In this study, we investigated the anti-inflammatory effect and mechanism of tilianin in lipopolysaccharide (LPS)-induced RAW264.7 cells. The cell viability was detected by cell counting kit-8 (CCK-8) assay. The content of tumor necrosis factor α (TNF-α) and interleukin-6 (IL-6) were detected by enzyme-linked immuno sorbent assay (ELISA) kits. The content of nitric oxide (NO) was assayed by Griess reagent method. The level of intracellular reactive oxygen species (ROS) was detected by 2',7'-dichlorodihydrofluorescein diacetate (DCFH-DA) fluorescent probe. The protein levels of Toll like receptor 4 (TLR4), myeloid differentiation primary response gene 88 (Myd88), nuclear factors κB p65 (NF-κB p65), phosphorylated nuclear factor κB p65 (p-NF-κB p65), nuclear factor κB inhibitory protein α (IκBα) and phosphorylation nuclear factor κB inhibitory protein α (p-IκBα) were detected by Western blot. The mRNA and protein levels of NLRP3, pro-IL-1β, pro-IL-18 and pro-caspase-1 were detected by qRT-PCR and Western blot. Immunofluorescence staining was used to detect the nuclear translocation of NF-κB p65. The effect of tilianin on the TLR4/Myd88/NF-κB signaling pathway was further validated by using the TLR4 signaling inhibitor restatorvid (TAK242). The results showed that tilianin significantly reduced the levels of TNF-α, IL-6 and NO in the supernatant of RAW264.7 cells and decreased the content of intracellular ROS. Tilianin reduced the levels of TLR4, Myd88, p-NF-κB p65 and p-IκBα protein and nuclear translocation of NF-κB p65. Tilianin could reduce the protein levels of NLRP3, pro-IL-1β, pro-IL-18 and pro-caspase-1. Tilianin significantly inhibited the mRNA levels of NLRP3 and pro-IL-1β. The above research results indicated that tilianin could significantly alleviate the LPS-induced inflammatory response in RAW264.7 cells and its mechanism might be related to downregulate the TLR4/Myd88/NF-κB signaling pathway to inhibit NLRP3 inflammasome.

Acute mitral regurgitation(MR)in the setting of myocardial infarction(MI)may be the result of papillary muscle rupture(PMR).The clinical presentation can be catastrophic,with refractory cardiogenic shock.This condition is associated with high morbidity and mortality.Transcatheter edge-to-edge repair(TEER)has become increasingly common in treating severe mitral regurgitation.This case details a successful TEER is feasible and safe in patients with acute MR following MI.TEER is an emerging treatment option in this clinical scenario that should be taken into consideration.

The effect of Tujia medicine Berberidis Radix on endogenous metabolites in the serum and feces of mice with ulcerative colitis(UC) induced by dextran sulfate sodium(DSS) was analyzed by metabolomics technology to explore the metabolic pathway and underlying mechanism of Berberidis Radix in the intervention of UC. The UC model was induced in mice by DSS. Body weight, disease activity index(DAI), and colon length were recorded. The levels of tumor necrosis factor-α(TNF-α) and interleukin-10(IL-10) in colon tissues were determined by ELISA. The levels of endogenous metabolites in the serum and feces were detected by ultra-high-performance liquid chromatography coupled to quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS). Principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were employed to characterize and screen differential metabolites. The potential metabolic pathways were analyzed by MetaboAnalyst 5.0. The results showed that Berberidis Radix could significantly improve the symptoms of UC mice and increase the level of the anti-inflammatory factor IL-10. A total of 56 and 43 differential metabolites were identified in the serum and feces, respectively, belonging to lipids, amino acids, fatty acids, etc. After the intervention by Berberidis Radix, the metabolic disorder gradually recovered. The involved metabolic pathways included biosynthesis of phenylalanine, tyrosine, and tryptophan, linoleic acid metabolism, phenylalanine metabolism, and glycerophospholipid metabolism. Berberidis Radix can alleviate the symptoms of mice with DSS-induced UC, and the mechanism may be closely related to the re-gulation of lipid metabolism, amino acid metabolism, and energy metabolism.

OBJECTIVE: To compare the effect of acupuncture based on syndrome differentiation and estazolam in the treatment of chronic insomnia and its influence on cognitive function. METHODS: A total of 90 patients with chronic insomnia were randomly divided into an acupuncture group and a medication group, 45 cases in each group. The acupuncture group was treated with acupuncture at Sishencong (EX-HN 1) and bilateral Shenmen (HT 7), Sanyinjiao (SP 6) combined with compatibility of acupoints based on syndrome differentiation, once a day for 6 d and then rest for 1 d, for a total of 4 weeks. The medication group was treated with oral estazolam tablets before bedtime, 1 tablet each time, for a total of 4 weeks. Before and after treatment, the scores of Pittsburgh sleep quality index (PSQI), mini-mental state examination (MMSE), Montreal cognitive assessment (MoCA) and auditory verbal memory test (AVMT) of the two groups were compared, and the effects were evaluated. RESULTS: After treatment, the PSQI sub-item scores and total scores of the two groups were lower than those before treatment ( P<0.05 ), and above scores in the acupuncture group were lower than those in the medication group ( P<0.05 ); the scores of MMSE, MoCA and AVMT in the two groups were higher than those before treatment ( P<0.05 ), and the scores in the acupuncture group were higher than those in the medication group ( P<0.05 ). The total effective rate of the acupuncture group was 80.0% (36/45), which was higher than 53.3% (24/45) in the medication group (P<0.05). CONCLUSION Syndrome differentiation acupuncture can improve the sleep quality and cognitive function of patients with chronic insomnia, and the curative effect is better than that of estazolam.

