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 incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

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.

OBJECTIVE: To explore the effects of high temperature on learning and memory ability, behavioral activity, and fatigue as well as the intervention effect of compound nutrients on the exercising mice. METHODS: Thirty specific pathogen-free healthy male Kunming mice were randomly divided into the normal-temperature exercise, high-temperature exercise, and high-temperature exercise supplement groups, with 10 mice in each group. The mice in these three groups performed treadmill exercise for one hour every day, six days per week, and continued for four weeks. The mice in the high-temperature exercise supplement group were fed with 0.3 mL of compound nutrients 30 minutes before each treadmill exercise, whereas the mice in the normal-temperature exercise and the high-temperature exercise groups were fed with an equal volume of distilled water. At the end of the treadmill exercise, the mice were subjected to experiments on their neurological behaviors. The serum of mice in each group were collected to detect the lactic acid level, urea nitrogen level, and creatine kinase activity. The liver and gastrocnemius muscle tissues were then taken for detecting the levels of liver glycogen and muscle glycogen.RESULTS: Compared with the mice in the normal-temperature exercise group, the escape latency of the mice in the high-temperature exercise group was prolonged(P<0.05), whereas the number of platform crossings, percentage of target quadrant time, and distance were reduced(all P<0.05). Compared with the mice in the high-temperature exercise group, the escape latency of the mice in the high-temperature exercise supplement group was shortened(P<0.05), whereas the number of platform crossings, percentage of target quadrant time, and distance were increased(all P<0.05). Compared with the mice in the normal-temperature exercise group, the first fall time and grip strength of the mice in the high-temperature exercise group were reduced(all P<0.05), whereas the number of falls was increased(P<0.05). Compared with the mice in the high-temperature exercise group, the first fall time and grip strength of the mice in the high-temperature exercise supplement group were increased(all P<0.05), whereas the number of falls was reduced(P<0.05). Compared with the mice in the normal-temperature exercise group, the serum lactic acid level, urea nitrogen level, and creatine kinase activity of the mice in the high-temperature exercise group were increased(all P<0.05), whereas the levels of liver glycogen and muscle glycogen were decreased(all P<0.05). Compared with the mice in the high-temperature exercise group, the serum lactic acid level, urea nitrogen level, and creatine kinase activity of the mice in the high-temperature exercise supplement group were decreased(all P<0.05), whereas the levels of liver glycogen and muscle glycogen were increased(all P<0.05). CONCLUSION: High temperature exercise can lead to decreased learning and memory ability and behavioral activity in mice, resulting in exercise-induced fatigue. Supplemental compound nutrients can prevent these changes.

BACKGROUND: Shenyankangfu Tablet (SYKFT) is a Chinese patent medicine that has been used widely to decrease proteinuria and the progression of chronic kidney disease. OBJECTIVE: This trial compared the efficacy and safety of SYKFT, for the control of proteinuria in primary glomerulonephritis patients, against the standard drug, losartan potassium. DESIGN, SETTING, PARTICIPANTS AND INTERVENTION: This was a multicenter, double-blind, randomized, controlled clinical trial. Primary glomerulonephritis patients, aged 18-70 years, with blood pressure ≤ 140/90 mmHg, estimated glomerular filtration rate (eGFR) ≥ 45 mL/min per 1.73 m MAIN OUTCOME MEASURES: The primary outcome was change in the 24-hour proteinuria level, after 48 weeks of treatment. RESULTS: A total of 735 participants were enrolled. The percent decline of urine protein quantification in the SYKFT group after 48 weeks was 8.78% ± 2.56% (P = 0.006) more than that in the losartan 50 mg group, which was 0.51% ± 2.54% (P = 1.000) less than that in the losartan 100 mg group. Compared with the losartan potassium 50 mg group, the SYKFT plus losartan potassium 50 mg group had a 13.39% ± 2.49% (P < 0.001) greater reduction in urine protein level. Compared with the losartan potassium 100 mg group, the SYKFT plus losartan potassium 100 mg group had a 9.77% ± 2.52% (P = 0.001) greater reduction in urine protein. With a superiority threshold of 15%, neither was statistically significant. eGFR, serum creatinine and serum albumin from the baseline did not change statistically significant. The average change in TCM syndrome score between the patients who took SYKFT (-3.00 [-6.00, -2.00]) and who did not take SYKFT (-2.00 [-5.00, 0]) was statistically significant (P = 0.003). No obvious adverse reactions were observed in any group. CONCLUSION: SYKFT decreased the proteinuria and improved the TCM syndrome scores of primary glomerulonephritis patients, with no change in the rate of decrease in the eGFR. SYKFT plus losartan potassium therapy decreased proteinuria more than losartan potassium therapy alone. TRIAL REGISTRATION NUMBER NCT02063100 on ClinicalTrials.gov.

OBJECTIVES: To study the efficacy of family rehabilitation treatment performed by parents under the guidance of professionals in children with autism spectrum disorder (ASD). METHODS: In the prospective study, 60 children with ASD, aged 24-60 months, were randomly divided into an observation group and a conventional group. The parents of the children in the conventional group received an online training on basic knowledge and rehabilitation training of ASD alone, and those in the observation group received the online training and performed family rehabilitation treatment under the guidance of a professional team. Psycho-Education Profile Third Edition (PEP-3) and Childhood Autism Rating Scale (CARS) were used to evaluate the changes in related abilities after intervention. RESULTS: After 6 months of intervention, the scores of all dimensions of the PEP-3 scale in the observation group and most dimensions of the conventional group significantly increased ( CONCLUSIONS An online training on basic knowledge and rehabilitation training of ASD for parents can improve the abilities and core clinical symptoms of children with ASD. The family rehabilitation treatment model with a team of professionals as the resource platform and parents as the performer has a more significant efficacy on improving the language, sports, and other abilities and alleviating the severity of the symptoms in children with ASD.

The effects of alcohol extracts from roots, stems, leaves, and flowers of Scutellaria Baicalensis Georgi (SBG) on endogenous metabolism in D-gal-induced aging-model rats were investigated by ¹H NMR metabolomics. Results showed that 32 endogenous metabolites were identified in the urine. Combined with the VIP value and t-test, 14 different metabolites were found by multivariate statistical analysis of the spectrum. Compared with the control group, the content of α-ketoglutaric acid, hippuric acid and 3-hydroxybutyrate in the urine of rats in the model group was significantly decreased (P<0.05) and the content of trimethylamine oxide, glycine, alanine, lactic acid, dimethylglycine, acetate, pyruvate, taurine, allantoin, betaine, N-acetylated glycoprotein was significantly increased (P<0.05). The metabolites were mainly derived from taurine and hypo-taurine metabolism; glycine, serine and threonine metabolism; pyruvate metabolism; glycolysis/gluconeogenesis; glyoxylic acid and dicarboxylic acid metabolism; and the tricarboxylic acid cycle. The content of differential metabolites in urine samples was altered by the alcohol extracts from the different parts of SBG. Leaves extracts of SBG had the greatest effect on urine metabolites, and mainly affected taurine and hypo-taurine metabolism; glycine, serine and threonine metabolism; and pyruvate metabolism. This study provides a reliable experimental basis for the future development of SBG. This animal experiment was approved by the Committee on the Ethics of Animal Experiments of Shanxi University (SXULL2016036).
