Anti-tumor traditional Chinese medicine has a long history of clinic application, in which the star molecules have always been the hotspot of modern drug research, but they are limited by the solubility, stability, targeting, bioactivity or toxicity of the monomer components of traditional Chinese medicine anti-tumor star molecules and other pharmacokinetic problems, which hinders the traditional Chinese medicine anti-tumor star molecules for further clinical translation and application. Currently, the nanosystems prepared by supramolecular technologies such as molecular self-assembly and nanomaterial encapsulation have broader application prospects in improving the anti-tumor effect of active components of traditional Chinese medicine, which has attracted extensive attention from scholars at home and abroad. In this paper, we systematically review the research progress in preparation of supramolecular nano-systems from anti-tumor star molecule of traditional Chinese medicine, and summarize the two major categories and ten small classes of carrier-free and carrier-based supramolecular nanosystems and their research cases, and the future development direction is put forward. The purpose of this paper is to provide reference for the research and clinical transformation of using supramolecular technology to improve the clinical application of anti-tumor star molecule of traditional Chinese medicine.

Objective:To investigate the characteristics of executive function of preschool children with high functioning autism spectrum disorder (HFA) and with global developmental delay (GDD), and the differences among HFA, GDD and typically developmental (TD) children.Methods:From January 2020 to January 2021, 20 male HFA, 20 male GDD and 20 male TD children aged 4-6 years who visited the Psychological Behavior Clinic of the Child Health Department of Guiyang Maternal and Child Health Hospital and the Developmental Behavior Clinic of the Children Health Department of the Ninth People's Hospital in Chongqing were selected for comparative study.The executive function of HFA, GDD and TD children was assessed with the behavior rating scale of executive function-preschool version(BRIEF-P) and the executive function task program (EF-TOUCH). SPSS 26.0 software was used for statistical analysis, including variance test, independent sample t-test, χ2 test, Kruskal Wallis test and Mann-Whitney U test. Results:In the EF-TOUCH program task, the accuracy of the three groups of children's performance in the pig task (Pig), the silly sounds game (SSG), the working memory task (pick the picture, PTP) and the task of cognitive flexibility (something's the same, STS) were statistically different(Pig: HFA group: 0.87(0.76, 0.99), GDD group: 0.97(0.85, 0.99), TD group: 1.00(0.98, 1.00), χ2=15.646, P<0.001; SSG: HFA group: 0.76(0.53, 0.91), GDD group: 0.76(0.65, 0.99), TD group: 0.94(0.76, 1.00), χ2=6.448, P=0.040; PTP: HFA group: 0.66±0.18, GDD group: 0.66±0.19, TD group: 0.78±0.11; F=3.221, P=0.048; STS: HFA group: 0.67(0.63, 0.70), GDD group: 0.72(0.46, 0.78), TD group: 0.87(0.83, 0.90), χ2=26.898, P<0.001). The accuracies of Pig, SSG, PTP and STS in HFA group were significantly lower than those in TD group(all P<0.05), and the accuracies of Pig and STS in GDD group were significantly lower than those in TD group(both P<0.05). In inhibition control, there were statistically differences in response time of Pig and SSG among the three groups (Pig: HFA group: (1 694.36±222.83)ms, GDD group: (1 513.46±244.91)ms, TD group: (1 444.84±197.95)ms, F=5.810, P=0.005; SSG: HFA group: (2 202.42±195.58)ms, GDD group: (2 116.52±323.27)ms, TD group: (1 937.17±252.74)ms, Z=4.610, P=0.014). There were no significant differences in the reaction time of Arrows task ( P>0.05). There were significant differences in BRIEF-P inhibition control, organizational planning, inhibition self-regulation, cognitive flexibility and total scores among the three groups ( P<0.05), while there were no significant differences in the scores of other factors and dimensions ( P>0.05). Conclusion:The executive function of pre-school children with high functioning autism spectrum disorder and children with global developmental delay is impaired.The executive function of children with high functioning autism spectrum disorder and children with global developmental delay is significantly different from that of typically developmental children of the same age.Moreover, the executive function of children with HFA is more severely damaged from all components than that of children with GDD.

Objective: To analyze the immunological characteristics and antibody changes of patients infected with the Omicron BA.1 and evaluate the possibility of secondary infection. Methods: A total of 104 patients infected with Omicron BA.1 in the Jinnan District of Tianjin from January 8 to February 2, 2022, were included in the study. The control group and case group were matched 1∶1 based on age, sex and vaccination status. Serum was collected from the case group and control group at 3, 6 and 9 months after infection. The serum levels of interleukin4 (IL-4), IL-5 and interferon-gamma (IFN-γ), as well as the positive rates of IgG, IgG1 and IgG2, were detected by ELISA. Results: The highest concentration of IFN-γ in the case group at 6 months after infection was 145.4 pg/ml, followed by a decrease in concentration. The concentrations of IL-4 and IL-5 began to decrease at 6 months after infection (all P<0.001). There was no significant difference in the IgG2 positive rate between the case group and the control group at 6 months after BA.1 infection. However, at 9 months, there was a significant decrease compared to the control group (P=0.003). The ratio of IFN-γ/IL4 at 3 months after infection in the case group was lower than that in the control group (P<0.001). There was no significant difference in the ratio between the case group and the control group at 9 months after infection. Conclusion: The cellular immune function has been impaired at 3 months after infection with BA.1, and the specific cellular immune and humoral immune functions decrease significantly after 6 months, and the risk of secondary infection increases.

