male db/db mice were randomly divided into model group, metformin group, low-dose MLE (MLE-L) group, and high-dose MLE (MLE-H) group according to their body weight and blood glucose, with six mice in each group, and other six C57BLKS/JGpt wild littermate mice were selected as normal group. The mice in the metformin group were given 200 mg·kg-1 metformin suspension, and the mice in the MLE-L and MLE-H groups were respectively given 2 g·kg-1 and 4 g·kg-1 MLE, while the mice in the normal group and model group were given the same dose of deionized water by daily gavage for eight weeks. Body weight, subcutaneous fat index, fasting blood glucose (FBG), and oral glucose tolerance level (OGTT) of the mice were detected, and serum superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and malondialdehyde (MDA) were measured. The expression levels of silent information regulator 1 (SIRT1) and NADPH oxidase type 4 (NOX4) protein in subcutaneous adipose tissue of the mice were detected by Western blot. ResultThe FBG level, OGTT, and subcutaneous fat index of T2DM mice were significantly decreased (P<0.05, P<0.01) after administration of MLE compared with the blank group. The contents of serum SOD and GSH were significantly increased, while the level of oxidative stress damage marker MDA was significantly decreased (P<0.05, P<0.01). The expression of SIRT1 protein in adipose tissue was significantly increased, while the expression of NOX4 protein was significantly decreased (P<0.05, P<0.01). ConclusionMLE can ameliorate T2DM by alleviating oxidative stress in adipose tissue of T2DM mice and reducing blood glucose.

ObjectiveTo investigate the protective effects of Mori Folium extract (MLE) on the kidney of db/db diabetic mice and its mechanism. MethodTwenty-four male C57BLKS/JGpt-Leprdb/Leprdb (db/db) mice were randomly divided into model group, metformin group, low-dose group of MLE (MLE-L), and high-dose group of MLE (MLE-H) according to their fasting blood glucose (FBG), with six mice in each group, and other six C57BLKS/JGpt wild littermate (m/m) mice were selected as normal group. The mice in the drug administration groups were given corresponding drugs by gavage, and the mice in the normal group and model group were given the same dose of deionized water by gavage once a day for continuous eight weeks. Body weight, bilateral kidney weight, and FBG were measured, and an oral glucose tolerance test (OGTT) was performed. The pathological changes in the kidney tissue of mice were observed by hematoxylin-eosin (HE) and periodic acid-silver (PAS) staining, and serum creatinine (SCr) and blood urea nitrogen (BUN) levels were detected. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) in serum and urinary microalbumin (U-mAlb) of mice. The expression levels of toll-like receptor 4 (TLR4), myeloid differentiation factor 88 (MyD88), and nuclear factor-kappa B p65 (NF-κB p65) protein in kidney tissue of mice were tested by Western blot. ResultCompared with the normal group, the body weight, absolute renal weight, FBG, and the area under the curve (AUC) of OGTT of mice in the model group were significantly increased (P<0.01), and the levels of SCr, BUN, and U-mAlb, as well as TNF-α and IL-6 in serum were significantly increased (P<0.01). The glomerular basement membrane in the kidney tissue of mice was thicker, with obvious inflammatory cell infiltration. The protein expression levels of TLR4, MyD88, and NF-κB p65 in the kidney tissue of mice were increased significantly (P<0.01). Compared with the model group, there was no statistical difference in the body weight of mice in each drug administration group. The absolute renal weight of mice in the MLE-H and metformin groups was significantly reduced (P<0.05, P<0.01). The FBG levels of mice in the metformin, MLE-L, and MLE-H groups started to decrease after treatment for four to eight weeks (P<0.05, P<0.01). The AUC of mice in the MLE-H and metformin groups was significantly decreased (P<0.01). The levels of SCr, BUN, and U-mAlb of mice in the MLE-H and metformin groups were significantly decreased (P<0.01), and those of SCr and U-mAlb of mice in the MLE-L group were significantly decreased (P<0.01). The levels of TNF-α and IL-6 in the serum of mice in the MLE-H and metformin groups were significantly decreased (P<0.01). The renal tissue pathology of mice in each drug administration group was improved to varying degrees, and the protein expression levels of TLR4, MyD88, and NF-κB p65 in the MLE-H group were decreased significantly (P<0.05, P<0.01). ConclusionMLE can improve the renal structure and function of db/db diabetic mice, and its mechanism may be related to the inhibition of the TLR4/MyD88/NF-κB signaling pathway.

