ObjectiveThis study explores the efficacy and pharmacological mechanism of Wujiwan in rats with inflammatory bowel disease （IBD） from the perspectives of the peroxisome proliferator-activated receptor γ （PPARγ） signaling pathway and T-cell immunity， providing reference for the treatment of IBD with traditional Chinese medicine. MethodThe study involved administering 2，4，6-trinitrobenzenesulfonic acid （TNBS） enemas to 35 rats to induce acute IBD. After 24 hours， the animals were divided into the following groups： normal group， model group， Wujiwan treatment group， and positive drug control group. Each group received gastric gavage for 8 consecutive days before the rats were dissected to compare the disease activity index （DAI） of the rat colon tissue， the colon mucosal damage index （CMDI）， and the spleen index. Enzyme-linked immunosorbent assay （ELISA） was used to measure the levels of interleukin-1β （IL-1β）， interleukin-10 （IL-10）， and tumor necrosis factor-α （TNF-α） in the serum. Quantitative real-time polymerase chain reaction （Real-time PCR） was used to determine the mRNA expression levels of T-bet （T-box expressed in T cells） and Gata3 （Gata-binding protein-3） in the colon tissue. Western blot analysis was conducted to detect the protein expression levels of PPARγ， T-bet， and nuclear factor-κB p65 （NF-κB p65） in the rat colon. ResultThe rat model of IBD was successfully established. Compared with the model group， the Wujiwan treatment group showed reduced DAI， CMDI， and spleen index， decreased content of TNF-α in the serum（P<0.01）， significantly increased content of IL-10（P<0.01）， and elevated mRNA content of T-bet and Gata3（P<0.05） in the colon tissue. The expression of PPARγ protein was augmented（P<0.05）， and the expression of T-bet and NF-κB p65 protein was decreased（P<0.05，P<0.01）. ConclusionWujiwan activates or upregulates PPARγ expression in IBD rats to inhibit the generation of pro-inflammatory factors， participates in the inflammatory immune process， and alleviates inflammatory reactions. Its mechanism may involve regulating the NF-κB pathway through PPARγ， enhancing Th2 cell transcription expression， and reducing Th1 cell transcription.

Traditional Chinese medicine （TCM） has a long history of application in China and has consistently played a vital role in treating diseases and saving lives. TCM prescriptions （compounds） constitute the primary form of clinical TCM treatment and significantly differ from western medicine （chemicals） due to the diverse composition and chemical constituents of TCM （compounds）. Nevertheless， the potential multi-component， multi-target， and multi-pathway action characteristics of TCM prescriptions also demonstrate their possible （complementary） therapeutic advantages when compared with single-component chemical drugs. Therefore， driven by the development of modern science and technology and the demands of the modernization and internationalization of TCM， modern theories regarding the complexity of TCM prescription effects have been continuously proposed： Different from the abstract language of traditional prescription theory， the modern TCM prescription theory is more inclined to illustrate the connotation of prescription compatibility concretely and vividly from an experimental and scientific perspective. In this paper， new theories on the complexity of TCM prescriptions proposed in recent years are summarized to provide research references and ideas for the greater role of TCM prescriptions and a better scientific understanding.

Demyelination of the central nervous system often occurs in neurodegenerative diseases， such as multiple sclerosis （MS）. The myelin sheath， a layer of myelin membrane wrapping the axon， plays a role in the rapid conduction and metabolic coupling of impulses for neurons. The exposure of the axon will lead to axonal degeneratio， and further neuronal degeneration， which is the main cause of dysfunction and even disability in patients with demyelinating neurodegenerative diseases. In addition to the demyelination of mature myelin sheath， remyelination disorder is also one of the major reasons leading to the development of the diseases. The myelin sheath is composed of oligodendrocytes （OLs） derived from oligodendrocyte progenitor cells （OPCs） which are differentiated from neural stem cells （NSCs）. The process of myelin regeneration， i.e.， remyelination， is the differentiation of NSCs into OLs. Recent studies have shown that this process is regulated by a variety of genes. MicroRNAs， as important regulators of neurodegenerative diseases， form a complex regulatory network in the process of myelin regeneration. This review summarizes the main molecular pathways of myelin regeneration and microRNAs involved in this process and classifies the mechanisms and targets. This review is expected to provide a theoretical reference for the future research on the treatment of demyelinating diseases by targeting the regulation of microRNAs.

