ObjectiveTo understand the status of parasitic infection in the food sold on market in Qingpu District of Shanghai, and to provide an evidence for the development of prevention and control strategies for parasitic infection applicable to Qingpu District. MethodsAquatic products, meat products and other foodstuffs sold on online shops, at farm product markets, supermarkets/foodstores and restaurants were sampled in Qingpu District, Shanghai, during 2015‒2023, based on the administrative division of Qingpu District. The parasitic infection in the food samples were examined using pressing method and digestion for detecting metacercariae in freshwater products and pickled products, using dissection microscopy for Anisakis larvae in seawater products, Taenia cysticercus and Trichinella encysted larvae in meat products. ResultsA total of 1 079 samples of food products were examined during 2015‒2023, with a total parasite infection rate of 13.44%. The total parasite infection rate of freshwater fish products was 3.40% (16/471), and the difference of parasite infection rates between different freshwater fish species was statistically significant (χ²=229.609, P=0.001). The total infection rate of Clonorchis sinensis was 3.18% (15/471), which had been detected in Pseudorasbora parva, Cyprinidae rhodeus, and Carassius auratus, with a positive rate of 77.78% (7/9), 50.00% (5/10) and 3.90% (3/77), respectively. Metorchis orientalis was detected in in Pseudorasbora parva, with a positive rate of 33.33% (3/9). The positive rate of Gnathostoma spinigerum (third-stage larvae) was 0.81%. Paragonimus metacercariae were not detected in the freshwater shrimps and crabs. The infection rate of seawater fish products was 26.46%. The difference of parasite infection rate in seawater fishes was statistically significant (χ²=109.181, P=0.001). A total of 53 pork and beef samples were tested, none was detected with Trichinella larva cysts, Taenia solium metacercariae, and Taenia saginata metacercariae. The total infection rate of pickled yellow mud snail products was 58.11% (43/74). Paragonimus metacercariae was not detected in any of the pickled aquatic product samples. ConclusionThere are different degrees of parasitic infection in freshwater products, seawater products and pickled aquatic products in Qingpu District of Shanghai. The risk of parasite infection from raw or undercooked foods is high. Health education on healthy dietary practices such as throughly cooked food should be strengthened for local residents.

Objective:To construct a novel respiratory syncytial virus (RSV) vaccine based on a recombinant influenza virus vector and evaluate its immune protective effects in mice.Methods:A recombinant H1N1 influenza A virus (IAV) expressing the extracellular domain (Gecto) of RSV A2 G protein was constructed and rescued, named as PR8NAGecto/WSN. After in vitro verification of the Gecto expression and PR8NAGecto/WSN growth kinetics, a single dose of PR8NAGecto/WSN was used to immunize BALB/c mice through intranasal administration to evaluate the efficacy of PR8NAGecto/WSN by assessing humoral (IgG, neutralizing antibody), mucosal (IgA) and cellular immunity (IFN-γ ELISPOT). Four weeks after immunization, the mice were challenged with RSV A2 or RSV B9320 to evaluate the protective effects of PR8NAGecto/WSN by analyzing mouse body weight changes, lung tissue virus titers and pathological changes. Results:A single-dose intranasal immunization with PR8NAGecto/WSN induced robust humoral, mucosal and cellular immunity in mice. Moreover, the mice in the immunized group had lower lung virus loads and mild lung pathological damages following the challenge with RSV A or RSV B subtype as compared with the control group.Conclusions:A single-dose intranasal immunization with PR8NAGecto/WSN induces robust immunity and provide protection against RSV A and B challenges in mice. This study provides new ideas and reference for the development of novel mucosal vaccines against RSV.

Objectives:To explore the effect and possible mechanisms of mild hypothermia on interferon(IFN)-α2b-induced AC16 cardiomyocytes apoptosis. Methods:Cardiomyocytes were stimulated in ordinary temperature and mild hypothermia by IFN-α2b under different concentrations for different times.Proliferation activity of cardiomyocytes was detected by CCK-8 assay.Apoptosis was detected by flow cytometry technique.The effects of different interventions on mitochondrial morphology were examined using Mito-Tracker Green and laser scanning confocal microscope,respectively.The mitochondrial membrane potentials under different intervention conditions were detected by flow cytometry.The fusion of dynamin-related protein 1(Drp1)and mitochondria,and the effects of different interventions on the mitochondria was examined by Drp1 or mitochondrial fluorescent probes and laser scanning confocal microscope.The effects of different intervention conditions on the protein expression level of Phospho-Drp1(p-Drp1)Ser616,Drp1,cleaved poly ADP-ribose polymerase1(cleaved-PARP1),poly ADP-ribose polymerase1(PARP1)were detected by Western blot. Results:CCK-8 assay and flow cytometry results showed that IFN-α2b inhibited the proliferation and enhanced the apoptosis of AC16 cardiomyocytes in a time and dose-dependent manner,these effects could be attenuated by mild hypothermia.Mito-Tracker Green,laser scanning confocal microscope and flow cytometry results showed that the extent of damage of mitochondria with different interventions were attenuated in the setting of mild hypothermia as compared with ordinary temperature.The morphology of mitochondria remained intact and the mitochondrial membrane potentials were the highest in mild hypothermia group.Injured AC16 cardiomyocytes released Drp1 from cytoplasm to mitochondria and increased mitochondrial fission,these effects were abolished after mild hypothermia.p-Drp1 Ser616/Drp1 ratio and cleaved-PARP1/PARP1 ratio were decreased after mild hypothermia,and above effects could be reversed by mitochondrial division inhibitor-1(Mdivi-1)pretreatment. Conclusions:Mild hypothermia inhibits IFN-α2b-induced AC16 cardiomyocytes apoptosis via improving mitochondrial function.