ObjectiveTo explore the molecular mechanism of Yishen Tongluo prescription in inhibiting the apoptosis of glomerular podocytes in rats with membranous nephropathy (MN) based on the miR-514a-5p/tumor necrosis factor superfamily member 15 (TNFSF15) signaling pathway. MethodEighty SD rats were pre-immunized and injected with cationized bovine serum albumin (C-BSA) into the tail vein for inducing MN, and the successfully modeled MN rats were randomly divided into the model group, high-, middle-, and low-dose (26.44, 13.22, 6.61 g·kg-1) Yishen Tongluo prescription groups, and benazepril (10 mg·kg-1) group, with 10 rats in each group, and another 20 healthy rats were classified into the normal group. Rats in each group were gavaged with the corresponding drugs, once a day, for four successive weeks. After the administration, the 24-hour urine total protein (UTP) level, serum total cholesterol (TC), triglyceride (TG), albumin (ALB), creatinine (SCr), and urea nitrogen (BUN) levels were measured. The miR-514a-5p and TNFSF15 mRNA expression levels in the rat kidney tissue were detected by real-time fluorescence quantitative polymerase chain reaction (Real-time PCR), and the expression levels of podocyte marker proteins Nephrin, Podocin, Podocalyxin, Synaptopodin, TNFSF15, and podocyte apoptosis-related proteins B lymphocytoma-2 (Bcl-2)-related X protein (Bax), Bcl-2-associated death promoter (BAD) protein, and B-cell lymphoma-extra large (Bcl-XL) by immunohistochemistry (IHC). Western blot was used to detect the expression levels of TNFSF15, Bax, BAD, Bcl-2, and BCL-XL in the rat kidney tissue. The apoptosis rate of rat kidney tissue was measured using the in situ end labeling method (Tunnel). ResultCompared with the normal group, the level of miR-514a-5p in the kidney tissue was significantly reduced (P<0.05), and the TNFSF15 mRNA expression was significantly increased (P<0.05). The expression levels of podocyte marker proteins Nephrin, Podocin, Podocalyxin, and Synaptopodin were down-regulated (P<0.05). The protein expression levels of TNFSF15, Bax, and BAD were increased (P<0.05), whereas the Bcl-2 and Bcl-XL protein expression levels were decreased (P<0.05). The number of apoptotic cells diminished significantly (P<0.05). Compared with the model group, the level of miR-514a-5p in the kidney tissue was significantly increased (P<0.05), while the level of TNFSF15 mRNA was significantly decreased (P<0.05). The expression levels of podocyte marker proteins Nephrin, Podocin, podocalyxin, and Synaptopodin were up-regulated (P<0.05), whereas the TNFSF15, Bax, and BAD protein expression levels were down-regulated (P<0.05). Bcl-2 and Bcl-XL protein expression levels rose (P<0.05). The number of apoptotic cells significantly decreased (P<0.05). ConclusionYishen Tongluo prescription reduces the apoptosis of rat kidney podocytes and alleviates the kidney injury of MN rats through the miR-514a-5p/TNFSF15 signaling pathway.

ObjectiveTo investigate the analgesic effect and its mechanism of (-)-gallocatechin gallate (EGCG) on high-frequency stimulation (HFS)-induced chronic primary pain in female mice. MethodsThe model of chronic primary pain in female mice were established by HFS of sciatic nerve in left hind limb at 10 V (100 Hz, 0.5 ms, 4 trains of 1-s duration at 10-s intervals). The mice were randomly divided into sham operation group, vehicle (saline) + HFS group, different concentrations of EGCG + HFS groups (4~5 mice in each group). 10 μL EGCG (10, 20, 50, 200 μmol/L) or vehicle was injected intrathecally 1 h before surgery. The therapeutic effect of EGCG was evaluated by paw withdrawal threshold (PWT) and analgesic efficiency. Immunofluorescence of lumbar spinal cord was used to evaluate the possible mechanisms. ResultsCompared with vehicle HFS group, intrathecal administration of EGCG alleviated HFS-induced mechanical allodynia in a dose-dependent manner, and the maximum analgesic efficiency was 84.95%. EGCG also blocked the increases in c-Fos (a marker for neuronal excitability) positive neurons and the expressions of calcitonin gene-related peptide (CGRP+) terminals, Iba1 (a marker for microglia) and GFAP (a marker for astrocytes) in the ipsilateral spinal dorsal horn. ConclusionIntrathecal injection of EGCG exerts an analgesic effect against HFS-induced chronic primary pain, mediated by inhibiting the increases in presynaptic CGRP+ terminals, postsynaptic neuronal excitability and glial activation in the spinal dorsal horn.