ObjectiveTo investigate the effects of Jiaohong pills （JHP） and its prescription， Pericarpium Zanthoxyli （PZ） and Rehmanniae Radix （RR） cognitive dysfunction in scopolamine-induced Alzheimer's disease （AD） mice and its mechanism through pharmacodynamic and metabolomics study. MethodThe animal model of AD induced by scopolamine was established and treated with PZ， RG and JHP， respectively. The effects of JHP and its formulations were investigated by open field test， water maze test， object recognition test， avoidance test， cholinergic system and oxidative stress related biochemical test. Untargeted metabolomics analysis of cerebral cortex was performed by ultra-performance liquid chromatography-Quadrupole/Orbitrap high resolution mass spectrometry （UPLC Q-Exactive Orbitrap MS）. ResultThe behavioral data showed that， compared with the model group， the discrimination indexes of the high dose of JHP， PZ and RR groups was significantly increased （P<0.05）. The staging rate of Morris water maze test in the PZ， RR， high and low dose groups of JHP was significantly increased （P<0.05， P<0.01）， the crossing numbers in the PZ， JHP high and low dose groups were significantly increased （P<0.05， P<0.01）； the number of errors in the avoidance test were significantly reduced in the PZ and high-dose JHP groups （P<0.01）， and the error latencies were significantly increased in the JHP and its prescription drug groups （P<0.01）. Compared with the model group， the activities of acetylcholinesterase in the cerebral cortex of the two doses of JHP group and the PZ group were significantly increased （P<0.05， P<0.01）， and the activity of acetylcholinesterase in the high-dose JHP group was significantly decreased （P<0.05）， and the level of acetylcholine was significantly increased （P<0.01）. At the same time， the contents of malondialdehyde in the serum of the two dose groups of JHP decreased significantly （P<0.05， P<0.01）. The results of metabolomics study of cerebral cortex showed that 149 differential metabolites were identified between the JHP group and the model group， which were involved in neurotransmitter metabolism， energy metabolism， oxidative stress and amino acid metabolism. ConclusionJHP and its prescription can antagonize scopolamine-induced cognitive dysfunction， regulate cholinergic system， and reduce oxidative stress damage. The mechanism of its therapeutic effect on AD is related to the regulation of neurotransmitter， energy， amino acid metabolism， and improvement of oxidative stress.

ObjectiveTo study the plasma pharmacokinetics and tissue distribution of five representative components in Wujiwan， and to illustrate the difference of metabolism and tissue distribution before and after compatibility. MethodHealthy male SD rats were divided into four groups， including Wujiwan group（A group， 62.96 g·L^-1）， Coptidis Rhizoma group（B group， 38.4 g·L^-1）， processed Euodiae Fructus group（C group， 5.88 g·L^-1） and fried Paeoniae Radix Alba group（D group， 18.68 g·L^-1）， with 65 rats in each group， and were administered the drugs according to the clinical dose of decoction pieces converted into the dose of the extracts. Then plasma， liver， small intestine and brain were taken at pharmacokinetic set time in each group after administration. Ultra-high performance liquid chromatography-triple quadrupole tandem mass spectrometry was developed for the quantitative analysis of five representative components［berberine（Ber）， palmatine（Pal）， evodiamine（Evo）， rutecarpine（Rut） and paeoniflorin（Pae）］ in Wujiwan， their concentrations in plasma， liver， small intestine and brain were detected at different time， plasma samples were processed by protein precipitation， and tissue samples were pretreated by protein precipitation plus liquid-liquid extraction. Non-atrioventricular model was used to calculate the pharmacokinetic parameters of each component， and the parameters of each group were compared. ResultPharmacokinetic results of A group showed that area under the curve（AUC_0-t） of the five representative components were ranked as follows：Ber and Pal were small intestine>liver>blood， Evo and Rut were liver>small intestine>plasma， Pae was small intestine>plasma， which was not detected in the liver， no other components were detected in brain except for Ber. In comparison with plasma and other tissues， peak concentration（C_max） of Ber， Pal， Evo， and Rut were the highest and time to peak（t_max） were the lowest in the liver of A group. In plasma， the AUC_0-t and C_max of Evo and Rut were increased in A group compared with C group， t_max of Pea was elevated and its C_max was decreased in A group compared with D group. In the liver， compared with B-D groups， C_max values of 5 representative components except Pae were elevated， AUC_0-t of Pae was decreased and AUC_0-t of Evo and Rut were increased in the A group. In the small intestine， half-life（t_1/2） of each representative components in A group was elevated and t_max was decreased， and C_max of each representative ingredient except Pal was decreased， AUC_0-t values of Ber and Pal were increased， whereas the AUC_0-t values of Evo and Rut were decreased. ConclusionThe small intestine， as the effector organ， is the most distributed， followed by the liver. The pharmacokinetic parameters of the representative components in Wujiwan are changed before and after compatibility， which is more favorable to the exertion of its pharmacodynamic effects.