The clinical efficacy advantages of traditional Chinese medicine （TCM） compound prescriptions have always been inadequately characterized in experimental research，which has become a bottleneck restricting the development of TCM pharmacology and even the progress of TCM. The concept of simultaneous treatment/regulation，guided by the theory of mutual generation and restriction of five zang-organs，has guiding significance in the clinical practice of TCM throughout history and is still widely used in the current clinical practice. However，this unique and clinically valuable diagnostic and therapeutic medication system based on the syndrome differentiation has been completely ignored in the modern research of TCM pharmacology，which might be one of the key factors restricting the pharmacological characterization of the therapeutic advantages of TCM compound prescriptions. On the basis of systematically summarizing the phased progress and achievements of the efficacy evaluation of TCM compound prescriptions，this article explores the path of exploring the pharmacological advantages of TCM compound prescriptions on simultaneous treatment/regulation on the basis of the correlation patterns of five zang-organs，from the theory of Zangxiang，the core concept of five zang-organs，and the TCM disease recognition based on the theory of mutual generation and restriction of five zang-organs. With the heart-lung correlation as a breakthrough point，this study explored a new characterization method for the pharmacological advantages of TCM，aiming to provide new ideas for evaluating the efficacy of TCM compound prescriptions.

ObjectiveTo investigate the regulatory effect of Changju Zhidong prescription on gut microbiota structure of children with tic disorder（TD）. MethodTwenty-four children with TD who visited the pediatric outpatient clinic of Dongzhimen Hospital of Bejjing University of Chinese Medicine from November 2020 to January 2022 were selected as the observation group， and eight healthy children were selected as the normal group. The observation group was treated with Changju Zhidong prescription for 12 weeks， and the clinical efficacy was observed by Yale global tic severity scale（YGTSS）， traditional Chinese medicine（TCM） syndrome score， and score of TCM symptom evaluation scale for pediatric gastrointestinal tract. Meanwhile， The fecal samples of the observation and normal groups were collected before and after treatment， and 16S rDNA sequencing was used to explore the effects of Changju Zhidong prescription on the distribution of gut microbiota of the children. ResultCompared with the pre-treatment， the YGTSS， TCM syndrome score， and score of TCM symptom evaluation scale for pediatric gastrointestinal tract of the observation group were significantly reduced after 12 weeks of treatment（P<0.05）， Simpson and Pieloue indices in alpha diversity were significantly reduced（P<0.05）. Before treatment， the relative abundance of Streptococcus parasanguini in the observation group was significantly higher than that of the normal group， while the relative abundances of Citrobacter， Lactobacillus， Lacticaseibacillus， Muribaculaceae unclassified， Odoribacter and 7 other bacterial groups were significantly lower than that in the normal group. Compared with the pre-treatment， the observation group showed a significant decrease in Ruminococcus torques group unclassified and Ruminococcus torques group， and a significant increase in Olsenella， Acetivibrio and 4 other bacterial groups. Functional enrichment analysis showed that the main pathways of Changju Zhidong prescription regulating gut microbiota were bacterial secretion system， insect hormone biosynthesis， limonene and pinene degradation， novobiocin biosynthesis， tropane piperidine and pyridine alkaloid biosynthesis. ConclusionThe pathogenesis of children with TD is accompanied by intestinal flora disorders， and Changju Zhidong prescription can improve core and gastrointestinal symptoms， increase the abundance of beneficial and decrease the abundance of harmful gut microbiota in children with TD， and its mechanism may be through the metabolism of terpenoids and polyketides.