Mori Folium, the dried leaves of Morus alba, is widely used in clinical practice for dispersing wind and heat, clearing the lung and moistening dryness, soothing the liver and improving vision, and cooling blood and stopping bleeding. It has been used to regulate blood glucose since ancient times, and modern studies have shown that the active components of Mori Folium for lowering blood glucose mainly include flavonoids, alkaloids, polysaccharides, and phenols. These components are mainly extracted by solvents such as water and alcohols with the assistance of ultrasound and microwave. In addition, new extraction methods are emerging, such as CO2 supercritical fluid extraction, enzymatic hydrolysis, and cloud point extraction. Mori Folium lowers blood glucose via multiple components, pathways, and targets. Specifically, it can improve glucose and lipid metabolism, protect pancreatic β cells, and alleviate insulin resistance to reduce the damage caused by hyperglycemia and restore normal physiological functions. Although a large number of studies have been carried out on diabetes, the causes and radical treatment methods remain to be explored, and diabetes is still a major disease that endangers human health and needs to be solved urgently. The articles about extraction process and mechanism of active components in Mori Folium for lowering blood glucose were retrieved from the China National Knowledge Infrastructure (CNKI), Web of Science, and PubMed. We analyzed the applicable extraction methods for the blood glucose-lowering components such as flavonoids, polysaccharides, and alkaloids in Mori Folium, and compared the conventional and emerging methods. Furthermore, we summarized our research achievements in the extraction of active components from Mori Folium and the blood glucose-lowering effect and mechanisms. This review aims to provide theoretical support for the optimization of the extraction process, the research on the blood glucose-lowering components and mechanism, and the development of new drugs and clinical application of Mori Folium.

【Objective】 To investigate the differences in efficacy and long-term prognosis between locally progressive low and intermediate rectal cancer patients receiving fluorouracil-based neoadjuvant chemotherapy alone (mFOLFOX6/CapeOX) and neoadjuvant radiotherapy, and to compare the therapeutic efficacy in the two groups. 【Methods】 We retrospectively analyzed the clinicopathological data of 118 patients with locally progressive low and intermediate rectal cancer who received neoadjuvant therapy from January 2019 to December 2021 at The First Affiliated Hospital of Xi’an Jiaotong University, including gender, age, body mass index (BMI), and other clinicopathological parameters. The t-test, Mann Whitney test, chi-square test or Fisher’s exact test were used to compare the differences between the two groups of patients who received neoadjuvant chemotherapy alone or neoadjuvant radiochemotherapy in terms of short-term efficacy, lymph node manifestations and long-term prognosis, respectively. Survival rates were calculated and survival curves were plotted using the Kaplan-Meier method. 【Results】 In terms of efficacy, patients in the neoadjuvant radiotherapy group achieved better tumor regression (Z=-2.05, P=0.04) and solid tumor efficacy (Z=-2.42, P=0.015), but the difference between the two groups in terms of downstaging effect of clinical stage was not statistically significant. The number of lymph nodes detected was significantly lower in the neoadjuvant radiotherapy group (neoadjuvant chemotherapy vs. neoadjuvant radiochemotherapy, 13.19±3.83 vs. 9.55±4.00, t=5.02, P<0.001), but the two groups did not differ significantly in the number of lymph node positives and lymph node positive ratio. In terms of long-term prognosis, there was no statistically significant difference in the overall survival rate or disease-free survival rate of the two groups. 【Conclusion】 Compared with neoadjuvant chemotherapy alone, neoadjuvant radiotherapy showed better short-term efficacy in patients with locally progressive low and intermediate rectal cancer, but there was no statistically significant difference between the two treatment regimens in terms of long-term prognosis.

Objective:A genome-wide molecular characterization of FJ21351116, a strain of G3P[8]-E2 2021 collected in Fujian, China, was performed.Methods:Whole genome sequencing of FJ21351116 was performed using a high-sensitivity group A rotavirus whole genome sequencing method. Genomic characteriza-tion of the virus was assessed by nucleic acid sequence analysis using MEGA 11.0, Geneious 9.0.2 and DNASTAR software. Neutralization epitopes of VP7 and VP4 (VP8*) were analyzed using BioEdit v. 7.0.9.0 and PyMOL v. 2.5.2.Results:In this study, FJ21351116 was shown to be a G3-P[8]-I2-R2-C2-M2-A2-N2-T2-E2-H2 genotype, and the result of phylogenetic tree showed that the VP7, VP4, VP3, and NSP2-NSP5 genes of the FJ21351116 strain were related to the equine-like DS-1-like G3P[8] genes that have been detected in Japan in recent years. VP6, VP1, VP2, and NSP1 genes are closely related to G2P[4] in most countries, especially in Singapore, suggesting that this strain was formed by genetic reassortment during the evolution of equine-like G3P[8] and G2P[4]. Evolutionary relationships between the VP7/VP4 genes of FJ21351116 and Rotarix and RotaTeq vaccines suggest that the multiple mutations in both VP7 and VP4 (VP8*) neutralizing antigenic epitopes and vaccine amino acid sites. It is hypothesized that the Rotarix and RotaTeq vaccines may be less effective against equine DS-1-like G3P[8] RVA, and the sequence differences with Rotarix are higher than those with RotaTeq.Conclusions:In this study, we found a rare case of DS-1-like G3P [8] RVA strain in China. Currently, horse-like DS-1-like G3P [8] RVA is relatively rare in China and may be poorly protected by vaccine strains, emphasizing the importance of continuous monitoring of RVA strains and the development of efficient and full-coverage RVA vaccines.