value for T2DM complicated with CAS plaque.

Objective To investigate the main dietary patterns of children in urban areas of Maanshan City, and to explore the association between dietary patterns and subthreshold autism trait (SAT), attention-deficit/hyperactivity disorder (ADHD) symptoms and comorbid behaviors in 3-year-old children. Methods Based on the birth cohort of Maanshan Maternal and Infant Health from June 2015 to June 2016，regular physical examinations were conducted from 4 to 2 to 1, and follow-up was conducted until the age of 3. A semi-quantitative food frequency questionnaire was employed to assess dietary intakes. SAT and ADHD symptoms were assessed by Clancy autism behavior scale (CABS) and the 10-item Chinese version of the Conners Abbreviated Symptom Questionnaire (C-ASQ). Social-demographic information was also collected. Results The detection rates of SAT, ADHD symptoms, and comorbidity were 11.03%, 5.28%, and 2.71%, respectively. The older the father, the higher the mother's education level, and the higher the per capita monthly income of the family, the lower the SAT detection rate (P<0.05). The higher the father's educational level, the lower the detection rate of ADHD symptoms (P<0.05). The older the mother and the higher the education level, the lower the detection rate of comorbid behavior in their children (P <0.05). After adjusting for demographic influencing factors, the low intake level was used as a reference. The vegetarian type with moderate intake level was negatively correlated with SAT, while the processed food type with high intake level was positively correlated with SAT. The vegetarian type with high intake level was negatively correlated with ADHD symptoms, while the snack type with high intake level was positively correlated with ADHD symptoms. The vegetarian type with high intake level was negatively correlated with comorbidity. Conclusion Unhealthy dietary patterns are related to children's SAT and ADHD symptoms. Correcting children's unhealthy eating patterns may help reduce children's behavior problems.

The aim of this study is to investigate the effect of Mito TEMPO on the preservation of porcine semen in liquid form.The preservation solution was supplemented with 0,0.5,5.0,50.0,and 500.0 μmol/L of Mito TEMPO,and the diluted boar semen was stored at 17 ℃ for 1 to 5 days.After preservation,we measured sperm motility,acrosome integrity,plasma membrane integrity,reactive oxygen species(ROS)content,total antioxidant capacity,and mitochondrial membrane potential.The fertilization ability and embryonic development potential of sperm preserved for 5 days were assessed using an in vitro fertilization test.The results indicated that the addition of 5.0,50.0 μmol/L of Mito TEMPO to the preservation solution significantly reduced ROS content and improved sperm motility,plasma membrane integrity,acrosome integrity,mitochondrial membrane potential,and antioxidant capacity.Furthermore,it enhanced the fertilization and embryonic devel-opment potential of the preserved sperm.Therefore,Mito TEMPO is beneficial for the preservation of porcine semen in liquid form and may serve as a foundation for the development of liquid semen preservation solutions.