This study adopted headspace-gas chromatography-mass spectrometry(HS-GC-MS) and electronic nose to detect volatile components from Myristicae Semen samples with varying degrees of mildew, aiming at rapidly identifying odor changes and substance basis of Myristicae Semen mildew. The experimental data were analyzed by electronic nose and principal component analysis(PCA). The results showed that Myristicae Semen samples were divided into the following three categories by electronic nose and PCA: mildew-free samples, slightly mildewy samples, and mildewy samples. Myristicae Semen samples with different degrees of mildew greatly varied in volatile components. The volatile components in the samples were qualitatively and quantitatively detected by HS-GC-MS, and 59 compounds were obtained. There were significant differences in the composition and content in Myristicae Semen samples with different degrees of mildew. The PCA results were the same as those by electronic nose. Among them, 3-crene, D-limonene, and other terpenes were important indicators for the identification of mildew. Bicyclo[3.1.0]hexane, 4-methylene-1-(1-methylethyl)-, terpinen-4-ol, and other alcohols were key substances to distinguish the degree of mildew. In the later stage of mildew, Myristicae Semen produced a small amount of hydroxyl and aldehyde compounds such as acetaldehyde, 2-methyl-propionaldehyde, 2-methyl-butyraldehyde, and formic acid, which were deduced as the material basis of the mildew. The results are expected to provide a basis for the rapid identification of Myristicae Semen with different degrees of mildew, odor changes, and the substance basis of mildew.

Qixuehe Capsules is a compound Chinese patent medicine developed for treating the disorder of Qi and blood(a common etiology of gynecological disease), which has remarkable effects on smoothing liver and regulating Qi, activating blood circulation, and relieving pain. However, due to its complex prescriptions(15 herbs) and multiple effects, the quality control of Qixuehe Capsules has always been a bottleneck problem limiting its sustainable development. Therefore, this study adopted the traditional Chinese medicine Q-markers quantitative identification system established previously by our research group based on the combination of analytic hierarchy process and entropy weight methods. With the different effects of Qixuehe Capsules as the entry point, the comprehensive scores of chemical ingre-dients in Qixuehe Capsules under the items of effectiveness(smoothing liver and regulating qi, activating blood circulation, and relieving pain), testability and specificity were calculated and integrated, respectively. Subsequently, through the analysis of compatibility relationship of Qixuehe Capsules, 15 active ingredients with high comprehensive scores were found to be the top Q-mar-kers of Qixuehe Capsules, including ferulic acid, quercetin, caffeic acid, kaempferol, rutin, Z-ligustilide, senkyunolide Ⅰ, vanillic acid, protocatechuic acid, chlorogenic acid, rosmarinic acid, senkyunolide A, gallic acid, tetrahydropalmatine and eugenol. Collectively, this study not only provided scientific evidence for further research on the improvement and standardization of quality standards of Qixuehe Capsules but also provided methodological references for the quantitative identification of Q-markers of multi-effect traditional Chinese medicine formulae.

Objective: To compare the efficacy of different treatment protocols in treating transient synovitis of the hip (TSH) in children and to optimize the clinical treatment strategy for this condition. Methods: Ninety kids with TSH were divided into a control group, a chiropractic group and a chiropractic plus foot bath group using the random number table method, with 30 cases in each group. The control group was treated with conventional traction; the chiropractic group was given chiropractic treatment based on the control group; the chiropractic plus foot bath group was given Chinese medicine foot bath based on the chiropractic group. Traction and foot bath were conducted once daily while chiropractic was done once every other day, all with 14 d as a treatment course for a total of two courses. Changes in the visual analog scale (VAS) score and range of motion (ROM) of the hip joint in the three groups were observed, and the efficacy was compared. Results: The total effective rate was 93.3％ in the chiropractic plus foot bath group, versus 76.7％ in the chiropractic group and 66.7％ in the control group, and the total effective rate was notably higher in the chiropractic plus foot bath group than in the other two groups (both P<0.05). Respectively after the first and second treatment course, the VAS score decreased significantly in each of the three groups compared with that before treatment (all P<0.01), and the ROM of the hip joint in flexion increased significantly (all P<0.01). After two treatment courses, the VAS score was lower in the chiropractic plus foot bath group than in the other two groups (both P<0.05), and its ROM of the hip joint in flexion was larger than that in the other two groups (both P<0.05). Conclusion: Based on traction, chiropractic plus Chinese medicine foot bath can effectively reduce pain and improve motor function of the hip joint in treating TSH.