With the rapid development of social economy， the number of patients with nervous system diseases has increased， and the incidence of the population has a trend of younger， which has a serious impact on life health and social economy. Artemisinin is an active antimalarial component extracted and isolated from Artemisia annua， a Chinese medicinal material. Artemisinin and its derivatives， in addition to the antimalarial effect， also have anti-parasitic， anti-fungal， anti-viral， hypoglycemic， hypolipidemic， anti-tumor， and anti-inflammatory effects， showing a wide range of pharmacological activities. In the past five years， research on the new pharmacological effects of artemisinin and its derivatives has been deepening， and the efficacy of artemisinin and its derivatives in nervous system diseases has attracted much attention， including anti-neuroinflammation， anti-oxidative stress， maintaining the stability of the blood-brain barrier， regulating the release of neurotransmitters， repairing neuronal damage， and promoting neuronal regeneration. These pharmacological effects indicate that artemisinin and its derivatives are potentially capable of neuroprotection. By sorting out literature on the pharmacological activity of artemisinin and its derivatives in nervous system during 2019－2024， this paper systematically summarized the protective effects of artemisinin and its derivatives against nervous system diseases such as stroke， neurodegenerative diseases， neuroimmunological diseases， neuralgia， and nervous system tumors. This review is expected to provide clues and evidence for new indication expansion of artemisinin drugs， innovative drug development， and clinical treatment of nervous system diseases.

The impact of air pollution on human health has always been a research hotspot in the global health field. Outdoor air pollutants composed of multiple components can enter the human body through various pathways. Cardiovascular diseases are a group of diseases caused by outdoor air pollutants. Studies have shown that the incidence of cardiovascular diseases， including hypertension， arrhythmia， and heart failure， is significantly increased among people exposed to air pollution environments. Air pollutants such as fine particulate matter， nitrogen dioxide， ozone， carbon monoxide， and sulfur dioxide are closely related to the occurrence of cardiovascular diseases， and short-term and long-term exposure causes different cardiovascular risks. By reviewing the relevant research reports from 2019 to 2024， this article summarizes the epidemiological evidence of cardiovascular diseases caused by different air pollutants. It generalizes the pathways through which air pollutants accelerate the progression of cardiovascular diseases. These pathways include oxidative stress， inflammatory response， thrombosis， extracellular vesicle release， endoplasmic reticulum stress， apoptosis， endothelial dysfunction， autonomic nervous system imbalance， and their interactions. Based on the different mechanisms of air pollution on cardiovascular diseases， the article analyzes the main progress in drug intervention and summarizes the roles of various active ingredients and compound prescriptions of traditional Chinese medicine in treating air pollution-related cardiovascular diseases， providing reference for the research on the mechanisms and drug interventions of air pollution-related cardiovascular diseases.

The complex pathophysiological mechanisms between diabetes mellitus and cardiovascular diseases have not yet been fully elucidated， becoming one of the challenges in clinical care. Glucagon-like peptide-1 receptor agonist （GLP1-RA） and sodium glucose cotransporter-2 inhibitors （SGLT2） are clinically used to reduce the cardiovascular risk of patients with diabetes mellitus. Traditional Chinese medicine has diverse biological activities and unique advantages in the treatment of chronic complex diseases due to its multi-component and multi-target effects. Based on recent reports， this paper reviewed the common risk factors of diabetes mellitus and cardiovascular diseases （e.g.， hyperglycemia， insulin resistance， and inflammation）， related targets such as apolipoprotein C-Ⅲ （APOC3）， S100 calcium-binding protein A8/A9 （S100A8/A9）， growth/differentiation factor-15 （GDF-15）， and NACHT， LRR， and PYD domains-containing protein 3 （NLRP3）， advanced glycation end products， insulin resistance， endothelial dysfunction， endoplasmic reticulum stress， mitochondrial dysfunction， and intestinal flora disorder. In addition， this paper summarized the research progress in the treatment of cardiovascular diseases in diabetes mellitus with the active ingredients （e.g.， baicalein， puerarin， curcumin， notoginsenoside， and tanshinone Ⅱ_A）， single herbal medicines （e.g.， Astragali Radix， Ginseng Radix et Rhizoma， Sophorae Flavescentis Radix， Cinnamomi Cortex， and Corni Fructus）， and compound formulas （e.g.， Buzang Tongluo Fang， Yiqi Yangyin Huoxue Fang， Shenqi Fang， Huangqisan， Danggui Buxue Tang， and Liuwei Dihuang Wan） of traditional Chinese medicine. Traditional Chinese medicine mainly treats cardiovascular diseases in diabetes mellitus by reducing inflammation and oxidative stress， ameliorating dyslipidemia and insulin resistance， protecting islet β cell function， repairing endothelial damage， inhibiting smooth muscle cell proliferation， foam cell formation， macrophage polarization， and cardiac hypertrophy and fibrosis， and regulating intestinal flora disorder. These processes involve insulin receptor substrate/ phosphatidylinositol 3-kinase/protein kinase B （IRS/PI3K/Akt）， peroxisome proliferator-activated receptor α/γ （PPAR α/γ）， nuclear factor-kappa B （NF-κB）， adenosine 5′-monophosphate （AMP）-activated protein kinase （AMPK）， hypoxia-inducible factor-1-BCH domain-containing protein （HIF-1-BNIP）， vascular endothelial growth factor/hypoxia-inducible factor-1α （VEGF/HIF-1α） and other signaling pathways. This review is expected to provide a theoretical basis and reference for the treatment of cardiovascular diseases in diabetes mellitus with traditional Chinese medicine.
